Finding

Protected Foundation owns PostgreSQL acceptance in one canonical Foundation CI / Repository quality job. #310/#311 replace the historical filename switchboard with owner-neutral discovery and fail-closed execution provenance while remaining stacked on #259.

The runtime lane binds root/companion bytes and transitive repository inputs to an immutable exact-candidate tree, executes as a dedicated non-owner with scrubbed environment, denies live-workspace traversal, requires process quiescence, fixes executable-search authority to a reviewed literal PATH, and creates the private XDG runtime directory before execution.

A fresh exact-head CodeRabbit audit of a97afd2... then found a separate provenance-preflight defect: tests/test_foundation_postgres_contracts.py had legitimately advanced to exact-tree assertions, but the workflow still expected its predecessor SHA-256. The sealed workflow would therefore fail before the inventory regression could run.

Current exact authority

  • base: ci: enforce declared Python package compatibility #259 fix/foundation-declared-python-compatibility@f1f152b0838e11cba1cf583706eb0983d56af373
  • exact head: dbc2fcf70ba6a6883381e8526cd62c6e19ce159c
  • state: open · Draft · mechanically mergeable
  • scope: Foundation PostgreSQL discovery/execution acceptance only; no HR domain truth, migration semantics, runtime service logic, provider/model, or consumer contract change

Latest RED → causal repair

  1. 3c15d40da6a870a4620016c548e11885a6c2b2a9 — executable regression requires a literal reviewed executable-search PATH, rejects PATH="$PATH", and requires the XDG runtime directory to be created by the dedicated contract principal with mode 0700.
  2. 2dc8b4d703399b69fab844d1f0dfe073217ed392 — creates $contract_runtime/.runtime via /usr/bin/install -d -m 0700 as orgmetra_pg_contract, and pins contract PATH to /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin under env -i.
  3. a97afd2354a181c3dad03557001aa1379c318a42 — resealed the runtime repair, then exact-head review correctly found its stale child-test digest.
  4. 31c95f3d9d99edd4cc8bc748c4b2888b064b322a — causal provenance repair. ORGMETRA_POSTGRES_TEST_SHA256 is updated to the exact current tests/test_foundation_postgres_contracts.py SHA-256 7b96082acb24f5a49cb6015be620b7ef675a6fda7943eb1c73816db8d832c3d3; the regression itself is not reverted or weakened.
  5. dbc2fcf70ba6a6883381e8526cd62c6e19ce159c — reseals manifest.json to the resulting final workflow bytes.

The current workflow keeps immutable exact-candidate-tree execution, reviewed root/companion digest binding, literal executable-search authority, env -i, disposable HOME/TMPDIR/XDG state, live-checkout traversal denial, and process-quiescence controls. The previously verified local/static runtime tests remain relevant to the unchanged runtime code; the provenance repair itself is a same-length one-digest correction and is verified against the exact current child-test digest. This is still not protected-base runtime admission.

Evidence boundary

Hosted GREEN is not claimed. This PR correctly targets #259 rather than develop; exact head dbc2fcf... therefore has no protected-base PR-triggered Foundation run under pull_request.branches: [develop]. Devin Review/CodeRabbit commit statuses are review signals only, not PostgreSQL runtime acceptance or a qualifying independent approval, and predecessor results are not transferred across head movement.

Integration boundary

Keep Draft until #259 normally integrates or this stack is ordinary-forward reconciled onto then-current protected Foundation truth. Then reacquire exact-head Foundation/SAST/Security/CodeQL/OpenCode/Noema/Strix plus qualifying independent approval before normal merge. Do not self-approve, routinely bypass, synthesize statuses, create a no-op retrigger, restore feature-local quality workflows, weaken gates, force-push, or destructively rebase.

Merge Risk: 🟡 Moderate · up to 15ec7

Registered root or companion paths can resolve to duplicate underlying scripts, so CI may accept and execute an inventory that does not represent distinct reviewed files. This should be fixed before merge.

Current-head source audit on 15ec7bf142503f0e92a0feb8b13f164cfeb32613 found one integrity gap that should be repaired in this stack before it is treated as the #310 successor.

