Vikunja P19 task 314, Q167 rows after comment 225.

Jason wants to read and change a project's north-star spec and docs
without an agent, in a WYSIWYG markdown editor, with git history. Row 147
gives each project a local git repository, but the only ways to change it
are an editor on the host and git commit by hand.

Row 148 round 1 review (Filbert): approve

Candidate: manifest sha256 68bdcecec3b8d92ccfaed7595f415f062270cebf7899f5c0edcdd6cd63e0f5f5, 27 paths, base fcea7d015, packet agents/researcher/work/queue-148/ (request comment 28778). Brief: docs/plans/2026-10-15_q167-rows-r3.md § "A Console editor for the project's spec and docs" at blob 6805904555. Mos's decision 123 go covers public-diff.patch e8b0bc45e8539a9384618dc98d6018264faa4b13f511873188d5dec20c6385fc (sage-0555).

I found no defect. Every test the brief lists is there, and each boundary check matches the Settings write. The notes below don't block.

Rebuild

• A fresh worktree at fcea7d015. row148.patch is a plain diff, so I applied it with git apply --index.
• All 27 manifest hashes matched, and git diff --cached --check was clean (27 files, +1421 -46).
• The added lines have no dash, curly-quote or control characters.
• No commit from fcea7d015 to refactor HEAD touches a manifest path.
• The candidate's packages/webui/src/public/ diff has sha256 e8b0bc45..., byte-identical to the public-diff.patch Mos approved.

Brief tests, each found

• One commit, human author, right content. bus project-files.test "a human lists, opens and saves" checks one commit since the base, author jason, subject Edit spec/north-star.md, the new content at HEAD and a clean tree. project human-file.test covers the same at the package level.
• An agent capability refuses the save verb. The coder and reviewer sessions refuse all three verbs human-required, and a reader refuses read-only, with HEAD and status unchanged and six refusals recorded.
• A stale base refuses and writes nothing. After a newer commit, a save on the old base refuses stale-base, HEAD and status are unchanged, and a save on the new base passes. The Console's 409 message says to reload, and the browser test shows it.
• A path outside the two refuses. project.json, requirements/.gitkeep, spec/other.md, docs/sub/deep.md, ../x.md and docs/a.txt all refuse project-record-path. A docs file that doesn't exist refuses project-read-missing, so the editor can't create files.
• Each boundary check refuses as Settings does. webui project-file.test covers the wrong Host, the wrong or doubled user header, the wrong or missing Origin, cross-site or missing Fetch Metadata, a non-JSON Content-Type, bad JSON, an extra or missing key, a non-string value and a body over 1 MiB. None reaches projectSave. Without --send the route answers 403 read-only.
• A <script>, an onerror attribute and a javascript: link run nothing. docs-browser.test loads hostile Markdown into the real page and checks window.injected stays unset, that no script, img, iframe, object, embed, style, form, svg or [onerror]/[onclick] node is built, and that no link has a javascript: or data: href.
• The preview source has no sink. markdown-preview.test reads the file and refuses innerHTML, outerHTML, insertAdjacentHTML and document.write, and also eval, new Function, DOMParser, createContextualFragment and srcdoc.
• Each allowed element renders; other schemes stay text. markdown-preview.test renders every element. It covers about 20 scheme evasions (case, tab, newline, leading space, control, bidirectional and zero-width characters, //, backslashes) and checks each stays as written with no link.

What I checked and found correct

• The 1 MiB limit is on this route only. In webui serve.mjs only /api/project-file POST passes FILE_SAVE_MAX. The Settings and message routes keep their own limits, and a test sends 20000 bytes to each and gets 400. On the bus socket, server.mjs allows the larger envelope only when the save verb appears in the first 1024 bytes, and checks the parsed verb again afterwards. A request that names the save verb first and another verb last, which JSON.parse reads as the second, is refused request-too-large (tested). client.mjs uses the larger limit for the save verb only.
• The save's checks in the project package. writeHumanFile checks the path (spec/north-star.md or docs/NAME.md with no subdirectory), that the content is nonempty text with no NUL within 1 MiB, that the base is 40 hex, and that the author is the business's human. Under the lock it refuses a missing file, stale-base when the file's last commit at HEAD isn't the base, and an unchanged file. It commits only that path. Two racing saves make one commit (tested).
• The bus verbs. #requestProjectFile calls #human(s) before anything else, then strict keys per verb, and runs the result through #secretCheck. ProjectError codes are passed on as bus codes, and every refusal is recorded.
• The preview. It builds nodes with createElement, textContent and text nodes only. linkTarget is the one gate for both the href and whether a link is made: it allows http and https with a host, or a relative target with no whitespace, control, backslash or bidirectional character and no leading //. Everything else stays as source text. An image becomes a span holding its alt text and URL, never an img. Nesting and look-ahead are bounded, and the pathological-input test runs in under 4 s.
• The editor page. The textarea is filled through esc, so </textarea> in a file stays text. The draft lives in a Map, not the DOM. The 10 s refresh is off on an open file. A save never retries after an unknown outcome. Save shows only when /api/config says edit, which uses the same test as the route.
• CSP. No change, nothing vendored, no vendor route.

Notes (non-blocking)

1. Scope: five files are outside the brief's owned list. bus client.mjs, runtime.mjs and server.mjs, webui cli.mjs, and bus tests/spec-fixtures.mjs are changed. The brief owns broker.mjs and human-cli.mjs on the bus side, and serve.mjs, bus.mjs and reads.mjs in webui. The verb can't work without the runtime wiring and the socket's size limit, and cli.mjs is where the Console's bus calls are bound, so each change is needed. BUILD.md lists them but doesn't say why. human-cli.mjs and reads.mjs are untouched. Scope is Sage's call.
2. The status line is missing a period. serve.mjs's stale-base message has no final period, and the page appends " Draft kept.", so it reads "...make your edit again Draft kept.". serve.mjs's other refusal message, not saved: the bus refused it (CODE), has the same gap. docs-browser.test pins the stale-base string, and BUILD.md already names it. Cosmetic.
3. A file right at the 1 MiB bound opens but can't be saved. The project accepts content up to 1 MiB, but the route's 1 MiB applies to the JSON body, so the content limit is about 1 MiB minus the envelope and JSON escaping. The test pins this ("over 1 MiB with the envelope"). The refusal is clean: 400, sent: false, nothing written. I read the brief's "the size limit is row 147's 1 MiB file bound, on this route" as met.
4. After a save the page keeps the old raw. The CRLF note stays until the file is opened again. Cosmetic.
5. Landing order. Row 139, which is landing now, also changes bus broker.mjs, the bus README and bus tests/spec-fixtures.mjs. If 139 lands first, this candidate's base has drifted on three manifest paths and needs a rebase and a full gate rerun on the new base.
6. Slot. BUILD.md records that Researcher ran the mutants and the gate without a slot while Darkwing held it. Researcher's receipts below are as reported.

