…n bypass fix [TDD-RED] Encodes post-fix contract from Taura Security pentest finding (28/04/2026): actor_mapping identity fields become append-only; pseudonymization is irreversible per actor_id; mutation attempts surface as HTTP 409 via a new ErrActorMappingImmutable sentinel. Failing tests cover: - Service: CreateOrGetActorMapping (renamed from UpsertActorMapping) for AC1 (new actor), AC2 (idempotent no-op), AC3/AC4 (different email/name), AC5 (pentest PoC: PUT over [REDACTED]). - Repository sqlmock: INSERT ... ON CONFLICT DO NOTHING RETURNING contract, post-INSERT SELECT comparison path, ErrActorMappingImmutable on divergence. - HTTP handler: PUT mapped to 200 (create / idempotent) or 409 (mutation / redacted overwrite attempt). Build is intentionally RED until Gate 0.2 (TDD-GREEN) introduces: - command.ErrActorMappingImmutable - ActorMappingUseCase.CreateOrGetActorMapping - actormapping.ErrActorMappingImmutable - INSERT ... ON CONFLICT DO NOTHING SQL + compare-or-fail logic - Handler error-to-409 mapping
…eation [TDD-GREEN] Addresses Taura Security pentest finding (28/04/2026): pseudonymization of actor mappings could be silently reverted via subsequent PUT requests. The fix introduces: - ErrActorMappingImmutable sentinel in domain/errors, re-exported by the adapter and service layers so errors.Is works across the layer boundary without violating depguard service-no-adapters - INSERT ... ON CONFLICT DO NOTHING + transaction-scoped SELECT compare at the SQL layer, replacing the COALESCE-based upsert that allowed plaintext PII to overwrite [REDACTED] values; the same-transaction compare closes the TOCTOU window - CreateOrGetActorMapping service method documenting the new append-only semantics; UpsertActorMapping kept as a thin wrapper for the existing HTTP handler - 409 Conflict response on PUT attempts that mutate display_name or email, surfaced via the slug governance_actor_mapping_immutable - Idempotent no-op for PUT with identical payload (HTTP PUT semantics preserved, updated_at unchanged) - Swagger documentation of the 409 response Defense-in-depth: validation enforced at both service and SQL layers. Identity-mutation failures use HandleSpanBusinessErrorEvent so they don't inflate 5xx dashboards. The previous test TestUpsert_PreservesExistingFieldsWhenInputIsNil exercised the vulnerable COALESCE behavior; it is replaced by TestUpsert_PartialPayloadRejectedWhenStoredFieldsDiffer covering the new contract.
…iants Adds three property-based fuzz targets covering the helpers that gate the pseudonymization-bypass fix (Taura Security pentest, 28/04/2026): - FuzzStringPtrEqual asserts reflexivity, symmetry, and the documented nil/empty/byte-equality semantics. Any drift here would silently allow a mutation through the conflict path of insertOrCompare. - FuzzActorMappingPIIDiffers asserts reflexivity, symmetry, and the nil-arg "differs" contract — the invariants the immutability check depends on. - FuzzNewActorMapping asserts the XOR(success, error) contract of the constructor and validates the trimming/length sentinels never panic under adversarial UTF-8, NUL bytes, or overlong inputs. Each target ran for 10s with no findings (10 seed inputs total, ~2.5M executions combined).
…nvariants Gate 5 of fix-actor-mapping-pseudonymization-bypass. Encodes domain invariants from the Taura Security pentest finding (28/04/2026) as testing/quick property checks (MaxCount=1000 per property). Properties: - IsRedacted is well-defined (biconditional vs hand-coded reference), partial-redaction always false, nil receiver returns false. - Pseudonymization is irreversible — after a row enters [REDACTED], no Upsert/CreateOrGetActorMapping puts plaintext PII back on disk until DELETE clears the row. - CreateOrGetActorMapping is idempotent for identical args. - Mutation of display_name OR email on an existing row returns ErrActorMappingImmutable and leaves the stored row untouched. Uses a hand-rolled statefulFakeRepository that mirrors the post-fix INSERT...ON CONFLICT DO NOTHING + SELECT + compare semantics from the postgres adapter, driven by a deterministic LCG-decoded trace generator.

