The operator restated on 2026-10-08 that all communication between modules goes over the bus. ADR 0255 §9 had the bar's block print the power module's file.

  • ADR 0260 (extends 0255): modules never name another module's path under /run or /var/lib; a block may show a state its contributor keeps (<module>.<name>, key = the machine); the controller grants the bar's holder the read of what the modules on its machine offer, so the bar names no module; the power draw is the power module's state draw, one value per machine, ttl 30 s; state chosen over events on bus load and meaning; the battery block stays the bar's own (it reads the kernel, not a module). Checked by the catalogue's new checks/paths, controller and module tests.
  • ADR 0255: a dated pointer note under §9.
  • To-be 42: a Changed 2026-10-08 paragraph, decision added.

Code: mesh-catalog #127 (same branch); the controller part goes up as a new PR on the same branch once #143 is merged. records.py, index.py, cycle.py, words.py pass. Do not merge without the operator's approval.

Delivery novox/hq@9afd6f89028c — delivered since 2026-10-08T14:09:45Z

Delivery plan — builds nothing: the change touches no module of the mesh's graph

Transitions

  • 2026-10-08 13:55 (new) → proposed (announced): novox/hq#212's head announced
  • 2026-10-08 13:56 proposed → checked (checked): the verdict names this commit
  • 2026-10-08 13:56 checked → ready (accepted): the gate passed or warned, and the repository's own check did not fail
  • 2026-10-08 14:09 ready → published (merged): on the trunk its modules follow: merged there, and its walk opened — or nothing for a walk to move
  • 2026-10-08 14:09 published → delivered (done): nothing for a walk to move

The commit's note under refs/notes/mesh-plan keeps every transition: git log --notes=mesh-plan.
