Exact current vertical slice

Exact head eebf6ddf8eb8403c5c67c2ce4c0c9dd27c79f8b9 targets protected main 183331e1054fb14b4c017e77fcd0aae99e949277. It adds an execution-neutral composition that binds the existing same-session stored PostgreSQL dry-run attempt capability to exact worker-attempt lease and heartbeat ownership. The resulting handler is compatible with the UUID-only signal consumer but is not registered at startup and gains no sandbox provisioning or apply authority.

The composition RED predecessor a3ed0a9ac3e3046134512545e338cfbd93d2502a failed backend pytest collection because the entry point was absent. Review then found stale doctoring paths, a contradictory UML maturity label, and narrow test-lint defects. Documentation-contract RED head 4a1aeeddb92b5c34f8e2ef0e8c32bed1db467ff2 failed backend pytest; an intermediate rename exposed one stale fixture reference, which the final head corrects.

On the exact head, repository CI, Security Scan, SAST Semgrep, frontend/backend, Valkey, and PostgreSQL 14–18 dual-lease acceptance all pass, with zero unresolved review threads. Organization Strix is still running and qualifying independent approval is absent; neither merge nor readiness is claimed.

Same-authority durable/provider composition

Exact head 745d4ec64b70dea28592765bd08f9b75daabe9ae adds make_stored_postgres_durable_dry_run_attempt_handler, the bounded repository composition that binds durable run metadata and credential-bearing stored-target lookup to the same session factory. A consumer that supplies a different factory fails with one fixed error before metadata or target I/O. The isolated sandbox factory remains injected; application startup/consumer registration, deployed sandbox lifecycle, and apply authority remain Planned. PostgreSQL 14–18 recovery acceptance now enters through this production composition; the existing predecessor-crash wrapper and private-CI loopback connector remain explicit test-only seams.

TDD evidence: provider tests first failed at collection because the composition entry point did not exist, and the canonical documentation contract then failed because the new boundary was absent. After the narrow implementation and documentation graph update, 46 focused production/stage/documentation tests pass; the full backend suite passes 1,112 tests with 10 environment skips; mypy passes 87 source files; compileall and git diff --check pass. CodeGraph remained unavailable in the execution environment, so impact inspection used repository-wide rg plus focused and full tests. Exact-head GitHub CI/security/review results remain authoritative.

Post-connect exact-target revalidation

Exact head 420593cfcd8f98efdbddf5c72536e16b01466a91 repeats the exact guarded encrypted target/snapshot/attempt lookup after DNS/SSRF/TLS-pinned connection acquisition and requires an identical result before any target read. A mismatch or invalidated run/cancellation/lease closes the acquired connection without yielding capture authority; failures remain fixed and non-reflecting. Exact attempt leasing and fresh worker-state checks remain required because concurrent metadata change after the second check is not claimed impossible.

TDD evidence: the focused provider test first observed only one metadata lookup and incorrectly yielded a connection after the stored target changed. After the narrow fix, 41 focused provider/documentation contracts pass; the full backend suite passes 1,111 tests with 10 environment skips; mypy passes 87 source files; compileall and git diff --check pass. CodeGraph was unavailable in the execution environment, so impact inspection used repository-wide rg plus focused and full tests. Exact-head GitHub CI/security/review results remain authoritative.

Stored-target provider PostgreSQL 14–18 acceptance

Exact head d63e457082f3701587f219c19e06076b5d4dfbc7 replaces the durable recovery matrix's hand-built live reader with make_stored_postgres_live_preflight_factory. Each PostgreSQL 14–18 cell stores the restricted target as real AES-GCM ciphertext, resolves the exact active attempt and succeeded snapshot scope, decrypts only after that guard, captures through the same acquired connection, closes it, and resumes after predecessor lease expiry without replaying committed sandbox DDL.

The first exact-head matrix run supplied the sandbox's deliberately quoted, whitespace-bearing schema name as the persisted SnapshotCreateIn.schema_filter. All five versions correctly rejected it at the existing unquoted schema-filter contract before credential release, and the durable worker exposed only the fixed live-stage failure. The smallest remedy separates the valid unquoted target filter from the hostile sandbox schema name; production validation and the DNS/SSRF guard remain unchanged.

The matrix substitutes only the connector with an explicit test-only loopback seam because the production DNS/SSRF guard correctly rejects the private CI target. This evidence does not prove unmodified guarded-route integration, deployed credentials/network identity, startup wiring, process recovery, SQL apply, or production readiness.

TDD evidence: the canonical composition contract first failed because the matrix did not reference the provider; then the real PostgreSQL 14–18 matrix failed uniformly at the invalid stored schema-filter boundary. After the bounded fixture correction, 36 focused tests pass with 8 environment skips and 10 provider/metadata tests pass. The full backend suite passes 1,110 tests with 10 environment skips after clearing inherited proxy variables; mypy passes 87 source files; compileall and git diff --check pass. The corrected real PostgreSQL cells require exact-head GitHub GREEN evidence.

Guarded stored-target live-preflight provider

Exact head 6a78f1e0d33bdd178ec33ede07a2c1417b8bc7bc adds a repository-level provider factory for the bounded read-only live-preflight stage. It invokes the exact live-attempt/snapshot/connection lookup before decryption, opens only that stored PostgreSQL target through the existing DNS/SSRF/TLS guard, binds snapshot capture to the identical acquired connection and validated schema scope, closes the target on every path, propagates process-control cancellation, and emits fixed non-reflecting acquisition/cleanup failures. A follow-on regression also proves that a metadata context exit cannot leak a DSN-bearing worker exception.

The provider accepts no SQL and grants no apply authority. It is deliberately not wired into application startup or an attempt consumer. Provider-backed PostgreSQL 14–18 acceptance, deployed least-privilege credentials/network identity, process isolation, worker operations, and all live apply/recovery/convergence work remain Planned.

TDD evidence: collection first failed because the provider module did not exist; a focused acquisition failure then exposed the missing cancellation dependency import; and the UML contract failed on stale provider maturity text. After the narrow fixes, the full backend suite passes 1,109 tests with 10 environment skips; mypy passes 87 source files; compileall and git diff --check pass. The existing PostgreSQL 14–18 matrix remains provider-neutral test evidence and does not yet prove this stored-target composition.

Exact succeeded base-snapshot scope

Exact head 6a78f1e0d33bdd178ec33ede07a2c1417b8bc7bc tightens the guarded encrypted-target lookup before any future provider composition. Its one metadata statement now joins the immutable plan's exact base snapshot and requires that snapshot to be succeeded, completed, and owned by the same project and stored connection. The secret-safe result binds the encrypted DSN bytes to base_schema_snapshot_uuid and the validated optional schema_filter; credential bytes and schema scope are excluded from its representation.

Missing, unfinished, cross-scope, malformed, or non-succeeded snapshot metadata fails with the existing fixed non-reflecting error. This performs no decryption, route selection, target connection, SQL, startup wiring, or apply.

TDD evidence: two focused tests failed at the prior two-column resolver boundary, then 11 focused tests passed with 8 environment skips. The full backend suite passes 1,105 tests with 10 environment skips; mypy passes 86 source files; compileall and git diff --check pass. The real PostgreSQL 14–18 matrix is environment-skipped locally and remains exact-head CI evidence.

Secret-safe pre-dependency legacy validation

Exact head f414494880babbada5e075e6ba3ecf577a1411e7 closes the request-order gap identified while sweeping superseded PR #879. FastAPI previously executed get_current_user and get_session before reporting an invalid ApplySqlIn body. The narrowly scoped SecretSafeLegacyApplyRoute now validates only the legacy apply body first and returns the existing fixed non-reflecting 422 for malformed, missing, oversized, or control-bearing input. The global sensitive-body handler remains defense in depth and never serializes RequestValidationError.body.

This does not authorize SQL, broaden the legacy parser, enable persistent apply, or alter the structured forward-engineering path. The existing multiline/comment fixtures already exceed #879's two minor test findings; the canonical doctoring record now adds request ordering, monitoring/rollback, and academic secure-logging traceability without duplicating documentation.

