+// Reviewer SLA sweep: nudge + escalate open PRs and issues that a MAINTAINER has

+//
+// Runs on a schedule from the trusted default branch (see review-sla.yml), so it
+// reads no PR-authored code and just talks to the issues/PRs API. For each open,
+// non-draft item:
+//   - PRs: the "assigned person" is any maintainer in requested_reviewers (GitHub
+//     drops them from that list the moment they submit a review, so being in it
+//     means "still owes a review"). The clock starts at their latest
+//     `review_requested` event (fallback: PR opened). If >= SLA_DAYS working days
+//     have elapsed AND they've posted no comment or review since, the SLA is
+//     breached: re-ping them in one comment and add ONE second reviewer (lowest
+//     open-review load among the area owners in .github/areas.json, mirrored as
+//     an assignee like auto-assign-reviewer.js does).
+//   - Issues: the "assigned person" is any maintainer assignee; clock starts at
+//     their latest `assigned` event. Breach -> re-ping + add one second assignee
+//     from the owners of the area(s) whose comp:* label the issue carries.
+//
+// Ownership comes from .github/areas.json -- the single source of truth shared
+// with auto-assign-reviewer.js and issue-triage.yml (it replaced the old
+// .github/reviewers + .github/ISSUE_ASSIGNEES files). `owners_paused` is ignored.

+//   1. a one-shot LABEL, and
+//   2. the MARKER hidden in the reminder comment -- checked as a fallback so that
+//      even if the label write fails after the comment lands, the next sweep still
+//      sees the marker and skips.
+// The second reviewer/assignee is added FIRST (best-effort); the comment is then
+// worded to match what actually happened (so it can't claim "Adding @X" when the
+// add 422'd), and the label is written last. If the comment itself fails nothing
+// user-visible was posted, so we skip the label and let the next sweep retry.

+## Docs staging
+
+Because `main` carries the **next** version, the docs generated from merged PRs
+describe a release that isn't out yet — so they must **not** deploy to the live
+site on merge. Two workflows enforce this by staging onto a **per-minor docs
+branch** on `omnigent-site` instead of `main`:
+
+- **`doc-sync.yml`** — drafts prose docs for each merged PR that needs them.
+- **`sync-openapi-to-site.yml`** — syncs the API reference (`openapi.json`).
+
+Both derive the branch name from `omnigent/version.py` (`0.5.0.dev0` → `0.5-docs`)
+and create it off site `main` the first time a doc PR lands in the cycle. All docs
+for the `0.5` line — including patches — accumulate on `0.5-docs`. Each PR still
+gets its own review, but merging one only lands it on the staging branch, not the
+live site.
+
+At release, publishing the GitHub Release fires `publish-changelog.yml`, which
+opens the **`0.5-docs → main`** PR (see step 5). Merging that publishes the whole
+cycle's docs at once. Nothing to create or retarget by hand — the branch name
+tracks `main`'s version automatically.

