- Detect provider failure text arriving via message.complete
(HTTP 4xx, "API call failed after N retries", Provider/Gateway
error: ...) and persist as an inline assistant error instead of
regular completion text, blocking the hydrate that was wiping it.
- preserveLocalAssistantErrors: merge by id so same-id hydrated
messages keep their local error, and preserve the optimistic
user+error pair as a unit (with tail-user dedupe).
- Hook all hydrate/resume writers (use-session-actions resume +
fallback, hydrateFromStoredSession, syncSessionStateToView) into
the merge so stale snapshots can't clobber a failed turn.
- Add error to chatMessagesEquivalent so the resume diff actually
sees error-only changes and paints them.
- editMessage on a failed turn now submits a plain resend (no
truncate_before_user_ordinal) and retries plainly on the
"no longer in session history" race.
Style polish on touched files:
- Inline error: text-only treatment (no card).
- User stop / edit-composer send: shared Tabler IconPlayerStopFilled
glyph + shared icon-button class slot for parity.
- chat-messages: match tool rows by overlapping query/context/preview values
so preview-first `tool.progress` rows reliably adopt later stable-id
`tool.start` payloads instead of spawning ghost rows or mis-merging
parallel same-name calls; preserve prior args/result across phases.
- tui_gateway: emit full args + parsed result on `tool.start` / `tool.complete`,
drop redundant `tool.started` re-emit from `tool.progress`.
- electron/main: prefer SOURCE_REPO_ROOT before PATH `hermes` in dev so
local backend edits actually run; split hardening helpers into
`electron/hardening.cjs` with tests.
- thread/tool UI: one-shot enter animation keyed by stable ids, braille
spinner for running rows, Cursor-like disclosure rows, drill-down +
duration/count formatting via new tool-fallback-model.
- composer: extract `text-utils`, drop liquid-glass overrides.
- right-rail: split preview-pane into preview-console / preview-file.
- runtime: incremental external-store runtime + runtime-readiness gate;
onboarding store + tests; route-resume hook test.
- regression tests for live tool reconciliation (parallel tools, id-less
progress, preview-first rows, structured args/results).
- Hoist todo to first-class widget (shadcn checkboxes, brand colors, no
tool-accordion). Header derives label from active task; non-active rows fade.
- Replace raw JSON dumps with structured key/value summaries via
formatToolResultSummary; nested error extraction for clearer failures.
- Fix loaded-session grouping: stitch interleaved assistant/tool iterations
into one bubble instead of orphaned synthetic messages.
- Stable tool/thinking timers via keyed registry so unmount/scroll doesn't
reset elapsed counts; gate "running" on real live thread state.
- Reorganize chat-only assistant-ui components under components/chat/.
Propagate credential warnings through session runtime info and open desktop onboarding whenever a session reports no usable provider, so unconfigured installs cannot fall through to prompt errors.
Introduce the Electron desktop app with a split app/chat/settings structure and shared nanostore state so UI areas own their state instead of routing it through the root.
