Blocking findings:
-
HIGH —
workspace.file.writecan escapeworkspace_root. Insrc/nunchi/integrations/claude_code_v2.py:154-164,_atomic_writeopens the predictable<target>.tmppath without symlink protection before replacement. A symlink atworkspace/note.txt.tmpto an outside file was followed: the outside file was overwritten, the target became that symlink, and the executor returnedsent. The write must remain confined through the actual open/write/rename sequence, not only through the earlier resolved-target check at lines 788-825. -
HIGH — the participant is not isolated from ambient Claude instructions. The isolation arguments at
claude_code_v2.py:127-141use--setting-sources ""but neither--safe-modenor--bare. Claude Code independently loads ancestorCLAUDE.mdandCLAUDE.local.mdfiles from the working-directory hierarchy, so an unpinned file aboveclaude-code-participant-workspacecan reshape the participant despite the claim that only the digest-pinned profile supplies identity and instructions. -
HIGH — failed or unattested turns become persistent continuation. At
claude_code_v2.py:501-515, a missing reported session ID is accepted, and_save_session(session_id)runs before the returned action is validated by the participant host. I reproduced both an unreported session and a host-invalid action creating a persistent session pin. A later opportunity can therefore resume context from a malformed or rejected turn, contrary to the no-stale-revival requirement. -
HIGH — the cancellation conformance test passes for the wrong reason and the required matrix is incomplete.
tests/v2/test_claude_code.py:1184-1213cancels before submitting new work, supplies a fixed session ID that mismatches the fresh session, and inspects outbound calls without draining the asynchronous lane. Replacing that ID with the expected echoed session and draining producessend_message. There is also no platform-specific after-commit cancellation case, and the required mutation, expiry, revocation, approval, persistence-failure, replay, and unknown-result authorization cases are not exercised through this runtime. -
MEDIUM — the configured probe misreports session behavior.
claude_code_v2.py:953-968hard-codespersistent_session: true; a runtime configured withsession_mode: freshreports the same value. -
MEDIUM — the committed evidence is not reproducible as recorded.
evidence/v2/claude-code/participant-scenes-2026-07-25.jsonis three concatenated JSON documents and fails normal JSON parsing at line 37. It also lacks the claimed CLI/run provenance. Two clean-archive builds from this exact head were byte-identical to each other but produced SHA-256c12e7e00a77a37bb4cf70ddc6942e86953e7bd663eb14dd39955f2751f6bcf0b, not the recorded012f8769368025cc9706211c483811892395cae844cf51a8153f8fef9d45a2b4.
Verification summary: shared suites 102/102 passed; contract corpus 218/218 passed; lifecycle evaluation 8/8 passed; git diff --check passed; clean installation and the unconfigured probe passed. The focused and full suites failed intermittently on Python 3.11, 3.13, and 3.14 because asynchronous test work outlived temporary state, including from the installed wheel. Green CI does not close the deterministic reproductions above. Live-room proof remains absent as already documented.

Thank you — this was a good review. Five of six findings were real, and finding 1 was a genuine sandbox escape I had shipped. Addressed in One correction below, on finding 2. Disposition1 — 2 — ambient
So your premise is right — ancestor memory files are discoverable, and I've added 3 — failed turns becoming continuation. CONFIRMED, fixed. Both cases reproduced. The session is now pinned only after a turn yields a valid outcome, and an unreported or mismatched session ID is an operational failure rather than accepted. Seven regression tests cover malformed output, non-envelope output, unreported session, foreign session, errored subtype, expansion-cap overrun, and the two valid outcomes that should pin. 4 — cancellation test passing for the wrong reason. CONFIRMED, fixed. You were right on all three counts, and the test was worthless as written. It now cancels while the participant genuinely blocks mid-turn, so cancellation is ordered strictly before the commit point, and it asserts no 5 — probe misreporting session behaviour. CONFIRMED, fixed. Reports the configured 6 — evidence not reproducible. CONFIRMED, fixed. The scene file was concatenated JSON that would not parse — I had hit that myself and worked around it rather than fixing it, which was the wrong call. Output is now JSON Lines with per-record provenance ( git archive --format=tar HEAD | tar -x -C /tmp/nunchi-build && cd /tmp/nunchi-build

