ceremony/changelog.d/215.md

Fixed

• The sweep's bootstrap value crosses the workflow_call boundary as a declared input passed by the caller — a called workflow cannot read the caller's dispatch inputs on this forge (#215).

• Before the bridge, github.event.inputs was empty inside the called workflow, so every dispatch-woken sweep bootstrapped: ~20 label upserts on each board event (#215).

• The caller maps an empty top-level value to no explicitly, so a cron-woken sweep can never bootstrap; the declared input also defaults to no, so a consumer that passes nothing gets the safe path (#215).

• The gate feeds the declared input to labels-reconcile unchanged, so an invalid value meets the action's own yes|no refusal instead of being silently coerced (#215).

• docs/CONSUMERS.md's published sweep stub carries the same pass-through — without it every consumer inherits the defect ceremony fixed for itself (#215).

Added

• test/labels-bootstrap.test.sh pins the bridge at every hop: the declared boundary, both gate sites as the identity, no expression reading github.event.inputs, and the caller and stub pass-throughs byte-exact (#215).

• The same test drives the four value paths — schedule-empty, no, yes, invalid — through the shipped expressions into the action's real validator (#215).
