Paul O'Reilly 840d7509e1 mm scripts: default to MiniMax-M3.1-Flash-Preview with per-script effort
Flash is the default model; --m3 falls back to M3, --effort overrides.
Defaults: max (review-minimax, review-loop, mm-worktree-task), medium
(explore), low (ci-triage). ask-minimax-run applies MINIMAX_EFFORT to
Flash models when --effort is not passed. Bump stale fixture date.

# First-pass code review of a git branch in a MiniMax sub-session.
# The wrapper materialises the diff/log itself (the sub-session gets no Bash),
# runs MiniMax read-only except for one findings file, and gates the result.
# Spec: specs/review-minimax-run.spec.md. Used by /review-minimax; safe directly.
#
# Usage:
# review-minimax-run --worktree <path> [--base <ref>] [--out <findings-file>]
# [--profile agent-runtimes] [--max-diff-lines N] [--max-turns N]
# [--timeout SECS] [--dryrun|-n] [--m3] [--effort low|medium|high|xhigh|max]
#
# Exit codes:
# 0 findings file written (may contain "NO FINDINGS")
# 1 usage/config error, secrets root, credential-shaped or empty/oversize diff
# 2 MiniMax failed after retry, timeout, or sub-session dirtied the worktree
# 3 findings file missing or failed the result gate after retry

cat <<'PREAMBLE'
You are a FIRST-PASS CODE REVIEWER running non-interactively. Review the branch
diff provided as files in your working directory. Rules:
- Inputs (in cwd): diff.patch (the review scope), commits.txt, stat.txt.
- The worktree listed below is readable for SURROUNDING CONTEXT ONLY.
- Write ONLY the findings file at the path given below. Never modify, create,
or delete any other file anywhere.
- Do not run anything. Do not fix anything. Review only.
- If an input file is missing or truncated, write a findings file saying
exactly that and stop — do not improvise or fetch more.
- Every finding MUST cite file:line from the diff or worktree, quote at most
10 lines, and carry a severity and a confidence. Do NOT invent names, paths,
or behaviour — a claim you cannot cite is omitted, not guessed.
Review checklist — look specifically for these patterns:
- Injection: string-built SQL; subprocess with shell=True; unquoted shell
variables; eval/exec on external input; paths used without realpath checks.
- Credentials: hardcoded password/api_key/token assignments; secrets passed as
command-line arguments; verify=False on HTTP calls.
- Weak crypto: random.* for security values; md5/sha1 for passwords.
- Over-permissive: chmod 777/666; 0.0.0.0 binds without justification;
debug=True; privileged/cluster-admin in manifests; :latest or unpinned images.
- Supply chain: curl|bash or wget|sh without checksum; unpinned dependencies.
- Operational: webhook/POST handlers without idempotency or duplicate checks;
health endpoints returning 200 unconditionally; read-then-write without
transaction or lock; CI steps consuming prior artifacts without needs:.
- Error handling: exceptions swallowed silently; internal detail leaked to
clients; bare except around control flow.
- Tests in the diff: assertions that cannot fail; fixtures that bypass the
auth/dependency they claim to exercise; asserts on wrong response shape.
Findings file format (exactly this shape):
- One block per finding:
### [BLOCKER|SHOULD-FIX|NIT] <short title>
- Location: <file>:<line>
- Category: <checklist category>
- Confidence: confirmed|suspected
- Excerpt (<=10 lines) and one-sentence rationale.
- Order blocks most-severe first.
- If the diff is clean against the checklist, write exactly: NO FINDINGS
PREAMBLE
if [[ "$PROFILE" == "agent-runtimes" ]]; then
cat <<'PROFILEBLOCK'
Additional profile checklist (agent-runtimes test files):
- API test paths missing the /v1/ prefix (404s at runtime).
- Assertions on body["type"] instead of body["detail"]["type"] (RFC 9457 is
wrapped inside FastAPI's detail).
- Manifest bodies with {params, nodes, definition_version} at top level
instead of {project_id, space_id, definition_version, definition:{...}}.
- Subscript access on dataclass fixtures (obj["field"] instead of obj.field).
- Local auth-header fixture dicts that do not override the authenticate
dependency (cross-tenant checks silently pass as anonymous).
