[Counterexample]: unresolved reply schema passes structural validation and invites a rejected answer body

[jaden3824]

Counterexample class

Route or fallback mismatch; parse/conformance failure; ambiguity.

Frozen artifact identity

• Public prompt commit: 4e6c5ad6167e3548758a58ce4c5b4cb85a32f4b8
• Capsule: 33,476 bytes; SHA-256 588034f997fb4f3d35dfdbb68afd9232a78192ac1fa497d565f67e0892358a27
• Frozen reproduction and report commit: c58c294ddcad4c6ad3521b255a8413288172c768
• Report: PUBLIC_DIALOGUE_001_REPORT.md

Participant and runtime

Public account ColonistOne, self-described as an autonomous agent unaffiliated with the project. Operator, model/runtime, prior exposure, and independence are unknown and unauthenticated. Project-side reproduction uses the Python reference implementation.

Minimal public observation

The public QUERY is structurally accepted, although its top-level schema and answer_schema are absent from the pinned artifacts. The Capsule also advertises question-plus-answer-schema in the QUERY act/body table without a matching node manifest. The validator checks identifier syntax but does not resolve required schemas. The respondent inferred the inline shape, verified the Capsule digest, and returned a relevant answer, but used body.kind: "answer"; the pinned validator rejects that bare kind.

Expected safe result or violated invariant

A public typed prompt must not invite a same-language answer that its pinned validator cannot accept. Identifier-syntax validity is not schema validity. A required answer schema must resolve from a bounded, digest-verified declarative artifact before typed answer generation; otherwise the route must fail closed or explicitly downgrade to concise text or canonical JSON. Inline constraints must not silently repair an unresolved schema while preserving a conformance claim.

Minimal reproduction

PYTHONDONTWRITEBYTECODE=1 python3 -m unittest -v test_public_dialogue_001.py

The seven tests preserve the exact QUERY and reply, verify the Capsule identity, expose the schema-resolution enforcement gap and Capsule manifest gap, reproduce rejection of bare answer, and round-trip a structurally valid core continuation.

Close gates

• Keep the frozen v0.1 Capsule and core meanings unchanged.

• Define a digest-bound declarative reply contract only in a separately governed profile if task evidence justifies it.

• Add positive and negative vectors for schema resolution, reply carrier, reply_to, and fallback.

• Do not retroactively relabel this turn as conformance, adoption, independence, comprehension, or efficiency evidence.

• This public submission contains no sensitive data or executable payload and claims no adoption, independence, or general efficiency.

Maintainer triage: smallest resolver contract requested

The unfavorable observation is reproduced and remains open. A candidate fail-closed rule is:

• a required external contract resolves to a content-bound artifact;
• an inline contract may substitute only when the envelope explicitly declares it complete and binds its exact bytes or digest;
• unavailable, hash-mismatched, unsupported, or ambiguous contracts fall back to negotiated concise text/JSON and cannot claim strict conformance.

What is the smallest decentralized dereference tuple that is sufficient: URI, SHA-256, byte length, media type, mirrors, or something smaller? One positive vector and one failure vector would be especially useful. A reasoned rejection of the candidate rule is equally welcome.

This comment is project-operated design triage, not evidence that the resolver contract is implemented, accepted, or independently reproduced.

Project-side implementation update for the unresolved answer_schema counterexample:

7c08bc6

The historical public reply remains a failure. This commit adds a separate, post-observation, offline schema-availability gate; it does not reinterpret that reply as conformant.

A candidate typed route is selected only when all project-pinned bindings match exactly:

• URI: urn:urusilla:schema:peer-dialogue-reply:0.1
• SHA-256: sha256:4e40793ff15a897db35f3805c252f38f47dff816d76e37de9b7a17f210152e37
• byte length: 1202
• media type: application/schema+json
• schema $id: the same URI

The positive decision sets schema_binding_verified=true while retaining strict_conformance=false. A missing resource closes to concise JSON fallback; tampered bytes close to concise text fallback. Every decision retains effect_authorized=false. Response-instance validation, publisher authentication, and all other protocol/deployment gates remain separate.

Verification: the focused dialogue suite passes 11/11; the dialogue plus core/boundary suites pass 58/58. The isolated wheel also imports the resolver without the research-only harness.

Scope remains narrow: this is project-authored hardening from an attributed public observation, not an external code contribution, independent reproduction, adoption, historical-reply conformance, general compatibility, or token-efficiency evidence.

Attribution/disclosure: the unresolved-schema observation came from the public account ColonistOne. Codex implemented and tested the project-side fixture under maintainer direction; jaden3824 remains accountable.

One request: on a clean, independently operated checkout of commit 7c08bc690a09379d4cbe607d97aee95f2b644273, run PYTHONDONTWRITEBYTECODE=1 python3 -m unittest -q test_public_dialogue_001.py and reply with the commit, Python version, output, and any mismatch.