…y and TOCTOU resistance Gate 6 WRITE phase for fix-actor-mapping-pseudonymization-bypass. Adds 9 testcontainers-backed integration tests in the actor_mapping adapter package covering the post-fix INSERT ... ON CONFLICT DO NOTHING + SELECT compare contract end-to-end against real PostgreSQL: AC1 NewActor_PersistsAndReturnsEntity AC2 IdempotentSameValues_NoMutation (verifies updated_at pinned) AC3/4 DifferentPayload_ReturnsImmutable (row preserved) AC5 OverRedacted_ReturnsImmutable (plaintext-over-redacted PoC) AC5 OverRedacted_ConcurrentPlaintextAttacks_AllFail (race PoC) AC7 DeleteAfterPseudonymize_Succeeds AC8 ConcurrentDifferentPayloads_NoMutation (load-bearing race) AC8 ConcurrentIdenticalPayloads_AllSucceedIdempotently AC8 ConcurrentFreshActor_OneInsertsRestSeeWinner (TOCTOU on fresh ID) Tests use the shared tests/integration.TestHarness which spins Postgres 17 + Valkey 8 + RabbitMQ via testcontainers, runs the embedded migrations, and provides a tenant-scoped InfrastructureProvider. Tests authored only; orchestrator will execute at cycle-end.
…contract Two pre-existing tests in tests/integration/governance/actor_mapping_test.go encoded the PRE-FIX vulnerable behaviour of the actor_mapping upsert path (COALESCE-based UPDATE on conflict) and would fail under the new immutability contract introduced to close the pseudonymization-bypass finding. - Removed TestIntegration_Governance_ActorMapping_UpsertUpdatesExisting: redundant with TestIntegration_ActorMappingImmutability_DifferentPayload_ReturnsImmutable in internal/governance/adapters/postgres/actor_mapping/actor_mapping_immutability_integration_test.go, which already pins "existing row + different payload → ErrActorMappingImmutable + row unchanged" end-to-end. - Reframed TestIntegration_Governance_ActorMapping_UpsertPreservesExistingFieldWhenOmitted into TestIntegration_Governance_ActorMapping_UpsertPartialPayloadIsRejected: the new path has no COALESCE escape hatch, so a partial PUT (different display_name, nil email) against an existing row must surface ErrActorMappingImmutable and leave the persisted row untouched. This documents the no-COALESCE contract from the package-level integration harness. Pure test-side adjustment; no production code touched.
…r DB failure injection
Authors five Toxiproxy-driven chaos scenarios under build tag `chaos` to
verify the post-fix Upsert path (INSERT ON CONFLICT DO NOTHING + in-tx
SELECT-compare) keeps its immutability guarantee when Postgres misbehaves:
1. Connection drop mid-transaction against an existing row → caller
errors out, row UNCHANGED.
2. Connection drop / cancellation around a fresh-actor INSERT → either
the full payload landed or the row is absent; never partial.
3. Pseudonymized [REDACTED] row + 1s latency + concurrent plaintext
attackers → zero successes, row remains [REDACTED]/[REDACTED].
4. PG proxy fully disabled → repo returns a wrapped error, no panic,
no nil-without-error, no hang (10s watchdog).
5. Disable / re-enable proxy → idempotent re-PUT recovers, persisted
row matches the submitted payload exactly.
Tests WRITE-only at this gate; execution is deferred to cycle-end per
gate cadence. Reuses tests/chaos harness (ChaosHarness, InjectPGResetPeer,
InjectPGLatency, DisablePGProxy, DirectDB) — no new infrastructure.
The actor_mapping immutable handler was using LogSpanError for the 409 Conflict path, which calls libOpentelemetry.HandleSpanError and marks the span as failed. A 409 raised by the post-fix immutability contract is a client-side mistake (the persisted row is untouched), not an infrastructure or server fault — it MUST not pollute the error budget. Adds sharedhttp.LogSpanBusinessEvent which records the event via libOpentelemetry.HandleSpanBusinessErrorEvent (no error attribution) and still emits the SafeError log line. Switches writeConflict to use it and updates the docstring to match. Refs Gate 8 review finding H-1.
