70f5dc5f46 feat(connectors): the backend API for the desktop Connectors page; connect an app without a chat session (#115191)
* feat(connectors): the backend serves a connector's tool list, cached for 24 hours

The Connectors page opens one app and shows every tool it has. The backend
had no way to read that list.

- `tools/connectors/portal/`: a client for the portal's tool-list route and a
  JSON cache under the Hermes home, one file per portal origin and connector.
  An entry is fresh for 24 hours. After that the read revalidates with the
  stored ETag: 304 keeps the list, 404 deletes the entry, an upstream failure
  serves the stored list marked stale, and a 401 never serves the cache.
- `connectors.tools {slug, refresh}`: account-level, routed by `profile`, no
  chat session. Errors carry a fixed `reason` from one closed set on the rail.
- Every connector model that is not operation state moves into
  `tui_gateway/contracts/connectors.py`. Handlers that no chat session owns
  live in `tui_gateway/methods_connectors_account.py`.

The wire model is tolerant: an unknown facet reads as unclassified and one odd
tool never blanks a connector.

* feat(connectors): catalog, accounts and member tool rules by RPC

The Connectors page needs the app catalog, the connected account of one app,
a way to disconnect it, and the member's own on/off rules. None had an RPC.

- `connectors.catalog`: name, description, category and logo of each app.
- `connectors.accounts`, `connectors.accounts.remove`: read the accounts at
  the tool gateway and remove one by id.
- `connectors.policy.get`: the rule layers that apply to the member, widest
  first. The body is a union on `mode`, so a reader can name who turned a
  tool off.
- `connectors.policy.set`: one change, a union on `type` (the tools of one
  connector, or one connector on or off), with the revision the user saw. A
  stale revision answers `POLICY_CONFLICT`. The backend composes the upstream
  write in one pure function, so no renderer learns the upstream rules.
- Bundled MCP manifests can name their hosted twin with `connector:`, so the
  page can show one card per app.

* feat(connectors): connect an app without a chat session

Every connector RPC took a `session_id`, and a connect that did not come from
the model's tool call minted a link with no watcher. The Connectors page has
no chat session, and its card must flip to connected by itself.

- `connectors.list`, `connectors.connect`, `connectors.operation.status`,
  `connectors.operation.wake` and `connection.respond` take `owner`, a union
  on `type`: `session` (today's behaviour and authorization) or `account`
  (routed by `profile`, authorized by the live transport like `mcp.*`).
  `session_id` is gone from these params; every desktop caller sends `owner`.
- An account connect runs the same operation lifecycle on a background
  thread, under the profile's scope, so the watcher reads the account and
  settles the operation. A second connect for an app that is already
  connecting returns the open operation and mints nothing.
- `connection.update` carries `owner`. An account operation has no session to
  address, so its updates go out on the session-less broadcast path.

* feat(mcp-catalog): eighteen more bundled entries name their hosted connector

A bundled MCP entry and a hosted connector for the same app are one card
on the Connectors page only when the manifest names its hosted twin.
Linear and Notion had the field. These entries get it too: airtable,
asana, attio, calendly, dropbox, figma, railway, supabase, todoist,
betterstack, canva, cloudflare, datadog, intercom, neon, sentry, stripe
and vercel. Atlassian maps to two hosted connectors and Prisma Postgres
is not clearly the same app, so both stay without one.

* refactor(connectors): the account handlers share one gate, one params model and one write table

The six account-level handlers each repeated the availability gate, the
auth catch and the catch-all reply. One decorator now owns that, and each
handler validates its params with its contract model instead of a ladder
of isinstance checks. The five connection RPCs share one guard for the
unexpected-failure reply.

The four write composers for the member rules were the same function
with a different list key and polarity. They are one table now.

The owner union lives in contracts/common.py, so the params side and the
event side stop declaring it twice and the import cycle is gone.

An account operation start carries one event and a flag, so the wait for
the sign-in link blocks instead of polling every 50 ms. run_operation
loses its two account-only parameters; drive_operation is the second
entry point.

Tests: four deleted (they exercised pydantic or the mock), three merged
into tables, two added (a client that still sends the old top-level
session_id is refused; all six account RPCs run off the server loop).
The shared reply helper and the HTTP and managed-client fakes move to
one place each. Comments are one line or gone.

* fix(connectors): a missing tool-list route reads as "unavailable", not "connector gone"

The tool-list read treated every 404 as the portal's "this connector is
not in the catalog" answer. It deleted the cache entry and answered
CONNECTOR_NOT_FOUND, so a page would offer to remove an app that is
connected and works. A portal that does not serve the route yet answers
a bare 404 for every app.

Only the portal's own {"error": "connector_not_found"} means the
connector is gone. Any other 404 is now a tool-list outage: the cached
list is served as stale, or the RPC answers TOOLS_UNAVAILABLE.

* fix(connectors): a connect from the page returns to the app after sign-in

The sign-in link carries a return target only when the session's surface
is the desktop. A chat session binds that surface. An account-owned call
has no chat session, so nothing bound it: the link was minted without a
return target and the browser ended on the portal's done page instead of
coming back to Hermes.

Every account-owned call now runs with the process's own surface bound,
next to its profile scope. The operation thread copies that context, so
the first link and every reissued link carry the return target and the
operation id.

* test(connectors): defer the new connector RPC coverage

The tests for the new account RPCs, the portal client, the tool-list cache
and the rule composer leave this PR and come back in one later change, after
the API is settled. The same was done for #111008.

Kept: the edits that existing tests need because the five connection RPCs
now take `owner` instead of `session_id`, and the rename of the managed
client seam.

Removed: six new test files, their two fakes and the gateway conftest, and
the new cases in test_mcp_catalog.py, test_connectors_gateway_client.py,
gateway-rpc.test.ts and notifications.test.ts. Reverting this commit restores
all of them.

* fix(cli): the connection panel hands the tool thread back at once

The classic CLI's connection callback waited on a queue for the user's first
decision. The operation's watcher starts only after the callback returns, and
the watcher is what polls a hosted account, runs the 300-second deadline and
sees Ctrl+C.

For a hosted connector the panel opens on the sign-in link, where the only
key that filled the queue was Cancel. The account was never polled: the user
signed in, the panel never changed, and Esc reported the app as skipped.
Ctrl+C set the interrupt flag but left the thread parked on the queue, so the
turn never ended.

The callback now opens the panel and returns, as the gateway's callback does
for the desktop and the Ink TUI. The panel's actions already reach the
operation through apply_answer on the UI thread, so the queue is removed. An
install with a form still waits for Connect, because the backend starts no
work for a pending row. Ctrl+C now settles the operation as `interrupt`, and
open rows become `not_connected`.

Checked on the e2e rig with the fake tool gateway: hosted connect completes on
the third status read; Ctrl+C ends the turn and the polling stops; an MCP
install with a plain and a secret field still saves config and both values.

* fix(connectors): "run it again" lives in the library, so the classic CLI can use it

Making a new sign-in link for a failed or expired hosted connector was
implemented only in the JSON-RPC layer (`_reissue`). The classic CLI does not
go through JSON-RPC: its Connect button on a failed row called apply_answer,
which does nothing for a hosted operation because it has no MCP runner. The
panel showed "Waiting…" until the deadline.

`tools.connectors.run.reissue(operation, names)` now holds the checks and the
per-kind action, and returns a refusal reason or None. The gateway maps each
reason to the same JSON-RPC error as before. The CLI calls it for a hosted
row; a refusal is shown on the row. MCP rows keep their path, because Connect
on a failed MCP row re-sends the form values.

Checked on the e2e rig: a scripted failed sign-in, then Connect: a second mint
with `reinitiate: true`, a new link with a new connection id, then connected.

* feat(connectors): the account list and disconnect go through the portal

`connectors.accounts` and `connectors.accounts.remove` called the tool
gateway. They now call the portal's account-management routes
(`GET /api/v1/connectors/accounts`, `DELETE /api/v1/connectors/accounts/{id}`),
which apply the organisation membership checks and write the disconnect audit
row. There is no fallback to the gateway when the portal is unavailable, and a
removal is never retried.

The read of ONE account stays on the gateway (`GET v1/connectors/accounts/{id}`):
the portal has no such route, and the operation watcher polls it once per second.

