A TimeoutExpired from one hermes-gateway*.service used to abort the whole
per-scope restart loop, leaving later profile gateways on pre-update
in-memory code after hermes update. Catch timeouts per unit, continue the
fleet, warn with the exact stale units, and exit non-zero when any remain
unrestarted (#68523).
The fatal-error notification runs on the failing adapter's own polling
task, and adapter.disconnect() inside the handler can cancel that task
(its current-task guard misses because _safe_adapter_disconnect runs the
close in a wrapper task). The CancelledError killed the handler between
the fatal log and the reconnect queue, leaving the platform permanently
dead inside a live gateway process. #68447 fixed this for telegram at
the adapter layer; this hardens the shared gateway dispatch so every
platform gets the same protection (qqbot #25505/#29005, photon #68693).
- _handle_adapter_fatal_error now runs the real handler in a detached
task, awaited through asyncio.shield() so caller cancellation cannot
tunnel into it (Task.cancel() also cancels the task's _fut_waiter).
- If a retryable platform still ends up neither reconnected nor queued,
the gateway exits with failure so launchd/systemd KeepAlive restarts
it instead of running indefinitely with a dead platform (#68693).
Fixes#68693

The three behavior tests (control proves dup, boundary is noop, tail-only
write) fully cover the flush semantics. The source-grep test reading
cli.py + cli_commands_mixin.py as text and asserting a string appears is
a change-detector that breaks on benign refactors without adding coverage.
Closes#68454
Root cause: cold-resumed transcript rows lack _DB_PERSISTED_MARKER until a
normal turn flush stamps them. Immediate /new,/resume,/branch flushed with
no history boundary, so every restored row was re-appended to the old session.
Fix: pass conversation_history=self.conversation_history at all three sites
(mirrors #68205). Add offline regression coverage for noop + tail-only write.
Verification: pytest tests/agent/test_session_rotation_flush_cold_resume_68454.py (4 passed)
The KeyboardInterrupt handler in run_gateway() was the only exit path
that still used bare 'return' instead of _hard_exit_after_gateway_teardown().
While less common than service-managed restarts, a console Ctrl+C still
leaves the process vulnerable to the same Python finalization hang on
non-daemon worker threads (cron ThreadPoolExecutor jobs). Route it through
the same backstop, with a 'return' guard for test stubs that don't raise
on code 0 (production os._exit never returns).
* feat(desktop): native in-app downgrade (chargeless preview → schedule → undo)
Ticket 11, stacked on the Billing revamp (ticket 09). Downgrades no longer bounce
to the portal — picking a lower tier runs the gateway pending-change flow in-app;
the scheduled state renders on the plan card with an undo. Upgrades keep the portal
deep link.
- api.ts: add previewSubscriptionChange / scheduleSubscriptionChange /
resumeSubscription wrappers over subscription.preview|change|resume
({subscription_type_id} / {}), typed via SubscriptionPreviewResponse +
BillingMutationResponse (now re-exported from types.ts).
- use-subscription-change.ts (new): useDowngradeFlow (preview → confirm → schedule,
refetch + onScheduled on success; typed refusals surface via the shared
BillingRefusalInline, so insufficient_scope drives the existing step-up exactly
like the auto-reload save, retried in place) and useResumeFlow (confirm-less undo).
Both accept a `simulate` switch so DEV fixtures click through with canned success.
- plans-view.tsx: downgrade tiles are now an actionable "Downgrade" that opens an
in-card preview → confirm panel (mirrors the TUI confirm copy: "…takes effect
<date>. No charge now; you keep your current plan until then."). The scheduled
downgrade target renders an inert "Scheduled" marker; other lower tiers stay
actionable (picking one reschedules).
- CurrentPlanCard: when a downgrade is pending, the caption reads "Changes to
<tier> on <when>." with an inline Undo → resume → refetch. One line, no jumps.
- use-billing-state.ts: BillingPlanTierView gains a `scheduled` state (and drops the
ticket-09 disabled-downgrade caption); derivePlanTiers matches the pending target
by name (NAS sends no id for it) before the downgrade branch; BillingPlanCardView
gains `pending`, derived from current.pending_downgrade_* .
- inline-feedback.tsx (new): extracted openExternal / BillingRefusalInline /
StepUpInlineAction / InlineMessage so the plans view reuses the step-up-aware
refusal renderer without a circular import; openExternal now delegates to the
canonical @/lib/external-link opener.
