**P1-1 — the `Invalidated` arm published the panel context on the
document wire.** Real bug, and the live half of the routing defect: the
semantic peer has ONE statusline slot, so emitting an
authoritative-empty payload for every context replaced the document's
with the panel's. Now filtered by document-window identity exactly like
the `Ready` arm; a panel's own clear belongs to `PanelFrame` in 2B.
Pinned by `invalidated_statusline_clears_only_the_document_not_the_panel`,
which reproduces the reported shape — two targets instead of one — when
the filter is removed.
Honest note on the `Ready` arm: its identity selector is **defensive**,
not independently falsifiable today, because the document context is
captured first so "first context for my frontend" happens to pick it.
Rather than leave that as a silent dependency,
`the_semantic_fan_out_captures_the_document_first` pins the order and
says why it matters.
**P1-2 — round-1 finding 3 was not closed; four of my pins were
vacuous.** All four confirmed and fixed:
- The statusline consumer test discarded `render_frame`'s output. It now
observes the WIRE payload from a v18 peer with a registered provider,
and asserts non-emptiness so it cannot pass by emitting nothing.
- The terminal test compared two NON-terminal buffers, so both routings
answered `false`. The document window now holds a REAL terminal, so
the routes disagree; reverting `semantic_terminal_key` fails it.
- The decorations test used different buffers and an empty selection —
again the same answer either way. The panel now displays the declared
buffer with a non-empty selection while the document has none.
- #1/#3/#21 had no discriminating pin at all. Their only production
caller is `dispatcher_loop`, which no test can drive, so this extracts
three named seams the loop calls — `document_buffer_to_follow`,
`document_cursor_byte`, `peer_displays_buffer_as_document` — and pins
each.
Also newly pinned: #2 the lazy CRDT upgrade (the census's sharpest
case), #7 `Viewport` aligning WITHOUT taking focus, and #9 a focused
terminal panel not suppressing the document viewport.
**Every one of the nine pins was falsified by revert.** Two needed a
second attempt after the first bite came back green.
**P2-3 — stale docs.** `StatuslineEvaluationTarget::Semantic`'s
documentation described evaluating only the focused window; it now
describes the document-plus-side fan-out, the capture order, the
identity-selection requirement, and that `active` reports actual focus.
The ledger's Stage 2A entry is corrected to five commits, 2,014 CRDT
tests, and 16 acceptance tests.
Two clippy findings the refactor introduced were fixed:
`document_buffer_to_follow` is `crdt`-gated to match its only caller,
and the `CursorByte` guard collapses into one `if`.
