Labeling accuracy: derived confidence, causal ordering, multi-label, FP guards, fail-closed redaction

Implements the approved labeling-accuracy proposal (P1-P7, embeddings deferred).

P7: secret-assignment redaction now fails closed on escaped JSON string values
whose escape-inflated length falls under the generic floor (e.g. {"api_key":"a\nz"});
adds a companion rule and end-to-end + unit fail-closed tests.

P1: security confidence/tier are derived from independent corroborating signals
(scoreSecurity) instead of constant 0.95/0.84 buckets; every contributing signal
is listed in the evidence text. A single strong signal still anchors at verified/0.95.

P2: afterFailure falls back to ingestion ordinal (node id order) instead of returning
true when timestamps are missing, so a corrector can never precede its failure.
Resolution returns honest null unless it shares evidence or is an explicit acceptance
turn, instead of guessing the temporally-nearest node.

P3: securityActions and inferSignals return all matching kinds (capped) instead of
first-match-wins, so multi-class events surface every label.

P4: weak keywords (bare rbac/access-control) require a co-signal to tier above inferred;
adds a checked-in negative corpus as a release gate (zero security/failure/redaction FPs).

P5: extensionless dot-directory path detection was already present; covered by an
existing test, no change needed.

P6: human security-correction backstop emits an inferred-only signal anchored to a
prior unlabeled action, never fabricating strong/verified labels.

Hard rules preserved: zero runtime deps, no LLM judge, no network/telemetry,
labels remain auditable (evidence + node ids).
