Ticket

Closes #682. python/examples/test_audio_to_audio.py still judged against the pre-alignment criteria, including "The agent identifies or guesses the voice is male" - voice-gender classification, which is non-deterministic and is not the capability the example tests.

Premise, re-checked on current main

Still true, and the interesting part is why it survived. Since the ticket was filed, #680 built real machinery for this: javascript/examples/vitest/tests/helpers/audio-judge-criteria.ts holds the criteria, and audio-judge-criteria-parity.test.ts keeps the Python copy byte-identical and asserts both JS siblings actually pass the constant to their judge rather than an inline array.

That machinery covers three siblings. test_audio_to_audio.py is not one of them, so it drifted for a year with nothing to notice. The ticket's option 1 ("update it to use the same criteria") fixes today's file; putting it inside the parity set is what stops the next one.

Change

  • The Python criteria move out of test_audio_to_text.py into python/examples/helpers/audio_judge_criteria.py and are exported from the helpers package, mirroring the JS helper. One copy per language instead of one per test file.
  • Both Python examples import it. test_audio_to_audio.py drops its own two criteria.
  • The vitest parity guard reads the new module and keeps the one check that genuinely spans both languages: the two constants stay byte-identical.
  • The shared criteria are immutable, and the guard checks the object the examples actually import, helpers/__init__.py included: the Python copy is a tuple, the JS copy is as const. Every other guard here watches the name, and mutating the object binds no name, so an AUDIO_JUDGE_CRITERIA.append(...) in an example would have handed the judge a drifted criterion with all of them green. Making the object immutable removes the move rather than enumerating the ways to spell it, and unlike a name-based check it holds through an alias.
  • Whether the Python siblings actually use theirs is checked in Python, by python/tests/test_audio_example_judge_criteria.py, which walks each example's AST. It inspects every JudgeAgent(...) call and its criteria argument, and requires the criteria name to be bound exactly once in the file and by an import, with list never rebound. Text matching could not see a second judge with an inline list, a parameter or for target or walrus that shadows the name, or an import that stopped coming from helpers. It parses files, so no keys and no network, and it runs in python-ci's unit step.

The criteria strings themselves are unchanged, which the parity test enforces.

The prompt in test_audio_to_audio.py stays as it is and reads coherently against the new criteria: it asks the agent to answer the question in the audio (criterion 1) and to mention it received audio (criterion 3). Prompt/criteria coherence in the other three siblings is #681's scope, not this one.

Evidence

The strongest check is that the extended guard fails on exactly the state the ticket reports. With test_audio_to_audio.py restored to its origin/main content:

FAIL  audio-judge-criteria-parity.test.ts > keeps test_audio_to_audio.py on the shared constant, not an inline copy
AssertionError: test_audio_to_audio.py must pass AUDIO_JUDGE_CRITERIA to the judge, not an inline list

With the fix in place:

pnpm -F vitest-examples exec vitest run tests/audio-judge-criteria-parity.test.ts
  Test Files  1 passed (1)
       Tests  4 passed (4)

uv run pytest tests/ -m "not integration"
  1328 passed, 10 skipped         # 12 of them the new guard

uv run pytest examples/test_audio_to_audio.py examples/test_audio_to_text.py --collect-only -q
  2 tests collected

uv run pyright examples/test_audio_to_audio.py examples/test_audio_to_text.py examples/helpers/
  0 errors, 0 warnings, 0 informations

eslint tests/audio-judge-criteria-parity.test.ts     clean

Resolved at runtime, not just read off the page: importing helpers gives 3 criteria, and parsing the JS constant out of audio-judge-criteria.ts and comparing gives byte-identical to JS: True.

The guard is deterministic (file read plus parse, no API keys, no network), so it runs in CI unlike the live examples it protects.

Mutation testing

Mutation Result
python constant drifts one word from JS CAUGHT
a second judge in the file gets an inline list CAUGHT
either sibling pastes an inline criteria list back CAUGHT
the judge is given no criteria at all CAUGHT
the constant is re-declared inside a sibling CAUGHT
the import stops coming from helpers CAUGHT
the constant is imported under an alias CAUGHT
a parameter shadows the constant CAUGHT
a for target shadows the constant CAUGHT
a walrus shadows the constant CAUGHT
a with ... as shadows the constant CAUGHT
an except ... as shadows the constant CAUGHT
a lambda parameter shadows the constant CAUGHT
a second import rebinds the constant CAUGHT
the list builtin is shadowed CAUGHT
the shared constant reverts to a mutable list CAUGHT
an example appends to the shared criteria CAUGHT (pyright)
an example aliases the constant, then appends CAUGHT (pyright)
an example assigns to one criterion by index CAUGHT (pyright)
the helpers facade exports a stale list beside the tuple CAUGHT
the facade exports a genuine copy, (*_shared,) CAUGHT
the facade exports a copy with one criterion drifted CAUGHT

The last twelve came out of review. The first version of this guard matched source text, which proves one occurrence rather than the property; a later version checked only assignment-shaped rebindings; and the version after that still watched only the name, so mutating the object behind it escaped (verified: 10 passed with the exact wording #680 removed appended back on). CPython's own symtable answers the binding cases without an enumeration to get wrong, and an immutable object answers the mutation cases without one either.