- dev-fixtures.ts: add `pending-downgrade` (subscriber-personal on Plus with a Free
downgrade scheduled for Aug 15) for the plan-card pending state + grid marker.
Tests (+16 → 94 green in the billing suite): api wrappers (preview/change/resume +
insufficient_scope refusal); view derivation (pending plan-card state, scheduled
grid marker); confirm flow (preview shown, change called with the right tier_id,
refetch on success, schedule refusal → step-up affordance); undo flow; the
use-subscription-change hooks (preview-refusal retry, cancel, simulate path).
Updated the ticket-09 downgrade tests for the now-actionable tile. typecheck
(app/electron/e2e) + lint clean.
PR (later): base sid/desktop-billing-revamp; retarget to main after #68722 (09) merges.
* fix(desktop): format downgrade credits delta as signed dollars
The downgrade preview rendered the raw wire string ("Monthly credits change:
-88."), violating the "monthly credits are DOLLARS" ruling. NAS sends
monthly_credits_delta as a bare decimal; format it as signed dollars through the
same money formatter ("−$88/mo", sign preserved, abs value formatted). Zero /
absent still hides the line.
Adds formatMonthlyCreditsDelta (exported) + unit tests (negative/positive/zero/
absent) and asserts the rendered "Monthly credits change: −$88/mo." in the confirm
flow. Billing suite 99/99 green; typecheck + lint clean.
* fix(desktop): downgrade flow hardening — concurrency guard, a11y, DEV-gated sim
Addresses the adversarial review of the native-downgrade diff.
- Concurrency: useDowngradeFlow exposes `mutating` (true only while the schedule
RPC is in flight). While a change commits, every other Downgrade tile and the
Back button are disabled; the active panel's Confirm/Cancel already lock. The
plan-card Undo blocks on its own resume via `busy`. (The server also 409s
overlapping per-org mutations — this is UI honesty, not the only defense.)
- Accessibility: the confirm panel is role="status" aria-live="polite" and takes
focus on open (tabIndex=-1 container); closing it returns focus to the tile card,
so keyboard focus is never stranded and the async preview text is announced.
- DEV-gated simulation: the canned preview/change/resume seam is ignored unless
import.meta.env.DEV, so a production build never takes the simulated branch even
if a `simulate` prop leaks through.
- Comments: documented the deliberate manual-retry-after-step-up (no auto-replay,
matching auto-reload) and that name-matching the scheduled target is safe because
SubscriptionTypes.name is @unique in NAS.
Tests (+5 → 104 green in the billing suite): mutating exposed only during schedule;
simulate ignored outside DEV; other downgrade tiles + Back disabled mid-schedule;
Undo disabled mid-resume; confirm panel role + focus on open. typecheck
(app/electron/e2e) + lint clean.
* fix(desktop): scheduled cancellations, downgrade-flow concurrency, inline nits
Addresses the native-downgrade review threads.
Scheduled cancellations were invisible (NEW review item). subscription.current
carries cancel_at_period_end + cancellation_effective_* and subscription.resume
clears cancellations exactly like downgrades, but the pending-transition helper only
read pending_downgrade_*, so a portal/TUI-scheduled cancellation rendered as a plain
renewal with no Undo. The pending state is now a union — { kind:'downgrade', tierName,
when } | { kind:'cancellation', when } — computed once in deriveBillingView and
threaded to BOTH the plan card and the grid. The card reads "Cancels on <date>." with
the same Undo (resume); the grid shows a Scheduled marker only for downgrades (a
cancellation has no target tier). Precedence: a downgrade wins if both fields are set
(it names a concrete target — the stronger signal), commented at the helper. Adds a
`pending-cancellation` fixture + tests (card copy, undo wiring, no grid marker,
downgrade-wins precedence).
Concurrency: confirm() takes a synchronous scheduling ref (mirroring useResumeFlow)
so two same-tick clicks — before React commits busy='schedule' — cannot fire two
schedule RPCs; the ref clears on every exit (simulated/stale/refusal/success).
useResumeFlow reorders its unlock: a refusal releases immediately, a success holds
runningRef/busy THROUGH the refetch so Undo never re-enables against the still-pending
card. Test: a synchronous double-activation fires one schedule RPC.
