* 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
Read screenshot identity from the selected frame-tree root instead of a
filtered inventory that could substitute a child. Reuse the frame record
parser for initial and event identities, rejecting malformed roots before
capture while preserving known origin refusals.
Share explicit origin-scope diagnostics across CDP workflows without
changing policy or conflating startup uncertainty, document replacement,
worker protection, and Inspector restrictions. Document the recovery and
make screenshot navigation fixture ordering explicit.
Validation: 577 focused checks passed across 13 files; one platform-specific
invalid-byte-filename case skipped. Build, typecheck, lint, formatting,
generated documentation checks, README conformance, and discovery passed.
No full suite or live browser/provider execution.