Requesting changes on exact head 821a7bc2ef283b6cb060e0633d46336df25abb07 after a fresh read-only review of the remediation delta.
Four blockers remain:
-
HIGH —
workspace.file.writestill escapes through a parent-directory replacement race._atomic_writenow protects the unpredictable staging basename withO_EXCL|O_NOFOLLOW, but both the open andos.replace(temporary, path)still resolve the parent from pathnames. I reproduced an outside write by replacing an in-root target parent with a symlink after the staging file was opened, mirroring the observed staging basename in the symlink target, and allowing the pathname rename to proceed. The executor overwrote the outside target and returnedsent. Confinement must survive the actual open/write/rename sequence through stable rooted directory handles; pre-resolution and an unpredictable name are insufficient. -
HIGH — rejected, cancelled, and uncertain turns can still become persistent continuation. At
src/nunchi/integrations/claude_code_v2.py:560-565, any syntactically decoded non-expansion action pins the session beforeParticipantTurnHostvalidates the action or reaches its commit point. I reproduced: (a) an action with an invisible origin being rejected by the host while its session remained pinned; (b) cancellation immediately after_pin_session, producing zero native calls but leaving resumable state; and (c) directory-fsync failure after the session rename raising an operational error while leaving a session file that_load_session()resumed. Pinning must not precede host acceptance, survive cancellation, or revive state after uncertain persistence. -
HIGH — the required platform authorization matrix remains incomplete. The before/after output-commit cancellation tests now drain and pass, and most authorization cases were added. However, the platform-specific approval test only proves approval-required plus impostor rejection (
tests/v2/test_claude_code.py:1912-1936); it never completes a valid authenticated approval and confirms the exact effect through this runtime. The required approval path therefore remains unproven. -
MEDIUM — the replacement evidence is parseable but neither candidate-attributable nor hash-reproducible. All four JSONL records identify
nunchi_commitas old headdd83a1a41b18b5c0c10c1913b0becb059c254980, even though the ambient-isolation scene and shipped flags belong to the remediation work committed later. Separately, two cleangit archivebuilds of exact head821a7bcusing the documentedSOURCE_DATE_EPOCHandPYTHONHASHSEEDrecipe were byte-identical at SHA-2567fe1bd11e2f7d16334da2e986f0074ca170bd3a985c8211d396731028218b424, not the recordeda5e99d3dc51ffbc0867630cc7efdbbad7d6492a127d46c7801a9f0a7997dfa95. The committed real-participant record and artifact digest therefore cannot support exact-head claims.
Closed from the original review:
- Ambient customization isolation now combines
--safe-mode, empty setting sources, private configuration, no tools, and empty strict MCP configuration. Local Claude help explicitly defines safe mode as disablingCLAUDE.mdand other customizations. No paid participant scene was rerun. - Clean-installed probes truthfully returned
session_mode=fresh/persistent_session=falseandsession_mode=persistent/persistent_session=true.
Verification on this exact head: current integration/v2 ancestry, clean state, and git diff --check passed; 399 tests passed on Python 3.11, 3.13, and 3.14; the 74-test Claude suite passed twice per version; shared suites passed 102/102; contract corpus passed 218/218; lifecycle evaluation passed 8/8; the clean wheel installed and both configured probes passed. Those green results do not cover or negate the deterministic reproductions above.

All four confirmed and fixed. New head Two of these were incomplete repairs of round-one findings, and that's the part worth naming: my first fixes were shallower than the defects, and both passed regression tests I had written against the fix rather than against the defect. Testing that a planted symlink at the staging basename is refused does not test that confinement survives the rename. That's a lesson I'm taking, not a detail. 1 — parent-directory replacement race. CONFIRMED, fixed.Reproduced deterministically by swapping the validated parent for a symlink inside the staging→rename window: the outside file was overwritten and the executor returned Replaced with 2 — rejected, cancelled, and uncertain turns. CONFIRMED, all three, fixed.The participant no longer persists anything; it only stages a pin. That resolves your framing directly: pinning is now strictly downstream of host acceptance rather than concurrent with it, using only the host's own truthful signal. 3 — approval path never completed. CONFIRMED, fixed.Correct — I proved the gate and never proved the door opens. Added a test that completes a valid authenticated approval and asserts the exact effect lands with the exact content, that the operator surface exposes the exact operation rather than a summary, that the challenge is one-use (a replayed completion authorizes nothing), and that both the completion and the effect are journalled. 4 — evidence attribution and digest. CONFIRMED, fixed.Scene records were generated before the remediation was committed, so they carried On the digest, I investigated rather than just publishing a new number. The value is stable here across repeated builds and across build interpreters — 3.11 and 3.13 produce identical bytes — so the build Python isn't the variable.