One near-miss is worth recording, since it looked like an escape and was not. The first copy mutation tried was AUDIO_JUDGE_CRITERIA = tuple(_shared), which passed the identity check. That is CPython returning its argument unchanged: tuple(t) is t holds for an exact tuple, as does t[:] is t. There was no copy to catch. (*_shared,) does build a new tuple, and the check fails on it.

The four (pyright) rows are labelled rather than folded in: pytest tests/ alone does not catch them, uv run pyright . does, and python-ci runs both in the same job with examples/ inside pyright's scope. At runtime the interpreter raises AttributeError regardless.

Pre-existing, not from this branch

javascript-ci is red on main and red here, with the same file failing in both, and it is not one this PR touches:

main   run 32476011706 (76ee430e)      this branch  run 32480323868 (ab2ae7d9)
  tests/scenario-expert-realtime.test.ts               (same, and the only one)

It is a live realtime example. The rest of that job is 34 passed | 21 skipped, and audio-judge-criteria-parity.test.ts is among the passing four-test files. python-ci, which runs both pytest tests/ and pyright ., is green on this branch, so every guard this PR adds is verified in CI rather than only locally.

Earlier pushes on this branch saw five live files failing, on main and here alike; that set shrank to one on both sides. These examples call real models, so which of them fail varies run to run. What stays constant is that the set matches main's.

Locally tsc --noEmit in examples/vitest reports TS2688: Cannot find type definition file for 'yauzl'. That is this box's install, not the branch: the same error appears with origin/main's copy of the only TypeScript file this PR touches, and CI's own build step passes.

… criteria (#682)

Three of the four audio examples judge against one aligned set of criteria,
enforced across languages by audio-judge-criteria-parity.test.ts. The fourth,
python/examples/test_audio_to_audio.py, still carried the pre-alignment pair,
including "The agent identifies or guesses the voice is male" - a
non-deterministic property that is not the capability under test.

It sat outside the parity set, so nothing noticed. The set is what makes the
alignment stick, so the fix is to put the file in it rather than to copy the
strings across a fourth time.

The Python criteria move from test_audio_to_text.py into
python/examples/helpers/audio_judge_criteria.py, mirroring the JS helper, so
there is one copy per language rather than one per test file. The parity guard
reads the new module and now also asserts both Python siblings hand the judge
that constant, the check it already made for the two JS siblings.

Annotate the shared criteria constant and update the parity parser.

AUDIO_JUDGE_CRITERIA is an uppercase constant without a Final annotation. Add Final[list[str]]. Update the regular expression in javascript/examples/vitest/tests/audio-judge-criteria-parity.test.ts Line 48 at the same time. That expression currently accepts only AUDIO_JUDGE_CRITERIA = [.

+const match =
+  /^AUDIO_JUDGE_CRITERIA(?:\s*:\s*[^=]+)?\s*=\s*\[\n(.*?)^\]$/ms.exec(source);

As per coding guidelines, use Final for constants that should not be reassigned.

Comment thread javascript/examples/vitest/tests/audio-judge-criteria-parity.test.ts Outdated
The text guard could only prove that one occurrence in a file names the shared
constant. It could not see a second JudgeAgent in the same file with an inline
list, a local rebinding that shadows the import, an aliased import, or an
import that stopped coming from `helpers` - each of which leaves the example
judging against something other than the shared criteria while the guard stays
green.

Checked in the language where it can be checked properly. The new pytest walks
each audio example's AST and inspects every JudgeAgent call, its `criteria`
keyword, the import that introduced the name, and any rebinding of it. It
parses files, so it needs no keys and runs in python-ci's unit step alongside
the rest of tests/.

The vitest guard keeps the one check that genuinely spans both languages, the
byte-identity of the two constants, and points at the Python guard for usage.

Comment thread python/tests/test_audio_example_judge_criteria.py
…ts assignments

Checking `Assign`/`AnnAssign`/`AugAssign` covered the obvious way to shadow the
imported constant and missed the rest. A parameter, a `for` target, a walrus, a
`with ... as`, an `except ... as`, a second import or a lambda argument all bind
the name just as well, and each leaves the judge reading something else while
the call site still spells AUDIO_JUDGE_CRITERIA. A shadowed `list` does the same
to the `list(...)` form the guard accepts.

