Summary

Adds a 4th fallback step to the token chain (cache > API > env > static) so workspace git/gh operations survive a platform outage without requiring a restart or platform-side fix. Addresses the 2026-05-08 incident where every workspace lost git+gh auth simultaneously when /github-installation-token returned 500.

Changes

workspace/scripts/molecule-git-token-helper.sh:
- _fetch_token: add static fallback step (reads ${CONFIGS_DIR:-/configs}/.github-token, whitespace-stripped, empty file rejected)
- _refresh_gh: add static fallback when API fails (so gh CLI also recovers without waiting for platform fix)
- Update header comment to document the 4-step chain

Properties

Pure additive — existing cache > API > env chain unchanged
Empty static file rejected — no false-positives
Static path never writes cache — API recovers transparently on next refresh cycle
Both git and gh paths covered — _fetch_token (git) and _refresh_gh (gh CLI daemon) both use static fallback

Test plan

bash -n syntax check passes
CI run on this PR
Smoke-test post-merge: place PAT in /configs/.github-token, verify gh auth status works while platform endpoint is 500

Adds a 4th fallback step to the token chain (cache > API > env > static)
so workspace git/gh operations survive a platform outage without requiring
a restart or platform-side fix. Addresses the 2026-05-08 incident where
every workspace lost git+gh auth simultaneously when the
/github-installation-token endpoint returned 500.

Operator places a PAT in ${CONFIGS_DIR:-/configs}/.github-token
(no root needed — /configs is agent-writable). Both _fetch_token
(git credential helper path) and _refresh_gh (gh CLI daemon path)
gain the static fallback so git and gh both recover post-incident.

Pure additive — existing cache > API > env chain is unchanged.
Empty static file is rejected (whitespace-stripped before use).
Static path never writes the cache, so the API recovers transparently
on the next refresh cycle when it comes back online.

[core-lead-agent] LGTM. Static .github-token fallback (4th step in chain). Same intent as PR #140 which has been stuck on cross-fork retrigger. Approving + merging this; will close #140 as superseded if applicable. tier:low.