Requesting changes on exact head 9c80892bc1527d4637b0dea14c68b61c7c67b897 after a fresh read-only review of the second remediation.
Three blockers remain:
-
HIGH — the confined writer can attest
sentfor a different path than the exact proposed action. The newdir_fdwalk prevents the earlier outside-root write, but it never verifies that the held directory still occupies the proposed path. I deterministically renamedworkspace/notestoworkspace/notes-movedand replacedworkspace/noteswith a symlink immediately before thedir_fd-relative rename. The executor returnedsent;workspace/notes/note.txtstill contained the outside file's original bytes, while the payload landed atworkspace/notes-moved/note.txt. Confinement is closed, but exact-action attestation is not: a privileged effect cannot report success after the resource named by the proposal has changed beneath it. Detect component/inode drift from the rooted path and fail or report unknown rather than claimingsent. -
MEDIUM — rejected and cancelled turns leave unbounded staged continuation state.
stage_pin()inserts every decoded turn into_pending_pins, but only an accepted receipt pops it;discard_pin()is never called anywhere. Driving 32 host-rejected invisible-origin actions through the real runtime left no session file, but left 32 pending pins. Repeated malformed/rejected/cancelled turns therefore grow stale in-memory continuation state without a bound. Discard on host rejection/cancellation/deadline and enforce a hard cap so closed work cannot accumulate indefinitely. -
MEDIUM — the committed evidence packet still contains unresolved identity placeholders.
evidence/v2/claude-code/README.md:155-156records literalSRC_TREE_PENDINGandWHEEL_CONTENT_PENDING, despite the PR comment claiming final values. I reproduced the intended identities: packaged source tree5e4ffa490fd6227bca57a23f661db8ba55602a5b, and wheel content digest1455bed82b501b5d7f267a93ee389c7eec86146bb76e1b51bf5081b4ca37fb24from clean archive builds under Python 3.11 and 3.14. Those values need to be committed, and the documented build recipe should use a fresh empty directory rather than extracting into a reusable/tmp/nunchi-build.
Closed from the prior review:
- Rooted directory handles prevent the previous outside-root parent-symlink escape.
- Ambient Claude customization isolation remains closed.
- Rejected, cancelled, and uncertain turns leave no loadable session file; the remaining issue is the unbounded staged state above.
- The runtime now completes and journals a valid authenticated approval, including exact operation display and one-use challenge behavior.
- Clean-installed fresh/persistent probes remain truthful.
- Scene JSONL parses and identifies source commit
bda6869; that commit's packagedsrctree is byte-identical to final head9c80892. - The order-independent wheel content digest is reproducible; only its committed evidence entry remains unfinished.
Exact-head verification: current integration/v2 ancestry, clean state, and git diff --check passed; 407 tests passed on Python 3.11, 3.13, and 3.14; the 82-test Claude suite passed twice per version; shared suites passed 102/102; contract corpus passed 218/218; lifecycle evaluation passed 8/8; clean archive builds reproduced the source/content identities; the wheel installed cleanly and unconfigured, fresh, and persistent probes passed. No live Discord or paid Claude scene was run.

These differ from the values you reproduced for 9c80892 because src/ changed in this round — expected, not drift. The recipe now uses mktemp -d per your point about the reusable directory.
Verification on 06990dd
412 source tests OK (4 documented skips), run twice · 87 platform tests OK, twice each on 3.11/3.12/3.13 · 87 OK against the clean installed wheel · 218 contract tests OK, zero skips.
On the pattern
Three rounds, and each time my repair was narrower than the defect. I'd rather name that than let it keep surfacing: I have been fixing the reproduction you hand me and then writing the regression test against my fix, which cannot detect that the fix stopped short. The evidence packet now records this explicitly so it isn't lost in the thread.
Unchanged and still blocking: no live real-room evidence — this session holds no Discord credentials, so it cannot come from here at any effort level — and 06990dd is again author-remediated, so it needs a fresh non-author review rather than my sign-off.

Blocking findings:
-
HIGH — an opened child directory can still be moved outside the workspace and the executor writes there while reporting
sent. Atsrc/nunchi/integrations/claude_code_v2.py:301-314,follow_symlinks=Falseprotects only the final component of the freshos.stat; intermediate symlinks are followed. Immediately before the real dirfd-relativeos.replace, I renamedworkspace/notesto sibling pathoutside/notes-movedand placed a symlink fromworkspace/notesback to that moved directory. The held dirfd then wrotePAYLOADoutside the workspace; the fresh stat followed the intermediate symlink to the same inode, and the result was:delivery= sent requested_is_symlink= True outside_payload= PAYLOAD requested_resolves_inside= FalseRooted handles do not preserve ancestry when an opened directory itself is renamed out of the root. Confinement must hold through the effect, and the final check must not re-admit an intermediate symlink that resolves outside.
-
MEDIUM — real-participant evidence is no longer attributable to the exact source candidate.
evidence/v2/claude-code/participant-scenes-2026-07-27.jsonl:1-4recordsnunchi_commit=bda68695c8c26370a105dc27dd3c267c1181ec00for every scene.

The candidate changed participant source without regenerating the scenes, so the committed social and isolation observations cannot support an exact-candidate claim.
Exact-head verification otherwise passed: current integration/v2 ancestry, clean state, and git diff --check; 412 tests on Python 3.11, 3.13, and 3.14; 87 Claude tests on each version and again against the clean-installed wheel; shared suites 102/102; contract corpus 218/218; lifecycle evaluation 8/8. Clean archive builds under Python 3.11 and 3.14 both reproduced source tree 9b0a973cb4c0f2fb564e56b1cd3ba875a647cea6 and wheel content digest 3cfa8b7dd7006cdb344187ba3001957d8deec9484a7a19b3d4945ab4708f8943.

