### Scope The R3 verifier must return a JSON diagnostic when file access or declared packet integrity fails. This freeze-preparation PR requires valid digests/current-packet joins/carriers, corrects repeated binding counts, and handles missing, malformed or inaccessible inputs. The successor additionally protects filesystem metadata probes and CLI root resolution from `OSError` tracebacks. - Base commit: `06aca3df6c9ba0edea13719e4b7fb8169bba9838`, the corrected main target for this rebase. #900 landed at `36e36ea498e23ffd5bfc103035a2da883a6a08e4`. The reviewed predecessor of this micro-fix is `0a8589350f1a7b18823b231ef3ea81e865aaad79`; it includes the earlier `a3b8e60083c6e9f728bac9f2905b99c5304684db` corrections. - Lane: `lane:trading`. - Owned paths: the packet's verifier, README, ROW14 and three SHA256SUMS carriers; `tests/test_r3_verify.py`; and their evidence registrations. - All17 current normative joins must resolve to the declared current carrier target. Missing fields/targets, external redirection and unexpected mandatory-container entries fail. Valid optional external evidence remains an unverified boundary; the two declared null PIT-04 inputs remain unaccepted placeholders. - Both alternate carriers must equal `SHA256SUMS`. Nonregular inputs are rejected before opening. File reads, symlink/regular-file checks, optional-target probes and CLI root/default resolution catch `OSError` and return a named JSON error. Verification exits **0 on PASS, 1 on FAIL**. - Protocol, registry, allfiveR2contracts and runtime receipts retain landed-base bytes. No external evidence source is opened. Keep the PR draft for both micro reads, CI, the remaining J8/PTA disposition and the CC's cue; this does not freeze or accept strategy/data/identity evidence. The subsequent micro-fix adds direct tests for member bytes changed without resealing, a well-formed wrong ROW contract digest, and a join retargeted to another present member with its correct digest. JSON decoding now reports RecursionError and ValueError as named failures, and recursive traversal reports its own nesting-limit failure. Tests cover native deep JSON/large integers and deterministic decoder/traversal limits. The docstring and ROW source identify the actual `json.loads`/`hashlib.sha256` primitives, retain the CC-R3-1 lineage and local-only scope, and the unused `digest()` function is removed. Rebase head `58ea680098d0833b5e75fe8829c5167113726112` preserves the seven PR file bytes from reviewed head `e13d1a3c1aa7676b79240fa03cd4afb892d9c4a6` and rebuilds `manifests/evidence.json` from corrected main plus the seven owned registrations. The intermediate unpublished rebase onto `2ecce6ec` was replaced before the one push. The rebase requires both designated micro reads on its delta, green CI on this head and the CC's cue. Two further SFH disclosures: - `assert_cli_failure` gains optional `interpreter_args=()`. Its subprocess argv is `[sys.executable, *interpreter_args, SCRIPT, ...]`; the empty default preserves the prior invocation. The huge-integer regression passes `-X int_max_str_digits=4300` to make the child interpreter's limit explicit. - The verifier docstring and hash-bound ROW14 `verifier.source` replace the former CPython **v3.12.3** attribution (`json.load`/`hashlib.file_digest`) with **v3.13.16** (`json.loads`/`hashlib.sha256`). This is a source-attribution correction; no interpreter installation, runtime-lock change or historical receipt rewrite is performed. ### Explicit behavior and output changes 1. Symlinked **SHA256SUMS, SHA256SUMS.R3 and SHA256SUMS.R3B** are rejected, as are symlinked members. The former carrier handling followed symlinks. 2. A standalone field named **`sha256`**, without a path/artifact/pdf/receipt sibling, must be a **64-character lowercase hexadecimal string**. It is validated without becoming an internal join. 3. A value under a **manifest-named key** must be a valid hexadecimal digest string. Dictionary and list values there fail validation and are **not recursively walked**. 