Inline nits: re-narrow link/action inside the click callbacks (`plan.link && …`,
`tier.action && …`) instead of relying on outer narrowing / `?? ''`.
Billing suite green (109); typecheck (app/electron/e2e) + lint clean.
* refactor(desktop): move DEV billing simulation behind the api seam
The fixture simulation lived as `simulate` / `simulateResume` prop drills and
`if (simulated)` branches inside the flow hooks, and it could not actually produce
the state it advertised (a simulated schedule never showed the pending card).
Replaced with `createSimulatedBillingApi(fixture)` — a fully in-memory BillingApi
built once, DEV-gated, in BillingSettingsWithDevFixtures where the fixture is known,
and supplied to the whole subtree via a new `BillingApiProvider` (context override on
`useBillingApi`; `null` = the real gateway api). It serves fetches from a mutable copy
of the fixture and its subscription-change mutations WRITE that copy's pending state:
schedule sets a pending downgrade, resume clears a pending downgrade OR cancellation.
Fixture mode now flows through the SAME react-query path (fetch short-circuit deleted;
queries always enabled; an effect refetches on fixture switch), so the click-through
genuinely progresses — schedule → pending card + Undo + Scheduled marker, undo → cleared.
Deleted `SubscriptionSimulation`, `simulationEnabled`, both prop drills, and every
`if (simulated)` branch — the hooks are now production-pure. Added a test driving the
full simulated loop (schedule → pending appears → resume → cleared), plus cancellation
undo and no-shared-mutation coverage. Removed the now-obsolete simulate hook tests.
Billing suite green (110); typecheck (app/electron/e2e) + lint clean.
* refactor(desktop): extract billing row/card components out of index.tsx
Purely mechanical, no behavior change: split the settings billing route file
(1065 → 593 lines) into focused siblings now that the downgrade feature has settled
their final shape.
- billing-amounts.ts — the dollar parse/format/validate/clamp helpers.
- account-row-value.tsx — RowValue (shared by AccountRow + AutoReloadRow).
- current-plan-card.tsx — CurrentPlanCard.
- auto-reload-row.tsx — AutoReloadRow (the in-place auto-refill editor).
index.tsx keeps the page shell, AccountRow dispatch, BuyCredits flow, and the fixture
wiring. Billing suite green (110); typecheck (app/electron/e2e) + lint clean.
* refactor(desktop): tighten the downgrade flow — phase union, previewMessage, tidy shared modules
Polish that composes with the api-seam rework:
- ActiveDowngrade's four nullables become a `DowngradePhase` discriminated union
(previewing | previewFailed | ready | scheduling | scheduleFailed). Impossible
combinations (a preview AND a refusal, "ready" with no quote) can no longer be
represented; the hook and panel branch on one `kind`, and `mutating` is simply
`phase.kind === 'scheduling'`.
- The five-way ternary in DowngradeConfirm is replaced by a pure `previewMessage(phase,
fallbackTierName)` helper; the misnamed `caption` className local is renamed `captionCn`.
- inline-feedback.tsx now holds ONLY the shared refusal/step-up pieces: `openExternal`
moves to its own `open-external.ts` (a thin wrapper over `@/lib/external-link`'s
`openExternalLink`), and `InlineMessage` moves back into its sole consumer
(auto-reload-row.tsx).
No behavior change. Billing suite green (110); typecheck (app/electron/e2e) + lint clean.
* feat(cli): plan catalog on Free + plan= deep link + top-up/auto-refill copy split
Bring the plain (non-TUI) CLI billing surface to parity with the desktop/TUI
billing changes:
- /subscription on Free (admin/owner, interactive) prints the plan catalog
(name · $/mo · $credits/mo, from the same tiers[] data the TUI uses; monthly
credits render as dollars). A numbered pick opens the manage-subscription
deep-link directly with plan=<tier_id> appended.
- subscription_manage_url(state, tier_id=...) appends plan=<tier_id> (the stable
tiers[] id) when a tier was picked, org_id first — mirrors the TUI's ?plan=.
The paid change flow's blocked/unknown-preview portal fallback carries plan=
for upgrades only; downgrades stay generic/native.
- /topup overview splits one-time top-up from automatic refill, the distinction
stated in each first sentence ("Add funds now — a single charge…" vs "Refill
when low — charges … automatically …"), keeping "credits" out of the
dollars-only surface.