.github/scripts/foundation-postgres-contracts.py accepts any matching path for which Path.is_file() is true, and _sha256() follows the path. On Linux that admits a symlink such as tests/test_new_owner_postgres.sh -> test_existing_postgres.sh: discovery sees a distinct owner root, the registry can bind the target bytes, and Foundation then executes the same underlying contract through a second name. A companion path can use the same indirection. That makes the declared/executed set look complete while the new owner contract has no independent bytes, which conflicts with #310's integrity-bound/non-vacuous acceptance.

Repair should be test-first and fail closed on filesystem indirection rather than merely hashing the resolved target. Minimum regression: a discoverable PostgreSQL root symlink to an existing valid root must be rejected; a companion symlink must also be rejected. The path validator should require a repository-contained regular file with no symlink at the bound path (and preferably verify the resolved path remains under the repository root). Keep the current registry/digest model, single Foundation job, dynamic DATABASE_URL, and generic companion composition unchanged. After changing the validator/tests, reseal the inline provenance hashes and manifest.json from final bytes; predecessor/local 16/16 evidence must not be carried forward to the new head.

Fresh exact-head audit of 2f5a8ed93718acb4b057eae7849a6c69e0cc2807 found a remaining checked-versus-used integrity gap in the PostgreSQL execution lane.

The initial provenance step validates the registry/validator/tests and the execution step obtains a validated root list, but each reviewed root is later executed from the mutable checkout path. More importantly, after that root has executed, the workflow calls foundation-postgres-contracts.py companions "$contract" again. That second call re-reads the live registry and re-hashes live workspace files. A root contract can therefore mutate a later root, its own companion, or the registry between initial validation and later use. The final executed[*] == contracts[*] comparison proves path cardinality/order only; it does not prove the bytes actually executed are the bytes in the pre-execution reviewed inventory. A final git diff is too late to be execution authority, and a mutation restored before read-only validation can erase the residue while unreviewed bytes have already run.

This is a repair finding, not a Close condition. Keep the current symlink hardening and single-job/dynamic-DATABASE_URL design, but make the execution plan one-shot and checked-versus-used:

  1. Before any PostgreSQL contract executes, materialize one validated evidence snapshot containing every active root/companion path and exact SHA-256; load that snapshot into parent-shell memory, then remove any temporary plan files.
  2. Do not re-read registry/companion authority after the first contract starts. In particular, remove the post-root live companions "$contract" lookup.
  3. Immediately before every root and companion bash execution, recompute its SHA-256 and require equality with the pre-execution snapshot. After the full set, recheck all bound scripts so self/previous-script mutation also fails closed.
  4. Add a RED regression that would fail the current workflow if one contract changes a later root/companion (or registry binding) between initial inventory validation and execution. The repaired contract must fail before altered bytes execute, not merely at final clean-checkout validation.
  5. Reseal the inline validator/test provenance and manifest.json from the final workflow bytes. Predecessor local/hosted evidence does not transfer.

Do not solve this with a second workflow, sleeps/polling, a fixed filename switchboard, or by treating repository cleanliness after execution as equivalent to pre-use byte identity.

@seonghobae I reviewed exact head 758c7a2da720155669f43bd2b79221070e247c67.

I found one remaining checked-versus-used integrity gap.

High — The digest check and bash execution still have a TOCTOU gap.
At .github/workflows/foundation-ci.yml Line 184, verify_contract_bytes "$contract" hashes the pathname. At Line 185, bash "$contract" opens that pathname again. A previously executed contract can start a background process that modifies a later root after Line 184 completes but before Bash opens it. The same condition exists for companions at Lines 189-191. In that case, unreviewed bytes can execute even though the pre-use check succeeded.

The execution lane must execute immutable verified bytes. For example, materialize each validated bound script into a private execution snapshot before any contract starts, verify that snapshot against the evidence digest, and execute only the snapshot copy. Preserve the root-to-companion mapping in parent-shell memory. Do not execute the mutable checkout pathname after verification.

tests/test_foundation_postgres_contracts.py Line 250 is also not the required RED regression. It checks workflow text only. Add a behavioral regression that makes an earlier contract modify a later root or companion during the check-to-execution interval. The test must prove that the altered script does not execute.

