Subject: [PATCH 1/7] freeze model + provider per run at creation time
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The model dropdown was broken in two ways: it wrote to ~/.rowboat/config/models.json
(the BYOK creds file, stamped with a fake `flavor: 'openrouter'` to satisfy zod
when signed in), and the runtime ignored that write entirely for signed-in users
because `streamAgent` hard-coded `gpt-5.4`. Model selection was also globally
scoped, so every chat shared one brain.

This change moves model + provider out of the global config and onto the run
itself, resolved once at runs:create and frozen for the run's lifetime.

## Resolution

`runsCore.createRun` resolves per-field, falling through:

  run.model    = opts.model    ?? agent.model    ?? defaults.model
  run.provider = opts.provider ?? agent.provider ?? defaults.provider

A new `core/models/defaults.ts` is the only place in the codebase that branches
on signed-in state. `getDefaultModelAndProvider()` returns name strings;
`resolveProviderConfig(name)` does the name → full LlmProvider lookup at
runtime. `createProvider` learns about `flavor: 'rowboat'` so the gateway is
just another flavor.

`provider` is stored as a name (e.g. `"rowboat"`, `"openai"`), not a full
LlmProvider object. API keys never get written into the JSONL log; rotating a
key in models.json applies to existing runs without re-creation. Cost: deleting
a provider from settings breaks runs that referenced it (clear error surfaced
via `resolveProviderConfig`).

## Runtime

`streamAgent` no longer resolves anything — it reads `state.runModel` /
`state.runProvider`, looks up the provider config, instantiates. Subflows
inherit the parent run's pair, so KG / inline-task subagents run on whatever
the main run resolved to at creation. The `knowledgeGraphAgents` array,
`isKgAgent`, and the per-agent default constants are gone.

KG / inline-task / pre-built agents declare their preferred model in YAML
frontmatter (claude-haiku-4.5 / claude-sonnet-4.6) — used at resolution time
when those agents are themselves the top-level agent of a run (background
triggers, scheduled tasks, etc.).

## Standalone callers

Non-run LLM call sites (summarize_meeting, track/routing, builtin-tools
parseFile) and `agent-schedule/runner` were branching on signed-in
independently. They all route through `getDefaultModelAndProvider` +
`resolveProviderConfig` + `createProvider` now; `agent-schedule/runner`
switched from raw `runsRepo.create` to `runsCore.createRun` so resolution
applies to scheduled-agent runs too.

## UI

`chat-input-with-mentions` stops calling `models:saveConfig`. The dropdown
notifies the parent via `onSelectedModelChange` ({provider, model} as names);
App.tsx stashes selection per-tab and passes it to the next `runs:create`.
When a run already exists, the input fetches it and renders a static label —
model can't change mid-run.

## Legacy runs

A lenient zod schema in `repo.ts` (`StartEvent.extend(...optional)` plus
`RunEvent.or(LegacyStartEvent)`) parses pre-existing runs. `repo.fetch` fills
missing model/provider from current defaults and returns the strict canonical
`Run` type. No file-rewriting migration; no impact on the canonical schema in
`@x/shared`.

Subject: [PATCH 5/7] convert Today.md track blocks to event-driven and batch
 Gmail sync events

Removes polling schedules from the up-next and calendar track blocks on
Today.md so they refresh only on calendar.synced events, and rewrites
the emails track instruction to consume a multi-thread digest payload.
Batches Gmail sync so one email.synced event covers a whole sync run
(capped at 10 threads per digest) instead of one event per thread,
which collapses Pass 1 routing calls for multi-thread syncs.

+- Start time is later this morning or this afternoon → upcoming: name the meeting and roughly when (e.g. "Design review later this morning." / "1:1 with Sam this afternoon.").
+- Start time is several hours out or nothing before then → focus block: frame the gap (e.g. "Next up is the all-hands at 3pm — good long focus block until then.").
 
-Lead based on how soon the next event is:
-- Under 15 minutes → urgent ("Standup starts in 10 minutes — join link in the Calendar section below.")
-- Under 2 hours → lead with the event ("Design review in 40 minutes.")
-- 2+ hours → frame the gap as focus time ("Next up is standup at noon — you've got a solid 3-hour focus block.")
+Use the event's start time of day ("at 3pm", "this afternoon") rather than a countdown ("in 40 minutes"). Countdowns go stale between syncs.