+# omnidev
+
+A per-repo dev **pod** supervisor for the Omnigent repo, as a single
+long-running terminal UI. It replaces the three-terminal local dev flow
+(`omnigent server`, `omnigent host`, `npm run dev`) with one process that:
+
+- runs each checkout in an **isolated pod** — its own state dir, database,
+  artifacts, logs, and auto-allocated ports — so multiple worktrees never
+  collide;
+- **supervises** the backend server, the host daemon, and the Vite frontend,
+  restarting any that crash (with backoff);
+- **reloads the backend** (server → host) when you edit `omnigent/**/*.py`;
+  the frontend self-reloads through Vite HMR;
+- gives you **scrollable per-process log panes** plus a combined view.
+
+## Build & run
+
+Requires the repo's usual dev prerequisites (`uv` for Python, `npm` for the
+web UI) plus a Rust toolchain.
+
+```bash
+cd dev/omnidev
+cargo run            # launches the TUI for the surrounding checkout
+```
+
+Run it from anywhere inside the checkout — it walks up to the repo root
+(the `.jj`/`.git` marker) and requires `omnigent/` and
+`web/` to be present. Build a release binary with `cargo build --release`
+(lands at `target/release/omnidev`).
+
+## What it starts
+
+| Process | Command | Notes |
+|---|---|---|
+| server | `uv run omnigent server --host 127.0.0.1 --port <p> --database-uri … --artifact-location …` | Waited on via `GET /health`. |
+| host   | `uv run omnigent host --server http://127.0.0.1:<p>` | Started once the server is healthy. |
+| vite   | `npm run dev -- --port <p> --strictPort` (cwd `web/`) | `OMNIGENT_URL` points its proxy at the pod's server. |
+
+Open the UI at the `ui` URL shown in the header (the Vite dev server).
+
+## Isolation
+
+All Omnigent state is redirected into the pod dir via environment variables —
+the same pattern `scripts/backend-smoke.sh` uses:
+`HOME`, `TMPDIR`, `XDG_*`, `OMNIGENT_CONFIG_HOME`, `OMNIGENT_DATA_DIR`,
+`OMNIGENT_DATABASE_URI`, and `OMNIGENT_URL`.
+
+The pod dir defaults to
+`${XDG_CACHE_HOME:-~/.cache}/omnidev/<repo-name>-<hash>/`, keyed to the
+canonical checkout path. Per-process logs are written through to
+`<pod>/logs/{server,host,vite}.log` for inspection outside the TUI.
+
+## Options
+
+```
+--server-port <N>   Force the backend port (default: probe from 6767)
+--vite-port <N>     Force the Vite port (default: probe from 5173)
+--pod-dir <PATH>    Use a specific pod dir instead of the per-repo default
+--no-vite           Backend + host only (no frontend)
+--clean             Wipe the pod dir before starting

