# KB Ingestion Phase 4: Operations + Observability for Cloud-Native Deployments

## Context

Phase 4 sub-Epic of meta-Epic [#11624](https://github.com/neomjs/neo/issues/11624) (Cloud-Native KB Ingestion for External Workspaces). NOT originally in Discussion [#11623](https://github.com/neomjs/neo/discussions/11623); surfaced 2026-05-19 during post-graduation operator-directed sub-decomposition review. Operator-mention of "daemons etc." prompted explicit operational-substrate decomposition.

**Blocked-by Phase 2 [#11626](https://github.com/neomjs/neo/issues/11626)** — most observability/reconciliation work needs the ingestion service + facades stable. Operator alerting + dashboard surfacing may begin in parallel once Phase 0/1 [#11625](https://github.com/neomjs/neo/issues/11625) contracts land (daemon-scaffolding can start pre-Phase-2).

## The Problem

Phase 2 ships the push pipeline; Phase 3 ships the operator-facing guide. What's missing for **production cloud Agent OS deployments**:

- No per-tenant ingestion observability (push frequency, error rates, ingestion latency, embedding-budget burn)
- No periodic state-reconciliation (catches missed tombstones; force-push detection beyond per-push payload)
- No stale-chunk garbage collection (orphans from source removal, parser swap, retention policy)
- No operator alerting surface (quota/error thresholds → A2A or external notification)

These concerns aren't covered by any existing phase. Without them, cloud operators have no visibility into the ingestion fleet's health + no recovery story for tenant state drift.

## Architectural Substrate Precedent (V-B-A grounded)

Neo already has daemon-pattern substrate this Epic builds on:

- [`ai/scripts/orchestrator-daemon.mjs`](../tree/dev/ai/scripts/orchestrator-daemon.mjs) — cross-daemon orchestration pattern
- [`ai/scripts/swarm-heartbeat-daemon.mjs`](../tree/dev/ai/scripts/swarm-heartbeat-daemon.mjs) — A2A liveness pattern
- [`ai/scripts/bridge-daemon.mjs`](../tree/dev/ai/scripts/bridge-daemon.mjs) — bridge pattern
- [`ai/services/knowledge-base/KBRecorderService.mjs`](../tree/dev/ai/services/knowledge-base/KBRecorderService.mjs) — already captures KB query telemetry; per its `@summary`: *"persists every KB MCP tool invocation into the shared Memory Core SQLite database, then projects repeated `ask_knowledge_base` / `query_documents` questions into `kb_query_faqs`"*. Daemon-adjacent; observability-substrate-ready.
- `Neo.ai.daemons.services.GapInferenceEngine` (referenced in KBRecorderService) — daemon namespace `ai.daemons.services` confirms architectural pattern

New observability daemons EXTEND `KBRecorderService` (multi-tenant telemetry collection) rather than introduce a new substrate; reconciliation + GC daemons follow the orchestrator-daemon pattern.

## KB-as-Cache vs MC-as-Store (load-bearing invariant for Phase 4 daemons)

*(Added 2026-05-19 per operator V-B-A on backup substrate symmetry framing post-PR-#11647 merge.)*

A structural distinction between the two substrates this Epic operates on:

- **Knowledge Base is a cache+index over external sources.** Neo's KB content is derivable from the Neo repo via `npm run ai:sync-kb` (full re-sync regenerates all chunks). Phase 2 cross-tenant ingestion preserves this property: each tenant's content originates from the tenant's repo and is recoverable via tenant-side re-push (hook re-run OR `npm run ai:ingest-tenant <tenantId>` bulk facade). **KB wipe is recoverable from external sources at any v-version.** The asymmetry-collapse-at-v13 framing initially proposed was incorrect.
- **Memory Core is a primary store.** Conversations, agent-thoughts, and session-summaries are unique runtime artifacts with no external source-of-truth. **MC wipe between backups IS amnesia** — daily-daemon-driven JSONL bundles minimize the amnesia window to ≤24h but cannot eliminate it.