The one-shot evidence plan, removal of live companion lookups, inline provenance hashes, and manifest.json values are correct for this exact head.

Please review current exact head 818ab0539310f4ca4e6ebeb76323f42ea05640c7. The delta after the previous reviewed head is limited to the runtime path-identity regression, the pre-use ancestor-symlink/containment repair, and the manifest reseal; predecessor review evidence should not be transferred.

@seonghobae I reviewed exact head 818ab0539310f4ca4e6ebeb76323f42ea05640c7.

High — The workflow still executes a mutable pathname after validation.
In .github/workflows/foundation-ci.yml, Line 213 verifies $contract, but Line 214 then runs bash "$contract". For a companion, Line 218 verifies $companion, but Line 220 then runs bash "$companion". verify_contract_path_identity() detects symlinks that exist during verification, but it does not make the later bash open use the verified file.

An earlier contract can start a background process that replaces a later root or companion after its digest and path-identity checks return. Bash can then execute altered bytes. The new test at tests/test_foundation_postgres_contracts.py Line 250 only checks workflow text. It does not provide the required behavioral regression for this interval.

Materialize the validated scripts into a private execution snapshot before any PostgreSQL contract starts. Verify each snapshot file against the one-shot evidence digest. Execute only snapshot files. Add a behavioral regression where an earlier contract changes a later root or companion, and verify that the altered payload does not execute.

The resealed inline provenance values and the manifest.json entry match the exact current-head bytes.

@seonghobae I reviewed exact head dbc2fcf70ba6a6883381e8526cd62c6e19ce159c.

I found no remaining current-head provenance or false-GREEN issue in the reviewed PostgreSQL Foundation scope.

The provenance preflight now binds tests/test_foundation_postgres_contracts.py to SHA-256:

7b96082acb24f5a49cb6015be620b7ef675a6fda7943eb1c73816db8d832c3d3

All four inline PostgreSQL provenance hashes match their exact-head files.

manifest.json matches .github/workflows/foundation-ci.yml:

  • SHA-256: 025a9a0588f68720640bf46a754f62444ff44c8ef48b69a79fd4fbd391083be2
  • Bytes: 24,325
  • Lines: 528

The preflight runs the digest checks before it runs the PostgreSQL regression tests or contracts. The exact-tree execution assertions remain present. The workflow has no stale 9c90ed... digest.

This review does not establish hosted Foundation admission evidence. No predecessor review or hosted result was transferred.

Please review exact current head dbc2fcf70ba6a6883381e8526cd62c6e19ce159c. The prior stale child-test digest has been ordinary-forward repaired (31c95f3...) and the resulting workflow resealed (dbc2fcf...). Verify the corrected exact-tree regression remains intact, the workflow now binds SHA-256 7b96082acb24f5a49cb6015be620b7ef675a6fda7943eb1c73816db8d832c3d3, and the manifest binds the resulting workflow SHA-256 025a9a0588f68720640bf46a754f62444ff44c8ef48b69a79fd4fbd391083be2 / 24,325 bytes / 528 lines. Treat any evidence/provenance drift as blocking.

@seonghobae I reviewed exact head dbc2fcf70ba6a6883381e8526cd62c6e19ce159c.

I found no current-head evidence or provenance drift in the requested PostgreSQL Foundation scope.

The provenance preflight binds tests/test_foundation_postgres_contracts.py to:

7b96082acb24f5a49cb6015be620b7ef675a6fda7943eb1c73816db8d832c3d3

All four inline PostgreSQL provenance hashes match their exact-head files.

The corrected exact-tree regression remains intact. It requires execution through:

bash -c 'cd -- "$1" && exec bash "$2"'

It rejects direct execution through bash "$snapshot_script".

manifest.json matches .github/workflows/foundation-ci.yml:

  • SHA-256: 025a9a0588f68720640bf46a754f62444ff44c8ef48b69a79fd4fbd391083be2
  • Bytes: 24,325
  • Newlines and lines: 528

This review does not establish hosted Foundation admission evidence.

Owner handoff from #312 for future ordinary reconciliation; no #311 source mutation is requested while the stacks are separate.

