+# Task 3 report — vector port and wrappers
+
+## Status
+
+Complete. Added the transport-neutral vector port, HTTP and legacy-direct wrappers, and
+routed the existing `RestSearcher` and `DirectSearcher` through them while retaining the
+canonical `VectorRecord` and `VectorHit` models.
+
+## TDD evidence
+
+- RED: `cd harness && .venv/bin/pytest tests/test_vector_port_contract.py -q`
+  - Result: collection failed with `ModuleNotFoundError: No module named
+    'tht.adapters.vector'` (expected missing-port failure).
+- GREEN: `cd harness && .venv/bin/pytest tests/test_vector_port_contract.py -q`
+  - Result: `4 passed in 0.11s`.
+
+## Verification
+
+- Required regression command:
+  `cd harness && .venv/bin/pytest tests/test_vector_port_contract.py
+  tests/test_vector_dual_key.py tests/test_search_similar_kinds.py
+  tests/test_memory_save_one.py tests/test_solved_question.py -q`
+  - Result: `26 passed in 0.12s` (fresh final run; earlier run: 26 passed in 0.16s).
+- Broader vector-focused regression:
+  `cd harness && .venv/bin/pytest tests -q -k 'vector or search_similar or
+  memory_save_one or solved_question'`
+  - Result: `29 passed, 370 deselected in 0.49s`.
+- Scoped lint:
+  `cd harness && .venv/bin/ruff check tht/ports/vector.py tht/adapters/vector
+  tht/vectorstore/reader.py tests/test_vector_port_contract.py`
+  - Result: `All checks passed!`.

+
+## Commit
+
+`ff4d662 refactor(vector): define store contract`
+
+Only the six Task 3 implementation/test files were included in the commit.
+
+## Self-review / concerns
+
+- Reader and writer clients remain separate: search and health use only the reader;
+  hashes and upsert use only the writer.
+- A missing writer reports `upsert=False` and raises `VectorWriteUnavailable`, including
+  for an empty upsert, so deployments cannot silently bypass the write credential gate.
+- Existing REST kind forwarding, legacy-404 fallback, post-filtering, global similarity
+  merge, and direct table-per-kind behavior remain delegated to their established code.
+- The port re-exports existing vector models instead of duplicating result types.
+- Non-blocking design constraint: embedded values for the new generic `upsert` contract are
+  carried in `VectorRecord.metadata['embedding']`; this preserves the existing canonical
+  record model and REST payload without changing out-of-scope `records.py`. A later direct
+  pgvector implementation may choose to formalize that field across adapters.
+
+## Authorized contract correction
+
+Status: complete. Commit: `fe8d70d fix(vector): separate write transport fields`.
+
+The earlier metadata-envelope concern above is superseded. The contract now exports a
+dedicated frozen `VectorWriteRecord` containing the canonical `VectorRecord`, precomputed
+embedding, and content hash. `VectorStore.upsert` accepts only that envelope. HTTP row
+serialization takes transport fields from the envelope and preserves `record.metadata`
+unchanged, including legitimate metadata keys named `embedding` and `content_hash`.
+
+### Corrective TDD evidence
+
+- RED: `cd harness && .venv/bin/pytest tests/test_vector_port_contract.py -q`
+  - Result: collection failed with `ImportError: cannot import name 'VectorWriteRecord' from
+    'tht.ports.vector'` (expected missing-envelope failure).
+- GREEN: `cd harness && .venv/bin/pytest tests/test_vector_port_contract.py -q`
+  - Result: `7 passed in 0.11s`.
+- Required regression suite:
+  `cd harness && .venv/bin/pytest tests/test_vector_port_contract.py
+  tests/test_vector_dual_key.py tests/test_search_similar_kinds.py
+  tests/test_memory_save_one.py tests/test_solved_question.py -q`
+  - Result: `29 passed in 0.15s` (fresh final run; earlier run: 29 passed in 0.14s).
+- Scoped lint:
+  `cd harness && .venv/bin/ruff check tht/ports/__init__.py tht/ports/vector.py
+  tht/adapters/vector tht/vectorstore/reader.py tests/test_vector_port_contract.py`
+  - Result: `All checks passed!`.
+- Whitespace check: `git diff --check`
+  - Result: exit 0, no output.
+
+### Corrective self-review
+
+- A real `evidence_records(...)` canonical builder record is serialized in the contract tests.
+- Collision coverage proves semantic `embedding` and `content_hash` metadata survive while
+  distinct envelope values occupy the RPC row's top-level transport fields.
+- Reader health/search still use only the reader client; hashes/upsert still use only writer.
+- Existing kind forwarding, legacy 404 fallback, post-filtering, similarity merge, and direct
+  search behavior remain unchanged and covered by the required regression suite.
+- The tracked plan, regenerated Task 3 scratch brief, port exports, adapter signature, and this
+  report now consistently describe `VectorWriteRecord`.
+- Concerns: none known.

+
+# Task simple-config-3 report — one bundle for local-vector and preprocess
+
+## Status
+
+Complete. Local pgvector bootstrap, reconciliation, migration, and preprocess services now
+mount only `/run/secrets/thothii.secrets`. `deploy/vector/secret-policy.sh` validates the
+whole bundle (allowlist, duplicate/empty/unknown keys, comments/blank lines, mode and symlink
+policy) and returns only the requested value. The core entrypoint exposes DWH/vector/CA values
+to the harness and materializes short-lived 0600 password files for workspace resolution.
+
+## TDD evidence
+
+- RED: `./scripts/test-preprocess-compose-config.sh` failed on the pre-existing
+  `vector_reader_password` Compose secret declaration.
+- GREEN: the same command passes after the bundle conversion and verifies local-vector
+  workspace interpolation and shared secret mounts.
+- Added bundle parser regressions to `./scripts/test-vector-secret-policy.sh`: comments/blank
+  lines are accepted and an unrelated duplicate key is rejected.
+
+## Verification
+
+- `./scripts/test-vector-secret-policy.sh` — passed.
+- `./scripts/test-preprocess-compose-config.sh` — passed.
+- `./scripts/test-vector-backup-restore-safety.sh` — passed.
+- `./scripts/test-default-compose.sh` — passed.
+- `./scripts/test-container-deployment.sh` — passed.
+- `./scripts/local-vector-smoke.sh` — passed (real Docker; bootstrap rotation, role
+  reconciliation, migration, persistence and restart).
+- `./scripts/preprocess-smoke.sh` — passed (real Docker; unchanged rerun, mutation, DWH job,
+  ACTIVE publication and cleanup).
+- `git diff --check` and `sh -n` gates — passed.
+
+## Commit
+
+Pending: `feat(compose): use one secret bundle for local services`.
+
+## Concerns
+
+The rotation helper still accepts old/new scratch files because that is its explicit CLI
+contract; the smoke script keeps those files outside Compose and mounts only the bundle.
