Resolves #12158

Authored by Opus 4.8 (Claude Code). Session af888fcb-6a68-45bd-8a34-13be477733b1.

FAIR-band: in-band [11/30]

Evidence: L1 (documentation-only; accuracy verified against the shipped ADR 0017 + config.template.mjs / docker-compose.yml ground truth). No runtime AC — the effect is reader-facing doc accuracy.

Why this is needed

Epic #12153 shipped the one-flat-unified-Chroma-store migration (subs: ADR, rename, defrag, release-zip — all merged), but the cloud-deployment + restoration guides still described the retired pre-migration topology: three collections under a knowledge-base-named store, the old /chroma/chroma cloud path, and — most dangerously — a restoration runbook that rm -rfs the retired chroma/knowledge-base/ and chroma/memory-core/ folders. #12158 is the docs sub: bring the guides in line with the shipped reality.

What changed

  • Overview.md (topology anchor): rewritten to ADR 0017 — one flat unified store (.neo-ai-data/chroma/unified local, /chroma/unified cloud via PERSIST_DIRECTORY), four realms as collections (neo-knowledge-base / neo-agent-memory / neo-agent-sessions / neo-native-graph), isolation by collection + metadata, collection-scoped KB shipping, KB-as-cache / MC-as-store recovery — never by directory or daemon split.
  • PipelineWiring.md: Chroma volume /chroma/chroma/chroma/unified (via PERSIST_DIRECTORY).
  • Day0Tutorial.md + Security.md: topology-mode + Related ADR references repointed from ADR 0003 to the governing ADR 0017 (which amends 0003).
  • RestorationRunbook.md (recovery model — safety fix): removed the stale-and-dangerous rm -rf chroma/knowledge-base/* and rm -rf chroma/memory-core/* folder-deletes (those folders are retired; on the flat store, naively adapting them to chroma/unified would destroy the shared store including the irreplaceable Memory Core). Reframed KB recovery as collection-scoped deterministic rebuild (ai:sync-kb) and MC recovery as collection-scoped SDK mode: 'replace' import, each with an explicit "never rm -rf the shared chroma/unified folder" warning.

Deltas from ticket

  • AC1 (cloud docs reflect flat unified store + parity + collection-scoped shipping): covered across Overview / PipelineWiring / Day0Tutorial / Security.
  • AC2 (maintenance docs reflect collection-group defrag + recovery model): the recovery-model half is covered by the RestorationRunbook rewrite (KB-as-cache / MC-as-store, collection-scoped). The collection-group defrag is governed by ADR 0017 §5 + the defrag code; no maintenance guide describes the defrag operation (swept learn/DeploymentCookbook.md already says "unified vector-store primitive" / topology.mode === "unified"), so there was no stale defrag prose to correct. Flagging this scope read explicitly rather than inventing a defrag guide.
  • Configuration.md: the fix-list named it, but it carries no chroma / persist-path content (swept — no engines.chroma / persist refs), so no edit was warranted; not forcing one.

Substrate slot-rationale (touches learn/agentos/**)

  • Modified 5 existing guides (Overview, PipelineWiring, Day0Tutorial, Security, RestorationRunbook): disposition keep — these are operator-facing deployment/recovery docs, not loaded rule substrate; the change is a pure accuracy correction to match the shipped ADR 0017 reality (zero net-new sections; net -4 lines). The RestorationRunbook edit additionally removes an active foot-gun (folder-delete of the shared store). No always-loaded substrate is touched.

Test Evidence

  • Documentation-only; no code paths. Accuracy verified against ground truth: ai/config.template.mjs:259 (…/chroma/unified), ai/deploy/docker-compose.yml (PERSIST_DIRECTORY=/chroma/unified), and ADR 0017. Final repo-wide sweep confirms no remaining chroma/chroma / chroma/knowledge-base / chroma/memory-core references outside ADR 0017's intentional historical context. git diff --check clean.

Post-Merge Validation

  • A fresh operator following RestorationRunbook recovers the KB via ai:sync-kb and the MC via the SDK import without ever deleting the shared chroma/unified store folder.

Decision Record impact: none — documents the already-governing ADR 0017; no ADR change.

PR Review Summary

Status: Approved

🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

  • Decision: Approve
  • Rationale: Approve because the PR corrects operator-facing deployment/restoration guidance to match the already-merged unified-store substrate, removes an unsafe folder-delete recovery path, and does not introduce new runtime behavior. The only live caveat is merge-gate hygiene: integration-unified was still pending at review time, so human merge should wait for that required check to finish green.

Peer-Review Opening: Reviewed as a docs-only #12158 closeout against ADR 0017, current config/compose ground truth, and the changed guide surfaces.


🕸️ Context & Graph Linking

  • Target Epic / Issue ID: Resolves #12158
  • Related Graph Nodes: Epic #12153; ADR 0017; ADR 0003; PR #12159; aiConfig.engines.chroma.dataDir; PERSIST_DIRECTORY=/chroma/unified; neo-knowledge-base; neo-agent-memory; neo-agent-sessions; neo-native-graph.

