Summary

The gateway half of relay Phase 3 option B2: inbound (messages + /stop interrupts) now arrives over the gateway's outbound /relay WebSocket, not a signed HTTP POST to an inbound endpoint. The gateway needs no inbound HTTP port — which is what makes hosted gateways (no public IP) able to receive inbound at all.

Pairs with gateway-gateway (relay bus + WsGatewayDelivery) and the NAS GATEWAY_RELAY_URL stamp. The cross-repo E2E (connector repo) proves the full multi-instance path against this production adapter code.

What changed

  • gateway/relay/adapter.pyconnect() wires set_interrupt_inbound_handler(self.on_interrupt) so connector→gateway interrupt_inbound frames bridge into the existing per-session interrupt path (the inbound message handler was already wired). Removed _maybe_start_inbound_receiver() + the _inbound_runner lifecycle — there is no HTTP receiver anymore.
  • gateway/relay/inbound_receiver.pydeleted (the signed-HTTP InboundDeliveryReceiver).
  • gateway/relay/__init__.py — removed relay_inbound_config() (dead with the receiver gone). The delivery key is still set in-process by self-provision for forward-compat but is no longer consumed for inbound.
  • docs/relay-connector-contract.md — §3 rewritten (inbound is the WS back-channel, routed cross-instance via the connector's relay bus); §5 interrupt + §6 auth table updated; the old signed-HTTP-POST + per-tenant-delivery-key-signing path documented as superseded. gatewayEndpoint noted as passthrough-plane only.

The WS transport already parsed inbound / interrupt_inbound frames and dispatched the message handler — this PR is largely removing the parallel HTTP path and wiring the one remaining handler, hence the net deletion.

Test plan

  • stub_connector grows set_interrupt_inbound_handler + push_interrupt; a new test_relay_interrupt case proves connect() wires both inbound handlers and that an interrupt_inbound frame over the WS cancels exactly the right session (siblings untouched).
  • Removed the HTTP-receiver test; updated the crypto-shedding scan and the self-provision delivery-key assertion.
  • 88 relay tests pass. Contract-doc conformance test green.

Diffstat

9 files, −478 / +119 (the deletion is inbound_receiver.py + its test). Additive-safe within the EXPERIMENTAL relay surface.

EXPERIMENTAL: the relay contract may change until ≥2 Class-1 platforms validate it.

inbound rides the outbound socket

The connector now delivers inbound (messages + interrupts) over the gateway's
OUTBOUND /relay WebSocket, not a signed HTTP POST to an inbound endpoint. The
gateway needs no inbound HTTP port — which is what makes hosted gateways (no
public IP) able to receive inbound at all.

- gateway/relay/adapter.py: connect() wires set_interrupt_inbound_handler(
  self.on_interrupt) so connector->gateway interrupt_inbound frames bridge into
  the existing per-session interrupt path (the inbound message handler was
  already wired). Removed _maybe_start_inbound_receiver() + the _inbound_runner
  lifecycle — there is no HTTP receiver anymore.
- gateway/relay/inbound_receiver.py: deleted (the signed-HTTP InboundDelivery
  receiver).
- gateway/relay/__init__.py: removed relay_inbound_config() (dead with the
  receiver gone). The delivery key is still set in-process by self-provision for
  forward-compat but is no longer consumed for inbound.
- docs/relay-connector-contract.md: §3 rewritten — inbound is the WS back-channel
  routed cross-instance via the connector's relay bus; §5 interrupt + §6 auth
  table updated; the old signed-HTTP-POST + per-tenant-delivery-key-signing path
  is documented as superseded. gatewayEndpoint noted as passthrough-plane only.

Tests: stub_connector grows set_interrupt_inbound_handler + push_interrupt;
new test_relay_interrupt case proves connect() wires BOTH inbound handlers and an
interrupt_inbound frame over the WS cancels the right session. Removed the
HTTP-receiver test; updated the crypto-shedding scan + self-provision delivery-key
assertion. 88 relay tests pass.

EXPERIMENTAL. Pairs with gateway-gateway (relay bus + WsGatewayDelivery) and the
NAS GATEWAY_RELAY_URL stamp. The cross-repo E2E (connector repo) proves the full
multi-instance path against this production adapter code.

…the engine (#6)

* fix(dashboard): clean up upload temp file on client disconnect + pin python-multipart (NS-501)

Follow-up to #47663 (streaming multipart upload), fixing two issues that
landed with it.

1. Temp file leaked on client disconnect. The streaming upload endpoint's
   except chain caught only HTTPException / PermissionError / OSError — all
   Exception subclasses. asyncio.CancelledError, raised when a browser aborts
   a large upload mid-stream (the exact NS-501 scenario), is a BaseException,
   so it bypassed every except clause and reached a finally that only closed
   the file handle and never unlinked the temp file. Every aborted large
   upload orphaned a partial `.{name}.*.upload` file (up to ~100 MB) in the
   target directory. Cleanup now lives in finally, keyed on a `renamed`
   success flag, so the temp file is removed on every non-success exit
   including BaseException paths. Added test_stream_upload_cleans_temp_on_cancellation,
   which fails on the pre-fix code (leaks the temp file) and passes with the fix.

2. python-multipart pinned to ==0.0.27 instead of ==0.0.20. The package was
   already resolved at 0.0.27 transitively (via daytona) before #47663; the
   explicit ==0.0.20 pin in the [web] extra and the tool.dashboard lazy-install
   set downgraded it. Bumped both to ==0.0.27 and regenerated with `uv lock`,
   keeping the lockfile coherent. The base dependency stays >=0.0.9,<1.

* fix(openviking): adapt memory provider for current api

(cherry picked from commit cbb87389f33583518975fbf72671de3fd224bb28)

* fix(install): resolve PowerShell host instead of bare `powershell` for uv

The Windows installer's Install-Uv spawned the astral uv installer with a
hardcoded bare `powershell -ExecutionPolicy ByPass -c "irm .../uv | iex"`.
That name resolves only to Windows PowerShell, and only when its System32
directory is on PATH. Run under PowerShell 7+ (`pwsh`) — or any session where
`powershell` isn't on PATH — the spawn dies with "The term 'powershell' is not
recognized", and uv installation aborts (the installer then appears stuck).

Add Get-PowerShellHostExe, which prefers the absolute path of the host we're
already running in (PATH-independent), then falls back to powershell/pwsh via
Get-Command, then to the bare name. Install-Uv now invokes that resolved exe.

* test(install): lock uv installer to a resolved PowerShell host

Source-level guard (install.ps1 only runs on Windows, so there's no Linux CI
runner to execute it): the astral uv install line must be invoked via the call
operator on a resolved host variable, the bare-`powershell` literal that
produced the field-reported "The term 'powershell' is not recognized" must be
gone, and the resolver must be PATH-independent (Get-Process -Id $PID) and
pwsh-aware.

