feat(session): add turn diff route

GET /api/session/:sessionID/diff?messageID&to&context returns FileDiff.Info[] for the turn containing a user message (default: the newest one), or the contiguous range through a later user message's turn. A turn runs from the first prompt after the Session was last idle until its idle marker, so steers belong to the turn they interrupted; Sessions without markers fall back to prompt-to-next-prompt. The diff compares the range's first recorded step snapshot with its last recorded one, or with the working copy only while the Session is actively executing, resolves the snapshot repository from the Location in effect at the range (rejecting ranges that span a move), and defaults to full-file patches like vcs.diff. Shared missingMessage and failedSnapshot handler helpers replace the inlined mappings in the session handlers.

@@ -108,3 +108,28 @@ Storage-key relocation (`previousKey`, workspace aliases, draft storage moves)
 remains separate from schema migration. Draft blob externalization and hydration
 also remain in the storage adapter: composer codecs receive hydrated references,
 not raw ID-only blob documents.
+
+## Large draft content
+
+Draft documents never carry large text inline. Any string of `draftTextThreshold`
+characters or more is split into `draftTextChunk`-sized content-addressed blobs and
+stored as `{ blob: { kind: "text", ids: [...] } }`; reads join the chunks again. A
+content-keyed cache means unchanged chunks are not hashed or sent on later saves, so
+typing after a large paste uploads one chunk per save rather than the paste. Chunk
+boundaries never split a surrogate pair, and a failed upload is evicted so the next save
+retries it.
+
+Blob collection is made safe by validation on write, not by timing. A strict document write
+is refused while it references blob ids the store does not hold, so the previous document
+stays visible; the renderer uploads the missing bytes again from the chunk text or the image
+`Blob` it still holds, renames the references to the ids the uploads returned (content hashes
+normally, fresh ids on a store without WebCrypto), and publishes. This covers a chunk another
+tab collected, and an image the composer kept in its history long after its blob was
+collected. The desktop host additionally refreshes `touched_at` for every blob a written
+document references and collects only blobs unreferenced and untouched for `blobGrace`, so
+repairs stay rare.
+`persisted()` hands the draft store the encoded document (`setDocument`) rather than
+a serialized string, so the store does not re-parse the full document to externalize
+it. Both blob collectors (desktop SQL, browser IndexedDB) keep chunk ids alive. This
+follows VS Code's rule that editor content lives in per-resource backups, not in the
+state database.

Shoubhit Dash	cc5086d127	feat(session): add turn diff route GET /api/session/:sessionID/diff?messageID&to&context returns FileDiff.Info[] for the turn containing a user message (default: the newest one), or the contiguous range through a later user message's turn. A turn runs from the first prompt after the Session was last idle until its idle marker, so steers belong to the turn they interrupted; Sessions without markers fall back to prompt-to-next-prompt. The diff compares the range's first recorded step snapshot with its last recorded one, or with the working copy only while the Session is actively executing, resolves the snapshot repository from the Location in effect at the range (rejecting ranges that span a move), and defaults to full-file patches like vcs.diff. Shared missingMessage and failedSnapshot handler helpers replace the inlined mappings in the session handlers.	2026-09-07 22:08:19 +05:30
Shoubhit Dash	b20482461c	feat(session): record idle boundaries as messages Project an idle message when a busy period ends (execution succeeded, failed, or interrupted for any reason other than shutdown, which resumes the same turn). Every step since the previous marker is one turn, including prompts steered in while the Session was busy, so turns are derivable from session_message alone without persisting events or a separate table. The marker is invisible to the model and to the TUI and web transcripts.	2026-09-07 22:00:36 +05:30
Shoubhit Dash	5b5368fe98	perf(core): batch snapshot tree diffs Git.tree.diff ran --name-status, --numstat, and a patch once per changed file, sequentially, so a turn or revert touching N files cost 1 + 3N git processes (~50ms per file). Run the three once over the tree pair, split the patch with VcsPatch.chunksByFile, cap patch output at MAX_TOTAL_PATCH_BYTES like VCS diffs (capped files get an empty patch, stats stay exact), keep core.quotepath=false so non-ASCII paths still match their chunk, and pass --no-ext-diff. Snapshot.diff diffs first and filters ignored paths from the result instead of listing changed files twice and passing every path as a pathspec.	2026-09-07 21:53:19 +05:30
