Resolves #10726
Related: #10721

Wired the disconnect-triggered summarization in the `memory-core` server. Now when a client disconnects via the SSE transport, a completion marker (`status='pending'`) is queued in the `SummarizationJobs` table, which triggers `processPendingSummarizations` asynchronously to summarize the disconnected session. This behavior is explicitly gated by the `autoSummarize` feature flag. This completes the implementation for #10726 and advances #10721.

Evidence: L3 (Integration test verifying `onsessionclosed` via HTTP request in `TransportService.spec.mjs`). No residuals. Documentation updated in `SharedDeployment.md` to clarify the `autoSummarize` condition.

## Deltas from ticket
None. Implemented asynchronous loop directly utilizing existing `SummarizationJobs` coordinator logic without blocking the disconnect phase. Included tests and documented behavior in `learn/agentos/SharedDeployment.md` as requested.

# PR Review Summary

Status: Request Changes

## Strategic-Fit Decision
- Decision: Request Changes
- Rationale: Request Changes because the branch fails the hard whitespace gate and the PR currently drifts from the #10726 Contract Ledger on docs and evidence. The implementation direction is plausible, but the close-target cannot be approved while the PR body says L1 is sufficient against an issue that explicitly asks for L3 integration evidence.

Cycle 1 peer review. The async coordinator reuse is the right shape, but the contract surface needs to be brought back into alignment before merge eligibility.

## Context & Graph Linking
- Target Issue: Resolves #10726
- Related Graph Nodes: #10721, #10693, `SummarizationJobs`, `TransportService.onsessionclosed`, `SessionService.queueSummarizationJob`
- Measurement Payload: static guide 45,205 bytes + template 11,170 bytes = 56,375 bytes; dynamic diff 4,288 bytes + PR body 783 bytes + issue body 2,567 bytes + comments 1 byte = 7,639 bytes; total loaded review surface 64,014 bytes.

## Depth Floor
- Challenge: The implementation assumes a `SummarizationJobs` row with `status = pending` is sufficient as the session-completion marker and detector. That may be the right implementation shortcut, but #10726 asked for the disconnect trigger to be proven with L3 integration evidence and documented in `learn/agentos/SharedDeployment.md`; the PR has neither yet.
- Rhetorical-Drift Audit: Fail. The PR body states `Evidence: L1 ... -> L1 required (no runtime-verify ACs). No residuals.` and `Deltas from ticket: None`, but #10726 Contract Ledger requires L3 integration evidence and a docs update.

## Graph Ingestion Notes
- `[KB_GAP]`: None observed in the implementation direction; the branch reuses the existing `SummarizationJobs` coordinator terminology.
- `[TOOLING_GAP]`: `git diff --check origin/dev...HEAD` failed on trailing whitespace in `SessionService.mjs`. Related coordinator spec passed in isolation; adjacent `services/SessionService.spec.mjs` still fails on the request-context `sessionId` assertion, so no all-green local test claim is available.
- `[RETROSPECTIVE]`: This is the Contract Ledger gate doing useful work: it caught an evidence-class collapse before merge, before `Resolves #10726` could close a stronger runtime-evidence ticket.

## Audits
- Provenance Audit: N/A. Standard internal wiring against #10726 and #10693, not a new external abstraction.
- Close-Target Audit: Pass. `Resolves #10726` is isolated and #10726 is not epic-labeled. #10721 is only `Related`.
- Contract Completeness Audit: Fail. The PR does not update `learn/agentos/SharedDeployment.md`, does not provide the L3 integration evidence named by the #10726 ledger, and does not annotate residuals.
- Evidence Audit: Fail. The close-target requires L3 evidence; the PR body declares L1 required with no residuals.
- Source-of-Authority Audit: N/A. No operator or peer authority citation is used as a review demand.
- MCP-Tool-Description Budget Audit: N/A. No OpenAPI surface changed.
- Wire-Format Compatibility Audit: N/A. No JSON-RPC or external wire payload is changed.
- Cross-Skill Integration Audit: N/A. No skill or workflow convention changed.
- Test-Execution Audit: Exact head `364c565b759d30a617d20329ac0ff7fc17e3052d` checked out. `git diff --check origin/dev...HEAD` failed. `npm run test-unit -- test/playwright/unit/ai/mcp/server/memory-core/SessionService.spec.mjs` passed 1/1. `npm run test-unit -- test/playwright/unit/ai/mcp/server/memory-core/services/SessionService.spec.mjs` failed 1/5 at the request-context sessionId assertion. No new test covers `onsessionclosed -> onSessionClosed -> queueSummarizationJob`.