- Downgrades remain native (chargeless scheduled change), unchanged.
Updates the CLI-parity section of docs/billing-lifecycle.md and tests under
tests/hermes_cli + tests/agent.
* refactor(billing): share plan-catalog helpers + harden manage-url builder
- subscription_manage_url now preserves unrelated portal query params (parse_qsl,
popping only the contract-owned org_id/plan) and restricts to http/https schemes,
matching the desktop URL builder — the function owns the contract.
- Lift the plan-catalog derivation into agent/subscription_view.py so the CLI Free
catalog and the paid picker/blocked-preview branch share one implementation:
selectable_tiers (enabled paid, not current, sorted), format_tier_row (name · $/mo
· $credits/mo — thousands-grouped like the TUI's toLocaleString, credits suffix
hidden when absent/zero), and is_upgrade(state, tier_id).
* fix(cli): numbered pick, canonical guarded browser opener, partial auto-refill copy
- Free catalog: accept a bare digit as a pick (the shared normalizer only knows the
confirm-dialog digit aliases, so `1` used to resolve to None → "Cancelled"). The
Nth digit maps to the Nth printed row.
- Extract one _open_url_in_browser used by every "open the portal" path, applying the
device-code flows' console-browser / remote-session guard (webbrowser.open returns
True even for lynx/w3m over SSH) and returning whether a real browser opened.
- Consume the shared selectable_tiers / format_tier_row / is_upgrade helpers from the
Free catalog, the paid picker, and the blocked-preview branch.
- /topup auto-refill copy: the concrete "charges $X … below $Y." sentence only when
both amounts are present and finite; otherwise the generic sentence.
* docs(billing): correct CLI-parity rows (drop cross-repo ref, downgrade invariant)
Remove the other-repo PR reference from the manage-URL row, and state the real
downgrade invariant: a blocked downgrade may print the generic manage URL but never
carries plan=<tier_id> — selected-tier deep-links are reserved for new subscriptions
and upgrades.
* feat(desktop): revamp Billing page — plan card, in-app plans view, tier art
Reshape the desktop Billing settings per wayfinder ticket 09. New page order:
Plan → Payment → One-time top-up → Automatic refill → Usage, with the at-a-glance
summary strip unchanged at the top.
- CurrentPlanCard replaces the old Subscription row: tier name + price + renewal
and at most one button — "View plans" (free/no-sub + can_change_plan),
"Change plan" (subscriber + can_change_plan), or none for teams / non-changers.
Teams keep the portal "Adjust plan ↗" link so they are not stranded. The button
navigates in-app to the plans sub-view.
- bview=plans sub-view mirrors the settings pview/kview pattern (useRouteEnumParam,
default overview). BillingPlansView renders a grid of PlanCard from live tiers[]
(is_enabled, sorted by tier_order, free tier included).
- PlanCard: tier art + name + $/mo + monthly credits as dollars ("$110 credits/mo").
Current tier is highlighted + inert; higher/no-current tiers get "Choose ↗"
(opens portal with plan=<tierId>); lower tiers are a DISABLED "Downgrade" with a
caption — downgrades move in-app in ticket 11 (gateway pending-change flow), so
this PR intentionally links them out/disabled rather than wiring the money path.
- buildManageSubscriptionUrl gains an optional third arg (tierId) → appends
plan=<tierId>. Signature kept identical to draft PR #68666 for a trivial rebase;
NAS #748 validates the param server-side.
- Tier art: four NAS hero webps rendered as ~40px thumbnails over a Nous-blue well
with per-tier blend modes (the only place Nous blue appears). Keyed by lowercase
tier NAME (free/starter→connect, plus→memory, super→automation, ultra→sandbox);
unknown name → text-only card. Imported via vite static imports for packaged
file:// + webSecurity.
- Top-up vs auto-refill disambiguated by section label + first sentence: "One-time
top-up" / "Buy credits now" vs "Automatic refill" / "Refill when low" (configured
copy reads "Charges $X automatically when your balance falls below $Y.").
- Variant-A auto-refill editing: Manage swaps the row's left side (caption → the two
$ fields with a pre-allocated error line) and the action column (Manage → Save/
Cancel) in place, with the row height reserved for the tallest state so the Usage
section never shifts. Fixes the spurious on-open validation error (errors now show
only after an edit or a save attempt). Save/disable API calls + confirm-disable
flow unchanged.
