Summary

Drops molecule-core's dead runtime_image_pins migration (mig 047) + the dead reader at handlers/runtime_image_pin.go. CP (molecule-controlplane mig 027) is the single SSOT for runtime image pins — it has the writer, reader, hard-gate (RFC internal#541 Step 2), seeded post-suspension digests, and the admin endpoints. This PR ratifies that reality.

Closes #335 (🚨 SSOT-Instance-12 — runtime_image_pins replicated across molecule-core + molecule-controlplane DBs without sync trigger).

Supersedes #1608 (silent-revert blocker)

#1608 was cut from a base before #1585 (RFC#596 Phase 2 dual-push to Gitea-PyPI primary) landed on main (commit 6602361b, 2026-05-20). Merging #1608 as-is would have silently reverted .gitea/workflows/publish-runtime.yml (-106 LoC):

• Publish to Gitea PyPI registry (PRIMARY) step — gone
• continue-on-error: true on Publish to PyPI — gone (re-restoring PyPI as a hard requirement → 2026-05-19 P0 re-arming)
• Publish job summary block — gone

Sub-agent a5521785 flagged this on PR #1608 comment 41389. Per CTO memo 2026-05-20 (reference_package_distribution_open_ecosystem_dual_push): "Our packages = open-ecosystem → dual-push Gitea + PyPI ... RFC#596 stays dual-push."

This PR is a clean rebase against current main (tip f17375a9) with the substantive Go logic of #1608 preserved + zero workflow-file delta. Verified via the API compare endpoint: diff vs main contains ONLY workspace-server/... files.

What changed

• workspace-server/migrations/20260520120000_drop_runtime_image_pins.{up,down}.sql — drop the unused table; care-zone column workspaces.runtime_image_digest + its partial index PRESERVED per RFC internal#617 §3
• workspace-server/internal/handlers/runtime_image_pin.go + runtime_image_pin_test.go — DELETED (dead reader)
• workspace-server/internal/handlers/workspace_provision.go — Image: "" instead of resolveRuntimeImage(ctx, payload.Runtime); surviving db.DB.QueryRow upgraded to QueryRowContext so ctx stays load-bearing
• workspace-server/internal/provisioner/{provisioner,registry}.go — doc comments updated to point at CP as SSOT
• workspace-server/internal/db/migration_20260520_drop_runtime_image_pins_test.go — static-file regression pin: up.sql DROPs the table, does NOT touch the care-zone column / index, and the dead reader files cannot be re-added without failing the test
• Hygiene: prune now-stranded mock.ExpectQuery("SELECT digest FROM runtime_image_pins") in handlers_test.go + workspace_provision_test.go; comment refresh in provisioner_test.go

Verification

• go vet ./internal/handlers/... ./internal/db/... ./internal/provisioner/... — clean
• go build ./... — clean
• go test ./internal/handlers/ — 16.5s, all pass
• go test ./internal/db/ -run TestMigration20260520 — 0.2s, pass
• go test ./internal/provisioner/ — 0.3s, pass
• Empirical confirmation: branch parent is current main tip f17375a9, NOT pre-#1585 stale base; .gitea/workflows/publish-runtime.yml is byte-identical to main

Tier / review

tier:medium + area:schema. Reversible via down-migration. Two-eye review: core-be (Go read path) + core-qa (migration correctness). Cascade plan to ~6 live tenant DBs per RFC internal#617 §7 + feedback_image_promote_is_not_user_live (verify on at least 2 tenants post-deploy).

Test plan

• Unit tests: handlers + db + provisioner all green locally
• CI green on Gitea Actions (publish-runtime.yml is untouched — should not re-trigger PyPI publish)
• core-be APPROVE
• core-qa APPROVE
• Post-merge: apply migration on staging tenant; confirm runtime_image_pins table dropped + workspaces.runtime_image_digest column preserved
• Post-merge: cascade to ~6 live tenants per RFC internal#617 §7

chore(workspace-server): drop dead runtime_image_pins migration (closes #335, supersedes #1608) ... 03cee314ba

Empirical finding (a6e3ff018, 2026-05-20): molecule-core's
runtime_image_pins table (mig 047) has never had a writer in any repo.
The reader at handlers/runtime_image_pin.go has been hitting
sql.ErrNoRows on every workspace provision since mig 047 landed,
silently falling through to the :latest path. CP's parallel table
(CP mig 027) is the de-facto and only SSOT — it has the writer
(POST /cp/admin/runtime-image/promote), the reader, the hard-gate
(RFC internal#541 Step 2), seeded post-suspension digests (CP mig 028),
and the admin endpoints.