4. Every **`.json` carrier member must have an object root**, including optional members; array/scalar roots fail. 5. The JSON result adds **`internal_binding_count`** and **`binding_count_scope`**. **`internal_bindings` is deduplicated by source file and digest-pointer location**, giving 17 locations rather than 27 repeated checks for the current packet. **`manifest_sha256` can be null** when the canonical carrier/root cannot be read; **`semantic_checks` can be partial or empty** after an early failure. Those conditions accompany FAIL diagnostics and exit 1. ## SOTA sources - [python/cpython v3.13.16 json](https://github.com/python/cpython/blob/v3.13.16/Lib/json/__init__.py) and [decoder](https://github.com/python/cpython/blob/v3.13.16/Lib/json/decoder.py): installed parser/JSONDecodeError and the native interpreter used for returned failure behavior. - [CPython v3.13.16 pathlib](https://github.com/python/cpython/tree/v3.13.16/Lib/pathlib), [hashlib](https://github.com/python/cpython/blob/v3.13.16/Lib/hashlib.py), [re](https://github.com/python/cpython/tree/v3.13.16/Lib/re) and [unittest](https://github.com/python/cpython/tree/v3.13.16/Lib/unittest): filesystem predicates/reads, exact byte digests, whole-string validation and the native regression harness. The installed pathlib predicates may propagate PermissionError/ENAMETOOLONG; those operations now share protected diagnostic paths. - [Published verifier at36e36ea4](https://github.com/seathatflowsinourveins/native-agent-stack/blob/36e36ea498e23ffd5bfc103035a2da883a6a08e4/blueprints/us-equities/event-anchored-ranking/R3-VERIFY.py), [protocol](https://github.com/seathatflowsinourveins/native-agent-stack/blob/36e36ea498e23ffd5bfc103035a2da883a6a08e4/blueprints/us-equities/event-anchored-ranking/protocol.draft.json) and [ROW14](https://github.com/seathatflowsinourveins/native-agent-stack/blob/36e36ea498e23ffd5bfc103035a2da883a6a08e4/blueprints/us-equities/event-anchored-ranking/ROW14-SUBMISSION-R3.json): reference integration and normative schema. Existing `scripts/host_receipts.py:register_file` refreshes the dependent hashes. No new dependency or runner is added. - Designated GPT verdict SHA256 **406d3bee5bf70ad9617d6749c5206bcae30c7625c8ab683fae6f9b1e36ab53e2** and api-actions J8 silent-failure report SHA256 **3e63cf3b7621e1ae39edd756f12c592c329fa338d37dda08d78160b37d90d7f7** identify the reviewed failure paths and behavior/test gaps. This successor implements the released items; the PTA result and both micro verdicts remain separate. - CC micro-read SHA256 **192c02a0ff10b34dc4cb18b78a5833b9217fe24965639f73aa26b24c03459084** and J8 test-analyzer rerun SHA256 **53459435782bb7a5428b1da4a85e437d76d6cb0bfb58c3d43f89a3dccf763271** identify the released F1/F2/F10/F6/P3 micro items. The prior 40-case verification remains predecessor evidence; the new head requires its delta read, J8 micro, CI and the CC cue. - J8 micro report SHA256 **626fbe4ca7fe9071e803cf2313837cc0ae518e0da284af171262fb5b7533e2af**, section3: the two additional disclosures above. The report was hash-verified before use. ### Evidence-class table | Claim | Evidence class | Command / receipt | | --- | --- | --- | | Filesystem metadata/read/root-resolution errors return JSON FAIL/exit 1 | synthetic / local_integration | Each probe is exercised with PermissionError and ENAMETOOLONG through the CLI entry; native256-character member/reference cases also run. The predecessor reproduced2failures/8errors. | | New rejection branches and result shape | synthetic / local_integration | Symlink carriers/member, nonUTF8canonical carrier, malformed format/digest/path/duplicate manifest lines, standalone hashes, manifest-named dict/list and optional JSON-array cases. | | Exact committed packet remains valid | local_integration | Regression calls `VERIFIER.verify(PACKET)` without resealing and executes the native CLI on that same packet, requiring PASS/exit0 and17uniquejoins. | | Repository and registration consistency | local_integration | Named verifier/classification/pre-push/evidence-manifest modules, native carrier and `scripts/validate.py`; actual returned output retained. | | Scientific protocol/contracts/gates retain bytes | source_review | Native byte comparison with landed base and reviewed predecessor; only verifier/docs/hash-source