7a2a8e09bc feat(agent): add Hermes as 4th ACPX adapter (in-VM container, BrowserOS-managed providers) (#956)
* feat(agent): add Hermes as a 4th ACPX adapter (Phase A)

Adds Hermes Agent (NousResearch/hermes-agent) as a host-process ACPX
adapter, mirroring the Claude Code pattern.

- agent-types.ts: extend AgentAdapter union with 'hermes'
- agent-catalog.ts: add Hermes catalog entry
- lib/agents/hermes/prepare.ts (new): minimal prepare using prepareBrowserosManagedContext
- acpx-agent-adapter.ts: register the adapter
- acpx-runtime.ts: add 'hermes' branch returning 'hermes acp' (host)
- AdapterIcon.tsx: add Hermes icon
- db schema + supporting frontend types/literals updated for the new adapter

Phase A scope: host-process only. Phase A.5 swaps to nerdctl exec
into a Hermes container.

OpenClaw is untouched. Verified by all 6 POC spikes
(plans/features/claude-browseros-hermes-poc/findings.md).

* fix(agent): address Hermes adapter review issues

- NewAgentDialog: add 'hermes' to onValueChange guard so the dropdown
  option actually wires through onRuntimeChange/onHarnessAdapterChange
  (was a no-op before — selecting Hermes silently kept previous value)
- tests/acpx-runtime: add coverage for the new 'hermes' registry branch
- tests/acpx-agent-adapter: fold hermes prepare test into existing file,
  matching the pattern used for claude/codex/openclaw
- Delete tests/lib/agents/hermes-prepare.test.ts (now redundant)
- Reconcile install-mechanism comment between acpx-runtime.ts and
  agent-catalog.ts

* fix(agent): make Hermes adapter actually work end-to-end

Two surgical fixes uncovered while running the Phase A smoke test
through the BrowserOS chat HTTP API:

1. lib/agents/hermes/prepare.ts — seed per-agent HERMES_HOME from
   the user's global ~/.hermes/ on first use. ensureAgentHome only
   writes SOUL.md and MEMORY.md; without seeding config.yaml, .env,
   and auth.json, hermes acp comes up unconfigured and either hangs
   or errors with "No LLM provider configured." Copy is idempotent
   (skip if dest exists) so subsequent prepare calls don't clobber
   per-agent edits.

2. lib/agents/acpx-runtime.ts — wrap the hermes spawn in
   `bash -c "exec hermes acp | tee /dev/null"` to bridge Bun's
   socketpair-based child stdio with Python's asyncio.connect_write_pipe
   (which only drains correctly to a real pipe(2)). Without it, hermes'
   stdout never reaches the harness — verified by inspecting hermes
   process FDs: Bun gives the child unix sockets, asyncio queues writes
   that never become readable on Bun's end. With tee in the middle,
   hermes writes to a real pipe and tee bridges the bytes through the
   socket. Verified 2026-05-06 against hermes-agent 0.12.0 on macOS
   arm64 + Bun 1.3.6.

Smoke-test result with both fixes:
- ACP session created end-to-end
- BrowserOS MCP wired (96 browser tools registered with hermes)
- Reasoning + text streamed back through /agents/:id/sidepanel/chat
- Final stream: text-delta "PONG", finishReason "stop"

Updates the existing acpx-runtime test to assert the new spawn shape
(bash -c, tee /dev/null bridge) so the workaround can't silently regress.

* feat(agent): run Hermes adapter in Lima container (Phase A.5)

Move Hermes ACPX adapter from host-process spawn to running inside
docker.io/nousresearch/hermes-agent:v2026.4.30 in the existing
BrowserOS Lima VM, mirroring the OpenClaw container pattern.

