Purpose

vibe 1.0.76 covers the two lessons-ledger entries added after #332 was scoped. This branch is stacked on #332 (fix/vibe-lessons-20261021c), which is stacked on #331, and it is retargeted as those merge. Each lesson got a check inside the plugin first; prose only points at the check. No test here sends a signal, and every run happened on a second machine in a throwaway copy.

Rung table

Ledger entry	Rung	Check	Prose
Storybook storyFinished reports success when a play throws	helper + evidence gate	story-play-verdict.mjs judges each play from recorded channel events: PASS only when a completion was observed and no exception or error event fired; storyFinished's status is never read. The PR evidence gate needs playVerdicts, all PASS, on the storybook-plays run. The test runs a deliberately throwing play through a fake channel that reports storyFinished: success, and the verdict is FAIL	verify worker: one sentence
A fix scoped to one host of a shared component regressed the other hosts	diff rule + evidence gate	shared-consumers.mjs: a changed UI component that two or more non-test files import makes every test and story file covering it or a host a required run. When the change reads a flag, each run is needed with the flag on and off (flagStates; testRuns entries carry flag), and shared-flag-branch blocks until the change log records the host the behavior is keyed on	verify worker: one sentence

Closeout per class

• Play verdicts: the plugin had no story-sweep helper, so the helper is new, with a recorder script to inject before the story loads. It is wired where plays are recorded (the verify worker) and where they are enforced (the evidence gate). One existing evidence fixture gained playVerdicts on its storybook-plays run, and its assertion is unchanged. A new assertion covers the missing case.
• Shared component hosts: the ledger suggested that the push script refuse. In vibe, redeploy pushes come before any test run by design, so the refusal sits at the pull-request evidence gate, which runs on every PR open and update. The diff rules' importer lookup now returns importer lists (importersOf), and the existing importerCounts is derived from it, so there is no second grep.

Ledger entries

Taken: both entries. Skipped: none.

Commands run

All on the second machine, in a throwaway copy: node --test over every plugins/**/*.test.{mjs,cjs,js}, uv run pytest plugins/, uv run ruff check . and uv run pyright. Node 651 of 651, pytest 2554 passed, ruff and pyright clean. tools/vibe-workers is unchanged.