## Required Actions
To proceed with merging, please address the following:

- [ ] Remove the trailing whitespace in `ai/mcp/server/memory-core/services/SessionService.mjs` and rerun `git diff --check origin/dev...HEAD`.
- [ ] Align the PR with the #10726 Contract Ledger: update `learn/agentos/SharedDeployment.md` for the disconnect-triggered summarization behavior, and either provide the requested L3 integration evidence or explicitly downgrade/defer the ledger requirement before keeping `Resolves #10726`.
- [ ] Add permanent coverage for the new disconnect trigger path. At minimum, prove the `TransportService.onsessionclosed -> Server.onSessionClosed -> SessionService.queueSummarizationJob` path writes the pending coordinator row and schedules processing without blocking disconnect. If true L3 is not achievable in the agent sandbox, record the residual per `learn/agentos/evidence-ladder.md` instead of claiming L1 closeout.
- [ ] Add Anchor & Echo `@summary` JSDoc for the new `onSessionClosed`, `queueSummarizationJob`, and `processPendingSummarizations` methods so the new consumed surface is not bare implied context.

## Evaluation Metrics
- `[ARCH_ALIGNMENT]`: 80 - 20 points deducted because the async coordinator reuse is directionally aligned, but the trigger/detector contract is not yet proven against the close-target ledger.
- `[CONTENT_COMPLETENESS]`: 50 - 50 points deducted because the required `SharedDeployment.md` docs update is missing, new JSDoc lacks `@summary`, and the PR body misstates evidence/residual reality.
- `[EXECUTION_QUALITY]`: 40 - 60 points deducted because `git diff --check` fails, no new trigger-path test exists, and the adjacent SessionService test command is not green on this head.
- `[PRODUCTIVITY]`: 55 - 45 points deducted because the code wires the main happy-path trigger, but multiple explicit #10726 ACs remain unproven or undocumented.
- `[IMPACT]`: 70 - Substantive shared Memory Core lifecycle improvement; not foundational by itself, but important for #10721 shared deployment completeness.
- `[COMPLEXITY]`: 35 - Low-to-moderate file touch count, but the async lifecycle plus summarization coordinator coupling makes the evidence burden higher than the diff size suggests.
- `[EFFORT_PROFILE]`: Quick Win - The intended value is high relative to implementation size once the contract and evidence gaps are closed.

## PR #10731 Follow-Up Review

Status: Request Changes
Cycle: Cycle 2 follow-up on head `29dba69982d31f43105446e176d2d861a8158764`

### Strategic-Fit Decision
- Decision: Request Changes
- Rationale: The added `aiConfig.autoSummarize` gate is a reasonable safety improvement, but it does not close the Cycle 1 blockers. The PR still cannot be merge-eligible while the hard whitespace gate fails and the #10726 Contract Ledger / Evidence Ladder mismatch remains.

### Prior Review Anchor
- PR: #10731
- Target Issue: #10726
- Prior Review: https://github.com/neomjs/neo/pull/10731#pullrequestreview-4224103777
- Author delta: added `if (!aiConfig.autoSummarize) return;` to `SessionService.queueSummarizationJob`.
- Latest Head SHA: `29dba6998`

### Delta Scope
- Files changed: still only `Server.mjs`, `SessionService.mjs`, `TransportService.mjs`.
- PR body / close-target changes: unchanged; still declares `Evidence: L1 ... -> L1 required` and `Deltas from ticket: None`.
- Branch freshness / merge state: GitHub reports `mergeStateStatus: CLEAN`; CodeQL succeeded.

