Add the review-loop warning light (vision 2c, part 2) - #35
Conversation
A read-only report gives every recorded review cycle one of four states: red, amber, no warning (usefulness unknown) or not determinable. Two recorded signals decide the state: curve entries beyond the floor, and increases in Blocker + Major between passes. Product distance is read from changed files only where they establish it. The thresholds are calibrated against the 26 closed cycles on main and the field reports, and the cases the light cannot distinguish are listed as limits. Pass 1 led to Daniel narrowing the scope on 2026-10-03 (32609a0). cycle b6d8vzijb6; floor 3 per {docs/superpowers/stories/2026-10-02-review-loop-usefulness-assessment-story.md (level 1)}; hook reminder threshold absent cycle b6d8vzijb6; Gate-A spec (passes 1-6, gpt-6-astra): Findings 18,14,12,8,3,3. Blockers 0,0,0,0,0,0. Majors 12,8,7,2,2,0.

The plan embeds the tested report, its POSIX-sh suite (10 cases) and
the docs/CI edit script, plus seven rulings where it settles what the
closed spec left open.

scripts/loop-usefulness.py gives every review cycle recorded in commit bodies one of four states: red, amber, no warning (usefulness unknown) or not determinable. Two recorded signals decide the state: curve entries beyond the floor, and increases in Blocker + Major between passes. Product distance comes from changed files only where they establish it, and stored effort comes from the run-analytics store. A warning means "reassess review effort", never "waste proven". The report writes nothing. scripts/loop-usefulness.test.sh (10 cases) joins the quality and lint rows, CI and the inventories in AGENTS.md and README.md. Evidence — docs/superpowers/stories/2026-10-02-review-loop-usefulness-assessment-story.md Battery: AGENTS.md quality row, exit 0 at 56e6083b0f00b661fc58cd640b5524371e64767b. Check (counterfactual): at 3345bf7 no report exists (git ls-tree prints nothing). Negative control in the suite: a copy that ignores increases turns the four-increase fixture from red into no warning, and the suite catches it. Suite 10/10 under sh (in the quality row) and under dash. Over main at 7cbbce4: red 4, amber 1, no warning 21, as spec §5a states. cycle cp94wg3f0g; floor 3 per {docs/superpowers/stories/2026-10-02-review-loop-usefulness-assessment-story.md (level 1)}; hook reminder threshold absent cycle cp94wg3f0g; Gate B (passes 1, gpt-6-astra): Findings 0. Blockers 0. Majors 0. The single logical pass was one reviewType full call against 3335f90.../56e6083..., and both branches found nothing: the zero-finding exit.

Merge Risk: 🔵 Low · up to An unregistered hook script can make a review cycle appear to have no warning when its distance is uncertain. Correct the classification before relying on that result; the report remains read-only.

Classify hook scripts as product only when hooks.json registers them.
distance() labels any changed non-test plugins/*/hooks/*.sh file as product without checking whether a hook registration runs it. With three excess passes and no increases, that classification yields “no warning”; unknown distance yields “not determinable” because machinery thresholds produce amber. Determine hook-script product paths from hooks.json, and update the design rule to match.

Valid, and deliberately deferred: the closed spec (§4) sets this rule. Today the only hook script, codex-gate.sh, is registered, so no result changes. Daniel decided (2026-10-03) to record it in todos.md, to be fixed when a second hook script appears.

@dsnger Thanks for the clarification. The finding remains valid, but the registered codex-gate.sh means it does not change current results. I accept the decision to defer the fix until a second hook script appears.
Would you like a GitHub follow-up issue in addition to the todos.md entry?

Learning: In dsnger/dev-workflow-kit, the closed loop-usefulness specification (§4) intentionally permits path-based classification of hook scripts in scripts/loop-usefulness.py. Daniel decided on 2026-10-03 to defer registration-based classification until a second hook script appears, with the follow-up tracked in todos.md. Do not request this change again in the current PR solely because the classifier does not inspect hooks.json.

… review) scripts/loop-usefulness.py now runs every git call with --no-replace-objects and an empty graft file, as ledger-metrics.py does. A `git replace` ref or legacy graft therefore cannot change which records or paths it reads. A new suite case (11 in total) replaces a fixture commit with one whose floor differs and checks the report is unchanged. todos.md records the same pre-existing gap in run-analytics.py.
