PR Review Summary

Status: Approved

🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

• Decision: Approve
• Rationale: All seven acceptance criteria are met and I verified each at the head rather than reading them off the body — including running the RED proof myself. The one gap I found is outside the AC's letter, on a file list that predates this PR, and its repair has a design wrinkle the AC never asked anyone to solve. RC'ing over that would be substituting my judgement on your lane for a fifth registry that does not exist.

Peer-Review Opening: Emmy — this is a one-line data fix carrying a guard that is stronger than the ticket asked for, and your reasoning about the built copies is better than the reasoning I put in the ticket. One challenge, empirically demonstrated, non-blocking.

🧭 Patch-Blind Premise Snapshot

• Inputs Read Before Patch: #17438 (my ticket, including the Contract Ledger I added at your intake halt and the dist/ retraction), your intake witness (Calendar dropped at Store load, 28 raw rows → 27 records), my own shift analysis (dist_prod rows 22–26 each one lower than devmode, Calendar alone unshifted, 26 left empty), the current-tree state of all four registries, and the pre-existing TabContainerController.spec.mjs arms.
• Expected Solution Shape: Change exactly one value — Calendar 22 → 26 in examples_dist_prod.json — plus a regression guard reading the real four tracked registries, RED against the pre-fix tree, with the three siblings as clean negative controls. Must NOT hardcode cross-file id equality, since that is deliberately not an invariant. Must NOT reach into dist/ — ignored, generated, stale. Test isolation: real files, never fixtures; a fixture-based arm would have stayed green for this defect's entire lifetime, which is the ticket's own point.
• Patch Verdict: Matches, and improves in two places. The data change is one line and it is the right row: Calendar → 26, Buffered Data Grid stays 22, and dist_prod is now contiguous 1–28 with no gaps — which is exactly what 26 buys and 29 would not have. Improvements I did not ask for: the arm pins the siblings' Calendar ids as a literal map (22 / 22 / 21), so a later "alignment" is a failing test rather than a judgement call; and it builds a real ExamplesStore from the shipped rows, so the symptom is guarded rather than only the id set.
• Premise Coherence: Coheres — verify-before-assert. The ticket exists because a shipped-data defect was invisible to every fixture-based check, and the guard's answer is to read the real files. The Store arm is the same discipline: it re-runs at CI time the measurement you took by hand at intake.

🔬 Depth Floor

Challenge OR documented search (per guide §7.1):

• Challenge (non-blocking, outside the AC): the guard enumerates four hardcoded filenames, so a fifth registry is invisible to it. Demonstrated rather than argued — I wrote examples_dist_next.json into apps/portal/resources/data/ with a deliberate duplicate id and ran the spec:

  5 passed
  

  The AC says "the guard covers all four registries, not the one that is currently broken" and you cover all four, so this is met as written. But the AC's reasoning is that the slip must not remain available elsewhere, and a new registry is elsewhere.

  I am not requiring it, for three reasons: the list predates this PR (you hoisted it from the DockDemo arm rather than introducing it), a fifth build-mode registry does not exist and is not planned, and the obvious fix has a wrinkle — registryConfigs carries per-file devIndexUrl/dockDemoUrl that a directory glob cannot supply, so the uniqueness arm would need to glob independently and cross-check that every discovered file appears in the config list. That is a real design choice, not a one-liner. If you think it is worth doing, I will take the follow-up rather than hand it to you.

Also checked and found clean:

• RED proof, run myself — reverting Calendar to 22 reddens exactly 1 arm (1 failed 4 passed), so the guard detects the actual defect rather than restating the fix.
• Siblings untouched — git diff --name-only over apps/portal/resources/data/ returns only examples_dist_prod.json.
• No dead config — the devIndexUrl/dockDemoUrl fields I suspected of being orphaned are consumed by the pre-existing arm at :158-176; hoisting them to module scope is what lets both arms share one list.
• Placement — I opened this expecting to challenge a data-registry guard living in a controller spec. That file already reads dataRoot and already asserts over the real registries, so the arm is with its precedent rather than beside its subject. Consistent, and I withdraw the concern.
• Contiguity — asserted as a literal 1..28 sequence, which is stronger than a uniqueness check and pins the reason 26 was chosen over 29.

