**CRITICAL fixes**
- Header: note UNIVERSAL_SUBSTRATE_ROADMAP.md no longer exists on disk;
add note that TODO_MAP.md may lag this file
- §11: replace dead cross-reference with accurate statement; mark full
census reconstruction as Phase 0 deliverable
- Phase 0: split into completed infrastructure vs pending Lean work;
explicitly note `USTSM_State` does not yet exist in any Lean file
**ERROR fixes**
- §1: retract unverified "2,634 models" figure; replace with measured
1,126 ingested equation rows (source: equations.csv 2026-05-18)
- §6 Invariant 7: clarify Q0_64 universality is a Phase 0-1 design
goal, not a current enforced fact; note Bind.lean uses Q16_16
exclusively by design ("all values require integer component for
gradient computation") — no contradiction, different scopes
- §8: expand Semantics/Semantics description to reflect 946+ entries
(not a handful of named modules); update §4-Infrastructure/infra/
description to reflect Rust-only state (Python shims removed)
- §12 Credential Gateway: remove reference to deleted credential_server.py;
credit rs-surface binary and credential.rs module
**WARNING fixes**
- §10 FPGA Hardware: change ✅ Synthesized → 🔄 Bitstream ready; add
"live hardware receipt pending" caveat
- Phase 4 heading: rename to clarify concurrent-with-Phases-2-3; add
explanatory note
**BLOCKED annotation**
- Immediate action #8 (Flash Tang Nano 9K): mark as blocked on physical
board + USB programmer