Adds CodeGovernanceActorMappingImmutable = "MTCH-0604" to the product error code table and wires the governance_actor_mapping_immutable slug into the shared HTTP error catalog so 409 responses from the actor mapping immutability path surface the stable product code instead of the generic conflict fallback. Clients can now branch on MTCH-0604 to distinguish the pseudonymization-bypass rejection from other conflict modes. Refs Gate 8 review finding M-1.
H-2: The sqlmock regex helpers used .* between SQL tokens, which would silently accept arbitrary SQL injected between, say, DO NOTHING and RETURNING. Replaces .* with \s+ where the gap is whitespace, and bounds the column-list and VALUES segments with [^)]* so injection inside parentheses is also rejected. Removes the dead `regexp` import that only existed to satisfy a `var _ = regexp.MustCompile` compile-time guard. M-2: The three immutability handler tests asserted only the HTTP status code, not the response body. Decodes the JSON body and verifies the product code equals constant.CodeGovernanceActorMappingImmutable (MTCH-0604) and the message describes the immutability constraint. This closes the loophole where the handler could return 409 with a generic "conflict" payload and the test would still pass. Also drops the dead `var _ = http.StatusOK` compile-time guard from the handler test file and updates the file-header comment to "Pins post-fix contract" (the GREEN phase has shipped — the TDD-RED header is stale). Pretty-prints the fuzz seed corpus via gofmt (no behavior change). Refs Gate 8 review findings H-2, M-2, L1, L2.
The pseudonymization-irreversibility property tracked `redacted` by consulting `snap.IsRedacted()` after every operation, which collapsed the invariant into a tautology: the model state was derived from the repository state, so the assertion `if redacted: require snap.IsRedacted()` was always trivially true. Reworks the state oracle so `redacted` is set ONLY by opPseudonymize on an existing row and cleared ONLY by opDelete or the delete step of opRecreate. The repository snapshot is now used exclusively for invariant assertions, never to derive the oracle's flag. The property now genuinely fails if a future regression allows an Upsert/Create call to overwrite a [REDACTED] row. Refs Gate 8 review finding H-3.
…e bucket floor H-4: The five actor_mapping chaos tests called truncateActorMappingDirect without acquiring the shared chaos harness mutex (h.testMu). If the chaos suite is ever run with t.Parallel enabled, the tests would cross- contaminate each other's Toxiproxy injections and direct-DB state. Exposes a new ChaosHarness.LockTest(t) helper that acquires h.testMu and registers t.Cleanup to release. The five actor_mapping chaos tests now call h.LockTest(t) at the top so they are mutually exclusive with each other (and with ResetDatabase-using tests) regardless of -parallel. H-5: PseudonymizedRowUnderLatency_StillRejectsAttacker tolerated runs where 100% of attacker calls fell into the timeout/otherErrors buckets, masking a real bypass behind a degenerate environment. Adds a require.GreaterOrEqual(immutableHits, 1) assertion so at least one attacker MUST observe ErrActorMappingImmutable for the scenario to count as a valid pass. Refs Gate 8 review findings H-4, H-5.
The previous TestActorMapping_Update PUT-ed an existing actor_id with a
different display_name and asserted the row was updated — that
asserted the pre-fix mutation behavior, which the post-fix contract now
rejects with 409.
Replaces the test with two scenarios that pin the new contract:
* TestActorMapping_IdempotentSamePayload — second PUT with identical
display_name/email returns 200 and echoes the same row.
* TestActorMapping_MutationReturnsConflict — second PUT with a
different display_name returns 409 with the
governance_actor_mapping_immutable product code (MTCH-0604); the
persisted row is unchanged.
Uses the existing client.APIError.IsConflict / ProductCode helpers; no
changes to tests/client/governance.go are required.
Refs Gate 8 review finding C-1.
…mutability M-3: The ActorMappingRepository interface doc still described Upsert as "creates or updates an actor mapping" — that wording matches the pre-fix mutable contract. Updates both the type-level and Upsert-level doc comments to reflect the post-fix append-only contract: identity fields cannot be mutated in place; mismatching payloads return ErrActorMappingImmutable; pseudonymization and right-to-erasure remain the only state transitions. M-4: Migration 000001 still carries the original COMMENT ON TABLE text claiming the table is "Mutable". Adds migration 000033 to update the COMMENT to describe the append-only contract and the governance_actor_mapping_immutable (MTCH-0604) rejection. Migration 000001 itself is left untouched per the standard rule against editing applied migrations. The .down.sql restores the pre-fix COMMENT text. Refs Gate 8 review findings M-3, M-4.
