The first interactive submit fired session.generateTitle() before
startPendingSubmission() painted the optimistic user row, and
tinyTitleClient.generate() spawned the local tiny-title subprocess
synchronously in #ensureWorker() before its first await. With a local
providers.tinyModel configured, subprocess-spawn latency therefore landed
ahead of the first frame, stalling the first prompt.
Paint the pending row before starting titling, and prewarm an idle,
unref'd worker at TUI startup via a no-op ping (no model load) so the
first submit reuses a live subprocess.
Fixes#6462
- Replaced tool-based `set_title` invocation with XML-style `<title>` marker tags for session title discovery.
- Implemented robust JSON-unwrapping logic to handle and sanitize title generation outputs.
- Updated model registry in catalog with new model support, provider prefixes, and metadata adjustments.
- Synchronized system prompt documentation and test suites to reflect the new marker-based generation flow.
When the user set `providers.tinyModel` to a local key, `generateSessionTitle`
still raced local against the online `smol` path with a 10 s timeout and
silently fired the online request whenever the local worker returned `null`
(unknown key, model not downloaded, transformers.js failure). The online path
resolves the `smol` role through `priority.json` (haiku → flash → mini → …);
with an `OPENROUTER_API_KEY` picked up from env, that silently billed
OpenRouter without consent.
Drop the race entirely for local choices: honor the user's setting, log a
warning on local failure, leave the session untitled. The `raceFirstNonNull`
helper and `TITLE_LOCAL_FALLBACK_DELAY_MS` had no other consumer and are
removed; the obsolete \"silently bills online when local fails\" tests are
flipped into regressions that lock the no-fallback contract, including the
unknown-key path (e.g. \"ollama:gpt-oss\") which previously also leaked
straight through to the online billing path.
Fixes#3187
- add discovery of `TITLE_SYSTEM.md` and pass it through interactive startup context
- route custom title prompts to online and local tiny title generators via protocol
- update session-title docs and changelog with override behavior
- add tests for prompt discovery, forwarding, and fallback to bundled title prompts
Move bundled models, model cache/manager, thinking metadata, effort helpers,
provider descriptors/discovery, wire constants, and model identity utilities
into the new @oh-my-pi/pi-catalog package.
Update pi-ai to keep provider runtime/auth concerns, move catalog provider
metadata into CATALOG_PROVIDERS, and migrate coding-agent, agent, stats, docs,
and tests to import catalog values from pi-catalog.
Split coding-agent model registry helpers into discovery, roles, and models
config modules while preserving registry orchestration.
BREAKING CHANGE: @oh-my-pi/pi-ai no longer exports catalog subpaths such as
/models, /model-cache, /model-manager, /model-thinking, /effort,
/provider-models*, discovery helpers, and provider wire constants; use the
matching @oh-my-pi/pi-catalog subpaths instead.
Stopped the tiny-title subprocess from inheriting stdout and stderr so native model runtime output cannot corrupt the interactive scrollback. Added a regression test for worker stdio configuration.\n\nFixes #2206
- Updated the initial render intent to carry a `clearScrollback` flag.
- Adjusted first-frame rendering logic to preserve existing scrollback by default and clear only when requested.
- Added `resolver` stubs to coding-agent and web-search test registries for interface compatibility.
- Added persistent settings in the Providers tab for ONNX execution provider and quantization/precision, replacing env-var-only configuration.
- PI_TINY_DEVICE and PI_TINY_DTYPE env vars still override the matching setting at spawn time.
- Added tinyWorkerEnvOverlay to map settings onto worker env without clobbering explicit env vars.
- Updated docs and tests to reflect the new setting-first resolution order.
- Updated hashline streaming preview tests to generate snapshot-tagged section headers and use an in-memory snapshot store.
- Replaced untagged file markers in multi-section preview inputs with `formatHashlineHeader` values derived from recorded file contents.
- Changed the bash command error test to expect a returned `isError` result with exit code 1 instead of a rejected promise.
- Added tiny-title protocol contracts, including progress-state unions, message payloads, and transport interfaces.
- Added title text utilities to truncate long inputs, wrap `<user-message>` blocks, and normalize generated titles.
- Added tiny-title model registry and helpers with type-safe keys and runtime optional loading via optionalDependencies.
- Added client-side worker orchestration with spawn fallback, request queueing, progress/error routing, and smoke-test APIs.
- Added worker runtime for model resolution, prompt-based inference, lock-based install retries, and close-time cache clear.
- Added `get(path)` support in test `createSettings` to return tiny model setting for `providers.tinyModel`.
- Updated `createSettings` in tests to accept optional `tinyModel` with default `"online"`.
- Added `flushMicrotasks()` and helper factories for test settings, registry stubs, and online model mocks.
- Added tests for `raceFirstNonNull`, `generateSessionTitle` routing, and providers tinyModel enum validation.