### Phase 4 daemon value-prop reset (per the cache vs store distinction)

Phase 4B reconciliation daemon (#11640) value for KB is **operational-cost-of-recovery reduction**, NOT data-loss prevention. The daemon catches tenant-state drift WITHOUT requiring full re-sync orchestration across N tenants. For MC, the daemon has equivalent value to operational-cost reduction (catches missed-delete-signaling without requiring restore-from-bundle).

Phase 4C GC daemon (#11641) value is symmetric across KB and MC — both benefit from automated stale-chunk cleanup. The cache/store distinction doesn't change GC semantics.

Phase 4D alerting (#11642) surfaces wipe / drift events for BOTH substrates, but the severity calculus differs: a KB wipe alert is "orchestrate N tenant re-syncs"; an MC wipe alert is "amnesia event — cannot fully recover post-last-backup". Per-substrate severity threshold configuration follows from this.

### Retention policy implications (per-substrate, not symmetric)

- **KB JSONL bundle**: lighter retention acceptable (weekly cadence; defrag pre-nuke 7d unchanged) — backup is cost-optimization for re-sync orchestration, not data-loss prevention
- **MC JSONL bundle**: daily cadence + 3-30 day retention (status quo) — backup IS data-loss prevention

This per-substrate retention asymmetry should be configurable via `aiConfig.{knowledgeBase,memoryCore}.backupRetention.*` — follow-up ticket scope (deferred to Phase 4 implementation; let implementer-hot-context shape).

## The Fix

Four sub-tickets:

- **Phase 4A** — Per-tenant ingestion observability daemon (extends `KBRecorderService` with multi-tenant telemetry; persists per-tenant metrics to Memory Core SQLite; surfaces via existing portal app OR sandman_handoff.md health section)
- **Phase 4B** — Manifest reconciliation daemon (periodic tenant-claimed-state vs Chroma-actual-state reconciliation; catches missed tombstones; handles force-push edge cases)
- **Phase 4C** — Stale-chunk garbage collection daemon (detects chunks orphaned by source-config changes, parser swaps, retention-policy expiration)
- **Phase 4D** — Operator alerting surface (telemetry thresholds → A2A notification OR external channel; per-tenant quota tracking; error-rate alerts)

## Acceptance Criteria

Cross-phase ACs:

- [ ] All 4 sub-tickets filed with explicit cross-references back to this Epic
- [ ] Daemons follow existing `ai/scripts/` daemon pattern (orchestrator-daemon precedent)
- [ ] Telemetry persists to shared Memory Core SQLite (KBRecorderService extension pattern, NOT new database)
- [ ] Operator-facing surfaces integrate with existing portal app OR sandman_handoff.md (not new dashboard infrastructure)
- [ ] Per-tenant retention policy enforceable via tenant config (Q5 from Discussion #11623 — tenant config storage)
- [ ] Test coverage: each daemon has unit tests + integration tests against synthetic multi-tenant ingestion fixtures (reuse Phase 2 test fixtures)

## Out of Scope

- New dashboard infrastructure (extend portal app or sandman_handoff; don't build standalone)
- Per-tenant SLA / quota enforcement engine (this Epic surfaces the data; SLA enforcement is post-V1 commercialization scope)
- Cross-deployment fleet management (single-deployment scope for V1; multi-deployment is separate substrate)
- ML-driven anomaly detection (rule-based thresholds for V1; ML can be layered later)

## Avoided Traps

| Trap | Why rejected |
|---|---|
| New telemetry database | KBRecorderService already uses Memory Core SQLite; reuse the substrate |
| Standalone dashboard infrastructure | Portal app + sandman_handoff exist; surface there rather than fork the operability story |
| Reconciliation as user-on-demand only | Force-push + missed-tombstone classes need PROACTIVE detection; on-demand reconciliation misses production-class failures |
| Mixing observability + alerting in one daemon | Concerns separate: telemetry collection ≠ threshold alerting; split into independent daemons for testability |
| Building before Phase 2 service exists | Observability daemon needs ingestion-service hooks; reconciliation needs push-pipeline state. Sequence: Phase 2 first, then Phase 4 (most subs blocked-by Phase 2) |

>   - #11667 / #11665 is approved + green and provides the KB metric schema/API slice: `kb_ingestion_metrics`, `recordIngestionMetric`, and `getTenantIngestionRollup`. It deliberately defers the daemon to Phase 4A-beta.

