* feat(web): show hidden directories in workspace browser
Add optional includeHidden param to the machine list-directory RPC so the
WorkspaceBrowser can toggle hidden (dot-prefixed) entries. Default remains
filtered for backward compatibility; the toggle persists via localStorage.
* fix(web): disable show-hidden toggle while directory loading
Prevent overlapping list-directory requests with opposite includeHidden
values; the toggle is now disabled while a directory load is active.
* 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.

* test: reproduce issue #898 (Codex fast mode service tier)
* fix(codex): add Fast mode (service tier) toggle and /fast command (closes#898)
* feat(codex+web): Fast mode UI toggle with full persistence
Wires the Codex Fast mode (service tier) end-to-end so it can be toggled
from the web composer and survives reload/handoff:
- shared: serviceTier on Session/SessionPatch, session-alive payload,
resume target, and a SessionServiceTierRequest schema
- cli: AgentSessionBase carries serviceTier through keepAlive; runCodex
syncs it to the session instance
- hub: service_tier column (schema v10 + migration), store setter,
sessionCache + syncEngine plumbing, POST /sessions/:id/service-tier
- web: api.setServiceTier + mutation, a Fast/Standard toggle in the
composer settings (gated to Codex GPT-5.5/5.4), and StatusBar now
reflects the real tier instead of the effort heuristic
Refs #898
* fix(codex): preserve unset/persisted service tier on startup keepalive
Addresses HAPI Bot [Major] on PR #904: applyCurrentConfigToSession ran
setServiceTier(currentServiceTier ?? null) on wrapper-ready, collapsing the
untouched `undefined` state into explicit Standard. The immediate
setCollaborationMode keepalive then persisted serviceTier: null, silently
downgrading resumed Fast sessions and disabling account-default Fast.
- Seed currentServiceTier from the persisted session (sessionInfo.serviceTier),
so a resumed Fast thread keeps running Fast.
- Only call setServiceTier when the tier is explicit (!== undefined), preserving
the three-state omit semantics at the keepalive boundary.
- Add regression tests: persisted Fast is re-asserted; untouched omits the tier.
* feat(codex+web): gate Fast toggle on catalog-advertised service tier
The Fast toggle was gated on a model-name regex (gpt-5.5/5.4), which still
showed a no-op control to API-key users — Fast credits only apply with
ChatGPT login. Codex's model/list catalog advertises the service tiers
actually available for each model in the current auth/plan context, so gate
on that instead:
- cli: capture serviceTiers (ids) per model in ModelListItem + normalizeModel
- shared: CodexModelSummary.serviceTiers (flows through the existing
getSessionCodexModels pass-through; no hub change needed)
- web: codexModelAdvertisesFastTier(sessionModel, models) replaces the regex;
SessionChat gates the toggle on it (hidden while the catalog is
loading/errored). The toggle now only appears when toggling it will
actually take effect.
Refs #898
* fix(codex): make explicit Standard service tier sticky across resume
Addresses HAPI Bot [Major] (round 2): a single persisted null conflated
"untouched" with "explicit Standard". A user who turned Fast off persisted
null, but startup mapped null -> undefined (untouched) and omitted serviceTier,
so an account/thread-default Fast could silently return after restart/resume.
Introduce a distinct stored representation:
- 'fast' / 'standard' are explicit user choices; null/undefined = untouched.
- Translate 'standard' -> Codex app-server serviceTier: null ONLY when building
thread/turn params (toAppServerServiceTier); untouched omits the field.
- /fast off now stores 'standard'; the web Standard option sends 'standard'.
- Tighten SessionServiceTierRequest to enum(['fast','standard']) so stray tier
strings are never forwarded.
Tests: sticky-Standard-on-resume regression; turn/thread params translate
'standard'->null and omit on untouched; hub route applies fast/standard and
rejects unsupported values + local sessions.
Refs #898
* fix(codex): recognize real Fast tier (id 'priority', name 'Fast') in catalog gate
Live E2E against an authed Codex session revealed the model catalog advertises
the Fast tier with id 'priority' and display name 'Fast' (not id 'fast'), so the
/fast/i gate — which only saw tier ids — wrongly hid the toggle for valid
ChatGPT users on gpt-5.5/gpt-5.4. Capture both the tier id and name as
lowercased tokens so the existing name-based match recognizes 'Fast'. The sent
value stays 'fast' (the documented service_tier value / raw additionalSpeedTiers
request tier). Verified end-to-end: gpt-5.5/gpt-5.4 gate on, gpt-5.4-mini off.
Refs #898
* fix(codex): preserve service tier across session resume
Resuming a Codex session spawns a fresh session (serviceTier null) and merges
the old one in. Unlike model/effort/permissionMode, serviceTier was neither
threaded through the resume spawn nor preserved in mergeSessionData, so a
resumed Fast (or explicit Standard) session silently reverted to the account
default.
Thread serviceTier through the spawn path like its siblings:
- hub: resumeSession passes session.serviceTier to spawnSession; rpcGateway +
syncEngine carry it in the spawn RPC payload; mergeSessionData preserves it
old->new (safety net).
- cli: SpawnSessionOptions.serviceTier; apiMachine forwards it; buildCliArgs
emits --service-tier for codex; the codex command parses it; runCodex seeds
currentServiceTier from the spawn override first (opts.serviceTier ??
sessionInfo.serviceTier), so a resumed thread immediately runs the right tier.
