* test(diff): repro for STA-3420 combined-diff invalidation freeze
Co-authored-by: Orca <help@stably.ai>
* Fix diff-view freeze when large diff invalidated by rebase writes
Staged-diff sections now reload in-place on external file changes instead of remounting every visible Monaco editor and bumping the virtualizer generation, which wedged the renderer during rebase bursts.
* test(diff): calibrate STA-3420 burst assertions against an idle baseline
The burst window's peak lag is dominated by a one-off stall from opening 8x15k-line
Monaco editors, which reproduces identically with invalidation disabled. Measure an
equal-length idle window first and assert p95, sample coverage, and lag relative to
that floor. Adds unit coverage for isUnchangedDiffSectionReload.

* fix(diff): keep renderedIndicesRef pure during render
React Doctor blocks ref mutation during render; sync the on-screen
section set in a layout effect instead so static analysis can pass.
* Fix unchanged diff-section reload detection for truncated diffs
When a diff exceeds render limits, content is pruned to '' for memory.
The old check compared content equality, so limited reloads always
appeared changed, triggering unnecessary revalidation that froze the UI.
Compare render-limit metadata instead — it's the sole change signal
and full description of what the fallback banner displays.
Also calibrate STA-3420 e2e assertions relative to idle baseline for
machine independence instead of absolute thresholds.
* fix(diff): defer invalidation reloads for in-flight stale-token loads
When a diff section is invalidated while a large-diff load is in-flight:
- Don't delete the in-flight load from loadingIndicesRef, since a newer load may own it
- Bump the reload token but defer the reload if there's still an in-flight load
- Let the in-flight load settle first, then reschedule the reload at settle-time
- Prevents the freeze by avoiding race conditions that leave sections stuck loading
This fixes STA-3420 where rebase-driven invalidations could hang the diff view.
* test(diff): relax STA-3420 burst assertions to inclusive comparisons
Switch from strict inequality checks (toBeLessThan, toBeGreaterThan) to
inclusive variants (toBeLessThanOrEqual, toBeGreaterThanOrEqual) to allow
measurements landing exactly on the threshold boundaries.

* chore(lint): upgrade oxlint to 1.71 and enable 7 new rules
Upgrade oxlint 1.67.0 -> 1.71.0 (1.72 was blocked by the repo's 3-day
minimum-release-age supply-chain guard; nothing here needs it). The
bump is a no-op on the existing config.
Enable 3 error rules (backlog autofixed to zero in this commit) and
4 warn rules (surface signal without gating CI):
error (autofixed, behavior-preserving):
- unicorn/prefer-node-protocol (~1531 sites: bare builtin -> node:)
- typescript/no-import-type-side-effects (~36: all-inline-type -> import type)
- unicorn/no-array-reverse (19: copy-then-reverse -> toReversed)
warn (real signal, current fires are test-only/correct):
- unicorn/no-array-fill-with-reference-type (aliasing footgun guard)
- typescript/no-unsafe-function-type (bans bare Function type)
- unicorn/prefer-array-flat-map (map().flat() -> flatMap())
- unicorn/prefer-regexp-test (.match() in bool ctx -> .test())
mobile/.oxlintrc.json extends root, so it inherits all 7; the autofix
ran from root and covered mobile/ too.
Verification (all green): oxlint 0 errors (root+mobile+aux configs),
oxfmt clean, typecheck (node+cli+web), vitest 22795 passed / 0 failed,
builds (electron-vite + web + cli) succeed. node: rewrites confirmed to
skip embedded SSH/CLI string payloads (AST-only); all toReversed sites
verified to operate on fresh copies or write-once locals.
* chore(lint): bump mobile oxlint to 1.71 so inherited rules parse
mobile/ is a standalone pnpm project pinning its own oxlint@1.67, which
lacks unicorn/no-array-fill-with-reference-type (needs >=1.70). Since
mobile/.oxlintrc.json extends the root config, mobile CI's 'cd mobile &&
oxlint' failed to parse the new rule. Bump mobile to match root (1.71).
Verified in mobile/: oxlint 0 errors, oxfmt --check clean, tsc --noEmit
pass, vitest 978 passed / 0 failed.

* fix(changes-tab): prevent freeze and stale highlights when staging/unstaging
When files are staged/unstaged while the Changes tab is open, the
diff viewer was re-rendering all sections, causing UI freezes and
highlight flickering.
- Add resolveCombinedUncommittedSnapshotEntries() to reconcile
snapshot entries with live git status without destroying existing
loaded diff content.
- Track retainedResolvedSnapshotEntries from current sections to
preserve area state when live git status temporarily loses entries.
- Use Map-based O(snapshot + live) algorithm instead of nested loops.
- Add unit tests for the resolver logic.
- Add e2e test with performance measurement for stale unstaged diffs.

* Prevent duplicate entries in uncommitted snapshot resolution
Track resolved snapshot entries using composite area and path keys to
ensure staged and unstaged sections remain distinct and do not duplicate
when live Git status changes or disappears.
Additionally, switch the retained entries from a Map to a list to support
multiple areas per path, and update CombinedDiffViewer to avoid rebuilding
the snapshot list on row load state changes.
* test: add test coverage for duplicate-path snapshot remapping
- Add unit test verifying that duplicate-path snapshots do not remap
to a retained fallback area.
- Robustify E2E large diff freeze repro test by ensuring interval
timers are always cleared in a finally block.
- Standardize path utilities in large diff fixtures to ensure cross-platform
compatibility.
