## Summary
- remove the GitHub-hosted desktop smoke job from the desktop release
workflow
- remove the smoke result from manifest assembly dependencies and
promotion conditions
- retain the local smoke tooling for future repair and targeted
validation
The first release execution of this gate spent its full 10-minute
Playwright timeout traversing the 10,000-row fixture, then produced a
987 MB diagnostics upload. All signed platform builds succeeded, but the
smoke prevented manifest publication. This restores the previously
established release boundary while the harness is made suitable for CI
separately.
### Testing
- parsed `.github/workflows/release.yml` with Ruby Psych and asserted
the smoke job/dependencies are absent
- `scripts/test-release-ref-contract.sh`
- exact pushed commit passed the repository pre-push hook

## Summary
- replace the nested one-line shell quoting used to read the Playwright
package version
- write the resolved version to `GITHUB_OUTPUT` from a multiline shell
step
## Why
The `desktop-v0.5.12` release smoke job failed before executing tests
because Bash received escaped quotes inside command substitution and
parsed the Node expression as shell syntax.
## Validation
- `bash scripts/test-release-ref-contract.sh`
- isolated execution of the new shell fragment with a fixture
`@playwright/test/package.json`, producing `version=1.58.2`
- `git diff --check`

## Summary
- add `just desktop-release-smoke`, a deterministic desktop
correctness/reachability smoke against an ephemeral real local relay
- preserve existing DM history when the first live DM enters a pageless
query window, the desktop-v0.5.10 disappearing-DM regression
- enforce foreground JS ordering: a frame and actionable sidebar input
must dispatch before mounted stale queries begin resume refetches, while
separately requiring the navigation to commit promptly
- seed a 10,000-event dense-second fixture and verify exact event-ID
reachability, SHA-256 identity, ordering, duplicate absence, bounded
mounted rows, and drained render work
- isolate Postgres per run, serialize the shared Redis DB, retain
phase/relay/Playwright diagnostics, and gate desktop release manifest
assembly on the smoke
This is deliberately **not a performance-regression gate**. CDP and
action timing fields are informational only. There is no
candidate/baseline comparison or threshold. A future performance lane
needs repeated equivalent fixtures, discrete interaction samples, and an
explicit comparator/noise policy.
The diagnostics record the fixture version, row count, wall-clock base
timestamp (`fixtureSecond`), expected event-ID hash, observed state, and
measurements. Because the created-at floor requires a current timestamp,
paired comparison remains disabled.
The release job runs on an isolated GitHub-hosted runner. The script
also guards automatic local runs with a Redis allocation lock. Its
remaining direct-PID cleanup and free-port selection race mean it should
not be repurposed onto a persistent concurrent shared runner without
first hardening process-group cleanup and port reservation.
### Related issue
N/A
### Testing
- `pnpm --dir desktop typecheck`
- focused real-local-relay release smoke passed after adversarial review
fixes
- identical DM witness passed current and failed `desktop-v0.5.10` with
the history-loss signature
- identical foreground witness bytes
(`2c1e97df04c9b8ca0304b66bbbe9bdb4d08924ad8ce0f68a9c490458fcc3aca8`)
failed `desktop-v0.5.10` structurally: the first resume fetch was marker
1, before first frame/sidebar dispatch at marker 8
- with PR #5696 (`59f613c40`) merged, the witness showed focus at 951.3
ms, first frame at 951.6 ms, click dispatch at 952.1 ms, first resume
fetch at 968.9 ms, and route commit at 992.4 ms
- the gate therefore protects first paint and actionable input dispatch;
route commit is a bounded responsiveness witness, not a prerequisite for
resume work
- the corrected focused foreground scenario passed at
`6d9b5be40da58bbee92a856b04c3558946d0a950`; the prior merged-tree full
run passed DM retention and 10k reachability before exposing this
contract mismatch
- pre-push passed on exact pushed head
`6d9b5be40da58bbee92a856b04c3558946d0a950`, including desktop checks,
typecheck, desktop tests, Rust tests, mobile tests, and Tauri checks
- full 10,000-event scenario reached 10,000/10,000 exact IDs with
matching SHA-256, 199 continuation requests, and 95 mounted rows in
about 4.4 minutes
- reduced-row review run passed in 18.4 seconds
### Foreground witness boundary
The Chromium test is a deterministic JS policy gate. Headless Chromium
does not expose an honest blur/focus transition in this fixture, so the
test drives the production focus listener and `document.hasFocus()`
predicate together and records that simulation explicitly. It proves
refetch fan-out ordering, not AppKit activation, WKWebView paint, or an
activating physical click. A packaged macOS native lane is still
required before claiming the actual desktop activation experience is
certified.

