chore: define per-crate code owners

[QuantumExplorer]

Issue being fixed or feature implemented

The previous CODEOWNERS covered 13 paths. Everything else — including rs-drive-abci, rs-drive, rs-dpp, dashmate, kotlin-sdk, wasm-dpp and the whole JS surface — fell through to * @QuantumExplorer, a single owner. With require_code_owner_reviews: true and required_approving_review_count: 1 on v4.2-dev, v4.1-dev and master, that made one person the only legitimate approver for most of the repo.

Goal: every substantial package has at least two people who can unblock it, and review requests land on people with real context.

What was done?

Every package over ~10k LOC gets an explicit rule. Assignments were derived from non-merge commit history since 2025-01-01 per package path, with bot authors folded into their principals. The 27 remaining packages are all sub-threshold and stay on the fallback — which now names two owners instead of one.

Rules name teams rather than individuals, so review load shifts by changing team membership instead of editing this file. It also enables GitHub's per-team code review assignment to route requests to a subset of members while every member keeps the ability to approve.

Area	Owner
rs-drive-abci, rs-drive, rs-dpp, rs-platform-version, Cargo.toml	@dashpay/drive-owners
rs-drive-proof-verifier	@dashpay/drive-owners + @lklimek
rs-platform-value	@QuantumExplorer
rs-dapi, rs-dapi-client, dapi-grpc/protos, rs-sdk*, wasm-*, dash-platform-queries	@dashpay/sdk-owners
rs-platform-wallet{,-ffi,-storage}	@dashpay/wallet-owners
swift-sdk, kotlin-sdk, rs-unified-sdk-jni	@dashpay/mobile-team
dashmate, dapi, js-*, wallet-lib, dash-spv, platform-test-suite, bench-suite	@dashpay/js-owners
.github/workflows	@dashpay/infra-team + @shumkov

⚠️ Required before merge — teams must exist and have write access

A CODEOWNERS entry naming a team without write access on this repo is invalid, and the rule does not function as ownership. 30 of the 34 rules here point at teams, so merging before this is done leaves most of the file inert.

Create (4):

Team	Members
@dashpay/drive-owners	QuantumExplorer, shumkov
@dashpay/sdk-owners	QuantumExplorer, shumkov, lklimek
@dashpay/wallet-owners	QuantumExplorer, shumkov, lklimek, llbartekll, ZocoLini, bezibalazs
@dashpay/js-owners	shumkov

Grant write access (2): @dashpay/mobile-team and @dashpay/infra-team both exist but currently have no access to this repo.

After merge, verify at https://github.com/dashpay/platform/codeowners — that view lists every unresolvable entry.

How Has This Been Tested?

• Every path in the file was checked to resolve against the working tree (34/34).
• The ruleset was simulated against all 73 currently-open PRs using their changed-file lists, applying last-match-wins. Result: 0 PRs where a single person is the only possible approver, versus the previous file where most of the repo funnelled to one owner. 9 of those file lists were truncated at the API's 100-file cap, which can only under-count paths, so this is a conservative result.
• @bezibalazs is included in wallet-owners on the strength of 9 commits in rs-platform-wallet-ffi; he is also the top contributor to rs-unified-sdk-jni (36) and co-top on kotlin-sdk (58) but is currently in no org team — worth adding him to @dashpay/mobile-team separately.

Breaking Changes

None to code. This changes who is required to approve PRs; some contributors gain and others lose the ability to unblock specific paths.

Two follow-ups, both outside this PR:

• @HashEngineering has read-only access. He is in mobile-team and authors several open mobile PRs, but read-level collaborators cannot function as code owners, so his membership confers nothing until he is granted write.
• @PastaPastaPasta and @thephez are no longer owners of any path (previously reachable via the catch-all). Neither is blocked on their own PRs — GitHub does not permit self-approval regardless — but they can no longer unblock others in SDK/CI and wasm-sdk respectively.

Walkthrough

CODEOWNERS now documents last-match-wins behavior and assigns fallback or path-specific owners for consensus, DAPI, SDK, wallet, mobile, JavaScript, and build/CI areas.

Merge Risk: 🟡 Moderate · up to 5bd8e

The PR routes most ownership through teams, but it is not merge-ready until those teams are created and granted repository write access; otherwise the new ownership rules will not function. The branch-protection wording also needs a minor verification.

Verify or narrow the branch-protection statement.

CODEOWNERS defines path ownership. It does not set the repository approval count. This statement is accurate only if the protected branch or ruleset currently requires one code-owner approval. Verify that setting, or distinguish CODEOWNERS behavior from branch-protection policy. GitHub documents that any listed owner can satisfy the code-owner requirement when multiple owners are configured. (docs.github.com)

Proposed wording

-# Only ONE owner's approval is needed per changed path (branch protection
-# requires 1 approving review from a code owner).
+# When code-owner review is enabled, any listed owner can satisfy the
+# code-owner requirement. Branch protection controls the total approval count.

Preliminary review — Codex only

The ownership split is clear, but GitHub currently rejects all six referenced teams, so the intended routing does not work at this exact head. The documented setup also leaves rs-platform-value and the JavaScript ownership group with only one possible approver, contrary to the PR's explicit two-person goal. Source: Codex reviewer backend (exact model ID not supplied in the evidence); Claude verifier backend (exact model ID not exposed to this agent); openclaw-agent/cliproxy/gpt-5.6-sol is orchestration-only and not reviewer evidence.

Validated blockers were found in the Codex precheck. Opus is deferred until a fresh Codex revalidation clears the blocker gate.

  Two explicit ownership assignments still preserve the single-person bottleneck this PR is intended to remove. Line 18 overrides the two-person fallback for `rs-platform-value` with only `@QuantumExplorer`, while lines 47-56 assign the JavaScript packages solely to `@dashpay/js-owners`; the required provisioning plan lists only `@shumkov` as that team's member. Because one code-owner approval satisfies the configured requirement, a PR confined to either group can still be unblocked by only one person. Add a second valid owner to the `rs-platform-value` rule and at least one additional write-enabled maintainer to `js-owners`, or list a second valid owner directly on the JavaScript rules.
