Inline comments:
In `@docs/superpowers/specs/2026-08-12-pgsql-user-sync-design.md`:
- Around line 355-358: Escape the leading “#” in the PR reference within the
integration-test dependency paragraph so Markdownlint does not interpret it as a
heading, while preserving the reference text and surrounding explanation.
In `@test/tap/tests/pgsql-user-sync-t.py`:
- Around line 70-79: Update admin_row to select the backend-specific row
deterministically by adding the appropriate backend filter to its SQL query when
reading runtime_pgsql_users (and the corresponding mysql_users table if
applicable). Preserve the existing username filtering and return shape while
ensuring the returned row represents backend=1 rather than an arbitrary
frontend/backend half.
In `@test/tap/tests/pgsql-user-sync-unit-t.py`:
- Around line 9-11: Rename the test wrapper currently invoking unittest via
subprocess.call from pgsql-user-sync-unit-t.py to pgsql-user-sync-unit-t so it
matches the runner’s test/tap/tests/*-t discovery glob, and preserve its
executable permissions.
In `@tools/pgsql_user_sync/create_source_function.sql`:
- Around line 35-41: Update tools/pgsql_user_sync/create_source_function.sql
lines 35-41 to replace pg_has_role with a direct pg_catalog.pg_auth_members
membership check and add NOT r.rolsuper; update
docs/superpowers/specs/2026-08-12-pgsql-user-sync-design.md lines 83-86 and
tools/pgsql_user_sync/README.md lines 59-62 to document the explicit superuser
exclusion and direct membership check.
In `@tools/pgsql_user_sync/proxysql_pgsql_user_sync.py`:
- Around line 826-833: The disk-save exception handling in the sync flow must
preserve the successful runtime load and report a partial outcome instead of
raising _sync_failure. Update the block around admin.save_to_disk() so it
records loaded=True, saved=False, returns the documented partial summary, and
routes through the existing nonzero exit handling while retaining the current
successful save behavior.
- Around line 500-519: The runtime table can contain a backend half with
frontend=0 for a combined main user, so comparisons must use a normalized
projection that excludes frontend. In
tools/pgsql_user_sync/proxysql_pgsql_user_sync.py lines 500-519, update the
main/runtime drift comparisons while preserving managed versus unmanaged
handling; add managed and unmanaged replace(main, frontend=0) fixtures and
no-drift/no-load assertions in
tools/pgsql_user_sync/tests/test_pgsql_user_sync.py lines 411-423; update the
admin_row query in test/tap/tests/pgsql-user-sync-t.py lines 70-79 to constrain
backend=1 for deterministic selection.
In `@tools/pgsql_user_sync/tests/test_pgsql_user_sync.py`:
- Around line 411-423: Add a test near test_managed_runtime_drift_requires_load
and test_inactive_main_row_is_expected_absent_from_runtime that constructs the
runtime user with frontend=0 and backend=1, matching the real
runtime_pgsql_users shape instead of using replace(main, ...). Build the plan
with that runtime row and assert it has no actions and does not require a load,
covering the defect in the runtime comparison logic.

File: test/tap/tests/unit/gtid_set_unit-t.cpp:14-17
Timestamp: 2026-04-01T21:27:03.216Z
Learning: In ProxySQL's unit test directory (test/tap/tests/unit/), test_globals.h and test_init.h are only required for tests that depend on the ProxySQL runtime globals/initialization (i.e., tests that exercise components linked against libproxysql.a). Pure data-structure or utility tests (e.g., ezoption_parser_unit-t.cpp, gtid_set_unit-t.cpp, gtid_trxid_interval_unit-t.cpp) only need tap.h and the relevant project header — omitting test_globals.h and test_init.h is correct and intentional in these cases.

Timestamp: 2026-04-11T13:17:55.508Z
Learning: When using GitHub-flavored Markdown headings, be aware that an em-dash surrounded by spaces (written as ` — `) affects the generated anchor/slug: GitHub replaces spaces with hyphens and removes non-alphanumeric punctuation, which can produce double hyphens (e.g., `## Foo — bar` → anchor `#foo--bar`, not `#foo-bar`). If you reference these anchors (e.g., internal links), ensure the expected slug matches this behavior.