`ConnectorClient.list_accounts` and `delete_account` are removed. The removed
account's reply model carries `connector`, which both services send.

* fix(connectors): the account RPCs answer what the portal really sends

Checked against the portal source and against the staging and production
services.

- Errors are read from the upstream error code, not the HTTP status. A rule
  write answered 409 for a stale revision and for a user with no organisation;
  both read as "the policy changed". `org_required` is now `ORG_REQUIRED` and
  403 `no_access` is `ORG_ACCESS_DENIED` on every account RPC; only a rejected
  sign-in is `NEEDS_NOUS_AUTH`. `connectors.list` and `connectors.connect` with
  the account owner map these too.
- `connectors.policy.get` and `connectors.policy.set` carry `effective`: the
  portal's own result for this user, with its stamp and without provider or
  subject ids. Nothing is recomputed locally.
- A rule write needs the revision the user saw: `expected_revision` is required
  and must be a revision string; a bad one is refused before any HTTP call.
- A tool row carries `no_auth`; a list without the upstream flag is an invalid
  answer, not `false`.
- `connectors.accounts.remove` returns the app of the removed account. An
  invalid id is `INVALID_PARAMS`.
- The tool-list cache is per signed-in member (a hash of the token's `sub`),
  so two Nous accounts on one profile do not share entries.
- A malformed slug is a local error, not a 404 from a server nobody called.

Live, staging: no revision and a malformed revision refused locally; a good
revision wrote one disabled Gmail tool and returned it in `effective`; the
same revision again answered `POLICY_CONFLICT`; the list row showed the tool;
the restore brought the member rules back to the start. Live, staging and
production, read-only: all 60 tool lists (5483 tools) parse.

* fix(connectors): the operation RPCs match their contract; a settled card cannot start a new link

Found by two adversarial reviews of the RPC layer and its types.

- `connectors.connect` from a chat session with no open operation is refused
  (`UNKNOWN_OPERATION`). It used to call `manage_connections` through the tool
  registry with no card: it made a link nobody watched, returned a reply
  without the required `settled` field, and named an operation that was never
  registered. There is one way into an operation: the agent's call, or the
  account owner's `connectors.connect`. "Run it again" inside an open
  operation is unchanged.
- `connection.update` for a session is routed by session key AND profile; two
  profiles with the same key no longer cross-deliver a sign-in link. The event
  payload gets the same redaction as the RPC replies.
- `connection.respond` runs on the long-handler pool: an approval can start MCP
  OAuth discovery, which blocked every RPC of the gateway while it ran.
- `connectors.list` rows are a closed snake_case model: `connector`, `enabled`,
  `connected`, `connection_status`, `status_reason`, `gateway_disabled_tools`.
  The last one is display data: the gateway enforces the rules, the backend
  only passes the list on. The phantom `name` and `description` are gone, and
  the desktop uses the generated types instead of hand-written copies.
- `tools_listing` (model-only data) no longer rides on `connectors.operation.status`.
- `unavailable` is removed from the target states and settle reasons: nothing
  produces it. The contract generator now fails when a contract enum and its
  domain enum differ.
- `ConnectorErrorReason` is part of the generated TypeScript and OpenRPC.
- The desktop sends `connection.respond` on the socket that holds the session,
  as wake and reissue already did.
- Contract violations are logged every time, at error level.
- An account connect whose prepare step is slow returns the live operation
  instead of an error while the operation keeps running.
- The MCP-manifest `connector` field leaves this PR (it moves to a later one
  on top of the catalog-reader change). `hermes_cli/mcp_catalog.py` and
  `optional-mcps/` are untouched by this PR again.

anti-slop: no net-new findings (15 touched files).

* fix(connectors): the model gets no sign-in link wherever a card exists; side agents cannot connect

The flag that tells the model "a connection card exists" was the session
platform (`== "desktop"`). The Ink TUI and the classic CLI also draw a card,
so there a connector call on an unconnected app handed the model the raw
`connect_url` and told it to pass the link to the user.

- The agent turn now declares how a link can reach the user
  (`tools/connectors/turn.py`): CARD when the agent was built with a
  connection callback, SIDE for a subagent or a background turn, LINK for a
  headless run (`-q`, cron, ACP, api_server, messaging). It is set once per
  tool batch in the agent loop and read by the connector dispatch path, which
  never sees the agent. The session platform decides return-to-app only.
- CARD: the result carries `connect_card_available` and our hint, never the
  link and never the gateway's own hint.
- SIDE: subagents (`delegate_tool`), gateway background turns and the classic
  CLI `/bg` are built with `side_agent=True`. They hold no `manage_connections`
  tool on any path that derives the tool list, and a connector call on an
  unconnected app gets no link, only "report this to the main agent".
- LINK is unchanged.
- The hosted path with no card builds a detached operation, as the MCP path
  does, so no `connection.update` is emitted for an operation no client asked
  for. Names and docstrings that said "off desktop" now say "no card".
- A settled card is dead on the desktop: `reissueConnectionTarget` and
  `respondToConnectionRequest` share one guard and send nothing for a settled
  or unknown operation.
- The model-facing settled result no longer carries `connection_id`; the model
  repeated it to the user.

Shown on the real clients with a real model (rig, fake tool gateway): Ink TUI
and classic CLI get `connect_card_available` and no link, the model opens the
card, the account connects, the retried call succeeds; `-q` still gets the
link; a subagent and a background turn have no `manage_connections` and get
the no-link hint; on the desktop a card settled with Continue has no enabled
control and sends no RPC.

* feat(tools): every call made through tool_search + tool_call shows a real label on all three clients

A bridged call showed as a generic `tool_call` row in the Ink TUI and as
`⚡ tool_call` in the classic CLI, because the display looked the name up in
the tool registry and bridged names are made at run time. The desktop labelled
only batches that were all hosted connector calls, by parsing names itself.

- `tools/tool_labels.py` is the one place that turns a bridged call into a
  label: kind, app, action, emoji and text. Hosted: `connectors__gmail__GMAIL_SEND_EMAIL`
  → "Gmail · send email". MCP: "Linear · list issues". A local deferred tool
  keeps its own emoji, verb and primary-argument preview. A batch gets exactly
  one label per entry, always; an entry with no name gets a generic label.
- Classic CLI: one row per inner call; the duration on the last row; the
  failure text on the row of the call that failed. With friendly labels off
  it prints what it printed before.
- Gateway: tool start, progress and complete events and stored transcript rows
  carry a typed `labels` field. It does not depend on the classic CLI's
  display setting. Clients no longer parse tool names.
- Ink TUI: rows from the labels; the verbose trail keeps Args and Result.
- Desktop: `ConnectorExecution` renders hosted, MCP and mixed turns from the
  labels, one row per call. The labels reach the row under a key no tool
  argument can use. The connect card it drew under a failed tool result is
  gone: after `CONNECTION_REQUIRED` the one way in is the agent's own
  `manage_connections` call.
- `tool_search` and `tool_describe` rows read "Searching tools · <query>" and
  "Reading tool details · N tools".

Shown on the real desktop (video and screenshots), the Ink TUI and the classic
CLI with the rig: hosted rows, MCP rows, a two-entry batch, a failed entry, a
`CONNECTION_REQUIRED` row with no card under it, labels after a reload, and the
desktop rows with the classic CLI setting off.

* fix(connectors): the model can tell "hosted tools unavailable" from "no such tool"; manage_connections routes MCP names correctly

- A failed hosted search or describe used to return nothing, by design, so the
  model saw only local tools and told the user that a connected app was
  missing. The local results are unchanged; when the hosted leg failed, the
  `tool_search` and `tool_describe` results carry
  `connectors: {status: "unavailable", reason: "unreachable" | "sign_in_expired"}`
  and one hint line. A rejected token is `sign_in_expired`; an entitlement
  refusal or a shut gate adds nothing. `tool_describe` no longer lists those
  names under `not_found` next to "search again".
- NS-932. The description now says which side a name belongs to: a bare name
  is a hosted connector account; `mcp: true` only when the user asks for an MCP
  server, a local server or an install, or when the name exists only in the
  catalog; connect and reconnect are hosted verbs, install, enable and
  authorize are MCP verbs. It names the three clients that draw a card.
- A misrouted target is refused with the call that works. Only when the
  gateway does not know the connector (confirmed on that failure path) and the
  name is a catalog entry does the target fail with "X is a local MCP server.
  Call manage_connections with action install ...". It is a per-target
  outcome: other targets of the same call keep their links and their card. A
  vendor failure on a name both sides know stays an ordinary failed row. The
  MCP side mirrors it, and never for an entry that is only not installed.
- "Do not re-ask after a skip or a timeout" no longer stops the model when the
  USER asks for that app again; the description and the settled-result notes
  say so. A builder saw the model refuse a direct user request.

