Conversation
… RC pair The maintainer added a fifth audit to v2.9.2 (2026-09-27): one AI-written report covering both repositories, 32 findings AUD-01..AUD-32 (20 in the oracle, 12 in the MiSTer sibling). It was supplied at docs/full-audit-report.md and is moved, byte-identical (md5 0d61e815483f4d96737c9648781e61f2), to docs/audits/v2.9.2-full-audit-report.md, the place the maintainer's 2026-09-22 decision puts every audit. Like the v2.9.0 re-audit reports it is exempt from markdownlint so it is never edited; it passes the linter today anyway. - to-dos/plans/v2.9.2-candidate-plan.md: the line plan's v2.9.2 (the release-candidate .rbf pair and the board session) plus the audit. The RTL findings change the design, so they land before the pair is cut. The gate is stated per item: every AUD row gets a verdict with evidence; a FIXED row needs a red-first test and a caught mutation; the oracle's test-roms, AccuracyCoin 144/144 and nestest hold; the RTL ladder, seed sweep and double compiles run on the final design; performance-shaped rows need the ab_check evidence rule or are behaviour-free by construction. - Known before triage: AUD-04 (the dead NMI detector) is already decided for v3.0.0 by ADR 0042; AUD-21 (arbiter lost write) covers the path v2.8.4 reworked; AUD-17 was declined on #562 as unmeasured and is re-examined. - Blocked here and recorded as such: the board strands A-F need the maintainer at the SuperStation One; the Swift changes (AUD-10, AUD-14) cannot be compiled on this machine and join the v2.9.3 device checklist. - docs/audits/v2.9.2-full-audit-disposition.md: the ledger, one PENDING row per finding, generated from the report's own master table so the IDs and claims match it exactly.

…fer at load Three of the v2.9.2 full audit's six libretro findings (AUD-15..20) were acted on; three were closed without a change. Ledger: docs/audits/v2.9.2-full-audit-disposition.md. AUD-16 -- memory maps at retro_deinit (defence in depth). The report's premise is wrong: libretro.h:3923 says retro_unload_game is "Called before retro_deinit", and RetroArch honours it. But on_deinit already caters for a frontend that skips unload -- it still writes the FDS disk and drops the console -- and on that path it freed WRAM/SRAM/CIRAM while the frontend still held SET_MEMORY_MAPS descriptors pointing into them. A new withdraw_memory_maps(cb), gated on memory_maps_registered, now runs from both on_unload_game (unchanged behaviour) and on_deinit, before the drop. After a normal unload the flag is already clear, so a conforming frontend sees no extra environment call. Red: abi_tests::deinit_without_unload_withdraws_the_memory_maps left 3 descriptors registered. It also asserts that unload followed by deinit makes zero further SET_MEMORY_MAPS calls (new MAP_SETS counter in the harness). Mutants: dropping the deinit call (3 left), ignoring the flag (1 extra call) -- both caught. AUD-17 -- serialize_buffer sized at load. The sizing snapshot used a throwaway Vec, so the first retro_serialize -- the first run-ahead or rollback frame -- grew serialize_buffer from nothing (~260 KB; ~645 KB for a Vs. cabinet). The new size_serialize_buffer() snapshots INTO serialize_buffer with the same encoder on_serialize calls (snapshot_core_into / VsDualSystem::snapshot_into), so serialize_size is unchanged, and reserves SAVE_STATE_DEVICE_HEADROOM for a single console so a Zapper attached later does not reallocate either. This is allocation placement, not a speed claim; no bench reaches it. Red: no_serialize_reallocates_the_buffer_sized_at_load (the first serialize grew it; counted by a #[cfg(test)] SERIALIZE_BUFFER_GROWTHS in on_serialize, following the INJECT_PANIC_IN_RUN precedent). Mutants: a throwaway Vec for a single console and for a cabinet, and shrink_to_fit, all caught. Dropping the reserve alone is NOT caught -- Vec's amortised growth already leaves more than the 26 bytes of slack the Zapper needs -- so the reserve is kept as the guarantee rather than relied on by accident. AUD-19 -- compose_dual no longer zero-fills 491,520 bytes per frame. The scanline loop writes all four bytes of 256 pixels in both halves of all 240 rows, so every byte is rewritten; the buffer is now resized only when its length is wrong (`!=` rather than the report's `<`, which also handles an oversized buffer). compose_dual_overwrites_every_byte_whatever_the_buffer_held compares against an independently built image from stale 0xAA bytes, a wrong-length single-console frame and an empty buffer. As an equivalence test it has no red; skipping the last row and not writing the X byte are both caught. Unmeasured: ab_check.sh cannot reach the Vs. path (as L-2.6), so this is recorded as removal of provably dead work, not a measured gain. Closed without a change: - AUD-15 REFUTED. disk_image_label has no unwinding panic: side_label is total (pinned at 0, 25, 26, 255, 256, u32::MAX by side_label_is_total_at_its_edges), format! of a char/u32 cannot fail, len-1 is guarded. The only reachable panic! is inside rust-libretro's own extern "C" trampoline, which aborts at its own boundary where no outer catch_unwind could reach it. - AUD-18 DECLINED. The bitwise form equals the current nes_buttons on all 65,536 inputs, but rustc 1.96 at -O3 already emits the same 8-instruction branch-free sequence for the current code (--emit asm, no jumps). Zero codegen gain for a tie to two external bit layouts. - AUD-20 NOT A DEFECT, duplicate of L-3.2: the buildbot builds with cargo --target from .gitlab-ci.yml and never reads the Makefile's platform table; `make -n platform=unix RUST_TARGET=aarch64-unknown-linux-gnu` already prints the right cross build. Verified: cargo test -p rustynes-libretro 43 passed (39 + 4 new) on the merged tree; the two libretro harness audits 10 passed; clippy and cargo doc clean.

