Summary

Add the finite claude-sonnet-5-5 profile to the existing three-flow runner, admission, accounting and exports.

• Use between_tools, low effort, and automatic tool selection with parallel tool calls disabled.
• Send the complete canonical current Core snapshot and current request digest on each fresh stateless request. No native thinking replay, prompt trimming or compaction.
• Preserve earlier rosters, evidence readers, grades, Core, evaluator and cases. No dependency changes.
• Reject unsupported November pacing during admission instead of silently changing transport policy.
• Initialize the November mode flag in the existing legacy HTTP test fixture; preserve every prior assertion and production byte.

Verification and execution

• Current candidate: 3e85af7be28c6869ef9b87eecd0b8adcc87ca2eb.
• Final test-only delta: one added fixture initialization; production runtime is byte-identical to 213d672ddaa8ec296c6b0bbe7b9c8e01785e020e.
• Clean-source focused HTTP, November and selected-six regressions: 118 passed, no skips.
• Earlier whole-feature focused qualification: 136 passed, 2 skipped; Ruff, formatting, mypy and publication scans passed at the evaluated production revision.
• Two actual Sonnet observations of the same 44 cases completed at evaluated revision 213d672ddaa8ec296c6b0bbe7b9c8e01785e020e: all 88 case observations audited with offline replay, complete usage and no technical exclusions or aborts. Historical grades remain unchanged.
• Separate synthetic SDK qualification and standalone live diagnostics are not model-quality observations and are not included in the public aggregates.
• Real aggregates are prepared in a separate website change; no raw traces or private evidence are published by this PR.

Remaining gates

• Required full hosted CI/build and completed current-head Qodo review before merge.
• Separate website review, CI, deployment and live artifact verification.

Only Sonnet is added. Other proposed models remain blocked on confirmed account-route access and are not silently substituted.

1. November requests lose requested pacing ✓ Resolved

Resolving commit: 213d672

Resolution reason

The commit changes the November branch of registry() so it only accepts transport_policy ==
"legacy-v1" and raises "November requires legacy-v1 transport policy" for any other value, including
paced-safe-errors-v1. Admissions requesting pacing are now rejected during validation instead of
silently running unpaced. Tests were added to confirm legacy-v1 is accepted and paced policy is
rejected, both at registry level and at the admission/CLI level.

Description

The November branch of registry() accepts paced-safe-errors-v1, but the live transport factory
passes legacy-v1 for Anthropic. An admission requesting pacing therefore validates and runs, while
the transport installs no pacer and records no paced-policy setting.

1. Cleanup can delete replacement 🐞 Bug ☼ Reliability

Description

_cleanup_created_inode checks the basename's inode and then unlinks that mutable name in a
separate operation, so a concurrent rename between the check and os.unlink causes cleanup to
delete a replacement inode. This can destroy another process's completed file while handling an
unrelated write or identity failure.

Code

src/operatebench/_write_once.py[R170-173]

+    if named is None or not _same_inode(named, created):
+        return
+    try:
+        os.unlink(name, dir_fd=dirfd)

Relevance

●●● Strong

Specific concurrent replacement race undermines the PR’s stated cleanup safety guarantee; no
rejection precedent found.

ⓘ Recommendations generated based on similar findings in past PRs

Evidence

The helper first obtains and compares the currently named inode, then separately unlinks by
basename. Cleanup is called from multiple failure paths, while the existing replacement test only
swaps the name before cleanup begins and therefore does not cover the check/unlink seam.

## Issue description
Cleanup performs a check-then-unlink on a mutable directory entry, allowing a replacement inode to be deleted after identity verification.

2. Close failures report success 🐞 Bug ☼ Reliability

Description

The final file descriptor is closed under suppress(OSError), so a close-time I/O error is
discarded and _write_once_bytes returns success. That violates the primitive's durable-write
contract and regresses the prior context-manager implementation, which propagated close errors
through its except OSError path.

Code

src/operatebench/_write_once.py[R271-273]

+        if descriptor_to_close is not None:
+            with suppress(OSError):
+                os.close(descriptor_to_close)

Relevance

●●● Strong

Close-time I/O errors violate the stated durable-write contract and prior error-propagation
behavior; no rejection precedent found.

ⓘ Recommendations generated based on similar findings in past PRs

Evidence

The new helper promises durable creation, but its only final-file close is wrapped in
suppress(OSError) immediately before returning. The replaced implementation used `with
os.fdopen(...) inside an except OSError` block, so errors raised while exiting and closing the
handle were translated rather than ignored.

