G1P: vectord persistence to storaged + scrum (3 fixes incl. 3-way convergent)
Adds optional persistence to vectord (G1's HNSW vector search). Single-
file framed format per index — eliminates the torn-write class that
the 3-way convergent scrum finding identified:
_vectors/<name>.lhv1 — single binary blob:
[4 bytes magic "LHV1"]
[4 bytes envelope_len uint32 BE]
[envelope bytes — JSON params + metadata + version]
[graph bytes — raw hnsw.Graph.Export]
Pre-extraction: internal/catalogd/store_client.go → internal/storeclient/
shared package, since both catalogd and vectord need it. Same pattern as
the pre-D5 catalogclient extraction.
Optional via [vectord].storaged_url config (empty = ephemeral mode).
On startup: List + Load each persisted index. After Create / batch Add /
DELETE: Save (or Delete from storaged). Save failures are logged-not-
fatal — in-memory state is the source of truth in flight.
Acceptance smoke G1P 8/8 PASS — kill+restart preserves state, post-
restart search returns dist=0 (graph round-trips exactly), DELETE
removes the file, post-delete restart shows count=0.
All 8 smokes (D1-D6 + G1 + G1P) PASS deterministically. The g1_smoke
gained scripts/g1_smoke.toml that disables persistence so the
in-memory API test stays decoupled from any rehydrate-from-storaged
state contamination.
Cross-lineage scrum on shipped code:
- Opus 4.7 (opencode): 1 BLOCK + 5 WARN + 3 INFO
- Kimi K2-0905 (openrouter): 1 BLOCK + 2 WARN
- Qwen3-coder (openrouter): 2 BLOCK + 2 WARN + 1 INFO
Fixed (3 — 1 convergent + 2 single-reviewer):
C1 (Opus + Kimi + Qwen 3-WAY CONVERGENT WARN): Save was non-atomic
across two PUTs — envelope-succeeds + graph-fails left a half-
saved index that passed the "both present" List filter and
silently mismatched metadata against vectors on Load.
Fix: collapse to single framed file (no torn-write window
possible).
O-B1 (Opus BLOCK): isNotFound substring-matched "key not found"
against the wrapped error message — brittle, any 5xx body
containing that text would silently misclassify as missing.
Fix: errors.Is(err, storeclient.ErrKeyNotFound).
O-I3 (Opus INFO): handleAdd pre-validation only covered id+dim;
NaN/Inf/zero-norm could still fail mid-batch leaving partial
commits. Fix: extend pre-validation to call ValidateVector
(newly exported) per item before any commit.
Dismissed (3 false positives):
K-B1 + Q-B1 ("safeKey double-escapes %2F segments") — false
convergent. Wire-protocol escape is decoded by storaged's chi
router on the way in; on-disk key is the original literal.
%2F round-trips correctly through PathEscape → URL → chi decode
→ S3 key.
Q-B2 ("List vulnerable to race conditions") — vectord is single-
process; no concurrent Save against List in the same vectord.
Deferred (3): rehydrate per-index timeout (G2+ multi-index scale),
saveAfter request ctx (matches G0 timeout deferral), Encode RLock
during slow writer (documented as buffer-only API).
The C1 finding is the strongest signal of the cross-lineage filter:
three independent reviewers all flagged the same torn-write hazard.
Single-file framing eliminates the class — there's now no Persistor
state where envelope and graph can disagree.

G0 D3: catalogd Parquet manifests + ADR-020 idempotent register · 6 scrum fixes
Phase G0 Day 3 ships catalogd: Arrow Parquet manifest codec, in-memory registry with the ADR-020 idempotency contract (same name+fingerprint reuses dataset_id; different fingerprint → 409 Conflict), HTTP client to storaged for persistence, and rehydration on startup. Acceptance smoke 6/6 PASSES end-to-end including rehydrate-across-restart — the load-bearing test that the catalog/storaged service split actually preserves state. dataset_id derivation diverges from Rust: UUIDv5(namespace, name) instead of v4 surrogate. Same name on any box generates the same dataset_id; rehydrate after disk loss converges to the same identity rather than silently re-issuing. Namespace pinned at a8f3c1d2-4e5b-5a6c-9d8e-7f0a1b2c3d4e — every dataset_id ever issued depends on these bytes.