#312 exact 4535d9fea7b2b995be627a23316a65474d714957 now carries the three existing document_records idempotency PostgreSQL roots plus one reviewed companion: tests/document_record_idempotency_postcommit_recovery_companion.sh, current SHA-256 a5b5f1d36ad1ccd6c04fab83e057dcace786e26ff0adb346cbbf7cefe45c14a9 (10,448 bytes / 251 lines).

When #107/#312 are ordinary-forward reconciled into the Foundation owner history, bind this script as a companion of tests/test_document_record_idempotency_postgres.sh; do not turn it into a fourth filename-specific root or add a workflow switch. The companion deliberately does not apply migrations. It fails closed unless the main root has already established document_record_persist_receipt and persist_document_record_once(...), then proves a post-commit connection termination can recover the exact durable first result without duplication or leaked named sessions.

Preserve #311's existing checked-byte/path/exact-tree/environment/process-quiescence guarantees when the companion is admitted, and reseal registry/workflow provenance only after the histories are actually reconciled.

#312 authority advanced to ebe5ec1c297eb48f95363aff5123163b09b10430 with a recovery-fixture checked-versus-used repair. When #312 is reconciled into the PostgreSQL Foundation stack, keep tests/document_record_idempotency_postcommit_recovery_companion.sh as the reviewed companion of the main document-record idempotency root (not a fourth filename-specific root), but preserve its current backend identity invariant: execution-unique UUID-derived PGAPPNAME, observation of durable receipt + PgSleep, capture of (pid, application_name, backend_start), and termination/EXIT cleanup only through an exact still-live identity match. PID-only pg_terminate_backend(<captured pid>) is not acceptable because PID reuse can turn a checked backend into a different used backend. The source regression tests/test_document_record_idempotency_postcommit_recovery_contract.py records that invariant; do not copy mutable #312 source into #311 before ordinary-forward reconciliation.

Superseding #312 handoff: exact authority is now 8dc8527a5e85920798f49609546892ff1c03eee1. CodeRabbit found one valid test-contract gap on ebe5ec1...: the new regression verified guarded backend termination predicates but did not itself prove EXIT cleanup() called the guarded helper. 8dc8527... closes that without changing the recovery fixture or migration semantics: the regression extracts cleanup(), requires terminate_captured_backend, forbids direct pg_terminate_backend there, requires backend_start_epoch, and preserves best-effort abort cleanup. Foundation reconciliation should consume this successor, not ebe5ec1....

Superseding #312 authority after exact-head review: eb99d8e93741215ba3940fc616ab8b875bc7b3bf. CodeRabbit found that predecessor 8dc8527... still searched the whole companion for asserted-termination predicates, so unused guarded text could preserve a false-GREEN even if terminate_captured_backend() regressed. The successor changes only the source regression: it extracts terminate_captured_backend() and requires, inside that function body, the captured PID/application-name/backend-start predicates, exactly one pg_terminate_backend(pid), no direct pg_terminate_backend(${backend_pid}), and exact 1|true; the existing cleanup-specific regression remains. Recovery-shell/migration behavior is unchanged. Foundation reconciliation should consume eb99d8e..., not predecessor test evidence.

Superseding #312 authority after third exact-head review: 58d6d680db6ef6f4b445e4c791d2d5d4377e882e. CodeRabbit correctly found eb99d8e... still allowed an alternate PID-only termination call with different whitespace/helper structure to coexist with the guarded call. The successor changes only the source regression: it regex-extracts every pg_terminate_backend invocation from the entire companion, requires exactly one global invocation with argument pid, requires that same sole invocation inside terminate_captured_backend(), and requires cleanup to contain zero termination invocation. Recovery shell and migration semantics remain unchanged. Foundation reconciliation should consume 58d6d68... test authority.

Superseding #312 authority after comment-aware review finding: 36a806765663c88c08184acfad3a35a9900afa93. CodeRabbit correctly showed the predecessor regex could miss a PostgreSQL termination call with block/line comments between lexical tokens. The successor chooses a stricter fail-closed source contract rather than parsing SQL embedded in shell: pg_terminate_backend must occur exactly once lexically in the complete companion, that sole occurrence must be inside terminate_captured_backend(), and it must be the reviewed literal pg_catalog.pg_terminate_backend(pid); cleanup contains zero occurrences. Runtime fixture/migration semantics remain unchanged.