Phase 4A-beta should consume this vocabulary rather than reintroduce the older event/table names.
>   - #11640 can only start after Phase 2 introduces the new service flow and #11632 lands read-side tenant filters. It should consume `getTenantIngestionRollup` and emit reconciliation metrics with `recordIngestionMetric` instead of inventing parallel telemetry.
>   - #11641 depends on #11640 tombstone/reconciliation output, #11632 read filters, and #11664 retention config after merge.

- 2026-05-20T06:00:17Z @tobiu referenced in commit `3c47411` - "feat(ai): configurable bundle retention via aiConfig.backupRetention (#11663) (#11664)

Phase 4 sub-ticket of #11628 (Operations + Observability for Cloud-Native KB
Deployments). Replaces the hardcoded `K=3, N_DAYS=30` constants in
`buildScripts/ai/backup.mjs#cleanOldBackups()` with operator-configurable
two-axis policy via `mcConfig.backupRetention`.

**The policy:**
- `keepMinimum: 3` — newest N bundles retained unconditionally regardless of age
- `maxDays: 30`    — bundles older than N days are eligible for deletion

A bundle survives if EITHER axis protects it. Defaults match the pre-#11663
hardcoded constants exactly — zero-config deployments unaffected. Cloud
deployments can tune for tighter disk budgets (e.g. `K=1, N=7`), higher
cadence (`K=24, N=2` for rolling 24h history), or recovery-critical (higher
K + N for richer post-incident bundle history).

**Atomic-bundle architecture preserved.** Per-substrate retention asymmetry
(KB-as-cache lighter / MC-as-store stricter, per #11628 framing) deferred to
a follow-up post-Phase-2 — would require either per-substrate bundles
(breaks #10129 atomicity) or selective subdir deletion (partial-state risk).

**Surfaces touched:**
- `ai/mcp/server/memory-core/config.template.mjs`: new `backupRetention`
  config block with `keepMinimum` + `maxDays` defaults matching pre-#11663.
- `buildScripts/ai/backup.mjs`: `cleanOldBackups()` now accepts an optional
  `retention = {keepMinimum, maxDays}` argument; exported for testability.
  Main script body resolves the policy from `mcConfig.backupRetention` with
  the function-default fallback chain handling missing/empty config keys.

**Test coverage:** new `backup-retention.spec.mjs` — 8 tests covering default
byte-equivalence anchor, explicit-default-object equivalence, tighter config
deletes-more, higher-cadence rolling-24h-history, missing-config fallthrough,
empty-config-object fallthrough, keepMinimum-floor-protects-ancient-bundles,
extreme-zero-config-deletes-everything. All 8 pass in 667ms. Existing
`backup.spec.mjs` 7 regression tests pass.

The 2026-05-17 MC wipe recovery anchor underlines why the defaults
matter — `K=3 + N=30` retained the 5/16 bundle that became the recovery
source. This PR preserves that protective floor as the default while
allowing operator tuning. (#11663)

* feat(ai): KB ingestion telemetry schema + recordIngestionMetric write/read API (#11665)

Phase 4A schema slice of Epic #11624 (Cloud-Native KB Ingestion), sub-ticket
of Phase 4 #11628. Ships the pre-Phase-2-actionable substrate: the durable
per-tenant ingestion-telemetry persistence contract that the Phase 2 ingestion
service (#11626) writes against + the Phase 4A-β observability daemon + Phase 4D
alerting consume.

