preferConfiguredHostedTools collected every stripped additional_tools container index into a Set and spread it into Math.min to find the first one. A request carrying enough additional_tools containers exceeds the function argument-count limit and throws RangeError, so an attacker-sized request aborts request normalization. Indices arrive in increasing order during the map, so the first stripped index is already the minimum; track it directly.

Assert the restored request body.
Line 57 only verifies that buildRequest does not throw. The test also passes if hosted image_generation restoration is removed or occurs in container index 1 or 2. Capture the result from buildRequest and assert that exactly one hosted declaration is restored in container index 0, with no restoration in indices 1 and 2.
The implementation explicitly restores the declaration in the first stripped container.

…rdered freeform wrapper gap (#5203) * fix(responses): avoid spreading stripped tool indices into Math.min preferConfiguredHostedTools collected the index of every stripped additional_tools container into a Set and spread it into Math.min to find the first one. The set size is request-controlled, so a body carrying enough additional_tools containers exceeds the engine argument-count limit and throws RangeError, aborting request normalization before dispatch.

Carried from #5132. Co-authored-by: luvs01 <27862058+luvs01@users.noreply.github.com> * fix(grok): reject unsafe protobuf response lengths The reset-coupon decoders trusted provider-controlled varints and length prefixes. decodeVarint accumulated with a 32-bit bitwise shift, so a six-byte varint could set the sign bit and return a NEGATIVE length; the length-delimited branches then did offset += bytesRead + len and moved the cursor BACKWARDS, which is a non-terminating loop on a hostile or corrupt gRPC-web body rather than merely a wrong value. A truncated varint returned its partial accumulation, and a declared length past the end silently produced a short subarray. decodeVarint now validates the offset, accumulates by multiplication so the value cannot wrap, throws once a part leaves the safe-integer range, and throws on a varint with no terminator instead of returning a partial value. It also enforces the ten-byte protobuf varint limit explicitly, because the safe-integer guard cannot stand in for a length bound: a continuation byte with no payload bits contributes a part of zero, which is a safe integer, so an arbitrarily long run of 0x80 decoded as a valid zero and an overlong zero length normalized a malformed body into an empty coupon list. The new decodeLength bounds every wire-type-2 field inside its enclosing message, and all three branches route through it. This turns a malformed response into a thrown error where it previously returned partially decoded coupons. Both callers in src/server/management/grok-coupon-routes.ts already wrap getGrokRemainingResets in try/catch and answer 502, and a new case asserts the throw at that boundary rather than only at the decoder, so the endpoint reports the upstream failure instead of acting on a tokenId recovered from garbage. Wire types 1 and 5 still stop iteration rather than throwing; that pre-existing silent drop is unchanged. Carried from #5150. Co-authored-by: luvs01 <27862058+luvs01@users.noreply.github.com> * fix(devin): preserve reasoning signature association assistantThinking concatenated every thinking block and independently picked the last available signature, so one block text rode ChatMessagePrompt field 11 paired with a different block signature at field 12. Cognition validates field 12 against the thinking it attests, so that pairing is an invalid replay. The blocks that reach this point are separately signed by construction: src/responses/parser.ts merges CONSECUTIVE unsigned reasoning parts into one, so more than one surviving text-bearing block means more than one real attestation. The pair is now only formed when it is real. Every block with text is still replayed at field 11, and field 12 is attached only when the text replayed IS the text that signature attests, which is the single-block case. Several independently signed blocks send the joined chain unsigned. Keeping only the final block instead would trade an invalid pairing for silently discarding reasoning the turn produced, which the history replay this function exists for cannot afford. A signature-only block, which the parser emits for an encrypted-only reasoning item, contributes neither text nor signature; the turn-dropping guard in mapOneMessage already keyed on reasoning.thinking, so no assistant turn changes its drop decision. The parser also parks a JSON.stringify of the whole reasoning item in the signature field of an UNSIGNED thinking part so the opaque item survives a same-provider round trip. That dump is provider state, not an attestation, and it was reaching field 12 verbatim. isProviderIssuedThinkingSignature now denies exactly that shape, and it lives in src/responses/reasoning-envelope.ts beside the representation it describes rather than as a private copy in one adapter. It stays a deny-list: field 12 is opaque, so an allow-list modelled on the base64 spelling of an Anthropic signature would drop a JWT-shaped or JSON-shaped token the service really issued. A counter-case test pins that those survive. Carried from #5140. Co-authored-by: luvs01 <27862058+luvs01@users.noreply.github.com> * fix(responses): recognize reordered and escaped freeform wrapper keys The progressive decoder located a wrapper by comparing the buffer against the literal opening for each key it knew. unwrapFreeformToolInput decides the COMPLETED input with JSON.parse, which cares about neither property order nor how a name is spelled, so two spellings of the same wrapper matched nothing at all: {"metadata":1,"input":"cmd"} and a canonical key written with a \\u0069 escape both streamed the raw object as deltas and then completed as cmd. The routed path hid this behind its own hold for unrecognized objects; the direct Responses bridge published the wrapper syntax that completion then removed. This is the third spelling of the disagreement #5047 and #5129 closed for compact and whitespace wrappers. The prefix is now scanned as JSON instead of matched as text, in a new src/responses/freeform-wrapper-scan.ts. It answers only which wrapper the completed text will unwrap to: an own input with a string value streams progressively, because completion gives it precedence over everything else in the object whatever its position; an input with a non-string value, a text that is not an object, and an object JSON.parse can no longer accept publish their own bytes, because that is what completion returns for them; every other object holds until it parses, because a key that has not arrived can still change the answer. Property names are decoded with JSON.parse rather than by hand, since a second decoder beside it is how this defect arose. That last rule narrows the direct bridge and the narrowing is deliberate. A parseable object that is not a wrapper now arrives in one delta when it closes, where it used to stream as it was generated. No prefix of it can be published safely, because input can still follow any property, and routed restoration has held exactly these bodies since #5047 — this is the two paths agreeing rather than a new restriction on one. Bodies that are not objects, which is what an exec program or a patch envelope looks like, are unaffected. structure/transports/responses.md states the cost rather than repeating the old claim that raw input is always progressive, and the bridge test comment that asserted the old timing is corrected. Holding every undecided object subsumes the fallback keys, which only unwrap as the single string field and so are decidable by no prefix. freeformFallbackKeys existed solely to let the streaming side hold them and is removed with its last caller. Containers are walked with an explicit stack, not recursion, because the value being skipped is provider-controlled. Classification is clamped to MAX_FREEFORM_WRAPPER_SCAN_CHARS, and the release parse runs only where the scan actually SAW the object close. Every other hold stays held: an incomplete object has nothing to parse, and re-reading a budget-exhausted buffer on every delta whose last character happens to be a brace is quadratic work for a delta that would arrive in the same instant as the authoritative completion behind it. The previous code parsed the whole buffer on every delta once a fallback wrapper was committed. Duplicate input keys and wrappers that turn invalid after a valid prefix was published remain the same bounded exceptions, now asserted through a reordered wrapper as well. The regression records the deltas a caller would receive and also the values the decoder PROPOSED that do not extend what was already published: both callers drop those, so a test that only mirrored the callers would stay green while the decoder proposed a retraction. It asserts liveness too, so satisfying agreement by holding everything fails, and it pins that an oversized value full of braces publishes nothing. Closes #5151. --------- Co-authored-by: lidge-jun <lidge-jun@users.noreply.github.com> Co-authored-by: luvs01 <27862058+luvs01@users.noreply.github.com>