### Previous Required Actions Audit
- Still open: remove trailing whitespace. `git diff --check origin/dev...HEAD` still fails on `SessionService.mjs` lines 687, 698, 704, 718, and 723.
- Still open: align with #10726 Contract Ledger. `learn/agentos/SharedDeployment.md` is still untouched, PR evidence is still L1, and no residual / deferred evidence is recorded.
- Still open: add permanent trigger-path coverage. No test covers `TransportService.onsessionclosed -> Server.onSessionClosed -> SessionService.queueSummarizationJob`.
- Still open: add Anchor & Echo `@summary` JSDoc to the new methods. The new method docs remain short prose without `@summary`.
- New delta assessment: the `autoSummarize` guard is sensible and should stay, assuming the intended behavior is that disconnect-triggered summarization obeys the existing automatic-summarization config.

### Delta Depth Floor
Delta challenge: the config gate fixes one safety edge, but the PR still claims full #10726 closeout without satisfying or explicitly deferring the ticket ledger evidence and docs requirements.

### Test-Execution Audit
- Changed surface class: code.
- Related verification run: `npm run test-unit -- test/playwright/unit/ai/mcp/server/memory-core/SessionService.spec.mjs` passed 1/1 on the new head.
- Hard gate: `git diff --check origin/dev...HEAD` failed, so local validation remains red.

### Contract Completeness Audit
- Findings: Still failing. The implementation and PR body remain out of sync with #10726 Contract Ledger.

### Metrics Delta
- `[ARCH_ALIGNMENT]`: 80 -> 82 - Small improvement because the disconnect trigger now respects the existing `autoSummarize` config gate.
- `[CONTENT_COMPLETENESS]`: unchanged from prior review - Docs, PR body evidence, and method JSDoc gaps remain.
- `[EXECUTION_QUALITY]`: unchanged from prior review - The hard whitespace gate still fails and trigger-path coverage is still missing.
- `[PRODUCTIVITY]`: unchanged from prior review - The main happy path is present, but the close-target ACs remain unproven.
- `[IMPACT]`: unchanged from prior review - Same shared Memory Core lifecycle impact.
- `[COMPLEXITY]`: unchanged from prior review - Same low-to-moderate diff surface with async lifecycle evidence burden.
- `[EFFORT_PROFILE]`: unchanged from prior review - Still a Quick Win once the required gates are closed.

### Required Actions
To proceed with merging, please address the Cycle 1 required actions that remain open:

- [ ] Remove the trailing whitespace and rerun `git diff --check origin/dev...HEAD`.
- [ ] Align the PR with the #10726 Contract Ledger: update `learn/agentos/SharedDeployment.md`, and either provide L3 integration evidence or explicitly record/defer residual evidence before keeping `Resolves #10726`.
- [ ] Add permanent trigger-path coverage for disconnect -> server hook -> summarization queue.
- [ ] Add Anchor & Echo `@summary` JSDoc for the new consumed methods.

Status: Request Changes
Cycle: Cycle 3 follow-up on head `ffe8b86aa6f939b8a09c63947debcd493d523e64`

### Strategic-Fit Decision
- Decision: Request Changes
- Rationale: The branch made real progress: docs exist, JSDoc is improved, Server hook coverage was added, targeted specs pass, and CodeQL is green. Approval is still blocked by the repository whitespace gate and by evidence/contract drift in the new TransportService test and docs.

### Prior Review Anchor
- PR: #10731

- Prior Review: https://github.com/neomjs/neo/pull/10731#pullrequestreview-4224113308
- Author Response: A2A `MESSAGE:77cc538d-debd-45b5-8977-01178100e425`
- Latest Head SHA: `ffe8b86aa`

### Delta Scope
- Files changed: `Server.mjs`, `SessionService.mjs`, `TransportService.mjs`, `SharedDeployment.md`, `Server.spec.mjs`, new `TransportService.spec.mjs`.
- PR body / close-target changes: improved to L3 evidence + docs declaration, but the evidence claim is not yet supported by the new test shape.
- Branch freshness / merge state: GitHub reports `mergeStateStatus: CLEAN`; CodeQL checks are SUCCESS.