M-1: remove dead actorID empty-string reject branch in actor_mapping_immutability_property_test idempotency test. actorID is built from a uint16 seed so it can never be empty; the guard was dead code flagged by ring:test-reviewer. M-2: collapse dead conditional in the irreversibility oracle's opCreate/opRecreate arm. Both branches of "if ok && !redacted else if ok" performed the same assignment; rewrite as a single "if ok" with explicit comment about redacted-flag ownership (set by opPseudonymize, cleared by opDelete/opRecreate-delete) to keep the oracle independent of repo state per commit 9a2dd57. M-3: update ActorMapping entity docstring to reflect the post-fix append-only contract. Old text claimed the table was "mutable by design for GDPR compliance"; new text documents append-only identity fields, the ErrActorMappingImmutable / MTCH-0604 / HTTP 409 rejection, and the two allowed state transitions (Pseudonymize and DELETE), with a pointer to migration 000033. M-4 (skipped): CHANGELOG entry was not added manually because the repo uses semantic-release with @semantic-release/changelog plugin; manual edits would be overwritten. The release-engineering gap (no BREAKING CHANGE: footer in any branch commit, so semver may emit only a patch bump for a public-API breaking change) is surfaced for the release owner as a follow-up; it is out of Gate 8 cleanup scope.

Applies all 7 findings from the local CodeRabbit review against the fix-actor-mapping-pseudonymization-bypass branch before opening PR. Grupo A — Swagger field name (3 findings, 1 root cause): - handlers_actor_mapping.go: replace display_name with displayName in the Swagger @description and doc comment for UpsertActorMapping. The request JSON field is camelCase per the DTO, so the snake_case description would have misled SDK consumers. - Regenerated docs/swagger/{docs.go, swagger.json, swagger.yaml} via make generate-docs. Grupo B — Test improvements (3 findings): - actor_mapping_immutability_fuzz_test.go: replace uuid.NewString() with a fixed UUID constant fuzzFixedActorID. Random UUIDs per fuzz iteration violate the project rule of deterministic test data and would make any fuzz failure non-reproducible. - actor_mapping_chaos_test.go:482-484: assert.Error/assert.Nil → require.Error/require.Nil for the graceful-degradation contract (Upsert with PG unreachable MUST return an error, and MUST NOT also return a non-nil entity). Subsequent assertions should not run if this invariant is violated. - actor_mapping_chaos_test.go:393: assert.Equal → require.Equal for the zero-plaintext-overwrite security invariant under chaos latency injection. This is the load-bearing assertion for the entire pseudonymization-bypass fix; subsequent assertions should fail-fast. Grupo C — Chaos harness API hygiene (1 nitpick): - tests/chaos/harness.go: rename ChaosHarness.LockTest → LockHarnessForTest for clarity (avoids "test the lock" misreading). - tests/chaos/common.go: add atomic.Bool testLockHeld field on ChaosHarness. Both LockHarnessForTest and ResetDatabase now CompareAndSwap before acquiring testMu, failing fast via t.Fatalf if the harness is already locked by the same test (instead of deadlocking on double-acquire). All 5 callers in actor_mapping_chaos_test.go updated to the new name. Verification: - go vet ./... clean (including chaos build tag) - go test -tags=unit ./internal/governance/... all green - go test -tags=unit ./tests/... all green - grep display_name in docs/swagger/ → 0 results - grep LockTest in tests/chaos/ → 0 results - grep uuid.NewString in fuzz file → 0 results No production logic changed. Only Swagger doc text, test data sources, and assertion strictness. Refs CodeRabbit local review 2026-05-14, 7 findings, all resolved.
