v26.1-Alpha.6 — Mute semantics + audit log

BCDebugJavaAgent v26.1-Alpha.6

Pre-Release — Alpha builds are functional but unstable. Do not run in production environments.

Highlights

Mute semantics for filter removal — a removed prefix now goes SILENT:

• MethodRecorder gains a muted-prefix set: already-instrumented methods
  keep calling into the recorder, but entries for muted prefixes are no
  longer recorded (exit paths self-heal via missing stats entries).
  POST /filters?remove=X mutes X; re-adding unmutes. No byte surgery —
  hot-path cost is a small startsWith scan, zero when the set is empty.
• setFilters responses now include the muted list.

Control-plane audit log:

• Every mutation (/log-level, /filters, /hooks/reload) appends a
  structured JSONL record — {ts, op, detail} — to
  <outputDir>/bcdebug-audit.log. Best-effort by design: audit failures
  never affect the audited operation or the game.

Validation

Live on MC 1.21.1 dedicated server (obfuscated, mappings auto):

add dcd    -> {"added":1,"retransformed":1,"muted":[]}
remove dcd -> {"removed":1,"muted":["dcd"]}
re-add dcd -> {"added":1,"muted":[]}          (recording resumes)
AUDIT: 3 JSONL records captured (filters ×3)

54 unit tests green (mute/resume/isolation + audit wiring).
