What

The client half of AgentEye's request trail (FailproofAI/agenteye#1044). Every call into AgentEye from this repo now carries an id the server validates and logs, so a user's ref 4bf92f35 finds the request end to end.

Client Change
failproofaid (crates/fpai-collect) x-request-id (new per attempt), x-failproofai-batch-id (hash of the spool file's base name: stable across retries, the rename to a parked name, and the failed/ re-drive), x-failproofai-machine-id (collector.machine_id, else unknown; never the telemetry id). The server's response id is logged when a batch is parked. No sidecar file: the filename stays the only metadata.
fp (fp-cloud-cli) request_id on every error type in --json; human errors end with · ref <8>; ids on the login/logout calls that used their own HTTP clients. Exit codes and existing envelope keys unchanged.
Evaluator SDK X-Request-Id on every call (shared by that call's retries); request_id_scope() to set it; the id on every EvaluatorAPIError, including network errors.
Docs Troubleshooting, HTTP API and Cloud CLI pages: quote the ref / request_id to support; send your own X-Request-Id (32 hex) to correlate.

Ids are 32 lowercase hex (a W3C trace id). The AgentEye server replaces anything else, so older clients keep working and a hostile value never reaches a log line.

Tests

  • crates/fpai-collect: 3 unit + 2 mock-server tests (three attempts of one batch: distinct request ids, one batch id, id survives the park rename); crate suite green; clippy -D warnings clean on both crates.
  • fp-cloud-cli: 10 new tests in tests/test_request_id.py; full suite 954 passed.
  • SDK: 9 new tests in tests/test_evaluator_request_id.py, including the runtime's real claim-failure path; 1146 passed. The 70 errors are all tests/integrations/test_langchain.py in a fresh venv that resolved langchain-core 1.4.0 (the adapter needs 1.4.7), unrelated.
  • Docs: bun run validate:mdx — 1061 pages parse cleanly.

Summary

The durability follow-up correctly syncs the destination directory before deleting the source. Three low-severity issues remain in the new request-ID paths: evaluator error-envelope IDs can inject logs, OTP failures omit IDs, and collision-renamed parked batches lose their stable batch ID.

Changes

  • Adds request, batch, and machine identity headers to collector uploads and crash-safe cross-filesystem parking.
  • Adds request IDs to Cloud CLI HTTP errors and human/JSON error output.
  • Adds evaluator request-ID propagation, scoped IDs, and runtime log correlation.
  • Documents request-ID support and updates dependency lockfiles.

Validation

  • Passed docker run --rm --network=none -v /review/input/workspace:/workspace:ro -w /workspace/sdk/python python:3.12-slim sh -lc 'PYTHONPYCACHEPREFIX=/tmp/pycache python -m py_compile failproofai_sdk/evaluator/__init__.py failproofai_sdk/evaluator/client.py failproofai_sdk/evaluator/runtime.py' — Changed evaluator SDK modules compiled successfully in a nested container. (1s)
  • Skipped docker run --rm --network=none -e RUSTUP_TOOLCHAIN=1.91.1 -v /review/input/workspace:/workspace:ro -w /workspace rust:1.91-slim cargo test -p fpai-collect --no-run — The isolated container has no cached Cargo dependencies and cannot resolve crates.io; this harness limitation cannot be resolved by the author. (11s)
  • Skipped docker run --rm -v /review/input/workspace:/workspace:ro -w /workspace/fp-cloud-cli python:3.12-slim sh -lc 'python -m pip install --disable-pip-version-check -q ".[dev]" && pytest -q tests/test_request_id.py' — The nested environment could not provision the dependency-backed Python test environment from its package registry, so the test result was unavailable. (25s)

Findings

No blocking findings.

