- Derived device_id from both install id and account UUID via v2 hash domain.
- Fell back to v1 install-only hash when no account UUID is present.
- Threaded account UUID through Anthropic metadata user_id resolution.
- Substituted injected on-disk roots for `local://` in read/write/append (Python and JS).
- Pinned `local://` to the session's own root so eval writes land where reads resolve.
- Rejected path traversal and unknown `scheme://` paths instead of creating junk `local:` dirs.
- Added unit and integration tests covering resolution, guards, and plain-path passthrough.
- Added `getRules()` to `TtsrManager` to expose registered TTSR rules in registration order.
- Updated `createAgentSession` to append `ttsrManager.getRules()` to active rules so TTSR rules can be resolved through `rule://`.
- Rewrote the rulebook matching docs to reflect that `rule://` now includes registered TTSR rules and why.
- Rendered added/current lines without `+`/space prefix padding.
- Collapsed long added runs with a bare `…` marker instead of `+…`.
- Normalized adjacent ASCII/Unicode elision markers to one `…`.
- Updated live transcript state derivation to treat a trailing-line extension with unchanged rows as append-only.
- Replaced the prior append-grew heuristic with preserved-row checks so non-rewritten history is not marked volatile.
- Added a regression test covering in-place streaming line growth and scrollback commit safety in transcript containers.
- Added Homebrew and mise install-source detection in `resolveUpdateMethod` using prefix, bin-dir, and shim checks.
- Added `runUpdateCommand` delegation to `updateViaHomebrew` and `updateViaMise` for manager installs.
- Changed `--force` behavior for package managers to run `brew reinstall` and `mise install --force`.
- Stopped aborted runs from waiting on provider iterator cleanup.
- Ran afterToolCall for completed executions after a run aborts.
- Ignored unknown Anthropic content blocks while preserving known ones.
- Kept sampling params and tool-result caching for disabled thinking.
- Added a new built-in TTSR rule `ts-no-test-timers.md` that flags `Bun.sleep`, `setTimeout`, and `setInterval` usage in `*.test.ts` files.
- Registered `ts-no-test-timers` in the built-in rules index so it ships with default discovery providers.
- Updated builtin-defaults tests to enforce rule-name uniqueness and verify the new rule only matches in `*.test.ts` scopes.
- Normalized image-content preprocessing in agent sessions now returns early when `content` is missing or not a string/array, avoiding invalid normalization paths.
- Updated agent-loop tests to verify partial tool calls are dropped when an assistant aborts before `toolcall_end`, with run completion reported via an assistant `stopReason` of `aborted`.
- Adjusted Anthropic alignment expectations to reflect a single trailing cache-control breakpoint on the final system block.
- Reworked classic and KITT shimmer intensity math to drive the scan head by a constant 30 cells/second.
- Introduced length-aware travel periods for classic padding and KITT ping-pong motion while removing the prior fixed-duration phase helpers.
- Updated shimmer tests to validate crest movement stays within one cell per 30fps frame and is consistent across text lengths.
- Updated `docs/ttsr-injection-lifecycle.md` to document `astCondition` behavior, including registration rules and tool-stream matching.
- Extended `packages/natives/test/native.test.ts` with new `astMatch` coverage for Smart matching, metavariable consistency, parse errors, and empty-language rejection.
- Serialized hook selector, input, and editor dialogs to prevent overlapping surfaces.
- Queued dialog requests FIFO and skipped requests aborted before they could be shown.
- Added a shared #presentDialog path for modal focus and hide lifecycle.
- Added astCondition to rule frontmatter parsing and rule metadata, with AST-grep normalization.
- Updated TTSR bucketing so astCondition-only rules are treated as interruptible matches.
- Added ts-redundant-clear-guard as a built-in JS/TS tool rule for guarded clear* calls.
- Added AST snapshot matching in agent sessions with per-stream cache throttling and cleanup.
- Set AskTool concurrency to exclusive so the tool runner executes ask calls serially.
- Updated the changelog to document the hanging ask failure when multiple asks were triggered concurrently in one batch.
- Added tree-sitter `enclosing_block_boundaries` API with line range models.