## Summary
Separate OSS desktop artifact publication from fleet-wide auto-update
promotion.
- retain the exact generated updater manifest as `updater-manifest.json`
on each immutable `desktop-vX.Y.Z` release
- stop the tag-triggered build from mutating
`buzz-desktop-latest/latest.json`
- add a `main`-only manual promotion workflow with one global
concurrency group
- validate stable semver, release/tag commit identity, draft/prerelease
state, exact platform set, signatures, version-bound asset URLs, asset
existence, monotonicity, idempotent retries, and a final stale-state
check before writing
- document the operator flow and pin the split with focused contract
tests
## Safety behavior
Publishing a versioned GitHub release no longer exposes it through the
in-app updater. Operators can install and test those exact
signed/notarized artifacts, then manually run **Promote OSS Desktop
Auto-Update** with the stable version.
Promotion rejects downgrades. A same-version retry succeeds only when
the rolling and candidate manifests are byte-identical. The workflow
re-reads the current rolling version immediately before its only write
and records the actor, source tag commit, previous version, manifest
digest, and run URL.
## Verification
Verified at commit `39caf1603be06bb476905225ec55f7bbbe86b237`:
```text
scripts/test-oss-desktop-promotion.sh
OSS desktop promotion contract passed
scripts/test-release-ref-contract.sh
release ref contract passed
git diff --check origin/main...HEAD
(clean)
```
The repository pre-push hook also passed `branch-skew` for the exact
pushed head; package suites were correctly skipped because this change
only touches release workflows, scripts, and documentation.

## Summary
Official Linux desktop packages (`.deb` / AppImage) are built without
`--features mesh-llm`, so they ship the `mesh_llm_stubs` backend and
Settings → Compute always fails with `mesh-llm feature not enabled`.
This PR adds the feature flag to the two Linux build commands:
- `release.yml` → `release-linux` job
- `linux-canary.yml` → canary build
That's the whole diff — 2 lines. Fixes#3788 (Linux); see also #3841
(dup with UI-gating PR #3914) and the Windows twin #2836/#3223.
## Why no native prebuild step (unlike the macOS job)
The macOS job carries Metal llama prebuild/cache steps from #798. Linux
doesn't need an equivalent:
- `mesh-llm-host-runtime` is compiled with `dynamic-native-runtime` and
installs the recommended runtime on first use (verified by sha256
checksum over HTTPS; upstream's signature verification path is not yet
implemented — default policy is `RequireChecksum`, per
`mesh-llm-runtime-install/src/lib.rs`)
(`desktop/src-tauri/src/mesh_llm/mod.rs` —
`initialize_mesh_native_runtime`), so release builds work on clean
machines without bundling llama.cpp.
- Upstream publishes Linux x86_64/aarch64 runtime bundles for the pinned
`v0.74.0` line, and `scripts/ensure-mesh-native-runtime.sh` already maps
`meshllm-native-runtime-linux-x86_64-cpu` / `linux-aarch64-cpu` for
local/e2e use.
- The unmerged branch `micn/mesh-node-download` (`96f29417a`) treats
even the macOS prebuild steps as removable dead weight for the same
reason.
## Background
The omission is historical drift, not a decision: Linux packaging
predates the mesh feature flag (#693), mesh became opt-in for
build-cost/reliability reasons (#823, #1183), and #1221 re-enabled it
for releases by editing only the macOS build line. `release-linux` and
the later `linux-canary` copy were never revisited.
The mesh shutdown hard-exit/relaunch path is gated `all(mesh-llm,
target_os = "macos")` because ggml/Metal destructors abort on macOS;
ordinary mesh shutdown (`shutdown_mesh_runtime`) is cross-platform, so
Linux falls through to the generic path.
