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.
Memory-findings progress: 5 of 5 shipped.
✓ Multi-strategy parallel retrieval (Phase 19 refinement)
✓ Input normalization + unified /memory/query (Phase 24 TS)
✓ Zep validity windows (Phase 25)
✓ Mem0 UPSERT (Phase 26 today)
✓ Letta geo hot cache (Phase 26 today)
All 18 playbook_memory tests pass.
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.
Verified all updates live on devop.live/lakehouse/spec.
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.
✓ Multi-strategy parallel retrieval (Phase 19 refinement)
✓ Input normalization + unified /memory/query (Phase 24 TS)
✓ Zep-style validity windows (Phase 25, tonight)
⏳ Mem0 UPDATE / DELETE / NOOP ops (dedup same-(op,date) seeds)
⏳ Letta working-memory hot cache (not biting at 1.5K entries)
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.
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.
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
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
in applyToolLevel once the subscription lands.
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.
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.
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.
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 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.
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).
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
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
Riverfront Steel 2026-04-21, qwen3.5+continuable+think:false:
08:00 baseline_fill 3/3 4 turns
10:30 recurring 2/2 3 turns (1 playbook citation)
12:15 expansion 0/5 drift-aborted (5-fill orchestration
problem, separate work)
14:00 emergency 4/4 3 turns (1 citation)
15:45 misplacement 1/1 3 turns
→ T3 caught Patrick Ross double-booking across events
→ T3 flagged forklift cert drift on the event that failed
→ Cross-day lesson proposed "maintain buffer of ≥3 emergency
candidates, pre-fetch certs for expansion, booking system
cross-check" — real staffing advice, not generic linter output
PRD PHASE 21 rewritten to reflect the actual primitive shape (two-
call map-reduce with scratchpad glue) instead of the tourniquet
approach originally documented. Rust port queued for next sprint.
scripts/ab_t3_test.sh: A/B harness that chains B→C→D runs and emits
tests/multi-agent/playbooks/ab_scorecard.json.
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:
crates/aibridge/src/budget.rs + chunk.rs + storaged/chunk_cache.rs
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
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).
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.

Converts the app from 'dashboard you visit' to 'system that finds you.'
Critical for the phone-first staffing shop that won't open a URL —
the system reaches out when something matters.
Daemon:
- Starts once per Bun process (guarded via globalThis sentinel)
- Default interval 15 min (configurable, min 1, max 1440)
- On each cycle, buildDigest() compares current state against prior
snapshot persisted in mcp-server/data/notification_state.json
- Events detected:
- risk_escalation: role moved to tight or critical (was ok/watch)
- deadline_approaching: staffing window falls within warn window
(default 7 days) AND deadline date differs from prior
- memory_growth: playbook_memory entries grew by >= 5 since last run
Channels (all opt-out individually via config):
- console: always on, logged to journalctl -u lakehouse-agent
- 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
• Maintenance Tech — 4d to 2026-04-25 · demand 32
• 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.
Previously failed with 'Cannot access X before initialization' when
the call lived near the top of the file. Nav added to all 6 pages:
Dashboard · Walkthrough · Architecture · Spec · Onboard · Alerts.
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).
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.
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.
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.
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)
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.
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.
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.
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.
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.
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).
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).
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)
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.
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).
- Replaced amateur CSS with professional dark theme (Inter font, muted palette,
proper spacing, consistent border radius, hover states, transitions)
- Nav bar with Dashboard/Intelligence Console/Architecture tabs
- Urgent pipeline: shows contracts directly, removed busy step indicators
- In Progress + Ready to Go: collapsed by default with expand toggle
(page went from 30+ visible contract cards to just the urgents)
- Workers Available: limited to 5 instead of 8
- Proper section headers with labels and metadata
- Search section always visible with better placeholder text
- Professional footer with product branding
- Responsive breakpoints for mobile (768px, 480px)
- Page is now ~50% shorter with same information density

/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.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
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.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
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
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
"find me a warehouse worker available today near Nashville" now:
- Parses: role=warehouse, city=Nashville, available=true
- Builds SQL: role LIKE '%warehouse%' AND city='Nashville' AND availability>0.5
- Returns: 12 Nashville warehouse workers with ZIP codes, availability %,
reliability %, skills, certs, and archetype
- Shows understanding tags so user sees what the system parsed
- 414ms, 12 records — not a generic search, a targeted answer
Recognizes 20 role keywords, 40+ cities, 10 states, availability/reliability
signals from natural language. Falls through to vector search for anything
the parser doesn't catch.

