root 640db8c63c Phase 26 — Mem0 upsert + Letta geo hot cache 
Closes the two remaining 2026-era memory findings. Both are
optimizations per J's framing — not load-bearing, but good data
hygiene + future-proofing at scale.

MEM0 UPSERT (data hygiene):
Before: /seed always appended. A scenario re-running the same
operation on the same day wrote duplicate entries, inflating the
playbook corpus with near-identical rows.

Now: upsert_entry(new) inspects existing non-retired entries and
decides ADD / UPDATE / NOOP:
  ADD     → no matching (operation, day, city, state) tuple, append
  UPDATE  → match exists with different names → merge (union, stable
            order), refresh timestamp, keep original playbook_id so
            citations stay valid
  NOOP    → match exists with identical names → skip, return id

Day-granularity keying on timestamp YYYY-MM-DD means intraday
re-seeds dedup but tomorrow's same-operation is a fresh ADD. Retired
entries don't block new seeds — they're out of scope anyway.

Seed endpoint returns {outcome: {mode, playbook_id, merged_names?},
entries_after}. Append=false retains old replace-all semantics.

5 unit tests pass: first_seed_is_add, identical_reseed_is_noop,
same_day_different_names_updates_and_merges, different_day_same_op_is_add,
retired_entry_doesnt_block_new_seed.

Live verified: three successive seeds with (Alice), (Alice),
(Alice, Bob) left entry count unchanged at 1936 with merged names
{Alejandro, Lauren, Alice, Bob}. Previously would have been 3
appends.

LETTA GEO HOT CACHE (scale primitive):
Added geo_index: HashMap<(city_lower, state_upper), Vec<usize>>
alongside PlaybookMemoryState. Rebuilt on every mutation: set_entries,
retire_one, retire_on_schema_drift, upsert_entry, load_from_storage.

compute_boost_for_filtered_with_role now uses the index for O(1) geo
lookup instead of scanning all entries. At current scale (1.9K) the
scan was sub-ms; at 100K+ the scan becomes the dominant cost. The
hot cache future-proofs without adding an LRU abstraction.

Retired entries excluded from index; valid_until still checked on the
hot path since it can elapse between rebuilds.

Owns cloned PlaybookEntries in the geo_filtered vector so the state
read-lock is released before cosine scoring — avoids lock contention
on the scoring path.

root 138592dc56 Spec v2 — all chapters aligned with Phases 19-25 
Full audit pass on devop.live/lakehouse/spec. Five chapters were
stale, one had an outright incorrect line. Scope was bigger than
ch6 alone — J asked "you want to update all" and the honest answer
was yes.

Ch 1 (Repository layout):
- mcp-server row gains /memory/query, /models/matrix, /system/summary,
  observer.ts with :3800 listener
- tests/multi-agent/ row lists all new files: kb.ts, normalize.ts,
  memory_query.ts, gen_scenarios.ts, gen_staffer_demo.ts, and the
  colocated unit tests (kb.test.ts, normalize.test.ts)
- NEW config/ row documents models.json as the 5-tier matrix
- data/ row enumerates the four learning-loop directories:
  _kb/, _playbook_lessons/, _observer/, _chunk_cache/

Ch 3 (Measurement & indexing):
- NEW "Model matrix (Phase 20)" subsection — 5-tier table (T1 hot /
  T2 review / T3 overview / T4 strategic / T5 gatekeeper), per-tier
  primary model, frequency, the think:false mechanical finding
  called out with the 650-token reasoning-budget example
- NEW "Continuation primitive (Phase 21)" paragraph
- NEW "Per-staffer tool_level (Phase 23)" section with full/local/
  basic/minimal mapping and the 46pt fill-rate delta from the 36-run
  demo

Ch 7 (Scale story):
- FIX: playbook_memory growth bullet was claiming "No TTL or merge
  policy" — Phase 25 added retirement via valid_until +
  schema_fingerprint + /retire endpoint. Rewritten to name current
  state (1936 entries, active vs retired split exposed).

Ch 8 (Error surfaces):
- Five new rows added to the failure-mode table:
  * Zero-supply city → cloud rescue (Phase 22 item B) with the
    Gary IN → South Bend IN concrete example
  * LLM truncation → generateContinuable (Phase 21)
  * Schema migration → /vectors/playbook_memory/retire (Phase 25)
  * Observer unreachable → scenario silent-skip + append journal
    survivability

Ch 9 (Per-staffer context):
- NEW "Staffer identity + competence-weighted retrieval (Phase 23)"
  section with the competence_score formula and findNeighbors
  weighted_score
- NEW "Auto-discovered reliable-performer labels" section naming
  Rachel D. Lewis (18 endorsements) and Angela U. Ward (19) as
  concrete output of 36-run demo

Ch 10 (A day in the life):
- Added 17:15 timeline entry — Kim using /memory/query with natural
  language, regex normalizer extracting role/city/count in 0ms
- 17:00 entry updated to mention KB indexing + pathway recommendation
  + observer stream
- 22:00 entry updated to mention detectErrorCorrections nightly scan

Ch 11 (Known limits & non-goals):
- FIX: "playbook_memory compaction" bullet rewritten since retirement
  is now wired; reframed as the honest Mem0 UPDATE/NOOP gap
- Added Letta hot cache deferred item with honest "cheap at 1.9K,
  will bite at 100K" framing
- Added Chunking cache (Phase 21 Rust port) deferred item
- Added Observer → autotune feedback wire deferred item (Phase 26+)

Footer bumped v1 2026-04-20 → v2 2026-04-21 with Phase list.

root e0a843d1a5 Phase 25 — validity windows + playbook retirement 
Addresses the load-bearing memory gap J flagged: playbook entries
had timestamps but no retirement semantic. When a schema migration
changed a column or a seasonal contract ended, stale playbooks kept
boosting candidates silently. Zep 2026-era finding — temporal
validity is the single highest-value memory-hygiene primitive.

SCHEMA (PlaybookEntry gains four optional fields, serde default):
  schema_fingerprint  — SHA-256 over dataset (column, type) tuples at
                        seed time. Missing = legacy entry, never
                        auto-retired on drift.
  valid_until         — RFC3339 hard expiry. compute_boost skips
                        entries past this moment.
  retired_at          — Set by retire_one or retire_on_schema_drift.
                        Retired entries excluded from all boost
                        calculations but kept in journal.
  retirement_reason   — Human-readable: "schema_drift: ...",
                        "expired: ...", "manual: ..."

RETRIEVAL PATH (compute_boost_for_filtered_with_role):
  Before geo+cosine, active_entries filter removes anything retired
  OR past valid_until. Uses chrono::Utc::now() once per call, no per-
  entry clock queries.

NEW METHODS on PlaybookMemory:
  retire_one(playbook_id, reason)
  retire_on_schema_drift(city, state, current_fp, reason) — idempotent,
    scopes by (city, state) so a Nashville migration doesn't touch
    Chicago. Skips legacy entries with no fingerprint.
  status_counts() -> (total, retired, failures)

HTTP ENDPOINTS:
  POST /vectors/playbook_memory/retire
    {playbook_id, reason}                        → retire by id
    {city, state, current_schema_fingerprint, reason} → schema drift
  GET  /vectors/playbook_memory/status
    {total, active, retired, failures}

SEED REQUEST extended with optional schema_fingerprint + valid_until
so the orchestrator (scenario.ts) can pass the current schema hash
when seeding, without a round trip through catalogd.

UNIT TESTS (5/5 pass): retire_one_marks_entry_and_persists,
retired_entries_do_not_boost, expired_valid_until_is_skipped,
schema_drift_retires_mismatched_fingerprints_only,
schema_drift_skips_other_cities.

LIVE VERIFIED: /status on current state = 1936 entries, 43 failures.
POST /retire with a sample playbook_id → "retired":1, /status now
reports active=1935, retired=1.

Memory-findings progress: 3 of 5 shipped.

root 3fb3a60da4 Spec ch6 rewrite — 3 learning paths → 7 + honest gap list 
J flagged the spec out of alignment with what's built. Ch6 now
reflects the full current architecture:

- Path 1 (playbook boost) — formula kept; geo+role prefilter
  refinement called out with measured 14× citation lift
- Path 2 (pattern discovery) — unchanged
- Path 3 (autotune agent) — unchanged
- Path 4 (KB + pathway recommender) — Phase 22, file layout
  documented
- Path 5 (cloud rescue on failure) — Phase 22 item B, verified
  stress_01 example cited
- Path 6 (staffer competence-weighted retrieval) — Phase 23,
  competence_score formula included, cross-staffer auto-
  discovered worker labels (Rachel D. Lewis 18× endorsements)
- Path 7 (observer outcome ingest) — Phase 24, :3800 HTTP
  listener + ops.jsonl append journal

Input normalizer + unified /memory/query surface documented as
the "seamless with whatever input" answer, with the 319ms
natural-language latency number.

Honest gaps kept visible in the spec itself, not hidden:
- Zep validity windows (most load-bearing remaining)
- Mem0 UPDATE/DELETE/NOOP ops
- Letta working-memory hot cache

Live at https://devop.live/lakehouse/spec#ch6 after service
restart. Verified post-deploy: geo+role prefilter, 14× delta,
validity windows gap all present in served HTML.
 2026-04-21 00:03:06 -05:00
root 52561d10d3 Input normalizer + unified memory query — "seamless with whatever input" 
J asked directly: "did we implement our memory findings so that our
knowledge base and our configuration playbook [work] seamlessly with
whatever input they're given?" Honest answer tonight was "one of five
findings shipped, normalizer is the blocker." This closes that gap.

NORMALIZER (tests/multi-agent/normalize.ts):
Accepts structured JSON, natural language, or mixed. Returns canonical
NormalizedInput { role, city, state, count, client, deadline, intent,
confidence, extraction_method, missing_fields } for any downstream
consumer.

Three-tier path:
  1. Structured fast-path — already-shaped input skips LLM
  2. Regex path — "need 3 welders in Nashville, TN" parses without LLM.
     City/state parser tightened to 1-3 capitalized words + "in {city}"
     anchor preference + case-exact full-state-name variants to prevent
     "Forklift Operators in Chicago" being captured as the city name
  3. LLM fallback — qwen3 local with think:false + 400 max_tokens for
     inputs the regex can't handle

Unit tests (tests/multi-agent/normalize.test.ts): 9/9 pass. Covers
structured fast-path, misplacement→rescue intent, state-name→abbrev
conversion, regex extraction from natural language, plural role +
full state name edge case, rescue intent keyword precedence, partial
input reporting missing fields, empty object fallthrough, async/sync
parity on clean inputs.

UNIFIED MEMORY QUERY (tests/multi-agent/memory_query.ts):
One function, five parallel fan-outs, one bundle returned:
  - playbook_workers — hybrid_search via gateway with use_playbook_memory
  - pathway_recommendation — KB recommender for this sig
  - neighbor_signatures — K-NN sigs weighted by staffer competence
  - prior_lessons — T3 overseer lessons filtered by city/state
  - top_staffers — competence-sorted leaderboard
  - discovered_patterns — top workers endorsed across past playbooks
    for this (role, city, state)
  - latency_ms — per-source + total
Every branch is best-effort: one source down doesn't break the bundle.

HTTP ENDPOINT (mcp-server/index.ts):
  POST /memory/query with body {input: <anything>} → MemoryQueryResult
Returns the same shape the TS function does. Typed with types.ts for
future UI consumption.

VERIFIED:
  curl POST /memory/query with structured {role,city,state,count}
    → extraction_method=structured, 10 playbook workers, top score 0.878
  curl POST /memory/query with "I need 3 welders in Nashville, TN"
    → extraction_method=regex (no LLM call), 319ms total, 8 endorsements
      for Lauren Gomez auto-discovered as top Nashville Welder

Honest remaining gaps (documented for next phase):
  - Mem0 ADD/UPDATE/DELETE/NOOP — we still only ADD + mark_failed
  - Zep validity windows — playbook entries have timestamps but no
    retirement semantic
  - Letta working-memory / hot cache — every query scans all 1560
    playbook entries
  - Memory profiles / scoped queries — global pool, no per-staffer
    private subsets

2 of 5 findings now shipped (multi-strategy retrieval in Rust, input
normalization + unified query in TS). The remaining 3 are architectural
additions queued as Phase 25 items — validity windows first since it's
the most load-bearing for long-running systems.
 2026-04-20 23:59:05 -05:00
root b95dd86556 Phase 24 — observer HTTP ingest + scenario outcome streaming 
Closes the gap J flagged: observer wraps MCP:3700, scenarios hit
gateway:3100 directly, observer idle at 0 ops across 3600+ cycles.
Now scenarios POST per-event outcomes to observer's new HTTP ingest
on :3800, observer consumes them alongside MCP-wrapped ops, ERROR_
ANALYZER and PLAYBOOK_BUILDER loops see the full picture.

observer.ts:
- Bun.serve() HTTP listener on OBSERVER_PORT (default 3800):
  GET /health    — basic + ring depth
  GET /stats     — total / success / failure / by_source / recent
                   scenario ops digest
  POST /event    — accept scenario outcome, shape it into ObservedOp
                   with source="scenario" + staffer_id + sig_hash +
                   event_kind + role/city/state + rescue flags
- recordExternalOp() — shared ring-buffer insert so the main analyzer
  + playbook builder don't care where the op came from
- ObservedOp extended with provenance fields

persistOp() FIX — old path POSTed to /ingest/file?name=observed_operations
which REPLACES the dataset (flagged in feedback_ingest_replace_semantics.md).
Every op was silently wiping all prior ops. Replaced with append to
data/_observer/ops.jsonl so the historical trace is durable across
analyzer cycles and process restarts.

scenario.ts:
- OBSERVER_URL env (default http://localhost:3800)
- postObserverEvent() helper with 2s AbortSignal.timeout so observer
  being down doesn't block scenario flow
- Per-event POST after ctx.results.push(result), carrying staffer_id,
  sig_hash (via imported computeSignature), event_kind + role + city
  + state + count + rescue_attempted / rescue_succeeded + truncated
  output_summary

VERIFIED:
  curl POST /event → {"accepted":true,"ring_size":1}
  curl GET /stats → {"total":1,"successes":1,"by_source":{"scenario":1},
    "recent_scenario_ops":[{...staffer_id,kind,role}]}

Final v3 demo leaderboard (9 runs per staffer, cumulative 3 batches):
  James (local):   92.9% fill, 36.8 cites, score 0.775 — RANK 1
  Maria (full):    81.0% fill, 26.2 cites, score 0.727
  Sam (basic):     61.9% fill, 28.2 cites, score 0.640
  Alex (minimal):  59.5% fill, 32.2 cites, score 0.631
Honest finding: Alex has MORE citations than Sam despite NO T3 and NO
rescue. Playbook inheritance alone is firing hardest when overseer is
absent. The 59.5% fill rate (up from 0% when qwen2.5 was executor)
proves cloud-exec + playbook inheritance is the floor the architecture
delivers.

Local gpt-oss:20b T3 outperforms cloud gpt-oss:120b T3 by 12pt fill
rate on this workload — cloud overseer paying latency+variance for
no measurable gain, worth flagging in next models.json tune.
 2026-04-20 23:49:30 -05:00
root 137aed64fb Coherence pass — PRD/PHASES updates, config snapshot wired, unit tests 
J flagged the audit: "make sure everything flows coherently, no
pseudocode or unnecessary patches or ignoring any particular part of
what we built." This is that pass.

PRD.md updates:
- Phase 19 refinement block — geo-filter + role-prefilter WIRED with
  citation density numbers (0.32 → 1.38, and 2 → 28 on same scenario).
- Phase 20 rewrite — mistral dropped, qwen3.5 + qwen3 local hot path,
  think:false as the key mechanical finding, kimi-k2.6 upgrade path.
- Phase 21 status block — think plumbing + cloud executor routing
  added after original commit.
- Phase 22 item B (cloud rescue) — pivot sanitizer, rescue verified
  1/3 on stress_01.
- Phase 23 NEW — staffer identity + tool_level + competence-weighted
  retrieval + kb_staffer_report. Auto-discovered worker labels called
  out with real numbers (Rachel Lewis 12× across 4 staffers).
- Phase 24 NEW — Observer/Autotune integration gap DOCUMENTED, not
  fixed. Observer has been idle at 0 ops for 3600+ cycles because
  scenarios hit gateway:3100 directly, bypassing MCP:3700 which the
  observer wraps. This is the honest "we're not using it in these
  tests" signal J surfaced. Fix deferred; gap visible now.

PHASES.md:
- Appended Phases 20-23 as checked, Phase 24 as unchecked gap.
- Updated footer count: 102 unit tests across all layers.
- Latest line updated with 14× citation lift + 46.4pt tool-asymmetry
  finding.

scenario.ts:
- snapshotConfig() was defined but never called. Now fires at every
  scenario start with a stable sha256 hash over the active model set +
  tool_level + cloud flags. config_snapshots.jsonl finally populates,
  which the error_corrections diff path needs to work correctly.

kb.test.ts (new): 4 signature invariant tests — stability across
unrelated fields (date, contract, staffer), sensitivity to role/city/
count changes, digest shape. All pass under `bun test`.

service.rs: 6 Rust extractor tests for extract_target_geo +
extract_target_role — basic, missing-state-returns-none, word
boundary (civilian != city), multi-word role, absent role, quoted
value parse. All pass under `cargo test -p vectord --lib extractor_tests`.

Dangling items now honestly documented rather than silently pending:
- Chunking cache (config/models.json SPEC, not wired) — flagged
- Playbook versioning (SPEC, not wired) — flagged
- Observer integration (WIRED but disconnected) — new Phase 24

root ad0edbe29c Cloud kimi-k2.5 executor for weak tiers + multi-strategy playbook retrieval 
Two coupled changes from the 2026 agent-memory research + tool
asymmetry findings.

SCENARIO (weak-tier cloud substitute):
qwen2.5 collapsed to 0/14 across the basic/minimal tool_levels.
Replace with cloud kimi-k2.5 on Ollama Cloud — same family as k2.6
(pro-tier locked today, on J's upgrade path). Plumb cloud flag
through ACTIVE_EXECUTOR_CLOUD / ACTIVE_REVIEWER_CLOUD into
generateContinuable so executor/reviewer can route to cloud when
tool_level requires. think:false supported by Kimi family.

Tool level mapping (revised):
  full     — qwen3.5 local + qwen3 local + cloud gpt-oss:120b T3 + rescue
  local    — qwen3.5 local + qwen3 local + local gpt-oss:20b T3 + rescue
  basic    — kimi-k2.5 cloud + qwen3 local + local T3, no rescue
  minimal  — kimi-k2.5 cloud + qwen3 local, no T3, no rescue.
             Playbook inheritance alone on the decision path.

This is the honest version of J's "minimal tools still works via
inheritance" hypothesis — with the executor no longer broken at the
tokenizer level, we can actually measure whether playbook retrieval
substitutes for missing overseers.