Collects every binding the module makes, by any means, and requires the criteria
name to be bound exactly once and by an import, and `list` never. That answers
all of those without resolving scopes, which is the part that would have been
easy to get subtly wrong.

…name

Walking the AST for binding forms means enumerating them, and the enumeration
kept turning out short: assignment, then parameters and for-targets and walrus
and with-as and except-as, then def and class, then match patterns. Each round
of that is a guard that reads complete and is not.

`symtable` is the binder the interpreter itself uses, so there is no list to get
wrong, and it reports nested scopes rather than only the module. A name bound
purely by an import reports imported and not assigned, and anything else binding
it as well - including a def or class of the same name - turns assigned on, so
"bound once, at module level, by an import" is stated directly rather than
inferred from the shapes that were thought of.

The audio-to-audio prompt is coherent with all three shared criteria: it asks for the audio’s specific answer and for acknowledgement of its audio format. I also confirmed the five failing JavaScript realtime examples are the same five on main; the deterministic parity test passes there. The remaining finding is a bypass in the new Python enforcement guard.

Comment thread python/tests/test_audio_example_judge_criteria.py
…unrebindable

Every guard on the audio examples watched the NAME. An importer that mutates
the object behind it binds no name, so `AUDIO_JUDGE_CRITERIA.append(...)` in an
example put a drifted criterion in front of the judge with the symbol-table
guard, the parity guard and CI all green: verified, 10/10 passing with the
exact wording #680 removed appended back on.

Fixed by removing the move rather than adding a check for it. The Python copy
is a tuple, which pyright rejects mutating in CI and the interpreter rejects at
runtime, and which holds through an alias as a name-based check could not. The
JS copy was already `as const` for the same reason; its stale cross-reference
to the pre-move Python path is corrected. The examples keep their `list(...)`
copy, since JudgeAgent wants a `List[str]`.

The parity reader now takes the tuple literal and no longer pins the
annotation, so renaming the type reads as a rename rather than as drift.

The tuple fixes the prior direct and alias-based in-place mutation path: tuples of strings cannot be changed at runtime, and the required uv run pyright . step covers python/examples/ (it is not excluded), so pyright is an appropriate backstop for the type-invalid mutation variants. I also confirmed the one failing live realtime JavaScript file is the same as main. The remaining issue is that the new runtime test does not inspect the value the examples actually import.

Comment thread python/tests/test_audio_example_judge_criteria.py Outdated
…included

The runtime guard loaded `helpers/audio_judge_criteria.py` directly while the
examples import from `helpers`, so `helpers/__init__.py` sat on the path
between them unchecked. It could import the tuple privately and export a stale
list beside it: example sources unchanged, symbol table sees a plain import,
criteria file pristine so the parity test agrees, and pyright infers the list
happily. Verified, `11 passed` and pyright clean with the criterion #680
removed exported from the facade.

The guard now imports the package the way the examples do and asserts the
exported object IS the one the submodule defines. Identity rather than
equality: a facade exporting an equal copy is a second copy, which is the
thing this whole set of guards exists to prevent.

That import pulls the package's real dependencies, so the file costs 3s
instead of 0.03s and surfaces scenario's existing `audioop` deprecation
warning. Reading `__init__.py` statically instead would be another
enumeration, and this is what the examples actually get.

Automated low-risk assessment

This PR was evaluated against the repository's Low-Risk Pull Requests procedure.

  • Scope: Move audio judge criteria into python/examples/helpers/audio_judge_criteria.py, export it from helpers.init, update Python examples to import list(AUDIO_JUDGE_CRITERIA), update the JS parity test to read the new Python module, and add python tests enforcing import usage and immutability of the criteria.
  • Exclusions confirmed: no changes to auth, security settings, database schema, business-critical logic, or external integrations.
  • Classification: low-risk-change under the documented policy.

The PR only reorganizes test/example code and test guards: it moves the audio judge criteria into a shared Python helper, updates examples to import that constant, adjusts the JS parity test, and adds unit tests that statically verify imports and immutability. It does not touch authentication/authorization, secrets, encryption, database schemas/migrations, business‑critical logic, or external API integrations, so it meets the low-risk criteria.

An approving review has been submitted by automation. The PR may merge once required CI checks pass.

No findings from re-review.

The package façade is now exercised through the same from helpers import ... path as the examples and its export is compared by identity to the criteria submodule, so the stale-list and genuine-copy façade mutations fail. The tuple of strings removes direct and alias-based in-place mutation at runtime; pyright . is a required step in the green Python CI job and its configuration includes examples/, making it an enforced check for the statically invalid mutation variants. The tuple(_shared) note is accurate: CPython returns an exact tuple unchanged, so it was not a copy; the spread-tuple case does create a second object and is caught.

I also verified the current JavaScript failure paths match the cited main run; they are unrelated live realtime examples.