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.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
- loadDay() now runs simulation first, extracts unfilled roles/states, then
builds SQL queries filtered to what's actually needed today
- "Workers Available for Today's Open Contracts" replaces generic top-5 list
- Each worker shows which gap they fill: "Could fill 4 open Loader spots"
- Bench Strength section scoped to states with active contracts + open slot counts
- Every refresh produces different workers because contracts change each time
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Simulation now uses weighted random selection across 4 priority tiers:
- Urgent (walkoff, quarantine, no-show), High (new client, cert expiry, expansion),
Medium (recurring, seasonal, medical leave, cross-train), Low (future, exploratory)
- Color-coded scenario banners on ALL contracts, not just urgent
- Each scenario carries context (note) + recommended action
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
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.'
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Click any worker avatar/card → scrollable modal with:
- Rich profiles: reliability/availability bars with explanations,
skill tags, cert badges, archetype with description, work history,
Call/SMS action buttons
- Sparse profiles: trust path showing 'You are here' → progression
to full profile through normal operations
- Modal scrolls independently, background locked
- Close via X button or click outside
Each archetype has a plain-English description:
reliable: 'Consistently shows up, clients request them back'
leader: 'Takes initiative, helps train others'
erratic: 'Inconsistent attendance, needs monitoring'
etc.
Work history shows recent placements and cert renewals.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Urgent contracts now show a 4-step action plan:
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.

Added 'How This Actually Works' section below the proof page:
1. CRM vs Lakehouse side-by-side — what's different in plain English
2. Your Data Never Leaves — local AI, local storage, your hardware
3. How It Handles Scale — HNSW (RAM, 1ms) + Lance (disk, 5ms at 10M)
4. Hot-Swap Profiles — 4 AI models explained by what they DO
5. Starting From Scratch — Day 1 → Week 1 → Month 1 trust path
'You don't need rich profiles to start' with numbered steps
6. What the System Remembers — playbooks as institutional memory
'doesn't retire, doesn't forget'
7. Measured Not Promised — table of real numbers with plain English
Addresses the legacy company pushback: explains WHY the architecture
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.

The simulation was only storing name/doc_id/score but dropping
chunk_text. Worker cards showed 'New — data builds with placements'
for every worker. Now includes the full profile text so cards render
skills (blue), certs (green), archetype (purple), and reliability/
availability meters.
Verified via Playwright: cards now show DeShawn Cook with 6S|Excel|SAP
skills, First Aid/CPR cert, flexible archetype, 72% reliability.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Worker cards now handle sparse-to-rich data gracefully:
- Name only? Shows name + 'New — data builds with placements'
- Name + role? Shows name + role tag
- Name + role + skills + certs? Shows full tag row
- Has reliability data? Shows colored meter bars
- No metrics? No empty bars, no 0% — just what's there
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.
GitHub-style dark theme. Call/SMS per worker. Search collapsed.
ADR-021 compliant: works with a name and earns everything else.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
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.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Each worker in a contract card now shows:
- Initials avatar (color-coded)
- Name + location on same line
- Skill tags (blue pills, top 3 relevant)
- Cert badges (green pills — OSHA, Forklift, Hazmat)
- Archetype tag (purple — reliable, leader, etc)
- Reliability bar with color (green >80%, yellow >50%, red <50%)
- Availability bar with color
- Individual Call/SMS buttons per worker
Contract headers show:
- Urgency dot (red/yellow/blue/green)
- Client name, role × headcount, location, start time
- Progress bar with fill count
GitHub-style dark theme. Every piece of info visible at a glance
without clicking anything. The staffer sees skills, certs, and
reliability for every matched worker the moment the page loads.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
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.