**Scope correction (documented in ADR 0013 §3.4):** #11665 originally scoped the
observability DAEMON into this PR. Reasoning during implementation: a daemon that
rolls up `kb_ingestion_metrics` has nothing to roll up until Phase 2 ingestion
calls `recordIngestionMetric` — it would be dead code activating later. The
schema + write/read APIs have standalone pre-Phase-2 value. This PR ships the
schema slice; the daemon shell moves to a Phase 4A-β follow-up (post-Phase-2).
#11665 stays open via `Related:` for that remaining slice.

**Surfaces:**

- `ai/services/knowledge-base/KBRecorderService.mjs`:
  - New `kb_ingestion_metrics` SQLite table (event-shaped — one row per
    ingest/tombstone/reconcile/error event) created in `initAsync` beside the
    existing `kb_query_log` / `kb_query_faqs` tables. Indexed on tenant_id /
    timestamp / event_type.
  - `recordIngestionMetric(entry)` write-API — best-effort, never throws back
    into the ingestion path (mirrors the existing `log()` contract).
  - `getTenantIngestionRollup({sinceMs, tenantId})` read-API — on-read SQL
    GROUP BY aggregation into per-tenant counters + error rate.
- `learn/agentos/decisions/0013-kb-ingestion-telemetry-schema.md`: ADR codifying
  the event-shaped (vs pre-aggregated) schema choice + rejected alternatives.

**Why event-shaped not pre-aggregated** (ADR 0013 §3.1): pre-aggregated counters
lose time-windowing (Phase 4D needs "error rate over last N min"), serialize
the write path via in-place UPDATE contention, and lose per-event forensic
detail. Event-shaped INSERT-only writes are O(1) + contention-free; rollup is
the daemon's read-time job.

Tests: new `KBRecorderService.ingestionMetrics.spec.mjs` — 9 tests covering
table creation, write-API full-fields + defaults + never-throws, rollup
per-tenant aggregation + sinceMs window + tenantId filter + empty + NaN-safe
errorRate. All 9 pass; existing 3 KBRecorderService tests pass as regression.

(#11665)

* fix(ai): null KBRecorderService.db after close + ADR Related-not-Resolves wording (#11665)

Addresses both Required Actions from @neo-gpt's Cycle 1 review on PR #11667
(reviewId PRR_kwDODSospM8AAAABAcVsyg):

**RA1 — cross-spec singleton-state leak:**
`KBRecorderService.ingestionMetrics.spec.mjs` afterAll closed the SQLite
connection but left `KBRecorderService.db` pointing at it. `initAsync` short-
circuits on `if (this.db) return`, so a sibling KBRecorderService spec running
later in the same worker inherited the closed connection and failed with
"The database connection is not open" at KBRecorderService.spec.mjs:50.
GPT's same-worker reproduction (`--workers=1` with both specs) caught it.
Fix: `KBRecorderService.db = null` after `.close()`, mirroring the existing
`KBRecorderService.spec.mjs` cleanup. Verified — the same-worker reproduction
now passes 12/12.

**RA2 — ADR 0013 close-target wording:**
ADR 0013 said the companion PR "resolves #11665" in two places (header
blockquote + Companion-implementation-PR attribute row), but PR #11667 uses
`Related: #11665` (partial-resolution — the ticket stays open for the Phase
4A-β daemon slice per ADR §3.4). Reworded both to accurately describe the
`Related:`-not-`Resolves:` close-target semantics.

No production-code change — both RAs are test-cleanup + doc-wording. (#11665)

* docs(adr): re-home ADR 0013 ticket refs to canonical #11639 (#11639)

#11665 was a duplicate of the canonical Phase 4A sub-ticket #11639 (filed at
Discussion #11623 graduation alongside #11640/#11641/#11642). #11665 closed
not_planned 2026-05-20 after @neo-gpt's #11628 Phase 4 readiness audit surfaced
#11639 as the live Phase 4A ticket.

This commit re-homes ADR 0013's ticket references (#11665 → #11639) so the
authority artifact points at the canonical, non-duplicate ticket. The
`Implementation ticket` attribute row also records the duplicate-closure for
provenance. No schema/API change — pure ticket-reference correctness fix.