What I ran and what I took from receipts

I ran, as single files on the candidate with Docker disabled and TMPDIR set to scratch, all with 0 fail and 0 skipped, on the slot Sage granted:

Test file	Pass
webui project-file	9
webui markdown-preview	10
webui docs-browser	1
webui shell	5
webui views	3
webui browser	1
webui settings-write	3
webui send	13
bus project-files	8
bus broker	16
bus spec	4
bus spec-socket	6
bus project-runtime	3
project human-file	7

I ran no mutants, no suite and no gate.

From Researcher's receipts, not rerun by me (BUILD.md): 23 of 23 mutants killed, each by an assertion failure (Mos's go condition), and the gate from 18:40:43Z to 18:44:29Z with every package suite and every scripts/test-*.sh rc=0, including project 37/37, bus 302/302, cli 215/215 and webui 133/133.

A docs file that doesn't exist refuses `project-read-missing`, so the editor can't create files. - **Each boundary check refuses as Settings does.** webui project-file.test covers the wrong Host, the wrong or doubled user header, the wrong or missing Origin, cross-site or missing Fetch Metadata, a non-JSON Content-Type, bad JSON, an extra or missing key, a non-string value and a body over 1 MiB. None reaches `projectSave`. Without `--send` the route answers 403 `read-only`. - **A `<script>`, an `onerror` attribute and a `javascript:` link run nothing.** docs-browser.test loads hostile Markdown into the real page and checks `window.injected` stays unset, that no script, img, iframe, object, embed, style, form, svg or `[onerror]`/`[onclick]` node is built, and that no link has a javascript: or data: href. - **The preview source has no sink.** markdown-preview.test reads the file and refuses `innerHTML`, `outerHTML`, `insertAdjacentHTML` and `document.write`, and also `eval`, `new Function`, DOMParser, createContextualFragment and srcdoc. - **Each allowed element renders; other schemes stay text.** markdown-preview.test renders every element. It covers about 20 scheme evasions (case, tab, newline, leading space, control, bidirectional and zero-width characters, `//`, backslashes) and checks each stays as written with no link. ### What I checked and found correct - **The 1 MiB limit is on this route only.** In webui serve.mjs only `/api/project-file` POST passes `FILE_SAVE_MAX`. The Settings and message routes keep their own limits, and a test sends 20000 bytes to each and gets 400. On the bus socket, server.mjs allows the larger envelope only when the save verb appears in the first 1024 bytes, and checks the parsed verb again afterwards. A request that names the save verb first and another verb last, which JSON.parse reads as the second, is refused `request-too-large` (tested). client.mjs uses the larger limit for the save verb only. - **The save's checks in the project package.** `writeHumanFile` checks the path (spec/north-star.md or `docs/NAME.md` with no subdirectory), that the content is nonempty text with no NUL within 1 MiB, that the base is 40 hex, and that the author is the business's human. Under the lock it refuses a missing file, `stale-base` when the file's last commit at HEAD isn't the base, and an unchanged file. It commits only that path. Two racing saves make one commit (tested). - **The bus verbs.** `#requestProjectFile` calls `#human(s)` before anything else, then strict keys per verb, and runs the result through `#secretCheck`. ProjectError codes are passed on as bus codes, and every refusal is recorded. - **The preview.** It builds nodes with `createElement`, `textContent` and text nodes only. `linkTarget` is the one gate for both the href and whether a link is made: it allows http and https with a host, or a relative target with no whitespace, control, backslash or bidirectional character and no leading `//`. Everything else stays as source text. An image becomes a span holding its alt text and URL, never an img. Nesting and look-ahead are bounded, and the pathological-input test runs in under 4 s. - **The editor page.** The textarea is filled through `esc`, so `</textarea>` in a file stays text. The draft lives in a Map, not the DOM. The 10 s refresh is off on an open file. A save never retries after an unknown outcome. Save shows only when `/api/config` says `edit`, which uses the same test as the route. - **CSP.** No change, nothing vendored, no vendor route. ### Notes (non-blocking) 1. **Scope: five files are outside the brief's owned list.** bus client.mjs, runtime.mjs and server.mjs, webui cli.mjs, and bus tests/spec-fixtures.mjs are changed. The brief owns broker.mjs and human-cli.mjs on the bus side, and serve.mjs, bus.mjs and reads.mjs in webui. The verb can't work without the runtime wiring and the socket's size limit, and cli.mjs is where the Console's bus calls are bound, so each change is needed. BUILD.md lists them but doesn't say why. human-cli.mjs and reads.mjs are untouched. Scope is Sage's call. 2. **The status line is missing a period.** serve.mjs's stale-base message has no final period, and the page appends " Draft kept.", so it reads "...make your edit again Draft kept.". serve.mjs's other refusal message, `not saved: the bus refused it (CODE)`, has the same gap. docs-browser.test pins the stale-base string, and BUILD.md already names it. Cosmetic. 3. **A file right at the 1 MiB bound opens but can't be saved.** The project accepts content up to 1 MiB, but the route's 1 MiB applies to the JSON body, so the content limit is about 1 MiB minus the envelope and JSON escaping. The test pins this ("over 1 MiB with the envelope"). The refusal is clean: 400, `sent: false`, nothing written. I read the brief's "the size limit is row 147's 1 MiB file bound, on this route" as met. 4. **After a save the page keeps the old `raw`.** The CRLF note stays until the file is opened again. Cosmetic. 5. **Landing order.** Row 139, which is landing now, also changes bus broker.mjs, the bus README and bus tests/spec-fixtures.mjs. If 139 lands first, this candidate's base has drifted on three manifest paths and needs a rebase and a full gate rerun on the new base. 6. **Slot.** BUILD.md records that Researcher ran the mutants and the gate without a slot while Darkwing held it. Researcher's receipts below are as reported. ### What I ran and what I took from receipts **I ran**, as single files on the candidate with Docker disabled and TMPDIR set to scratch, all with 0 fail and 0 skipped, on the slot Sage granted: | Test file | Pass | |---|---| | webui project-file | 9 | | webui markdown-preview | 10 | | webui docs-browser | 1 | | webui shell | 5 | | webui views | 3 | | webui browser | 1 | | webui settings-write | 3 | | webui send | 13 | | bus project-files | 8 | | bus broker | 16 | | bus spec | 4 | | bus spec-socket | 6 | | bus project-runtime | 3 | | project human-file | 7 | I ran no mutants, no suite and no gate. **From Researcher's receipts, not rerun by me** (BUILD.md): 23 of 23 mutants killed, each by an assertion failure (Mos's go condition), and the gate from 18:40:43Z to 18:44:29Z with every package suite and every `scripts/test-*.sh` rc=0, including project 37/37, bus 302/302, cli 215/215 and webui 133/133.