metadata and dependent integrity artifacts change. | Fresh checks on the rebased committed head: `tests.test_r3_verify` **47/47**, `scripts/validate.py` rc0, native verifier PASS with **17 bindings** and nine semantic checks, and each of the three carriers **12/12OK**. The classifier41/pre-push16/evidence-manifest5 results below remain the retained predecessor runs; they were not rerun for this rebase. The PR packet/test bytes are unchanged, and CI acceptance remains pending on the new head. ### Local commands run ```sh nice -n 10 ionice -c2 -n7 timeout 600 python3 -B -m unittest tests.test_r3_verify nice -n 10 ionice -c2 -n7 timeout 600 python3 -B -m unittest tests.test_blind_checkout nice -n 10 ionice -c2 -n7 timeout 600 python3 -B -m unittest tests.test_pre_push_gate nice -n 10 ionice -c2 -n7 timeout 600 python3 -B -m unittest tests.test_evidence_manifest nice -n 10 ionice -c2 -n7 timeout 600 python3 -B scripts/validate.py python3 -B blueprints/us-equities/event-anchored-ranking/R3-VERIFY.py sha256sum --check SHA256SUMS git diff --check ``` Final verifier module:47cases; classification41, pre-push16 and evidence-manifest5. All returned rc0 on the implementation predecessor; the fresh rebase results are specified above. Validatorrc0; current verifierPASS,12members/17distinctbindings/9semanticchecks; nativecarrier12/12OK. Locally authored mutation/injection tests and exact-packet integration checks do not supply upstream scientific acceptance, either micro verdict or CI acceptance. ### Decision record The packet README records the verifier error/count contract, numeric exits and evidence limits. The chosen approach extends the existing stdlib integration, preserving its scientific inputs. Fresh GPT/CC micro reads, CI, any J8 micro required by the PTA result and the CC's cue remain pending. #867 is closed with a pointer to landed #900. No census count, fit, acquisition, vendor contact, purchase or broker action was performed. Sanitized returned command evidence remains with the custodian; private locators and protected study inputs are excluded from this PR.

…894) ### Scope - What this PR changes, in one or two sentences: adds `claude-pr-review.yml`, an on-demand, read-only review of one same-repository pull request head by `anthropics/claude-code-action` v1.0.247. A maintainer dispatches it from `main` with the pull request number and the exact head commit; the review goes to the job summary and nothing is posted to the pull request. It runs only while the repository variable `CLAUDE_PR_REVIEW_ENABLED` is `true`, so merging this starts nothing. - Effort (added 2026-10-08 at head a6d2379): `--effort max` in `claude_args`, because judgment work (designated reads, adjudication, pull request and security reviews, audits) runs at `max` under the command center's effort mapping, and every job records its level and reason. The level has to be in `claude_args`: `--restricted` ignores the settings files that would otherwise carry it, and Opus 5.5 runs at `medium` on the API when a request leaves effort unset. The bounds test now requires the flag; removing it fails the test. A loopback dry run of the installed 2.1.295 client with this workflow's `claude_args` sent `output_config.effort: "max"` on every request. - Fixes from the pre-cue read of the sibling #892 (2026-10-09, head d6f8909): the record names every behaviour of this new workflow: the trigger; the slug, owner, first-attempt and variable guards; the timeout and grants; the guard and binding exits; the head-as-data checkout and diff limits; the explicit action inputs `display_report` and `track_progress` (defaults in the pinned `action.yml`); and the 14-day usage artifact. The bounds step now uses an allow-list, fails on a start record without lists or on an empty result, and names each unmet bound. The review cut is character-safe and says when it cut. The step tests no longer skip without PyYAML. The 2026-10-03 cooldown waiver is cited. - Fixes from this PR's own pre-cue toolkit read (J8 on d6f8909, head 8e64120): - the empty paths array is now expanded safely on bash before 4.4; - a success without an execution file now fails the job; - `display_report` and `track_progress` are asserted; - the artifact name and the action-pin sentence are corrected, and the parity receipt's dependency on #892 is stated; - `claude-pr-review.yml:review` is now in both grant tables of ci-least-privilege; - the record states that a public run's summary is public. - Pre-cue toolkit read of this PR (J8 on d6f8909, 2026-10-09; `pr-test-analyzer` and `silent-failure-hunter`): every finding at confidence 80 or above, and its status at head 41c9c15. | Finding | Status at 41c9c15 | Fixing commit and evidence | | --- | --- | --- | | `pr-test-analyzer` 1 (90): the record names the wrong artifact | fixed | 8e64120: the record names `claude-pr-review-usage-<run id>-<attempt>`, the upload's name; 41c9c15 adds `test_the_usage_artifact_is_named_for_the_run_and_its_attempt` | | `silent-failure-hunter` 2 (88): the record and the workflow disagree on the artifact | fixed | the same two commits | | `pr-test-analyzer` 2 (85): `docs/github-automation.md` claims the harness audit's action pin | fixed | 8e64120: the bullet says the two pins differ until #892 lands | | `silent-failure-hunter` 1 (92): the same false claim (pin and federation variables) | fixed | 8e64120, as above; the four federation variables are the same | | `pr-test-analyzer` 3 (85): the headline evidence file is not in this PR | fixed | 8e64120 states that #892 adds it and lands first; 41c9c15 cites its `LR` entry field by field | | `silent-failure-hunter` 3 (80): "#897" and "two blocking findings" have no source in that receipt | fixed | #892 adds `target_pull_request`, `target_head`, `report_blocking_findings` and `report_sha256` to the `LR` entry (a marked 2026-10-09 amendment from the run's harness receipt); 41c9c15 cites them, calls the verdict the model's own, and states that the prompt and `claude_args` are unchanged from the run's workflow commit a6d2379 to that head (R5 later raises the two caps and the prompt's turn sentence; see R5 below) | - R4, debug logging set as a repository secret or variable (2026-10-09; the cc-native-practice lane's L3 read against `anthropics/claude-code-action` v1.0.247 practice): the guard binds `(secrets.ACTIONS_STEP_DEBUG || vars.ACTIONS_STEP_DEBUG) == 'true'` and `(secrets.ACTIONS_RUNNER_DEBUG || vars.ACTIONS_RUNNER_DEBUG) == 'true'` as booleans and refuses either before any token is requested; a test pins both bindings, and six weakened copies each fail at least one test. This is hardening: the action step already pins `ACTIONS_STEP_DEBUG: 'false'`, which is what the action's full-output switch reads. zizmor's auditor persona reports `secrets-outside-env` on the two reads; CI runs the regular persona with `--no-ignores`, which reports nothing. The R4 lines are byte-identical in #892, #894, #895, #896 and #909; R5 leaves them unchanged here. - The report notice at the cap (2026-10-09; the J8 micro read of #892): the publish step wrote with `jq -r`, which adds a newline, so a 60,000-byte report was announced as cut. It writes with `jq -j` now; a test publishes exactly 60,000 and 60,001 bytes, and a copy that writes with `jq -r` fails it. R5 adds the 59,999-byte case. - From the J8 micro read of 41c9c15 (2026-10-09; 4 of 6 listed findings fixed, PTA-3 and SFH-3 partly because the receipt the record cites was not in this tree): this PR now carries a byte-identical copy of `local-parity-receipt.json` (sha256 `ba498b82…`, the file #892 adds), so the citation no longer depends on which PR lands first, and the docs bullet states the action pin and the federation variables instead of comparing with the harness audit on `main`. - R5 (2026-10-09, head d1bcb6c, limited by the command center to correctness and test quality) adds a model-free step, `Remove symbolic links from the pull request head`, right after the head checkout: `set -euo pipefail; find pr-head -path pr-head/.git -prune -o -type l -exec rm -f {} +`. It raises the approved caps from measurement: `--max-turns` 12→30 and `--max-budget-usd` 3→5. The prompt's "You have at most 30 turns", the numbers step's bounds (1 to 30 assistant turns, at most $5, with matching messages), the header comment and `docs/github-automation.md` follow. The