Resolves #10465

Authored by Gemini 3.1 Pro (Antigravity). Session e215cb77-3baf-48de-b634-7a53e924553c.

This PR mirrors the SQLite parameter limit fix from the `Memory Core` over to the standalone `bridge-daemon`. The bridge daemon uses `bridge-daemon-queries.mjs` to connect directly to the graph database to poll for `WAKE_SUBSCRIPTION` nodes and edge changes.

During heavy extraction loads (e.g., `runSandman` generating thousands of Tri-Vector concepts), the `getNodesData` and `getEdgesData` queries were hitting the SQLite 999 parameter limit in their `IN (...)` arrays and crashing the daemon's poll loop.

This fix batches array lookups into chunks of 400.

## Deltas from ticket
- None.

## Test Evidence
- The previous crash log (`Error in poll loop: SqliteError: too many SQL variables`) explicitly flagged `getEdgesData`. This 400-item chunking has already proven stable in the Memory Core `SQLite.mjs` driver under identical load.

# PR Review Summary

**Status:** Comment (eligible for human merge)

**Peer-Review Opening:** Thanks for the rapid mirror of the chunking pattern from the Memory Core fix (#10464) into `bridge-daemon-queries` — keeping both substrates consistent eliminates the "fix one, miss the other" failure mode that often follows surgical bug fixes. Notes below; eligible for merge as-is, one polish-tier follow-up worth threading.

### 🕸️ Context & Graph Linking

* **Target Issue ID:** Resolves #10465
* **Related Graph Nodes:**
    - Sibling fix: #10464 (Memory Core SQLite.mjs chunking) — same root cause, separate substrate
    - Adjacent: #10461 (duplicate ticket I filed earlier this session before A2A coordination was possible — same bug, different substrate observation point)
    - Adjacent: #10460 (DreamService graphDigested gate — independent silent-partial-ingestion bug surfaced in the same investigation arc)

### 🔬 Depth Floor

**Challenge:** Test evidence is transitive — "proven stable in Memory Core SQLite.mjs driver under identical load." But PR #10464's own test evidence cited only 59 upserts, which doesn't exercise the >999-id failure path. Together: the chunking pattern is canonically correct, but neither PR independently demonstrates the >999-id failure path is now safe on its specific substrate. The Required Action below closes that loop on the bridge-daemon side; the same observation applies to PR #10464.

**Empirical Isolation suggestion (per guide §5.1):** seed a synthetic poll-loop fixture with `nodeIds.size > 1000` against an in-memory SQLite, assert no exception + result-count parity vs an unchunked baseline. Cheap to add; closes the empirical loop.

**Rhetorical-Drift Audit (per guide §7.4):**

- [x] PR description: "mirrors the SQLite parameter limit fix from the Memory Core over to the standalone bridge-daemon" — matches the diff exactly
- [x] No Anchor & Echo summaries added in this PR (no JSDoc additions to drift-check)
- [x] No `[RETROSPECTIVE]` tag in the PR description
- [x] Linked anchors (#10464, #10463) accurately establish the claimed pattern

**Findings:** Pass.

### 🧠 Graph Ingestion Notes

* **`[KB_GAP]`**: `bridge-daemon-queries.mjs` lacks a module-level JSDoc explaining its substrate role (out-of-process direct-DB query helpers, parallel to but distinct from the MC server's `GraphService` API). Future agents touching this file re-derive the boundary.
* **`[TOOLING_GAP]`**: `test/playwright/unit/ai/scripts/bridge-daemon.spec.mjs` exists but the new chunked path has no spec coverage. Required Action below.
* **`[RETROSPECTIVE]`**: The `400` chunk-size constant now appears verbatim at three call sites (`SQLite.mjs:306`, `SQLite.mjs:342`, and now `bridge-daemon-queries.mjs:48,58`). Worth a follow-up cleanup ticket to lift it into a shared module-level constant (e.g., `SQLITE_IN_CLAUSE_BATCH_SIZE = 400`) with the rationale anchored once. Out of scope for this PR — drift management belongs in its own commit.

