proto-bump

Changes the upstream Meshtastic protobufs Maven pin. Protobuf models are not generated in this repo — they come from org.meshtastic:protobufs (Square Wire–built KMP models), pinned in gradle/libs.versions.toml. A bump is a catalog edit + verification, never a hand-edit of generated proto.

Renovate already watches the catalog for new tagged org.meshtastic:protobufs releases and opens the bump PR for you. Use this skill to drive/finish such a bump (verify, audit, adapt call sites), or — the part Renovate can't do — to track an unreleased develop-SNAPSHOT.

Two modes

Pick the mode from the argument / context. If the change you need isn't in any tag yet, it's Mode B.

Mode A — bump to a tagged release (mergeable)

1. Read the current pin: meshtastic-protobufs = "<…>" in gradle/libs.versions.toml. Confirm the target is a real tag at https://github.com/meshtastic/protobufs/releases (or Maven Central), not a SNAPSHOT.
2. Set meshtastic-protobufs = "X.Y.Z".
3. Re-pin cleanup: if the transitive force block (see below) is present in the root build.gradle.kts, remove it — a tagged protobufs is ordered correctly against transitive pins, so the force is unnecessary and misleading once on a release. Also re-check: is takpacket/mqtt now republished against this protobufs? If still pinning an older one, you may need to keep the force (note it in the PR).
4. Verify (step "Verification" below) — including test/allTests.
5. Audit the new additive surface (below).
6. Open a normal (non-draft) PR.

Mode B — track develop-SNAPSHOT (draft only)

1. Set meshtastic-protobufs = "develop-SNAPSHOT".
2. Add the transitive force block to the bottom of the root build.gradle.kts (exact text below). No repository change is needed — settings.gradle.kts already declares the Sonatype maven-snapshots repo (snapshotsOnly()) and JitPack (https://jitpack.io), which is where develop-SNAPSHOT resolves from.
3. Verify — including test/allTests (this is the mode where skipping them bites; see below).
4. Audit the new additive surface.
5. Open the PR as a draft, stating the un-block condition: "merge once protobufs vX.Y.Z is tagged; switch to Mode A (set the tag + remove the force block) first."

The transitive force block (why it exists, exact code)

takpacket-sdk (and the MQTT client) transitively pin a tagged protobufs (e.g. 2.7.25). Gradle ranks 2.7.25 above develop-SNAPSHOT (a numeric component outranks the develop string qualifier), so the test runtime classpath silently downgrades to the tagged proto while the common-metadata compile uses the snapshot. The mismatch throws NoSuchFieldError/NoSuchMethodError on proto-generated classes at test runtime — and crucially assembleDebug/detekt do not catch it; only test/allTests do. The block forces every org.meshtastic:protobufs* variant to the snapshot so compile and runtime agree:

// ─── TEMPORARY: protobufs develop-SNAPSHOT preview (PR #NNNN) ─────────────────────────────────────
// We track the unreleased protobufs develop-SNAPSHOT. takpacket-sdk-jvm transitively pins a tagged
// protobufs, and Gradle ranks the tag > develop-SNAPSHOT (a numeric part outranks the "develop"
// string qualifier). That downgrades the test *runtime* classpath to the tag while the common-metadata
// *compile* uses the snapshot, yielding NoSuchFieldError/NoSuchMethodError on the proto-generated
// classes at test runtime (assembleDebug/detekt don't catch it; test/allTests do). Force every
// protobufs* variant to the snapshot so compile and runtime agree. Safe while atak.proto is unchanged,
// so takpacket's own message ABI stays compatible with the newer protobufs.
// REMOVE once protobufs is tagged (Mode A) / takpacket + mqtt are republished against it.
allprojects {
    configurations.all {
        resolutionStrategy.eachDependency {
            if (requested.group == "org.meshtastic" && requested.name.startsWith("protobufs")) {
                useVersion("develop-SNAPSHOT")
                because("preview #NNNN: override takpacket transitive protobufs pin")
            }
        }
    }
}

Update #NNNN to the current PR. Remove this entire block when returning to a tagged release (Mode A step 3).

Verification (don't skip test/allTests)

Dispatch the gradle-runner subagent (keep the heavy log out of context). The downgrade failure mode above is a runtime classpath problem invisible to compilation, so verification MUST exercise tests:

• kmpSmokeCompile + a broad compile of proto-consuming modules (core:*, feature:*) — catches compile-time breaking changes (renamed/removed fields, changed oneof shapes).
• test and allTests — the only gate that catches the transitive runtime downgrade. Treat a green compile as necessary-but-not-sufficient.

Triage each compile/test failure: adapt this repo's call sites, or, if a break is unexpected, stop and report rather than papering over it.

Audit the new additive surface (recommended)

New proto versions usually add fields/messages the app doesn't consume yet. Diff the new surface against current usage and list what became implementable. Caveat from prior audits: verify each reference directly — automated gap-lists for this repo have been wrong as often as right. Treat the list as candidates, not facts; don't implement them in this PR unless asked.

PR + guardrails

• Write the PR per .github/copilot-pull-request-instructions.md: WHY-first; 🛠️ (or 🌟 if it unlocks a user-facing feature); link the upstream release notes (real URL only); "Testing Performed" = the gradle-runner run including allTests.
• Never hand-edit or vendor generated proto — this repo consumes the Maven artifact only.
• Keep the change minimal: a bump PR is a catalog edit + the force block (Mode B) + necessary call-site adaptations, not a feature.
• Branch off main (the 2.8.0 line) unless told otherwise.
• After a successful change, update the relevant memory pointer (protobufs-sdk-alignment / lora-region-preset-map) so the next session knows the new baseline.