+# Queue + steer design
+
+Client-side message queue with edit / delete / steer / reorder, for both SDK and
+native harnesses.
+
+## 1. Motivation
+
+Today every message is **POSTed the moment the user hits send** — including
+follow-ups typed while the agent is still working — and rendered immediately as an
+optimistic bubble. The runner buffers a mid-turn message behind the active turn
+and delivers it later, but the UI has already committed it. Problems:
+
+- **No edit / delete / reorder.** Once POSTed the message is server-owned, so the
+  user can't take back or fix a follow-up they queued in a hurry.
+- **No queued-vs-sent visibility.** A follow-up sent mid-turn looks identical to a
+  normal send — the user can't tell it's waiting behind the active turn, or when
+  it will be picked up.
+- **Silent cross-harness inconsistency.** The *same* action — "send a follow-up
+  while the agent is working" — behaves differently per harness (mid-turn steer
+  for live-queue SDKs, next-turn for everyone else) with no signal telling the
+  user which they'll get.
+
+The redesign fixes all three by holding the message in a **client-side queue
+before it is POSTed**: the user can edit / delete / reorder while it waits, sees
+it explicitly as "queued", and controls when it's sent (auto-flush on idle, or
+steer now).
+
+## 2. Proposal
+
+Move the queue **client-side**. The strip becomes a pre-POST draft buffer; a
+message is only sent to the server when it's flushed or steered.
+
+```
+   type → client queue "⏱ Queued" (NOT posted) → flush/steer → POST → bubble
+   (strip = "not yet sent, still editable"; bubble = "sent, in flight")
+```
+
+### Queue behavior
+
+- **Show as queued** when the agent is **not idle** (`sessionStatus` busy) — same
+  signal for SDK and native.
+- **Auto-flush head on idle (FIFO):** when the agent goes idle, send the head of
+  the queue as the next turn. Type-ahead "just works" without any click.
+- Persist the queue in `localStorage` (keyed by session) so it survives a hard
+  refresh. (Trade-off: no cross-device sync — acceptable for unsent drafts.)
+
+### Per-message actions
+
+| Action | Behavior |
+|--------|----------|
+| **Edit** | pull the message back into the composer, purely client-side; persists across navigation/refresh |
+| **Delete** | drop the message from the queue |
+| **Steer** | POST it now (jump the queue) — deliver mid-turn where the harness supports it |
+| **Reorder** | client-side drag (grip handle) to reorder the queue within a conversation |
+
+### Promote-to-bubble rule
+
+Promote a message from the strip into a normal chat bubble **as soon as it is
+POSTed** (on flush or steer) — *not* when the agent consumes it. Once it's sent
+there's no longer anything to edit / delete / steer / reorder, so the strip has
+no reason to hold it.
+
+The gap between (a) sent to server and (b) consumed by the agent becomes an
+**implementation detail** the user need not see — because the strip no longer
+represents server state, only the still-editable client buffer. This removes the
+consume-timing dependency entirely.
+
+### What "steer" means per harness
+
+Steer always POSTs immediately; how it lands depends on the harness:
+
+Steer always POSTs immediately (client-side, no runner change); how it lands
+depends on the harness. The steer button is shown for **all** native sessions —
+the runner delivers uniformly (POST → buffer → drain → hand to app, all natives'
+`run_turn` return right after delivery), and the app decides what to do with a
+message that arrives mid-response:
+
+| Harness | Steer delivery | Mid-turn? |
+|---------|----------------|-----------|
+| claude-sdk / codex-sdk / pi-sdk | runner **live injection** (`_live_response_id` gate) | ✅ deterministic |
+| cursor-sdk / copilot-sdk | buffer & drain | ❌ next turn |
+| **codex-native** | explicit **`turn/steer`** RPC when a turn is active | ✅ deterministic *(verified)* |
+| **claude-native** | `send-keys` into the **live pane**; the TUI folds the paste into the response | ✅ verified (best-effort timing) |
+| cursor-native / hermes-native | `send-keys` paste into the **live pane** (`supports_enqueue=True`) | ⚠️ app-defined — mechanism confirmed in code, **not yet verified live** |
+| pi-native | queued to the **resident extension** (`supports_enqueue=True`) | ⚠️ app-defined — mechanism confirmed in code, not yet verified live |
+| opencode-native | HTTP prompt (`supports_enqueue=True`); the native server has **no live-steer endpoint** → admitted as a new prompt, promoted by the server's own queue at turn end | ❌ next turn (code-confirmed) |
+| qwen / goose / kimi / kiro / antigravity -native | paste / file / RPC into the app (`supports_enqueue=True`) | ⚠️ app-defined — not yet verified live |
+
+> **TODO (live verification):** every native harness above reports
+> `supports_live_message_queue = True` and its delivery mechanism is confirmed
+> in code (see the enqueue path per harness), but whether the vendor app folds
+> the steered message in **mid-response** vs. at the **next turn** is confirmed
+> against a *live* runner only for claude-native + codex-native. Run a live
+> steer per harness to upgrade the ⚠️ rows. opencode-native is settled: its app
+> server exposes no live-steer endpoint, so the steered message is always
+> promoted at the next turn boundary.
+
+**No runner change is required for native steer** — every native `run_turn`
+returns right after delivering the input (decoupled from the response), so the
+drain fires the next message quickly and it reaches the app while the prior
+response is likely still running; the app does its own steering. Frame the UX
+honestly: *"send now; the agent folds it into current work if it can"* — which is
+exactly how native type-ahead already feels. Do **not** promise deterministic
+mid-turn for the unverified natives.
+
+**Steer is not interrupt.** In every case above, steer *does not cancel* the
+running turn — the message is folded in at the agent's next natural breakpoint
+(after the current tool/step completes), the same feel as steering native Claude
+by typing while it works. For SDK, `enqueue_session_message` adds the message to
+the running session's queue; the SDK surfaces it at its next turn-boundary — no
+teardown. This is distinct from the **Interrupt** button, which really does
+cancel the turn (`turn.cancel()`).
+
+### Edges to handle
+
+| Edge | Rule |
+|------|------|
+| POST fails after promote | revert the bubble to the queue (or error-badge it) |
+| Agent goes idle mid-edit | editing pins the message out of auto-flush until re-committed |
+| Native mirror-back | consume/mirror still needed as a **reconcile** signal (id-match the optimistic bubble to the real transcript item) so native round-trips don't double-render |

+    and conversation_id in _live_response_id  # a response is actually streaming
+)
+```
+
+### Native decoupling (why paste-steer works)
+
+Native `run_turn` returns as soon as `send-keys` finishes pasting (not when the
+agent finishes). `_active_turns` clears immediately, so the buffer drains the
+next message quickly and it pastes into the still-live pane — the native app then
+decides to steer it. `_native_pane_status` is the reliable liveness signal for a
+long autonomous native turn (since `_active_turns` clears early).