## Validation
- [x] `./bin/cargo check --manifest-path desktop/src-tauri/Cargo.toml
--features mesh-llm` green at base `2c0ac2467` (feature graph compiles
at the pinned v0.74.0 line)
- [ ] Linux canary run with this change: AppImage/.deb build succeeds
and binary contains real `mesh_llm` symbols (not `mesh_llm_stubs`)
- [ ] Installed package: cold-start → Settings → Compute → runtime
download → serve → clean shutdown
The last two need a Linux run/host. **Note (from review):**
`linux-canary.yml` is `workflow_dispatch`-only and its `Require main`
step rejects non-main refs, so the canary cannot run on this branch
pre-merge — and `.github/workflows/**` matches no ci.yml paths-filter,
so this PR's own CI does not exercise the changed lines. Validation
sequencing is therefore merge → dispatch linux-canary on main →
live-package pass, with a trivial 2-line revert as the escape hatch.

# Kubernetes backend plugin (crates/buzz-backend-kubernetes) + desktop
deploy path
Implements docs/remote-agents.md (merged @ 28ae6cd21) as ONE PR: the
provider
binary, the desktop changes that make it work, the harness inactivity
reaper,
the Sprig image, and the conformance/live-test suites.
Channel: buzz-remote-agents (29414326-dba7-402d-b384-b1b34d63a2e6),
thread c42b70ef.
## What's here (by lane)
- **crates/buzz-backend-kubernetes** (Dawn): stdin/stdout JSON provider,
info +
deploy; pure classify.rs (one match arm per spec state-machine row);
reconcile/GC with ownership-marker gate + same-clock orphan check;
per-attempt
immutable Secrets; three-tier env with clear-then-write authoritative
tier.
- **Desktop** (Mari): KD3 launch block from resolved descriptor, KD5
pre-secret
negotiation gate (resolve-once → stage-and-digest → info → protocol gate
→
deploy), KD1 Windows extension strip, bundling (externalBin + Justfile +
release/canary workflows + stub loops), tauri.windows.conf.json platform
override (Decision B: no Windows artifact).
- **buzz-acp** (Max): KD4 BUZZ_ACP_EXIT_AFTER_INACTIVITY reaper
(pool-independent;
reset only at accepted dispatch; in-flight turn/heartbeat defers, never
resets);
BUZZ_ACP_EXIT_AFTER_INACTIVITY + BUZZ_ACP_NO_PRESENCE reserved. KD8 fix.
- **Image + tests** (Perci): Dockerfile.sprig (digest-pinned bases, exec
buzz-acp
PID 1, relay-scoped credential config), image contract script, provider
conformance suites (golden wire fixtures shared with desktop tests),
live-local
runbook (namespace-scoped, shared-cluster safe).
- **Docs** (Sami, first commit): citation re-pin c1bca1b56 → 28ae6cd21
(44/49
were already byte-exact; 3 offsets fixed) + I3 presence-bound correction
(below).
## Named spec deviations (deliberate, each with rationale)
1. **No baked default image yet.** ghcr.io/block/buzz-sprig is
unpublished
(verified: anonymous pull 403 vs control 200). Omitted `image` returns
an
in-band field-required error instead of a default.
2. **Image override STRICTER than spec §Image:** digest-only
(`name@sha256:<64hex>`); ALL tags rejected; `name:tag@digest`
normalized.
With no baked default the override is the only path, so tag-acceptance
would
make mutability the v1 norm. Strictness is reversible; a moved tag under
an
nsec is not. Baked digest default + tag re-acceptance = follow-up with
image
publish.
3. **imagePullSecrets not in schema (v1).** Explicit user images may
rely on
namespace-preprovisioned pull credentials — the substrate boundary.
Field
added only if the publish decision proves it necessary. 9-field budget
intact.
4. **Decision A closed: writable empty workspace.** Nest projection =
named
follow-up; no image-side scaffolding.
5. **Decision D overridden by Tyler (event b55398d8):** provider ships
bundled
with the desktop like buzz-acp/buzz-agent; spec §Distribution's separate
release workflow deleted for v1.
6. **I3/vision presence bound corrected 90s → 180s.** PRESENCE_TTL_SECS
moved in
#3783 during this spec's base→merge window; the number was inherited,
not
chosen. Spec :206/:216/:928 + inline quote + VISION_REMOTE_AGENTS.md:59
corrected. ← Tyler: the vision is your document; this edit is flagged
for
your explicit eyes.
