chore(release): cut v2.4.1 "Fabric", carrying the never-tagged v2.4.0 - #430
Merged
Conversation
Promotes the accumulated CHANGELOG entries into a dated section, bumps the workspace version, and moves all 15 release anchors. Nothing else changes: no source file outside the two manifests is touched, so the shipped emulation core is the one that merged in #429. The release carries two versions, and that is not a naming convenience. v2.4.0 "Concordance" merged to main in #428 and was never tagged, so its entries were still sitting under [Unreleased] alongside v2.4.1's. Splitting them now would mean tagging v2.4.0 at a commit that main has already moved past, and publishing two releases minutes apart whose binaries are identical except for a version string. Instead the section states plainly that it carries both, and every entry belonging to the earlier one is marked (v2.4.0 item) so the attribution survives. Two entries belong to neither -- the release-anchor audit and the deferred-backlog sweep landed in #427, between the two -- and the preamble says so rather than letting "unmarked" silently mean v2.4.1. The version bump is deliberately part of this commit rather than an earlier one. Cargo.toml's own comment records why: release-auto.yml reads "workspace version has no matching tag" as "this is ready to release", so a bump that arrives early reaches main while the release does not exist and the workflow then fails closed on every push for want of release notes. Bumping here, with the CHANGELOG section and the release-notes override in the same change, is the only ordering that does not leave main red for a development window. Three mechanical consequences, each verified rather than assumed: - rustynes_libretro.info's display_version moves to v2.4.1, because libretro_info_audit.rs pins the LOCAL file against the workspace manifest. The cadence rule that lets display_version lag through a patch run applies to the UPSTREAM copy in libretro-super, which nothing here touches; the next upstream sync is still v2.5.0. - crates/rustynes-cosim/Cargo.toml carries its own version literal, because an excluded package cannot use `field.workspace = true`. cosim_manifest_audit.rs is what makes that duplication safe, and it is what would have caught this line being missed. - The CHANGELOG header is load-bearing, not decoration. release-auto.yml parses it for both the release-body fallback and the title codename, so the ` - <date> - "<Codename>" (<theme>)` shape is asserted by release_anchor_audit.rs rather than left to care. .github/release-notes/v2.4.1.md is a maintainer-authored override, so the published body is the narrative rather than the changelog. It discloses something the previous release's notes got wrong: v2.3.9's published body describes release_anchor_audit.rs, and `git cat-file -e v2.3.9:crates/rustynes-test-harness/tests/release_anchor_audit.rs` fails -- that work landed in #427, after the tag was cut. The audit exists because eight documents had reached six different answers about the current version; a release note describing work its own tag does not contain is the same failure one level up, so it is recorded here rather than quietly corrected. Anchors moved (15 across 10 documents, all named by the audit when it fails): README.md badge + Current Release, docs/STATUS.md, AGENTS.md x3 (the "What this is" block, the operating-notes bullet, and the never-claim-a-later-version guard), VERSION-PLAN.md header + its (current) table row, to-dos/ROADMAP.md, SUPPORT.md, SECURITY.md, ROADMAP.md x2, OVERVIEW.md x2, ARCHITECTURE.md. The VERSION-PLAN table gains a row for each of v2.4.0 and v2.4.1; the audit asserts exactly one row is marked (current), so a forgotten row fails loudly. Gates run on this tree, not inherited from the merge: fmt (workspace + the excluded crate), clippy --workspace --all-targets, the excluded crate's clippy, the four frontend feature combinations (scripting; scripting,hd-pack; retroachievements; full), BOTH wasm32 invocations, the no_std thumbv7em build, rustdoc with warnings as errors, cargo deny (advisories/bans/licenses/sources ok), actionlint, and markdownlint over every changed document. Tests: 126 workspace suites / 2222 passed / 0 failed, plus the excluded crate's 3 suites / 14 passed, which --workspace cannot reach. Accuracy re-run rather than reasoned about, since rustynes-core changed in both halves of what this tags: AccuracyCoin (RAM): pass rate = 100.00% over 141 assigned tests nestest_pc_c000_matches_golden_log ... ok The framebuffer decoder reports 120 and stays known-buggy; the RAM decoder is the authoritative one.

Keep the local libretro metadata on the patch-release sync policy.
AGENTS.md states that patch releases do not trigger upstream sync and that display_version may lag through v2.4.1–v2.4.9. The next scheduled sync is v2.5.0. Changing this value to v2.4.1 creates an undocumented exception.
As per coding guidelines, follow the repository-specific instructions documented in AGENTS.md; its libretro policy says patch releases do not trigger an upstream sync and the .info version may lag until v2.5.0.