* fix(install): relax native stderr handling in install.ps1 (#48352)

* fix(#37878): scrub operator environment before launching cua-driver MCP

- Use _sanitize_subprocess_env() to filter Hermes-managed credentials
  from the cua-driver subprocess environment (issue #37878)
- Prevents credential exfiltration to the third-party cua-driver binary
- Aligns with existing pattern used by browser-tool and other tools
- Add regression test to verify environment sanitization

The cua-driver is a lower-trust MCP subprocess per SECURITY.md §2.3.
Its inherited environment is now scrubbed by default, removing provider
API keys, gateway tokens, and platform credentials that should not leak
to third-party binaries.

Fixes #37878

* fix(#37878): Address review feedback — fix trailing whitespace and add ANTHROPIC_API_KEY test

Review feedback from egilewski:
1. Remove trailing whitespace from test docstring and mock patches (lines 1430, 1469, 1476, 1482)
2. Expand test coverage: also verify ANTHROPIC_API_KEY is stripped (not just OPENAI_API_KEY)

Changes:
- Remove trailing whitespace from test file
- Add ANTHROPIC_API_KEY to test environment
- Add assertion verifying ANTHROPIC_API_KEY is stripped from cua-driver subprocess env
- Syntax verified: python3 -m py_compile tests/tools/test_computer_use.py ✓

* chore(release): map iamlukethedev to AUTHOR_MAP

* fix(skills): rmtree scope guard + default pre_update_backup to true (#48200)

Defense-in-depth fix for the silent wipe of ~/.hermes/ documented in
#48200. A `hermes update --yes` run silently destroyed a user's
.env, MEMORY.md, kanban.db, custom skills, and scripts. Two changes:

1. `_rmtree_writable` in tools/skills_sync.py now refuses to rmtree
   anything outside SKILLS_DIR (the HERMES_HOME/skills/ root).
   All five call sites pass paths under SKILLS_DIR, so the guard is
   a no-op for current code and a loud, recoverable failure for
   any future regression (bad path join, malicious bundled
   manifest, stale path in scope after an exception).

2. The default `updates.pre_update_backup` flips from false to
   true in hermes_cli/config.py. A few minutes of zip per update
   is negligible compared to silent total data loss. Still
   overridable; --no-backup still works for one-off opt-out.

Five new tests in TestRmtreeWritableScopeGuard (root path,
hermes home, sibling dir, skills root itself, subdir) plus a
flipped `test_default_enabled_creates_backup` in test_backup.py.
178/178 tests pass in the two affected files. Public method
signatures unchanged, no test-stub blast radius.

Closes #48200

* fix(skills): refuse SKILLS_DIR root in rmtree guard, not just outside-tree

The salvaged guard allowed _rmtree_writable(SKILLS_DIR) itself. No call
site ever passes the root — every site passes a skill subdir or its .bak
sibling — so allowing the root only preserves the #48200 footgun (a dest
that collapses to the root wipes every installed skill). Require a strict
strict-child relationship and update the test that documented the
nonexistent 'full reset' capability.

* fix(tui): don't make Enter swallow trailing-space-only slash completions (#48425)

* fix(tui): don't make Enter swallow trailing-space-only slash completions

Submitting a slash command in the TUI took three Enter presses: one to
complete the name (/ex → /exit), a second that only appended the trailing
space the gateway adds to keep the classic-CLI prompt_toolkit dropdown open
(/exit → "/exit "), and a third to actually submit.

The composer's submit handler accepted the highlighted completion whenever
applying it changed the input at all, so the whitespace-only delta ate an
extra keypress. Treat a completion whose only change is trailing whitespace
on an already-complete token as "already complete" and fall through to
submit. Partial-name and argument completions (a real token change) still
accept on Enter as before.

The replace/accept logic is extracted into pure helpers (applyCompletion,
completionToApplyOnSubmit) in domain/slash.ts.

* test(tui): cover Enter/completion trailing-space behavior and isolate poller queue

- completionApply.test.ts asserts completionToApplyOnSubmit accepts real
  token completions (partial command name, argument) but returns null for a
  trailing-space-only delta on an already-complete command, so Enter submits
  instead of needing extra presses.
- test_notification_poller_delivers_completion / _skips_consumed previously
  shared the process-global process_registry.completion_queue. Their events
  carry no session_key, so a leaked/concurrent poller could dequeue and
  dispatch them to a fixture agent without run_conversation, flaking CI
  ("AttributeError: '_FakeAgent' object has no attribute 'run_conversation'").
  Isolate the queue per test (fresh queue.Queue via monkeypatch), matching the
  sibling poller tests that already do this.

* feat(mcp-catalog): add official Unreal Engine 5.8 MCP server

Epic's experimental Unreal MCP plugin embeds an MCP server inside the
Unreal Editor process, served over local HTTP (127.0.0.1:8000/mcp by
default). HTTP transport, no auth, no install block — the user enables
the plugin in-editor and Hermes connects to the URL.

Also drops test_optional_mcps_manifests_ship_in_both_wheel_and_sdist:
it asserted wheel/sdist packaging targets for pip/Homebrew/Nix installs,
which Hermes does not support — installs run from the repo checkout, where
the catalog is discovered by directory iteration with no packaging step.

* feat(dashboard): surface full per-MCP catalog detail; fix pip-install doc (#48520)

The dashboard MCP catalog only showed name/description/transport and a
non-clickable source. Users couldn't see what an entry connects to or runs
before installing — the exact detail the docs trust model tells them to vet.

- /api/mcp/catalog now returns transport target (url, or command+args),
  auth_type, git install source/ref + bootstrap commands, default-enabled
  tool hint, and post-install guidance per entry.
- McpPage renders the endpoint URL (http) or command+args (stdio), the git
  install source/ref, a collapsible bootstrap-commands list, setup notes,
  and the source as a clickable link when it's a URL.
- Docs: drop the 'uv pip install -e .[mcp]' quick-start step (Hermes does
  not support pip installs; MCP ships with the standard install) and note
  the dashboard now surfaces this detail.
- Strengthen the catalog endpoint test to assert the new inspection fields.

* fix(install): fail fast when uv venv genuinely fails under relaxed EAP

PR #48372 relaxes EAP=Stop around the uv venv call so PowerShell 5.1
doesn't mistake uv's 'Using CPython ...' stderr for a terminating
NativeCommandError. But relaxing EAP also means a *genuine* uv venv
failure (exit != 0) no longer aborts on its own — Install-Venv would
continue and print 'Virtual environment ready', and in stage mode
Invoke-Stage would report ok=true, even though no venv was created.

Capture $LASTEXITCODE immediately after the relaxed call and throw on
non-zero (Pop-Location first, matching the function's other exit paths),
so the venv stage fails fast instead of falsely succeeding. This is the
explicit guard originally proposed in #48463 (devorun), composed on top
of #48372's reusable helper + regression test.

Adds a regression test asserting the uv venv exit-code capture + throw.

* feat(memory): batch operations for single-turn memory updates (#48507)

The memory tool was strictly one-op-per-call. With the store running near
its char limit by design, a new add that would overflow gets rejected with
'consolidate now, then retry' -- but the model could not consolidate and add
in one call. It had to remove/replace across several turns, then retry the
add, each turn re-sending the whole conversation context. Expensive thrash.