Verified end-to-end: set Fast -> kill process -> reopen -> resumed session (new
id) still runs Fast. Tests: buildCliArgs --service-tier (codex only), runCodex
spawn-override seed, mergeSessionData service-tier preservation.
Refs #898
* fix(codex): send advertised 'priority' tier id for Fast, not 'fast'
The model catalog advertises the Fast tier with request id 'priority' (display
name 'Fast'), and OpenAI docs confirm service_tier='fast' maps to the request
value 'priority'. The app-server serviceTier override is a raw request value
that does not validate unknown strings (a live probe accepted 'bogus-xyz'), so
sending 'fast' risks being silently ignored — no Fast applied.
Translate the stored 'fast' state to app-server 'priority' at the thread/turn
param boundary (toAppServerServiceTier); the stored/UI/command representation
stays 'fast'/'standard'. Verified live: a turn with serviceTier='priority' runs
and consumes the Fast-tier rate budget.
Addresses HAPI Bot [Major]. Refs #898
* fix(codex): validate --service-tier CLI value (fast|standard)
Addresses HAPI Bot [Minor]: the internal --service-tier spawn arg accepted any
non-empty string, unlike the web /service-tier enum, so a malformed value could
be seeded into currentServiceTier and persisted via keepalive. Parse it to
'fast'|'standard' and reject anything else, matching the web endpoint.
Refs #898
* refactor(opencode): declare ModelChange capability and add model field to OpencodeMode
Mark opencode flavor as supporting model change by adding Capabilities.ModelChange
to FLAVOR_CAPS.opencode. Add optional `model` field to OpencodeMode so the
set-session-config handler can carry a model alongside the existing permissionMode.
Pure structural change: no behavior change yet. The mid-session model change RPC
and UI wiring follow in subsequent commits, gated by this capability.
* feat(acp): branch setModel by flavor, capture session models metadata, expose getSessionModelsMetadata on AgentBackend interface
Adds an optional `flavor` argument to `AcpSdkBackend.setModel` so it can
dispatch the right `session/*` RPC for each agent flavor without changing
the call site Gemini already uses. Both Gemini and OpenCode wire to
`session/set_model`; the OpenCode response only carries `_meta.opencode`,
so the backend updates the cached `currentModelId` optimistically while
preserving the previously captured `availableModels`.
Captures `availableModels` and `currentModelId` from `session/new` /
`session/load` / `session/set_model` responses into per-session metadata,
exposed as `getSessionModelsMetadata(sessionId)` on the `AgentBackend`
interface so the hub can forward the snapshot to the web client.
* feat(opencode): accept model in set-session-config RPC and forward to launcher
Mirror the Gemini set-session-config handler so the web UI can change the
OpenCode model mid-session. Validates incoming model strings, persists null
("Default") for keepalive metadata, and pushes a keepAlive immediately so
the hub UI reflects the change without waiting for the next 2s tick.
Forward the model through opencodeLoop and into queued OpencodeMode entries
so the launcher can detect a per-batch model change. Add a setModel helper
on OpencodeSession to store the chosen model on the shared session base.
Wire --model up the runner path: parse --model <value> in commands/opencode.ts
and stop excluding opencode in buildCliArgs so the runner spawns OpenCode
with the user-selected initial model.
* feat(opencode): switch model mid-session via ACP RPC
Mirror the Gemini pattern from PR #543: when a user picks a different model
between turns, call backend.setModel with flavor='opencode' so the ACP backend
sends session/set_session_config_option (configId='model') to the running
OpenCode CLI. The next turn then runs against the new model.
The first batch on a fresh session seeds currentBackendModel without firing the
RPC — the OpenCode CLI was launched with that model via --model and there is
nothing to switch yet. If the running build does not implement the RPC we learn
that from the first method-not-found response, latch inline switching off, and
notify the user once. Other errors fall back to the previous model and surface
a one-line failure message.
* feat(hub): expose model selection and discovery for OpenCode sessions
Generalize the /sessions/:id/model guard via supportsModelChange so any flavor
that advertises the ModelChange capability becomes accepted automatically. This
piggybacks on the capability SSOT introduced in PR #400 and turns OpenCode on
without listing flavors inline.
Add a /sessions/:id/opencode-models endpoint that mirrors the existing
codex-models pattern. The endpoint forwards a per-session listOpencodeModels
RPC to the running OpenCode launcher, which returns the availableModels and
currentModelId metadata captured from the ACP session/new and
session/set_session_config_option responses. The web UI consumes this to
render the model dropdown without round-tripping ACP itself.
* feat(web): render OpenCode model dropdown in the chat composer
Mirror the Codex pattern in SessionChat: query /sessions/:id/opencode-models
via a new useOpencodeModels hook and feed the result into the composer's
availableModelOptions. The AssistantChat model dropdown now lists the user's
ollama / mlx / OpenCode Zen models with the same provider/model label that the
ACP server reports, so the picker matches the OpenCode TUI.
Stop falling back to the Claude composer model list when the flavor is
opencode and no custom options are supplied — that fallback briefly surfaced
unrelated Claude models in OpenCode sessions before the RPC response landed.
