-Upstream [test262](https://github.com/tc39/test262) files, vendored byte-for-byte and run verbatim by
-`test/test262.test.ts`. Licensed under `test/LICENSE.test262`.
-
-## Layout
-
- `manifest.json` — the pinned upstream revision, which upstream directories are vendored, and what is left out.
- `built-ins/`, `language/` — the vendored files, mirroring upstream `test/`.
- `skipped.txt` — vendored files that fail on a known interpreter gap, one `path  # reason` per line. They are
-  skipped, and each gap is listed as unchecked in `interpreter-support.md`.
- `run.ts` — runs one file: prepends `"use strict"`, provides the harness (`assert`, `Test262Error`,
-  `compareArray`, `$DONE`, `$DONOTEVALUATE`) as host globals, and interprets the file's frontmatter (`negative`,
-  `flags: [async]`).
-
-## What is not vendored
-
-`script/sync-test262.ts` skips a file when its frontmatter declares a `flags`, `features`, or `includes` value the
-manifest marks unsupported, or when its code matches one of the manifest's `boundaries` patterns. Boundaries are
-intentional limits of the interpreter, not compatibility work: classes, `this`, `arguments`, prototype objects,
-property descriptors, accessors, boxed primitives, sloppy mode, `eval`, `Symbol()`, and the `$262` host API. If one
-of those decisions changes, delete its entry and re-sync; the tests are upstream, not lost.
-
-## Commands
-
-```sh
-bun run script/sync-test262.ts /path/to/test262   # re-copy at the pinned revision; edit manifest.json to change scope
-bun run script/test262-report.ts [--write] [dir]  # run everything, group failures by cause; --write regenerates skipped.txt
-bun test test/test262.test.ts                     # what CI runs
-```
-
-When a fix makes skipped files pass, the report lists them so they can be removed from `skipped.txt`, and the
-matching gap in `interpreter-support.md` is checked in the same change.

Shoubhit Dash	54504ab3a5	fix(client): synthesize idle messages live The solid data layer mirrors every projected marker message from its event so the in-memory transcript matches the server before the next read; do the same for the idle marker on execution succeeded, failed, and non-shutdown interrupted.	2026-09-07 23:57:17 +05:30
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
