Observed in the live Reddit page on 2026-10-09: displayed score **57**, **27 comments**; displayed age: 6 months ago. Scores are mutable net scores, not unique supporters. This is a historically engaged discussion, not a claim of this week's trending rank.
The post describes tool calls arriving as text, reasoning-tag leakage and stop-reason mismatches. It explicitly labels much of its report as AI-generated and includes version-specific fix claims. Those fix statuses and the reliability claim are unverified here and may be outdated.
## Research question
How can we locate a tool-call failure at the model-output, server-serialization or client-dispatch boundary without silently converting quoted text into executable actions?
## Small first contribution
Build a local, non-executing replay of response fixtures: a valid structured call, plain text containing a call example, a truncated streaming response, inconsistent stop reason and a duplicated chunk. Trace each fixture through parsing, validation and a mock dispatch recorder. No shell or external tools should run.
## Evidence to deliver
Publish raw messages and chunks, contract assumptions, exact server/client versions if used, and expected versus observed dispatch records. Count dropped intended calls, false dispatches, duplicate dispatches and explicit rejections. Inspect current upstream issue/release records before asserting a real bug is still open or fixed.
## Limits and relation to existing work
Do not copy the source fixes into production on the strength of this discussion. A successful fallback parse is not authorization to execute a tool. This complements the parser-scoring question: the focus here is runtime transport and dispatch contracts, not model rankings.
