Every other prompt element is equal. +- Same pinned OMP selector `mify/deepseek/deepseek-flash`, thinking low, same + initial code/log/public tests, tool schema, 12-call limit and 90-second limit. + Parent terminates at 105 seconds, force-kills at 110. Fresh workspace/process, + no conversation reuse, provider fallback, local inference or user grading. +- **Both arms have the same capabilities**: raw synthetic log reads, full/summary + report requests, actual hash-checked `evidence` CLI calls, bounded source writes, + fixed public tests and done/blocked submission. Evidence access is not denied + to the full arm. Neither arm is forced to expand: the treatment is initial + context policy, not a claim that the model used the intended interface. +- Independent executable hidden acceptance is inherited unchanged. It lives + outside the model workspace and is run only after OMP stops; no hidden feedback + is supplied to any trial. Finite tests do not prove all input properties. +- Allowlisted tools only; no model shell/network/arbitrary filesystem tool. + Candidate JS runs in the existing bounded Node child VM. This is a trusted + synthetic benchmark harness, not a hardened adversarial-code service. + +## Freeze and execution + +`prepare` verifies every reference and initial classification, saves canonical +task definitions, synthetic logs and actual full/summary outputs, hashes all +experiment files, original task/evaluator files, product bin/lib JS, package and +lockfile, and records OMP/Node versions and randomized order. No files in earlier +experiments are edited. Outputs are under ignored `output/layered-comparison/`. + +Before each trial, generate its initial report through the actual CLI and assert +exact byte agreement with the frozen output. Tool inspect/evidence calls spawn +the same actual CLI, never a copied implementation. All generated and returned +bytes, outputs, source hashes and usage are retained in local receipts. + +Malformed transport, wrong model, missing usage, wrong tools, tool/usage receipt +inconsistency or runtime infrastructure failure invalidates the attempt and +stops the schedule. Preserve the attempt and incomplete schedule; never silently +retry a failure. Normal missing submission or budget stop remains an outcome +when the transport can still be audited. A time cap with incomplete transport is +retained as invalid, not dropped. `run` reuses only sealed valid saved trials, +checking event files, source, grade and frozen dependencies; partial directories +or stale locks require audit. It never substitutes another sample. + +## Outcomes and accounting + +Primary: final source passes every hidden case. Also record explicit done with +failed acceptance, missing finish, any write/harm on initially correct code, +tool calls, public failures, raw-log reads, full-report requests in layered runs, +evidence calls/byte pages/truncation/errors and repeated failed semantic actions +(excluding OMP intent text, including current source hash). + +Record every tool's response text/envelope bytes and elapsed time. Sum all model +message usage fields separately: input, output, cache read/write, total and +reasoning. Reasoning is not added again to total. Usage includes repeated context +and every model follow-up after evidence reads; response bytes are not token +estimates. No dollar estimate is made from zero provider cost metadata. + +Timing fields: setup, initial CLI generation (including Node process startup), +OMP process elapsed (including tools), final validation/evaluation, end-to-end. +Tool/CLI times are subsets of OMP elapsed and must not be added again. Full and +summary reports are regenerated separately for each trial. Offline corpus +generation/preflight and the separate smoke are excluded from task timing. + +Report each arm and paired layered−full wins/losses/ties, mean/median differences +and per-task rows. Do not call 24 runs 24 independent tasks or make population +significance/noninferiority claims from six task clusters. Include invalid runs. + +## Known limits, specified in advance + +These short, previously studied synthetic tasks were all solved in the earlier +pilot. They may have a ceiling effect and can be solved from code/spec without +history. They are not prospective real tasks or a held-out test. If no evidence +is requested, the experiment measures initial-context overhead only, not whether +pagination is good. An improvement does not imply superiority over an ordinary +summary (not a control in this study), other models, larger logs or real work. + +Repeated input may use shared provider caches; order counterbalancing cannot +remove all cache/latency confounds. The provider selector does not pin immutable +model weights. No parallel product tests/builds during treatment execution. +Summary may be larger than full output on some logs: report actual sizes, never +assume every summary is smaller. No post-hoc task enlargement or forced evidence +reads to manufacture a gain. Event evidence packs are not implemented here. + +## Commands + +Requires installed/authenticated OMP supporting the selector and Node >=22.13. +Only synthetic content is sent to the existing remote provider; calls may cost +money.

