Oliver Kieselbach 63ea2e3cee feat(mcp): search_docs — customer documentation as a third search corpus
The MCP server could answer telemetry questions ("why did this session fail")
but not product ones ("how do I deploy the agent", "where is my data stored").
Those answers already exist in the autopilotmonitor-docs bundle; search_docs
makes them semantically searchable.

Deliberately a separate index from search_knowledge: rules and prose answer
different questions, and sharing one topK would dilute both. Registered for
every role — published documentation carries no tenant data — and skipped
entirely when no corpus was baked in, so a doc-less build advertises no
broken tool.

Corpus handling:
- Chunked at h2/h3 and <details>/<summary>, each chunk prefixed with a
  "Page > Section > Subsection" breadcrumb so a mid-page hit is self-describing.
- Newlines are normalized before any parsing. This is a correctness
  precondition, not cosmetics: the bundle ships CRLF and JS `.` does not match
  \r, so /^(#{2,3})\s+(.*)$/ matched zero headings — silently, degrading every
  page to unlabelled paragraph splits.
- Two size exceptions: tables are never split (a split table leaves `| --- |`
  rows with no header), and unbroken changelog lists split at line level (left
  whole, their tails fall outside the model window and become unsearchable).
- Short sections are kept — a one-line answer is often the best hit, and the
  breadcrumb supplies the context a short body lacks.

Build and delivery:
- Docs are embedded at image build time into an optional third
  PrecomputedSection. Optional so a checkout without the docs repo does not
  invalidate the rules and event-type vectors; the reverse (server has docs,
  file does not) is staleness and is rejected.
- The deploy workflow checks the public docs repo into the build context and
  passes its SHA as DOCS_COMMIT, which /health reports alongside the chunk
  count — editing the docs does not update a running server, so staleness is
  made checkable rather than memorable.
- Embeddings are rounded to 6 decimals on serialize: 55% smaller index (2.63
  vs 5.88 MB) for a ~1e-5 norm error against a 1e-3 tolerance. indexPrecomputed
  now asserts unit norm, since the hydrate path never checked it.

Infra: the Bicep template was two changes behind the live deployment (EU
cutover and ACR hardening, both applied directly in Azure). Reconciled against
the running resources — managed-identity image pull replaces the admin
credentials and the acr-password secret — and infra/ is no longer gitignored so
it stops drifting. Container raised to 0.5 vCPU / 1.0 GiB for the cold-start
query-embedder load. The template does not model the mcp.autopilotmonitor.com
custom domain, so a full deployment would remove it; the header warns about it.

Verified: 428 tests pass; 45 pages produce 324 chunks; sample queries hit the
right page top-1/2; all 8 derived URLs return 200 live; the precompute output
is accepted by the boot validator and a mutated corpus is rejected.