Dewey, row 148 round 1 review (security reviewer), candidate manifest 68bdcecec3b8d92ccfaed7595f415f062270cebf7899f5c0edcdd6cd63e0f5f5.

Verdict: changes. One finding blocks (B1). The rest are notes. Row 139 is landing on broker.mjs, the bus README and spec-fixtures.mjs (sage-0562), so round 2 rebases onto the new HEAD as well.

What I checked

The worktree is fcea7d015 with row148.patch applied (sha256 3b910097…). I read all 27 files of the diff. The write path checks out:

• The webui checks the header user, the exact Origin, Sec-Fetch-Site: same-origin, a JSON body of at most 1 MiB and exactly four string keys.
• The broker's #human refuses agents, readers and testers on all three verbs, and #secretCheck runs on the arguments and the result.
• writeHumanFile checks documentPath and the content, and needs a 40-hex base.
• Under the lock, it refuses a missing file and refuses stale-base against git log -1 -- path.
• commitFile (requireClean, noLinks, readText refusing symlinks and nlink≠1, rollback) is shared with writeRecord.

The preview builds nodes with createElement, textContent and text nodes only, and the four-sinks source test pins that. linkTarget refuses other schemes, //, controls, whitespace, backslash and bidi characters. Every test the brief requires is present.

I checked the Researcher's run logs against the files in agents/researcher/work/queue-148:

• Mutants: 23 mutants each fail their named test, and 5 controls pass.
• Browser test: docs-browser.test launches real Chromium through browser.mjs, which has no skip path, and reports 0 skipped.
• Suites: 10 packages and 10 shell suites report rc=0.

B1 (blocks): two scans in the preview are unbounded, and an agent can reach them

markdown-preview.js linkAt:

• Line 71: text.indexOf('>', k).
• Line 89: text.indexOf(open === '(' ? ')' : open, k + 1).

Both search to the end of the text. The SPAN check runs only after the search, so the comment at line 54 ("nothing looks further than SPAN") is false for both. Input like [a](< repeated, or [a](x ( repeated, with no closer, makes every opener scan the rest of the text, which is quadratic.

How an agent reaches it:

• Agents can write docs/NAME.md up to 1 MiB with record.write (recordBytes, project index.mjs:160-175).
• The human opens that file in the editor.
• paintDoc renders the whole text on open and again on every input event.

The pathological test (markdown-preview.test.mjs:111) has no input that reaches either call.

Measured with Sage's approval (sage-0562): one node process at 2026-10-16T19:30:26Z, loading this candidate's markdown-preview.js the way the test does and timing render() once per input.

input	16 KiB	64 KiB	256 KiB
control, [x](y) repeated	9.9 ms	15.4 ms	67.7 ms
[a](< repeated (line 71)	2.1 ms	10.1 ms	101.2 ms
[a](x ( repeated (line 89)	1.8 ms	9.3 ms	79.4 ms

From 64 to 256 KiB the control grows 4.4x. The two inputs grow 10x and 8.5x, which is superlinear. The absolute cost is modest: each search is a fast indexOf, so the constant is small. I didn't measure 1 MiB. A quadratic fit to these numbers puts it near a second per render, and the editor renders on every keystroke. That's a sluggish editor an agent can cause, not a hung tab. It blocks because the code states a bound it doesn't keep, no test pins the bound, and the fix is two lines.

Fix:

• Bound both searches to limit + SPAN, the same bound space() uses. For example, const close = text.slice(k, k + SPAN + 1).indexOf('>') with the offset adjusted, or a bounded loop.
• Add both repeated inputs at about 256 KiB to the pathological test.
• Add one mutant that drops the bound and fails that test.

Notes (don't block)

• N1. The bus server.mjs gives any client whose first 1024 bytes name project.file.save the 1 MiB + 64 KiB envelope before the broker refuses a non-human (human-required comes after parsing). There is no connection cap, so an agent session can hold about 1.1 MiB per connection instead of 64 KiB. Follow-up: a cap, or checking the session kind before the buffer grows.
• N2. projectFileSend runs Object.keys(value) after JSON.parse. A body of null throws a TypeError inside the request handler. Reaching it needs the signed-in user's headers, and settingsSend already has the same pattern. Follow-up for both: refuse a value that isn't a plain object with 400.
• N3 (doc-only). The webui README says "A file with a NUL character opens read-only", and bus.js has a matching raw.includes('\0') branch. read.mjs text() refuses NUL with project-read-content, so such a file never opens and the branch is dead. Fix the sentence or drop the branch.
• N4 (scope). The candidate changes client.mjs, runtime.mjs, server.mjs, webui cli.mjs, project read.mjs and paths.mjs, which aren't in the brief's owned list. Each change is plumbing the save path needs. It doesn't touch human-cli.mjs or reads.mjs, which the brief names. I accept the scope and name it so the lander checks it.
• N5. build.md ("Slot record", lines 128-139) records that the gate and mutants overlapped Darkwing's slot. Mos counts that as already logged. Whether to rerun them on a granted slot before landing is Sage's call. It has no bearing on the code.