#312 owner handoff update: document_records idempotent persistence has advanced to exact 874a3eb2f26af094a604c8fe9b07b8a946b54e8f. Review found a distinct database-capability gap: PostgreSQL grants EXECUTE on newly created functions to PUBLIC by default, so migration 0024 now revokes EXECUTE on persist_document_record_once(uuid,text,uuid,text,text,text,text,text,text,text,text,text,text,text,timestamptz,text,text,text,text,text) from PUBLIC inside the same transaction that creates it. New root tests/test_document_record_idempotency_function_acl_postgres.sh creates a run-unique NOLOGIN/NOBYPASSRLS role, requires EXECUTE=false for that role and true for the owner, and requires a SET ROLE invocation to fail at function authorization before command validation. After normal stack reconciliation, Foundation owner-neutral discovery must admit four document-record idempotency PostgreSQL roots plus the existing reviewed post-commit recovery companion. Do not add a filename-specific switch or copy mutable #312 source into #311.

Reconciliation handoff from #312 exact 8e86c42d5545b9025341dca9afc220666ab56c93: document-record idempotency now includes a fourth owner-neutral PostgreSQL root, tests/test_document_record_idempotency_function_acl_postgres.sh. Keep generic discovery; do not add a filename-specific workflow switch. After #107/#312 history is ordinary-forward reconciled into this Foundation stack, the registry must execute all four roots in separate isolated PostgreSQL containers and keep tests/document_record_idempotency_postcommit_recovery_companion.sh as the reviewed companion of the main idempotency root. The ACL root requires migration 0024's fresh NOLOGIN/NOBYPASSRLS capability roles, restricted SECURITY DEFINER owner, executor with function EXECUTE only and no direct document/receipt table DML, plus fail-closed reserved-role collision behavior. Existing exact-tree, env-scrub, non-owner process, quiescence, and transitive-input controls remain prerequisites.

People owner handoff from #314 / canonical #64: a new focused root contract now exists at tests/test_employment_separation_postgres.sh on fix/hire-identity-type-integrity (current People head includes it). It exercises migration 0014_employment_separation_transition.sql: correction-not-rewrite history, DB-owned audit time, same-key replay/semantic conflict, stale-version, cross-tenant, future Employment-version and Assignment fail-closed cases, plus exact-key concurrent first attempts with pg_blocking_pids(...) evidence for the advisory-lock blocker relationship.

Please let Foundation owner-neutral discovery register this contract after the #64 delta is normally reconciled into the Foundation stack. Do not add a filename-specific workflow branch or copy the migration/test into #311. The focused trace is docs/traceability/employment-separation.md; ADR 0015 remains Proposed until the registered PostgreSQL contract has exact-head hosted GREEN.

People-owner handoff from #314/#64: after the People separation slice reaches the normal Foundation stack, owner-neutral PostgreSQL discovery must admit both tests/test_employment_separation_postgres.sh and tests/test_employment_separation_capability_postgres.sh from the immutable exact-candidate tree. Do not add a filename-specific workflow switch or copy mutable #64 source into this stack.

The capability contract’s current owner head is #64 fdb33797fde1efc215ab0dcde474ce82e7d27dfd. Its temporary database principal now uses collision-resistant per-execution identity, best-effort cleanup on failure, and strict verified cleanup on the success path. Foundation composition must preserve those semantics together with #311’s reviewed-byte/transitive-tree binding, dedicated non-owner process, literal PATH, env -i, disposable runtime state, live-checkout denial and quiescence controls.

#311 itself remains dbc2fcf70ba6a6883381e8526cd62c6e19ce159c stacked on #259; this is a future reconciliation requirement, not authority to ingest a mutable People branch or claim protected-base PostgreSQL GREEN now.

#314/#64 handoff advanced again: the separation capability contract now includes migration 0016_employment_separation_executor_capability.sql and exact People head 30960c55e4b36e721d282a0880e193188de5162c.

