* fix(browser): type CDP command replies and parse frame trees once
CdpConnection.send is typed by method name. A command registered in
src/browser/protocol/CdpCommands.ts has its parameters typed from the
protocol table Playwright ships and its reply parsed once by its own result
schema; a mismatch rejects that command with CdpMalformedReply
(protocol_error, command, JSON pointer) without poisoning the connection.
Playwright storage sessions admit replies through the same table.
Page.getFrameTree and Page.getResourceTree are the first registered
commands. Their one parser keeps per-frame facts tolerant (malformed child
entries remain explicit omissions) and replaces the per-site readers:
observeMainFrameUrl, mainFrameUrl, walkFrameTrees, frameTreeResources,
runtimeFrameTreeSchema and the scenario storage frame schema.
A reply without a frame tree used to be retried for two seconds and
reported as target_not_allowed; it is now one protocol_error.
A guard test counts literal CDP command names without a result schema per
source file; the baseline can only shrink.
* fix(browser): consume parsed CDP facts across boundaries
Own operation results and exact rejections in withVerifierCleanup, including
undefined, null and independent cleanup failures. Remove the optional-primary
cleanup contract and migrate every caller, preserving returns, annotations,
signal restoration and dependent cleanup order.
Make Frida/JEB reporters fail on reasonless rejections and retain JEB fixture
files while provider cleanup is incomplete. Own the nested packaged WASM
verifier and expose its composite process/root cleanup capability for retry.
Update runnable docs and isolated fixture dependencies.
Validation: 547 focused cases in 20 files, eight isolated boundary unit checks,
static/build/docs/discovery gates and duplication check (3.58%). Node process,
SDK and descriptor cleanup are exercised; provider and packaging results in
orchestration tests are simulated. Pack/install subprocess ownership remains
with the existing shared package runner outside the nested-command change.
Wait for the restored document's matching CDP load event before closing the observer. Drain storage verifier providers and surface cleanup failures so the next scenario receives a settled page.