Timestamp: 2026-04-11T13:17:55.509Z
Learning: When reviewing GitHub-flavored Markdown links/anchors, remember that heading-to-anchor slug generation treats spaces as hyphens and removes punctuation. If a heading contains an em-dash surrounded by spaces (e.g. ` — `), the slugs can legitimately include a double hyphen where the two surrounding space-runs become `-` on either side of the removed em-dash (e.g. `...vocabulary--read...`). Do not flag double-hyphens in anchor links for em-dash-containing headings as errors; they reflect GitHub’s correct slug behavior.

Timestamp: 2026-08-11T12:56:13.170Z
Learning: In `docs/superpowers/plans/2026-08-11-ed25519-authentication.md`, the historical-artifact notice states that embedded expected outputs are plan-time values. Review-driven changes can modify the MariaDB Ed25519 implementation and TAP assertion counts after the plan is written. The shipped implementation and tests are authoritative, so reviewers must not require retroactive synchronization of plan-time expected outputs.

Timestamp: 2026-08-12T05:27:01.785Z
Learning: For ProxySQL isolated regression tests that use a fresh explicit `INFRA_ID`, `test/infra/control/ensure-infras.bash` detects the absent `proxysql.${INFRA_ID}` container and invokes `test/infra/control/start-proxysql-isolated.bash` before it provisions configuration. Do not invoke `start-proxysql-isolated.bash` again after `ensure-infras.bash`, because it removes the named container and its `proxysql.db`, which discards the provisioned configuration. The binary at `src/proxysql` is mounted when the container is initially created.

Learning: In `docs/superpowers/plans/2026-08-11-ed25519-authentication.md`, the historical-artifact notice states that embedded expected outputs are plan-time values. Review-driven changes can modify the MariaDB Ed25519 implementation and TAP assertion counts after the plan is written. The shipped implementation and tests are authoritative, so reviewers must not require retroactive synchronization of plan-time expected outputs.

There was a problem hiding this comment.
For a managed role whose rolpassword is a SCRAM verifier, assigning that verifier as the password of a combined frontend/backend user makes authentication through ProxySQL unusable for queries. ProxySQL can validate the frontend SCRAM exchange from the verifier, but PgSQL_Connection::connect_start() subsequently supplies this stored value to libpq as the backend password; a SCRAM verifier cannot act as the client's plaintext secret or ClientKey, so backend connection establishment fails. The integration test only logs in directly to PostgreSQL and checks the ProxySQL tables, so it does not expose this failure. These verifier-backed rows need to be frontend-only unless a separately usable backend credential is provided.

There was a problem hiding this comment.
When SAVE PGSQL USERS TO DISK fails after a successful apply/load, the run correctly reports partial, but the next scheduler invocation sees matching main/runtime snapshots and takes this early return without attempting another save. Consequently, a transient save failure can leave the synchronized users unpersisted indefinitely, and a ProxySQL restart before another role change restores stale disk state. The retry path needs retained dirty state or another way to load and save again when persistence is still pending.

P2: The plan's source-function SQL uses `pg_has_role(r.oid, 'proxysql_auth_managed', 'member')` with no superuser filter, contradicting the spec (same batch) which mandates direct `pg_auth_members` membership and explicit superuser exclusion to prevent importing `postgres`. `pg_has_role` 'member' matches indirect membership and returns true for superusers, so this SQL can import roles the design excludes. Add `AND NOT r.rolsuper` and match the spec's direct `pg_auth_members` predicate.</violation>

<violation number="1" location="tools/pgsql_user_sync/create_source_function.sql:18">
P2: When `proxysql_auth_reader` already exists, this `CREATE ROLE` block is skipped and no later `ALTER ROLE` reapplies LOGIN/password settings. Reruns cannot rotate credentials and can leave the sync account unusable. Add an unconditional `ALTER ROLE proxysql_auth_reader ... PASSWORD ...` after the DO block.</violation>
<violation number="2" location="tools/pgsql_user_sync/create_source_function.sql:20">
P2: This line uses a hard-coded placeholder as an actual password value. If an operator runs the script unchanged, it creates a predictable credential. Require a runtime-provided secret so installation fails when no password is supplied.</violation>
<violation number="3" location="tools/pgsql_user_sync/create_source_function.sql:56">
P2: The schema and function are created in the currently connected database, but `GRANT CONNECT ON DATABASE postgres` hard-codes the database name. When installed into a non-`postgres` database (the README and file header both allow this), the reader is granted CONNECT on the wrong database and cannot log in. Grant CONNECT on the current database instead so the grant always matches where the schema/function were created.</violation>

