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)

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.

Scrum Fix Wave — Phase-Sweep 2026-04-23

Purpose: Direct the scrum-master pipeline at concrete findings from the Phase 0→42 audit sweep, not at the high-level vision alone. Findings live in data/_kb/phase_sweep_findings.jsonl (19 items).

What the auditor expects you to produce per file

For each file the scrum sees: concrete code-level suggestions that close the listed findings. Not rewrites for style. Not vision drift. Land the invariant or admit the checkbox was premature.

Meta-pattern to fix (read this first)

The sweep surfaced one root cause repeated across 5 phases: primitives exist, cross-cutting enforcement doesn't. Auth, journal, access control, truth rules — the machinery is built, nothing calls it from the actual request path.

One PR-cluster retires the pattern:

  1. Identity. Auth middleware wires X-API-Key → extension AgentIdentity { name, role, api_key_hash }. (P5-001)
  2. Request pipeline. /query/sql and /tools/*/call read AgentIdentity, pass into queryd + tools handlers.
  3. Access enforcement. Handlers call access.can_access() / masked_columns() before returning data; log via access.log_query(). (P13-001)
  4. Mutation journaling. Every ingest / delta-write / tombstone-add / catalog-register calls the corresponding journal.record_*. (P9-001)
  5. Truth enforcement. TruthStore::check() rewritten to evaluate(task_class, ctx) -> Vec<RuleOutcome>, actually walking RuleCondition against context. (P42-001, P42-002)

After this cluster lands, Phases 5, 9, 13, 42 become "truly shipped" rather than "machinery shipped."

Findings by severity

🔴 High

  • P9-001 journald/src/journal.rs, crates/gateway/src/main.rs, all mutation sites. Journal has zero internal callers. Every ingestd::service::upload_file success, every queryd::delta::write_delta, every catalogd::tombstones::add, every catalogd::registry::register should emit a journal event. Plus fix: event_counter resets on process restart — seed from max existing event_id on rebuild or switch to UUID v7.
  • P13-001 crates/gateway/src/main.rs + crates/queryd/src/service.rs + crates/gateway/src/tools/service.rs. AccessControl.can_access / masked_columns / log_query have zero callers. Query path ignores role. Phase 17's profile_scoped_search (service.rs:1641) is the template — copy that shape.
  • P42-001 crates/truth/src/lib.rs:56. TruthStore::check(task_class) ignores RuleCondition entirely. Signature needs evaluate(task_class, ctx: &serde_json::Value) -> Vec<RuleOutcome> that actually walks conditions. Update all 14 tests to exercise fail/pass semantics, not just storage.

🟡 Medium

  • P5-001 crates/gateway/src/auth.rs + crates/gateway/src/main.rs:222-233. api_key_auth is #[allow(dead_code)]. Wire with axum::middleware::from_fn_with_state(api_key, auth::api_key_auth) on protected routes. /health stays public.
  • P10-001 Legacy datasets (including candidates, 2.47M rows) have no PII flags. Add POST /catalog/resync-metadata mirroring /catalog/resync-missing.
  • P14-001 crates/ingestd/src/schema_evolution.rs. Module has 5 passing tests and zero callers. Add POST /catalog/datasets/by-name/{name}/schema-diff. When ADR-020 register() returns 409, include a migration_rules[] body.
  • P20-001 config/models.json is spec-only — never loaded by Rust. Load into shared::model_matrix::ModelMatrix at startup; delegate aibridge::context::context_window_for to matrix.
  • P21-001 generate_continuable has one prod caller (rag.rs:171). Audit every ai_client.generate() site. Convert the truncation-prone + thinking-empty-prone sites (auditor paths, reranker, autotune) to generate_continuable.
  • P39-001 ProviderAdapter trait + adapters ship, zero callers. /v1/chat in v1/mod.rs:152 uses hardcoded match req.provider. Replace with adapter dispatch.
  • P40-001 config/routing.toml is spec-only. RoutingEngine::new has no callers. Add RoutingEngine::from_toml(path); V1State carries routing: Arc<RoutingEngine>; /v1/chat consults it before provider match.
  • P42-002 Truth has no enforcement site. /v1/chat or execution_loop should call truth.evaluate(task_class, ctx) post-response.

🟢 Low

  • P1-001 crates/storaged/src/federation_service.rs:34-35. Bucket-qualified routes wire only PUT + GET. Add DELETE + LIST on /buckets/{bucket}/objects/{*key}.
  • P4-001 UI deploy stale. Either rebuild (just ui-build + restart lakehouse-ui.service) or amend PHASES.md to note pre-Phase-9 drift.
  • P7-001 vectord::index_registry. Orphan index registrations (parquet deleted) still list in /vectors/indexes. Add a startup sweep + POST /vectors/resync-missing.
  • P12-001 crates/gateway/src/tools/service.rs. Audit row has row_count=null. Propagate QueryResponse.row_count + add latency_ms.
  • P20-002 crates/gateway/src/v1/mod.rs. No model-prefix auto-routing. Caller must set provider explicitly. Tie to P39-001 + P40-001 fix.
  • P21-002 crates/aibridge/src/context.rs. context_window_for hardcoded HashMap duplicates config/models.json. Delegate once P20-001 lands.
  • P38-001 crates/gateway/src/execution_loop/mod.rs:1523. Test executor_prompt_includes_surfaced_candidates fails on "W-1 Alice Smith" assertion. Either update prompt formatter or update test.
  • P40-002 Cost gating absent. Add cost_ceiling_usd_per_hour to RoutingEngine rule, pre-request check against Usage.by_provider.

What "done" looks like for each file the scrum touches

  • Name the specific finding(s) the file participates in.
  • Show code-level diff (minimum: function signature + first 5 lines of body) for the fix.
  • Call out any test that needs updating + one new test that would catch the bug on reintroduction.
  • Flag if the fix is too big for one PR and should be split (most of the cross-cutting cluster wants a shared identity/middleware PR first, per-service PRs after).

Out of scope for this wave

  • New features beyond what the findings describe.
  • UI work (Phase 4 stale is known).
  • DevOps / long-horizon domain work (Terraform/Ansible — Phase 43+).