- Remove subscriptionTierChips and the subscription-row chips; reshape (not delete)
deriveBillingView to expose plan + tiers. Buy-credits row keeps the chips seam.
- Dev fixtures: add free-personal and subscriber-personal (personal orgs, full
4-tier Free/Plus/Super/Ultra catalog) so the plans view is exercisable.
Tests: update/extend index.test.tsx + use-billing-state.test.ts, add tier-art.test.ts;
delete the old chips tests. Desktop billing suite 70/70 green, typecheck clean.
* fix(desktop): mark the free/lowest tier current (not an upgrade) when there is no subscription
Visual verification caught a spec-fidelity bug: in the plans grid, an account with
no active subscription rendered the Free tier ($0/mo, tier_order 0) as a "Choose ↗"
upgrade — clicking would deep-link the portal to "subscribe to Free".
Ruling: current-card = tier.is_current OR (subscription.current == null AND the tier
is the lowest-order / $0 tier). derivePlanTiers now falls back to the lowest-order
tier as the stand-in current plan when there is no subscription, so the free card
renders exactly like is_current (inert, "Current plan") and — being the lowest order
— no tier can be a downgrade; every paid tier is a "Choose ↗" upgrade.
CurrentPlanCard is unaffected (still "Free" + "View plans"); subscriber-personal is
unchanged (Free stays a disabled Downgrade below the current Plus tier).
Tests: free-personal grid now asserts Free = current/inert, no downgrade state, three
Choose buttons; text-only unknown-tier test gains a free tier so the unknown paid tier
is unambiguously an upgrade. Billing suite 70/70 green, typecheck + lint clean.
* chore(desktop): shrink bundled tier art to 128px thumbnails
The plan-card wells render the art at ~40px; shipping the full landing
images added 2.7 MB to the repo for no visible difference. 128px covers
2x displays; total is now 26 KB.
* fix(desktop): address 6 adversarial-review findings on the Billing revamp
1. Grandfathered current tier (BLOCKER). NAS marks a grandfathered current tier
is_enabled:false; the enabled-only filter dropped it, leaving currentOrder
undefined so every lower tier rendered as an actionable "Choose ↗". derivePlanTiers
now resolves current identity/ordering against the UNFILTERED tiers and keeps the
grandfathered current tier in the grid as the inert "Current plan" card; downgrades
classify against its tier_order. (Non-current disabled tiers are still dropped.)
2. Dead plan-card button. derivePlanCard offered "View plans"/"Change plan" purely on
can_change_plan, but the grid could be empty / current-only and showPlans refused,
so the button no-oped. It now offers the in-app action ONLY when the grid has ≥1
actionable (non-current) tier; otherwise it falls back to the portal link.
3. Deep-link bypass. showPlans now gates on the same capability that renders the button
(view.plan?.action), so a team / non-changer deep-linking bview=plans always falls
back to overview instead of a grid of live Choose buttons.
4. Lost portal escape hatch. Whenever the card has no in-app action (teams, non-changers,
refused subscription, empty catalog) it now ALWAYS carries the "Adjust plan ↗" portal
link built from subscription?.portal_url ?? billing.portal_url — the refusal caption
no longer promises a portal the UI didn't render.
5. Choose URLs dropping org_id/plan. (a) derivePlanTiers now threads billing.portal_url
as the fallback base for the Choose URL. (b) buildManageSubscriptionUrl treats the
hard-coded FALLBACK_PORTAL_BILLING_URL as a last-resort ORIGIN (applying org_id/plan)
instead of a bare return, so a null portal_url never strips the routing params.
6. Zero-shift on narrow panes. Replaced the magic min-h-28 (under-reserved once the two
inputs stack below @2xl) with exact reservation: the edit form is always rendered and
both states share one grid cell ([grid-template-areas:'stack']), invisible+aria-hidden
when not editing — the row equals the tallest state at every width, no breakpoint math.
The refusal stays inside the reserved layer.
Tests: +12 (grandfathered current, no-dead-button + empty-catalog portal link, team &
personal deep-link fallback to overview, billing.portal_url-backed Choose URL, fallback
org_id/plan, reserved-form-mounted); updated the two portal-link expectations for §4.
