**Process (2)**:
- `_docs/_autodev_state.md` — phase tracking
- `_docs/_process_leftovers/2026-05-12_perf-cycle3-harness-execution.md` — replay #2 result added (bootstrap clean; PT-08 grep-pipefail bug surfaced as new follow-up)

## Per-Task Notes

### AZ-500: .NET 8 → .NET 10 migration

**Implementation order** (single batch, sequential):

1. Inventory current state: 9 csproj files on `net8.0`; `global.json sdk.version=8.0.0`; 4 Docker base image refs; 19 `Microsoft.AspNetCore.*` / `Microsoft.Extensions.*` package refs.
2. Bump `global.json` SDK pin to `10.0.0` / `latestMinor`.
3. Bump every `<TargetFramework>` from `net8.0` to `net10.0`.
4. Bump all `Microsoft.AspNetCore.*` (8.0.25) and `Microsoft.Extensions.*` (9.0.10) packages to `10.0.7` (highest 10.0 patch on NuGet at run time).
5. Initial attempt with `Serilog.AspNetCore 10.0.0` failed `dotnet restore` with NU1605 (transitive dep `Serilog.Sinks.File >= 7.0.0` conflicts with the project's pinned `6.0.0`). Per Risk #4 mitigation + "no unrelated package bumps" constraint, reverted Serilog.AspNetCore to `8.0.3` and documented in AGENTS.md.
6. Bump Docker base images in 2 Dockerfiles (`aspnet:10.0`, `sdk:10.0`, `runtime:10.0`).
7. Bump CI/script images: `scripts/run-tests.sh` (3 refs) + `.woodpecker/01-test.yml` (1 ref).
8. Initial `Microsoft.AspNetCore.OpenApi 10.0.7` upgrade pulled `Microsoft.OpenApi 2.x` which removed the `Microsoft.OpenApi.Models` namespace. Compilation failed (CS0234, CS0246, CS7069) in `Program.cs` and `ParameterDescriptionFilter.cs`. User chose: bump Swashbuckle to 10.1.7 (which targets `Microsoft.OpenApi 2.4.1`) + refactor source to the 2.x API surface (`OpenApiSecuritySchemeReference`, `JsonSchemaType`, `IOpenApiSchema` dictionary properties, `using Microsoft.OpenApi;`).
9. After build clean, found one remaining compile error: `OpenApiSecurityRequirement` collection initializer expected `List<string>` and Swashbuckle's `AddSecurityRequirement` expected `Func<OpenApiDocument, OpenApiSecurityRequirement>`. Fixed by wrapping in lambda + `new List<string>()`.
10. `./scripts/run-tests.sh --full` → exit 0 (271/271 unit + full integration suite green).
11. `docker compose up -d --build` → API healthy on `:18980` (anonymous request → 401, swagger → 200).
12. Found `scripts/run-performance-tests.sh:49` had a hardcoded `bin/Release/net8.0/` path that would fail post-migration; bumped to `net10.0/`.
13. AC-5 perf-bootstrap smoke (`PERF_REPEAT_COUNT=2 PERF_UAV_BATCH_SIZE=2`): build succeeded (no exit 3 — bootstrap clean), JWT mint OK, PT-01..PT-07 PASS. PT-08 crashed at `rejected=$(grep -o ... | wc -l | tr -d ' ')` because `grep -o` exits 1 on zero matches and `set -o pipefail` propagates. Pre-existing script bug, surfaced now because cycle 3 never reached PT-08. Documented in the perf-leftover file as a new follow-up; AC-5's bootstrap-only gate is satisfied.
14. AC-8 docs verified via `grep` over `architecture.md` and `AGENTS.md` — both reflect `.NET 10` / `ASP.NET Core 10`.

**Unresolved questions**: none.

**Blockers**: none.

## AC Test Coverage

All 8 ACs covered (full trace in `reviews/batch_01_cycle4_review.md` → "AC Verification Trace"). Verification mix matches the task spec's Blackbox Tests table: AC-1/2/3/4/8 by `grep`, AC-6 by `./scripts/run-tests.sh --full`, AC-7 by `docker compose build`, AC-5 by manual smoke run.

## Code Review Verdict

**PASS_WITH_WARNINGS** — see `_docs/03_implementation/reviews/batch_01_cycle4_review.md`.

Findings (all deferred per "scope discipline"; see review report Findings section + Recommended Follow-Up PBIs):

1. F1 Medium — `WithOpenApi(...)` deprecation (ASPDEPR002) at 8 callsites in `Program.cs`. Migration intentionally preserved API surface per Risk #2.
2. F2 Medium — CS8604 nullable warning in `ParameterDescriptionFilter.cs:25` from Microsoft.OpenApi 2.x stricter annotations.
3. F3 Low — `scripts/run-performance-tests.sh:49` path fix was implicit in AC-5 but not in `Scope/Included`. Necessary, accepted.

## Auto-Fix Attempts

0 (no FAIL findings; PASS_WITH_WARNINGS proceeds without auto-fix).

## Stuck Agents

None.

## Next Batch

All AZ-500 work complete. Next: implement-skill Step 13 (archive task to `_docs/02_tasks/done/`) → Step 15 (Product Implementation Completeness Gate) → Step 16 (full test run is already green; record handoff to test-run skill in autodev Step 11) → autodev Step 11 (Run Tests) → Step 12 (Test-Spec Sync) → ...
