- Added `IndexedSessionStorage` with `SessionStorageBackend` for index-based storage reads.
- Removed `readTextSync` from the public `SessionStorage` API and sync backends.
- Changed Redis and SQL backends to warm `{size, mtimeMs}` metadata and read via `readTextSlices`.
- Added per-path write queues and `drain()` to serialize operations and surface first failures.
- Previously only stripped dangling tool_use blocks from the trailing assistant turn; now scans all assistant turns on the resolved path.
- Builds a set of paired tool result IDs upfront to identify dangling calls anywhere in the message list.
- Adds a test covering a mid-path dangling turn alongside a correctly paired turn that must be preserved.
- Stripped `redactedThinking` blocks (encrypted, no downgradeable plaintext) from trailing assistant turns during context rebuild.
- Cleared `thinkingSignature` on `thinking` blocks so the encoder downgrades them to plain text, avoiding Anthropic's "modified latest assistant message" rejection.
- Extended existing test to cover signed/redacted thinking alongside dangling tool calls.
- Removed todo spinner interval state and rendering hooks from InteractiveMode, and in-progress or active-matched todos now use the static running glyph.
- Removed spinner-driven matcher caching and render updates from todo list generation so running state is based on direct content matching.
- Added build-session context tests that remove dangling assistant `toolCall` entries and drop trailing assistant turns that contain only tool calls.
- Added `recoverOrphanedBackups` to promote `.jsonl..bak` files back to their primary path when the primary is missing, preventing data loss after a mid-rename crash.
- Changed backup filename from dot-prefixed to plain `..bak` so the shared `*.bak` glob can find it on both real and in-memory storage backends.
- Surfaced the original EPERM as the error `cause` and included both original and retry messages when rollback also fails.
Replaced overwrite-style session rewrites with an EPERM fallback that moves the old session file aside before retrying and restores it if the retry fails.
Added regression coverage for active-session rewrite recovery so the session remains writable after the fallback.
Fixes#1337
- Added sync truncation helpers to recursively prepare session entries and externalize image data.
- Reworked session persistence to use synchronous preparation plus `writeSync` with close-state checks.
- Added synchronous session-storage APIs and rerouted write paths to `writeLineSync`/`readTextSync`.
- Added `BlobStore.putSync`, migrated hashing to `Bun.SHA256`, and updated hash tests accordingly.
- Removed export leakage by demoting many helper and const symbols to module-local scope.
- Renamed underscore-prefixed internals and cache fields, then updated related references and `satisfies never` checks.
- Deleted obsolete logic branches and helpers, including harmony-stream interruption flow and unused benchmark runtime helpers.
- Updated Biome config and manifests by broadening lint coverage and removing an unused `@napi-rs/cli` dev dependency.
- Adjusted tests and utilities to use renamed test helpers and remove redundant private test-only helpers/locals.
- Added session-draft persistence methods in SessionManager to write unsent editor text to an artifacts-sidecar draft file and delete it after single-shot consumption.
- Persisted editor text during interactive shutdown and restored that draft on resume when the editor was empty, enabling Ctrl+D draft recovery.
- Updated Ctrl+D handling in the editor/controller path and added tests covering draft round-trip, artifact cleanup, stale-draft eviction, and in-memory no-op behavior.
buildSessionContext walked the entry path and unconditionally overwrote
models.default from every assistant message's reported model. Temporary
fallbacks (retry fallback, context promotion) and codex-side model
downgrades both produce assistant messages tagged with a different model
id, which clobbered the user's explicit /model pick on resume and made
the session silently revert to the older model.
Treat assistant-message inference as a legacy fallback that only fills
in models.default when no explicit `model_change` with role="default"
has been seen on the path.
Fixes#849
- Standardized missing-file read errors and now return `File not found: <path>` for absent edit targets.
- Centralized AI provider, usage, and OAuth helpers into shared modules to remove duplicated logic.
- Migrated OAuth/API-key login flows to shared factory helpers and removed inline prompt/token-exchange code.
- Reused shared tools and formatter utilities for discovery, stream tails, LSP batching, and source formatting.
- Consolidated repeated test helpers and fixtures into shared modules, replacing inline helper duplicates.
- Replaced Snowflake session IDs with UUIDv7 for created, forked, branched, and resumed sessions.
- Derived cache session IDs from OpenAI request options and passed them into Responses client creation.
- Used derived session IDs for OpenAI `session_id`/`x-client-request-id` headers and `prompt_cache_key`; omitted headers when retention was none.
- Added tests for UUIDv7 session creation/branching and OpenAI cache-affinity default, override, and disabled-header modes.
- Documented UUIDv7 session handling and OpenAI cache-routing fixes in package Unreleased changelogs.
- Fixed memory leak by cancelling idle compaction timer on event controller disposal.
- Fixed session resumption to preserve last non-empty session when starting fresh.
- Fixed stash detection to use git ref resolution instead of output parsing for reliability.
- Fixed secret obfuscation to deobfuscate restored session messages locally while keeping LLM messages obfuscated.
- Fixed stash pop operation to preserve staged changes with --index flag after task branch merges.
- Changed idle compaction settings from enum to numeric type for flexible configuration.
sanitizeRehydratedOpenAIResponsesAssistantMessage now removes the
assistant providerPayload for Responses-family messages, not just the
stale thinkingSignature. After rehydration the native replay snapshot
belongs to a previous live provider connection and replaying it on a
warmed session causes 401 rejections from GitHub Copilot.
User/developer providerPayload is preserved by the caller since it
carries durable compaction and preserved history needed for valid cold
request reconstruction.
Fixes#592
- Made sessionDir parameter optional in SessionManager.create(), forkFrom(), continueRecent(), and list() methods with automatic default computation.
- Updated SessionManager.getDefaultSessionDir() to accept optional agentDir parameter for custom sessions root configuration.

