harness.meta.HookCtx (frozen): .domain, .base_url, .meta (RecipeMeta), .deps
(provisioned dep creds from $CCCI_DEPS_FILE or None), .op (current lifecycle op
or None); built via meta.hook_ctx() at each hook call site.
All recipe callables now take ctx: EXTRA_ENV(ctx), UPGRADE_EXTRA_ENV(ctx),
READY_PROBE(ctx), BACKUP_VERIFY(ctx), SCREENSHOT(page, ctx), ops.py pre_<op>(ctx).
Dict-valued EXTRA_ENV/UPGRADE_EXTRA_ENV unchanged (only the callable signature
moved). Call sites converted: deploy_app env shaping, perform_upgrade,
wait_ready_probes (gains op=), _perform_op BACKUP_VERIFY, screenshot.capture,
_run_pre_hook.
Legacy signatures fail FAST with a clear migration message: the registry carries
hook_params per hook key, enforced at meta.load() (MetaError names the old vs new
signature); ops.py pre-op hooks get the same check at the orchestrator call site
(meta.check_hook_signature) — no silent TypeError mid-run.
Migrated every in-repo user mechanically (17 ops.py files; cryptpad/lasuite-*/
mailu EXTRA_ENV; mumble+lasuite-drive READY_PROBE; ghost/discourse BACKUP_VERIFY)
— seeded values, probes and assertions byte-identical (domain -> ctx.domain;
keycloak pre_restore's meta arg -> ctx.meta).
Unit tests: hook_ctx field contract, ctx.deps from the run deps file, legacy-
signature MetaError (READY_PROBE/EXTRA_ENV/SCREENSHOT + pre-op checker), ctx
signatures accepted. Docs table regenerated (signature docs in key docs).
Verified on cc-ci: cc-ci-run -m pytest tests/unit -q -> 180 passed; scripts/lint.sh -> PASS.
9-service stack (frontend/backend/celery/y-provider/docspec/postgres/redis/minio/nginx) converges
9/9 and serves the SPA; install 2 passed on host. Root-caused a deploy timeout: cold-pulling ~9
large images exceeds abra's default 300s convergence TIMEOUT -> bumped to 900 via EXTRA_ENV (the
generic per-recipe mechanism, no harness surgery). upgrade/backup use a postgres marker (docs/docs)
exercising the pg_backup.sh DB-dump hook; verifying next.