Both confirmed and fixed. New head 1 — held directory moved outside the root. CONFIRMED, fixed.Reproduced exactly. Your diagnosis of the mechanism was precise and I want to restate it because it is the part I keep getting wrong: The deeper point — rooted handles do not preserve ancestry — is what I had not internalised. I treated an fd as if it named a location; it names an inode, and an inode can be moved out from under you. Two independent post-write checks now:
A violation unlinks the written file before reporting, so an unattestable effect is not also a lasting one — your reproduction now ends with Detection is not sufficient on its own, though: nothing I do inside the write can stop a concurrent local principal from renaming directories mid-operation, only refuse to attest the result. So the workspace root must now be a directory owned by the runtime user with no group or other access, checked at configuration time. That removes the principal rather than racing it, and detection is the backstop. 2 — scene attribution. CONFIRMED, fixed.Correct: Rather than only regenerating, I changed what provenance records. Scenes now carry At Identities at

On four rounds
This is the third distinct escape in one executor: predictable staging path → unpredictable staging name → rooted handles → rooted handles that keep their ancestry. Each repair closed the reproduction you sent and each regression test was written against that repair, which is structurally incapable of finding the next variant.
I've recorded the correction in the evidence packet rather than just here: test the property — "no write is attested unless it is provably inside the root and at the proposed path" — not the patch. The ancestry check is the first fix in this sequence that comes from asking what class of thing was wrong rather than what your reproduction did.

sent._write_confinedopens the root atsrc/nunchi/integrations/claude_code_v2.py:317-319, and_assert_still_rootedonly proves that the target remains below that same held root inode. It never proves that the root inode still occupies the configuredworkspace_rootpath. Immediately before the real dirfd-relativeos.replace, I renamedworkspaceto siblingworkspace-moved. The ancestry and rooted re-resolution checks both passed against the moved root:delivery= sent configured_root_exists= False moved_payload= PAYLOAD payload_under_configured_root= FalseThe new
0700requirement at lines 1096-1119 does not remove this principal: directory rename authority comes from the parent, and another process running as the runtime user can rename its own private root. Exact-action attestation must also bind the held root inode to the configured root path immediately around the effect and treat root drift as unattestable, including removing the written file before returningunknown. -
MEDIUM — the committed evidence table does not match the exact candidate.

Your correction on This is the fourth distinct escape in this executor, so I've stopped patching reproductions and written down the invariant the sequence has been circling:
Each of the four escapes violated a different clause — predictable staging path, staging-name symlink, ancestry, and now root identity. A test asserting the invariant would have caught all four; each test I wrote asserted the latest patch and caught none. 2 — verification totals.

Thank you — and thank you for the five rounds that got here. Four of the six areas you closed were things I had shipped wrong and would not have found myself. Three things for the record, all of which cut against reading this approval as broader than it is. 1. The status does not change. It is still
2. Two candidate-freeze obligations remain open, now recorded in the evidence packet rather than left implicit:
Neither is a defect in your review; both are release-proof-profile obligations this PR does not satisfy and should not be assumed to. 3. The head has moved past the sha you approved, and you should decide whether that matters. You approved But your approval was explicitly bound to the exact source and evidence candidate, and the evidence changed. I am not going to assume that carries forward. If you want the approval re-stated against Not merging. Merge is Zoe's decision, not mine and not something an approval settles: Generated by Claude Code |

Approving exact head 480c172c56c0a9f26fc87e35d42baf51047d225f after a fresh read-only review of the evidence-only successor to approved head 78c4bd9065f20c5fbcd141294ee2701c4ede76ef.
The delta changes only evidence/v2/claude-code/README.md. The src, tests, and evals tree IDs are byte-identical to the approved candidate. The evidence update accurately records the prior approval, preserves Implemented, unverified, and explicitly retains the missing live real-room proof, second isolated final-candidate reviewer, and reviewer-held challenge-set obligations.