3 advisory findings
  • Low/High Unvalidated error-envelope IDs can forge evaluator log entries — _http_error() selects response.error.request_id without applying _SANE_ECHO at sdk/python/failproofai_sdk/evaluator/client.py:373; runtime paths interpolate that value into plain-text warning messages. A nested-container reproducer returned an envelope ID of forged\nlog-entry alongside a valid response header, and the resulting EvaluatorAPIError.request_id preserved the newline. (sdk/python/failproofai_sdk/evaluator/client.py:373)
  • Low/High OTP request failures omit the request reference — Both OTP request paths catch httpx.RequestError and call _network_error() at fp-cloud-cli/fp_cli/auth.py:61 and :92, but _network_error() constructs NetworkError without the sent x-request-id at line 31. The successful verify response missing ae_session also raises AuthError without _request_id_of(response) at line 118. These reachable errors therefore lack both the human ref and JSON request_id promised by this change. (fp-cloud-cli/fp_cli/auth.py:31)
  • Low/High Collision-renamed parked batches lose their batch identity — When the intended failed-directory name exists, unique_destination() appends .1 after the complete filename (crates/fpai-collect/src/uploader.rs:855), producing names such as batch.a1.jsonl.1. ParkedName::parse() only removes a terminal .jsonl before parsing retry suffixes, so a later re-drive hashes the entire collision-suffixed name and treats its attempt as zero. The same undelivered batch consequently gets a different x-failproofai-batch-id and reset retry state. (crates/fpai-collect/src/uploader.rs:850)

📝 Walkthrough

Walkthrough

Daemon uploads, Cloud CLI requests, and Python evaluator calls now carry request IDs into errors and logs. Uploads also carry batch and machine IDs. The changes update upload parking, CLI error references, evaluator logging, and related documentation.

Changes

Request identity propagation

Layer / File(s) Summary
Uploader identity, retries, and parking
crates/fpai-collect/Cargo.toml, crates/fpai-collect/src/uploader.rs, crates/fpai-collect/src/delivery.rs, crates/fpai-collect/tests/uploader.rs, crates/failproofaid/src/main.rs
Uploads send request, batch, and machine ID headers. Request IDs change per attempt; batch IDs remain stable across retries and parked-name changes. Retry and parking logs include identifiers. Parking supports copy-based movement across filesystems, and parked-batch scanning excludes dotfiles.
Cloud CLI request IDs and error references
fp-cloud-cli/fp_cli/errors.py, fp-cloud-cli/fp_cli/client.py, fp-cloud-cli/fp_cli/auth.py, fp-cloud-cli/fp_cli/app.py, fp-cloud-cli/tests/test_request_id.py, docs/reference/cloud-cli.mdx, docs/reference/http-api.mdx
CLI requests send request IDs and propagate them into typed errors. Human-readable errors show short references; JSON errors include the full ID. Authentication requests also send IDs. Tests and reference documentation cover these behaviors.
Evaluator request IDs and logging
sdk/python/failproofai_sdk/evaluator/*, sdk/python/tests/test_evaluator_request_id.py
Evaluator calls generate or use scoped request IDs and reuse each ID across retries. Errors and runtime failure logs include request IDs. Tests cover propagation, context scope, and logging.
Release and support references
CHANGELOG.md, docs/reference/troubleshooting.mdx, package.json
The changelog records the release changes and dependency updates. Troubleshooting guidance describes error references and upload identifiers. The brace-expansion override changes to version 5.0.12.

Merge Risk: 🟡 Moderate · up to 34568

Request IDs now flow through uploads, CLI errors, and evaluator calls. However, when a failed upload batch is moved across filesystems, a power loss at the wrong moment can lose that batch. Several smaller request-ID gaps also remain in error references and ID generation. The durability fix should be made before merging.

Security Architecture Review

Security architecture risk: 🔵 Low · up to 34568

Request correlation remains separate from authentication. The main unresolved risks are filesystem access during cross-volume parking and validation of evaluator identifiers before logging. Exploitation would require local access to the retry directory or control of the configured API response; broader exposure is not established.

Retained concerns

  • Medium · security · inferred: The new cross-filesystem path copies telemetry into a predictable partial filename without exclusive creation or no-follow protection. If a lower-trust principal can populate state/failed, a pre-existing partial symlink could redirect that write to another file writable by the daemon. This write-through operation is new relative to direct rename. Private directory ownership would block the prerequisite, but deployed ownership and permissions are not established.
  • Low · security · inferred: Evaluator error envelopes take precedence over validated response-header IDs, and their request_id now enters plain-text runtime warnings. This path does not use the echoed-ID validator. The generic protocol string validator and production server enforcement were not established, leaving a sanitation gap at the new logging boundary. Any attack requires influence over the configured API response; tenant-controlled reachability is not demonstrated.
Security review details

Security Blast Radius

  • inferred — The conditional partial-path attack is bounded by filesystem locations writable by the daemon process. It requires access to the failed directory and a cross-device parking operation; no root authority, cross-tenant access, or remote route to that prerequisite is established.

