F6: defer the JSON -> YAML migration out of ConfigFile's constructor and
add an async path so the boot sequence stops blocking the event loop on
sync I/O. New ConfigFile.tryLoadAsync/loadAsync/loadOrDefaultAsync/
getMtimeMsAsync and static ConfigFile.warmup. The migration is now
idempotent (per-process cache) so relocate() does not re-run it.
ModelRegistry.create(authStorage, modelsPath?) is a new async factory
that runs the warmup before the sync constructor's bundled-model load.
Production call sites (main.ts, sdk.ts, task/executor.ts, commit
pipelines, SDK example) all switched. Sync new ModelRegistry(...)
constructor is still supported for tests.
F2: rewrite MemorySessionStorage's mirror as { chunks: string[]; byteLen;
mtimeMs } so writeLineSync appends a single chunk in O(1) instead of
read-modify-writing the entire file (which was O(N) per append, O(N^2)
per session). statSync now reports true UTF-8 byte length instead of
character count. readTextPrefix walks chunks until the byte budget is
exhausted instead of materialising the full mirror.
Also rolls in per-package CHANGELOG entries for F1-F8.
F3 (agent): mutate state.messages and state.pendingToolCalls in place on
appendMessage/popMessage/clearMessages/reset/tool_execution_start/_end
instead of allocating a fresh array/Set on every transition. Subscribers
that capture state.messages by reference now observe updates directly.
Public type signature unchanged.
F5 (ai): add parseStreamingJsonThrottled to utils/json-parse — a per-delta
wrapper around parseStreamingJson that skips the re-parse until the
buffer has grown by minGrowthBytes (default 256). Wired into every
provider's tool-call argument accumulator (anthropic, amazon-bedrock,
openai-completions, openai-codex-responses, openai-responses-shared) so
per-delta cost becomes O(N) in total buffer length instead of O(N²).
Every provider's toolcall_end still runs a final unthrottled parse, so
the published block.arguments is unchanged.
F8 (coding-agent): drop the per-delta structuredClone of streaming tool
arguments in ToolExecutionComponent.updateArgs. event-controller.ts and
ui-helpers.ts already spread their input into a fresh object on each
delta, so cloning here was dead work on the rendering hot path. Added a
reference-equality short-circuit so repeat calls with the same args
object skip the preview-diff and display refresh.
F1 (coding-agent): close the withFileLock mkdir-vs-writeLockInfo race that
let a losing contender wipe the winner's freshly-created lock directory.
Every lock now carries a per-process UUID token; releaseLock verifies the
token before fs.rm, and isLockStale no longer treats an info-less but
fresh dir (or a dir that vanished mid-check) as stale.
F4 (coding-agent): sanitize tabs and truncate oversized error strings in
formatErrorMessage so error renderings that embed file content
(apply_patch, hashline, etc.) cannot break terminal alignment or
overflow the line width.
F7 (ai): support named-tool routing on Google providers. Widens
GoogleSharedStreamOptions.toolChoice and GoogleGeminiCliOptions.toolChoice
to accept { mode: 'ANY'; allowedFunctionNames }. mapGoogleToolChoice
now converts ToolChoice { type: 'tool'|'function', name } to the wire
shape (mirroring mapAnthropicToolChoice). buildGoogleGenerateContentParams
and the gemini-cli request serializer honor the allow-list.

- Expanded search scope handling for virtual multi-file targets and executed grep only when searchable paths existed.
- Merged `searchVirtualResources` results into main output and rendered internal URL matches as accent lines.

- Documented URL path/range behavior and added tests for doc routing, missing-content errors, and `omp://` expansion.
- Added virtual internal URL path resolution in `SearchTool` via `InternalUrlRouter` for in-memory search.
- Added `omp://` root expansion so `search` resolves and scans each completion target.