TDD evidence: the focused production-router test first observed both auth and session calls, then passed with neither invoked. 140 focused tests and the full backend suite (1,105 passed, 10 environment skips) pass; mypy passes 86 source files; compileall and git diff --check pass.

Guarded encrypted live-target lookup

Exact head 8cd356f0844680a689650add3f8b4f0a0f77e270 adds load_guarded_live_preflight_target. One metadata query reuses the canonical live run/plan/project/active-attempt/cancellation/state-version/lease/digest/expiry predicate and joins the exact project-owned db_connection before releasing only the encrypted DSN ciphertext and 12-byte nonce. The frozen result excludes both byte strings from repr; missing, duplicate, malformed, or driver-failed lookups expose one fixed non-reflecting error while cancellation propagates.

This boundary performs no decryption, route selection, target connection, startup/provider composition, SQL, or apply. The PostgreSQL 14–18 recovery scenario now uses the lookup before the constrained test reader and expects an expired predecessor attempt to fail closed; that exact-head matrix remains authoritative.

TDD evidence: the focused suite first failed at import because the resolver did not exist. After implementation, 11 focused worker/documentation tests and the full backend suite (1,103 passed, 10 environment skips) pass; mypy passes 86 source files; compileall and git diff --check pass. The real PostgreSQL case is environment-skipped locally and must pass exact-head CI.

DBML identifier-to-DDL and resource boundary

Exact head d972afaf53995e9319ed1df86d624150350dd61c closes the implemented portion of security issue #747 without adding apply authority. The DBML parser now decodes doubled quotes, validates every imported PostgreSQL identifier losslessly (non-empty, no NUL, at most 63 UTF-8 bytes), rejects ambiguous dotted paths and malformed quoted references, strips comments only outside quotes, and routes PK/FK identifier rendering through the dialect-owned quote helper. Stable hash-suffixed derived identifiers avoid PostgreSQL's silent truncation boundary.

Direct parser calls now share the authenticated route's 524,288-character bound, add a 10,000-line and 4,096-character-per-line bound, and fail closed before unbounded work. The sensitive DBML validation route returns a fixed non-reflecting 422. A real PostgreSQL 14–18 integration case executes hostile-looking quoted schema/table/column names in the isolated sandbox and verifies only the intended relation exists; it is test evidence, not production apply readiness.

This two-parent commit records superseded performance PR #746 exact head 02d4c97e47945039ef501574959737e7dd48892c as its second parent and preserves its O(N) per-relation column counter plus 1,000-column/multi-relation regression. #746 is closed as a duplicate lane; its history is not rewritten.

TDD evidence: malformed/doubled/oversized identifiers, ambiguous paths, quote-aware comments, derived-name bounds, total/line resource bounds, and non-reflecting HTTP validation all failed at their intended boundaries before implementation. Focused verification passes 62 tests with 9 environment skips; mypy passes 86 source files; the full backend suite passes 1,099 tests with 10 environment skips; compileall and git diff --check pass. Exact-head GitHub CI, security, PostgreSQL-version, and independent review results remain authoritative.

Multiline SQL transport integrity

Exact head 8713dce150b5bbb3c676f7cd0b0edbba40f95fdd closes accepted security issue #764 at the request-schema/HTTP boundary. ApplySqlIn.sql preserves tab, LF, CR, Unicode text, and the existing 262,144-character limit while rejecting NUL, DEL, and every non-text C0 control. Validation failures on the sensitive legacy route return one fixed 422 without reflecting the SQL body or embedded secret-like literals; other routes retain FastAPI's standard validation handler. The conservative DDL parser remains the authorization boundary, so this is transport/log-integrity hardening rather than an SQL-injection claim.

TDD evidence: collection failed because the secret-safe handler did not exist, then the exhaustive schema/HTTP boundary suite passed 115 tests. Mypy passes 86 source files; the full backend suite passes 1,082 tests with 9 environment skips; compileall and git diff --check pass. Exact-head GitHub CI/security/review results remain authoritative.

Default-deny legacy persistent apply

Predecessor c2c3d98fe1c61f5719228ef5434648278ebfefd8 added a default-false LEGACY_PERSISTENT_APPLY_ENABLED operator switch. Persistent dry_run=false compatibility requests still require deployer authorization, but now fail with a fixed 403 before stored-target lookup, credential decryption, connection opening, or SQL execution unless an operator explicitly opts in. Rollback-only validation and the endpoint request/response shape remain available. This contains new legacy requests; it is not structured apply authority, an in-flight rollback guarantee, or a retirement decision.

Predecessor TDD evidence: the new target-access boundary failed before implementation. The 47 focused API/documentation/traceability contracts, mypy across 85 source files, full backend suite (983 passed, 9 environment skips), compileall, and git diff --check pass locally. Exact-head GitHub CI/security/review results remain authoritative.

Predecessor CI remediation

Predecessor 85bcd7c2f71d3c645431623705a97a02a109696f remedied the first failing boundary from repository CI run 31801281778: mypy 2.3 inferred one reused loop local as two incompatible query types, and TypeScript 6 rejected two non-UUID crypto.randomUUID() fixtures. Distinct typed locals and valid deterministic UUID fixtures restore both type contracts without changing runtime behavior. Full verification then exposed and fixed three stale asynchronous test assumptions: diagram search now waits for the selected project's snapshot load, modal polling has a bounded 3-second observable-state wait under parallel suite load, and live preflight asserts the sandbox-completion state version carried by the refreshed handoff.

Predecessor local GREEN evidence: mypy app passes 85 source files; 56 focused backend tests pass; the full backend suite passes 982 tests with 9 integration/environment skips; frontend typecheck passes; two consecutive full frontend runs each pass 264 tests; the production build, compileall, and git diff --check pass. The local Clearfolio proxy-only failures disappeared when inherited sandbox proxy variables were removed. Exact-head GitHub CI/security/review results remain authoritative and all predecessor-head checks are historical.

Implemented at this head

  • Server-authoritative versioned schema models/revisions and immutable, target-bound structured migration plans.
  • Fail-closed PostgreSQL snapshot capability boundary and deterministic compiler/risk/precondition semantics.
  • Durable migration run/event/outbox/attempt foundations, exact versioned cancellation, terminal acknowledgement, lease-bound recovery primitives, UUID-only Valkey signaling, and an execution-neutral PostgreSQL/Valkey dual-lease consumer contract.
  • Isolated PostgreSQL dry-run execution/convergence core and bounded same-transaction read-only live-preflight primitive.
  • Execution-free deployer confirmation/apply-intent persistence; it creates no dispatch, credential access, target connection, SQL execution, or DDL authority.
  • Typed browser plan review, exact-digest dry-run intent, verified run polling/audit, cancellation intent, exact-target apply-intent confirmation, and accessible modal orchestration.
  • PostgreSQL, MySQL/MariaDB, and Snowflake connection creation runs the existing dialect target guard before credential encryption or metadata persistence. Rejected DSNs return a fixed 422; live connection paths retain independent target validation. Deployment-level egress enforcement remains absent and is not claimed.
  • Provider-neutral durable dry-run orchestration applies independent whole-stage cancellation deadlines to sandbox and live-preflight acquisition, execution, and snapshot capture. For cooperative providers, timeout cancellation awaits async capability cleanup and exposes only a fixed stage failure.
  • Canonical Architecture, PRD, TRD, ADRs, UML, ERD/data model, contracts, threat model, runbook, test strategy, standards, security checklist, and changelog track this partial boundary.

Provider-callable live-preflight handoff guard

Predecessor head 8428d99be700f56bbe8c67fe0fcd9dde7a9f67b6 adds a server-owned, execution-neutral guard that a future concrete provider can call immediately before resolving the stored target. One fresh metadata statement fails closed unless the exact run, plan, project, stored target, active unexpired attempt UUID/number, uncancelled live_preflight_running state/version, plan digest, and plan expiry still match. It returns no credential, route, connection, plan JSON, or SQL; query failures expose only a fixed error.