Security Findings and Attack Paths

  • inferred — A principal able to create the predictable partial entry could attempt to redirect copy/open operations through a symlink. Separately, an API responder's envelope request_id can reach new evaluator warning messages without passing through the header-specific validator. These are conditional architecture concerns, not verified production exploitation.

Trust Boundaries and Controls

  • observed — Credential writing attempts to tighten the home directory to 0700, providing counterevidence to a writable retry-directory attack. That operation is best-effort, and the inspected configuration-loading path does not enforce failed-directory ownership or permissions.

Resilience and Maintainability Implications

  • observed — Watcher and sweeper share one Delivery instance, semaphore, and in-flight path set. This contains concurrent processing of the same path within that instance, but does not reserve a destination for different source paths or coordinate separate processes.

Hardening Proposals

  • proposed — Make retry-directory ownership an explicit invariant and use exclusive, symlink-resistant partial creation with atomic destination reservation. Define cleanup and reconciliation for abandoned partials and publication-before-source-removal failures.
  • proposed — Apply one bounded identifier validator to both envelope and header values before selecting the ID used in errors and plain-text logs, rather than relying on production server behavior.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Preserve the request ID on organization-probe 401 errors.

If the organization probe returns 401, org_is_accessible raises AuthError without the response request ID. The CLI therefore omits the reference for this failed request. Pass request_id=_request_id_of(response) to this error, as the other status handlers do.

Carry the OTP request ID into network errors.

If an OTP request raises httpx.RequestError, _network_error discards the ID on exc.request. Both OTP clients now send that ID, but neither network failure can show it in the CLI error. Extract the outgoing ID in this helper and pass it to NetworkError.

2 advisory findings
  • Medium/High Keep the batch ID stable when a parked filename collides — batch_id() hashes ParkedName::parse(name).base. When unique_destination() has to preserve an existing parked file it creates names such as hooks-s-1-0.a1.jsonl.1; that name no longer ends in .jsonl, so ParkedName::parse cannot remove .a1 and hashes the full collision name instead of the original base. A failed/ retry of that valid collision path therefore emits a different x-failproofai-batch-id, contrary to the requested stable cross-retry identifier. (crates/fpai-collect/src/uploader.rs:597)
  • Medium/High Propagate request IDs through the remaining CLI failure paths — verify_otp() now sends an x-request-id, but when a 200 response lacks ae_session it raises AuthError at line 118 without _request_id_of(response). The same omission remains for the org-accessibility 401 path and the SSE transport NetworkError. These reachable fp failures consequently show neither the human ref nor the JSON request_id, despite the new CLI contract and documentation. (fp-cloud-cli/fp_cli/auth.py:118)

2 advisory findings
  • Low/High Login and streamed-command transport failures drop their request IDs — The regular client paths preserve the sent ID with _sent_request_id(exc), but auth._network_error() constructs NetworkError without one (auth.py:31), so failed OTP requests at lines 61-62 and 92-93 have no ref or JSON request_id. _stream_sse() repeats this omission at client.py:1493-1494. A successful OTP response missing ae_session also raises AuthError without _request_id_of(response) at auth.py:116-118. (fp-cloud-cli/fp_cli/client.py:1494)
  • Low/High Evaluator error-body request IDs bypass response-ID validation — RemoteError.from_wire() accepts any string for request_id (protocol.py:738-742), and _http_error() selects that value before the validated header/sent ID (client.py:368-373). The runtime then interpolates it into log messages (runtime.py:941-945). A nested-container repro supplied an error body with request_id equal to forged\nline and a valid X-Request-Id header; _http_error() returned the multiline body value.

Companion to AgentEye's request-trail change: every hop into AgentEye now
carries an id the server logs, so one search finds a request end to end.

