concepts/tigertag-chip.md states that if one chip of a pair stops answering,
the survivor "still identifies the spool — and serves to repair the broken
one". The wiki never says how.
The mechanism makes the question sharper than it looks. A pair is bound by a
shared Twin Tag ID, which is stamped at write time. So repairing a pair
means writing a replacement chip with the surviving chip's Twin Tag ID
rather than a fresh one — which is not what a normal write does.
What needs documenting:
- The exact steps in Tiger Studio (and whether Tiger NFC Connect can do it at
all).
- Whether the replacement inherits the survivor's Twin Tag ID, or whether both
chips are rewritten with a new one.
- For a TigerTag+: the signature binds each chip's own UID, so a replacement
chip cannot carry the dead chip's signature. What happens to the + status
of the pair?
Raised while reviewing #28, which carried this as a TODO in the page body.
The TODO was removed; the gap is real and belongs here instead.
