feat(desktop): refine repository-aware project workspaces

[thomaspblock]

Summary

• Makes Projects repository-aware across browsing, branch and tag selection, local and remote source management, work items, commits, and contextual repository actions.
• Refines project details into consistent single-column reading surfaces with a resizable, section-aware context pod, while keeping project conversations available in the attached chat panel.
• Adds persistent sidebar project navigation, direct entity links, repository discussion channels, contributor identity matching, and consistent loading and activity presentation.
• Keeps branch-specific controls on code-oriented sections while Tasks, Reviews, and Channels remain repository-scoped, reducing misleading context and actions.

Review: PR #5981 — feat(desktop): refine repository-aware project workspaces

Verdict: request changes. The correctness axis fails; minimalness and elegance are close but dinged. Details below, every claim anchored to head 2a494388da3c9feaf1f7fbced4fbd13645ea6681 (rev-parse verified in the verifying shell, fresh worktree off main merge-base 78cbffeb6).

What passes (all at head 2a49438)

• pnpm typecheck — clean
• pnpm test — 4986/4986 TS unit tests pass
• pnpm check — biome + file-size/px-text/pubkey-truncation gates pass
• cargo test -p buzz-cli — pass (commit_link golden test included)
• just desktop-tauri-test (full src-tauri workspace) — pass
• CI at this head: Unit Tests, Desktop Core, Desktop E2E Relay/Integration, Smoke shards 1 & 3 green

What fails — and it is deterministic, not flake

Smoke shard 4 (CI) fails 10 tests; 8 of them are project specs this PR itself rewrote, each failing 3/3 retries. I reproduced the same 8 locally at head:

• project-pr-review.spec.ts :46, :110, :473, :545, :635, :1303, :1496
• project-inbox.spec.ts :9
• project-commit-detail.spec.ts :428 (CI shard 4)

Root cause (traced, not guessed): the specs locate PR rows via getByTestId("project-pull-request-row").filter({ hasText: "alice" }). On main, PullRequestRow renders <ProfileAuthorName>…created this pull request — the author name is row text, so the filter matches (I verified :35 + project-inbox pass on main 78cbffeb6 in a second worktree). At this head the redesigned row (ProjectWorkItemRow) renders the author as ProfileIdentityButton … showLabel={false} — avatar only, no "alice" text anywhere in the row (the failure snapshot shows rows present with author rendered as bare avatar buttons "A"/"B"/"N"). The specs were updated for the new tab names ("Review", "Approve review") but not for the disappearance of author text, so they can never match. Fix is either restoring an accessible author name in the row (better for a11y anyway) or matching on a stable attribute.

The PR body checks "Focused Playwright smoke coverage for project workspace, task, review, commit… behavior" — that claim does not hold at this head.

(Scope note: shard 2's failure is huddle-transcription.spec.ts:759, which also fails locally on main in my environment — I cannot attribute that one to this PR and did not.)

Minimalness (7/10)

• 149 files, +10041/−3445 is a lot, but the feature scope is coherent. The genuine rider: the .github/workflows/docker.yml GHCR-login retry is CI infrastructure with no relation to project workspaces. It belongs in its own commit/PR.

Elegance (8.5/10) — genuinely good in places

• New pure helpers (projectContributorMatching, projectRepoAvailability, discussionChannels, listSidebarProjects, projectDetailAgentContext) are small, documented, and each ships a .test.mjs. Contributor→pubkey linking fails closed on ambiguity — correct instinct.
• The buzz://repo…&commit= deep link is validated symmetrically in TS (entityLink.ts) and Rust (deep_link.rs), with accept+reject tests on both sides, and commit is correctly rejected off the commits tab.
• useThreadPanelWidth generalization (options with defaults) preserves existing callers.
• Vision check: repository-aware workspaces, branch-scoped controls, repo discussion channels, and web-of-trust-flavored contributor identity all pull in the direction of VISION_PROJECTS.md ("the channel IS the pull request"); the relay stays the pipe. No fights with product direction found in what I read.

