Scrum-driven fixes: P5-001 auth wired, P42-001 truth evaluator, P9-001 journal on ingest

Apply the highest-confidence findings from the Phase 0→42 forensic sweep
after four scrum-master iterations under the adversarial prompt. Each fix
is independently validated by a later scrum iteration scoring the same
file higher under the same bar.

Code changes
────────────
P5-001 — crates/gateway/src/auth.rs + main.rs
  api_key_auth was marked #[allow(dead_code)] and never wrapped around
  the router, so `[auth] enabled=true` logged a green message and
  enforced nothing. Now wired via from_fn_with_state, with constant-time
  header compare and /health exempted for LB probes.

P42-001 — crates/truth/src/lib.rs
  TruthStore::check() ignored RuleCondition entirely — signature looked
  like enforcement, body returned every action unconditionally. Added
  evaluate(task_class, ctx) that actually walks FieldEquals / FieldEmpty /
  FieldGreater / Always against a serde_json::Value via dot-path lookup.
  check() kept for back-compat. Tests 14 → 24 (10 new exercising real
  pass/fail semantics). serde_json moved to [dependencies].

P9-001 (partial) — crates/ingestd/src/service.rs
  Added Optional<Journal> to IngestState + a journal.record_ingest() call
  on /ingest/file success. Gateway wires it with `journal.clone()` before
  the /journal nest consumes the original. First-ever internal mutation
  journal event verified live (total_events_created 0→1 after probe).

Iter-4 scrum scored these files higher under same prompt:
  ingestd/src/service.rs      3 → 6  (P9-001 visible)
  truth/src/lib.rs            3 → 4  (P42-001 visible)
  gateway/src/auth.rs         3 → 4  (P5-001 visible)
  gateway/src/execution_loop  4 → 6  (indirect)
  storaged/src/federation     3 → 4  (indirect)

Infrastructure additions
────────────────────────
 * tests/real-world/scrum_master_pipeline.ts
   - cloud-first ladder: kimi-k2:1t → deepseek-v3.1:671b → mistral-large-3:675b
     → gpt-oss:120b → devstral-2:123b → qwen3.5:397b (deep final thinker)
   - LH_SCRUM_FORENSIC env: injects SCRUM_FORENSIC_PROMPT.md as adversarial preamble
   - LH_SCRUM_PROPOSAL env: per-iter fix-wave doc override
   - Confidence extraction (markdown + JSON), schema v4 KB rows with:
     verdict, critical_failures_count, verified_components_count,
     missing_components_count, output_format, gradient_tier
   - Model trust profile written per file-accept to data/_kb/model_trust.jsonl
   - Fire-and-forget POST to observer /event so by_source.scrum appears in /stats

 * mcp-server/observer.ts — unchanged in shape, confirmed receiving scrum events

 * ui/ — new Visual Control Plane on :3950
   - Bun.serve with /data/{services,reviews,metrics,trust,overrides,findings,file,refactor_signals,search,logs/:svc,scrum_log}
   - Views: MAP (D3 graph, 5 overlays) / TRACE (per-file iter timeline) /
     TRAJECTORY (refactor signals + reverse index search) / METRICS (explainers
     with SOURCE + GOOD lines) / KB (card grid with tooltips) / CONSOLE (per-service
     journalctl tail, tabs for gateway/sidecar/observer/mcp/ctx7/auditor/langfuse)
   - tryFetch always attempts JSON.parse (fix for observer returning JSON without content-type)
   - renderNodeContext primitive-vs-object guard (fix for gateway /health string)

 * docs/SCRUM_FIX_WAVE.md     — iter-specific scope directing the scrum
 * docs/SCRUM_FORENSIC_PROMPT.md — adversarial audit prompt (verdict/critical/verified schema)
 * docs/SCRUM_LOOP_NOTES.md   — iteration observations + fix-next-loop queue
 * docs/SYSTEM_EVOLUTION_LAYERS.md — Layers 1-10 roadmap (trust profiling, execution DNA, drift sentinel, etc)

Measurements across iterations
──────────────────────────────
 iter 1 (soft prompt, gpt-oss:120b):   mean score 5.00/10
 iter 3 (forensic, kimi-k2:1t):        mean score 3.56/10 (−1.44 — bar raised)
 iter 4 (same bar, post fixes):        mean score 4.00/10 (+0.44 — fixes landed)

 Score movement iter3→iter4: ↑5 ↓1 =12
 21/21 first-attempt accept by kimi-k2:1t in iter 4
 20/21 emitted forensic JSON (richer signal than markdown)
 16 verified_components captured (proof-of-life, new metric)
 Permission Gradient distribution: 0 auto · 16 dry_run · 4 sim · 1 block

 Observer loop: by_source {scrum: 21, langfuse: 1985, phase24_audit: 1}
 v1/usage: 224 requests, 477K tokens, all tracked

Signal classes per file (iter 3 → iter 4):
 CONVERGING:  1 (ingestd/service.rs — fix clearly landed)
 LOOPING:     4 (catalogd/registry, main, queryd/service, vectord/index_registry)
 ORBITING:    1 (truth — novel findings surfacing as surface ones fix)
 PLATEAU:     9 (scores flat with high confidence — diminishing returns)
 MIXED:       6

Loop thesis status
──────────────────
A file's score rises only when the scrum confirms a real fix landed.
No false positives yet across 3 iterations. Fixes applied to 3 files all
raised their independent scores under the same adversarial prompt. Loop
is measurable, not hand-wavy.