Add an 'operations' array: a list of add/replace/remove ops applied
atomically against the FINAL char budget. The model frees space and adds new
entries in ONE call, even when an add alone would overflow. All-or-nothing:
any bad op aborts the whole batch, nothing written.

Root-cause note: the two agent-level memory interception sites
(agent_runtime_helpers.py, tool_executor.py) silently dropped any param not
in their explicit kwarg list, so 'operations' never reached the handler and
batch calls failed with 'Unknown action None'. Both now pass it through and
bridge each add/replace op to external memory providers.

Also: success response is now terminal (done=true + 'do not repeat' note,
no full-entries echo that invited re-edits); schema rewritten to lead with
the batch mechanism and an explicit one-shot stop rule (2138 -> 1476 chars).

Live-verified: near-full consolidate-and-add went 7 calls -> 1 call,
stable across 3 reps. 103 memory/approval tests + 398 background-review/
run_agent tests green; 6 new batch tests added.

* fix(desktop): never persist or restore a named custom provider as bare "custom" (#48547)

* Port from cline/cline#11514: encourage parallel tool calls

Add a universal system-prompt guidance block telling the model to batch
independent tool calls (reads, searches, web fetches, read-only commands)
into a single assistant turn instead of one call per turn. The runtime
already executes independent batches concurrently (read-only tools always;
non-overlapping path-scoped file ops); the open-source system prompt had
nothing steering the model to PRODUCE the batch. Fewer round-trips means
less resent context, which compounds over a long conversation.

- prompt_builder.py: new PARALLEL_TOOL_CALL_GUIDANCE block (short, static,
  cache-amortised) modeled on TASK_COMPLETION_GUIDANCE.
- system_prompt.py: inject right after the task-completion block, gated by
  agent.valid_tool_names + the new toggle.
- agent_init.py: read agent.parallel_tool_call_guidance (default True).
- config.py: add the default under the agent section.
- test_prompt_builder.py: behavior-contract tests (batching steer, dependent
  carve-out, length bound) — invariants, not wording snapshots.

Adapted from Cline's TypeScript tool-surface guidance to hermes-agent's
Python prompt-assembly architecture and config-over-env conventions.

* fix(desktop): never persist or restore a named custom provider as bare "custom"

Custom providers vanish from the Desktop/TUI model picker with
"No LLM provider configured" — repeatedly fixed (#44062, #44109, #45578)
and repeatedly regressed (#44022, #47714) because every fix only recovered
the entry identity from a persisted base_url. When a session is
persisted/restored with the resolved provider "custom" and NO base_url, bare
"custom" leaked through verbatim; resolve_runtime_provider("custom") routes to
the OpenRouter default URL with no api_key, so the next turn/resume dies.

Bare "custom" is the resolved billing class shared by every named providers:/
custom_providers: entry — it is not a routable identity. Centralize the
"never let bare custom escape" invariant in one helper,
runtime_provider.canonical_custom_identity(), and apply it at all four leak
sites in tui_gateway/server.py:

- _ensure_session_db_row  — the ORIGIN: first DB write seeds the bad row
- _runtime_model_config   — live persist
- _stored_session_runtime_overrides — resume restore (heals old rows; drops
  unrecoverable bare custom so resume falls back to config default)
- _make_agent             — rebuild / per-turn

The helper recovers custom:<name> from the endpoint URL when present, else
from config.model.provider (the durable identity left when no base_url
survived). Regression tests in test_custom_provider_session_persistence.py
lock the no-base_url vector at every site so it cannot regress again.

* fix(prompt): dedupe parallel-tool-call steer; correct its rationale

The universal PARALLEL_TOOL_CALL_GUIDANCE block already lives on main, but it
shipped with two rough edges this change cleans up:

- It duplicated the batching steer for Google models. The
  GOOGLE_MODEL_OPERATIONAL_GUIDANCE block still carried its own
  "Parallel tool calls" bullet, so Gemini/Gemma received the instruction
  twice in one prompt. Drop the redundant bullet — the universal block is now
  the single source.
- Its comment claimed "nothing in the open-source system prompt encouraged
  batching," which was wrong: the steer existed for Google models only. Reword
  to say the gap was that every *other* model got nothing.
- Tighten the test that asserts the steer (precedence-correct), and add an
  invariant guarding against re-introducing the Google duplicate.

* fix(desktop,tui): surface self-improvement review summary + honor memory_notifications

The "💾 Self-improvement review" summary (skill/memory updated) was invisible
on two surfaces:

- Desktop Electron app had no review.summary event handler — skill/memory
  writes happened silently. Now appends a persistent system message to the
  transcript (matching the Ink TUI's persistent-line semantics, not a
  transient toast that can be missed).
- tui_gateway (backs both 'hermes --tui' and the desktop) never read
  display.memory_notifications, so it always behaved as 'on' and ignored a
  user who set 'off'/'verbose'. Added _load_memory_notifications() (mirrors
  the messaging gateway's bool->str normalization, defaults to 'on') and
  wired it to agent.memory_notifications, matching gateway/run.py and the CLI.

Delivery chain now reaches all surfaces:
background_review.py -> background_review_callback -> review.summary event ->
desktop transcript / Ink TUI line / gateway message / CLI print.

* fix(dashboard): use DS Button prefix/size API instead of inline icons

@nous-research/ui@0.18.2 Button is grid-based: size=xs is an
aspect-square icon-only box, and icons belong in prefix/suffix.
The dashboard used shadcn-style size=xs + inline <Icon/> text
children, which forced text buttons into broken tall squares
(Configure, Run setup, Select, Save keys) and split icon/label
across grid columns elsewhere (Schedule it, Prune/Delete actions).

Move leading icons to prefix and size text buttons as sm/default.
For the post-setup spinner, drive the spin from a button-level
[&_svg]:animate-spin selector since the prefix slot clones the
icon and overwrites its className.

- ToolsetConfigDrawer: Select, Save keys, Run setup
- SkillsPage: New skill, Configure
- AutomationBlueprints: Schedule it
- SessionsPage: Prune old sessions, Delete empty, Delete selected

* feat(billing): /billing terminal billing — interactive TUI + CLI client (#45449)

* feat(billing): nous_billing http client + BillingState core (phase 2b)

Phase 2b terminal-billing client foundation:
- hermes_cli/nous_billing.py: typed client for the 4 /api/billing/* endpoints
  (state/charge/poll/auto-top-up). Raises typed errors (BillingScopeRequired,
  BillingRateLimited, BillingAuthError) mapped from the live-verified contract;
  fail-open is the caller's job. Idempotency-Key enforced client-side.
- agent/billing_view.py: surface-agnostic BillingState core + Decimal money
  parsing (server emits decimal strings, not 2dp), fail-open builder,
  idempotency-key gen, custom-amount validation.
- 51 unit tests (decimal parse/format, payload tiering, error->exception
  matrix, fail-open, amount validation).

