Exact head: 081998e

Canonical base: 06e5154
Correctness/safety review completed against the final two-file diff and current Codex App Server protocol. The earlier environment-isolation gap was not waived: it was repaired by T079-only experimental opt-in plus explicit empty environments/runtime roots/dynamic tools/capability roots, returned-root/instruction-source validation, and future-fail-closed item handling. Stable T077 initialization remains stable-only.
Verified invariants:
- mandatory initialize -> successful response -> initialized before later requests;
- exact runtime identity and exact locally observed version revalidated before launch;
- one ephemeral thread and one fixed bounded prompt only;
- no arbitrary model/prompt/tool/policy surface;
- approvalPolicy=never plus explicit decline on unexpected command/file approvals;
- readOnly + networkAccess=false;
- environment access disabled explicitly;
- zero runtime workspace roots and zero instruction sources required from thread evidence;
- MCP/tool/hook/web-search/image-generation/collaboration/subagent/diff activity is non-authorizing and fail-closed;
- unknown item kinds are fail-closed;
- native thread identity remains separate from Winds session identity;
- model output remains AGENT_RUNTIME_EVIDENCE_NOT_VERIFIED_OR_ACCEPTED;
- cleanup targets only the directly owned child; mutated disposable context is preserved rather than erased;
- no migration, store/domain schema, dependency, main.rs, generic agent surface, or landing automation change.
Exact-head gates:
- quality #739: PASS
- windows-terminal #445: PASS
- release-candidate #502: PASS after same-SHA T063 Windows timing rerun; no code mutation or waiver
- unit: 242 pass / 0 fail / 3 ignored
- T079 deterministic: 7/7 PASS
- live T079 proof: intentionally still PENDING

PONYTAIL_T079_PASS_NO_REQUIRED_REMOVALS
Exact head: 081998e
YAGNI/minimum-surface review: PASS.
The final diff is limited to the existing Codex protocol module plus one focused T079 test module. The implementation does not add a JSON-RPC framework, async runtime, persistence/migration, generic model chooser, arbitrary prompt API, reusable approval engine, ACP/MCP integration, daemon IPC, remote execution, provider abstraction, primary-checkout mutation, PR/push/merge automation, or automatic landing.
The T079-only experimental initializer is justified by a concrete upstream protocol requirement: explicit environments=[], runtimeWorkspaceRoots=[], dynamicTools=[], and selectedCapabilityRoots=[] are needed to make the first connected proof fail closed rather than inherit default environment/capability surfaces. The normal T077 initializer remains unchanged in behavior.
No further extraction/generalization is required before the first bounded connected proof. Persistence is not required to satisfy T079 provenance because the receipt binds the supplied Winds session id to the returned native thread/turn identities without conflating those namespaces.

@coderabbitai review Please perform a fresh independent review of exact head T079 is the first bounded real-Codex proof surface, but the live proof has NOT run yet. Please focus on material correctness, protocol compatibility, fail-closed authority, environment/MCP/tool isolation, process cleanup/ownership, provenance separation, and any path that could mutate the primary checkout or widen permissions. Do not infer verification/acceptance from model output. Report all material findings on this exact head. |

High-Level Assessment

Fresh review of the supplied T079 diff identifies three material findings: finding 1 — Unknown runtime notifications are not rejected (high)
Location: Recommendation: Replace the blacklist with an explicit allowlist of the exact notification methods and item types required for this proof; reject every unknown method/type, including notifications with unexpected parameter shapes. finding 2 — Effective-config validation is an incomplete allowlist (high)
Location: Recommendation: Validate the complete App Server effective-config schema/version and require an explicitly empty or disabled configuration, rejecting unknown keys and unexpected value shapes. If the API cannot provide a complete authoritative config, fail the proof rather than relying on selected fields. finding 3 — Spawned Codex can be leaked on setup failure (medium)After Location: Recommendation: Put child ownership under an RAII cleanup guard immediately after spawn, or explicitly kill/reap on every subsequent setup failure; separately remove the temporary root on all failure paths where it remains unchanged. The bounded prompt, fixed request construction, approval decline behavior, empty workspace roots, read-only/no-network request fields, identity revalidation, transcript limits, and direct-child cleanup on the normal proof path otherwise look directionally sound. The ignored live proof remains pending, and these issues should be addressed before treating T079 as a completed safety proof. |

288-314: 🚀 Performance & Scalability | 🔵 Trivial | 💤 Low valueBound the frame reader, not only the frame consumer.
The reader thread enforces the per-frame cap and then pushes into an unbounded channel.
MAX_CONNECTED_BYTESandMAX_CONNECTED_FRAMESapply only inreceive_frame. A server that streams frames faster than the proof consumes them can therefore hold far more than 1 MiB in the channel queue.Use
mpsc::sync_channelwith a small bound, or track the cumulative byte count in the reader and stop early. That makes the transcript bound an actual memory bound.🤖 Prompt for AI Agents

221-258: 🩺 Stability & Availability | 🔵 Trivial | 💤 Low valueRead
--versionstdout while the child runs, not after it exits.The function polls
try_waitto completion before it reads the piped stdout. If the child writes more than the pipe buffer holds, the child blocks on write, never exits, and the loop reports "T079 Codex --version exceeded bounded timeout". The real cause is the unread pipe. The bound keeps this safe, but the error text becomes misleading.Read the bounded stdout into the buffer first, then wait for exit and check the status. That keeps the same byte cap and the same timeout semantics.

