- Parallelized `collectSessionsFromFiles` via strided workers sized by file count and CPU parallelism, reducing large-list latency.
- Read only a fixed 1024-byte prefix per session file in `collectSessionFromFile`, avoiding full-file scans.
- Added partial-prefix fallbacks to extract session title and first user message when JSONL parsing is incomplete.
- Updated SessionManager.listAll to retrieve session files with Bun.Glob.scan instead of scanSync.
- Awaited the async glob scan results via Array.fromAsync before collecting session metadata.
When persist writes race with test-level tempDir cleanup (e.g. in agent-session-auto-compaction-queue.test.ts), fs.rename can fail with ENOENT during the atomic swap inside #writeEntriesAtomically. The error is already routed through #persistChain so #persistError surfaces it to future persist calls, but the awaited rejection returned by #queuePersistTask was bubbling out of the fire-and-forget callers (#rewriteFile path and the incremental writer path) and Bun's test runner reported it as an 'Unhandled error between tests' even though the test itself passed. Attach a silent .catch on both void paths so the rejection is considered handled at the callsite while the persistChain retains the error state.
- 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.
- Add /rename <title> slash command to set an explicit session name,
updating the session header, terminal tab title, and status line
- Add session_name status segment: displays the session name on the
right side of the status bar with a stable djb2-hash-derived accent
color unique to each name; shown in all presets when a name is set
- Add setSessionName source tracking ('user' vs 'auto'): auto-generated
titles are silently ignored once the user has explicitly set a name,
preventing the async title generation from overwriting a /rename
- Sanitize session names at storage time: strip C0/C1 control characters
(including ANSI ESC) via static #sanitizeName before storing, blocking
escape sequence injection into the TUI, terminal title, and session file
- Extend sanitizeStatusText to cover the full C0/C1 range as
defense-in-depth (superset of the previous \r\n\t-only strip)
- Use stored (sanitized) name for showStatus message and terminal title
in handleRenameCommand, not the raw user input
- Guard terminal title update in auto-title path via titleSource === 'auto'
so a user rename is never overwritten by a late-resolving LLM call
- Reset #titleSource in #newSessionSync so each new session starts fresh
- Thread source parameter through AgentSession.setSessionName wrapper;
extension API and RPC set_session_name treated as 'user' intent
Closes#658

- 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.
- Changed SessionManager.list() signature to require cwd parameter as first argument with sessionDir now optional.
- Implemented multi-root session migration support by replacing global migration state with per-root tracking and extracting session directory encoding logic.
- Added resolveManagedSessionRoot() function to determine if session directory is managed and extract its root.
- Added symlink and path alias resolution to session directory handling for consistent behavior across aliased home and temp directories.
- Improved status line path display to strip display roots using canonical path resolution, correctly handling symlink-equivalent directory aliases.
- 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 automatic migration of legacy absolute-path session directories with double-dash format to new canonical locations.
- Enhanced session directory encoding to use `-tmp-` prefix for temporary directories instead of legacy double-dash format for improved clarity.
- Extracted session directory migration logic into reusable helper functions for better maintainability.
- Updated test setup to mock home directory and verify session migration behavior with temporary paths.
- Added `attribution` option to `PromptOptions` for controlling billing and initiator attribution.