The PostgreSQL 14–18 matrix now invokes the guard before the test provider opens its constrained target, rejects the interrupted first attempt at the exact one-second lease-expiry boundary, and accepts the exact successor attempt. This is an implemented guard primitive with ephemeral database acceptance, not deployed target authority. No concrete provider invokes it yet, and it does not eliminate the observation-to-target-open gap. Credential/route binding, startup wiring, provider composition, target access, and apply remain Planned.

TDD evidence: the intended API assertion failed before implementation and the documentation maturity contract failed before canonical text was aligned. The single-query AST boundary, falsey/naive timestamp rejection contract, all five durable-worker documentation contracts, compileall, and git diff --check pass locally. Current-head local verification is reported in the CI-remediation section above; exact-head GitHub backend and PostgreSQL jobs remain authoritative.

Exact live-preflight handoff input

Exact head 2cf71c5a0073bd7e9119bd699c3fbc910acc0d3b extends the identifier-only LivePreflightRequest with the server-refreshed expected run state version. A future provider can therefore compare the precise metadata state it is asked to honor alongside the stored target and durable attempt UUID; the request still carries no plan JSON, SQL, DSN, credential, PostgreSQL major, or digest data. Atomic provider-side state/attempt validation, concrete credentials/routes, startup wiring, live apply, and readiness evidence remain Planned.

TDD evidence: an AST/contract assertion failed before the field existed, then the dependency-stubbed request harness and all five durable-worker documentation contracts passed. compileall and git diff --check pass. Offline native pytest resolution remains blocked by an uncached aiohttp wheel, so exact-head GitHub CI and PostgreSQL 14–18 jobs are authoritative.

Review cleanup

Exact head a2b3e7719f4c164f47456577da3c1cda2cb4acb7 documents both best-effort rollback guards so cleanup failures cannot be mistaken for silently ignored success. The handlers still preserve the original cancellation/shutdown or target failure. py_compile, compileall, source-count verification, and git diff --check pass locally; native pytest dependencies are unavailable in this sandbox, so exact-head CI remains authoritative.

Cancellation-boundary correction

The predecessor documentation overstated asyncio.wait_for as forcibly bounding a “hung” capability context. In Python 3.10-compatible in-process execution, wait_for requests cancellation and waits for the task; it cannot forcibly terminate a provider that suppresses CancelledError or blocks during cleanup.

Predecessor 106dbcbeb1f7a3436a50d535b642b63dddfc1ba6 made that authority limit explicit and machine-checkable:

  • injected providers must use cooperative cancellation and must not suppress CancelledError;
  • current tests prove cancellation and cleanup only for conforming providers;
  • process isolation and an external kill boundary remain Planned deployment requirements;
  • no hard wall-clock termination, provider, credential, network, startup, or production-worker claim is made.

Predecessor da17cbe7668deee0d97237ffaa33aa43d8de180d added a deterministic non-cooperative-provider test. It observes the configured deadline request cancellation while the handler and capability remain live, then proves cleanup and a fixed secret-safe failure occur only after the provider releases. This is negative boundary evidence, not provider conformance or process-isolation evidence.

PostgreSQL 14 CI RCA and remedy

Exact-head job 94687317007 failed before tests. The first pg_isready succeeded against the official image's temporary initialization server; the entrypoint restarted PostgreSQL between fixture-creation commands, and the second docker exec psql encountered a missing socket.

This head adds a RED/GREEN workflow contract and waits for the official PostgreSQL init process complete; ready for start up. marker before probing the final server. The startup shell block passes bash -n. No gate was weakened or skipped.

PostgreSQL 15 lock-observation RCA and remedy

Exact-head job 94690827697 executed the real preflight timeout successfully but its subsequent lock-wait observer never saw pg_stat_activity.wait_event_type = 'Lock'. The observer was the same connection and explicit transaction that held the blocking lock; PostgreSQL may cache that transaction's first statistics snapshot, so an early non-wait observation could remain stale through the bounded poll.

A RED documentation contract now requires pg_stat_clear_snapshot() before the statistics view. The integration test clears the transaction-cached statistics snapshot before every observation, preserving the real lock, bounded timeout, backend termination, fixed error, and connection-state assertions. Focused contract, full backend (921 passed, 8 skipped), mypy (83 source files), and diff checks pass locally. Docker is unavailable locally, so the new exact-head PostgreSQL 14–18 matrix remains the authoritative real-server GREEN evidence.

Frontend CI RCA and remedy

Exact-head frontend CI then exposed two orchestration-test races: one queried diagram actions before asynchronous rows rendered; the other rejected predecessor project requests before React had installed the successor effect and cleanup. The immediate predecessor had passed and no frontend production code changed.

This head synchronizes the tests on their actual UI/effect boundaries. Both cases passed 10 consecutive focused runs; all 37 test files / 259 tests, typecheck, and production build pass. Behavior assertions remain intact.

Backend documentation-contract RCA and remedy

Predecessor exact-head backend job 94719966858 ran the full suite and exposed two machine-checkable documentation drifts after 951 passed, 9 skipped: docs/STANDARDS.md no longer contained the exact implemented live-preflight/isolated-executor maturity sentences, and docs/TEST_STRATEGY.md omitted the exact Planned real-target-lock-acquisition boundary. The code and PostgreSQL 14–18/Valkey/frontend jobs passed independently.

This head restores those canonical evidence statements without weakening a gate. The three focused documentation contracts, ten direct manifest contracts, compileall, and git diff --check pass locally. The new exact-head GitHub suite remains authoritative and pending.

Deterministic pre-apply lock-plan compiler

Exact head c8c9019810bee68bbdeb7001e62fe1dcae9afb7e adds an execution-neutral compiler for the future apply lock boundary:

  • consumes only the immutable structured plan contract; it parses no SQL;
  • validates executable/unblocked transactional statements and reviewed ACCESS EXCLUSIVE risk metadata;
  • preserves PostgreSQL quoted mixed-case/Unicode identifiers;
  • deterministically sorts and deduplicates pre-existing table targets while excluding newly created objects;
  • fails closed for unknown kinds, tampered lock modes, invalid identifiers, non-transactional statements, and oversized plans.

This compiler does not connect to a target, acquire locks, dispatch work, execute SQL/DDL, revalidate drift or privileges, or grant apply authority. Those stages remain Planned.

Signed pre-apply revalidation manifest

Exact head c8c9019810bee68bbdeb7001e62fe1dcae9afb7e adds a target-free manifest for the future in-lock revalidation boundary:

  • verifies the exact persisted plan digest, strict compiler-v1 plan shape, exact compiler/snapshot capability versions, and supported PostgreSQL major;
  • binds supported PostgreSQL major and base/target digests to deterministic existing-table lock targets, structured boolean data checks, and zero segments for no-op work or one ordered all-transactional segment for non-empty compiler-v1 work;
  • maps compiler-v1 operations to structured database CREATE, schema CREATE, and table OWNER requirements, rejecting weaker, unknown, reordered, or duplicated privilege labels;
  • rejects tampering, unknown contract fields, unsupported versions, cross-table preconditions, and any precondition whose table is not covered by its statement lock;
  • opens no target connection, acquires no lock, captures no snapshot, checks no privilege, dispatches no work, and executes no SQL or DDL.

The PostgreSQL 14–18 matrix now contains test-only acceptance that acquires the compiled quoted table lock, observes a concurrent insert time out, runs the bound table-empty check while holding the lock, rolls back, and then observes the insert succeed. This is ephemeral compiler/semantics evidence only. Production target connection/lock orchestration, fresh snapshot capture, apply-time drift/privilege/data checks, transactional execution, and recovery remain Planned.

Parameterized PostgreSQL privilege probes

Exact head c8c9019810bee68bbdeb7001e62fe1dcae9afb7e re-derives the manifest from the exact signed plan and expected digest, then compiles only its exact structured privilege requirements into fixed read-only PostgreSQL catalog queries:

  • database CREATE uses has_database_privilege;
  • schema CREATE uses a parameterized has_schema_privilege query;
  • ordinary-table OWNER uses a parameterized catalog lookup and pg_has_role(..., 'USAGE') so immediately usable owner-role authority is tested without rendering identifiers into SQL;
  • a redirected or otherwise tampered plan fails digest validation before any query is compiled.

