Merge origin/main into feat/desktop-remote-ssh-current

Browse source 
Sync with main after the contribution-shell refactor (#60638) and the backendConnectionState extraction (#65885) landed. Seven conflicts, all resolved in favor of main's new architecture with the SSH lifecycle ported on top:

- electron/main.ts: adopt backendConnectionState (attempt tokens, attachProcess, clearPromiseForAttempt) as the sole owner of the primary backend; drop the branch's raw hermesProcess/connectionPromise globals and commitConnectionFailure call site. SSH liveness-streak classification, teardown, and the SSH quit path are layered onto the new ownership model; before-quit combines SSH transactional teardown with the Windows sandbox marker (#38216).
- desktop-controller.tsx: deleted on main; its SSH beforeConnectionSwitch cleanup (preserved-route fresh draft, overlay return-route reset, project-tree reset, close-all-terminals) moves to contrib/wiring.tsx's useGatewayBoot call.
- use-session-actions/index.ts: keep main's onFreshDraftRouteIntent (fires unconditionally); preserveRoute gates only the navigate.
- gateway-settings.tsx: keep main's acceptSavedConfig/connectedCloudUrl; every save/sign-in/sign-out success path routes through acceptSavedConfig with the branch's stale-async seq guards intact.
- boot-failure-reauth.ts: keep both sshFailureMessage and main's isRemoteReauthFailure formatting.
- Both test harnesses take the union of props.

Validation: tsc -b clean; desktop suite 1704 passed / 1 skipped; electron SSH/connection modules 225 passed; python SSH + web_server suites 508 passed.

# On push to main (or manual trigger), run `npm run fix` on each workspace

# Fixable lint issues (import sorting, unused imports, curly braces, etc.) are
# auto-corrected on merge so PRs aren't blocked by them. The PR-time eslint
# check in typecheck.yml fails only when un-fixable errors remain.
#
# NOTE: AUTOFIX_BOT_PAT pushes DO trigger further workflow runs (unlike
# secrets.GITHUB_TOKEN). The concurrency group (ts-autofix-${{ github.ref }})
# with cancel-in-progress: true prevents an infinite loop — a re-triggered
# run cancels the in-flight one, and since the second run finds no new fixes
# (the first run already applied them), it exits with an empty patch.
#
# ── Security model: two-job split ───────────────────────────────────────────
#
# The eslint process executes repo code (eslint.config.mjs, package.json
# scripts, installed plugins). To prevent a malicious PR from getting arbitrary
# code execution on a runner with push access, the work is split:
#
# 1. generate-patch (unprivileged, contents: read only)
# Checks out, installs deps, runs eslint --fix, produces a .patch artifact.
# Worst case: malicious code runs here on an ephemeral runner with zero
# push permissions.
#
# 2. apply-patch (privileged, contents: write + pull-requests: write)
# Checks out, downloads the patch artifact, applies it, pushes to the
# bot/js-autofix branch, creates/updates a PR, and enables auto-merge.
# This job never runs npm, never installs anything, never executes any
# repo code. The only input it trusts is the patch artifact.
# Skipped entirely when generate-patch reports no fixes (has-fixes != true).
# The PR auto-merges (squash) once CI passes. If CI fails or main moves,
# the PR is auto-closed and the branch deleted — the next run re-applies

### Subprocess-per-test-file isolation
**Flake policy:** the runner auto-retries a failing test FILE once in a fresh
subprocess (`--file-retries`, default 1; `HERMES_TEST_FILE_RETRIES=0` to
disable). Pass-on-retry counts as green but is printed in a `⚠ FLAKY` summary
section with both attempts' output. A FLAKY report is a bug to fix, not noise
to ignore — timing-sensitive tests must not assume a quiet runner (loose
wall-clock bounds ≥ 2s, event-based sync, no `assert not _wait_until(...)`
negative-timing races).
#### Subprocess-per-test-file isolation
Every test file runs in a freshly-spawned Python subprocess via `run_tests_parallel.py`. This means module-level dicts/sets and
ContextVars from one test file cannot leak into the next.

### Where to place what tests
The CI change classifier (`scripts/ci/classify_changes.py`) runs specific jobs based on what files changed. A Python test that asserts
about the contents of `package.json`, `package-lock.json`, `.ts`/`.tsx`
source, or any other JS-side artifact will not run on a PR that only touches
those files. This means a regression can go green on a PR and red on `main` (where the
classifier fails open and runs everything).
Any test that reads or asserts about `package.json`,
`package-lock.json`, `tsconfig.json`, `.ts`/`.tsx`/`.js`/`.mjs`/`.cjs`
source files configuration belongs in the JS (vitest) test suite, not in `tests/*.py`.

"""Ambient session-accounting context for auxiliary LLM calls.
Auxiliary calls (vision, compression, title generation, web_extract,
session_search, ...) funnel through ``agent.auxiliary_client`` which has no
session handle — so their token usage was historically discarded, leaving
dashboard analytics blind to aux model spend (issue #23270).
Instead of threading ``session_db``/``session_id`` parameters through every
aux call site, the agent loop publishes them here (mirroring the Nous Portal
conversation context in ``agent.portal_tags``) and the auxiliary client
records usage at its single response-validation chokepoint.
ContextVar semantics give us the right isolation for free:
* concurrent agents in one process (gateway sessions, delegate subagents)
never see each other's accounting context;
* worker threads spawned via ``tools.thread_context.propagate_context_to_thread``
(MoA fan-out, background review) inherit the parent turn's context;
* asyncio tasks inherit the context of the code that created them.
MoA reference/aggregator slots are explicitly EXCLUDED from recording:
``agent/conversation_loop.py`` already folds MoA advisor usage and cost into
the main loop's ``update_token_counts`` delta, so recording them here would
double-count (see ``_EXCLUDED_TASKS``).