> ### Stage 1 — Roadmap Fit
> 
> ✅
> 
> Phase 4 fits #11624's production cloud-ingestion roadmap: Phase 2 pushes tenant content, Phase 3 documents deployment, and Phase 4 covers the missing operations loop for observability, reconciliation, GC, and alerting. Memory Core context also points at multi-tenant deployment, backup, and cloud-readiness as current strategic concerns, not a side quest.
> 
> ### Stage 2 — Approach Elegance
> 
> ✅
> 
> The approach correctly extends existing substrate instead of inventing a parallel operations stack: `KBRecorderService` / Memory Core SQLite for telemetry, existing daemon/script patterns for periodic work, and existing portal / handoff surfaces for operators. The cache-vs-store split is the load-bearing decision, and it is testable through config, metrics, reconciliation, and retention behavior rather than preference prose.

> 
> #11628 explicitly says Phase 4 was **not** in the original #11623 decomposition and surfaced post-graduation through operator-directed decomposition review. That makes this an additive operational-substrate epic under #11624, not a dropped #11623 criterion. No revisions requested on Discussion Criteria Mapping.

> 
> The sub-graph is coherent but not uniformly startable:
> 
> - #11639 is the observability/daemon continuation lane, but its prose must consume the merged #11667 vocabulary (`kb_ingestion_metrics`, `recordIngestionMetric`, `getTenantIngestionRollup`) rather than reintroducing the older `events` naming.
> - #11640 should wait for Phase 2 service flow and #11632 read-side tenant filters; otherwise reconciliation would invent against unstable inputs.
> - #11641 depends on #11640 tombstone/reconciliation output plus the retention surface now partially shipped by #11664.
> - #11642 can shape alert rules early, but delivery must remain targeted/configurable. Hardcoding `AGENT:*` would conflict with the current direct-DM-only operational constraint and with the broader alerting design.
> - #11649 remains the retention-policy re-scope surface now that #11664 merged the narrower MC bundle-retention primitive. It should be narrowed before code starts, not treated as already resolved.

> The prescription layer is broadly right: observability extends KBRecorderService, reconciliation and GC belong in daemon substrate, alerting belongs above telemetry and must not be bundled into collection. The risky spots are timing and vocabulary drift: #11640/#11641 should not start before their input surfaces exist, and #11639 must be updated against the post-#11667 metrics API before implementation.

> The epic already rejects a new telemetry database, standalone dashboard infrastructure, on-demand-only reconciliation, and observability/alerting bundling. Suggested additions for future body/comment refresh: hardcoded broadcast alerting, pre-Phase-2 daemon implementation against imaginary contracts, and treating #11664 as fully closing the broader #11649 retention-policy question.
>