7. **Spec citations are pinned to 28ae6cd21** (main at spec merge) and
resolve
there, not at this PR's head — this PR's own lanes move
crates/buzz-acp/src/lib.rs by ~100 lines (19 citations across
KD4/KD6/KD7/
§Stop/§Launch data). Known Defects rows fixed BY this PR retire on
merge;
the section documents main as of the pin.
8. **KD7 grace tension declared:** pod terminationGracePeriodSeconds=60
vs
KD7's measured ~87s shutdown tail at parallelism 10 (~197s at cap 32).
KD7 is ruled out of scope, so L1-3's "enough grace for full graceful
shutdown" is NOT met at default config — deliberate, resolved by the KD7
follow-up, not silently.
## Question for Tyler
Will ghcr.io/block/buzz-sprig publish PUBLIC? If private-by-policy,
§Image needs
an imagePullSecrets story before the baked-default follow-up can land.
## Out of scope (named follow-ups)
KD6 exit-code contract + KD7 shutdown budget (gate OnFailure), OnFailure
restart
policy, Windows provider binary, PVCs/nest projection, mesh
deployability,
sprig image publish workflow + baked multi-arch digest default.
## Reproduce locally (four traps that cost us real time)
**1. Git hooks inherit the invoking shell's PATH — pin the shell, not
just your
verification commands.** `rust-toolchain.toml` pins `1.95.0`, but the
rustup shim
that honors that pin lives in `~/.cargo/bin`. If Homebrew's cargo is
earlier on
PATH, `cargo` in this repo is 1.89.0, which cannot build the workspace
at all:
```
$ /opt/homebrew/bin/cargo check -p buzz-db
error: rustc 1.89.0 is not supported by the following packages:
sqlx@0.9.0 requires rustc 1.94.0
... # exit 101
```
Verifying with `PATH="$HOME/.cargo/bin:$PATH" cargo test` does *not*
protect the
push: lefthook's `pre-push` → `just test-unit` re-resolves `cargo` from
the
shell's own PATH, so a green local run is followed by a hook failure on
a crate
you never touched. Export the PATH for the whole shell, not per-command.
This
bit twice.
**2. Line-scope your mutations, or the mutation edits its own
detector.** When
mutation-testing the respond-to guard, a whole-file `sed` on the mode
literal
touches 5 sites — the guard *and* the fixtures/assertions that test it.
The
mutation and its detector move together and the suite stays green, which
reads
as "this code is dead" when it actually means "you deleted the
experiment":
```
# WRONG — 5 sites, guard and tests mutate together
$ sed -i '' 's/"allowlist"/"allowlist-DISABLED"/g' src/env.rs
test result: ok. 145 passed; 0 failed # false survivor
# RIGHT — 1 site, anchored to the guard's own definition line
$ sed -i '' '/^const RESPOND_TO_ALLOWLIST/s/"allowlist"/"allowlist-DISABLED"/' src/env.rs
failures:
env::tests::allowlist_mode_with_an_empty_list_is_refused
env::tests::an_allowlist_entry_that_is_not_64_hex_is_refused
test result: FAILED. 143 passed; 2 failed # real kill
```
Restore by copying a pristine file back and confirming `git diff --stat`
is
empty, not by re-running an inverse `sed`.
**3. A completeness guard is not a correctness guard.** The shared wire
fixture
`tests/fixtures/provider-wire/deploy-full-launch.request.json` passed
every test
we had while containing four classes of invented data (wrong
`respond_to`
encoding, an env key no emitter writes, allowlist entries that fail the
harness's own 64-hex rule, a `launch.env` key from no descriptor layer).
The
provider's tests could not have caught this: its types are deliberately
indifferent to these values (`Option<String>`, `Vec<String>`, arbitrary
map), so
"the provider parses it" was never evidence that the desktop emits it.
The fix
was not a stronger provider assertion but a rule about provenance —
"recorded"
means executed-and-transcribed, and the desktop's whole-object equality
test is
the only enforcement that can exist. See the fixture README.