Billing suite 78/78 green; typecheck (app/electron/e2e) + lint clean.
* refactor(desktop): reuse the shared openExternalLink helper in the plans view
* fix(desktop): honor the auto_reload wire contract — null card + disable amounts
A full-stack contract sweep (desktop ↔ shared types ↔ gateway ↔ NAS) surfaced two
real desktop bugs in the auto-refill row:
A. auto_reload.card can be null. The gateway's _parse_auto_reload_card returns None
for a missing/unknown-kind card and _serialize_billing_state emits `card: null`,
but the shared BillingAutoReload.card union had no null arm and use-billing-state
dereferenced `autoReload.card.kind` bare — a crash on the enabled path. Add `| null`
to the shared union (contract honesty) and guard the read (`card?.kind`); null now
falls through to the default enabled path, same as a canonical card.
B. Disable was rejected by the gateway. billing.auto_reload unconditionally requires
threshold + top_up_amount, so `updateAutoReload({ enabled: false })` came back
invalid_request. (The TUI always sends both; desktop fixture mode stubbed it.)
disable() now sends the current threshold_usd/reload_to_usd from the autoReload
prop alongside enabled: false, matching the TUI.
Tests: enabled auto_reload with card:null renders the normal enabled row (derivation
+ render, no crash); disable call carries both current amounts. Billing suite 80/80
green; typecheck (app/electron/e2e) + lint clean.
* fix(tui): guard the nullable auto_reload card in the auto-reload screen
The shared BillingAutoReload.card union gained its honest null arm (the
gateway emits card: null for a missing/unknown card); the TUI's only bare
dereference follows the same default path as a canonical card.
* fix(desktop): align billing inputs to the sm control height
The three billing inputs used an ad-hoc h-8 (32px) next to size=sm
buttons (24px). They now use the control system's size=sm with a
py-[3px] compensation for the input's real 1px border — buttons draw
theirs as an inset shadow, so sm alone still sits 2px taller. All five
controls in the buy row now measure 24px.
* fix(desktop): plan-card actionability + billing view-model hardening
Code-quality review of the Billing revamp (PR #68722).
BLOCKING — a top-tier subscriber (only downgrades/current below them) opened a
plans grid with zero enabled actions AND no portal link. The plan card gated its
in-app button on `tiers.some(state !== 'current')`, which counts the (disabled)
downgrade tiles. It now gates on an actual UPGRADE being present
(`capable && tiers.some(state === 'upgrade')`); with no upgrade the card falls back
to its "Adjust plan ↗" portal link, and the bview=plans deep link (gated on the same
plan.action) falls back to overview.
Reviewer structural items:
- One "plans capability" verdict (personal + can_change_plan + subscription ok) is
derived once in deriveBillingView and threaded to BOTH derivePlanCard and
derivePlanTiers; the grid only mints upgrade actions when capable, so the invariant
lives in one place.
- BillingPlanTierView is now a discriminated union (`current` | `downgrade` w/
disabledCaption | `upgrade` w/ required action), and BillingPlanCardView is an
action-XOR-link union — deleting the `tier.action?.url ?? ''` and `plan.link?.url`
defensive branches in the consumers.
- `findCurrentTier(subscription)` replaces the repeated is_current||id predicate at
its three sites (plan card price, grid ordering, summary plan line).
- BillingView exposes named `paymentRow` / `topupRow` / `refillRow` instead of an
`accountRows[]` + three `.find(id)` lookups.
- The auto-refill row that edits in place carries an explicit `manageInApp: true`;
AutoReloadRow keys off it instead of sniffing the action label/url.
- tier-art header comment no longer cites an internal repo path; dead `?.` removed
from RowValue (via a destructured const) and the plan-card link handler.
Behavior is identical except the blocking fix. Billing suite 82/82 green; typecheck
(app/electron/e2e) + lint clean.
* refactor(desktop): adopt inline-review nits on the billing plan card
Resolves the inline suggestion threads:
- plan-card gate reads a named `hasActionableTier` = "a tile carries an action"
(union-safe `'action' in tier`, equivalent to the old upgrade-only check).
- re-narrow link/action inside the click callbacks (`plan.link && …`,
`tier.action && …`) rather than relying on outer narrowing.