Container lifecycle (api/services/hermes/hermes-container.ts):
- prewarm: ensure VM ready, pull image (or skip if already in
  containerd), start an idle container with /bin/sh -c "exec sleep
  infinity" so the harness can nerdctl exec into it per turn
- Tini bypassed — tini 0.19.0 in upstream image getopt-parses any
  -x token even after PROGRAM, breaking /bin/sh -c
- --add-host host.containers.internal:<vm-gateway> so hermes inside
  the container can reach the BrowserOS HTTP MCP endpoint
- Bind-mount <browserosDir>/vm/hermes/harness onto /data/agents/harness
  so per-agent HERMES_HOME dirs are visible to the container

Spawn (acpx-runtime.ts):
- HermesGatewayAccessor interface (mirrors OpenclawGatewayAccessor)
- resolveHermesAcpCommand builds:
  env LIMA_HOME=... limactl shell --workdir / browseros-vm --
    nerdctl exec -i -e PYTHONUNBUFFERED=1 -e HERMES_HOME=... <container>
    /opt/hermes/.venv/bin/hermes acp
- Absolute path /opt/hermes/.venv/bin/hermes (not bare "hermes") since
  upstream image's PATH is set by its entrypoint script which we
  override to keep the container idle
- Falls back to host-process spawn when no HermesGatewayAccessor wired
  (test path / dev fallback)
- Drops the host-mode bash+tee workaround — limactl/SSH/nerdctl pipe
  chain is sufficient for asyncio's pipe writer

MCP wiring:
- New PreparedAcpxAgentContext.browserosMcpHost field threads through
  prepare → getRuntime → createBrowserosMcpServers
- Hermes prepare sets browserosMcpHost='host.containers.internal' so
  the URL injected into newSession.mcpServers resolves from inside
  the container; other adapters keep '127.0.0.1' default

Per-agent home (lib/agents/hermes/prepare.ts):
- HERMES_HOME points at /data/agents/harness/<agentId>/home (in-container)
- Host-side seedHermesHomeFromGlobal still copies ~/.hermes/{config.yaml,
  .env, auth.json} into the per-agent home; the volume mount makes them
  visible inside the container
- New api/services/hermes/hermes-paths.ts holds host/container path helpers

End-to-end smoke tests against the dev server (clean Lima state):
- Plain text: PONG round-trip via /sidepanel/chat ✓
- Multi-turn context: RUBY-7421 stored + recalled ✓
- Multi-agent isolation: agent 2 doesn't see agent 1's secret ✓
- MCP tool execution: mcp_browseros_browseros_info fires ✓
- Image attachment via /chat: model identifies "Red" from a 128x128 PNG ✓
- Concurrent turns + 409 attachUrl: full attach streams the in-flight
  Pacific Ocean essay turn cleanly ✓
- Cancel midstream + recovery turn: ALIVE response ✓
- Persistence across server restart: agents survive ✓

* feat(agent): per-agent provider/key for Hermes adapter

Lets users create multiple Hermes agents each with its own provider,
model, and API key. NewAgentDialog now shows provider/model/key fields
inline when 'Hermes' is selected. On submit, the harness writes the
per-agent <browserosDir>/vm/hermes/harness/<agentId>/home/{config.yaml,
.env} directly so the agent has the right config from turn 1 — no
dependency on the user having run `hermes setup` outside BrowserOS.

The existing seedHermesHomeFromGlobal flow remains as a fallback for
agents created without provider fields (e.g. via direct API or with
an existing ~/.hermes/ install).

Backend:
- shared/constants/hermes.ts: HERMES_SUPPORTED_PROVIDERS registry
  (openrouter, anthropic, openai, custom — bedrock follow-up)
- api/services/hermes/hermes-paths.ts: writeHermesPerAgentProvider
- agent-harness-service: writes per-agent config.yaml + .env in
  createAgent when adapter=hermes and apiKey present
- routes/agents.ts: relax modelId catalog validation for adapter=hermes
  (catalog has empty models[] by design; per-agent modelId is free-form)
- tests/agent-harness-service: cover write + skip paths

Frontend:
- HermesProviderFields.tsx (new): provider dropdown, model field, API
  key + optional baseUrl when provider=custom
- NewAgentDialog: render the new fields when adapter=hermes
- agents-page-actions: thread fields through createHarnessAgent
- AgentsPage / agent-harness-types: minor pass-through edits

Smoke-tested end-to-end against the dev server (clean Hermes per-agent
home, no ~/.hermes/ seed): create agent with apiKey + modelId, files
written at the per-agent path with mode 0600, first chat returns the
expected response, all without touching ~/.hermes/.

