Merge branch 'main' into pat/polly-add-cursor-hermes

docs(cursor-native): note idle block runs outside the store-gated branch

-# Reviewer routing map -- area -> candidate reviewers.

-# This is NOT a GitHub CODEOWNERS file. It deliberately lives at .github/reviewers
-# (a non-magic path) so GitHub's native CODEOWNERS feature does NOT auto-request
-# reviewers. All assignment is driven by .github/workflows/auto-assign-reviewer.yml,
-# which:
-#   - runs ONLY on fork PRs authored by a non-maintainer, and
-#   - assigns EXACTLY 1 load-balanced reviewer from the area(s) the PR touches
-#     (falling back to the full set of handles in this file for unowned paths).
-# So the per-area lists below are the CANDIDATE pool per area, not "everyone gets
-# requested". This is routing only -- it does not gate merge (that stays
-# Maintainer Approval + Merge Ready).
-#
-# Syntax is CODEOWNERS-like for familiarity: "<path-prefix>  @handle @handle".
-# Last matching line wins per file. Owners must be maintainers in
-# .github/MAINTAINER. Per-area owners are the top maintainers by COMBINED commit
-# count across both repos (databricks-eng/agent-framework full history +
-# omnigent-ai/omnigent), up to ~4 per area, excluding tree-wide mechanical
-# sweeps (>100 files) and non-maintainer contributors. Worth a periodic
-# sanity-check.