numbers step now counts each non-string tool-list entry as a forbidden tool named `non-string tool entry` instead of dropping it. The R4 guard lines, the deny list and the `github_token` input are kept exactly as at a1bc3bc. The test module goes from 33 to 41 tests. Eight are new: the symlink step's position and exact text; its behaviour on planted links to `/proc/self/environ`, `../.git/config` and a subdirectory, plus a re-run on a link-free head; a 59,999-byte report published whole; object, null and number tool entries refused and named; the prompt stating the `--max-turns` value; and the caps at 30 turns and $5 and just above. Changed tests pin the full `claude_args` list and `--settings` JSON exactly, assert the exact `if:` strings of the publish and numbers steps, run the guard with production's debug-off values (false/false/empty), and check that the 59,999-byte prefix before a cut character survives. All 28 weakened copies of the workflow fail at least one test with PyYAML present, as the hosted validate job has it; without PyYAML 15 of 28 do, because the pins sit in the PyYAML-only shape tests. The decision record gains a dated R5 section and names the R4 guard change in its what-changed paragraph. It corrects "Read denies for every `.git` directory" to "for the files under every `.git` directory". It restates the cap derivation and the expected cost per run, and withdraws the dry $0.70–$1.30 estimate, which was below the measured first-read cost. It adds the shared follow-up line, the shared `origin` URL sentence and two action sources. `manifests/evidence.json` is rehashed for the four changed files. - Sources of the R5 items: the command center's security read of a1bc3bc (the symbolic links, the closed flag list, the exact `if:` strings, the guard's debug-off values, the 59,999-byte prefix, and the stale guard sentence in the record); the command center's caps decision of 2026-10-09; the GPT designated read of #895, P2 (non-string tool entries, applied to all five W4 workflows); the cc-native-practice lane's third audit, P3-1 (the shared `origin` URL sentence). - Caps derivation: `LR`, a first read of #897 with this workflow's prompt and `claude_args` on the installed client, used all 12 of its 12 assistant turns and cost $2.23 ($1.87 by the client's estimate). So the need is above 12, and 2.5 times that floor gives 30 turns; twice $2.23 is about $4.5, rounded up to $5. Four delta re-reads (LR2 to LR5) used 5, 6, 7 and 6 turns and cost $1.75, $1.35, $1.54 and $0.73. A run is expected to cost about $1.9 to $2.3 for a first read and $0.7 to $1.8 for a delta re-read. - Filed as follow-ups before any enabling variable is set, not in R5: the security hardening from the 2026-10-09 read (debug-value widening, the tool-list shape apart from the non-string entry above, extra deny rules, token-source and guard-step assertions); the rest of F-02 (a non-empty tool list, checking the `tool_use` names); F-16 (the pins that run only with PyYAML). - Not run in R5: a fence smoke with a planted symbolic link, which needs a model run; any hosted run. On the first run, watch whether the action appends an `--mcp-config` that `--strict-mcp-config` still honours (the read's G3); the numbers step fails the run on any MCP server. - Base commit: `aba02ec3` (merge base at a1bc3bc and at d1bcb6c, which builds on a1bc3bc; as read at a1bc3bc, main had moved to `ebe6c223` with #890, #900, #897 and #907; only `manifests/evidence.json` overlaps, and the one rebase happens at landing) - Lane: `lane:foundation` - Owned paths touched: `.github/workflows/claude-pr-review.yml` (new), `tests/test_claude_pr_review_workflow.py` (new), `tests/test_workflow_policy.py` (one inventory entry, one exemption), `tests/test_workflow_security_coverage.py` (coverage set and one zizmor test), `docs/decisions/2026-10-08-claude-actions-pr-review.md` (new), `docs/decisions/2026-10-04-ci-least-privilege.md` (dated addendum only), `docs/github-automation.md` (current-practice bullet), `evidence/artifacts/claude-actions-fence-smoke-20261008/receipt.json` (new), `evidence/artifacts/claude-actions-fence-smoke-20261008/local-parity-receipt.json` (new; byte-identical