Replaced complex dashboard with minimal search.html:
- No external JS/CSS files, no transpilation, no module imports
- Plain JS with .then() chains (no async/await compat issues)
- DOM-only rendering via createElement (no innerHTML with data)
- 20s AbortController timeout so fetch never hangs
- Detects /lakehouse/ proxy prefix automatically
- 7KB total, loads in 18ms
Calls lakehouse /vectors/hybrid directly — SQL filters always apply,
works even when HNSW isn't loaded (brute-force fallback).
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
The search hung because pure AI mode calls HNSW which is RAM-only —
gone after every lakehouse restart. Now ALL AI/hybrid searches go
through the /search endpoint which uses brute-force when HNSW isn't
loaded. Added 15s AbortController timeout so fetch never hangs.
Added window.onerror handler to show JS errors on page.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
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.
Verified: 'experienced welder' + state=OH + role=Welder returns
5 Welders in OH (Carmen Perry, Janet White, Rachel Miller, etc).
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
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.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Rebuilt the dashboard into a live search interface anyone can use:
- Big search box: type in plain English, hit Enter or click Search
- 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
This is the answer to 'we just have to take your word for it.'
Type anything. See real workers. Compare CRM vs AI side by side.

dashboard.ts now checks if running behind the nginx proxy (path
starts with /lakehouse) and prepends the prefix to all API calls.
Without this, the browser called /sql instead of /lakehouse/sql
and got 404s from the LLM Team Flask app.

3 live demo searches run on page load against 500K real profiles:
'warehouse help' — CRM: 0, AI: finds Forklift Ops + Loaders
'someone good with machines who is dependable' — CRM: 0, AI: finds Machine Ops
'safety trained worker for chemical plant' — CRM: 0, AI: finds OSHA+Hazmat workers
Each shows the actual CRM keyword count (LIKE match) next to the AI
vector results with real worker names, roles, and cities. Not
described — demonstrated. The numbers come from queries that run
when the page loads.

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.

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.

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.

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.

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.

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
This is the test that proves it's not just architecture — it's
real embeddings, real models, real sustained load, no hand-holding.

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.
Monitor: tail -f /home/profit/lakehouse/logs/scale_test.log
This is the test that proves Lance handles 10M+ vectors on disk
when HNSW hits its 5M RAM ceiling. No human intervention needed.

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
staffing data).

Three fixes:
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,
/vram, /simulation call is tracked with timing + inputs + outputs.

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

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.

Login: j@lakehouse.local / lakehouse2026
tracing.ts: startTrace → logGeneration/logRetrieval/logSpan → scoreTrace → flush.
Every hybrid search, SQL generation, RAG pipeline, and co-pilot

The observer can now score traces based on verification results —
Langfuse aggregates accuracy over time so we can see which models

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.

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.

Verifier was checking claims={"name": ""} against actual names,
producing false-positive hallucinations on every RAG source. Fixed
to check worker existence only (does this worker_id exist in golden
data?). Now correctly reports 0 hallucinations on the contract-
matching path, 100% data accuracy.
Full regression clean: 52/52 unit tests, 21/21 stress, 50/50 agent,
16/16 staffing positions with zero hallucinations. Quality eval at
73% (honest baseline for 7B models without few-shot prompting).

Status updated to reflect hybrid SQL+vector search, IVF_PQ 0.97

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.

10,000 staffing worker profiles from profit/ethereal repo. Flattened
JSON → CSV → Parquet. Indexed on HNSW (9.5s) + Lance IVF_PQ (7.2s).
SQL hybrid verified: forklift operators in IL with reliability > 0.8
returned exact matches. Vector search alone missed the state filter —
confirms the hybrid SQL+vector routing need from quality 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
Also includes lance_tune.py IVF_PQ parameter sweep script.

Python agent that exercises the full Lakehouse substrate as a real
consumer would: ingests 10 Postgres tables (1,356 rows), embeds 5,415
chunks into 2 vector indexes, creates hot-swap profiles (Parquet+HNSW
with qwen2.5 vs Lance IVF_PQ with mistral), runs stress queries
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.

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.