The existing PostgreSQL 14–18 matrix now executes the table-owner probe as the owner and as the independently constrained read-only role, expecting true and false respectively. That exact-head matrix is pending. The compiler itself opens no connection, executes no query, observes no target role, proves no lock/freshness, and grants no apply authority.

Signed-plan privilege-probe binding correction

CodeRabbit's exact-head review identified that a frozen manifest dataclass remained publicly constructible and replaceable: a caller could supply a structurally valid table OWNER requirement for a different object and redirect the compiled probe. A RED regression demonstrated the valid-position/valid-scope redirect.

This head removes caller-built manifests from the public probe compiler. It accepts the exact structured plan plus expected digest, re-derives the manifest through the signed-plan validator, and only then compiles fixed parameterized catalog reads. The redirected-target regression is GREEN, all 33 focused cases and 29 documentation contracts pass in the dependency-stubbed local harness, compileall and git diff --check pass, and no native pytest or real-PostgreSQL GREEN is claimed locally. Exact-head GitHub CI remains authoritative.

Manifest-bound observation assessment

Exact head c8c9019810bee68bbdeb7001e62fe1dcae9afb7e adds a pure, execution-neutral assessment for future in-lock observations:

  • accepts only the exact manifest plan digest and one complete ordered result row for every structured privilege requirement and precondition;
  • rejects missing, extra, renamed, reordered, differently targeted, or non-boolean evidence;
  • derives explicit base-match, privilege-satisfied, and precondition-satisfied facts, preserving drift/denial/failure as negative evidence;
  • opens no target connection, captures no target state, proves no freshness, connection identity, or held lock, and grants no apply authority.

Production capture, credential/connection binding, target lock acquisition, same-connection revalidation, DDL execution, rollback, and recovery remain Planned.

Same-connection pre-apply observation capture

Exact head c8c9019810bee68bbdeb7001e62fe1dcae9afb7e adds a bounded caller-owned target observation primitive without adding apply authority:

  • re-derives the manifest and privilege probes from the exact signed plan and expected digest before target access;
  • starts one read-only repeatable-read transaction, applies a bounded transaction-local statement timeout, and captures the strict snapshot plus every fixed privilege probe and structured precondition in manifest order on the same connection;
  • treats cast-data failure as explicit negative evidence inside a savepoint, rejects non-boolean or incomplete evidence, and returns only the pure non-authorizing assessment;
  • rolls back on failure, preserves cancellation/process signals after best-effort cleanup, and exposes a fixed secret-safe diagnostic for callback/driver failures;
  • owns no credential, stored-target identity, durable attempt, advisory/object lock, dispatch, SQL rendering, DDL, or apply authorization.

The new PostgreSQL 14–18 matrix case composes snapshot capture, table-owner privilege, and a negative table-empty fact on the real fixture connection. It is queued exact-head evidence, not a local or production-readiness claim. Production stored-target/attempt credential binding, lock acquisition, in-lock repetition, executor transaction/rollback, and recovery remain Planned.

Exact-head review remediation

Exact head a2b3e7719f4c164f47456577da3c1cda2cb4acb7 addresses the still-valid findings from CodeRabbit's predecessor-head review without adding live apply authority:

  • run polling invalidates stale consumer evidence on failure;
  • exact passed dry-run evidence remains separate from the active apply-intent audit run;
  • target names are trimmed, whitespace-only names fail closed, ambiguous retries preserve one idempotency key, and an explicit new-registration action unlocks correction under a fresh key;
  • pre-apply capture rejects non-boolean privilege evidence and all positional zip checks are strict;
  • real-PostgreSQL fixtures delete apply references before dry runs and close every partially acquired connection;
  • the Snowflake checklist no longer claims unproved transport IP pinning, and the worker contract records the non-atomic target-capability handoff as Planned rather than implemented;
  • TRD maturity/traceability and the frontend changelog are aligned with the live code.

Focused local evidence: 43 dependency-stubbed capture cases, 29 documentation contracts, 5 durable-worker documentation contracts, 2 TRD traceability contracts, 3 malformed lock-plan assertions, compileall, and git diff --check pass. Native frontend tests were not run locally: the exact dependency tarball was absent from the offline cache and the available Node 24 runtime is below the repository's Node 26 requirement. Exact-head GitHub CI is authoritative for frontend and real PostgreSQL 14–18 evidence. All 18 replacement blobs in published Git tree b28fe500109d3f2b59b32c0a3c18c45d22d83f1e exactly match the locally verified files and preserve unrelated parent blobs. The successor additionally retires prior dry-run evidence whenever a new dry-run request is accepted; both replacement blobs in Git tree bd55b2b2b379bbed42666a473144c3ea93568dc5 exactly match the locally verified files.

Current-head evidence

The stage-timeout implementation at predecessor 0bd8a6d6ad229621de2619a025594dbbb963c3f2 was developed test-first: three RED failures preceded the worker implementation.

The authority correction at predecessor 106dbcbeb1f7a3436a50d535b642b63dddfc1ba6 added a RED documentation-contract assertion, then aligned the worker contract, PRD, TRD, forward contract, runbook, changelog, and implementation docstring.

  • Focused worker/documentation suite: 42 passed.

  • Focused worker failure/documentation suite at this head: 13 passed.

  • PostgreSQL startup regression contract: 3 focused tests passed.

  • Full backend suite: 921 passed, 8 skipped.

  • Frontend: 37 files / 259 tests passed; typecheck and production build passed.

  • Backend mypy: 83 source files passed.

  • git diff --check: passed.

  • Apply-lock boundary RED: importing the not-yet-created module failed with ModuleNotFoundError before implementation.

  • Compiler-version RED: a future compiler_version was accepted before the successor fix.

  • Apply-lock production assertions, including exact-version acceptance and missing/future-version rejection, documentation contract, compileall, and git diff --check: passed locally.

  • Runbook-drift RED: the canonical maturity row omitted compiler-version rejection; its machine-checkable documentation contract and aligned maturity text now pass.

  • Pre-apply manifest RED: importing the not-yet-created module failed with ModuleNotFoundError before implementation.

  • Signed-manifest pure-function assertions cover the happy path, digest tampering, capability-version/proposal rejection, cross-table rejection, zero no-op segments, and one ordered multi-statement transactional segment; aligned documentation assertions, compileall, and git diff --check pass locally.

  • Privilege-manifest RED proved the structured scope was absent; the narrow implementation and manual assertions now cover table OWNER, database/schema CREATE, invalid-label rejection, quoted/Unicode identifiers, aligned documentation, compileall, and git diff --check. Local pytest/ruff remain unavailable and are not claimed.

  • Privilege-probe RED: the intended compiler lookup failed with AttributeError before implementation.

  • Pure-function assertions cover exact database/schema/table query shape, identifier parameters, strict signed-plan composition, and rejection of a redirected table target under its stale digest. Real PostgreSQL 14–18 owner/denied-role GREEN is pending exact-head CI and is not claimed locally.

  • Observation-assessment RED: after stubbing unavailable local dependencies, the intended API lookup failed with AttributeError before implementation.

  • The focused manifest/assessment/probe harness covers 33 cases including complete, drifted, denied, failed, missing, mismatched, and non-boolean evidence; all 29 documentation contracts, compileall, and git diff --check pass locally. The local environment still lacks pytest/asyncpg, so no native pytest run is claimed for this slice.

  • Exact-head PostgreSQL 14–18 acceptance adds a test-only compiled-lock/concurrent-insert/bound-check/rollback sequence; its GitHub matrix is pending, so no real-server GREEN is claimed yet.

  • The local dependency environment could not install or run pytest because package-index DNS was unavailable; no local pytest GREEN is claimed for this new slice. Exact-head GitHub CI is authoritative.

  • All 15 changed blobs in published Git tree 61e0dfda5c0fcc2dfb2a1a207b44bf07e51fff96 exactly match the locally verified files. The full tree retains the live remote parent's frontend/package.json and frontend/package-lock.json; those two unrelated parent blobs differ from the older detached local base and are not claimed as locally reverified by this slice.

