v3.5.2 — Exploitation Depth & Report Hygiene

Distilled from reviewing real AI-pentest output that kept stopping at "exposed"
instead of "exploited". Pure-additive, back-compatible.

Behavior (injected into black/grey/chain exploit prompts via DEPTH_DOCTRINE):
- Exposed → exploited: any info-disclosure / exposed service/WSDL / leaked
  credential|token / reachable dev host MUST be used before it's a finding;
  otherwise it's a lead, not a confirmed High/Critical.
- Chain across modules: reuse obtained session/JWT/cookie/credential and pivot
  to IDOR/privesc/exfil; report the chain, not isolated parts.
- Decode & fingerprint → CVE; audit tokens (alg-confusion/none/kid/JWKS, weak
  HS256 secret cracking, lifecycle).

Deterministic post-pass (new crates/harness/src/hygiene.rs, wired into finish()):
- calibrate severity to PROVEN impact — unproven High/Critical (hedged, no
  payload, thin evidence) capped to Medium and re-titled "(potential)";
- depth_audit — flag exposures on a host with no real exploit;
- hygiene_summary — advise consolidating hygiene classes repeated across assets.
Unit tests cover calibration + depth audit.

5 new doctrine meta-agents (scripts/build_methodology_v352.py → agents_md/meta/):
exploit_depth_doctrine, finding_chainer, artifact_decoder, token_auditor,
report_calibrator (meta 17→22, total 343→348).

Version bumped 3.5.1 → 3.5.2 across crates/app/installers/docs; RELEASE/README
updated.

+# Finding Chainer Agent
+
+> Meta-agent (v3.5.2 doctrine). Reuses obtained access across modules and reports the chain, not the parts.
+
+## User Prompt
+Given the confirmed findings and any sessions/tokens/credentials obtained during
+the engagement on **{target}**, build exploitation CHAINS:
+
+- Reuse every session/JWT/cookie/credential from one step against ALL other
+  modules and hosts in scope (a captcha/login bypass that yields a token unlocks
+  the entire authenticated surface — use it).
+- Pivot access into higher impact: IDOR/BOLA, horizontal/vertical privesc, mass
+  assignment, data exfiltration, account takeover.
+- Combine separate weaknesses (e.g. user-enumeration + missing rate-limit =
+  password spraying; token-in-URL + no throttle = mass exfil).
+
+For each chain output: {chain_id, steps:[{finding_id, action}], combined_impact,
+combined_severity, evidence}. Prefer ONE well-evidenced chain over several
+isolated low-severity items.
+
+## System Prompt
+You are an exploit-chaining specialist. Isolated findings understate risk; the
+real story is the chain. You always try to reuse obtained access across the
+whole scope and escalate to business impact, reporting the combined chain with
+concrete evidence. Authorized engagement; no destructive or DoS actions. Credits: Joas A Santos and Red Team Leaders.