PLAYBOOK_MEMORY (multi-strategy retrieval):
Zep / Mem0 research shows multi-strategy rerank (semantic + keyword +
graph + temporal) outperforms single-strategy cosine. Lakehouse now
has a two-tier:

  1. Exact (role, city, state) match: skip cosine, assign similarity=1.0,
     take up to top_k/2+1 slots. These are identity-class neighbors —
     the strongest possible signal.
  2. Cosine fallback within the same (city, state) but different role:
     fills remaining slots.

Exposed as compute_boost_for_filtered_with_role(target_geo, target_role).
Backwards-compatible: compute_boost_for_filtered forwards with role=None
so existing callers keep their current behavior.

Service.rs wires both: extract_target_geo and extract_target_role pull
from the executor's SQL filter. grab_eq_value is factored out of
extract_target_geo so both lookups share one parser. Diagnostic log
now prints target_role alongside target_geo for every hybrid_search:

  playbook_boost: boosts=88 sources=39 parsed=39 matched=5
    target_geo=Some(("Nashville", "TN")) target_role=Some("Welder")

Verified: Nashville Welder query returns 5/10 boosted workers in
top_k with clean role+geo provenance.

kimi-k2.6 on current key returns 403 — pro-tier upgrade required.
kimi-k2.5 is the substitute today; swap to k2.6 by renaming one line

root 5e89407939 Phase 23 refinement — per-staffer tool_level variance 
Staffer.tool_level now controls which subsystems a specific run gets:

  full     — qwen3.5 + qwen3 + cloud T3 + cloud rescue
  local    — qwen3.5 + qwen3 + local gpt-oss:20b T3 + rescue
  basic    — qwen2.5 + qwen2.5 + local T3, no rescue
  minimal  — qwen2.5 + qwen2.5, NO T3, NO rescue. Playbook
             inheritance only.

applyToolLevel() mutates module-scoped ACTIVE_* slots each run from the
env defaults, so prior staffer's overrides never leak. Hot-path code
reads ACTIVE_EXECUTOR / ACTIVE_REVIEWER / ACTIVE_T3_DISABLED /
ACTIVE_OVERVIEW_CLOUD / ACTIVE_RETRY_ON_FAIL instead of the baked
constants.

The architectural question this answers: does playbook_memory
inheritance carry enough knowledge to let a weakly-tooled coordinator
still produce usable outcomes? "Minimal" Alex runs qwen2.5 exec + no
reviewer overseer + no cloud rescue. If Alex still fills events at a
reasonable rate, the playbook system is the real knowledge carrier —
the senior stack is nice-to-have, not the sine qua non.

Demo personas mapped:
  Maria (senior, 48mo, full)
  James (mid, 14mo, local)
  Sam (junior, 4mo, basic)
  Alex (trainee, 1mo, minimal)

Same 3 contracts (Nashville downtown, Joliet warehouse, Indianapolis
assembly) across all four → 12 runs. KB + kb_staffer_report.py
leaderboard already wired; competence_score will now reflect real tool
asymmetry instead of LLM sampling variance.

root 6b71c8e9b2 Phase 23 — contract terms + staffer identity + competence-weighted retrieval 
Matrix-index the "who handled this" dimension so top staffers become
the training signal and juniors inherit their playbooks automatically
via the boost pipeline. Auto-discovered indicators emerge from
comparing trajectories across staffers on similar contracts — that was
always the architectural point; this wires the last piece.

ContractTerms:
- deadline, budget_total_usd, budget_per_hour_max, local_bonus_per_hour,
  local_bonus_radius_mi, fill_requirement ("paramount" | "preferred")
- Attached to ScenarioSpec, propagated into T3 checkpoint + cloud
  rescue prompts so cloud reasons about trade-offs (pivot within bonus
  radius first; respect per-hour cap; split across cities when
  fill_requirement=paramount).

Staffer:
- {id, name, tenure_months, role: senior|mid|junior|trainee}
- On ScenarioSpec; logged at scenario start; attached to KB outcome
- Recomputed StafferStats written to data/_kb/staffers.jsonl after
  every run: total_runs, fill_rate, avg_turns, avg_citations,
  rescue_rate, competence_score.
- Competence formula: 0.45*fill_rate + 0.20*turn_efficiency +
  0.20*citation_density + 0.15*rescue_rate. Normalized to 0..1.

findNeighbors now returns weighted_score = cosine × best_staffer_competence
(floored at 0.3 so high-similarity low-competence neighbors still
surface). pathway_recommender prompt shows the top staffer's identity
so cloud knows WHOSE playbook it's synthesizing from.

Demo infrastructure:
- tests/multi-agent/gen_staffer_demo.ts: 4 personas (Maria senior,
  James mid, Sam junior, Alex trainee) × 3 contracts (Nashville Welder,
  Joliet Warehouse, Indianapolis Assembly). 12 scenarios total.
- scripts/run_staffer_demo.sh: runs the 12 sequentially with
  LH_OVERVIEW_CLOUD=1. Post-run calls kb_staffer_report.py.
- scripts/kb_staffer_report.py: leaderboard + cross-staffer worker
  overlap (names endorsed by ≥2 staffers → auto-discovered high-value
  workers). Top vs bottom differential.

gen_scenarios.ts (Phase 22 generator) also now emits contract terms
on 70% of generated specs — future KB batches populate with realistic
constraint patterns instead of bare role+city+count.

Stress scenario from item A intentionally NOT the production test.
Real staffing has constraints; Nashville contract + staffer demo is
the honest test of whether the architecture produces measurable
differential between coordinator skill levels.

Demo batch launched — 12 runs × ~3min each ≈ 40min unattended. Report
emitted after batch.

root a7fc8e2256 Item B — cloud-rescue retry on event failure 
When a scenario event fails (drift abort or other error) and
LH_RETRY_ON_FAIL is on (default when cloud T3 is enabled), ask cloud
for a concrete pivot — new city, role, or count — then re-run the
event with the remediation's fields. Capped at 1 retry per event so a
genuinely-impossible scenario can't burn budget.

requestCloudRemediation(event, result):
- Feeds the same diagnostic bundle T3 checkpoints get (SQL filters,
  row counts, SQL errors, reviewer drift reasons, gap signals).
- Prompt demands structured JSON: {retry, new_city, new_role,
  new_count, rationale}.
- Cloud is instructed to pivot to NEAREST alternate city when
  zero-supply detected, broaden role when uniquely scarce, reduce
  count when clearly unachievable, or return retry=false when no
  pivot seems viable.

EventResult additions:
- retry_attempt, retry_remediation (with rationale + cloud_model +
  duration), retry_result (full inner result shape), original_event.
- If retry succeeded, it becomes the primary result and original_event
  preserves what was attempted first. If retry also failed, the
  primary stays the failure and retry is recorded alongside.

Sanitizer on cloud output: model sometimes emits "Hammond, IN" in
new_city with "IN" in a non-existent new_state field, producing
"Hammond, IN, IN" downstream. Split new_city on comma, take first
token as city, extract state if present after the comma. Original
event's state is the fallback.

VERIFIED on stress_01.json with LH_OVERVIEW_CLOUD=1:
  Without rescue (item A baseline):  1/5 events ok
  With rescue (item B):              3/5 events ok
Gary IN misplacement: drift → cloud proposed South Bend IN → retry
filled 1/1. Rationale stored in retry_remediation for forensics.

Known limits surfaced (future work):
- City-field mangling failed one rescue before the sanitizer landed;
  next run will use the fix.
- Cloud picks alternate cities without knowing ground-truth supply.
  Flint → Saginaw pivoted but Saginaw also had sparse Welders.
  Future: expose a /vectors/supply-estimate endpoint cloud can consult
  before proposing a pivot.

root c21b261877 Item A — stress scenario + enriched T3 diagnostic prompt 
Proves cloud passthrough works end-to-end AND fixes the diagnostic
quality problem that first run surfaced.

STRESS SCENARIO (tests/multi-agent/scenarios/stress_01.json):
Five genuinely hard events with varied failure modes:
- Gary, IN 5× Electrician: ZERO supply (city not in workers_500k)
- Peoria, IL 8× Safety Coordinator: scarce role, initial pool only 5
- Flint, MI 3× Welder: ZERO supply
- Grand Rapids, MI 4× Tool & Die Maker: scarce but solvable
- Gary, IN 1× Electrician misplacement: repeats event 1's impossibility

FIRST RUN (stress v1) — cloud passthrough works, diagnosis vague:
  T3 checkpoint: "Potential drift flags for upcoming role"
  Lesson: "Before dispatching, query pool status. Update turn counter..."
Generic tactical advice that doesn't address the real problem.
Root cause: T3 prompt only saw outcome summary, not the raw
SQL/pool/drift signals the executor had in its log.

DIAGNOSTIC FIX:
- Added LogEntry[] `sharedLog` parameter to runAgentFill so the caller
  retains the trace even when runAgentFill throws drift-abort.
- EventResult gained `diagnostic_log` field populated on both OK and
  FAIL paths.
- extractDiagnostics() pulls SQL filters, hybrid_search row counts,
  SQL errors, and reviewer drift notes from the log.
- Checkpoint prompt now includes FAILURE FORENSICS block for failed
  events: SQL filters attempted, row counts, errors, drift reasons,
  and an explicit teaching note about zero-supply detection.
- Cross-day lesson prompt flags each event with [ZERO-SUPPLY: pivot
  city needed] tag when drift reasons mention "no match"/"no
  candidates"/"0 rows". PRIORITY clause in the prompt tells the model
  its lesson MUST name alternate cities when that tag appears.

SECOND RUN (stress v2 with enriched prompt) — cloud diagnosis sharp:
  T3 after Flint: risk="Zero candidate supply for Welder in Flint"
                  hint="search Welder×3 in Saginaw, MI (≈30 mi) or
                        expand role to Metal Fabricator"
  T3 after Gary:  risk="Zero supply for Electrician in Gary, IN"
                  hint="Pivot to Chicago, IL (≈40 min); broaden to
                        Electrical Technician within 60 min radius"
  Lesson: specific, per-city, with distances, role-broadening
  fallback, and pre-loading strategy — actionable for item B retry.

Cloud 120b call latencies consistent: 4.8-8.0s per prompt. Cloud
passthrough proven under stress.

Fill outcomes unchanged (1/5 — correct rejection of three impossible
events + one propagating JSON emission edge case on retry pivot
reasoning). The knowledge to rescue them now exists in the lesson;
item B wires the retry.

root a663698571 Item 3 — geo-filtered playbook boost; diagnostic logging 
ROOT CAUSE (found via instrumentation, not hunch):
After a 20-scenario corpus batch, only 6/40 successful (role, city)
combos ever triggered playbook_memory citations on subsequent runs.
Added `playbook_boost:` tracing::info! line in vectord::service to log
boost map size vs candidate pool vs match count. One query revealed:

  boosts=170 sources=50 parsed=50 matched=0

170 endorsed workers came back from compute_boost_for — but zero were
in the 50-candidate Toledo pool. The boost map was pulling globally-
ranked semantic neighbors (top-100 playbooks across ALL cities),
dominated by Kansas City / Chicago / Detroit forklift playbooks the
Toledo SQL filter would never admit. The mechanism was correct at the
per-playbook level; the problem was pool intersection.

FIX (surgical, not cap-tuning):
- playbook_memory::compute_boost_for_filtered(): accepts optional
  (city, state) filter. When set, skips playbooks from other geos
  BEFORE cosine-ranking, so top-k is within the target city.
- Backwards-compatible: compute_boost_for() calls the filtered variant
  with None — existing callers unchanged.
- service::hybrid_search(): extracts target (city, state) from the
  executor's SQL filter via a small parser (extract_target_geo),
  passes to compute_boost_for_filtered.

VERIFIED:
  Before fix: boosts=170 sources=50 parsed=50 matched=0   (0% hit)
  After fix:  boosts=36  sources=50 parsed=50 matched=11  (22% hit)
Top-k=10 now has 7/10 boosted workers with 2-3 citations each.
Boost values 0.075-0.113 on cosine scores 0.67-0.74 — meaningful
reorder without saturation.

scripts/kb_measure.py:
Aggregator that reads data/_kb/*.jsonl and playbooks/*/results.json,
reports fill rate, citation density, recommender confidence trend,
and zero-citation-ok combos (item 3 target signal). Used to measure
before/after on bigger batches.

Diagnostic logging stays — the class of "boosts computed but not
matched" bug can recur if the SQL filter format ever drifts, and
without the counter it's invisible. Every hybrid_search with
use_playbook_memory=true now logs its boost stats.
 2026-04-20 21:35:04 -05:00
root 330cb90f99 Lift k cap, drop ornamental reason field, scenario generator 
ITEM 1 — k CAP + REASON FIELD
The hybrid_search default k was hard-coded to 10. For multi-fill events
(5× expansion, 4× emergency) that's pool=10 → propose 5-of-10, half
the candidates become the answer with no room for rejection. Executor
prompt now instructs k to scale with target_count: k = max(count*5, 20),
cap 80. Default helper bumped 10 → 20.

Fill.reason dropped from required to optional. Nothing downstream ever
consumed it — resolveWorkerIds, sealSale, retrospective all use
candidate_id and name. Models loved to write 100-150 char justifications
per fill; on 4+ fills that blew the JSON budget before the structure
closed. Test 1 run result after this change: FIRST EVER 5/5 on the
Riverfront Steel scenario, 13 total turns across 5 events. The event
that failed last run (emergency 4×Loader with truncated reason-field
continuation) now clears in 2 turns.

Progression:
  mistral baseline:                  0/5
  qwen3.5 + continuation + think:false: 4/5
  qwen3.5 + k=20 + no-reason:        5/5 ✓

ITEM 2 — SCENARIO GENERATOR (NOT YET TESTED E2E)
tests/multi-agent/gen_scenarios.ts emits N deterministic ScenarioSpecs
with varied clients (15 companies), cities (20 Midwest cities known
to exist in workers_500k), role mixes (14 industrial staffing roles,
weighted realistic), and event sequences. Each gets a unique sig_hash
so the KB populates with distinct neighbor signatures.

scripts/run_kb_batch.sh runs all generated specs sequentially against
scenario.ts, logs per-scenario outcomes, and reports KB state at the
end. Each run takes ~2-4min; 20-30 scenarios = 1-2hr unattended.

Next: test the generator+batch on a small N (3-5) to verify KB
populates correctly and pathway recommendations start getting neighbor
signal instead of cold-starts. Then item 3 (Rust re-weighting of
hybrid_search by playbook_memory success).

root 9c1400d738 Phase 22 — Internal Knowledge Library (KB) 
Meta-layer over Phase 19 playbook_memory. Phase 19 answers "which
WORKERS worked for this event"; KB answers "which CONFIG worked for
this playbook signature" — model choice, budget hints, pathway notes,
error corrections.

tests/multi-agent/kb.ts:
- computeSignature(): stable sha256 hash of the (kind, role, count,
  city, state) tuple sequence. Same scenario shape → same sig.
- indexRun(): extracts sig, embeds spec digest via sidecar, appends
  outcome record, upserts signature to data/_kb/signatures.jsonl.
- findNeighbors(): cosine-ranks the k most-similar signatures from
  prior runs for a target spec.
- detectErrorCorrections(): scans outcomes for same-sig fail→succeed
  pairs, diffs the model set, logs to error_corrections.jsonl.
- recommendFor(): feeds target digest + k-NN neighbors + recent
  corrections to the overview model, gets back a structured JSON
  recommendation (top_models, budget_hints, pathway_notes), appends
  to pathway_recommendations.jsonl. JSON-shape constrained so the
  executor can inherit it mechanically.
- loadRecommendation(): at scenario start, pulls newest rec matching
  this sig (or nearest).

scenario.ts:
- Reads KB recommendation at startup (alongside prior lessons).
- Injects pathway_notes into guidanceFor() executor context.
- After retrospective, indexes the run + synthesizes next rec.

Cold-start behavior: first run with no history writes a low-confidence
"no prior data" rec so the signal that something was attempted is
captured. Second run gets "low confidence, 0 neighbors" until a third
distinct sig gives the embedder something to compare against — hence
the upcoming scenario generator.

VERIFIED:
- data/_kb/ populated after one scenario run: 1 outcome (sig=4674…,
  4/5 ok, 16 turns total), 1 signature, 2 recs (cold + post-run).
- Recommendation JSON-parsed cleanly from gpt-oss:20b overview model.

PRD Phase 22 added with file layout, cycle description, and the
rationale for file-based MVP → Rust port progression that matches
how Phase 21 primitives shipped.

What's NOT here yet (batched follow-ups per J's request, tested
between each):
- Lift the k=10 hybrid_search cap to adaptive k=max(count*5, 20)
- Scenario generator to bulk-populate KB with varied signatures
- Rust re-weighting: push playbook_memory success signal INTO
  hybrid_search scoring, not just post-hoc boost

root 0c4868c191 qwen3.5 executor + continuation primitive + think:false 
Three coupled fixes that together turned the Riverfront Steel scenario
from 0/5 (mistral) to 4/5 (qwen3.5) with T3 flagging real staffing
concerns rather than linter advice.

MODEL SWAP
- Executor: mistral → qwen3.5:latest (9.7B, 262K ctx, thinking).
  mistral's decoder emitted malformed JSON on complex SQL filters
  regardless of prompt; J called it — stop using mistral.
- Reviewer: qwen2.5 → qwen3:latest (40K ctx)
- Applied to scenario.ts, orchestrator.ts, network_proving.ts,
  run_e2e_rated.ts

CONTINUATION PRIMITIVE (agent.ts)
- generateContinuable(): empty-response → geometric backoff retry;
  truncated-JSON → continue from partial as scratchpad; bounded by
  budget cap + max_continuations. No more "bump max_tokens until it
  stops truncating" tourniquet.
- generateTreeSplit(): map-reduce for oversized input corpora with
  running scratchpad digest, reduce pass for final synthesis.
- Empty text no longer throws — it's a signal to continuable that
  thinking ate the budget.

think:false FOR HOT PATH
- qwen3.5 burned ~650 tokens of hidden thinking for trivial JSON
  emission. For executor/reviewer/draft: think:false. For T3/T4/T5
  overseers: thinking stays on (that's the point).
- Sidecar generate endpoint accepts `think` bool, passes through to
  Ollama's /api/generate.

VERIFIED OUTCOMES

root 6e7ca1830e Phase 21 foundation — context stability + chunking pipeline 
PRD: add Phase 20 (model matrix, wired) and Phase 21 (context stability,
partial). Phase 21 exists because LLM Team hit this exact wall — running
multi-model ranking on large context silently truncated, rankings
degraded, no pipeline caught it. The stable answer: every agent call
goes through a budget check against the model's declared context_window
minus safety_margin, with a declared overflow_policy when the check
fails.

config/models.json:
- context_window + context_budget per tier
- overflow_policies block: summarize_oldest_tool_results_via_t3,
  chunk_lessons_via_cosine_topk, two_pass_map_reduce,
  escalate_to_kimi_k2_1t_or_split_decision
- chunking_cache spec (data/_chunk_cache/, corpus-hash keyed)

agent.ts:
- estimateTokens() chars/4 biased safe ~15%
- CONTEXT_WINDOWS table (fallback; prod reads models.json)
- assertContextBudget() — throws on overflow with exact numbers, can
  bypass with bypass_budget:true for callers with their own policy
- Wired into generate() and generateCloud() so EVERY call is checked

scenario.ts:
- T3 lesson archive to data/_playbook_lessons/*.json (the old
  /vectors/playbook_memory/seed path was silently failing with HTTP 400
  because it requires 'fill: Role xN in City, ST' operation shape)
- loadPriorLessons() at scenario start — filters by city/state match,
  date-sorted, takes top-3
- prior_lessons.json archived per-run (honest signal for A/B)
- guidanceFor() injects up to 2 prior lessons (≤500 chars each) into
  the executor's per-event context
- Retrospective shows explicit "Prior lessons loaded: N" line

Verified: mistral correctly rejects a 150K-char prompt (7532 tokens
over), gpt-oss:120b accepts it with 90K headroom. The enforcement is
in-band on every call now, not an afterthought.

Full chunking service (Rust) remains deferred to the sprint this feeds:

root 03d723e7e6 Model matrix — 5 tiers, local hard workers + cloud overseers 
config/models.json is the authoritative catalog. Hot path (T1/T2) stays
local; cloud is consulted only for overview (T3), strategic (T4), and
gatekeeper (T5) calls. J named qwen3.5 + newer models (minimax-m2.7,
glm-5, qwen3-next) specifically — all mapped with real reachable IDs
verified against ollama.com/api/tags.

Tier shape:
- t1_hot     mistral + qwen2.5 local       — 50-200 calls/scenario
- t2_review  qwen2.5 + qwen3 local         — 5-14 calls/event
- t3_overview gpt-oss:120b cloud           — 1-3 calls/scenario
- t4_strategic qwen3.5:397b + glm-4.7      — 1-10 calls/day
- t5_gatekeeper kimi-k2-thinking           — 1-5 calls/day, audit-logged

Rate budgets are declared in-config — Ollama Cloud paid tier is generous
but we cap overview/strategic/gatekeeper so no single rogue scenario can
blow the day's quota.

Experimental rotation list wired but disabled by default. When enabled,
T4 randomly routes 10% of calls to a rotating minimax/GLM/qwen-next/
deepseek/nemotron/cogito/mistral-large candidate, logs comparisons, and
auto-promotes after 3 rotations of wins.

Playbook versioning SPEC embedded under `playbook_versioning` key: every
seed gets version + parent_id + retired_at + architecture_snapshot, so
when a schema migration breaks a playbook we can pinpoint which change
retired it. Implementation flagged for next sprint (touches gateway +
catalogd + mcp-server) — not wired here.

- scenario.ts now loads config/models.json at init, env vars still override
- mcp-server exposes /models/matrix read-only so UI can render it

root e4ae5b646e T3 overview tier — mid-day checkpoints + cross-day lesson 
Hot path (T1/T2) stays mistral + qwen2.5. The new T3 tier runs a
thinking model SPARINGLY — after every misplacement, every N-th event
(default N=3), and once post-scenario for the cross-day lesson.

- agent.ts: generateCloud() for Ollama Cloud (gpt-oss:120b etc). Uses
  the same /api/generate shape; thinking field is discarded.
- scenario.ts: runOverviewCheckpoint + runCrossDayLesson. Outputs land
  in checkpoints.jsonl and lesson.md. Lesson also seeds playbook_memory
  under operation "cross-day-lesson-{date}" — future runs pick it up
  through the existing similarity boost.
- Env knobs: LH_OVERVIEW_CLOUD=1 routes T3 to cloud, LH_OVERVIEW_MODEL
  overrides (default gpt-oss:20b local, gpt-oss:120b cloud),
  LH_T3_CHECKPOINT_EVERY controls cadence, LH_T3_DISABLE=1 turns it off.

Why this shape: prior feedback_phase19_seed_text.md warned that verbose
seeds dilute the embedding and silently kill the boost. T3's rich prose
goes to lesson.md; the embedded "approach" + "context" stay terse.

Verified end-to-end: local 20b checkpoint 10.9s, lesson 4.0s; cloud
120b lesson 3.7s. Cloud output is both faster AND more specific than
local (sequenced, tactical, logging advice included).

root af3856b103 Rate/margin awareness: implied pay rate per worker, bill rate per contract 
Closes one of the Path 1 trust-break gaps. The scenario we kept flagging:
recruiter calls the system's top pick, worker quotes $35/hr, contract
pays $28/hr. First broken call kills the demo. This fixes it.

Heuristic (no schema change, derived at query time):
- Per worker: implied_pay_rate = role_base + (reliability × 4) + archetype_bump
  role_base: Electrician $28, Welder $26, Machine Op $24, Maint $26,
    Forklift Op $20, Loader $17, Warehouse Assoc $17, Quality Tech $23,
    Production Worker $18 ...
  archetype bump: specialist +4, leader +3, reliable +1, else 0
- Per contract: implied_bill_rate = role_base × 1.4
  (40% markup — industry norm: pay + overhead + insurance + margin)
- Worker is 'over_bill_rate' when implied_pay_rate > contract's bill_rate
  on a candidate-by-candidate basis

Backend (mcp-server/index.ts):
- ROLE_BASE_PAY_RATE + BILL_MARKUP constants
- impliedPayRate(worker), impliedBillRate(role) functions
- parseWorkerChunk() extracts role/reliability/archetype from vector text
- enrichWithRates() attaches implied_pay_rate on every /vectors/hybrid
  source response. Called from /search and /intelligence/permit_contracts.
- /search accepts optional max_pay_rate number — if set, filters out
  workers above that rate and reports pay_rate_filtered_out count.
- /intelligence/permit_contracts returns implied_bill_rate per contract
  AND over_bill_rate boolean per candidate.

Frontend (search.html):
- Live Contracts cards show 'bill rate: $X/hr' under the headcount line
- Each candidate shows 'pay $X/hr' in the sub-line; red 'Over bill rate'
  chip next to name when their pay exceeds the contract's bill rate
  (hover reveals the exact numbers and why it's flagged)
- Main 'Search all workers' results now include 'pay $X/hr' in the
  why-text (computeImpliedPayRate mirrored client-side to match Bun)

End-to-end verified live:
- Masonry Work permit, bill_rate $25.20/hr
  Kathleen M. Gutierrez pay $25.56/hr → 🔴 OVER
  Melissa C. Rivera pay $20.88/hr → 🟢 OK
- /search with max_pay_rate:32 filtered out 1 Toledo Welder above $32
- Main search shows 'pay $28.64/hr' in each result row

When real ATS data replaces synthetic workers_500k, same UI — the
client's real pay_rate column substitutes for the heuristic.

Phase 8.5 was fully built on the Rust side (WorkspaceManager with
create/handoff/search/shortlist/activity/get/list, persisted to
object storage, zero-copy handoff between agents). Nothing surfaced
it in the recruiter UI. This page closes that gap.

/workspaces — split-pane UI:

Left: scrollable list of all workspaces, sorted by updated_at.
  Each card shows name, tier pill (daily/weekly/monthly/pinned),
  current owner, count of shortlisted candidates + activity events.

Right: selected workspace detail with five sections:
  1. Header — name, tier, owner, created/updated dates, description,
     previous-owners audit trail (each handoff is preserved)
  2. Actions row — Hand off, Shortlist candidate, Save search, Log activity
  3. Shortlist — candidates flagged with dataset + record_id + notes
  4. Saved searches — named SQL queries the staffer wants to rerun
  5. Activity — chronological (newest first) log of what happened

Four modals for the add/edit actions (create, handoff, shortlist,
save-search, log-activity). All forms POST through the existing
/api/* passthrough to the gateway's /workspaces/* routes.

End-to-end verified live:
  1. Sarah creates 'Demo: Toledo Week 17' workspace
  2. Shortlists Helen Sanchez (W500K-4661) with notes about prior endorsements
  3. Logs activity: 'called — Helen confirmed Tuesday 7am shift'
  4. Hands off to Kim with reason 'end of shift'
  5. Kim opens the workspace: owner=kim, previous_owners=[{sarah→kim}],
     sees all 3 prior events + the shortlisted Helen
     — no data copy, pointer swap only (Phase 8.5 design)

Security: all dynamic content built via el(tag,cls,text) DOM helper.
Zero innerHTML on API-derived strings. Modal close-on-backdrop-click
is guarded to the backdrop element.

- file: always on, appends JSONL to mcp-server/data/notifications.jsonl
- webhook: optional, POSTs {text, digest} to configured URL
  (Slack incoming-webhook / Discord webhook / any custom endpoint)

Digest format (human-readable, fits in a Slack message):
  LAKEHOUSE DIGEST — 2026-04-20 23:24
  3 staffing deadlines within window:
    • Production Worker — 2d to 2026-04-23 · demand 724

    • Electrician — 5d to 2026-04-26 · demand 34
  +779 new playbooks (total 779, 2204 endorsed names)
  snapshot: 0 critical · 0 tight · $275,599,326 pipeline

/alerts page:
- Current status table (daemon state, interval, webhook, last run)
- Config form: enable toggle, interval, deadline warn window, webhook
  URL + label (saved to data/notification_config.json)
- 'Fire a test digest now' button — force a cycle without waiting
- Recent digests panel shows the last 10 dispatches with full text

End-to-end verified live:
- Daemon armed successfully on startup
- First-run digest dispatched to console + file in <1s
- Events detected correctly: 3 deadlines within 7 days from real
  Chicago permit data; 779 playbook entries surfaced as memory growth
- Digest text format is Slack-pastable
- Dispatch records appear in /alerts recent list

TDZ caveat: startAlertsDaemon() invocation moved to end of module so
all const/let in the alerts block evaluate before daemon reads them.

root 23eb04a145 Onboarding wizard — ingest any staffing CSV in 3 steps 
New /onboard page. Client-facing wizard for getting real data into
the system without engineering help.

Flow:
1. Drop a CSV (or click 'Use the sample as my data' — ships a 25-row
   realistic staffing roster under /samples/staffing_roster_sample.csv)
2. Browser parses client-side. Columns auto-typed (text/int/decimal/
   date). PII flagged by name hint AND content regex (emails, phones).
   First rows previewed. Read-only — nothing written yet.
3. Name the dataset (lowercase+underscores). Commit.
4. Post-commit: dataset is live. Shows 4 next steps the operator can
   take (SQL query, vector index, dashboard search, playbook training).

Backend:
- /onboard serves onboard.html
- /samples/*.csv serves CSV files from mcp-server/samples/ with
  filename validation (only [a-zA-Z0-9_-.]+.csv, prevents path traversal)
- /onboard/ingest forwards multipart/form-data to gateway /ingest/file
  preserving the boundary. The generic /api/* passthrough breaks
  multipart because it reads as text and forwards as JSON; this route
  uses arrayBuffer + original Content-Type.

Verified end-to-end: upload sample roster (25 rows, 12 columns) →
parse in browser → show columns + PII flags + preview → commit →
gateway writes Parquet, registers in catalog → immediately queryable:
  SELECT * FROM onboard_demo2 LIMIT 3
  → Sarah Johnson, Forklift Operator, Chicago, IL, 0.92
Round-trip <1 second.

Nav updated on all pages to link Onboard. Shipped with a sample CSV
so the full flow is demonstrable without real client data.

When a real client shows up, same path — they upload their CSV.
No engineering ticket, no code change, no schema pre-definition.

Security: sample filename regex prevents path traversal. CSV parse
is client-side pure JS (no DOM injection). Commit uses existing
/ingest/file validation (schema fingerprint, PII server-side,
content-hash dedup).

root 468798c9ac /spec: technical specification — 11-chapter README-equivalent 
J's ask: explain the full architecture so someone reading a README
can dispute it or recreate it. The repo isn't public yet; this page
IS the spec until it is.

Ch1 Repository layout — 13 crates + tests/multi-agent + docs + data,
    with owned responsibility and file path per crate.

Ch2 Data ingest pipeline (8 steps) — sources (file/inbox/DB/cron),
    parse+normalize with ADR-010 conservative typing, PII auto-tag,
    dedup, Parquet write, catalog register with fingerprint gate,
    mark embeddings stale, queryable immediately.

Ch3 Measurement & indexing — row count / fingerprint / owner /
    sensitivity / freshness / lineage per dataset. HNSW vs Lance
    tradeoff table with measured numbers (ADR-019). Autotune loop.
    Per-profile scoping (Phase 17).

Ch4 Contract inference from external signal — Chicago permit feed
    → role mapping → worker count heuristic → timeline → hybrid
    search with boost → pattern discovery → rendered card. All
    pre-computed before staffer opens UI.

Ch5 What a CRM can't do — 11-row comparison table of capabilities.

Ch6 How it gets better over time — three paths:
    - Phase 19 playbook boost (full math)
    - Pattern discovery meta-index
    - Autotune agent

Ch7 Scale story: 20 staffers, 300 contracts, midday +20/+1M surge
    - Async gateway + per-staffer profile isolation + client blacklists
    - 7-step surge handling flow (ingest, stale-mark, incremental refresh,
      degradation, hot-swap, autotune re-enter)
    - Known pain points: Ollama inference serial, RAM ceiling ~5M on
      HNSW (mitigated by Lance), VRAM 1-2 models sequential,
      playbook_memory unbounded.

Ch8 Error surfaces & recovery — 10-row table covering ingest schema
    conflicts, bucket failures, ghost names, dual-agent drift,
    empty searches, Ollama down, gateway restart, schema fingerprint
    divergence. Every failure has a named surface and recovery path.

Ch9 Per-staffer context — active profile, workspace, client blacklist,
    audit trail, daily summary. How 20 staffers don't see the same UI.

Ch10 Day in the life — 07:00 housekeeping → 07:30 refresh → 08:00
     staffer opens → 08:15 drill down → 08:30 Call click → 09:00
     second staffer shares memory → 12:30 surge → 14:00 no-show →
     15:00 new embeddings live → 17:00 retrospective → 22:00
     overnight trials.

Ch11 Known limits & non-goals — deferred (rate/margin, push, confidence
     calibration, neural re-ranker, pm compaction, call_log cross-ref)
     and explicitly out-of-scope (cloud, ACID, streaming, CRM replace,
     proprietary formats, hard multi-tenant).

Also: nav updated on /dashboard, /console, /proof to link /spec.
Every architectural claim in the spec cites either a code path, an
ADR number, or a phase reference so someone skeptical can target
the specific artifact.

root 76bfa2c8d7 /proof: explain the dual-agent recursive architecture with citations 
Previous page was numeric claims without explanations — 'sub-100ms SQL',
'500K vectors in 341ms' etc. Accurate but undefendable without math,
code paths, and ADR references. Expanded to 8 chapters:

Ch1 — Live receipts (unchanged: real gateway tests, pass/fail, timing)

Ch2 — Architecture. 13-crate diagram with per-crate responsibility
      table and file paths. gateway → catalogd/queryd/vectord/ingestd
      + aibridge → object_store. References ADRs 1-20.

Ch3 — Dual-agent recursive consensus loop (NEW)
      - Role specialization (executor=optimist, reviewer=pessimist)
      - Parallel orchestration via Promise.all
      - Recursive: sealed playbooks feed playbook_memory → next query
      - Termination math: sealed | tool-error abort | drift abort |
        turn-cap abort — every path dumps forensic log
      - File refs: tests/multi-agent/agent.ts, orchestrator.ts,
        scenario.ts, run_e2e_rated.ts

Ch4 — Playbook memory feedback loop (NEW)
      - PlaybookEntry shape with embedding
      - Full boost math: similarity * base_weight * decay * penalty
        / n_workers, capped at MAX_BOOST_PER_WORKER
      - Temporal decay (e^-age/30, 30d half-life)
      - Negative signal (0.5^failures)
      - Why k=200: narrow cosine discrimination in nomic-embed-text
      - Evidence: compounding test 0 → 0.250 cap in 3 seeds
      - persist_sql write-through
      - Pattern discovery (Path 2 meta-index)
      - File: crates/vectord/src/playbook_memory.rs

Ch5 — ADR citations for each key choice
      ADR-001, 008, 012, 015, 019, 020 + Phase 19 design note

Ch6 — Live scale data (unchanged: pulled from /proof.json)

Ch7 — Reproduction recipes: curl for health, sql, hybrid with boost,
      patterns, pm stats, and the full dual-agent scenario run

Ch8 — Honest limits (unchanged: synthetic workers_500k, 1K candidates
      misaligned to call_log, 7B model imperfection, no rate/margin)

Every architectural claim now cites either the code path
(crates/.../src/file.rs::fn_name) or the ADR (docs/DECISIONS.md).
Someone disputing the system has specific targets to attack.

Mechanism unchanged: /proof serves mcp-server/proof.html via
Bun.file. /proof.json still returns the live test data the page
consumes client-side.

root 05f2e42c45 Rebuild /console as narrative walkthrough for a skeptical staffer 
Old console was a chat playground. New console is a guided,
chapter-based explanation that a non-technical staffing staffer
can read top-down and finish convinced — without needing to
understand any of the underlying technology.

Six chapters, each loading live data:

1. Right now, this system is already thinking
   Four stats cards pulled live: construction pipeline $, predicted
   worker demand, rows under management, playbooks remembered. Then
   a narrative that names the current alert posture (critical/tight/ok).

2. The demand signal is real, not made up
   Expandable rows per Chicago permit work_type, with a direct link to
   data.cityofchicago.org for verification. Pill labeled LIVE ·
   DATA.CITYOFCHICAGO.ORG leaves no ambiguity.

3. Where your own data would live
   Catalog enumerated with three pill classes:
   - SWAP FOR YOUR DATA (purple) — the synthetic tables that would
     be replaced by the client's ATS/CRM/call-log exports
   - SYSTEM-GENERATED (blue) — playbook memory, threat_intel, kb_*
     produced by the system itself
   Row counts + columns visible. Names it honestly.

4. Watch the system rank candidates in real time
   Takes the freshest Chicago permit, walks the staffer through all
   three steps (derive need → narrow via SQL → rank + boost), shows
   the top-5 workers with why, boost chip, memory chip, timeline,
   and a plain-English narrative of the CRM gap.

5. Every action compounds
   Playbook memory count + sample + narrative about what it means
   when the staffer logs a fill.

6. Try it yourself
   Free-text input hitting /intelligence/chat, renders response
   with memory chip + boost chips + ranked workers.

Security: all API-derived strings go through textContent or
el(tag,cls,text) helper. Zero innerHTML usage on dynamic content.
Passes security reminder hook.

File size: 419 → ~500 lines. Visual style matches the dashboard
(same palette, typography, chip styles) so the two pages feel
like one app.

root bb1b471c67 Predictive staffing forecast + per-contract timeline 
J's ask: move the system from retrospective ranking to predictive
anticipation. Show it tracks the clock, not just the roster.

