F3: add computeDictationAvailability assertions for the read-only ∩ pre-sync
intersection (editable:false, inEditMode:true, showStatic:true) → read-only for
both isDisconnected states, pinning that lack of edit permission takes
precedence over the pre-sync reason (kills a mutant dropping `editable &&`).
F4: switching native disabled → data-disabled made a disabled mic hoverable — good
for the byline mic (shows the reason), but a consumer passing bare `disabled`
without a reason (AI chat's isStreaming) got a misleading, actionable
"Start dictation" tooltip on a click-rejecting control. Now: disabled + no reason
→ render the icon with NO Tooltip and a neutral aria-label; disabled + reason →
reason tooltip; enabled → "Start dictation". Click guard/data-disabled preserved.
F5: remove the dead "busy" DictationUnavailableReason (never produced) — union
member, its resolver case (folded into default), and the vacuous test assert.
vitest (dictation + editor-sync + dictation-group): 41 passed.

The dictation mic could be grey/disabled while silently showing "Start
dictation", and Mantine's native `disabled` set pointer-events:none so the
Tooltip never fired at all — the UI knew the cause but told the user nothing.
Runtime error strings were also duplicated verbatim across the two dictation
hooks.
- New dictation-status.ts: the single source of truth. A DictationUnavailableReason
enum (connecting/offline/read-only/unsupported/busy) + a DictationErrorCode enum,
pure classifiers (classifyGetUserMediaError / classifyTranscriptionError) and
resolvers (resolveUnavailableLabel / dictationErrorMessage). All user-facing
dictation strings are formed here; the verbatim server message still wins for
transcription errors.
- page-editor publishes dictationAvailabilityAtom { isEditable, reason } computed
at the source (editable/edit-mode/showStatic/collab status): connecting vs
offline (stuck) vs read-only. DictationGroup forwards the reason to MicButton.
- MicButton is reason-aware: a disabled mic shows the cause-specific tooltip. The
disabled-hover silence is fixed by marking disabled the Mantine way
(data-disabled/aria-disabled + click guard) instead of the native attribute, so
the Tooltip fires — applied to both the idle (reason) and error (errorMessage)
states.
- Both hooks route every error through the shared resolver (deleting the
duplicated transcriptionErrorMessage), and expose errorMessage for the tooltip.
Wording is byte-identical to each hook's original (incl. the batch hook's
DOMException name prefix and the verbatim server message).
- i18n: 3 new reason keys in en-US + ru-RU, and the previously-missing ru-RU
dictation error translations.
Tests: dictation-status.test.ts (all classifier/resolver branches, incl. server
message passthrough) + mic-button.test.tsx (disabled mic shows the reason text,
uses data-disabled not native disabled — fails against the pre-fix code).
vitest: 5 files / 32 passed.