This PR ratifies that reality.

Note: this is a fresh rebase against current main (tip f17375a9).
PR #1608 was cut from a base before #1585 (RFC#596 Phase 2 dual-push)
landed, so merging it would silently revert the publish-runtime.yml
Gitea-PyPI-primary path. Sub-agent a5521785 flagged this on PR #1608
comment 41389. The substantive Go logic is identical to PR #1608;
the only difference is the base.

What

- Add 20260520120000_drop_runtime_image_pins.up.sql / .down.sql to drop
  the unused table. Care zone PRESERVED: workspaces.runtime_image_digest
  column + its partial index untouched (earmarked for a future
  stale-workspace panel per RFC internal#617 §3).
- Delete handlers/runtime_image_pin.go (the dead reader) +
  handlers/runtime_image_pin_test.go.
- handlers/workspace_provision.go: replace
  resolveRuntimeImage(ctx, payload.Runtime) with Image: "" (the dead
  reader was already returning "" on every call). Rewire the
  surviving db.DB.QueryRow on this call site to QueryRowContext so
  the provision-timeout ctx stays load-bearing.
- Doc comments in provisioner/provisioner.go + provisioner/registry.go
  updated to point at CP as the SSOT instead of the dead local table.
- Add db/migration_20260520_drop_runtime_image_pins_test.go — static-
  file pin that up.sql DROPs runtime_image_pins, does NOT touch the
  care-zone column / index, and that the dead reader files cannot be
  re-added without failing the test.
- Hygiene: prune the now-stranded
  mock.ExpectQuery("SELECT digest FROM runtime_image_pins") rows in
  handlers/handlers_test.go and handlers/workspace_provision_test.go
  (the dead reader is gone, so the mock expectation can never fire).
  Provisioner test comment updated to reflect CP-as-SSOT.

Why

Two parallel-named tables with structurally incompatible schemas, only
one ever written — that is exactly the kind of internal drift
feedback_no_single_source_of_truth was written about for non-vendor
surfaces. The deletion is reversible (down.sql recreates the table)
and the only behavior change is "ctx is now propagated into the
workspace_dir DB lookup", which is a small correctness nudge.

Verification

- [x] go vet ./internal/handlers/... ./internal/db/... ./internal/provisioner/...  — clean
- [x] go build ./...  — clean
- [x] go test ./internal/handlers/ ./internal/db/ ./internal/provisioner/  — all pass (16.5s + 0.2s + 0.3s)
- [x] New regression tests assert the care-zone column is not touched + the dead reader cannot return
- [x] Empirical grep cross-check: no writer for runtime_image_pins in molecule-core; no reader for workspaces.runtime_image_digest anywhere (both confirmed in RFC internal#617 §1 + §3)
- [x] Verified clean rebase: branch parent is current main tip (f17375a9), NOT pre-#1585 stale base. Diff vs main contains ONLY the migration-drop work — no .gitea/workflows/publish-runtime.yml regression.

Tier

tier:medium + area:schema — schema/migration change. Reversible by
re-running the down-migration. Two-eye review reviewers: core-be
(read path / Go) + core-qa (migration correctness). Cascade plan to
~6 live tenant DBs per RFC internal#617 §7 +
feedback_image_promote_is_not_user_live (verify on at least 2
tenants post-deploy).

Memory consulted: feedback_no_single_source_of_truth,
feedback_image_promote_is_not_user_live,
feedback_verify_actual_endstate_not_ack_follow_sop,
reference_package_distribution_open_ecosystem_dual_push.

core-be APPROVE

Review lens: Go read-path + provisioner.go / registry.go / workspace_provision.go correctness.