 ## Transport drivers: the real ceiling on "all dimensions"

-Behavioral probes run through a **transport driver** keyed by transport class
-(SDK in-proc HTTP, tmux TUI, app-server, HTTP/SSE). A harness that reuses an
-existing transport class is fully covered. A harness that invents a novel
-transport degrades its transport-dependent probes to `SKIPPED`/`UNKNOWN` until a
-driver for that class exists — but model-agnostic dimensions (streaming, MCP,
-policy, cost) stay covered regardless.
+Behavioral probes run through a **transport driver** resolved from the
+harness *family* plus flags: SDK harnesses default to `full-server` (`--fast`
+picks `sdk-inproc`), natives use `native-tui`, and `--transport NAME` overrides
+the family for any harness. A probe calls
+*semantic* methods on the driver (`run_basic_turn`, `run_streaming_turn`,
+`run_tool_turn(deny=...)`, `run_interrupt_turn`); the driver owns the
+*mechanism* and the probe owns the *interpretation*, so one probe runs across
+transports that reach the same capability by different means.

-This is why "run the bench, see all verdicts, zero code" is true *for any
-harness reusing a known transport class*, and honest about the one case where it
-is not.
+Three drivers exist today (see "Current state" above): `sdk-inproc`,
+`full-server`, `native-tui`. Two consequences fall out of this design:

-## Phasing
+- A dimension is only observable where a driver exercises it. Tool calling and
+  Policy DENY need `full-server`; on `sdk-inproc`/`native-tui` they report `·`.
+  A `·` therefore often means "this transport can't exercise it here," not "the
+  harness lacks it" (see "Which transport exercises which dimension").
+- A harness that invents a *novel* transport (neither wrap-subprocess, full
+  server, nor native tmux) would degrade its transport-dependent probes to
+  `SKIPPED`/`UNKNOWN` until a driver for that class exists.

