Integrates canonical `main` @ `cf54270` and closes every finding.
**P1-1 — a stale document `Pointer` stole focus from the panel.** Real
bug. `align_primary_document_window`'s unknown-buffer arm returned
`Some(window)` despite aligning nothing, so #8's activation focused the
document *before* `dispatch_pointer` rejected the mismatched buffer. It
now returns `None`: alignment did not happen, so no caller may treat it
as a document gesture.
Pinned through `handle_dispatcher_event` — the real dispatcher seam —
because the defect lived in the PAIR of alignment and activation, not
in either alone. **The first version of that test was vacuous**: an
unregistered session is dropped at `daemon.rs:1962` (#148's
membership check) before the aligner runs, so it passed with the bug
restored. It now registers a real semantic session and fails with
exactly the reported symptom, focus moving `WindowId(2)` →
`WindowId(3)`.
**P1-2 — the approved A2A-2 fan-out was missing.** The semantic target
returned one context. It now captures the primary document PLUS the
visible side window, each provider invoked once, with a
derived-hidden side omitted (Q#BP2b — no mode line to paint, so no
callback should run for it). The acceptance asserts `windows.len() == 2`.
This exposed a second defect the finding did not name: the consumer
selected segments with `.find(|w| w.context.frontend_id == frontend_id)`
— the FIRST context for the frontend. With two contexts that silently
depended on capture order and could have shipped the panel's mode-line
text as the document status band. `emit_statusline_segments` now takes
the document `WindowId` and selects on window identity.
**P1-3 — the census suite tested the authority, not the consumers.**
Confirmed: reverting a producer to `active_window_for` left all ten
tests green. Added consumer-level pins that drive the real producers
through `SemanticRenderState::render_frame` with a panel focused, plus
the terminal-declaration guard. Bite-verified: reverting the
`LineNumbers` routing now fails
`consumer_line_numbers_follow_the_document_not_the_focused_panel`.
**P1-4 — main integrated.** The textual conflict was `docs/active-work.md`
(both lanes rewrote the same region; the terminal-config lane is kept
whole and the bottom-panel heading updated). `src/editor.rs` auto-merged,
and the full gate suite was rerun on the merge result.
**P2-5 — the painter test was vacuous.** A fixed-point check that
survived deleting `window.text_view.render`. It now asserts each of the
four extracted outputs actually appears: buffer TEXT, the line-number
GUTTER (with line numbers explicitly enabled, rather than dropping the
assertion), the window MODE LINE, and a returned caret. Bite-verified
by deleting the render call.
**P2-6 — the stale fold-projection claim is corrected.**
`src/window.rs`'s `fold_projection` doc no longer asserts that a
semantic session never enters `paint_frame`; it records that the panel
band breaks that premise and that the extracted painters take the map
as a parameter.
Gates on the merge result: fmt clean; workspace clippy clean; 1,832
default + 2,010 CRDT library tests; Stage 2A acceptance 13; Stage 1 46;
statusline 8; m11_5 2; GPU initial target 14; terminal config 12;
folding Stage 2 48; vterm 1/2 10 / 6; M4 121; required GPU 202;
`git diff --check` clean. `vterm_stage3_acceptance::a37` remains the
pre-existing flake measured on the base commit.
