deltic-browser rows: composed artifacts runtime-linked in Chromium - #39
Merged
Conversation
…m; component-test to b402686 The browser half of the deltic legs (lann/deltic#14): deltic-browser + deltic-browser-delegated run both composed artifacts inside headless Chromium through the upstream page driver and polymorph-test's DELTIC worker — the pinned deltic-embedder.mjs release asset links the suite in the browser; no transpile step, no generated tree. The artifacts import only wasi 0.2 and test-context, so the stock upstream worker serves the leg unmodified; this repo's frame is asset wiring, target config, and results writing (driver-ct/deltic/run-browser.mjs, its own npm tree — no jco dependency). fetch-translator.ts grows an --asset selector for the embedder bundle. Matrix: 11 targets, deltic-browser rows identical to jco-browser case for case. Co-dependent: the component-test pin moves to b402686 (the deltic worker ships there), whose repo went jco-free and deleted the component-test-jco-transpile bin — the thin wrapper is vendored into driver-ct/jco/ (it resolves this repo's own pinned jco-transpile, and it is deleted with the jco tree when that leg retires). Gates: just check; conformance-ct::all with CONFORMANCE_BROWSER=1 (70 results, 0 failing), matrix-check green. Leg wall times on this box: jco-browser 2.4s, deltic-browser 2.7s.

jco support/coverage is retiring family-wide, retained only in polymorph-webcrypto (operator ruling recorded on lann/deltic#14). The deltic rows cover both former postures — stock Deno (deltic-deno*) and headless Chromium (deltic-browser*, #39) — so the four jco targets come out: conformance/driver-ct/jco/, their targets.toml blocks, the justfile recipes and aggregate/pins wiring, the CI Node step and jco js-lock, and the .gitignore entries. matrix.md regenerated for the surviving seven targets (42 results, 0 failing). Also, while touching those lines: the CI publish action's results list gains the deltic-browser rows it missed in #39 (the local aggregate recipe already passed them — the same completion #38 made for the deno rows), and conformance/README's targets table gains the same rows. Gates: gha::rust-checks, gha::smoke, CONFORMANCE_BROWSER=1 gha::conformance-checks (7 targets / 42 results / 0 failing), gha::interop — all green locally. The post-gate touch-up was the CI-yaml results list only (not locally executable).

…ostures" This reverts commit 677daac (PR #40, reverse of 8b16928): the jco legs return until the perf comparison against the deltic legs has been run (operator call, 2026-08-10 — lann/deltic#17 is the tracking issue; the family ruling that jco support ultimately remains only in polymorph-webcrypto stands, lann/deltic#14). The two #39 wiring completions that rode PR #40 (the publish action's deltic-browser results rows, conformance/README's deltic-browser table rows) are re-applied in the follow-up commit rather than lost with the revert.

The publish action's results list keeps the deltic-browser rows and the setup action's js-locks gains deltic's lockfile (both missing since #39 — the local justfile wiring already had them), and conformance/README's targets table keeps its deltic-browser rows. Content-identical to what PR #40 carried alongside the removal.

The deltic rows have run green beside the jco rows since #36/#39, on stock engines (Deno; Chromium via the upstream page driver) with no transpile step and no JSPI flag. With deltic now the family's JS host, the jco driver tree, its fork pin, and the jco-node/jco-browser targets retire; the standing matrix is wasmtime + deltic-deno + deltic-browser over both signer postures (jco-era matrix history stays in git). Node 24 stays in CI: the deltic browser driver runs under it.

The browser half of the deltic legs (lann/deltic#14):
deltic-browser+deltic-browser-delegatedrun both composed artifacts inside headless Chromium through the upstream page driver and polymorph-test's deltic worker — the pinneddeltic-embedder.mjsrelease asset links the suite in the browser. No transpile step, no generated tree; the artifacts import only wasi 0.2 + test-context, so the stock upstream worker serves the leg unmodified. This repo's frame: asset wiring, target config, results writing (driver-ct/deltic/run-browser.mjs, own npm tree — no jco dependency).Co-dependent (named per the sizing rule): the component-test pin moves to
b402686(the deltic worker ships there). That repo is jco-free and deleted itscomponent-test-jco-transpilebin, so the thin wrapper is vendored intodriver-ct/jco/— it resolves this repo's own pinnedjco-transpileand retires with the jco tree.Matrix: 11 targets, 70 results, 0 failing — deltic-browser rows identical to jco-browser case for case. First-order perf (same box, warm): jco-browser 2.4 s, deltic-browser 2.7 s wall for both compositions.