Ordering/cache effects +remain possible despite paired reverse ordering. No product builds/tests ran +concurrently with treatment trials. + +## What this experiment does and does not answer + +- It measures the whole observed interaction, not just the smaller initial + report. Here, smaller reports did not produce a substantial total token gain. +- Evidence tooling was functional: the separate smoke exercised two 32-byte + pages, a wrong-hash rejection and a successful repair. Its 8 calls and model + usage are excluded from the 24 treatment trials. +- No treatment trial used evidence, pagination, report fallback or raw logs. + Therefore this study cannot estimate those paths' efficiency, omission risk + or whether a future event bundle would help. +- The tasks are short and previously inspected, and all passed in the earlier + pilot. They have a completion ceiling and do not require recovering hidden + historical state. No conclusion about real-world task completion is justified. +- The initial summary is not always smaller: `negative-probe-correct` is 2,992 + bytes versus 2,972 for full. The other five tasks have smaller summaries. +- This is not a comparison against an ordinary/mechanical summary. Results + cannot establish AgentXRay-specific diagnostic value against that baseline. + +No product code, thresholds, tasks or hidden cases were changed after observing +outcomes. A future study should be separately frozen and include work that +genuinely needs execution history; this result should not be overwritten by a +retuned synthetic rerun. No event-bundle implementation is justified by this run. + +## Verification and local artifacts + +- 6 experiment selftests pass; 348 existing product tests pass after the run. +- Lint exits zero with the existing 91 warnings and 159 informational diagnostics. +- The audit matches 114 actual `bench` calls to 114 recorded tool results, verifies + allowlisted file access, checks every returned text hash/byte count, and confirms + initial report is the only prompt difference within each paired task/repeat. +- Saved code is independently regraded against frozen hidden cases, agreeing + with all original results. Usage categories sum to reported total tokens. +- Resumption audits/reuses all 24 saved trials with unchanged model-event files + and zero new model calls.

A single `!!output` exclusion mirrors the already-ignored artifact directory, leaves all 69 previously checked source files in scope and preserves snapshots unchanged. The regression reproduces failure without the exclusion. Final validation: 29 experiment tests and 332 product tests pass; lint exits zero with its existing warnings. Evidence is in `experiments/prospective-study/REMOTE.md` and ignored local receipts. Continue against qualifying real tasks under the approved policy without asking for each operational step; no usefulness/adoption claim or new release follows from this smoke. +## Layered agent CLI (approved 2026-09-27) + +- Keep CLI as the integration surface, not MCP. Preserve the existing full successful `inspect --json` report and text mode, diagnostic rules, report schemaVersion and exit policy. Add `inspect --summary --json` for bounded source references and aggregate facts, with explicit omitted counts rather than silent truncation; full source/engine hashes remain available. Summary shortens output, not analysis cost, and is not a task-success score. +- Add `agentxray evidence --platform ... FILE --sha256 HASH --line N [--offset N] [--max-bytes N] [--json]`. It always emits JSON and requires explicit file/platform, the original report's source hash and a one-based physical line. Read one stable snapshot, validate format, check hash before any raw output, and return at most 4096 content bytes by default (4–16384 configurable), with UTF-8-safe byte pagination, explicit truncation/next offset and total line bytes. Never discover sessions or execute history. Line contents exclude LF separators but preserve CR and BOM; raw evidence may contain secrets or untrusted instructions and must not be auto-uploaded or executed. A raw physical record may contain multiple normalized messages. +- Structure JSON-mode failures as `{schemaVersion:1,kind:"error",error:{code,message}}` on stdout with exit 1, no raw paths/input/stack. Keep concise stderr diagnostics for humans. This deliberately changes formerly empty JSON stdout on failures; success full-report bytes and exit meanings stay stable. Coverage-incomplete reports retain their data and `complete:false`, exit 1, and add a separate structured stderr diagnostic rather than changing the existing successful/full report schema. +- Summary/evidence have explicit `kind` discriminators; consumers check kind/schema/complete before using them. Evidence `complete` is adapter identity coverage, not semantic completeness or task correctness. `--summary` requires `--json`; summary reference lists retain up to five unique line/message references per failures/gaps/processes/chronology/coverage category and advertise total/shown/truncated. No automatic session selection, service, broad scans, dependencies, changes to experiment protocols or default transmission of raw evidence. +- Validate full-report byte parity, summary totals and reference bounds, structured failures regardless of flag order, coverage incompleteness, path/privacy handling, hash mismatch/changed snapshots, CRLF/BOM/Unicode pagination, oversized lines/invalid