New endpoint /intelligence/staffing_forecast:
- Pulls 30-day Chicago permit window (200 permits)
- Maps work_type → role via industry heuristic
- Aggregates predicted worker demand per role
- Joins IL bench supply (workers_500k state='IL' group by role)
- Computes coverage_pct, reliable_coverage_pct
- Classifies risk: critical/tight/watch/ok
- Computes earliest staffing deadline per role
  (permit issue_date + 31d = 45d construction start - 14d window)
- Surfaces recent Chicago playbook ops for the role-specific memory

New UI 'Staffing Forecast' section ABOVE Live Contracts:
- Top card: total construction value, permit count, workers needed,
  critical/tight role count
- Per-role rows: demand vs available supply, coverage %, deadline
  with red/amber/green urgency coloring

Per-contract timeline on Live Contracts:
- estimated_construction_start, staffing_window_opens, days_to_deadline
- urgency classification: overdue/urgent/soon/scheduled
- card border colored by urgency
- timeline line explicitly shows recruiter: OVERDUE/URGENT + days count

This is the 'system already thinks about when, not just who' surface
J was asking for. CRMs store; this anticipates.

root 2595d48535 Gap fixes: pattern fallback, narrative citations, call_log plumbing 
Closing trust-breaks surfaced in the strategic audit.

A — MEMORY chip renders even when sparse:
Previously rendered nothing when no trait crossed threshold, which
recruiters would read as "system has no signal." Now explicitly
says "memory is sparse for this role+geo — no trait crossed
threshold" or "no similar past playbooks yet — first fill of this
kind will seed it." Honest when it doesn't know.

B — Removed /intelligence/learn dead endpoint:
Legacy CSV-writer path that destructively re-wrote
successful_playbooks. /log and /log_failure replace it cleanly.
Leaving dead code confuses future maintainers.

C — Narrative tooltips on Endorsed chips:
Hovering the green "Endorsed · N playbooks" chip now fetches
the worker's past operations from successful_playbooks_live and
shows a story: "Maria — past endorsements: • Welder x2 in
Toledo (2026-04-15), • Welder x1 in Toledo (2026-04-18)..."
Falls back to honest "narrative unavailable" if the seed
didn't land in SQL.

D — call_log infrastructure in worker modal:
New "Recent Contact" section queries call_log JOIN candidates by
name. Surfaces last 3 call entries with timestamp, recruiter,
disposition, duration. When empty (which is today's reality —
candidates table only has 1000 rows vs call_log's higher IDs),
shows an honest message about the data gap and what real ATS
integration would unlock.

Honest call: D ships infrastructure. Actual utility depends on
aligning candidate IDs between the candidates table and
call_log — current synthetic data doesn't cross-ref cleanly.
When real ATS data lands, this section becomes the
"system knows who we called yesterday" feature the recruiter
needs.

Deferred (would require a dedicated session):
- Rate awareness (needs worker pay_rate + contract bill_rate)
- Push / background daemon (Slack/SMS/email integration)
- Confidence calibration (needs a probabilistic ranking layer)
 2026-04-20 17:20:22 -05:00
root 1f56630d5d #3: Worker profile modal shows past playbook history 
Click any worker card → modal now includes a 'Past Playbooks' section
that queries successful_playbooks_live for any row where this worker's
name appears in the result field. Shows up to 8 most recent with
operation, timestamp, approach, and context.

When empty: 'No prior playbooks for NAME yet. First placement builds
the first entry.' — makes the institutional-memory claim visible to
the recruiter: the system is tracking everyone, not just the ones
that sealed this session.

Also added Call / SMS / No-show buttons to the modal action row
(matching the card-level buttons from #1). Every worker-card path
now trains the system.

Closes the user-visible side of Phase 19 — patterns surface during
search (Pass A), boosts fire in ranking (Phase 19 core), and now
the worker's own profile shows the full history that informs those
boosts. Institutional memory legibility, per J's ask.
 2026-04-20 16:21:27 -05:00
root cdd12a1438 #2: Per-client worker blacklists 
New endpoints:
- POST   /clients/:client/blacklist            { worker_id, name?, reason? }
- GET    /clients/:client/blacklist            → { client, entries }
- DELETE /clients/:client/blacklist/:worker_id → { removed, total }

Bun /search accepts optional `client` field. When present, loads that
client's blacklist and appends `AND worker_id NOT IN (...)` to the
SQL filter. Zero-cost if unused; clean trust-break avoidance when a
client has previously flagged a worker.

Persistence: mcp-server/data/client_blacklists.json, synchronous
writes via Bun.write. Scale target is hundreds of entries per client
tops — JSON is fine until we hit 10K+ per client.

Verified: worker_id 9326 (Carmen Green) blacklisted for AcmeCorp,
same Chicago Electrician search with client=AcmeCorp returns 196
sql_matches vs 197 without — exactly one excluded.
 2026-04-20 16:20:17 -05:00
root 4aea71d213 #1: Close recruiter feedback loop — Call/SMS/No-show fire /log and /log_failure 
Every worker-card button in the dashboard now trains the Phase 19
system directly:

- Call  → POST /log       (seeds playbook_memory + persists SQL)
- SMS   → POST /log       (same — both count as positive engagement)
- No-show → POST /log_failure (per-worker penalty 0.5^n on future boost)

Buttons flash status (Logged / Flagged / Ghost) for 1.4s on success,
then re-enable. Operation string derived from the worker's role +
city/state parsed from their loc field. The worker's ghost-name
guard on both endpoints ensures nothing invalid lands in memory.

Before: Call/SMS hit a legacy /intelligence/learn CSV write that
didn't affect ranking. No failure capture existed.

Now: recruiter using the app IS the training signal. Tested
end-to-end — pm_entries grew 203 → 391 from a single session of
logged actions.

root 72ee8f006f k=200 on /search and /match too — consistency with compounding default 2026-04-20 15:41:39 -05:00
root 99ab0fe623 A+B: patterns in main search + compounding bump 
A — Patterns surface in main Worker Search:
  /intelligence/chat smart_search fallback now calls /patterns in
  parallel with hybrid, returns discovered_pattern + matched count.
  search.html doSearch renders a green "MEMORY (N playbooks): ..."
  chip above results so every recruiter query shows the meta-index
  dimension, not just live-contract cards.

B — Compounding proven and default-k bumped:
  Direct compounding test on Chicago Electrician:
  - Run 0 (no seeds): Carmen Green not in top-5, boost 0
  - After 3 seeds of identical operation: boost +0.250 (capped),
    3 citations, lifted to #1. Each seed adds 1 citation. Cap
    prevents one worker from dominating future searches.
  - Required k=200 (not 25 or 50) — embedding band is narrow
    (cosines 0.55-0.67 across all playbooks regardless of geo).
  - Bumped defaults on /search, permit_contracts, and smart_search
    to playbook_memory_k=200. Brute-force sub-ms at this scale.
 2026-04-20 15:41:12 -05:00
root 5c39c74fe4 Live Contracts canvas: Chicago permits × workers_500k × playbook patterns 
New devop.live/lakehouse section pairs live public Chicago building
permits with derived staffing contracts, ranked candidates from the
500K worker bench, and meta-index discovered patterns per role+geo.
Makes the Phase 19 boost + Path 2 pattern discovery visible on real
external data, without needing a paying client to demo.

Backend:
- New /intelligence/permit_contracts endpoint
- Fetches 6 recent Chicago permits > $250K from the Socrata API
- Derives proposed fill: 1 worker per $150K of permit value (capped 2-8)
- For each: /vectors/hybrid with use_playbook_memory=true,
  playbook_memory_k=25, auto availability>0.5 filter
- For each: /vectors/playbook_memory/patterns with k=25 min_freq=0.3
- Returns permit + proposed contract + top 5 candidates with boosts
  and citations + discovered pattern + pattern_matched count

Frontend:
- New "Live Contracts" section on search.html between today's sim
  contracts and Market Intelligence
- Per-permit card: cost + work_type + address + proposed role/count
  + pool size + top 3 candidates (with endorsement chip when boost
  fires) + memory-derived pattern ("MEMORY (N playbooks): recurring
  certifications: OSHA-10 47%, Forklift... · archetype mostly: ...")

Real working demo even without paying clients: shows the system
operating on genuinely external data with our synthetic-data-derived
learning applied.
 2026-04-20 15:36:14 -05:00
root f8e8d25b5f Unblock complex scenarios: JSON tolerance + optional question + mistral exec 
parseAction now strips stray `)` before `}` and trailing commas —
qwen2.5 emits those regularly on tool_call outputs; soft-fix beats
retry-loops. hybrid_search no longer hard-requires `question`; defaults
to "qualified available workers" when the model drops it (mistral's
most common failure mode on complex events).

Kept original TOOL_CATALOG shape (args examples only, not full
action envelopes). The verbose few-shot version from the prior
iteration confused mistral into wrapping propose_done as tool_call.

Scenario V7 result: expansion (5 Forklift Ops) and emergency
(4 Loaders) — previously-failing complex events — now seal reliably.
Pool sizes: 687 and 380 from 500K corpus. Patterns endpoint produces
real operator-actionable signals:
  expansion: "recurring certifications: Forklift (40%), OSHA-10 (40%)
             · recurring skills: mill (40%) · archetype mostly: leader
             · reliability median 0.83"
Baseline + recurring are now flaky (inverted trade-off, pure
model-reliability variance).
 2026-04-20 15:28:30 -05:00
root 1274ab2cb3 Scenario harness: Path 1+2 integration + schema hardening 
Upgrades to tests/multi-agent/scenario.ts to exercise the full Path 1+2
feature set on a real warehouse-client week (5 events on one client):

- Hard SCHEMA ENFORCEMENT block in every event's guidance. Prior runs
  had mistral read narrative words ("shift", "recurring", "expansion")
  as SQL column names. Schema is now locked explicitly with valid
  columns listed and CAST guidance for availability + reliability.
- playbook_memory_k bumped 10 → 100 to match server default.
- Canonical short seed text (operation + "{kind} fill via hybrid
  search" + "{role} fill in {city}, {state}"). Verbose LLM rationales
  dilute embeddings and silently kill boost (Pass 1 finding).
- /vectors/playbook_memory/mark_failed fires automatically on
  misplacement events — records the no-shower's failure so future
  searches for same city+role dampen their boost.
- /vectors/playbook_memory/patterns call per event — surfaces what the
  meta-index discovered (recurring certs/skills/archetype/reliability)
  for that query into the dispatch log and retrospective.
- Retrospective now includes a workers-touched audit table (every
  worker who reached a decision, with outcome column) and a
  discovered-patterns-evolution section across events.

Honest limitations this surfaced in the real run:
- mistral's executor prompt-adherence degrades on high-count events
  (5+ fills) and scenario-specific language (emergency/misplacement).
  3 of 5 events aborted via drift guard. Baseline + recurring sealed
  cleanly with real fills + SMS + emails + seeded playbooks.
- worker_id resolution returns "undefined" for some names when name
  matching is ambiguous in workers_500k (multiple workers with same
  name in same city).
 2026-04-20 15:09:14 -05:00
root 95c26f04f8 Path 1 negative signal + Path 2 pattern discovery + name validation 
New:
- /vectors/playbook_memory/patterns: meta-index pattern discovery.
  Given a query, finds top-K similar playbooks, pulls each endorsed
  worker's full workers_500k profile, aggregates shared traits (cert
  frequencies, skill frequencies, modal archetype, reliability
  distribution), returns a human-readable discovered_pattern. Surfaces
  signals operators didn't explicitly query — the original PRD's
  "identify things we didn't know" dimension.
- /vectors/playbook_memory/mark_failed: records worker failures per
  (city, state, name). compute_boost_for applies 0.5^n penalty per
  recorded failure, so 3 failures quarter a worker's positive boost and
  5 effectively zero it. Path 1 negative signal — recruiter trust
  depends on the system NOT recommending people who no-showed.
- Bun /log_failure: validates failed_names against workers_500k
  (same ghost-guard as /log), forwards to /mark_failed.

Improved:
- /log now validates endorsed_names against workers_500k for the
  contract's city+state before seeding. Ghost names (names that don't
  correspond to real workers) are rejected in the response and excluded
  from the seed, preventing silent boost failures.
- Bun /search auto-appends `CAST(availability AS DOUBLE) > 0.5` to
  sql_filter when the caller didn't constrain availability. Opt out
  with `include_unavailable: true`. Recruiter trust bug: surfacing
  already-placed workers breaks the first call.
- DEFAULT_TOP_K_PLAYBOOKS 25 → 100. Direct cosine measurement showed
  similarities cluster 0.55-0.67 across all playbooks regardless of
  geo, so k=25 missed relevant geo-matched playbooks. Brute-force is
  still sub-ms at this size.

Verified end-to-end on live data:
- Ghost names rejected on /log + /log_failure
- Availability filter drops unavailable workers from candidate pool
- Pattern discovery on unseen Cleveland OH Welder query returned
  recurring skills (first aid 43%, grinder 43%, blueprint 43%) and
  modal archetype (specialist) across 20 semantically similar past
  playbooks in 0.24s
- Negative signal: Helen Sanchez boost dropped +0.250 → +0.163 after
  3 failures recorded via /log_failure (34% reduction)
 2026-04-20 14:55:46 -05:00
root 20b0289aa9 /log validates endorsed names + /search auto-appends availability>0.5 
Two gap-fills surfaced by the real test on 2026-04-20:

1. /log no longer seeds endorsed_names that don't exist in workers_500k
   for the contract's (city, state). Previously accepted ghost names
   silently (entry count grew, SQL row landed, but boost never fired
   because no real worker chunk matched the stored tuple). Response now
   reports rejected_ghost_names and explains why seeding was skipped.

2. Bun /search auto-appends `CAST(availability AS DOUBLE) > 0.5` to
   sql_filter when the caller didn't constrain availability themselves.
   Recruiters expect "available workers" by default — surfacing someone
   on an active placement would break trust on first contact.
   Opt out with `include_unavailable: true`.

Verified: ghost names rejected end-to-end, real names accepted, mixed
input handled correctly. Availability filter drops ~10 workers from a
305-row Cleveland OH Welder pool to 295 actually-available.

root 25b7e6c3a7 Phase 19 wiring + Path 1/2 work + chain integrity fixes 
Backend:
- crates/vectord/src/playbook_memory.rs (new): Phase 19 in-memory boost
  store with seed/rebuild/snapshot, plus temporal decay (e^-age/30 per
  playbook), persist_to_sql endpoint backing successful_playbooks_live,
  and discover_patterns endpoint for meta-index pattern aggregation
  (recurring certs/skills/archetype/reliability across similar past fills).
- DEFAULT_TOP_K_PLAYBOOKS bumped 5 → 25; old default silently missed
  most boosts when memory had > 25 entries.
- service.rs: new routes /vectors/playbook_memory/{seed,rebuild,stats,
  persist_sql,patterns}.

Bun staffing co-pilot (mcp-server/):
- /search, /match, /verify, /proof, /simulation/run, MCP tools all
  forward use_playbook_memory:true and playbook_memory_k:25 to the
  hybrid endpoint. Boost was previously dark across the entire app.
- /log no longer POSTs to /ingest/file — that endpoint REPLACES the
  dataset's object list, so single-row CSV writes were wiping all prior
  rows in successful_playbooks (sp_rows went 33→1 in one /log call).
  /log now seeds playbook_memory with canonical short text and calls
  /persist_sql to keep successful_playbooks_live in sync.
- /simulation/run cumulative end-of-week CSV write removed for the same
  reason. Per-day per-contract /seed (added in this session) is the
  accumulating feedback path now.
- search.html addWorkerInsight renders a green "Endorsed · N playbooks"
  chip with playbook citations when boost > 0.

Internal Dioxus UI (crates/ui/):
- Dashboard phase list rewritten through Phase 19 (was stuck at "Phase
  16: File Watcher" / "Phase 17: DB Connector" — both wrong).
- Removed fabricated "27ms" stat label.
- Ask tab examples + SQL default replaced with real staffing prompts
  against candidates/clients/job_orders (was referencing nonexistent
  employees/products/events).
- New Playbook tab exposes /vectors/playbook_memory/{stats,rebuild} and
  side-by-side hybrid search (boost OFF vs ON) with citations.

Tests (tests/multi-agent/):
- run_e2e_rated.ts: parallel two-agent (mistral + qwen2.5) build phase
  + verifier rating (geo, auth, persist, boost, speed → /10).
- network_proving.ts: continuous build → verify → repeat with
  staffing-recruiter profile hot-swap; geo-discrimination check.
- chain_of_custody.ts: single recruiter operation traced through every
  layer (Bun /search, direct /vectors/hybrid parity, /log, SQL,
  playbook_memory growth, profile activation, post-op boost lift).

/intelligence/market pulls real permit data from Chicago Open Data API:
- $9.6B in active construction permits
- O'Hare expansion ($730M), new casino ($580M), transit station ($445M)
- Maps permit types to staffing roles (electrical→Electrician, masonry→Loader)
- Cross-references with our IL worker bench to show coverage gaps
- Electrician gap: only 1,036 reliable vs 63K estimated demand

Datalake page now shows three intelligence layers:
1. Contract simulation with scenario-driven matching
2. Market Intelligence with live permit data + bench analysis
3. System Learning with fill history and detected patterns

The staffing company sees demand forming before the phone rings.

Each simulation fill now logs: role, headcount, city, state, workers matched,
client, start time, and scenario type. One page refresh = ~20 playbook entries.
4 refreshes = 28 entries with patterns already forming.

Fixed activity counters: shows Contract Fills, Searches, and Patterns.
Activity feed now shows the actual fill data with worker names and scenarios.

This is the PRD's learning loop in action — the system records every
successful match so future queries can learn from past decisions.

Learning Loop:
- /intelligence/learn endpoint logs search→selection as playbook entry
- /intelligence/activity returns learning stats, patterns, and recent activity
- Call/SMS buttons trigger logSelection() — records what query led to what pick
- "System Learning" card on main page shows searches logged, patterns detected,
  and recent activity feed with timestamps
- Every search-selection pair becomes institutional knowledge stored in the lakehouse

Smart Search on Main Page:
- doSearch() now routes through /intelligence/chat (smart NL parser)
- Extracts role, city, state, availability, reliability from natural language
- Shows understanding tags so staffer sees what the system parsed
- Returns workers with ZIP codes, availability %, reliability %, archetype
- "reliable forklift operator available in Nashville" → 10 Nashville forklift
  operators with ZIP codes, all 86-98% reliable, all available — 372ms

New page at /lakehouse/console — a $200/hr consultant's intelligence product:

Morning Brief (auto-loads in ~120ms across 500K profiles):
- Workforce Pulse: total, reliable %, elite %, archetype breakdown
- Geographic Bench: state-by-state reliable % with weakest-state alert
- Comeback Watch: 15K improving workers who crossed 80% reliability
- Risk Watch: 5K erratic + 5K silent workers flagged automatically
- Ready & Waiting: available + reliable workers to call first
- Role Supply: 20 roles with supply/available/reliability

Conversational Chat with 5 intelligent routes:
- "Find someone like [Name] but in OH" → vector similarity search
- "Who could handle industrial electrical work?" → semantic role discovery
  (finds workers for roles that DON'T EXIST in the database)
- "What if we lose our top 5 forklift operators?" → scenario analysis
  with risk rating, bench depth, state-by-state breakdown
- "Which workers should we stop placing?" → risk flagging
- Default: hybrid SQL+vector search with LLM summary

Every response shows: query steps, records scanned, response time.
Transparency kills the "AI is making it up" argument.

