- Fix BM25 tokenizer test: add @example for Unicode ligature U+FC5E that decomposes to combining marks under NFKC, producing empty vector - Fix flaky setup test: bump API test rate limit to 1M req/min so Hypothesis 10k+ examples don't hit 429 - Add suppress_health_check to fuzz profile so Hypothesis doesn't abandon slow tests before reaching max_examples - Add extreme profile (500k examples) for overnight fuzzing sessions - Make wall-clock guardrail skip when fuzz profile is active - Update CLAUDE.md: fuzz command uses --timeout=0 and drops -k properties to cover all 46 files with @given decorators
- Refactor test_description_normalization_invariants to test normalize_description directly instead of full HTTP round-trip (13s -> 0.25s) - Reduce subprocess timeout test: ping -n 3 -> python sleep, killed after 0.5s (5.74s -> 0.52s) - Reduce deep_merge property test strategy complexity: max_leaves 20->5, max_size 8->5, max_examples 100->50 (2.3s -> 0.58s) - Reduce stagnation fingerprint property tests: max_examples 200->50 (1.4s -> 0.17s) - Fix health prober test: bypass interval_seconds=1 to avoid real 1s sleep between probe cycles (1.22s -> 0.21s)

Code Review
This pull request enhances the property-based testing infrastructure by introducing an 'extreme' Hypothesis profile for deep fuzzing and optimizing existing property tests to improve execution speed. Key changes include increasing API rate limits for tests, disabling wall-clock limits during fuzzing sessions, and refactoring specific tests to reduce overhead. Feedback highlights that the wall-clock limit bypass should be extended to include the newly added 'extreme' profile to prevent false failures during long-running sessions.

The _FUZZ_PROFILE_ACTIVE check should also include the newly added extreme profile. Since the extreme profile runs 500,000 examples per test, it will almost certainly exceed the 8-second wall-clock limit for unit tests, causing them to fail incorrectly when this profile is active.

Pull request overview
Updates the Python test suite’s Hypothesis fuzzing infrastructure and reduces runtime of several slow unit/property tests, primarily by adjusting Hypothesis profiles/strategies and removing expensive HTTP round-trips in a property test.
Changes:
- Added/updated Hypothesis profiles (
fuzz, newextreme) and adjusted the unit-test wall-clock guardrail behavior during fuzzing. - Refactored
test_description_normalization_invariantsto testnormalize_description()directly and raised API test fixture rate limits to avoid 429s during fuzz runs. - Reduced property-test workload/complexity and sped up a few slow unit tests (subprocess timeout test, health prober loop test).

The wall-clock guardrail skip is keyed only off HYPOTHESIS_PROFILE == "fuzz", but this PR also adds an extreme profile intended for long-running runs. As written, running with HYPOTHESIS_PROFILE=extreme will still fail unit tests for exceeding _UNIT_TEST_WALL_CLOCK_LIMIT, which seems contrary to the intent of adding an overnight fuzz profile. Consider broadening the check to treat both fuzz and extreme (or any non-ci profile) as exempt, or derive the flag from the loaded Hypothesis profile rather than a single env-var value.

On Windows this test now shells out to command="python", which can be missing on PATH depending on how the test environment is set up (e.g. only py launcher available). Since the test suite is already running under a specific interpreter, it’s more reliable to invoke that interpreter (e.g. via sys.executable) to avoid PATH-related flakes.

There was a problem hiding this comment.
This test reaches into ProviderHealthProber’s private state (prober._interval = 0) and intentionally violates the constructor’s validation (interval_seconds must be >= 1). That makes the test more brittle to refactors (e.g. renaming the attribute, adding invariants) and slightly changes behavior inside _probe_all (eligibility checks use _interval). Prefer avoiding private mutation here (e.g. keep interval_seconds=1 and mock/patch the wait/sleep between cycles so the loop advances without a real 1s delay).