* feat(agent): source Hermes provider config from BrowserOS LLM providers

Replace the Hermes-specific provider/model/API-key form in New Agent
with a chooser that pulls from the same global LLM providers OpenClaw
uses (Settings → BrowserOS AI). Backend rejects creation with a 400
when the selected provider is missing required fields (apiKey, modelId,
plus baseUrl for openai-compatible) or is not in the Hermes-supported
set; the ~/.hermes/ fallback is removed so Hermes agents always carry
their own per-agent config.

0c84547e8f feat(agents): migrate OpenClaw chat onto the unified harness/ACP path (#859)
* chore(acp): smoke-test ACP capabilities against running gateway

Adds apps/server/scripts/acp-smoke.ts which spawns `openclaw acp`
inside the gateway container and exercises every method we plan to
depend on: initialize, newSession, prompt (text + image), cancel,
listSessions, loadSession.

SDK pinned to 0.19.1 (Bun's minimum-release-age policy blocks 0.20+
which were released < 7 days ago).

Findings (full notes in plan outcomes):
- promptCapabilities advertises image:true but the model does NOT see
  image bytes — silently dropped at the bridge.
- sessionCapabilities advertises {list:{}} but session/list throws
  "Method not found": stale capability advertising.
- loadSession works; replays user/assistant/thought text and
  session_info/usage/commands updates. No tool_call replay, as
  documented.
- cancel works end-to-end: stopReason=cancelled.
- closeSession/resumeSession are not on ClientSideConnection in
  0.19.1; kill child to close, use loadSession for rebind.

Plan revisions triggered by spike are recorded in
plans/browseros-ai/BrowserOS/features/2026-04-28-2310-claude-code-acp-implementation-roadmap.md.

* chore(acp): re-run smoke on SDK 0.21.0 and add mode/config/auth scenarios

After bypassing Bun's minimum-release-age and upgrading the SDK to
0.21.0, restore the previously-skipped resume/close paths and add
three new scenarios: mode (setSessionMode), config (setSessionConfigOption,
correct configId field), and auth (authenticate noop).

Findings, all bridge-side (independent of SDK):
- session/list, session/resume, session/close all throw -32601 on
  OpenClaw 2026.4.12 — capability advertising is stale.
- Image content blocks silently dropped; model never sees the bytes.
- setSessionMode and setSessionConfigOption work; latter requires
  `configId` (not `optionId`) per the schema.
- loadSession replays user/assistant/thought text + session_info +
  usage + available_commands; no tool_call replay (documented).
- authenticate is a noop on OpenClaw (no authMethods advertised).

Plan outcomes updated with full method-support matrix.

* chore(deps): promote @agentclientprotocol/sdk to a runtime dependency

The smoke script in apps/server/scripts/acp-smoke.ts used the SDK as
devDependency. The upcoming ACP bridge (apps/server/src/api/services/acp/)
needs it at runtime, not just for tooling. Move the entry from
devDependencies to dependencies, alphabetically first under @a*.

Pinned to 0.21.0 — same version the smoke script validated against.
README gains a small Dependencies note pointing at the future bridge
location.

No code changes yet. The bridge wiring lands in subsequent commits.

* fix(openclaw): wire LlmProvider.supportsImages through to OpenClaw model config

When BrowserOS sets up a custom OpenAI-compat provider on the gateway,
the agent UI's "Supports Image" flag (LlmProviderConfig.supportsImages)
was being dropped on the floor. As a result the persisted model entry
had no `input` field, OpenClaw defaulted it to ['text'], and image_url
content parts were silently stripped before the model saw them.

Fix:
- Extend OpenClawSetupInput / OpenClawAgentMutationInput on the agent
  side (useOpenClaw.ts) and the route body schema + SetupInput +
  createAgent input on the server side with `supportsImages?: boolean`.
- AgentsPage forwards `llmOption?.supportsImages` from the selected
  LlmProviderConfig in both handleSetup and handleCreate.
- provider-map.resolveSupportedOpenClawProvider emits
  `input: ['text', 'image']` on the model entry when the flag is
  truthy; otherwise emits the explicit `['text']` so the value is
  always pinned (avoids relying on OpenClaw's implicit default).
- applyBrowserosConfig adds `tools.media.image.enabled = true` to the
  bootstrap batch so the gateway's image-understanding pipeline is
  always wired up — per-model `input` still gates which models see
  images, this just enables the global path.