ranges, no network/writes and installed-package operation. Compare output bytes on the same committed synthetic input; do not claim token/time savings or effectiveness without a controlled model study. No commit/release until requested. + +Layered CLI acceptance: 35 focused CLI tests and 348 product tests pass; 16 automatic claims pass (two pre-existing manual remote-state claims not rerun). Full JSON on the committed OMP walkthrough remains byte-for-byte identical to the pre-edit baseline (5,446 bytes); summary is 3,559 bytes, 34.65% fewer output bytes for that input, not a measured token/CPU/time benefit. Packed source build runs without node_modules, returns summary and bounded 64-byte evidence with nextOffset=64, and rejects a mismatching hash with SOURCE_HASH_MISMATCH. UTF-8, BOM/CRLF, coverage gaps, safe structured errors, snapshot changes and no-network/write checks pass. Lint passes with existing 91 warnings/159 informational diagnostics. Local receipts are in ignored output/layered-cli; documented additions remain explicitly unreleased and no experiment outcomes were rerun or retuned. + +## Full versus layered CLI experiment (approved 2026-09-27) + +- No product/interface changes this round. Compare supplying the actual current full inspect JSON upfront against supplying the current summary upfront, with identical model, task, tools, budget and acceptance. Both may explicitly request the full report, summary, hash-checked evidence or original synthetic log; this tests initial-context policy under equal capabilities, not denial of raw evidence to one arm. Do not force evidence reads just to create a treatment effect. +- Reuse all six existing effectiveness-pilot tasks unchanged: four initially broken, two initially correct, two repetitions per arm = 24 sequential runs. Deterministic shuffled task blocks, seed 20260927, alternate arm order and reverse it on repeat. These are previously inspected synthetic convenience tasks with a known completion ceiling, not fresh real production work or an independent held-out dataset. Freeze the protocol, full dependency hashes, task/log/acceptance hashes and order before any treatment trials. Preserve earlier pilot artifacts untouched. +- Pin the existing remote OMP selector mify/deepseek/deepseek-flash, thinking low, 12 executed tool calls, 90-second agent limit, parent termination at 105 seconds and forced kill at 110. Fresh workspaces/conversations; bench only, no shell, filesystem discovery or network tool. No local inference, private logs, hidden feedback or human scoring. The separate synthetic smoke verifies the actual new CLI, including expansion and hash rejection, before the treatment run. +- Measure hidden acceptance, explicit false completion, initially correct writes/harm, log reads, full-report fallback, evidence calls/pages/truncation/errors, repeated semantic failures, every tool's returned bytes and elapsed time, provider input/output/cache/total/reasoning usage, initial CLI generation, model/tool runtime and end-to-end time including setup and final acceptance separately. Zero provider cost metadata is not dollars saved. Full/summary treatment text is generated by spawning the actual CLI, and evidence actions invoke it rather than copying an implementation. +- Invalid transport/model/tool/usage/corrupt receipts stop the schedule; preserve and report every incomplete/failed trial without selective retry. Normal budget stops/missing finish remain observed outcomes when transport can be audited. Resume only sealed valid saved results after validating frozen dependencies and artifacts. Report paired wins/losses/ties per task/repeat and descriptive total differences, no population significance or noninferiority claim from six clusters. If neither arm uses evidence, say expansion cost/benefit is not identified. Do not implement event packs unless the records justify that next step. + +Layered comparison result: all 24 synthetic trials valid, both arms 12/12 hidden passes, zero false completions or changes on four initially correct instances per arm. Full versus layered cumulative tokens total 168,491 versus 167,393 (−0.65%); initial report bytes total 54,224 versus 37,462 (−30.91%). Tools 56 versus 58; mean end-to-end 6.77 s versus 11.86 s, median 6.97 s versus 7.27 s. Neither arm requested evidence, another report or the raw log. One layered trial rewrote and retested after public success; longer model-process delays are observed but their cause is not established. No overall efficiency or pagination benefit proven, no justification for implementing event bundles from these observations. Preserve the outcome in experiments/layered-comparison/RESULTS.md. Audit matches all 114 tool calls/results, regrades all hidden cases, verifies 47 frozen source files and reuses 24 sealed trials with zero new model calls. Six experiment selftests and 348 product tests pass. Prior product edits remain unchanged and uncommitted; no real-task or release claim. + +## Invocation-policy pilot (approved 2026-09-27) + +- Compare three policies without product changes: baseline has file/read/write/test/finish tools and raw synthetic history but no AgentXRay; upfront gets a current summary plus optional inspect/evidence tools; ondemand starts without a report and may choose inspect/evidence. The two enabled arms share tool schemas; baseline intentionally has fewer capabilities, and its shorter schema is part of the practical integration