  • Same-connection capture RED: importing capture_pre_apply_revalidation_observation failed with ImportError before implementation.

  • The dependency-stubbed focused harness now covers 42 cases, including same-connection ordering, negative drift/privilege/precondition facts, cast-failure savepoint recovery, fixed secret-safe failure, cancellation rollback, and invalid timeout rejection. All 29 documentation contracts, compileall, and git diff --check pass locally. Native pytest/asyncpg and Docker are unavailable locally, so no native or real-PostgreSQL GREEN is claimed; exact-head GitHub CI is authoritative.

  • All 15 replacement blobs in published Git tree 51c90989fff33376839a97fda7817a2fcf39e448 exactly match the locally verified files. The tree is based on live parent c8c9019810bee68bbdeb7001e62fe1dcae9afb7e^ and preserves unrelated parent blobs.

At exact head 8713dce150b5bbb3c676f7cd0b0edbba40f95fdd, GitHub has created 20 substantive exact-head check runs; all are still queued. Exactly one valid review thread remains unresolved: no concrete deployed provider yet composes the server-owned guard atomically with stored-target resolution and target opening, so the observation-to-open race remains Planned and release-blocking. No qualifying independent approval exists. Merge remains blocked; all predecessor workflow evidence is historical only.

Explicitly still Planned / release-blocking

  • Application consumer/worker startup wiring and deployed sandbox/credential providers.
  • Disposable sandbox provisioning/materialization/isolation/cleanup, provider cancellation conformance, external process kill, and process/container restart evidence.
  • Apply dispatch/executor, pre-apply drift/privilege/precondition revalidation after locks, target transaction execution/rollback proof, timeouts, cancellation propagation, reconciliation, and semantic convergence verification.
  • Composed accessible browser edit → review → dry-run → preflight → confirm → apply/recover → audit E2E.
  • Deployment egress-policy evidence, packaging, SBOM/provenance, migration/rollback/recovery acceptance, operational acceptance, and release evidence.

The browser remains an editor/reviewer/intent surface and cannot submit arbitrary SQL authority. This PR does not establish production apply readiness, compliance, certification, or release readiness.

Latest exact-head slice

Exact head dbdee6a2ffcf7b8860f3886b0cf60612e9ee3b7e adds a query-only capture_postgres_snapshot callback for a caller-owned authorized connection and transaction. The normal DSN introspection path retains its SSRF-guarded connection and transaction ownership, while live-preflight composition can reuse the same connection for strict snapshot evidence and bounded checks.

CodeRabbit correctly identified that the predecessor allowed the optional Citus savepoint to become a top-level transaction when a caller failed to supply the required outer transaction. This head fixes that lifecycle defect test-first: the callback now fails before catalog access unless conn.is_in_transaction() is true, opens no transaction itself, and preserves the caller's transaction depth. Local supporting evidence: 91 focused tests passed; full backend 1,101 passed with 10 environment skips; mypy passed 86 source files; compileall and diff check passed. Exact-head repository and PostgreSQL-version workflows remain authoritative; predecessor evidence is historical.

This closes no credential/provider/startup/apply gate and makes no readiness claim.

Merge gates

Keep this PR draft. Do not merge until the unchanged exact head has all required CI/security gates successful, zero valid unresolved findings, and any policy-required qualifying independent approval. Local evidence is supporting only; GitHub exact-head evidence remains authoritative.

변환하는 기존 유틸리티가 있으면 재사용하고, 지원할 수 없는 default 형식은 계획을 safe로 표시하지 말고 blocker로 처리하여
fail-closed 동작을 유지하세요.
- Around line 197-238: Update the ordinal baseline used by the added-column
validation in the migration-plan logic so deleted-column gaps are not treated as
required positions. Derive the expected ordinals from the current existing
columns’ ranks, then validate each sorted added column as contiguous after that
current sequence while preserving the existing blocker structure.

In `@backend/app/models.py`:
- Around line 236-275: Enforce uniqueness for the immutable plan identity
`(schema_model_revision_uuid, db_connection_uuid, base_schema_snapshot_uuid,
statement_digest)` on `MigrationPlan`, adding an `expires_at` index if expiry
cleanup is planned, and create the required database migration. Update
`create_migration_plan` to look up and reuse an existing valid plan for the same
identity instead of inserting duplicates, while preserving server-authoritative
deterministic behavior.

In `@backend/app/pg_introspect/introspect.py`:
- Around line 169-182: Update the Citus metadata query handling around
CITUS_DISTRIBUTED_TABLES_SQL to catch InsufficientPrivilegeError,
UndefinedColumnError, and UndefinedFunctionError alongside UndefinedTableError;
roll back the savepoint and set citus_distributed_tables to an empty list for
all of these optional Citus failures.

In `@backend/tests/test_api_apply_sql.py`:
- Around line 96-116: Update
test_live_apply_requires_deployer_role_while_dry_run_requires_editor to also
invoke apply_sql with dry_run=True and assert that require_project_member is
called with minimum_role="editor"; retain the existing dry_run=False assertion
for "deployer" so both authorization paths are covered.

In `@backend/tests/test_documentation_contract.py`:
- Around line 68-81: Add concise docstrings to every public test function in
backend/tests/test_documentation_contract.py, including
test_canonical_forward_engineering_documents_exist_and_are_nonempty and the
additional public tests referenced by the comment. Each docstring should briefly
state the test’s contract while preserving the existing test logic.

In `@backend/tests/test_forward_snapshot_adapter.py`:
- Line 60: Update the pytest.raises match patterns at the shown locations to use
raw string literals, preserving the existing “recapture|required” alternation
and resolving Ruff RUF043.

In `@docs/superpowers/specs/2026-08-09-forward-engineering-design.md`:
- Line 8: Adjust the “Implementation snapshot” heading hierarchy so it follows
the preceding top-level heading: change `### Implementation snapshot` to `##
Implementation snapshot`, unless an appropriate intermediate `##` section is
intentionally added.

In `@docs/TEST_STRATEGY.md`:
- Around line 197-215: Add PR workflow security gates for osv-scan,
dependency-review, and trivy-fs under .github/workflows, including database
refresh before trivy-fs and scanning the merge ref rather than the PR head.
Update docs/TEST_STRATEGY.md to document these checks as active PR requirements
instead of deferring them to the release workflow.

Nitpick comments:
In `@backend/alembic/versions/0009_migration_plan.py`:
- Around line 62-74: Add an index on the expires_at column in the migration_plan
table alongside the existing indexes, so expiration checks and cleanup queries
can efficiently filter plans by expiry time.

In `@backend/app/api/migration_plans.py`:
- Around line 114-116: Unify plan_json access in compile_migration_plan by
defining a TypedDict return contract for the compiler output, including
proposed_statements, statements, compiler_version, blockers, and risk_summary.
Then update the surrounding accesses to consistently follow that contract, using
direct indexing when fields are guaranteed or defensive defaults when they are
optional.

In `@backend/app/forward/migration_plan.py`:
- Around line 428-432: Update the plan construction flow so each plan includes
snapshot_contract_version set from CURRENT_POSTGRES_SNAPSHOT_CONTRACT_VERSION
before _digest_plan computes its digest. Ensure the field is part of the
serialized plan body, so changes to the snapshot adapter contract produce a
distinct plan identity while preserving the existing digest inputs.

In `@backend/app/forward/schema_model.py`:
- Around line 257-264: Update the validation loop for unique_constraints,
foreign_keys, and indexes to default missing table fields to empty lists before
calling _list, matching the existing unsupported_features optional-field
behavior. Preserve validation of explicitly provided values and ensure canonical
output continues to include all three fields as empty lists when omitted.

In `@backend/app/forward/snapshot_adapter.py`:
- Around line 183-190: Update the relation_oid resolution in the index loop so
table_oid is used when relation_oid is absent or explicitly None, while
preserving a valid relation_oid when present. Keep the existing primary-key
backing-index validation in place.