Shown on the Ink TUI and the classic CLI with a real model: a dead gateway and
a 401; "connect fxmail" goes hosted; "install the fx-noauth MCP server" goes
MCP; "connect fx-noauth" reaches the MCP install card in one corrective round
with no hosted mint; a two-target call where one is misrouted still connects
the other with exactly one mint.

* fix(tui): the connection card answers every key, shows what is happening, and is dead once settled

Reproduced on the real Ink TUI with the rig, then fixed:

- The keyboard was dead during the sign-in wait: the card kept a `submitting`
  flag that the normal OAuth path never cleared, and Esc went through the same
  guard. The in-flight state now belongs to the answered row and clears when
  that row moves, when any later frame of the operation arrives, or after
  five seconds. Esc skips the row in every phase; Ctrl+C interrupts the turn
  (the input handler had no branch for this overlay); Shift+arrows scroll the
  transcript and the card ignores them; arrow keys no longer move the text
  cursor and the field focus at once.
- The card was lost at turn idle: the overlay flag was cleared while the
  operation stayed in the store, and a resume dropped the pending card. The
  flag survives idle, a resume shows the pending card again, a session switch
  clears it.
- States with no branch: `not_connected` and a row with no link fell into the
  credential form; `expired` vanished with no note. The title and the row text
  now name the action (connect, reconnect, install, enable, authorize); a
  failed or expired row with no fields offers Try again / Skip; a failed row
  WITH fields reopens the form over the typed draft, with the failure above it.
- A settled card is dead: at settle the overlay closes and one transcript line
  per app states the outcome. A settled or dismissed operation id is
  remembered, so no replay or resume can reopen its card. Esc in the last
  "Finishing…" moment hides the card and still writes the outcome lines.
- A failed `connection.respond` and a browser that did not open are shown on
  the card in one sentence.

Also: `tui_gateway/connector_payload.py` redacted the BOOLEAN `secret` flag of
a credential field to the string "[REDACTED]". On the desktop every credential
field therefore rendered as a password and lost its prefilled default. A
boolean is no longer redacted.

* chore(connectors): remove the comments and docstrings this branch added

Deletions only. Kept: tool directives (`# noqa`, `// eslint-disable`, ...),
`// SAFETY:` lines, and the docstrings of the contract models under
`tui_gateway/contracts/`, which become the descriptions in the generated
OpenRPC and TypeScript.

Checked that no code changed: every Python file has the same AST as before
once docstrings and `pass` are ignored (62 files), and every TypeScript file
prints the same with comments stripped by the TypeScript printer (32 files).
The generated contract files are unchanged.

* fix(connectors): a card restored after a reload answers again; every account RPC names auth and org failures

Found by the end-to-end runs on the pushed head.

- Desktop: after a window reload, Continue on the restored card sent nothing.
  The answer looked up the backend that holds the session with the runtime
  session id, the lookup wants the stored id, and a failed lookup returned
  silently. When the lookup gives no owner the answer now goes out on the
  window's active socket, which is what main does.
- `connectors.policy.get` answered `POLICY_UNAVAILABLE` for a rejected sign-in,
  a refused scope, a non-member and a missing organisation alike: the handler
  runs with the gateway's globals and did not import the reason enum, so its
  own error mapping raised. `connectors.accounts.remove` caught auth failures
  in its generic branch. `org_required` was mapped on `policy.set` only. All
  six account RPCs now answer `NEEDS_NOUS_AUTH`, `FORBIDDEN_SCOPE`,
  `ORG_ACCESS_DENIED` and `ORG_REQUIRED` for those four upstream answers.

afc3b7c6f3 feat(connectors): one backend-owned connection operation, with a setup card on Desktop, TUI and CLI (#111008)
* feat(connectors): the desktop connects apps through one backend-owned operation

Re-based onto main after #109517, #110368, #110574 and #110843 landed as squash
merges (e0ef0eb9c3, d105376b21, ee2f5629b8, 1ab32b212b): the branch's history
no longer shared a base with main, so this is the PR's exact delta against
+3762/-1470, identical to the branch tip 05d7f2d3d5.

The fifteen commits it carried, in order:

--- feat(connectors): the wire follows the connector contract (six-state status, required toolkit metadata, connectionId on mint)

Hermes types exactly what the contract page writes: /tmp/magic/CONTRACT-TOOLKIT-METADATA.resolved.md
(carriers: portal PR2 `sid/connection-api` for the enum and account rows, the portal contract branch
on top of it for the list metadata). No optional-for-compat fields, no fallback branch, no seven-state
word left in the tree. A gateway that does not speak this contract fails validation loudly.

Wire (tools/connectors/gateway/wire.py): `ConnectionStatus` is the six values, `pending` covering the
vendor's INITIALIZING and INITIATED; `ConnectorListItem` requires title, description, https iconUrl and
authKind, and carries activeConnectionId when the session binds an account; `ConnectorListResponse`
types a page whole with its total; `ConnectorAccount` and `ConnectorAccountsResponse` type the account
routes; a mint result names its connectionId on `initiated` and never on `failed`; CONNECTION_REQUIRED
carries connectUrl and connectionId together or not at all; `account` exists on the execute call and is
never sent while multi-account is off.

Client: `list_connectors(search, connected)` refuses a search under three characters before any
request and parses every page whole; `list_accounts` and `account_status` read the account routes,
404 `connection_not_found` is None and 429 raises `RateLimited(retry_after)`.

Watcher: the target keeps the account id the mint named and the toolkit's title and icon from one
list read before the card is emitted; `_status_for` is the one seam between the watcher and the
gateway's status source (the list walk today; the per-account route replaces that body only).
`pending` and a missing status move nothing; revoked and inactive are failed.

Desktop: `ConnectorRow` is the strict list item; `ConnectorRowSeed` is what a tool call's args can
say; `connection.request`/`update` targets carry `connection_id`, `title`, `icon_url`; the mark
ladder is glyph, vendor icon as a plain image, favicon, monogram.

Tests run red first: wire rejects the retired words and the missing metadata; client search
minimum, execute omits account, account_status 404/429; managed targets carry the metadata and the
account id, a pending row moves nothing; the logo ladder order; the store passes the fields through.

--- feat(connectors): onboarding connect-first rides the connection operation

The guided first build had its own connector surface: a 2 s connectors.list poll loop, an auto-open
of every minted link, a hidden "[setup] links opened" note that painted as a user bubble, CONNECT
FIRST rows in the transcript, and a "Start with N apps connected" composer pill that sent the go
signal early. Delete all of it. The build session's first manage_connections connect now shows the
same card as any chat, and the settled tool result is the go signal.

Deleted: store/first-build-connectors.ts, assistant-ui/first-build-connectors.tsx (nothing rendered
it any more), lib/first-build-start.ts, onboarding-chat/start.tsx, the first-build session markers in
handoff-receipt.ts, the connectionRows / latestConnectorPart helpers they were the last readers of,
and the five strings only they used.

The runbook (setup-profile.ts::connectFirstRunbook) now describes the operation's real contract: one
connect call with every picked slug, one card with a row per app, blocks until settled, a per-app
result of connected / skipped / not_connected. No wait, no "Start with", no "already active" branch
(the result never carried it), and no offer to re-mint: Try again and Continue live on the card, and a
Continue means the user moved on.

Tests (red first): the runbook names one connect call and its per-app result and never the retired
model actions; the no-account rule survives an empty pick.

--- feat(connectors): the registry is keyed by profile, every watch read is bounded by the deadline, connectionId is optional, connect and execute carry returnTo and op

Registry (P1-14): tools/connectors/live.py keys an operation by (profile home, session key). Two multiplexed
profiles can carry the same timestamp-based session key; the tool thread opens under its turn's profile
override and the RPC side names the session record's profile home, the default profile resolving to the
process home on both sides.

