fix(py): omit test-only media fixtures from source archives - #7452
The October 31 Shipping sizes guard reports growth against its last retained October 24 baseline. The Python source archive includes test-only mux/video media fixtures after the workspace-source inclusion fix.
Approach
Exclude all test_data directories from Python source distributions while preserving the complete Rust workspace and disabled optional path dependencies. A matched local repack falls from 9,188,183 to 7,771,007 bytes, within the existing limit.
Bring the incident audit forward as requested by the maintainer. Record browser, native, generated Swift, and WASM measurements, plus the rejected browser dependency experiment. The recurring post-release refresh remains in the existing audit quest.
Impact
No public API or wire changes, compiler-profile changes, or dependency changes.
Source archives omit Rust test fixtures. Wheel builds retain their complete production sources. Rust tests/benches using those fixtures require the repository checkout.
Validation
just ci passes.
Release wheel built from the reduced archive, installed in a fresh venv, and imported successfully.
All-feature Cargo metadata resolves from the extracted archive.
Reproduced every October 31 browser bundle byte count.
Candidate ordered-map adaptation passed ten ledger tests; five alternating Chromium rounds rejected its throughput cost.
Fresh WASM baseline and shipped C/Swift archive inspection recorded in the audit.
Alternatives
Narrowing workspace inclusion risks the optional-path dependency failures fixed by moq-dev/moq#6867. The smaller ordered-map candidate slows common ledger workloads. Changing native optimization profiles still requires the existing FFI/codec throughput study.
Follow-ups
JS/C/Swift growth remains attributed in the audit. moq-dev/moq#7400 already addressed the catalog-serialization lead; the FFI-profile quest owns the remaining larger reduction lead. No size threshold or artifact history changed.
Merge with main
Merged main at 406ab9a272. The quest/m2/audit-size.md conflict kept this PR's audit and took main's WASM removal (moq-dev/moq#7475): the local WASM baseline is replaced by main's note that there is no WASM row to repeat. The link to the deleted catalog publish quest now cites moq-dev/moq#7400. Per CodeRabbit, the shipping table now states that JS rows are synthetic first-load bundles from sh/size/bundles.ts, not uploaded artifacts.

Audit the shipping-size growth against the retained October 24 baseline and record measured alternatives without changing the guard or runtime behavior.

No actionable bugs found. The sdist-only fixture exclusion is a focused fix that preserves workspace/path-dependency inclusion and leaves wheel packaging unchanged. The inspected mux/video fixture consumers are test-gated or benchmarks; requiring a checkout for those tests is consistent with the stated scope. Retaining the existing dependency and optimization profiles is preferable to mixing unproven runtime trade-offs into this packaging fix.
Verification limits: static inspection of the changes, fixture references/test gating, and source-install workflow. I did not build an sdist or wheel, run tests, or independently reproduce the audit's size/performance measurements.

pyproject.toml sdist exclude — broadens the sdist-only exclusion from the single moq-audio conformance corpus to **/test_data/**, dropping all Rust media fixtures (mux fmp4/ts/mkv, video frame/decode) from the source archive while keeping the rs/**/* workspace inclusion that #6867 requires for path-dependency resolution.
quest/m2/audit-size.md — records the pre-cut incident audit (Oct 24 vs Oct 31 shipping comparison, Python packaging analysis, browser first-load attribution and the rejected ordered-map candidate, native/binding attribution) and reframes the quest as the recurring post-release refresh.
I independently checked that every test_data directory (all six live under rs/**) is referenced only via include_bytes! inside #[cfg(test)] modules or test-gated features, so no source-install, wheel-build, or build.rs path can need them. I also confirmed the guard in sh/size/report.py:32 fails only on growth, so the reduced archive cannot trip a shrink check.

Walkthrough
The source-distribution configuration now excludes all test_data directories. The size audit records updated comparisons and attribution for Shipping artifacts, including Python source archives, browser bundles, native packages, generated bindings, and WASM.
Merge Risk: Low · up to 6c35c
The remaining issues affect the reliability and reproducibility of the size audit, but do not affect shipped runtime behavior.

The audit reports only medians. Add the five per-round samples, the candidate patch, the exact benchmark and test commands, source and build identities, hardware, and execution mode. Without these details, readers cannot independently check the A/A spread or reproduce the decision to retain sorted-btree.
The ten-test result and the Current/A/A/Candidate comparison direction are already recorded.

On the CodeRabbit nitpick about adding per-round ledger samples, the candidate patch, and hardware details to quest/m2/audit-size.md: I am not taking this. The quest file is a plan for the next audit run, not a lab notebook. It already records the benchmark, the browser version, the round count, the medians, the A/A control, and the decision to keep sorted-btree. That decision changed no code, so nobody needs to reproduce it before this lands. Raw samples would only make the plan harder to read.
Landing summary: this PR stops Python source archives from shipping the test-only test_data media fixtures. A matched local repack goes from 9,188,183 to 7,771,007 bytes. The PR also records the pre-cut size audit in quest/m2/audit-size.md.
Changes made during merge:
Merged main. The audit keeps the change from moq-dev/moq#7475, which removed WASM support, so it now has no WASM row.
Replaced the link to the deleted catalog publish quest with moq-dev/moq#7400.
Fixed the CodeRabbit finding: the audit now labels the JS rows as synthetic bundles, not uploaded artifacts.
Declined the nitpick asking for raw benchmark samples, with the reason in an earlier comment.
The Codex local review of 273ac25b49 found nothing. just ci passed locally and the required checks pass.
codex / Codex land fixer: Requeued unchanged: Healthy relative to the reported failure; batch failed on PR #7467 controller-test clock lint, not a flaky test.
