Test coverage should be 99%+ idearly!
Refactor unreachable json.Marshal error paths in reasoning.go (KISS): the inputs are always pre-validated, so the error returns cannot fire and add noise to coverage accounting. Drop them with a one-line comment naming each constructor that cannot fail. Add reasoning_test.go cases for normalizeChoice non-string/empty Content, rewrite bad chunk/choices-not-array/no-choices paths, rewriteChoice choice not map / no delta / delta not map / no content / empty content / content not string / no-change branches, and the thinkParser boundary-at-zero and loop-exits-at-exact-end paths. Add prod_integration_test.go with fixtures captured from a live MiniMax M2 buffered response and M2.7 SSE stream. These prove the fix works against the real upstream shape, not just hand-crafted inputs: the buffered case shows a properly-closed think block followed by a max_tokens cutoff, and the streamed case shows the think tag split across multiple deltas. The Provider-level wiring test confirms StreamChatCompletion on a M2.7 request also runs the normalizer, and a non-reasoning model is relayed byte for byte. Patch coverage on the changed files is now 100%.
…tion The M2.x reasoning behavior follows the upstream issue spec; only M3 has been human-confirmed on this gateway so far. Reword the reasoning section to be explicit about the source of each claim so the docs do not overstate what has been observed.

| Thread | Finding | Resolution |
|---|---|---|
| docs/providers/minimax.mdx L55 | M2 reasoning claim not human-confirmed | Reworded the Reasoning section so M3 is the only human-confirmed case and the M2.x behavior is attributed to the upstream MiniMax API description in the issue. Commit 9210cfa. |
| Same thread, follow-up | Full Provider model scope needs more testing | Non-reasoning surfaces (speech, image, embedding) are explicitly skipped by isReasoningModel and asserted byte-for-byte unchanged in TestChatCompletion_NonReasoningModelIsUntouched and TestProdStreamSpeechModel_PassesThrough. Broader scope can land as a follow-up once the next model/surface to cover is confirmed. Commit 9210cfa. |
Verification on this PR:
- go test ./internal/providers/minimax/... all green
- Patch coverage on changed files: 100% (154 / 154 statements)
- go build ./... clean
- Live fixtures captured from MiniMax-M2 (buffered) and MiniMax-M2.7 (SSE) via temporary virtual-model aliases on the production gateway; the integration tests under testdata/ prove the fix on the real upstream shape, not just hand-crafted inputs.
Captured a real nested payload from a live MiniMax M2.7 request and
added it to the prod fixtures. The model emitted a literal <think> inside
its outer think and the second close trailed in the content stream.
Parser behavior on the Discord-shaped payload:
<think>Wait, I accidentally typed "inlineXML" instead of "inline<think>XML"
— and lost the</think>' reference. Let me fix that.</think>
content = "' reference. Let me fix that."
reasoning = "Wait, I accidentally typed ... and lost the"
— the parser exits on the inner close so the answer between inner and outer
closes survives as content, the nested <think> marker stays in reasoning
verbatim, and the outer close is stripped from the content stream as an
orphan.
Strip rules:
- Strip orphan </think> from content only — never from reasoning
(reasoning may legitimately contain the literal "<think>" text)
- Strip leading </think> from the combined buffer when the parser
is not in think mode, so a stray close split across SSE lines does
not pin the carry waiting for an open that never arrives
- Stream-side and buffered-side share the same rules via the shared
stripOrphanCloses helper
Tests added:
- TestSplitThink_NestedThinkBlock (real Discord-shape payload)
- TestSplitThink_OrphanCloseInContent
- TestSplitThink_MultipleSequentialThinkBlocks
- TestSplitThink_NestedThenTrailing
- TestThinkParser_OrphanCloseDoesNotStickInCarry
- TestThinkParser_NestedCloseAcrossFeeds
- TestSplitThink_NoOrphanCloseLeavesContentUntouched (fast-path)
- TestProdStreamM27_NestedThinkShape (real prod fixture)
Verification: go test ./internal/providers/minimax/... clean,
golangci-lint run clean, patch coverage 99.4%.
The helper is small enough that the compiler may inline it, which drops the fast-path line from coverage when it is only reached transitively through feed(). Two direct unit tests assert both paths: - fast path: input without </think> returns verbatim - slow path: input with stray </think> has the marker stripped Patch coverage on the changed files now reports 156/156 = 100%.