Foundation reconciliation must run the exact immutable candidate tree through both tests/test_employment_separation_postgres.sh and tests/test_employment_separation_capability_postgres.sh. The capability contract now verifies the dedicated NOLOGIN/NOBYPASSRLS owner/executor split, SECURITY DEFINER owner, executor-only function capability, no executor direct People/audit/outbox DML, an actual executor invocation reaching the governed function, and unrelated-role denial with failure-isolated temporary-principal cleanup.

Keep this as owner-neutral discovery after normal stack reconciliation. Do not import mutable #64 source, add a filename switchboard, weaken the executor/DML assertions, or treat #64’s queued/unmaterialized checks as Foundation admission.

Fresh People-owner handoff for later ordinary-forward reconciliation, without copying mutable #64 source into this Foundation stack: current #64 (fix/hire-identity-type-integrity) has added two provenance-required PostgreSQL roots, tests/test_employment_separation_postgres.sh and tests/test_employment_separation_capability_postgres.sh, plus migrations 00140016. Its legacy protected-base workflow still uses the historical filename array and therefore does not execute either separation root, even though Foundation-pack validation now recognizes them as required artifacts. Current workflow evidence: the array ends at test_job_analysis_snapshot_postgres.sh.

When #259/#311 normally integrate and #64 later non-force adopts protected Foundation truth, #311's owner-neutral discovery should pick up these two roots from the exact candidate tree rather than adding another filename switch. Preserve the #311 boundaries: immutable exact-candidate tree, reviewed bytes/transitive inputs, literal PATH, env -i, dedicated non-owner, disposable HOME/TMPDIR/XDG, live-workspace traversal denial and quiescence. Do not import #64's legacy switchboard merely to make the new contracts run.

There is also a small grammar/validation dependency on #64: Foundation validation on the active People branch was advanced so schema-qualified public.* migration objects are recognized while sealing migrations 00140016. Treat that as an integration delta to adopt/adapt after protected People truth, not as authority to overwrite this stack now.

People owner #64 now has an additional PostgreSQL companion that should be reconciled by the canonical Foundation registry after the #64/#311 histories normally meet; please do not add a filename-specific workflow branch.

Current #64 exact head after traceability is fbcaee1f0c8e8012e6013b27568400bb631e6785 (base develop@eb9757f8649aaad026a9865508d9aad50c1a7a4f). New artifact:

  • root to register when the People slice is present: tests/test_employment_separation_postgres.sh
  • existing separate capability root: tests/test_employment_separation_capability_postgres.sh
  • companion of the separation root: tests/test_employment_separation_distinct_key_concurrency.sh (introduced at a67ed4b1afec755356d1cb4149007bfabaf10090)

The companion intentionally does not end in _postgres.sh, because it assumes the separation root has already migrated and seeded the shared contract database. It adds one isolated Employment fixture, holds the first successful mutation at a shell-controlled FIFO pre-commit boundary, then races a second backend with a different idempotency key against the same expected Employment version. Acceptance requires a real pg_blocking_pids(...) blocker with wait_event in transactionid|tuple (not advisory), one winner, a stale-version loser, and exactly one separation/audit/outbox/idempotency truth with zero durable losing-key idempotency row.

Please bind it through the existing reviewed companion registry/digest model and immutable exact-candidate-tree execution. Until that normal reconciliation and exact-head PostgreSQL execution occurs, #64 is explicitly not claiming hosted GREEN for this companion.

  • root: tests/test_employment_separation_postgres.sh
  • separate root: tests/test_employment_separation_capability_postgres.sh
  • companion of separation root: tests/test_employment_separation_distinct_key_concurrency.sh
  • companion of separation root: tests/test_employment_separation_failure_cleanup.sh

The new failure-cleanup companion intentionally depends on root-created schema/tenant/Person truth and must execute in the same isolated database after the root. It establishes a real distinct-key Employment blocker, terminates loser then pre-commit winner, waits both clients, requires both named PostgreSQL backends to disappear from pg_stat_activity, and proves no separation/audit/outbox/idempotency residue plus restoration of the original current Employment version.