Plan: docs/plans/2026-06-13-001-phase-2b-terminal-billing-tui-plan.md

* feat(billing): billing:manage scope + lazy step-up re-auth (phase 2b)

- NOUS_BILLING_MANAGE_SCOPE constant.
- nous_token_has_billing_scope(): split-based scope check (no false-positive
  substring match).
- step_up_nous_billing_scope(): re-runs the device flow requesting
  billing:manage, reusing the held credential's portal/inference URLs + client_id
  (so a preview stays a preview), persists like _login_nous but WITHOUT the model
  picker. Returns True iff the minted token carries the scope (False when NAS
  silently downscopes a non-admin / unticked grant).

Lazy step-up (plan D-A): normal login path unchanged; 403 insufficient_scope
from a billing call triggers this. 7 unit tests.

* feat(billing): billing JSON-RPC methods for the TUI (phase 2b)

billing.state / charge / charge_status / auto_reload / step_up in
tui_gateway/server.py. Return STRUCTURED success envelopes (result.ok +
result.error=<code>) rather than JSON-RPC-level errors, so the Ink rpc() promise
always resolves and the TUI branches on the typed billing error code
(insufficient_scope, rate_limited, no_payment_method, …) to render the right
affordance. Money serialized as decimal STRINGS + display strings. charge mints
+ echoes an idempotency_key for retry reuse. 16 unit tests.

* feat(billing): /billing CLI handler + command registry (phase 2b)

- CommandDef("billing", subcommands=buy|auto-reload|limit), added to
  _SLACK_VIA_HERMES_ONLY so it routes via /hermes on Slack (keeps the 50-cap
  parity test green, same as /credits).
- cli.py::_show_billing + screen helpers: all 5 screens (overview, buy→confirm→
  poll, auto-reload, monthly-limit read-only). Reuses _prompt_text_input_modal /
  _prompt_text_input (D-C). Non-interactive (_app is None) renders text + portal
  deep-link, never prompts (R7). Decimal money end-to-end. 2s/5-min cancellable
  poll loop; 429/503 = retry not failure; settled = ledger truth. Lazy step-up on
  403 insufficient_scope. no_payment_method treated as mainline funnel-to-portal.
- 6 CLI tests; 156 command tests (incl. Slack/Telegram parity) green.

* feat(billing): /billing Ink TUI screens + tests (phase 2b)

- ui-tui/src/app/slash/commands/billing.ts: /billing TUI command covering all 5
  screens — overview (text), buy <amt> → ConfirmReq → charge → non-blocking 2s/
  5-min poll loop → settled/failed/timeout branches, auto-reload <below> <to> →
  ConfirmReq → PATCH, limit (read-only). Reuses the existing ConfirmReq overlay
  (D-C) — no bespoke component. Typed-error envelope branching: insufficient_scope
  arms the lazy step-up confirm; no_payment_method/rate_limited/cap funnel to
  portal. Client-side amount validation mirrors the server (bounds + 2dp).
- gatewayTypes.ts: Billing* response interfaces.
- registry.ts: register billingCommands.
- billingCommand.test.ts: 12 vitest cases (overview/gating/buy-confirm-poll-
  settled/no_payment_method/step-up/limit/auto-reload/validation).

TUI build green; 12/12 vitest pass; slash tests pass once @hermes/ink is built.

* docs(billing): scrub private cross-repo references

NAS is a private repo — remove all references to it from the public PR:
- drop the cross-repo planning doc (planning scaffolding, not a deliverable;
  the PR description documents the design)
- replace 'NAS' / 'PR #412 preview' mentions in code + test comments with
  generic 'the server' / 'a preview deployment'

* docs(billing): scrub final NAS reference in step-up docstring

* docs(billing): drop dangling plan-doc refs

The phase-2b plan doc was removed in the cross-repo scrub (300afcc0b)
but two module docstrings still pointed at it. Drop the dead refs.

* feat(billing): interactive /billing overlay + step-up UX, portal-URL & token fixes

Adds the interactive /billing TUI overlay and hardens the terminal-billing
client across CLI and TUI.

- TUI: full /billing overlay state machine (overview to buy to confirm,
  auto-reload, read-only monthly limit) reusing the existing confirm overlay.
- Step-up: surface the verification link in-transcript and open the browser
  via the TUI's own opener (the device flow runs in the headless gateway, so a
  printed URL was being dropped); run the step-up handler off the main loop and
  emit the link as an out-of-band event so the gateway stays responsive.
- Step-up copy is scope-accurate ("Billing permission granted") and re-checks
  /state so it never claims "enabled" when the org kill-switch is still off.
- Portal deep-links resolve to absolute URLs against the active portal base
  (the server emits them relative) - fixes a bare "/billing?topup=open" link.
- Billing calls refresh an expired access token via the stored refresh token
  instead of reporting a false "not logged in".
- Optimistic funnel: advise "set up a saved card on the portal" up front when
  no card is on file (advisory, not a hard gate).
- Token resolution is cached briefly so the 2s charge poll loop stops
  re-locking + re-reading the auth store on every tick; 401 re-resolves fresh.
- Remove the temporary demo-mode shims.

Validation: 87 Python billing tests, 88 TS tests (billing command + gateway
event handler), tsc clean, ink + ui-tui builds green.

* docs(billing): add /billing TUI screenshots for PR

* fix(cli): guard _last_invalidate on bare instances; update stale prompt-fallback test

The UI-invalidate throttle read self._last_invalidate unconditionally, which
raised AttributeError on HermesCLI instances built without __init__ (the
thread-safety test's object.__new__ shell). Guard the read with getattr.

The off-main-thread branch of _prompt_text_input was changed (#23185) to cancel
cleanly to None instead of falling back to a bare input() that would hang on the
slash-worker thread; the test still asserted the old direct-input fallback.
Update it to assert the current intended behavior: returns None, calls neither
run_in_terminal nor input(), and does not hang.

* fix(agent): flush un-persisted messages before session rotation (#47202)

compress_context() rotates the session (end_session -> create_session)
mid-turn when auto-compress triggers, but never called
_flush_messages_to_session_db() first. Messages generated during the
current turn that hadn't been persisted to state.db were silently lost.

The same bug existed in cli.py:new_session() (/new command). Both paths
now flush un-persisted messages before ending the old session.

* fix(gateway): preserve original transcript when /compress rotation is skipped

The manual /compress handler called rewrite_transcript() unconditionally on
the session id returned by _compress_context(). When rotation does not occur
(e.g. _session_db unavailable, or the DB split raised), session_id is unchanged
and rewrite_transcript() DELETEs the original messages and replaces them with
only the compressed summary — permanent data loss (#44794, #39704).

Guard the rewrite on actual rotation: only overwrite when _compress_context
produced a new session id. Otherwise leave the original transcript intact and
log a warning.

* fix(thread): allow scrolling long user messages in chat history (#48619)

* fix(picker): remove max_models=50 cap in interactive model pickers

The interactive model pickers (Desktop REST API, TUI model.options, CLI
/model) were hard-capped at max_models=50, which truncated large provider
catalogs like Kilo Gateway (336 models) to just 50 entries. This made
most models undiscoverable via the picker search box.