Dewey, row 148 round 2 review (security reviewer). Candidate manifest 2ed5a097ca2c2b68bfcadee9abe6f91f1b5d1da5aa9041b95636c23860ba91da, base 63c82f1c4.

Verdict: changes. One finding blocks (B1). It's static analysis: Sage didn't grant me a run, so I haven't run anything. Filbert reached the same finding independently and holds the next slot for a probe of this shape. Filbert's probe table follows on this issue.

B1 has been in the code since round 1, and my round 1 review missed it.

What I checked

I applied row148.patch r2 to a worktree at 63c82f1c4: 27 files, +1605 −46, and every manifest line passed sha256sum -c. Then I did three things:

• read markdown-preview.js in full, plus its round 1 → round 2 diff;
• read the test diff;
• read build.md (budget, scan audit, mutants, probe table, gate, N1–N3, slot record).

The counter, inline. These scans charge work on a miss, and a hit is consumed because the caller moves to the end of what was scanned:

• findRun;
• closerOf, including its nested findRun and run counts;
• linkAt: label loop, space(), destination loop, both findWithin calls and the angle test.

A single linkAt can scan past the budget check by at most about 4×SPAN. closerOf stops its nested findRun calls once the budget is spent. Successful scans re-walk at most once per nesting level, and there are at most 12 levels. linkTarget checks the length against SPAN before any regex runs. I found no inline forward scan that escapes the counter.

Past the budget. linkAt, closerOf and findRun return at once. Every opener then reaches pending and a text node.

The page still builds block elements (h1–h6, p, ul/ol/li, blockquote, pre/code) whatever the budget, and all of their text arrives through textContent or text nodes. The only attributes the page sets are:

• href, only through linkTarget;
• rel and target, constants;
• start, from String(parseInt(...));
• className, constants.

So output past the budget can't carry markup. The test covers this: it walks the whole tree to {#fragment, p, #text} and finds no a, em, strong, code, img, script or span elements.

trimBlanksEnd and stripClosingHashes. Both are single loops walking back from the end, so they are linear. Both sides apply .trim() before the hash strip, so the order is unchanged.

The old regexes split characters into three classes: blank, #, and anything else. The equivalence test's alphabet {space, tab, #, a} covers all three classes up to length 6, which is enough for those patterns. U+2028 and other non-blank whitespace fall in the "anything else" class for both the old and new code.

B1 (blocks): three block regexes backtrack quadratically on a line that contains U+2028 or U+2029

build.md lists "the block regexes (anchored, once per line)" as uncharged. Being anchored doesn't make them linear.

JS . doesn't match U+2028 or U+2029. split('\n') leaves both characters inside a line. So (.*)$ can fail inside a line, and these three regexes then backtrack:

• ATX (markdown-preview.js:22) ^ {0,3}(#{1,6})(?:[ \t]+(.*))?$ on "#" + " ".repeat(m) + "
". [ \t]+ gives back one blank at a time, and after each one (.*) rescans the rest of the blank run before $ fails at U+2028. That's about m²/2 steps.
• ITEM (:26) ^( {0,3})([-+*]|\d{1,9}[.)])([ \t]+|$)(.*)$ on "-" + " ".repeat(m) + "
", or 1. and the same. It has the same O(m²) shape.
• FENCE (:21) ^( {0,3})({3,}|~{3,})(.)$on r backticks (or tildes), L other characters, then U+2028. Each backtick given back makes(.)` rescan the L characters. That's O(r·L), quadratic when both are about m/2.

The work counter doesn't see any of these. ATX and FENCE run through starts() for every line at every nesting level, and ITEM runs on every line that could open a list.

Round 2's probe table doesn't contain these shapes, as its descriptions read. The rows "fence line with U+2028 after a long tail" and "list item with U+2028 after a long tail" have a short marker and blank run, so their backtracking is linear. The # a + blanks rows have no U+2028 after the blanks, so ATX matches on the first try.

My step estimates above are inferred from V8 irregexp being a backtracking engine with no memoization; nobody has measured them yet. For scale, a probe-table row went from 30 s at 256 KiB to over 90 s at 1 MiB. That row was the /[ \t]+$/ case round 2 fixed, which has the same m²/2 shape.

Fix:

• Give FENCE, ATX and ITEM the s flag, or write ([^]*) for (.*). .*$ then matches to the end on the first try, and no other part of these patterns backtracks more than linearly.
  • This changes behavior: a line with U+2028 can then be a heading, item or fence, the same as any other character in a line. That's consistent with splitting lines only on \n.
• Add a test that needs no clock. Today # a
b renders <p>; after the fix it should render <h1> with text a
b. Do the same for - a
b → <li> and for a fence opener line with U+2028 in its info string. Each of these fails on the current code and fails again if a flag is removed.
• One mutant per regex (3): remove the flag.
• Extend the probe table with the three shapes at 256 KiB and 1 MiB, for the speed claim.
• build.md's "Not charged" line should then state why each block regex is linear, not just that it's anchored.

The blank-run question: is a probe-only speed claim acceptable?

Yes, for trimBlanksEnd and stripClosingHashes.

• Each is one loop that only walks backward. Linearity follows from reading the code, so a test wouldn't add evidence.
• The equivalence check pins the behavior, and the source pin catches the two exact regressions.
• A timing assertion is what the budget design rightly avoids.

That argument doesn't extend to the block regexes, which is how B1 got through: their linearity was asserted, not argued. After the fix above it can be argued (.*$ always matches on the first try), and a semantic test pins the flag, so I'd accept a probe table there too.

Runs I checked (logs only, nothing rerun)

Mutants. mutants-run-r2.txt has 32 exit 1 lines (v7–v15 plus the 23 from round 1). Each mutant's .out has at least one AssertionError [ERR_ASSERTION], and none shows a timeout, a nonzero cancelled count, ECONNREFUSED or SyntaxError. Controls: 7/7, 8/8, 10/10, 15/15 and 1/1, which matches build.md. The named failing tests for v7–v15 match the table.

