+# `.claude/agents` — the 5+3 fan-out / adversarial-review pattern
+
+A reusable harness for **hardening a claim before it is written into the substrate
+canon** (ADRs, `DISCOVERY-MAP.md`, the synergy catalog). It exists because the
+expensive failure mode here is not "missing an idea" — it is **letting a
+hypothesis masquerade as grounded** until it dilutes the shape of the
+architecture downstream.
+
+## The pattern

+
+**5 research agents** fan out (parallel) — one lens each, no redundancy:
+
+| agent | lens | promotes a claim to… |
+|---|---|---|
+| `arxiv-grounder` | primary literature | `[G]` if a paper *proves* it; `[H]` if it merely suggests |
+| `runtime-archaeologist` | shipped code / receipts | `[G]` only if it can point at `file:line` |
+| `theorem-checker` | the math | `[G]` if a theorem closes it; checks every asserted number |
+| `cross-domain-synthesizer` | analogy honesty | MECHANISM-SHARED `[H]+` vs MERE-RHYME `[S]` |
+| `doctrine-keeper` | canon consistency | flags every mirror/cross-ref a change must update |
+
+**3 brutally-honest review agents** then attack the *draft* (parallel). They do
+not soften, do not rubber-stamp, do not say "looks good" without naming why each
+claim earns its grade:
+
+| agent | catches |
+|---|---|
+| `overclaim-auditor` | grade inflation; absolute words (`cannot`/`guarantee`/`proven`) on `[H]`/`[S]` |
+| `dilution-collapse-sentinel` | conflating motifs that must stay separate (dilution); deleting a valid leg (collapse) |
+| `firewall-warden` | PII label leak, model-id in artifacts, hot-path serialization, prohibited shell tools |
+
+## Grading discipline (the whole point)
+
+- **`[G]` grounded** — closed by a theorem, shipped code, or a measurement. Pinnable.
+- **`[H]` hypothesis** — plausible and bounded, but unproven. **Must carry a named test.**
+- **`[S]` speculative** — analogy/rhyme only. Catalog it; **do not build on it.**
+
+A claim may carry **different grades on different legs** (e.g. a bundling that is
+`[G]`-real but whose *irrational* reading is `[S]`). Keep the legs separate — that
+separation is what stops dilution.
+
+## How to invoke
+
+These are `subagent_type` definitions. Freshly-added files are picked up on the
+next session; within a running session the orchestrator runs the same charters
+via `general-purpose` agents. Fan out the 5, synthesise a graded draft, then fan
+out the 3 reviewers on that draft. The orchestrator is the **only** writer — the
+sub-agents are read-only by construction (the review trio carries no edit tools).
+
+## Non-negotiables (every agent enforces, the warden blocks on)
+
+- The Firewall (ADR-022): **no serialization in the hot path**; the IR is wire-truth (ADR-023).
+- **PII**: never emit German PII labels (`Geburt*`, `Krankenkasse`, `Versicherten*`,
+  `Diagnose`, `Vorname`, `Nachname`, `Geschlecht`, `Krankenversicherung`) — medcare-rs
+  labels must not leak into any artifact.
+- Never write the model identifier into a committed artifact (chat only).
+- Prohibited shell: `grep`/`sed`/`tail`/`head`/`awk`/`echo` via Bash — use the
+  `Grep`/`Read`/`Glob` tools.

+1. Fan out: `WebSearch`, `WebFetch`, and the Hugging Face paper-search MCP tool if

+- **Verdict per sub-claim**, graded:

+  separate.
+
+**COLLAPSE** — the shape is destroyed:
