The 1026-line de-novo response arrives after #000070 was corrected
from fixed Anchor6 to generic AnchorN/WorldDimensionGrammar. The
bridge concept is valid and necessary; the Joseph6-coupled framing
is now wrong. Same pattern as #000070's review: §§1-8 preserved as
the design log of what was reviewed; new §0 carries the corrected
spec.
Verdict matrix (12 rows in §0 decision table):
✅ GO: bridge concept (Agreement / Translation / Embassy), Phase 1
doc-only, bridge_seed@v1 deferred to Phase 2, no audit_mode,
no SQL, bridge atlas Phase 3.
❌ REWRITE: #000070-as-Joseph6-sibling → AnchorN sibling;
chain_id=governance_policy_hash → composite ChainRoot
with optional v7-W fields (null sentinels for language-
only QA chains); single event_type='bridge' → typed
schemas per kind; privacy as Phase 3+ footnote → Phase 1
vocabulary (4 classes); #000059 "already-shipped"
overclaim → proposed/structurally-aligned unless repo
confirms.
❌ REJECT: doc-only Phase 1 flipping #000013 to "kernel_in_progress"
— correct status is "bridge_grammar_specified"; kernel_
in_progress is for actual kernel landings.
Five bridge outcomes (was three):
Agreement — grammars match on invariant set
Translation — hash-pinned adapter proves the mapping
Embassy — foreign object hosted with limited rights
Quarantine — NEW: bridge attempted, invariant validation FAILED,
record the rejection so future attempts see what broke
No-bridge — NEW: grammars genuinely incompatible, explicit
declaration that no bridge will exist
Composite ChainRoot identity:
chain_id = SHA256(canonical({
chain_id_version, history_root, governance_policy_hash,
canonicalization_version, schema_version, chunking_version,
world_manifest_hash, world_dimension_grammar_hash,
axiom_pack_hash, optional_verifier_policy_hash
}))
Language-only chains: three v7-W fields are null sentinels →
chain_id collapses to existing identity. v7-W chains: all mandatory.
Phase 1 deliverable (corrected):
1. Substrate-paper extension §"World-bridge grammar" (5 outcomes
with typed witness shapes + composite ChainRoot + privacy
vocabulary + sovereignty rule + #000070 cross-ref + retro-
validation appendix with corrected shipped/proposed framing)
2. Optional namespace stub arborist/world/bridge/__init__.py
(STATUS = "namespace_reserved")
3. NO kernels / NO bridge_seed canonicalization / NO SQL / NO
cache-key dimension / NO new audit_mode / NO verifier change /
NO KATs
4. #000013 status bumps to "bridge_grammar_specified", NOT
"kernel_in_progress"
Sovereignty rule survives unchanged (chain law local, bridge law
treaty-only, no bridge overwrites native chain law — guard against
forced-unity failure mode). Hash-pinned translators survive
unchanged. Topic-named under arborist/world/bridge/ unchanged.
