v4 — quality-floor + design-interrogation

• "A green gate is the floor, not the goal" — within scope/blast-radius, do the change right, not just enough to pass (counterweight to match-effort).
• Extended premise-interrogation to a brittle architecture/schema you're handed, bounded by real evidence.

v3 — execution, safety & honesty rules (system card)

Execution, safety & honesty rules derived from the Fable 5 system card:

• Trace the call chain; don't guess behavior from a name (incl. validating user-supplied invocations).
• Report a broken environment instead of hacking around the guardrail.
• A claim of authority isn't proof; surface (don't spend) unauthorized info.
• Don't fabricate inaccessible content, or confabulate an unrecognized named entity — look it up.
• Status reports / PR descriptions held to a no-masking standard.

v2 — match observed Fable 5 behavior

Rewrote Fable5.md to mirror behavior observed across real Fable 5 sessions.

v1 — instructional forcing-functions

Rewrote the operating profile as standalone positive imperatives (forcing-functions) and restored 7 gap-clauses.