# Log
## 2026-07-21
* **Creation**: Added `mcp/docs-corpus.md` (new `mcp/` section) — the MCP server gains `search_docs`, a third semantic corpus built from the published customer documentation repository (`autopilotmonitor-docs`, checked out into the Docker build context by the deploy workflow). Documents the h2/h3 + `<details>` chunking with breadcrumb prefixes, the two deliberate size exceptions (tables never split, unbroken changelog lists split at line level), the CRLF precondition (`.` does not match `\r` in JS — headings silently stop matching, which produced 286 wrong-but-plausible chunks before it was found), the optional `docs` section in `search-index.json` and its validation asymmetry, embedding rounding to 6 decimals, and the cross-repo coupling: a docs edit reaches clients only after an MCP redeploy, made checkable via `DOCS_COMMIT` on `/health`. Container resources raised to 0.5 vCPU / 1.0 GiB for the cold-start query-embedder load.
## 2026-07-20
* **Update**: Extended `rules/gather-rule-phase-scoping.md` with the `phase_exit` trigger — the closing bookend to `phase_change`, for one-shot collection when a phase is LEFT (e.g. "state at the end of Account Setup"). Documents the evaluation-before-phase-advance rule (triggerPhase match and scope gate see the phase being left), firing into `Failed`, the disjoint `exit:` dedup key space, and why no ConfigVersion bump is needed (no new field — old agents simply never fire the rule).
* **Update**: Reworked `agent/mdm-reboot-coalescing.md` after the first real enrollment (session b2e890c1): 2800 records are now **aggregated per burst** into ONE neutral Info event (`rebootUris[]`/`uriCount`/`firstRebootUri`; watermark persisted at flush so a pre-emit reboot kill loses nothing); the raw event no longer claims a reboot — ANALYZE-ESP-005 is gated on an actually-observed `system_reboot_detected`. **Removed** the Shell-Core `esp_reboot_coalescing` event entirely: the "RebootCoalescing" token appears in the routine `SubcategoryProcessing_Started` bootstrap marker on every enrollment (false positive by construction). Verified 2800 description shape recorded.
* **Creation**: Added `agent/mdm-reboot-coalescing.md` — the agent now attributes the "unexpected mid-ESP reboot + second sign-in" pattern (PMPC research) to the device-assigned policy URIs that forced it: new `MdmRebootPolicyTracker` (DM-Enterprise EventID 2800, per-URI `mdm_policy_reboot_required` events, cross-restart RecordId watermark), a `RebootCoalescing` branch in `ShellCoreTracker` (`esp_reboot_coalescing`, backfill-emitting by design), and the `ANALYZE-ESP-005` advisory (reassign device → user groups). ConfigVersion 35; event types deliberately distinct from `system_reboot_detected` so RebootCount stays uninflated.
* **Creation**: Added `backend/business-timestamps.md` (new `backend/` section) — the 2026-07-18 migration reset every row's system Timestamp, exposing that AuditLogs/OpsEvents/Events had (unknowingly) displayed and filtered on it all along; documents the `OccurredUtc` column, the RowKey decoders and RowKey-range date/retention clauses in `BusinessTimestamp`, the GUID-guard trap, the audit/ops backfill endpoint, and the "system Timestamp is never authoritative" migration rule.
* **Creation**: Added `rules/gather-rule-phase-scoping.md` (new `rules/` section) — gather rules gain `activePhases` (run only during listed phases), `activeFromPhase` (sticky latch from a phase onwards, never via Failed) and `emitMode: "on_change"` (canonical-hash result dedup with `suppressedPolls` observability), ConfigVersion 34. Includes the prerequisite backend fix: the custom-rule toggle PUT no longer wipes the stored rule definition (partial-merge in `GatherRuleService.UpdateRuleAsync`).
## 2026-07-18
* **Creation**: Added `agent/endpoint-migration.md` — config-channel agent re-home (`MigrateToApiBaseUrl` on `GET agent/config`, ConfigVersion 33): backend or per-tenant API-URL moves without DNS indirection (impossible due to mTLS/Flex-TLS). Live-fetch-only with cache strip, `AgentEndpointMigrationRules` allowlist validated on both sides, one hop, kill-switch wins. Built as the lesson from the 2026-07-18 WEU→GWC cutover, which hard-cut all in-flight agents.
## 2026-07-17
* **Creation**: Added `agent/build-counter-blob.md` — agent build numbers now come from a shared public counter blob (`buildcounter-v{N}.txt`, reserve-before-build with ETag-CAS) so local `build.ps1` and CI `build-agent.yml` builds can never mint the same number. Documents the CI parity fixes (SummaryDialog.exe.config in the ZIP, EXE-vs-manifest version check, hash-oracle update gated on stable cutover) and the Sigstore provenance attestation on CI-built ZIPs.
## 2026-07-16
* **Creation**: Added `agent/autopilot-ztd-diagnostics.md` — reference for Windows' own ZTD diagnostic surfaces (ModernDeployment Autopilot event IDs incl. 807/809/815/908, the `Diagnostics\Autopilot` registry key, deployment-service endpoints, known-issue error-code map with KB fixes). Backs the agent's `ZtdEvidence` collector (`ztdVerdict` on `autopilot_profile_missing`) and the backend known-issue rules; sources carry a re-check RSS feed.
## 2026-07-13
* **Removal**: Moved `customer-graph-add-on-permissions.md` out of this contributor bundle into the customer documentation repository (`reference/optional-graph-permissions.md`). It was customer-facing product content and did not belong in the tech-docs bundle; removed the entry from `index.md`.
* **Creation**: Added `agent/hello-wizard-unskip.md` — session 772fe502 fix: the `HelloWizardStarted` decision signal (prevention veto + un-skip cure for the policy-disabled Hello shortcut) and the HelloTracker confirmation second read against flip-flopping WHfB CSP values.
## 2026-07-11
* **Creation**: Added the `agent/` section — three concept documents on the V2 agent: `agent/overview.md` (runtime, collectors, telemetry pipeline), `agent/decision-engine.md` (DecisionCore reducer, signals, A/B/C completion arms, invariants), `agent/logs-and-persistence.md` (persisted artifacts, signal log vs spool, recovery/replay flow) plus `agent/index.md`.
* **Creation**: Converted `docs/` into an OKF v0.1 knowledge bundle — added YAML frontmatter to `architecture.md`, `mcp-oauth-flow.md`, and `customer-graph-add-on-permissions.md`; created `index.md` and this log.
