f10-coder holds gitea-mosaicstack-f10-coder.token with write:repository scope and was
verified at mint by 'repo access returns 200'. It cannot push: collaborator lookup
404s and its own token reports push:false, pull:true.
Capability has three independent layers — token file (raw-API auth), tea login (tea
path), repository permission (actual write authority) — and satisfying two proves
nothing about the third. Scope bounds what a token may ATTEMPT; repository permission
decides what the user may DO.
The charter principle failing on the check meant to confirm capability: a 200 on a
READ was accepted as evidence of WRITE. written-unverified treated as verified, by
both provisioner and orchestrator, one layer above D-12.
RM-50's pre-dispatch check must assert effective permission for the intended operation
(permissions.push == true as that seat), not token existence or a read returning 200.
A capability check that cannot fail on a seat lacking write permission is itself an
inert gate.