Gate. suites-run.txt shows rc=0 for every suite, and the counts match build.md:

• node suites: project 37, bus 314, cli 215, webui 139, business 112, mosaic 69, plugins 28, tasks 97, harness 105, seat 135;
• script suites: auth 15, conductor 17, config 24, discord 78, extension-package 18, foundation 44, land-work 86, queue 28, release 14, task 98;
• gate-exit 0.

Slot record. It reports the pre-grant single-file runs and the discarded first probe honestly. Sage has those.

Round 1 notes

• N1 (1 MiB + 64 KiB envelope read before the proof): carried as a note, not changed. That's acceptable; I'd like it as a follow-up issue so it isn't lost after landing.
• N2: confirmed. serve.mjs:45 body() throws for any non-object JSON before FILE_SAVE_KEYS is read. The pin test can't fail on the base, and build.md says so.
• N3: fixed in the README.

Nits (don't block)

• In markdown-preview.test.mjs, the comment that begins "Round 2 (B1): one scan for a closer must not look past SPAN ... indexOf records" describes the indexOf-width test, but it sits above the blank-run test. Move it down one test.
• The OVERSHOOT = 8 × 2000 comment covers one link attempt. A closerOf that counts a long backtick or opener run charges the whole run, so work can exceed budget + 8×SPAN on inputs the test doesn't use. That's accounting, not cost: the charge still matches what was scanned. A comment saying the bound is per the listed inputs would do.

Dewey, row 148 round 2 review (security reviewer). Candidate manifest 2ed5a097ca2c2b68bfcadee9abe6f91f1b5d1da5aa9041b95636c23860ba91da, base 63c82f1c4. **Verdict: changes.** One finding blocks (B1). It's static analysis: Sage didn't grant me a run, so I haven't run anything. Filbert reached the same finding independently and holds the next slot for a probe of this shape. Filbert's probe table follows on this issue. B1 has been in the code since round 1, and my round 1 review missed it. ## What I checked I applied row148.patch r2 to a worktree at 63c82f1c4: 27 files, +1605 −46, and every manifest line passed `sha256sum -c`. Then I did three things: - read markdown-preview.js in full, plus its round 1 → round 2 diff; - read the test diff; - read build.md (budget, scan audit, mutants, probe table, gate, N1–N3, slot record). **The counter, inline.** These scans charge `work` on a miss, and a hit is consumed because the caller moves to the end of what was scanned: - findRun; - closerOf, including its nested findRun and run counts; - linkAt: label loop, `space()`, destination loop, both findWithin calls and the angle test. A single linkAt can scan past the budget check by at most about 4×SPAN. closerOf stops its nested findRun calls once the budget is spent. Successful scans re-walk at most once per nesting level, and there are at most 12 levels. linkTarget checks the length against SPAN before any regex runs. I found no inline forward scan that escapes the counter. **Past the budget.** linkAt, closerOf and findRun return at once. Every opener then reaches `pending` and a text node. The page still builds block elements (h1–h6, p, ul/ol/li, blockquote, pre/code) whatever the budget, and all of their text arrives through textContent or text nodes. The only attributes the page sets are: - `href`, only through linkTarget; - `rel` and `target`, constants; - `start`, from `String(parseInt(...))`; - className, constants. So output past the budget can't carry markup. The test covers this: it walks the whole tree to {#fragment, p, #text} and finds no a, em, strong, code, img, script or span elements. **trimBlanksEnd and stripClosingHashes.** Both are single loops walking back from the end, so they are linear. Both sides apply `.trim()` before the hash strip, so the order is unchanged. The old regexes split characters into three classes: blank, `#`, and anything else. The equivalence test's alphabet {space, tab, `#`, `a`} covers all three classes up to length 6, which is enough for those patterns. U+2028 and other non-blank whitespace fall in the "anything else" class for both the old and new code. ## B1 (blocks): three block regexes backtrack quadratically on a line that contains U+2028 or U+2029 build.md lists "the block regexes (anchored, once per line)" as uncharged. Being anchored doesn't make them linear. JS `.` doesn't match U+2028 or U+2029. `split('\n')` leaves both characters inside a line. So `(.*)$` can fail inside a line, and these three regexes then backtrack: - **ATX** (markdown-preview.js:22) `^ {0,3}(#{1,6})(?:[ \t]+(.*))?$` on `"#" + " ".repeat(m) + "
"`. `[ \t]+` gives back one blank at a time, and after each one `(.*)` rescans the rest of the blank run before `$` fails at U+2028. That's about m²/2 steps. - **ITEM** (:26) `^( {0,3})([-+*]|\d{1,9}[.)])([ \t]+|$)(.*)$` on `"-" + " ".repeat(m) + "
"`, or `1.` and the same. It has the same O(m²) shape. - **FENCE** (:21) `^( {0,3})(`{3,}|~{3,})(.*)$` on r backticks (or tildes), L other characters, then U+2028. Each backtick given back makes `(.*)` rescan the L characters. That's O(r·L), quadratic when both are about m/2. The work counter doesn't see any of these. ATX and FENCE run through `starts()` for every line at every nesting level, and ITEM runs on every line that could open a list. Round 2's probe table doesn't contain these shapes, as its descriptions read. The rows "fence line with U+2028 after a long tail" and "list item with U+2028 after a long tail" have a short marker and blank run, so their backtracking is linear. The `# a` + blanks rows have no U+2028 after the blanks, so ATX matches on the first try. My step estimates above are inferred from V8 irregexp being a backtracking engine with no memoization; nobody has measured them yet. For scale, a probe-table row went from 30 s at 256 KiB to over 90 s at 1 MiB. That row was the `/[ \t]+$/` case round 2 fixed, which has the same m²/2 shape. Fix: - Give FENCE, ATX and ITEM the `s` flag, or write `([^]*)` for `(.*)`. `.*$` then matches to the end on the first try, and no other part of these patterns backtracks more than linearly. - This changes behavior: a line with U+2028 can then be a heading, item or fence, the same as any other character in a line. That's consistent with splitting lines only on `\n`. - Add a test that needs no clock. Today `# a
b` renders `<p>`; after the fix it should render `<h1>` with text `a
b`. Do the same for `- a
b` → `<li>` and for a fence opener line with U+2028 in its info string. Each of these fails on the current code and fails again if a flag is removed. - One mutant per regex (3): remove the flag. - Extend the probe table with the three shapes at 256 KiB and 1 MiB, for the speed claim. - build.md's "Not charged" line should then state why each block regex is linear, not just that it's anchored. ## The blank-run question: is a probe-only speed claim acceptable?

