abra rejects env-interpolation in healthcheck start_period (FATA 'Does not match
format duration' for both ${VAR} and quoted forms — validates the literal compose
duration before .env substitution). So §9 pt1's env-var route is impossible for
this field; the §9-compliant fix is a LITERAL start_period:20m bump in the
recipe-PR (recipe everyone runs, not a cc-ci overlay; strictly safer). Remove
APP_START_PERIOD from recipe_meta EXTRA_ENV; record the finding in DECISIONS
(ghost E1 must use the same approach); STATUS-2 → new PR head 7a2e0e0.