Addresses CodeRabbit re-review findings #5 and #6 by documenting the chaos test suite's intentional single-threaded model, rather than refactoring the testLockHeld CAS-before-mutex pattern. Background: commit 0e6e076 "test(chaos): serialize actor_mapping chaos tests..." established that the chaos suite runs with -p 1 (see Makefile target test-chaos). Under this model, LockHarnessForTest and ResetDatabase never run concurrently from different tests; the testLockHeld flag exists only to detect the same-test double-lock scenario (a test that mistakenly calls both helpers, which would deadlock on testMu). The current CAS-before-mutex pattern fails fast via t.Fatalf when the flag is already set, instead of blocking on the mutex. This is correct under serial execution and is now explicitly documented as deliberate. If the chaos suite is ever changed to permit concurrent test execution, the docstring flags that the CAS pattern must be revisited (the current pattern would incorrectly fail legitimate concurrent tests instead of serializing them through proper mutex contention). Changes: - tests/chaos/harness.go: append SERIAL-EXECUTION INVARIANT block to LockHarnessForTest docstring (full rationale + revisit-trigger note) and a shorter cross-reference paragraph to ResetDatabase docstring. - No code changes; testLockHeld CAS and testMu logic untouched. Findings #1, #2, #3, #4 deliberately deferred: - #1 (state metrics zeroed): metadata, not entrega - #2/#3 (task spec post-hoc edits): task spec is historical spec - #4 (reflectKindCheck): conscious decision from Gate 8 iter 1
Addresses CodeRabbit round-3 finding #1 (minor potential_issue) by appending the explicit error code MTCH-0604 to the @failure 409 annotation on UpsertActorMapping. The 409 response in swagger.json now reads "Actor mapping identity is immutable (MTCH-0604)", making the API contract self-documenting for consumers parsing only the OpenAPI spec (without needing to inspect ErrorResponse examples). Files: - handlers_actor_mapping.go: 1-line annotation update - docs/swagger/{docs.go,swagger.json,swagger.yaml}: regenerated via make generate-docs Other CodeRabbit round-3 findings deliberately skipped: - #2 (CRITICAL, fuzz build tag): CodeRabbit suggested changing //go:build unit → //go:build fuzz in actor_mapping_fuzz_test.go. This conflicts with the Matcher project's local convention: all 23 other fuzz_test.go files use //go:build unit (verified via grep) and there is no test-fuzz Makefile target. The suggestion comes from a generic Ring standard; local convention prevails. Changing the tag would break fuzz execution under `make test-unit` and create inconsistency with the rest of the codebase. - #3 (trivial, reflectKindCheck): repeated nitpick from Gate 8 iter 1 and round 2; conscious decision retained. - #4 (trivial, task spec isolation level clarification): task spec is a historical planning document; post-hoc edits skipped per consistent policy.

- Around line 57-68: This file fails the gci import ordering check; reformat
actor_mapping.go by running the gci tool to reorder and normalize imports (e.g.
run gci -w internal/governance/domain/entities/actor_mapping.go or your repo's
format/make target that runs gci), then run gofmt/goimports (or the project's
make format) to apply final formatting and commit the updated file so the linter
passes; ensure the file header comment and package/identifier names
(actor_mapping.go, package/entities) remain unchanged.
In `@internal/governance/services/command/actor_mapping_immutable_test.go`:
- Around line 64-66: Replace the gomock-based setup (gomock.NewController and
mocks.NewMockActorMappingRepository) with a small in-file manual stub that
implements the ActorMappingRepository interface: define a stub struct (e.g.,
stubActorMappingRepo) with function fields for the interface methods (at minimum
Upsert) and implement those methods to delegate to the function fields; update
tests in actor_mapping_immutable_test.go to instantiate this stub and set the
Upsert behavior inline instead of setting gomock expectations; ensure the stub
type name and method signatures exactly match ActorMappingRepository so it
satisfies the interface used by the test.
In `@tests/e2e/journeys/actor_mapping_test.go`:
- Around line 82-103: Add assertions to verify idempotency of timestamps: after
the first UpsertActorMapping call capture firstResp.CreatedAt and
firstResp.UpdatedAt (ensuring they are non-nil), then after the second
UpsertActorMapping (secondResp) assert secondResp.CreatedAt equals
firstResp.CreatedAt and secondResp.UpdatedAt equals firstResp.UpdatedAt; also
assert GetActorMapping (getResp) returns the same CreatedAt and UpdatedAt as
firstResp. Make sure to check for non-nil CreatedAt/UpdatedAt on firstResp,
secondResp, and getResp before comparing to avoid nil dereference.

