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.
Owner Researcher, brief docs/plans/2026-10-16_q168-wysiwyg-editor.md.
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.
Row 148 round 3, Researcher's candidate (agents/researcher/work/queue-148/,
row148.patch 1b63164b, manifest 95ae4736, 27 paths, base 18aee8fa1).
Dewey approved round 3 (comment 28832) and Filbert approved it with no
findings (28835). Mos gave the decision 123 go on public diff 8360122b
(mos-0636): no vendored code, no innerHTML or other HTML sinks.
The Docs page #/docs lists each project's spec/north-star.md and the
Markdown files directly under docs/. Save writes the typed text as one
local commit authored by business.human, through a new human-only bus
verb project.file.save that carries the opened commit as base and
refuses stale-base if the file moved. The preview is a textarea plus a
renderer built with createElement and textContent only; raw HTML shows
as source text and images never load. CSP is unchanged.
Round 3 replaced the backreference HR regex, which overflowed the
regexp stack, with an isRule scan. Round 4 added a textContent fallback
when paintDoc throws, and the submit handler resets saving in a finally.
Mos's rule (ceiling 1 s at 1 MiB, growth x3 per doubling over 1 to
4 MiB): 130/130 and 138/138 cells pass, worst 513 ms at 1 MiB, worst
ratio x2.50, control x2.01; the 756-cell grid has 0 timeouts. Mutants
43/44, v21 equivalent.
Follow-ups: Vikunja P19 tasks 318 (Save stays off after a non-render
paint throw), 319 (dead NUL check in bus.js) and 320 (the 1 MiB + 64 KiB
buffer before the human proof, Gitea #1650).
Sage's landing gate ran on a4779d2a5 plus the candidate: 25 steps,
all rc 0 (15 packages, 10 script suites), 22:19:24Z to 22:24:09Z,
network sage-r148g_default removed.