Changes:
- Change build_models_payload() default from max_models=50 to None (unlimited)
- Change list_authenticated_providers() default from max_models=8 to None
- Change list_picker_providers() default from max_models=8 to None
- Fix all [:max_models] slicing to handle None as 'no limit'
- Remove max_models=50 from 5 interactive picker callers:
  * web_server.py: get_model_options (Desktop /api/model/options)
  * web_server.py: get_recommended_default_model
  * model_switch.py: prewarm_picker_cache_async
  * tui_gateway/server.py: model.options JSON-RPC
  * cli.py: HermesCLI model picker
- Telegram/Discord inline keyboard picker (gateway/slash_commands.py)
  still passes max_models=50 explicitly — unchanged behavior.

The total_models field was already in the response payload and is now
meaningful since models.length == total_models for interactive pickers.

Fixes #48279

* fix(picker): keep max_models=0 distinct from unlimited; lock cap semantics

Follow-up to the cap-removal salvage. The contributor guarded the new
unlimited default with `[:max_models] if max_models else ...`, which conflates
max_models=0 (used by slug-only callers that want an empty model list) with
None (unlimited). Tighten to `is not None` at all five slicing sites in
list_authenticated_providers / list_picker_providers, and add a regression test
asserting the three-way contract: None=full, 0=empty, N=first N.

* fix(gateway): resume follows the compression tip so post-compression replies render

Auto-compression ends the live session and forks a continuation child
(linked via parent_session_id). A long-lived parent keeps its own flushed
message rows, so resolve_resume_session_id()'s empty-head walk never
redirected it — resuming the parent id reloaded the pre-compression
transcript and dropped every turn generated after compression, including
the assistant's response. On the desktop this is the recurring "I sent a
message, came back, and the reply isn't there" report on large sessions:
the chat's routed id is the pre-rotation id, and both the gateway
session.resume RPC and the REST /messages read anchored on it.

Fix the resolver at the chokepoint: resolve_resume_session_id() now
follows the compression-continuation chain forward via get_compression_tip()
before its existing empty-head descendant walk. get_compression_tip() only
follows children whose parent ended with end_reason='compression' (created
after the parent was ended), so delegation/branch children never hijack a
resume. This fixes every resume caller at once (REST /messages, CLI
--resume, gateway /resume).

session.resume in tui_gateway was the one resume path that never called the
resolver — it used the raw target id directly. Route it through
resolve_resume_session_id() too (non-lazy only; lazy watch windows must
stay on their exact child branch). Resolving up front also re-anchors the
live-session fast path so a still-live rotated session is reused by its new
key instead of rebuilding a duplicate agent on the stale parent.

Tests:
- resolve_resume_session_id follows the tip even when the parent retains
  messages, and is not confused by a delegation child.
- session.resume binds the agent to the continuation tip and returns the
  post-compression reply.

* test: narrow db._conn before raw SQL so ty stops flagging None-union access

The new compression-tip tests poke started_at/ended_at directly via
db._conn to force deterministic lineage ordering. _conn is typed
Optional[Connection], so ty flagged .execute/.commit as unresolved on
None. Bind a local and assert it's non-None first to narrow the union.

* feat(kanban): auto-subscribe calling session on kanban_create

When a worker calls kanban_create from inside a session that has a
persistent delivery channel, the originating session is now subscribed
to the new task's completion/block events automatically. The agent
that dispatched the task gets notified instead of having to poll.

- Gateway sessions (telegram/discord/slack): HERMES_SESSION_PLATFORM +
  HERMES_SESSION_CHAT_ID ContextVars, set by the messaging gateway.
- TUI / desktop sessions: HERMES_SESSION_KEY in the subprocess env.
  The TUI notification poller keys on platform='tui' + chat_id=<key>.
- CLI / cron / test: no persistent channel, no subscription.

Gated by kanban.auto_subscribe_on_create in config.yaml (default True).
Disable to mirror pre-feature behaviour — users who want explicit
kanban_notify-subscribe calls per task can set it to false. This
config gate addresses the design concern that got PR #19718 reverted
upstream (unconditional implicit auto-subscribe on tool-driven
kanban_create was too aggressive for orchestrator users).

HERMES_SESSION_ID is intentionally not a fallback channel — it is
set by ACP/agent subprocess telemetry for every invocation, not just
TUI, so treating it as a notification target would auto-subscribe
every CLI session and re-introduce the over-eager behaviour.

The kanban_create response now includes a 'subscribed' bool so
orchestrators can react if subscription failed (e.g. by falling
back to explicit kanban_notify-subscribe or to polling).

Includes 6 tests covering the gateway / TUI / CLI / partial-context /
gated / add_notify_sub-failure paths. All 90 tests in
test_kanban_tools.py pass; 509 broader kanban tests pass.

* fix(desktop): make session delete idempotent and id-resolving (#48641)

DELETE /api/sessions/{id} was the only session endpoint that didn't
resolve the id (detail, messages, rename, export all call
resolve_session_id) and 404'd when the row was already gone. The desktop
optimistically removes the sidebar row, then RESTORES it and shows the
error on any failure — so deleting a session that had just been reaped
(empty-session hygiene) or removed by a concurrent client resurrected a
ghost row and surfaced "session not found". /goal + auto-compression churn
leaves transient empty rows that race the sidebar snapshot, which is the
exact "I deleted the empty one and got 'session not found'" report.

Resolve exact ids / unique prefixes, and treat an already-absent session
as an idempotent success — DELETE's contract is "ensure it's gone". This
mirrors the bulk-delete endpoint, which already treats ghost ids as
success.

Tests: deleting an absent id is idempotent (200, not 404); delete resolves
a unique prefix; a real session still deletes.

* feat(prompt): configurable per-platform system-prompt hint overrides

Add platform_hints config so an admin can append to or replace Hermes'
built-in platform hint for a single messaging platform (WhatsApp, Slack,
Telegram, ...) without affecting other platforms. Enables enterprise
managed profiles to steer platform-aware skills (e.g. invoke a custom
table-formatting skill on WhatsApp where Markdown tables don't render)
while leaving Telegram/Slack/CLI behavior unchanged.

- hermes_cli/config.py: document platform_hints in DEFAULT_CONFIG
- agent/agent_init.py: load platform_hints -> agent._platform_hint_overrides
- agent/system_prompt.py: _resolve_platform_hint() applies append/replace
  (replace wins; bare string = append shorthand); defensive on bad config
- tests: 16 cases covering append/replace/shorthand/isolation/malformed

Override only affects the platform-hint segment of the system prompt;
SOUL/context/memory tiers and general instructions are unchanged.

* docs(prompt): document platform_hints config override

Adds a 'Customizing platform hints' section to the Prompt Assembly
developer guide covering the append/replace/shorthand shapes, the
defensive fallback, and the cache-stable lifecycle (stable tier,
resolved at build time).