- **MVP (P0).** Layer 0 profile/manifest + Layer 1 offline conformance + Layer 2
-  P0 probes (basic turn, streaming, MCP/tool-calling, interrupt, policy DENY,
-  model override) + the **SDK in-proc transport driver** + report with `DRIFT`
-  column. Wire the SDK harnesses already in `HARNESS_PROBES` (claude-sdk, codex,
-  pi, openai-agents).
- **P1.** Steering, live-queue, resume/fork, elicitation ASK, reasoning, images,
-  cost, compaction; the tmux / app-server / HTTP-SSE transport drivers; the
-  remaining SDK + all native harness profiles.
+So "run the bench, see all verdicts, zero code" is true *for any harness
+reusing a known transport class*, and honest about the cases where a dimension
+or a transport is not yet wired.
+
+## Current state (shipped)
+
+The MVP and most of phase-2 are landed. What exists on `main` today:
+
+- **Layer 0/1/2** — profile/manifest, offline conformance (runs in CI via the
+  `misc` pytest group), and the six P0 live probes (basic turn, streaming,
+  tool calling, policy DENY, model override, interrupt) with the `DRIFT`
+  column.
+- **Three transport drivers**, selected by harness *family* with flag overrides:
+  - `sdk-inproc` — drives a harness wrap subprocess directly (the four P0 SDK
+    harnesses: claude-sdk, codex, pi, openai-agents).
+  - `full-server` — a real server + runner; the only transport that exercises
+    **Tool calling** and **Policy DENY** as server-dispatched, policy-gated
+    calls (SDK harnesses only — it registers via an agent bundle).
+  - `native-tui` — a resident vendor CLI in a runner-owned tmux pane, driven
+    over the session HTTP surface via a host daemon.
+
+  SDK harnesses default to **`full-server`** — the fullest coverage, and a
+  strict superset of what `sdk-inproc` observes (everything sdk-inproc does,
+  *plus* Tool calling + Policy DENY). `--fast` opts the SDK family down to
+  `sdk-inproc` when you want to skip the server boot (those two dimensions then
+  report `·`). Native harnesses have a single transport `--fast` does not touch.
+  An explicit `--transport NAME` overrides the family default for any harness
+  and is mutually exclusive with `--fast`.
+- **Capability-derived matrix** — descriptive columns and declared verdicts
+  come from `harness_capabilities()` (the seam; see
+  `designs/harness-capabilities-bench-seam.md`), so a harness added to the
+  registry — in-repo *or* a community plugin — flows into the bench with no
+  bench edit.
+- **Native harnesses auto-derived** — every `NATIVE_TUI` harness is registered
+  and drivable by name; `native_vendor()` derives what the driver needs from
+  capabilities, with no per-vendor table.
+
+### Not yet wired
+
+- **Bench observation of Tool calling / Policy DENY on `native-tui`** — a
+  *driver gap, not a native-harness limitation*. Native harnesses do call tools
+  and enforce permissions; the bench cannot yet observe it on this transport.
+  A native tool call is the vendor's own tool (Bash/Read/...), not a
+  server-dispatched `function_call_output` the bench can force, and a native
+  deny is a vendor permission decision, not a server-side policy evaluation the
+  probe can assert against. So both cells show `·` (not measured), never `✗`.
+  Wiring the observation needs new driver work. (SDK harnesses get these via
+  `full-server`.)
+- **P1 dimensions** — steering, live-queue, resume/fork, elicitation ASK,
+  reasoning, images, cost, compaction. Probes not written yet (report
+  `UNKNOWN`).
+- **Server-side native-agent seeding is a hardcoded list** — see the
+  plugin-seamlessness note below; this is the main gap between "the bench is

