## Stack Layer 3 of the replacement stack for microsoft#2940. - Base: `main` (microsoft#2966 and microsoft#2967 are merged) - Parent layer: microsoft#2967 (merged) ## Included - Persists headless Markdown updates directly to the authorized workspace file. - Makes streaming completion idempotent by recognizing the already-produced revision instead of applying operations twice. - Carries immutable binding identity and SHA-256 revision checks across read/apply. - Rejects stale tokens, rebound root/path/file identities, revision conflicts, and roots replaced by symlinks or junctions. - Adds request IDs to concurrent document read/apply IPC and correlates responses. - Keeps the view service server-authoritative for update persistence even when no browser/SSE client is connected. ## Deferred to browser layer - Browser `document-manager.ts` rewrite and serializer/autosave behavior. - Primary/secondary SSE lifecycle, browser synchronization/promotion UX, and reopening the same file while preserving browser binding state. - Broader browser snapshot adoption and loopback binding behavior. ## Validation Historical results from before the rebase (not rerun as full build/Jest validation): - `@typeagent/markdown-agent` TypeScript and frontend build - Focused Jest suites: 44 tests passed across Markdown persistence, operation engine, path policy, creation path policy, and action handler coverage - Prettier changed-file check - Git diff check - Repo lint ratchet After rebasing onto `f3e4308ea2cd722a2905eceac3f2a1e61d19a420`: 23 focused Node integration smoke checks passed using the actual handler, persistence module, and operation engine with simulated translator/view IPC; TypeScript 5.4.5 syntax parsing and Git diff checks passed. Full build/Jest, semantic typechecking, and repository ratchets were not rerun: this worktree has no installed dependencies (`fluid-build` missing). Pinned Prettier 3.5.3 was unavailable offline. Complete layer diff against the new main base: 992 insertions, 532 deletions (1,524 changed lines), across 6 files. --------- Co-authored-by: Copilot App <223556219+Copilot@users.noreply.github.com>