 If you find quick context in knowledge/ that's genuinely useful, add one short clause ("Ramnique pushed the OAuth PR yesterday — might come up"). Use workspace-grep / workspace-readFile conservatively; don't stall on deep research.

+Event-driven path (primary): the agent message will include a "Gmail sync update" digest payload describing one or more freshly-synced threads from a single sync run. The digest lists each thread with its subject, sender, date, threadId, and body. Iterate over every thread in the payload and decide per thread whether it warrants surfacing. Skip marketing, auto-notifications, closed-out threads, and other low-signal mail. For threads that are attention-worthy, integrate them into the existing digest: add a new email block for a new threadId, or update the existing block if the threadId is already shown. If NONE of the threads in the payload are attention-worthy, skip the update — do NOT call update-track-content. Emit at most one update-track-content call that covers the full set of changes from this event.
 
 Manual path (fallback): with no event payload, scan gmail_sync/ via workspace-readdir (skip sync_state.json and attachments/). Read threads with workspace-readFile. Prioritize threads whose frontmatter action field is "reply" or "respond", plus other high-signal recent threads.

Subject: [PATCH 6/7] configurable kg / meeting / track-block model overrides
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Bring back per-category model selection that 5c4aa772 dropped, plus add a
new track-block category. Each is a BYOK-only override on `LlmModelConfig`
(`knowledgeGraphModel`, `meetingNotesModel`, `trackBlockModel`); signed-in
users always get the curated gateway default and never hit the on-disk
config.

Three helpers in core/models/defaults.ts — `getKgModel`,
`getTrackBlockModel`, `getMeetingNotesModel` — each check `isSignedIn`
first (fast path) and fall through to `cfg.<field> ?? cfg.model` for BYOK.

The model is now picked at the invocation site rather than via runtime
agent-name branching: each top-level `createRun` for a polling KG agent
or a track-block update passes `model: await getXxxModel()`. The `model:`
declarations on the affected agent YAMLs are dropped — they were dead
code under the per-call override. Standalone (non-run) callers
`track/routing` and `summarize_meeting` use the helpers inline.

Settings dialog and the two onboarding flows surface the two new fields
("Meeting Notes Model", "Track Block Model") next to the existing
"Knowledge Graph Model"; `repo.setConfig` persists all three per-provider.

Note: the signed-in `RowboatModelSettings` panel still has its
now-defunct kg selector; that's a UI cleanup for a later pass.

Subject: [PATCH 7/7] allow per-track model + provider overrides

Track block YAML gains optional `model` and `provider` fields. When set,
the track runner passes them through to `createRun` so this specific
track runs on the chosen model/provider; when unset the global default
flows through (`getTrackBlockModel()` + the resolved provider).

The track skill picks up the new fields automatically via the embedded
`z.toJSONSchema(TrackBlockSchema)` and adds an explicit "Do Not Set"
section: copilot leaves them omitted unless the user named a specific
model or provider for the track. Common bad reasons ("might be faster",
"in case it matters", complex instruction) are called out so the
defaults stay the path of least resistance.

Track modal Details tab shows the values when set, in the same
conditional `<dt>/<dd>` style as the lastRun fields.

+## Do Not Set ` + "`" + `model` + "`" + ` or ` + "`" + `provider` + "`" + ` (almost always)
+
+The schema includes optional ` + "`" + `model` + "`" + ` and ` + "`" + `provider` + "`" + ` fields. **Omit them.** A user-configurable global default already picks the right model and provider for tracks; setting per-track values bypasses that and is almost always wrong.
+
+The only time these belong on a track:
+
+- The user **explicitly** named a model or provider for *this specific track* in their request ("use Claude Opus for this one", "force this track onto OpenAI"). Quote the user's wording back when confirming.
+
+Things that are **not** reasons to set these:
+
+- "Tracks should be fast" / "I want a small model" — that's a global preference, not a per-track one. Leave it; the global default exists.
+- "This track is complex" — write a clearer instruction; don't reach for a different model.
+- "Just to be safe" / "in case it matters" — this is the antipattern. Leave them out.
+- The user changed their main chat model — that has nothing to do with tracks. Leave them out.
+
+When in doubt: omit both fields. Never volunteer them. Never include them in a starter template you suggest. If you find yourself adding them as a sensible default, stop — you're wrong.
