Reverts #3504 (5284cc1a), rebased over #3538 with CONTRIBUTING.md resolved by hand: the Gates section goes, the nightly-suites paragraph #3538 added stays.

The Gates workflow, the path-based lane selector, the reusable smoke and WASM workflows, and the alert workflow are removed; smoke.yml and wasm.yml return to their pre-#3504 shape, including just test ts riding after the interop matrix.

Kept from #3504: the leaked-session negative control fix in test/smoke/clients/js (startLeak, wait for the extra session, then detach). A full revert reintroduced the race and failed Smoke on this PR.

The revert restored quest/m0/pr-behavioral-gates.md; a second commit abandons it. Nightly smoke plus the per-PR Check and Test stays the policy. The quest listed no issues under Closes, so no label changes.

test/drill/README.md and quest/m0/transport-impairment-profile.md lose their references to the abandoned quest; the quest review PR (#3541) rewrites the latter anyway.

Walkthrough

The Gates workflow, lane selector, gate checks, and related tests were removed. Smoke and WASM workflows now run from direct pull-request triggers with path filters. The smoke workflow always runs the full matrix and includes TypeScript compliance checks. Alert coverage now monitors workflow-call-only workflows. CI documentation was updated. The JavaScript smoke leak control was renamed from startLeak to detachLeaky and no longer checks resource growth.

Priority: ➖ Normal

Merge Risk: 🔵 Low · up to 37034

The CI simplification retains a stale reference to an abandoned workflow policy, and the smoke leak negative control may no longer reliably confirm that a leaked session was established. These are bounded CI and documentation risks but should be corrected before merge.

This reverts commit 5284cc1.

The Gates workflow, the path selector, and the reusable smoke/WASM
workflows came in without a review pass and are being pulled back. The
quest it completed, quest/m0/pr-behavioral-gates.md, returns to the tree.

P2 Badge Wait for the leaked player before detaching

In the --leak --cases detach negative control, detachLeaky now starts the stray player and removes the live player in one command, after which waitForResources accepts the first all-zero sample. The new element's signal effects and certificate/WebTransport setup are asynchronous, so the old session can close and be sampled before the stray session is counted; the control then reports that it unexpectedly passed and fails smoke-media without testing the resource-baseline assertion. Keep leak creation separate and wait until the additional transport or socket is observed before detaching.

Agreed, and it is what failed this PR's Smoke run. a358d80 keeps #3504's media.ts/contract.ts/setup.ts (startLeak, then wait for the extra session, then detach); only the CI machinery is reverted.

The revert brought quest/m0/pr-behavioral-gates.md back. Nightly smoke
plus the per-PR Check and Test stays the policy, so the quest goes.

The revert would reintroduce the race where the negative control samples
a zero-resource instant before the deliberate leak has opened its
session, which is exactly how it failed on this PR's Smoke run. The
harness half of #3504 stays; only the CI machinery goes.

Also drops the last reference to the abandoned gates quest.

P2 Badge Trigger the suites when the shared harness changes

When a PR changes only test/lib/harness.sh, this path filter does not start Smoke, and the restored WASM filter omits it as well, even though test/smoke/smoke.sh, test/wasm/run.sh, and test/ts/run.sh all source that file. The normal Check/Test dispatcher also runs no cross-language recipe for a test/lib/**-only diff, so broken process cleanup or port reservation can merge untested, with WASM potentially remaining broken until an unrelated matching PR. Add test/lib/** to both workflow triggers.

Out of scope for a revert: this restores the workflow to its pre-#3504 shape, and test/lib/harness.sh predates #3504 without ever being in these filters. Fair follow-up though; a one-line paths addition to smoke.yml and wasm.yml in its own PR.

P2 Badge Keep pull-request cache usage restore-only

When Smoke runs for a matching pull request, invoking Swatinem/rust-cache directly leaves its save condition enabled, and cache-on-failure permits writes even from failed runs. Those entries are scoped to the PR while consuming the repository cache quota, contradicting the single-writer policy documented in .github/workflows/cache.yml:6-10 and potentially evicting the shared cache that other PRs can restore. Use the repository's ./.github/actions/rust-cache wrapper here so PR runs remain read-only.

Out of scope for a revert. This is the pre-#3504 cache step, restored verbatim. If the wrapper should replace it, that is a separate change to the workflow, not part of undoing #3504.

P2 Badge Key WASM cancellation by pull request number

When a pull request is merged while WASM is running, the original run uses a refs/pull/.../merge value for github.ref, while the closed event uses the target branch ref. The two events therefore enter different concurrency groups, so the skipped close run cannot perform the cancellation promised above and the old job can consume its full 60-minute allowance after merge. Key the group by github.event.pull_request.number, which is stable across these events.

Out of scope for a revert. The concurrency key is the pre-#3504 one, restored verbatim. Worth its own PR if the post-merge cancellation matters.