Each mutant's `.out` has at least one `AssertionError [ERR_ASSERTION]`, and none shows a timeout, a nonzero cancelled count, ECONNREFUSED or SyntaxError. Controls: 7/7, 8/8, 10/10, 15/15 and 1/1, which matches build.md. The named failing tests for v7–v15 match the table. **Gate.** suites-run.txt shows rc=0 for every suite, and the counts match build.md: - node suites: project 37, bus 314, cli 215, webui 139, business 112, mosaic 69, plugins 28, tasks 97, harness 105, seat 135; - script suites: auth 15, conductor 17, config 24, discord 78, extension-package 18, foundation 44, land-work 86, queue 28, release 14, task 98; - `gate-exit 0`. **Slot record.** It reports the pre-grant single-file runs and the discarded first probe honestly.

Filbert review, row 148 round 2: changes.

Candidate manifest sha256 2ed5a097ca2c2b68bfcadee9abe6f91f1b5d1da5aa9041b95636c23860ba91da (agents/researcher/work/queue-148/candidate-manifest.sha256), base 63c82f1c4, request 28807.

Rebuild: applied row148.patch at 63c82f1c4 in my own worktree. The manifest matches, git diff --cached --check is clean, and added lines have no dashes, curly quotes or control characters (27 files, +1605 -46). No drift on the manifest paths from 63c82f1c4 to HEAD. The candidate's public diff sha256 is c2befc64026ff88370483d476967384a1d6abe8d72eca8b62168e8673522b191, equal to public-diff.patch.

B1 (blocking): three block regexes are quadratic on one line, and the work budget doesn't see them

markdown-preview.js is new in this row. Three of its block regexes put a greedy run before (.*)$:

• line 21: FENCE = /^( {0,3})(`{3,}|~{3,})(.*)$/
• line 22: ATX = /^ {0,3}(#{1,6})(?:[ \t]+(.*))?$/
• line 26: ITEM = /^( {0,3})([-+*]|\d{1,9}[.)])([ \t]+|$)(.*)$/

Without the s flag, . matches neither U+2028 nor U+2029, and text.split('\n') keeps both inside the line. On a line made of the marker, a long run of blanks (or backticks for FENCE), then U+2028 or U+2029, (.*) stops at the separator and $ fails. The engine then gives back one character of the run and rescans (.*) to the separator, once per character of the run. Dewey found the same three regexes by reading the code and pointed out the U+2029 case (dewey-0566). I ran the probe.

Probe: one render() of one line, made in node from my verified rebuild. The script is agents/filbert/work/queue-148/r2/probe.mjs. One process per cell, timeout 20 s, none timed out. It ran 2026-10-16T20:46:57Z to 20:47:16Z on Sage's slot (sage-0602). The line is the marker plus N KiB of the run, then the tail named in the second column. work is the meter's count after the render.

FENCE backticks	U+2029	35.6 ms	140.0 ms	554.9 ms	2246.1 ms	1

Each doubling multiplies the time by about 4 with a separator and leaves the control flat, so the cost is quadratic in the run. The meter reads 0 or 1 on every row, so the per-render budget doesn't bound this. I didn't run 1 MiB. At x4 per doubling, the 64 KiB figure extrapolates to roughly 9 to 10 minutes for a single 1 MiB line. That's an extrapolation, not a measurement.

Why the round 2 probe missed it: probe-table.md's "fence line with U+2028 after a long tail" and "list item with U+2028 after a long tail" put text between the marker and the separator, so the greedy run in front of (.*) is short. build.md line 120 lists FENCE, ATX and ITEM as "no: anchored, run once per line", and line 238 says those shapes "were already linear". Being anchored doesn't prevent backtracking inside one line.

A possible fix, the author's choice: the s flag on the three regexes (then (.*)$ matches at the first try), or ([^]*) in place of (.*), or splitting on U+2028/U+2029 as well. A test is needed. The meter can't see regex time, so either a test that renders a long line of each shape with each separator inside a generous bound, or a source pin like v14 and v15, plus the rows above in probe-table.md. SETEXT, HR, QUOTE and the closing-fence check /^(`+|~+)[ \t]*$/ have no greedy run before a ., and I don't count them here.

Not reviewed this round

The blocker sends the row back, so I stopped there. I read markdown-preview.js in full and build.md. I did not finish markdown-preview.test.mjs, the serve.mjs wording or the README NUL change, and I'll review them on the next manifest. I ran no test files. The only run was the probe above.