…ped reads latch
Three of the v2.9.2 full audit's core findings, each pinned by a test that
failed first and a mutation of the fix that the test catches. AUD-05 is
declined. Ledger: docs/audits/v2.9.2-full-audit-disposition.md.
AUD-02 -- Konami VRC2/4/6/7 save states dropped cartridge RAM. The .rns
container carries cartridge RAM only inside the mapper's own MAP blob
(bus.rs), and mappers 21-26 and 85 left their 8 KiB of $6000-$7FFF PRG-RAM out
of it, plus their 8 KiB of CHR-RAM on a board without CHR-ROM. Every state
load, rewind step, run-ahead frame and netplay rollback therefore kept the
RUNNING game's RAM. Each blob now appends a RAM tail after every older field:
VRC2/VRC4 section v2, VRC6 v3 (strict on length, after its 23-byte audio
tail), VRC7 v3 without `mapper-audio` and v4 with it -- two numbers so the
synthesizer tail's presence stays encoded in the version, as v1/v2 already
did; on v4 the OPLL restore is bounded to its own bytes. Older versions load
and leave the RAM untouched; a truncated tail is rejected. VRC7's version
comment claimed v1 carried PRG-RAM; it carried only the enable bit, and the
comment is corrected. VRC3 (73) already serialized its RAM; VRC1 (75) has no
PRG-RAM.
Red: nes.rs vrc_boards_snapshot_carries_prg_ram / _chr_ram (whole machine:
fill, snapshot, zero, restore, compare) -- "mapper 21: PRG-RAM not restored
from the snapshot". Mutants: dropping VRC4's prg_ram copy and VRC7's CHR
copy, both caught. States grow by 8 KiB (16 KiB with CHR-RAM); still plain
byte copies, so determinism holds.
The sweep that found this also found the same gap on mapper 10 PRG-RAM and
on CHR-RAM for 9, 10, 11, 19, 34, 69, 75 and 151. docs/mappers.md lists them
as open; they are fixed in a following commit.
AUD-01 -- FDS saved_sides wraps on 32-bit. The OOM half of the report is false
(nothing allocates from the count), and 64-bit is unaffected: u32::MAX * 65500
is ~2.8e14 and the exact-length check rejects the blob. On wasm32, armv7 and
i686 usize is 32 bits, and 65500 = 4 x 16375, so a count of 2^30 wraps the
side region to 0 bytes: a blob with NO side data passes the length check and
the restore slices past its end. The length is now checked_mul + checked_add
and an overflow is MapperError::Invalid. The report's 16-side cap is not
taken: the blob's own length bounds the count exactly, and a raw .fds has no
side limit.
Red on the NDK i686-linux-android target (static, run under unshare because
bionic's 32-bit pthread refuses pids > 65535): debug "attempt to multiply
with overflow" at fds.rs:2051, release "range end index 106615 out of range
for slice of length 41129". The host fuzz target could never see this. Test
load_state_rejects_a_side_count_whose_length_wraps_on_32_bit (2^30, 2^30+1,
3*2^30, u32::MAX); mutant caught on i686 release; i686 FDS 70/70.
AUD-03 -- an unmapped $4020-$FFFF read skipped the internal data bus. nesdev
Open_bus_behavior ("whatever was left to float") and APU $4015 bit 5 ("from
the last cycle that did not read $4015") put that value on the CPU's internal
latch. The undecoded $4000-$401F arm already fell through to the common tail;
only the cartridge arm returned early. They differ only after something drove
the external bus alone -- a DMC DMA fetch, or an OAM-DMA put while the 6502 bus
is parked in $4000-$401F -- which oam_dma_read_reg_active can then expose. The
arm now yields open_bus and falls through; the Game Genie is still not applied
to unmapped reads.
Red: an_unmapped_cartridge_read_latches_the_floating_value_onto_the_internal_bus
(left 0, right 32); restoring the early return is caught.
NOTE for the sibling: this moves the oracle past its current pin (47f848c),
so the next ORACLE_COMMIT move must re-run VERIFY and the internal-bus gates.
AUD-05 DECLINED: the zero-allocation drain exists (drain_audio_into); the
remaining drain_all callers are the UniFFI by-value return (MOB-06) and wasm;
IMP-07 already adopted; no ab_check workload reaches it.
Verified on the fixed code: AccuracyCoin 144/144, nestest 0-diff, harness
--features test-roms --release 433 passed / 0 failed, rustynes-mappers lib
785/0 (760/0 without mapper-audio), rustynes-core 218/0, thumbv7em no_std
build, cargo doc -D warnings; workspace clippy clean on the merged tree.