- Added N-API `enclosingBlockBoundaries` bridge and exported JS declarations.
- Replaced matching-bracket context resolution with source-aware block context in read and diff flows.
- Passed source path through diff/read generators to surface native block boundary previews.
- Synchronized shimmer progression by switching `shimmer.ts` to a shared 2-second phase sweep, with crest/head position interpolated across the full visible span.
- Updated classic and KITT intensity calculations so shimmer starts at index 0 and reaches index length-1 together for any task row length.
- Adjusted shimmer tests to assert crest boundary and phase alignment behavior across short and long strings.
- Removed `maxToolCallsPerTurn` from `AgentOptions`, `AgentLoopConfig`, and config serialization.
- Removed stream-loop cap enforcement, including the `toolcall_end` abort path and capped assistant messages.
- Removed Anthropic Opus 4.8 batch-cap resolver and agent-session sync logic from coding-agent.
- Updated tests and changelogs to align with uncapped tool-call behavior and dropped cap-specific cases.
- Added matching-bracket utilities to locate partner lines for visible spans.
- Added read tool output to use displayContent text and startLine for bracket-aware previews.
- Added matching-bracket context rows to generateDiffString and generateUnifiedDiffString.
- Adjusted diff row insertion to deduplicate and keep contiguous changed groups together.
- Replaced the moved-session stderr write with a structured logger.info call.
- Logged relocation metadata as `{ from, to }` fields for the re-rooting path.
- Tracked in-flight browser helpers with names and durations for timeout reporting.
- Wrapped observe, screenshot, and extract in per-op deadlines capped at 20_000ms.
- Updated timeout cancellation errors to list stalled helper names and elapsed time.
- Removed the mid-skip placeholder line that was output when skipping lines in the middle of a diff, relying instead on the line number jump to convey the gap. Removed the corresponding placeholder-filtering logic from the hashline diff preview that was handling these placeholders.
- Added atomicTokenPattern support to treat image and paste markers as indivisible tokens, enabling atomic deletion on backspace and forward-delete instead of character-by-character removal.
- Extended image marker format to include pixel dimensions [Image #N, WxH] and updated paste marker format to [Paste #N, +X lines] or [Paste #N, Y chars] with consistent comma-separated metadata.
- Implemented accent styling for paste markers in editor rendering while preserving hyperlinks for image markers, improving visual distinction between marker types.
- Refactored image reference handling to unified placeholder system supporting both image and paste markers with kind-aware rendering callbacks and regex patterns.
- Modified buildCompactDiffPreview to omit removed lines from output while preserving removal counts for offset tracking.
- Added logic to collapse long contiguous added runs with +<lineNum>... elision marker, keeping configurable edge lines on each side via new maxAddedRunContext option.
- Removed context-gap placeholder rows (... or ...) from model-facing preview, relying on line-number jumps to convey elision.
- Reorganized test suite by moving core contract tests to dedicated core-contracts.test.ts file and diff-preview tests to diff-preview.test.ts for better separation of concerns.
- Passed pending and input images into compaction queueing for steering and follow-up flows.
- Delivered queued follow-up/steer prompts with stored images via session.prompt and followUp.
- Normalized empty image arrays to undefined and cleared stale pending image state.
- Added regression tests for image-backed compaction queueing and follow-up forwarding.
- Changed runEvalAgent to always pass enableLsp: false when launching bridge subagents.
- Added a regression test asserting runSubprocess received enableLsp as false even when LSP is enabled by default.
- Renamed eval oneshot helper from llm() to completion() across JS/Python APIs.
- Remapped eval bridge internals to completion semantics (__completion__, runEvalCompletion, completion status op).
- Updated docs, prompts, and timeout guidance to describe completion() usage and behavior.
- Adjusted completion defaults for active-session model preference, fallback parsing, and slow-tier effort handling.
- Updated the title-system prompts to enforce 3-7 word, sentence-case session titles.
- Expanded handling guidance so non-task inputs can map to "none" and link/reference-only messages are summarized by intent.
- Updated the title tool description and generator comments to match the new sentence-case, 3-7 word title contract.