Watch reads (P1-8 residual): list_connectors takes a per-page timeout and the watcher bounds each read by
the operation's remaining deadline (floor one second), so a stalled gateway page cannot hold the operation
past its deadline.

Contract follow-up from the portal handoff (/tmp/magic/HANDOFF-HERMES-PR3-PORTAL-CONTRACT.md): connectionId
on a mint result and on CONNECTION_REQUIRED is plain Optional (a no-auth toolkit answers active with none; a
failed mint answers with neither link nor id); a target without one has nothing to watch. Connect and
execute requests carry returnTo (hermes-desktop | hermes-desktop-dev | portal) and op, so the vendor's done
page can send the browser back to the app; the call sites and the deep-link handler follow in the next
commit.

Tests, red first: two profiles share a session key without seeing each other; each watch read shrinks with
the deadline; the client honours a per-page timeout; the optional id; the two request fields. The fakes'
list_connectors accept the timeout keyword; two wrapper spies that did not were the cause of a 300 s hang
under the per-file harness.

--- feat(connectors): an MCP target runs on the shared connection operation

manage_connections ran MCP targets as a renderer errand: the desktop card ran
the catalog lookup, the install and the OAuth flow, then told the backend what
had happened, and every surface without a card got `unavailable` plus two
terminal commands. That left the outcome in the renderer's word, and left the
model unable to connect an MCP server anywhere but the desktop.

The backend now owns the work, the way it already owns a managed connector.
`prepare` starts the OAuth flow in process and points the browser at the
backend's own callback route; an install that still needs credentials waits
pending and publishes their names as `required_env`; `observe` reads the flow
or the install worker on every tick. The worker itself moved out of
tui_gateway/mcp_oauth_sessions.py into tools/connectors/mcp_oauth.py, and that
module now calls it, so the Capabilities tab keeps its RPC session table.

The card may only say approved, skipped or continue: a claim of any other
state moves nothing. With that, `renderer_flow` and the `unavailable` state
have no producer left and are gone from the contract. Off the desktop there is
no card, so the action runs at once and the result carries the authorization
URL for the user to open.

Try again reaches the same work: `_reissue` dispatches on `target.kind`, so an
MCP row re-runs its own install, enable or OAuth instead of minting a managed
gateway link.

--- feat(connectors): the MCP card projects the operation instead of running the flow

The MCP setup card used to own the work: it called the catalog, ran
installMcpCatalogEntry, polled the action, drove the OAuth window, and then told
the backend what had happened through connection.respond. That made the renderer
a second authority on target state, so an install that finished after the window
closed, or a card that never mounted, left the operation with a state nobody
could correct. PR3 moves that work to the backend, so the card has one job left:
show the operation and send the user's consent.

McpSetupPending now renders request.targets the way ConnectorOffer renders them:
one row per target, one verb by (action, state), Continue below the shell.
Install and Enable send {status: 'approved'} and nothing else; an authorize row
opens the link the backend minted, with no OAuth RPC of its own; a running
install holds its verb with the busy mark; a failed row sends
connectors.connect {reconnect: true} on the open operation, the same call the
managed card makes. The owner lookup and that call are now shared helpers on
connector-tool.tsx rather than a second copy here.

ConnectionTargetOutcome loses connected / initiated / failed: those were the
renderer reporting state, which it no longer may do. ConnectionActor loses
renderer_flow for the same reason. ConnectionOperationTarget gains required_env,
the credentials an MCP install is still waiting for; the card renders a field per
entry under the pending row and holds Install until every required one has text,
so the values travel with the approval instead of through a separate catalog call.

--- fix(connectors): the toolkit metadata leaves the wire; the vendor logo is derived from the slug

Sid cancelled portal PR3 (the toolkit metadata on the list item) on 2026-09-14, so the fields the contract
commit typed as required come off the wire: no title, description, iconUrl, authKind or activeConnectionId
on the list item, no total on the page, no search or connected query, no title or icon_url on a target
snapshot. The list item is exactly what portal #1220 emits.

The desktop derives the vendor logo from the toolkit slug instead (`connectorIconUrl`,
https://logos.composio.dev/api/{slug}; the gateway slug is the vendor slug, checked for every lead-order
pick), rendered as a plain image because the host sends no CORS header. The title stays
`connectorTitle(slug)`. The mark ladder is unchanged: glyph, derived vendor icon, favicon, monogram.

Everything else in the contract stands: six-state status, optional connectionId on mint results and on
CONNECTION_REQUIRED, returnTo and op, the account routes. The contract commit's message still names the
metadata; this commit is the correction.

--- fix(connectors): an MCP target survives the card's Continue, and the model is not sent to an action that refuses it

The review of the MCP backend found eight defects; each one is a test first.

- The off-desktop note told the model to confirm with action 'status', which refuses MCP
  names outright. It now says the authorization finishes in the background and the tools
  arrive on the next turn.
- The card's existence is a property of the session. A missing callback no longer routes a
  desktop session down the off-desktop path, where the model would be handed a live link.
- A second failure of a backend attempt was published with actor 'user'. ``refresh`` takes
  the actor, so the frame says who produced the text.
- Continue on the RPC thread can settle the operation between any read of a target's state
  and the transition that follows it. A settled operation has a frozen result, so the lost
  move is dropped; an IllegalTransition no longer escapes into the tool result. The same
  rule covers a worker whose outcome arrives late and a Try again that arrives after Continue.
- Try again on an install carried no credentials, so the second install ran with an empty
  env. The approved map is kept on the runner (never on the target: target fields are
  serialised to the model) and reused.
- An approval that does not cover a required credential no longer reaches the worker, where
  ``install_entry``'s prompt would block on stdin forever; the row waits for the card's
  fields instead.
- ``enable`` writes ``mcp_servers`` under the scope and lock the dashboard's toggle route
  uses, so the two read-modify-write paths in one process cannot drop each other's write.
- Several authorize targets start their flows together and share one wait; one wait per
  target kept the card empty for minutes.
- The off-desktop operation is in no session's registry, so it now emits no connection.update.

Try again is also refused for a target the transition table cannot move back to 'initiated'
(an MCP target has no move out of 'expired') and for an operation that settled during the call.

The contract test that froze the Actor enum is replaced by two behaviour tests: no actor but
the backend watcher can connect an MCP target, and the card's word never moves one.

--- fix(connectors): the watcher reads one account route per target, and every frame carries its seq

The watch loop walked the whole toolkit list once per tick to learn whether one
target had connected. That read costs a vendor call per page, cannot tell one
account from another, and forced `awaiting_new_attempt`: after a forced
reconnect the list still reported the OLD account `active`, so the row had to be
disbelieved until it read as something else once. The gateway now serves
`GET /v1/connectors/accounts/{connectionId}`, so each pending target reads its
own account: the id the mint named, one read per target per tick at 1 Hz (the
route's bucket is 180/min per principal), each bounded by the operation's
remaining deadline. A 429 parks that one target until its Retry-After passes and
leaves the others reading. A 404 is "not yet" until the deadline. A target the
mint gave no account for has nothing to read, so it is not read. A forced
reconnect watches the new account, which is why `awaiting_new_attempt` and its
two tests are gone.

`mint` and `run_remote` now name where the browser should come back to
(`returnTo`, plus the operation id on a mint), so the vendor's done page can
hand the user back to the desktop app that asked instead of stranding them on a
web page. Only the desktop registers that URL scheme, so no other surface sends
either field.

`connection.update` frames were built by re-reading the operation after the lock
was released, so a second writer could give an older frame a newer state and the
renderer could not tell which frame was last. Every write now advances a
monotonic `seq` and takes its snapshot under the same lock, and the emitter sends
that snapshot; a renderer that keeps the highest seq per operation can drop a
frame that arrives out of order. `connectors.operation.wake` lets the desktop's
deep-link return ask for a read now instead of at the next tick; it only shortens
the wait and trusts nothing else in the link.

(cherry picked from commit f5423cf72302b92b26c043495184ad6426fa2b36)

--- fix(connectors): the desktop card follows the operation, and says so out loud

The MCP card was a second implementation of the connector card with the
review's defects: it painted for any request on the session, kept its
controls after the operation settled, offered an approve verb while the
backend was still minting an authorize link, and re-enabled Install when
the RPC returned rather than when the state frame moved the row. A second
click in that window sent the consent twice.