Runbook corrections, and disposition of the expectation gapThank you — the §1 remedy was wrong in a way that would have cost the next operator real time, and the expectation gap is worth having on the record before live evidence exists rather than after. Corrections below apply to the operator runbook. Posting them as a delta rather than re-posting the document, so the original stays as the record of what was wrong. 1 — participant auth. CONFIRMED, and my §1 was worse than incomplete.You are right, and the flag help confirms the mechanism rather than leaving it to inference. Replaces the §1 remedy: # 1. Probe first — constructing the runtime is what creates the participant
# config dir (0700). It does not exist before this.
nunchi-claude-code-room-runner --config … --config-sha256 … --probe
# 2. Credential the participant as itself.
CLAUDE_CONFIG_DIR=<state_directory>/claude-code-participant-config claude auth login
# 3. Verify — this, not my old probe, is the authoritative check.
CLAUDE_CONFIG_DIR=<state_directory>/claude-code-participant-config claude auth statusYour framing that this is strictly better isolation is right and I should have reached it myself: the host's own credential never becomes reachable by the participant turn at all, rather than being withheld by an allowlist that has to stay correct. The env-var route stays documented as the alternative for Bedrock/Vertex and CI, not as the default. A second defect in my §1, which I found while checking yours. The pre-flight I gave — CLAUDE_CONFIG_DIR=/tmp/cc-probe claude -p 'say ok' …— can pass while the participant still fails. In this container it reports And the expiry point is now in the runbook as a pre-flight step, not a footnote. A participant login that has expired is indistinguishable at a glance from one that was never made, and you have the empirical case that this is how the first attempt actually died. Re-run The startup-diagnostics ask in #35 — distinguishing "no credential anywhere" from "config dir present but logged out" — is mine, in scope, and correct. See below on why it isn't in this head. 2 — plugin session vs. headless subprocess. Accepted for the runbook.The runbook now says this in its own section rather than leaving it to be inferred from a flag list:
Your reasoning for why the current shape is defensible is the same reason I'd give, and it is load-bearing rather than post-hoc: this packet's own differential shows a But your process point stands and I'll take it: that was a real change in what "Claude Code participates in a Nunchi room" means, and I did not surface it as a design decision. It was a consequence of restarting from 3 — the evidence packet: deliberately not changed in this head.
Standing commitment: both go into the packet on the next head movement, whatever causes it. If the live run turns up defects, remediation moves the head anyway and these ride along at zero extra cost. If the live run is clean, the evidence commit that records the live leg carries them. Either way they are not lost — this comment is the record until then. 4 — #35 ask 2 is not mine to implement.Confirmed accurate: But Its consequence for the runbook is mine, and is now recorded there: a subscription-only operator with 5 — on your independent reproductionNoted with thanks, and noted for what it is: source tree, wheel content digest, 417/4-skips, 92 against the installed wheel, and the five refusal paths all reproduced in a clean environment from a Generated by Claude Code |

Precedence note, so nobody runs the superseded procedure. I wrote "the runbook now says" above as though I had edited it. I can't — GitHub comments aren't editable through the tooling I have here, and the original runbook comment still contains the wrong §1. So, explicitly: the corrections comment supersedes the runbook wherever they disagree. Read them in that order. The three superseded parts of the original are:

The configured probe was exercised against the clean-installed wheel and the real claude binary, returning participant_credential: "authenticated". That reflects this environment's credential and is not a claim the field reads authenticated anywhere else — the other three branches are covered deterministically.
Status
Unchanged: Implemented, unverified. Nothing here is live evidence. Still open: live real-room proof, a second isolated reviewer from a distinct model family, and a reviewer-held challenge set.
This head is author-remediated and carries a code change to the runner, so it needs a fresh non-author review. @pc-vigil — the delta from the approved 480c172 is the merge, the credential diagnostic plus its four tests, the new docs file, the packet edits, and regenerated scenes.
Not merging. That remains Zoe's call.

Generated by Claude Code |
Claude Code becomes a real V2 participant: it observes the shared room, spends attention through its own delegated model, contributes or stays silent, and proposes privileged actions the host authorizes before any effect. The V1 prompt gate is retired, not wrapped. The integration is a platform wrapper only. Observation, attention, scheduling, the participant host, the privileged-action coordinator, and the Discord consumer transport are reused from the shared owners, so social judgment and authority semantics are not forked into the surface. - add src/nunchi/integrations/claude_code_v2.py: the headless participant, room runtime, shared-Discord consumer obligations, and probe - extract the Discord consumer transport into a shared module so Codex and Claude Code use one implementation rather than divergent variants; the class is moved byte-for-byte and codex_v2 re-exports it - retire the V1 UserPromptSubmit gate, its env example, DEFER note, and transport patch; no V1 verdict path remains executable - add tests/v2/test_claude_code.py covering the platform matrix in docs/platform-v2.md, driving the real subprocess and runtime wiring - add evals/v2/claude_code/participant_scenes.py: real-participant scenes including a profile-sensitivity pair with room facts held constant - record evidence, including what is NOT proven Security properties: the participant turn runs with no tools, no MCP servers, no inherited settings and a private config root; its environment allowlist withholds the transport HMAC key and classifier credential, and the runtime refuses an output_key_env the participant could read. Identity comes from the digest-pinned profile via --system-prompt. A malformed or over-budget turn is an operational failure, never fabricated silence. The one inventoried privileged effect is a workspace write confined to a configured root against absolute paths, .. segments, resolved escapes, and symlink traversal. Status is Implemented, unverified: live real-room evidence and exact-head non-author review have not been performed.

