Summary

v3.4.1 "Beacon", a patch release on v3.4.0 (plan: to-dos/plans/v3.4.1-plan.md). No emulation-core change: epoch 5, protocol 9.

  • Hosted services live. The Worker is deployed on the maintainer's Cloudflare account (https://rustynes-hosted.parobek.workers.dev), and RUSTYNES_HOSTED_BASE is set in web.yml, release.yml, android.yml and ios.yml. ci.yml is deliberately left unset so a_stock_build_has_no_hosted_base still asserts the default.
  • RA proxy deployed OFF (RA_ENABLED "false"). Web RA is held until RetroAchievements answers the integration request (D31). vitest.config.ts binds it to "true" so the proxy stays under test; flipping that binding makes 26/111 tests fail.
  • Browser RetroAchievements packaging fixed (three faults). It is not enabled on Pages.
    • The empty data-cargo-features attribute made trunk ignore --features and --no-default-features. The canvas build was 12.6 MB and is now 1.3 MB.
    • The glue's import of rcheevos resolved inside snippets/.
    • The rcheevos module had no ES export.
  • MiSTer release assets version-named. The docs follow the rename of all 49 past assets and the rewrite of 44 release bodies.
  • The version bump, the CHANGELOG, VERSION-PLAN and the plan doc.

Live gates (2026-10-18)

  • /healthz returns ok; a GET returns 405.
  • POST /turn-credentials returns 200 with ttl 10800 and an expiry 3 h ahead. The 7th POST from one address returns 429.
  • RA requests return 503 (the proxy is off).
  • hosted_lobby_live against the live /signal: 1 passed.
  • Kill switch: 503 turn-disabled while off, then restored.
  • A headless Chromium relay-only ICE gather gathered 8 relay udp candidates.

Still pending:

  • the credential-expiry gather (after 02:44Z);
  • two browsers through the lobby, a two-NAT relayed session, and the RA unlock (maintainer).

Local gates (at 028585b)

  • cargo fmt --check and cargo clippy --workspace --all-targets -D warnings: clean.
  • cargo test --workspace: 3,180 passed, 0 failed, 9 ignored.
  • --features test-roms: 3,547 passed, 0 failed, 13 ignored.
  • All 12 harness audit targets: pass.
  • Worker: vitest 111/111 and tsc --noEmit clean.

Still to land before merge

.github/release-notes/v3.4.1.md, with the MiSTer bitstream figures. Both builds are compiling now at the pinned seed 2.

At the maintainer's direction (2026-10-18), this release skips the seed sweep and does not wait for the ladders; the notes will say so.

Note

Medium Risk
Compile-time embedding of the production hosted URL across release pipelines and PGO promotion logic affects what every shipped binary uses for netplay; dependency and toolchain bumps add ordinary integration risk but no emulation-core changes are claimed.

Overview
v3.4.1 "Beacon" ships the hosted netplay lobby in release builds by setting compile-time RUSTYNES_HOSTED_BASE on Android, iOS, web, and desktop release workflows (while ci.yml leaves it unset so default-behaviour tests still pass). release.yml forwards the same URL into pgo.yml, which now copies the optimized rustynes binary before the test-oracle rebuild, verifies the hosted URL is embedded in the promoted artifact, and uploads from pgo-out/ so Linux releases keep full features and the hosted base.

The workspace moves to 3.4.1 with a full CHANGELOG and new .github/release-notes/v3.4.1.md; v3.4.0 notes are updated for version-named MiSTer .rbf assets. Rust 1.99.1 and a Cargo.lock refresh align CI, libretro buildbot, and pins (dtolnay/rust-toolchain, taiki-e/install-action, Python 3.15 for MkDocs, ruff).

Android bumps app version, treats empty/placeholder signaling as “use hosted”, and gates online netplay on npHostedAvailable(). PRIVACY.md reflects TURN relay off and revised credential retention wording.

Summary by CodeRabbit

  • New Features
    • Hosted netplay lobby is available in shipped builds. Android and iOS support room-code play without custom relay settings; custom service settings can override hosted defaults.
    • MiSTer release assets use version-based filenames for off-die and Lite builds.
  • Bug Fixes
    • Fixed browser RetroAchievements packaging, MiSTer save handling during cartridge changes, and issues found in v3.4.0 builds.
    • Corrected warnings in MiSTer builds.
  • Service Status
    • TURN relay credentials are not currently issued; connections use direct or STUN paths, so some peers behind strict NAT may not connect.
    • RetroAchievements remains unavailable on the public web demo.

On 2026-10-18 the maintainer chose the version-named style for every
release's bitstream assets, after first having the version-named
duplicates deleted the same day. All 49 datecoded .rbf assets on both
repositories were renamed in place (RustyNES_MiSTer-<tag>.rbf, and
RustyNES_MiSTer-v3.4.0-lite.rbf for v3.4.0's on-die build); the bytes and
the GitHub-recorded SHA-256 digests are unchanged, and 44 release bodies
were rewritten to name the attached file by its version. The sibling's
release-rbf.sh now uploads that form (sibling 4e71c79), while its
releases/ keeps the datecoded names Distribution_MiSTer parses.

Three docs here still described the brief datecoded-only state:
docs/mister.md, to-dos/mister/TASKS.md and the v3.x hardware-verification
plan. They now say: datecoded in the sibling's releases/, version-named
on the releases. .github/release-notes/v3.4.0.md is synced to the live
v3.4.0 body, which differs from the committed file in exactly the three
asset names (checked by diff, ignoring trailing blank lines GitHub
appended).

Verified: pre-commit markdownlint passes on all four files.

Building the web frontend with `--features browser-cheevos`, as the
v3.4.1 hosted plan needs, found three packaging defects. Each one alone
stopped the browser RetroAchievements glue from ever reaching rcheevos;
none was visible to a gate, because no CI job builds that feature and
the Pages build uses the default set.

1. index.html carried `data-cargo-features=""`. Trunk lets that
   attribute override its command line, and an EMPTY value silently
   discarded `trunk build --features ...` and `--no-default-features`.
   Measured: the documented lightweight build (`--no-default-features
   --features wasm-canvas`) produced the default 12.6 MB winit build;
   with the attribute gone it produces 1,336,570 bytes, and the
   browser-cheevos build now emits the RA glue snippet. The Pages build
   (`trunk build --release`, default features) is unaffected, since an
   empty list on top of the defaults was the defaults. A comment at the
   site says why the attribute must stay absent.

2. ra_glue.js imported "./rcheevos.js". `#[wasm_bindgen(module = ...)]`
   makes trunk emit the glue as `snippets/<crate>-<hash>/web/cheevos/
   ra_glue.js`, and nothing copies the Emscripten module there, so the
   relative import resolved inside snippets/ and 404ed. The module is
   now resolved against the PAGE: `<meta name="rustynes-rcheevos-base">`
   when present, else `cheevos/` beside the page. `locateFile` points the
   loader at rcheevos.wasm under the same base, so both paths are stated
   in one place rather than relying on Emscripten resolving the .wasm
   against its own script.

3. build_rcheevos_wasm.sh emitted a MODULARIZE UMD module, which has no
   default export, so the glue's `const { default: ... } = await
   import(...)` got undefined. `-sEXPORT_ES6=1` makes it an ES module.

Verified in headless Chromium against a Pages-layout copy of dist/
(served on 127.0.0.1:18765): `ra_rcheevos_version()` returned 12.5 and
every request was 200. Control: the old glue against the same layout
404s on snippets/.../rcheevos.js. The README's wiring steps and the two
script-tag passages in docs/cheevos-browser.md are corrected to match;
markdownlint passes on both.

Not done, deliberately: browser-cheevos is NOT enabled on Pages and no
RA proxy meta tag is added. The maintainer is holding web RA until the
RetroAchievements integration request is sent; this change only makes
the feature work when it is turned on.

v3.4.0 shipped services/hosted/ as code with no workflow setting
RUSTYNES_HOSTED_BASE, because the maintainer was away and the deploy
moved to v3.4.1. The account is now provisioned (budget alerts, the TURN
key `rustynes-hosted`, its two secrets on the `rustynes-hosted` Worker),
so the shipped builds point at it:
https://rustynes-hosted.parobek.workers.dev (account subdomain
`parobek`).

Scope, as the maintainer chose it: the Pages build (web.yml), the
desktop release binaries (release.yml), the Android Play and sideload
bridge builds (android.yml, cargo-ndk) and the iOS TestFlight
xcframework (ios.yml). F-Droid is excluded; its recipe builds from source
under its own rules. Each workflow gets the variable in its top-level
env block, so every job in it compiles the same base and no step can
silently miss it.

Why env and not a flag: rustynes-netplay reads it with option_env!, so
it is a compile-time constant (BUILD_HOSTED_BASE). A build without it
keeps v3.4.0's behaviour, and a user's `hosted_base_url` config still
wins over the baked value. ci.yml is deliberately left alone:
hosted.rs's a_stock_build_has_no_hosted_base asserts the constant is
None, guarded on the variable being absent at test time, so setting it
there would turn that test into a no-op rather than fail it.

The Worker's ALLOWED_ORIGINS already lists https://doublegate.github.io
and index.html carries no CSP, so the Pages origin needs nothing more.
The live smoke gates (healthz, the lobby test, POST /turn-credentials,
the rate limit, the kill switch) run against the deploy, not here.

The v3.4.1 deploy puts the lobby and TURN credentials live and leaves
the RetroAchievements proxy switched off. The maintainer is holding web
RA until RetroAchievements answers the integration request (D31), and
the Pages build ships without browser-cheevos, so no client would use
the proxy; leaving it enabled would only let anyone forward RA calls
under the RustyNES/ User-Agent before RA has agreed to that. RA_ENABLED
is therefore "false" in wrangler.jsonc, with the reason at the site.
ra.ts refuses every /ra/ request unless the value is exactly "true", so
the off state is the kill switch path, already tested. Turning it on is
a dashboard variable change, no code.

RA_USER_AGENT moves to RustyNES/3.4.1 (Web wasm32) rcheevos/12.5.0, the
release this config ships in. bump_release.py does not touch it, so it
is bumped by hand.

The Worker tests run against wrangler.jsonc's own vars, so turning the
proxy off there would have stopped the proxy being tested at all.
vitest.config.ts now binds RA_ENABLED "true" for the tests (the
kill-switch test still sets "false" itself). Mutation: with that
binding flipped to "false", 26 of 111 tests fail; with it "true", 111
pass. tsc --noEmit is clean.

Also: docs/agents/tooling-traps.md records the trunk trap behind the
earlier web fix (an empty data-cargo-features attribute silently
overrides --features and --no-default-features).

to-dos/plans/v3.4.1-plan.md records the patch release v3.4.0 left: the
hosted deploy (done 2026-10-18, live gates passed: healthz, the live
lobby test, credentials with ttl 10800 that relay in a browser, the
429 on the 7th request, the 405, the kill switch), the client wiring,
the browser RA packaging fix, the two save-engine defects and the two
refusal findings (sibling 419ee1b, 9e7ef9c), the version-named release
assets, and what stays open: the credential-expiry check after
2026-10-19T02:44Z, the two-browser and two-NAT sessions (maintainer),
the RA unlock (held for D31), the v3.4.1 bitstreams and the
release-rbf.sh run before the release PR merges.

It also records the agent's call that follows from holding web RA: the
Worker is deployed with RA_ENABLED false.

CHANGELOG [Unreleased] gains Added / Changed / Fixed entries for the
same. release_anchor_audit (14), release_state_prose_audit (16),
contribution_checklist_audit (4) and release_notes_render_audit (9)
pass; markdownlint passes on both files.

The CHANGELOG [Unreleased] entries become [3.4.1] - 2026-10-19 -
"Beacon" (the codename the maintainer chose), and
scripts/release-automation/bump_release.py moved every anchor from it:
the workspace and cosim manifests and both lockfiles, the libretro
.info display_version, Android versionName 3.4.1 / versionCode 30401,
iOS MARKETING_VERSION, and the current-release prose in AGENTS.md,
README, ROADMAP, SECURITY, SUPPORT, OVERVIEW, ARCHITECTURE, STATUS and
VERSION-PLAN, each demoting "Waypoint" rather than overwriting it.

The script first refused: to-dos/ROADMAP.md's release-line chain still
ended "v3.4.0, the current release". That chain now has a v3.4.1 clause
saying what the release did, and v3.4.0's clause lost the tail.
VERSION-PLAN's v3.4.1 row is marked shipped with what it shipped, and a
v3.4.1 history row sits above v3.4.0's.

