ACTIVITY-WP-0032-T02 / ACT-ADR-006. ops_runs grows harness_profile_ref (text,
indexed) and execution_refs (jsonb), migration 0008, threaded through the
emission path, queue projection, and run artefacts.
The important part is the enforcement, not the columns. ACT-ADR-006 says
approach_hint must never override, synthesize, or fall back from an absent or
invalid harness_profile_ref — a silent fallback would reintroduce the
claim-time routing failure of 2026-08-17. resolve_execution_selector never
consults the hint: a malformed ref raises even when a hint is present, and
ACTIVITY_CORE_REQUIRE_HARNESS_PROFILE turns an absent ref into an error once
definitions have migrated.
Validation is structural only, since the glas-harness catalogue is
authoritative and must not be mirrored. Requiring the <id>@<version> pin is
worth doing locally: GlasProfiles.resolve matches an unpinned ref against every
version and refuses it as ambiguous, so the pin converts a late failure into an
emission-time error without knowing any profile id.
Migration verified on real PostgreSQL 16: upgrade, downgrade, re-upgrade, and a
legacy-shaped row still inserts and stays claimable.