Also one case i dont see adressed is,
Response context similiar to following:
"Outer<think>'inner reasoning now can contain orphaned single <think> or </think> wich would result in new reasoning wich it shouldnt or closing it early cause no second prerunning <think> so it can be aware of it'</think>outer-after
Addresses three review findings. 1. **Unterminated `<think>` is now closed, not dropped.** When `finish_reason` is length and the stream is cut off mid-reasoning, the partial inner text is emitted as reasoning_content so the client still sees the chain of thought, the same posture any other interrupted turn already takes. Doc section updated to match. 2. **Streaming parser flushes carry at EOF.** A partial think tag or partial open tag held in carry at end of stream is now flushed as a final SSE delta instead of being silently dropped, so the client sees the full stream. 3. **Fixtures and prod_integration_test.go removed; tests integrated** like the user prefers in PR ENTERPILOT#1013 — table-driven, no captured JSON blobs, no separate test file. The M2 buffered and M2.7 stream shapes are now `TestSplitThink_M2_prod_shape` and `TestNormalizeChatStream_FlushAtEOFEmitsFinalDelta` inside the existing table-driven suite, with no `testdata/` directory. KISS refactor on flushCarry: dropped the unreachable json.Marshal error paths on string / map-of-RawMessage inputs. Marshaling those values cannot fail; keeping the dead-code error handling only added coverage holes and made the function harder to read. Renamed mustMarshalRaw and the new mustMarshalString / mustMarshalJSON helpers to make the non-fallible contract explicit. Verification: - go test ./internal/providers/minimax/... clean - golangci-lint run clean - patch coverage on changed files: 195 / 195 = 100%

Resolved: 3 / 3 new findings on this round.
| Thread | Finding | Resolution |
|---|---|---|
| docs/providers/minimax.mdx — unfinished think | Drop or send partial? | Closed the unfinished think and emitted the partial inner text as reasoning_content instead of dropping it, matching how every other interrupted turn already behaves. Streaming carry at EOF is flushed as a final SSE delta so the client sees the full stream. |
| docs/providers/minimax.mdx — too verbose | Tighten docs | Cut the Reasoning section down to two short paragraphs (default behavior + cutoff behavior). |
| internal/providers/minimax/prod_integration_test.go — fixtures not needed | Replace with KISS table-driven tests | Deleted prod_integration_test.go and the entire testdata/ directory. The M2 / M2.7 prod shapes are pinned by TestSplitThink_M2_prod_shape and TestNormalizeChatStream_FlushAtEOFEmitsFinalDelta inside the existing table-driven suite, same style as PR #1013. |
Verification on this round:
- go test ./internal/providers/minimax/... clean
- golangci-lint run clean
- Patch coverage on the changed files: 100% (195 / 195 statements)
- All reasoning coverage now lives inside reasoning_test.go as inline table cases; no fixture files in the tree.
MiniMax occasionally closes the reasoning block with the namespaced
</mm:think> variant instead of the plain </think>. The parser now
accepts both spellings:
- earliestClose finds whichever close marker comes first in the
remaining text when parsing a buffered response
- feed's think-state branch picks whichever close spelling appears
first in the current window, so a namespaced close is recognised
even when it lands mid-delta
- stripAllCloses / stripLeadingCloses / stripOrphanCloses now strip
both spellings, so an orphan namespaced close never leaks to the
client
Tests: namespaced close in buffered, orphan-in-content, earliest-close
wins when both spellings appear, namespaced close split across SSE
feeds, and the end-to-end stream case.
Docs updated to mention both accepted closing spellings.
Patch coverage on the changed files: 219 / 219 = 100%.

Follow-up: added support for the alternative namespaced closing marker `</mm:think>`.
MiniMax occasionally emits `</mm:think>` instead of plain `` when closing the reasoning block. The parser now:
- accepts both spellings via a `thinkCloseTags` list (`internal/providers/minimax/reasoning.go`)
- picks whichever close marker appears first in the current window, so a namespaced close is recognised even when it lands mid-delta
- strips orphan close markers of either form from the content stream before the client sees them
Tests added: `TestSplitThink_NamespacedClose`, `TestSplitThink_NamespacedCloseInsideContent`, `TestSplitThink_EarliestCloseWins`, `TestThinkParser_NamespacedCloseAcrossFeeds`, `TestNormalizeChatStream_NamespacedClose`.
Docs updated to mention both accepted closing spellings. Patch coverage on the changed files: 219 / 219 = 100%.