* fix(desktop): show Hindsight memory provider (#37546)

* fix(desktop): show Hindsight memory provider

* feat(desktop): configure Hindsight memory provider

* fix(desktop): limit Hindsight modes to supported setup

* refactor(desktop): generic memory-provider config surface

Replace the bespoke Hindsight settings surface with a declarative,
schema-driven path so adding a memory provider is pure declaration —
no per-provider page, conditional, or endpoint.

- memory_providers.py: declarative registry. Each provider lists its
  fields {key, label, kind, default, options, secret-vs-plain}. Hindsight's
  mode is a select(cloud, local_external), so rejecting local_embedded
  falls out of generic enum validation instead of a hand-written check.
- One generic endpoint pair GET/PUT /api/memory/providers/{name}/config.
  GET returns declared fields + current values (secrets only as is_set,
  never read back); PUT validates selects against their options, writes
  plain fields to the provider config file, secrets to the env store,
  and flips memory.provider.
- ProviderConfigPanel renders straight from the schema, replacing
  hindsight-settings.tsx and the memory.provider === 'hindsight'
  conditional in config-settings.tsx — same pattern as
  toolset-config-panel.tsx off env_vars.

Scoped to memory providers; storage layout is unchanged so the runtime
Hindsight plugin reads the same config.json / HINDSIGHT_API_KEY / provider
keys as before. Tests cover the registry, endpoint behavior (defaults,
write+secret, select rejection, unknown provider, secret-never-returned),
and the generic panel.

* feat(relay): WS-only inbound on the gateway adapter (Phase 3) (#48294)

The connector now delivers inbound (messages + interrupts) over the gateway's
OUTBOUND /relay WebSocket, not a signed HTTP POST to an inbound endpoint. The
gateway needs no inbound HTTP port — which is what makes hosted gateways (no
public IP) able to receive inbound at all.

- gateway/relay/adapter.py: connect() wires set_interrupt_inbound_handler(
  self.on_interrupt) so connector->gateway interrupt_inbound frames bridge into
  the existing per-session interrupt path (the inbound message handler was
  already wired). Removed _maybe_start_inbound_receiver() + the _inbound_runner
  lifecycle — there is no HTTP receiver anymore.
- gateway/relay/inbound_receiver.py: deleted (the signed-HTTP InboundDelivery
  receiver).
- gateway/relay/__init__.py: removed relay_inbound_config() (dead with the
  receiver gone). The delivery key is still set in-process by self-provision for
  forward-compat but is no longer consumed for inbound.
- docs/relay-connector-contract.md: §3 rewritten — inbound is the WS back-channel
  routed cross-instance via the connector's relay bus; §5 interrupt + §6 auth
  table updated; the old signed-HTTP-POST + per-tenant-delivery-key-signing path
  is documented as superseded. gatewayEndpoint noted as passthrough-plane only.

Tests: stub_connector grows set_interrupt_inbound_handler + push_interrupt;
new test_relay_interrupt case proves connect() wires BOTH inbound handlers and an
interrupt_inbound frame over the WS cancels the right session. Removed the
HTTP-receiver test; updated the crypto-shedding scan + self-provision delivery-key
assertion. 88 relay tests pass.

EXPERIMENTAL. Pairs with gateway-gateway (relay bus + WsGatewayDelivery) and the
NAS GATEWAY_RELAY_URL stamp. The cross-repo E2E (connector repo) proves the full
multi-instance path against this production adapter code.

* fix(docker): support WebUI installs from read-only sources (#48541)

* fix(relay): trigger self-provision on relay-config + NAS token, not is_managed() (#48724)

self_provision_if_managed() gated on is_managed(), but is_managed() means
"NixOS/package-manager-managed" (it keys on HERMES_MANAGED or a ~/.hermes/.managed
marker) — NOT "NAS-hosted". A NAS-provisioned Fly agent sets NEITHER, so the gate
was always False and relay self-provision SILENTLY no-oped on exactly the hosted
agents it was built for. Caught live: a staging agent with GATEWAY_RELAY_URL
correctly stamped logged "No messaging platforms enabled" and never dialed the
connector; HERMES_MANAGED was unset on the machine. The unit tests had mocked
is_managed()->True, so they passed while the real trigger never fired (mocked-
trigger blind spot).

Fix: drop the is_managed() gate and rename self_provision_if_managed ->
self_provision_relay. The real trigger is now "relay_url() set + no pinned secret
+ a resolvable NAS token", which is both NAS-independent and self-guarding:
  - NAS-hosted agent: GATEWAY_RELAY_URL + no pinned secret + bootstrapped NAS
    token -> self-provisions.
  - Self-hosted + `hermes gateway enroll`: pinned GATEWAY_RELAY_SECRET -> skipped
    (existing secret-present guard).
  - Self-hosted, unenrolled, no NAS identity: resolve_nous_access_token() fails
    -> graceful no-op (existing fail-soft path).

Security: unchanged trust model. The connector still derives tenant from the
validated NAS token; this only broadens WHEN the provision attempt fires, and
every broadened case is still guarded by token-resolution + pinned-secret-skip.

Tests: replaced the (wrong) "skips when not managed" test with a regression test
proving a NAS host where is_managed()==False STILL provisions; renamed all call
sites; added a "no NAS token -> non-fatal skip" test for the self-hosted branch.
88 relay tests pass.

Relay-adapter lane. EXPERIMENTAL.

* fix(agent): handle missing trigram tokenizer without disabling FTS5

_is_fts5_unavailable_error only matched 'no such module: fts5', but
SQLite builds that ship FTS5 without the optional trigram tokenizer
raise 'no such tokenizer: trigram' instead. This caused SessionDB init
to crash on those builds.

Additionally, the trigram failure path called _warn_fts5_unavailable
which set _fts_enabled = False, globally disabling full-text search
even though the base FTS5 table was created successfully.

Fix:
- Extend _is_fts5_unavailable_error to also match 'no such tokenizer'
- Add _is_tokenizer_unavailable_error to distinguish tokenizer-specific
  failures from whole-module absence
- Only call _warn_fts5_unavailable for module-level failures; skip it
  for tokenizer-specific failures so base FTS5 remains usable

Fixes #47002

* fix(agent): address review feedback on trigram tokenizer fallback

- Scope 'no such tokenizer' matcher to trigram specifically (#779)
- Decouple base FTS and trigram backfill in v11 migration (#1195)
- CJK search falls back to LIKE when trigram unavailable (#3384/#3430)
- Add _trigram_available tracking across init, migration, and startup
- Add regression tests for migration backfill and CJK LIKE fallback
- Add _is_trigram_unavailable_error and _warn_trigram_unavailable helpers

* fix(agent): rebuild base fts without trigram

* fix(cli): surface a visible warning when the session store is unavailable

When SessionDB init fails, the CLI/Desktop previously continued live with only
a buried log line. The chat looks healthy, but the transcript is never written
to state.db — so resume later shows a truncated or empty session and the user
only discovers the loss after the fact (#41386).

Emit a prominent stderr banner at startup when the store is unavailable, making
it explicit that the conversation will not be saved and cannot be resumed, with
a pointer to fix the store. Also set _session_db_unavailable so downstream code
can detect the degraded state.

