Two reviewers over the #1345/#1348/#1349 wave; no blockers, two majors, several minors — all fixed. - La16 was still billed at 4 B/px: the no-conversion special case keyed on native_bpp == 4, which La16 also is — but only Rgba8 is a real move in into_rgba8, so La16's decode peak is 8. The case now keys on the color type, and a table test pins every layout's peak (plus GIF's screen+frame 8) so the accounting can't silently drift. - A control-routed open of a damaged-but-recoverable drawing parked the operation behind the RecoveryPrompt modal (hang until the JS timeout, silent drop if another op arrived, or false success when a human declined). The open op now settles as failed with recovery_required and the parse error; the prompt stays for humans, automation can retry through the recovery flow. - json_values_match: integers beyond f64 precision compared by value (a u64 could round-trip-match a float); integral pairs now compare exactly and mixed integer/float matches only when the float is whole and equals the integer. - A queued web open settles with the explicit queued marker whenever the open slot was busy (the old name check made same-named in-flight opens look completed with an empty result). - ocs-control.js resolves with the API object reference, not window.ocsControl (undefined if the bridge already existed when the script ran); DATALINK on web says the typed path is superseded by the picker instead of silently discarding it; the wipeout depth test probes past the page background's rectangle; and the plot-path doc comment names the function it actually mirrors.

// Web automation convenience API (#1349).
|
|
//
|
|
// The wasm module exposes the control bridge through `window.wasmBindings`
|
|
// (ocs_control_submit / ocs_control_take). This module wraps it in promises:
|
|
//
|
|
// await window.ocsControl.ready resolves once the bridge exists
|
|
// window.addEventListener("ocs-ready", …) fired once, at the same moment
|
|
// await window.ocsControl.request({...}) one control request -> final reply
|
|
//
|
|
// Hosts that intend to automate from the start should set
|
|
// localStorage["opencadstudio.automation"] = "1" before the page loads so the
|
|
// startup donation prompt never appears (see docs/automation/README.md).