The NewSession flow keeps an empty MODEL_OPTIONS.opencode for now: model
discovery requires an active OpenCode ACP session, so the dropdown becomes
available once the session boots and stays empty (and hidden) at creation
time.
* feat(cli,hub): add cwd-based OpenCode model discovery RPC
Adds a short-lived `opencode acp` probe that runs `initialize` +
`session/new` against a target cwd to read the `availableModels` /
`currentModelId` snapshot, then tears the subprocess down. Results are
cached for 60s per cwd and concurrent probes coalesce into a single
spawn.
Exposes the probe through:
- `listOpencodeModelsForCwd` JSON-RPC handler on the CLI
- `RpcGateway.listOpencodeModelsForCwd` / `SyncEngine.listOpencodeModelsForCwd`
- `GET /api/machines/:id/opencode-models?cwd=...` on the hub
This lets the web NewSession form discover OpenCode models for a chosen
directory before any session is spawned.
* feat(web): add OpenCode model selector to NewSession with loading and default highlight
Adds a `OpencodeModelSelector` panel that the NewSession form swaps in
when the OpenCode flavor is selected. The panel:
- queries the new `GET /api/machines/:id/opencode-models?cwd=...` endpoint
via `useOpencodeModelsForCwd` (TanStack Query, 60s staleTime, no retry),
- shows a labelled spinner + skeleton rows while discovering,
- renders an inline error with a Retry button when probing fails,
- renders an empty-state message when the directory yields no models,
- highlights the OpenCode-reported `currentModelId` with a "Default" badge
and auto-selects it (or the first option) so the form has a sensible
value if the user hits Enter without scrolling.
Selection is reset whenever the agent / machine / directory changes so a
new probe can establish a fresh default. Directory input is wrapped in
`useDeferredValue` so per-keystroke edits do not spawn a fresh
`opencode acp` probe. The chosen model is forwarded on session spawn
via the existing OpenCode `model` parameter.
Adds en + zh-CN locale strings for the loading / failure / empty / retry
/ default-badge labels.
* fix(cli): guard /machines/:id/opencode-models handler with workspace root check
The machine-scoped `listOpencodeModelsForCwd` RPC handler was registered by
`registerCommonHandlers` without any workspace-root check, so a web client
could pass an arbitrary `cwd` and have the runner spawn an `opencode acp`
subprocess plus a `session/new` against that path. That broke runner
isolation, since peer machine-scoped handlers (`list-directory`,
`spawn-happy-session`) already enforce the configured workspace root.
Re-register the handler in `ApiMachineClient` so it reuses the existing
`resolveForWorkspaceCheck` (realpath-based, with missing-tail walking) and
`isWithinWorkspaceRoot` helpers before delegating to the lower-level probe.
The resolved cwd is forwarded down so symlinked-but-contained paths still
work, while traversal attempts are rejected with the same error shape the
peer handlers use. Added unit tests around the new dispatch path. Addresses
HAPI Bot review on PR #558.
* fix(web): gate opencode model discovery on cwd existence
The new-session form previously enabled `useOpencodeModelsForCwd` as
soon as the OpenCode agent, machine, and any non-empty directory string
were present. Because that hook calls `/machines/:id/opencode-models`
and the CLI handler starts an `opencode acp` probe for that cwd, normal
typing through partial paths could launch expensive 30s OpenCode
subprocesses for non-existent directories before the path-existence
result had validated the final cwd.
Reorder NewSession so `useMachinePathsExists` runs before
`useOpencodeModelsForCwd`, then gate the discovery hook on the
directory having been positively confirmed to exist
(`pathExistence[deferredDirectory] === true`). The decision is
factored into a small pure helper `shouldEnableOpencodeModelDiscovery`
so the contract can be unit-tested without provider scaffolding.
* fix(web): keep current opencode model on shortcut without dynamic options
`getNextModelForFlavor` is invoked by the global Ctrl/Cmd+M shortcut in
`HappyComposer`, which is now active for OpenCode sessions because the
agent backend declares the `ModelChange` capability. When the dynamic
OpenCode model list has not yet been loaded — e.g. the user presses the
shortcut before `/opencode-models` returns — the function received an
`undefined`/empty `customOptions` and fell through to the Claude preset
cycler, which would emit `sonnet`/`opus` for an OpenCode session. The
following turn then attempted `session/set_model` with a Claude model id
that no OpenCode provider can serve.
Add an `opencode` branch that returns the (normalized) current model
unchanged when no dynamic options are available, mirroring the existing
empty-list policy of `getModelOptionsForFlavor`. Unit tests cover the
undefined / empty / null-current-model variants and lock the
no-Claude-fallback contract. Addresses HAPI Bot review on PR #558.
* feat(web): add workspace browser for multi-directory navigation
Add /browse route with a folder browser that lets users navigate
filesystem directories on connected machines and launch sessions
from any folder. Supports saved workspace paths and direct path
input. The "Start Session" action pre-fills the NewSession form.
- CLI: register machine-level `list-directory` RPC handler
- Hub: add POST /machines/:id/list-directory route
- Web: add WorkspaceBrowser component with git repo detection
- Web: add /browse route with navigation from sessions sidebar
- Web: support initialDirectory/initialMachineId in NewSession