- Around line 276-336: Update the sandbox value in t079_thread_start to
"read-only" instead of "readOnly"; leave the rest of the thread/start request
unchanged.
In `@src/t079_codex_connected_tests.rs`:
- Around line 500-520: Ensure the temporary directory created by disposable_root
is cleaned up when early errors occur before the existing cleanup block,
including UTF-8 conversion, process spawn, and missing stdin/stdout handles.
Update the setup flow around Command::new and the child stdio extraction to
remove the root on failure or use a Drop guard that only removes it while empty,
while preserving the existing cleanup behavior after the test runs.
- Around line 890-921: Update the test function
runtime_identity_must_match_exact_codex_discovery_before_launch to guarantee
removal of root regardless of assertion or validation failure, using
unconditional cleanup while preserving the existing sha256 identity assertions.
- Around line 97-119: Update validate_effective_config to inspect flattened and
camelCase effective-config fields, rejecting any unsupported field with a
meaningful value rather than checking only the seven known snake_case keys.
Preserve acceptance of empty or absent fields, and add coverage for active
mcpServers and an active unknown flattened field.

@codex fix Implement only the two verified unresolved P1 findings from the fresh Codex review on exact head Required repairs:
Keep the repair minimal and T079-only. Prefer changing only Hard boundaries:
Run only deterministic repository checks/tests that cannot invoke the ignored live proof. If you can safely commit to the existing PR branch, use one minimal commit. Report the exact resulting SHA, changed files, tests run, and whether both P1 findings are fully repaired. |

4. Child stderr discarded entirely 🐞 Bug ◔ Observability
The harness sets Codex child stderr to Stdio::null(), so when the proof fails (startup/config/handshake), there is no bounded stderr capture to aid diagnosis. This makes failures harder to debug and can increase flakiness triage time without improving correctness or safety of the proof verdicts.
Agent Prompt
### Issue description
The T079 harness currently discards the Codex child process stderr (`stderr(Stdio::null())`). When the proof fails during startup/handshake/config, there is no stderr context to explain why.
### Issue Context
The harness is already designed around bounded I/O and bounded-time cleanup. Adding a small bounded stderr capture (only surfaced on failure) improves debuggability while keeping output bounded.
### Fix Focus Areas
- src/t079_codex_connected_tests.rs[1798-1825]
### Suggested fix
- Change `stderr(Stdio::null())` to `stderr(Stdio::piped())`.
- Read stderr in a bounded way (size cap + timeout) similar to the stdout reader, but only attach it to error messages when the proof fails.
- Ensure stderr capture is also included in cleanup/termination paths so it cannot hang the harness (use non-blocking reads or a dedicated bounded reader thread like stdout).

@coderabbitai Implement the four new Qodo findings from review Scope strictly to:
Required repair:
In code, add the smallest deterministic preflight helper that makes this true. Prefer a pure architecture validator (for example, validate the supplied architecture string against exactly
Hard prohibitions:
Run deterministic non-ignored format/tests/checks only. If branch writes are supported, commit the minimal repair directly to this PR branch and report the exact new SHA, changed paths, and validation evidence. If anything outside the two permitted files is required, stop instead of widening scope. |

The requested repair fits the two permitted files. The current source confirms the existing system-config checks, seccomp filter, sealed executable binding, and I also used the repository learning about sealed pre-version binding. The repair will preserve that binding and its fail-closed identity check. T079 minimal repair plan

The repair can remain within the two permitted files. I used the existing sealed pre-version binding requirement from the repository learning. The repair preserves that requirement.
A code-change agent must produce the commit SHA after it applies the repair and runs the permitted deterministic checks. The repair does not close T079. Fresh exact-head CI, reviews, and separately authorized live proof remain required. 🧠 Learnings used

Current review state
A newer Qodo review (
5018337406) on this exact head supersedes the earlier clean-review summary and opened four findings:No finding is waived. The previous
PASS_NO_MATERIAL_FINDINGSstatus is therefore not current qualification evidence.Existing exact-head fail-closed repairs
The current exact head already includes, among other cumulative T079 repairs:
memfdexecutable binding before the first bounded--versionobservation;run_connected_proof;CODEX_HOMEvalidation rejecting the primary checkout and every canonical descendant;execve;Stdio::null()and is not surfaced as raw proof evidence.Live-proof authority and closure state
No live Codex/App Server proof has been run during this qualification cycle. No
config/read,thread/start,turn/start, or T079 prompt has been sent as part of this deterministic/review reconciliation.The prior live-attempt authority does not grant a retry. A new live attempt requires separate explicit founder authorization; a generic continuation instruction is not sufficient under the active T079 gate.
Do not run a live Codex proof, send live App Server requests, merge PR #80, or start T080 without the separate authority required by the active Spec 006 gate.
