Summary

Adds .rusuban/: the rules and locks that Rusuban, the autopilot taking over from the maintainer's current pilot, follows on this repo. Rusuban reads them from the default branch only, never from a PR.

• rules/01-autonomy.md:
  • what the agents do alone, and what always comes to the maintainer on a card: features, UI and UX, architecture, unproven pixel or performance impact, refusals;
  • issues;
  • the two-day wait on a third party;
  • priorities and areas.
• rules/02-merging.md:
  • what may merge alone, for every author: bug fixes, translations other than English, documentation, tests, maintenance;
  • proofs for rendering and performance;
  • rebase only;
  • no closing keyword in commits;
  • fork CI;
  • features on all three systems.
• rules/03-review.md: review rules the maintainer has applied after green CI: interface controls, settings without explanatory text, translation keys, performance numbers, PRs that interact.
• rules/04-github.md: how the agents write here, finish a contributor's PR, and approve a fork's CI.
• locks.json, what Rusuban's server enforces without the model:
  • supply-chain paths never merge alone;
  • 300 lines and 15 files at most, outside tests and docs;
  • the capture, preview, compositor and export zones need a proof;
  • CodeRabbit required;
  • the Nix build and the Discord and bookkeeping workflows do not gate a merge.

A PR that touches .rusuban/ is never merged by Rusuban: a person merges it.

Testing

• locks.json passes Rusuban's validator, and biome check 2.4.12 with this repo's config.
• Its globs were tried on real paths:
  • package.json at any depth and .github/** are locked;
  • *.test.* and docs/** are exempt from the size limit;
  • VideoPreview.tsx and crates/compositor/** need a proof.
• The same files are Rusuban's published example (examples/rules/openscreen/).

Walkthrough

The changes add repository rules for agent ownership, issue and contributor handling, PR eligibility, review evidence, merge procedures, and CI checks. The lock configuration defines protected paths, change-size limits, required checks, and evidence requirements for specified paths.

Changes: Repository contribution and merge rules

Layer / File(s)	Summary
Ownership and contributor handling .rusuban/rules/01-autonomy.md, .rusuban/rules/04-github.md	The rules define agent and owner responsibilities, issue handling, contributor ownership, and conditions for approving fork CI.
PR eligibility and change limits .rusuban/locks.json, .rusuban/rules/02-merging.md	The lock configuration and merge rules define eligible PR categories, protected paths, change-size limits, required checks, and exemptions.
Review evidence and validation .rusuban/rules/02-merging.md, .rusuban/rules/03-review.md	The rules specify interface and translation checks, performance and rendering evidence, worker-fix requirements, shared-function coordination, and cross-platform expectations.
Merge and CI procedures .rusuban/rules/02-merging.md	The rules define rebase-only merging, commit-message handling, shared-file prioritization, and CI verification.

Estimated code review effort: 2 (Simple) | ~12 minutes

Change: Other

Merge Risk: Minimal · up to 5503e

The contribution and merge rules introduce no established blocking defect. Comparing preview and export across an effect’s full duration remains an optional coverage improvement.

Full details: Title check

Explanation

The title names the main change: adding the Rusuban rules and locks under .rusuban/. The changeset adds .rusuban/locks.json and four rule documents, so the title matches the primary change. The title uses the conventional commit prefix chore:, which fits a configuration-only change.

Full details: Description check

Explanation

The description follows the repository template in structure. It has Summary, Related issue, Type of change, Release impact, Desktop impact, Screenshots / video, and Testing sections. The Summary describes the added .rusuban/ rules and locks.json in detail. Related issue is marked None, which is acceptable for this PR. Type, release, and platform checkboxes are filled in with reasons. Screenshots says no app change, and Testing lists the validator, Biome check, and glob checks. The template's Fixes # line was replaced with None, which is a minor deviation but still clear.

Full details: Docstring Coverage

Explanation

No eligible functions found in the changed files. Skipping docstring coverage check. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 0 functions across 0 files. (1 skipped: 1 unsupported.)

Review comments at @.rusuban/locks.json:
- Around line 36-45: Add the Linux capture bridge to the evidence path patterns
in the `paths` list, ensuring changes to `linuxNativeCaptureSession.ts` require
proof even when `pr.evidence.needed` is omitted. Preserve the existing path
patterns.
- Line 18: Update the Rusuban exclusion rules alongside the "*.test.*" pattern
to also exclude "*.spec.*" files from size limits, so changes to src/*.spec.ts
do not count toward the 300-line threshold.

Review comments at @.rusuban/rules/01-autonomy.md:
- Around line 40-41: Update the contributor PR autonomy rule to define a
fallback and escalation path when maintainer access is unavailable or maintainer
edits are disabled: permit a worker branch and separate PR when needed, while
preserving contributor credit and keeping the original PR open.

Review comments at @.rusuban/rules/02-merging.md:
- Around line 32-35: Update the merge criteria to require a before-and-after
comparison of preview pixels alongside the export and performance checks, and
require updating locks.json to match the verified preview result.

Review comments at @.rusuban/rules/03-review.md:
- Line 46: Update the new-branch and PR instruction to apply only to issue
fixes; for contributor fixes, direct workers to update the contributor’s
existing branch and PR instead of opening a competing PR.

fully resolves the issue, so the issue closes when that PR merges. Keep the
reference non-closing when the replacement is only a partial fix.

that may omit later corrections.

containing untrusted tests on the fork unless repository CI isolates them from

retry when the immediate manual request is skipped due to rate limiting, rather
than enforcing the once-per-head limit; escalate if the delayed retry also
fails, and otherwise continue waiting for the review.

38-39: Trivial · Functional Correctness · Poor tradeoff

Consider comparing the affected effect span.

A single matching frame can miss an effect that disappears early in preview. Comparing the span, including transitions, would improve coverage. Keep locks.json in sync if the proof policy changes.

Update the preview/export proof criterion in the merging guidance to compare the
full affected effect span, including transitions, rather than relying on a
single matching frame. Preserve the existing composition and timing
expectations, and keep locks.json synchronized if this policy change affects it.