…pads, SOCD
Nine of the v2.9.2 full audit's findings (AUD-06..14). All are real. Seven
are pinned by a test that failed first; AUD-12 has no host test (a JNI entry
point feeding a wgpu surface), and the Swift halves of AUD-10 and AUD-14 are
UNCOMPILED on this machine and join the device checklist
(docs/mobile-v2.7.4-device-checklist.md, new rows A13-A15 and I16-I19, run at
v2.9.3). Ledger: docs/audits/v2.9.2-full-audit-disposition.md.
AUD-06 (Critical) -- a peer could size the session's tables. Both the Input and
Checksum arms of session.rs `ingest` called ensure_frame(frame) on the remote
frame unchecked, growing six per-frame vectors: frame = u32::MAX asks for ~4G
entries each, an OOM abort on 64-bit and a usize overflow on wasm32. New
MAX_SESSION_FRAME_LOOKAHEAD = 1024 and max_accepted_frame(): current +
input_delay + max_rollback_frames + 1024, saturating; a larger frame is dropped
before any table is touched. Why it is safe: a peer's newest input is at most
current + our delay + its rollback + its delay + 2 (14 frames with defaults),
checksums are only sent for confirmed frames, the config is not negotiated on
the wire (hence the slack, matching the spectator's existing bound), and
inputs are resent until acknowledged. A hostile peer can now force ~115 KiB.
Red: len 200001 vs bound 1036; the edge test got 1036, expected 1035.
Mutants: Input guard, Checksum guard, `>` -> `>=` -- all caught. The
determinism suites over lossy links pass.
AUD-13 -- signaling ghost slots. add_to_room re-pointed client_room and left
the client in the old room's slots; re-joining took a second slot. join and
quick-match now call a new leave_room first, the same path disconnect takes,
so the old room's peers get PeerLeft and an emptied room is dropped (the
report's patch never told them). 2 red tests, 2 mutants caught.
AUD-07 -- gamepad disconnect. Disconnected fell through `_ => {}`, leaving the
pad's buttons and stick held on the console and its port taken. The report is
half right on exhaustion: gilrs reuses an id only for the same UUID, so it
takes four DISTINCT pads coming and going. PadAssignment::release clears
buttons and stick and frees the port; an unknown pad is a no-op.
PadAssignment is keyed by usize::from(GamepadId) because gilrs cannot build an
id in a test. 3 red tests, 4 mutants caught.
AUD-08 / AUD-09 / AUD-10 -- opposing directions cancel (neutral SOCD). A real
NES D-pad cannot press Up+Down or Left+Right; keyboards, hitboxes, two fingers
on a touch pad can, and games glitch on it. Desktop: input::socd_neutral on
InputState::player() and again in App::frame_inputs after the on-screen pad,
touch and the browser Gamepad API are folded in; opt-out [input]
allow_opposing_directions (Settings -> Input). Movie playback, TAStudio, Lua
and netplay peers' input are NEVER cleaned, so recordings replay as written.
Android: socdNeutral on the combined touch mask (SocdTest.kt red 2/3, then
green under :app:testFossDebugUnitTest, which CI does not run). iOS: the
report's patch cleaned inside hitTest, a no-op since one point cannot produce
opposites; it is applied to the touch union in MultiTouchControlPad.recompute.
Desktop: 3 red tests, all 256 masks covered, 6 mutants caught.
THIS IS A DEFAULT-ON BEHAVIOUR CHANGE and so collides with the project's
off-by-default rule; the default is flagged for the maintainer's decision in
the ledger and the PR rather than decided here.
AUD-11 -- composite_hd_frame ran outside the v2.7.4 panic containment, every
frame, over user-supplied HD-pack data: a panic was a Swift `try!` abort. Its
body moved to composite_hd_locked (the #[uniffi::export] impl rejects
associated functions) and runs under contained_frame with an empty-Vec
fallback, which both hosts already treat as "show the stock picture". Red via
the existing injected_frame_fault hook; removing the containment is caught.
AUD-12 -- nativeSetIndexFrame allocated 120 KiB per frame. Real, but on the
Rust native heap, so the report's "JVM GC churn" framing is wrong. A reused
index_buf filled through get_region, mirroring nativeRender; a wrong length or
a JNI error still drops the frame. cargo ndk arm64 + x86_64 release-mobile
build green; no host test exists for this path (checklist A14).
AUD-14 -- iOS turbo on a 30 Hz wall-clock Timer pulsed while paused and
drifted in display-link bursts. It now flips every two console frames through
a new EmulatorCore.onFrameWillRun hook (the same main thread the gamepad
manager runs on), wired in AppModel.openGame. Uncompiled (I17-I18).
Verified: fmt; clippy workspace + scripting + retroachievements + full, both
wasm32 invocations; cargo doc -D warnings for netplay/frontend/mobile/android;
netplay lib 87 + determinism 16, frontend 615, mobile 39, all 0 failed; Android
gradle unit tests BUILD SUCCESSFUL.