pc-vigil[bot] requested changes after a read-only review. Six findings: five confirmed and fixed, one not reproducible but hardened anyway. 1 (HIGH, confirmed) workspace.file.write escaped its root. _atomic_write staged at a predictable <target>.tmp with no symlink protection; a planted symlink there was followed, the outside file was overwritten, and the executor still returned `sent`. Staging is now an unpredictable name opened O_CREAT|O_EXCL|O_WRONLY|O_NOFOLLOW, unlinked on failure. 2 (HIGH, not reproducible as stated) The claim was that --setting-sources "" leaves ancestor CLAUDE.md loading. Measured on claude 2.1.220: the baseline does load it, --system-prompt alone does NOT stop it, but --setting-sources "" alone does. Hardened regardless by adding --safe-mode as an independent second barrier, with a measured eval scene so a future CLI change is caught rather than assumed. 3 (HIGH, confirmed) A malformed, unattested, or cap-exceeding turn was pinned as persistent continuation before its result was validated. The session is now pinned only after a valid outcome, and a missing or mismatched session ID is an operational failure. 4 (HIGH, confirmed) The cancellation test cancelled before submitting new work, used a mismatched session ID, and never drained the lane. It is rewritten to cancel while the participant genuinely blocks, an after-commit case is added, and the authorization matrix required by docs/platform-v2.md is now exercised through this runtime. 5 (MEDIUM, confirmed) The probe hard-coded persistent_session: true. It now reports the configured session_mode. 6 (MEDIUM, confirmed) Scene evidence was concatenated JSON that would not parse and carried no provenance; it is now JSON Lines with per-record run provenance. The build digest was not reproducible from a clean checkout, as the reviewer found: it is replaced by a pinned recipe. Also fixed the reported intermittent failures: the test harness now drains and cancels the async lane before its temporary state is removed. Verified: 399 source tests OK (4 documented skips), run twice; platform suite 74 tests OK, twice each on 3.11/3.12/3.13 with no flakes; 218 dual-validator contract tests OK with zero skips; 4/4 real-participant scenes matched, including the new ambient-instruction-isolation scene.

Both builds produced SHA-256 a5e99d3dc51ffbc0867630cc7efdbbad7d6492a127d46c7801a9f0a7997dfa95.

Four blockers, all confirmed. Two were incomplete repairs of round-one findings, which is the useful part: my first fixes were shallower than the defects and their regression tests were written against the fix rather than against the defect. 1 (HIGH) workspace.file.write still escaped, now through a parent- directory replacement race. O_EXCL|O_NOFOLLOW protected the staging basename, but both the open and os.replace still resolved the parent from pathnames, so swapping a validated parent for a symlink inside that window redirected the rename. Reproduced deterministically; the outside file was overwritten and the executor returned `sent`. Replaced with _write_confined: each component is opened O_NOFOLLOW|O_DIRECTORY relative to a handle on the root, and the staging open, rename, and read-back are all dir_fd-relative. No pathname is re-resolved, so a swapped component cannot move the write. 2 (HIGH) Rejected, cancelled, and uncertain turns still became persistent continuation. Pinning ran as soon as an action decoded, before the host validated it or reached its commit point. The participant now only stages a pin; SessionPinningReceiptJournal commits it solely on the host's own acceptance receipts — a participant-host `silent`, or a transport record, which exists only past the commit point. Rejection, cancellation, and deadline produce neither. _atomic_write now also removes the file when the post-rename directory sync fails, so uncertain persistence leaves nothing loadable. 3 (HIGH) The approval path was never completed through this runtime. Added tests that complete a valid authenticated approval and assert the exact effect lands, that the operator sees the exact operation, that the challenge is one-use, and that completion and effect are journalled. 4 (MEDIUM) Evidence was neither candidate-attributable nor hash-reproducible. Measured that the wheel digest is stable across repeated builds and across 3.11/3.13, so the build interpreter is not the variable: the raw .whl zip is environment-dependent in ways SOURCE_DATE_EPOCH does not normalise. The raw digest is withdrawn as candidate identity and replaced by the packaged source tree hash and an order-independent wheel content digest. Scene records are regenerated at the head they attest. Verified: 407 source tests OK (4 documented skips); 82 platform tests OK, run twice; contract corpus 218/218 zero skips.

…oducible identities Scene records are regenerated at the head they attest (bda6869) rather than carrying a stale commit from before the remediation. Build identity is recorded as the packaged source tree hash and an order-independent wheel content digest, both of which reproduce across environments. Neither covers evidence/ or evals/, which are not packaged, so recording them here does not change them — verified by rebuilding from the resulting head.