Do not copy mutable #64 source into #311 now. This is a reconciliation handoff only; #311 remains the canonical registry/exact-tree execution owner after normal stack integration. Reviewed companion digest binding, env -i, literal PATH, dedicated non-owner, exact-candidate tree and process-quiescence controls remain required.

Reconciliation-only People handoff; no Foundation source write requested before normal stack integration.

Canonical #64 now has a third same-database companion at c099e367f80843910face46c45d4c02b1ee0ce51: tests/test_employment_separation_uncertain_commit_recovery.sh (introduced at 07cf1143906125dec527bd4272a5ff9c5746baf0). After the #259/#311 Foundation stack normally reaches protected truth and #64 ordinary-forward adopts it, register this file as a reviewed companion of tests/test_employment_separation_postgres.sh, together with test_employment_separation_distinct_key_concurrency.sh and test_employment_separation_failure_cleanup.sh. Keep test_employment_separation_capability_postgres.sh as the separate capability root.

The new companion must run in the same disposable exact-candidate DB after the separation root. Its acceptance is a true uncertain-commit path: externally observe separation/idempotency/audit/outbox commit while the first backend remains alive, terminate that backend so the original caller fails after commit, then retry on a fresh connection and recover the exact first terminal version + DB-owned recorded_at with no retry-only audit/outbox rows. Please preserve #311's immutable-tree/digest/env/non-owner/quiescence controls and do not add a filename-specific legacy workflow branch.

Foundation reconciliation handoff from People #64 current head 0d0b18ef9204077463d044073c92722d455dcd14.

A new PostgreSQL root now owns the cross-command invariant between Assignment INSERT and Employment separation: tests/test_assignment_separation_serialization_postgres.sh, with production migration database/migrations/0017_assignment_employment_separation_serialization.sql. The root exercises both commit orders with real PostgreSQL sessions, pg_blocking_pids(...), and transactionid|tuple wait evidence; it also verifies the half-open historical boundary case.

Please admit it through #311's generic exact-candidate discovery rather than another filename switch. It should remain an independent root, not a companion of test_employment_separation_postgres.sh, because it builds two isolated Employments and verifies a cross-command trigger/capability boundary. Migration 0017 creates the dedicated cluster-global orgmetra_assignment_employment_guard_owner role with a collision preflight; therefore this root needs the same disposable-cluster / role-lifecycle discipline already used for capability-bearing roots. Do not copy mutable #64 source into #311: reconcile after normal prerequisite integration and bind reviewed exact-tree digest/provenance then.

Existing separation ownership remains: separation root + capability root, with distinct-key/failure-cleanup/uncertain-commit companions. No Foundation workflow source was changed from #64.

Reconciliation handoff from active People owner #64: the generic Employment repair now uses the current tenant-qualified person_record row as the conflict anchor instead of recruiting candidate_worker_conversion_record, then reads the Employment portfolio in the following READ COMMITTED statement. The remaining real-DB acceptance for this invariant should be a same-Person / different-idempotency-key two-session companion that observes the second backend actually blocked on the Person row (not advisory-key serialization or timing-only sleep), commits the winner, then proves the loser sees the fresh Employment portfolio and fails overlapping exclusivity without a second Employment/audit/outbox/idempotency fact. Please admit/discover that companion through #311's immutable exact-candidate-tree model after its prerequisite stack integrates; do not copy mutable #64 source or add another filename-specific legacy switchboard branch.

PostgreSQL Foundation owner handoff from #64/#315: canonical docs now explicitly name the active Employment-separation acceptance set. After prerequisite Foundation integration and ordinary-forward adoption, generic discovery should execute tests/test_employment_separation_postgres.sh with its same-database distinct-key concurrency, failure-cleanup/session-quiescence, and uncertain-commit recovery companions, plus tests/test_assignment_separation_serialization_postgres.sh. The docs explicitly state that #64's legacy filename switchboard GREEN is not evidence that these specialized roots/companions passed. Preserve #311's immutable candidate tree, reviewed digest, dedicated non-owner, env -i, literal PATH, workspace isolation and quiescence controls; do not copy People domain truth into Foundation ownership.
