Pull request overview
OpenCode cannot approve yet because required coverage evidence did not pass.
Review outcome
1. HIGH .github/workflows/opencode-review.yml:1 - Coverage evidence did not prove required test/docstring evidence
-
Problem: The required coverage-evidence job result was
failure, so OpenCode cannot establish approval sufficiency for this head. -
Root cause: Automated approval is only valid when the same-head coverage-evidence job proves supported repository test suites passed and configured docstring gates passed or were advisory, or reports not applicable because no supported source files or package manifests exist. Missing, failed, skipped, unavailable, or unsupported-tooling test evidence is a blocker.
-
Fix: Install or configure the repository test/docstring evidence tooling when source files or package manifests exist, rerun the current-head coverage-evidence job, and approve only after it reports
successwith required evidence or explicit no-source not-applicable evidence. -
Regression test: Keep the approval branch checking
needs.coverage-evidence.result == successbefore posting APPROVE, and publish REQUEST_CHANGES when coverage-evidence blocker states such as cancelled, skipped, failed, unsupported-tooling, or below-100 evidence are present. -
Result: REQUEST_CHANGES
-
Reason: coverage-evidence result was
failure, so required test/docstring evidence was not proven for current head4f9473ce420f8f3ddbc0735d900ea598965dafd7. -

Verdict: REQUEST_CHANGES
The runtime on 7f421f4 is sound: constructors no longer own DDL or default seeding, catalog probes fail closed, Fernet is mandatory before PostgreSQL acquisition, exact str key text is required, Base64 decode is gone, and unencrypted durable rows are rejected at startup and on read. Schema mirrors stay byte-identical. Tenant scope is correctly not invented for deployment-global com_config / com_secrets.
This head still cannot merge. The files operators actually follow were not updated with the breaking encryption and provisioning change, and cryptography remains an extra while SecretStore now hard-requires it.
A continuation that applies those contract fixes is on cursor/bc-389287fc-f6ac-4e1c-9047-5b223d434a8e-729f. Prefer landing that branch (or cherry-picking its two commits onto this one) instead of merging 7f421f4 as-is.
Findings
Warning — public contract drift (merge-blocking)
Doctoring already states that Fernet is mandatory and that require_encryption=False is rejected. These operator files on this head still do not:
CHANGELOG.md[Unreleased]has no entry for provisioning/runtime separation, mandatory Fernet, or removal of Base64 compatibility.README.mdstill calls the Fernet key optional and still showsSecretStore(dsn)with no key. That example now fails before database acquisition.pg_llm_batch/bootstrap.pyanddocs/doctoring/bootstrap-dsn-precedence.mdstill describe an optional Fernet bootstrap key.ARCHITECTURE.mdstill says only “encrypted secrets” and does not record the new provisioning vs runtime boundary or the non-equivalent rollback to Base64-capable versions.
The repository contract requires README, operator guide, architecture, doctoring, and CHANGELOG to move together when secret, role, migration, or rollback rules change.
Warning — packaging still treats Fernet as optional (merge-blocking)
SecretStore fails closed if cryptography is missing, but pyproject.toml keeps it on the secrets extra. A default pip install . plus python -m pg_llm_batch config set-secret or _make_client() fails. The constructor error still says “optional cryptography dependency.” Promote cryptography to a core dependency and stop calling it optional in the ConfigError text.
Note — schema default still invites unencrypted SQL inserts
com_secrets.is_encrypted remains BOOLEAN NOT NULL DEFAULT FALSE. Runtime fail-closed behavior is correct, but a raw INSERT that omits the flag still creates a row that poisons the next SecretStore construction. Keep the probe; require an explicit flag in SQL guidance.
Note — write privilege is not part of the constructor probe
The catalog probe checks schema USAGE, table SELECT, and unique-key arbiter shape. set() / set_secret() can still raise raw driver errors when INSERT/UPDATE is missing. Call that out in doctoring if write-capable construction is meant to fail closed the same way unique-key gaps do.
Previous review concerns
Addressed on this head:
- Production roles documented as
NOSUPERUSER NOBYPASSRLS. - Relation kind and column-type catalog validation, not “SELECT succeeded.”
- Fernet key validated before
psycopg.connect; exactstr(no subclasses). - Integration test no longer persists an unused plaintext secret.
- Persisted encryption flag is passed through without
bool()coercion. - Default policy and
require_encryption=Falsetests now match the constructor.
Correctly not applicable:
- Binding
pg_llm_batch.tenant_scopebefore thecom_secretsreadiness query.com_secretshas no tenant discriminator or RLS. Addingset_confighere would invent a boundary the schema does not enforce.
Next action
Do not merge 7f421f4. Take the contract-sync continuation (eac7ca7 + e0e8168) or apply the same README/CHANGELOG/ARCHITECTURE/bootstrap/packaging edits here, then wait for terminal-success exact-head required checks on that unchanged SHA.

| ## Secret encryption policy | ||
|
|
||
| `SecretStore` requires Fernet encryption for every runtime construction and every newly persisted secret. A missing Fernet key, malformed key, unavailable cryptography dependency, or explicit `require_encryption=False` request fails with a fixed `ConfigError` before PostgreSQL connection acquisition. The historical `require_encryption` keyword is retained only so existing callers that explicitly pass `True` do not break at the call boundary; it is not a policy switch and cannot re-enable reversible Base64 persistence. |

This paragraph already requires Fernet and rejects require_encryption=False, but the files operators follow on this head still disagree.
On 7f421f4, CHANGELOG.md has no Unreleased entry for this break, README.md still says “optional Fernet key” and still shows SecretStore(dsn), bootstrap.py / docs/doctoring/bootstrap-dsn-precedence.md still call the key optional, and ARCHITECTURE.md does not record the provisioning vs runtime split or the non-equivalent Base64 rollback.
Update those documents on this branch, or take the continuation on cursor/bc-389287fc-f6ac-4e1c-9047-5b223d434a8e-729f, before treating this head as mergeable.

This fail-closed path is correct, but the diagnostic and packaging still call cryptography optional.
pyproject.toml on this head keeps cryptography on the secrets extra while SecretStore now hard-requires it before psycopg.connect. A default pip install . plus CLI config set-secret or embed SecretStore(...) fails here.
Promote cryptography>=50.0.0 to [project.dependencies], refresh uv.lock, and change this message to say the cryptography package is required. Do not leave [secrets] as the only documented install path.

Focused RED003183a6734d00a54f5626a64de91d86f942c59fcaused exact-head CI31900358480to fail the newrequire_encryption=Falsepre-database assertion (1 failed, 949 passed). Subsequent fixes removed Base64 persistence/decode and made Fernet mandatory.A fresh runtime-boundary audit then found that predecessor
4f9473ce420f8f3ddbc0735d900ea598965dafd7accepted a truthystrsubclass asfernet_keyand invoked its overridden.encode()before database acquisition. That could execute caller-controlled behavior and escape arbitrary lower-layer text instead of the fixed malformed-keyConfigErrorclaimed by this surface. REDa3f16fbd83525428010f216c6d859d312ba9f943adds a hostile Fernet-key subclass regression requiring bounded failure before any database access.
