fix: resolve SourceResolver naming conflict, SSRF guard placement, and multiple test regressions

- plugins/drift_sweeper.go: rename SourceResolver→PluginResolver to avoid redeclaring the interface already defined in source.go (core#228) - handlers/workspace.go: move SSRF guard before BeginTx so URL rejection never touches the DB (core#212 fix — same pattern as registry.go:324) - handlers/restart_signals.go: convert rewriteForDocker standalone function to a method on *WorkspaceHandler; fix two call sites to use h.rewriteForDocker - handlers/plugins.go: change Sources() return type from plugins.SourceResolver to pluginSources (the narrow interface satisfied by *Registry) - handlers/admin_plugin_drift.go: remove unused "context" import - handlers/delegation_test.go: remove stray closing brace - handlers/restart_signals_test.go: rewrite with correct miniredis v2 API (mr.Get takes context, mr.Set requires TTL), resolveURLTestWrapper embedding pattern, and corrected Redis key handling - handlers/workspace_test.go: use http://localhost:8000 for SSRF-safe test (no DNS required); remove spurious mock.ExpectExec for Redis CacheURL call Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

 # sop-tier-check — verify a Gitea PR satisfies the §SOP-6 approval gate.
 #
-# Reads the PR's tier label, walks approving reviewers, and checks each
-# approver's Gitea team membership against the tier's eligible-team set.
-# Marks pass only when at least one non-author approver is in an eligible
-# team.
+# Reads the PR's tier label, walks approving reviewers, and checks team
+# membership against the tier's approval expression. Passes only when
+# ALL clauses in the expression are satisfied by the set of approving
+# reviewers (AND-composition; internal#189).
+#
+# Expression syntax:
+#   "team-a"          — OR-set: any ONE of the comma-separated teams
+#   "team-a AND team-b" — AND: BOTH must each have ≥1 approver
+#   "(a,b,c)"         — OR-set wrapped in parens; same as "a,b,c"
+#
+# Example: "qa AND security AND (managers,ceo)" means:
+#   ≥1 approver in team "qa"  AND
+#   ≥1 approver in team "security"  AND
+#   ≥1 approver in team "managers" OR "ceo"
+#
+# Per the spec (internal#189), the hard gate here pairs with the
+# advisory gate of sop-conformance LLM-judge (internal#188): each
+# required-team click must reflect real verification (visible in review
+# body or A2A messages), not rubber-stamp APPROVE. Both gates together
+# close the "teammate clicks APPROVE without verifying" gap.

+#   - Dropped `environment:` declarations — Gitea Actions does not support
+#     named environments (used by GitHub OIDC token gates)
+#   - Replaced `github.ref_name` (GitHub-only) with `${GITHUB_REF#refs/heads/}`
+#     — Gitea Actions exposes GITHUB_REF in the same format as GitHub Actions
+#   - docker/setup-buildx-action and aws-actions/configure-aws-credentials are
+#     GitHub Marketplace actions; they are installed by Gitea Actions runners and
+#     work identically here
+#   - All other variables (GITHUB_SHA, GITHUB_REPOSITORY, GITHUB_OUTPUT,
+#     secrets.*) use the same syntax as GitHub Actions

+# Registry note (2026-05-10): This workflow previously used GHCR
+# (ghcr.io/molecule-ai/platform-tenant) — that registry was retired
+# during the 2026-05-06 Gitea suspension migration when publish-
+# workspace-server-image.yml switched to the operator's ECR org
+# (153263036946.dkr.ecr.us-east-2.amazonaws.com/molecule-ai/
+# platform-tenant). The GHCR → ECR migration was never applied to
+# this file, so canary-verify was silently smoke-testing the stale
+# GHCR image while the actual staging/prod tenants ran the ECR image.
+# Result: smoke tests could not catch a broken ECR build. Fix:
+#   - Wait step: reads SHA from running canary /health (tenant-
+#     agnostic, works regardless of registry).
+#   - Promote step: calls CP redeploy-fleet endpoint with target_tag=
+#     staging-<sha>, same mechanism as redeploy-tenants-on-main.yml.
+#     No longer attempts GHCR crane ops.

+# Admin Authentication Runbook
+
+## Test-token route: lock in staging and production
+
+The `GET /admin/workspaces/:id/test-token` endpoint mints fresh workspace auth tokens.
+It is gated by `TestTokensEnabled()` which returns `true` only when `MOLECULE_ENV != "production"`.
+
+**Effect**: if `MOLECULE_ENV` is unset or set to `development` / `dev` in a staging or production
+tenant, the test-token route remains enabled. While the route is protected by `subtle.ConstantTimeCompare`
+against `ADMIN_TOKEN` (returns 404 when disabled, not 403), the safest posture is to lock it
+out in any environment where it is not intentionally used.
+
+### Required: set MOLECULE_ENV in all non-dev environments
+
+```bash
+# In your tenant / EC2 / Railway environment variables:
+MOLECULE_ENV=production
+```
+
+This matches the production tenant default. When `MOLECULE_ENV=production`:
+
+- `TestTokensEnabled()` → `false`
+- `GET /admin/workspaces/:id/test-token` → 404 (route disabled)
+
+### Startup visibility
+
+workspace-server logs the test-token route state at boot:
+
+```
+Platform starting on ... (dev-mode-fail-open=...)
+```
+
+Additionally, when `TestTokensEnabled()` is `true` (route enabled), the server emits an INFO line
+so operators can confirm the setting in logs:
+
+```
+[molecule-git-token-helper] NOTE: /admin/workspaces/:id/test-token is ENABLED
+(running with MOLECULE_ENV != production)
+```
+
+If you do not see this line and the route is still accessible, verify `MOLECULE_ENV` is not set to
+`development`, `dev`, or any value that is not exactly `production`.
+
+### Dev environments
+
+In local dev (`MOLECULE_ENV=development` or unset with no `ADMIN_TOKEN`), the test-token route
+is intentionally enabled — it is the only way to bootstrap a workspace bearer token without a running
+canvas. This is the correct default for developer workstations.
+
+## Admin bearer token (`ADMIN_TOKEN`)
+
+The platform uses `ADMIN_TOKEN` as the bearer credential for admin-gated endpoints:
+
+| Endpoint | Auth method |
+|----------|-------------|
+| `GET/POST/PATCH/DELETE /workspaces` | `Authorization: Bearer <ADMIN_TOKEN>` |
+| `GET /admin/liveness` | `Authorization: Bearer <ADMIN_TOKEN>` |
+| `POST /org/import` | `Authorization: Bearer <ADMIN_TOKEN>` |
+| `GET /admin/workspaces/:id/test-token` | `Authorization: Bearer <ADMIN_TOKEN>` (enabled only when `MOLECULE_ENV != "production"`) |
+
+Missing or invalid `ADMIN_TOKEN` → AdminAuth fails open in dev mode (no token set), or
+returns 401 in production mode (token set but invalid).