| - **Property-based testing**: Python uses [Hypothesis](https://hypothesis.readthedocs.io/) (`@given` + `@settings`), React uses [fast-check](https://fast-check.dev/) (`fc.assert` + `fc.property`), Go uses native `testing.F` fuzz functions (`Fuzz*`). Hypothesis profiles configured in `tests/conftest.py`: `ci` (deterministic, `max_examples=10` + `derandomize=True` -- fixed seed per test, same inputs every run), `dev` (1000 examples), `fuzz` (10,000 examples, no deadline -- for dedicated fuzzing sessions). Controlled via `HYPOTHESIS_PROFILE` env var. `.hypothesis/` is gitignored. Failing examples are persisted to `~/.synthorg/hypothesis-examples/` (write-only shared DB, survives worktree deletion) via `_WriteOnlyDatabase` in `tests/conftest.py`. | ||
| - **Hypothesis workflow**: CI runs 10 deterministic examples per property test (`derandomize=True` -- same inputs every run, no flakes). Random fuzzing runs locally: `HYPOTHESIS_PROFILE=dev uv run python -m pytest tests/ -m unit -n 8 -k properties` (quick, 1000 examples) or `HYPOTHESIS_PROFILE=fuzz uv run python -m pytest tests/ -m unit -n 8 -k properties` (deep, 10,000 examples, no deadline). When Hypothesis finds a failure, it is a **real bug** -- the shrunk example is saved to `~/.synthorg/hypothesis-examples/` for analysis but is **not replayed** automatically (that would block all test runs). Do NOT just rerun and move on. Read the failing example from the output, fix the underlying bug, and add an explicit `@example(...)` decorator to the test so the case is permanently covered in CI. | ||

The testing docs still list Hypothesis profiles as only ci, dev, and fuzz, but tests/conftest.py now also registers an extreme profile. Updating this section to mention extreme (and when to use it) will keep CLAUDE.md consistent with the actual test configuration.

- Around line 345-347: The test mutates private validated state by setting
prober._interval = 0; instead, update the HealthProber implementation or the
test to avoid touching internals: add a constructor parameter (e.g.,
min_interval_override or allow_test_interval) to the HealthProber class so tests
can create an instance with interval < 1 without breaking validation, or alter
the test to use unittest.mock.patch.object to mock only the instance's
asyncio.wait_for/asyncio.sleep behavior (targeting the prober instance methods
used in HealthProber.run) and/or mock time.monotonic() for deterministic timing;
change references to prober._interval in the test to pass a small interval via
the new constructor arg or rely on the instance-scoped mock instead of directly
mutating _interval.

Learning: Applies to src/synthorg/**/*.py : `RetryConfig` and `RateLimiterConfig` are set per-provider in `ProviderConfig`. Retryable errors (`is_retryable=True`): `RateLimitError`, `ProviderTimeoutError`, `ProviderConnectionError`, `ProviderInternalError`. Non-retryable errors raise immediately without retry. `RetryExhaustedError` signals that all retries failed — the engine layer catches this to trigger fallback chains. Rate limiter respects `RateLimitError.retry_after` from providers — automatically pauses future requests.

Avoid mutating validated private state; use proper deterministic mocking instead.
Directly setting _interval = 0 bypasses constructor validation (which requires interval_seconds >= 1) and makes this test brittle to internal refactors. However, the proposed fix of patching synthorg.providers.health_prober.asyncio.wait_for at module level is problematic: it would also affect the test's own await asyncio.wait_for(done_event.wait(), timeout=10) call on line 366, causing it to fail unexpectedly.
Instead, consider:
- Adding a constructor parameter to allow overriding the minimum interval for testing (e.g.,
allow_test_interval=True) - Or using
unittest.mock.patch.objectto mock only the instance's timeout behavior in the run loop - Or passing a very small interval (requires relaxing the
>= 1constraint for test scenarios)
Per coding guidelines, timing-sensitive tests should mock time.monotonic() and asyncio.sleep() for determinism, not mutate internals.

In `@tests/unit/providers/test_health_prober.py` around lines 345 - 347, The test
mutates private validated state by setting prober._interval = 0; instead, update
the HealthProber implementation or the test to avoid touching internals: add a
constructor parameter (e.g., min_interval_override or allow_test_interval) to
the HealthProber class so tests can create an instance with interval < 1 without
breaking validation, or alter the test to use unittest.mock.patch.object to mock
only the instance's asyncio.wait_for/asyncio.sleep behavior (targeting the
prober instance methods used in HealthProber.run) and/or mock time.monotonic()
for deterministic timing; change references to prober._interval in the test to
pass a small interval via the new constructor arg or rely on the instance-scoped
mock instead of directly mutating _interval.