The renderer now reads the operation's `seq`: an update or a status frame
whose sequence is not greater than the one already applied changes
nothing, and a resume snapshot neither revives a settled card nor puts
back a row a newer frame has moved. Without it the transport's ordering
decided what the user saw.

`hermes://connections/done?op=…` brings the user back from the browser to
the session that opened the operation and wakes its watcher, so the row
moves at once instead of at the watcher's next tick. Only the op id is
used; the link's status moves no row.

Each row's mark and cue are one polite live region, so a row that flips is
heard and not only seen, focus follows the row the backend moved while the
card holds it, and the waiting mark stops spinning under reduced motion.

(cherry picked from commit 7c30d252556d7d496ddb354b50bcecc41bceef27)

--- fix(connectors): the renderer types seq as the wire carries it

The watcher commit made `seq` a required field on every operation frame. The
desktop store still declared its own optional `seq` so it would compile against a
backend that predates the field; that backend no longer exists on this branch, so
the hedge is dead code and the fixtures were short one field. The store now reads
`seq` from the shared types, and the fixtures count the way the backend does.

The repeat-frame test asserted the whole request keeps its reference. With a real
rising `seq` the request must change; the invariant the test guards is that the
target row keeps its identity so open credential inputs do not remount.

--- fix(connectors): a URL that arrives after the shared wait still lands on its row

The shared prepare wait failed every row still pending when it ran out, while
that row's own thread was still waiting on the provider. When the URL arrived a
moment later the thread's move raised inside the daemon thread, the link was
lost, and Try again started a second flow. The wait now bounds only how long
prepare blocks; a row still pending afterwards is left to its own thread, which
is the only writer of that row and ends with the URL or the flow's own failure.

The comment on the approved credentials said every target field is serialised to
the model; it is not (the snapshot names its keys). The reason they live on the
runner is that they are secrets and the runner's life is exactly the operation's.

--- fix(connectors): the review findings the operation must survive before the fold

The MCP prepare threads and the install worker started with an empty context,
so a named-profile turn's home override never reached them: the flow resolved
the process home's `mcp_servers` and stored the token there. Each thread now
runs in a copy of the calling thread's context. `connection.respond` had the
same gap on the RPC thread: an approval ran the enable, which writes
config.yaml, with no profile bound, so the flag landed in the launch home. The
handler binds the session record's profile the way `_connector_rpc` does;
`config_write_scope(None)` keeps that override, so the enable needs no change.

The watcher raised out of the tool when a per-target Skip landed while that
target's read was in flight: the operation stayed open with `live` closed, and
every later answer got 4004. A read for a row that is no longer live is dropped
at debug; only a refusal on a live row is still a contract violation. The same
skip from the card raced a row the backend had just connected and aborted the
rest of the answer; a skip for a resolved row is ignored and every entry, then
the settle check, still runs.

A read was bounded by the whole remaining deadline, so a hung gateway held the
first read for 300 s and Continue could not return the tool; a read now waits
ten seconds at most. A 429 parked only the target that read, but the budget is
the principal's, so the next target's read in the same tick spent it again:
every live target waits out the one Retry-After.

The MCP surface rule read the platform alone, so a desktop call without the
callback (registry dispatch from execute_code) opened an operation nobody
rendered and blocked for the deadline; it now uses the managed rule, surface
and callback. A write after settlement advanced `seq` while emitting the
frozen frame, so the resume snapshot named a seq no frame carried; the counter
stops at the settle frame. A mint that reports `initiated` with no account id
logs that the watcher cannot read the row.

--- fix(connectors): the desktop card holds a verb until the backend answers, and never takes the keyboard from a credential field

The review of the desktop card found five defects; each one is a test first.

- A resume snapshot was refused whenever the cache held a settled operation, whichever
  operation it was, so a session that opened a second operation after settling the first
  never got its card back from a resume. And the refused snapshot handed the caller the
  settled cache as "the request", so the session was flagged as needing input behind a
  summary with no controls. Only the same operation can refuse the snapshot now, and a
  refused one is no pending card.
- The focus handoff picked the row's first button, which after pending -> initiated is the
  disabled working verb; the focus call was a no-op and the keyboard landed on the document
  body. It picks the first control that can take focus, else the row. It also moved focus out
  of a credential field the user was typing in whenever another row moved; it leaves an
  editable alone. The "focus Continue once every row resolved" branch was dead (Continue
  unmounts the moment nothing is unresolved), so it and its ref plumbing are gone.
- The done link navigated to a settled operation's session and rejected when the wake RPC
  did (4004 once the operation left the live registry). A settled request is ignored, and a
  refused wake is nothing: the wake only shortens the wait, the watcher still ticks.
- Install spun forever when the store refused to send the consent (the operation gone or
  settled under the card): `respondToConnectionRequest` resolves false in that case and the
  verb was only released in `catch`.
- After a partial approval (a required credential missing) the backend answers with a
  same-state frame whose detail names what is missing; nothing released the verb because it
  was held until the row's state moved. The row now remembers the seq the click saw and holds
  the verb only until a frame past it arrives, which is the backend's word on the click
  whether or not the row moved.

(cherry picked from commit 4c534d6e2af979778d9a2423cf97d717edeaa1a9)

--- fix(connectors): a skip that loses the race to the watcher is ignored, not raised

The skip guard read the row's state and then moved it; the watcher can connect the
row between the two, and the refused move aborted the rest of the card's answer.
The refusal itself is now the witness: a move refused for a row that is resolved,
or on a settled operation, is the same nothing-to-do as a row resolved earlier.

Two recording fakes in the managed tests kept their lists on the class; they now
start per instance so a lifted fake cannot share reads between tests.

--- fix(connectors): a resume that lands behind a newer live frame still reports the pending card

The refused-snapshot branch answered "no pending card" for both reasons it can
refuse: the operation settled, or a newer frame already moved a row. Only the
first is no card. For the second the live card is still open and blocking the
turn, so the caller must keep the session flagged as waiting on it.

* test(connectors): defer new connection coverage until implementation settles

Remove PR-added test cases and their unused helpers while retaining
existing tests adapted to the changed connection contract. The three
PR-only renderer test files are removed for now.

Focused behavioral coverage will be added as the final implementation
step before verification. Existing main coverage is not being removed
wholesale, and this does not declare the feature merge-ready.

* fix(connectors): commit MCP authorization at initialize, save setup values after success

The OAuth probe treated one exception as one outcome: any failure after the browser
step restored the token snapshot and manager entry, so a server that accepted the
token but failed tools/list discarded a completed consent. Now the probe reports
whether initialize succeeded (details["initialized"], read from the claimed
MCPServerTask). Failure before that point rolls back as before. Failure after it
saves the server config, keeps the tokens, and reports tools unavailable through
flow.discovery_error; the card can retry discovery without repeating consent.

Catalog install wrote the submitted values to .env before install_entry and the
probe ran. The values now live in the secret scope for the duration of the install
(get_env_value reads through get_secret, so install_entry finds them without a
prompt), and .env is written only after the probe returns tools. A failed probe
removes the server block and writes nothing. _probe_tool_names returns None on a
failed probe instead of an empty list, so failure and a valid empty listing are
distinct.

Failure text is redacted before it reaches target detail: every value the card
submitted for that target is replaced by exact match, then the pattern redactor
runs.

required_env now carries the manifest's secret and default flags; Target carries the
manifest's post_install text as instructions. The wire contract gains secret,
default, instructions and discovery_error; generated TS and OpenRPC regenerated.

* fix(connectors): one OAuth callback receiver picker for the connection card

The card's authorize target built its redirect from the dashboard web server and
raised when none was bound in the process, so a standalone hermes --tui session
could never authorize an MCP server. The receiver is now chosen in one place
(choose_callback_receiver): a pinned pre-registered client keeps the SDK's own
listener on the registered port; a client-advertised loopback URI is used as-is and
its callback arrives through the mcp.servers.oauth.callback relay; otherwise the
backend binds a one-shot loopback listener and feeds it into the flow. The dashboard
route stays with the dashboard web page, which cannot bind a port.

tui_gateway/mcp_oauth_sessions.py had a second copy of the loopback listener and a
_worker that referenced _probe_with_rollback, set_hermes_home_override,
reset_hermes_home_override and Path without importing them, so every RPC-started
flow raised NameError. Both are deleted; start_flow spawns run_worker directly and
uses the same receiver picker. Flow registration is shared (register_flow /
finish_flow) so a card-started flow with a client URI is reachable by the relay.