ACP image content blocks are still dropped by the OpenClaw bridge —
that's a separate bridge bug, not addressed here. This commit
restores image support for the OpenAI-compat /v1/chat/completions
path that the upcoming ACP chat panel will use as a carve-out for
image-bearing prompts.

Existing custom-provider configs are NOT auto-migrated; users will
re-acquire image support either by re-running setup or by editing
their model entries' `input` field manually. A migration pass for
legacy installs is not in scope for this commit because the
"supportsImages" intent isn't recoverable from the persisted config
alone — the source of truth is the LlmProvider record on the agent
side.

* feat(agents): add OpenClaw to AgentAdapter union and catalog

Extends AgentAdapter to 'claude' | 'codex' | 'openclaw' and adds the
OpenClaw entry to AGENT_ADAPTER_CATALOG. The new entry has:

- defaultModelId: 'default' — OpenClaw's ACP bridge does not surface
  per-session model selection (verified during the ACP spike), so
  models live in the OpenClawService config, not in the adapter
  catalog. AgentDefinition.modelId carries the gateway-side model
  name for display only.
- models: [] — empty list signals "no per-session model picker" in
  the UI; isSupportedAgentModel('openclaw', undefined|'default')
  returns true via the existing fallback path.
- reasoningEfforts mirror OpenClaw's session-level `thought_level`
  config option (off / minimal / low / medium / high / adaptive).

Also extends:
- isAgentAdapter type guard recognizes 'openclaw'
- HarnessAgentAdapter union on the extension side
- agents.test.ts createAgent fake type
- agent-catalog.test.ts asserts on the new entry, empty model list
  passthrough behavior, and OpenClaw's reasoning effort set

Lockfile delta is the workspace SDK pin reconciling 0.20.0 (taken
from dev's lock) up to our package.json's 0.21.0 (added in
c1d987ea). acpx still uses 0.20.0 transitively — both are present.

No runtime wiring yet — the registry override and AcpxRuntime
plumbing land in subsequent commits.

* feat(agents): plumb OpenClaw gateway accessors into AcpxRuntime

Adds an optional `openclawGateway` accessor to AcpxRuntime so the
upcoming registry override (Step 4) can spawn `openclaw acp` inside
the gateway container with the right port, token, and container/VM
identity. All accessors are getter-shaped so values stay live across
gateway restarts (port can change, token can rotate).

The accessor is threaded:
  server.ts → createAgentRoutes → AgentHarnessService → AcpxRuntime
                            ↘ sidepanel lazy AcpxRuntime

Also adds OpenClawService.getGatewayToken() returning the in-memory
token string. We pass it via OPENCLAW_GATEWAY_TOKEN env var on the
spawn (per OpenClaw's documented env-var precedence) instead of via
`--token` flag (which leaks to ps aux) or `--token-file` path (no
discrete token file lives inside the container — the token is nested
inside openclaw.json).

Wiring is dormant — the registry override that consumes these
accessors lands in Step 4. Typecheck + existing acpx/harness/routes
tests pass unchanged.

* refactor(agents): scrub local plan-step references from code comments

Replaces forward-looking comments that referenced internal plan
steps (e.g. "Step 4 wires this into…") with comments that justify
the code on its own merits. Plan files live locally on the
contributor's machine, so cross-references are noise to the rest of
the project.

No behavior change.

* feat(agents): spawn openclaw ACP adapter inside the gateway container

When the harness resolves the `openclaw` adapter, it now returns a
command that runs `openclaw acp` inside the bundled gateway container
via `limactl shell <vm> -- nerdctl exec -i ... openclaw acp --url
ws://127.0.0.1:<port>`. This reuses the openclaw binary already
installed alongside the gateway — no host-side openclaw install is
required.

Auth: the gateway token is injected via OPENCLAW_GATEWAY_TOKEN on
the container exec rather than `--token` on the openclaw CLI, so
the secret never appears in `ps aux`.

Banner output: OPENCLAW_HIDE_BANNER=1 and OPENCLAW_SUPPRESS_NOTES=1
keep stdout JSON-RPC-clean.

LIMA_HOME: prefixed via `env LIMA_HOME=<path>` on the resolved
command so the spawned limactl finds the BrowserOS-owned VM (the
server doesn't set LIMA_HOME on its own process env).