The date is 2026-10-19 because the MiSTer bitstreams are compiled that
day: BUILD_DATE is the wall-clock date, and a compile on a different
day is a different design and a different file name.

Verified: every harness audit target (12) passes, among them
release_anchor_audit 14, release_state_prose_audit 16; markdownlint
passes. .github/release-notes/v3.4.1.md is written after the compiles,
when its figures exist.

📝 Walkthrough

RustyNES v3.4.1 configures hosted netplay in shipped builds and mobile clients, updates browser RetroAchievements packaging, and standardizes MiSTer GitHub bitstream names. The release also adds hosted TURN credential revocation, updates the PPU emphasis table module, and revises release records, toolchain pins, dependencies, and version references.

Changes: Release and Build Updates

Layer / File(s) Summary
Hosted netplay build and mobile configuration
.github/workflows/*.yml, .github/workflows/pgo.yml, android/app/src/main/java/com/doublegate/rustynes/*, android/app/src/main/res/values*/strings.xml, ios/RustyNES/*, crates/rustynes-mobile/src/lib.rs, crates/rustynes-test-harness/tests/release_anchor_audit.rs
Shipped workflows set RUSTYNES_HOSTED_BASE; PGO accepts and exports the value when provided and checks the preserved binary before promotion. Android and iOS use hosted availability when configuring room-code play and settings. Release checks verify hosted-base and version configuration.
TURN credential revocation
services/hosted/src/{budget,turn}.ts, services/hosted/test/turn.test.ts, services/hosted/{README.md,vitest.config.ts,wrangler.jsonc}, services/hosted/test/*
The Worker schedules credential revocation at expiry, retries eligible failures, and re-arms alarms for pending revocations. TURN is disabled in deployment configuration, while tests enable the binding and exercise the revocation path.
Browser RetroAchievements packaging
crates/rustynes-frontend/web/cheevos/*, crates/rustynes-frontend/web/index.html, scripts/cheevos/*, services/hosted/test/ra-glue.test.ts, docs/cheevos-browser.md, docs/agents/tooling-traps.md, CHANGELOG.md
The Emscripten build emits an ES module. The glue resolves the module and its assets from the page-configured base and shares in-flight loads. Trunk feature selection, setup instructions, and base-path tests are updated.
MiSTer asset naming
.github/release-notes/v3.4.0.md, .github/release-notes/v3.4.1.md, docs/mister.md, to-dos/mister/TASKS.md, to-dos/plans/v3.x-hardware-verification-plan.md
Release notes and records use versioned GitHub asset names for off-die and Lite bitstreams. The documentation distinguishes these names from date-coded names in the sibling repository.
Release version and toolchain updates
Cargo.toml, android/app/build.gradle.kts, ios/project.yml, rust-toolchain.toml, .github/actions/rust-setup/action.yml, .github/workflows/*, .gitlab-ci.yml, .pre-commit-config.yaml, services/hosted/package.json, scripts/release-automation/bump_release.py
Project and platform version references advance to v3.4.1. Rust toolchain and CI action pins, hosted package dependencies, and release-version automation checks are updated.
PPU emphasis table module
crates/rustynes-ppu/src/*
The PPU emphasis table is declared as a public constant in a Rust module, and the generator emits that declaration.
Release records and supporting updates
CHANGELOG.md, to-dos/plans/v3.4.1-plan.md, to-dos/ROADMAP.md, docs/SALVAGE_MANIFEST.md, README.md, ROADMAP.md, VERSION-PLAN.md, docs/*, AGENTS.md, OVERVIEW.md, SUPPORT.md
Release records describe hosted services, browser packaging, MiSTer assets, save-engine fixes, and build findings. Current-release references and release history are revised; the salvage manifest records the v340 sweep.

Merge Risk: 🔵 Low · up to 641a8

This release is mostly mergeable. Before merging, fix the TURN documentation that overstates revocation guarantees, replace the [GATES] placeholder in the release notes, and tidy a few minor edge cases in the Android signaling check and the hosted alarm re-arming.

Security architecture risk: 🔵 Low · up to 641a8

The hosted-play defaults and credential cleanup warrant review. One scheduling flaw can retain pseudonymous address records longer than promised under supported settings. Relay credential issuance is disabled in the checked-in configuration, limiting immediate exposure; deployed settings and effective credential revocation remain unverified.

Retained concerns

  • Low · security · inferred: The new revocation lifecycle can delay the existing privacy cleanup obligation. Once a sweep removes all admission records, a future revocation may become the only alarm. A later admission leaves that alarm unchanged rather than advancing it to an hourly sweep. For example, with TURN enabled and the supported 24-hour TTL, a credential minted at 23:00 can leave a 23:00 next-day revocation alarm after the midnight sweep; an admission at 00:01 can then retain its pseudonymous address record until that evening, exceeding the promised two hours. This coupling is introduced by the PR, although admission's null-only alarm check predates it. The checked-in disabled switch and three-hour TTL substantially limit current exposure.
Security review details

Security Blast Radius

  • inferred — The independently attackable scope is the shared deployment: anonymous callers can consume permitted issuance capacity, and credential holders can incur relay egress against the maintainer's account. Default admission limits are six credentials per address per hour and 500 per day globally, not byte quotas. The retained scheduling issue affects pseudonymous records in that deployment; the inspected path establishes no attacker-readable access to those records.

Security Findings and Attack Paths

  • inferred — The retained finding is a deletion-deadline failure, not demonstrated exfiltration or privilege escalation. An external admission can create a record behind a distant existing revocation alarm. Reaching the clearest extended-retention scenario requires enabled issuance and a longer supported TTL, which callers do not select. The PR introduces the distant-alarm interaction; the null-only admission check already existed.
  • observed — The repository reports that Cloudflare accepted expired credentials and credentials whose revoke requests returned 204. This challenges a hard lifetime guarantee but is not shown to be introduced by this PR: the base already issued credentials without Worker-driven revocation. The PR adds cleanup and disables new issuance while provider behavior remains unresolved.

Trust Boundaries and Controls

  • observed — The router rejects disallowed supplied Origins, permits native-style requests without Origin, and derives admission identity from Cloudflare's client-IP header. POST-only issuance, an explicit enable switch, service-key configuration, and global admission precede privileged minting. Origin checks therefore constrain browsers rather than authenticate arbitrary callers.
  • observed — The Android change intentionally expands hosted reachability rather than replacing custom signaling authority. Nonempty user signaling URLs remain authoritative, and the inspected downstream path preserves the existing room-code and ROM-identity admission checks. A custom signaling URL alone does not disable the independent hosted TURN fallback.

Resilience and Maintainability Implications

  • inferred — The new cleanup mechanism provides best-effort recovery, not proof of a fixed credential lifetime. Issuance precedes durable scheduling; retry re-keying uses separate delete and put operations; records retain no issuing key ID; and current-key 404 responses or persistent failure beyond 48 hours terminate ownership. The source establishes these transitions, but production storage atomicity, rotation procedures, and provider enforcement are insufficiently established to report each as an independently exploitable regression.

Hardening Proposals

  • proposed — Advance an existing alarm when a new admission creates an earlier sweep obligation, independently of credential deadlines. Validate the transition from an empty admission store with a future revocation through new admission and deletion, including the supported maximum TTL.
  • proposed — Before re-enabling relay issuance, validate effective provider-side revocation and deployed controls. Establish loss-avoiding cleanup handoffs, issuing-key continuity across rotation, explicit handling of unconfirmed terminal cleanup, and retention disclosures that include retry states.

Full details: Docs-As-Spec Sync

Explanation

PASS: The PR changes only crates/rustynes-ppu and the change is an internal table refactoring. It replaces the include! array expression with a private module constant; all 512 table entries are identical between base and head, and consumers still read EMPHASIS_DELTA through the same apply_documented_emphasis path. No chip behavior changes, so this check does not require a docs update.

Full details: No Unwrap/Expect/Panic On Untrusted Input

Explanation

PASS. The reviewed diff adds no .unwrap(), .expect(), or panic!() call in production code. The exact-token diff scan found no such added lines. Existing matches in crates/rustynes-mobile/src/lib.rs and crates/rustynes-ppu/src/emphasis.rs are unchanged or test-only; the new hosted-service and browser code uses typed fallbacks and caught URL parsing errors.

Full details: Safety Comment On New Unsafe Blocks

Explanation

No new unsafe { ... } block or unsafe fn appears in the pull-request diff. The only changed Rust files add safe code and documentation; added-line searches found no unsafe or SAFETY: tokens. Therefore the SAFETY-comment requirement is not triggered.

Antigravity review (Gemini via Ultra)

This PR cuts the v3.4.1 "Beacon" release, wiring the deployed Cloudflare hosted netplay base URL into release builds, adding Durable Object alarm-driven TURN credential revocation, fixing PGO Linux binary packaging and browser RetroAchievements ES6 module loading, converting emphasis_delta_table.rs into a standard module for CodeQL, and updating Rust and dependency versions.

Blocking issues

None found.

Suggestions

  • services/hosted/src/turn.ts & L156-L168: In sanitizeIceServers, a turn:/turns: server with an empty-string username: "" or credential: "" passes typeof === "string", and an upstream response containing only stun: URLs returns a non-empty servers array with usernames = [] in handleTurn. Require username.length > 0 && credential.length > 0 for turn:/turns: entries and require at least one revocable TURN server before returning 200 OK so /turn-credentials never consumes a caller's TURN quota without issuing a valid TURN credential.
  • services/hosted/src/budget.ts: In revokeDue(), a failed revocation writes revokeKey(after + delay, username) and then deletes key. Although REVOKE_RETRY_MS is positive and after >= attemptAt under monotonic clocks, if the wall clock ever steps backward such that after + delay === attemptAt, delete(key) will delete the newly written retry entry. Guard the delete with if (nextKey !== key) (or delete key before calling put).
  • android/app/src/main/java/com/doublegate/rustynes/Netplay.kt: RELAY_URL (^wss?://[^/\s?#:][^/\s?#]*\S*$) rejects bare ws:// and ws://:8080, but still accepts malformed authorities such as wss://example.com:notaport or unclosed IPv6 literals (ws://[::1). Parsing with java.net.URI (verifying scheme is ws/wss and !uri.host.isNullOrEmpty()) would align Android's validation with iOS's URL(string:) check in ios/RustyNES/NetplayModel.swift.

Nitpicks

  • ARCHITECTURE.md, OVERVIEW.md, and ROADMAP.md: The version headers were bumped to v3.4.1, but the adjacent Last Updated: lines still read 2026-10-07 / 2026-10-06.
  • .github/workflows/pgo.yml: The pgo job now passes RUSTYNES_HOSTED_BASE and preserves the Stage 2 binary before Stage 4's cargo pgo optimize test, whereas the manual bolt job below it still builds without RUSTYNES_HOSTED_BASE and runs cargo pgo bolt optimize before cargo pgo bolt test on the same target path.

This PR cuts the v3.4.1 ("Beacon") release, wiring the hosted lobby URL across desktop/mobile/web workflows, fixing PGO binary staging so the hosted base survives cargo pgo optimize test, adding TTL-based TURN credential revocation to the Cloudflare Worker, repairing browser RetroAchievements WASM loading, and bumping the workspace and toolchain to 3.4.1 / Rust 1.99.1.

Blocking issues

None found.