Follows AUD-02 (the previous core commit), which fixed Konami VRC2/4/6/7. The sweep that found that gap found the same one on other boards; this closes them and replaces the VRC-only tests with one that walks every board. Mechanism. The .rns container carries cartridge RAM only inside each mapper's own MAP blob. Mapper 10 (MMC4) left its 8 KiB of $6000-$7FFF PRG-RAM out of the blob -- the battery RAM of Fire Emblem and Fire Emblem Gaiden (both mapper 10, battery=true in the game DB). Mappers 9 (MMC2), 10, 11 (Color Dreams), 19 (Namco 163), 34 (BNROM / NINA-001; every BNROM board has CHR-RAM, e.g. Deadly Towers), 69 (FME-7), 75 (VRC1) and 151 (Konami VS) left out their 8 KiB of CHR-RAM when the cartridge has no CHR-ROM. On every state load, rewind step, run-ahead frame and netplay rollback, the running game's RAM survived instead of the saved one. The standing test. nes.rs every_board_snapshot_carries_cartridge_ram walks every mapper id 0-4095 that the cartridge parser builds -- NES 2.0 under all 16 submappers plus iNES 1.0 for 0-255, each with and without CHR-ROM, retrying other PRG/CHR sizes when a board refuses the first image. For each board it fills the RAM with a pattern, snapshots the whole Nes, overwrites the RAM with its complement, restores, and compares. PRG-RAM is checked through sram(), or through the $6000-$7FFF window where a board keeps RAM without exposing it (only mapper 56). CHR-RAM is checked through PPU $0000-$1FFF, with all writes before the snapshot so the MMC2/MMC4 CHR latches cannot fake a failure. Nothing is skipped silently. An id that never builds must be listed in SWEEP_UNBUILDABLE with a reason; the list is empty, since all 174 supported ids build. The test also asserts that the VRC and fixed boards are among those checked, so a broken probe cannot pass by checking nothing. Coverage: 37 boards through sram(), 1 through the window, 138 for CHR-RAM, 33 with no reachable RAM. About 7 s. Blind spots, documented in the test and docs/mappers.md: RAM behind a board-specific enable that sram() does not expose, and CHR-RAM beyond the 8 KiB mapped at power-on. FDS and NSF do not come through the parser; their save_state already carries their RAM. Red, measured before any fix -- exactly the expected set: mapper 10 PrgSram, and ChrRam for 9, 10, 11, 19, 34, 69, 75, 151: 8192 of 8192 bytes differ in each. Fix, the AUD-02 pattern. A versioned RAM tail is appended after every older field: MMC2, MMC4 (PRG-RAM then CHR-RAM), Color Dreams, 34 and VRC1/151 go to section v2, FME-7 to v3 (after the 5B audio tail), N163 to v4. Older versions load and leave the RAM untouched; a new-version blob of the wrong length is rejected before any field is written. Plain byte copies, with no allocation on load. Each fixed board has round-trip, old-version and truncation tests. Two existing tests that hard-coded a version byte (FME-7, N163) now use the constant. Mutations (remove the loader's copy line, run the sweep, restore from a snapshot): MMC4 PRG-RAM, 34, 69 and 19 CHR -- all caught, with "8192 of 8192 bytes differ". Verified: fmt; workspace clippy clean on the merged tree; the sweep passes; rustynes-mappers lib 807 passed (822 including integration suites), 782 without mapper-audio; rustynes-core 217; thumbv7em no_std build; cargo doc -D warnings; AccuracyCoin 144/144; nestest; harness save_state + snapshot_schema_audit 17 passed. The cargo-fuzz save_state target was not run. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_014qfTKi2M3swo7qnwvYCkDj
…vidence The ledger (docs/audits/v2.9.2-full-audit-disposition.md) goes from 32 PENDING rows to 33 decided ones -- the 32 findings plus AUD-02b, the nine-board save-state RAM gap that AUD-02's sweep found and the report never named. Each row cites the red test or gate, the mutation that was caught, and the commit in the repository that carries the change (oracle or sibling). Tally: FIXED 19 (including AUD-02b; AUD-12 has no host test, and the Swift halves of AUD-10 and AUD-14 are uncompiled and join the v2.9.3 device checklist); REFUTED 4, plus AUD-27 (comment refuted, aspect not a defect); NOT A DEFECT 4; DECLINED 3 (AUD-05, 18, 29); DEFERRED 2 (AUD-04 to v3.0.0 by the maintainer; AUD-28 to the board session as bring-up row O4). Two rows carry a decision that is the maintainer's, not this change's: AUD-08 and AUD-09 made opposing-direction cancel (neutral SOCD) the DEFAULT on desktop and Android. That is a behaviour change, and it collides with the off-by-default rule, so it is marked "default pending maintainer". The README gains the calibration of this fifth report, measured the way the first four were. It read the Rust well: 16 of 20 real, though often with the wrong framing (a 32-bit-only overflow sold as an OOM, native-heap allocation sold as GC churn, a spec claim libretro.h contradicts). It read the RTL poorly: 3 of 12 real, one of them a design defect (AUD-24).