* feat: add --workspace-root opt-in scoping for /browse and session spawn
Adds a single new flag, \`--workspace-root <path>\` (with \`~\` / \`~/foo\`
expansion), on \`hapi runner start\` and \`hapi runner start-sync\`.
When set:
- The runner reports the path in machine metadata.
- The list-directory and spawn-session RPC handlers reject paths outside
the root, so the web UI can't escape the configured tree even if
someone crafts a request manually.
- The /browse page in the web UI auto-opens that root, restricts the
breadcrumb / go-up to its subtree, and shows directory entries with
git-repo annotations.
- The /sessions/new form keeps its existing free-text directory input
plus autocomplete + recent-paths chips, and gains a small "Browse"
button (next to the input) that opens /browse for picking a folder.
- Reconnect-time metadata sync ensures stale records get the field
filled in (or cleared when the flag is dropped on a later restart),
so the hub state matches the CLI's intent.
When unset:
- Runner behaves like the legacy hapi (no scoping, no browse feature).
- /browse renders an informative state pointing at the flag instead of
blocking the user.
- The /sessions/new form looks identical to the pre-change behavior;
the "Browse" button is hidden.
Includes a startup banner so \`runner start-sync\` no longer looks like
it hung, and surfaces the workspace-root sync result on stdout.