Suggestions

  • turn.ts / budget.ts — Unhandled DO error in scheduleRevoke drops an already-minted TURN credential without refunding quota: handleTurn calls await budget.scheduleRevoke(usernames, expiresAt * 1000) after the upstream Cloudflare Calls API has already minted the credential and after the admission quota was charged. If scheduleRevoke throws due to a transient Durable Object or storage failure, the worker returns an unhandled 500 to the client while both the admission charge and the unrevoked upstream credential remain live. Catching scheduleRevoke errors (logging the failure while still returning the minted iceServers payload, or refunding admission if failing closed) would avoid penalizing clients on transient storage errors.
  • Netplay.kt vs. NetplayModel.swift — Custom signaling URL validation can drift from rustynes-netplay: Android validates custom URLs with a regex (^wss?://[^/\s?#:][^/\s?#]*\S*$) that permits malformed authorities like ws://host:notaport or ws://a][b, whereas iOS uses Foundation.URL(string:) + url.host. Exposing a single UniFFI validation function in crates/rustynes-mobile/src/lib.rs backed by the exact URL parser used by rustynes-netplay would guarantee identical validation across Android, iOS, and the Rust transport layer.
  • pgo.yml — bolt job does not forward RUSTYNES_HOSTED_BASE: The pgo job now accepts inputs.hosted_base and exports RUSTYNES_HOSTED_BASE during the optimized rebuild, but workflow_dispatch and the opt-in bolt job (PGO instrument + train + optimized rebuild) were not updated to accept or pass hosted_base, so manual BOLT builds will still compile without the hosted lobby endpoint.
  • ra_glue.js and ra_glue.js — Eager RA_PROXY_BASE vs. lazy rcheevosBase() resolution: rcheevosBase() is evaluated lazily inside loadModule(), whereas RA_PROXY_BASE is evaluated once at ES module import time (export const RA_PROXY_BASE = resolveProxyBase()). If an embedding page sets globalThis.RUSTYNES_RA_PROXY_BASE or injects the <meta name="rustynes-ra-proxy-base"> tag after module import but before calling ra_init(), rcheevosBase() will pick up the update while serverCallTrampoline will still see an empty RA_PROXY_BASE and fail closed.

Nitpicks

  • v3.4.1-plan.md vs. v3.4.1.md: Items 10c and 10e in the plan still say Compiling 2026-10-18 (BUILD_DATE 261018) and Pending: after the oracle merges, while the release notes record the finished 2026-10-19 (BUILD_DATE 261019) bitstreams.
  • release_anchor_audit.rs: Asserting "name": "rustynes-hosted",\n "version": "{v}" with literal newline and indentation counts is coupled to exact JSON formatting in package.json and package-lock.json.

This PR cuts the v3.4.1 "Beacon" release (bumping the workspace to 3.4.1 and Rust to 1.99.1), points shipped desktop, web, and mobile builds at the deployed Cloudflare Worker while keeping TURN and RetroAchievements budgets gated off, adds Durable Object alarm-driven TURN credential revocation on TTL expiry, and fixes PGO binary promotion, browser RetroAchievements (rcheevos.wasm) ES6 packaging, mobile hosted-relay fallback, and the CodeQL include! failure in emphasis.rs.

Blocking issues

None found.

Suggestions

  • revokeDue in services/hosted/src/budget.ts — Sequential fetch timeouts can stall the single-threaded Durable Object for up to 250 seconds:
    revokeDue iterates over up to REVOKE_BATCH (50) expired keys and awaits revokeOne (REVOKE_TIMEOUT_MS = 5000 ms) sequentially inside alarm(). If the upstream Cloudflare TURN revocation endpoint hangs or times out during an outage, a full batch will spend up to 50 * 5s = 250s inside alarm(), queuing or timing out live /turn/credentials and /ra/* admission requests on the global Durable Object and risking Worker alarm wall-clock eviction before reaching nextRevocation. Cap the total wall-clock time spent per alarm() turn (for example, breaking out of the loop after 10–15 seconds so nextRevocation(end) re-arms for the remaining keys) or run a small bounded batch concurrently.

  • RELAY_URL in android/app/src/main/java/com/doublegate/rustynes/Netplay.kt — Regex validation accepts malformed authority/port strings that iOS rejects:
    signalingConfigured in ios/RustyNES/NetplayModel.swift parses the string with URL(string:) and checks for a non-empty url.host, whereas Android's onlineNetplayConfigured matches against ^wss?://[^/\s?#:][^/\s?#]*\S*$. That regex rejects a leading colon (ws://:8080) but still passes malformed authority strings such as wss://example.com:notaport or wss://example.com::443, leaving the error to surface only at socket connect time. Parsing with java.net.URI and checking for a ws/wss scheme and non-empty host (or valid host/port authority) would keep Android and iOS validation consistent.

  • .github/workflows/pgo.yml — bolt job does not forward inputs.hosted_base:
    The pgo job now passes RUSTYNES_HOSTED_BASE into PGO instrument + train + optimized rebuild, but the downstream bolt job's rebuild step (lines 453–475) omits HOSTED_BASE. bolt only runs on workflow_dispatch today (where hosted_base defaults to ""), so release artifacts are unaffected, but forwarding HOSTED_BASE: ${{ inputs.hosted_base }} in bolt avoids producing an unconfigured binary if a manual dispatch supplies both run_bolt: true and hosted_base.

Nitpicks

  • to-dos/plans/v3.4.1-plan.md: Rows 10b, 10c, and 10e still carry pre-completion status text (Compiling 2026-10-18 (BUILD_DATE 261018), Pending: after the oracle merges) while .github/release-notes/v3.4.1.md and docs/STATUS.md record the finished 2026-10-19 (BUILD_DATE 261019) digests.
  • the_hosted_worker_names_the_workspace_version in crates/rustynes-test-harness/tests/release_anchor_audit.rs: Matching multi-line string literals with hardcoded 2-space and 6-space indentation against services/hosted/package.json and services/hosted/package-lock.json is coupled to exact JSON formatting and key ordering (npm lockfile regeneration or formatter changes will trip the assertion even if the version matches).

Antigravity review (Gemini via Ultra)

Cuts the v3.4.1 "Beacon" release, wiring shipped CI builds to the live Cloudflare hosted netplay lobby (with hosted TURN and RA proxying disabled), adding Durable Object alarm-driven TURN credential revocation, fixing the PGO release workflow from overwriting the full-featured binary during Stage 4 tests, fixing browser rcheevos ES-module bundling in Trunk, and converting the PPU emphasis delta table from an include!d array literal to a module.

Blocking issues

None found.

Suggestions

  • services/hosted/src/budget.ts: alarm captures const now = Date.now() at line 330 before await this.revokeDue(now) at line 350. Because revokeDue performs up to 50 sequential outbound fetch calls (with REVOKE_TIMEOUT_MS = 5000 ms each), wall-clock time can advance by seconds while Durable Object input gates are open across network I/O. Re-reading Date.now() after revokeDue finishes prevents nextRevocation (Math.max(parseRevokeKey(k).dueMs, now + 1000)) from scheduling an alarm timestamp that is already in the past when revokeDue takes over 1 second.
  • services/hosted/src/budget.ts: revokeDue calls this.ctx.storage.list<Revocation>({ prefix: REVOKE_PREFIX }) without a limit, loading every queued revocation record from storage even though keys are sorted chronologically and the loop always stops at REVOKE_BATCH (50). Pass { prefix: REVOKE_PREFIX, limit: REVOKE_BATCH } to bound storage reads per alarm.
  • android/app/src/main/res/values/strings.xml, android/app/src/main/res/values-es/strings.xml, and ios/RustyNES/SettingsView.swift: The hosted-mode UI copy tells users that leaving the TURN fields empty uses "the RustyNES hosted lobby and relay by default" / "short-lived credentials from the RustyNES hosted service", but services/hosted/wrangler.jsonc ships with TURN_ENABLED: "false" (so /v1/turn/credentials returns 503 turn-disabled and sessions fall back to direct STUN unless the user supplies a custom TURN server). Consider clarifying the hint text so users behind strict NATs do not expect hosted TURN relaying to be active.
  • android/app/src/main/java/com/doublegate/rustynes/Netplay.kt: RELAY_URL (Regex("^wss?://[^/\\s?#]+.*$")) only rejects whitespace in the authority segment, allowing spaces in the path/query (.*$) or hostless port-only strings like wss://:8080. Using \\S*$ for the remainder or validating URI(u).host != null would match the stricter check added in ios/RustyNES/NetplayModel.swift.

Nitpicks

  • ios/RustyNES/NetplayModel.swift: Foundation's URL.scheme preserves input casing; use scheme.lowercased() == "ws" || scheme.lowercased() == "wss" in onlineNetplayConfigured.
  • services/hosted/src/budget.ts: revokeKey and parseRevokeKey rely on a fixed 15-character timestamp width (rest.slice(0, 15) / rest.slice(16)); applying Math.trunc(dueMs) inside revokeKey guards against non-integer timestamps shifting the slice offset.

Cuts the v3.4.1 "Beacon" release, wiring the deployed Cloudflare hosted netplay base URL (RUSTYNES_HOSTED_BASE) into CI release workflows and mobile settings UIs, adding Durable Object alarm-driven TURN credential revocation (with TURN and the RA proxy disabled in wrangler.jsonc), fixing browser rcheevos packaging and Linux PGO artifact preservation, converting the PPU emphasis delta table from an include! expression to a Rust module, and bumping workspace/toolchain/npm dependencies to v3.4.1 and Rust 1.99.1.

Blocking issues

None found.

Suggestions

  • Documentation drift on TURN revocation retry policy — services/hosted/README.md states that "a failed revocation is retried every 5 minutes, six attempts in all", whereas REVOKE_GIVE_UP_MS and Budget.revokeDue implement exponential backoff (5 minutes doubling up to 1 hour) for up to 48 hours past firstDue (and retry hourly without incrementing attempts on 401/403). Update the README to match the implemented retry and give-up policy.
  • Stale now timestamp across network I/O in Budget.alarm — const now = Date.now() is captured once before await this.revokeDue(now). Because revokeDue processes up to REVOKE_BATCH = 50 credentials sequentially with a 5-second timeout each (REVOKE_TIMEOUT_MS = 5000), slow or timing-out upstream calls can advance wall-clock time significantly before revokeDue returns. Re-keying retry entries against the pre-batch now, floor-clamping nextRevocation(now) to now + 1_000, and checking pending > now against the pre-batch timestamp can compare against a timestamp well in the past and ignore a newly scheduled alarm or schedule an alarm in the past. Refresh Date.now() per retry and after await this.revokeDue(...) completes.
  • Delete-before-put order when re-keying failed revocations in Budget.revokeDue — await this.ctx.storage.delete(key) runs before await this.ctx.storage.put(revokeKey(now + delay, username), ...). Since now + delay > attemptAt guarantees the new key differs from key, writing the new key before deleting the old key avoids losing a pending revocation if the Durable Object is evicted or throws between the two storage operations.
  • Stale non-hosted Android hint copy after clearing the default signaling URL — Settings.npSignalingUrl now defaults to "" and normalizes any stored NetplayEndpoints.SIGNALING_URL placeholder to "". On builds without a compiled-in hosted base (!npHostedAvailable(), such as F-Droid or local source builds), NetplaySection still displays R.string.settings_netplay_online_hint in values/strings.xml and values-es/strings.xml ("The default URL is a placeholder — set your hosted signaling relay to enable it"), and the comment at Settings.kt still says the field defaults to the placeholder URL even though the field is now blank.

Nitpicks

  • Mobile TURN settings hints imply hosted TURN is active while TURN_ENABLED is "false" — values/strings.xml ("Room-code play uses the RustyNES hosted lobby and relay by default") and SettingsView.swift ("Leave all three empty to use short-lived credentials from the RustyNES hosted service") imply hosted TURN relay credentials are used when fields are blank, whereas TURN_ENABLED is deployed off in v3.4.1 so blank TURN settings fall back to STUN/direct-only.
  • Status table date drift in to-dos/plans/v3.4.1-plan.md — Row 10c still says Compiling 2026-10-18 (BUILD_DATE 261018) and row 10e says Pending, whereas .github/release-notes/v3.4.1.md records the final bitstreams as built on 2026-10-19 (BUILD_DATE 261019).

This PR cuts release v3.4.1 "Beacon", pointing shipped desktop, web, Android, and iOS builds at the deployed Cloudflare Worker netplay lobby (RUSTYNES_HOSTED_BASE), adding Durable Object alarm-driven TURN credential revocation at TTL expiry (with hosted TURN and RA proxy disabled in config), fixing browser rcheevos ES6 module packaging and Linux PGO release artifact uploads, converting the PPU emphasis table from an include! expression to a module for CodeQL, and bumping workspace versions to 3.4.1 on Rust 1.99.1.

Blocking issues

  • Unexpanded [GATES] placeholder in the release notes override: v3.4.1.md leaves the literal placeholder [GATES] as the body of ## Verification. Because release-auto.yml copies .github/release-notes/v${version}.md verbatim into gh release create --notes-file (release-auto.yml), merging this branch as-is will publish [GATES] verbatim in the v3.4.1 GitHub Release notes.

