Golden Chain v2.0: Immortal Self-Verifying Agent

Date: 2026-02-14 Version: 2.0.0 Status: Implemented & Tested

Summary

Golden Chain v2.0 adds Self-Repair Engine, Immortal Persistence, Evolution Loop, Phase G Verification, and 3 new QuarkTypes (filling u5 to 32/32). Quarks increase from 56 to 64 per query (+8 total, +1 per node on average). Verification gains Phase G (self-repair integrity). Combined: 8 provenance + 64 quarks = 72 immutable records per query. Export bumped to v4 (34-byte header).

What This Means

For Users

Self-healing chain: Broken quarks detected and repaired automatically
Immortal sessions: Chain state persists across restarts via SHA256 fingerprint
Evolution tracking: Each query generation improves fitness, adaptation visible in UI
64 quarks per query: Maximum audit granularity with self-repair and evolution tracking
4 new message types: REPAIR, PERSIST, EVOLVE, HEALTH visible in canvas

For Operators

72 immutable records per query = maximum audit granularity
7-phase verification = linear + DAG + phi-hash + cross-chain + phi-quantum + staking + self-repair
Self-repair: Automatic detection and fix of hash mismatches, low confidence, broken entanglement
Chain health reports: Total/healthy/repaired/broken counts with health_score
Full u5 QuarkType: All 32 slots used, no further QuarkType capacity without enum widening

For Developers

selfRepairChain() -- scan + repair first broken quark, returns RepairRecord
getChainHealth() -- returns ChainHealthReport with health_score
persistState() -- compute SHA256 fingerprint of all quark+provenance hashes
restoreState(buf) -- deserialize chain, increment restore_count
evolveChain() -- record EvolutionRecord with generation, fitness, repairs
selfRepairVerify() -- Phase G with 2 sub-checks
3 new QuarkType variants with classifiers: isSelfRepairQuark(), isImmortalQuark(), isEvolutionQuark()
SelfRepairState enum: healthy, degraded, repairing, repaired
SelfRepairType enum: hash_recompute, confidence_restore, entangle_fix, chain_rebuild
RepairRecord, EvolutionConfig, EvolutionRecord, ImmortalState, ChainHealthReport structs
Export v4: 34-byte header, backward compatible with v1/v2/v3

Verification Phases

Phase	Check	Description
A	Linear chain	Genesis zero-hash, recompute all hashes, verify chain links
B	DAG integrity	Entanglement bounds, backward refs only, gluon_verify has refs
C	Phi-hash balance	XOR all hashes, mod-3 residue classes >= 2 of 3 present
D	Cross-chain	Node ordering non-decreasing, every provenance node has quarks
E	Phi-quantum	E1: phi-residue, E2: Lucas modular, E3: golden angle
F	Staking integrity	F1: share link fingerprint valid, F2: staking balance consistent
G	Self-repair integrity	G1: repaired quarks valid, G2: tvc_corpus_hash consistent

Self-Repair Engine

selfRepairChain():
  for each quark in chain:
    recompute expected hash
    if hash != expected:
      repair_state = .repairing
      fix hash, restore confidence to threshold
      record RepairRecord
      repair_state = .repaired
      return RepairRecord
  return null (chain healthy)

Repair types:
  hash_recompute    -- re-link prev_hash and recompute current_hash
  confidence_restore -- restore confidence to SELF_REPAIR_CONFIDENCE_THRESHOLD
  entangle_fix      -- reset broken entanglement references
  chain_rebuild     -- full chain rebuild from point

Conclusion

Golden Chain v2.0 transforms the agent into an Immortal Self-Verifying Agent. The 64-quark chain with 32 QuarkTypes (FULL u5) provides 72 immutable records per query. The self-repair engine automatically detects and fixes broken quarks. Immortal persistence via SHA256 fingerprint enables state recovery across restarts. The evolution loop tracks generation fitness and adaptation. Phase G (self-repair integrity) adds 2 verification sub-checks for a total of 7 verification phases. Export format v4 (34-byte header) preserves backward compatibility with v1/v2/v3. All 83 golden chain tests pass, WASM stub synchronized, canvas updated with 4 new message types. The QuarkType enum is now at full u5 capacity (32/32 variants).
