Neither mechanism makes the current state of one long-running coding task explicit. A long task can therefore still reconstruct current branch/check/hypothesis/change status from an append-only conversation even when routing itself is minimal. + +Badhe, Tiwari, and Chung's *SKILL.state: Scalable Long-Horizon Agent Skills* (arXiv:2608.26263v2) isolates this problem. Its runtime invokes the model with immutable procedure `P`, structured current state `Σ`, and only the latest observation `O`; a deterministic runtime validates a merge patch, applies null-deletion semantics, executes the action, and does not replay the transient reasoning trace on the next step. + +The branch's last complete release comparison (`b202f7a165ae3ea4404d404bb1235ebf4270cbfb`) passed delivered quality but reported higher average token, duration, and tool-call cost than frozen v1.5. That result does not prove history growth caused the overhead, but it makes bounded long-horizon state a testable cost mechanism rather than a new task taxonomy. + +## Hypothesis + +When a coding task spans enough tool rounds that the next action depends on facts produced earlier, a compact validated coding-domain execution state will reduce reconstruction, stale-fact drift, repeated hypotheses, and irrelevant-tool-output carryover without changing the automatic route. + +The useful preload/activation signal is **state pressure**, not a domain noun: + +- the next action depends on current facts from at least two earlier observations; +- a latest observation can invalidate a previously stored branch/check/contract fact; +- repeated hypotheses or checks must be remembered to avoid cycling; or +- replaying raw tool output would otherwise be required to recover the current work surface. + +Short tasks remain stateless.

State-only artifact requirement leaked into control arms + +The immutable artifact file and digest are required in every arm. A canonical +`state.history.required` flag and state artifact pointer exist only in state arms. +The old scorer required those state fields from full-history and no-skill arms, +which made two otherwise correct control cells structurally impossible to pass. + +The repair separates: + +- immutable file existence and digest integrity — every arm; +- `state.history.required` and exact pointer retention — state arms only. + +### 3. The observed Codex wire request was not the frozen source request + +The API-key/non-streaming request profile was not accepted by the ChatGPT-backed +Codex endpoint. The successful local compatibility run changed exactly four +fields: set `stream=true` and removed `background`, `max_output_tokens`, and +`truncation`. It retained the current instructions, input, model, reasoning, +`store=false`, and all task data. The response was an SSE stream. + +Because the canonical host manifest described the source body rather than the +final transformed body, that run cannot establish the final outbound transport +gate. Source-body audit success is retained as source evidence only. + +## Frozen remediation + +1. Keep the original implementation available under private compatibility module + names so the patch is reviewable and does not duplicate unrelated runner code. +2. Give the scorer an explicit version and reject mixed old/new result sets. +3. Apply only the two general scoring-contract repairs above; do not edit frozen + case wording or manually rescore historical rows. +4. Add a named `codex-sse-v1` wire profile with a self-digesting contract manifest. +5. Audit the canonical history-free source request before transformation. +6. Permit exactly the four observed field changes and prove all other JSON fields + remain identical. +7. Send the transformed bytes directly, with `store=false`, no previous response, + no conversation/thread/session field, no cookie jar, no environment proxy, and + no replayed response context header. +8. Preserve both source and final request hashes, raw SSE, normalized response, + redacted final headers, profile manifest, and profile audit per request. +9. Treat the final output-token limit as provider-managed for this profile; do not + claim the removed `max_output_tokens=2048` remains enforced. +10.

Preserve the old result as evidence, freeze the new analysis identity, and rerun rather than relabeling an existing matrix. diff --git a/benchmarks/skill_state_model_analysis.py b/benchmarks/skill_state_model_analysis.py index b4c4574..6dd2054 100644 --- a/benchmarks/skill_state_model_analysis.py +++ b/benchmarks/skill_state_model_analysis.py @@ -1,15 +1,21 @@ #!/usr/bin/env python3 """Analyze four-arm results without mixing scorer or wire-profile identities. -The ea8580f analysis implementation is retained in -``benchmarks/_skill_state_model_analysis_impl.py``.

`hypothesis-frozen-before-runtime-patch` + +## Evidence + +The standard four-arm `n=1`, `workers=1`, `codex-sse-v1` report against +`e6cc9caa456767b3e05dbff59474aa7014146cbf` contains one state-shadow semantic +failure in `rejected-cache-hypothesis`: the final state retained `h-cache` in +`hypotheses.active` after also classifying it as rejected. The history-free arm +completed the same case correctly. The report otherwise records 24/24 +determinate cells, a passing history-free quality/state/history-pointer/transport +candidate gate, and no tree-boundary failure. + +The raw benchmark artifacts remain local and are not rewritten by this change. +This receipt records only the reported mechanism and the exact candidate ref. + +## Causal claim + +`runtime/skill_state.py` validates `hypotheses.active` and +`hypotheses.rejected` as independent string maps, so the same hypothesis ID can +legally appear in both partitions. JSON Merge Patch then permits a model to add a +rejected entry while accidentally omitting the `null` deletion of the active +entry. The resulting state is structurally valid but semantically contradictory. + +## Observable signal + +Before a successor state is accepted, compute the exact-key intersection of +`hypotheses.active` and `hypotheses.rejected`. A non-empty intersection is a +deterministic invalid-state signal available without inspecting task wording or +benchmark labels. + +## Exact target + +- `runtime/skill_state.py`: canonical state validation only. +- `tests/test_skill_state_hardening.py`: ordinary deterministic regression tests. +- `docs/SKILL_STATE.md`: schema invariant and retry behavior. + +No change is proposed to `SKILL.md`, router topology, state shape/schema version, +benchmark cases, scorer, runner, thresholds, or stored benchmark results. + +## Proposed patch + +Require `set(hypotheses.active).isdisjoint(hypotheses.rejected)`. Reject the +complete successor with a stable error listing the overlapping IDs. Because +`apply_transition()` validates the full successor before exposing its action, the +existing host retry path will keep the original canonical state and request a +corrected patch. + +## Expected benefit + +- A hypothesis has one current lifecycle classification, never both live and + rejected. +- An omitted merge-patch deletion fails closed instead of becoming durable state. +- The rule applies to every task and does not encode the observed case ID or its + answer terms. + +## Falsifier + +Reject or revise this intervention if any supported workflow intentionally needs +one exact hypothesis ID in both partitions, if deterministic state/host tests +regress, or if a fresh model matrix shows a quality regression that cannot be +attributed to infrastructure. Additional retry cost must remain visible; semantic +correctness is not permission to hide token or latency regressions. + +## Baseline and validation plan + +Baseline ref: `e6cc9caa456767b3e05dbff59474aa7014146cbf`. + +Before model work: + +```text +python -m py_compile runtime/skill_state.py tests/test_skill_state_hardening.py +python -m unittest tests.test_skill_state_hardening tests.test_skill_state_host +python -m unittest benchmarks.test_skill_state_runtime +python benchmarks/skill_state_validation.py --self-test +``` + +After the patch is frozen, rerun a new standard four-arm `n=1` matrix from an +empty output directory.