Under an SSH session with no client listener the attempt's detail carries the
existing paste-the-redirect instructions. Nothing on the card path opens a browser.

* feat(desktop): setup-form modal for MCP connection cards

The connection card rendered an MCP server's setup fields inline: every field as a
password input, no default value, no instructions. A URL such as the n8n MCP
server URL was typed blind, and the manifest's setup text never reached the user.

Two components carry the form now. SetupFieldList renders the ordered fields the
backend declares (a plain field as text prefilled with the manifest default, a
secret field masked and empty). SetupFormDialog composes it with a one-line title,
the manifest instructions, an inline error for a failed attempt, and Cancel /
Connect. The row's Install action opens the dialog when the target has fields;
Connect sends {status: approved, env}; Cancel sends {status: skipped}. A failed
attempt keeps the dialog open with the draft intact. The draft lives in the dialog
component only; nothing reaches the store or the resume snapshot.

Once the backend publishes the authorization URL the dialog shows it as text with
an Open in browser button. Nothing opens a browser on a state change: the Try
again path on both cards used to open the re-minted link at once; it now waits for
the row's update frame and the user's click.

The store types gain the wire's secret, default, instructions and discoveryError
fields and normalise them; a connected target with discoveryError renders as
authorized with tools unavailable.

* feat(tui): connection card in the Ink TUI

The Ink TUI had no client for the connection operation: connection.request,
connection.update, connection.respond and the pending_connection resume snapshot
were unhandled, so a manage_connections call in a TUI session could only print a
link through the model.

connectionOperationStore.ts holds the backend snapshot: a request opens only for a
new operation id, an update applies only to the live operation with a higher seq,
a settled update freezes the id so a late request frame cannot reopen the card.
The gateway event handler feeds it; session resume hydrates it from
pending_connection.

connectionSetupOverlay.tsx renders one callout in the prompt zone: a one-line
title, the manifest instructions, every field (plain rows prefilled with the
default, secret rows masked), then a Connect / Cancel selector. Connect sends the
draft through connection.respond; Cancel skips the active target. When the backend
publishes the authorization URL the callout shows it as text under "Press Enter to
open in browser"; Enter is the only thing that opens it. A failed attempt unlocks
the fields with the draft kept. An accepted secret renders as "Set" and is never
echoed. A target authorized without tools shows that state and Continue.

The overlay joins the existing input-owner set in overlayStore so typing and other
prompts are blocked while it is up.

* feat(cli): connection panel in the classic CLI

The classic hermes CLI passed no connection_callback, so a manage_connections
call could only print an authorization link through the model and could not take
a setup value at all.

The CLI now renders the connection operation as a prompt_toolkit panel, on the
same queue mechanism as the clarify panel: the agent thread's callback opens the
panel, blocks until the first decision, then returns so the operation's watch loop
runs; every later state reaches the panel through ConnectionOperation.on_change
(installed only when no gateway hook is set, restored on close).

Panel: one-line title, the manifest instructions, one row per field (plain rows
prefilled with the default, secret rows masked in the input buffer and rendered as
"Set" once accepted), then Connect / Cancel. Connect sends the draft through
apply_answer; Esc skips the active target; Ctrl-C sets the tool-thread interrupt so
the operation settles as interrupted. Once the backend publishes the authorization
URL the panel shows it with the target detail and "Press Enter to open in browser";
Enter is the only thing that opens it. A failed attempt unlocks the fields with the
draft kept; an authorized target without tools offers Retry discovery / Continue.

Up/Down move between rows, Left/Right toggle the action, and the panel joins the
blocking-overlay guards so chat input, history and voice stay out while it is up.
The single-query (headless) mode passes no callback, as it does for clarify.

* feat(connectors): register a connected MCP server and report its tools in the result

After a successful install or authorization the target carried the probe's tool
names and the model was told the tools "become available on your next turn". MCP
tool schemas are deferrable by construction, so nothing about them lives in the
sent tool array; a server registered in the scoped registry is callable through
tool_describe/tool_call in the same turn. The operation now registers the server
(register_mcp_servers under the owner's home scope) once authorization is
committed, records the registered names on the target, and the settled result
carries a tools_listing block in the deferred-catalog format plus a note that the
tools are callable now. A registration failure keeps the target connected with
tools: [] and a sanitized discovery_error. agent.tools and the system prompt are
untouched; the between-turns refresh updates the catalog block as before.

The card gate no longer asks for the desktop platform. Every surface that renders
the card attaches a connection callback (Desktop, the Ink TUI, the classic CLI);
registry dispatch and messaging sessions attach none and keep the link result.

Pre-commit rollback in probe_with_rollback used restore(only_if_absent=True),
which skips the rollback when a token file exists. On a first-ever authorization
the only file is the one this attempt wrote, so a token the resource rejected was
kept. Live E2E (controlled provider answering 403 to the issued token) showed the
row fail and the token survive; the rollback now restores the snapshot outright,
and the same run shows the token file removed.

* fix(connectors): install an OAuth catalog entry through the card's own flow

The card's install ran install_entry and then a plain probe. For an OAuth entry
that probe has no card flow around it: in the desktop backend it failed at once
("non-interactive environment and no cached tokens"), and in the classic CLI it
saw a TTY, opened a browser by itself and drew install_entry's curses tool
checklist over the panel. Since a probe failure is now an error, the failed
install was rolled back with _remove_mcp_server, and authorize refuses a server
that is not configured. A clean home had no path to a connected OAuth entry, which
is 55 of the 65 catalog entries. Found by the live three-surface run.

An install now builds the entry's configuration in memory (card_install_config:
no prompts, no probe, no checklist; a prior tool selection or the manifest's
curated filter applies). An OAuth entry starts the same flow authorize uses with
that configuration and the setup values in the attempt's secret scope, so the row
reaches the URL step, and the configuration and the setup values are saved
together when initialize accepts the token. Every other entry is probed in memory
and saved after the server answers. A failure writes nothing, so a failed
reinstall keeps the previous configuration, and the failed row asks for its fields
again so the card can reopen the form over the draft it kept.

* fix(agent): make a server connected in this turn callable in this turn

tool_describe and tool_call resolve names inside the agent's toolset selection,
which is fixed when the agent is built. A server that manage_connections had just
registered was therefore "not found" for the rest of the turn whose result calls
its tools available, and stayed out of the next turn's catalog too. The live
Desktop run showed it: the result listed mcp__fx_oauth_fields__echo and the
tool_describe that followed answered not_found.

The executor now adds the MCP servers the call connected to the selection. Only
the selection changes; agent.tools does not, so the sent tool schema bytes stay
the same. A selection of None (every toolset) and the no_mcp sentinel are left
alone.

* fix(cli): reopen the connection form when a required field is still empty

When the backend refuses an answer because a required field is missing it keeps
the row pending and names the fields. The panel mapped that frame to its waiting
phase, which draws the detail line and nothing else, so the user saw "waiting for
FX_API_KEY" with no fields and no buttons until the 300 s deadline. The panel now
returns to the form on the first missing field, over the draft it kept.

* test(connectors): the no-card path is the one with no callback attached

The card gate is "a connection callback is attached" since the classic CLI got
its own panel. This test still attached one under platform "cli" and expected no
card, so it opened a real operation, waited out the 300 s deadline and failed.
It now drives the path that has no card: no callback.

* fix(connectors): order a cancel against the commit and stop deleting a working grant

Found by the live runs on Desktop, the Ink TUI and the classic CLI.

A user's skip did not stop the OAuth attempt. With the worker parked in the token
request, the row settled "skipped" and the token was written 33 s later. A skip
now cancels the attempt, and one lock orders that cancel against the commit: the
attempt is either canceled with the earlier tokens restored, or committed and
kept. When the commit won, the skipped row says the authorization was kept. An
interrupted turn cancels its attempts the same way.

Every attempt began by deleting the saved tokens, so retrying discovery for an
authorized server demanded consent again, and a cancel in between left no grant
at all. The card's flow now connects with the saved tokens first, with no browser
step; only when they do not work does it replace them. The RPC session surface
keeps the old behavior because its caller waits for an authorization URL.

