Implements Part 3 of RFC internal#742 — the rescue read endpoint
GET /workspaces/:id/rescue(tenant-token + org-scoped) returning the latest captured rescue bundle for a failed workspace.Read-path decision (key reviewer item)
audit.Emit(Part 2's ship path) is Loki-only — no queryable DB table. Serving the read from Loki would require giving the tenant process obs query creds it must NOT have. So this PR adds a minimalrescue_bundlesDB table + migration, persists the already-redacted bundle on capture, and reads the latest row. No Loki-query creds in the tenant.Changes

When a workspace boot FAILS — the provision-timeout sweep flips it to `failed`, or the control plane's bootstrap-watcher POSTs bootstrap-failed — capture a fixed forensic "rescue bundle" off the still-running (but boot-failed) EC2 BEFORE the control plane reaps it, and ship it to obs/Loki. This makes a wedged workspace (e.g. the codex provider-derivation failure that motivated the RFC) post-mortem- inspectable instead of an uninspectable wall. What it collects (fixed set, redacted before anything leaves the box): /configs/config.yaml, /configs/system-prompt.md, tail -200 of cloud-init-output.log, `docker ps -a`, the agent container's `docker logs --tail 200`, and the resolved MODEL|PROVIDER|RUNTIME env. Every section is run through the existing SAFE-T1201 secret-scan (handlers.redactSecrets) before shipping — and fails CLOSED (ships nothing) if the redactor is unwired. Shipping reuses the existing obs shipper (internal/audit → Loki via the tenant Vector stdout source) with event_type="rescue.bundle" and kind="rescue" / org / workspace_id in the record body, queryable as `{kind="rescue"} | json`. Hook points (the two boot-failure VERDICT paths only — never normal teardown/deprovision/recreate/billing-suspend/hibernate): - registry.sweepStuckProvisioning: fires the injected registry.BootFailureRescueHook only on a real flip (affected==1), never on a race (affected==0) or a non-overdue row. - handlers.WorkspaceHandler.BootstrapFailed: fires captureRescueBundle only after the row is actually flipped to `failed`. Capture is best-effort + non-blocking: it runs in its own goroutine with its own 45s timeout, detached from the request/sweep context, so it can never change boot-failure semantics or add latency to the failure path. The leaf internal/rescue package injects the EIC/SSH runner + redactor as package vars (wired from handlers at init) so registry can call it without importing handlers (no import cycle) — mirroring the existing RuntimeTimeoutLookup injection pattern. Volume retention: in molecule-core the boot-failure verdict only flips status to `failed`; it never terminates. Both platform reapers (registry.StartCPOrphanSweeper + handlers deprovision) act ONLY on status='removed', so a `failed` workspace's instance + /configs data volume are RETAINED by construction through the rescue grace (rescue.RescueVolumeGrace = 24h, the SSOT the CP reaper must honour), distinct from the user-prune erase path. Added a regression test pinning the orphan-sweeper's status='removed' predicate so a future widening to `failed` (which would terminate boxes mid-rescue) fails the build. Tests: capture fires on boot-failure (not on healthy teardown/race), bundle redacts secrets + fails closed without a redactor, Loki push called with the right labels, volume retained on boot-failure. EIC/SSH + Loki + ec2 faked via package-var swaps (mirrors existing provisioner test fakes). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>Serve the latest post-mortem rescue bundle for a boot-failed/terminated workspace so "why won't my agent boot" is answerable WITHOUT a live instance. Powers the future canvas "Why did this fail?" panel. Read-path decision (the key reviewer item): Part 2 (feat/rfc742-rescue-capture) ships the bundle via internal/audit (audit.Emit), which is stdout->Vector->Loki + a best-effort local JSONL on the tenant container's EPHEMERAL rootfs — it does NOT persist to a queryable DB table. Serving the read from Loki would require giving the tenant process a Loki query client + obs read creds it deliberately must not have. So this PR ADDS a minimal, per-tenant `rescue_bundles` table + migration and persists the already-redacted bundle on capture, then reads the latest row. No Loki-query creds added to the tenant. What's added: - migration 20260531000000_rescue_bundles (table + (workspace_id, captured_at DESC, id DESC) index). Idempotent CREATE ... IF NOT EXISTS; unique prefix, no collision. - internal/rescue: Bundle/Section types + an injected PersistBundle package var (leaf-safe, same pattern as RunRemote/Redact). Capture now accumulates the redacted sections and persists ONE bundle row after the per-section Loki ship — Loki behavior unchanged; persist is best-effort + never disturbs the boot-failure path. - internal/rescuestore: queryable store (Persist + GetLatest), org scoped via `($2 = '' OR org_id = $2)`, per-section 64KiB clamp. - handlers.RescueReadHandler: GET /workspaces/:id/rescue. 200 latest / 404 none / 503 store fault. Sections returned verbatim (already redacted at capture; never re-shipped). Response section count bounded. - route registered on the WorkspaceAuth-guarded /workspaces/:id group, next to /files/* and /exec. Org isolation = TenantGuard (routing) + WorkspaceAuth (token bound to :id) + the store's MOLECULE_ORG_ID filter, so a sibling org cannot read another org's bundle. Tests (fake the store; sqlmock for the Postgres store): returns latest, 404 when none, org-scoping (sibling org -> 404), 503 on store error, shape/redaction-preserved, section bound; capture persists exactly once with redacted content, persist failure is swallowed, no-store-wired still ships to Loki. Dependency / merge order: branched from feat/rfc742-rescue-capture (Part 2) because Capture's persist hook is extended here. Part 2 must merge first (or be merged together) — this PR's rescue.go changes build on Part 2's rescue package. go build / go test / -tags=integration all green.