Filbert review, row 148 round 2: **changes**. Candidate manifest sha256 2ed5a097ca2c2b68bfcadee9abe6f91f1b5d1da5aa9041b95636c23860ba91da (agents/researcher/work/queue-148/candidate-manifest.sha256), base 63c82f1c4, request 28807. Rebuild: applied row148.patch at 63c82f1c4 in my own worktree. The manifest matches, `git diff --cached --check` is clean, and added lines have no dashes, curly quotes or control characters (27 files, +1605 -46). No drift on the manifest paths from 63c82f1c4 to HEAD. The candidate's public diff sha256 is c2befc64026ff88370483d476967384a1d6abe8d72eca8b62168e8673522b191, equal to public-diff.patch. ## B1 (blocking): three block regexes are quadratic on one line, and the work budget doesn't see them markdown-preview.js is new in this row. Three of its block regexes put a greedy run before `(.*)$`: - line 21: `` FENCE = /^( {0,3})(`{3,}|~{3,})(.*)$/ `` - line 22: `ATX = /^ {0,3}(#{1,6})(?:[ \t]+(.*))?$/` - line 26: `ITEM = /^( {0,3})([-+*]|\d{1,9}[.)])([ \t]+|$)(.*)$/` Without the `s` flag, `.` matches neither U+2028 nor U+2029, and `text.split('\n')` keeps both inside the line. On a line made of the marker, a long run of blanks (or backticks for FENCE), then U+2028 or U+2029, `(.*)` stops at the separator and `$` fails. The engine then gives back one character of the run and rescans `(.*)` to the separator, once per character of the run. Dewey found the same three regexes by reading the code and pointed out the U+2029 case (dewey-0566). I ran the probe. Probe: one `render()` of one line, made in node from my verified rebuild. The script is agents/filbert/work/queue-148/r2/probe.mjs. One process per cell, timeout 20 s, none timed out. It ran 2026-10-16T20:46:57Z to 20:47:16Z on Sage's slot (sage-0602). The line is the marker plus N KiB of the run, then the tail named in the second column. `work` is the meter's count after the render. | shape | tail | 8 KiB | 16 KiB | 32 KiB | 64 KiB | work | |---|---|---|---|---|---|---| | ITEM `-` + spaces | `x` (control) | 0.9 ms | 1.0 ms | 1.2 ms | 1.5 ms | 0 | | ITEM `-` + spaces | U+2028 | 41.9 ms | 169.6 ms | 615.8 ms | 2369.6 ms | 0 | | ITEM `-` + spaces | U+2029 | 36.5 ms | 143.5 ms | 568.9 ms | 2221.6 ms | 0 | | ATX `#` + spaces | `x` (control) | 0.6 ms | 0.6 ms | 0.6 ms | 0.6 ms | 0 | | ATX `#` + spaces | U+2028 | 35.7 ms | 141.9 ms | 568.4 ms | 2254.7 ms | 0 | | ATX `#` + spaces | U+2029 | 37.3 ms | 139.2 ms | 555.3 ms | 2253.9 ms | 0 | | FENCE backticks | `x` (control) | 0.4 ms | 0.4 ms | 0.4 ms | 0.4 ms | 0 | | FENCE backticks | U+2028 | 37.3 ms | 139.2 ms | 560.0 ms | 2241.5 ms | 1 | | FENCE backticks | U+2029 | 35.6 ms | 140.0 ms | 554.9 ms | 2246.1 ms | 1 | Each doubling multiplies the time by about 4 with a separator and leaves the control flat, so the cost is quadratic in the run.

Dewey, row 148 round 3 review (security reviewer). Candidate manifest 95ae4736227d1214516c1b3a158082a7ea54ea50572ba579a5636406c466c08f, base 18aee8fa1.

Verdict: approve. My round 2 finding is fixed and tested, and each fix has a mutant that kills it. The HR regex that overflowed the stack is replaced by a linear walk that accepts the same lines. I found nothing new that blocks. I ran two single test files (below), and no probe, mutant or gate run. The rest is a static read plus a check of the Researcher's logs.

What I checked

• row148.patch sha256 1b63164b…, public-diff.patch 8360122b… and the manifest 95ae4736… all match the note. I applied the patch to a worktree at 18aee8fa1, and sha256sum -c passed on all 27 lines. The public diff I generated from that worktree hashes to 8360122b….
• No base drift: git diff 18aee8fa1 862af3079 on the 27 manifest paths is empty.

Round 2 finding (U+2028/U+2029 in FENCE, ATX and ITEM).

• FENCE, ATX and ITEM now carry the s flag, so (.*) runs to the end of the line on its first try and $ matches. It no longer fails and retries from each offset behind a long run.
• SETEXT and the closing fence use disjoint classes before [ \t]*$, so they were already linear.
• The separators test checks a heading, a bullet, a numbered item, and both fence kinds with each separator, plus the slow shape (marker, long run, separator). It is semantic, not timed. Without the flag, the line falls to a paragraph and the test fails. v16, v17 and v18 each remove one flag, and each fails exactly that test.

isRule in place of the HR regex.

• It allows up to 3 leading spaces, then one of - * _, then only that mark plus space or tab, with at least 3 marks. That is the accept set of /^ {0,3}([-*_])(?:[ \t]*\1){2,}[ \t]*$/.
  • blank is space or tab only (markdown-preview.js:50).
  • Leading tabs are already spaces by the split at :332.
  • $ without the m flag matches only at the end of the input, so a separator is a non-mark for both forms.
• It is one pass with no recursion, so the 2 MiB RangeError is gone.
• All four call sites are !isRule(x) && itemAt(x, …), and ITEM's ^( {0,3}) refuses a 4th space anyway. So v21 (a 4th space) is equivalent, as the note says, and keeping the check costs nothing.
• Tests:
  • The exhaustive oracle compares against the old regex on every line up to length 6 over space, tab, -, *, _ and a letter. It asserts more than 5000 lines and more than 100 breaks.
  • The 4 MiB test covers 9 spacings × 2 leads, plus two lines that are not breaks. v25 puts the regex back and fails it at :312.
  • v19, v20, v22, v23 and v24 each fail the list test and the oracle test.
• r3/stack-audit.md: 53 runs at 4 MiB over every regex in the module, all "returns", and 0 literals left out. The removed regex fails 5 of 5 control shapes.

The paintDoc guard and the submit finally (bus.js).

• The render is in try/catch. The fallback is set through textContent, and the Save, status and commit lines still run after a throw.
• The input path and the first async paint both go through paintDoc.
• In the submit handler, everything after s.saving = true is inside try { … } finally { s.saving = false; }. A throw in the first paint happens before the fetch, so nothing is sent, and Save and Reload aren't wedged.
• docs-browser.test.mjs:
  • covers a throwing render (fallback text, no children, draft kept, a save still goes through, Reload works, no rejection);
  • covers a status setter that throws mid-save (one rejection, no POST, Save enabled after the next input, a 4th read on Reload);
  • covers ?throwrender on the first paint.
• e6 (the catch removed) fails at :174, and e7 (the reset moved out of the finally) fails at :202. The patch lines match the candidate source at bus.js:689-692 and :718.

serve.mjs and the README.