Behavior unchanged; billing suite 82/82 green, typecheck + lint clean.
Complete the #65919 warm/live-payload fix across its sibling path and add
real-SessionDB cross-builder coverage.
- Child-watch (lazy) resume: the delegated-subagent watch window served
_history_to_messages(repaired_history) for its user-visible messages, which
collapses out persisted verification candidates just like the warm-payload
path did. Build the visible messages from the verbatim child-only display
projection (repair_alternation=False) while the repaired history still feeds
live replay; fall back to the repaired history if the display read fails.
- E2E cross-builder consistency (real SessionDB, not mocks): a persisted
verification candidate is collapsed out of the model projection but kept in
the display projection, and _live_visible_history now equals the eager
session.resume display projection (candidate present). Adds the combined
candidate + fully-flushed-second-turn case and a lazy child-watch handler
test that asserts the candidate survives in resp["result"]["messages"].
#65919 persists verification candidates (finish_reason=verification_required
/ verify_hook_continue) to state.db but collapses them out of the in-memory
model history via repair_message_sequence. The eager session.resume + REST
paths read the verbatim display lineage (candidate present), but the
warm/live-reuse payload (_live_session_payload) built its user-visible
messages from the collapsed in-memory model history — so switching to a
still-live session dropped the substantive verification answer that a cold
resume of the SAME session showed. That divergence is the cross-session
"substantive text vanishes on switch" class, and the direct sibling of the
resume-duplication regression fixed in #68149.
Reconcile the persisted display lineage (candidate-inclusive, the same
get_messages_as_conversation(..., include_ancestors=True) read the eager
resume + REST paths use) with the fresh in-memory tail in
_live_visible_history, so all three surfaces agree by construction while a
not-yet-flushed live turn is still shown. Extracted
_reconcile_display_with_live as a pure, DI-testable function (anchors on the
last persisted row's (role, text); appends only the uncovered in-memory tail;
trusts the DB display when the tail can't be anchored).
Tests: unit coverage for candidate-inclusion, freshness, empty/raising-DB
fallback, and the combined candidate+fresh-tail case. The existing freshness
guard (test_session_resume_live_payload_uses_current_history_with_ancestors)
stays green.
ingestBackendSkin returned early for name === 'default' even when
apply=true, so a real runtime switch to the default skin (/skin default
on CLI/TUI, or config.set display.skin=default) emitted skin.changed but
never repainted the desktop. 'default' is no-opinion on the PALETTE (the
desktop keeps its own nous default, so we still never register a converted
theme under it), but it IS a valid apply TARGET: setTheme normalizes
'default' -> nous, so switching back repaints to the desktop default.
Skip only the registry step for 'default' and let it flow through the
apply guard. Addresses Copilot review.
Element tokens (ui_tool/ui_thinking), skinnable diffs, and code-syntax keys
flow through buildPalette → adaptColorsToBackground instead of a hand-mapped
color block, so they inherit #20379's contrast/polarity machinery. thinking
and syntaxComment track the EFFECTIVE muted (banner_dim override included);
the skin's `background` feeds the surface (it also paints the terminal via
OSC 11); statusFg falls back through ui_text/banner_text. Tests assert the
routing/independence contracts rather than pre-adaptation hexes.
Code highlighting reused brand tokens (accent/text/border/muted), so it couldn't
be themed independently. Add syntax_string/number/keyword/comment skin keys →
syntax* theme tokens (defaulting to those brand tokens, so defaults are
unchanged) and point the highlighter at them. Documented in the element→key map.
Changing a single color kept wrecking the rest because the agent hand-authored a
new skin (often from `default`, which has no `background`, resetting the terminal
to black). Add `hermes skin set <key> <hex>`: edits the ACTIVE skin's one key in
place (a built-in is forked into an editable copy carrying its full palette), so
everything else — background included — is preserved. Plus `skin use` / `skin
list`. The skill now points tweaks at this command instead of hand-authoring.
Changing one color ("make the tool ● cyan") forked `default` — which has no
`background` — so applying it reset the terminal to its own (black) default and
dropped the active skin's palette. Teach the skill to edit the active skin's file
in place for a tweak (watcher repaints on the mtime bump), and to fork a built-in
only by carrying its full palette. Hard pitfall: never fork `default` for a tweak.