- Daemon uploads send x-request-id (new per attempt), x-failproofai-batch-id
  (hash of the spool file's base name: stable across retries and the failed/
  re-drive) and x-failproofai-machine-id (collector.machine_id, else unknown).
  The server's response id is logged when a batch is parked.
- fp: request_id on every error type, "· ref <8>" on human errors, and ids on
  the login/logout calls that used their own HTTP clients.
- Evaluator SDK: X-Request-Id on every call (shared by that call's retries),
  request_id_scope() for callers, and the id on every EvaluatorAPIError.
- Docs: troubleshooting, HTTP API and Cloud CLI pages explain the ref.

3 advisory findings
  • Medium/High Login-flow failures omit the request reference — auth.py adds an x-request-id to OTP clients, but _network_error() at line 31 constructs NetworkError without the ID available on httpx.RequestError.request; both OTP network-error handlers use it (lines 62 and 93). The successful HTTP response that lacks ae_session also raises AuthError at line 118 without _request_id_of(response). These login failures therefore do not render ref or emit request_id in JSON despite the feature applying IDs to login calls and every error type. (fp-cloud-cli/fp_cli/auth.py:31)
  • Low/High Unvalidated error-envelope IDs reach runtime logs — RemoteError.from_wire() accepts any string as request_id (protocol.py line 742), and _http_error() prefers that value over the validated response header/sent ID (client.py line 373). The runtime interpolates it directly into warning and exception messages (for example runtime.py line 942). A malformed error body containing control characters can therefore forge or split log records, bypassing _SANE_ECHO. (sdk/python/failproofai_sdk/evaluator/client.py:373)
  • Low/High Collision-suffixed parked uploads receive a new batch ID — When a parked destination already exists, unique_destination() creates names such as batch.a1.jsonl.1 (uploader.rs lines 787-798). ParkedName::parse() only understands names ending in .jsonl (lines 698-724), so batch_id() hashes that entire collision-suffixed name rather than the original base name (lines 591-599). On its failed-directory re-drive, this same batch consequently gets a different x-failproofai-batch-id, breaking the stated cross-retry log correlation. (crates/fpai-collect/src/uploader.rs:787)

3 advisory findings
  • Low/High Validate evaluator error-body request IDs before logging — _http_error() prefers response.error.request_id at line 373, while RemoteError.from_wire() accepts any string. The runtime interpolates that value into log messages. A nested-container reproducer supplied forged\nline in a valid error envelope alongside a valid header and received that multiline body value unchanged. (sdk/python/failproofai_sdk/evaluator/client.py:373)
  • Low/High Preserve request references on OTP failure paths — OTP calls now send an ID, but both RequestError handlers call _network_error(), which constructs NetworkError without the request's sent ID. The successful-response path that lacks ae_session also raises AuthError without _request_id_of(response). Those login failures therefore omit both ref and JSON request_id. (fp-cloud-cli/fp_cli/auth.py:31)
  • Low/High Keep batch IDs stable for collision-suffixed parked files — When a parked destination exists, unique_destination() creates names such as batch.a1.jsonl.1. ParkedName::parse() only recognizes a terminal .jsonl, so batch_id() hashes this whole collision-suffixed name on its failed-directory re-drive rather than the original base. The same batch is then sent with a different batch ID. (crates/fpai-collect/src/uploader.rs:787)

🟡 Minor · Normalize collision suffixes before deriving the batch ID. · uploader.rs:599-610

crates/fpai-collect/src/uploader.rs:599-610
🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Normalize collision suffixes before deriving the batch ID.

When failed/ already contains the target name, unique_destination creates names such as base.a1.jsonl.1. retry_parked still re-drives that file, but ParkedName::parse leaves .1 in base. batch_id then hashes a different base and sends a different ID for the same batch history. Strip the collision suffix before parsing the normal parked-name suffixes.