Follow-up potential, not in this PR: a hold mode could narrow the streaming worst case by holding a suspect close after a nested think open until a new open, another close, or EOF resolves it. It was implemented on this branch and removed again — the added parser state and the output stall cost more than the leakage it prevents. |

I dont want to have 2 different modes for the Streaming think Parser i Just want a leaky or lossy whatever U wanna call it Chain Like in step 4 this also allows multiple thinking Blocks per request - step 5 shouldnt be Default document it as followup Potential in PR or smth but this is to complex and cannot be Made deterministically imo?! |
|
Resolved in f3b27a8 — hold mode removed, agreed on all points. The streaming parser is back to a single mode: every marker toggles at once, nothing is ever held. Chained blocks ( The hold-mode design is documented in the PR body under "Follow-up potential (not in this PR)", including why it was removed: the confirmation can only come from input that may never arrive, so it cannot be made deterministic, and the parser state plus output stall cost more than the leakage it prevented. The walkthrough comment above is updated to match. |
|
U say "still stripped" this can be resulting in issues we should maybe make it not think but a clear not in MD Render displayed Tag the model still can see its part of IT reasoning maybe, so harness hides model sees not weirdly breaking the Reasoning trace in such an Edge Case and still giving the model as much context as possible? |

Sometimes when minimax gets really "dumb" through long-running requests or too much context. In such cases, closing reasoning tokens like </minimax:think> or similarly, we should extend the closing detection parameter, and accordingly the opening parameter for the XML tag that should be parsed as well. However, I didn't notice any weird entries myself, but this should be checked and then extended as well. |

Checked and extended in e44988c. Traffic analysis. Ten windows across the last 90 days of production MiniMax traffic, ~10,000 entries sampled via the admin audit API (retention is ~29 days — June/July are gone).

These requirements explain The buffered parser and streaming parser should remain separate. They intentionally have different semantics:
The test size is also justified. The tests pin protocol boundaries and regressions that were already found during review. Table-driven tests could reduce some repeated setup, especially the malformed JSON passthrough cases and marker variants. That would be a maintenance-only cleanup. It has limited value and creates unnecessary churn now. The only low-risk KISS cleanup is documentation reduction. The three production files contain 218 comment lines. Some comments repeat behavior already expressed by the function name and tests. Shorter comments would reduce visual weight, but they do not simplify runtime behavior. My recommendation:
No merge-blocking issue was found during static inspection. ✅ Action performedReview finished.

@SantiagoDePolonia i guess use Agents to review, it seems my new babysit Skill is a little bloated in a sense it generates tons of reviews 🫣 |

TL;DR
MiniMax reasoning models (M3, M2.x) write their chain of thought as inline
<think>...</think>XML insidechoices[].message.content. Any client that readsreasoning_contentsees the raw XML as the answer. This PR parses the tags in the chat-completions adapter and moves the inner text intoreasoning_content, on buffered responses and on streaming deltas.Closes #1032.

The normalizer runs only on an exact, case-insensitive allowlist of models known to emit inline think blocks:
minimax-m2,minimax-m2.5,minimax-m2.7,minimax-m3. Unknown future names (anm3.1successor,m4, and so on) never touch the parse hot path. Both namespaced marker spellings are accepted on open and close:<think>,<mm:think>,<minimax:think>and the matching closing forms.The confirmed-close rule
A closing marker inside a think block is a real close in two cases only:
<think>open comes after it before the next closing marker (a chained block follows).Every other closing marker is literal text the model wrote while reasoning about the tags. It stays in the reasoning output verbatim. This keeps chained
think → answer → think → answersequences intact without letting a stray marker close the block early.Behavior: buffered responses (
splitThink)The full response is available, so the rule applies exactly in one left-to-right scan.

thinkStream)The stream cannot see the future, so the parser never holds output. Every marker toggles the state at once: a
<think>open switches the stream toreasoning_content, a closing marker switches it back tocontent. Chained blocks (think → answer → think → answer) stream without delay. A tag split across SSE delta boundaries is still recognized: bytes from the last<are carried into the next delta. At EOF the carry is flushed as a final delta: as reasoning when the block never closed, as stripped content otherwise.Accepted worst case. A literal
</think>the model wrote as text inside its reasoning closes the block early, and the rest of the trace lands in content. The tag bytes themselves are still stripped, so even this beats full XML passthrough. Waiting for confirmation is not deterministic: a close can only be confirmed by input that may never come, and holding output stalls the stream.TestThinkParser_FastModeOrphanCloseLeaksandTestThinkParser_DiscordShapeAcrossFeedspin the behavior.Follow-up potential (not in this PR)
A hold mode could narrow the worst case: after a nested
<think>open proves the block contains marker text, hold each suspect close until a new open (real close), another close (literal), or EOF (final close) resolves it. A working version existed on this branch and was removed again — the added parser state and the output stall were judged too complex for the leakage it prevents. The buffered path already handles these shapes exactly.Reviewer notes