* chore(release): map chanyoung.kim@nota.ai -> channkim for #47049 salvage

* feat(cli): lock hermes worktrees so concurrent processes can't clobber them

git worktree lock at creation and unlock before removal. A locked
worktree refuses 'git worktree remove' (and prune), so a second hermes
process or a stray cleanup can't silently delete an in-use isolated
worktree. Fail-soft on both paths — a lock/unlock error never blocks
the session or cleanup.

Salvaged from #47029 (Issue #46303). Unlock moved to the actual-removal
path so a preserved (unpushed-commits) worktree stays locked while in use.

* chore: add JoaoMarcos44 to AUTHOR_MAP

* fix(dashboard): resolve chat TUI argv off event loop (#48561)

* fix(dashboard): resolve chat TUI argv off event loop

Dashboard chat now resolves its TUI launch command off the
FastAPI/WebSocket event loop. The resolver can run `npm install` /
`npm run build` through `_make_tui_argv()`, and doing that synchronously
in `/api/pty` can block proxy keepalives and other dashboard WebSocket
work long enough for reverse-proxy deployments to drop the chat
connection.

This keeps the current TUI build policy intact: normal production
launches still run the correctness-first `npm run build` path, while
`HERMES_TUI_DIR` remains the prebuilt/no-build path for distros and
containers. The change only moves the potentially slow resolver work to
a worker thread for the dashboard chat path, serialized by an
`asyncio.Lock` so concurrent chat tabs preserve one-build-at-a-time
behavior. `SystemExit` (node/npm missing) and the profile `HTTPException`
path still propagate cleanly through `asyncio.to_thread()`.

Salvaged from #26124 — rebased onto current main. The async wrapper now
threads the `profile` parameter that `_resolve_chat_argv` gained on main
since the PR was opened, so cross-profile chat is preserved.

* chore: add 0xdany to AUTHOR_MAP

* fix(dashboard): bind chat-argv lock to app.state; cover error propagation

Self-review hardening on top of the salvaged fix:

- Move `_chat_argv_lock` from a module-level `asyncio.Lock()` onto
  `app.state` (initialised in `_lifespan`, lazy fallback via
  `_get_chat_argv_lock`), mirroring `event_lock`. A module-level
  `asyncio.Lock()` binds to whatever event loop is active at import time,
  which is the exact pattern `_get_event_state`'s docstring warns against
  (breaks across TestClient instances / uvicorn reloads). This keeps the
  lock on the running loop.
- Add two tests exercising the real `_resolve_chat_argv_async` →
  `asyncio.to_thread` → lock → re-raise chain: `SystemExit` (node/npm
  missing) and `HTTPException` (invalid profile) both propagate out of the
  worker thread and are caught by `pty_ws`'s existing handlers. The prior
  tests mocked `asyncio.to_thread` away and never covered this path.

* test(dashboard): dedupe pty error-propagation tests; assert close code

simplify-code cleanup pass on the salvage stack:

- Extract the shared scaffolding of the two pty_ws error-propagation tests
  into `_assert_pty_propagates`, keeping the two tests as distinct contracts
  for the `except SystemExit` and `except HTTPException` arms.
- Assert the stable WebSocket close code (1011) instead of relying solely on
  the user-facing "Chat unavailable" notice wording — a behavior contract per
  the AGENTS.md "behavior contracts over snapshots" rule, robust to notice
  rewording. The detail substring ("unknown profile") is still checked for the
  HTTPException case since proving the detail survives the thread hop is the
  point of that test.

No production-code change; the helper exercises the same real
_resolve_chat_argv_async -> asyncio.to_thread -> lock -> re-raise chain.

* feat(model-picker): add Refresh Models control to bust stale model cache (#48691)

The desktop model picker had no way to force a fresh model fetch: model.options
went through the 1h-cached provider_models_cache.json, and there was no flag to
bust it. When a provider's cached list expired and its next live fetch failed,
the picker fell back to the curated static list — silently dropping live-only
models (e.g. OpenCode Zen's free tier like deepseek-v4-flash-free) the user had
been using.

- Thread refresh through model.options (RPC + REST /api/model/options) ->
  build_models_payload -> list_authenticated_providers, which calls
  clear_provider_models_cache() up front when set so every row re-fetches live.
- Add a 'Refresh Models' control to the desktop picker (5-locale i18n, spinning
  sync icon). Normal opens leave refresh=false to stay snappy on the cache.

Verified: stale cache hides deepseek-v4-flash-free -> refresh busts it -> live
re-fetch surfaces it. refresh=false never touches the cache.

* feat(image-gen): add image-to-image / editing to image_generate (#48705)

* feat(image-gen): add image-to-image / editing to image_generate

Brings image generation to parity with video generation: the unified
image_generate tool now edits/transforms a source image (image-to-image)
when given image_url / reference_image_urls, routing to each backend's
edit endpoint, exactly as video_generate routes to image-to-video.

- ImageGenProvider ABC: generate() gains keyword-only image_url +
  reference_image_urls; new capabilities() declares modalities +
  max_reference_images (defaults to text-only, backward compatible).
  success_response gains a modality field; adds normalize_reference_images.
- image_generate tool: schema exposes image_url + reference_image_urls;
  dynamic schema reflects the active model's actual edit capability so the
  agent knows when image_url is honored. Handler + plugin dispatch forward
  the new inputs; legacy/text-only providers get a clear modality_unsupported
  error instead of silently dropping the source image.
- In-tree FAL: 7 models gain edit endpoints (flux-2-klein, flux-2-pro,
  nano-banana-pro, gpt-image-1.5, gpt-image-2, ideogram/v3, qwen-image)
  with per-model edit_supports whitelists + reference caps; routes to the
  /edit endpoint and skips the upscaler for edits.
- Plugins: openai (images.edit, 16 refs), xai (/v1/images/edits via
  grok-imagine-image-quality, JSON body per xAI docs), krea
  (image_style_references, 10 refs). openai-codex stays text-only and
  rejects edits with an actionable error.
- Tests: 15 new (payload, routing, dispatch forwarding, dynamic schema,
  capabilities); updated 2 change-detector/lambda tests for the new schema.
- Docs: image-generation feature page, image-gen provider plugin guide,
  tools reference.

* fix(image-gen): preserve legacy passthrough in fal/krea plugin tests

Two existing plugin tests asserted pre-image-to-image behavior:
- fal: forward image_url/reference_image_urls only when supplied, so a
  text-to-image delegation stays byte-identical (no None kwargs).
- krea: keep dict-shaped image_style_references refs verbatim (the unified
  string refs go through normalize_reference_images; legacy non-string ref
  objects pass through unchanged) — fixes KeyError when callers pass the
  richer Krea ref-object shape.

* fix(image-gen): clearer not-capable message for text-to-image-only models

When a text-to-image-only model (incl. gpt-image-2 on the Codex OAuth path,
which can't do editing through the Responses image_generation tool) gets a
source image, say 'this model is not capable of image-to-image / editing —
provide a text-only prompt' rather than sending the user shopping for other
backends. Applies to the openai-codex guard, the in-tree FAL no-edit-endpoint
error, and the dynamic tool-schema text-only line.