Found by the container end-to-end test of the request trail:

- A failed upload attempt was logged only at DEBUG, so at the default level
  a customer's log showed the last attempt (on the park line) and none of the
  ones before it. Each attempt has its own request id; the retry line is the
  only place that ties it to the batch. It is now a WARN.
- The final "upload failed" line now carries the batch id, so it joins the
  attempt and park lines.
- Parking used a plain rename, which fails with EXDEV when the spool and
  state directories are on different filesystems (an SDK spool on its own
  Docker volume). The batch stayed in the spool and a 401/poison batch was
  re-sent on every sweep. Parking now falls back to copy (to a hidden name,
  fsynced, renamed into place) then remove; the parked-batch sweep skips
  dotfiles, so it never sees a half-copied park.
- Troubleshooting: where the daemon logs request_id and batch_id.

I could not establish complete review coverage for 345684485e20, so I did not approve it. I have no specific question to ask — this is a coverage gap on my side, not a request for input.

What the review did establish:

Request correlation is implemented across collector uploads, the Cloud CLI, and evaluator calls, but three reachable paths break the stated correlation contract or log safety. Full Rust and Python test suites could not be bootstrapped in the nested-container environment.

Re-run with @hermes-exosphere review [focus] to point me at the part that matters most, or @hermes-exosphere reconsider [reason] if you believe the coverage was sufficient.

Follow-up: 34568448, from the containerised end-to-end test

  • Every upload attempt is findable. The "attempt failed; retrying" line was DEBUG, so at the default level only the last attempt (on the park line) showed an id. It is now WARN, with request_id and batch_id. The final "upload failed" line also carries batch_id. Verified: in a server outage, 4 of 4 failed attempt ids were in the daemon's own log, each naming the batch that later landed.
  • Parking across filesystems. A plain rename failed with EXDEV when the spool and state directories were on different mounts, for example an SDK spool on its own Docker volume. A 401 or poison batch then stayed in the spool and was re-sent on every sweep. Parking now falls back to copy (hidden name, fsync, rename into place), then remove, and the sweep skips dotfiles. Verified: a batch was parked across two volumes, re-sent on the next retry pass, and landed with the same batch_id.
  • Docs: the troubleshooting page has a Daemon tab saying where request_id and batch_id appear. The CHANGELOG has entries under Fixes.

Tests: fpai-collect passes, including a new copy-then-remove test and a sweep-filter test, and clippy is clean. claude_source and factory_source flake under heavy load on the base commit too.
Telemetry: no new user action. These are log lines and a file move, so there is no event to add.

@hermes-exosphere review: please focus on the request-id correlation paths (collector uploads, fp refs, evaluator SDK calls) and your three advisory findings. Below is the test coverage your sandbox couldn't bootstrap last time, run locally on 34568448.

Local validation on 34568448

  • cargo test -p fpai-collect: 577 passed, 0 failed across 25 test binaries. cargo clippy -p fpai-collect --all-targets -- -D warnings: clean.
  • sdk/python, uv run pytest -q: 1146 passed, 5 skipped. tests/test_evaluator_request_id.py: 9/9.
    • It also shows 70 errors. All are teardown errors in tests/integrations/test_langchain.py, and origin/main shows the same 70 (94 passed, 70 errors). They come from the local environment's langchain-core 1.4.0, which is below the adapter's 1.4.7 floor. This PR doesn't touch that file.
  • fp-cloud-cli, uv run pytest -q: 954 passed.
  • End-to-end in containers. The daemon, an SDK agent and a customer-hosted evaluator ran against the cloud stack from FailproofAI/agenteye#1044:
    • Uploads: every attempt's x-request-id, plus the batch and machine ids, appear at the edge and on the server.
    • Wrong key: 9/9.
    • Server outage with retries: 13/13. Every failed attempt's id and batch id are in the daemon's own log. A batch parked across two volumes was re-sent and landed with the same batch_id.

Hermes found blocking issues that should be addressed.