Suggestions

  • Sequential timeout budget in Durable Object TURN revocation: In Budget::revokeDue (with constants at budget.ts), up to REVOKE_BATCH = 50 credentials are revoked sequentially via await this.revokeOne(username), each with REVOKE_TIMEOUT_MS = 5_000. If Cloudflare's revocation endpoint stalls or times out across a full batch, 50 * 5s = 250s of wall time can exhaust the Durable Object alarm invocation before Budget::alarm sweeps stale counter keys or reaches this.ctx.storage.setAlarm(next). Bound concurrency (or reduce REVOKE_BATCH) and ensure setAlarm is re-armed in a finally block even if batch processing aborts early.
  • Mobile settings copy claims hosted TURN is active by default while TURN_ENABLED is "false": wrangler.jsonc sets "TURN_ENABLED": "false", so /turn/credentials returns 503 turn-disabled and clients fall back to STUN-only. However, SettingsView.swift ("Leave all three empty to use short-lived credentials from the RustyNES hosted service"), strings.xml ("Room-code play uses the RustyNES hosted lobby and relay by default"), and strings.xml (es) tell users that leaving the TURN fields empty uses the hosted relay. Clarify in those strings that only signaling/STUN is hosted by default unless a custom TURN server is entered.
  • Missing inline signaling URL scheme warning in Android SettingsSheet: onlineNetplayConfigured now rejects a non-empty npSignalingUrl unless it starts with ws:// or wss://. Unlike SettingsView.swift, which shows an inline warning directly beneath the text field in Settings, Android's SettingsSheet provides no validation feedback where the URL is edited.

Nitpicks

  • README.md and README.md: Line 75 still lists TURN_ENABLED ("true") as the default in wrangler.jsonc (now "false"), and line 99 states failed TURN revocations are "retried every 5 minutes, six attempts in all", whereas Budget::revokeDue uses exponential backoff (5 min doubling to 1 h) for up to 48 h (REVOKE_GIVE_UP_MS).
  • v3.4.1-plan.md: Rows 9 and 10c still contain pre-completion status text ("the compile and the script run are the gate" and "Compiling 2026-10-18 (BUILD_DATE 261018)"), whereas CHANGELOG.md and v3.4.1.md record the finished 2026-10-19 (BUILD_DATE 261019) build and release-rbf.sh pass.

Cuts the v3.4.1 "Beacon" patch release, wiring the deployed hosted netplay/TURN Worker URL into CI release builds (including preserving the full PGO binary across the test stage), fixing browser RetroAchievements packaging and CodeQL extraction of the PPU emphasis table, and refreshing workspace and hosted-service dependencies.

Blocking issues

None found.

Suggestions

  • android/app/src/main/java/com/doublegate/rustynes/Netplay.kt (with onlineNetplayConfigured and Settings.kt): In builds where npHostedAvailable() is true, onlineConfigured is false only when the user enters a non-empty signaling URL that does not start with wss:// or ws://. However, NetplaySheet still displays "Online play requires a relay server. None is configured yet, so only LAN works until one is set in Settings → Netplay (online).", and SettingsSheet shows no validation warning on npSig. Branching on npHostedAvailable() here (and in SettingsSheet), as NetplayModel.swift and SettingsView.swift do on iOS, would match the claim in CHANGELOG.md that both apps explain that clearing the field returns to the hosted lobby.
  • crates/rustynes-frontend/web/cheevos/ra_glue.js: rcheevosBase() passes the <meta name="rustynes-rcheevos-base"> attribute directly into new URL(...) without a try/catch. Unlike resolveProxyBase(), a malformed meta tag value (or calling rcheevosBase() with a relative path when both document.baseURI and location.href are undefined) will throw an unhandled TypeError instead of falling back to "cheevos/".

Nitpicks

  • crates/rustynes-test-harness/tests/release_anchor_audit.rs and scripts/release-automation/bump_release.py: Matching multi-line substrings with literal \n against services/hosted/package.json and services/hosted/package-lock.json is sensitive to CRLF checkouts on Windows if core.autocrlf is enabled.

This PR cuts the v3.4.1 "Beacon" patch release, wiring the deployed Cloudflare hosted netplay/TURN Worker (RUSTYNES_HOSTED_BASE) into the shipped CI/release workflows and mobile UI gates, fixing browser RetroAchievements (rcheevos) WASM/ES-module packaging and trunk feature-flag overrides, switching MiSTer release asset names to versioned tags, and refreshing Cargo, npm, Python, and GitHub Actions dependencies.

Blocking issues

None found.

Suggestions

  • Android Settings UI still pre-populates the signaling text field with the literal placeholder URL: In Settings.kt and SettingsSheet, settings.npSignalingUrl still defaults to NetplayEndpoints.SIGNALING_URL ("wss://relay.rustynes.example") and binds that string as the editable value of the OutlinedTextField. Although userSignalingUrl now maps that exact string to "", a user opening Settings on a hosted-enabled build sees "Room-code play uses the RustyNES hosted lobby and relay by default. Enter your own signaling relay or TURN server only to replace them" right above a text field already filled with "wss://relay.rustynes.example". If they partially edit or accidentally modify that text without clearing it completely, userSignalingUrl treats the modified string as a custom override and breaks hosted matchmaking. Consider initializing npSig from userSignalingUrl(settings) (or defaulting npSignalingUrl to "") and rendering NetplayEndpoints.SIGNALING_URL via the OutlinedTextField's placeholder parameter instead, matching NetplaySettingsView on iOS.
  • Scheme validation asymmetry between Android and iOS signaling URL checks: On iOS, NetplayModel.signalingConfigured only falls back to npHostedAvailable() when the trimmed URL is empty, and requires ws:// or wss:// when non-empty. On Android, onlineNetplayConfigured evaluates userSignalingUrl(settings).isNotEmpty() || npHostedAvailable(), which neither validates ws:///wss:// on a custom URL nor warns when a non-empty custom URL is malformed on a build with npHostedAvailable() == true. Aligning onlineNetplayConfigured with iOS (if empty, npHostedAvailable(); otherwise check ws:// or wss://) would catch scheme typos before attempting to host or join.

Nitpicks

  • NetplayModel.signalingHint and the warning Label in NetplaySettingsView: when npHostedAvailable() is true and the user has typed an invalid non-empty signalingURL, the error/warning text still says only to enter a wss:// URL rather than noting that clearing the field restores the RustyNES hosted lobby.
  • every_shipped_build_compiles_the_same_hosted_base: rest.trim().trim_matches('"') only strips double quotes and does not strip trailing YAML inline comments (# ...) or single quotes if a workflow line is reformatted later.

This PR cuts release v3.4.1 ("Beacon"), wiring the deployed Cloudflare Worker base URL (https://rustynes-hosted.parobek.workers.dev) into the release/mobile/web build workflows, adding np_hosted_available to the mobile FFI so Android and iOS enable room-code netplay without a user-supplied signaling URL when a hosted base is compiled in, fixing the browser rcheevos.js ES6 module build and base-path resolution in ra_glue.js, disabling the Worker's RetroAchievements proxy by default in wrangler.jsonc, and bumping the workspace to v3.4.1 on Rust 1.99.1.

Blocking issues

  • Stage 4 in pgo.yml overwrites the PGO-built rustynes binary without RUSTYNES_HOSTED_BASE (and without --features full) before Stage 6 packages it for release.
    • In pgo.yml, RUSTYNES_HOSTED_BASE is exported only inside the Stage 2 run: step (PGO instrument + train + optimized rebuild), rather than at the workflow/job env: level.
    • Stage 4 (Determinism oracle (test-roms, PGO-optimized codegen), pgo.yml) then executes cargo pgo optimize test -- --workspace --release --features test-roms in a new shell where RUSTYNES_HOSTED_BASE is unset.
    • Because rustynes-frontend has an integration test (no_bare_fs_write.rs), Cargo compiles the [[bin]] name = "rustynes" target during cargo test --workspace --release to provide CARGO_BIN_EXE_rustynes. With RUSTYNES_HOSTED_BASE unset in Stage 4 (and --features full absent), Cargo invalidates BUILD_HOSTED_BASE (option_env!("RUSTYNES_HOSTED_BASE")) and rebuilds target/${{ matrix.triple }}/release/rustynes with BUILD_HOSTED_BASE = None, overwriting the Stage 2 binary right before Stage 6 archives and uploads it to release.yml as the promoted Linux x86_64 release artifact.
    • Set RUSTYNES_HOSTED_BASE in job- or workflow-level env: in pgo.yml (including the bolt job at pgo.yml), and ensure Stage 4 either does not overwrite the --features full release binary or rebuilds rustynes-frontend after the workspace test run.

Suggestions

  • Tighten the CI workflow audit in release_anchor_audit.rs: every_shipped_build_compiles_the_same_hosted_base only checks that pgo.yml contains the substring "RUSTYNES_HOSTED_BASE", which allowed the single-step export bug above to pass. Assert that pgo.yml sets RUSTYNES_HOSTED_BASE in workflow/job env: (or across every cargo pgo invocation) just as release.yml, android.yml, ios.yml, and web.yml do.
  • Validate scheme in Android's onlineNetplayConfigured and update the Android Settings hint/field default (Netplay.kt, Settings.kt, strings.xml):
    • Unlike iOS's NetplayModel.signalingConfigured, which requires wss:// or ws:// when a custom URL is entered, Android's onlineNetplayConfigured(settings) accepts any non-empty string other than NetplayEndpoints.SIGNALING_URL.
    • In Settings.kt and strings.xml, the text field is still pre-populated with the literal value "wss://relay.rustynes.example" and settings_netplay_online_hint still tells the user "Room-code play needs a relay server. The default URL is a placeholder — set your hosted signaling relay to enable it", contradicting the new out-of-the-box hosted behavior when npHostedAvailable() is true.
  • Update the iOS Settings footer when npHostedAvailable() is true (SettingsView.swift): Line 352 changes the section header to "Signaling relay (optional)", but the footer on line 356 still unconditionally states "The maintainer must deploy and host it (a documented carryover mirroring the Android deploy bundle)."

Nitpicks

  • release_anchor_audit.rs: the_hosted_worker_names_the_workspace_version matches multi-line substrings in services/hosted/package.json and services/hosted/package-lock.json using literal \n line endings ("\"name\": \"rustynes-hosted\",\n \"version\": \"{v}\""), which will fail on CRLF checkouts if \r\n is not normalized first.

Antigravity review (Gemini via Ultra)

Cuts release v3.4.1 ("Beacon"), wiring the compiled-in hosted service base URL across release workflows and mobile room-code netplay UIs, fixing browser RetroAchievements ES6/WASM asset loading, disabling the hosted RA proxy by default in Wrangler config, and bumping toolchain and dependency pins.

Blocking issues

None found.

Suggestions

  • Android onlineNetplayConfigured neither validates WebSocket schemes nor disables the room-code action buttons: In Netplay.kt, onlineNetplayConfigured accepts any non-empty string from userSignalingUrl without checking for a ws:// or wss:// scheme (unlike iOS NetplayModel.signalingConfigured), and NetplaySheet only hides the warning text when onlineConfigured is false rather than gating enabled on the "Host room" (line 249) and "Join" (line 272) buttons. This also contradicts the new doc comment on np_hosted_available, which states that Android disabled the room-code buttons.
  • RUSTYNES_HOSTED_BASE is only exported in Stage 1/2 of pgo.yml, not across subsequent cargo invocations or the bolt job: In pgo.yml, RUSTYNES_HOSTED_BASE is set only on the "PGO instrument + train + optimized rebuild" step. Step "Stage 4 — Verify PGO binary passes tests" (line 206, cargo pgo optimize test) and the bolt job (line 242) run without RUSTYNES_HOSTED_BASE in env:, which invalidates Cargo's option_env!("RUSTYNES_HOSTED_BASE") fingerprint for rustynes-netplay and causes Stage 4 / bolt to rebuild against an unset hosted base. Hoist RUSTYNES_HOSTED_BASE: ${{ inputs.hosted_base }} to the job- or workflow-level env:.
  • Unhandled new URL(...) failure in rcheevosBase: Unlike resolveProxyBase in the same file, rcheevosBase does not guard document.querySelector or new URL(raw, base) in a try / catch. If <meta name="rustynes-rcheevos-base"> contains a malformed URL or both document?.baseURI and location?.href are undefined in a non-DOM test environment, new URL(...) throws a synchronous TypeError before ensureModule returns a rejected promise.
  • Android Settings still pre-fills the dead placeholder URL wss://relay.rustynes.example: userSignalingUrl silently maps NetplayEndpoints.SIGNALING_URL to "", but AppSettings.npSignalingUrl and SettingsSheet still initialize and display "wss://relay.rustynes.example" as the active text field value alongside the pre-v3.4.1 hint saying only LAN netplay works until the maintainer sets a URL.