When the gateway accessor is absent, falls through to acpx's
built-in openclaw adapter which assumes a host-side install — that
branch will fail at spawn time with a descriptive error.

Verified end-to-end via the existing acp-smoke script during the
Step 0 spike.

* feat(agents): dual-create OpenClaw harness agents on the gateway

When the harness creates an `openclaw` adapter agent, it now also
provisions a matching agent on the OpenClaw gateway via the existing
CLI path (OpenClawService.createAgent). Symmetric on delete: gateway
removeAgent runs alongside the harness-store delete.

- Adds an OpenClawProvisioner interface (decoupled from OpenClawService
  for testability) and injects it through AgentHarnessService.
- createAgent rolls back the harness record if gateway provisioning
  fails; deleteAgent tolerates gateway-side failures so harness
  identity stays consistent with the user-facing UI.
- New OpenClawProvisionerUnavailableError surfaces as a 503 when an
  openclaw create request lands on a harness with no provisioner
  wired in (instead of a generic 500).
- FileAgentStore mints openclaw agent ids with an 'oc-' prefix so
  the id satisfies the gateway's `^[a-z][a-z0-9-]*$` agent name
  pattern. Other adapters keep raw UUIDs to preserve compatibility.
- POST /agents body schema accepts providerType / providerName /
  baseUrl / apiKey / supportsImages, forwarded to the provisioner
  when adapter='openclaw'.

The agents-page UI still routes openclaw create through the legacy
/claw/agents flow; switching that path to the harness is a separate
UI cutover.

Tests cover: gateway dual-create on success, rollback on gateway
failure, 503 when provisioner is missing, and tolerant delete on
gateway-side failure.

* fix(agents): skip catalog model validation for OpenClaw adapter

OpenClaw agents resolve their model from the gateway-side provider
config (set at agent-create time via OpenClawService) rather than
from the harness catalog, which has an empty `models: []` entry by
design. Without this carve-out, every OpenClaw create body fails
parsing with "Invalid modelId" because no concrete model id can
satisfy isSupportedAgentModel('openclaw', ...).

The reasoning-effort check still runs against the catalog (those
values map directly to OpenClaw's session `thought_level` config
option).

* fix(agents): pass --session to openclaw bridge so newSession routes correctly

acpx's AcpClient.createSession calls connection.newSession with cwd
and mcpServers but never forwards the sessionKey. Without it, the
openclaw bridge falls back to a synthetic acp:<uuid> session that
doesn't resolve to any provisioned gateway agent — every harness
chat returns a generic "Internal error" from -32603.

Fix: bake `--session <key>` into the resolved spawn command. The
bridge then uses that as the default session key for any newSession
the bridge receives, routing the turn to the matching gateway agent.

Per-session keying means each openclaw agent gets its own
AcpxCoreRuntime instance (cached by sessionKey on top of the
existing cwd/permissionMode key). This adds one extra runtime per
active openclaw session — claude/codex are unaffected.

Test asserts the resolved command includes the right --session arg.

* fix(agents): suppress BrowserOS MCP for openclaw bridge

The openclaw ACP bridge rejects newSession when mcpServers is non-empty
because its provider tooling comes from the gateway, not from ACP-side
MCP servers. Forwarding the BrowserOS HTTP MCP made every harness chat
fail with a JSON-RPC -32603 "Internal error" before the session was even
opened. Claude/codex still need the BrowserOS MCP for browser tooling,
so the carve-out is keyed off whether the runtime is for an openclaw
session.

* feat(agents): route OpenClaw chat through the harness behind a flag

Adds the `feature.useAcpxForOpenClaw` extension storage flag. When on,
OpenClaw agents in the agent-command chat panel use the harness
/agents/<id>/chat SSE and harness history hook instead of the legacy
/claw/agents/<id>/chat. When off, behavior is unchanged.

Also dedupes the agent rail when the same id appears in both stores
(dual-created agents from /claw/agents and /agents) by preferring the
harness entry — without this, every dual-created OpenClaw agent shows
up twice after Step 5.

Image attachments are temporarily disabled when the harness path is
active; the carve-out lands in the next commit.