- Added macOS CI signing and notarization steps when APPLE_* secrets are configured.
- Added strict darwin verification checks to reject ad-hoc signatures and run smoke tests.
- Added Homebrew formula publishing from release assets with SHA-256 checksums.
- Added helper scripts for signing secret upload, entitlements, and release workflows.
The release_binary smoke probe spawns the tiny-title worker as a cold subprocess
of the compiled binary and pings it. On the contended macos-15-intel runner the
cold start (decompress + module-graph load, with a cold bun cache) blew past the
5s bound and failed the 15.10.3 release, while arm64/linux/win passed. The probe
only needs to prove the worker spawns and ponges at all, so the timeout is raised
to 30s — a dead worker still never ponges, so the check is unchanged in substance.
These three suites encoded pre-refactor behavior and broke the 15.10.3 release CI.
- event-controller read grouping: the group header count now reflects aggregated
display rows (distinct files), and a mid-turn visible-reasoning break finalizes
the prior group but keeps it live until pending reads settle (97ae0fd3, b5eff5b3).
- gallery harness: lsp no longer attaches an instance renderer (custom rendering
removed in d9d06134), so the custom-branch regression guard is retargeted to
task, which still attaches its renderer and merges call+result.
- eager-todo enforcement: the prelude reminder converts to a developer-role
message now that auxiliary messages map to developer for compaction (e13f2de5).
- Added an `insertCursorLine` helper to translate streaming insert cursors into preview line numbers.
- Implemented `buildStreamingSectionDiff` to group resolved edits by operation and emit deletions before insertions, stabilizing streamed cursor progression.
- Updated `computeHashlineSectionDiff` to use the streaming builder when `options.streaming` is enabled, while preserving existing Myers diff behavior for non-streaming paths.
- Introduced `AsideMessage` as a message-or-thunk union so aside providers can defer injection decisions.
- Updated agent loop handling to resolve aside thunks at injection time and skip entries that returned `null`, then switched the session yield queue to `drainLazy` for deferred message building.
- Added tests validating lazy aside evaluation and staleness-aware dropping when everything becomes stale after dequeueing.
- Replaced `readGroup.finalize()` with `readGroup.seal()` when ending assistant content, after tool runs, and at trailing read-group flushes to keep grouped reads in the live region until late results settle.
- Documented the fix in `packages/coding-agent/CHANGELOG.md` for grouped read rows that could freeze on terminals when results arrived after a sibling tool closed the run.
- Added a session-global file mutation counter and accessor methods to tool sessions.
- Updated the write tool to bump a file's mutation version after each write.
- Updated the edit tool to use session-wide mutation versions when checking stale deferred diagnostics.
- Added a sealed state to `ReadToolGroupComponent` to force-close a read group when a turn ends without a read result.
- Updated transcript finalization to treat pending read entries as active unless the group is sealed, preventing premature finalization when outputs are still in flight.
- Expanded turn-end pending-tool cleanup to seal `ReadToolGroupComponent` instances in addition to `ToolExecutionComponent`.
- Added a BlockResolution type and `onResolved` callback so `resolveBlockEdits` reports each anchor's resolved span for `replace block`/`delete block` edits.
- Updated patch application to return those spans on hash-match applies and omit them during drift-recovery paths where line numbers no longer align.
- Propagated the surfaced spans through the edit tool output and added/updated tests covering replace/delete block echo and drift behavior.
- Processed explicit multi-path `find` targets independently and merged scoped results.
- Ignored missing or invalid extra targets in multi-path `find` queries instead of failing the whole run.
- Deduplicated overlapping matches when combining per-target `find` results.
- Tracked streamed match paths to prevent repeated update rows during long-running scans.
- Routed background-job completions and late LSP diagnostics through the new non-interrupting aside channel so the model sees them mid-run between requests.
- Removed inline custom rendering from the LSP tool now that diagnostics surface through the shared transcript renderer.
- Added an agent loop test proving aside messages are delivered after tool results, before the next model request, without interrupting tool execution.
- Added a yield-queue test confirming stale entries are excluded, the queue is cleared, and re-draining yields no messages.