## Issue description
The writer suppresses final-file close errors and can return success despite an I/O failure.

1. Malformed paths leak descriptors 🐞 Bug ☼ Reliability

Description

When a parent component contains an embedded NUL, os.open raises ValueError, but
_open_parent_chain catches only OSError and exits without closing the descriptors already
accumulated. Repeated malformed writes can exhaust the process descriptor table, and the error also
bypasses the intended domain-error translation.

Code

src/operatebench/_write_once.py[R73-74]

+        except OSError as exc:

Relevance

●●● Strong

Exception cleanup gap is a deterministic reliability bug with a straightforward local fix.

ⓘ Recommendations generated based on similar findings in past PRs

Evidence

The writer opens the anchor before walking components, accumulates each successful descriptor, and
only invokes _close_all from its OSError branches. An embedded-NUL component causes the standard
os.open API to raise ValueError, so control bypasses those branches before _open_parent_chain
returns to the outer cleanup; write_artifact publicly accepts caller-provided paths and relies
entirely on this primitive.

2. Ancestor walk exhausts descriptors 🐞 Bug ☼ Reliability

Description

_open_parent_chain retains one open descriptor for every ancestor until the complete write
finishes, so sufficiently deep valid output paths or concurrent writes can hit the process
descriptor limit and fail despite the filesystem path being writable. This also makes descriptor
consumption scale as path depth multiplied by concurrent writers.

Code

src/operatebench/_write_once.py[R70-73]

+    for component in absolute.parent.parts[1:]:
+        parentfd = descriptors[-1]
+        try:
+            childfd = os.open(component, directory_flags, dir_fd=parentfd)

Relevance

●● Moderate

No close historical precedent; resource-scaling concern is plausible but remediation design is
subjective.

ⓘ Recommendations generated based on similar findings in past PRs

Evidence

The implementation starts with an anchor descriptor, appends a new descriptor for every parent
component without closing any prior one, and closes the list only after creation, writing, both
fsyncs, and namespace verification. The public CLI accepts an arbitrary output path, so path depth
directly controls transient descriptor consumption.

## Issue description
The parent walk keeps every ancestor descriptor open, making valid writes fail with descriptor exhaustion on deep paths or under concurrency.

## Issue Context
Preserve the security properties without retaining the full descriptor chain: record each opened directory's `(st_dev, st_ino)` identity, close ancestors once the next child is securely open, retain only the final parent needed for creation, and make the namespace rewalk compare against recorded identities. Add a deep-path regression under a reduced descriptor limit where supported.

1. Tests require Linux procfs 🐞 Bug ⚙ Maintainability

Description

The new descriptor-leak assertions directly enumerate /proc/self/fd, which does not exist on

1. Ancestor symlink passes final check 🐞 Bug ⛨ Security

Description

After the no-follow namespace rewalk finishes, the final os.stat(..., follow_symlinks=False) still
follows symlinks in ancestor components. An attacker can rename an ancestor and symlink its old name
to the renamed original tree, making the stat observe the same created inode and return success even
though the artifact path now violates the real-directory-only contract.

Evidence

The no-follow helper validates and then closes the parent chain before the changed full-path stat
runs. That stat only checks the final component and the subsequent comparison checks type and inode,
so a symlink to the relocated validated tree preserves both; this contradicts the artifact adapter's
explicit real-directory-only contract, while the current adversarial test uses a different attacker
inode and misses this same-inode variant.

## Issue description
The final full-path stat follows ancestor symlinks, so an ancestor replaced with a symlink to the renamed original directory can pass the inode check and make the write return success.

## Issue Context
The namespace validation must establish, at one linearization point, both that every parent was opened with `O_NOFOLLOW` and that the final basename in that verified parent refers to the created inode. A separate full-path stat cannot provide that guarantee because `follow_symlinks=False` protects only the basename.

1. Search-only directories are rejected ✗ Dismissed

Description

The parent walk opens every directory with O_RDONLY, so a directory that grants write/search

2. Artifact writing becomes Linux-only 🐞 Bug ≡ Correctness

Description

write_artifact now unconditionally delegates to a primitive that refuses writes unless Linux
openat2 is available through libc or the x86-64 syscall fallback, so the maintenance command

support declaration and leaves no alternate artifact-writing path.
