+# Builder thread — bugfix-1431
+
+## Issue #1431 — phaseArtifactVerb missing verify-approval gate mapping
+
+Stream Deck's `phaseArtifactVerb` (apps/streamdeck/src/actions.ts:327) maps the
+`spec-approval`, `plan-approval`, `dev-approval`, and `pr` gates but not
+`verify-approval`. A builder blocked at `verify-approval` therefore returns
+`undefined`, and the Builder Action Automatic press falls back to `open-terminal`
+instead of opening the review diff. Meanwhile the #1428 faces already render this
+gate (yellow + `verified` glyph + `Verify` label) — so the key looks gate-blocked
+but the press opens a terminal: a face/behaviour contradiction.
+
+## Root cause (investigate phase — no code)
+
+Single missing branch in the gate section of `phaseArtifactVerb`. The VS Code
+sidebar's `gateIconFor` (apps/vscode/src/views/builder-row.ts) already knows
+`verify-approval` → `verified`; the Stream Deck resolver never caught up.
+
+## Fix (architect-scoped: strictly one line + one test + one comment cleanup)
+
+1. actions.ts `phaseArtifactVerb` gate branch: add `verify-approval` returning
+   `'view-diff'` (same as dev-approval/pr — human reviewing finished work). The
+   Automatic press then resolves view-diff → open-diff-first via
+   BuilderAction.resolveVerb (#1414), which is correct and intended.
+2. actions.test.ts: assertion beside the existing dev-approval/pr gate cases.
+3. face.ts ~line 52: delete the doc-comment clause saying the resolver "doesn't
+   handle it yet (that gap is BUGFIX #1431)" — this lane closes that gap.
+
+Do NOT touch anything else in face.ts/actions.ts (#1410 just landed a large change;
+keep this diff trivially reviewable).
+
+## Fix phase — done
+
+Made the three scoped edits. Regression test confirmed to fail without the fix
+(returns `undefined`) and pass with it (`view-diff`). Full suite 125/125,
+check-types clean, esbuild build clean (after building the `@cluesmith/codev-sdk`
+workspace dep first — the type/build errors before that were the unbuilt dep, not
+my change). Committed as `Fix #1431: ...`.
+
+## PR phase
+
+PR #1442 opened (Fixes #1431). CMAP consult needs `--project-id bugfix-1431` —
+auto-detect fails because the worktree's `codev/projects/` holds every project.
+Running all three (gemini/codex/claude) in the background.
+
+## CMAP verdicts
+
+- gemini = APPROVE (HIGH) — "clean, minimal fix … with unit test coverage."
+- claude = APPROVE (HIGH) — "correct one-line gate mapping … backed by a genuine
+  regression test; scope and hygiene are clean."
+- codex  = UNAVAILABLE — the codex lane errored on OpenAI billing ("no credits
+  remaining"), not a review verdict. Environment issue, unrelated to this change.
+
+Two independent APPROVEs, no requested changes. Notifying architect and firing the
+pr gate; codex reported honestly as unavailable rather than a fabricated verdict.
+
+## Architect review of PR #1442 (compensating for codex being down)
+
+Flagged a real gap: the fix has a second behavioural effect neither the issue nor
+my tests covered — `reviewMode()` derives from `phaseArtifactVerb` (`view-diff` →
+`diff`), so a verify-approval-blocked builder's review dials flip from `none`
+(dead) to `diff` (navigating the diff). Correct and desirable (symmetric with
+dev-approval/pr), but was untested + undocumented. Added a `reviewMode` assertion
+beside the dev-approval/pr cases and documented the dial-mode consequence in the PR
+body. 125/125 pass. Still exactly in scope. Holding at the pr gate.
