leasePort({closed:true}) ignored its option: it probed an ephemeral port and
closed it, so a parallel test file could bind it and answer a request the
test expected to fail (preview.test.mjs:209 saw 200 instead of 502).
leaseClosedPort holds a bound, non-listening socket in a perl child until the
test's after hook. Connects still get ECONNREFUSED, bind() from another
process gets EADDRINUSE, and the kernel's ephemeral allocation skips the port.
Lane mode keeps its band and per-port lock, and releases the socket before
the lock. leasePort now refuses a closed option, so a stale call cannot get
the unheld port again.
Unanswerable callers (webui preview, serve, service) move to leaseClosedPort(t).
Callers that listen on the port themselves (stack-release rehearse, control-board
serve, tester-cli) keep leasePort and drop the ignored option.
Jason's Q168: a visual editor for the Console's project documents,
held to row 148's rendering rules.
Library. ProseMirror with prosemirror-markdown and markdown-it, chosen
in the phase 1 library report (LIBRARY.md, REPORT.md in the packet).
packages/webui/third_party/editor/ holds 19 upstream packages as source,
byte for byte, each with its license, plus NOTICE and PROVENANCE.json.
Build. packages/webui/editor/ holds the model, view, entry and
build.mjs. esbuild 0.28.2 is an exact devDependency of packages/webui
with its own lock; editor/toolchain.mjs checks the version and the
binary's sha256 before any build. MOSAIC_REQUIRE_EDITOR_BUILD=1 turns a
missing or different esbuild into a failure, and the rebuild test then
checks the committed src/public/editor.js and editor.css match a fresh
build. The built bundle is committed under Mos's conditions
(mos-0755, mos-0765).
Console. The docs view gets Visual and Source modes. A save still
writes Markdown through the existing project write path, with the same
stale-base and read-only handling. A mode switch reuses the draft and
reads nothing from the project. Links and images keep row 148's
target rules, and no raw HTML runs. serve.mjs serves /editor.js and
/editor.css; index.html loads them.

Round 5 is a rebase onto d88613bac (row 155); only docs/TOOLS.md,
webui/README.md, public/bus.js and serve.mjs differ from the round
before. Reviewers on candidate manifest 3a4bc21c...3b05: Dewey
(security) approve 29027, Filbert approve 29026. Mos's decision 123 go
for public.diff 902f0244 (handwritten part ea59079e): mos-0824. Sage gate
on 72c3fa598 with MOSAIC_REQUIRE_EDITOR_BUILD=1: GATE_PASSED 25/25
(node 2397, selftests 422), 22:07:29Z to 22:13:50Z; the rebuild test
ran and passed.
Nothing live.
The console takes the design package's tokens.css and icons.svg as byte
copies, guarded by a test, and a new shell.css holds the components:
command bar with freshness line, section list (a strip that scrolls
inside itself below 760px), dense table, inspector, status mark, chips,
copy command, toast, Ctrl+K palette, not found, banners and skeleton
rows. JetBrains Mono 2.304 ships from the official archive with sha256
and OFL. Harbor following the system setting is the default palette.
A refusal (403, not-configured, no-bus-host, or the board's 403) fails
closed everywhere: no kept rows, counts, inspector, palette entries or
conversation history, and a later 500 or 503 doesn't bring them back.
Dewey built it in three rounds. Round 1 (75569953) and round 2
(78c3aef9) got changes from Darkwing (27148, 27165) and Filbert (27143,
27163) for refusal leaks outside the main view; round 3 (2562c05d) was
approved by Darkwing (27171) and Filbert (27174). Sage's gate on
ea080fd8 plus the candidate: runs 41/0, queue 148/0, webui 27/0,
conversation 182/0, control-board 124/0, build-tokens --check current,
every scripts/test-*.sh 0 failed (task 98/0 and release 14/0 with
Docker). The round 2 gate had one discord engine timing failure in the
full run, 66/0 alone, filed as #1553.

History opens a seat's conversation from the Waiting card, table row
and inspector. It pages the whole branch through the CHAT-02 board
routes, renders untrusted text inert, polls with the follow cursor, and
marks every switch (branch, newer, reconcile, gone). The WebUI proxy
passes only the two conversation routes' queries upstream.
Dewey authored it. Filbert asked for changes on r1 (24b046af) and
approved r2 (d06de6a7) in review 160dd68d. A relaunch shows 'newer',
not 'reconcile', a deviation from brief 2.3 item 6 that Filbert
accepted.