• The stale-base message tells the user to reload and edit again, and the generic refusal names the bus code. w4 kills the stale-base wording.
• The README says a file with a NUL never opens because the project read refuses it (project-read-content). That matches packages/project/src/read.mjs:14.

Decision 123. The public diff (+445 −6) adds none of innerHTML, outerHTML, insertAdjacentHTML, document.write, eval, new Function, DOMParser, createContextualFragment or srcdoc. I checked the added lines myself.

The Researcher's runs. I checked r4/mutants.txt, r4/mutants/ and r4/gate.log against build.md "Round 4":

• The 5 controls pass.
• There are 44 mutants (p1-5, b1-2, w1-5, v1-25, e1-7). 43 exit 1, and v21 is the only one that exits 0.
• The gate is rc=0, 21:51:55Z to 21:55:35Z, with the same suite counts as build.md: project 37, bus 325, cli 228, webui 143, business 112, mosaic 69, plugins 28, tasks 97, harness 108, seat 150.

My runs (single files in my worktree, 22:03:22Z to 22:03:31Z): markdown-preview.test.mjs 19/19 and docs-browser.test.mjs 1/1, both rc 0. No processes were left with a cwd in my scratch.

Notes (none block)

1. After a paint throw on a line other than the render, during a save, Save stays off and the status isn't announced until the next input. The test asserts that behavior. Only the test can cause it: the render, the one line that can realistically throw, is caught.
2. s.raw.includes('\0') in bus.js:671 and :698 can't be true, because the read refuses a NUL first. It's disclosed in build.md and harmless as a second check.
3. My N1 stays open as #1650.

Filbert review, row 148 round 3: approve.

Candidate manifest 95ae4736227d1214516c1b3a158082a7ea54ea50572ba579a5636406c466c08f (packet agents/researcher/work/queue-148/, request 28830, note 28831).

Rebuild (run by me)

• Detached worktree at base 18aee8fa1, with git apply --index of the packet patch. sha256sum -c passed against the manifest and git diff --cached --check is clean. The patch touches 27 files, +1749 -46, and the paths match changed-paths.txt.
• No en or em dash or curly quote on any added line.
• No drift: git diff --name-only 18aee8fa1 862af3079 on the 27 manifest paths is empty.
• The round 2 patch is not in the packet any more, so I reviewed the changed files in full, not as an interdiff.

Round 2 finding: fixed

• FENCE, ATX and ITEM now carry the s flag (markdown-preview.js:24, :25, :42). The closing (.*)$ matches through U+2028 and U+2029, so the greedy run before it never has to give back characters.
• isRule (markdown-preview.js:30) replaces the thematic-break regex with one pass over the line. It allows up to three leading spaces, then one mark, then only that mark or blanks, and needs at least three marks. That is the old accept set. The test at markdown-preview.test.mjs:291 checks this exhaustively against the old regex.
• The surviving mutant v21 (a fourth leading space) is equivalent: ITEM's ^( {0,3}) already refuses that line, so nothing changes downstream.

Probe (run by me, on Sage's slot, 22:12:43Z to 22:12:44Z)

40 cells, one process each, timeout 20, all rc 0. Each cell rendered one line through render() of the rebuilt module.

• ITEM, ATX, FENCE: marker + 8, 16, 32 or 64 KiB run + U+2028, U+2029 or a letter control. The slowest cell was 2.2 ms (ITEM letter at 64 KiB). Round 2 took 2.25 s at 64 KiB with a separator.
• isRule: "-" x N took 72 ms at 1 MiB and 251 ms at 4 MiB; "- " x N/2 took 71 and 266 ms, so the cost is linear.

Tests (run by me, singly)

• markdown-preview.test.mjs: 19/19 pass.
• docs-browser.test.mjs: 1/1 pass.

The other new pieces

• The paintDoc guard (bus.js:692): if render throws or the preview script is missing, the page shows a fallback line and the draft is kept. The finally at bus.js:718 resets s.saving. docs-browser.test.mjs covers a throwing render while typing, a status setter that throws mid-save (lines 193 to 207) and a first paint under ?throwrender (line 242).
  • Observation, not a finding: after a mid-save paint throw, the Save button stays disabled in the DOM until the next input repaints, because the paint that would turn it back on is skipped. The test pins this on purpose (one rejection, then typing turns Save back on). It needs a throwing DOM setter to happen, so I'm not asking for a change.
• serve.mjs:
  • The POST route checks the user header, the exact Origin and same-origin Fetch Metadata.
  • It takes a 1 MiB JSON body with exactly the four string keys.
  • The project and path are quoted and cut to 200 characters in the log, and the content is never logged.
  • An unclear outcome is sent:"unknown", and an answer without a commit or for the wrong path is treated as unknown.
  • /api/config edit uses the same test as the route.
• README NUL change: correct. packages/project/src/read.mjs:14 refuses a NUL with project-read-content, and writeHumanFile refuses NUL content before writing.

Not run by me

The full gate, Researcher's mutant set (43 of 44 killed), the criterion runs and the stack audit come from Researcher's receipts in build.md.

Verdict: approve, no findings.

Landed and pushed as d4ea7e5a6 on refactor (a4779d2a5..d4ea7e5a6). Row 148 is done (queue rev 1624).

• Candidate: Researcher's round 3, row148.patch 1b63164b, manifest 95ae4736, 27 paths, base 18aee8fa1. No base drift on the patch paths through a4779d2a5.
• Approvals: Dewey 28832, Filbert 28835 (no findings).
• Decision 123: Mos's go on public diff 8360122b (mos-0636).
• Sage's landing gate on a4779d2a5 plus the candidate: 25 steps, all rc 0 (15 packages, 10 script suites), 22:19:24Z to 22:24:09Z.
• Follow-ups in Vikunja P19: 318 (Save stays off after a paint throw outside the render), 319 (dead NUL check in bus.js:671 and :698), 320 (tracks #1650, the 1 MiB + 64 KiB buffer before the human proof).

Not live yet. The live stack runs 52f35e7a0; the editor reaches the Console only with a re-pin, which needs Mos's go.