**4. Every drift this arc was a value that agreed with itself.** Five
invented
values were found, and not one was caught by an assertion failing — each
was
caught by someone asking where a value came from. A named constant
referenced
symbolically on both the fixture and assertion side. A `sed` that
mutated its
own detector. Six probe rows that all died at the same unrelated error.
A
descriptor struct literal compared against a fixture built from that
literal
(`launch.args: ["run","--session"]`, which the resolver actually returns
as
`["acp"]`). The general defense is not more assertions but provenance: a
stub is
a control that varies nothing, and the more faithful it looks the better
it
hides. Ask what executed, not what passed.
*Fixture-test determinism caveat (post-verification, Quinn + Dawn).* The
desktop's whole-object fixture test calls the real resolver, which
consults a
process-global harness registry whose own docs require
`registry_test_lock`
for any test touching it. The fixture test holds no lock and is
nonetheless
deterministic — but by containment, not by ordering. Measured, not
derived:
planting a definition with `id: "goose"` directly into the registry
(bypassing
the loader) changes the resolved descriptor from `args: ["acp"]` to
`args: ["--poisoned"]`, so `resolve_effective_harness_descriptor`
**does**
reach the registry for this id — it does not short-circuit on the
builtin
table first. Two controls discriminate: an empty registry and a registry
poisoned under a *different* id both return `["acp"]`. What actually
protects
the test is that the registry has exactly one writer
(`update_loaded_harness_registry`, reached only via
`warm_harness_registry_from_dir`) — but that writer concatenates **two**
sources of unequal strength (`custom_harnesses.rs:319-326`). Custom
files
pass through `load_custom_harnesses`, whose `check_id_collision` rejects
the
reserved builtin id `goose` case-insensitively at the loader — and that
leg
is tested (`load_applies_id_collision_check` writes a real `goose.json`
and
asserts the loader drops it). Preset definitions
(`preset_harness_definitions`, `presets.rs:177-193`) are a bare `.map`
over
`PRESET_HARNESSES` with **no collision check** — exhaustive call-site
enumeration at `60007fda4` finds four production `check_id_collision`
sites,
none on the preset path. That leg holds only because `goose` is not in
the
preset table today (intersection of TIER1 and preset ids is empty) —
executed, not just read: adding a preset with `id: "goose"`,
`args: ["--poisoned"]` and warming via the normal preset-only path
(`warm_harness_registry_from_dir(None)`, no custom dir, no direct
writer)
flips the fixture's emitted `launch.args` from `["acp"]` to
`["--poisoned"]`
at `60007fda4`, command/env/policy_env unchanged. So: no test in the
suite
can put a `goose` entry in the registry
via the custom path, and no preset currently carries one, so no
interleaving
can perturb this fixture — containment with one checked leg and one
coincidental one. A future fixture built on a **non-builtin** runtime id
has
no containment at all — it would be order-dependent against whatever
registry-writing test ran last and must take the lock.
*Late instance, found while reviewing the mode guard.* The guard
exact-matches
`respond_to` untrimmed and case-sensitively, which is only correct if
clap's
`ValueEnum` derive is case-sensitive. `config.rs` gives two answers: the
derive
at `:448-453` carries no `ignore_case`, while the crate's own tests call
`RespondTo::from_str(s, true)` — `ignore_case = true`. Reading the
source
supports either. Measured on the built binary instead: `owner-only`
starts,
`OWNER-ONLY` / `Owner-Only` / `ALLOWLIST` / `NOBODY` all exit rc=2
`invalid
value`. Case-sensitive at the CLI, so the guard is right — and right for
a
reason the source does not state. The `from_str(_, true)` tests exercise
a
different surface and are not evidence about the CLI.
*Corollary, and the sharper half.* When a test helper **reimplements**
production instead of calling it, the helper is a fork — and a fork can
be
right while production is wrong, or wrong in the same way, and the suite
reports green either way. Both `BUZZ_ACP_ALLOWED_*` gates are forked
like this:
production compares **strings** while the helpers compare **post-parse
enums**
(`config.rs:2623`) or re-derive the split
(`buzz-cli/.../channels.rs:1296`).
Production and the helper each carry their *own* copy of the empty-entry
filter
(`:1025` and `:1300`), so fixing one says nothing about the other.