Review comments at @crates/rustynes-mobile/src/lib.rs:
- Around line 1348-1360: Update the power-cycle test to assert that
composite_hd_frame produces nonempty HD output after the machine thaws,
alongside the existing frame assertion.
Review comments at @crates/rustynes-netplay/src/session.rs:
- Around line 463-467: Update max_accepted_frame and the associated resend
policy so inputs remain available until acknowledged across the full negotiated
delay asymmetry; do not rely on the fixed MAX_SESSION_FRAME_LOOKAHEAD window.
Alternatively, negotiate and enforce a supported input-delay bound that
guarantees the resend window covers every accepted but unacknowledged input.
Review comments at @docs/apu-2a03.md:
- Around line 328-329: Update the internal-bus latching description to state
that CPU reads other than $4015 update the latch, matching the exception in
LockstepBus::raw_cpu_read; leave the description of CPU writes unchanged.
Review comments at @docs/audits/v2.9.2-full-audit-disposition.md:
- Line 27: Update the verdicts for AUD-09, AUD-10, AUD-14, and AUD-32 in the
audit disposition: mark a row FIXED only when it names a gate that fails on
main, passes on the branch, and catches a mutation; otherwise record an accurate
non-FIXED verdict with the required owner and target. Leave AUD-12 and AUD-19
unchanged.
Review comments at @docs/libretro/architecture.md:
- Around line 83-84: Update the serialization sizing descriptions to distinguish
single-console and dual-system behavior: in docs/libretro/architecture.md,
qualify expansion-device headroom as applying to single consoles; in
docs/libretro/implementation_specifics.md, document that single consoles reserve
headroom while dual systems report the snapshot’s exact length without headroom.
Review comments at @ios/RustyNES/MultiTouchControlPad.swift:
- Around line 423-426: Update AppModel.pushInput(port:) to combine touchMask and
padMasks[0] into one NesButtonMask, apply cancelOpposingDirections() to the
combined mask, and pass its cleaned bits to emulator.setButtons for port 0.

