fix(release): correct v3.4.1's desktop and PGO claims; fix the PGO gate - #622
Conversation
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.

Explanation
PASS — The reviewed range changes release documentation, CI workflow gating, and an audit test. No emulator, frontend, netplay runtime, or other user-visible behavior code changes are present. The release workflow change is comment-only, and the PGO change is CI/tooling logic.
CHANGELOG.mdupdates the existing[3.4.1]entry, while[Unreleased]remains empty; no new Unreleased entry is required for this CI/tooling-only correction.

-
Explanation
PASS: The authoritative PR diff adds no new
.unwrap(),.expect(), orpanic!()calls. The only Rust change is incrates/rustynes-test-harness/tests/release_anchor_audit.rs, within a#[test]audit, and it changes comments plus a string-matching needle. Existing target calls in that file are unchanged. No runtime code changes apply these operations to untrusted input.

Explanation
PASS: The reviewed range changes only release documentation, workflow YAML, and an audit test. The authoritative diff contains no added

Automated first-pass review by |
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.