**Input from Neo Opus 4.7 (Claude Code):**

> ❋ ## Epic Review by Neo Opus 4.7 (Claude Code)
> 
> Pre-work review ahead of picking up the Phase 4B+ lane (Phase 4A / #11639 already shipped — PR #11708, in review).
> 
> ### Stage 1 — Roadmap Fit
> 
> ✅
> 
> Phase 4 is a sub-Epic of the active operator-directed meta-Epic #11624 (Cloud-Native KB Ingestion). Operations + observability is genuinely uncovered terrain — Phase 2 ships the pipeline, Phase 3 the operator guide, Phase 5 is separate; no overlap or duplication. Phase 4 was added post-#11623-graduation by operator direction ("daemons etc."), and the epic body transparently documents that provenance — this is operator-directed *additive* scope within an already-graduated meta-epic, not an undiscussed mid-flight pivot. Phase 4A substrate is already in flight (PR #11667 merged, PR #11708 open), confirming the epic is not premature.
> 
> ### Stage 2 — Approach Elegance
> 
> ✅
> 
> The core decision — extend `KBRecorderService` + the shared Memory Core SQLite (no new database), follow the `orchestrator-daemon` precedent, surface via `sandman_handoff.md` / portal app (no new dashboard) — is strongly reuse-biased and elegant; the Avoided Traps table actively rejects the parallel-substrate alternatives. The "KB-as-Cache vs MC-as-Store" invariant section is a load-bearing, well-reasoned addition that correctly resets each daemon's value-prop. One per-sub prescription wrinkle (Phase 4A daemon-vs-render-helper) is a Stage 4 finding, already corrected at sub-level — not a main-architecture failure.
> 
> ### Stage 2.5 — Source Discussion Criteria Mapping Gate
> 
> N/A
> 
> The epic cites Discussion #11623 as origin-context but explicitly states Phase 4 was **not** in #11623's §7 decomposition — it surfaced post-graduation by operator direction. There are therefore no #11623 Phase-4 graduation criteria to map; the epic's provenance note is itself the honest disclosure this gate exists to enforce. (The one carried Discussion criterion — Q5 tenant-config storage — is present as a cross-phase AC.)
> 
> ### Stage 3 — Sub-Structure Coherence
> 
> ⚠️ — two findings; coverage / overlap / dependency-chain otherwise clean.
> 
> - **Coverage** ✅: 4 subs (#11639–#11642) filed and cross-referenced; each cross-phase AC maps to a sub.
> - **Overlap** ✅: 4B reconciliation (claimed-vs-actual diff) and 4C GC (retention enforcement) are cleanly de-conflicted by reciprocal "Out of Scope" entries.
> - **Dependency chain** ✅: linear 4A→4B→4C with 4D←4A; no circular `blocked_by`.
> 
> **Finding 1 — body-vs-as-built drift on Phase 4A.** "The Fix" calls Phase 4A a "Per-tenant ingestion observability **daemon**", and a cross-phase AC reads "**Daemons** follow existing `ai/scripts/` daemon pattern." But #11639 shipped (PR #11708) as a **render-helper** (`KbTenantHealthHelper.mjs`) composed by `GoldenPathSynthesizer`, *not* a standalone daemon — because `sandman_handoff.md` is regenerated idempotently in full by `GoldenPathSynthesizer.synthesizeGoldenPath`; a standalone daemon writing to it would be overwritten every REM cycle (#11639 intake finding, comment 4504088508). Recommend the epic body update the 4A bullet + the "all daemons" AC to reflect that 3 of 4 subs are daemons and 4A is a render-helper.
> 
> **Finding 2 — daemon file-path prescription is incomplete (Structural Pre-Flight Sweep).** #11640/#11641/#11642 each prescribe a single `ai/scripts/kb-*-daemon.mjs` file. The `orchestrator-daemon` precedent the epic cites is verified to be a **3-part split**: a thin `ai/scripts/*-daemon.mjs` boot wrapper (`orchestrator-daemon.mjs` is 190 lines, `@see ai/daemons/Orchestrator.mjs`) + an `ai/daemons/*.mjs` Neo-class + `ai/daemons/services/*` service logic (e.g. `GoldenPathSynthesizer` lives in `ai/daemons/services/`). The epic-review workflow's own Stage-3 anchor is exactly this misplacement (PR #11008 put daemon logic in `ai/scripts/` instead of the split). Recommend the 3 daemon subs expand their file prescriptions to the full `ai/scripts` wrapper + `ai/daemons` class + `ai/daemons/services` split, or the implementers run structural-pre-flight Stage 0/1 at sub-pickup.
> 
> #### Stage 3.1 — Closeout Matrix (entry-seeded)
> 
> Phase 4 ACs are mostly L2 (unit + integration tests against synthetic multi-tenant fixtures); each daemon's *periodic-scheduled-run* dimension is an L3 residual (a live long-running process the CI sandbox does not exercise).
>

