 Next: P3 — HookCtx + ctx-hook signatures everywhere.
+
+## 2026-06-10 P3 — uniform ctx hook convention (branch fd02d9f)
+
+HookCtx frozen dataclass + hook_ctx() constructor in harness/meta.py; ctx.deps read straight from
+$CCCI_DEPS_FILE (json, both shapes) — meta.py stays import-cycle-free (deps.py imports lifecycle
+which imports meta). Registry keys carry hook_params; meta.load() enforces the expected positional
+names per hook key (READY_PROBE/BACKUP_VERIFY/EXTRA_ENV/UPGRADE_EXTRA_ENV=(ctx,),
+SCREENSHOT=(page, ctx)); _run_pre_hook applies meta.check_hook_signature(fn, ("ctx",)) to ops.py
+hooks before calling. Conversion of 17 ops.py + 8 recipe_meta hooks was scripted (def-line regex +
+bare `domain` -> `ctx.domain` inside the pre_*/hook function bodies only) and diff-reviewed; the
+only manual fixes: keycloak pre_restore passed `meta` -> `ctx.meta`, and two comment lines in
+lasuite-drive/-meet metas that the regex over-replaced were restored. wait_ready_probes gained
+op= (install/upgrade call sites pass it) so probes can know the phase.
+
+Verified on cc-ci: cc-ci-run -m pytest tests/unit -q -> 180 passed; lint PASS.
+
+Next: P4 — discovery placement rule + op_state/deps fixtures + migrate hand-parsers.