In `@backend/app/pg_introspect/introspect.py`:
- Line 164: 변수 citus_distributed_tables에 명시적 타입 주석을 추가하여 빈 리스트의 요소 타입을 선언하고 mypy
strict 검사를 통과하도록 수정하십시오.

In `@backend/app/schemas.py`:
- Around line 170-184: Define dedicated Pydantic models for the structured
payload fields in MigrationPlanOut, then replace the untyped list[dict] and dict
annotations for statements, proposed_statements, blockers, and risk_summary with
those models. Preserve the existing response shape while ensuring OpenAPI
schemas and validation describe each field explicitly.

In `@backend/tests/test_api_migration_plans.py`:
- Around line 122-130: Extend
test_migration_plans_do_not_use_plan_digest_as_database_idempotency_key to also
inspect MigrationPlan.__table__.indexes for unique indexes, and assert that no
unique index covers (“project_space_uuid”, “statement_digest”). Keep the
existing UniqueConstraint check intact.

In `@backend/tests/test_api_schema_models.py`:
- Around line 25-33: FakeWriteSession에 비동기 get 모킹을 추가하고,
base_schema_snapshot_uuid를 전달해 _validate_base_snapshot 분기를 실행하는 API 테스트를 보강하십시오.
스냅샷이 없거나 다른 프로젝트에 속하거나 status가 "succeeded"가 아닌 각각의 경우에 대해 422 응답을 검증하고, 유효한 프로젝트
스냅샷 경로의 기존 동작은 유지하십시오.

In `@backend/tests/test_forward_migration_plan.py`:
- Around line 71-89: Rename the local variable target to base in
test_destructive_drop_has_explicit_risk_and_recovery_boundary, and pass base as
the first argument to compile_migration_plan while preserving the existing drop
assertions and behavior.

In `@backend/tests/test_forward_schema_model.py`:
- Line 139: Update the pytest.raises call around the primary_key validation
assertion to express its regex pattern as a raw string, preserving the existing
matching behavior and resolving Ruff RUF043.
- Around line 199-204: Update test_model_validation_fails_closed to annotate
mutate as Callable[[dict[str, Any]], object] and value as object wherever the
test’s variable arguments are declared. Also inspect setup.cfg’s mypy
configuration and ensure the intended backend/tests exclusion or coverage is
correctly applied.

In `@backend/tests/test_forward_snapshot_adapter.py`:
- Line 311: test_snapshot_adapter_fails_closed_for_uncompiled_features의 mutate
매개변수에 해당 테스트에서 사용하는 변이 함수의 정확한 타입을 지정하고, 기존 message 타입과 반환 타입은 유지하십시오. 인라인 람다나

In `@backend/tests/test_pg_introspect_connection.py`:

@seonghobae I reviewed exact head 94a110e2f3389c9eeab446ddf2f5ea4b0fcd7cbf.

I found no actionable source-level defect.

The delta adds the unwired stored-PostgreSQL live-preflight provider.

  • make_stored_postgres_live_preflight_factory() first calls load_guarded_live_preflight_target().
  • The lookup binds the run, plan, project, connection, succeeded base snapshot, state version, cancellation state, active attempt lease, digest, and expiry in one metadata query.
  • The provider decrypts only the returned ciphertext and nonce.
  • The provider opens the target through connect_guarded_postgres().
  • The provider does not accept SQL and has no apply path.

The snapshot binding is correct.

  • capture_exact_connection() rejects every connection object except the acquired target connection.
  • It forwards the validated stored schema_filter to capture_postgres_snapshot().
  • execute_bound_live_preflight() therefore receives a capture callback scoped to the same connection that executes the bounded preflight reads.

The cleanup and failure boundaries are correct.

  • The provider closes an acquired connection after normal completion, failure, and cancellation.
  • Decryption and connection failures map to MigrationDryRunWorkerError("migration live-preflight provider failed").
  • The provider suppresses exception details with from None.
  • asyncio.CancelledError, KeyboardInterrupt, and SystemExit propagate.

The focused tests cover:

  • guarded lookup before decryption and connection;
  • same-connection capture enforcement;
  • schema_filter propagation;
  • decryption and connection-error redaction; and
  • cancellation plus target-connection cleanup.

connect_guarded_postgres() is a public rename of the existing guarded connector. Existing probe, legacy apply, and introspection paths now use that function. The behavior remains the same.

The provider remains unwired. It does not remove the metadata-observation-to-target-opening gap. The documentation keeps deployed credential and network isolation, startup wiring, provider-backed PostgreSQL acceptance, worker operation, and all apply authority as release-blocking Planned work.

git diff --check passed.

Exact-head backend, frontend, PostgreSQL 14–18, Valkey, CodeQL, Semgrep, and security workflows were queued during inspection. Exact-head CI and security verification remain incomplete. The unresolved CodeRabbit thread is historical.

@seonghobae I reviewed exact head 6a78f1e0d33bdd178ec33ede07a2c1417b8bc7bc.

I found no actionable source-level defect.

The exact delta changes two files:

  • backend/app/jobs/live_preflight_provider.py
  • backend/tests/test_live_preflight_provider.py

The metadata-context failure path is now redacted.

  • The provider previously re-raised MigrationDryRunWorkerError.
  • A metadata session context manager could raise that error from __aexit__.
  • That error could contain sensitive metadata-driver detail.
  • The provider now catches every non-control exception from metadata lookup, metadata-context cleanup, decryption, and target connection acquisition.
  • It raises only MigrationDryRunWorkerError("migration live-preflight provider failed") with from None.

The new regression covers the required case.

  • test_provider_sanitizes_metadata_context_failures() makes session_context.__aexit__ raise a secret-bearing MigrationDryRunWorkerError.
  • The provider returns only the fixed provider error.
  • The resulting error text does not contain "secret".
  • decrypt_text() is not called after the metadata-context failure.

Control-flow behavior remains correct.

  • asyncio.CancelledError, KeyboardInterrupt, and SystemExit still propagate.
  • Existing cleanup behavior remains unchanged.
  • The exact delta adds no SQL, apply, dispatch, startup, or authorization behavior.

git diff --check passed.

Exact-head backend, frontend, PostgreSQL 14–18, Valkey, CodeQL, Semgrep, and security checks were queued during inspection. Exact-head CI verification remains incomplete.

The only unresolved review thread is a historical predecessor finding on docs/contracts/durable-dry-run-worker-v1.md.

Please review exact head c525f0c07c8ffb726e0781134f399f75ba1f611c, focusing on the PostgreSQL 14–18 stored-target provider composition, encrypted metadata/decryption lifecycle, same-connection capture, test-only loopback connector boundary, secret-safe failure behavior, and documentation maturity claims.

@seonghobae I reviewed exact head c525f0c07c8ffb726e0781134f399f75ba1f611c.

I found one actionable defect. It blocks review of the requested feature.

P1: Exact-head PostgreSQL 14–18 integration acceptance fails

All five PostgreSQL matrix jobs fail identically on this exact head:

  • PostgreSQL 14 + Valkey dual-lease acceptance — FAILURE
  • PostgreSQL 15 + Valkey dual-lease acceptance — FAILURE
  • PostgreSQL 16 + Valkey dual-lease acceptance — FAILURE
  • PostgreSQL 17 + Valkey dual-lease acceptance — FAILURE
  • PostgreSQL 18 + Valkey dual-lease acceptance — FAILURE

The backend, frontend, and Valkey 8 queue signal boundary jobs pass. Only the PostgreSQL integration matrix fails.

The failure is in test_real_postgres_durable_worker_recovers_without_sandbox_replay in backend/tests/test_postgres_migration_run_integration.py:

FAILED tests/test_postgres_migration_run_integration.py::test_real_postgres_durable_worker_recovers_without_sandbox_replay
Failed: durable sandbox stage failed after fixed evidence [...]: live preflight stage failed

This test is the exact scenario you asked me to focus on: the PostgreSQL 14–18 composition of the concrete stored-target provider through the test-only loopback connector.