A second Connect from the form a failed row reopened was dropped without a frame,
which left the Desktop dialog with Connect loading and Cancel disabled until the
deadline. An approval on a failed or expired row is now a retry with the new
values.

The reported tool names came from the registration call, which returns nothing
for a server the process already holds. A retry after a failed listing therefore
said "no tools" while the server had them. The names are read from the registry,
and a parked server is woken first.

An authorization that commits after its card closed by deadline was never
registered, so the next turn still could not reach it. The runner keeps such
attempts, and the between-turns refresh adopts the ones that were approved.

An error with no message reached the user as a class name ("CancelledError").
The tool description still said a server's tools arrive on the next turn.

* fix(desktop): let an OAuth install open its link, and keep the form's draft

An install of an OAuth catalog entry with no setup fields reached the URL step
and gave the user nothing to click: an initiated install was always drawn as a
disabled spinner, and the only other place the link is shown is the setup dialog,
which opens for entries with fields. That is most of the catalog. An initiated row
that carries a link now offers Open, whatever the action.

The setup dialog reset its draft whenever the field list changed identity. The
backend sends a fresh list with every frame and an empty one while an attempt
runs, so a failed Connect erased what the user had typed. Fields now only fill in
what the draft lacks, and closing the dialog drops the draft.

The settled summary dropped the "tools unavailable" fact, and the live row offered
a Try again for that state which the gateway refuses for a connected target. The
summary keeps the fact and the row offers no dead control.

* fix(tui): keep the typed draft when a Connect fails

The overlay reset its draft whenever required_env changed identity, and every
backend snapshot delivers a freshly parsed array. A failed Connect therefore came
back as a form with the default region and an empty secret. The draft now resets
per target only, and a snapshot's fields fill in what the draft lacks.

* fix(cli): show the URL step and start an install that has no fields

The panel applied the user's answer and then set its phase to "waiting". The
backend applies the answer on the same thread and its change hook had already set
the next phase, so the URL step of an OAuth install and the reopened form for a
missing field were both overwritten, and the card sat on "Waiting…" until the
deadline. The waiting phase is now set before the answer is applied.

A pending install or enable with no fields opened in the waiting phase, which
sends no approval, so the flow never started. It now opens on Connect/Cancel. A
target that already carries its link opens on the URL step.

Connect on a failed row re-ran the attempt without the values now in the draft; it
sends them. The authorized-without-tools phase offered a "Retry discovery" that a
connected target cannot run inside the same operation; it offers Continue.

* fix(connectors): a newer OAuth attempt replaces the older one for the same server

A card that closed by deadline leaves its worker waiting on the browser for up to
300 s, and a tampered callback leaves one waiting too. A retry or a new operation
for the same server then ran beside it: both wrote the same token files, and the
older one's rollback could write over the newer attempt's grant.

The newest attempt per home and server is recorded. Starting one cancels the older
attempt, takes over its pre-attempt snapshot so a later failure still restores the
state from before either, and the older attempt's rollback leaves the files alone.

* fix(desktop): label an install's link control "Open in browser"

The control that hands an install's authorization link to the browser reused the
action's verb, so the row showed "Install" before the click and "Install" again at
the link step, told apart only by the cue. It now reads "Open in browser", the
label the setup dialog already uses for the same act. Authorize keeps its verb.

* docs(mcp): describe the setup card on the desktop, the terminal UI and the CLI

The MCP guide said the chat install exists only in the desktop app and that the
CLI relays commands. All three surfaces now show the same card: fields, Connect or
Cancel, an authorization link the user opens, one save when the server has
accepted the token, and tools the agent can call in the same turn. The tools
reference gains the result fields (tools, tools_listing, discovery_error) and the
no-card behavior of an OAuth install.

* fix(cli): keep the layout hook callable without a connection widget

The CLI panel commit added connection_widget to _build_tui_layout_children as a
required keyword. That method is the documented override point for wrappers, and
five existing tests (extension hooks, prompt stash, subagent dock) call it without
the new argument, so CI failed with a TypeError. The argument is now optional, like
the other widgets added after the hook was published; a missing widget is left out
of the layout.

The settled tool result also carried the target's setup instructions. Those are
the card's text for the user, and a catalog entry's notes can predate this flow
("restart your session so the tools are loaded"), which contradicts a result that
says the tools are callable now. The model-facing result drops them; the card
payloads keep them. This restores test_connector_local_batches.

* fix(connectors): wait for an in-progress registration before reporting a server's tools

Found with the real Vercel MCP server. Saving the configuration wakes the config
watcher, which starts its own connect for the new server. The operation's
registration call then skips the server as "already connecting" and returns at
once, so the card settled "connected" with no tools, and the 214 tools were
registered three seconds later. With no names in the result the model searched,
found the hosted connector of the same vendor and asked the user to connect that
instead.

The registered names are now read once the registration has finished: while
another task is connecting the server the read waits (30 s at most), a parked
server is woken once, and a server that finished registering with no tools is
still a valid empty list.

fef0bc56b2 refactor(cli): one notification payload, one sink per branch in _ring_bell
Review fold: build "\a" + sequence once and dispatch it to exactly one sink (app loop
when the Application runs, write_tty otherwise) instead of two branches with two writes
and two try/excepts. terminal_notify.notify() had a single caller (that fallback), so
write_tty is the public no-app entry and notify() is gone. The loop-side write keeps the
never-raises contract on a dead tty (EIO/closed file) the same way _pet_flush_kitty_frame
does, and _ring_bell skips entirely once _terminal_io_broken is set.

pty A/B re-run on this stack: 400 rings vs 90 frames, 0 aborted, 0 painted, 400/400 delivered.

ac2359cd35 fix(cli): turn-end notifications no longer paint the pet's kitty frame as base64
Symptom (Ghostty, display.pet on, display.bell_on_complete on): at the end of a turn the
input line fills with several rows of base64 and a stale copy of the status bar + pet
stays above the response panel.

Root cause: _ring_bell runs on the agent thread and terminal_notify wrote the OSC 9 /
OSC 777 sequence through its own open("/dev/tty") (or sys.stdout). The prompt_toolkit
loop thread may at that moment be mid-write of a 12 KB kitty APC pet frame, which the tty
drains ~1 KB at a time. The second writer splices into the frame; the foreign ESC aborts
the APC and the terminal paints the remainder of the payload as text at the input cursor.
The wrapped garbage scrolls the screen, so the panel that follows is printed against a
stale cursor position and the old chrome survives above it.

Change: when the CLI's Application is running, _ring_bell hands "\a" + the notification
sequence to the app loop (_run_on_app_loop -> _write_terminal_sequence), serializing it
behind the renderer and the after_render frame writer. terminal_notify.notify() keeps the
/dev/tty path for callers without a running app; the sequence builder is split out as
notification_sequence().

Verification: pty A/B with the real Application + after_render frame writer, 400 rings
vs 91 frames — base: 3 leaks (4,324 base64 chars painted); fixed: 0 leaks, 400/400
notifications delivered, 0 aborted frames.

3e066dfedd fix(computer_use): approval goes through the shared gate; no callback now fails closed
computer_use kept its own approval decision: two module dicts
(_session_auto_approve / _always_allow) mirroring tools.approval's
session store and _persist_choice, a private verdict vocabulary
(approve_once/approve_session/always_approve) that hermes_cli mapped
back to once/session/always, and — the real problem — `if
_approval_callback is None: return None`. Only the interactive CLI ever
installed that callback, so every other host (gateway turns, cron,
api_server, tui_gateway, ACP) ran destructive desktop input with no
approval at all, ignoring cron_mode / unattended_mode / the permanent
allowlist, and "always" grants were invisible to `is_approved`,
`clear_session` and the messaging-platform approval buttons.

_request_approval now calls tools.approval._run_approval_gate with
pattern_key `cua:<action>:<background|foreground>` (the old scope shape,
so a background grant still never covers the visible foreground variant)
and fail_closed_when_no_human=True, the same posture as
request_tool_approval / the SSH-config write gate. The private dicts,
their release/atexit clearing, the verdict mapping in
hermes_cli/cli_modal_mixin.py and the extra callback install in cli.py
are deleted: the CLI's terminal_tool callback answers computer_use
prompts like any other tool. set_approval_callback stays as an optional
explicit-callback hook with the shared callback contract
(cb(command, description, **kw) -> once|session|always|deny|timeout);
no in-tree host uses it.