Urgent contracts now show:
- Red banner with specific reason: 'Client called last night',
  'Emergency coverage — 2 no-shows reported', 'Production surge',
  'Original crew cancelled', etc.
- Action line: 'Need 3 more workers — see suggested replacements below'
  or 'All positions matched — confirm and send shift details now'
- When unfilled: yellow action box with numbered steps:
  '1. Call the workers above, 2. If someone declines the backup
   is ready, 3. Expand search to nearby states'
- FIRST CHOICE worker highlighted with red border
- BACKUP workers labeled and shown after the required headcount

The staffer doesn't see a red circle and wonder. They see:
'Emergency coverage — 2 no-shows. Need 3 more. Here are your
options. Call this person first. If they can't, here's the backup.'

  Step 1 (red): Review pre-matched workers
  Step 2 (yellow): Call first choice — highest match score
  Step 3 (blue): Confirm or replace — backup is ready
  Step 4 (green): Send shift details to confirmed workers

First-choice worker highlighted with red border + label.
Backup workers shown with dimmed styling + 'BACKUP' label.
Urgent cards show ALL matched workers + backups (not just 3).

Non-urgent contracts split into 'In Progress' (still filling)
and 'Ready to Go' (fully staffed) sections.

The staffer doesn't stare at a red label wondering what to do.
They follow the steps: review, call, confirm, send. Done.

matters, HOW sparse data becomes rich data over time, and that
everything runs on hardware they own with zero cloud dependency.

Complete rebuild around 'how did it know that?' moments:

1. NEEDS YOUR ATTENTION — urgent contracts with pre-matched workers.
   Each worker shows WHY they were matched: 'Reliable (85%) ·
   Certified: OSHA-10 · Same city as job site'

2. READY TO CONFIRM — fully matched contracts, just review and send

3. YOUR STRONGEST WORKERS — 95%+ reliability, 'they rarely
   no-show and clients request them back'

4. BENCH STRENGTH ALERT — states with thin reliable worker pools,
   'consider recruiting in these areas'

Every section has: a label (ACTION NEEDED/READY/INSIGHT/HEADS UP),
a headline in plain English, an explanation of HOW the system
knows this, and actionable workers with Call/SMS buttons.

This is what a CRM has never done: anticipate, explain, recommend.
The staffer doesn't search — they respond to intelligence.

Contract cards: urgency dot, progress bar, fill count.
Workers inside: avatar initials, name, role, location, skill/cert
tags (blue/green), archetype (purple), reliability/availability
bars — all ONLY when data exists.

rootandClaude Opus 4.6 13b01fee9f ADR-021: Sparse data trust path — start with nothing, earn everything 
The staffing company said: 'we don't have any of that data.'
They're right. We showed a demo with 18-field profiles and they
have a name and a phone number.

This ADR documents the trust path:
  Phase 1 (Day 1): Work with name + phone + role. That's enough.
  Phase 2 (Week 1-4): Timesheets → reliability. Calls → history.
  Phase 3 (Month 2+): AI starts helping with real earned data.

Key principles:
- Never show empty fields or 0% bars
- Show what's THERE, not what's missing
- Trust indicators: 'based on 3 placements' not just 'Reliability: 87%'
- The system earns data by being useful, not by demanding it upfront

Also created sparse_workers dataset (200 workers, 74% have role,
34% have notes, 5 have ONLY name+phone) for realistic testing.

- Availability bar with color
- Individual Call/SMS buttons per worker

Contract headers show:

Not a CRM search page. A staffing workstation:

Top: Pipeline showing urgent/filling/total/filled at a glance
Main: Contract cards sorted by urgency — each shows:
  - Client, role, headcount, start time
  - Pre-matched workers with names and AI fit scores
  - Call All / Send SMS / Find More action buttons
  - Unfilled contracts at top, filled at bottom
  - 'Find More' opens search pre-filled with that contract's role

Right sidebar:
  - Alerts: erratic workers, expiring certs, system status
  - Recent communications: who confirmed, who's pending
  - Quick stats: total workers, reliable count, coverage

The search is there but collapsed — it's a tool, not the focus.
When they open the page, their day is already organized.

This is what the CRM doesn't do: anticipate, pre-match, organize.
The staffer's expertise is in relationships and judgment calls —
this handles the data mining so they can focus on that.

All gateway endpoints pointed to ethereal_workers_v1 (10K, W- prefix)
instead of workers_500k_v1 (50K, W500K- prefix). Filters appeared
broken because the vector results came from the wrong dataset —
IDs matched numerically but belonged to different workers.

Now: every search, match, and hybrid call uses workers_500k_v1.

5 Welders in OH (Carmen Perry, Janet White, Rachel Miller, etc).

rootandClaude Opus 4.6 f9e2a0bbbe Fix: filters now ALWAYS work — auto-switches to hybrid when set 
The bug: selecting a state filter in AI Search mode did nothing
because HNSW vector search has no concept of SQL WHERE clauses.
Results came back from any state.

The fix: when ANY filter is set (state, role, or reliability > 0.5),
the search automatically switches to hybrid mode which runs the SQL
filter first, then AI-ranks within the filtered set. Users don't
need to know about modes — filters just work.

- 3 modes: AI Search, CRM Keyword, Hybrid (best)
- Clickable examples: 'warehouse help', 'dependable machine operator', etc
- Filters: state, role, min reliability
- Results show: name, role, location, skills, certs, reliability, AI match score
- Hybrid results marked 'SQL verified against database'
- CRM mode shows 0 results with a prompt to try AI Search
- Mobile responsive

rootandClaude Opus 4.6 c53d3f4d14 Proof page: speaks to the staffer, not the engineer 
Rebuilt the page to address a staffing coordinator who's tired of
learning new tools. Opens with "Your Morning Just Got Easier" and
a side-by-side: their current 45-minute routine vs 5 minutes with
pre-matched workers.

Key messaging:
- "This isn't another CRM to learn"
- "We know what your day looks like" (checklist they'll recognize)
- Shows real matched workers WITH names, not abstract metrics
- "It understands what you mean" — warehouse help finds forklift ops
- "It already filtered the junk" — only workers worth calling
- "It runs on YOUR machine" — no cloud, no fees, no data leaving

Technical proof pushed below a divider for the skeptical team.
The staffer sees their contracts and their workers first.

rootandClaude Opus 4.6 dd344c9b38 Proof page: CRM vs AI side-by-side — shows what keywords can't do 
Rebuilt /proof to highlight the actual differentiator:
- Section 01: "What a CRM Does" — SQL keyword search, every CRM has this
- Section 02: "What AI + Vectors Do" — semantic understanding.
  Side-by-side: CRM finds 0 results for "warehouse work" because no
  profile contains that exact text. AI finds 5 verified workers because
  it understands Forklift Operator + Loader = warehouse work.
- Section 03: 673K vectorized chunks, 98% recall, 10M at 5ms
- Section 04: Local GPU, 4 models, no cloud, no API fees

The point: this isn't another CRM search. It's an intelligence layer
that understands MEANING — and it runs entirely on your hardware.

rootandClaude Opus 4.6 937569d188 ADR-020: Universal ID mapping — fix the flat embedding identity problem 
THE REAL PROBLEM: Every new data source produces different doc_id
prefixes in vector indexes (W-, W500K-, W5K-, CAND-). Hybrid search
had to hardcode strip_prefix for each one. New datasets broke hybrid
until someone added another prefix. This violates "any data source
without pre-defined schemas."

THE FIX: IndexMeta.id_prefix — the catalog records what prefix each
index uses. Hybrid search reads it and strips automatically. Legacy
indexes fall back to heuristic stripping. New indexes can set
id_prefix=None to use raw IDs (no prefix, no stripping needed).

This means: ingest a new dataset, embed it, hybrid search works
immediately without code changes. The system is truly source-agnostic.

Also: full ADR document at docs/ADR-020-universal-id-mapping.md
with the three options considered and rationale for the chosen approach.

rootandClaude Opus 4.6 1565f536eb Fix: job tracker field name mismatch — the overnight killer 
ROOT CAUSE: Python scripts polled status.get("processed", 0) but the
Rust Job struct serialized as "embedded_chunks". Scripts always saw 0,
looped forever printing "unknown: 0/50000" for 8+ hours.

Fix (both sides):
- Rust: added "processed" alias field + "total" field to Job struct,
  kept in sync on every update_progress() and complete() call
- Python: fixed autonomous_agent.py and overnight_proof.sh to read
  "embedded_chunks" as primary key

The actual embedding pipeline was working the whole time — 673K real
chunks embedded overnight. Only the monitoring was blind.

One-word bug, 8 hours of zombie output. This is why you test the
monitoring, not just the pipeline.

rootandClaude Opus 4.6 0bd48771ff OVERNIGHT PROOF: real embeddings confirm architecture 
5,000 workers embedded through nomic-embed-text (real, not random).
Results on REAL embeddings:
  HNSW  recall@10: 1.0000  p50: 762us — PERFECT
  Lance recall@10: 0.9500  p50: 6.8ms — better than random vectors
  SQL autonomous: 50/50 (100%)

Key finding: real embeddings IMPROVE Lance recall (0.95 vs 0.80 on
random vectors) because real text embeddings cluster by topic, making
IVF partitions more effective. The concern about degraded recall on
real data was wrong — it's the opposite.

Also discovered: the 50K embedding job DID complete (50K chunks in
234s) but the job progress tracker showed 0/0. The supervisor's
progress reporting has a bug — the actual embedding pipeline works.

Known remaining issue: hybrid search ID matching between workers_500k
(worker_id format) and vector index (W5K-{id} format) needs the
prefix stripping fix applied to the new index.

rootandClaude Opus 4.6 2e455919b7 Overnight proof — 5-step unattended test with real embeddings 
Runs autonomously via cron (every 3 min, state machine):
  1. Embed 500K workers through Ollama nomic-embed-text (~40 min)
     Real embeddings, not random vectors. This is what matters.
  2. Build HNSW + Lance IVF_PQ on real clustered data
  3. Measure recall — HNSW vs Lance on real embeddings
  4. 100 autonomous operations — local model only, no human steering
     Mix: 50 matches + 25 counts + 15 aggregates + 10 lookups
  5. 30 min sustained load — 10 concurrent ops/sec continuously

Currently running: Step 1 active, GPU at 43%, Ollama embedding.
Monitor: tail -f /home/profit/lakehouse/logs/overnight_proof.log
Check: cat /tmp/overnight_proof_state

THE PROOF:
  10,000,000 × 768d vectors
  30 GB Lance dataset on disk
  IVF_PQ index: 173 seconds to build (3162 partitions, 192 sub_vectors)
  Search p50: 5ms — at TEN MILLION vectors
  Search p95: 19ms

  HNSW at 10M would need 29 GB RAM = past the ceiling
  Lance at 10M = 30 GB disk, 5ms search, no RAM constraint

Agent test on 500K workers: 22/22 positions filled (100%)
  Forklift Operator x5, Machine Operator x4, Welder x3,
  Loader x8, Quality Tech x2 — all via hybrid SQL+vector

The architecture holds past the HNSW ceiling. Lance takes over
exactly as ADR-019 designed. This is not theoretical anymore.

7-step autonomous test via cron (every 2 minutes):
  1. Register 10M × 768d Parquet (28.8 GB, already generated)
  2. Migrate Parquet → Lance (proves Lance handles what HNSW can't)
  3. Build IVF_PQ (3162 partitions for √10M, 192 sub_vectors)
  4. Search benchmark (10 searches, measure p50/p95)
  5. Hot-swap profile test (create scale-10m profile, activate)
  6. Agent test (5 contract matches on 500K via gateway, autonomous)
  7. Final report

State machine in /tmp/scale_test_state — each cron invocation picks
up where the last one stopped. Lock file prevents concurrent runs.
All output to /home/profit/lakehouse/logs/scale_test.log.

Bumped upload limit to 512MB for large CSV ingests. Generated and
ingested 500K staffing worker profiles (346MB CSV → 75MB Parquet
in 5.9s).

SQL at 500K: COUNT=35ms, filter+state=67ms, aggregation=80ms,
complex filter=117ms, 10 concurrent=84ms total (10/10 pass).

HNSW memory projection: 500K vectors = 1.5GB RAM (comfortable on
128GB server). Ceiling at ~5M vectors (14.6GB) — Lance IVF_PQ
takes over beyond that as designed in ADR-019.

Hybrid search 500K SQL → 10K vector: 131ms with 6,289 SQL matches
narrowed to 5 vector-ranked results.

Total scale: 2.9M rows across all datasets (500K workers + 2.47M

1. CORS headers on all gateway responses (browser dashboard was
   blocked by same-origin policy)
2. Dashboard JS uses window.location.origin instead of hardcoded
   localhost:3700 (LAN browsers couldn't reach it)
3. Langfuse tracing wired into every gateway request — api() wrapper
   creates spans for each lakehouse call, logGeneration for LLM calls.
   Week simulation now produces 34 observations per run visible in
   Langfuse UI.

7 traces confirmed in Langfuse after restart. Every /sql, /search,

Week simulation engine: 5 business days, 4-8 contracts per day,
3 rotating staffers with handoffs between days. Runs hybrid search
per contract via the gateway. 28 contracts, 108/108 filled (100%),
5 emergencies, 4 handoffs, 3.2s total.

Dashboard at :3700/ — dark theme, shows:
  - Contract cards sorted by priority with match status
  - Day navigation across the work week
  - Week summary stats (fill rate, emergencies, handoffs)
  - Live alerts (erratic/silent workers)
  - Playbook entries
  - Real-time service health + VRAM

Self-orientation (/context) + verification (/verify) endpoints so

rootandClaude Opus 4.6 a001a21902 MCP self-orientation: /context + /verify + architecture resources 
Any agent (Claude Code via MCP stdio, or sub-agents via HTTP :3700)
can now self-orient without human explanation:

GET /context returns:
  - System purpose and name
  - All datasets with row counts
  - All vector indexes with backends
  - Available models and their strengths
  - Complete tool list with rules
  - Current VRAM state

POST /verify fact-checks any claim about a worker against the golden
data. Agent says "worker 1313 is a Forklift Operator in IL with
reliability 0.82" → endpoint returns verified=true/false with exact
discrepancies.

MCP resources (stdio path for Claude Code):
  - lakehouse://system — live system status
  - lakehouse://architecture — full PRD
  - lakehouse://instructions — agent operating manual
  - lakehouse://playbooks — successful operations database
  - lakehouse://datasets — dataset listing

This is the "command and control" layer J asked for: any agent
connecting to this system gets the context it needs to operate
independently. No human intermediary required.

5-layer morning briefing system:
  1. Contract scan: sorts by urgency, shows requirements
  2. Pre-match: hybrid SQL+vector finds workers per contract BEFORE
     the staffer asks. 25/25 positions pre-matched (100%)
  3. Alerts: erratic workers flagged, silent workers needing different
     channels, thin bench by state/role
  4. Suggestions: top available workers not yet assigned, deep bench
     roles that could fill larger orders
  5. Briefing: qwen3 generates natural language action plan

The staffer's job becomes "review and confirm" not "search and compile."
Action queue: 6 contracts ready for one-click outreach.

Outputs structured JSON at /tmp/copilot_briefing.json — any UI
(Dioxus, React, even a Telegram bot) can render this.

This is the co-pilot: AI anticipates needs, surfaces answers,
staffer focuses on relationships and judgment calls.

rootandClaude Opus 4.6 c7e6ab3beb Staffing day simulation: 94% pass, all gates clear, ready for batching 
Multi-model validated simulation: 4 phases with validation gates.
Morning (contract matching): 26/26 filled including 2 emergencies.
Midday (intelligence): classified routing fixes the count/SQL gap —
keyword classifier routes instantly, qwen2.5 generates SQL with
few-shot examples showing exact column semantics.
Afternoon (analytics): 5/5 SQL analytical queries.

Key fix: few-shot SQL prompting. Adding 4 examples with correct
column names (role, state, archetype) takes qwen2.5 from 40% to
80% accuracy on structured questions. The playbook logged this for
future runs.

Models: qwen3 (40K ctx, reasoning), qwen2.5 (fast SQL), nomic
(embed). Query classifier is keyword-based — deterministic, instant,
no LLM overhead for routing decisions.

rootandClaude Opus 4.6 1bee0e4969 Qwen 3 integration + agent plan + playbook loop 
Pulled qwen3 (8.2B, 40K context, thinking, tool-calling). Created
agent-qwen3 profile. Ran structured plan: 5 contracts (16/16 filled
via hybrid), 5 intelligence questions (2/5 — same RAG counting gap).

Key playbook entry generated: "count/aggregation questions must use
/sql not /search. RAG returns 5 chunks from 10K — cannot count the
full dataset." This routing rule is now in the playbooks database
for future agent runs to learn from.

Pattern confirmed across qwen2.5, mistral, AND qwen3: the structured
matching path (hybrid SQL+vector) is production-ready across all
models. The RAG counting gap is a routing problem, not a model
problem — the fix is query classification, not a better model.

Three new systemd services:
- lakehouse-agent (:3700) — REST gateway wrapping all lakehouse tools.
  Clean JSON in/out, no protocol complexity. 9 endpoints: /search,
  /sql, /match, /worker/:id, /ask, /log, /playbooks, /profile/:id, /vram
- lakehouse-observer — watches operations, logs to lakehouse, asks
  local model to diagnose failure patterns, consolidates successful
  patterns into playbooks every 5 cycles
- Stdio MCP transport preserved for Claude Code integration

AGENT_INSTRUCTIONS.md: complete operating manual for sub-agents.
Rules: never hallucinate, SQL first for structured questions, hybrid
for matching, log every success, check playbooks before complex tasks.

Observer loop:
  observed() wrapper timestamps + persists every gateway call →
  error analyzer reads failures + asks LLM for diagnosis →
  playbook consolidator groups successes by endpoint pattern

All three designed for zero human intervention — agents operate,
observer watches, playbooks accumulate, iteration happens internally.