* fix(agents): keep legacy OpenClaw agents on ClawChat

The previous commit's flag-gated branch routed every `source='openclaw'`
agent through `/agents/<id>/chat` when the flag was on, but the layout
dedup means the only agents that ever reach that branch are legacy
gateway-only entries (`main`, orphan agents from rolled-back creates) —
which by definition have no harness record, so the harness path 404s
and chat is unusable. Source is the only routing signal again: harness
agents go through the harness, legacy agents stay on ClawChat. The
storage flag stays for Step 9/10's migration story.

* feat(agents): expose OpenClaw in sidepanel and route through gateway main

`buildSidepanelChatTargets` now emits a single default ACP target for
adapters with no per-session model picker (OpenClaw, whose model is
configured on the gateway-side agent). Without this, OpenClaw never
appeared in the sidepanel target picker because the catalog entry has
`models: []`.

Sidepanel sessions don't have a dedicated provisioned gateway agent.
The openclaw bridge `--session` flag previously got the raw sidepanel
key (`sidepanel:<convId>:openclaw:...`), which doesn't match any
gateway agent — newSession was accepted but every prompt hung
forever. The bridge command now rewrites non-harness session keys
onto the always-present `main` gateway agent, encoding the original
key as a channel suffix to keep state segregated per conversation.
Verified end-to-end via curl: sidepanel openclaw chat streams
`text-delta` + `finish: stop`.

* feat(agents): backfill harness records for legacy gateway agents

Reframes Step 9 of the OpenClaw-on-acpx migration. The plan's literal
Step 9 (route OpenClaw history through the harness when the flag is on)
was already a no-op after the Step 6 walkback — history is routed by
source today. The actual blocker for Steps 10–13 was that legacy
gateway-only agents (e.g. `main`, orphans from rolled-back creates) had
no harness record, so they could never migrate to the harness path
without breaking chat.

`AgentHarnessService.reconcileWithGateway()` now lists every gateway
agent and upserts a matching harness record for any that are missing.
The pass runs lazily on first `listAgents()` call (memoized on success,
retried on failure so a gateway-down boot doesn't permanently disable
backfill). Verified end-to-end: the legacy `agent` agent now streams
`text_delta` + `done(end_turn)` through `/agents/agent/chat`, with the
bridge resolving to the gateway's `agent` record via the existing
`agent:<name>:main` session-key format.

After this, every OpenClaw agent surfaces as `source='agent-harness'`
post-dedup, the legacy `useClawChatHistory` hook becomes unreachable
for OpenClaw, and Steps 11–13 (delete legacy chat/history paths) are
unblocked.

* fix(agents): drop duplicate OpenClaw entry from NewAgentDialog adapter list

The adapter Select hardcoded an `<SelectItem value="openclaw">OpenClaw</SelectItem>`
on top of iterating `adapters`, which now includes OpenClaw post the
catalog change. The dropdown rendered "OpenClaw" twice — once at the
top, once at the bottom of the list. The literal was a pre-catalog
artifact; removing it leaves a single OpenClaw entry sourced from the
catalog. Routing into `handleOpenClawCreate` is unchanged because
the value (`'openclaw'`) is identical either way.

* fix(agents): always reconcile harness with gateway on list, just dedupe concurrent calls

Memoizing the first successful reconcile meant new gateway agents (created
via the legacy /claw/agents path or out-of-band CLI) never appeared in the
harness until server restart. The Promise now serves as a concurrent-call
dedupe only — cleared on settle — so every listAgents call picks up the
current gateway state. Reconcile is one cheap idempotent CLI call.

* chore(agents): remove dormant useAcpxForOpenClaw flag

The flag was scaffolded in Step 6 but its routing effect was walked
back the same day after it broke chat for legacy gateway-only agents.
After the Step 9 backfill, every OpenClaw agent has a harness record
and routes through the harness path purely from `source='agent-harness'`
— no flag is consulted anywhere. Remove the dead storage item, hook,
and stale comment.

* refactor(agents): drop legacy /claw/agents/:id/history endpoint

The harness /agents/:id/sessions/main/history endpoint replaced this
once every OpenClaw agent got a harness record (Step 9 backfill).
Routing is fully source-driven now, so the UI's useClawChatHistory
hook is never enabled today — verified live: legacy URL returns 404,
harness history hydrates correctly for the same agent.