* fix(hub): preserve workspaceRoot when rehydrating machines from store
MachineCache.refreshMachine() rebuilt the metadata object from an
explicit field allowlist, so any field not in the list (including the
new workspaceRoot) was silently dropped on every read — even though it
was correctly written to the store.
Add workspaceRoot to the zod schema, the Machine interface, and the
hand-rolled projection.

* feat(web): friendlier empty state on /sessions
When there are zero sessions the page used to be a vast blank
rectangle with just the "0 sessions in 0 projects" caption. Render a
centered empty state instead: a calendar/agenda icon, a short heading
and hint, and two buttons — "Start a session" (→ /sessions/new) and
"Browse workspace" (→ /browse).
SessionList gains an optional onBrowse prop. Router wires it on the
sessions page so the secondary button resolves; other callers can leave
it unset to hide that button.

* docs: document --workspace-root flag in cli/README and root README
Add a short paragraph under "Runner management" in cli/README.md

the legacy behavior. Mention the workspace browser in the top-level
README's Features list.

* fix: address PR #526 review feedback
Three findings from the review bot:
1. [Major] Workspace-scope check was lexical only. With workspaceRoot
= /safe, a symlink such as /safe/out -> /etc would pass the relative-
path test and let list-directory / spawn-happy-session reach paths
outside the configured root. realpath the workspaceRoot at construction
time, and resolve every incoming path through realpath (walking up to
the nearest existing parent for spawn targets that haven't been
created yet) before the containment check.
2. [Minor] \`hapi runner start --workspace-root\` with no value used to
drop the flag silently and start the runner unscoped. Now treats a
missing or flag-shaped next argument as an error.
3. [Minor] /sessions/new's "Browse" button always opened /browse using
localStorage's last-used machine, ignoring the user's current
selection. NewSession already passes machineId in its callback;
forward it through the /browse search params and seed
WorkspaceBrowser with it.

* fix(cli): gate list-directory RPC behind --workspace-root opt-in
Without a configured workspaceRoot, isWithinWorkspaceRoot() returns
true unconditionally, leaving the new list-directory RPC able to
enumerate any path on the runner. The Web UI already hides Browse
for these machines, but the backend should enforce the opt-in too.
Refuse the RPC up front when no workspace root is configured.

* feat(hub,cli): forward permissionMode on session resume
When a session is resumed, the cached permissionMode is now forwarded
through the Hub → Runner → CLI pipeline via a new --permission-mode
flag. Previously the mode was lost on resume, resetting to 'default'.
Each CLI flavor validates the flag value against its own allowed
permission modes (e.g. CLAUDE_PERMISSION_MODES) and rejects unknown
values. The existing --yolo flag is preserved as a shorthand.
* refactor(cli): extract buildCliArgs from startRunner
Extract the CLI argument construction logic into a standalone
exported function so it can be unit-tested independently.
No behavior change.
* test(cli): add buildCliArgs unit tests for --permission-mode
Verify that the runner correctly forwards valid permission modes
via --permission-mode, rejects invalid values, and falls back to
--yolo when no permission mode is set.
* fix(cli): let --permission-mode take precedence over --yolo
When both flags are present, --permission-mode was silently
overwritten by a later --yolo. Guard legacy flag branches with
a hasExplicitPermissionMode check so the explicit flag wins.
* feat(cli): support extra headers for hub requests
* fix(types): normalize missing session fields to null
* refactor(cli): simplify socket extra headers config
* feat: improve spawn error handling and reporting across full stack
- Return error result instead of throwing in apiMachine spawn handler
- Add lastSpawnError field to RunnerState for persistent error tracking
- Add error awaiter system for early process exit/error detection before webhook
- Build detailed webhook failure messages with exit code, signal, and stderr tail
- Report spawn outcomes to hub via runner state updates
- Handle more spawn result types in rpcGateway with better error messages
- Display runner last spawn error in web UI (NewSession & SpawnSession)
- Extract shared formatRunnerSpawnError utility to avoid duplication

* fix(cli): narrow spawnResult type check to fix TS2339 error
Use `type === 'error'` instead of `type !== 'success'` to properly
narrow the discriminated union, allowing TypeScript to infer errorMessage.