High: Cross-filesystem parking can lose the only undelivered batch after a crash

  • Rule: DATA-001
  • Location: crates/fpai-collect/src/uploader.rs:605
  • Evidence: copy_then_remove() fsyncs the temporary file, renames it at line 605, then immediately deletes the source at line 606. It never fsyncs the destination directory, so a power failure can persist the source deletion while losing the new directory entry. This affects the new EXDEV fallback, where the source is the last retryable copy.
  • Required change: After renaming the temporary file, open and sync the destination parent directory before removing the source. If that sync fails, return the error with the source intact; optionally sync the source parent after removal to reduce duplicate replays.
3 advisory findings
  • Low/High Error-envelope request IDs bypass validation before reaching worker logs — _http_error() accepts any string parsed from response.error.request_id at line 373, while only response headers pass _SANE_ECHO validation. The runtime interpolates this value into warning and exception messages. A nested-container reproducer returned an error envelope containing "forged\nlog" and _http_error() preserved that value despite a valid response header. (sdk/python/failproofai_sdk/evaluator/client.py:373)
  • Low/High OTP failure paths still omit request references — Both OTP RequestError handlers call _network_error(), which constructs NetworkError without exc.request's x-request-id (lines 31, 61-62, and 92-93). The successful verify response that lacks ae_session also raises AuthError without _request_id_of(response) at line 118. These errors therefore emit neither ref nor JSON request_id. (fp-cloud-cli/fp_cli/auth.py:31)
  • Low/High Collision-renamed parked batches get a different batch ID — unique_destination() creates names such as batch.a1.jsonl.1 when a destination exists (line 835). ParkedName::parse() only strips a terminal .jsonl, so batch_id() hashes the collision-suffixed name on its failed-directory re-drive rather than the original base. The same batch then sends a different x-failproofai-batch-id and its parsed retry state resets. (crates/fpai-collect/src/uploader.rs:835)

Comment thread crates/fpai-collect/src/uploader.rs
Hermes (review of 3456844): copy_then_remove renamed the fsynced copy into
place and deleted the source straight away, without fsyncing the destination
directory. A power cut could persist the source deletion and lose the new
directory entry, and the source was the last copy of an undelivered batch.

The destination directory is now fsynced after the rename and before the
source is removed (Unix; NTFS journals the rename itself). A failed flush is
an error, so the source survives it.

@hermes-exosphere review: copy_then_remove now fsyncs the destination directory after the rename and before removing the source (crates/fpai-collect/src/uploader.rs). A failed flush is returned as an error, so the source survives it. The commit adds a test for the directory flush.

Local run on the new head: cargo test -p fpai-collect gives 578 passed, 0 failed (twice), and cargo clippy -p fpai-collect --all-targets -- -D warnings is clean.

The three advisory findings are left as they are in this PR.

OSV-Scanner flagged urllib3 2.7.0 (GHSA-8988-9cw3-xx77, GHSA-gh4c-6fx4-qh6g,
GHSA-vxq7-64xx-v4gw; fixed in 2.8.0) in fp-cloud-cli/uv.lock and
sdk/python/uv.lock. `uv lock --upgrade-package urllib3` in both; nothing else
moved. fp-cloud-cli 954 passed; SDK suite unchanged (1146 passed).

3 advisory findings
  • Low/High Unvalidated error-envelope IDs can forge evaluator log entries — _http_error() selects response.error.request_id without applying _SANE_ECHO at sdk/python/failproofai_sdk/evaluator/client.py:373; runtime paths interpolate that value into plain-text warning messages. A nested-container reproducer returned an envelope ID of forged\nlog-entry alongside a valid response header, and the resulting EvaluatorAPIError.request_id preserved the newline. (sdk/python/failproofai_sdk/evaluator/client.py:373)
  • Low/High OTP request failures omit the request reference — Both OTP request paths catch httpx.RequestError and call _network_error() at fp-cloud-cli/fp_cli/auth.py:61 and :92, but _network_error() constructs NetworkError without the sent x-request-id at line 31. The successful verify response missing ae_session also raises AuthError without _request_id_of(response) at line 118. These reachable errors therefore lack both the human ref and JSON request_id promised by this change. (fp-cloud-cli/fp_cli/auth.py:31)
  • Low/High Collision-renamed parked batches lose their batch identity — When the intended failed-directory name exists, unique_destination() appends .1 after the complete filename (crates/fpai-collect/src/uploader.rs:855), producing names such as batch.a1.jsonl.1. ParkedName::parse() only removes a terminal .jsonl before parsing retry suffixes, so a later re-drive hashes the entire collision-suffixed name and treats its attempt as zero. The same undelivered batch consequently gets a different x-failproofai-batch-id and reset retry state. (crates/fpai-collect/src/uploader.rs:850)