Theming was semantic-only: the gold tool `●` was `accent`, shared with
headings/links/chevrons, so "recolor tool calls" was impossible and the agent
had no key to point at. Add `ui_tool` (● + tool spinner) and `ui_thinking`
(reasoning body) tokens that fall back to accent/muted — defaults unchanged,
but now independently settable. Make diffs skinnable too (`diff_*`), which
fromSkin previously hardcoded. Document the full element→key map in the skill so
Hermes knows which knob turns what.
The TUI inherited the terminal's background; now a skin's `background` paints the
whole surface via OSC 11 when a skin is applied, and clears back to the terminal
default (OSC 111) on revert and on exit (ridden in through resetTerminalModes).
Opt-in: a skin with no `background` leaves the terminal untouched, and the
restore only fires if we actually painted. Desktop already themed its own bg;
this closes the loop so Hermes owns its background on every surface.
A skin Hermes activates (`hermes config set display.skin X`) or recolors in
place now goes live on every surface (CLI, TUI, desktop) within ~half a
second, on its own — no `/skin`, no tool-hook timing, no user action.
A gateway daemon polls the resolved skin signature `(name, active-file mtime)`
every 0.5s and broadcasts `skin.changed` on any real move — a name switch OR a
live color edit to the active skin. It routes through the SAME path `/skin`
uses, so all surfaces repaint identically. The watcher seeds its baseline at
gateway.ready (stdio + ws) so it only fires on a real change; the `/skin` RPC
seeds the baseline too so it never double-broadcasts.
Subsumes the desktop's post-turn `config.get skin` poll (its skin.changed
handler already applies).
The skill told the agent to `patch` display.skin into config.yaml; a stray indent
corrupts the file and breaks the live gateway (the reported "/ menu broke"), and
a raw file edit never live-applies in a running CLI/TUI ("nothing happened").
Route activation through the safe writer (`hermes config set display.skin`), and
state plainly that a tool call can't hot-switch a running CLI/TUI — the user runs
`/skin <name>` (desktop still auto-repaints on the next turn).
Make the Python skin engine the single source of truth for a canonical theme
shape consumed by every surface, so a skin authored in $HERMES_HOME/skins/*.yaml
(by a user or by Hermes from a prompt) themes the CLI, TUI, and desktop GUI at
once — the theme analogue of the plugin SDK.
- @hermes/shared: canonical `HermesSkin` token shape + `SKIN_COLOR_TOKENS` enum,
consumed by both TS surfaces (TUI `GatewaySkin` and desktop dedup onto it).
- Desktop: `skinToDesktopTheme` resolver (skin → CSS-var palette, VS Code-style
derive-from-seed) + `backend-sync` that registers backend skins into the theme
registry (Appearance/Cmd-K/`/skin`) and applies on a real change. Seeds on
gateway.ready (never stomps a persisted pick), applies on skin.changed and the
post-turn `config.get skin` poll (catch-all for agent-edited config.yaml).
- TUI: `fromSkin` now maps the status bar + `background` keys it was dropping.
- Gateway: `config.get skin` also returns the full resolved palette (additive).
- Skill: `hermes-themes` teaches the agent to author + activate a skin.
Each surface keeps its own normalizing resolver (ansi for the TUI, CSS vars for
the desktop, prompt_toolkit/Rich for the CLI).
host.tsx collapses to one placement router over a shared render context, and the
grid-test app drops its width floor too (carrying the #20379 review rule). Final
formatting pass folded in.
A full placement grid so the agent can put a widget where it asks — dock-top/
bottom and corner zones, with corners as reserved rails that take real space
instead of floating over content. A per-widget error boundary plus lenient
ShimmerRows means generated widget code can't crash the TUI.
Reusable render primitives the SDK exposes to widget authors: sparkline/gauge/
hbars chart helpers (dimension-stable so live updates never resize the card),
an Accordion for expand/collapse sections, animated shimmer loaders, and a
streams demo that no longer reserves a phantom icon column on unfocused titles.
Hermes can write its own widgets: a loader discovers $HERMES_HOME/tui-widgets/*.mjs,
fs.watch hot-loads them the moment they land (no restart), and a tui-widgets skill
teaches the agent the contract and the openWidget-at-register auto-open recipe.
Load/error/remove events announce themselves in the transcript; a lazy intro
skeleton covers the first paint.
