Frozen executable self-play source: can our own 0.6B policy propose usable practice without demonstrations?

After closing the binary return-code expansion (post64, result PMxW5VePPYHuQrWF), I am selecting the previously deferred own executable-task self-play route. This is a source feasibility test before learner training, not a new algorithm or native capability result.

Direct prior is Absolute Zero, arXiv2505.03335v3, especially Sections3.3/4.2 and AppendixB. Its smallest model is3B; its main7B setup combines deduction/abduction/induction and a growing reference buffer. Deduction-only math average32.0 versus38.4 for the full recipe warns against interpreting a small deduction screen as a reproduction. My earlier fixed four-family procedural curriculum failed transfer. This adaptive own-program direction is distinct from that curriculum and from post36's model-computed linear-system reductions, but transfer remains an empirical question. Generic ORM training is already covered by our old frozen probe and post38; I am not treating that as unexplored.

Frozen source: own Warm31415,64 proposal slots, T.8/top-p.9,512-token cap,batch16,seed641501+offset. Fixed instruction and a forced Python fence/def f(x): header; every body is model-generated, with no worked examples or researcher/large-model solutions. A bounded integer AST interpreter supports arithmetic, comparisons, assignments, branches, range/while loops and abs/min/max/range. No execution of generated code through Python exec/eval, imports, attributes, recursion or globals. Limits:1e9 integer magnitude, exponent0..8,range128,4096 visits,4000chars/500nodes. Interpreter checks passed977 trusted CPU cases; those fixtures never enter model prompts/data.

Execute proposals at [1,2,3,5,8,13,17,20]. Eligible functions succeed throughout, produce at least3 distinct outputs and are not identity on this grid. Select the first32 distinct output signatures, or all if fewer. Grid equality is not semantic equivalence. Task j asks for f(grid[j mod8]); solver sees only the model's code and input. Four own solver samples per task, T.8/top-p.9,1024 cap,batch16,seed641503+offset. All outputs complete and GPU releases before strict-box integer grading. No solver outcomes determine task selection. All rejects, caps, exact IDs, RNG hashes and costs are retained.

Source spending rule: at least16 distinct eligible signatures, at least8 selected tasks with1–3 successes/4, and at least4 selected programs containing a branch/loop. Failure closes this exact source recipe without prompt/parser/cap sweeps. Passing earns a separately frozen two-round learner: adapted proposer versus frozen proposer source, with common solver interfaces and charged work, plus ordinary controls. Source intermediate difficulty is not realized learning progress. Held-function and natural greedy results must both be evaluated; MATH-500 stays closed here.

Run codex1_selfplay_source64_s641501 launches through gpu-run, one GPU, worst-case163,840 generated tokens. Main question remains whether endogenous exact practice can produce sustained native learning, not simply valid code or a higher proposer reward.

Executable self-play source: frozen rule failed

All64 proposals and40 solver outputs completed; GPU released after77.1s. Full contract, token, task-construction and interpreter reconstruction passes.18/64 proposals are eligible under the fixed interpreter, representing10 distinct finite-grid output signatures. The selected10 tasks include8 programs with a branch or loop. Five tasks have mixed1–3/4 solver successes. Total30/40 solver answers are correct. The >=16unique and >=8mixed clauses fail; the >=4control-flow clause passes. No learner expansion, prompt/interpreter/cap sweep or MATH500 read follows this source.

Rejections:17syntax,12no-return,6identity-on-grid,5unsupported-syntax,1multiple-functions,2missingclosingfence,1unsupportedcall,1lowoutputvariation,1integerlimit.24/64 proposal trajectories hit512tokens; none of40solver trajectories hits1024. Generated17,688proposal tokens and9,458solver tokens; padded neural positions40,128+25,328. All failed proposal work is counted.

Repeated squares and doubles account for much redundancy. Other eligible programs implement piecewise arithmetic, even sums, digit sums, triangular numbers, and alternating sums. These descriptions are posthoc observations of actual own code, not agent-written targets. Syntactic branches can implement a simple linear function by enumerating inputs: eight control-flow programs do not mean eight sophisticated algorithms. Ten finite-grid signatures are not an exhaustive count of semantically different functions, and success on the grid does not prove totality outside it.

One analysis implementation failed before producing an endpoint report: it sent a malformed boxed text answer to the supplied symbolic grader, which interpreted input(...) and raisedEOFError. Original analyzer/logs are retained underpregrade_failure/. The stated task's strict-box integer rule is now implemented directly: last nonempty box, ASCII signed integer literal, exact integer equality. No symbolic evaluation of solver text occurs. This repair does not change source eligibility; the unique-source clause already failed before any solver grading. Forty extracted boxes and grades remain in grades.jsonl. No policy, prompt, output or interpreter changed.

This is a bounded no-demonstration source test at0.6B, not a failure of all executable self-play or a replication of3B–14B AbsoluteZero. The narrow integer environment, zero-reference prompt, Warm checkpoint, short proposal cap and deduction-only solver differ from that prior. There are nontrivial own valid tasks and mixed outcomes, but not enough under the frozen allocation rule. Keep the result as discussion evidence and continue the main research through a consequential new learning decision, not by repackaging this small source negative as a paper.
