Closes #12807. The one documented command that ties two existing laws together: t27b watch on the window's root spec, and on a save the ordinary make t27os -- the window execs its new binary itself (specs/t27os/hot_reload.t27). Docs only, zero foreign growth: the first attempt added a make target and the foreign-budget hook rightly refused it (the issue body tells that story). Measured 2026-10-27: an edit to specs/t27os/queen_dash.t27 while the watch ran produced a full rebuild ending built target/t27os/T27OS.app (build 7647, signed with -) with the open window hot-swapping -- 4 rebuilds in one session. phi^2 + 1/phi^2 = 3 | TRINITY

Summary by t27-bees

This PR documents an existing hot-reload workflow for t27os: running t27b watch on the window's root spec with a --then 'make t27os' hook triggers a full rebuild on spec changes, and the running window hot-swaps itself via its existing hot_reload.t27 mechanism. No code changes—only the run-local docs are updated to show the command that ties the two existing pieces together.

Worth a look

• docs/t27os/run-local.md:78–80 — The documented command target/release/t27b watch specs/t27os/glass_window.t27 -o target/t27os/glass_window.o --macho --then 'make t27os' assumes target/release/t27b already exists; a fresh clone would need make t27b (or equivalent) first, which the docs don't mention here.
• docs/t27os/run-local.md:81–84 — The loop depends on make t27os writing the new binary to the exact path the window watches (T27OS.app/Contents/MacOS/T27OS). If the Makefile output location ever shifts, the hot-reload breaks silently (window keeps running old binary).
• docs/t27os/run-local.md:85–87 — The note about the reverted t27os-watch make target references a "foreign-budget hook" that rejects Makefile growth; if that hook's criteria change, the documented rationale could become stale.