Nitpicks

  • SettingsView.swift: The section header switches to "Signaling relay (optional)" when npHostedAvailable() is true, but the footer on line 353 still states "The maintainer must deploy and host it (a documented carryover mirroring the Android deploy bundle)."
  • release_anchor_audit.rs: every_shipped_build_compiles_the_same_hosted_base only checks substring presence of RUSTYNES_HOSTED_BASE and the expected URL anywhere in each workflow file; it would still pass if pgo.yml fails to forward the input or if a workflow defines the variable in a comment or unrelated step.

Antigravity review (Gemini via Ultra)

This PR wires the deployed Cloudflare Worker (RUSTYNES_HOSTED_BASE) into the Web, desktop release, Android, and iOS CI workflows, fixes three packaging bugs that prevented the browser RetroAchievements build from loading rcheevos.wasm, disables the live RA proxy until upstream approval (RA_ENABLED = "false"), and updates documentation and the v3.4.1 release plan.

Blocking issues

  1. Promoted PGO Linux release binary drops RUSTYNES_HOSTED_BASE (.github/workflows/release.yml:54-60, .github/workflows/release.yml:267-299, .github/workflows/pgo.yml:85-90, scripts/pgo/run.sh:42):
    release.yml sets RUSTYNES_HOSTED_BASE in its workflow-level env:, which applies to the initial build job. However, the pgo job invokes uses: ./.github/workflows/pgo.yml (workflow_call), and GitHub Actions does not inherit workflow-level env: across reusable workflow calls. Because pgo.yml does not set RUSTYNES_HOSTED_BASE, whenever the PGO gate passes (promotable == 'true'), pgo-linux-asset overwrites (gh release upload --clobber) the Linux release archive with the PGO binary compiled by pgo.yml where BUILD_HOSTED_BASE is None. (If adding RUSTYNES_HOSTED_BASE to pgo.yml, scope it to the PGO instrument + train + optimized rebuild step rather than workflow-wide so Stage 4's cargo pgo optimize test still runs a_stock_build_has_no_hosted_base in crates/rustynes-netplay/src/hosted.rs:877.)

  2. Incomplete release cut for release: v3.4.1 "Beacon" (CHANGELOG.md:27, services/hosted/wrangler.jsonc:72, to-dos/plans/v3.4.1-plan.md:41-48):
    services/hosted/wrangler.jsonc bumps RA_USER_AGENT to 3.4.1, but CHANGELOG.md still has the v3.4.1 notes under ## [Unreleased], [workspace.package] version in Cargo.toml and all release anchors remain at 3.4.0, and rows 3, 9, and 10 in to-dos/plans/v3.4.1-plan.md are still marked Pending ("run BEFORE the release PR merges"). Merging before running bump_release.py and cutting the ## [3.4.1] changelog section will cause release-auto.yml to see existing tag v3.4.0 and exit without cutting v3.4.1.

Suggestions

  1. Track services/hosted/wrangler.jsonc in bump_release.py and release_anchor_audit.rs (services/hosted/wrangler.jsonc:70-72, scripts/release-automation/bump_release.py:71-78):
    The comment in wrangler.jsonc states "Bump the product and rcheevos versions with each release" for RA_USER_AGENT, but services/hosted/wrangler.jsonc is not in MANIFESTS in bump_release.py or audited in crates/rustynes-test-harness/tests/release_anchor_audit.rs, so future automated version bumps will leave RA_USER_AGENT on an old version.

  2. Trim <meta name="rustynes-rcheevos-base"> and deduplicate in-flight loadModule() calls (crates/rustynes-frontend/web/cheevos/ra_glue.js:115-131):

    • In rcheevosBase(), meta?.getAttribute("content") is not .trim()med (unlike resolveProxyBase() at line 62). Leading/trailing or whitespace-only content values will cause raw.endsWith("/") to append "/" after the whitespace and produce a broken module URL.
    • In loadModule(), _module is assigned only after both awaits resolve; if ra_init() and ra_rcheevos_version() are invoked concurrently before initialization finishes, both will import and instantiate separate rcheevos.wasm instances. Caching the in-flight promise avoids double instantiation.
    • Exporting rcheevosBase alongside resolveProxyBase would allow covering it in services/hosted/test/ra-glue.test.ts.

Nitpicks

  • .github/workflows/android.yml:69 / CHANGELOG.md:33: Because RUSTYNES_HOSTED_BASE is set at the workflow level in android.yml, the CI-built bundleFossRelease artifact (android.yml:342) also compiles with the hosted base; only external source builds (such as F-Droid's own build servers running Gradle outside GitHub Actions) omit it.

Folds in the three open Dependabot PRs (#614 cosim sha2 0.11.1, #615
sharp 0.35.5, #616 the production-dependencies group) and takes the rest
of the tree to its newest compatible versions, checked rather than
assumed:

- Cargo: `cargo update` on the workspace (43 packages, among them sha2
  0.11.1, tokio 1.53.3, serde_json 1.0.154, proptest 1.12.0, cc 1.8.0,
  arboard 3.7.0, uuid 1.28, zip 9.0.5) and on rustynes-cosim; libc's
  requirement raised to 0.2.191 in rustynes-cheevos and
  rustynes-libretro, the only direct requirement `cargo upgrade
  --incompatible allow` found behind. `cargo update --verbose` holds
  four transitive packages, none ours to move: getrandom 0.2 and 0.3
  (the deliberate wasm32 shims in rustynes-frontend), generic-array
  0.14.9 and psm 0.1.32 (newer releases need a newer rustc than the
  MSRV-aware resolver allows). wasm-bindgen stays 0.2.129, equal to the
  Trunk.toml CLI pin.
- Rust 1.99.0 -> 1.99.1 (rust-toolchain.toml and .gitlab-ci.yml's
  RUSTUP_TOOLCHAIN together; every buildbot job runs `rustup toolchain
  install`, so a patch move needs nothing from the image). rust-version
  stays "1.99".
- dtolnay/rust-toolchain 7e38f4b4 -> 683b588c (refs/tags/v1). The four
  commits were read, as rust-setup's comment requires: `${{ }}`
  interpolations into run scripts moved into env variables (closing a
  script-injection path), the flag step folded into a bash array, 1.99.1
  in the patch table. taiki-e/install-action 2.87.28 -> 2.87.29; every
  other action's floating major already resolves to its newest release.
- Hosted Worker: TypeScript 5.9.3 -> 7.0.2, vitest 4.1.11 -> 5.0.5,
  @cloudflare/vitest-plugin 1.4.4 (peer: vitest ^4.1 || ^5),
  workers-types 5.20261019.1 (wrangler 4.151.1 wants >= 5.20261006.1),
  wrangler 4.151.1; package version 3.4.1. npm audit: 0
  vulnerabilities. `wrangler deploy --dry-run` bundles (37.45 KiB).
- ruff-pre-commit v0.16.10 -> v0.17.1 (passes on the repo).
- MkDocs on Python 3.15 (3.15.0 released 2026-10-09): verified first in
  a scratch venv, mkdocs-material[imaging] installs from wheels (Pillow
  13.0.0) and `mkdocs build --strict` completes with no warning.

Held, with reasons: Node 24 (26 becomes LTS on 2026-10-28), JDK 25 (the
current LTS; 27 is not), NDK r30 16248370 (already newest). Android
(Gradle 9.8.1, AGP 9.4.1, Kotlin 2.4.21, Compose BOM 2026.09.00, every
androidx and Play artifact) was already at its newest stable releases.

Verified on 1.99.1: fmt; clippy -D warnings for the workspace, the
scripting / hd-pack / retroachievements / full feature sets, both
wasm32 targets and rustynes-cosim; the thumbv7em no_std build; rustdoc
-D warnings; cargo test --workspace 3,183 passed / 0 failed / 9
ignored; the Worker's 114 tests and tsc.

Codex and Copilot on #618: baking RUSTYNES_HOSTED_BASE into the Android
and iOS CI builds made no difference to a fresh install, because both
apps stopped short of the bridge. NpNetConfig::to_nat_config substitutes
the hosted lobby only for an EMPTY signaling URL, and:

- Android's Settings default is the placeholder
  `wss://relay.rustynes.example`. netplayConfig() forwarded it
  (non-empty, so never substituted) and MainActivity disabled room-code
  play on it.
- iOS's `signalingConfigured` accepted only an explicit ws:// or wss://
  URL, so NetplayView disabled both room buttons and hostRoom/joinRoom
  returned before reaching the bridge.

The fix gives the shells the fact they lacked:

- rustynes-mobile exports `np_hosted_available()` (true exactly when
  `hosted::resolve_base("")` finds a compiled-in base); UniFFI makes it
  `npHostedAvailable()` in Kotlin and Swift. Test:
  hosted_availability_follows_the_compiled_base pins it to
  BUILD_HOSTED_BASE.
- Android: `userSignalingUrl()` maps the placeholder (and blank) to "no
  override", so the bridge fills in the hosted lobby; any other value is
  the user's relay and wins. `onlineNetplayConfigured()` = a user relay
  OR a compiled-in base, replacing MainActivity's inline check.
- iOS: an empty URL counts as configured when npHostedAvailable(); an
  explicit URL is still checked for a WebSocket scheme. The Settings
  header reads "(optional)" in such a build.

A build without a base (F-Droid, plain source) behaves exactly as
before: the placeholder still means unconfigured and the caveat shows.

Verified: clippy and rustdoc clean for rustynes-mobile; its five hosted
tests pass. NOT compiled here: the Kotlin and Swift halves (no Xcode on
Linux). android.yml builds the Kotlin on the PR; ios.yml is dispatched
once on this branch before merge to compile the Swift (a one-time check
at the maintainer's direction; Apple runs are not a default).

agy on #618, on the v3.4.1 glue change:

- rcheevosBase() did not trim the `rustynes-rcheevos-base` meta value
  (resolveProxyBase() trims its own). A value with surrounding spaces
  produced a URL with the spaces in it, and a whitespace-only value was
  taken as a base. It is trimmed now, and blank falls back to `cheevos/`.
- loadModule() cached only the finished module, so ra_init() and
  ra_rcheevos_version() called before the first load finished each
  imported and instantiated their own rcheevos.wasm. The in-flight
  promise is cached; a failed load clears it so a later call can retry.
- rcheevosBase is exported, and services/hosted/test/ra-glue.test.ts
  covers it with a stubbed `document` (the Workers runtime has no DOM):
  the default resolves against the page, not the snippet; the meta value
  is trimmed and given a trailing slash; a blank value counts as absent.
  Mutation: `.trim()` removed -> 2 of the new tests fail.

Verified: the Worker suite 114 passed, tsc (TypeScript 7.0.2) clean.

- .github/release-notes/v3.4.0.md (CodeRabbit): the "Two builds" line
  named the date-coded files without saying where they live; it now says
  MiSTer's updater installs them from the RustyNES_MiSTer repository's
  `releases/`, and that the attached files carry the same bytes under
  version names. The live v3.4.0 release body was updated from the file.
- docs/cheevos-browser.md:200 (CodeRabbit, outside the diff): the step
  told maintainers to set `RA_PROXY_BASE` in ra_glue.js, which no longer
  exists as a setting; it now names the `rustynes-ra-proxy-base` meta tag
  that resolveProxyBase() reads.
- to-dos/plans/v3.4.1-plan.md (CodeRabbit): row 10 split into 10a-10e so
  the waived checks read as waived (the seed sweep skipped and the
  ladders not waited for, both by the maintainer on 2026-10-18) and the
  remaining ones (one compile per build, VERIFY=1 at the new pin) carry
  their own status; rows 12-14 record the mobile, PGO and dependency
  work.
- CHANGELOG: the Added entry now says the profile-guided Linux binary
  and every CI-built Android artifact (the FOSS flavour too, agy's
  nitpick) carry the base, and that a fresh mobile install can host and
  join; a Changed entry records the dependency sweep.

markdownlint passes on every file.

Copilot and Antigravity on #618: release.yml set RUSTYNES_HOSTED_BASE in
its workflow-level env, but its `pgo` job calls the reusable pgo.yml,
and a called workflow inherits no `env:`. When the PGO gate promoted,
pgo-linux-asset replaced the Linux release archive (`--clobber`) with a
binary compiled without the base, silently dropping the hosted lobby
from the one platform whose binary is rebuilt.