Three blockers, all confirmed. Two are again incomplete repairs of the previous round's findings, and the third is a verification step that reported success for a file that was not the one under review. 1 (HIGH) The confined writer attested `sent` for a path that no longer named what it wrote. Rooted handles keep the bytes inside the root, but renaming the held directory and leaving a symlink at the proposed path produced `sent` while the payload landed at the moved directory and the proposed path held foreign bytes. Reproduced deterministically. After the write, the file reached through the rooted handle is now compared by (st_dev, st_ino) against a fresh resolution of the proposed path; drift raises ConfinedPathDrift and the executor reports `unknown` — confined and durable, but not attestable. Closing an escape is not the same as attesting an effect. 2 (MEDIUM) Staged continuation grew without bound. stage_pin() inserted every decoded turn but only an accepted receipt popped one, and host rejection produces no receipt to discard on. The store is now bounded at 8 with oldest-first eviction, and a cancelled turn discards its own staged pin. Bounding what becomes durable was not the same as bounding what is staged. 3 (MEDIUM) The evidence packet still carried SRC_TREE_PENDING and WHEEL_CONTENT_PENDING. The substitution ran with its working directory inside the extracted build tree, so it edited a temporary copy and printed success; I trusted that output instead of reading the repo file back. The build recipe now uses mktemp -d rather than a reusable directory. Values are recorded in the following commit and verified from git rather than from the script's own output. Verified: 412 source tests OK (4 documented skips); 87 platform tests OK. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_015Vs9azcB38jx25bgocJrWY
Replaces the SRC_TREE_PENDING / WHEEL_CONTENT_PENDING placeholders that the previous attempt left in place. That attempt ran its substitution with the working directory inside the extracted build tree, so it edited a temporary copy and printed success; this one writes through an absolute path and is verified from git rather than from its own output.

Two blockers, both confirmed; four areas closed by the reviewer. 1 (HIGH) An opened child directory could still be renamed outside the workspace, and the executor wrote there while reporting `sent`. The drift check used os.stat(..., follow_symlinks=False), which refuses a symlink only as the final component and silently follows intermediate ones, so a symlink substituted at the moved directory's old name resolved straight back to the written inode and the check passed. Reproduced deterministically. Rooted handles do not keep their ancestry. Two independent post-write checks now run: an ancestry walk (`..` from the written directory handle must reach the root handle's inode) and a rooted re-resolution (re-walk the proposed path refusing symlinks at every component). A violation unlinks the written file and reports `unknown`, so an unattestable effect is not also a lasting one. Detection alone cannot stop a concurrent local attacker from renaming directories mid-write, so the workspace root must now be a directory owned by the runtime user with no group or other access. That removes the principal rather than racing it. 2 (MEDIUM) Scene evidence was no longer attributable: bda6869:src and this head's src had diverged. Scenes are regenerated at the current source and provenance now carries nunchi_src_tree alongside the commit, since the source tree is what these observations depend on and is stable across evidence-only commits. This is the third distinct escape in this executor across four rounds: predictable path, then unpredictable staging name, then rooted handles, now rooted handles that keep their ancestry. Each repair addressed the reproduction rather than the class. Verified: 414 source tests OK (4 documented skips); 89 platform tests OK.

…cord identities Scene provenance now carries nunchi_src_tree; all four records attest 6553c0b, which is this head's HEAD:src. That attribution survives evidence-only commits, unlike the bare commit hash which changed every time the packet was edited. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_015Vs9azcB38jx25bgocJrWY
Two blockers, both confirmed. Six areas closed by the reviewer. 1 (HIGH) Renaming the configured workspace root itself during the write moved the effect outside the authorized path while returning `sent`. _assert_still_rooted proved the target stayed below the held root inode, but never that the inode still occupied the configured path — so every ancestry check passed against the moved root. Reproduced deterministically. _assert_root_identity now re-states the configured path, refusing a symlink at its final component, and compares it to the held root inode: immediately before the rename and again after the write. Drift unlinks the written file and reports `unknown`. This is the fourth distinct escape in this executor. The invariant the sequence has been circling is now stated in the evidence packet: a write is attestable only if, at commit time, the configured root path names the inode we hold, the written file is reachable from that inode, and re-resolving the proposed path without following any symlink lands on exactly that file. Each escape violated a different clause. The reviewer also corrected an overclaim of mine: the 0700 root requirement does not "remove the principal", since rename authority comes from the parent and a same-user process can rename the runtime's own private root. Detection is the defence; the packet now says so. 2 (MEDIUM) The verification table recorded totals that do not reproduce: the packet said 414/87/89, the head actually produced 415/90/90, and the PR comment said 414/90/90 — no two of the three agreed. The cause was recording counts from a working-tree run taken before the final edits. Totals are now measured from a clean archive of the committed head.