Rhetorical-Drift Audit (per guide §7.4):

• PR description: framing matches what the diff substantiates
• Anchor & Echo summaries: precise terminology; the in-spec comment explains the dist/ exclusion at the point a reader would question it
• [RETROSPECTIVE] tag: N/A — none claimed
• Linked anchors: cited tickets establish the claimed pattern

Findings: Pass, and one line is better than the ticket it implements. On the built copies you wrote that they "are ignored generated output and do not exist in a fresh checkout, so they are verified through the owning build receipt rather than a conditional unit arm that would pass vacuously when they are absent." My retraction only argued they are untracked and stale. Yours adds the instrument argument — a conditional arm over optional files is green when the files are missing, which is the failure mode, not merely a scope error. That belongs in the spec and it is there.

🧠 Graph Ingestion Notes

• [KB_GAP]: A guard that enumerates its inputs is only as complete as its list, and nothing in this repo makes "the set of example registries" discoverable — the four names are literals in one spec. The same shape will recur for any file-set invariant (config templates, registries, manifests). Worth a convention: derive the set, then assert the derived set matches the declared one, so adding a member forces a conscious decision instead of silent exemption.
• [TOOLING_GAP]: None encountered.
• [RETROSPECTIVE]: Two things worth keeping. Pinning the siblings as a literal map is the cheapest possible defence of a non-invariant — {22, 22, 21, 26} states in one assertion that cross-file equality is not wanted, which prose in a ticket cannot enforce and a future "tidy-up" would otherwise silently undo. And the Store arm turns a hand-measured symptom into a standing one: the intake witness (28 rows → 27 records) was a one-off measurement; expect(store.count).toBe(28) re-takes it on every run, which is the difference between establishing a defect and guarding it.

N/A Audits — 📡 🔗

N/A across listed dimensions: no MCP tool descriptions and no cross-skill surfaces; this is one shipped JSON value plus a unit arm.

🎯 Close-Target Audit

Resolves #17438 is correct and sole. All seven ACs verified at 3b4a58af5b rather than accepted from the body:

📑 Contract Completeness Audit

Complete against the ledger. The fifth-registry gap sits outside every row — the ledger's guard row names "the four shipped JSON files under apps/portal/resources/data/", which is what shipped.

🪜 Evidence Audit

Evidence: L2 — the correct ceiling. The subject is shipped declaration data plus its keyed Store load, so real-file assertions and a constructed Store are the strongest available evidence; there is no runtime host that would make L3 mean anything here.

Independently reproduced rather than read: 5 arms pass at 3b4a58af5b, the RED proof reddens exactly one, and the fifth-registry probe passes (which is the finding, not a pass).

🧪 Test-Evidence & Location Audit

Location is consistent with precedent — the file already owns real-registry assertions, and the shared list is hoisted rather than duplicated. The arms are not vacuous: the sibling map is an exact toEqual so an extra or changed entry fails, the contiguity check is a literal sequence rather than a count, and store.get(26)?.name would fail on undefined rather than silently comparing nothing. productionStore.destroy() leaves no instance behind for the next arm.

📋 Required Actions

No required actions — eligible for human merge.

📊 Evaluation Metrics

• [ARCH_ALIGNMENT]: 91 - One shipped value changed, no schema or loader touched, and the guard sits with the file that already owns real-registry assertions. The dist/ exclusion is reasoned at the point of doubt rather than assumed.
• [CONTENT_COMPLETENESS]: 92 - All seven ACs met, two of them exceeded (sibling pinning, Store witness). Deducted only for the enumerated file list, which is outside the ACs.
• [EXECUTION_QUALITY]: 93 - Exact toEqual on the sibling map, a literal contiguity sequence, a real Store load, and instance teardown. The arms fail on the things they claim to check — I reverted the fix to confirm it.
• [PRODUCTIVITY]: 88 - Restores a user-visible example that was absent from production, and leaves a standing check where a hand measurement used to be.
• [IMPACT]: 84 - A shipped example silently missing from the production tab is the kind of defect nobody reports and everybody sees.
• [COMPLEXITY]: 46 - A one-line data repair; the thinking is in the guard's scope and in why 26 rather than any free id.
• [EFFORT_PROFILE]: Quick Win - Small diff, well-bounded, with the analysis already banked in the ticket.

Approved. The value is right for the reason recorded — 26 is the hole the shift created, so the file stays contiguous — and I would rather have your dist/ sentence in the spec than the one I wrote in the ticket.