+# Harness Plugin Interface
+
+Omnigent now discovers optional harness support through Python entry points.
+Core `omnigent` ships the built-in harness contribution. A separate package, for
+example `omnigent-kimi`, can add harness ids, aliases, runner modules, install
+metadata, model environment plumbing, and picker labels without adding that
+harness to the default install.
+
+The goal is:
+
+- `pip install omnigent` gives only core harnesses.
+- `pip install omnigent-kimi` adds Kimi support to the same `omni` CLI and
+  server process.
+- Core can still produce a targeted error for known optional harness ids:
+  install `omnigent-kimi`.
+
+## Package Contract
+
+An optional harness package declares an entry point in the
+`omnigent.community.harnesses` group. Community harness implementation modules
+must also live under the `omnigent.community.harnesses.*` namespace; core rejects
+plugins that try to register flat packages or override builtin harness names.
+
+```toml
+[project]
+name = "omnigent-foo"
+dependencies = [
+  "omnigent==0.3.0.dev0",
+]
+
+[project.entry-points."omnigent.community.harnesses"]
+foo = "omnigent.community.harnesses.foo.plugin:get_contribution"
+```
+
+For local sibling checkouts, keep the package dependency normal and point uv at
+the local core checkout:
+
+```toml
+[tool.uv.sources]
+omnigent = { path = "../omnigent-oss-2", editable = true }
+```
+
+If the plugin lives inside the core repo, the relative path should point back to
+the repo root. If it moves to a sibling repo, update the path. A bad path is why
+uv may try to build `omnigent @ file:///Users/<user>`.
+
+## Registry Types
+
+The public interface lives in `omnigent.harness_plugins`:
+
+```python
+from omnigent.harness_plugins import HarnessContribution
+from omnigent.harness_install_spec import HarnessInstallSpec
+```
+
+`HarnessInstallSpec` intentionally lives outside `omnigent.onboarding` so a
+plugin can be imported during entry-point discovery without pulling in the
+provider/onboarding stack and creating import cycles.
+
+### `HarnessContribution`
+
+Each plugin exports a `get_contribution()` function returning
+`HarnessContribution`.
+
+```python
+def get_contribution() -> HarnessContribution:
+    return HarnessContribution(
+        name="omnigent-foo",
+        valid_harnesses=frozenset({"foo"}),
+        harness_modules={
+            "foo": "omnigent.community.harnesses.foo.inner.foo_harness",
+        },
+        aliases={
+            "foo-code": "foo",
+        },
+        install_specs={
+            "foo": HarnessInstallSpec(
+                "Foo",
+                "foo",
+                package=None,
+                install_hint="curl -fsSL https://foo.example/install.sh | bash",
+                login_args=("login",),
+                logout_args=("logout",),
+            ),
+        },
+        harness_install_keys={
+            "foo": "foo",
+            "foo-code": "foo",
+        },
+        missing_install_package={
+            "foo": "omnigent-foo",
+            "foo-code": "omnigent-foo",
+        },
+        harness_labels={"foo": "Foo"},
+    )
+```
+
+## Field Semantics
+
+`valid_harnesses`
+: Canonical harness ids accepted by spec validation once the plugin is
+installed.
+
+`harness_modules`
+: Maps each canonical harness id to the subprocess module that creates the
+harness app. `omnigent.runtime.harnesses` merges these into `_HARNESS_MODULES`.
+
+`aliases`
+: User-facing spellings canonicalized by `omnigent.harness_aliases`, for example
+`foo-code -> foo`.
+
+`install_specs`
+: Plugin-provided CLI install/auth metadata, keyed by install key. Use
+`HarnessInstallSpec` from `omnigent.harness_install_spec`.
+
+`harness_install_keys`
+: Maps harness ids and aliases to an `install_specs` key. Readiness and
+preflight checks use this to decide which CLI binary a harness requires.
+
+`model_env_keys`
+: Maps harness id to an env var name used by launcher/spec generation for model
+override plumbing.
+
+`spawn_env_builders`
+: Maps headless harness id to a callable import path. The runner calls this to
+build per-spawn environment variables from the agent spec.
+
+`missing_install_package`
+: Maps known optional harness spellings to the package that provides them. Core
+uses this even when the plugin is not installed so validation and process-manager
+errors can say `pip install omnigent-foo`.
+
+`harness_labels`
+: Maps canonical harness ids to display labels returned by `GET /v1/harnesses`
+and merged into web picker surfaces.
+
+## Runtime Flow
+
+1. Python loads installed entry points in `omnigent.community.harnesses`.
+2. `omnigent.harness_plugins.plugin_state()` merges the built-in contribution
+   with each plugin contribution.
+3. Spec validation checks `accepted_harnesses()` and uses
+   `missing_install_package()` for known optional harness hints.
+4. `omnigent.runtime.harnesses` registers `harness_modules()`.
+5. Runner launch paths consult `spawn_env_builders()` for contributed headless
+   harnesses.
+6. Host readiness uses `harness_install_keys()` and `install_specs()` to gate
+   CLI-backed contributed harnesses on their binary.
+7. The server exposes `GET /v1/harnesses` from `harness_catalog()`.
+8. The web UI merges `/v1/harnesses` into harness picker surfaces.
+
+## Minimal Headless Harness Checklist
+
+For a non-native harness:
+
+- Create a separate package, for example `omnigent-foo`.
+- Add the `omnigent.community.harnesses` entry point.
+- Implement `get_contribution()`.
+- Fill `valid_harnesses`, `harness_modules`, and `aliases`.
+- Add `install_specs` and `harness_install_keys` if the harness needs a CLI.
+- Add `spawn_env_builders` if the harness needs spec-derived env vars.
+- Add `missing_install_package` entries in core if the harness id should produce
+  a targeted install hint before the plugin is installed.
+- Move harness implementation modules into the plugin package.
+- Remove the harness id and module from the built-in contribution.
+
+## Native TUI Harnesses
+
+Community native terminal harnesses are not supported by this interface yet.
+Core native harnesses still use internal registry metadata, but the runner,
+chat-resume, CLI-command, interrupt/stop, and built-in agent seeding paths are
+not pluggable. Community plugins that set `native_harnesses` or `native_agents`
+are rejected at load time until those lifecycle hooks are wired end to end.
+
+## Import Rules
+
+Entry-point loading happens early and can happen while other core modules are
+still initializing. Plugin `plugin.py` should keep top-level imports light:
+
+- safe: `omnigent.harness_plugins`, `omnigent.harness_install_spec`, constants,
+  stdlib;
+- risky: `omnigent.onboarding.*`, `omnigent.cli`, server modules, runner modules,
+  or anything that imports `omnigent.harness_aliases`.
+
+Put heavy imports inside the callable that needs them. For example, a spawn-env
+builder may import provider/runtime helpers inside `build_spawn_env()`, but
+`get_contribution()` should not need onboarding.
+
+## Local Demo Commands
+
+Sibling checkout demo:
+
+```bash
+cd /path/to/omnigent-oss-2
+uv pip install -e .
+uv pip install -e ../omnigent-foo
+
+uv run python -c "from omnigent.harness_plugins import valid_harnesses; print('foo' in valid_harnesses())"
+uv run python -c "from omnigent.runtime.harnesses import _HARNESS_MODULES; print(_HARNESS_MODULES['foo'])"
+```
+
+If the plugin dependency still points at a published or wrong local `omnigent`,
+use the sibling source override in the plugin `pyproject.toml`:
+
+```toml
+[tool.uv.sources]
+omnigent = { path = "../omnigent-oss-2", editable = true }
+```
+
+For published packages, remove local source overrides and publish both
+distributions with compatible versions.
+
+## Tests To Add For Each Split Harness
+
+- Core registry excludes the optional harness by default.
+- Core validation/error messages suggest the optional package.
+- Installing or faking the entry point adds `valid_harnesses`, aliases, install
+  specs, and harness modules.
+- Readiness/setup tests isolate core-only behavior by stubbing entry-point
+  discovery when the optional package is installed in the dev environment.
+- Two community plugins cannot claim the same harness spelling, alias, or
+  install key.