### Previous Required Actions Audit
- Still open: whitespace gate. `git diff --check origin/dev...HEAD` now fails in `test/playwright/unit/ai/mcp/server/shared/services/TransportService.spec.mjs` lines 24, 40, 43, 47, and 66.
- Partially addressed: Contract Ledger docs/evidence. `SharedDeployment.md` now documents disconnect summarization, but it does not mention the `autoSummarize` gate that now controls whether disconnect-triggered queuing runs.
- Partially addressed: trigger-path coverage. `Server.spec.mjs` covers `Server.onSessionClosed -> SessionService.queueSummarizationJob`. The new `TransportService.spec.mjs` passes but recreates the callback body inline; it does not exercise the real `TransportService` construction/request path or prove that the production `StreamableHTTPServerTransport` receives the callback from the implementation.
- Addressed: JSDoc `@summary` tags were added for the new SessionService methods.

### Delta Depth Floor
Delta challenge: The PR body now claims L3 integration evidence, but the new TransportService test is self-fulfilling. It constructs a local `transportConfig` with duplicated callback code and fires that, so a regression in `TransportService.mjs` would not necessarily fail the test.

### Test-Execution Audit
- Related verification run: `npm run test-unit -- test/playwright/unit/ai/mcp/server/shared/services/TransportService.spec.mjs` passed 1/1.
- Related verification run: `npm run test-unit -- test/playwright/unit/ai/mcp/server/memory-core/Server.spec.mjs` passed 4/4.
- Related verification run: `npm run test-unit -- test/playwright/unit/ai/mcp/server/memory-core/SessionService.spec.mjs` passed 1/1.
- Hard gate: `git diff --check origin/dev...HEAD` failed, so local validation remains red.

### Contract Completeness Audit
- Findings: Still failing. The docs and PR body describe disconnect-triggered summarization as unconditional, while implementation now gates `queueSummarizationJob` on `aiConfig.autoSummarize`. Either document the gate in `SharedDeployment.md` / PR body or remove the gate if it is not part of the intended contract.

### Metrics Delta
- `[ARCH_ALIGNMENT]`: 82 -> 84 - Improved because `autoSummarize` gating, docs, and Server hook coverage now exist, but the TransportService evidence surface is still weak.
- `[CONTENT_COMPLETENESS]`: 50 -> 75 - Documentation and `@summary` coverage improved; deduction remains for missing config-gate documentation and overstated PR evidence.
- `[EXECUTION_QUALITY]`: 40 -> 55 - Targeted specs pass and CodeQL is green, but the whitespace gate fails and the claimed integration test does not test the implementation path.
- `[PRODUCTIVITY]`: 55 -> 70 - Most #10726 work is now present, but closeout is still blocked by evidence and docs drift.
- `[IMPACT]`: unchanged from prior review - Same shared Memory Core lifecycle impact.
- `[COMPLEXITY]`: 35 -> 45 - The follow-up added docs/tests and a lifecycle guard, broadening review surface modestly.
- `[EFFORT_PROFILE]`: unchanged from prior review - Still a Quick Win once the remaining gates are closed.

### Required Actions
To proceed with merging, please address the following:

- [ ] Remove the trailing whitespace in `test/playwright/unit/ai/mcp/server/shared/services/TransportService.spec.mjs` and rerun `git diff --check origin/dev...HEAD`.
- [ ] Replace or upgrade `TransportService.spec.mjs` so it exercises the actual implementation path instead of duplicating the `onsessionclosed` callback body locally. The test should fail if `TransportService.mjs` stops passing `onsessionclosed` to `StreamableHTTPServerTransport` or stops calling `server.onSessionClosed(id)`.
- [ ] Update `SharedDeployment.md` and the PR body to state the `autoSummarize` gate explicitly, or remove the gate if disconnect-triggered summarization is intended to be unconditional.

## PR #10731 Follow-Up Review

Status: Request Changes
Cycle: Cycle 4 follow-up on head `617f01672e8dad5ee76e5ff726ea1c28aa5fbcf6`

### Strategic-Fit Decision
- Decision: Request Changes
- Rationale: The substantive Cycle 3 concerns are mostly addressed: the transport test now exercises the real HTTP lifecycle, docs mention `autoSummarize`, targeted specs pass, and CodeQL is green. Approval is still blocked by the hard whitespace gate and by new unrelated diff surface that appeared in this force-updated head.