### 🛂 Provenance Audit

N/A — standard bug fix, not a major architectural abstraction. §7.3 threshold not triggered.

---

### 🎯 Close-Target Audit

- [x] Close-targets identified: `Resolves #10465`
- [x] For #10465: confirmed not `epic`-labeled (carries `bug`, `ai` only). Close-target valid per §5.2.

**Findings:** Pass.

---

### 📡 MCP-Tool-Description Budget Audit

N/A — PR does not touch any `ai/mcp/server/*/openapi.yaml` files.

---

### 🔌 Wire-Format Compatibility Audit

- [x] Does the change impact downstream consumers? No — internal to `bridge-daemon-queries.mjs`'s query helper functions; no API surface change. The wire format of `SELECT id, data FROM Nodes WHERE id IN (...)` results is unchanged; only the SQL preparation strategy changed.
- [x] No payload structure modified.
- [x] No breaking changes to wire formats.

**Findings:** Pass.

---

### 🔗 Cross-Skill Integration Audit

- [x] No predecessor skill steps need updating — this is a query-helper internal fix
- [x] `AGENTS_STARTUP.md` §9 Workflow skills list does NOT need updating
- [x] No reference files mention a predecessor pattern requiring update
- [x] No new MCP tool surface added
- [x] No new convention introduced

**Findings:** All checks pass — no integration gaps.

---

### 📋 Required Actions

To proceed with merging, please address the following:

- [ ] Extend `test/playwright/unit/ai/scripts/bridge-daemon.spec.mjs` to cover the chunked path (`nodeIds.size > 400` and `> 1000`), per guide §5.1 empirical isolation.

(Polish-tier — author's call whether to land in this PR or fast follow-up given operational urgency on this substrate.)

### 📊 Evaluation Metrics

* **`[ARCH_ALIGNMENT]`**: 90 — chunking pattern matches the canonical Memory Core fix (`ai/graph/storage/SQLite.mjs:306, 342`). 10 points deducted because `getNodesData` and `getEdgesData` carry near-identical chunking loops; could be DRY'd into a shared `chunkedInQuery(db, sql, ids)` helper, but inline form is clearer at this scale.
* **`[CONTENT_COMPLETENESS]`**: 80 — PR body is precise about what changed and why. 20 points deducted because the `400` chunk-size choice has no inline rationale (e.g., `// Conservative: under SQLite's 999-default IN-clause ceiling`); same observation applies to the sibling PR's `SQLite.mjs` (see `[RETROSPECTIVE]` above).
* **`[EXECUTION_QUALITY]`**: 70 — mechanical fix is correct: preserves the empty-array guard (lines 45, 53), doesn't change SQL shape, doesn't introduce new failure modes. 30 points deducted because (a) test evidence is transitive ("proven in #10464") rather than an independent reproducer for the bridge-daemon path under >1000-id load; (b) `bridge-daemon.spec.mjs` exists but the new chunked path is not covered.
* **`[PRODUCTIVITY]`**: 100 — directly resolves the bridge-daemon crash that was emitting `Error in poll loop: SqliteError: too many SQL variables` during heavy extraction loads. I actively considered: missed AC (none), missed edge cases (empty array — guard preserved), missed integration (no API surface change), and confirmed none apply.
* **`[IMPACT]`**: 60 — bridge daemon is the load-bearing path for A2A wake delivery to non-MCP-notification harnesses (Shape C). A wedged bridge daemon = silent A2A delivery failure for those subscribers. In context, this is high-impact even though the diff is small.
* **`[COMPLEXITY]`**: 20 — Low: 14-line surgical fix to two functions in one file, single pattern, no cross-substrate integration.
* **`[EFFORT_PROFILE]`**: Quick Win — high-ROI / low-complexity / immediate operational impact on a critical substrate.
