What v0.5 Is

v0.5 is the name for the intermediate build where ouroboros_infinity.py was added —
Stephen's ∞-loop directive given full implementation. It sits between:

• v0: 75 tests, hello_brain.py, v0 codex_root, receipt chain only
• v1 (r0513): 243 tests, all 8 new modules, inner agents, source-chain receipt

v0.5 was not tagged independently. The additions are tracked here.

Stephen's Directive (verbatim)

"i believe an amazing loop running like an infinite sign in the brain could be the answer
add the codex tail of the, in there and then whatever else you recommend
look at all my thesis instill the brain wire our brain with it all but never stop"

---

What Was Added: ouroboros_infinity.py

Module constants

LOOP_INVARIANT = "but never stop"

SZL_FORMULAS = {
    "F1":  "9-axis conjunctive AND gating — all axes ≥ 0.90, locked ≥ 0.95",
    "F2":  "5× byte-identical replay falsifier — determinism under SZL_FROZEN_TIME",

F1–F15 are the SZL thesis backbone — Stephen's intellectual system instilled directly into the loop.

Key classes and functions

Name	Description
LoopState	Pydantic model — serializable snapshot of loop state
CycleHead	Immutable head record — what seeds each cycle
CycleTail	Immutable tail record — what each cycle produces
LoopController	The ∞-loop engine — tick(), meditate_n_cycles()
build_thesis_corpus	Loads field_meditation corpus or uses synthetic F1–F15
meditate_n_cycles	Module-level convenience wrapper

The ∞-loop structure

current_head ──► tick() ──► CycleTail(tail_hash, receipt, eval_result, ...)
                                 │
                                 └──► next current_head = sha256(tail_hash + prev_head)
                                                              (the tail feeds the next head)

This is the Ouroboros: the serpent eating its own tail. Every cycle's output becomes the next cycle's input. The codex tail (tail_hash = codex_root of that session's receipts) is folded in directly.

Two lobes

Cycles alternate between CW (clockwise) and CCW (counterclockwise) lobes — matching the ∞ sign. CW = Perceiver, Predictor. CCW = Dreamer, Rememberer. Crossing = Proposer, Critic, Arbiter.

Key test coverage

Test	What it proves
test_loop_invariant	LOOP_INVARIANT == "but never stop"
test_szl_formulas_f1_through_f15	All 15 formulas present
test_loop_state_serialization	LoopState is JSON-round-trip stable
test_loop_controller_three_cycles	3 successful cycles, tail_hash non-empty
test_tail_feeds_next_head	Each tail_hash cryptographically seeds next head
test_meditate_n_cycles_replay_determinism	Same state → same output (5× identical)
test_loop_controller_pause_resume	Pause/resume preserves state
test_tier_scratchpad_no_signoff	SCRATCHPAD bypasses sign-off
test_loop_state_snapshot_roundtrip	State snapshot is JSON-serializable
test_continuum_hash_changes_each_cycle	Each cycle produces unique continuum_hash

Determinism: tail_hash Fix

The critical determinism bug in v0.5 development:

Problem: RAGReceipt.artifact_path stored tempfile paths (/tmp/tmpXXXXX.json).
These differed between process runs → tail_hash was non-deterministic.

Fix: Normalize artifact_path="" when computing tail_hash in ouroboros_infinity.py:

# In CycleTail hash computation:
normalized = receipt.model_copy(update={"artifact_path": ""})
tail_data = canonical_json(normalized.model_dump())

After this fix: 5× replay of agi_brain.py is byte-identical.

---

Thesis Corpus

build_thesis_corpus() loads from field_meditation/ if present; otherwise generates 15 synthetic entries from F1–F15. The corpus rotates deterministically via corpus_index % len(corpus) — each cycle ruminates on a different thesis formula.

Stephen's entire intellectual system (9-axis doctrine, Merkle receipts, Mamba-2, GRPO, Walrus, EvalGate, tiered autonomy, continuum-hash rail) is thus instilled into every cycle of the loop.

Continuity

• v0 replay hash (hello_brain.py): a8603d5de9f3c97d94d13b5e394424c2e18f1be352f98b097f43eee5947d90a0 — unchanged
• v0 codex_root: 15925d1558aa65bbfa3362a723a8ff57ad6c50be744dc2a0caefc91e066abfe4 — unchanged
• The ∞-loop addition did not break any existing tests.