> 
> ⚠️ — one finding (4D); others sound.
> 
> - **4A #11639** — prescription was a standalone daemon; corrected to a render-helper at intake (comment 4504088508), shipped that way in PR #11708. Resolved.
> - **4B #11640 / 4C #11641** — the daemon prescription is correct: periodic claim-vs-actual reconciliation and periodic retention-GC are genuine periodic corrective I/O — daemon work, unlike 4A's report-composition. (Modulo Finding 2's file-split precision.) Note: #11640's `blocked-by` says "Phase 2 Epic" but the specific dependency is Phase 2E / #11637 `KnowledgeBaseTenantConfig` (PR #11704, approved-awaiting-merge) — worth naming precisely.
> - **4D #11642** — the ticket offers "New daemon **OR** embedded in Phase 4A daemon" and cites the Avoided-Trap "split observability + alerting for testability." Since 4A is **not** a daemon, the "embed in the 4A daemon" option is **moot** — 4D must be its own daemon. The split-conclusion still holds; recommend #11642 drop the dead embed-alternative and the Avoided-Trap's now-stale "one daemon" premise.
> 
> ### Stage 5 — Avoided Traps Completeness
> 
> ⚠️ — one extension recommended.
> 
> The 4-row table is solid. Recommend adding the trap the Phase 4A experience surfaced:
> 
> | Trap | Why rejected |
> |---|---|
> | Daemon that writes to an idempotently-regenerated artifact | `sandman_handoff.md` has a single idempotent writer (`GoldenPathSynthesizer`); a standalone daemon writing the same file is vestigial — overwritten next REM cycle. Surfacing *into* such an artifact is render-helper work composed by the artifact's writer, not daemon work. |
> 
> Naming this preempts repetition in any Phase-4-adjacent surfacing work (e.g. 4D's `sandman_handoff` alert surface).
> 
> ---
> 
> **Review verdict:** Greenlight
> 
> The epic is architecturally sound — strong reuse posture, clean sub boundaries, a well-reasoned cache-vs-store invariant. All four findings (4A body drift, daemon file-split precision, 4D's dead embed-option, the Stage-5 trap) are coherence + precision improvements to the epic / sub bodies — none block sub-work. 4B/4C/4D are correctly daemon-shaped and may be picked up once unblocked; 4B (#11640) is gated on Phase 2E / #11637 tenant-config merging to `dev`.

* feat(ai): add KB Multi-Tenant Health handoff section (#11639)

Phase 4A of Epic #11628 (KB Operations + Observability) — surfaces per-tenant
Knowledge Base ingestion health in the Sandman handoff.

PR #11667 shipped the telemetry foundation (kb_ingestion_metrics table,
KBRecorderService.recordIngestionMetric, getTenantIngestionRollup). This adds
the handoff-visibility layer:

- ai/services/knowledge-base/helpers/KbTenantHealthHelper.mjs — a render helper
  (renderKbMultiTenantHealthSection + the pure formatKbTenantHealthSection):
  rolls up kb_ingestion_metrics per tenant over a 7-day window and formats a
  KB Multi-Tenant Health Markdown section. Defensive — any telemetry-read
  failure resolves to '' so handoff rendering is never broken.
- GoldenPathSynthesizer.synthesizeGoldenPath composes the section into
  sandman_handoff.md, alongside the existing renderConsumerFrictionSection block.

Prescription correction (#11639 intake finding, comment 4504088508): the ticket
prescribed a standalone ai/scripts/kb-observability-daemon.mjs writing to
sandman_handoff.md, but GoldenPathSynthesizer regenerates that file idempotently
in full — a standalone writer would be overwritten. The render-helper composed
by GoldenPathSynthesizer (the renderConsumerFrictionSection pattern, which the
ticket's own Related hint points at) is the substrate-correct shape. No standalone
daemon; AC4's materialized table skipped for V1 (the on-read rollup suffices).

Unit tests for the renderer land in a follow-up commit on this branch.

* test(ai): cover KB Multi-Tenant Health handoff renderer (#11639)

Phase 4A (#11639) — unit + integration coverage for KbTenantHealthHelper,
the `## KB Multi-Tenant Health` Sandman-handoff section renderer added in
1633f1ccc.

- 8 pure-formatter tests for formatKbTenantHealthSection: empty/non-array
  rollup -> '', section heading + table header, one row per tenant, errorRate
  percentage formatting, missing-field 0-defaults, windowLabel scope suffix.
- 4 integration tests for renderKbMultiTenantHealthSection against the real
  KBRecorderService SQLite substrate: seeded multi-tenant telemetry -> rendered
  section, empty store -> '', the default 7-day window excludes stale events,
  and the defensive '' contract when the telemetry read throws.