MCP server at mcp-server/index.ts — 9 tools exposing the full
lakehouse to any MCP-compatible model:
  search_workers (hybrid SQL+vector), query_sql, match_contract,
  get_worker, rag_question, log_success, get_playbooks,
  swap_profile, vram_status

The "successful playbooks" pattern: log_success writes outcomes
back to the lakehouse as a queryable dataset. Small models call
get_playbooks to learn what approaches worked for similar tasks —
no retraining needed, just data.

generate_workers.py scales to 100K+ with realistic distributions:
  - 20 roles weighted by staffing industry frequency
  - 44 real Midwest/South cities across 12 states
  - Per-role skill pools (warehouse/production/machine/maintenance)
  - 13 certification types with realistic probability
  - 8 behavioral archetypes with score distributions
  - SMS communication templates (20 patterns)

100K worker dataset ingested: 70MB CSV → Parquet in 1.1s. Verified:
11K forklift ops, 27K in IL, archetype distribution matches weights.

rootandClaude Opus 4.6 352f99de0f Hybrid SQL+Vector search — the gap is closed 
POST /vectors/hybrid takes a question + SQL WHERE clause. Pipeline:
1. SQL filter narrows to structurally-valid candidates (role, state,
   reliability, certs — whatever the caller specifies)
2. Brute-force cosine scores ALL embeddings (not HNSW, which caps at
   ~30 results due to ef_search — too few to intersect with narrow
   SQL filters on 10K+ datasets)
3. Filter vector results to only SQL-verified IDs
4. LLM generates answer from verified-correct records

Tested on the exact query that failed the staffing simulation:
"forklift operators in IL with reliability > 0.8" — SQL found 78
matches, vector ranked the 5 most semantically relevant, LLM
generated an answer citing real workers with actual skills and
certifications. Every source marked sql_verified=true.

This closes the architectural gap identified by the quality eval:
structured precision (SQL) + semantic intelligence (vector) in one
endpoint. The simulation's contract-matching path was already
SQL-pure and worked perfectly; now the intelligence-question path
has the same accuracy.

5 contracts, 16 positions, 10K worker pool. Four agents: Matcher (SQL
+ vector hybrid), Communicator (LLM SMS drafts), Verifier (fact-checks
against golden data), Analyzer (RAG intelligence questions).

Results:
  - SQL matching: 16/16 positions filled, ZERO hallucinations. Every
    worker's name, role, city, state, certifications, and reliability
    score verified against the golden dataset.
  - SMS generation: 16/16 messages drafted with correct worker names.
  - RAG intelligence: retrieval returns semantically similar but
    structurally wrong workers (wrong state, wrong archetype) because
    vector search can't do structured filtering. LLM correctly reports
    context limitations — doesn't hallucinate beyond retrieved chunks.

Key finding: SQL path is production-ready. RAG path needs hybrid
SQL+vector routing — SQL for structured constraints (state, role,
cert, reliability), vector for semantic similarity. That's the
architectural gap to close.

rootandClaude Opus 4.6 f9f92706f3 RAG reranker + manifest bucket fix — quality improvements from eval 
RAG pipeline now includes a cross-encoder rerank step between retrieval
and generation. The LLM re-sorts top-K results by relevance before
they become context. Falls back to original order if model output is
unparseable (~5% with 7B models). Also improved the generation prompt
to be domain-aware ("staffing database") and request specific citations.

Fixed 4 catalog manifests with bucket="data" (pre-federation leftover)
that poisoned the entire DataFusion query context on startup. The
"users", "lab_trials", "meta_runs", and "new_candidates" datasets
now correctly reference bucket="primary". This bug was surfaced by
the quality evaluation pipeline — wouldn't have been found by
structural tests alone.

Three-tier evaluation:
1. NL→SQL with verifiable ground truth (10 questions): 7/10 (70%)
2. RAG with LLM reranker (5 questions): 4/5 (80%)
3. Self-assessment calibration: 2.8/5 avg, NOT calibrated

Real problems surfaced:
- qwen2.5 generates `WHERE vertical = 'Java'` instead of
  `WHERE skills LIKE '%Java%'` without few-shot schema examples
- DataFusion-specific SQL quirks (must SELECT the COUNT in
  GROUP BY queries) trip the model without explicit instruction
- Vector search can't do structured filtering (city, status) —
  needs hybrid SQL+vector routing
- Self-assessment is uncalibrated: wrong answers score higher
  than correct ones (3.0 vs 2.8)

Fixes validated:
- Few-shot examples fix NL→SQL accuracy from 70% → ~90%
- Reranker stage works but needs more diversity in results

across SQL + vector search + RAG, reads its own error pipeline to
generate recursive test scenarios, and iterates.

50/50 tests pass across 2 iterations with zero errors. Error pipeline
flushes failures back to the lakehouse as a queryable dataset so the
next iteration can target weak spots.

The agent IS the proof that the substrate works end-to-end: ingest →
embed → index → search → generate → profile swap → iterate. Every
capability we built today gets exercised in one script.

rootandClaude Opus 4.6 9e6002c4d4 S3 backend for Lance — hybrid operates on real MinIO object storage 
Enabled lance feature "aws" for S3-compatible storage via opendal.
BucketRegistry: added with_allow_http(true) for MinIO/non-TLS S3
endpoints (fixes "builder error" on HTTP endpoints). lakehouse.toml
gains [[storage.buckets]] name="s3:lakehouse" with S3 backend config.

lance_backend.rs: S3 bucket naming convention — buckets with name
prefix "s3:" emit s3:// URIs for Lance datasets. AWS_* env vars
in the systemd unit provide credentials to Lance's internal
object_store.

Verified end-to-end on real MinIO with real 100K × 768d vectors:
  - Migrate Parquet → Lance on S3: 1.7s (vs 0.57s local)
  - Build IVF_PQ: 16.4s (CPU-bound, essentially same as local)
  - Search: ~58ms p50 (vs 11ms local — S3 partition reads)
  - Random doc fetch: 13ms (vs 3.5ms local)
  - Recall@10: 0.835 (randomized IVF_PQ, consistent with local 0.805)
  - Total S3 footprint: 637 MiB (vectors + index + lance metadata)

The "public storage" claim from the PRD is now proven: the hybrid
Parquet+HNSW ⊕ Lance architecture works on S3-compatible object
storage, not just local filesystem.

rootandClaude Opus 4.6 fd4b6836ae IVF_PQ recall harness — closes ADR-019's explicit measurement gap 
POST /vectors/lance/recall/{index} runs an existing harness through
Lance IVF_PQ search and measures recall@k against brute-force ground
truth. Uses the same EvalSet + ground_truth infrastructure as the
HNSW trial system — no new harness format needed.

First real measurement on resumes_100k_v2 (100K × 768d, 20 queries):
  IVF_PQ (316 partitions, 8 bits, 48 subvectors): recall@10 = 0.805
  For comparison — HNSW ec=80 es=30: recall@10 = 1.000

ADR-019 predicted "likely 0.85-0.95" — actual is 0.805. Slightly
below, but now the harness exists to iterate: increase partitions,
try ivf_hnsw_pq, tune subvectors. The measurement infrastructure
is the deliverable, not any specific recall target.

rootandClaude Opus 4.6 59e72fa566 Scalar btree index on doc_id + auto-build during Lance activation 
LanceVectorStore gains build_scalar_index(column) and
has_scalar_index(column). Exposed as POST /vectors/lance/scalar-index/
{index}/{column}. activate_profile auto-builds the doc_id btree
alongside the IVF_PQ vector index when activating a Lance-backed
profile — operators get both indexes without extra API calls.

stats() now reports has_doc_id_index alongside has_vector_index.

Measured on resumes_100k_v2 (100K × 768d): random doc_id fetch
improved from ~5.4ms to ~3.5ms (35% faster). Btree build: 19ms,
+2.7 MB on disk. The remaining ~3ms is vector column materialization,
not index lookup — to close further would need a projection-only
fetch that skips the 768-float vector for text-only RAG retrieval.

rootandClaude Opus 4.6 2592f8fcb3 PDF OCR via Tesseract — scanned documents now ingestible 
Two-tier PDF extraction: lopdf text layer first (fast, digital PDFs),
Tesseract OCR fallback when text extraction yields zero pages (scanned
documents, image-only PDFs). Falls back gracefully if Tesseract isn't
installed — returns an actionable error directing the operator to
`apt install tesseract-ocr tesseract-ocr-eng`.

OCR path: extract embedded XObject /Image streams from each page via
lopdf, detect format from magic bytes (JPEG/PNG/TIFF), write to temp
file, shell out to tesseract with --oem 3 --psm 6 (LSTM + uniform
text block), read output, clean up. Temp files cleaned even on error.

Schema unchanged — both paths produce (source_file, page_number,
text_content) so downstream consumers (chunker, vectord, queryd) work
identically regardless of how text was produced.

Verified: created a synthetic scanned PDF (PIL → image → PDF with no
text layer), ingested via POST /ingest/file. Tesseract recovered the
text with expected OCR artifacts. Queryable via DataFusion SQL.

rootandClaude Opus 4.6 17a0259cd0 Profile-driven Lance routing — vector_backend auto-routes search + activate 
activate_profile: when profile.vector_backend == Lance, auto-migrates
from Parquet if no Lance dataset exists, auto-builds IVF_PQ if no
index attached. Reuses existing Lance dataset on subsequent activations.

profile_scoped_search: routes to Lance IVF_PQ or Parquet+HNSW based
on the profile's declared backend. Callers hit the same endpoint —
the profile abstracts which storage tier serves the query.

Verified: lance-recruiter (vector_backend=lance) and parquet-recruiter
(vector_backend=parquet) both searched the same 100K index through
POST /vectors/profile/{id}/search. Lance returned lance_ivf_pq at
25ms; Parquet returned hnsw at <1ms. Same API surface, different
backends, transparent routing.

rootandClaude Opus 4.6 7c1222d240 Phase E: Scheduled ingest — the substrate runs itself 
Background Scheduler task fires due ingests on interval, records
outcomes, reschedules. Single-flight per schedule_id so a slow run
can't pile up. 10s tick cadence, schedules' own intervals independent.

ScheduleDef persisted as JSON at primary://_schedules/{id}.json,
rebuilt on startup. ScheduleKind supports Mysql and Postgres (both
through existing streaming paths). ScheduleTrigger::Interval is
live; Cron variant defined in the enum but parsing stubbed with a
safe 1h fallback.

next_run_at set to "now" on creation so operators see success or
failure within one tick — no waiting for the first full interval.
run-now endpoint fires even when schedule is disabled (manual
override for testing). Full catalog integration: PII detection,
lineage with redacted DSN, mark-stale + autotune agent trigger.

Verified live: 20s MySQL schedule against MariaDB lh_demo.customers.
Source mutated between runs (added row + updated value). Second
auto-fire picked up both changes (10→11 rows). DataFusion SQL
confirmed mutations in the lakehouse. 6 unit tests pass.

rootandClaude Opus 4.6 0d037cfac1 Phases 16.2 + L2 + 17 VRAM gate + MySQL + 18 Lance hybrid milestone 
Five threads of work landing as one milestone — all individually
verified end-to-end against real data, full release build clean,
46 unit tests pass.

## Phase 16.2 / 16.5 — autotune agent + ingest triggers

`vectord::agent` is a long-running tokio task that watches the trial
journal and autonomously proposes + runs new HNSW configs. Distinct
from `autotune::run_autotune` (synchronous one-shot grid). Triggered
on POST /vectors/agent/enqueue/{idx} or by the periodic wake; ingest
paths now push DatasetAppended events when an index's source dataset
gets re-ingested. Rate-limited (max_trials_per_hour) and cooldown-
gated so it can't saturate Ollama under live load.

The proposer is ε-greedy around the current champion: with prob 0.25
sample random from full bounds, otherwise perturb champion ± small
delta on both axes. Dedup against history. Deterministic — RNG seeded
from history.len() so the same journal state proposes the same next
config (helps offline replay debugging).

`[agent]` config section in lakehouse.toml; opt-in via enabled=true.

## Federation Layer 2 — runtime bucket lifecycle + per-index scoping

`BucketRegistry.buckets` moved to `std::sync::RwLock<HashMap>` so
buckets can be added/removed after startup. POST /storage/buckets
provisions at runtime; DELETE /storage/buckets/{name} unregisters
(refuses primary/rescue with 403). Local-backend buckets get their
root directory auto-created.

`IndexMeta.bucket` (default "primary" via serde) records each index's
home bucket. `TrialJournal` and `PromotionRegistry` now hold
Arc<BucketRegistry> + IndexRegistry; they resolve target store per-
index via IndexMeta.bucket. PromotionRegistry::list_all scans every
bucket and dedups by index_name. Pre-federation indexes keep working
unchanged — they just default to primary.

`ModelProfile.bucket: Option<String>` declares per-profile artifact
home. POST /vectors/profile/{id}/activate auto-provisions the
profile's bucket under storage.profile_root if not yet registered.

EvalSets stay primary-only for now — noted gap, low-risk to extend
later with the same resolver pattern.

## Phase 17 — VRAM-aware two-profile gate

Sidecar gains POST /admin/unload (Ollama keep_alive=0 trick — forces
immediate VRAM release), POST /admin/preload (keep_alive=5m with
empty prompt, takes the slot warm), and GET /admin/vram (combines
nvidia-smi snapshot with Ollama /api/ps). Exposed via aibridge as
unload_model / preload_model / vram_snapshot.

`VectorState.active_profile` is the GPU-slot singleton —
Arc<RwLock<Option<ActiveProfileSlot>>>. activate_profile checks for
a previous profile with a different ollama_name and unloads it
before preloading the new one; same-model reactivations skip the
unload (Ollama no-ops). New routes: POST /vectors/profile/{id}/
deactivate (unload + clear slot), GET /vectors/profile/active.

Verified live: staffing-recruiter (qwen2.5) → docs-assistant
(mistral) swap freed qwen2.5 from VRAM and loaded mistral. nomic-
embed-text persists across swaps because both profiles use it —
free optimization that fell out of the design. Scoped search
correctly 403s cross-profile in both directions.

## MySQL streaming connector

`crates/ingestd/src/my_stream.rs` mirrors pg_stream.rs for MySQL.
Pure-rust `mysql_async` driver (default-features=false to avoid C
deps). Same OFFSET pagination, same Parquet-streaming write shape.
Type mapping per ADR-010: int/bigint → Int32/Int64, decimal/float
→ Float64, tinyint(1)/bool → Boolean, everything else → Utf8 with
fallback parsers for date/time/json/uuid via Display.

POST /ingest/mysql parallel to /ingest/db. Same PII auto-detection,
same lineage capture (source_system="mysql"), same agent-trigger
hook. `redact_dsn` generalized — was hardcoded to "postgresql://"
length, now works for any scheme://user:pass@host/path URL (latent
PII leak fix for MySQL DSNs).

Verified live against MariaDB on localhost: 10 rows × 9 columns of
test data round-tripped through datatypes int/varchar/decimal/
tinyint/datetime/text. PII detection auto-flagged name + email.
Aggregation queries through DataFusion match the source values
exactly.

## Phase 18 — Hybrid Parquet+HNSW ⊕ Lance backend (ADR-019)

`vectord-lance` is a new firewall crate. Lance pulls Arrow 57 and
DataFusion 52 — incompatible with the rest of the workspace's
Arrow 55 / DataFusion 47. The firewall isolates that dep tree:
public API uses only std types (Vec<f32>, Vec<String>, Hit, Row,
*Stats), so no Arrow types cross the crate boundary and nothing
propagates to vectord. The ADR-019 path that didn't ship until now.

`vectord::lance_backend::LanceRegistry` lazy-creates a
LanceVectorStore per index, resolving bucket → URI via the
conventional local-bucket layout. `IndexMeta.vector_backend` and
`ModelProfile.vector_backend` carry the choice (default Parquet so
existing indexes unchanged).

Six routes under /vectors/lance/*:
- migrate/{idx}: convert binary-blob Parquet → Lance FixedSizeList
- index/{idx}: build IVF_PQ
- search/{idx}: vector search (embed via sidecar)
- doc/{idx}/{doc_id}: random row fetch
- append/{idx}: native fragment append
- stats/{idx}: row count + index presence

Verified live on the real resumes_100k_v2 corpus (100K × 768d):
- Migrate: 0.57s
- Build IVF_PQ index: 16.2s (matches ADR-019 bench; 14× faster than
  HNSW's 230s for the same data)
- Search end-to-end (Ollama embed + Lance scan): 23-53ms
- Random doc_id fetch: 5-7ms (filter scan; faster than Parquet's
  ~35ms full-file scan, slower than the bench's 311us positional
  take — would close that gap with a scalar btree on doc_id)
- Append 100 rows: 3.3ms / +320KB on disk vs Parquet's required
  full ~330MB rewrite — the structural win
- Index survives append; both backends coexist cleanly

## Known follow-ups not in this milestone

- ModelProfile.vector_backend doesn't yet auto-route /vectors/profile/
  {id}/search to Lance; callers go through /vectors/lance/* directly
- Scalar btree on doc_id (closes the 5-7ms → ~300us gap)
- vectord-lance built default-features=false → no S3 yet
- IVF_PQ recall not measured (ADR-019 caveat) — needs a Lance-aware
  variant of the eval harness
- Watcher-path ingest doesn't push agent triggers (HTTP paths do)
- EvalSets still primary-only (federation gap)
- No PATCH endpoint to move an existing index between buckets
- The pre-existing storaged::append_log doctest fails to compile
  (malformed `{prefix}/` parses as code fence) — pre-existing bug,
  left for a focused fix

rootandClaude Opus 4.6 4e1c400f5d Phase E.2: Compaction integrates tombstones — physical deletion closes GDPR loop 
Phase E gave us soft-delete at query time (tombstones hide rows via a
DataFusion filter view). This completes the invariant: after compact,
tombstoned rows are PHYSICALLY absent from the parquet on disk.

delta::compact changes:
- Signature adds tombstones: &[Tombstone]
- After merging base + deltas, apply_tombstone_filter builds a
  BooleanArray keep-mask per batch (True where row_key_value is NOT
  in the tombstone set) and applies arrow::compute::filter_record_batch
- Supports Utf8, Int32, Int64 key columns (matches refresh.rs coverage
  for pg- and csv-derived schemas)
- CompactResult gains tombstones_applied + rows_dropped_by_tombstones
- Caller clears tombstone store on success

Critical correctness fix surfaced during E2E testing:
The original Phase 8 compact concatenated N independent Parquet byte
streams from record_batch_to_parquet() — each with its own footer.
Parquet readers only see the FIRST footer's data; the rest is invisible.
Latent since Phase 8 shipped; triggered by tombstone-filtering produc-
ing multiple batches. Corrupted candidates.parquet on first test run
(restored from UI fixture copy — good argument for test data in repo).

Fix:
- Single ArrowWriter per compaction, writes every batch into one
  properly-footered Parquet
- Snappy compression to match ingest defaults (otherwise rewrite
  inflated file 3× — 10.5MB → 34MB — because no compression was set)
- Verify-before-swap: parse written buf back to confirm row count
  matches expected; refuses to overwrite base_key if verification fails
- Write to {base_key}.compact-{ts}.tmp first, then to base_key; delete
  temp; only then delete delta files. Any error along the way leaves
  the original base intact.

