Thanks for adding the object-body guard and regression coverage. The issue repros now return JSON 400s, but I am requesting changes because ttl_seconds is still not strictly validated as an integer for JSON numeric payloads.

Validation run against head db189236d945f4f8743794a72250d28e42f2823d:

git diff --check origin/main...HEAD -- otc-bridge/otc_bridge.py otc-bridge/test_otc_bridge.py tests/test_otc_bridge_query_validation.py

  tests/test_otc_bridge_query_validation.py::test_order_create_accepts_valid_buy_order_with_ttl \
  --noconftest
# 6 passed in 0.90s

Focused Flask probe results:

array_body      -> 400 {'error': 'JSON object required'}
ttl_abc         -> 400 {'error': 'ttl_seconds must be an integer'}
ttl_bool_json   -> 400 {'error': 'ttl_seconds must be an integer'}
ttl_valid_string-> 201 {... 'ok': True, 'expires_in_hours': 1.0 ...}
ttl_float_json  -> 201 {... 'ok': True, 'expires_in_hours': 1.0 ...}

Blocking finding: parse_order_ttl() uses int(raw), so a client can still send a non-integral JSON number such as 3600.5; Python truncates it to 3600 and the route creates the order instead of returning the expected ttl_seconds must be an integer 400. That leaves part of #5525's invalid-ttl_seconds validation boundary open.

Suggested fix: reject bool and non-integral float values before int(...) (or parse from string with an explicit integer pattern), then add a regression for ttl_seconds: 3600.5 returning 400. The existing object-body and "abc" paths look good once that gap is closed.

Thanks for tightening the array-body and string TTL cases. The new tests pass for the original repro, but parse_order_ttl() still accepts non-integer JSON numbers because it relies on int(raw) before clamping.

At head db189236d945f4f8743794a72250d28e42f2823d, a JSON float is silently truncated and the order is accepted:

POST /api/orders { ..., "ttl_seconds": 1.5 } -> 201, expires_in_hours: 1.0

That is still malformed input for an integer-seconds field, and it is surprising because 1.5 becomes 1 and then gets clamped to the one-hour minimum. The new bool guard is good, and decimal strings such as "1.5" already return the intended 400; the remaining gap is JSON float values.

Validation I ran locally:

git diff --check origin/main...HEAD -- otc-bridge/otc_bridge.py otc-bridge/test_otc_bridge.py tests/test_otc_bridge_query_validation.py  # passed
python3 -B -m py_compile otc-bridge/otc_bridge.py otc-bridge/test_otc_bridge.py tests/test_otc_bridge_query_validation.py  # passed
uv run --no-project --with pytest --with flask --with requests python -B -m pytest -q tests/test_otc_bridge_query_validation.py  # 12 passed
Flask test-client probe:
  ttl_seconds="abc" -> 400 JSON
  ttl_seconds=true -> 400 JSON
  ttl_seconds=1.5 -> 201 JSON (should be 400)
  ttl_seconds="1.5" -> 400 JSON
  ttl_seconds=7200 -> 201 JSON

I would change the parser to accept only real int values (excluding bool) or decimal integer strings, and add a regression for ttl_seconds=1.5 returning {"error": "ttl_seconds must be an integer"}.

Updated in head 829d9eeaf027b299d97a8d6c7d2e0c29b15ae7f2 to address the float TTL review blocker.

Changes:

parse_order_ttl() now accepts real int values and integer-format strings.
bool, floats such as 3600.5, decimal strings such as "1.5", empty strings, and other non-integer values return {"error": "ttl_seconds must be an integer"}.
Added regressions for JSON float TTL values in both OTC bridge test surfaces.

I re-reviewed the updated head 829d9eeaf027b299d97a8d6c7d2e0c29b15ae7f2.

The update resolves the earlier blocker around lossy ttl_seconds coercion. parse_order_ttl() now accepts real integers and decimal integer strings, explicitly rejects booleans, and rejects floats / fractional strings instead of passing them through int(...). That closes the ttl_seconds=3600.5 path that previously created a one-hour order.

Validation run in a clean temporary worktree based on origin/main with the current PR patch applied:

git diff --check --cached
passed

python -B -m py_compile otc-bridge/otc_bridge.py otc-bridge/test_otc_bridge.py tests/test_otc_bridge_query_validation.py

5 passed, 25 deselected

I also directly probed parse_order_ttl():

'abc'    -> error
True     -> error
3600.5   -> error
'3600.5' -> error
'7200'   -> 7200
7200     -> 7200

No remaining blocker from this review.

Reviewed current head 829d9ee. This resolves the TTL validation blocker from the earlier review thread: parse_order_ttl() now rejects booleans before the integer branch, accepts only real integer values or integer-format strings, and returns the same JSON 400 for JSON floats/decimal strings instead of truncating them through int(...).

The new coverage also checks the important surfaces on both OTC test paths: non-object JSON bodies, non-integer TTL strings, JSON float TTL values, and a valid TTL buy order.

Validate OTC order payloads. Good input validation. Verify: (1) All numeric fields reject NaN/Infinity. (2) String fields have length limits to prevent DoS. (3) No SQL/NoSQL injection vectors in order fields. (4) Validation runs before any database operations. - Xeophon (security review)

I found one remaining request-validation crash in the updated TTL parser. The new parse_order_ttl() rejects floats and decimal strings, but it still accepts arbitrary-length digit strings before calling int(value). On current Python, int() raises ValueError once the string exceeds the max digit limit, so an invalid ttl_seconds can still turn POST /api/orders into a 500 instead of the intended JSON 400.

Repro on current head 829d9eeaf027b299d97a8d6c7d2e0c29b15ae7f2:

ttl_seconds = "9" * 4301
parse_order_ttl_huge_exception=ValueError
parse_order_ttl_huge_message=Exceeds the limit (4300) for integer string conversion
POST /api/orders -> status=500, content_type=text/html; charset=utf-8
trace: create_order -> parse_order_ttl -> ttl = int(value)

Validation performed:

git diff --check origin/main...HEAD -- otc-bridge/otc_bridge.py otc-bridge/test_otc_bridge.py tests/test_otc_bridge_query_validation.py
python -B -m py_compile otc-bridge/otc_bridge.py otc-bridge/test_otc_bridge.py tests/test_otc_bridge_query_validation.py

# 5 passed, 25 deselected

Because this PR is specifically hardening malformed order payloads, the huge integer-string path should fail closed with the same {"error": "ttl_seconds must be an integer"} 400 rather than bubbling an exception. A simple guard before int(value) is enough, e.g. reject digit strings longer than the maximum meaningful TTL length, or wrap int(value) in try/except ValueError and return the existing integer error. Please add a regression for a digit string over Python's conversion limit.

Closing — your branch has irreconcilable merge conflicts (week-old, base has moved). Confirmed as first-poster credit-eligible for this fix per Codex forensic audit 2026-05-18 (ZacharyZhang-NY: OTC order JSON/TTL validation (batch 2 Q5 first-poster)). The work is recognized; bounty credit stands.

If you'd like the canonical version of this fix merged from your branch instead of a later submission, rebase and ping — happy to re-evaluate. Otherwise this is closed administratively.
