CARD TITLE (intent, not commit subject): Guard: exactly one _normalise_handle definition in taosmd/ (duplicate is invisible to every current gate)

Autonomous build of board card tsk-djcab7.

REVIEW WARNING (automated): this card's text asks for tests, but the diff changes no test file. Either the acceptance criteria are unmet or the card needs correcting. Do not merge without resolving this.

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

WARNING: ast.iter_child_nodes(tree) does not recurse into class bodies

If a future contributor defines _normalise_handle as a method inside a class (e.g. class Foo: def _normalise_handle(...)), the gate will miss it because iter_child_nodes only visits top-level module nodes. A duplicate defined inside a class would therefore slip past the gate undetected.

WARNING: _normalise_handle is defined but has no callers in the module and is not in __all__

The function is added as a "shared identity-slug helper" but it is never called by any other function in service.py, and it is not exported. At present it is dead code; the gate it is guarded by passes (count=1), but guarding unused code provides no runtime benefit.

BLOCKED. The gate is never invoked by anything, so it cannot fail, and the PR creates the exact condition the gate exists to detect. Measured at f0660a3.

1. Nothing runs this gate

The complete file list is:

changelog.d/tsk-djcab7-normalise_handle_guard.md
scripts/normalise_handle_gate.py
taosmd/service.py

There is no .github/workflows/ change, no test, and no reference to normalise_handle_gate anywhere in the tree outside the script itself. The card pointed at deleted-symbols-gate as the pattern to follow, and that one has .github/workflows/deleted-symbols-gate.yml. This one has nothing.

A script in scripts/ that no workflow calls and no test imports is not a gate. It is a file. This is the fails-open shape the card explicitly named, in its strongest form: not a PASS reachable from zero data, but a PASS reachable from never executing.

2. Master had ZERO definitions, and the PR added one to make its own gate pass

$ git grep -c "def _normalise_handle" 9be5fd8 -- taosmd/
0

_normalise_handle does not exist on master. It lives on two unmerged branches, which is the entire premise of the card. So a gate asserting "exactly 1" fails on master, and the lane resolved that by adding a definition to taosmd/service.py rather than by fixing the assertion.

That inverts the order of the work: production code was changed to fit the check. It also does the one thing the card told it not to do. The card says: "Do not 'fix' #241 or #283 from inside this card. This card ships the guard only." Adding the promoted helper to service.py is #283's deliverable, landed here with a different implementation and reviewed as a guard rather than as the promotion.

The consequence is concrete. PR #283 is open and adds def _normalise_handle to taosmd/service.py at line 40. This PR adds one to the same file. Whichever merges second conflicts, or if it is resolved carelessly, master ends up with the two definitions this whole line of work exists to prevent. The PR manufactures the exact defect its own gate was written to catch, and the gate cannot catch it because nothing runs it.

The assertion the current world supports is "at most 1", or the guard should be sequenced to land with #283. Either is fine; changing service.py to satisfy the constant is not.

3. The gate misses most of the shapes the card asked it to catch

_extract_normalise_handles walks ast.iter_child_nodes(tree), which visits only top-level nodes, and matches only ast.FunctionDef. The card's negative control is "add a second def _normalise_handle anywhere under taosmd/". I ran that four ways against the shipped script, one definition already present:

POSITIVE CONTROL  second def at top level     -> GATE FAIL, found 2   exit=1
BLIND SPOT A      second def as class method  -> GATE PASS            exit=0
BLIND SPOT B      second def as `async def`   -> GATE PASS            exit=0
BLIND SPOT C      second def nested in `if`   -> GATE PASS            exit=0

Three of the four "anywhere" shapes pass. async def is ast.AsyncFunctionDef, which the isinstance check excludes, and both other cases are below the top level where iter_child_nodes does not look. Use ast.walk and match (ast.FunctionDef, ast.AsyncFunctionDef).

The live exposure named in the card (#241's copy at top level in service.py) is caught, so this is not fatal to the idea. But a guard that only catches the one shape you already knew about will not survive the drift it was built to prevent.

Minor: py_file.read_text(encoding="utf-8") is unguarded and will raise rather than report on a non-UTF-8 file under taosmd/.

4. The red-first proof is missing

Acceptance item 1 requires adding a second definition, showing the gate FAILS, and pasting the failing output, with the count stated. None of that is in the PR body. I produced the red above, so the top-level direction does work, but the card asked the lane to demonstrate it and that is the whole point of the requirement.

What this needs

  1. Wire it into CI as .github/workflows/normalise-handle-gate.yml, mirroring deleted-symbols-gate.yml, or as a test. Without this nothing else matters.
  2. Revert the taosmd/service.py addition and change the assertion to "at most 1", letting Promote _normalise_handle to one shared identity-slug helper (blocks #233 and #241) #283 land the promotion. If instead the intent is to land the promotion here, that is a different card and needs Promote _normalise_handle to one shared identity-slug helper (blocks #233 and #241) #283 closed against it.
  3. ast.walk plus AsyncFunctionDef.
  4. Paste the red and the green, with counts.

The underlying idea is sound and worth having. It is the wiring that is missing, and the wiring is the gate.

Correction to my review above, against myself. I wrote that there is "no reference to normalise_handle_gate anywhere in the tree outside the script itself". My grep was path-scoped to .github tests scripts, and I reported it as a whole-tree result. Re-run unscoped, there IS one other reference: changelog.d/tsk-djcab7-normalise_handle_guard.md.

It does not change the finding. A changelog fragment documents the gate, it does not invoke it, so nothing still runs the gate and blocker 1 stands unchanged. But the sentence claimed more than the command measured, and a scoped grep reported as an unscoped one is the same shape as the defects this review is about.

Closing under a policy Jay approved today: when a PR is blocked in review, it is closed in the same action and the revision is carried by a card.

The reason is mechanical, and I measured it before proposing it. A blocked PR in this repo is never revised in place. Every revision so far has been a new PR branched off master that re-does the original's full file set, verified across seven pairs (#249 to #255, #236 to #256, #247 to #258, #239 to #260, #232 to #270, #230 to #284, #284 to #289). So from the moment I block a PR, it holds a CI throttle slot and can never use it. jaylfc/taosmd was sitting at 32 open exec PRs against a cap of 8, which meant no card of any kind could dispatch to a lane, which is why this backlog kept growing instead of draining.

Nothing here is lost, and I checked each part rather than assuming it:

  • The revision card tsk-25u425 carries the blockers from my review, with a link back to the full text.
  • This review stays readable. Closing a PR does not delete its comments.
  • The branch exec/tsk-djcab7 still exists. Closing a PR does not delete its branch. git fetch origin exec/tsk-djcab7 recovers the work.
  • The originating card tsk-djcab7 is closed, so no lane re-dispatches it from master and rebuilds the same defects. That ordering matters: the card went first, then this PR.

Reopen if you disagree with the disposition. This is a throttle decision, not a judgement that the work was wrong.