Add ability to resume inactive sessions and automatically continue with new
session ID. Includes message merging for preserving conversation history,
UI improvements to allow sending during inactive state, and database schema
migration. close#87
Move socket-related type definitions and schemas from cli and server packages
into a shared @hapi/protocol package for centralized type management. This
includes migrating Update types, socket event interfaces (ClientToServerEvents,
ServerToClientEvents), and terminal payload schemas. Add strongly-typed socket
handlers that reference the protocol package instead of duplicating definitions.
Add a new ModelSelector component that allows users to choose specific model variants for different AI agents. This includes:
- ModelSelector UI component with agent-specific model options
- Model parameter propagation through API, RPC, and spawning layers
- Support for auto model selection (default behavior)
- Localization strings for English and Chinese
- Type definitions for model options per agent
Extract duplicate version acknowledgment logic from apiMachine and
apiSession into a reusable applyVersionedAck utility. This handles
success, version-mismatch, and error responses consistently with
customizable parsing and error handling via options object.
Restructure CLI entry point and RPC handler registration to improve maintainability:
- Introduce command registry pattern with CommandDefinition interface for consistent command structure
- Extract individual command modules (claude, codex, daemon, doctor, gemini, auth, connect, etc.)
- Move RPC handlers into separate feature modules (bash, files, git, directories, ripgrep, difftastic, slashCommands)
- Create shared RPC types and response helpers (rpcTypes.ts, rpcResponses.ts)
- Move SpawnSessionOptions and SpawnSessionResult to rpcTypes for proper type organization
- Simplify index.ts to minimal entrypoint using command registry
- Update imports in apiMachine.ts and daemon/run.ts to use rpcTypes module
This enables:
- Better code organization by feature/command
- Easier testing of individual commands
- Safer RPC handler registration without side effects
- Clearer separation of concerns between routing and business logic
Implement namespace support across sessions, machines, and users for multi-user server deployments. Add access control with specific error reasons (namespace-missing, access-denied, not-found) and database schema updates with namespace columns and indexes.
Implement comprehensive worktree session support allowing users to spawn sessions in temporary git worktrees. Includes backend worktree management, full-stack integration, and refined UI for session type selection.
Backend:
- Add worktree creation/removal utilities with branch management
- Track worktree metadata (basePath, branch, name, path) in session metadata
- Automatic cleanup of worktrees when sessions fail or exit
- Enhanced error handling with stderr tail logging
UI improvements:
- Redesign session type toggle with improved alignment and spacing
- Move worktree description inline with label for cleaner layout
- Add branch name input field that appears when worktree mode selected
- Auto-focus on worktree input when switching modes
- Reduce gap between radio options from gap-3 to gap-1.5
- Update descriptive text and placeholders for clarity
Integration:
- Thread worktree parameters through API client, RPC handlers, and daemon
- Add worktreeEnv utility to read worktree info from environment
- Update session spawning to support both simple and worktree modes
This commit rebrands the project from "Happy" to "HAPI" throughout the codebase, including documentation, comments, logs, and tool references. It also adds comprehensive README files for the server and web components, clarifies the monorepo structure in AGENTS.md and root README.md, and removes the outdated roadmap.md file.
Changes include:
- Rebrand references from Happy to HAPI in CLI, server, and web components
- MCP tool names updated from mcp__happy__ to mcp__hapi__
- Process/service names updated consistently
- New server/README.md with deployment and configuration guide
- New web/README.md with stack and development instructions
- Updated root README.md with quickstart guide
- Updated AGENTS.md with cleaner structure documentation
- Removed cli/roadmap.md (now superseded by documentation)