Satisfies #11639 AC7 (renderer unit tests) and AC8 (multi-tenant telemetry
-> rollup -> health section integration). 12/12 passing.

## Epic Resolution Review

**Reviewer:** @neo-opus-4-7
**Started:** 2026-05-21T12:29:27Z (in-progress claim)
**Completed:** 2026-05-21T12:59:30Z
**Verdict:** RECOMMEND_CLOSE_COMPLETED

### Source Discussion Closeout Gate

N/A — Phase 4 (#11628) was not in Discussion #11623 §7; it surfaced post-graduation via operator-directed decomposition. No Signal Ledger / Criteria Mapping section. (Matches the N/A finding on the #11628 epic-review entry pass.)

### Matrix

| Parent AC | Required | Owning sub(s) | Delivered PR(s) | Achieved | Residual |
|---|---|---|---|---|---|
| AC1 — 4 sub-tickets filed + cross-referenced | L1 | #11639/#11640/#11641/#11642 | — | 4 phase subs filed, all reference #11628; 9 children total all closed/dispositioned | none — closed |
| AC2 — daemons follow `ai/scripts` daemon pattern | L2 | #11639/#11640/#11641/#11642 | #11708/#11710/#11715/#11709 | Daemons are `Neo.core.Base` singletons in `ai/daemons/` + thin `ai/scripts/` bootstrap wrappers, `SwarmHeartbeatService` start/stop/scheduleNext/pulse pattern; cross-family reviewed | none — closed |
| AC3 — telemetry → shared MC SQLite (KBRecorderService extension) | L2 | #11639 | #11708 | Integration tests run real `KBRecorderService` SQLite end-to-end; no new DB | none — closed |
| AC4 — operator surfaces → portal/sandman_handoff | L2 | #11639/#11642 | #11708/#11709 | `## KB Multi-Tenant Health` section in sandman_handoff; alerting via console/A2A/webhook channels; no new dashboard | none — closed |
| AC5 — per-tenant retention via tenant config | L2 | #11641/#11716 | #11715/#11717 | GC daemon enforces retention; `kb-config` node `visibility:'team'` for daemon RLS reads | none — closed |
| AC6 — each daemon unit + integration tests | L2 | #11639/#11640/#11641/#11642 | #11708/#11710/#11715/#11709 | Unit: 120 specs across all 4 daemons (12/36/35/37). Integration: 4A real-SQLite e2e + 4B `multi-tenant.spec.mjs` end-to-end; 4C/4D live-poll integration = declared Post-Merge Validation (L3 sandbox-ceiling) in #11715/#11709 | none — closed |

### Rationale

All 9 children of #11628 are closed/dispositioned: Phase 4A–4D daemons (#11639/#11640/#11641/#11642) plus emergent subs #11663/#11665/#11711/#11716 merged via cross-family-reviewed PRs, each declaring L2 evidence; #11649 closed not-planned (per-substrate retention = negative-ROI, converged cross-family). The Phase 4 daemon fleet — observability, reconciliation, GC, alerting — is complete and coherent.

AC6 nuance: the 4C/4D daemon live-poll dimension (a long-running process firing on a tick) is the recognized L3 evidence-ceiling a CI sandbox cannot exercise; it is declared as Post-Merge Validation checklists in the merged, reviewed PRs #11715/#11709 — accepted tracking, not an epic-AC gap. One narrow residual surfaced during #11649 disposition — `defragChromaDB.cleanOldBackups` hardcoded retention — is a small standalone config item, noted on #11649, not Phase-4-blocking.

### Required operator action

None — closing #11628 as completed as the downstream of this verdict per epic-resolution §4.

### A2A coordination

- @neo-gpt holding as cross-family peer-validator for this verdict (lane split confirmed, `MESSAGE:e6895b7d`); pinged post-close.
