* feat(protocol): define streamed diff revisions and resolve tag bases
* feat(server): stream shared diff revisions with paced file bodies
* feat(client): observe streamed diffs with atomic revision updates
* feat(app): show the Changes tree while diff bodies stream
* fix(server): retain the legacy structured diff payload budget
* fix(diff): preserve revision ordering and readable files
* fix(diff): select renamed patches and read dangling symlinks
* fix(diff): preserve nested checkouts and ambiguous patch paths
Only regular files and symlinks are readable untracked entries. Prefer patch metadata to ambiguous unquoted headers so paths containing a prefix delimiter keep their hunks.
* fix(diff): preserve BOM text and complete file replacements
Decode each string without consuming its leading BOM. File-type replacements emit multiple patch sections for one listed path, so retain all matching hunks. Assert the optional rename metadata in the existing commit-file journey.
* fix(diff): highlight symlinks from their stored target text
Working tree source context must match the symlink blob emitted by Git rather than the contents reached by following the link. Otherwise highlight runs do not cover the patch line and encoding fails the revision.
* fix(diff): tolerate disappearing highlight sources
Source context is optional after Git has produced the patch. Missing worktree link metadata must preserve the existing hunk-based highlighting fallback instead of failing the revision.
* fix(diff): batch cold reads and refresh logical comparison inputs
Acquire bounded pages of tracked patches lazily after Begin while retaining per-file highlighting and awaited frame delivery. Keep legacy preferred-base selection live across revisions and include submodule Git state in worktree cache identity.
* fix(diff): distinguish gitlink directories from replacements
A raw old gitlink mode also occurs when a submodule becomes a regular file. Query nested Git state only for a current directory, preserving normal file identity for replacements.
* fix(diff): invalidate timestamp-preserving file replacements
Size and modification time do not identify live file contents after a preserving copy. Include filesystem change time and file identity for tracked and untracked reuse, and verify live revisions agree with fresh reads.
* fix(diff): align highlight tokens with normalized patch lines
Git can normalize CRLF worktrees while highlighting reads their original line endings. Match tokens to the emitted patch text and trim only a normalization CR before encoding runs; mismatched source tokens are not attached.
* fix(diff): refresh equivalent worktree paths across platforms
Explicit refreshes must match filesystem-equivalent roots, including Windows path aliases. Use the existing realpath-aware matcher, budget real Git completion waits consistently, and assert optional status metadata in the filesystem commit-file journey.
* fix(diff): validate Git inputs and resolve refresh roots
Reuse now accounts for effective attributes, configuration, and canonical worktree blobs as well as filesystem state. Explicit refresh resolves repository identity like subscription creation, and callers await that resolution before acknowledging the command.
* fix(diff): keep non-Git workspace refresh successful
Diff invalidation has no target repository for an ordinary folder. Treat that expected absence as a no-op while preserving other root-resolution errors.
* fix(diff): observe scoped Git interpretation settings
Classify each metadata root with its worktree and common scopes, retaining both when the directories coincide. Shared attributes affect all checkouts, while config.worktree belongs to the owning checkout. Real subscriptions verify automatic binary and hunk-context refreshes in main and linked worktrees.
* fix(diff): observe interpretation inputs for pinned comparisons
Immutable commit objects still depend on mutable Git configuration and attributes. Declare those metadata inputs independently of ref, index, and worktree mutability, while keeping unrelated endpoint events out of pinned comparisons.
* fix(diff): observe interpretation independently of comparison endpoints
Commit comparisons still read worktree attributes. Watch those inputs independently, checking effective Git interpretation before invalidating fixed contents. Retain paths hidden by whitespace filtering so attribute changes can expose them. Forward binary frames through the branch-loading test interceptor.
* fix(server): keep diff highlighting responsive and bounded
Tiny patches previously parsed both full source versions synchronously. Yield between parser work units and admit source by UTF-8 bytes, keeping large patches renderable without tokens. Cancel obsolete highlighting when a newer diff supersedes it.
* fix(server): keep diff cancellation with its requester
Independent commit viewers must not cancel each other. Use request-source cancellation for commit highlighting and cache invalidation for checkout highlighting. Oversized source versions use the existing budgeted hunk reconstruction so large lockfiles retain useful syntax tokens.
* feat(git): default review to all branch changes
Keep the selected comparison stable while agents edit and commit so reviewing the complete result does not require switching scopes or interrupt unfinished comments.
* test(git): release Windows checkout handles during cleanup
Allow transient filesystem handles from subscription teardown to close before removing the test repository.
* fix(git): return checkout diff hunks from subdirectory workspaces
Checkout paths are repository-relative, but one-shot diff reads used the workspace subdirectory for Git pathspecs. Resolve the worktree root once so patch selection and file reads use the same coordinates as the live subscription.
* test(server): await bounded discard fixture cleanup on Windows
The discard assertions pass but Windows can retain a directory lock during cleanup. Await asynchronous removal with bounded retries after daemon shutdown, preserving failure for persistent locks. Matches the verified cleanup correction in #6912 for #6918.

Hunk content resembling patch headers was discarded before line parsing. Metadata is already ignored before the first hunk, so preserve every added and removed line once a hunk starts.
Closes#6564