* fix(terminal): block gateway lifecycle commands from inside the gateway process

systemctl --user restart hermes-gateway run via the terminal tool is a
child of the gateway itself. When systemd delivers SIGTERM the gateway
kills this subprocess before it can complete, so the service may never
restart — reproducing issue #37453.

The hermes gateway restart/stop guard (hermes_cli/gateway.py) and the
cron-path guard (hermes_cli/cron.py) already block equivalent commands
in their respective paths but the terminal tool had no such defense.

Add a hard-block before command execution in terminal_tool: when
_HERMES_GATEWAY=1 and the command matches _contains_gateway_lifecycle_command,
return an error immediately. force=True cannot bypass it — unlike the
normal dangerous-command approval flow, here even a user-approved restart
would fail because the SIGTERM propagates to child processes.

Also extend _GATEWAY_LIFECYCLE_PATTERNS to match systemctl with flags
(e.g. systemctl --user restart) — the previous regex required the
action word immediately after systemctl with no flags in between.

Adds 9 regression tests: 6 blocked variants (parametrized), force bypass
attempt, safe systemctl passthrough, and guard-inactive-outside-gateway.

* fix(relay): make hosted gateways actually connect AND complete the inbound/outbound round-trip (#48828)

* fix(relay): enable RELAY platform + normalize dial URL so hosted gateways actually connect

Three bugs blocked a self-provisioned hosted gateway from ever establishing its
inbound relay WS (found while standing up the live staging end-to-end). Each
masked the next; all three are needed for inbound to work.

1. RELAY platform never enabled in config.platforms (gateway/config.py).
   register_relay_adapter() puts the adapter in the platform_registry, but
   start_gateway()'s connect loop iterates self.config.platforms — which never
   contained Platform.RELAY. So the adapter was "registered" but never connected
   (logs showed "relay adapter registered" then "No messaging platforms
   enabled"). Fix: _apply_env_overrides now enables Platform.RELAY (mirroring
   relay_url into extra for the connected-checker) when GATEWAY_RELAY_URL (env)
   or gateway.relay_url (yaml) is set. Absent -> no RELAY entry (direct/
   single-tenant gateways unaffected).

2. URL scheme not converted for the WS dial (gateway/relay/ws_transport.py).
   The relay URL is configured once as the http(s):// base (used as-is for the
   provision POST), but websockets.connect rejects http(s):// with "scheme isn't
   ws or wss". Fix: _ws_dial_url converts https->wss / http->ws.

3. /relay path not appended (same helper). The connector mounts its
   WebSocketServer at path "/relay" and returns HTTP 400 on an upgrade to any
   other path. GATEWAY_RELAY_URL is the base (no /relay), so the dial hit "/"
   -> 400. Fix: _ws_dial_url ensures the path ends in /relay. Idempotent — a URL
   already carrying ws(s):// and/or /relay is unchanged, so provision's
   _provision_url (which derives /relay/provision from either form) still works.

Why the cross-repo E2E missed #2/#3: the stub connector binds ws://host:port and
its websockets.serve accepts ANY path, so neither the scheme nor the /relay path
was exercised. Real connector needs both.

Verified live on staging hermes-agent-stg-automated-perception-5054: after the
fixes the gateway logs "Connecting to relay..." -> "✓ relay connected" ->
"Gateway running with 1 platform(s)" against
wss://gateway-gateway.staging-nousresearch.com/relay, stable.

Tests: added _ws_dial_url scheme+path+idempotency cases (test_ws_transport.py)
and RELAY-platform-enablement cases for env + yaml + absent (test_config.py).
Full gateway/relay + config suites green (191 passed).

Relay-adapter lane. EXPERIMENTAL.

* fix(relay): re-attach guild_id to outbound so connector egress resolves the tenant

The final bug in the hosted-relay round-trip. Inbound worked end to end (Discord
-> connector -> bus -> agent WS -> agent runs -> reply), but the reply's egress
was declined by the connector: "discord egress declined: target not routed to an
onboarded tenant".

Cause: the connector's routedEgressGuard resolves the owning tenant from the
OUTBOUND action's metadata.guild_id (Discord's routing discriminator). The
gateway's generic delivery path builds outbound metadata via
run.py _thread_metadata_for_source, which only carries thread_id (and returns
None entirely for a non-threaded message) — so guild_id never reached the
connector, tenant resolution failed, and the shared bot refused to post.

Fix (relay-adapter-local, no perturbation of the generic delivery path or other
platforms): RelayAdapter learns chat_id -> guild_id from each inbound event
(_capture_scope) and re-attaches it to the outbound action's metadata in send()
(_with_scope) when not already present. No-op for chats we never saw inbound
(e.g. DMs) and never overwrites an explicit guild_id.

Verified live on staging hermes-agent-stg-automated-perception-5054: an
@mention in #general now produces a visible bot reply — full multi-tenant relay
round-trip (real Discord -> shared connector bot -> tenant routing -> agent WS ->
reply egress -> Discord).

Tests: _capture_scope/_with_scope reattach, no-scope no-op, explicit-guild_id
preserved (test_relay_adapter.py). Full relay + config suites green (160 passed).

Relay-adapter lane. EXPERIMENTAL.

* fix(tui): restart dashboard chat on idle exit hotkeys

* port(opentui): billing overlay, review.summary, Enter/slash fix into the engine

Ports the four TUI features deferred in the last upstream sync into the
OpenTUI (Solid) engine, on top of a fresh merge of upstream/main. No
gateway/Python changes — engine-only, mirroring the Ink behavior.

1. Terminal billing /billing — new full-screen overlay (5-screen state
   machine: overview/buy/confirm/auto-reload/limit) as net-new Solid
   components (boundary RPC types + openExternalUrl + logic/billing RPC layer
   + Solid view + store openBilling/closeBilling/patchBilling + slash /billing
   + App Match). Follows the engine's overlay conventions (picker/sessionPicker/
   agentsDashboard): state/ctx read reactively via getters (state()/ctx()), and
   theme read via useTheme() directly in each component (no theme prop-drilling).
2. review.summary — wire the self-improvement memory digest into the store
   reducer (schema already defined); honors display.memory_notifications.
3. Enter/slash-completion fix — completionMenu.acceptChangesToken gates the
   composer's Enter-accept so an already-complete command submits instead of
   being swallowed into "<cmd> " (Ink completionToApplyOnSubmit parity).
4. custom-provider session-info — verified already round-tripped; strengthened
   the test to assert a custom:<name> slug is kept verbatim.

Adversarial review (Claude Code, 2 rounds, opentui+tmux skills + a live billing
smoke harness driving the real overlay) found + fixed two billing bugs:
- AutoReloadScreen mounted EMPTY (the engine <input> `value` is init-only) —
  added value={value()} so an existing config prefills; + a captureFrame test.
- ConfirmScreen double-charge race on rapid Enter/Y — added a `paying` guard.

Gate green: 852 engine tests, prettier+tsc+eslint clean, build.mjs builds dist.