Two facts from the log matter for triage:

  1. The test expects asyncio.CancelledError from the first (interrupted) attempt. Instead it received MigrationDryRunWorkerError("live preflight stage failed").
  2. The recorded sandbox stage evidence shows the sandbox completed cleanly (capture-completed twice for the pre-DDL and post-DDL convergence checks, then execution-completed and cleanup-completed). The failure therefore occurs after the sandbox stage, inside the live-preflight capability — most likely in the guarded-target lookup or in the new provider-composition assertions (dsn_ciphertext, dsn_nonce, base_schema_snapshot_uuid, schema_filter) that gate the raise asyncio.CancelledError for attempt 1.

Note also that the test's own failure message is mislabeled: pytest.fail(...) always prints "durable sandbox stage failed..." regardless of which stage actually failed. This masks the true failing stage and should be corrected together with the underlying defect so future failures are diagnosable from the message alone.

Because this failure reproduces identically on all five PostgreSQL majors, it is deterministic, not environmental flakiness. I cannot confirm review of same-connection capture, decryption lifecycle, or the loopback-connector boundary until this test passes on the exact head, since the failing assertion sits directly in that code path.

Please fix the failing assertion or exception-wrapping behavior, confirm the test passes on PostgreSQL 14–18, and re-request review at the new exact head.

git diff --check passed on the reviewed diff. Documentation maturity claims (Planned vs. Partially implemented labels in TRD, PRD, TEST_STRATEGY, UML, ADR-0002, and the durable-dry-run-worker-v1 contract) read as internally consistent with the intended provider-composition scope, but I withhold final sign-off on that documentation until the underlying test evidence it cites actually passes.

@coderabbitai review

Please review corrected exact head d63e457082f3701587f219c19e06076b5d4dfbc7. The predecessor matrix used a quoted sandbox schema name where the persisted API contract requires an unquoted schema filter; all PostgreSQL 14–18 cells failed closed before credential release. This head separates a valid target filter without weakening production validation or the DNS/SSRF guard. Treat predecessor checks and review as historical.

@seonghobae I reviewed exact head d63e457082f3701587f219c19e06076b5d4dfbc7.

I found no actionable source-level defect.

The exact delta changes one test file:

  • backend/tests/test_postgres_migration_run_integration.py

The correction separates two different test identities.

  • schema_name remains the quoted mixed-case sandbox schema name.
  • preflight_schema_filter is now a separate unquoted identifier: worker_preflight_<uuid>.
  • The test persists preflight_schema_filter in SchemaSnapshot.schema_filter.
  • The test asserts that the guarded lookup returns the same filter.

This matches the persisted schema-filter contract.

  • _SCHEMA_FILTER_RE remains [A-Za-z_][A-Za-z0-9_$]{0,62}.
  • load_guarded_live_preflight_target() still rejects an invalid stored filter with MigrationDryRunWorkerError("migration live-preflight target is invalid").
  • The change does not alter backend/app production code.

The DNS/SSRF boundary is unchanged.

  • The test-only loopback connector remains explicitly monkeypatched in the integration test.
  • It verifies the decrypted DSN by digest before opening the CI-local connection.
  • connect_guarded_postgres() remains unchanged.
  • It still calls validate_postgres_dsn_target() before asyncpg.connect().
  • The production DNS/SSRF/TLS guard remains active outside this test seam.

The current guarded handoff also includes the expected state version.

  • LivePreflightRequest includes expected_state_version.
  • The canonical lookup requires that exact state version.
  • The lookup also requires an active unexpired attempt and cancellation_requested is False.

git diff --check passed.

During inspection, PostgreSQL 15, Valkey, Python CodeQL, OSV, and Semgrep OSS checks had passed. PostgreSQL 14, 16–18, backend, frontend, and several security workflows were still queued or in progress. Exact-head CI verification is therefore incomplete.

One unresolved CodeRabbit thread remains on docs/contracts/durable-dry-run-worker-v1.md. It is a predecessor finding and is not introduced by this exact delta.

Please submit a fresh formal independent review for unchanged exact head d63e457082f3701587f219c19e06076b5d4dfbc7 against protected base 183331e1054fb14b4c017e77fcd0aae99e949277. Exact-head ci, Security Scan, and SAST Semgrep now pass, including PostgreSQL 14–18 provider-composed acceptance; CodeRabbit reported no actionable source-level defect. Do not transfer predecessor-head evidence. Please preserve the intentionally unresolved provider-deployment thread: application startup/consumer operation, concrete isolated sandbox lifecycle, deployed credential/network/process isolation, and live apply remain Planned.

Please review exact head 420593cfcd8f98efdbddf5c72536e16b01466a91, focusing on the post-connect exact guarded-target revalidation, connection cleanup before any target read on changed metadata, cancellation/error redaction, and the documented residual race after the second check. This head adds no startup wiring, sandbox provider, SQL, or apply authority.

@seonghobae I reviewed exact head 420593cfcd8f98efdbddf5c72536e16b01466a91.

I found no actionable source-level defect.

The provider now revalidates the exact guarded target after target connection acquisition.

  • make_stored_postgres_live_preflight_factory() performs the initial exact metadata lookup.
  • It decrypts only the returned guarded ciphertext and nonce.
  • It opens the target through connect_guarded_postgres().
  • It then performs the second exact metadata lookup.
  • It compares the second GuardedLivePreflightTarget with the first result.
  • It yields LivePreflightExecution only when both results are identical.

The mismatch path closes the connection before target reads.

  • The second lookup runs before yield.
  • A changed lookup result raises the fixed provider error.
  • The finally block closes the acquired connection.
  • test_provider_revalidates_exact_target_after_connection_open() verifies two lookups, zero snapshot-capture calls, the fixed error, and exactly one connection.close() call.

The error and cancellation boundaries remain correct.

  • Acquisition and revalidation failures return only MigrationDryRunWorkerError("migration live-preflight provider failed").
  • The code uses from None for non-control failures.
  • asyncio.CancelledError, KeyboardInterrupt, and SystemExit propagate.
  • The cancellation regression verifies target-connection cleanup after cancellation.

The documentation matches the implementation boundary.

  • It describes the post-connect revalidation before target reads.
  • It states that a metadata change after the second lookup remains possible.
  • It retains exact attempt leasing and fresh worker-state checks as required controls.
  • It keeps startup wiring, deployed sandbox lifecycle, deployed credential and network isolation, worker operation, SQL execution, and apply authority as Planned.

git diff --check passed.

Exact-head CI and security verification remain incomplete. Backend, frontend, PostgreSQL 14–18, Valkey, CodeQL, Semgrep, and Security Scan workflows were queued or in progress during inspection.

Please review exact head 745d4ec64b70dea28592765bd08f9b75daabe9ae, focusing on the new make_stored_postgres_durable_dry_run_attempt_handler same-session-factory authority binding, divergent-factory fail-closed path before I/O, timeout/config passthrough, and PostgreSQL 14–18 matrix entry through that composition. The predecessor-crash wrapper and private-CI loopback connector are test-only seams. This head adds no startup registration, sandbox provisioning, SQL input, or apply authority.

@seonghobae I reviewed exact head 745d4ec64b70dea28592765bd08f9b75daabe9ae.

I found no actionable source-level defect.

make_stored_postgres_durable_dry_run_attempt_handler has the requested authority binding.

  • It creates make_stored_postgres_live_preflight_factory(session_factory) with the captured SessionFactory.
  • It creates make_durable_dry_run_attempt_handler(...) with that provider.
  • Its returned handler requires attempt_session_factory is session_factory.
  • If the consumer supplies a different factory, it raises MigrationDryRunWorkerError("migration dry-run composition is invalid").
  • The check occurs before it awaits the durable handler. It therefore occurs before the durable handler can perform metadata or target I/O.

The configuration passthrough is complete.

  • The composition forwards lock_timeout_ms.
  • It forwards both statement timeouts.
  • It forwards both whole-stage timeout values.
  • The unit test verifies defaults and a non-default preflight_stage_timeout_seconds.

The test coverage matches the new composition boundary.