- Added support for quoted paths in grep, ast_grep, and find tools to properly handle directory names with spaces.
- Improved ast_grep error messaging when no matches found with parse errors to suggest narrowing path/glob or setting language.
- Extracted path utility functions (resolveEquivalentPath, normalizePathForComparison, pathIsWithin, relativePathWithinRoot) to shared utils package.
- Added comprehensive test coverage for symlink alias resolution in status line path rendering and session directory handling.
- Added `attribution` option to `PromptOptions` for controlling billing and initiator attribution.
- Updated subagent prompts to explicitly set `attribution: "agent"` for accurate billing attribution.
- Refactored message attribution logic to use configurable `promptAttribution` with fallback defaults.
- Added test coverage for `attribution` option in subagent reminder prompts.
Fixes#439.
feat(coding-agent): added attribution option and explicit session directory control
- Added `attribution` option to `PromptOptions` for explicit billing and initiator attribution control.
- Updated `SessionManager.create()` to require both `cwd` and `sessionDir` parameters for explicit session directory control.
- Changed session directory naming for temporary working directories from `--` format to `-tmp-` prefix.
- Made `cwd` and `sessionDir` fields mutable in SessionManager to support session relocation.
- Fixed automatic migration of legacy session directories to new `-tmp-` prefixed naming scheme.
- Updated all test fixtures to pass both `cwd` and `sessionDir` parameters to `SessionManager.create()`.
Two /move bugs on Windows:
1. Quoted absolute paths (e.g. /move "C:\...") were treated as relative
because surrounding quotes weren't stripped before path.isAbsolute().
2. /move before any model response threw ENOENT because the session
.jsonl file hadn't been created on disk yet (lazy-persist).
Changes:
- Extract stripOuterDoubleQuotes() helper in path-utils.ts, use in
handleMoveCommand() with empty-after-strip guard
- Guard session file rename with existsSync in moveTo(), leaving
artifact dir rename independently guarded
- Guard #rewriteFile() with hadSessionFile || hasAssistant to preserve
lazy-persist while still updating header cwd for existing files
- Add comprehensive test suite (13 tests) covering all moveTo() edge
cases including header-only sessions, deferred persistence, and
artifact migration
- Resolved symlinked paths before passing to brush shell to keep `pwd` output aligned with canonical Git worktree paths.
- Added `resolveShellCwd` helper that safely resolves symlinks and falls back to original path on error.
- Added test case verifying symlinked directories are canonicalized before execution.
- Added serviceTier option to OpenAI providers for controlling processing priority and cost across agent, completions, responses, and codex APIs.

- Pinned @biomejs/biome dependency to exact version 2.3.12 in package.json and bun.lock.
- Applied consistent arrow function formatting across 489 files by removing unnecessary parentheses around single parameters.
- Removed blank lines after comment blocks and reorganized imports for consistency across the codebase.

- Added configurable bash interceptor rules with pattern-based command interception settings.
- Added AbortSignal support to 80+ web scrapers for request cancellation.
- Changed task tool to require explicit task `id` field and single `agent` parameter at top level.
- Removed `submit_review` tool - reviewers now use `complete` tool with structured output.
- Replaced Date.now() and crypto.randomUUID() with nanoid() for unique ID generation throughout codebase.
- Settings now use modelRoles map (e.g., { default: 'anthropic/claude-sonnet-4-5', small: 'anthropic/claude-haiku-4-5' })
- Session persistence uses 'provider/modelId' string format with optional role field