- pgo.yml's workflow_call gains a `hosted_base` input (default empty),
  exported as RUSTYNES_HOSTED_BASE for the instrument/train/rebuild step
  only, and only when non-empty (an empty string would reach option_env!
  as a value). The dispatch-only BOLT job is unchanged.
- release.yml passes the URL as a literal: `env` is not an allowed
  context in a reusable workflow's `with:`.

Two literals that must agree are a drift waiting to happen, so
release_anchor_audit gains:

- every_shipped_build_compiles_the_same_hosted_base: web, release,
  android and ios set RUSTYNES_HOSTED_BASE exactly once, release.yml
  passes hosted_base exactly once, all name the same https URL, pgo.yml
  exports the input, and ci.yml sets none (a_stock_build_has_no_hosted_base
  asserts the default only when the variable is absent). Mutation: the
  PGO literal changed to another host -> FAILED; restored -> 18 passed.
- the_hosted_worker_names_the_workspace_version (agy's suggestion):
  wrangler.jsonc's RA_USER_AGENT, package.json's root and both
  package-lock root entries name the workspace version. bump_release.py's
  MANIFESTS now moves all four (each pattern matches exactly once; the
  lockfile entries carry the name line, since a bare "version" matches
  dependencies too). --selftest passes.

actionlint passes on both workflows.

doublegate and others added 4 commits October 19, 2026 15:54
The v3.4.1 live expiry gate failed (T-HOSTED-TURN-EXPIRY). The Worker
asks Cloudflare for credentials with {"ttl": 10800}, and Cloudflare's
generate-credentials page says the ttl expires the credential and its
FAQ that an expired allocation is disconnected "after a short delay".
Measured on 2026-10-19 with relay-only ICE gathers in fresh Chromium
profiles, it does not refuse them: a 3-hour credential 2 h 38 min past
its expiresAt, and a 600 s credential (minted on a briefly redeployed
Worker, production restored within the minute) 6.6 minutes past its
own, both still obtained `relay udp` candidates. The spend guards bound
how many credentials exist; nothing bounded how long a leaked one
worked. The maintainer chose to fix it in v3.4.1 rather than ship it as
a known issue.

The Worker now enforces the TTL itself:

- handleTurn hands every TURN username in the minted ICE list to the
  global Budget object with its expiry (expiresAt * 1000).
- Budget.scheduleRevoke stores `revoke:<due ms, 15 digits>:<username>`
  (keys sort by due time, and survive eviction) and pulls the object's
  single alarm in to the due time if it was later.
- The alarm now revokes due credentials before its hourly sweep:
  POST rtc.live.cloudflare.com/v1/turn/keys/<id>/credentials/<user>/revoke
  with the key's token. 204 (and 404, which means Cloudflare no longer
  knows it) deletes the entry; anything else is retried every 5 minutes,
  REVOKE_MAX_ATTEMPTS (6) attempts in all, then dropped rather than
  retried forever. At most 50 per alarm, so one alarm stays short; the
  rest follow a second later. The alarm re-arms for the earlier of the
  next sweep and the next revocation.
- A failed mint schedules nothing. Revocation is never earlier than the
  TTL, so a session within its three hours is untouched.

Tests (TDD: the four new behaviours failed first): scheduling at
expiry, nothing on a failed mint, revoking only due credentials with
the bearer token and re-arming for the next one, a 404 as done, retry
then give-up. Mutations: the scheduling call removed -> 1 fails; the
re-arm ignoring the next revocation -> 2 fail. 119 passed; tsc
(TypeScript 7.0.2) clean.

PRIVACY.md now says the service keeps each credential's username (a
random identifier Cloudflare issues, not linked to the user or their
address) until the TTL ends, then revokes it and deletes the username;
the secret half is never stored. The README's guard table, its "Why 3
hours", backstop and live-gate steps, and turn.ts's TTL comment say the
TTL is enforced by revocation and why.

Not covered: credentials minted before this deploy (yesterday's gates
and today's two tests) are not in the schedule and stay usable until
whatever limit Cloudflare applies; none was shared beyond this machine.
The live re-run of the expiry gate follows the deploy.

The automated security review of 960ff9f raised two findings; both
hold.

1. Fail-open retries. A missing key, a 401 or a 403 used up the six
   attempts in 30 minutes and then deleted the revocation, and a 404
   was accepted as done with no trace, so a token rotated or revoked
   by mistake would have let every credential minted meanwhile live
   on. Now:
   - 2xx: done. 404: done (Cloudflare does not know the credential),
     logged as a warning, because a 404 from a wrong key id would look
     the same.
   - Missing key / 401 / 403: a configuration fault, logged as an
     error, retried hourly WITHOUT counting as an attempt.
   - Anything else: backoff from 5 minutes, doubling to an hour.
   - An entry is dropped only REVOKE_GIVE_UP_MS (48 h, Cloudflare's
     maximum TTL) past the credential's expiry, with an error log.
   A retry is re-keyed under its next attempt time, so the key order
   stays the order of work; the value keeps `dueMs` (the original
   expiry) and the attempt count. Logs carry the status and attempt
   count only, never the username, and Workers Logs are off in
   production.

2. A delayed revocation. alarm() computed the next revocation before
   awaiting Cloudflare; a credential minted during those awaits set its
   own earlier alarm, which the final setAlarm then pushed later (up to
   the next hourly sweep, past a 600 s TTL). The re-arm now reads the
   first pending key fresh after the sweep, and keeps any alarm already
   set earlier.

Tests: backoff and re-keying, kept until 48 h past expiry and dropped
after, 401/403 retried hourly with attempts unchanged, and a credential
scheduled from inside the revoke call (a mint landing mid-alarm) keeping
its alarm. Mutations: the fresh re-arm read removed -> 1 fails;
configuration failures counted as attempts -> 1 fails. 121 passed; tsc
clean. Deployed (version 6496919c) ahead of the live expiry re-run.

Review of 148ee28 on #618:

- Cursor Bugbot (medium): f6cb343 made Android's
  onlineNetplayConfigured require a ws:// or wss:// relay, "matching
  iOS", but on Android it only chose the caveat text; the Host online
  and Join buttons still called the bridge with the malformed URL, and
  the caveat said "no relay is configured". Both buttons are now
  disabled while it is false, as iOS disables its room buttons, and in
  a build that carries the hosted lobby the caveat says the Settings URL
  is not a WebSocket address and that clearing it restores the hosted
  lobby. A build without a base keeps the old caveat.
- Antigravity (suggestion): rcheevosBase() passed the meta value
  straight to `new URL(...)`, so a malformed value threw out of
  ra_init. It now falls back to `cheevos/` beside the page, as
  resolveProxyBase() refuses a bad proxy base. New test: a value of
  "http://[bad" resolves to the default (122 passed).

Not changed: agy's nitpick that the package-version anchors in
release_anchor_audit and bump_release.py match "\n" and would miss on a
CRLF checkout. Both read files this repository stores with LF
(.editorconfig mandates LF), and a CRLF checkout makes the audit FAIL,
loudly, rather than pass wrongly.

Revocation (960ff9f, 2f78987) was deployed and tested live on
2026-10-19 with a 600 s credential and `wrangler tail` attached: the
Budget alarm fired at expiry and logged "turn revoke: 1 revoked" (a 2xx
from Cloudflare's revoke endpoint; a 404 would have logged its own
warning). Two minutes later the credential still obtained 8 `relay udp`
candidates in a fresh Chromium profile. So did the earlier 600 s
credential, revoked about 15 minutes before, and the 3-hour credential
from 14:35, expired since 16:35. The control: a credential with a
random username and password got NO relay candidate, so Cloudflare does
authenticate and the gather does distinguish. Cloudflare creates
allocations for credentials that are expired AND revoked, at least for
these intervals, contrary to its generate-credentials page and FAQ.
Its FAQ also says an expired credential stops being billed at once and
is disconnected shortly after; neither was measured.

The maintainer chose to ship with the relay off:

- wrangler.jsonc: TURN_ENABLED "false", with the reason at the site.
  Deployed (version 764bc2e4); POST /turn-credentials answers 503
  turn-disabled (after about 15 s of propagation, during which one
  credential was issued; it is scheduled for revocation and its
  response was not kept). Clients already treat turn-disabled as
  "connect directly (STUN only)".
- vitest.config.ts binds TURN_ENABLED "true", as for RA_ENABLED, so the
  TURN and revocation code stays under test (122 passed).
- budget.ts logs a count after a revocation pass ("turn revoke: N
  revoked"), no usernames, so an operator tailing the Worker can see it
  work; that line is how the 2xx above was established.
- Docs: the release headline in every anchor (AGENTS, README, ROADMAP,
  SUPPORT, OVERVIEW, VERSION-PLAN, STATUS, to-dos/ROADMAP, CHANGELOG),
  the CHANGELOG entry and the release notes say the lobby is live and
  the relay is deployed but off, and why; the Worker README gains "TURN
  is off"; plan row 3 records both failed gates; T-HOSTED-TURN-EXPIRY
  now lists what remains (measure billing and allocation lifetime,
  report to Cloudflare, switch back on).

Verified: release_anchor_audit 18, release_notes_render_audit 9 and
release_state_prose_audit pass; markdownlint passes on every changed
file.

Arm the sweep when the pending alarm is later than one hour.

This PR stops the alarm from being only the hourly sweep. scheduleRevoke (Line 234) and the alarm's re-arm (Lines 347-357) can now leave a single alarm set to a revocation due time. That time can be up to the TTL away: 3 h by default, and up to 24 h through TURN_TTL_SECONDS.

admit still arms the sweep only when getAlarm() returns null. Here is a trigger:

  1. The first alarm after midnight deletes yesterday's day: counter. No ip: window is left, so remaining is 0.
  2. The alarm is re-armed to a pending revocation, for example at 02:50.
  3. A new admission arrives at 00:40. It writes ip:<hash> and today's counter, sees an alarm that is not null, and does not set now + HOUR_MS.
  4. The salted IP hash then stays in storage until 02:50.

PRIVACY.md says this hash is kept "for at most two hours". With a long TTL, the gap is many hours. The same check also delays deletion of the previous day's counter.

Proposed fix
     await this.ctx.storage.put(writes);
-    if ((await this.ctx.storage.getAlarm()) === null) await this.ctx.storage.setAlarm(now + HOUR_MS);
+    const alarm = await this.ctx.storage.getAlarm();
+    if (alarm === null || alarm > now + HOUR_MS) await this.ctx.storage.setAlarm(now + HOUR_MS);
     return { ok: true, day, key };

Add a test for this case: seed a revocation 3 h out with no windows, admit once, and assert getAlarm() <= now + HOUR_MS.

CodeRabbit on d215275 (six inline, one outside the diff), all valid:

- budget.ts (outside the diff, CWE-359): admit() armed the hourly sweep
  only when no alarm was set. Since revocations share the object's one
  alarm, a pending revocation hours out could keep a salted IP hash past
  PRIVACY.md's "at most two hours". It now re-arms for the sweep when
  the set alarm is more than an hour away. Test (failed first): a
  revocation 3 h out, one admission, the alarm within the hour.
  123 passed.
- Netplay.kt / NetplayModel.swift: a bare "ws://" passed the prefix
  check and enabled room codes with no host. Android now requires
  `^wss?://` plus a host before any path; iOS parses with URL and
  requires a ws/wss scheme and a non-empty host. The Swift is not
  compiled here.
- services/hosted/README.md: every passage that said revocation bounds
  a credential now says it is attempted and that its effect is
  unverified (the guard table row, the revocation paragraph, "What the
  guards do not bound", the backstop step), the live-gate step says it
  still fails as of v3.4.1, the guard table shows the deployed
  TURN_ENABLED and RA_ENABLED values ("false"), and the retry policy
  is described as budget.ts implements it (2xx / 404 done, config
  errors hourly without counting, backoff 5 min doubling to 1 h, drop
  48 h past expiry).
- CHANGELOG: revocation described as requested, not effective.
- PRIVACY.md: the username retention states the 48 h worst case and the
  configurable lifetime (3 h deployed, up to 24 h), and that with the
  relay off nothing is kept; effective date 2026-10-19 (v3.4.1). The
  release notes state the change, as the policy itself requires.
- The release notes' iOS line also names the relay-URL check among the
  uncompiled Swift edits. The [GATES] finding was already fixed in
  d215275.