to the copy #892 adds), `manifests/evidence.json` (registration, last commit). ### R6 (2026-10-09), at bd10ba3 - **Cost bound:** the budget × 1.10 = $5.50, from four measured J8 runs on a $5 budget ($5.46, $5.33, $5.16, $5.0007), re-derived after the first three hosted runs. - A budget stop at or under it publishes the text written before the stop, with a line naming the stop. - Publishing is gated on `!cancelled() && steps.numbers.outcome == 'success'`, because the action fails its own step on any budget stop. - **`--max-turns 30` removed:** the pinned action (`base-action/src/run-claude-sdk.ts:241-250` at 2dca132f, since 6ef6450f) fails a success whose `num_turns` exceeds it. - On Claude Code 2.1.295, `num_turns` counts transcript messages: 57 for 12 requests under `--max-turns 12`. That is a code reading plus a local measurement, not a hosted run. - The numbers step's 30-assistant-turn bound and the prompt's "at most 30 turns" stay. - **Job timeout:** 20 → 30 minutes. 30 turns at the measured pace (12 turns in 512,670 ms) take about 21.4 minutes before setup. #892 uses 30. - **Settings pins:** both compare canonical JSON, so `1` no longer passes for `true` (J8 R5 micro, N1, confidence 70). - **Record:** - the shared cost paragraph; - an upstream-issue draft (not filed); - the seven changed test expectations the J8 R5 micro found undeclared (U1–U7). - **Local checks at bd10ba3:** - `validate.py` and the manifest check pass (10,906 files); - six modules: 262 tests, OK; - this module: 44 tests (16 skip without PyYAML); - actionlint and zizmor are clean; - 39 of 39 weakened copies fail a test with PyYAML. - **Hosted checks at bd10ba3:** not read yet. ### SOTA sources - anthropics/claude-code-action, v1.0.247 at `2dca132ff0e0c4094ce6048b422c6915a071210b` (<https://github.com/anthropics/claude-code-action/tree/2dca132ff0e0c4094ce6048b422c6915a071210b>): `docs/security.md` ("Do not check out an untrusted ref into the workspace root before this action"; base ref at the root and head ref in a subdirectory), `docs/setup.md` (federation inputs; "a static credential takes precedence and federation will not be used"), `action.yml` (inputs and the `execution_file` output), `base-action/src/parse-sdk-options.ts` (argument parsing with `shell-quote`, default setting sources, debug forcing full output), `src/github/operations/git-config.ts` (git authentication in the root checkout; lines 129-134 write the job token into the checkout's `origin` URL when `allowed_non_write_users` is unset) and, new in R5, `src/modes/agent/index.ts` (lines 52-61, where agent mode calls that configuration). R5 read both files at v1.0.246 (`38c80c1`); the command center's compare of v1.0.246 and v1.0.247 changes only the bundled Claude Code version. - Claude Code 2.1.295, the version the pin installs, `claude --help`: `--restricted` ("removes the built-in tools that run commands or code ... and ignores user, project and local settings files ...

Activation is a separate step after landing: an owner sets `CLAUDE_PR_REVIEW_ENABLED` to `true`, then dispatches the workflow with a pull request number and head commit. Runs authenticate by workload identity federation and spend from the Console organization the four `ANTHROPIC_*` repository variables name; no Anthropic key is stored in GitHub. Each run is capped at 30 assistant turns and a $5 client budget, the owner's per-run spend limit on that organization. This PR and #892 both edit the write-grant inventory and the evidence manifest, so the second to land rebases once. 🤖 Generated with [Claude Code](https://claude.com/claude-code)

…#909) * Add a pre-cue read by Anthropic's pr-review-toolkit agents in Actions claude-pr-toolkit-review.yml runs pr-test-analyzer and silent-failure-hunter from anthropics/claude-code's pr-review-toolkit plugin on one pull request head, through claude-code-action v1.0.247. Both agents list every behaviour and test change the description does not declare, with a confidence on every finding. It is the command center's J8 pre-cue step (W4 draft f), the same agents and settings that found six undeclared changes in #892 and two verifier defects in #900.

