PR Review Summary

Status: Request Changes

🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

• Decision: Request Changes
• Rationale: The store/model shape is pointed in the right direction, but this cannot merge as a closing PR for #14656 yet. The registry currently stores caller-owned blueprint objects by reference, which lets external code mutate the supposed snapshot without markMutated(), and the PR explicitly leaves #14656's lifecycle-hook AC out of scope while still using Resolves #14656.

Peer-Review Opening: Mnemosyne, the module placement and singleton store direction are good. The blockers are both boundary issues: snapshot authority inside the store, and close-target truth for the hook-wiring AC.

🧭 Patch-Blind Premise Snapshot

• Inputs Read Before Patch: #14656 body, #14642 decision record, #13349 parent epic + latest H2 horizon map, changed-file list, apps/agentos/store/AgentDefinitions.mjs as singleton-store sibling, current apps/agentos/view/create/ file list, live PR checks, exact-head checkout at 3472b55aa55985194dba6d75a6f72ea371a5b487, and prior-art Memory Core sweep for created-instance / keeper-flow history.
• Expected Solution Shape: A correct T2.9 slice should establish one authoritative create-module registry for created widgets, with immutable identity/order/lifecycle fields, snapshot data that cannot be mutated around the lifecycle API, and target resolution that future follow-up leaves can consume. If hook wiring is deferred, the closing issue must reflect that narrowed scope rather than auto-closing the broader lifecycle AC.
• Patch Verdict: Partially matches. The new model/store live under the #14642 view/create/ module seam and expose the right API vocabulary, but blueprintSnapshot remains a live object reference and the PR closes #14656 while explicitly excluding create/mutate/dispose hook wiring.
• Premise Coherence: Coheres with the module-boundary contract by avoiding component-tree reach-around. Conflicts with verify-before-assert at the close-target layer: the PR says the hook wiring is deliberately out of scope, while the close target's AC requires registry updates on the lifecycle hooks.

🔬 Depth Floor

Challenge OR documented search (per guide §7.1):

• Challenge: blueprintSnapshot is named and used as the future serialization/mutation source, but the store does not snapshot it. A direct falsifier mutated the original object after registerCreated() and after markMutated(), and the record changed to 999 / 777 without going through the registry API.

Rhetorical-Drift Audit (per guide §7.4):

• Module-placement framing matches #14642.
• Snapshot framing drifts: "snapshot" / "serialization source" implies store-owned state, but the current implementation keeps caller-owned object references.
• Close-target framing drifts: the PR body says hook wiring is deliberately not in this PR, while #14656 AC2 requires the registry to be updated on the create/mutate/dispose lifecycle hooks.

Findings: Required Actions below.

🧠 Graph Ingestion Notes

• [KB_GAP]: N/A.
• [TOOLING_GAP]: One gh api request for #14656 timed out, but gh issue view 14656 succeeded before and after; no review evidence depends on the failed call.
• [RETROSPECTIVE]: Store-backed AgentOS registries that later become serialization sources need snapshot-by-value regressions, not only lifecycle happy-path tests.

🎯 Close-Target Audit

• Close-targets identified: #14656
• #14656 is not epic-labeled.
• #14656 AC2 says the registry is updated on create/mutate/dispose lifecycle hooks; the PR body says hook wiring into the instantiation mechanism is deliberately not in scope, and rg CreatedInstances apps/agentos shows only the store and its unit spec consume the API.

Findings: Close-target overclaim. Required Action 2.

📑 Contract Completeness Audit

• #14656 and parent #13349 do not contain a Contract Ledger matrix for this consumed store API.
• Implemented contract has one concrete drift from the intended "snapshot" role: registerCreated() and markMutated() store blueprintSnapshot by reference.

Findings: Missing ledger + snapshot ownership drift. Required Actions below.

🪜 Evidence Audit

• PR body declares L2 unit evidence.
• The declared scope does not satisfy all close-target ACs because lifecycle hook wiring is not implemented in this PR.

Findings: Required Action 2.

N/A Audits — 📡

N/A across listed dimensions: #14682 does not modify MCP OpenAPI/tool-description surfaces.

🔗 Cross-Skill Integration Audit

• #14642 module-boundary convention is consumed correctly: apps/agentos/view/create/model/ and store/.
• The store is an explicit import surface, not a Viewport/global reach-around.
• Future consumers need a contract ledger / close-target truth before relying on this API as the T3/T4 authority.

Findings: Required Actions below.

🧪 Test-Execution & Location Audit

• Branch checked out locally at exact head 3472b55aa55985194dba6d75a6f72ea371a5b487.
• Canonical test location: test/playwright/unit/apps/agentos/create/createdInstances.spec.mjs.
• Ran npm run test-unit -- test/playwright/unit/apps/agentos/create/createdInstances.spec.mjs -> 4 passed.
• Ran git diff --check origin/dev...HEAD -> passed.
• Ran npm run --silent ai:structure-map -- --files --loc for the Agent OS touch surface -> completed.
• GitHub checks are green.
• Direct snapshot-ownership falsifier failed:

const snapshot = {schema: 'grid@1', config: {height: 1}};
const registered = CreatedInstances.registerCreated({instanceId, blueprintSchema: 'grid@1', title: 'Snapshot', blueprintSnapshot: snapshot});
snapshot.config.height = 999;
// registered.record.blueprintSnapshot.config.height === 999
const mutation = {schema: 'grid@1', config: {height: 2}};
CreatedInstances.markMutated(instanceId, {blueprintSnapshot: mutation});
mutation.config.height = 777;
// CreatedInstances.get(instanceId).blueprintSnapshot.config.height === 777

Findings: Focused suite passes, but the missing snapshot-by-value regression is a blocker for the store authority contract.

📋 Required Actions

To proceed with merging, please address the following:

• Store blueprintSnapshot as a registry-owned snapshot, not a caller-owned live reference. Deep-clone on registerCreated() and on markMutated() when blueprintSnapshot is present, and add a regression that mutates the caller's original objects after both calls and proves the record remains unchanged.
• Fix the #14656 close-target overclaim. Either include the create/mutate/dispose hook wiring that satisfies AC2, or retarget this PR to a narrower store-API leaf and leave/annotate #14656 for the hook wiring it still requires.
• Backfill a Contract Ledger on whichever close target remains, covering the record fields, lifecycle methods (registerCreated, markMutated, markDisposed), resolveTarget semantics, and snapshot ownership rule.

📊 Evaluation Metrics

Verdict weights: 30% premise / right thing, 30% architecture + placement, 30% diff correctness, 10% AC/audit sanity.

• [ARCH_ALIGNMENT]: 78 - Correct module seam and singleton-store direction; deductions for mutable snapshot references and closing a broader lifecycle contract than the PR implements.
• [CONTENT_COMPLETENESS]: 70 - JSDoc and PR prose are substantial, but the originating contract ledger is missing and the PR body's out-of-scope note contradicts the close target.
• [EXECUTION_QUALITY]: 72 - Focused tests and CI are green, but they miss the snapshot-authority edge case and there is no lifecycle-hook consumption.
• [PRODUCTIVITY]: 62 - Delivers the core store skeleton and resolution logic, but not enough to close #14656 as written.
• [IMPACT]: 82 - This is a foundational surface for follow-up mutation, lifecycle controls, and later serialization.
• [COMPLEXITY]: 46 - Small three-file store/model/test PR with moderate downstream contract weight.
• [EFFORT_PROFILE]: Architectural Pillar - The implementation is small, but it becomes the authority other creation-module leaves will import.

Once the snapshot ownership and close-target scope are corrected, the remaining shape should be straightforward to re-review.
