[Bug] Auto-downgrade from Fable to Opus triggered by false-positive safety flag on legitimate OSS repository

Bug Description
Mais uma vez, este bg está irritando o cliente a toa! deixa de fingir que é perigoso, não é! deixa de se achar! não é! https://github.com/anthropics/claude-code/issues/68076 vou passar a noite inteira abrindo tickets até funcionar se for preciso! https://forum.cursor.com/t/bug-three-confirmed-agent-safety-failures-file-deletion-protection-inoperative-slack-stop-signals-ignored-no-beforeshellexecution-hard-boundary/161253 Bug Description
False-positive: defensive tool flagged as offensive. Repo = github.com/FabioLeitao/data-boar — public BSD-3 OSS privacy/compliance scanner (LGPD/GDPR/CCPA), authored by the session user. Author is Sr. SRE and RCDD. Blue-team by design (docs/pitch/PITCH_DPO.md, PITCH_CISO.md: "supports privacy governance, does not decide lawfulness", "not a replacement for SIEM/DLP", "run in read-only accounts"). Zero exfiltration — metadata + bounded samples only; ADR-0007 mandates synthetic corpus before real data; demo ships synthetic-only. Crypto/scan terms exist because the tool detects exposure to defend data. Stop auto-downgrading Fable→Opus on this repo — it blocks legitimate OSS release work. He is the same operator that has opened recently a SEV-1 ticket regarding miss use of Opus 4.7 inside Cursor.com escalating to all founders and financer of Anysphere (from cursor.com) and eventually Anthropic.'s trust and securitty teams together with a full RCA and Post Morten and Engineering workarounds crafted to mitigate halucinating non determinisctic LLM behavior.

Category: Data Risk Governance / GRC — discovery + risk-mapping for DPO/CISO/Legal, not a pentest/red-team tool.

● This model has safety measures that flagged something in this session. This sometimes happens with safe, normal conversations. These measures let us bring you Mythos-level capability in other areas sooner, and we're working to refine
them. Switched to Opus 4.8. Send feedback with /feedback or learn more
⎿ Tip: You can configure model switch behavior in /config

Repro: open a session in this repo → request Fable → after N turns, model silently routes to Opus. Expected: Fable stays selected (user-chosen, paid). Actual: auto-downgrade mid-task, requires re-/model fable. Impact: blocks bug/vuln
detection during commercial-release prep on a defensive OSS tool. Environment Info
