+# RustyNES v2.2.1 — Housekeeping patch
+
+A **housekeeping patch** on top of v2.2.0 "Capstone": dev-tooling archival, a zero-source-change dependency consolidation, and a new gitignored FDS test corpus. **Zero accuracy, feature, or core changes** — the deterministic `#![no_std]` chip stack, save-state / TAS / netplay-replay formats, and every golden vector are untouched: **AccuracyCoin holds 141/141 (100.00%)**, unchanged from v2.2.0.
+
+## Added
+
+### Game Genie re-key research tooling archived
+
+Preserved the six intermediate research / verification scripts behind the header-robust Game Genie code re-key (which shipped in #262) beside the generator in `scripts/gg/`: `crc_combine.py` (a pure-Python `zlib.crc32_combine` implementation, self-tested against 2000 random synthetic trials, underpinning the `rom_crc32 == crc32_combine(prgCRC, chrCRC, chrLen)` identity), `alias_resolve.py` (long-tail title-alias CRC resolution), `coverage.py` / `coverage2.py` (name-join coverage accounting), `inspect.py`, and `verify.py` (which now proves the combine identity over every standard nes20db cart dump). Dev / research tooling only — touches no crate, no build, no core.
+
+### 2A03-revision DMA-divergence probe archived
+
+`scripts/probes/probe_rev.rs`, a diagnostic test probe behind the already-shipped v2.1.7 "Stepping" DMA-frontier work (ADR 0033) — snapshot-hashes DMA test ROMs under `Cpu2A03Revision::Rp2A03G` vs `Rp2A03H`. Kept for reference; not wired into CI.
+
+### `TakuikaNinja` FDS hardware-verification probes (gated, gitignored)
+
+Four `RUSTYNES_FDS_BIOS`-gated smoke tests (`crates/rustynes-test-harness/tests/fds_takuikaninja.rs`) against `FDS-Mirroring-Test`, `FDS-4023-Test`, `FDS-Audio-Registers`, and `FDS-4030D1-Addr` — real hardware-verified probes of `$4023` / mirroring / audio-register behavior and the FDS DRAM-refresh-watchdog IRQ. None of the four carries an explicit permissive license, so they're staged gitignored under `tests/roms/external/fds-takuikaninja/` rather than committed, mirroring the existing commercial-ROM convention; every test skips cleanly when the BIOS or a probe disk is absent. The underlying `$4023` and mirroring behaviors these probes exercise are already implemented and unit-tested independently in `crates/rustynes-mappers/src/fds.rs` — this is regression insurance against a second, hardware-verified oracle, not a fix for a gap. The `$4030.D1` DRAM-watchdog probe tracks a known, honest residual (not yet modeled by RustyNES or, per upstream, by most current FDS emulators) — see `docs/accuracy-ledger.md`.
+
+## Changed
+
+### Dependency consolidation (closes Dependabot #298–#303)
+
+Rolled all six open Dependabot bumps into one reviewed change, each verified against the code and gates; all landed with **no source changes** and the deterministic `#![no_std]` core untouched: **pollster 0.4 → 1.0** (frontend / android / iOS `block_on` for wgpu/Metal init), **wide 0.7 → 1.5** (the desktop `u32x8` SIMD blitter — the SIMD-vs-scalar byte-identity gate still passes), **tungstenite + tokio-tungstenite 0.29 → 0.30** (netplay + mobile signaling; `default-features = false` + `handshake` + `rustls-tls-webpki-roots` retained for clean pure-rustls cross-compiles), **bytemuck 1.25.0 → 1.25.1** and **cc 1.2.66 → 1.2.67** (patch), and CI **actions/setup-python v5 → v6** (MkDocs step).
+
+## Notes
+
+- Version: workspace `2.2.0 → 2.2.1`. No mobile app version change (`versionCode`/`versionName` on Android and `MARKETING_VERSION` on iOS stay frozen at their v2.0.x host-only release points; the joint mobile store launch remains v2.3.0).
+- **No accuracy/oracle number moves.** AccuracyCoin 141/141, nestest 0-diff, `blargg_apu_2005` / `pal_apu_tests` (10/10) / `visual_regression` / the 60-ROM commercial oracle all unchanged. Save-state / TAS / netplay-replay formats untouched.
+- Full host gate green: fmt · clippy (all feature combos + wasm32) · rustdoc (`-D warnings`) · `no_std` cross-compile (`thumbv7em`) · markdownlint · `cargo deny check`.