+**You do not need to live-probe every harness on every host — and you cannot.**
+Each native harness needs its own vendor CLI logged in (a login the bench
+cannot provision), so no single host has them all. The two layers split the
+work:
+
+- **Offline conformance** already covers every harness in CI — registration,
+  the declared matrix, capability derivation. No host access needed.
+- **Live probes** only answer "does observed behavior match the declaration?"
+  You get value from live-probing a harness where the declaration is unverified
+  or might be wrong — not from chasing 100% coverage on one box.
+
+Run the full set on whatever host you have (`--profile oss`); harnesses whose
+vendor CLI is absent or logged out **skip cleanly** (they do not fail or abort
+the run). Read two signals only: any `!!` DRIFT, and any harness you *can* run
+that shows an unexpected `✗` / `·`. A single live run is a spot-check, not a
+gate — live probes are non-deterministic (model behavior, timing), so re-run
+before treating one `·`/timeout as a regression. Drift coverage is cumulative:
+each host that has harness X logged in contributes a live check for X.
+
+## Streaming is a binary declared capability
+
+A recurring subtlety worth stating: the `streaming` capability is **binary** —
+a harness either forwards token-level deltas (`SUPPORTED`) or it does not
+(`UNSUPPORTED`). `PARTIAL` is a *probe observation only*: the streaming probe
+returns it for the ambiguous coalesced-single-delta case against a `SUPPORTED`
+declaration. It is **never a declared value**. Declaring a non-streaming
+harness as `PARTIAL` drifts against reality, because the probe reports zero
+deltas as `UNSUPPORTED`, not `PARTIAL`.
+
+**Declare `streaming=False` only from a live observation of 0 deltas** — a
+static "the forwarder posts no delta" grep is *not* sufficient. That grep once
+flipped seven natives to `False` in one batch; a live run then showed
+pi-native streams (7 deltas) despite having no delta-posting forwarder, so the
+flip was reverted. Only three natives are declared non-streaming today, each
+live-verified at 0 deltas: **kiro-native, cursor-native, qwen-native**. The
+rest default to `streaming=True` (the honest default: if one turns out not to
+stream, the bench flags a real drift on the next run, rather than a false
+`False` that silently drifts the moment the harness *does* stream).
+
+## Which transport exercises which dimension
+
+Not every dimension is observable on every transport, so a `·` (SKIPPED) in a
+run always means "the bench did not measure this here," never "the harness
+lacks it." Two dimensions in particular only get a real verdict on the
+`full-server` transport:
+
+| Dimension | sdk-inproc (`--fast`) | full-server (default) | native-tui |
+|---|---|---|---|
+| Basic turn, Streaming, Model override, Interrupt | ✓ | ✓ | ✓ |
+| **Tool calling** | · (harness dispatches tools internally) | ✓ (server-dispatched builtin) | · (bench can't observe vendor tools yet) |
+| **Policy DENY** | · (wrap-direct: no tool-call policy hook) | ✓ (spec-baked deny, enforced) | · (bench can't observe vendor deny yet) |
+
+The `native-tui` `·` is a *bench observation gap, not a native-harness
+limitation*: native harnesses do call tools and enforce permissions, but a
+native tool call is the vendor's own (Bash/Read/...) and a native deny is a
+vendor permission decision, neither of which is the server-dispatched,
+policy-gated call the probe watches for. Giving those cells a real verdict
+needs new driver work, not a change to the harnesses.
+
+Because `full-server` sees everything `sdk-inproc` does *plus* these two, it is
+the **default** for SDK harnesses — a plain live run proves Tool calling and
+Policy DENY out of the box:
+
+```
+python -m tests.harness_bench --harness claude-sdk --profile oss
+```
+
+Live-verified: `claude-sdk` completes the full matrix on `full-server` —
+Tool calling `✓` and Policy DENY `✓` (the deny is delivered and the blocked
+call does not stall the turn). Add `--fast` to trade that coverage for a quicker
+run on `sdk-inproc`; those two columns then show `·`, since neither `sdk-inproc`
+nor `native-tui` (for natives) routes a tool call through a server policy
+evaluation.
+
+`full-server` covers **SDK harnesses only** — it registers the harness via an
+agent bundle, which is the SDK-wrap path; native harnesses need the host-daemon
+provisioning the `native-tui` driver owns. So Tool calling / Policy DENY on
+native harnesses are not observed by *any* transport yet — a bench follow-up,
+not a native-harness gap — distinct from the `--fast` (sdk-inproc) `·`, which
+is a transport limitation the default `full-server` run already answers for SDK
+harnesses.
+
+## Plugin seamlessness: where it is and isn't
+
+The original goal (option B) was that a *community* harness ships a
+`BenchProfile` and runs with `--harness <name>` and no bench edits. For the
+**bench itself, that holds**: profile resolution, capability derivation, and
+`native_vendor()` all read `harness_capabilities()`, which discovers community
+plugins via entry points. A plugged-in harness needs zero bench code to be
+recognized.
+
+The seam is **one level down, in the omnigent server**. A native harness is
+only drivable once the server has seeded a built-in `<harness>-native-ui`
+agent, and that seeding is a **hardcoded list** in
+`server/app.py:_ensure_default_agents` — one `_ensure_default_<harness>_agent()`
+call per harness. goose-native and hermes-native were in the capability
+registry but omitted from that list, so the bench (correctly) reported them
+`not auto-registered on the server` until the seeders were added.
+
+So: **the bench is plugin-seamless; the server's native-agent seeding is not,
+and the bench inherits that seam.** A community native plugin today resolves in
+the bench, then fails at registration because nothing seeds its UI agent. The
+clean fix is to make `_ensure_default_agents` iterate `native_agents()` from
+the registry (which already includes plugins) instead of a hardcoded call list
+— then native harnesses and plugins register automatically. This is the highest
+-leverage remaining item: it is the difference between "the bench is plugin-
+ready" and "a plugged-in native harness works end to end".
+
+## The self-enforcing table in practice (drift case studies)
+
+`reconcile()` turns a false capability declaration into a `DRIFT`. This is not
+theoretical — the bench caught several real declaration errors this way, each
+resolved by correcting the *source* (the capability model), not the bench:
+
+- **kiro-native / streaming.** Declared `SUPPORTED`, observed 0 deltas
+  (`!!✓>✗`). kiro mirrors each complete assistant message rather than streaming
+  tokens. Corrected to `streaming=False`.
+- **pi-native / streaming (a fixed over-correction).** A static grep had flipped