Behavior change:
- No approval callback and no gateway (cron, api_server/webhook,
  headless -q, plain library use): destructive actions are now REFUSED
  with a BLOCKED error and never reach the backend. Previously they
  silently ran. cron honors approvals.cron_mode, unattended platforms
  approvals.unattended_mode, -q approvals.single_query_mode.
- --yolo / gateway /yolo / approvals.mode: off still allow (unchanged).
- Gateway sessions (Telegram/Discord/Slack/...) now get a real pending
  approval with once/session/always buttons instead of default-allow.
- session/always grants live in tools.approval's store; "always" is one
  command_allowlist entry (`cua:click:background`) and is scoped to that
  action+mode — the old blanket "always_approve unlocks everything for
  the session" no longer exists.
- Denial wording is the shared gate's ("BLOCKED: User denied ...",
  "BLOCKED: Action timed out ..."); the error JSON keeps `action`.

Tests: tests/tools/test_computer_use_approval_isolation.py
::test_no_callback_refuses_unless_yolo (blocked + no backend call, then
yolo executes) and ::test_always_grant_lands_in_the_shared_store
(is_approved sees the cua:<action>:<mode> key; second call served from
the store). Sabotage: restoring the `callback is None -> allow`
short-circuit fails the first; swapping the shared gate for a private
grant set fails the second plus the three delivery-ladder scope tests.
tests/tools/conftest.py gains `grant_computer_use_approvals` for
dispatch tests that only care about routing.

d9ca9c974d feat(vault): two-factor codes — automatic from a saved authenticator key, otherwise asked for in the user's UI
Follow-up to #106480. Sites that ask for a code after the password stopped
the agent cold: the login classifier excludes one-time-code fields on
purpose (a password must never land in an OTP box) and there was no tool
for the second step, so the only move was to ask in chat.

browser_vault_enter_code
  Fills the one-time code the current page asks for. Two sources, same
  invariant as passwords (the code goes to the page over the supervisor
  socket and never enters model context):
  - a TOTP seed on the login: local vault `otp_secret` (RFC 6238, stdlib,
    verified against the RFC test vectors), 1Password `op item get --otp`,
    Bitwarden `bw get totp`. Nobody is asked.
  - no seed: the surface prompts "Verification code for {site}"; the user
    types what their phone/email/app shows. Enter on empty / Skip declines
    and the tool returns code_declined ("do not ask again this turn").
  no_code_field tells the model the site wants a passkey / hardware key /
  app approval: hand it to the user's device and wait for navigation.
  Per-digit OTP boxes (maxlength=1 pattern) get one digit each in DOM order.

Surfaces
  CLI: sudo-style panel, code shown as typed (not a secret worth masking,
  typos must be visible), Enter submits, ESC/empty skips.
  Desktop: "Verification code for {site}" card via vault.code.request /
  vault.code.respond (gateway), owner-routed like the other vault prompts.
  Settings → Passwords & Logins: optional "Authenticator key" field on the
  add form (base32 or otpauth:// link); items with one show a "2FA auto"
  badge. `hermes vault add` asks for the same optional key.
  browser_vault_fill's result now says what to do next ("if the site asks
  for a verification code, call browser_vault_enter_code with this handle").
  Six locales.

Verified live (real model, local 2FA site that checks the TOTP; CLI PTY):
  A. login saved with authenticator key → signed in through 2FA, zero
     prompts, code/password absent from the transcript
  B. login without key → code panel → user types code → signed in
  C. panel dismissed → agent stops and explains, never asks in chat
Unit: RFC 6238 vectors, seed normalisation, mint-without-asking, per-digit
spread, decline, no-code-field; Desktop card test (owner routing, trim, Skip).

98d11c95f4 feat(vault): zero-setup UX — save a login on the page that needs it, managers auto-detected, one "Passwords & Logins" surface
Nobody should have to learn `hermes vault add` or find a toggle before "log into GitHub" works.

- browser_vault_save_login: when the agent reaches a sign-in page with no saved login it asks the user
  on THEIR surface (CLI two-step panel on the sudo modal: identifier shown, password masked; Desktop
  card with labelled Email/username + Password fields). The answer goes to the encrypted vault bound to
  the page origin and is filled at once; the model gets back only the handle and identifier. Declining
  returns save_declined; headless sessions get prompt_unavailable. Never a password in chat.
- Vault tools ride with the browser toolset (check_browser_requirements) instead of appearing only once
  the vault has items — an empty vault is exactly when save_login is needed. browser_vault_list hints
  at it when empty.
- 1Password / Bitwarden are login sources as soon as their CLI is installed; `vault.<name>.enabled`
  is opt-OUT only. Settings shows Detected/Locked/Unlocked/Off/Not detected with a switch only for
  installed managers; `hermes vault sources` reports detection, `--disable`/`--enable` flip the opt-out.
- Desktop nav/page renamed "Passwords & Logins"; empty state tells the user they do not need to add
  anything; all five locales updated. Docs rewritten from "how it works" to "say log into X".
- New per-thread SaveLoginPrompt callback (agent/vault_backends/unlock.py) installed beside the unlock
  prompt on every CLI site and the gateway bridge (vault.save_login.request/respond/expire), propagated
  to worker threads via tools.thread_context.

Live: CLI PTY (real model, packaged Chromium, local login server) — panel shown, identifier + masked
password typed, server received the correct password, password absent from terminal transcript and
from every file under HERMES_HOME outside vault/. Native Electron (headless, isolated HOME/HERMES_HOME,
own Vite + CDP port) — card shown, "Save & sign in", server received the password, Settings lists the
saved item, password absent from the rendered UI.

8e7e9be217 feat(vault): sign in with 1Password or Bitwarden logins, unlocked per session
The browser vault now draws from three login sources behind one handle
shape: the local encrypted vault (vault_…), 1Password Login items (op:…)
and Bitwarden Password Manager logins (bw:…). browser_vault_list aggregates
metadata across them; browser_vault_fill routes by prefix and resolves the
password at fill time only, through the manager CLI.

External managers are locked until the user unlocks them for the current
session. The new browser_vault_unlock tool (and the fill path, implicitly)
asks the surface to show a masked master-password prompt — CLI panel
(reuses the sudo panel state), TUI/Desktop via a vault.unlock.request
blocking card. The password goes to `op signin --raw` / `bw unlock --raw`
on stdin, never argv or env; only the session token is kept, in memory,
with a 30-minute idle TTL, cleared on session close or `vault.lock`.

Headless contexts (cron, webhook, api_server, -q) can never prompt: the
manager is reported as locked with unlock=unavailable_in_this_session and
fill refuses — the same posture approvals take where nobody can answer.

Config: vault.onepassword / vault.bitwarden {enabled, binary_path, …};
a 1Password service-account token skips the prompt for headless use.
RPC: vault.sources, vault.source.set, vault.unlock, vault.lock for Settings.

Tests (2, real subprocess against a fake bw; each proven red by sabotage):
headless never prompts or spawns; unlock feeds stdin only, token never
enters os.environ, fill routes by prefix and the password only reaches the
fill script.

For each issue anchor present in BASE 63279301bc non-test .py and absent on HEAD, the BASE comment/docstring block was re-attached at the HEAD location of the code it explained (matched by the distinctive code line / enclosing def). Sentences already covered by an existing HEAD comment were deduped; the issue number always survives. Insert-only: no code lines changed.

eb74a00c71 refactor(cli): split HermesCLI into 10 cohesive mixins (cli.py 22,284 -> 9,150)
326 methods lifted by AST (bodies identical; ast.dump-verified) into
hermes_cli/cli_{tui,status_bar,voice,model_switch,session,stream,modal,
terminal,info,loops}_mixin.py. cli.py-internal symbols resolve via lazy
'from cli import ...' inside each method (no import cycle; patch('cli.X')
keeps working). The three 'global' writers (_skill_commands, _cli_wake_owner)
now write the cli module attribute explicitly so the origin's readers still
see them. Dropped imports left unused in cli.py; kept display_hermes_home /
build_welcome_banner as re-exports (mixins + tests resolve them via cli).
Repointed two AST change-detector tests to cli_tui_mixin.py; one test
fixture now keeps 'cli' in sys.modules across its patch.dict scope.