Measured on
`buzz-cli`, restoring byte-exact between runs:
| tree | result |
|---|---|
| baseline | 274 passed |
| drop the empty-filter in **production** only (the real fix) | **274
passed** — no signal |
| drop it in the **test helper** only | **273 passed, 1 failed**
(`channels.rs:1338`) |
Two independent defects, stacked, and worse together than either alone:
production can be fixed with no test ever noticing, *and* the helper
cannot be
corrected without a false alarm demanding the bug back. The root cause
is one
bit of type information — `check_allowed_channel_add_policy(allowed_raw:
&str,
..)` cannot represent "unset", while production reads `env::var(..) ->
Result`,
where unset and `""` are different states. A helper whose parameter type
can't
represent all of production's input states isn't testing production's
states —
it's testing a subset it silently chose. Same family as the
struct-literal
descriptor and the fixture drift: the test and the thing it tests
agreeing with
each other, rather than the test measuring the thing. Neither defect is
in this
PR's diff (`git diff --name-only 28ae6cd21 <head> -- crates/buzz-cli` is
empty); both are now filed as NIP-34 issues on this repo: the fail-open
+
fork-helper defect at issue event `0524a4113f2d97fd…` and the respond-to
self-lock at `e32837498969b5e7…` (filed 2026-08-02 after Quinn measured
that
no prior filing existed — zero hits on GitHub `block/buzz` open *or*
closed
and zero on the relay's kind:1621 issues, against working positive
controls). The prescription was itself
mutation-tested before being written down: repairing the fork's
signature
(`Option<&str>` + assertion → `None`) still let the reintroduced
production
bug ship 274-green — an expressive fork is still a fork; it never
executes
production. So the `buzz-cli` fix has **three parts and one explicit
keep**:
drop the production filter; **delete** the helper and point its tests at
the
real `cmd_set_add_policy` (which self-discriminates by error variant —
`Usage` = refused, `Network(BadScheme)` = passed the gate — no relay
needed);
serialize the env-var tests behind one
**`tokio::sync::Mutex::const_new`**
lock taken with `.lock().await`, including the pre-existing `:1362`
integration test (the fork was silently buying test isolation — without
the
lock, parallel runs flake nondeterministically; a `std::sync::Mutex`
held
across `.await` trips `clippy::await_holding_lock` under `-D warnings`);
and
**keep** the then-dead `!allowed.is_empty()` clause with a comment
saying
why. It is unreachable-false (`split(',')` never yields an empty vec),
but it
is the only thing that keeps the reintroduced production bug detectable
—
mutation-tested: on a tree that deletes the clause, reintroducing the
empty-filter bug survives 275/0, because `""`/`","`/`" "` refuse either
way
and the filter goes semantically inert. Dead code can be load-bearing
for
tests: "provably unreachable" is an argument about behavior, never about
coverage. When a helper forks production, the fix has to delete the
fork:
any change that leaves two implementations standing can only ever be
verified against the one the tests call. *Final shape:* the keep and the
broad lock are both artifacts of the fork surviving in some form. The
extraction variant (Dawn, mutation-tested at `60007fda4`) removes the
tension: extract one `check_channel_add_policy_allowed(Option<&str>,
&str)`
that **production calls**, with the `Option` placed at the env boundary
where the `Result<String, VarError>` bit actually lives. 5/6 mutants
killed; the empty-filter survivor is proven **equivalent** (exhaustive
6174-pair check, 0 divergences, with a diverging negative control;
independently re-derived by a second generator — different tokens and
shape — 0 divergences on admitted policies, 500 on a non-admitted
control),
not a coverage hole — on a one-implementation tree there is no fork left
to
witness, so no dead clause needs keeping. One scope line on that
equivalence: it is **caller-conditional**, a property of the only
current
caller, not of the gate function — `cmd_set_add_policy`'s own match at
`:1027-1034` admits only three policies before the gate runs; a second
caller reaching the gate with arbitrary strings resurrects m1 as a real
hole. The lock does not disappear, it
narrows (Dawn's own correction, caught by Mari): lock exactly the tests
that mutate the process env — three-plus-one on a fork tree, two on the
extraction tree — behind one `tokio::sync::Mutex`, and the lock is part
of
the assertion, not hygiene: with it deleted, the gate test fails 8/8
runs
deterministically by receiving `Network(BadScheme)` where it expects
`Usage` — the unset test's `remove_var` clobbers the other's `set_var`,
and
**the gate test passes straight through the gate**, a false negative on
the
exact authz assertion the test exists to make. State it as an outcome:
these two tests must not observe each other's env writes. 276/0 stable
across 5 parallel runs, clippy `-D warnings` clean; independently
verified
(patch applied to a second worktree: result blob `d67e584be` matches the
patch index, full mutant matrix reproduces row for row). One new row no
earlier
prescription covered: collapsing unset into `Some("")` fails **closed**
—
an unconfigured deployment refuses every policy — killed by the unset
test.