+`.vsix` and the release tag, so they can't diverge. The `.vsix` is built from a
+**frozen `release/vscode-v<version>` branch**, not `main`, so commits that land

-1. **Open the release PR.** Run the **VS Code Extension Release PR** workflow

-   `editors/vscode/package.json`, adds a `CHANGELOG.md` section, and opens a

+1. **Cut the release branch.** Run the **VS Code Extension Release PR** workflow

+   `Release (vscode): v0.2.0` PR. (A `dry_run: true` pass just shows the diff in
+   the run summary without pushing.) Review the PR — but **don't merge yet**.

-   builds the `.vsix`, attaches it and its `.sha256`, and creates a **draft**

+   tag namespace kept separate from the Python release tags `v[0-9]*`). A
+   `dry_run: true` pass builds and checksums without creating the release.
 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

+Revision ID: o1a2b3c4d5e6
+Revises: n1a2b3c4d5e6
+Create Date: 2026-07-07 00:00:00.000000
+
+Removes the back-pointer ``agents.session_id`` (FK to ``conversations.id``)
+in favour of an explicit ``agents.kind`` column (``'template'`` |
+``'session'``) that carries the same distinction without a circular
+reference.  The upgrade reads ``session_id`` before dropping it to back-fill
+``kind`` correctly.  The forward pointer ``conversations.agent_id`` remains
+the authoritative runtime link; ``kind`` is set at row-creation time and
+never changes.
+
+Also adds ``ix_conversations_agent_id`` to speed up "find the conversation
+that owns this agent" lookups (used in ``replace_agent`` and
+``fork_conversation``).
+
+SQLite note: ``conversations.agent_id`` is a FK to ``agents.id`` with
+``ON DELETE CASCADE``.  SQLite runs migrations with ``PRAGMA foreign_keys = ON``
+so any ``batch_alter_table`` that drops and recreates ``agents`` would
+cascade-delete bound conversations.  Both upgrade and downgrade issue
+``PRAGMA foreign_keys = OFF`` (SQLite-only, guarded by dialect) before the
+batch operations and ``PRAGMA foreign_keys = ON`` after.  ``recreate="always"``
+is also set on SQLite and ``"auto"`` on other dialects.

+"""Make conversations.title NOT NULL, back-filling NULLs with empty string.
+
+Revision ID: s1a2b3c4d5e6
+Revises: r1a2b3c4d5e6
+Create Date: 2026-07-07 00:00:00.000000
+
+The ``conversations.title`` column was nullable, using NULL to represent
+untitled conversations. This migration converts NULL to empty string so
+the column can be declared NOT NULL — keeping the DB constraint tight while
+the application layer continues to treat ``''`` and ``None`` as equivalent
+at the entity boundary (the store converts between the two).
+
+Upgrade path:
+1. Back-fill every NULL title to ``''`` with a plain UPDATE.
+2. Alter the column to NOT NULL (batch rebuild on SQLite since it cannot
+   alter column constraints in-place; native ALTER on other dialects).
+   No PRAGMA foreign_keys guard needed — all FK constraints were removed
+   in migration p1a2b3c4d5e6.
+
+Downgrade path:
+1. Rebuild the table restoring ``title`` to nullable.
+2. Convert every ``''`` title back to NULL so the data looks pre-migration.
+
+Uniqueness semantics across backends
+-------------------------------------
+``ix_conversations_parent_title_unique`` is ``UNIQUE(parent_conversation_id,
+title)`` scoped to rows where ``parent_conversation_id IS NOT NULL`` (partial
+index on SQLite/Postgres; full index on MySQL which lacks partial-index support).
+
+The empty-string sentinel (``''``) that now represents untitled conversations
+is safe on all backends:
+
+- **Top-level conversations** (``parent_conversation_id = NULL``): the partial
+  index excludes them on SQLite/Postgres, and MySQL allows multiple ``(NULL,
+  '')`` rows because NULL values are treated as distinct in unique indexes.
+- **Sub-agent conversations** always receive a non-empty derived title in
+  production (e.g. ``"agent_type:session_id"``), so ``title = ''`` never
+  occurs for children — no conflict on any backend.