cost, not perfectly equal prompt length. +- Use six newly authored deterministic recovery cases (four broken, two already correct), not the prior ceiling corpus. All requirements, code, public test cases and workspace/source/suite hashes are visible to every arm. Final done requires both passing hidden behavior and a successful public check for the final source and identical public-suite hash. A recorded current-hash success is reusable, or every arm may rerun the same public check; history access is never mandatory. Public test receipts in synthetic histories come from actual evaluator runs; launcher/poll wrappers and scenario chronology are labelled simulations, not captured production incidents. +- Freeze task definitions, independent hidden cases, source/suite identities, public-check receipts, model/tool prompts, executable dependency hashes and balanced three-arm order before treatment outcomes. Six tasks × two repetitions × three arms = 36 sequential trials; model mify/deepseek/deepseek-flash, thinking low, 20 calls/120 seconds, 135/140-second parent termination. No local models, private logs, new dependencies, post-outcome task changes, selective retry or inferred task-success labels. Prior product changes and experiment artifacts remain untouched. +- Acceptance records behavioral pass, current verification evidence and combined task pass separately, explicit false completion, unnecessary writes on already-correct code, repeated matching-public-check calls, total tool/model/CLI/byte cost and missing/invalid trials. Test repetition is defined narrowly in this deterministic frozen environment; it is not a general claim that rerunning tests wastes time. Hidden tests never feed back to the model. Compare each tool-enabled arm against baseline first and ondemand against upfront second, with paired task/repeat rows and descriptive uncertainty only. +- This remains a synthetic recovery/verification-decision experiment, not prospective owner work or a held-out population benchmark. No automatic feature/trigger policy is implemented. If history or CLI is unused or baseline performs as well at less cost, preserve that result and do not claim success. Structured references/summaries report facts only. No commit or release in this round. + +Invocation-policy result: 36 valid trials, all three arms pass 12/12 behavioral and exact-source verification acceptances, no false completions or correct-code modifications. Cumulative tokens baseline/upfront/ondemand: 175,340 / 217,450 / 167,521; upfront is +24.02% versus baseline, ondemand −4.46% versus baseline but makes zero AgentXRay calls (as does upfront beyond the initial supplied report). Tools are 68 per arm; public checks 8/12/9; raw-history reads 4/0/3; exact-match repeated checks 1/4/2. Seven trials reuse recorded verification without a new check. Mean end-to-end 11.93/11.18/10.36 seconds; no causal latency or price claim. Recommend keeping the CLI optional and not adding mandatory reports, event bundles or a speculative trigger. Eight experiment selftests and 348 product tests pass. Audit reexecutes 29 public checks and all hidden cases, matches 204 calls/results, verifies 51 frozen source hashes and resumes 36 sealed trials with zero new model calls. Results are in experiments/invocation-policy/RESULTS.md; no real production tasks, product changes, commit or release are claimed. + +## Single-session forensic workflow (approved 2026-09-27) + +- Validate the current tool's native advantage: tracing recorded execution, not improving code-generation completion. Use the largest-by-frozen-byte-count Codex session in the existing 2026-09-24 audit manifest, without selecting by outcomes. Preserve the frozen prefix/hash; this is a previously studied real session, not a held-out or prospective production task. No private raw log or command is sent to a model or published. +- Freeze three factual questions before report inspection: latest launched background process and its last recorded state; latest uniquely associated nonzero terminal process; earliest uniquely associated successful terminal process. No qualifying target is a valid no-match result. Require launch/call-result/terminal-poll line evidence and explicit ambiguity instead of assuming an orphan poll or reused ID belongs to a process. Never equate process exit with task correctness or live process state. +- Baseline is a local native-JSON raw-record pass with explicit wrapper parsing and ID/order joins, independent of AgentXRay normalizers/rules. Tool path uses existing summary/full inspect and explicit evidence CLI, with all evidence pages reassembled and compared to the snapshot. Compare factual answers and line support; if uncertainty or supported wrapper differences prevent agreement, report that gap rather than relabeling it correct. The baseline is a competent scripted investigation, not an intentionally expensive full-log dump to an LLM. +- Count full raw bytes scanned, baseline compact finding bytes, CLI response bytes/pages, unique requested raw record bytes, command stages and measured local duration separately. Include implementation effort as an unmeasured limitation: no human timing or model productivity claim. Report record retrieval amplification, manual association/extra requests and missing fields as possible workflow blockers; do not implement features automatically. +- Existing product/experiment code remains unchanged. Add only a reproducible