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
* feat(utils): full XDG Base Directory support for all path helpers
Implement XDG-first resolution across all omp path helpers, extend the
migration command to cover every data/state/cache location, and fix
five data-safety issues found in review.
dirs.ts:
- Add getXdgCachePath() helper ($XDG_CACHE_HOME/omp/<subpath>)
- Add isDefaultAgentDir() helper: XDG lookup is only valid when the
resolved agentDir equals the process default (~/.omp/agent); custom
profiles set via PI_CODING_AGENT_DIR or setAgentDir() are never
silently redirected to the global XDG database
- Update 15 functions to XDG-first resolution:
data: getPluginsDir, getRemoteDir, getRemoteHostDir, getPythonEnvDir,
getWorktreeBaseDir
state: getReportsDir, getSshControlDir, getCrashLogPath, getDebugLogPath
cache: getPuppeteerDir, getGpuCachePath, getNativesDir
- Guard XDG lookup with isDefaultAgentDir(agentDir ?? getAgentDir()) in
all 9 agent-subdir helpers so that callers passing the global default
agentDir still resolve to the migrated XDG location, while callers
passing a non-default agentDir or running under a custom profile via
setAgentDir() bypass XDG entirely
- Plugin-derived helpers delegate to getPluginsDir() and follow XDG
resolution automatically
migrate-xdg.ts:
- Add getXdgCacheHome() helper
- Extend MigrationItem.category to include 'cache'
- Add 12 new migration entries: reports, plugins, remote, ssh-control,
remote-host, python-env, puppeteer, wt, gpu_cache.json, natives,
omp-crash.log, omp-debug.log
- Refuse to run when PI_CODING_AGENT_DIR points to a non-default
profile: migration only makes sense for the default ~/.omp/agent tree
- copyDirectory returns skipped source paths (target existed, non-force)
- verifyIntegrity: remove size-mismatch early-return that masked stale
targets as successful copies
- executeMigration: delete only entries that were actually copied;
use rmdir on source dir so it is removed only when empty, preserving
any skipped files for a subsequent --force run
- executeMigration: rename partial target to <target>.bak on integrity
failure instead of deleting; preserves pre-existing user data while
preventing getXdgDataPath from treating the partial tree as
authoritative; source remains intact for re-copy on next run
test isolation:
- Set XDG_DATA_HOME/XDG_STATE_HOME to non-existent paths in
memories-runtime.test.ts beforeEach/afterEach to prevent
getXdgDataPath/getXdgStatePath from resolving to real user data
* fix(utils,coding-agent): fix XDG support issues
dirs.ts:
- Refactor path resolution into DirResolver class. XDG base dirs are
resolved once at construction from env vars (Linux only, no
existsSync). setAgentDir creates a fresh instance, naturally
invalidating all cached paths and recomputing isDefaultProfile.
- getRootSubdir/agentSubdir accept optional XdgCategory parameter;
when set, the XDG base replaces the config root. Every accessor
is a one-liner delegate.
- Non-Linux platforms: XDG fields are null, zero overhead. No
filesystem probing, no string comparisons on the hot path.
- Config-only subdirs (themes, tools, commands, prompts, modules)
have no XDG category — they stay under the config root.
- Remove `import { env } from 'bun'`, use process.env consistently.
- Restore JSDoc comments to document actual defaults (~/.omp/...).
migrate-xdg.ts:
- Gate migrateToXdg on Linux — exits with clear error on other
platforms.
- Fix data loss bug: verifyIntegrity now accepts a Set of skipped
paths and skips verification for files that were intentionally not
copied (pre-existing at target in non-force mode).
- Fix nested directory source deletion: recursive removeSourceEntries
walks the tree and only deletes files not in the skipped set.
- Remove dead _sourcePath variable and unused force parameter from
verifyIntegrity.
- Remove `import { env } from 'bun'`, use process.env consistently.
logger.ts:
- Revert JSDoc to document ~/.omp/logs/ as default.
oauth.ts:
- Replace direct getAgentSubdir call with getTestAuthPath().
CHANGELOG.md:
- Merge duplicate section headers under [Unreleased].
- Add missing blank line before [13.11.1].

- Added `close()` method to SessionManager and AuthStorage for proper resource cleanup and finalization of prepared statements.
- Added `initiatorOverride` option support in OpenAI and Anthropic providers for message attribution control.
- Fixed resource leaks in RpcClient timeout handling by centralizing timeout creation with unref() and adding explicit clearTimeout() calls.
- Fixed AgentSession disposal to call SessionManager's `close()` method for guaranteed resource cleanup instead of fallback flush.
- Updated all test suites to properly dispose AuthStorage instances in cleanup hooks to prevent resource leaks between tests.
writeTerminalBreadcrumb used void Bun.write() — discarding the promise.
When parallel tasks write the same breadcrumb file concurrently on
Windows, Bun.write fails with EBUSY. The discarded promise rejects
unhandled, crashing the process.
Replace void with .catch(() => {}) to properly swallow best-effort
failures.

* fix: strip invalid thinking signatures from aborted/errored messages
When a stream is interrupted mid-response, thinking blocks may have
empty or partial cryptographic signatures. These get persisted to
session history and sent on the next API call, causing:
'Invalid signature in thinking block'
transformMessages() now detects aborted/errored assistant messages and
clears thinkingSignature fields so they are treated as unsigned thinking
(converted to text by the serializer).
Also protect truncateForPersistence from corrupting signatures — clear
them entirely instead of truncating, since a partial signature is always
invalid.
* fix: disable thinking when tool_choice forces tool use on Bedrock
Bedrock rejects requests that combine extended thinking with forced
tool_choice (any or specific tool). The Anthropic provider already had
a guard (disableThinkingIfToolChoiceForced) but the Bedrock provider
was missing the equivalent check.
Also fix thinking block serialization: when a thinking block has no
valid signature (e.g., from an aborted stream), convert it to plain
text instead of sending it as reasoningContent without a signature.
The API requires the signature field on all reasoning blocks for models
that support it.
Add thinking block diagnostics to error messages for signature/thinking
related failures to aid debugging.
