feat(#307): BoTTube provider router hardening (by Léa/Kryosys)

[Scottcjn]

Bounty #307 — provider router reliability (paid 120 RTC to kryosys-lea / RTC31ede8c0…).

New:

• generation/reliability.py — RetryPolicy, ProviderMetrics, classify_error (auth/throttled/transient/permanent), run_with_retries, metrics snapshot
• tests/test_generation_reliability.py — 3 tests (retry/fallback/error-classification)
• docs/generation_provider_reliability.md — troubleshooting + env

Modified:

• generation/worker.py — integrates reliability into submit/status/result paths

Implements all 5 bounty asks. Verified original (reliability.py not previously in repo).

⚠️ Reviewer note: worker.py was submitted as a full file (604→639L) off an unknown base — please confirm it doesn't revert recent changes before merge. Test suite not re-run in-house (author claims 3 passed).

I reviewed the provider reliability changes and focused on the maintainer note about generation/worker.py plus the new metrics path.

The PR does not appear to be a full-file revert against current origin/main: generation/worker.py is a focused 63-line contextual diff, and the recent main commits touching that file are still present in the merge-base comparison.

Validation run locally:

• python -m py_compile generation/reliability.py generation/worker.py tests/test_generation_reliability.py -> passed using bundled Python
• git diff --check origin/main...HEAD -> passed
• Manual invocation of the three new test functions -> passed
• Additional smoke: run_with_retries(..., lambda: (False, "quota exhausted")) returns ok, and the metrics snapshot records one success / zero failures

Requesting changes for one metrics issue:

generation/reliability.py:114 records every non-exception return as a provider success, but generation/worker.py:257-263 wraps provider.submit() and then treats (False, reason) as a failed provider attempt. That means a provider can reject a job normally, the worker falls back correctly, but provider_metrics_snapshot() reports successes: 1, failures: 0. I reproduced it with:

run_with_retries(
    "semantic_false_submit",
    "submit",
    lambda: (False, "quota exhausted"),
    RetryPolicy(attempts=1, base_delay_s=0, max_delay_s=0, jitter_s=0),
)

Observed result:

True (False, "quota exhausted") ok 1
{"attempts": 1, "successes": 1, "failures": 0, ...}

Could this helper accept a success predicate, or should submit-result failures be recorded/corrected before the metrics snapshot is attached to the job?

I handled the requested metrics fix in follow-up PR #1495 because the current terminal account does not have permission to push directly to the #1430 head branch.

Summary of the fix:

• run_with_retries() now accepts an optional success_predicate.
• provider.submit() results like (False, "quota exhausted") are classified and recorded as provider metric failures instead of successes.
• the generation worker passes the predicate for submit calls.
• added a regression test for the exact semantic-false case from the review.

Validation run locally:

• python3 -m py_compile generation/reliability.py generation/worker.py tests/test_generation_reliability.py
• direct invocation of all tests in tests/test_generation_reliability.py; pytest is not installed in this local environment
• git diff --check