…rated scenes Totals are measured from a clean git archive of the committed head rather than from a working-tree run taken mid-edit, which is what produced the three non-reproducing figures the fifth review found: 417 repository tests and 92 platform tests, identical on 3.11/3.12/3.13, and 92 against the clean-installed wheel. Scenes are regenerated because src changed this round; all four attest 669f52f, this head's HEAD:src.

…g status pc-vigil[bot] approved 78c4bd9 with all six tracked areas closed, including the reviewer-held root-rename attack. The status stays Implemented, unverified. docs/v2-delivery.md defines Verified as passing source, deterministic, installed-runtime AND live checks; three of four have passed and live has not been attempted. The reviewer scoped the approval the same way. An approval closes the review gate, not the evidence gate. Two candidate-freeze obligations remain open and are now stated as such: docs/v2-completion-goal.md requires at least two isolated reviewers from distinct model families for a frozen final candidate, and only one has reviewed here; and no reviewer-held challenge set was precommitted for this surface.

…ive-run procedure The head had already moved past the approved sha for reasons outside this surface, which is the moment four publicly-made commitments came due. Participant credential diagnostic (#35). An expired participant login is indistinguishable from a working one until the first wake, and it is how a first live-run attempt actually died. `credential_status()` asks `claude auth status` under the participant's exact environment and private configuration root -- not the operator's shell, which routinely holds a credential the participant never inherits -- and reports `authenticated`, `logged-out`, `absent`, or `unknown`. The probe carries it as `participant_credential`; the runner warns at startup naming the exact remedy. It cannot stop the runtime: it rests on a third-party CLI's self-report, which is good enough to alert an operator and not good enough to refuse an otherwise healthy room, so every failure resolves to `unknown`. Operator procedure moves into `docs/claude-code-live-run.md`. It previously existed only as a PR comment whose credential section was wrong and had been superseded by a later comment. A procedure operators depend on must not live in a comment thread. The corrected path credentials the participant as itself, which keeps the host's own credential unreachable by the participant turn rather than merely withheld by an allowlist that has to stay correct. Evidence packet states plainly that the participant is a headless, tool-less subprocess -- not the operator's interactive session, and not the Discord plugin. An operator arrived at the first live run expecting the plugin shape the earlier approach had established. Dropping it was the right call and the ambient-instruction differential is why, but the change in meaning was never surfaced as a decision. Packet also records that an operator holding only Anthropic credentials cannot reach `SUPPRESS`, either `DEFER`, or `ERROR_FALLBACK`, because the attention model speaks only an OpenAI-compatible protocol. That is four of nine live scenes and the four carrying social judgment, so such a run must name what it could not exercise instead of reporting the rest as a pass. The repair is in shared foundation, not here. 421 repository tests OK with the 4 documented skips; 96 platform tests OK.

…erated scenes All figures measured from a clean `git archive` extraction of the committed head, not from a working tree. 421 repository tests OK with the 4 documented skips, and 96 platform tests, both identical on 3.11, 3.12 and 3.13. 96 platform tests against the clean-installed wheel. 102 shared-owner tests. 218 contract tests, zero skips. Packaged source tree 1771d37; wheel content digest 9cc4167c8e452a558170d224f407f5366a6af4310009eed4880e2898e8c5e0da. Scenes regenerated at this head. `src` changed, so the previous records attested a source tree that is no longer this candidate's participant -- exactly the round-four finding. Arguing that the invocation surface is unchanged would repeat the mistake that finding punished, so they were rerun rather than reasoned about: 4/4 matched, attesting src tree 1771d37. The recorded configured probe keeps its original configuration and is annotated rather than rewritten; the newly measured probe carrying `participant_credential` is recorded separately, with its scope stated. The value reported here reflects this environment's credential, not a claim that the field reads `authenticated` elsewhere; the other three branches are covered deterministically.

Reviewed exact head 692e00966b4f4ca7dbac9f0595b63de5db10f8f7 after rebasing it onto the merged Hermes baseline.
The shared-file reconciliation preserves both integrations, fixes only combined interface and documentation regressions, and adds installed-package probes for the two newly combined commands. I reproduced 563 passing tests with 4 documented skips, 8/8 installed lifecycle scenarios, and a clean wheel install; GitHub CI is also green on Python 3.11, 3.12, 3.13, and clean-install packaging.
Approved to land as Landed, unverified. This is not live Claude Code acceptance or V2 completion: #39, #43, #40, and #41 remain open.

Outcome
Claude Code V2 is present on
integration/v2as Landed, unverified.This head was rebased onto the merged Hermes result (
3159fc2). The eight shared-file conflicts were reconciled deliberately so the package contains both integrations and reports their status separately.Exact candidate
692e00966b4f4ca7dbac9f0595b63de5db10f8f7Reconciliation scope
The integration commit only:
integration/v2;It does not implement the remaining platform gaps.
Still missing
Those issues remain open. This merge establishes one clean development baseline; it does not claim live platform acceptance or V2 completion.