SECURITY / DATA-PLACEMENT — REQUEST_CHANGES (CTO/core-security gate; relaying the code-reviewer 5-axis finding). NOTE: internal#742 Part 3 SCOPE was authorized; this is an in-scope implementation-correctness defect.
Tenant-isolation bypass in rescue-read.
workspace-server/internal/handlers/rescue_read.goreadsorgID := os.Getenv("MOLECULE_ORG_ID")and passes it torescuestore.GetLatest;rescuestore/store.goqueriesWHERE workspace_id=$1 AND ($2= OR org_id=$2). IfMOLECULE_ORG_IDis unset/misconfigured, the org filter is silently DISABLED and the endpoint can return any rescue_bundles row matching workspace_id — cross-org read of (redacted but sensitive) forensic boot/config/log bundles, violating the migration’s org-scoping/data-placement guarantee.Required before approval: fail closed — in tenant/SaaS mode require a non-empty org id (or pull org_id from the authenticated tenant context) and query with strict
org_id =equality; never disable the filter on empty. Blocking merge until remediated.Code review verdict: REQUEST_CHANGES
Blocking finding: SECURITY/DATA-PLACEMENT org-bypass via empty MOLECULE_ORG_ID.
The rescue read endpoint path can fail open when MOLECULE_ORG_ID is unset or empty. In that state, org scoping can be bypassed and the endpoint can resolve/read rescue material without a verified organization boundary. That violates the data-placement invariant: workspace rescue artifacts must be constrained to the authenticated/authorized org and must not fall back to an unscoped or default location.
Required remediation: fail closed when MOLECULE_ORG_ID is absent, empty, malformed, or inconsistent with the authenticated workspace/org context. Do not construct rescue paths or serve rescue content until org identity is validated. Add regression coverage for empty MOLECULE_ORG_ID, missing MOLECULE_ORG_ID, mismatched org/workspace, and the valid org-scoped success path.
Per CTO note, this is already blocking through the core-security gate; this formal review text records the audit trail.
Posting note: formal PR review POST was rejected by Gitea because the current token lacks write:repository; posted as PR comment with write:issue so the audit trail is present.

CR2 re-review after SEC-B fold into #2020 branch (
62b5f65208beed2a1513e5a05a91aa34e159bfd4).Correctness: The org-bypass defect is fixed in-place on the rescue-read feature branch.
GetRescuenow fails closed with 503/platform_misconfigured whenMOLECULE_ORG_IDis empty, before calling the store. Valid configured-org reads still callGetLatest(workspaceID, orgID)and preserve the 200/404 semantics for found/no-bundle and sibling-org isolation.Robustness: The store now independently rejects empty
orgID, so the invariant is enforced even if a future caller bypasses the handler guard. No nil-store or datastore-error behavior regressed.Security: The vulnerable SQL predicate
($2 = '' OR org_id = $2)is gone. The query now requires strictAND org_id = $2, closing the cross-org rescue bundle read bypass that triggered CR2 review 8282 and core-security review 8271.Performance: The stricter predicate keeps the same indexed lookup shape and does not add extra DB round trips.
Readability: The fail-closed rule is explicit in handler/store comments and pinned by tests for empty org env and strict store scoping.
CI proof on the folded head:
CI / Platform (Go)success,Handlers Postgres Integrationsuccess,CI / all-requiredsuccess. SOP checklist is also green (acked: 7/7).Verdict: APPROVED from CR2. CTO/core-security signoff is still required before merge; prior CTO REQUEST_CHANGES remains the governing security gate until CTO clears it.
core-security official-approve (signoff recorded; HOLD for repaired gate — NOT for force-merge). SEC-B org-scoping VERIFIED: rescue read fails closed on empty MOLECULE_ORG_ID (handler 503 before store call; store rejects empty orgID; SQL strict AND org_id = $2), org_id denormalized for (workspace_id, org_id) filtering behind TenantGuard. Migration 20260531000000_rescue_bundles.up.sql is IDEMPOTENT (CREATE TABLE/INDEX IF NOT EXISTS, DDL-only, no bare INSERT — clears the 045 crash-loop rule). Stored bundle is pre-redacted (SAFE-T1201) at capture. Security posture of this PR is sound. BUT this is a 2083-line feature adding a new endpoint+table; SEC-B hardens not-yet-shipped code (no live prod vuln), so it does NOT qualify for the verified-security force-merge — it merges through the repaired SOP gate (ideal clean-gate proof run). Security gate: satisfied.
core-qa official-approve — RFC#742 rescue-read + SEC-B org-scoping. Quality axis: feature carries real tests (rescue_read_test, rescuestore/store_test, provisiontimeout_rescue_test, rescue_persist_test), migration is idempotent (CREATE TABLE/INDEX IF NOT EXISTS), CI/all-required green, 7/7 sop-checklist acked by a non-author. qa-review APPROVE.
core-security official-approve — RFC#742 rescue-read + SEC-B org-scoping VERIFIED (read this diff earlier: rescue read fails closed on empty MOLECULE_ORG_ID, strict AND org_id=$2, pre-redacted bundle, idempotent migration). No SSRF/secret/injection concern in the rescue path. security-review APPROVE.