  • test_composition_binds_one_metadata_factory_to_provider_and_attempt() verifies the exact provider factory input.
  • It verifies durable-handler arguments.
  • It verifies valid delegation with the captured factory.
  • It verifies a divergent factory fails with the fixed composition error.
  • The failed call does not await the delegate.

The PostgreSQL 14–18 recovery acceptance now enters through make_stored_postgres_durable_dry_run_attempt_handler.

  • The test uses the same sessions factory for composition and handler invocation.
  • The predecessor-crash wrapper remains a test seam.
  • The successor path uses the concrete provider created before the wrapper is installed.
  • The private-CI loopback connector remains explicitly test-only.
  • The test still verifies no sandbox replay after the interrupted predecessor attempt.

The documentation preserves the maturity boundary.

  • Startup registration remains Planned.
  • Sandbox lifecycle remains injected.
  • The loopback connector and predecessor-crash wrapper are test-only.
  • The slice adds no SQL input path or apply authority.

git diff --check passed. The unresolved-thread query returned no unresolved threads.

All exact-head CI and security checks were queued during inspection. Exact-head CI verification remains incomplete.

Strix exact-head failure RCA for 745d4ec64b70dea28592765bd08f9b75daabe9ae (run 31834064971):

  • The organization workflow could not compute a merge base and explicitly materialized only 55 changed files into /tmp/strix-pr-scope.*.
  • Its sole HIGH report says backend/app/pg_introspect/dsn_guard.py was missing, then describes creating it inside that scan sandbox. The report therefore evaluated an incomplete changed-file sandbox as though it were the repository tree.
  • The unchanged exact PR tree already contains that file as blob 9df07e002c9c181598e0c7c40b149d612e515971; it is byte-identical to protected base and is intentionally absent from the PR changed-file list.
  • Exact-tree application imports succeed for both app.pg_introspect.dsn_guard.validate_postgres_dsn_target and app.db_introspect.validate_database_dsn_target.
  • Focused exact-tree verification is green: 61 passed across tests/test_dsn_guard.py and tests/test_db_introspect.py. Repository Security Scan and SAST Semgrep also pass on this exact head.

Verdict: this Strix finding is a non-actionable false positive caused by the central workflow's partial changed-file materialization, not a missing module or SSRF regression in PR #834. I am not touching dsn_guard.py merely to force it into scan scope; that would be a symptom workaround and would invalidate exact-head evidence. The central Strix workflow owns the root-cause remedy: scan the complete exact-head tree (or otherwise include transitive unchanged dependencies) before interpreting import failures.

No merge is attempted while the failed organization security run remains unresolved.

Exact-head review request for 7bc25d75dfe14d733fc970314d81a8c4febfb4de.

@coderabbitai review
@opencode-agent review

This test-first slice adds only make_stored_postgres_migration_run_handler: it composes the existing same-session stored PostgreSQL dry-run attempt capability with exact worker-attempt lease/heartbeat ownership. The RED predecessor a3ed0a9ac3e3046134512545e338cfbd93d2502a failed backend pytest collection with exit code 2 because the entry point was absent. On this head, repository CI, Security Scan, SAST Semgrep, frontend/backend, Valkey, and PostgreSQL 14–18 dual-lease jobs all pass.

Please review the exact head for authority expansion, session-factory identity preservation, lease parameter forwarding, fixed non-secret failure behavior, and documentation accuracy. Startup registration, concrete sandbox deployment, target apply, and production-readiness claims remain explicitly out of scope. A qualifying non-author formal approval is still required.

@seonghobae I reviewed exact head 7bc25d75dfe14d733fc970314d81a8c4febfb4de.

I found no actionable source-level defect.

  • The immediate delta contains only the new composition, its contract update, and the changelog entry.
  • make_stored_postgres_migration_run_handler() preserves the captured SessionFactory.
  • It creates make_stored_postgres_durable_dry_run_attempt_handler() with that factory and the injected sandbox factory.
  • It forwards all four dry-run timeout settings unchanged.
  • It passes worker_identity, attempt_lease_seconds, and heartbeat_interval_s to make_attempt_bound_migration_run_handler().

The authority boundary remains correct.

  • The composition performs no I/O.
  • The composition does not decrypt credentials.
  • The composition does not open a target connection.
  • The composition does not start a consumer.
  • The composition does not provision or register a sandbox.
  • The composition accepts no SQL and grants no apply authority.

The existing durable-attempt composition rejects a divergent session factory before it calls the durable handler. The outer lease wrapper validates the attempt lease and heartbeat interval. It also converts handler failures to fixed non-secret errors before consumer retry handling.

backend/tests/test_live_preflight_provider.py::test_consumer_composition_binds_attempt_leases_to_stored_provider() verifies:

  • exact SessionFactory forwarding;
  • sandbox factory forwarding;
  • timeout forwarding;
  • worker identity forwarding;
  • attempt-lease forwarding; and
  • heartbeat forwarding.

The PostgreSQL 14–18 acceptance remains intentionally scoped to make_stored_postgres_durable_dry_run_attempt_handler(). The contract states this scope. It does not claim that the matrix enters through the new migration-run handler.

The documentation accurately retains the Partial maturity boundary. Application startup registration, concrete sandbox deployment, deployed credential and network isolation, worker operation, and live apply remain Planned.

git diff --check passed. Exact-head backend, frontend, Valkey, PostgreSQL 14–18, CodeQL, Semgrep, and Security Scan component checks were successful during inspection. The strix check was still in progress.

Inline comments:
In `@backend/tests/test_durable_dry_run_worker_documentation.py`:
- Line 56: Retain the EN DASH in the “PostgreSQL 14–18 matrix stores” string and
add a narrowly scoped Ruff RUF001 suppression for that line, without changing
the assertion text.

In `@backend/tests/test_request_validation.py`:
- Line 49: Rename the local secret variables at the referenced test locations
from secret to sensitive_marker (or another non-secret name) while preserving
their existing values and test assertions, so Ruff S105 is no longer triggered.

Apply the same fix in `@backend/tests/test_api_dbml.py` around lines 25 - 26: 동일한
테스트 표식 변수명으로 Ruff S105가 발생합니다.

In `@docs/doctoring/dbml-identifier-ddl-boundary.md`:
- Around line 43-51: Update the seven test-evidence references to use
repository-root-relative backend/tests/... paths: change all four tests/...
references in docs/doctoring/dbml-identifier-ddl-boundary.md lines 43-51 and all
three tests/... references in docs/doctoring/multiline-sql-request-controls.md
lines 36-45. No code changes are needed.

In `@docs/UML.md`:
- Around line 63-81: Update the UML documentation’s status descriptions to
remove worker/attempt binding from the Planned components list, since
consumer-to-attempt binding is implemented; retain deployed worker execution and
application startup wiring as Planned items.

---

Outside diff comments:
In `@backend/tests/test_postgres_migration_run_integration.py`:
- Around line 1000-1002: Update make_crash_injected_provider to annotate
actual_sessions with the existing SessionFactory type alias and annotate its
return value with LivePreflightFactory, preserving the current assertion and
live_factory return behavior.

---

Nitpick comments:
In `@backend/app/jobs/live_preflight_provider.py`:
- Line 42: Update make_stored_postgres_live_preflight_factory to accept a
keyword-only connection timeout parameter, defaulting to
_CONNECT_TIMEOUT_SECONDS, and use it wherever the connection acquisition timeout
is configured. Preserve the existing default behavior while allowing callers to
override the timeout.

In `@backend/app/spec/dbml_import.py`:
- Around line 188-206: Update _split_col_ref to parse reference paths through
_consume_identifier_path with maximum_segments=3, reusing its quote handling and
identifier decoding instead of _PATH_SEGMENT_RE. Preserve the existing
schema/table/column defaults and too-many-segments error behavior.

In `@docs/adr/ADR-0002-isolated-dry-run-and-preflight.md`:
- Around line 15-25: Add relevant academic literature supporting the ADR’s
claims about production DDL rollback risks and the dual-evidence model,
including full citations and permissible paper links or PDFs plus brief
summaries of how each source applies. Place this material in the ADR or PR