Also to-dos/mister/TASKS.md: T-MISTER-SS-ABANDON-STATES for v3.4.2,
Antigravity's blocking claim on sibling #67 read against the RTL (the
four unlisted states are safe as shipped; the comment is wrong and an
earlier abandon in E_PUT would keep the previous slot), deferred
because any rtl/ edit makes release-rbf.sh refuse the compiled
bitstreams.

Review round 3: replies to the findings that are not inline threads

CodeRabbit, outside the diff: budget.ts:210, arm the sweep when the pending alarm is more than an hour out (CWE-359). Valid, fixed in 631976e.

  • The problem: admit() armed the hourly sweep only when no alarm existed. Since revocations share the object's single alarm, a revocation hours out could keep a salted IP hash past PRIVACY.md's "at most two hours".
  • The fix: it now re-arms when the set alarm is more than an hour away.
  • The test, which failed first: a revocation 3 h out, one admission, and the alarm lands within the hour. 123 tests pass.

Antigravity, round on 148ee28 (no blocking issues).

  • Android room codes with an invalid relay: fixed in 1226b13 and 631976e. The buttons are disabled, the caveat says to clear the field, and a host is now required.
  • rcheevosBase() throwing on a malformed meta value: fixed in 1226b13. It falls back to cheevos/ and is tested.
  • Nitpick, \n-anchored package-version patterns would miss on a CRLF checkout: not changed. Both files are stored with LF (.editorconfig mandates LF). On a CRLF checkout the audit FAILS loudly; it doesn't pass wrongly.

TURN status since round 2. The relay ships switched off (641a815).

  • Live tests on 2026-10-19 found Cloudflare accepting new allocations for credentials past their expiry, and for credentials the Worker had revoked through Cloudflare's API. wrangler tail confirmed those revoke calls returned 2xx.
  • The control: a made-up credential is refused.
  • The Worker's revocation stays deployed and tested, and T-HOSTED-TURN-EXPIRY records the stricter test and the alternatives.

Answers Antigravity's latest #618 round (no blocking findings) and the
older round's copy note.

Worker (services/hosted/src/budget.ts):

- alarm() read `now` once and reused it after up to REVOKE_BATCH (50)
  revocation fetches, each bounded by REVOKE_TIMEOUT_MS. A slow batch
  could therefore schedule the next alarm, and judge the 48 h give-up,
  against a clock minutes stale. revokeDue now takes Date.now() after each
  revokeOne for the give-up and the retry time, and the alarm's final
  scheduling reads the clock again before nextRevocation().
- revokeDue listed every pending revocation key and stopped after a
  batch. The list is now bounded ({ prefix, limit: REVOKE_BATCH + 1 });
  keys sort by attempt time, so the first batch is the right one.
- A retry wrote the new key after deleting the old one. An eviction
  between the two lost the revocation; the order is now put then delete,
  whose worst case is one harmless duplicate revoke.
- revokeKey truncates the time before zero-padding, so a fractional
  millisecond can never widen the fixed 15-digit field and break the
  lexical order the list relies on.

TURN stays switched off in production (TURN_ENABLED "false"); this code
runs only when it is re-enabled, and vitest binds it on.

Mobile:

- Android RELAY_URL accepted "wss://:8080" (no host) and whitespace after
  the host. The host must now start with a non-colon character and no
  whitespace is allowed anywhere; case-insensitive. Checked: ws://,
  wss://:8080 and "wss://h/p q" refused; wss://relay.example,
  WSS://Relay.example/x and ws://10.0.0.2:9000 accepted.
- iOS compares the URL scheme case-insensitively.
- Copy no longer promises a hosted relay or short-lived TURN credentials
  while the relay is off (Android EN/ES hint, iOS TURN footer), and the
  non-hosted Android hint no longer calls the empty default a placeholder.

Verified: vitest 123 passed; tsc --noEmit clean. No Rust changed. The
Kotlin and Swift edits are uncompiled locally (no Android/iOS run for
this commit; the release runs ios.yml).

Review round 4: Antigravity's suggestions on 631976e

No blocking findings in that round. Every suggestion is answered in ce80d0f:

  • alarm() reuses a stale now across up to 50 revocation fetches. Valid. revokeDue takes Date.now() after each revokeOne for the 48 h give-up and the retry time, and the final scheduling reads the clock again before nextRevocation().
  • revokeDue lists every pending key. Valid. Now list({ prefix, limit: REVOKE_BATCH + 1 }); keys sort by attempt time, so the first batch is the right one.
  • Delete-before-put when re-keying a retry. Valid. Now put then delete: the worst case is a duplicate revoke, never a lost one.
  • revokeKey padding a fractional time. Valid. The time is truncated before padding.
  • RELAY_URL accepts wss://:8080 and whitespace. Valid. The host must start with a non-colon character, whitespace is refused anywhere, case-insensitive. Checked against ws://, wss://:8080, wss://h/p q (refused) and wss://relay.example, WSS://Relay.example/x, ws://10.0.0.2:9000 (accepted).
  • iOS scheme comparison is case-sensitive. Valid, now lowercased.
  • Copy promises a hosted relay / short-lived credentials while TURN is off (Android EN/ES hint, iOS TURN footer), and the older round's note that the non-hosted Android hint still calls the empty default a placeholder. Both reworded.

Verified: Worker vitest 123 passed, tsc --noEmit clean. No Rust changed. The Kotlin and Swift edits are not compiled locally; ios.yml runs at release.

CI on ce80d0f failed "the alarm revokes every due credential ... and
only due ones": runDurableObjectAlarm returned false. The test's seed()
armed the Durable Object alarm at the credential's due time, which the
tests set in the past. workerd fires a past-due alarm by itself, so it
could run (and clear) between seed() and the test's explicit
runDurableObjectAlarm, which then found no alarm. Locally the race was
lost every time (123 passed); on the CI runner it was won once.

seed() now arms at max(due, now + 60 s). runDurableObjectAlarm runs an
armed alarm immediately regardless of its time, so every test still
drives the alarm explicitly, and the automatic one can no longer fire
first. The first test's final assertion (next alarm = the later
credential's due time, an hour out) is unaffected: that key's time is
later than the 60 s floor.

No production code changed. Verified: vitest 123 passed, three runs.

Answers Antigravity's two newest #618 rounds (no blocking findings).

- turn.ts: handleTurn mints the credential upstream, then records its
  revocation in the budget object. If that call threw (a transient
  Durable Object or storage failure), the request ended in an unhandled
  500 with the admission still charged and a live credential nobody
  would ever revoke. It now fails closed: the credential is withheld,
  the admission refunded, and the client gets a 503 telling it to
  connect directly. Withholding rather than returning was chosen because
  the whole point of the record is that no handed-out credential escapes
  revocation; the minted one is used by no one and lapses at its TTL.
- budget.ts: one alarm could spend up to REVOKE_BATCH x REVOKE_TIMEOUT_MS
  (50 x 5 s = 250 s) on revocation requests against a hung upstream, and
  the object is single-threaded, so admissions would queue behind it.
  The loop now stops after a 15 s wall-clock budget; the keys it did not
  reach are still due, so the alarm's own re-arm (nextRevocation) fires
  again at once.
- to-dos/plans/v3.4.1-plan.md: rows 10b and 10c described the state of
  2026-10-18 (ladders "not waited for", bitstreams "compiling"). 10b now
  records the ladders as cancelled at the maintainer's word, 10c the
  2026-10-19 compiles and their margins. 10e ("after the oracle merges")
  is still true and is unchanged.

Not done, with reasons (replied on the PR):
- bolt job forwarding hosted_base: hosted_base is a workflow_call input
  only, and bolt runs only on workflow_dispatch, where it is always
  empty; bolt's output is never promoted to a release.
- Android validating relay URLs through a shared Rust parser: a UniFFI
  export plus both apps is a v3.4.2-sized change; the regex now refuses
  the empty-host and whitespace cases, and a malformed port still fails
  at connect.
- ra_glue.js reading RA_PROXY_BASE at import: browser RA is held off
  (D31); recorded for when it is enabled.

TURN stays off in production (TURN_ENABLED "false"), so neither Worker
change runs there until it is re-enabled. Verified: vitest 123 passed,
tsc --noEmit clean. No new test: the storage failure and the 15 s
budget both need fault injection or fake timers inside workerd, which
the suite does not have; stated rather than faked.

Review round 5: Antigravity's rounds at 22:30 and on 4949b3c

No blocking findings in either. Handled in d473889:

  • scheduleRevoke failure after the credential is minted. Valid. The handler now fails closed: the credential is withheld, the admission refunded, and the client gets a 503 (connect directly). Returning it would hand out the one kind of credential the record exists to prevent: one nobody will revoke.
  • One alarm can spend 50 x 5 s on a hung upstream. Valid. The revocation loop stops after 15 s of wall clock; the keys it did not reach are still due, so the alarm re-arms at once.
  • Plan rows 10b/10c stale. Fixed: ladders recorded as cancelled at the maintainer's word, the 2026-10-19 compiles with their margins. 10e ("after the oracle merges") is still accurate.

Not changed:

  • bolt does not forward hosted_base. hosted_base is a workflow_call input only, and bolt runs only under workflow_dispatch, where it is always empty. bolt's output is never promoted to a release.
  • Android validation through a shared Rust URL parser. A UniFFI export plus both apps is a v3.4.2-sized change. The regex refuses the empty host and whitespace now; a malformed port (:notaport) still fails at connect, with an error.
  • RA_PROXY_BASE read at import, rcheevosBase() lazily. Browser RA is held off (D31). Recorded for when it is enabled.
  • release_anchor_audit matching exact JSON layout. Intentional: npm writes both files in exactly this layout, and a layout change is something we want to see, not tolerate silently.

Neither Worker change runs in production while TURN is off. vitest 123 passed, tsc --noEmit clean.

Final round (d473889): non-blocking, carried forward

Antigravity reports no blocking issues. Its remaining suggestions are recorded for v3.4.2 rather than another round on the release PR:

  • sanitizeIceServers accepting an empty-string username / credential: TURN is off in production; to tighten when it is re-enabled (T-HOSTED-TURN-EXPIRY).
  • A retry key landing before the current one if the wall clock stepped backwards: the worst case is an immediate retry, not a lost revocation.
  • Android RELAY_URL and malformed ports / IPv6 literals: as before, the shared Rust validator is the fix, slotted for v3.4.2.
  • "Last Updated" dates beside the bumped headers, and bolt (answered in round 5).

Merging on green.

The v3.4.1 merge (5b82dab) failed main's `test (windows-latest)`, and
with it the `CI success` aggregate, so Auto Release skipped the tag:

    the_hosted_worker_names_the_workspace_version ... FAILED
    package.json root is not 3.4.1  (left: 0, right: 1)

The test matches `"name": "rustynes-hosted",\n  "version": "<v>"` in
services/hosted/package.json and package-lock.json, a pattern that spans
a line break. Windows CI checks the tree out with CRLF, so the literal
`\n` never matched there; every Linux run, local and PR CI, passed. The
PR's CI did not run the Windows test job, which is why #618 was green.

Correction: Antigravity flagged exactly this coupling to the files'
layout on #618, and the round-5 reply rejected it as intentional. The
layout part of that reply stands (npm writes this layout, and the point
of the test is the exact root entry, not any `version` key), but the
line-ending part was wrong. Both files are now normalised (CRLF -> LF)
before matching, rather than parsed as JSON.

Verified: the test passes with package.json converted to CRLF on disk
(the Windows condition), and on the LF tree; the file was restored
byte for byte afterwards.

…te (#622)

* fix(release): correct v3.4.1's desktop and PGO claims; fix the PGO gate

Two claims in the v3.4.1 release were wrong, found by checking the
shipped Linux download after Auto Release published it.

1. "The desktop binaries ... are compiled with [the hosted] address, so
   a room code works with no setup." The release builds do set
   RUSTYNES_HOSTED_BASE, but native desktop netplay never reads it: the
   hosted base is consumed only by the browser lobby (wasm_lobby.rs, wasm
   only) and the mobile bridge. rustynes_netplay::hosted::BUILD_HOSTED_BASE
   is an option_env! literal, and in the native frontend only `.is_none()`
   is evaluated, so the optimizer folds it and drops the string. Measured:
   the v3.4.1 x86_64-linux binary contains 0 occurrences of the URL (and 0
   of "workers.dev"). Desktop netplay connects directly by address, as it
   always has. Corrected in the release notes, CHANGELOG and every
   release anchor ("the browser and mobile builds pointing at it"), each
   correction marked in place with its date.