- Updated edit argument preparation, preview generation, and streaming fallback rendering to use that derived input.
- Added renderer tests verifying raw hashline and apply_patch partial streams render target paths and patch content.
- Added an amend option to the save selector that prompts for feedback and returns amend, rejected, or aborted outcomes.
- When the user chooses amend, the controller regenerated the candidate using prior rule content plus feedback before attempting to save.

- Updated streaming edit preview generation to set `skipHashValidation` while streaming is active.
- Added streaming preview tests asserting stale hash errors are suppressed during streaming and surfaced after completion.
- Changed tiny-device preference resolution to always default to CPU instead of platform-specific DirectML/CUDA heuristics.
- Updated settings schema, documentation, and changelog text to describe the CPU default while keeping accelerated providers behind explicit `providers.tinyModelDevice`/`PI_TINY_DEVICE` choices.
- Updated ACP thought-level resolution to use a helper that prefers session.configuredThinkingLevel and falls back to session.thinkingLevel when unavailable.
- Added a private AcpAgent method to safely compute configured thinking level without assuming a method exists on every session.
- Extended the ACP event-mapper replay test session with configuredThinkingLevel so it follows the new lookup path.
- Added AUTO_THINKING as a configured thinking level in settings, schema, SDK, and session plumbing.
- Implemented per-turn auto reasoning classification with online/local prompts, effort clamping, and skip guards.
- Updated model selectors, ACP options, footer/status UI, and events to render auto and auto->resolved states.
- Added AUTO_THINKING parse/clamp tests and fixed local-module cycle and hashline preview regressions.
- Removed `trimTrailingPartialLine` from hashline preview path, as the streaming-tolerant parser already handles partial ops correctly; trimming stripped the sole payload of single-op patches, collapsing the preview to "No changes."
- Broadened trailing-section error suppression to apply during streaming regardless of section count, preventing transient mid-typed ops from wiping stable prior frames.
- Replaced fixed calendar timestamps with `minutesAgo()` so beam-store items stay within the 24h working-memory TTL.
- Broadened background-color assertion to match both truecolor (`48;2;`) and 256-palette (`48;5;`) terminals.

- Kernel spawn reuses the probed runtime from the availability result instead of re-resolving independently.
- Expanded test coverage for enumeration, fallback, and env isolation between candidates.
- Added `PI_TINY_DEVICE` env var to control ONNX execution provider (`gpu` default, `cpu`, `metal`, `cuda`, `dml`, `coreml`).

- Updated docs and model descriptions to drop CPU-specific language.
- Added clockwise sweeping dark segment animation to output block borders while bash/eval tool calls are pending/running.

- Changed sign-in flow handling to keep the scene active across providers and support cancellation during authentication.
- Changed glyph-mode picker initialization and rendering to preselect current preset and show live symbol previews.
- Updated setup wizard tests to use the `providers` scene id and cover the new web search tab path.
- Added setup wizard with provider login, glyph mode, and theme scenes shown once per setup version.
- Wired `omp setup` (no args) to trigger the wizard in a TTY; `--check`/`--json` still show help.

- Passed INSPECT_IMAGE_ENABLED flag into prompt rendering context.
- Added test verifying description omits inspect_image references when disabled.

- Added a new `providers.memoryModel` setting with tiny memory model options and `ONLINE_MEMORY_MODEL_KEY` default in settings.
- Updated Mnemosyne provider resolution so a configured local tiny model overrode remote completion and used new memory extraction and consolidation prompts.
- Expanded the tiny-model CLI registry to download and report all local tiny models (title plus memory) through a unified list.
- Updated local module loading to force TS syntax stripping for .ts/.tsx/.mts modules and use the matching Bun transpiler loader.

- Added tests verifying type-only imports are handled correctly in evaluator modules and rewritten code no longer contains type-only import declarations.
- Captured the operator's selected execution tier and passed it through plan approval options.
- Applied the stored model after exiting plan mode so #exitPlanMode's restore no longer reverts it before execution begins.
- Added a regression test that selects a different slider tier and verifies execution runs on the chosen model.