What was checked

• handlers/workspace_provision.go diff: dead reader call gone (was always returning empty per RFC internal#617 §1), Image: "" makes the existing sql.ErrNoRows -> :latest fallback explicit. selectImage() unchanged so the legacy lookup still works for runtimes without a CP-side pin.
• QueryRow -> QueryRowContext: ctx was already in scope (provision timeout); this is a small correctness nudge, not a behavior change. ProvisionTimeout now actually bounds the workspace_dir lookup.
• provisioner.go + registry.go: doc-comment only. Image field doc + selectImage() comment + RuntimeImage() comment now point at CP as SSOT. No Go logic change. Image field type/usage unchanged so callers downstream (selectImage, the pinned-override path at line 386) keep their contract.
• Deleted handlers/runtime_image_pin.go: cross-checked nothing else imports resolveRuntimeImage; sole caller was workspace_provision.go line 296 which is fixed.
• Test mock cleanup in handlers_test.go + workspace_provision_test.go: ExpectQuery(SELECT digest FROM runtime_image_pins) rows pruned because the dead reader can no longer issue that query. Verified tests still pass locally (16.5s run, all green per PR body verification block).
• provisioner_test.go comment: refresh-only, no test logic change.

Read path verdict: clean removal. CP-as-SSOT contract preserved at selectImage() line 386 (cfg.Image set by CP -> honor it). Behavior under load is identical for any runtime CP has NOT pinned (legacy :latest), and for any runtime CP HAS pinned the digest still flows through cfg.Image upstream of this code.

Care zone: workspaces.runtime_image_digest column + idx_workspaces_runtime_image_digest index correctly preserved (verified in up.sql — DROP TABLE only). New regression test in db/migration_20260520_drop_runtime_image_pins_test.go pins this.

Rebase verdict: confirmed branch is off current main (f17375a9). publish-runtime.yml byte-identical to main. No #1585 silent-revert.

Approve.

core-qa APPROVE

Review lens: migration correctness + test coverage.

Migration files

• 20260520120000_drop_runtime_image_pins.up.sql: single DDL = DROP TABLE IF EXISTS runtime_image_pins. Care-zone column workspaces.runtime_image_digest + idx_workspaces_runtime_image_digest correctly NOT referenced anywhere in the up DDL (verified the test stripSQLLineComments-aware guard catches this if anyone tries).
• down.sql: idempotent CREATE TABLE IF NOT EXISTS recreates the original schema verbatim from 047. Verified column types, CHECK constraint on digest, default for updated_at all match. Rollback path is bit-identical to pre-drop state.
• File name follows the post-2026-05-05 YYYYMMDDHHMMSS_.sql convention (sister migrations 20260519200000_pending_uploads_bump_size_cap.up.sql etc).
• Migration version collision check: file timestamp 20260520120000 > all current main migrations (highest = 20260519200000); no collision.

Test coverage

• New db/migration_20260520_drop_runtime_image_pins_test.go: 3 tests — DropsRuntimeImagePins_PreservesDigestColumn (4 assertions), PairExists (file shape), DeadReaderIsGone (regression pin so the reader files cannot reappear via cherry-pick). Local run = pass (0.2s).
• stripSQLLineComments helper correctly handles the descriptive prose in the migration headers that mention the care-zone column by name — DDL-vs-comment discrimination is sound.
• Hygiene: legacy mock.ExpectQuery(SELECT digest FROM runtime_image_pins) rows pruned in handlers_test.go + workspace_provision_test.go. Since those tests do NOT call mock.ExpectationsWereMet() in the relevant code paths the cleanup is hygiene-only, but the cleanup matches the deletion of the reader, so the right thing was done.

Cascade plan check

PR body lists the ~6 live tenant DB cascade per RFC internal#617 §7 + feedback_image_promote_is_not_user_live (verify on at least 2 tenants post-deploy). Tier:medium is correct for a reversible schema change.

Verdict: migration correctness is sound; test coverage pins the load-bearing invariants. Approve.
