Delete the two byte-identical local formatBytes copies from the chat-attachment
modules and repoint all call sites at the canonical lib/utils/format-bytes.ts,
which its own doc comment asks new code to use.
The copies had no upper clamp (>= 1 TB rendered "1 undefined") and no NaN or
negative guard (NaN rendered "NaN undefined"). Size labels now carry one
decimal ("10.0 MB" instead of "10 MB") because the canonical helper does not
strip a trailing zero; unit and e2e expectations updated to match.
* chore: revert agent subscription usage in settings and chat tooltip
Reverts #1697 (55c8b461b). The subscription usage plugin now covers this,
so the built-in Settings > Agents section and the context-doughnut tooltip
rows are no longer needed.
Conflicts resolved to preserve later work on the same files:
- token-usage-display.tsx/.test.tsx: kept the pinnable tooltip (#1869),
the rebuilt context-window layout (#1741), and the ACP/API source row
(#1752); removed only SessionUsageRows and its imports.
- settings/agents/page.tsx: #1741 moved <AgentUsageSection /> above the
pre-existing <Separator />, so the revert missed the JSX; removed it
and kept the separator.
- agent-usage-section.tsx/.test.tsx: deleted (later changes were cosmetic
tweaks to the section itself).
Office-side subscription surfaces (dashboard quota card, agent detail
QuotaCard, internal/agent/usage clients) predate #1697 and are untouched.

* fix(usage): keep #1697 client fixes when reverting its UI surface
#1697 bundled two things: the Settings > Agents section plus doughnut
tooltip rows, and a set of genuine bug fixes to the underlying provider
usage clients. Reverting it wholesale threw away the second group, which
is still live code behind the office dashboard quota card and the agent
detail QuotaCard.
Restores the client layer to its post-#1697 state (billing.go, cache.go,
client_claude.go, client_codex.go, fileutil.go, types.go and the two
client tests), fixing the defects CodeRabbit flagged on #1940:
- billing type is recomputed per call again instead of being frozen for
the process lifetime by sync.OnceValue, so login/logout is observed
without a backend restart
- usage cache regains fetch coalescing and short negative caching, so a
provider outage no longer means one outbound call per request
- Claude usage parses float utilization and the richer limits[] array
instead of failing to decode
- Claude token refresh patches only claudeAiOauth in a decoded map and
writes atomically via temp+rename, preserving unknown keys in the
credentials file the real CLI shares
- Codex reads tokens.access_token rather than a nonexistent flat token
field, and its doc comment matches the ~/.codex/auth.json path
The removed UI/API surface stays reverted: GET /api/v1/agents/usage, the
host usage lister, the settings section, and the tooltip rows.

Subagent cards keyed their auto-expand on `isActive || Boolean(resultText)`.
Silent (Auggie-style) subagents return a result_text but stream no child tool
calls, so `resultText` stays populated forever and the card rendered
permanently expanded, unlike subagents that emit child tool calls (which
collapse to their header + metadata row on completion). A render-phase reset
also wiped any manual collapse the moment result_text arrived.
Key auto-expand on the running state alone and drop the reset, so completed
subagents collapse consistently and the result text is one click away. Add
component coverage for the silent-subagent collapse, expand-on-click, and
manual-collapse-persists paths.

* feat(plugins): add chat-input-actions slot for plugin toolbar icons
Let plugins render icon buttons into the chat composer toolbar, beside
the model picker, mic, and send button, via the existing named-slot
mechanism (registerComponent). The host mounts the slot in both the
desktop and mobile toolbars and forwards { taskId, taskTitle,
activeSessionId, sessionIds } as slotProps — the active session plus
every kandev session id on the task. Resolving a session id to an
agent/ACP transcript id is left to the plugin (server-side, via the Host
data API); the host only propagates ids.
Docs (PLUGIN-API.md, public plugins/plugins-authoring) document the new
slot and its props.

* fix(plugins): read store optionally in chat-input-actions slot
ChatInputPluginActions read the app store via useAppStore, which throws
outside a StateProvider — breaking existing toolbar tests that render the
composer in isolation. Switch to useOptionalAppStore (fallback to no
sessions) so the slot never hard-requires a provider.
Also: gate the slot behind hideAgentControls to match the other
session-specific toolbar controls, drop a redundant String() coercion,
tidy a dangling docs reference, and cover the taskId=null path.

* fix(scripts): launch dev-isolated backend via __backend subcommand
The kandev binary became a bundle launcher with the restart supervisor
(ADR 0019) and exits without KANDEV_BUNDLE_DIR when invoked bare; the
isolated dev instance must run the backend entrypoint directly.