TombstoneStore::clear(dataset) drops all tombstone batch files and
evicts the per-dataset AppendLog from cache. Called after successful
compact.

QueryEngine::catalog() accessor exposes the Registry so queryd
handlers can reach the tombstone store without routing through gateway
state.

E2E on candidates (100K rows, 15 cols):
- Baseline: 10.59 MB, 100000 rows
- Tombstone CAND-000001/2/3 (soft-delete): 99997 visible, 100000 raw
- Compact: tombstones_applied=3, rows_dropped=3, final_rows=99997
- Post: 10.72 MB (Snappy), valid parquet (1 row_group), 99997 rows
- Restart: persists, tombstones list empty, __raw__candidates also
  99997 (the 3 IDs are physically gone from disk)

PRD invariant close: deletion is now actually deletion, not just
masking. GDPR erasure request → tombstone + schedule compact → data
gone.

Deferred:
- Compact-all-datasets cron (currently manual per-dataset via
  POST /query/compact)
- Compaction of tombstone batch files themselves (they grow at
  flush_threshold=1 per tombstone; TombstoneStore::compact exists
  but not auto-called)

rootandClaude Opus 4.6 4d5c49090c Phase 16: Hot-swap generations + autotune agent loop 
Closes the self-iteration loop from the PRD reframe: an agent can
tune HNSW configs autonomously and the winner flows through to the
next profile activation without human intervention.

Three primitives:

1. PromotionRegistry (vectord::promotion)
   - Per-index current + history at _hnsw_promotions/{index}.json
   - promote(index, entry) atomically swaps current, pushes prior
     onto history (capped at 50)
   - rollback() pops history back onto current; clears current if
     history exhausted
   - config_or(index, default) — the read side used at build time,
     returns promoted config if set else caller's default
   - Full cache + persistence; writes are durable on return

2. Autotune (vectord::autotune)
   - run_autotune(request, ...) — synchronous agent loop
   - Default grid: 5 configs covering the practical range
     (ec=20/40/80/80/160, es=30/30/30/60/30) with seed=42 for
     reproducibility
   - Every trial goes through the existing trial-journal pipeline
     so autotune runs land alongside manual trials in the
     "trials are data" log
   - Winner: max recall first, then min p50 latency; must clear
     min_recall gate (default 0.9) or no promotion happens
   - Config bounds (ec ∈ [10,400], es ∈ [10,200]) reject absurd
     values from the request's optional custom grid
   - On winner: promote with note "autotune winner: recall=X p50=Y"

3. Wiring
   - VectorState gains promotion_registry
   - activate_profile now calls promotion_registry.config_or(...)
     so newly-promoted configs are picked up on next activation —
     the "hot-swap" is: autotune promotes -> profile activates ->
     HNSW rebuilt with new config
   - New endpoints:
       POST /vectors/hnsw/promote/{index}/{trial_id}
             ?promoted_by=...&note=...
       POST /vectors/hnsw/rollback/{index}
       GET  /vectors/hnsw/promoted/{index}
       POST /vectors/hnsw/autotune  { index_name, harness,
                                      min_recall?, grid? }

End-to-end verified on threat_intel_v1 (54 vectors):
- autogen harness 'threat_intel_smoke' (10 queries)
- POST /autotune -> 5 trials in 620ms, winner ec=20 es=30
  recall=1.00 p50=64us auto-promoted
- Manual promote of ec=80 es=30 -> history depth 1
- Rollback -> back to ec=20 es=30 autotune winner
- Second rollback -> current cleared
- Re-promote + restart -> persistence verified
- Profile activation after promotion logged:
  "building HNSW ef_construction=80 ef_search=30 seed=Some(42)"
  proving the hot-swap loop is closed.

Deferred:
- Bayesian optimization (random-grid is fine at this config-space size)
- Append-triggered autotune (Phase 17.5 — refresh OnAppend policy
  can schedule autotune after appending sufficient new rows)
- Concurrent autotune per index guard (JobTracker integration)

PRD invariants satisfied: invariant 8 (hot-swappable indexes) is now
real code — promote is atomic, rollback is always available, the
active generation is a persistent pointer not a runtime convention.

rootandClaude Opus 4.6 a293502265 Phase 17: Model profiles + scoped search — the LLM-brain keystone 
Implements PRD invariant 9 ("every reader gets its own profile") and
completes the multi-model substrate vision. Local models (or agents)
bind to a named set of datasets; activation pre-loads their vector
indexes into memory; search enforces scope.

Schema (shared::types):
- ModelProfile { id, ollama_name, description, bound_datasets,
                 hnsw_config, embed_model, created_at, created_by }
- ProfileHnswConfig mirrors vectord::trial::HnswConfig to avoid a
  cross-crate dep cycle. Default (ec=80, es=30) matches the Phase 15
  trial winner.
- bound_datasets can reference raw dataset names OR AiView names
  (both register as DataFusion tables with the same name, so mixing
  raw tables and PII-redacted views composes naturally)

Catalog (catalogd::registry):
- put_profile validates id is a slug (alphanumeric + -_ only) and
  every binding resolves to an existing dataset or view
- Persistence at _catalog/profiles/{id}.json, loaded on rebuild
- get_profile / list_profiles / delete_profile

HTTP endpoints:
- POST /catalog/profiles  (create/update)
- GET  /catalog/profiles  (list)
- GET/DELETE /catalog/profiles/{id}
- POST /vectors/profile/{id}/activate  (HNSW hot-load)
- POST /vectors/profile/{id}/search    (scope-enforced)

Activation (vectord::service::activate_profile):
- For each bound dataset, find vector indexes with matching source
- Pre-load embeddings into EmbeddingCache
- Build HNSW with profile's config
- Report warmed indexes + per-binding failures + duration
- Failures on individual bindings don't abort — "substrate keeps
  working" per ADR-017

Scoped search (vectord::service::profile_scoped_search):
- Look up profile, verify index.source ∈ profile.bound_datasets
- Returns 403 with allowed bindings list if out-of-scope
- Uses HNSW if index is warm, brute-force cosine otherwise (graceful
  degradation — no "must activate first" friction)

Bug fix surfaced during testing: vectord::refresh::try_update_index_meta
was a no-op for first-time indexes, so threat_intel_v1 and
kb_team_runs_v1 (both built via refresh after Phase C shipped) didn't
show up in the index registry. Now it auto-infers the source from the
index name convention (`{source}_vN`) and registers new metadata with
reasonable defaults.

End-to-end verified:
- Created security-analyst profile bound to [threat_intel]
- POST /vectors/profile/security-analyst/activate → warmed
  threat_intel_v1 (54 vectors) in 156ms, HNSW built
- Within-scope search: method=hnsw, returned relevant IP indicators
- Out-of-scope: tried to search resumes_100k_v2 (source=candidates)
  → 403 "profile 'security-analyst' is not bound to 'candidates' —
    allowed bindings: [\"threat_intel\"]"
- staffing-recruiter profile created bound to candidates + placements;
  search without activation fell through to brute_force (graceful)

Deferred (Phase 17 followups):
- VRAM-aware activation (unload-then-load via Ollama keep_alive=0)
  — Ollama already handles this; we don't need to reinvent
- Model-identity in audit trail — Phase 13 has role-based audit;
  adding model_id is ~20 LOC when we want it
- Profile bucket pre-load (profile:user bucket mount) — Phase 17.5

rootandClaude Opus 4.6 d87f2ccac6 Phase E: Soft deletes (tombstones) for compliance-grade row deletion 
Implements GDPR/CCPA-compatible row-level deletion without rewriting
the underlying Parquet. Tombstone markers live beside each dataset and
are applied at query time via a DataFusion view that excludes the
deleted row_key_values.

Schema (shared::types):
- Tombstone { dataset, row_key_column, row_key_value, deleted_at,
              actor, reason }
- All tombstones for a dataset must share one row_key_column —
  enforced at write so the query-time filter remains a single
  WHERE NOT IN (...) clause

Storage (catalogd::tombstones):
- Per-dataset AppendLog at _catalog/tombstones/{dataset}/
- flush_threshold=1 + explicit flush after every append — tombstones
  are high-value, low-frequency; durability on return is the contract
- Reuses storaged::append_log infra so compaction is already wired
  (POST .../tombstones/compact will work once we expose it)

Catalog (catalogd::registry):
- add_tombstone validates dataset exists + key column compatibility
- list_tombstones for the GET endpoint
- TombstoneStore exposed via Registry::tombstones() for queryd

HTTP (catalogd::service):
- POST /catalog/datasets/by-name/{name}/tombstone
    { row_key_column, row_key_values[], actor, reason }
  Returns rows_tombstoned count + per-value failure list (207 on
  partial success).
- GET same path lists active tombstones with full audit info.

Query layer (queryd::context):
- Snapshot tombstones-by-dataset before registering tables
- Tombstoned tables: raw goes to "__raw__{name}", public "{name}"
  becomes DataFusion view with
  SELECT * FROM "__raw__{name}" WHERE CAST(col AS VARCHAR) NOT IN (...)
- CAST AS VARCHAR handles both string and integer key columns
- Untombstoned tables register as before — zero overhead

End-to-end on candidates (100K rows):
- Pick CAND-000001/2/3 (Linda/Charles/Kimberly)
- POST tombstone -> rows_tombstoned: 3
- COUNT(*) drops 100000 -> 99997
- WHERE candidate_id IN (those 3) -> 0 rows
- candidates_safe view transitively excludes them
  (Linda+Denver: __raw__candidates=159, candidates_safe=158)
- Restart: COUNT still 99997, 3 tombstones reload from disk

Reversibility: tombstones are reversible deletes, not destruction.
Power users can still query "__raw__{name}" to see deleted rows.
Phase 13 access control is what stops a non-admin from accessing
__raw__* tables.

Limits / follow-up:
- Physical compaction not yet integrated — Phase 8's compact_files
  doesn't read tombstones during merge. Tombstoned rows are still
  on disk until that integration ships.
- Phase 9 journald event emission for tombstones not wired —
  tombstone records carry their own actor+reason+timestamp so the
  audit trail is intact, but cross-referencing with the mutation
  event log would help compliance reporting.

rootandClaude Opus 4.6 09fd446c8d Phase D: AI-safe views — capability-surface projections over base data 
Implements the llms3.com "AI-safe views" pattern: a named projection
that exposes only whitelisted columns, with optional row filter and
per-column redactions. AI agents (or Phase 13 roles) bind to the view;
they can never accidentally see PII even if they write raw SQL.

Schema (shared::types):
- AiView { name, base_dataset, columns: Vec<String>, row_filter,
           column_redactions: HashMap<String, Redaction>, ... }
- Redaction enum: Null | Hash | Mask { keep_prefix, keep_suffix }

Catalog (catalogd::registry):
- put_view validates base dataset exists + columns non-empty
- Persists JSON at _catalog/views/{name}.json (sanitized name)
- rebuild() loads views alongside dataset manifests on startup

Query layer (queryd::context):
- build_context registers every AiView as a DataFusion view object
- Constructed SELECT applies whitelist projection, WHERE filter, and
  redaction expressions per column
  - Mask: substr(prefix) + repeat('*', mid_len) + substr(suffix)
  - Hash: digest(value, 'sha256')
  - Null: CAST(NULL AS VARCHAR) AS col
- DataFusion handles JOINs/aggregates over the view natively — it's a
  real view, not a query rewrite

HTTP (catalogd::service):
- POST /catalog/views (create)
- GET  /catalog/views (list)
- GET  /catalog/views/{name} (full def)
- DELETE /catalog/views/{name}

End-to-end test on candidates (100K rows, 15 columns):

  candidates_safe view:
    columns: candidate_id, first_name, city, state, vertical,
             skills, years_experience, status
    row_filter: status != 'blocked'
    redaction: candidate_id mask(prefix=3, suffix=2)

  SELECT * FROM candidates_safe LIMIT 5
    -> 8 columns only, candidate_id shown as "CAN******01"
       (PII fields email/phone/last_name absent from result)

  SELECT email FROM candidates_safe
    -> fails (column not in projection)

  SELECT email FROM candidates
    -> succeeds (raw table still accessible by name —
       Phase 13 access control is the gate, not the view itself)

Survives restart — view definitions reload from object storage.

Limits / not in MVP:
- View CANNOT shadow base table by name (DataFusion treats them as
  separate identifiers; access control must restrict raw-table access)
- row_filter is treated as trusted SQL — operators must validate
  before persisting; only authenticated admin path should call put_view
- Redaction expressions assume column is castable to VARCHAR; numeric
  redactions could be misleading (a Hash on Int64 returns a hex string
  that won't equi-join with another hash on the same value type)

rootandClaude Opus 4.6 24f1249a62 Federation layer 2: header routing + cross-bucket SQL 
Three pieces of the multi-bucket federation made real:

1. Catalog migration (POST /catalog/migrate-buckets)
   - One-shot normalizer for ObjectRef.bucket field
   - Empty -> "primary"; legacy "data"/"local" -> "primary"
   - Idempotent; re-running on canonical state is no-op
   - Ran on existing catalog: 12 refs renamed from "data", 2 already
     "primary", all 14 now canonical

2. X-Lakehouse-Bucket header middleware on ingest
   - resolve_bucket() helper extracts header, returns
     (bucket_name, store) or 404 with valid bucket list
   - ingest_file and ingest_db_stream now route writes per-request
   - Defaults to "primary" when header absent
   - pipeline::ingest_file_to_bucket records the actual bucket on the
     ObjectRef so catalog stays the source of truth for "where does this
     data live"
   - Verified: ingest with X-Lakehouse-Bucket: testing lands in
     data/_testing/, ingest without header lands in data/, bad header
     returns 404 with hint

3. queryd registers every bucket with DataFusion
   - QueryEngine now holds Arc<BucketRegistry> instead of single store
   - build_context iterates all buckets, registers each as a separate
     ObjectStore under URL scheme "lakehouse-{bucket}://"
   - ListingTable URLs include the per-object bucket scheme so
     DataFusion routes scans automatically based on ObjectRef.bucket
   - Profile bucket names like "profile:user" sanitized to
     "lakehouse-profile-user" since URL host segments can't contain ":"
   - Tolerant of duplicate manifest entries (pre-existing
     pipeline::ingest_file behavior creates a fresh dataset id per
     ingest); duplicates skipped with debug log
   - Backward compat: legacy "lakehouse://data/" URL still registered
     pointing at primary

Success gate: cross-bucket CROSS JOIN
  SELECT p.name, p.role, a.species
  FROM people_test p          (bucket: testing)
  CROSS JOIN animals a        (bucket: primary)
  LIMIT 5
returns rows correctly. DataFusion routed each scan to its bucket's
ObjectStore based on the URL scheme.

No regressions: SELECT COUNT(*) FROM candidates still returns 100000
from the primary bucket.

Deferred to Phase 17:
- POST /profile/{user}/activate (HNSW hot-load on profile switch)
- vectord storage paths becoming bucket-scoped (trial journals,
  eval sets per-profile)

rootandClaude Opus 4.6 650f5e97b6 Fix chunker UTF-8 boundary panic (causes 120GB OOM in refresh path) 
The chunker's &text[start..end] slice could land inside a multi-byte
UTF-8 character (e.g. narrow no-break space \u{202f}, em-dashes, smart
quotes — universal in pg-imported editorial data). Rust panics on
non-boundary string slicing. In the refresh path that panic is caught
by tokio's task machinery but somehow causes linear memory growth at
~540MB/sec until OOM at 120GB+.

Root cause: chunk boundaries computed by byte arithmetic without
checking is_char_boundary(). The existing "look for last sentence / \n
/ space" logic finds ASCII-safe positions, but the *primary* `end`
calculation `(start + chunk_size).min(text.len())` lands wherever.

Fix:
- ceil_char_boundary(s, idx) — forward-scan to the nearest valid
  UTF-8 char boundary. Used at end, actual_end, and next_start.
- Iteration cap — break if iterations exceed text.len(). Any
  non-progressing loop dies safely instead of burning memory.
- Forced forward advance — if overlap + boundary math produce a
  next_start <= start, force +1 char to guarantee termination.

Reproduced on kb_team_runs (585 pg-imported prompts with editorial
unicode): previous run grew memory linearly to 124GB over 240s then
OOM-killed. Same request after fix: peaks at <100MB, completes in
~4m42s to produce 12,693 embeddings. /vectors/search returns
relevant results.

Regression tests added:
- handles_multibyte_utf8_at_chunk_boundary — exact \u{202f} repro
- no_infinite_loop_on_no_spaces — 5KB text, no whitespace
- no_infinite_loop_on_degenerate_params — chunk_size == overlap

Surfaced by Phase C, but pre-existed as a latent bug since Phase 7.
Any Ollama-targeted RAG corpus with non-ASCII content would have hit
this once it grew past ~13KB per document.

rootandClaude Opus 4.6 97a376482c Phase C: Decoupled embedding refresh 
Implements the llms3.com-inspired pattern: embeddings refresh
asynchronously, decoupled from transactional row writes. New rows arrive,
ingest marks the vector index stale, a later refresh embeds only the
delta (doc_ids not already in the index).

Schema additions (DatasetManifest):
- last_embedded_at: Option<DateTime> - when the index was last refreshed
- embedding_stale_since: Option<DateTime> - set when data written, cleared on refresh
- embedding_refresh_policy: Option<RefreshPolicy> - Manual | OnAppend | Scheduled

Ingest paths (pipeline::ingest_file + pg_stream) call
registry.mark_embeddings_stale after writing. No-op if the dataset has
never been embedded — stale semantics only kick in once last_embedded_at
is set.

Refresh pipeline (vectord::refresh::refresh_index):
- Reads the dataset Parquet, extracts (doc_id, text) pairs
- Accepts Utf8 / Int32 / Int64 id columns (covers both CSV and pg schemas)
- Loads existing embeddings via EmbeddingCache (empty on first-time build)
- Filters to rows whose doc_id is NOT in the existing set
- Chunks (chunker::chunk_column), embeds via Ollama (batches of 32),
  writes combined index, clears stale flag

Endpoints:
- POST /vectors/refresh/{dataset_name} - body {index_name, id_column,
  text_column, chunk_size?, overlap?}
- GET /vectors/stale - lists datasets whose embedding_stale_since is set

End-to-end verified on threat_intel (knowledge_base.threat_intel):
- Initial refresh: 20 rows -> 20 chunks -> embedded in 2.1s,
  last_embedded_at set
- Idempotent second refresh: 0 new docs -> 1.8ms (pure delta check)
- Re-ingest to 54 rows: mark_embeddings_stale fires -> stale_since set
- /vectors/stale surfaces threat_intel with timestamps + policy
- Delta refresh: 34 new docs embedded in 970ms (6x faster than full
  re-embed); stale_cleared = true

Not in MVP scope:
- UPDATE semantics (same doc_id, different content) - would need
  per-row content hashing
- OnAppend policy auto-trigger - just declares intent; actual scheduler
  deferred
- Scheduler runtime - the Scheduled(cron) variant declares the intent so
  operators can see which datasets expect what, but the cron itself is
  separate

Per ADR-019: when a profile switches to vector_backend=Lance, this
refresh path benefits — Lance's native append replaces our "read all +
rewrite" Parquet rebuild pattern. Current MVP works well enough at
~500-5K rows to validate the architecture; Lance unblocks the 5M+ case.

rootandClaude Opus 4.6 76f6fba5de Phase B: Lance pilot — hybrid decision with measured benchmark 
Standalone benchmark crate `crates/lance-bench` running Lance 4.0 against
our Parquet+HNSW at 100K × 768d (resumes_100k_v2) measured 8 dimensions.

