Brought the Merkle-AGI v7 formal substrate spec into the repo as
docs/_source/merkle-agi-dag-v7.rst (previously referenced only as the
un-version-controlled ~/Downloads/merkle-agi-dag_v7.txt). Section
structure converted to reStructuredText; inline math kept in the
source's literal notation; added to the docs/_source/index.rst
"Substrate" toctree (also added the pre-existing merkle-agi-v8-consensus
entry that was missing from it).
Folded ticket #000035's § 9.10 + § 9.10.1 (anchor PRG map φ_PRG;
dav1d-reviewed-final, little-endian, HMAC-SHA-512 / 32-byte seed) in at
their numbered positions, after § 9.9, with a .. note:: citing the
reference implementation (arborist/substrate/anchor_prg.py). #000035 ->
closed (Phase 1 + Phase 2 both landed); #000018 §9.2 ("which PRG?")
resolves to HMAC-SHA-512 with a 32-byte committed seed. Full upstream
v7 spec revision stays exogenous; this lands the amendment into the
tracked in-repo copy where future amendments also go.
(docs/TICKETS.md also carries the in-flight #000048 index-row update
from a concurrent session.)