🔬 Depth Floor

Challenge OR documented search (per guide §7.1):

Documented search: I actively looked for stale destructive rm -rf Chroma guidance, stale /chroma/chroma and per-realm persist-folder references in the changed deployment/restoration guide surfaces, close-target hazards in PR body/commit messages, and Configuration.md drift from the ticket's original fix-list. I found no blocking defects. One non-blocking source-authority note remains: ADR 0017 itself still says Status: Proposed even though #12154 is closed and PR #12159 merged on 2026-05-29; that status-line cleanup is pre-existing and outside #12158's guide-sync diff, not a merge blocker for this PR.

Rhetorical-Drift Audit (per guide §7.4):

Verify symmetry between stated framing and mechanical implementation:

  • PR description: framing matches what the diff substantiates; five guide files align with ADR 0017's flat unified store model.
  • Anchor & Echo summaries: N/A for methods/classes; modified prose uses durable architecture anchors rather than ticket-cycle narration.
  • [RETROSPECTIVE] tag: N/A; none introduced.
  • Linked anchors: ADR 0017, ADR 0003 amendment, #12154, and #12159 support the unified-store authority. The stale ADR 0017 status line is noted above as adjacent debt, not caused by this PR.

Findings: Pass with the non-blocking ADR-status note above.


🧠 Graph Ingestion Notes

  • [KB_GAP]: None in the PR. The local Knowledge Base query did not surface ADR 0017, so review grounding came from local ADR/config/compose files instead of KB synthesis.
  • [TOOLING_GAP]: None blocking. gh network reads intermittently failed in sandbox and were retried with approved escalation; local and GitHub evidence were still obtained.
  • [RETROSPECTIVE]: The important substrate value is the RestorationRunbook correction: recovery is collection-scoped in the flat unified store, and deleting the shared Chroma folder would risk Memory Core data loss.

🎯 Close-Target Audit

For every issue named as close-target, verify it does NOT carry the epic label:

  • Close-targets identified: Resolves #12158 in the PR body.
  • For #12158: live issue labels are documentation and ai; no epic label.
  • Branch commit messages after fetching current origin/dev contain no magic close keyword; the single branch commit subject only references (#12158).

Findings: Pass.


📑 Contract Completeness Audit

  • Originating ticket contains explicit ACs for cloud docs and maintenance/recovery docs.
  • Implemented PR diff maps to those ACs: Overview/PipelineWiring/Day0Tutorial/Security cover cloud topology and ADR references; RestorationRunbook covers collection-scoped recovery and removes the unsafe folder-delete model.

Findings: Pass. No separate Contract Ledger matrix is required for this docs-only guide alignment because no API, runtime contract, tool surface, or public method signature is introduced.


🪜 Evidence Audit

  • PR body contains an Evidence: declaration line.
  • Achieved evidence is sufficient for the scope: L1 documentation accuracy verified against ADR/config/compose ground truth; no runtime AC is introduced.
  • Evidence-class collapse check: review language does not promote this to runtime proof.

Findings: Pass.


📡 MCP-Tool-Description Budget Audit

Findings: N/A — the PR does not touch ai/mcp/server/*/openapi.yaml or MCP tool descriptions.


🔗 Cross-Skill Integration Audit

  • No skill files, always-loaded instruction substrate, MCP tool surfaces, wire formats, or new workflow conventions are changed.
  • The docs cite existing ADR authority rather than creating a new convention that other skills must learn.

Findings: Pass — no integration gaps for this PR scope.


🧪 Test-Execution & Location Audit

  • Branch checked out locally: docs/12158-unified-store-guides at 174188030f464846f30f1dcef5f0c1de86424fce.
  • Canonical Location: N/A — no test files changed.
  • If a test file changed: N/A.
  • If code changed: N/A — documentation-only. I ran git diff --check origin/dev...HEAD; it passed. GitHub lint, lint-pr-body, CodeQL, Analyze, and unit were passing at review time; integration-unified was still pending.

Findings: No tests needed for the docs diff; pending CI remains a human merge-gate condition.


📋 Required Actions

No required actions — eligible for human merge once the still-running required check finishes green.


📊 Evaluation Metrics

  • [ARCH_ALIGNMENT]: 94 - 6 points deducted only for the adjacent pre-existing ADR 0017 status-line mismatch; the PR's own guide changes correctly follow the one-daemon, one-flat-store, collection-scoped recovery architecture.
  • [CONTENT_COMPLETENESS]: 90 - 10 points deducted because the PR intentionally leaves the ADR status cleanup outside scope; within the changed guides, the topology, path, ADR-reference, and recovery warnings are complete.
  • [EXECUTION_QUALITY]: 90 - 10 points deducted because integration-unified was still pending at review time; the local docs checks and all inspected semantics are clean, and no code/test placement risk exists.
  • [PRODUCTIVITY]: 92 - 8 points deducted because the defrag half of AC2 is satisfied by an absence-of-stale-guide finding rather than a direct guide edit; the dangerous recovery guidance and cloud topology drift are fixed.
  • [IMPACT]: 65 - Operationally meaningful documentation safety fix: it prevents a plausible shared-store deletion mistake and aligns cloud deployment prose with ADR 0017, but it does not alter runtime behavior.
  • [COMPLEXITY]: 28 - Low-to-moderate: five markdown files, no code paths, but the review/authoring requires cross-checking ADR 0017, config, compose, issue scope, and stale recovery semantics.
  • [EFFORT_PROFILE]: Quick Win - High safety value relative to a compact docs-only diff.

Merge recommendation: approve the PR shape; wait for integration-unified to complete before @tobiu merges.