<file name="test/tap/tests/pgsql-user-sync-t.py">
<violation number="1" location="test/tap/tests/pgsql-user-sync-t.py:253">
P3: The ownership-marker assertion runs `json.loads(main_row[4])` without guarding a NULL/empty `attributes` value. When that parse fails (or any later admin query raises), the single outer `except Exception` collapses every remaining `tap.check` into one generic "real PostgreSQL to ProxySQL synchronization completes" failure, discarding the granular diagnostics the rest of the test builds. Guard the attributes parse (treat None/'' as no marker) and scope exceptions to setup steps rather than the whole verification body so individual assertions still report independently.</violation>

<violation number="1" location="tools/pgsql_user_sync/proxysql_pgsql_user_sync.py:879">
P3: `_sync_failure` is a redundant wrapper that is identical to the existing `_error` helper (it just returns `_error(message)`). The extra name adds no value and makes the error-producing paths inconsistent with the rest of the module, which calls `_error(...)` directly. Replace the four `raise _sync_failure(...)` calls with `raise _error(...)` and delete the helper.</violation>

P2: This test appears to exercise several invalid fields (connect_timeout=-1, default_hostgroup=-1, missing_role_action=remove, adopt_existing_users=maybe), but the SyncError fires at [source].port = 0 first. Because load_config() validates the source section - and its endpoint - before the sync section, the other invalid values are never parsed, and the single generic assertRaises(SyncError) can't distinguish which field triggered it. A regression that removed the connect_timeout, default_hostgroup, missing_role_action, or adopt_existing_users validation would go undetected; none of those is validated in any other test. Split the invalid values into separate configs (with a valid port) and assert each specific rejection, so each validation is actually exercised.</violation>

In `@test/tap/Makefile`:
- Around line 6-22: Update the tests target in the Makefile so
pgsql_user_sync_assets is a prerequisite of tests, ensuring staging completes
before pgsql-user-sync-t.py runs in direct or parallel test executions. Keep the
existing debug and asset target behavior unchanged.

Nitpick comments:
In `@test/tap/Makefile`:
- Around line 15-22: Reduce the pgsql_user_sync_assets recipe to at most five
lines by defining make variables for the canonical asset paths and replacing the
individual copy commands with a generic copy step, while preserving the existing
destination layout and asset set.

Learning: Applies to test/tap/tests/**/*.cpp : To add a new TAP test, add the `<testname>-t.cpp` file and register it in `test/tap/tests/Makefile`/`groups.json`; no special Makefile target is needed because `make <testname>-t` is generated by pattern rule.

Learning: In ProxySQL's unit test directory (test/tap/tests/unit/), test_globals.h and test_init.h are only required for tests that depend on the ProxySQL runtime globals/initialization (i.e., tests that exercise components linked against libproxysql.a). Pure data-structure or utility tests (e.g., ezoption_parser_unit-t.cpp, gtid_set_unit-t.cpp, gtid_trxid_interval_unit-t.cpp) only need tap.h and the relevant project header — omitting test_globals.h and test_init.h is correct and intentional in these cases.

Learning: In `docs/superpowers/plans/2026-08-11-ed25519-authentication.md`, the historical-artifact notice states that embedded expected outputs are plan-time values. Review-driven changes can modify the MariaDB Ed25519 implementation and TAP assertion counts after the plan is written. The shipped implementation and tests are authoritative, so reviewers must not require retroactive synchronization of plan-time expected outputs.

P3: The tests that consume the staged assets (pgsql-user-sync-t.py, pgsql-user-sync-unit-t.py) are members of the `tests` tree, but the `tests`/`tests_with_deps` targets (which build and run them) do not depend on `pgsql_user_sync_assets`. A `make tests` in a fresh checkout stages no assets, so those tests fail; under parallel `make debug -j$(nproc)` (per test/README.md) there is no guarantee the assets are staged before the tests run. Declare `pgsql_user_sync_assets` as a prerequisite of `tests`, `tests_with_deps`, and `unit_tests` instead of (or in addition to) `all`/`debug`.</violation>
<violation number="2" location="test/tap/Makefile:15">
P3: The recipe stages generated files under test/tap/pgsql_user_sync/, but nothing in .gitignore excludes them, so every `make all`/`make debug` leaves these copies showing as untracked in git status. Add a gitignore entry (e.g. `test/tap/pgsql_user_sync/`) for the staged build outputs.</violation>