… docs, ledger) Copilot, CodeRabbit and CodeQL on #563. Four findings were real and are fixed; one was not a defect; the CodeQL alerts were false positives, answered by a rename. iOS turbo pacing (Copilot, real). EmulatorCore.tick called onFrameWillRun before tickNetplay, but npAdvanceFrame can return producedFrame == false while connecting or time-sync stalled, so a stalled session still flipped the turbo phase: pacing drifted from the rollback frame stream it was meant to follow. Whether a netplay tick produces a frame is only known after the call, so on that path the phase now advances AFTER a produced frame and is latched by the next one. The single-player path is unchanged (runFrame always produces one). Uncompiled here, like the rest of the Swift: device checklist I17-I18. Combined-mask SOCD (CodeRabbit, real). AUD-09/10 cleaned only the touch pad's own union, so a touch direction plus the opposite on a hardware pad or keyboard still reached the core -- the desktop cleans the combined mask per player. Android applyPort (every port) and p1Mask (netplay's local input) now pass through socdNeutral; iOS AppModel.pushInput cleans the combined NesButtonMask for every port. `:app:testFossDebugUnitTest` passes. Ledger (CodeRabbit, real). The plan defines FIXED as red, green and a caught mutation. AUD-10 and AUD-14 cannot meet that on this machine (Swift), so they are relabelled CHANGED, UNVERIFIED, a verdict now defined in the legend, and are verified only by the v2.9.3 device checklist. AUD-32 gained the evidence it lacked: from a scratch directory seeded with every artifact, the v2.9.1 `clean` left six of them, the new rule leaves only the two .qsf snapshots (kept on purpose), and dropping sweep-logs-offdie from the rule is caught. AUD-09's red and mutation are stated explicitly. CORRECTION: the ledger commit (a3a4f6b) tallied FIXED 19; it is 17 (16 of the report's 32 plus AUD-02b), and the release text is corrected to "16 of the 32 are fixed" to match. Docs drift (CodeRabbit, real). docs/apu-2a03.md said every CPU read sets the internal data bus; the $4015 read returns before the latch is assigned (bus.rs, the `addr == 0x4015` branch), which is exactly what keeps bit 5 on the older value. Both libretro docs stated the serialize headroom unconditionally; a Vs. DualSystem cabinet gets none, because it never attaches a device. Mobile test (CodeRabbit, trivial, taken): the HD-frame containment test now also asserts that compositing resumes after the power cycle that thaws it. CodeQL "hard-coded cryptographic value used as a salt" x5 (false positive): a test-only pattern generator named its XOR parameter `salt`. Renamed `seed`; no cryptography is involved anywhere near it. Not a defect (CodeRabbit, "Major"): that a sender with input_delay 1100 could leave a frame unconfirmed past MAX_SESSION_FRAME_LOOKAHEAD. No frontend or the mobile bridge sets input_delay -- every session uses SessionConfig's default of 2 -- and a delay beyond INPUT_RESEND_WINDOW (64) already defeats the resend window with or without this bound.

…lared crates/rustynes-core/src/bus.rs said, in a doc comment at the site, that `oam_dma_read_reg_active` is a "Direct port of the TriCNES Fetch addressBus-window block", and its unified-DMA state fields (`dmc_halt`, `uni_oam_active` / `_halt` / `_aligned` / `_addr`) name the TriCNES DMA flags they model. The derivation was never hidden -- NOTICE already records TriCNES's "per-cycle DMA-dispatch models" as ported into rustynes-core, and section 5 of docs/originality-and-provenance.md attributes the crate -- but the file carried no `// Provenance:` header, so it had no section 1 row, and the check this project relies on before any HDL work (`grep -rln "^// Provenance:" crates`) did not list it. For the MiSTer sibling that matters: its DMA is exactly the logic this region models, and a region that is derived is a black box for RTL purposes whether or not the file is ours. Found during the v2.9.2 audit triage and raised with the maintainer, who directed the header (2026-09-28). Nothing is reworded or removed: the site comments stay exactly as written, and the header states only what they already claim -- one block a direct port, the DMA state modelled on TriCNES's flags -- neither more (the rest of the bus is RustyNES's own) nor less. - bus.rs: SPDX line and a `// Provenance:` header in the form the other 26 derived files use. - originality-and-provenance.md section 1: a TriCNES / MIT row for bus.rs. - NOTICE: unchanged; its TriCNES entry already names the DMA models and rustynes-core. For the record on the sibling: the v2.9.2 AUD-24 fix (the /NMI edge detector during a DMA) was written from nesdev's CPU_interrupts page and pinned by a per-cycle golden diff (dmanmi074); this region of bus.rs was not read for it. Verified: provenance_record_audit 2 passed (header <-> section 1 row, both directions); cargo fmt --check clean.