### Prior Review Anchor
- PR: #10731
- Target Issue: #10726
- Prior Review: https://github.com/neomjs/neo/pull/10731#pullrequestreview-4224209100
- Author Response: A2A `MESSAGE:c7aea74f-9296-4fd7-adca-40ae097e5b64`
- Latest Head SHA: `617f01672`

### Delta Scope
- Files changed: `Server.mjs`, `SessionService.mjs`, `TransportService.mjs`, `SharedDeployment.md`, `Server.spec.mjs`, `TransportService.spec.mjs`, plus newly visible `openapi.yaml` and `RequestContextService.mjs` deltas.
- PR body / close-target changes: pass for #10726 framing; it now mentions the `autoSummarize` gate and L3 transport evidence.
- Branch freshness / merge state: GitHub reports `mergeStateStatus: CLEAN`; CodeQL checks are SUCCESS.

### Previous Required Actions Audit
- Still open: whitespace gate. `git diff --check origin/dev...HEAD` still fails in `test/playwright/unit/ai/mcp/server/shared/services/TransportService.spec.mjs` at lines 25, 53, 54, 55, 75, and 87.
- Addressed: `TransportService.spec.mjs` now uses actual HTTP `POST` / `DELETE` against `TransportService.setup()`, so it exercises the production `StreamableHTTPServerTransport` lifecycle instead of duplicating the callback body.
- Addressed: `SharedDeployment.md` and the PR body now state that disconnect-triggered summarization is gated by `autoSummarize`.

### Delta Depth Floor
Delta challenge: This head introduces unrelated `openapi.yaml` and `RequestContextService.mjs` documentation deltas. They look like session-contract cleanup from a different review cycle, not #10726 disconnect summarization wiring. Keep #10726 narrow unless there is a concrete reason these are required by this PR.

### Test-Execution Audit
- `npm run test-unit -- test/playwright/unit/ai/mcp/server/shared/services/TransportService.spec.mjs` failed inside the sandbox with `TypeError: fetch failed`, then passed 1/1 outside the sandbox.
- `npm run test-unit -- test/playwright/unit/ai/mcp/server/memory-core/Server.spec.mjs` passed 4/4.
- `npm run test-unit -- test/playwright/unit/ai/mcp/server/memory-core/SessionService.spec.mjs` passed 1/1.
- Hard gate: `git diff --check origin/dev...HEAD` failed, so local validation remains red.

### Contract Completeness Audit
- #10726 disconnect contract: pass after the docs/body/test updates.
- New unrelated OpenAPI/request-context deltas: not covered by #10726 Contract Ledger or PR body. They should be removed from this branch unless intentionally included with explicit scope rationale.

### MCP-Tool-Description Budget Audit
- Triggered because `ai/mcp/server/memory-core/openapi.yaml` is now touched. No budget bloat observed in the modified descriptions, but the change is out-of-scope for #10726 and should not ride along silently.

### Metrics Delta
- `[ARCH_ALIGNMENT]`: 84 -> 88 - Improved because the transport test now exercises the real HTTP lifecycle and the `autoSummarize` gate is documented.
- `[CONTENT_COMPLETENESS]`: 75 -> 82 - Improved PR body/docs alignment; deduction remains for unrelated undocumented scope in OpenAPI/request-context deltas.
- `[EXECUTION_QUALITY]`: 55 -> 70 - Targeted behavioral tests pass and CodeQL is green; deduction remains because `git diff --check` still fails.
- `[PRODUCTIVITY]`: 70 -> 82 - #10726 core goals now look materially satisfied, but merge-readiness is blocked by mechanical cleanup and branch-scope hygiene.
- `[IMPACT]`: unchanged from prior review - Same shared Memory Core lifecycle impact.
- `[COMPLEXITY]`: 45 -> 50 - Slightly broader due the real HTTP test and extra unrelated doc surfaces.
- `[EFFORT_PROFILE]`: unchanged from prior review - Still a Quick Win once the remaining gates are closed.

### Required Actions
To proceed with merging, please address the following:

- [ ] Remove trailing whitespace in `test/playwright/unit/ai/mcp/server/shared/services/TransportService.spec.mjs` and rerun `git diff --check origin/dev...HEAD`.
- [ ] Remove the unrelated `openapi.yaml` and `RequestContextService.mjs` deltas from this #10726 branch, or explicitly justify why they are required for disconnect-triggered summarization and update the PR body accordingly.

