## Prompt

The user asked what work had been done so far, then authorized autonomous
work while AFK. The target was to scheme and prototype an actor-local gap
annotator from the `backfiller_deep_fixes` tip without mutating existing
branches. The user then clarified twice that the annotation IPC API must
remain available and should become more rigorous and `msgspec`-typed rather
than being removed.

## Generated code

> `git diff HEAD~1..HEAD -- piker/ui/_gaps.py`

Adds tagged gap request/reply structs, render-ready gap specs, vectorized
OHLCV timestamp-gap detection and chart-local overlay ownership.

> `git diff HEAD~1..HEAD -- piker/ui/_remote_ctl.py`

Adds strict Tractor gap IPC, `AnnotClient` stream mapping/locking and
owner-scoped endpoint cleanup while retaining the legacy annotation endpoint.

> `git diff HEAD~1..HEAD -- piker/ui/_display.py`

Starts the local 60-second overlay after display-state registration.

> `git diff HEAD~1..HEAD -- piker/ui/_interaction.py`

Routes `Ctrl+G` from the focused chart's existing async input loop directly
to the local controller.

> `git diff HEAD~1..HEAD -- piker/ui/_widget.py`

Stores the chart actor's local controller reference.

> `git diff HEAD~1..HEAD -- piker/ui/_annotate.py`

Keeps redraw repositioning isolated by FQME and synchronizes arrow geometry.

> `git diff HEAD~1..HEAD -- piker/tsp/_annotate.py piker/storage/cli.py`

Renames the remote annotation control type and context manager to the
client-oriented `AnnotClient` / `open_annot_client` interface.

> `git diff HEAD~1..HEAD -- tests/test_gap_overlays.py`

Adds deterministic detector, directional payload-schema, typed error and
msgpack roundtrip regressions.

> `git diff HEAD~1..HEAD -- tests/test_ldshm.py`

Updates storage CLI test seams for the renamed annotation client context.

## Generated architecture output

> `git diff HEAD~1..HEAD -- plans/opencode/chart-local-gap-overlays.md`

Documents ownership, startup, UI, strict IPC, refresh and branch landing
semantics.

## Verification output

Source resolution points to this worktree. The targeted regression passes,
Ruff reports no changed-file findings, `compileall` succeeds, `git diff
--check` succeeds and Tractor's strict gap payload decoder initializes.
