-- **Explicit Z.AI compatibility routes.** Independent Z.AI Coding Plan and API login routes now use separate credentials, endpoints, model identities, catalog refresh, logout, and usage/rate-limit state, with immutable compatibility profiles keeping request-format quirks behind the chat-provider boundary.
-- **Streamed tool calls are correlated safely.** Interleaved argument chunks stay attached to their indexed calls, malformed or truncated call streams stop before tool execution, and failed attempts are not retried after output has already been shown.
-- **Deterministic reviewer scopes and supervised tool batches.** Reviewer subagents receive fully resolved Git commit anchors with invalid or empty scopes rejected explicitly, and tool execution runs through a supervised batch engine with ordered results, bounded cancellation, and fail-closed new batches until cleanup drains.
+- **Leaner leaf subagent prompts.** All 12 built-in subagent roles now render a dedicated `system_leaf.md` prompt from shared Jinja partials instead of the full root system prompt, dropping root-only orchestration prose from every spawn (implementer prompt: ~7,270 → ~4,240 words) while keeping the root render byte-identical.
+- **Typed, fail-closed coding-artifact handoff.** The `<coding_artifact>` contract is now rendered and extracted from a single `CodingArtifact` schema — exactly one end-of-message block, duplicate/undeclared keys rejected, and malformed artifacts surfaced distinctly to the judge instead of passing through as valid.
+- **Auto-updates never interrupt a running session.** Updates are downloaded and staged with a verified manifest and applied before the next session (or at clean exit) instead of force-closing the active session mid-run; `auto_update` becomes a policy enum (`off`, `notify`, `download`, `apply_on_exit`) with legacy booleans still accepted, and the post-update smoke check verifies the upgraded binary and version.

+- **Leaf subagent prompt profile.** All 12 built-in subagent roles (implementer,
+  coder, verifier, judge, explore, plan, planner, scout, review, code-reviewer,
+  security-reviewer, debugger) now render a dedicated `system_leaf.md` prompt
+  composed from shared Jinja partials instead of the full root system prompt,
+  dropping root-only orchestration/playbook prose from every spawn (implementer
+  prompt: ~7,270 → ~4,240 words). The root prompt render is byte-identical to
+  before; the shared sections now live once in `agents/default/partials/`.
+- **Typed coding-artifact contract.** `pythinker_code.utils.artifacts` is the
+  single source of truth for the `<coding_artifact>` handoff: the prompt block
+  is rendered from the `CodingArtifact` schema (injected into writer roles via
+  the leaf template), and extraction is strict and fail-closed — exactly one
+  end-of-message block, duplicate and undeclared JSON keys rejected, typed
+  present/missing/malformed results. The `ImplementAndJudge` chain now surfaces
+  malformed artifacts distinctly to the judge and in its result instead of
+  passing them through as if valid, and the verifier's artifact receipt
+  cross-checks `files_changed` against `git diff`.
+- **ImplementAndJudge chain extracted to its own module.**
+  `tools/agent/implement_judge.py` now owns the chain; the full previous import
+  surface of `pythinker_code.tools.agent` is preserved via re-exports.
+- **Post-update smoke check now verifies the upgraded binary and version.** On
+  Homebrew installs the smoke check exercised the still-running old keg via
+  `sys.executable`, so it could report "passed" with the pre-upgrade version;
+  it now targets the brew `opt`-linked launcher and fails (as
+  `VERIFICATION_FAILED`) when the reported version does not match the update
+  target. The persistent "restart to apply" notice is also derived from the
+  recorded update status alone, so dismissing a version's install prompt no
+  longer hides the restart notice after that version is installed.
+- **Updates never interrupt a running session.** On Windows, the background
+  auto-updater previously launched the installer mid-session, force-closing the
+  active Pythinker session. Updates are now downloaded and staged with a verified
+  manifest, surfaced as a "restart to apply" notice, and applied before the next
+  session starts (or at clean exit with the new `apply_on_exit` policy). The
+  `auto_update` config becomes a policy enum — `off`, `notify`, `download`
+  (default), `apply_on_exit` — with legacy booleans still accepted
+  (`true` → `download`, `false` → `notify`); `pythinker info` now reports the
+  mode string, and `/update auto` accepts the new mode names.
