| 1 | Reviewed plan **7db8869f** against spec **9ccfaca6**, amendment **56756f09**, reviews R1–R4, dispositions, and the current code. |
| 2 | |
| 3 | | Earlier finding still open after R4 | Status | Why | |
| 4 | |---|---|---| |
| 5 | | R1-17 — release/build/scratch gates | Resolved; decline accepted | The final operator rule explicitly authorizes the socket-test arrangement. Release and cross-build gates are covered. | |
| 6 | | R4-1 — unread stored region violates R9a | Resolved | Pooled/fleet branches leave effective placement unknown; canary requires both knowledge flags. | |
| 7 | | R4-2 — refusal suggests rejected alternatives | Resolved | Alternatives use the relevant acceptance predicates, including allow-lists and R9; tests submit the advertised choices. | |
| 8 | | R4-3 — unchanged form neither preserved nor tested | Resolved | Conditional placement preserves whitespace; complete form goldens cover switch-off and one eligible region. | |

| 10 | **New finding: P1 — Task 22 discards the authoritative canary record before deciding whether to create.** |
| 11 | |
| 12 | **Plan:** [record read and return, lines 7259–7272](/home/paulca/amadan.net/carlos/platform-nearest-region/docs/superpowers/plans/2026-10-02-nearest-region-default.md:7259), [caller wiring, line 7309](/home/paulca/amadan.net/carlos/platform-nearest-region/docs/superpowers/plans/2026-10-02-nearest-region-default.md:7309). |
| 13 | **Code:** [canary.go:387](/home/paulca/amadan.net/carlos/platform-nearest-region/canary.go:387), [canary.go:405](/home/paulca/amadan.net/carlos/platform-nearest-region/canary.go:405), [provision.go:1188](/home/paulca/amadan.net/carlos/platform-nearest-region/internal/provision/provision.go:1188). |
| 14 | |
| 15 | Consider an existing UK canary preceded by 520 other records, invoked with `--region uk`. The direct GET correctly finds it and approves the matching region. But `canaryRegionCheck` returns only its hostname. The unchanged command then reads the capped list, misses that same record, and selects `canaryPlanCreate`. It attempts a duplicate create instead of reusing or rechannelling the existing canary, ultimately receiving [409 “already exists”](/home/paulca/amadan.net/carlos/platform-nearest-region/internal/console/apiinstances.go:1017). |
| 16 | |
| 17 | That violates [§11’s “equal proceeds” requirement](/home/paulca/amadan.net/carlos/platform-nearest-region/docs/superpowers/specs/2026-10-01-nearest-region-default-design.md:923). R3-1’s mismatch refusal **is fixed**; this finding concerns the successful matching-region path. Task 22’s capped-list command test exercises only refusal. |
| 18 | |
| 19 | **Fix:** carry the authoritative record and `found` result into the create/rechannel/ready decision, including the later environment-update decision. Add command tests with a same-region canary beyond the cap, covering both matching and different channels. Assert no duplicate-create request and that execution reaches shipping; these should fail against the proposed wiring. |
| 20 | |
| 21 | I found no additional blocker in migration carry through `migrateAppsKey`, publication/reconciliation parsing, create-door precedence, interface declarations, or legacy wire compatibility. `CARLOS_POOLS=",tito"` correctly publishes shared-pool eligibility as false. The C-string inventory, copy-review ordering, Review Focus cases and rollout stages have task coverage. |
| 22 | |
| 23 | The dependency choices have no identified blocker: [MaxMind v1.13.1 declares Go 1.21](https://raw.githubusercontent.com/oschwald/maxminddb-golang/v1.13.1/go.mod), compatible with this repository’s Go declaration; [IANA publishes tzdata 2026b and its signature](https://data.iana.org/time-zones/releases/). Signature verification and all five CI cross-build targets are included. |

| 25 | This was static review. I did not reproduce the author’s scratch implementation, red/green runs or cross-builds. No files changed; the worktree remains clean. |
| 26 | |
| 27 | --- |
| 28 | |
| 29 | **FIRST PROMPT:** |
| 30 | Independent, read-only round-5 review of the nearest-region implementation plan. |
| 31 | |
| 32 | **WHAT:** |
| 33 | Check earlier dispositions, spec coverage, interfaces, compatibility and execution gates. |
| 34 | |
| 35 | **STATUS:** |
| 36 | Earlier findings resolved; one new P1 in canary reuse. |
| 37 | |
| 38 | **NEEDED:** |
| 39 | No additional user input. |
| 40 | |
| 41 | **RECOMMENDED:** |
| 42 | Carry the direct-read record through Task 22 and add matching-region command tests. |
| 43 | |
| 44 | **SESSION:** |
| 45 | Safe to close; no files changed or processes left running. |
| 46 | |
| 47 | **Verdict: not ready to execute. Task 22 still fails to reuse a matching-region canary outside the capped list.** |