CI lint failure on Go Analysis / Lint (matcher) job (run 25940398927) flagged the docstring at actor_mapping.go:63 as "File is not properly formatted (gci)". Root cause: the Immutability contract list items (a) UPDATE... / b) DELETE... used 7 spaces of indentation after the // prefix; golangci-lint's gci/gofumpt enforcement wants 5 spaces to align with the parent list bullet style. Reduced indentation from 7 spaces to 5 spaces on both bullets. No content change — only whitespace inside the comment block. Local make lint earlier in the cycle had stale cache; running make lint-fix now reproduces and corrects the issue. Verified make lint clean post-fix (0 issues).
Cherry-picks the change from open dependabot PR #140 to unblock the security scan CI on this PR. The 1.26.2-alpine base image carries 16 Go stdlib/runtime CVEs from the 2026 disclosure cycle: - CVE-2026-33811 (LookupCNAME cgo DNS DoS) - CVE-2026-33814 (HTTP/2 SETTINGS infinite loop) - CVE-2026-39820 (ParseAddress/ParseAddressList DoS) - CVE-2026-39836 (Dial/LookupPort NUL byte panic on Windows) - CVE-2026-42499 (consumePhrase DoS) - CVE-2026-39823/25/26 (URL parsing, ReverseProxy, html/template) All fixed in 1.26.3-alpine. Bump is byte-for-byte identical to PR #140 (automated dependabot upgrade); applied here because the security gate on PR #150 is otherwise blocking on these pre-existing CVEs that this PR did not introduce. If #140 merges into develop first, the resulting merge conflict on this PR will be trivial (same single-line change). Scope diluition is justified: the bump is the upstream-recommended fix for the exact CVEs blocking this PR's CI; combining them in one PR avoids a circular dependency where neither can merge without the other.

Applies CodeRabbit Cloud finding C (trivial nitpick, quick win) on PR #150. The TestActorMapping_IdempotentSamePayload e2e journey now also asserts that `CreatedAt` and `UpdatedAt` remain byte-identical between the first and second PUT responses, strengthening the no-op contract for AC2 (idempotent PUT with identical payload). Previously the test only verified that identity fields (displayName, email) round-tripped intact. Adding the timestamp assertions guards against a regression where the repository would touch updated_at on a no-op write — e.g. if the INSERT ... ON CONFLICT DO NOTHING path were ever changed to ON CONFLICT DO UPDATE with COALESCE again. The integration-tier check already pins this at second precision (actor_mapping_immutability_integration_test.go); this e2e assertion adds end-to-end timestamp stability through the full HTTP + API client stack. Other CodeRabbit Cloud findings deliberately deferred (see PR replies): - A (typed input struct for CreateOrGetActorMapping): inconsistent with sibling commands in the same file that use primitive params; would require broader cleanup PR - B (manual stub for ActorMappingRepository): MockActorMappingRepository is already generated by mockgen and used by sibling tests; refactor would create divergence - D (ErrActorMappingImmutable in entity file): sentinel already lives in domain/errors/errors.go parallel to ErrActorMappingNotFound, with type-aliases at service and adapter layers; adding a fourth declaration site duplicates without resolving

…arity Applies CodeRabbit Cloud follow-up nitpick on PR #150 (review at 2026-05-15T21:17:53Z). Extends the timestamp assertions in TestActorMapping_IdempotentSamePayload with: 1. Non-empty assertions on the first PUT response (createdAt, updatedAt) to guard against a false-positive where both responses happen to carry zero-valued timestamps. 2. GET response timestamp parity vs the first PUT response, asserting that GET preserves the same CreatedAt/UpdatedAt the row was inserted with — i.e., the read path does not synthesize new timestamps and the row was never silently rewritten between PUT and GET. Combined with the existing PUT-vs-PUT timestamp equality (commit 0441fe8), the e2e idempotency journey now pins the full chain: - First PUT returns non-zero timestamps - Second PUT echoes the same timestamps (no-op write contract) - GET returns those same timestamps (read path is faithful)

Superseded — finding C (timestamps) fixed in 0441fe8 + extension in 5f8de67 (CodeRabbit follow-up nitpick). Findings A, B, D deferred with documented justification in inline reply threads and PR-level comment. Latest CodeRabbit review (21:17:53Z) is state=COMMENTED, not CHANGES_REQUESTED. Dismissing this stale review to reflect current state.
