* feat: add message-level conversation fork and rewind
Expose native Codex/Grok/Claude history controls through hub REST+RPC and web ConfirmDialog actions, without file rewind or composed forks. Also reconcile the duplicate hub V14→V15 migration so typecheck can pass.

* fix: hydrate fork transcript and consume Claude --fork-session
Forked HAPI children now copy the source transcript prefix so navigation is not a blank thread, and Claude drops --fork-session after the first launch so relaunches do not branch again.

* fix: harden fork/rewind concurrency and durable history points
Skip pending scheduled rows when hydrating fork transcripts, serialize fork/rewind per session, and persist conversation history points/indexes across existing-session bootstrap and Grok relaunches.

* fix: close remaining fork/rewind races and UI anchoring
Block sends and scheduled maturation while history actions run, order fork prefixes by invocation time, inherit history locators into children, and only offer Fork current on the live tail boundary.

* fix: address remaining fork/rewind bot findings
Materialize Claude --fork-session before the first child prompt, validate
HAPI history boundaries before native RPC, expose forkCurrent on a latest
user boundary, fully demote unsupported conversationHistory capabilities,
and fix the truncate test setup order.

* fix: align fork-current ids and Claude fork bootstrap
Compare the latest fork boundary in assistant-ui threadMessageId space,
spawn Claude forks with the persisted session mode, and preserve
forkedFrom across existing-session bootstrap.

* fix: close fork/rewind consistency holes at the contract layer
Hold the source history lock until Claude child binds a distinct native
id, persist Codex localId→turnId locators, and mark/block diverged
sessions when native rewind outruns HAPI truncate.

* fix: use Codex stable lastTurnId for historical fork
Map HAPI's exclusive boundary to the previous turn's inclusive
lastTurnId so native fork context matches the hydrated transcript.
Co-authored-by: Cursor <cursoragent@cursor.com>
* fix: require exact Grok native resume for fork children
Reject newSession fallback when forkedFrom is set, and keep the hub
history lock until the child binds the forked grokSessionId.
Co-authored-by: Cursor <cursoragent@cursor.com>
* fix: kill active fork children before failed-fork cleanup
Bind/readiness failures can leave the child process running; deleteSession
rejects active rows, so terminate first then remove the HAPI session.
Co-authored-by: Cursor <cursoragent@cursor.com>
* fix: close remaining fork lock, hydrate, and todos gaps
Reject mode switches during history actions, batch-copy fork
transcripts in one SQLite transaction, and rebuild todos after
fork hydrate / rewind truncate.
Co-authored-by: Cursor <cursoragent@cursor.com>
* fix: allow Codex historical fork before the first turn
Use experimental beforeTurnId when there is no previous turn for the
stable inclusive lastTurnId boundary.
Co-authored-by: Cursor <cursoragent@cursor.com>
* fix: mark Grok history busy immediately after dequeue
Hub idle checks clear once messages-consumed fires; hold the busy flag
across permission sync and rewind-points lookup before prompt starts.

* fix: encode copied conversation history content
* fix(web): hide local conversation history actions
* style(codex): remove trailing whitespace
* fix(fork): preserve children when cleanup is unconfirmed
* fix(history): confirm cleanup and guard rewind divergence
* fix(history): probe capabilities before advertising

On Windows, spawning Claude with shell: true causes the process to
exit immediately with code 1. This happens because shell: true invokes
cmd.exe /c claude <args>, and cmd.exe's PATH resolution differs from
direct process creation, leading to environment inconsistencies.
This fix:
- Adds findWindowsClaudePath() to locate claude.exe absolute path
- Changes spawn to use absolute path with shell: false on Windows
- Maintains Unix behavior (command name works fine with shell: false)
- Adds HAPI_CLAUDE_PATH env var for user override
Tested on Windows 11 with Claude Code v2.1.29 and hapi v0.15.0.

Simplify environment handling by removing the getCleanEnv() function that was
filtering out local node_modules/.bin paths. Running from home directory is
sufficient to avoid local cwd side effects.
Consolidate process lifecycle management (kill, check alive) into a new
utility module with proper Windows/Unix handling, replacing scattered
process.kill() calls with consistent async APIs.
Remove support for custom executable paths and bundled Claude versions, including
deprecated environment variables HAPI_USE_BUNDLED_CLAUDE and HAPI_USE_GLOBAL_CLAUDE.
This simplifies the codebase to rely only on the global Claude CLI installation.
Updates Claude Code spawning logic to remove special handling for .js/.cjs files,
adds configurable BUN_BE_BUN environment variable handling, and streamlines path
resolution to throw an error when Claude Code CLI is not found on PATH.
Adds a dedicated hook server infrastructure to receive Claude SessionStart
notifications. This allows the CLI to track session ID changes (new sessions,
resume, compact, fork, etc.) without relying on file watchers.
Changes:
- Add SessionFound callback system to AgentSessionBase for session tracking
- Create hook server that listens for POST requests from Claude's hooks
- Generate temporary settings files with hook command configuration
- Implement session hook forwarder CLI command to relay hook data
- Integrate hook server into runClaude with proper cleanup
- Pass hookSettingsPath through local and remote execution paths
- Update SDK query builder to support --settings flag
Enables building hapi as standalone Bun-compiled executables for macOS,
Linux, and Windows (x64/arm64). Adds build script, bootstrap entry point,
runtime asset management, and automatic deployment of bundled tools
(ripgrep, difftastic). Includes MCP stdio bridge support and proper
environment handling for compiled binaries. Updates documentation with
build and installation instructions for single executable distribution.