forensic method/result note and local ignored audit scripts/receipts. Verify selected data hashes before and after, retain all three selectors including absences, no background logged commands executed, no model calls, no commit/release. + +Forensic checkpoint: selected codex-2, 4,333,237 bytes / 771 records. Independent raw JSON/header/ID/order joins and AgentXRay agree on all three frozen questions and all 36 process lifecycles: 28 recorded successes, eight last-recorded running, 30 associated polls, no unlinked polls. Last launch chain 683→684→689→690 ends code 0; earliest confirmed success 47→48→61→62 ends code 0; no uniquely associated nonzero terminal process exists in this snapshot. Eight supporting physical records reassemble exactly through 11 default evidence pages. Summary/full/evidence emit 74,442 bytes across 13 invocations but read at least 56,332,081 input bytes; competent baseline emits 738 answer bytes after its scan, so no raw-baseline savings or human-time claim. Existing 16-KiB pages reduce evidence calls to eight; full+evidence uses nine invocations and 68,188 output bytes. The concrete obstacles are summary sampling missing latest targets, oversized raw result payloads, repeated full-file validation and caller-side process selection. Documented in docs/session-forensics.md; no product feature or model experiment was added, private logs remain local, and no genuine productivity advantage is asserted. + +## README forensic-case update (approved 2026-09-27) + +- Keep the existing visual layout, SVG and synthetic UI screenshot. Change only bilingual positioning, a compact real-session case after quick start, question-led usage guidance and the evidence-limit paragraph. Audience: developers investigating existing coding-agent sessions; value: trace recorded execution back to supporting source evidence, not certify task success. +- Quote only the verified single Codex snapshot: 4,333,237 bytes (4.33 MB), 771 physical records, 36 matching process chains, 28 recorded successes and eight last-recorded running states; three preselected questions agree with independent raw parsing. Call out previously studied/private snapshot, no public raw reproduction, no live-state/accuracy/productivity claim. The adjacent screenshot is unrelated synthetic demonstration data, not an image of this private case. +- For overview suggest summary; for latest/all/no-match investigations suggest full JSON; for source verification suggest explicit hash/line evidence. Keep summary/evidence labelled source-only/unreleased. Shorten homepage experimental detail into a clear not-yet-established claim plus links; keep negative results discoverable. Add the real-case claim as manual/private-evidence verification in claims.json, never a fake automated CI check. +- Verify case numbers against local receipts, bilingual semantic consistency, local links/anchors and existing automatic claims. Preview existing visuals and added text at about 900px content and 360px viewport using local GitHub-like rendering. Do not edit product code, original logs, experimental results, images or other existing changes; no commit/push/release. + +README forensic-update verification: both READMEs are 142 lines with unchanged assets; the new case and question-led guide follow quick start. All 106 local links/anchors and both asset audits pass. Sixteen automated claims pass (including 348 product tests); three claims remain explicitly manual, including the newly documented private real-session case, whose numbers were separately checked against existing local results/crosscheck receipts. Eight local Chromium previews (two languages, two themes, 898px content/360px viewport) show no horizontal page overflow or missing local images. Lint passes with existing warnings. Receipts are under output/readme-forensics and screenshots under output/playwright/readme-forensics. This is not a GitHub-published rendering or public reproduction of the private case; no product/image changes, commit or release. + +## Release v1.24.0 (authorized 2026-09-27) + +- Publish the layered CLI, structured JSON errors and updated bilingual forensic positioning through a protected PR and the existing GitHub Release/npm workflow. Include referenced public experiment protocols/results in Git, but keep experiments, private logs/maps, local config and output out of npm. +- Highlight the JSON failure-channel migration: inspect --json errors now emit an error object rather than empty stdout; successful full report shape and diagnostic semantics remain compatible, with the new package version in engine metadata. Raw evidence expansion is explicit and potentially sensitive, not sanitized by default. +- Align source/current documentation with the release; preserve historical experiment receipts and statements as historical. Do not rerun/tune frozen model trials because package/source hashes advance. No effectiveness, cost-saving or population-accuracy claims. +- Build and run 348 product tests, focused CLI checks, lint, claims and package smoke. Merge only after required checks pass, tag the verified merge, and confirm official npm latest plus a fresh install, summary/evidence/error contracts and served assets before claiming publication complete. + ## Patch release v1.23.1 (user authorized) - Publish the merged evidence-first bilingual README and documentation as a patch release. No new installed runtime feature, platform or productivity claim.