Removes the GET /claw/agents/:id/history route, OpenClawService's
getAgentHistoryPage method plus its cursor/limit helpers and the
history-only types it owned (BrowserOSOpenClawHistoryPageResponse,
HistoryPageInput, normalizeHistoryLimit, encodeHistoryCursor,
decodeHistoryCursor, jsonlEventsToHistoryItems), and the route +
service tests that covered the dropped endpoint.

OpenClawJsonlReader stays alive — still feeds /claw/dashboard,
/claw/agents/:id/sessions, and the boot-time clawSession seed.
Removing those is its own follow-up since the dashboard would need
a harness-side replacement first.

* feat(agents): wire image attachments through the harness ACP path

Composer attachments now flow into the ACP `prompt` request as
spec-compliant `image` content blocks alongside the user's text. End
to end:

  composer → chatWithHarnessAgent({attachments}) →
  POST /agents/:id/chat {message, attachments} →
  parseChatBody decodes data: URLs to {mediaType, base64} →
  AgentHarnessService.send forwards →
  AcpxRuntime.send forwards →
  acpx startTurn({attachments}) → ACP image blocks

UI no longer disables the attach button on harness agents — the
gating was just a placeholder before this commit landed. Verified
end to end with a 1×1 red PNG against a Claude harness agent: model
replies "Red." correctly.

OpenClaw's `acp` bridge still drops image content blocks upstream
(verified by the same probe — Kimi-k2p5 reports "I don't see an
image"). That's an upstream openclaw limitation, not a harness-side
gap; Claude/Codex agents work as advertised today.

* chore(openclaw): delete OpenClawJsonlReader and JSONL-backed routes

* chore(openclaw): remove legacy /claw/agents/:id/chat and /queue routes

* chore(agents): collapse chat panel to harness-only path

* feat(agents): route OpenClaw image turns through the gateway HTTP client

The OpenClaw `acp` bridge silently drops ACP `image` content blocks
(verified during dogfood — model says "I don't see an image"). When
the user attaches images to an OpenClaw agent, the harness now diverts
that turn to the gateway's HTTP `/v1/chat/completions` endpoint, which
accepts OpenAI-style `image_url` parts and forwards them natively to
the provider.

  - New `OpenClawGatewayChatClient` translates an OpenAI streaming
    response into the same `AgentStreamEvent` shape the rest of the
    harness already consumes, so the chat panel renders identically
    whether a turn went through ACP or the gateway carve-out.
  - `AcpxRuntime.send` forks at the top: openclaw + any image
    attachment + a wired gateway client → `sendOpenclawViaGateway`.
    Other turns (text-only openclaw, claude, codex) take the existing
    ACP path unchanged.
  - The diverted path reads the prior turn history from the acpx
    session record so context is preserved, builds the OpenAI
    multimodal user message with text + image_url parts, and pumps
    the gateway SSE back to the caller through a tee that accumulates
    the assistant text. On natural completion, persists a synthetic
    user+assistant message pair to the acpx session record so reload
    shows the image turn in history.
  - Wired `OpenClawGatewayChatClient` into `AgentHarnessService` via
    `server.ts` (gateway port + token accessor, just like the existing
    `openclawGateway`).

Persistence note: the acpx record requires User messages to carry an
`id` and Agent messages to carry `tool_results` — without them the
record fails to round-trip through `parseSessionRecord`. The persist
helper now sets both.

Limitation by design: image recognition only works if the OpenClaw
agent's provider supports vision (e.g. Claude-via-OpenClaw, GPT-4o).
The pipeline routes images correctly to the provider regardless;
text-only providers like Kimi-k2p5 will reply "I don't see an image"
because the model itself has no vision capability — that's a provider
config issue, not a routing bug. The unit test asserts the image_url

* feat(agents): validate inbound image attachments on /agents/:id/chat

The harness chat body parser was accepting any mediaType and any
dataUrl length. The composer enforces these caps client-side but the
endpoint also serves direct curl/script callers, so the server has to
defend itself.

Restores the same caps the legacy /claw/agents/:id/chat parser had
before it was deleted in the migration:

  - 10 attachments per message
  - 5 MB raw image bytes (≈ 6.7 MB once base64-encoded plus prefix)
  - PNG / JPEG / WebP / GIF only
  - Must start with `data:`

Each violation returns 400 with a specific error message instead of
silently dropping or forwarding the payload.
