The plan pinned strict_min_version to 112.0 for the ES-module background
floor, but the existing data_collection_permissions key requires Firefox
140 desktop / 142 Android, so addons-linter warned and warningsAsErrors
failed the build. Measured: 112.0 -> 2 warnings, 140.0 -> 1, 142.0 ->
clean, omitted -> clean. 142.0 was rejected because it locks out ESR 140.
Omitting excludes nobody and degrades gracefully below 112.
Also syncs the plan's background.js block with the rejection guards added
in 22fc754, and reworks two of those comments for clarity.
Five tasks, each ending in an independently testable deliverable: tooling
plus settings validation, the pure URL builder, manifest and background
wiring, the options panel, then docs and release metadata.
Complete code for every file, 27 unit tests written out in full, and exact
commands with expected output. Global Constraints carries the spec's
verified values verbatim -- the exact permission set, strict_min_version
112.0, MAX_URL_CHARS 8000, and the copy rules that keep user-facing text
honest about ChatGPT only prefilling.
Records the traps verification found so an implementer cannot walk into
them: executeScript resolving silently to [null] on parent-process about:
pages, commands.getAll() reporting a shortcut registered when Firefox has
overridden it, and node --test exiting 0 with zero tests discovered.
Closes with an out-of-scope list so a well-meaning implementer does not
re-add auto-submit or omnibox, and a pre-PR reminder about the open AMO
data-collection question.