…ate pair The third release of the v2.9.x line (ADR 0041). The workspace moves 2.9.1 -> 2.9.2 (root and the excluded rustynes-cosim, both Cargo.locks, the libretro .info display_version). scripts/release-automation/bump_release.py moved every anchor; ROADMAP.md's status line and to-dos/ROADMAP.md's release-line chain were extended by hand, because the tool refuses (correctly) to mechanically bump prose that describes a release. What the release is, for the record the tag carries: - A 32-finding, AI-written audit of both repositories, triaged row by row in docs/audits/v2.9.2-full-audit-disposition.md: 16 FIXED red-first with a caught mutation, AUD-02b (nine more boards) FIXED the same way, 2 CHANGED, UNVERIFIED (Swift, device checklist at v2.9.3), and the rest refuted, declined or deferred with evidence. The commits carrying each fix are named in the ledger. - Emulation output changes in exactly one place, AUD-03 (an unmapped $4020-$FFFF read updates the internal data bus). Save-state sections grow on the fifteen fixed mapper ids (twelve board families) and stay loadable across versions. - Opposing-direction cancel (AUD-08/09/10) is ON BY DEFAULT by the maintainer's decision (2026-09-28), an explicit exception to the off-by-default rule; the ledger rows, CHANGELOG, release notes and AGENTS.md now say "decided" where they said "pending". - AGENTS.md's firewall sentence lists rustynes-core/src/bus.rs among the files whose derived regions bite HDL work (header added in 191f928). Gates, measured on this tree (release notes and VERSION-PLAN carry the same numbers): cargo test --workspace --features test-roms --release: 2,867 passed, 0 failed, 20 ignored (v2.9.1: 2,812) AccuracyCoin (RAM) total=144 pass=133 pass_with_code=11 fail=0; nestest nestest_pc_c000_matches_golden_log ok fmt; clippy workspace + scripting + scripting,hd-pack + retroachievements + full + both wasm32; RUSTDOCFLAGS=-D warnings cargo doc; thumbv7em no_std; markdownlint --all-files; release_anchor / release_state_prose / release_notes_render / contribution_checklist / provenance_record audits Android :app:testFossDebugUnitTest BUILD SUCCESSFUL MiSTer (sibling feat/v2.9.2-audit-and-rc): ladder 173/0/1 on-die and 174/0/1 off-die, one frozen-worktree run each, nothing skipped; eight-seed sweeps of both builds at build date 260928, all sixteen closing, pin stays 2 (on-die +0.510/+0.108 ns, off-die +0.390/+0.081, SDRAM read +0.447/+1.184); two clean compiles of each byte-identical (on-die c17b0f37d5c49b150c023734b583f468, off-die 75ae3a99e840e29675ded9898dae127d). Not verified here: every Swift change (AUD-10, AUD-14 and the review-round fixes to both) is uncompiled; the Android NTSC index-buffer reuse (AUD-12) has no host test. No hardware has run any bitstream; v2.9.2's pair is what the SuperStation One session runs.

- Around line 14-15: Add a definition for the CHANGED, UNVERIFIED verdict to the
audit workflow’s verdict table, matching the meaning used in this ledger: code
has changed, but its named check has not run, so it is not yet FIXED.
- Line 28: Update the AUD-09 disposition row so it has one clear account of
cross-source behavior: remove the statement that opposing touch and hardware-pad
directions are not cleaned, or explicitly mark it as describing the earlier
implementation; make clear the final behavior cleans the combined touch,
gamepad, and keyboard mask in applyPort and p1Mask.
Review comments at @docs/originality-and-provenance.md:
- Line 62: Update the derivation table’s introduction and license explanation to
reflect that its upstream sources include both GPL-licensed and permissively
licensed code, rather than stating that all sources are GPL-licensed. Retain the
TriCNES attribution and its MIT license entry.

…on 1 intro) CodeRabbit's three findings on the release commit, all real, all docs. - docs/audits/README.md's verdict table did not define CHANGED, UNVERIFIED, the verdict the v2.9.2 ledger introduced for code that no gate on this machine can run (the Swift halves of AUD-10 and AUD-14). It does now, with the rule that such a row is not FIXED until its named device-checklist check has run. DEFERRED and DECLINED, which the v2.9.2 ledger also uses, were missing from the table too; they are added with the meaning the ledger legend already gave them. - The AUD-09 ledger row still said a touch direction plus the opposite on a hardware pad "is not cleaned" after a later sentence in the same row said applyPort and p1Mask now clean the combined mask. The first sentence now describes the code as first written and points at the review fix. - docs/originality-and-provenance.md section 1 said every upstream in the derivation table is GPL. That was already false before this release -- the table carries emu2413 (MIT), blip_buf (LGPL-2.1-or-later) and ares (BSD-2-Clause / Apache-2.0) -- and the bus.rs TriCNES (MIT) row made it more visible. The heading and introduction now say what the table holds and why every licence in it is compatible with GPL-3.0-or-later. No row changes. Nothing links the old heading's anchor (git grep), and provenance_record_audit, which finds the section by its "## 1. " prefix, still passes 2/2.