2. "Ships the profile-guided Linux binary that was actually optimized."
   The v3.4.1 PGO gate did not promote (speedup -5.05% against the 3%
   bar; run 39349205257), so the Linux download is the plain build.

The PGO gate itself was broken by the same misunderstanding. v3.4.1
(f6cb343) refused promotion unless the kept binary contained the hosted
base, meant as proof that the kept file is the `full` build rather than
Stage 4's test build at the same path. Since a native binary never
contains the base, that check could never pass: PGO promotion was
blocked permanently, hidden this time only because the speedup missed
anyway ("hosted base present=0" in the run). The marker is now the
RetroAchievements User-Agent ("RustyNES/<v> (<os>) rcheevos/<v>"),
compiled in only with the `full` features' retroachievements; the
shipped v3.4.1 binary contains it, and the v2.9.6 PGO binary (a test
build) is recorded as lacking it. release_anchor_audit's needle follows.
The unused HOSTED_BASE env on the gate step is removed; the optimized
build still exports RUSTYNES_HOSTED_BASE, harmless and future-proof.

Also:
- docs/agents/ci-and-release.md: a release PR from a feat/ branch runs
  CI's LIGHT matrix (Linux only), which is how a CRLF failure reached
  main and held the tag until #621; open release PRs from release/*.
- Tickets for the review suggestions deferred from #618 and #67:
  T-MOBILE-RELAY-VALIDATE, T-HOSTED-TURN-SANITIZE, T-WEB-RA-PROXY-LAZY
  (ROADMAP), T-MISTER-RTL-MUTANT-RUNS (to-dos/mister/TASKS.md).

The live v3.4.1 GitHub release body is updated to match this file.
Verified: release_anchor_audit 18, release_state_prose_audit 4,
release_notes_render_audit 9 passed; markdownlint clean.

* docs: align the hosted-base comments with what the desktop binary uses

Answers #622's reviews (no blocking findings).

- Antigravity: pgo.yml, release.yml and the anchor audit's doc comment
  still said the PGO archive needed the hosted base, contradicting the
  gate comment beside them. Reworded: the plumbing stays so the
  optimized build is configured exactly like the plain one, the base
  matters to the browser and mobile builds, and native desktop netplay
  does not read it. Kept rather than removed: dropping it would make
  release.yml's builds differ from the other shipped workflows for no
  gain, and the audit that keeps the literals in step still holds.
- CodeRabbit (CHANGELOG, notes line 7): lead with the behaviour (desktop
  netplay connects directly) rather than the binary's contents; the
  measurement (no copy of the address in the v3.4.1 Linux download) is
  kept as evidence, not as the claim.
- CodeRabbit (ci-and-release.md): Windows runs only in the full matrix
  (release/* PRs, pushes to main), so the guidance says that.
- CodeRabbit (TASKS.md): T-MISTER-RTL-MUTANT-RUNS fails closed on patch,
  build and gate-execution errors too, with BUILD-FAILED reported apart.

Verified: release_anchor_audit 18 and release_notes_render_audit passed;
markdownlint and actionlint clean.

* docs(tasks): one named result per mutant in T-MISTER-RTL-MUTANT-RUNS

CodeRabbit on #622: an aggregate exit status could hide which mutant
survived. The gate now prints exactly one result per row, naming the
mutant (CAUGHT, NOT CAUGHT or BUILD-FAILED).

…N-SANITIZE)

sanitizeIceServers accepted a `turn:` / `turns:` entry whenever its
`username` and `credential` were both of type string, and the empty string
is a string. Such an entry was returned to the client as a usable relay
credential, and every client would have failed only at Allocate time
(Antigravity on #618, v3.4.1). It also returned a STUN-only list as a 200,
which spends a credential admission on an answer that gives a client
nothing its own STUN default does not.

Now:

- a TURN entry whose username or credential is missing, not a string, or
  empty is dropped (as a credential-less TURN entry already was);
- the function returns `undefined` unless at least one TURN URL survives,
  so handleTurn's existing path refunds the admission (refundTurn) and
  answers 502 `turn-upstream`, which every client maps to "STUN only".
  No new code path in handleTurn: the refund and the 502 are the ones a
  network error already takes.

Gate (services/hosted, vitest):

- five new `... is a 502 and does not spend the budget` cases through the
  real router: empty username and empty credential on `turn:` and on
  `turns:`, and a STUN-only answer. Each asserts the 502, the
  `turn-upstream` code, an unchanged `minted` count (the refund) and, new
  for all eleven cases, that no `revoke:` entry was scheduled;
- a unit case refusing every (empty, non-empty) combination for both
  schemes, and keeping a good entry beside a dropped one;
- a unit case that a STUN-only list is nothing usable. The existing
  single-string-urls case now carries a TURN entry.

Red first: the 7 new tests failed against the old code (7 failed / 28
passed in turn.test.ts). After: turn.test.ts 35/35; whole suite 130/130
(123 before + 7); `tsc --noEmit` clean.

Mutations (each a value change, each restored and diffed):

- allow an empty username: 3 tests fail (both schemes' 502 + unit);
- allow an empty credential: 3 fail;
- accept a STUN-only list again: 6 fail;
- remove the refundTurn before the 502: all 11 `... is a 502` fail.

All caught. Not done: nothing here re-enables TURN (it stays off in
production, T-HOSTED-TURN-EXPIRY, which needs the maintainer's
credentials); nothing was deployed. A whitespace-only username is still
accepted; only the empty string is refused, as the ticket states.

Noted, not mine: on the first full run `lobby.test.ts` "closes a socket
that floods messages" timed out at load average 31 (nine agents on the
host); it passes alone (13/13) and in the later full run.

…PROXY-LAZY)

ra_glue.js exported `RA_PROXY_BASE = resolveProxyBase()`, a module-level
constant evaluated once when the module graph is instantiated, while the
rcheevos module location (rcheevosBase()) is read at loadModule(). A page
that set `<meta name="rustynes-ra-proxy-base">` or
`globalThis.RUSTYNES_RA_PROXY_BASE` after the glue was imported therefore
got a working rcheevos module and a proxy that failed closed on every call
(Antigravity on #618, v3.4.1).

Now `_proxyBase` is module state, "" until ra_init() resolves it. ra_init()
resolves it FIRST, before the module load can fail, because the Rust
bridge (wasm_cheevos.rs BrowserRaSession::init) reads ra_proxy_configured()
right after ra_init() whatever it returned. It is resolved only when no
session is live (`_client === 0`): a mid-session change would send one
session's calls to two proxies. ra_shutdown() already zeroes `_client`, so
the next ra_init() reads the page again. The server-call trampoline and
ra_proxy_configured() read `_proxyBase`; `raProxyBase()` replaces the
exported constant for the test. No Rust change: the bridge imports only the
functions, never the constant.

Gate (services/hosted/test/ra-glue.test.ts, vitest in workerd):

- "honours a base set after the module was imported": base set after the
  import, not visible before ra_init(), visible after it (ra_init itself
  returns false: the runtime has no rcheevos.wasm);
- "re-resolves after a shutdown, and refuses a bad base set late";
- the repository default case now also asserts ra_init leaves it "".

Red first: 3 failed (raProxyBase missing). After: ra-glue 9/9, hosted suite
132/132, tsc clean, `node --check` on the glue clean.

Mutations (values, each restored and diffed):

- M1 resolve at import again (the v3.4.2 behaviour): 2 fail. CAUGHT.
- M2 resolve after the module load instead of before: 2 fail. CAUGHT.
- M3 ra_proxy_configured re-reads the page instead of the session base:
  1 fails. CAUGHT.
- M4 drop the live-session guard (always re-resolve): 9/9 pass. NOT
  CAUGHT, stimulus blind: the Workers runtime cannot load rcheevos.wasm, so
  a live session (`_client != 0`) never exists in the test. Recorded in
  docs/cheevos-browser.md as the one rule the test does not pin; only a
  real-browser run with the Emscripten module can exercise it.

Browser RA stays held (D31); nothing was built with `browser-cheevos` or
deployed. Docs: web/cheevos/README.md step 4, docs/cheevos-browser.md
("Where the proxy base comes from"), CHANGELOG [Unreleased] Fixed. ADR 0015's
mention of RA_PROXY_BASE is left as written (an ADR is not rewritten).

…-MOBILE-RELAY-VALIDATE)

Android checked a custom signaling URL with a regex, iOS with
`URL(string:)` plus a host test, and the connect path parsed it a third
way (tungstenite's client request builder over the `http` URI grammar).
The three disagreed (Antigravity on #618, v3.4.1).

Probing the connect parser found a worse defect than the ticket's: for
`wss://h:notaport`, `wss://h:9000x`, `wss://h:99999`, `wss://h:65536`,
`wss://h:` and `wss://[::1]x`, `http::Uri::port()` returns None ("no
port"), and connect_bounded then used `port_u16().unwrap_or(443/80)`. So
those URLs were neither refused nor honoured: the client dialled the
scheme's default port on the named host. Android's regex accepted all of
them, plus an unclosed IPv6 literal and an upper-case `WSS://` that the
connect refuses.

Now:

- rustynes-netplay signaling_client: `parse_signaling_url(url) ->
  Result<SignalingTarget{host, port, tls}, String>` and
  `validate_signaling_url(url)`, ONE parser, which connect_bounded now
  calls (it no longer derives host/port itself). On top of the http
  grammar it refuses an empty host and reads the port text from the
  authority itself (after the last '@'; after `]` for an IPv6 literal):
  ASCII digits naming 1..=65535, else refused; junk after `]` refused.
  Not judged, documented: DNS validity of the host, scheme case (the
  grammar refuses upper case, so now everyone does).
- rustynes-mobile: `#[uniffi::export] np_validate_relay_url(url) -> bool`
  over that function. Generated bindings checked here with the crate's
  uniffi-bindgen: Kotlin `npValidateRelayUrl(url: String): Boolean`,
  Swift `npValidateRelayUrl(url: String) -> Bool`.
- Android Netplay.kt onlineNetplayConfigured: `return
  npValidateRelayUrl(url)`; the RELAY_URL regex is deleted.
- iOS NetplayModel.swift signalingConfigured: `return
  npValidateRelayUrl(url: u)`; the URL(string:) host test is deleted.
  Both still trim first and still send an empty URL to npHostedAvailable.

Gate: one table, crates/rustynes-netplay/testdata/relay_urls.tsv, 40 rows
(13 accept, 27 refuse; each with its reason):

- netplay: `the_relay_url_table_matches_the_parser` (every row through
  validate_signaling_url; asserts >=10 accept and >=20 refuse rows so an
  emptied table cannot pass); `the_parser_reports_the_port_and_host...`;
  `connect_refuses_a_bad_port_without_dialling` (SignalingClient::connect
  on ws://127.0.0.1:notaport closes with "invalid port" instead of dialling
  port 80).
- mobile: `the_exported_relay_validator_matches_the_shared_table` (the
  same rows through np_validate_relay_url) and
  `the_shells_ask_the_bridge_and_parse_nothing_themselves`, a SOURCE check
  of Netplay.kt and NetplayModel.swift (each gate returns the bridge's
  verdict, contains no Regex/.matches/URL(string, and RELAY_URL is gone).

Mutations (values; each restored and cmp-checked):
N1 ignore the port text: 3 netplay tests fail. N2 allow port 0: 1 fails.
N3 allow an empty host: 1 fails. N4 allow a signed port (+80): 1 fails.
N5 allow junk after `]`: 1 fails. N6 export returns !url.is_empty(): the
mobile table test fails. N7 Android back to a regex: the source check
fails. N8 iOS back to URL(string:): the source check fails. All caught.
A `len <= 5` clause on the port digits was removed rather than left
unpinned (u16 parsing already bounds the value).

Gates: cargo fmt --all --check clean; clippy -D warnings clean for
rustynes-netplay (default and netplay-client, all targets) and
rustynes-mobile (all targets); rustdoc -D warnings clean for both;
rustynes-netplay --features netplay-client 190 passed / 0 failed / 3
ignored; rustynes-mobile 68 / 0 / 0.

NOT VERIFIED HERE, stated plainly: the Kotlin and Swift edits were not
compiled (no kotlinc, no swiftc, no Android SDK or Xcode on this host).
The function names and signatures they call were checked against
bindings generated from this build, and the source check pins the call
sites, but the first compile of each app is the coordinator's/CI's.

Docs: docs/netplay-webrtc.md (Clients, Android / iOS), CHANGELOG
[Unreleased] Fixed.
