Four channels were bare string literals repeated across files, with the payload type supplied by each
caller. Neither hole errors: a typo yields a different, empty channel — publisher publishing into nowhere,
subscriber waiting forever — and a publisher and subscriber can simply disagree about the payload with
nothing to check them. defineChannel(name, initial) returns the hook, officerdev/src/channels.ts declares
the four, and every usePanelChannel call site in the repo now passes a shared constant.
files:refresh-signal was bumped two different ways: Date.now() at the Chat sites, setSignal((n) => n + 1)
at the FileViewer ones. The increment is wrong — useGlobal's functional setter applies against the value
captured at render, so two bumps in one render window both compute snapshot + 1 and the second writes the
same number as the first. Nobody re-reads and the file that was just written stays stale. Date.now() has
the same flaw at millisecond scale, and the four FileViewer sites (save, delete, extract, transcribe) sit
close enough to hit it. useFilesRefresh's bump is a module counter that never reads React state, so it is
right however many times it is called between renders, and it is identity-stable through a ref because
useGlobal's setter is a fresh closure every render and this goes into dependency lists.
system-settings:run-command is deleted. It had a writer once — 7c0b11c wired the AI harness installer to
it — and when that install moved server-side to POST /server-settings/chat-providers/install the write
went with it, leaving a channel whose only remaining writes were clears, a terminal pane nothing could
open, and a second layout nothing could select.
PanelComponentEntry's component, header and provider are typed with { panelId: string }, which is what
PanelSlot has always rendered them with. A no-prop component is still assignable, so no screen changed.
chat:active-session and preview:refresh are declared but still have no subscriber. preview:refresh has no
plausible one — the PreviewProvider that read it is gone from the repo — but both are published by the
chat panel, and that is not this branch's to change.
