Pull duplicated rules into ui-tui/src/lib/subagentTree so the live overlay,
disk snapshot label, and diff pane all speak one dialect:
- export fmtDuration(seconds) — was a private helper in subagentTree;
agentsOverlay's local secLabel/fmtDur/fmtElapsedLabel now wrap the same
core (with UI-only empty-string policy).
- export topLevelSubagents(items) — matches buildSubagentTree's orphan
semantics (no parent OR parent not in snapshot). Replaces three hand-
rolled copies across createGatewayEventHandler (disk label), agentsOverlay
DiffPane, and prior inline filters.
Also collapse agentsOverlay boilerplate:
- replace IIFE title + inner `delta` helper with straight expressions;
- introduce module-level diffMetricLine for replay-diff rows;
- tighten OverlayScrollbar (single thumbColor expression, vBar/thumbBody).
Adds unit coverage for the new exports (fmtDuration + topLevelSubagents).
No behaviour change; 221 tests pass.
- List rows: pad the status dot with space before (heat-marker gap or
matching 2-space filler) and after (3 spaces to goal) so `●` / `○` /
`✓` / `■` / `✗` don't read glued to the heat bar or the goal text.
- Gantt rows: bump id→bar separator from 1 to 2 spaces; widen the id
gutter from 4 to 5 cols and re-align the ruler lead to match.
- createGatewayEventHandler: remove dead `return` after a block that
always returns (tool.complete case). The inner block exits via
both branches so the outer statement was never reachable. Was
pre-existing on main; fixed here because it was the only thing
blocking `npm run fix` on this branch.
- agentsOverlay + ops: prettier reformatting.
`npm run fix` / `npm run type-check` / `npm test` all clean.
The Write tool that wrote the cleaned overlay split the `if` keyword
across two lines in 9 places (` i\nf (cond) {`), which silently
passed one typecheck run but actually left the handler as broken
JS — every keystroke threw. Input froze in the /agents overlay
(j/k/arrows/q/etc. all no-ops) while the 500ms now-tick kept
rendering, so the UI looked "frozen but the timeline moves".
Reflows the handler as-intended with no behaviour change.
Adds a live + post-hoc audit surface for recursive delegate_task fan-out.
None of cc/oc/oclaw tackle nested subagent trees inside an Ink overlay;
this ships a view-switched dashboard that handles arbitrary depth + width.
Python
- delegate_tool: every subagent event now carries subagent_id, parent_id,
depth, model, tool_count; subagent.complete also ships input/output/
reasoning tokens, cost, api_calls, files_read/files_written, and a
tail of tool-call outputs
- delegate_tool: new subagent.spawn_requested event + _active_subagents
registry so the overlay can kill a branch by id and pause new spawns
- tui_gateway: new RPCs delegation.status, delegation.pause,
subagent.interrupt, spawn_tree.save/list/load (disk under
\$HERMES_HOME/spawn-trees/<session>/<ts>.json)
TUI
- /agents overlay: full-width list mode (gantt strip + row picker) and
Enter-to-drill full-width scrollable detail mode; inverse+amber
selection, heat-coloured branch markers, wall-clock gantt with tick
ruler, per-branch rollups
- Detail pane: collapsible accordions (Budget, Files, Tool calls, Output,
Progress, Summary); open-state persists across agents + mode switches
via a shared atom
- /replay [N|last|list|load <path>] for in-memory + disk history;
/replay-diff <a> <b> for side-by-side tree comparison
- Status-bar SpawnHud warns as depth/concurrency approaches caps;
overlay auto-follows the just-finished turn onto history[1]
- Theme: bump DARK dim #B8860B → #CC9B1F for readable secondary text
globally; keep LIGHT untouched
Tests: +29 new subagentTree unit tests; 215/215 passing.
