# Ripple Log — Cycle 1 (2026-05-14 re-verification)

> **Source trigger**: `_docs/02_document/05_drift_findings_2026-05-14.md` — targeted re-verification of `Auth/JwtExtensions.cs`, `Program.cs`, `Infrastructure/ConfigurationResolver.cs`, `Infrastructure/CorsConfigurationValidator.cs`, `Database/DatabaseMigrator.cs`, `Services/AircraftService.cs`, `Services/FlightService.cs`, `Services/WaypointService.cs`.
> **Mode**: `document` skill in **Task mode** (re-run on previously "complete" docs). The drift was discovered AFTER the initial pass declared `current_step: complete`; this cycle is a targeted refresh.

## Files in the changed-source set (cycle trigger)

These code files are the **observed-current-state** that the docs were re-aligned against. None of them were modified during this documentation cycle — code stays as-is; only the docs change.

| Source file | Why it triggered ripple |
|-------------|--------------------------|
| `Auth/JwtExtensions.cs` | ECDSA-SHA256 + JWKS + iss/aud (was HS256 + shared-secret in docs) |
| `Program.cs` | Calls `ResolveRequiredOrThrow` + `CorsConfigurationValidator.EnsureSafeForEnvironment` (was hardcoded dev fallbacks in docs) |
| `Infrastructure/ConfigurationResolver.cs` | New file, no module doc previously existed |
| `Infrastructure/CorsConfigurationValidator.cs` | New file, no module doc previously existed |
| `Database/DatabaseMigrator.cs` | `TIMESTAMP` (not `TIMESTAMPTZ`); explicit `REFERENCES` on every FK; `DEFAULT` on every non-nullable non-key column |
| `Services/AircraftService.cs` | Case-INSENSITIVE name filter + `OrderBy(Name)` (docs said case-sensitive + no ordering) |
| `Services/FlightService.cs` | Case-INSENSITIVE name filter + `OrderByDescending(CreatedDate)` (docs didn't specify) |
| `Services/WaypointService.cs` | Composite `(missionId, waypointId)` predicate collapses two error cases into one 404 |

## Doc updates in this cycle

Direct updates driven by the drift findings:

| `_docs/02_document/04_verification_log.md` | Re-issued § 3 F5 + F6 rows; demoted § 4.2 F3 CORS-unconditional; added § 4.3 |
| `_docs/00_problem/problem.md` | "What is", "Problem", "Users", "How it works", "Cross-cutting contracts" sections |
| `_docs/00_problem/restrictions.md` | E1, E3, E4, E9 — 4 env vars, no fallback, gated CORS |
| `_docs/00_problem/acceptance_criteria.md` | AC-1.5, AC-1.6, AC-2.3, AC-2.8, AC-4.2, AC-5 entire group (rewrite), AC-6.1, AC-6.2, AC-6.4, AC-6.5, AC-6.11, AC-6.12, AC-9.1 |
| `_docs/00_problem/security_approach.md` | § 1 (full rewrite), § 2 (FL claim semantics), § 3 (secrets), § 5 (CORS), § 6 (footguns), § 7 (audit) untouched, § 8 (threat model), § 9 (refs) |
| `_docs/00_problem/input_data/data_parameters.md` | § 1 env vars (4 required), § 2.1 / § 2.2 query case sensitivity, § 3 schema (TIMESTAMP, REFERENCES, DEFAULT) |
| `_docs/01_solution/solution.md` | Topology paragraph, component table rows 05 + 07, § 2.2 ADR-005 row, § 3.3 JWT scenario, § 5.1 + § 5.2 references |

## Import-graph ripple (computed, not provided by trigger)

Two new C# files were introduced under `Infrastructure/`:

- `Infrastructure/ConfigurationResolver.cs` (`Azaion.Flights.Infrastructure.ConfigurationResolver`)
- `Infrastructure/CorsConfigurationValidator.cs` (`Azaion.Flights.Infrastructure.CorsConfigurationValidator`)

Reverse-dependency scan (`rg "ConfigurationResolver|CorsConfigurationValidator"` in C# sources) finds **only `Program.cs` consumes them today**. No additional components are reached transitively. Both files belong to component `07_host` (composition root); they did NOT warrant a new component — the host doc was extended to cover them.

The JWT changes in `Auth/JwtExtensions.cs` (`Azaion.Flights.Auth.JwtExtensions`) are consumed only by `Program.cs`. The downstream `ClaimsPrincipal` is consumed by every `[Authorize(Policy="FL")]` controller, but the **wire-shape contract** of those controllers is unchanged — the policy still requires `permissions=FL`, the policy name is still `"FL"`. No component doc refresh needed beyond `05_identity` + `07_host`.

The DB schema changes (`TIMESTAMP`, `REFERENCES`, `DEFAULT`) ripple to:

- `_docs/02_document/data_model.md` (already in the direct list) — ERD + invariants.
- `_docs/00_problem/input_data/data_parameters.md` (already in the direct list) — § 3 schema tables.
- `_docs/00_problem/acceptance_criteria.md` AC-2.8 (already in the direct list) — TOCTOU mitigation via FK error 23503.

No further out-of-list ripple discovered.

## Verdict

All ripple-traced docs are included in the direct update list above; the import-graph scan surfaced no new candidates not already covered. The remaining suite-level docs (`../suite/_docs/05_identity*.md`, `../suite/_docs/00_roles_permissions.md`) likely carry correlated drift on the JWT model but are **out of scope** for this repo's `/autodev` cycle and are flagged in `04_verification_log.md` § 4.3 for the next suite-level autodev run.

## State at end of cycle

- All Phase 1 (doc revisions) tasks from `05_drift_findings_2026-05-14.md` are complete.
- Phase 2 (test-spec re-issue) is queued — next sub-skill invocation: `test-spec` in cycle-update mode.
- Phase 3 (resume Step 4) is the autodev step transition after Phase 2 lands.
- `_docs/02_document/state.json` is updated to record the re-verification entry.
- `_docs/_autodev_state.md` advances `sub_step` from `targeted-reverification-needed` → `complete`, then Step 1 → Step 2 (Plan) per the existing-code flow auto-chain.