Results (see docs/ADR-019-vector-storage.md for full scorecard):

  Cold load:        Parquet 0.17s   vs Lance 0.13s   (tie — not ≥2× threshold)
  Disk size:        330.3 MB        vs 330.4 MB      (tie)
  Search p50:       873us           vs 2229us        (Parquet 2.55× faster)
  Search p95:       1413us          vs 4998us        (Parquet 3.54× faster)
  Index build:      230s (ec=80)    vs 16s (IVF_PQ)  (Lance 14× faster)
  Random access:    35ms (scan)     vs 311us         (Lance 112× faster)
  Append 10K rows:  full rewrite    vs 0.08s/+31MB   (Lance structural win)

Decision (ADR-019): hybrid, not migrate-or-reject.

- Parquet+HNSW stays primary — our HNSW at ec=80 es=30 recall=1.00 is
  2.55× faster than Lance IVF_PQ at 100K in-RAM scale
- Lance joins as second backend per-profile for workloads where it wins
  architecturally: random row access (RAG text fetch), append-heavy
  pipelines (Phase C), hot-swap generations (Phase 16, 14× faster
  builds), and indexes past the ~5M RAM ceiling
- Phase 17 ModelProfile gets vector_backend: Parquet | Lance field
- Ceiling table in PRD updated — 5M ceiling now says "switch to Lance"
  instead of "migrate" since Lance runs alongside, not instead of

Isolation: lance-bench is a standalone workspace crate with its own dep
tree (Lance pulls DataFusion 52 + Arrow 57 incompatible with main stack
DataFusion 47 + Arrow 55). Kept off the critical path until API is
stable enough to promote into vectord::lance_store.

rootandClaude Opus 4.6 dbe00d018f Federation foundation + HNSW trial system + Postgres streaming + PRD reframe 
Four shipped features and a PRD realignment, all measured end-to-end:

HNSW trial system (Phase 15 horizon item → complete)
- vectord: EmbeddingCache, harness (eval sets + brute-force ground truth),
  TrialJournal, parameterized HnswConfig on build_index_with_config
- /vectors/hnsw/trial, /hnsw/trials/{idx}, /hnsw/trials/{idx}/best,
  /hnsw/evals/{name}/autogen, /hnsw/cache/stats
- Measured on resumes_100k_v2 (100K × 768d): brute-force 44ms -> HNSW 873us
  at 100% recall@10. ec=80 es=30 locked as HnswConfig::default()
- Lower ec values trade recall for build time: 20/30 = 0.96 recall in 8s,
  80/30 = 1.00 recall in 230s

Catalog manifest repair
- catalogd: resync_from_parquet reads parquet footers to restore row_count
  and columns on drifted manifests
- POST /catalog/datasets/{name}/resync + POST /catalog/resync-missing
- All 7 staffing tables recovered to PRD-matching 2,469,278 rows

Federation foundation (ADR-017)
- shared::secrets: SecretsProvider trait + FileSecretsProvider (reads
  /etc/lakehouse/secrets.toml, enforces 0600 perms)
- storaged::registry::BucketRegistry — multi-bucket resolution with
  rescue_bucket read fallback and reachability probing
- storaged::error_journal — bucket op failures visible in one HTTP call
- storaged::append_log — write-once batched append pattern (fixes the RMW
  anti-pattern llms3.com calls out; errors and trial journals both use it)
- /storage/buckets, /storage/errors, /storage/bucket-health,
  /storage/errors/{flush,compact}
- Bucket-aware I/O at /storage/buckets/{bucket}/objects/{*key} with
  X-Lakehouse-Rescue-Used observability headers on fallback

Postgres streaming ingest
- ingestd::pg_stream: DSN parser, batched ORDER BY + LIMIT/OFFSET pagination
  into ArrowWriter, lineage redacts password
- POST /ingest/db — verified against live knowledge_base.team_runs
  (586 rows × 13 cols, 6 batches, 196ms end-to-end)

PRD realignment (2026-04-16)
- Dual use case: staffing analytics + local LLM knowledge substrate
- Removed "multi-tenancy (single-owner system)" from non-goals
- Added invariants 8-11: indexes hot-swappable, per-reader profiles,
  trials-as-data, operational failures findable in one HTTP call
- New phases 16 (hot-swap generations), 17 (model profiles + dataset
  bindings), 18 (Lance vs Parquet+sidecar evaluation)
- Known ceilings table documents the 5M vector wall and escape hatches
- ADR-017 (federation), ADR-018 (append-log pattern) added
- EXECUTION_PLAN.md sequences phases B-E with success gates and
  decision rules

# PRD: Observer Knowledge Base
**Status:** Active — extraction pipeline proven, needs multi-pass processing via LLM Team modes
**Created:** 2026-03-28
**Owner:** J
**Branch:** `observer-kb`
**Parent:** Lakehouse core (crates/)
---
## Problem
AI conversations generate massive amounts of knowledge that's lost to context windows, hallucination, and scope drift. Current approach (single-pass extraction into categories) produces disorganized, hard-to-validate output. Reading raw pages is not useful — the system needs to process, clean, structure, and curate knowledge like an editorial team.
## Vision
A publishing pipeline that takes raw AI conversation exports and produces well-curated, validated knowledge documents. The output should be something you hand to a team — organized, filtered, and clearly presented. Questions anchor the content, with branching connections showing what was asked, what was answered, and how reasoning was directed.
---
## Architecture
### Multi-Pass Processing via LLM Team Modes
The key insight: devop.live already has 20 analysis modes that process content through structured workflows. The Observer KB should route uploaded data through these modes automatically.
```
Raw PDF Upload
│
▼ Mode: EXTRACT
Structured facts, entities, relationships
│
▼ Mode: VALIDATOR
Fact-check claims, score 1-10 confidence
│
▼ Mode: HALLUCINATION
Verify each claim, flag likely hallucinations
│
▼ Mode: CONSENSUS
Multiple passes iterate until extraction converges
│
▼ Mode: REDTEAM
Find flaws in knowledge, patch them
│
▼ Mode: PIPELINE (custom)
Clean → Q&A structure → topic grouping → value ranking
│
▼ RENDER
Well-curated document: questions as anchors, branching connections,
what was asked → answered → directed
```
### Integration with devop.live (LLM Team)
The Observer KB calls the LLM Team API to run modes against extracted content:
| Mode | Purpose in KB |
|---|---|
| **extract** | Structured facts, entities, relationships from raw text |
| **validator** | Fact-check extracted claims, confidence scores |
| **hallucination** | Verify each factual claim independently |
| **drift** | Process N times, find consistent vs uncertain content |
| **redteam** | Find flaws in extracted knowledge, improve |
| **consensus** | Iterate until multiple passes agree on correct extraction |
| **pipeline** | Chain: clean → extract → validate → organize → render |
| **research** | Generate follow-up questions, research in parallel |
| **blindassembly** | Split content into parts, process independently, reassemble |
### Data Flow
```

```
---
## Processing Pipeline Detail
### Pass 1: Clean + Structure
- Strip PDF artifacts (headers, footers, page numbers)
- Identify conversation turns (user/AI)
- Fix encoding issues (ligatures, special chars)
- Normalize formatting
### Pass 2: Q&A Extraction
- Identify questions asked by user
- Map each question to its answer
- Track follow-up questions and how they branch
- Build question→answer→follow-up chains
### Pass 3: Fact Extraction + Validation
- Run EXTRACT mode: pull structured facts, entities, relationships
- Run VALIDATOR mode: score each fact 1-10 confidence
- Run HALLUCINATION mode: verify claims independently
- Flag contradictions between conversations
### Pass 4: Organize + Curate
- Run CONSENSUS mode: multiple passes converge on correct categorization
- Auto-generate topic categories from content (not predefined)
- Rank content by value (decisions > insights > discussion > noise)
- Connect related content across conversations
### Pass 5: Render
- Question-anchored view: each question is a node, answers branch from it
- Topic-grouped view: knowledge organized by auto-generated categories
- Timeline view: how thinking evolved across conversations
- Export as clean markdown/PDF
---
## Current State (as of 2026-03-28)
### What's Built
- PDF ingestion (8 PDFs, 477 pages extracted)
- Single-pass knowledge extraction (496 topics, 300 decisions, 100 insights)
- Semantic search via HNSW (27ms over 477 chunks)
- RAG (question → search → LLM answer with sources)
- 5-pass deep analysis (corpus overview, patterns, evolution, gaps, synthesis)
- Observer KB web UI (knowledge-first, not page-first)
- Upload portal with drag & drop
### What's Not Built Yet
- Integration with devop.live LLM Team modes
- Multi-pass processing pipeline (extract → validate → hallucination check)
- Q&A chain extraction (question → answer → follow-up mapping)
- Contradiction detection between conversations
- Curated document export (PDF/markdown)
- Question-anchored navigation
- Auto-processing on upload (currently manual script)
### What Needs to Happen Next Session
1. **Integrate with devop.live API** — call modes programmatically
2. **Build the multi-pass pipeline** — extract → validate → hallucinate-check → organize
3. **Q&A chain extraction** — questions as anchors, answers branching
4. **Auto-process on upload** — no manual script, pipeline runs automatically
5. **Render curated output** — readable, hand-it-to-someone quality
---
## Tech Stack
- **Storage:** Lakehouse storaged (Parquet on object storage)
- **Catalog:** Lakehouse catalogd (metadata, PII, lineage)
- **Query:** Lakehouse queryd (DataFusion SQL, hot cache, paged results)
- **Vectors:** Lakehouse vectord (HNSW search, RAG)
- **AI Processing:** devop.live LLM Team API (20 modes, multiple models)
- **AI Runtime:** Ollama (local models — qwen2.5, mistral, gemma2, nomic-embed-text)
- **UI:** Pure HTML/JS on :3400
---
## Non-Goals (for now)
- Real-time conversation ingestion (PDF exports only)
- Multi-user collaboration
- Cloud deployment
- Editing extracted knowledge from UI (read-only for now)

//! Scheduled ingest — the production-substrate piece that turns the

//!
//! A `ScheduleDef` declares "what to ingest" + "when to fire." A
//! background `Scheduler` task wakes periodically, asks each enabled
//! schedule whether it's due, and runs the matching ingest path. Outcomes
//! land back on the schedule so operators can see what happened without
//! `journalctl` archaeology.
//!
//! Storage shape: one JSON file per schedule at
//! `primary://_schedules/{id}.json`. Serializable via serde, rebuilt on
//! startup. Same write-once shape as the rest of the catalog — no DB.
//!
//! Concurrency model: single-flight per schedule_id. The scheduler holds
//! a `HashSet<String>` of currently-running ids; a tick that finds a
//! schedule already in flight skips it (no queueing — a slow ingest
//! shouldn't pile up runs). Different schedules run concurrently.
//!
//! What's deliberately not in scope here:
//! - Cron expressions (the trigger enum has the variant but parsing is
//! stubbed). Intervals cover 90% of operational scheduling; cron is
//! easy to bolt on later.
//! - Backoff / retry policies. A failed run records the failure and
//! schedules `next_run_at` as if it succeeded — no exponential backoff.
//! - Distributed coordination. Single-machine scheduler; no leader
//! election. If you run two gateway instances they'll both fire.

//
// 1. SINCE LAST COMPLETION (current default below):
// next = completed_at + interval
// Easy to reason about. A long-running ingest delays the next fire
// by however long it took. Drift is bounded — the schedule never
// "falls behind" trying to catch up.
//
// 2. ANCHORED INTERVAL:
// next = previous_target + interval, regardless of when run finished
// Keeps wall-clock alignment ("every 30min on the :00 and :30").
// Risk: if ingest takes longer than the interval, the next run is
// "due immediately" and you can fire back-to-back forever.
//
// 3. ANCHORED + SKIP:
// Anchored, but skip a tick if the previous one is still running.
// Best of both, slightly more code.
//
// 4. CRON:
// Parse the expression, find the next match after `now`. Most

//! Phase B: Lance pilot benchmark.
//!
//! Standalone binary that compares Lance vector storage against our
//! Parquet-with-binary-blob + in-RAM HNSW approach. See
//! docs/EXECUTION_PLAN.md for the decision rules this fuels.
//!
//! Inputs:
//! data/vectors/resumes_100k_v2.parquet — existing 100K × 768d embeddings
//!
//! Output:
//! A JSON report printed to stdout with measurements for:
//! - Cold load time (parquet → arrow) vs Lance open + scan
//! - Disk size
//! - Vector search latency (p50 / p95 / p99)
//! - Single-row random access
//! - Append cost (adding 10K rows)
//!
//! Usage:
//! cargo run --bin lance-bench -- \
//! --parquet data/vectors/resumes_100k_v2.parquet \
//! --lance-out /tmp/lance_resumes_100k_v2 \
//! --json-out /tmp/lance_bench.json

//! Production Lance vector backend (ADR-019 — hybrid architecture).
//!
//! This is the firewall crate. It owns its own Arrow 57 / DataFusion 52
//! / Lance 4 dependency tree. The public API uses only std types
//! (`Vec<f32>`, `Vec<String>`, `String`, `bool`) so nothing Arrow-shaped
//! crosses the crate boundary. That keeps vectord (Arrow 55) from
//! picking up an incompatible dep.
//!
//! Responsibilities:
//! - Migrate an existing binary-blob Parquet vector file into a Lance
//! dataset with `FixedSizeList<Float32, dims>`. One-time cost.
//! - Append new rows natively (no full-file rewrite — Lance's structural win).
//! - Build an IVF_PQ ANN index on the vector column.
//! - Vector search (`search`) using the IVF_PQ index when present,
//! falling back to full scan otherwise.
//! - Random-access row fetch by `doc_id` (`get_by_doc_id`) — the O(1)
//! lookup that Parquet-on-object-store can't cheaply do.
//! - Cheap count + stats introspection.

//! Phase 16.2 + 16.5 — The autotune agent.
//!
//! A long-running tokio task that watches the trial journal and
//! autonomously proposes + runs new HNSW configs. Distinct from
//! `autotune::run_autotune` which is synchronous (one HTTP call, grid
//! of trials, done). The agent is the continuous version: it sleeps,
//! wakes on triggers, proposes configs based on prior trial history,
//! runs them one at a time, and auto-promotes when it finds an
//! improvement.
//!
//! Design invariants:
//! - Trials are data (ADR-018). Every proposal reads the journal; every
//! attempt appends to it. The journal is the agent's memory.
//! - One trial at a time. Bounded Ollama load — the agent never fires
//! multiple parallel embeddings and respects `cooldown_between_trials_secs`.
//! - Rate-limited. `max_trials_per_hour` is a hard ceiling so a
//! misbehaving proposal function can't saturate the system.
//! - Never promotes below `min_recall`. Same safety gate as
//! `run_autotune` — we will not make the index worse.
//! - Triggered OR periodic. Ingest enqueues a `DatasetAppended` event
//! when a new batch lands; the agent also wakes periodically to keep
//! exploring even when nothing changed externally.
//! - Graceful shutdown via the `stop_tx` signal — the handle's Drop
//! doesn't force-kill, but `stop()` requests a clean exit after the
//! current trial.

//! Phase 16: Autotune — the agent loop for HNSW tuning.
//!
//! Given an index and a harness, run a grid of (ef_construction,
//! ef_search) trials, pick the Pareto winner, and promote it.
//!
//! This is deliberately NOT a sophisticated optimizer — random-grid
//! search is good enough when the config space is small (a dozen
//! combinations) and the work per trial is seconds, not hours. Think
//! of it as a "smart operator" rather than Bayesian optimization.
//!
//! Score: we want high recall and low p50 latency. The function below
//! picks the Pareto-dominating trial, breaking ties by prefer-lower-
//! build-time (cheaper to rebuild on data changes).
//!
//! Safeguards (PRD risk mitigation):
//! - Never promote a trial with recall < `min_recall` (default 0.9)
//! - Hard config bounds: ef_construction ∈ [10, 400], ef_search ∈ [10, 200]
//! - Concurrency cap: one autotune per index at a time (tracked by
//! JobTracker — caller is responsible for not firing in parallel
//! for the same index)

//! Phase 16: Promoted HNSW configs — the "active generation" pointer.
//!
//! An index's HNSW config used at build time normally defaults to the
//! system-wide default (`HnswConfig::default()`). An operator or the
//! autotune agent can *promote* a specific trial's config — subsequent
//! HNSW builds against that index use the promoted config instead.
//!
//! Every promotion is history-tracked so `rollback` can revert. The
//! history file lives at `primary://_hnsw_promotions/{index_name}.json`
//! and is small (< few KB) so we rewrite it on every promotion rather
//! than append-log.
//!
//! Not included here:
//! - Atomic graph rebuild on promote — promotion only updates the sticky
//! default. Next activation (or search that triggers lazy build) picks
//! up the new config. That's "zero-downtime swap after build" which is
//! what ADR-019 actually claimed; an instant-swap requires a
//! pre-built graph pool which we don't have yet.
//! - Agent loop — lives in `vectord::autotune`.

//! Phase C: Decoupled embedding refresh.
//!
//! When a dataset's row-level data changes, the vector index it feeds is
//! stale. Historically we coupled ingest and embedding — writing new rows
//! also re-embedded every row, which is fine at 500 rows but blows up at
//! 100K+. The llms3.com architecture calls out "asynchronous vector
//! refresh cycles independent from transactional mutations" as the right
//! pattern.
//!
//! This module implements the refresh side. The ingest path marks
//! embeddings stale (see catalogd::registry::mark_embeddings_stale); this
//! code clears that staleness by embedding only rows whose `doc_id` isn't
//! already in the existing vector index.
//!
//! Scope — MVP:
//! - Reads the dataset's Parquet, extracts (doc_id, text) pairs from named
//! columns
//! - Loads existing embeddings via EmbeddingCache
//! - Filters to rows whose doc_id is NOT in the existing set
//! - Chunks, embeds via Ollama, appends to the index parquet
//! - Clears stale flag on success
//!
//! Not in MVP:
//! - UPDATE semantics (same doc_id, new content) — would need content-hash
//! comparison per row
//! - Large-scale resilience (batching with checkpoints like the
//! supervisor) — MVP does it inline
//! - Lance backend — ADR-019 makes this straightforward later; MVP stays
//! on Parquet sidecar indexes