+# Publishing the Omnigent VS Code extension
+
+This directory holds the Omnigent VS Code extension. It is published
+under the shared **`databricks`** VS Code Marketplace publisher (and the
+`databricks` Open VSX namespace), which means releases flow through the
+Databricks security-hardened release path — direct publishing from this repo is
+blocked by policy.
+
+The work splits into two halves:
+
+- **This repo** builds a SHA256-verified `.vsix` and attaches it to a GitHub
+release. No marketplace tokens live here.
+- **The secure-release repo**
+([`databricks/secure-public-registry-releases-eng`](https://github.com/databricks/secure-public-registry-releases-eng))
+downloads that `.vsix`, verifies the checksum, scans it (`databricks/gh-action-scan`),
+and publishes to the VS Code Marketplace and Open VSX. It holds the tokens and
+the approval gate.
+
+Two existing workflows in the secure repo are the reference:
+[`databricks-vscode.yml`](https://github.com/databricks/secure-public-registry-releases-eng/blob/main/.github/workflows/databricks-vscode.yml)
+(the extension publish flow to adapt) and
+[`omnigent.yml`](https://github.com/databricks/secure-public-registry-releases-eng/blob/main/.github/workflows/omnigent.yml)
+(omnigent's PyPI release, which already checks out `omnigent-ai/omnigent`
+cross-org). Both require SAML SSO to view.
+
+## Steps to release
+
+No tags are pushed by hand — the version flows from a reviewed PR into the
+`.vsix` and the release tag, so they can't diverge.
+
+1. **Open the release PR.** Run the **VS Code Extension Release PR** workflow
+   (`vscode-release-pr.yml`) with the target version (e.g. `0.2.0`). It bumps
+   `editors/vscode/package.json`, adds a `CHANGELOG.md` section, and opens a
+   `Release (vscode): v0.2.0` PR. Review and merge it.
+2. **Build the draft release.** Run the **VS Code Extension Release** workflow
+   (`vscode-extension-release.yml`). It reads the version from `package.json`,
+   builds the `.vsix`, attaches it and its `.sha256`, and creates a **draft**
+   `vscode-v<version>` release (a dedicated tag namespace kept separate from the
+   Python release tags `v[0-9]*`).
+3. **Publish the draft.** The workflow leaves the release as a draft: it is not
+   public and the `vscode-v<version>` git tag is not created until you publish.
+   On GitHub, open the repo's **Releases** page, find the draft, confirm the
+   attached `.vsix` + `.sha256` and the notes look right, then click **Publish
+   release**. Publishing creates the tag and makes the release downloadable by
+   the secure-repo workflow.
+4. **Smoke-test the `.vsix` locally.** Download the `.vsix` from the published
+   release and install it into a clean VS Code, then confirm the extension
+   activates and opens a local server:
+
+   ```bash
+   gh release download vscode-v<version> --repo omnigent-ai/omnigent --pattern '*.vsix'
+   code --install-extension omnigent-vscode-<version>.vsix
+   ```
+
+   Reload VS Code, start a local server (`omnigent server`), and run the
+   **Omnigent: Open** command — confirm it opens an editor pane showing the
+   running server's UI (not a blank pane or an error). This catches packaging
+   problems (missing files, a broken bundle) before anything reaches the
+   marketplaces.
+5. **Publish to the marketplaces.** Dispatch `omnigent-vscode.yml` in the
+   secure-release repo (once it exists), pointing at the `vscode-v<version>`
+   tag; run with `dry-run: true` first, then publish for real.
+
+The one-time setup that makes this possible is tracked below.