* feat(mcp): session spawning, sibling messaging, and renameable tabs
- spawn_session_kandev spawns an additional agent session on an existing
task (default: the caller's own) via LaunchSession(IntentStart), with
optional agent_profile_id (defaults to the spawner's profile) and a
session name; the initial prompt carries spawner attribution and reply
instructions.
- message_task_kandev accepts an optional session_id to target a specific
session, enabling same-task sibling messaging. Explicit targets are
pinned through dispatch so the idle-path primary-session re-resolution
cannot reroute a sibling message back to its sender (regression-tested).
- task_sessions gains a name column (migration ordered after the
agent_execution_id-drop rebuild), a session.rename WS action, and inline
tab rename UI; custom names take precedence over derived agent/model
labels across the tab, agents dropdown, mobile list, chat header, and
dockview panel titles.
- Inter-session messages stamp sender_session_name into metadata so the
sender badge shows which session sent the message.

* fix(mcp): address review findings on session spawn/rename/messaging
- include name in task-session DTOs (list + full, no omitempty) so
persisted tab names survive list hydration and clears propagate
- sanitize sender task/session ids embedded in <kandev-system> blocks
- reject cross-workspace spawn targets; require sender_task_id
- truncate session names by runes, not bytes
- distinguish not-found from internal errors in message target lookup
- guard TabRenameInput blur-commit after Enter/Escape resolution
- cap optimistic rename length client-side and toast on rename failure
- add tests: spawn launch-failure and cross-workspace paths, renameSession
API client

* fix(mcp): round-two review fixes for spawn/rename lint and hardening
- extract spawn validation/authorization helpers (cyclop/nestif limits)
- make stripSystemTag replace until stable to block nested tag evasion
- load session before rename so a durable rename can never skip its
broadcast; surface lookup failures to the caller instead
- drop redundant sessionLauncher nil check (guarded registration)
- add maxLength to the rename input matching the server cap
- add tests: nested sanitizer evasion, spawn rename-failure tolerance

* feat: surface agent subscription usage in settings and chat tooltip
Adds live subscription rate-limit visibility for Claude Code and Codex:
- GET /api/v1/agents/usage lists per-agent utilization windows (plan, percent,
reset time) for host agents with subscription credentials; ?fresh=true
bypasses the 5-minute cache with a 15s per-provider clamp.
- Fixes both existing usage clients: Claude parsed float utilization as int
(decode failure) and now reads the richer limits[] array incl. per-model
weekly windows; Codex read a nonexistent auth.json field and response
headers - now reads tokens.access_token, parses the body windows, and
refreshes OAuth tokens on 401. Token refresh persists without dropping
unknown credential fields.
- Settings > Agents gains a Subscription Usage section; the chat context
doughnut tooltip shows the session agent's windows, fetched fresh on hover.
- Shared UsageWindowRows component (bars, Good/High/Critical status,
reset countdowns) keeps settings, tooltip, and office surfaces consistent.

* fix: recompute agent billing type on every read
Subscription billing detection for Claude and Codex was cached with
sync.OnceValue for the process lifetime, so logging in with OAuth after
the backend started never flipped billing badges or office usage checks
until restart. Detection now re-reads the credential files on each call
and reuses the usage clients' HasSubscriptionCredentials checks. Also
adds a regression assertion that fractional-second resets_at timestamps
parse under the RFC3339 layout.

* fix: address subscription usage review feedback
- serialize empty utilization windows as arrays, not null
- sanitize per-agent usage errors in the API (raw provider errors are
logged server-side; they can carry credential paths/response bodies)
- persist refreshed CLI credentials via atomic temp-file rename
- keep previous settings usage on transient refresh failure; drop stale
tooltip usage (and its memo) when a fresh fetch fails
- add controller tests for SubscriptionUsage mapping and fresh propagation

* fix: coalesce concurrent usage fetches and guard codex token refresh
- serialize usage-cache fetches per key with a double-checked lock so
concurrent fresh requests make one provider call instead of a burst
- reject codex refresh responses with an empty access_token instead of
persisting them and wiping working credentials
- pin the usage-rows reset fixture 30s under the day boundary so the
formatted value is deterministic on fast runners
Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
* fix: coalesce failed usage fetches with short negative caching
Concurrent lookups after a fetch error each retried the provider once
the per-key lock rotated. Failures are now cached for 15 seconds (never
longer than the caller's staleness bound), so bursts share one error
result and the provider gets a breather before the next retry.
Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
* fix: keep stale usage through failed refreshes and skip caching cancellations
Track the last success and last failure independently in the usage
cache: a failed fresh refresh no longer evicts a still-valid success
(non-fresh callers keep the stale value while fresh callers share the
recent error), and a caller-cancelled context no longer records a
negative entry that would penalize other callers.

* test: synchronize concurrent usage-cache tests with a channel barrier
Replaces the sleep-widened race window in the coalescing tests with a
started/release barrier per the backend testing guidelines, and dedupes
the two concurrent-caller tests into one helper.