Addresses CodeRabbit Cloud review 4301505026 — the "Arquivos afetados" section of the task spec listed paths/symbols speculated during planning that ended up diverging from the implementation: - ErrActorMappingImmutable moved from services/command/commands.go to domain/errors/errors.go (matches existing governance error pattern; re-exported via type-aliases at service and adapter layers) - IdentityEquals helper was not added to the entity; comparison logic lives in the adapter as actorMappingPIIDiffers / stringPtrEqual - New shared helpers (LogSpanBusinessEvent), constants (CodeGovernanceActorMappingImmutable), and error catalog entries (defGovernanceActorMappingImmutable) were not anticipated by the original task spec but materialized during implementation - Test file inventory now lists the actual filenames (*_immutable_test.go, *_immutability_*_test.go) instead of the original speculative names The task spec now serves as an accurate map of the implementation for future maintainers reading docs/tasks/.

Dismissing this CHANGES_REQUESTED review now that the documented finding is resolved.

Grupo A — Swagger field name (3 findings, 1 root cause): - handlers_actor_mapping.go: replace display_name with displayName in the Swagger @description and doc comment for UpsertActorMapping. The request JSON field is camelCase per the DTO, so the snake_case description would have misled SDK consumers. - Regenerated docs/swagger/{docs.go, swagger.json, swagger.yaml} via make generate-docs. Grupo B — Test improvements (3 findings): - actor_mapping_immutability_fuzz_test.go: replace uuid.NewString() with a fixed UUID constant fuzzFixedActorID. Random UUIDs per fuzz iteration violate the project rule of deterministic test data and would make any fuzz failure non-reproducible. - actor_mapping_chaos_test.go:482-484: assert.Error/assert.Nil → require.Error/require.Nil for the graceful-degradation contract (Upsert with PG unreachable MUST return an error, and MUST NOT also return a non-nil entity). Subsequent assertions should not run if this invariant is violated. - actor_mapping_chaos_test.go:393: assert.Equal → require.Equal for the zero-plaintext-overwrite security invariant under chaos latency injection. This is the load-bearing assertion for the entire pseudonymization-bypass fix; subsequent assertions should fail-fast. Grupo C — Chaos harness API hygiene (1 nitpick): - tests/chaos/harness.go: rename ChaosHarness.LockTest → LockHarnessForTest for clarity (avoids "test the lock" misreading). - tests/chaos/common.go: add atomic.Bool testLockHeld field on ChaosHarness. Both LockHarnessForTest and ResetDatabase now CompareAndSwap before acquiring testMu, failing fast via t.Fatalf if the harness is already locked by the same test (instead of deadlocking on double-acquire). All 5 callers in actor_mapping_chaos_test.go updated to the new name. Verification: - go vet ./... clean (including chaos build tag) - go test -tags=unit ./internal/governance/... all green - go test -tags=unit ./tests/... all green - grep display_name in docs/swagger/ → 0 results - grep LockTest in tests/chaos/ → 0 results - grep uuid.NewString in fuzz file → 0 results No production logic changed. Only Swagger doc text, test data sources, and assertion strictness. Refs CodeRabbit local review 2026-05-14, 7 findings, all resolved. * docs(chaos): document serial-execution invariant in harness lock helpers ### Bug Fixes * **governance:** close actor_mapping pseudonymization bypass ([#150](#150)) ([afed31d](afed31d)), closes [#5](#5) [#6](#6) [#1](#1) [#2](#2) [#3](#3) [#4](#4) [#1](#1) [#2](#2) [#3](#3) [#4](#4) [#1](#1) [#2](#2) [#3](#3) [#4](#4) [#140](#140) [#140](#140) [#140](#140)

The revert of #150 also undid the cherry-pick of dependabot PR #140 (Go base image 1.26.2 -> 1.26.3) that was included in commit 32262dd. Without the bump, the security scan re-flags 16 Go stdlib CVEs from the 2026 disclosure cycle and the revert PR cannot pass CI. Re-applies the same single-line Dockerfile bump. Functionally identical to dependabot PR #140 (still open against develop). This bump is independent of the actor_mapping fix and should land regardless of how #150 is re-evaluated.