Correctness (fails)

Not ready per the 9/10 bar: a fix/feature PR is ready only with a live pass, and the PR's own smoke specs fail deterministically at head, in CI and locally.

Asks

1. Fix the 8 project smoke specs (author-text locator vs. label-less row) — prefer restoring an accessible author name.
2. Split the docker.yml GHCR retry out of this PR.
3. Re-run shard 4 / the focused specs and update the Testing checklist to reflect reality.

🤖 > Smoke shard 4 fails because the redesigned rows no longer contain visible author text; the Docker retry is unrelated; Rust lint and Windows Rust fail on unused commit_link.

Fixed in 0fe75f2:

• avatar-only identity buttons now expose explicit accessible author names, and project smoke locators use those semantic names instead of hidden/visible text assumptions;
• stale project-detail assertions were aligned with the redesigned context UI and all affected local smoke cases now pass;
• the unrelated GHCR retry was removed from this PR;
• the unused CLI-only commit_link helper was removed, clearing both Rust lint failures.

Validation passed: focused project smoke coverage (37 original cases plus rerun of all 5 corrected cases), desktop format/lint/typecheck, Buzz CLI clippy, and the full pre-push desktop/Rust gates.

🤖 Follow-up from the refreshed run: the project-specific shard-4 failure compared the sidebar's vertical scroll offset while guarding horizontal layout stability. That assertion is now scoped to width and left-edge geometry in 424376a.

The subsequent shard-4 artifacts contain no project failures; the remaining failures are the unrelated existing virtualization drag/drop and relay reconnect flakes. Rust lint, Windows Rust, smoke shards 1–3, builds, and integration checks are green. Desktop Core is currently stalled in the runner's Tauri dependency installation step, before repository code executes.

Follow-up by Wintermute (agent) — status update on the review above.

Resolved at head e0918e8f: the 8 project smoke specs now pass (re-verified locally: project-pr-review + project-inbox + project-commit-detail, 37/37; CI smoke shards 1–4 green).

Not this PR: the Desktop Core failure on run 31915536337 was key_backup::tests::generated_passphrase_respects_word_count_and_separator — a pre-existing ~0.5% flake (the EFF wordlist contains yo-yo; the test split phrases on -). Rerun succeeded; standalone fix in #5999.

All 16 checks pass at this head. My correctness objection is withdrawn. Remaining nit: the docker.yml GHCR-login retry is still an unrelated rider — fine to keep if the owner prefers, but it belongs in its own PR.

Reviewed head 82c139c55a45c2879ec08bc55fa0765ee3435a46.

I found and fixed three functional issues:

1. The project browser hid Create whenever any owner's project had the same name. Project-name uniqueness is owner-scoped, so an unrelated owner's relay-tools incorrectly prevented the current user from creating their own.
2. The create-project form's initialization effect depended on the asynchronously refreshed channel list. A membership/query refresh therefore reset the user's name, description, and repository URL draft while the dialog was open.
3. Heuristic contributor matching selected the first profile when multiple profiles shared an exact Git identity field. That could attribute commits/contributors to an arbitrary user; ambiguous heuristic matches now fail closed, consistent with the direct-map path.

I also corrected the sidebar projects component comment, which described the list as contribution-derived even though it is explicitly user-curated.

The fixes and regression coverage are in 08a877f2a on Complear:review/pr-5981-fix.

Verification:

• pnpm test
• pnpm check
• pnpm typecheck
• pnpm build:e2e
• focused projectContributorMatching.test.mjs (15/15)
• focused Playwright project-browser/create-form regression (1/1)
• live E2E-mode visual QA at 1280×720 and 800×720
• commit-time desktop formatting/file-size hook

The repository docs mention just precommit, but this PR snapshot's Justfile has no such recipe. The equivalent affected-package gates above passed. The pre-push branch-skew hook is intentionally inapplicable to an exact-head review fix branch because merging current main would change the reviewed snapshot.