+
+Host names come from ``~/.omnigent/config.yaml`` and are short identifiers
+like ``"corey-laptop"``. 256 characters is far more than needed; 64 matches
+every other short-identifier column in the schema and keeps the composite
+primary key (workspace_id, owner, name) compact.
+
+No FK constraints reference ``hosts.name`` (all FKs were removed in
+p1a2b3c4d5e6), so no PRAGMA guard is required and no dependent indexes need
+manual rebuilding — the batch rebuild recreates the table DDL from the current
+metadata (String(64)) and the only constraint on ``name`` is its role as a
+composite PK member.
+
+Upgrade path:
+  Batch-rebuild the ``hosts`` table, narrowing ``name`` from VARCHAR(256)
+  to VARCHAR(64). recreate="always" on SQLite (cannot ALTER column types
+  in-place); "auto" on other dialects.
+
+Downgrade path:

+"""Convert enum-like varchar columns to SMALLINT int codes.
+
+Revision ID: u1a2b3c4d5e6
+Revises: t1a2b3c4d5e6
+Create Date: 2026-07-07
+
+Several low-cardinality closed-set columns were stored as ``VARCHAR``
+guarded by string ``CHECK`` constraints. This migration converts them to
+compact ``SMALLINT`` integer codes (client-side name↔int conversion lives
+in ``omnigent.db.enum_codecs``), matching the existing int-coded
+``session_permissions.level``. The string names remain the contract above
+the store layer, so only the stored representation changes.
+
+Columns converted (name → code):
+
+- ``conversations.kind``          default=1, sub_agent=2
+- ``conversation_items.type``     message=1 … terminal_command=11
+- ``conversation_items.status``   completed=1 (in_progress=2, incomplete=3,
+                                   failed=4 reserved)
+- ``comments.status``             draft=1, addressed=2
+- ``account_tokens.kind``         invite=1, magic=2
+- ``policies.type``               python=1, url=2
+- ``hosts.status``                online=1, offline=2
+
+Each column is converted with the add-int-column → backfill-with-``CASE`` →
+drop-old-column → rename pattern (portable across SQLite and PostgreSQL),
+swapping the string ``CHECK`` for an integer one. ``render_as_batch`` (see
+migrations/env.py) rebuilds the SQLite table so the constraint swap lands.

+
+Previously the ``hosts`` PK was ``(workspace_id, owner, name)`` with
+``host_id`` carrying its own ``UNIQUE`` constraint (``uq_hosts_host_id``).
+This migration promotes ``host_id`` into the PK alongside ``workspace_id``,
+demotes ``owner`` and ``name`` to regular NOT NULL columns, drops the now-
+redundant ``uq_hosts_host_id`` constraint, and adds a new
+``uq_hosts_workspace_owner_name`` unique constraint so the upsert-on-connect
+rotation logic (which looks up by ``(workspace_id, owner, name)`` to detect a
+rotated ``host_id``) remains consistent.
+
+Dialect strategy
+----------------
+- **SQLite**: cannot ALTER a primary key in place; uses
+  ``batch_alter_table(recreate="always", copy_from=<spec>)`` to rebuild the
+  table from an explicit definition.  PRAGMA foreign_keys is toggled off/on
+  around the rebuild to prevent cascade issues.
+- **PostgreSQL / MySQL**: supports native ALTER TABLE DDL to drop and recreate
+  the primary key and swap the unique constraints without a table copy.