"""Shared dollar-denominated usage model for the billing/subscription surfaces.
The single source of truth behind the ``/usage`` and ``/subscription`` usage
bars (TUI + CLI). User feedback (Jun 2026): the terminal surfaces show
**dollars**, never "credits", and every usage bar must make the monthly
subscription allowance and separately-purchased top-up dollars distinctly
visible.
Data source: the NAS account-info fetch (``NousPortalAccountInfo``), whose
``paid_service_access_info`` carries the three dollar magnitudes we render
(despite the legacy ``*_credits`` field names, these are USD floats):
- ``subscription_credits_remaining`` -> plan dollars left this month
- ``purchased_credits_remaining`` -> top-up dollars left (rolls over)
- ``total_usable_credits`` -> total spendable
plus ``subscription.monthly_credits`` (the plan's monthly $ allowance, the
denominator for the "% used" plan bar) and ``current_period_end`` (renewal).
Design: two SEPARATE bars (decided with the user) rather than one crammed
three-segment bar — at terminal widths three same-glyph density segments are
unreadable. The plan bar is "spent vs allowance this month" (carries % used);
the top-up bar is "money you bought, doesn't expire". Each gets full
resolution and a single fill glyph, so the bar is never ambiguous and never
relies on color.
Fail-open everywhere: any missing/non-finite field degrades to fewer bars or a
magnitudes-only view; a logged-out / unreachable portal yields
``available=False`` and the surface shows nothing.

start of a bare slug (``claude-opus-4``). Strip the region prefix
(``us.``/``eu.``/``apac.``/...) and try two candidate slugs against the
floor:
* the segment after the provider namespace (``claude-opus-4-6-v1:0``) —
matches Anthropic-style slugs whose floor key excludes the provider
(``claude-opus-4``); and
* the region-stripped id with the provider dot rewritten to a dash

(``deepseek-r1``).
The floor's right-anchor (``$`` or ``-``/``.``/``_``) tolerates the
trailing date-stamp / ``-v1:0`` version suffix, so no suffix stripping is
needed. First non-None wins; returns None for unknown models.
The floor table mixes version-separator conventions: some keys are
keyed with a dashed version (``claude-opus-4``) while others embed a
dotted version (``claude-sonnet-4.5``, ``claude-sonnet-4.6``). Bedrock
always dashes the version (``claude-sonnet-4-5-v1:0``), so for every
candidate slug we also try the alternate version-separator form —
digit-dash-digit rewritten to digit-dot-digit and vice-versa — so a
dashed Bedrock id matches a dotted floor key (and the reverse). The
rewrite only touches version-number separators (a dash/dot flanked by
digits), never other dashes in the slug, so ``claude-sonnet`` is left
intact while ``4-5`` becomes ``4.5``.

"""Best-effort accessors for the single-writer stream fence (#65991).
The fence itself lives on ``AIAgent`` (``_claim_stream_writer`` /
``_stream_writer_is_current`` in ``run_agent.py``), but the streaming code paths
that use it live in *other* modules — ``chat_completion_helpers`` (chat /
anthropic / bedrock) and ``codex_runtime`` (codex responses). Calling the fence
directly as ``agent._claim_stream_writer()`` from those modules makes them
hard-depend on the method being present on whatever object is passed in as
``agent``.
That coupling is a latent crash: a partially-updated checkout (the streaming
helper module newer than ``run_agent``), a hot-reloaded gateway, a duck-typed
agent, or a test double without the method turns an *additive* safety net into a
fatal ``AttributeError`` that aborts the whole turn. A cron job died exactly
this way with ``'AIAgent' object has no attribute '_claim_stream_writer'``.
The fence is only ever allowed to drop a *provably* superseded stream — never
the sole legitimate writer. So when the guard is unavailable (or raises), the
correct degradation is "no fence": keep streaming. These helpers make the

**Icon-only buttons must have a tooltip.** Every button with an `icon*` size
carries no visible text label, so it must be wrapped in `<Tip label={...}>`
with a descriptive label (matching the button's `aria-label`). Never use the
native HTML `title=` attribute — it's unstyled, delayed (~500ms OS default),
and visually inconsistent with the instant themed `Tip`. An enforcement test
(`src/components/ui/__tests__/no-native-title.test.ts`) fails on any `<button>`
or `<Button>` that still carries `title=`.
**Keybind hints in tooltips.** When a button corresponds to a rebindable
hotkey, use `<TipKeybindLabel actionId="..." />` as the `Tip` label — it
auto-reads both the i18n label and the current keybind combo from the store,
so the hint stays live when the user rebinds. Pass `text={...}` only when the
tooltip is context-dependent (e.g. "Show" / "Hide" based on state). Never
hardcode combos in components — always read from the `$bindings` store via
`useKeybindHint` or `TipKeybindLabel`.