Patch: `OUTBOX/BUZZ_CLI_ADD_POLICY_GATE_EXTRACT_FIX.patch`. The filed
issue
(`0524a411…`) carries the fork-shape prescription; whoever picks it up
should prefer the extraction shape, drop the dead-clause keep with it,
and
keep part 3 outcome-shaped: serialize whichever tests mutate the env.
## Verification (final HEAD `60007fda4`)
- Full touched-package suites at each integration merge (log in plan
file).
At candidate parent `00e5b5fe9`: buzz-backend-kubernetes 154,
buzz-acp 673, desktop tauri 2100+3, pnpm 3908, workspace clippy/fmt/tsc
all clean. The only delta to `60007fda4` is one character in
`scripts/test-k8s-sprig-image-live.sh` (heredoc escape so the readlink
probe evaluates pod-side, not host-side at render); `crates/` tree hash
is byte-identical at both SHAs, so the Rust receipts attach by tree
identity. buzz-backend-kubernetes suite re-run in-shell at
`HEAD == 60007fda4`: 154 passed.
- Adversarial one-HEAD gate (Sami): guard matrix 12/12, predicate
mutants
7/7, doomed-invocation finding closed end-to-end; tree-hash carry to
`60007fda4` confirmed (crates/buzz-backend-kubernetes blob unchanged).
- Live-local pass per TESTING.md + skill-buzz-testing (Perci, at
`60007fda4`): explicit `docker-desktop` context, digest-qualified image
imported into node containerd `k8s.io` namespace, pull policy `Never`;
pod printed `DIGEST_ABI_OK`, `resolved_spec` and `image_id` both the
exact requested digest, script exit 0. Dedicated per-run namespace,
ownership labels on every object, scoped cleanup verified empty after.
- Implementation review (Wren) at `60007fda4`: 9.6 minimalness /
9.4 elegance / 9.3 correctness, no blocker.
- `origin/eva/k8s-backend` == `60007fda4` (ls-remote verified; SHA
identity is byte identity).

## Summary
- document `Prepare Desktop Release` as the canonical desktop release
entry point
- describe the frozen candidate, exact-head approval, and true
merge-commit contract
- document all platform outputs and complete release App/signing
configuration
- link the release runbook from the README
- allow stable reruns to repair the rolling updater manifest after the
versioned release has already published
## Release blocker
The live repository cannot currently complete this flow: repository
settings disable merge commits and the `main` ruleset allows only
squash, while `scripts/verify-desktop-release-merge.sh` requires a
two-parent merge whose second parent is the approved candidate. Those
settings must allow merge commits before a desktop release PR is merged.
