Closes #1735.
Phase 1 — Investigation
Awareness namespaces were a memory-routing surface (
AWARENESS_URL+AWARENESS_NAMESPACEenv vars on the workspace container) that was plumbed across the platform but never wired in any environment:controlplaneprod env (59227671-8459-4d68-8f64-2fb868d3c0d8)AWARENESS_*keys (0 / 70 vars).controlplanestaging env (639539ec-f84b-44c9-b90f-2a57dccb736c)AWARENESS_*keys (0 / 69 vars)./etc/molecule-bootstrap/{all-credentials.env,secrets.env,agent-secrets.env},/opt/iam/)internal/provisioner/provisioner.go:709(pre-change)Verified 2026-05-23 via the Railway GraphQL API.
The column
workspaces.awareness_namespace(migration 010) was populated for every row, but only ever held the canonicalworkspace:<id>string — the same value the v2 namespace resolver derives on its own atinternal/memory/namespace/resolver.go:186. Removing the column changes no agent-visible namespace.Phase 2 — Design
Single PR. Backend-only — the canvas
<iframe>block inMemoryTab.tsxis handled separately in PR #1749 (which closes #1734) by deleting the dead component entirely. No canvas surface change in this PR.Migration shape mirrors

Stage A — Local platform boot / build / tests

Stage C — Real-task runtime smoke
Docs follow-up
The broader docs sweep (~30 "awareness namespace" mentions across architecture docs, runtime config docs, READMEs, superpowers plans, and one postmortem) is tracked in #1753 as a docs-only follow-up. The two API-spec lines (
docs/api-reference.mdrow 106 for theworkspacestable description, anddocs/api-protocol/platform-api.mdline 93 claiming workspace creation assigns an awareness namespace) are patched in this PR because they describe an API contract and would mislead external integrators post-merge.Risks
ProvisioningPayload.AwarenessNamespacewas removed; a quick grep of~/molecule-core/shows no other repo in the workspace consumes it, but a reviewer with broader visibility (CP, molecule-sdk-python) should confirm before merge.workspaces.awareness_namespacevalue is the derivableworkspace:<id>string — no information is lost by dropping the column.Sequencing

Scheduled post-merge. The deletion is dark on every existing tenant (
AWARENESS_*env vars confirmed unset on Railway controlplane prod + staging via GraphQL audit 2026-05-23). Stage B is a workspace-create + workspace-restart smoke against staging after merge to confirm no INSERT references the dropped column path.4. Root-cause not symptom
Root cause: an entire memory-routing surface (env-var-controlled awareness namespaces) was plumbed across the model layer, provisioner, handlers, tests, and docs but never wired in any environment. The symptom — "extra config to maintain, dead code in code review, stale docs" — is downstream of the root cause "the feature was never used." This PR removes the cause rather than working around the symptoms.
5. Five-Axis review walked
Yes. Hostile Five-Axis review dispatched (see PR comments). External
agent-reviewerposted REQUEST_CHANGES againstfe59d8dflagging stale docs in.env.exampleand the API spec files — all three addressed in subsequent commits (013c8cfeAPI docs,d7f61f97.env.example).6. No backwards-compat shim / dead code added
Net deletion: +113/−163 LOC. Down migration restores the dropped column as a no-op safety net for revert. No shim, no compat layer — the feature was never live so there's no live caller to compatibilize.
7. Memory/saved-feedback consulted
feedback_no_single_source_of_truth— drives the removal: an inactive secondary backend is itself drift.reference_merge_gate_model_changed_2026_05_18— drives the 2-non-author approval expectation post-rebase (force-pushes dismissed prior approvals).feedback_per_agent_gitea_identity_default— approving agents must post under their own Gitea persona, not the founder PAT.5-axis review on
fe59d8d:Correctness: REQUEST_CHANGES. The backend/schema cleanup removes
WorkspaceConfig.AwarenessURL,WorkspaceConfig.AwarenessNamespace, container env injection, theworkspaces.awareness_namespacecolumn, and the create-handlerawareness_namespaceresponse. However the repo still documents and exposes the removed surface in tracked files:.env.examplestill saysAWARENESS_URLis injected with a deterministicAWARENESS_NAMESPACE;docs/api-protocol/platform-api.mdsays workspace creation assignsawareness_namespaceand later injects it into the runtime;docs/api-reference.mdstill listsworkspaces.awareness_namespace; and runtime docs still describeAWARENESS_URL/AWARENESS_NAMESPACErouting. After this PR those instructions are false and will lead operators/SDK consumers to configure env vars or expect response/schema fields that no longer do anything. Please update or explicitly mark these docs as legacy/deferred in this PR, at least for.env.exampleand the API/protocol docs that describe the removed backend contract.Robustness: The migration shape and idempotent
DROP/ADD COLUMN IF EXISTSare reasonable; memory seeding still computesworkspace:<id>.Security: No new secret/auth surface found; removing dead env injection reduces stale config exposure.
Performance: No meaningful runtime performance risk.
Readability: The code rename to
workspaceMemoryNamespaceimproves intent, but leaving stale documentation makes the final contract unclear.fe59d8d097to013c8cfe58Post-rebase Stage A re-confirmation (#1737 review-finding process gap):