+
+## Notes for the secure-repo workflow
+
+- `databricks-vscode.yml` downloads the `.vsix` from the release with
+`gh release download -R databricks/databricks-vscode`. The omnigent variant
+must point `-R` at `omnigent-ai/omnigent` and relax the filename check (it
+hard-codes `databricks-*-${VERSION}.vsix`; ours is `omnigent-vscode-*.vsix`).
+- We author `omnigent-vscode.yml` ourselves — it's our own pipeline, not a fork
+of `databricks-vscode.yml`, so we just write it to expect our `vscode-v*`
+tags. `databricks-vscode.yml` is only a structural template; its
+`Validate tag format` step hard-codes `^release-v([0-9]+\.[0-9]+\.[0-9]+)$`,
+which is *their* convention — when copying that step, change the regex to
+match `vscode-v*`. The only thing that must agree is our two ends
+(`vscode-extension-release.yml` and `omnigent-vscode.yml`), and we control
+both.
+- Cross-org fetch from the public `omnigent-ai/omnigent` repo is already an
+accepted pattern — `omnigent.yml` checks out `omnigent-ai/omnigent` for the
+PyPI release. So reading a public omnigent release from the hardened runner is
+not a new blocker.
+- Marketplace publish binds the `databricks-vscode-marketplace` environment and
+reads `VSCE_TOKEN` / `OVSX_PAT`. A new omnigent flow either reuses that
+environment or gets its own (confirm with DECO which, per step 7).

+# Omnigent for VS Code
+
+A minimal VS Code extension that opens your **running local Omnigent server** inside
+the editor — an editor-beside pane that iframes the same UI you see at
+`http://127.0.0.1:6767`. It is a thin client of the local server's existing HTTP API
+(`server/API.md`); there is nothing new to run on the server side.
+
+This is the first, deliberately small donation (tracking
+[omnigent-ai/omnigent#1219](https://github.com/omnigent-ai/omnigent/issues/1219)):
+localhost discovery, the editor iframe pane, and the activity-bar / editor-title icons.
+Sessions, diffs, send-selection, and remote/embedded rendering are intentionally out of
+scope for now.
+
+## How it works
+
+- On activation the extension discovers a locally running server via
+  `~/.omnigent/local_server.pid` and a `/health` probe (or uses `omnigent.serverUrl`
+  when set to a localhost URL).
+- The Omnigent activity-bar view offers an **Open Omnigent** button. The
+  **Omnigent: Open** command (`omnigent.open`) — also on the editor title bar and in the
+  command palette — opens an editor-beside pane that frames the running server.
+- The iframe path is used for **local** servers only; a local server is loopback and
+  needs no auth, so no token ever appears in the iframe URL.
+
+## Settings
+
+| Setting | Default | Purpose |
+|---|---|---|
+| `omnigent.serverUrl` | `""` | Manual **localhost** server URL override (e.g. `http://127.0.0.1:6767`); empty = auto-discover. Non-localhost URLs are not supported in this build. |
+
+## Known limitation
+
+On macOS, VS Code does not deliver `Cmd+A/C/V` keystrokes into a cross-origin iframe
+inside a webview, so keyboard paste into the framed app's inputs does not work there.
+This is an upstream VS Code issue, not fixable from the extension for the iframe render
+path — see microsoft/vscode#129178 and microsoft/vscode#182642. (The on-page copy
+buttons and `navigator.clipboard` paths still work.)
+
+## Build / test / package
+
+```bash
+npm ci
+npm run type-check   # tsc --noEmit
+npm run test         # vitest run
+npm run build        # esbuild -> dist/extension.js
+npm run package      # @vscode/vsce package -> omnigent-vscode-<version>.vsix
+```
+
+Install the resulting `.vsix` via the Extensions view → "Install from VSIX…". The
+`.vsix` runtime is `dist/extension.js` + `media/`.