No agent merge authority: once these are resolved and review state changes, this is still only eligible for human merge.

## PR #10731 Follow-Up Review

Status: Approved
Cycle: Cycle 5 follow-up on head `12eaeef0bc31eff8609de664f7b1e914a643e8c0`

### Strategic-Fit Decision
- Decision: Approve
- Rationale: The remaining hard-gate and scope-hygiene blockers from Cycle 4 are resolved. The PR now delivers the #10726 disconnect-triggered summarization wiring with docs, JSDoc, and focused runtime-path coverage.

### Prior Review Anchor
- PR: #10731
- Target Issue: #10726
- Prior Review: https://github.com/neomjs/neo/pull/10731#pullrequestreview-4224256260
- Author Response: A2A `MESSAGE:58f6d7b4-aef2-460a-b805-c0372b8f5510`
- Latest Head SHA: `12eaeef0`

### Delta Scope
- Files changed: six scoped #10726 files only: `Server.mjs`, `SessionService.mjs`, `TransportService.mjs`, `SharedDeployment.md`, `Server.spec.mjs`, `TransportService.spec.mjs`.
- PR body / close-target changes: aligned with the `autoSummarize`-gated disconnect behavior and L3 transport evidence.
- Branch freshness / merge state: GitHub reports `mergeStateStatus: CLEAN`; CodeQL checks are SUCCESS.

### Previous Required Actions Audit
- Addressed: trailing whitespace removed. `git diff --check origin/dev...HEAD` passes.
- Addressed: unrelated `openapi.yaml` and `RequestContextService.mjs` deltas removed from the branch.
- Previously addressed and reverified: transport-path test exercises actual HTTP `POST` / `DELETE`; docs and PR body mention `autoSummarize`.

### Delta Depth Floor
Documented delta search: I actively checked the prior whitespace blocker, the PR file scope against #10726, the PR body / close-target evidence language, and the targeted test/CI state. No remaining concerns found.

### Test-Execution Audit
- `git diff --check origin/dev...HEAD` passed.
- `npm run test-unit -- test/playwright/unit/ai/mcp/server/shared/services/TransportService.spec.mjs` passed 1/1 outside sandbox. The same test is localhost-dependent and previously failed inside sandbox with `fetch failed`, so the outside-sandbox rerun is the authoritative check.
- `npm run test-unit -- test/playwright/unit/ai/mcp/server/memory-core/Server.spec.mjs` passed 4/4.
- `npm run test-unit -- test/playwright/unit/ai/mcp/server/memory-core/SessionService.spec.mjs` passed 1/1.
- CodeQL checks are SUCCESS.

### Contract Completeness Audit
- Pass. #10726 Contract Ledger requires disconnect-triggered summarization docs and L3 integration evidence. The PR now includes `SharedDeployment.md` documentation and an HTTP-lifecycle transport test exercising `onsessionclosed`.

### Metrics Delta
- `[ARCH_ALIGNMENT]`: 88 -> 92 - Improved because the final branch is scoped, config-gated behavior is documented, and the transport lifecycle is covered through the actual HTTP path.
- `[CONTENT_COMPLETENESS]`: 82 -> 92 - Improved because the PR body, docs, and JSDoc now align; remaining deduction is only for compact rather than exhaustive docs on edge behavior.
- `[EXECUTION_QUALITY]`: 70 -> 90 - Improved because diff-check, targeted specs, and CI are green. Deduction remains for the localhost-dependent test requiring outside-sandbox verification.
- `[PRODUCTIVITY]`: 82 -> 95 - The #10726 goal is satisfied without re-architecting #10693 coordinator internals.
- `[IMPACT]`: unchanged from prior review - Shared Memory Core lifecycle improvement.
- `[COMPLEXITY]`: 50 -> 45 - Scope is back to the intended six files after removing unrelated deltas.
- `[EFFORT_PROFILE]`: unchanged from prior review - Quick Win.

### Required Actions
No required actions — eligible for human merge.

No agent merge authority: approval means human merge eligibility only.