Copilot on #563, round 2. AUD-06's max_accepted_frame() adds input delay, rollback window and MAX_SESSION_FRAME_LOOKAHEAD to current_frame with saturating arithmetic, so a session close enough to the end of the frame space accepts frame == u32::MAX -- and ensure_frame sizes its six tables as `frame as usize + 1`, which overflows a 32-bit usize (wasm32, armv7, i686) at exactly that value, and asks for a 4G-entry resize on 64-bit. The guard was sound everywhere except its own endpoint. Unreachable in play: current_frame would have to pass u32::MAX - 1036, which is over two years of continuous play at 60 fps. The clamp costs one comparison, and the guard is the one thing that must hold at its edge, so it is taken rather than argued. max_accepted_frame() now returns u32::MAX - 1 when the saturated window reaches u32::MAX. Red: lookahead_window_never_reaches_u32_max (current_frame = u32::MAX - 3) returned 4294967295, expected 4294967294. Green after. Reverting the clamp is the red run itself. rustynes-netplay: lib 88 passed, determinism 16, loopback suites pass; clippy clean. Also Copilot, docs: docs/mappers.md said the AUD-02b boards were "outside the VRC family" while listing mapper 75 (VRC1) and 151 (a VRC1 wrapper). It now says they are beyond the VRC2/4/6/7 set AUD-02 fixed, VRC1 among them.

CI rustdoc (-D warnings) failed on 60b6c7c: the new doc comment on the public max_accepted_frame() linked [`ensure_frame`](Self::ensure_frame), a private method, which rustdoc rejects as a private intra-doc link. It is now a plain code span. My miss: that change ran clippy and the netplay tests but not the doc gate; RUSTDOCFLAGS="-D warnings" cargo doc --workspace --no-deps is clean now.

Antigravity on #563, round 2. Relay::leave_room (added for AUD-13) found the departing client's slot with `position(..).unwrap_or(0)`. The room map and the slot list are kept in step by join and leave, so a miss is a broken invariant -- but on that path every remaining peer was told `PeerLeft { slot: 0 }`, i.e. that the HOST had left, and would drop it. It now announces nothing when the client holds no slot, and still removes the client from the map. Red: leaving_a_room_that_does_not_list_the_client_announces_nothing maps client 3 to a room whose slots are [1, 2], disconnects it, and requires no actions and the room unchanged. On the old code it failed on the first assertion (a PeerLeft to each real player). Reverting the fix is that red run. Unreachable through the public API today; the guard is for the invariant. Declined from the same round, with reasons on the PR: - fds.rs `data[off..off + 4].try_into().unwrap()`: the exact-length check just above counts the trailing fields, so the slice is in bounds, and try_into on a 4-byte slice to [u8; 4] cannot fail. - compose_dual's clear() before resize(): that branch runs only when the buffer's length changes (first cabinet frame, or after an unload), not per frame; the per-frame zero-fill AUD-19 removed does not come back. rustynes-netplay lib 89 passed; clippy clean.

Replies to the Antigravity round-2 review:
|
The installed copy was an old one: scripts/agy-review.sh at 639 lines, against the template's 1,130. It lacked the template's diff-size timeout scaling, the permission-API write check for `/agy-review`, and today's two fixes (antigravity-pr-review 1f688b8): - `exec 9>&- 2>/dev/null` after the retry loop silenced every later log line for the rest of the script, so a posted review, an updated one and every failure looked identical in CI: the job logged "running agy ... [attempt 1/3]", then nothing, and went green. That is why agy looked broken on this PR while it was in fact editing its one comment in place each round. - agy exits 0 on its own --print-timeout, with partial output. That capture was posted as the review. It is now discarded and retried, and if every attempt times out the check fails and names AGY_PRINT_TIMEOUT. Installed with install-into-repo.sh, which kept .github/agy-review.md (the style guide), .github/actionlint.yaml and the .gitignore entry unchanged. One deliberate departure from the template: its first-install BOOTSTRAP steps (a write-access check, a PR-head checkout, and a copy into scripts/) are removed from the workflow, with a comment saying why. They fire only when the default branch has no reviewer, which is never true here, and their PR-head checkout in a privileged context trips CodeQL's actions/untrusted-checkout (high) on every scan -- the reason an earlier install in this workspace had to be reverted before merge. Verified: bash scripts/agy-review-selftest.sh -> "all checks passed" (including the new timeout and exec-redirect checks); the workflow parses as YAML and passes actionlint. The remaining shellcheck notes (SC1007 on the deliberate `var= var=` temp-file pre-declarations, SC2016) are the template's own and no gate in this repository runs shellcheck on these scripts.

Release commit
0f97ea0b(version 2.9.2, notes in.github/release-notes/v2.9.2.md). Round-1 review fixes in364b67c9; thebus.rsprovenance header in191f928f.The audit
A 32-finding, AI-written audit of both repositories, added by the maintainer (
docs/audits/v2.9.2-full-audit-report.md, kept as supplied). Every finding has a verdict, its evidence and its commit indocs/audits/v2.9.2-full-audit-disposition.md.