## Validation
- `bash scripts/test-desktop-release-candidate.sh`
- `bash scripts/test-release-ref-contract.sh`
- `git diff --check`
- verified live repository merge settings, `main` ruleset, release tag
ruleset, Actions variable names, and secret names with GitHub API
- independent review by Princess Donut; incorporated all findings,
including the rolling-manifest retry gap and unsigned Windows labeling

## Summary
- add a manual desktop release preparer that regenerates one
version-only candidate from current `origin/main`
- validate deterministic complete changelog accounting, candidate
authorship, allowed files, exact-head approval, required checks, and
two-parent merge topology before tagging the reviewed candidate
- move desktop tags/releases from `v*` to `desktop-v*` while preserving
relay, chart, push-chart, and mobile behavior
- stage all four platform outputs in Actions artifacts and grant GitHub
release write access only to one final all-platform-gated publisher
- publish the versioned release only after complete artifact assembly;
update stable `latest.json` last; never promote prereleases or published
rebuild outputs
## Safety properties
- desktop tags point to the reviewed candidate SHA, not the merge commit
- release builds remain tag-bound and reverify tag == checked-out HEAD
- one final writer fails closed on artifact basename collisions
- per-tag concurrency serializes publication without cancellation
- published reruns do not replace immutable versioned assets or promote
signatures from a rebuild
- candidate branches use an explicit remote OID lease when regenerated
## Validation
- `scripts/test-desktop-release-candidate.sh`
- `scripts/test-release-ref-contract.sh`
- `scripts/test-mobile-release-contract.sh`
- changed workflow YAML parsing (Ruby Psych)
- changed shell syntax (`bash -n`)
- `git diff --check`
- push hooks: branch-skew, Rust workspace tests (1,853 passed), desktop
Tauri tests (3 passed)
## Coordinated companion
- squareup/buzz-releases#79 updates the manually entered desktop
source-tag contract to stable-only `desktop-v*`
- merge the private contract companion before the first namespaced
desktop release
## Rollout blockers (no settings changed here)
Before the first candidate/release:
1. enable merge commits in repository settings
2. allow `merge` in ruleset `13596885`
3. require approval after the last push in ruleset `13596885`
4. include `refs/tags/desktop-v*` explicitly in release ruleset
`14378754`
5. prove the non-publishing candidate/merge/tag/artifact validation path
before any production release
Do not test the old workflow with a prerelease: it can still mutate the
production rolling updater release.

## What and why
The Buzz AppImage is built on `ubuntu:22.04`, which links WebKitGTK
against FreeType 2.11.1. Because `libfreetype.so.6` is on the
linuxdeploy community excludelist, the bundled WebKit loads the
**host's** FreeType at runtime instead of the bundled one.
FreeType 2.13.0 (released 2023-02-09) added `FT_Bool read_variable` to
`FT_ColorStopIterator`, growing the struct from 16 to 20 bytes. Any host
running FreeType ≥ 2.13 (Fedora 42+, Ubuntu 24.04+) has a struct-layout
mismatch with the 22.04-compiled WebKit. The mismatched offsets corrupt
color-stop index arithmetic inside Skia's COLRv1 renderer, producing the
assertion abort in issues #2548 and #2982:
```
stl_vector.h:1123: Assertion '__n < this->size()' failed.
... colrv1_configure_skpaint(FT_Face, ...) ...
```
## Fix
Bump the build container to `ubuntu:24.04` (noble), which ships FreeType
**2.13.2**. Noble's struct layout matches every crash-affected host. The
ABI mismatch disappears and the crash is eliminated at root.
WebKitGTK also advances from **2.50.4** (jammy backport) to **2.52.3**
(noble backport).
## Glibc floor change
| Build base | glibc floor | Oldest supported AppImage distro |
|---|---|---|
| ubuntu:22.04 (before) | 2.35 | Ubuntu 22.04 LTS, Debian 12 |
| ubuntu:24.04 (after) | 2.39 | Ubuntu 24.04 LTS, Fedora 40+ |
Ubuntu 22.04 LTS and Debian 12 users lose AppImage support. Both
distributions continue to receive first-class `.deb` / `.rpm` packages,
which use the system WebKit and are unaffected. The crash-affected users
(Fedora 42/44, Ubuntu 24.04+) all have glibc ≥ 2.39.
## Changes
- `.github/workflows/linux-canary.yml:24` — container pin updated to
`ubuntu:24.04@sha256:4fbb8e6a…`
- `.github/workflows/release.yml:479` — same container pin updated
- `.github/workflows/release.yml:501` — comment version string updated
from 22.04 to 24.04
`fix-appimage.sh` and `desktop/src-tauri/**` are untouched. The #3573
fontconfig stopgap remains active; retirement is a separate follow-on PR
once this fix is verified on a shipped build.
## Sequencing
`docs/linux-rendering-troubleshooting.md` (introduced in #3573) will
receive a glibc-floor callout section once #3573 merges — adding it here
would conflict with #3573's open branch.
Context: #2548, #2982.

The release notes extraction failed on two counts: awk errors when
CHANGELOG.md doesn't exist (first release has no changelog), and
head -n -1 is a GNU extension unsupported on macOS runners. Guard
with a file existence check and replace head with sed '$d'.