+    Retries are bounded by ``_PERMISSION_MAX_CONSECUTIVE_FAILURES`` consecutive
+    *hard* failures, classified by kind — NOT by wall-clock. This is the #1782
+    fix: before it the retry deadline was ``_PERMISSION_TIMEOUT_S`` (a day), so
+    a persistently down server re-POSTed — re-driving the turn and respawning
+    harness/tool subprocesses — every ≤30s for 24h.
+
+    Failure classification:
+
+    * **Hard failure → count toward the cap.** A 5xx, or a connection that
+      never established (:data:`_NEVER_CONNECTED_ERRORS`), or an established
+      connection that dropped in under :data:`_PERMISSION_HELD_POLL_FLOOR_S`
+      (a flapping/crash-looping server). This is the spin.
+    * **Held-poll sever → reset the counter.** An established connection that
+      dropped mid-poll after being held ≥ the floor. That is a proxy severing
+      an idle long-poll — the re-park mechanism working as intended — so it
+      must NOT count, or a legitimately-parked human approval behind a
+      severing proxy would be capped after a handful of severs. Classifying by
+      *how the request failed* (established-then-severed vs never-connected),
+      not by elapsed wall-clock, is what makes "a slow human is never capped"
+      hold even when the proxy severs every 30-60s.
+
+    A hard 4xx is final (bad request won't succeed on retry).
+
+    Residual limitation (by design): a *sick* backend behind a proxy/LB that
+    accepts the connection and then silently severs it after its upstream
+    timeout (>= the floor) is indistinguishable at the transport layer from a
+    proxy severing a genuinely-parked human poll — both surface as an
+    established-then-severed error after N seconds, and the server holds the
+    POST silently with no client-visible "parked" ack. So this case resets the
+    counter and is NOT caught by the consecutive-hard-failure cap; it is bounded
+    only by the absolute :data:`_PERMISSION_TIMEOUT_S` ceiling below (the same
+    day-long human-answer window). That is the tightest safe client-side bound:
+    capping it sooner would necessarily cap a real slow human on the same
+    topology. The blast radius is limited — this loop only re-POSTs over HTTP
+    from one hook process (it does not itself respawn harness/tool
+    subprocesses), and the host-side orphan reaper (#1782 Bug A) reclaims any
+    subprocesses a re-driven turn does spawn — so the worst case is one hook
+    slow-retrying for up to a day, not the original zombie pileup.

+loop tails it and POSTs an ``external_session_status: idle`` event — the SAME

+terminal and wake its parent's inbox. Without this a cursor-native sub-agent

+"""Turn-completion ("idle") poster state for the hermes-native harness.
+
+The completion->parent-wake path needs a harness to POST an
+``external_session_status: idle`` event to the Sessions API: the server maps
+that edge to a sub-agent turn-terminal and wakes the parent orchestrator's
+inbox (the SAME contract claude-/codex-/opencode-/cursor-native use). Hermes'
+PTY-activity watcher only emits a ``session.status: idle`` SSE edge that drives
+the web "Working…" spinner and never wakes a parent — so without an explicit
+post a hermes-native sub-agent finishes silently and the orchestrator hangs.
+
+Unlike cursor-agent, hermes-agent exposes NO per-turn ``stop`` hook (only a
+``pre_tool_call`` hook, used for policy enforcement), so there is no separate
+process writing a turn-end marker. Instead the runner-owned
+:func:`omnigent.hermes_native_forwarder.forward_hermes_store_to_session` poll
+loop *derives* turn completion from Hermes' ``state.db`` itself — an
+``assistant`` row with no ``tool_calls`` is the agentic loop's terminal step,
+i.e. one completed turn (see ``_count_completed_turns`` in that module). The
+``messages`` table is the append-only "marker store"; this module owns only the
+*poster* state: how many of those completed turns have already been turned into
+an ``external_session_status: idle`` post.
+
+It is the hermes analog of the poster-state half of
+:mod:`omnigent.cursor_native_status`. Persisting the posted-count means a
+supervisor restart never re-wakes the parent for a turn it already reported.