Sonnet 5.5 at max effort; Read, Glob, Grep and the Agent tool; CLAUDE_CODE_PRINT_BG_WAIT_CEILING_MS=0 so background agents are awaited; a $5 budget; a review time limit of 20 or 35 minutes by diff size. The bounds step counts the coordinator's own turns only, allows the budget plus a $2 allowance for the agents' last requests, requires both reports, uses an allow-list and names every unmet bound. Dispatch only, owner only, first attempt only, gated by CLAUDE_PR_TOOLKIT_ENABLED; no write scope beyond the OIDC token; nothing is posted to the pull request. 34 tests run the steps as written (without PyYAML too); eight weakened copies each fail them; actionlint and zizmor (pedantic) report nothing. openai/codex-action is recorded as WATCH with its pin and overturn condition. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Publish the toolkit agents' reports from their handbacks when the relay is missing In the local J8 run on #894 the coordinator hit --max-budget-usd 5 (error_max_budget_usd) after both agents had handed back their full reports through SubagentHandback, so it never relayed them and the workflow would have withheld two complete reviews. The numbers and report steps now take the coordinator's relay when it carries both sections, and otherwise assemble the reports from each agent's own SubagentHandback message in the execution file (model-free); with neither, the relay text stays. The usage record says which source was used. All three J8 streams so far carry SubagentHandback calls. Three new tests cover a coordinator that stopped before relaying, a missing handback and a complete relay preferred to the handbacks (37 tests); three mutants of the fallback each fail them; actionlint and zizmor report nothing. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Add the J8-SUMMARY trailer and the sweep fixes to the toolkit read The command center approved a machine-readable trailer for the "defects caught before a cue" ledger: each agent ends its report with one line, J8-SUMMARY {"undeclared": <n>, "confidences": [...]}, so counts come from the agents' own numbers and never from prose. The review itself is unchanged. A test asserts the trailer in the prompt. The sweep of the W4 drafts for the classes #894's pre-cue read found, applied here: the empty paths array is expanded safely on bash before 4.4; a read step that succeeds without an execution file fails the job; display_report and track_progress are asserted; the record states that a public run's summary is public. 39 tests; actionlint and zizmor report nothing. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Bind repository debug settings in the guard and fix the cap notice - R4, from the cc-native-practice lane's L3 read against claude-code-action v1.0.247 practice: the guard binds the ACTIONS_STEP_DEBUG and ACTIONS_RUNNER_DEBUG secrets and variables as booleans, the secret first, and refuses either. A test pins both bindings, and six weakened copies each fail it. - The publish step writes the reports with `jq -j`, so a 60,000-byte report is no longer announced as cut, as the J8 micro read of #892 found for the same step. A boundary test covers it. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Run the toolkit review on Opus with a $22 budget, check every result record and remove links from the head R5, quality and correctness only. The coordinator moves to Opus 5.5 at max with a $22 client budget; the cost bound is the budget times the measured overrun factor 1.10 ($24.20), re-derived after the first three runs. The numbers step reads every result record: each must be a success, or a budget stop after both agents handed back, and a budget stop at or under the bound publishes both reports. Publishing is gated on the numbers step's outcome. The coordinator must call both toolkit agents and no other (retries allowed), replayed on three J8 streams. A tool-list entry that is not a string is a forbidden tool. A model-free step removes symbolic links from the pull request head right after its checkout (GPT designated read of b80a6eb, P2). New tests pin claude_args and --settings exactly; the module goes from 41 to 56 tests. The record names every change and states that the hosted file ends at the first result record, so a run whose agents have not handed back by then fails closed. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Publish only the agents' own handbacks, require both before publishing, and share the cost-factor wording R6. The numbers step fails unless both called agents handed back (a handback counts only under the coordinator's Agent call for that agent, once per agent); relay headings no longer count anywhere (GPT designated read of 7aa2c12, P2). The report step publishes the two handbacks, pr-test-analyzer's then silent-failure-hunter's, and never the coordinator's relay; the coordinator prompt no longer asks for a relay and ends with one line, which saves its output tokens. Publishing is gated on !cancelled() and the numbers step's success, as in the other W4 workflows. The exact --settings pin compares canonical JSON, so 1 or 0 no longer passes for true or false (J8 R5 micro of #894, N1). The record adopts the shared cost-factor paragraph ($22 budget, $24.20 bound) and declares the eight R5 changes the J8 R5 micro read found undeclared. 57 tests; 49 of 49 weakened copies fail a test.

Scope
The R3 descriptive census uses 2018-01-02 through 2023-12-29, 1,509 XNYS sessions. The dated amendment addresses source availability before any count was opened. The previous 2017–2023 window had 1,760 sessions; 2017 returns as R3-F1 only after verified coverage and a publication grant are qualified.