Align OVERVIEW.md with the active scheduler.
OVERVIEW.md Lines 35 and 71 still describe PPU-dot lockstep with the PPU as master clock. The active CPU path uses start_cycle/end_cycle, per-cycle bus accesses, and run_ppu_to catch-up. Update both statements to describe the one-clock, every-cycle-bus-access model.

Line 5 names v2.4.1 as the current release, but Line 13 still marks 2.3.x as “The current line” and the table has no 2.4.x row. This can direct security reports to the wrong release line. Add 2.4.x and recategorize 2.3.x to match the stated patch policy.

| **Current release: v2.3.9 "Crucible"** — what the gates actually cover. A crucible tests to destruction rather than inspects, and this release does that to the project's own checks. **The docs-only CI skip had never worked**: `predicate-quantifier` defaults to `some`, so the `code` filter's leading `'**'` matched everything and all seven `!` exclusions under it were dead from the day they were written — fixed with **two** filter steps, because the quantifier is step-level and `accuracy` is a list of *alternatives* that becomes unsatisfiable under `every`, so the one-line fix would have silently disabled the accuracy battery while repairing a different gate. **`test-roms` now runs at review time**, path-filtered over the chip crates, the core, `rustynes-gamedb`, the harness and `tests/` (11 of the last 40 merged PRs, so ~72% still pay nothing). **A freeze from one cartridge kept writing into the next** — an active per-frame write into the wrong game — closed by a ROM-transition sweep across every panel under one rule: derived output discarded, user-authored input kept, and only input that actively *writes* neutralised. **The config file is written atomically and durably** (seven properties, five from review rather than the first draft). Plus 257 lines of dead code removed, 25 of 29 `#[allow(dead_code)]` attributes found to suppress nothing, `undocumented_unsafe_blocks` made a gate, and two `cargo deny` ignores retired on their own stated condition. `rustynes-apu` and `rustynes-core` both change, so **AccuracyCoin 141/141 and nestest 0-diff are verified, not asserted**. Built on **v2.3.8 "Parallax"** — which pixels differ, not just which frame: `Probe` could say two configurations of the same ROM diverge and *at which frame* and nothing about where or why, because a trial reduces each frame to one `u64`. The **Divergence Lens** keeps the full output instead of its hash and reports the *shape* of the difference (population count, first pixel in raster order, inclusive bounding box), localises on the **index** framebuffer so a palette difference cannot masquerade as a rendering one, hands the located pixel to Pixel Provenance so the answer is a cause rather than a coordinate, and answers `Inconclusive` rather than letting "I stopped looking" wear the shape of "they agree". Built on **v2.3.7 "Overtone"** — the audio-provenance release: a per-register write attribution (*what wrote this, and from which instruction*) plus a per-CPU-cycle mix trace, and the discovery that Pixel Provenance had shipped non-functional for four releases because run-ahead's rollback cleared its store before any UI could read it — in three more places than the v2.3.6 fix had enumerated. Built on **v2.3.6 "Sounding"** — measuring, and what a measurement may claim. Two shipped features are found never to have worked: **Pixel Provenance** returned an empty report for every user on the default `run_ahead = 1` (its rollback is the last thing before the frontend takes the lock, so the panel always looked after the wipe) and "click any pixel" was never implemented — two comments and four doc claims asserted the opposite of their own code, which is why four releases passed unchecked; and **Duck Hunt could never score**, its Zapper probe exactly inverting the "see nothing, then a bright spot" protocol. Two new tools built to **decline rather than guess**: the **Latency Oracle** (measures the game's own input lag; recommends a run-ahead depth and never applies one) and the **RAM Atlas** (classifies all 2 KiB of work RAM, then *verifies* a candidate by perturbing it — `Untested` is a third state distinct from `Inert`, and liveness names its lens). **APU Workstream D is closed** on three measured rejections plus the fat-LTO mechanism explaining them. Tools and Debug are regrouped by task. Core gains one `const fn` getter, so AccuracyCoin 141/141 is verified, not asserted. Built on **v2.3.5 "Manifest"** — the declaration release: what the core says about itself. A user reported RetroArch still showing the pre-relicense MIT/Apache-2.0 terms, and it was: RetroArch reads `dist/info/` from **libretro/libretro-super**, a SEPARATE copy nothing synced, so the v2.2.9 GPL relicense never reached the file users see. Corrected to `GPLv3+` with a standing `libretro_info_audit.rs` that makes the upstream sync a **copy** rather than a re-derivation, and a licence change is now a mandatory upstream-sync trigger. Auditing the wrapper then found **five further defects, every one with correct emulation behind it** — PAL ran 20.2% fast, Reset did nothing ever, unload leaked Game Genie indices, the aspect ratio assumed square pixels, and the Zapper was unreachable — plus a **use-after-free** in the controller tables caught in review. The crate went from zero tests to eight. The APU also gained its first throughput bench and a default-configuration mix specialization (−3.3% to −4.2% on `nes_run_frame_nestest`), so **AccuracyCoin 141/141 was VERIFIED, not asserted**. Built on **v2.3.4 "Ledger"** — the coverage release: three boards (mapper 176 submapper 2 WAIXING-FS005, 154 NAMCOT-3453, 243 Sachen SA-020A, breadth **172 → 174 families**), the coverage harness moved onto the frontend's real load path, and the defect that exposed — the per-game database reading a `0` Mapper column as "force NROM" and overwriting correct headers, leaving **every Sachen cartridge** unloadable since **v1.2.0**. **This release touches the emulation core**, so AccuracyCoin exactly 141/141 is **verified, not asserted by construction**. Its Workstream C (the APU at 18.7% of frame time) was carried to v2.3.5 and delivered there. Built on **v2.3.3 "Cadence"** — the display-pacing release: the run-ahead throttle oscillation traced to a stale median (a gate counting 120 frames of a 600-sample ring), a predictive engage arm that converges a `run_ahead = 3` host in 2.8 s instead of 12.1 s, and the `wp_presentation` measurement apparatus that made the diagnosis possible. **No emulation-core changes** (AccuracyCoin exactly 141/141). Built on **v2.3.2 "Lucid"** (pixel provenance + deterministic replay attestation), **v2.3.1 "Plumb Line"** (ten measured rejections), and **v2.3.0 "Datum II"**, the capstone that **closed** the v2.2.6 → v2.3.0 line (true multi-viewport OS-window detach, the emulator-lock frame-pacing fix, a −5.1% byte-identical PPU optimization, and both forum-reported accuracy items verified already-correct) — all on the **v2.0.0 "Timebase"** MAJOR base (the one-clock / every-cycle-bus-access scheduler rewrite). **v1.0.0** was the first stable, production cut. As of **v2.2.9**, RustyNES is **GPL-3.0-or-later** — a derivative work of GPL-licensed emulators (ADR 0036); a licensing correction, **not** a SemVer break (no public-API or save-state change). `docs/STATUS.md` is the authoritative current-state record; `CHANGELOG.md` carries the full per-release history. | ||
| **Current release: v2.4.1 "Fabric"** — RustyNES as the oracle a new implementation is verified against. It opens the **v2.4.1 → v2.5.0 "Fabric"** line: a new NES core in SystemVerilog, written from public hardware documentation in a sibling repository, with this emulator as its verification oracle. RustyNES is not being ported to FPGA and cannot be; `crates/rustynes-cosim` is the boundary, and the firewall extends to HDL (ADR 0037). **v2.5.0 is scoped to "the 6502 rung closes"**, not a finished core. Excluding the crate from the workspace is the load-bearing detail — cargo unifies features, and `irq-timing-trace` selects a *different* per-dot loop in `Bus::tick_one_cpu_cycle`, so the accuracy battery had been validating a scheduler no user runs. It also carries **v2.4.0 "Concordance"**, which merged to `main` and was never tagged: atomic durable writes on every path that persists user data, `Nes::timeline_generation()`, and the 15-anchor release audit. AccuracyCoin **141/141** and nestest 0-diff verified, not asserted. Previously, **v2.3.9 "Crucible"** — what the gates actually cover.

Cuts v2.4.1 "Fabric". No source file outside the two manifests changes, so the shipped emulation core is the one that merged in #429.
It carries two versions
v2.4.0 "Concordance" merged to
mainin #428 and was never tagged, so its CHANGELOG entries were still sitting under[Unreleased]alongside v2.4.1's. Splitting them now would mean tagging v2.4.0 at a commitmainhas already moved past, and publishing two releases minutes apart whose binaries differ only in a version string. The section states plainly that it carries both, and every v2.4.0 entry is marked (v2.4.0 item). Two entries belong to neither — the release-anchor audit and the deferred-backlog sweep landed in #427, between the two — and the preamble says so rather than letting "unmarked" quietly mean v2.4.1.What the published notes disclose
