The defect

A lane can hold more ids than one workflow/state read serves: heldLimit is capped at 200 (HELD_LIMIT, plugins/workflow/client.js base :1436, MAX_HELD_LIMIT in service.js). With 250 held, the folded stage control read Show 230 more held tasks — computed from heldTaskCount - heldShown.length alone (base :605) — while pressing it drew 200 rows and became Show less. Ids 201-250 were named and then dropped: the dead line #2256 had just replaced came back as a button that cannot deliver what it promises, and nothing on screen said a remainder existed.

Red first, on live main 4a9d3edd

Clean tree at 4a9d3edd2dcac112797e1d028b3f5f790a4f467e with only plugins/workflow/test/client.test.js carrying the new case (base sources):

• plugins/workflow/test/client.test.js run on its own → 167 tests / 166 pass / 1 fail (the whole plugins/workflow package is 411 / 410 / 1; the table further down quotes that package count)
  • not ok 167 - #2260: the held more-count promises only what the wider page reaches, and the cap is named — the folded count is what the wider page reaches past these 20 rows, not the 230 the lane holds: expected: 'Show 180 more held tasks', actual: 'Show 230 more held tasks'; in the whole-package run the same red is not ok 215.
• The fixture holds 250 ids and serves them the way the host does: workflow/state answers the 20-id page by default and Math.min(heldLimit, 200) when asked, with heldTaskCount: 250. It folds, unfolds and folds again, and checks the count row, the 200 rows the wider page returns, and the line that has to name the cap.

The fix

plugins/workflow/client.js at the tip:

// #2260: the wider read stops at HELD_LIMIT, so a count taken from heldTaskCount alone
// promised ids the next click could not reach. The folded control counts what it reaches.
const heldTotal = workflow.heldTaskCount ?? held.length
const heldRest = Math.min(heldTotal - heldShown.length, HELD_LIMIT - heldShown.length)

• The folded control's count is heldRest (:614), so 250 held under a 200 cap reads Show 180 more held tasks — 20 rows drawn, 180 still reachable.
• A list unfolded with heldTaskCount still above what the host returned draws one wf-held-note line Showing {shown} of {count} held tasks (:607–:609), the shape feedback.js uses for a truncated window; it folds away with the rows it describes.
• HELD_LIMIT (:1445), the heldLimit: 200 wide read, the data-more="held" control, aria-expanded, Show less, the rows and their Re-match action are untouched. With 200 held ids or fewer the Stage text is byte-identical: the #2256 case that pins the 23-id block still reads Show 3 more held tasks, and both #2257 cases are unchanged.

Delta, file by file

file	+/-	kind
plugins/workflow/client.js	+12/−2	written (two computed values, the note row and its CSS rule, one ZH entry)
plugins/workflow/test/client.test.js	+59	written (one new case)
docs/subsystems/workflow.md	+2/−2	written (the held-page clause and the real heldLimit rule)
changelog.d/2260-held-cap-remainder.fixed.md	+1	written (new)
total	+74/−4	4 files, no generated file

plugins/ carries no generated bundle, so nothing here is produced by npm run build or ds-bot-patches generate; patches/ds-bot/** and core/client.js are untouched, and the run below left patches/ byte-identical.

The docs change is the second half of the issue: heldLimitOf reads the value through Number() and keeps it when it is a positive integer, so '10' reads 10 ids and true reads 1, while 0, -5, 3.5, 'many' and null fall back to 20. The page said "any other value falls back to 20"; it now states the real rule, and the code is not tightened.

What I ran at local 7aa88d4b0a7514af7baa198cdd75c6f2594cfcf2 (pushed as 9f8e6e936621d69c830c1d6f0c5fdbf072c6fe5e)

Tier, by path (not by a label)

createGate(risk-rules).judge(files) over exactly these four paths, from 4a9d3edd's .github/agent/risk-rules.json:

risk-tier: T2; basis: plugins/workflow/client.js=T2, plugins/workflow/test/client.test.js=T2, changelog.d/2260-held-cap-remainder.fixed.md=T1, docs/subsystems/workflow.md=T0

78 changed lines in 4 files, no generated file.

Not run

• The smoke bench (dev/bench.sh smoke): this box has no deepseek-harness checkout for it, so it cannot start. core/index.js and core/src/host/ are untouched by this change.
• No browser was available, so the folded and unfolded states are exercised through the module test rather than by clicking.
• The probe the issue quotes (probes/workflow-held-cap.mjs) is not part of this branch; the module test above drives the same 250-id / 200-cap shape through the real Section render.

@Birfy — please review this tip: 9f8e6e936621d69c830c1d6f0c5fdbf072c6fe5e.

Coordinates: head 9f8e6e936621d69c830c1d6f0c5fdbf072c6fe5e · tree b4ca6c0f4c790efc4a5b08c3c5730128c681b4dc · base 4a9d3edd2dcac112797e1d028b3f5f790a4f467e (single parent) · branch dev/4-p470-held-cap-remainder · 4 files +74/−4 · maintainer_can_modify: true · draft: false · tier T2.

The change: the workflow task board's "N more" control on the held list promised tasks beyond the read cap (it said "Show 230 more held tasks" with 250 held and a 200-row ceiling), so clicking it could never reveal them. The remainder count is now clamped to what the wider page actually reaches and the cap is named.

Readings at this tip: red-first single file 167/166/1 (not ok 167, expected Show 180 more held tasks, actual Show 230 more held tasks; whole package not ok 215, 411/410/1) → fixed 167/167/0 and package 411/411/0; npm run verify exit 0, 4590/4590/0 across eight suites; tier computed live from the risk rules on the four changed paths.

Verdict: PASS at 9f8e6e9
Written-by: Reviewer
Attestation: 9f8e6e9 role=Reviewer

Ran at this tip:

$ cd plugins/workflow && node --import ./test/resolve.mjs --test "test/*.test.js"
# tests 411  # pass 411  # fail 0
$ cp base/plugins/workflow/client.js over the tip client.js, same command on test/client.test.js
# tests 167  # pass 166  # fail 1

Red first holds: with only plugins/workflow/client.js reverted to base 4a9d3edd, the one red is the new case, not ok 167 - #2260: the held more-count promises only what the wider page reaches, and the cap is named — expected Show 180 more held tasks, actual Show 230 more held tasks. No other case collapses: the #2256/#2257/#2258 paging cases (20-row fold, wider page, last-page stop) and the Assign cases stay green on the base blob, so the fix does not ride on them turning over.

• Scope matches the claim: 4 files, plugins/workflow/client.js +12/−2, plugins/workflow/test/client.test.js +59, docs/subsystems/workflow.md +2/−2, changelog.d/2260-held-cap-remainder.fixed.md. core/client.js, patches/ds-bot/** and the gate workflows are untouched in the tree diff against base.
• Behaviour: heldRest = min(heldTaskCount - shown, HELD_LIMIT - shown) counts only what the 200-id wide read actually reaches, and the unfolded list past the cap states Showing {shown} of {count}. The cap, the heldLimit: 200 wide read, data-more="held", aria-expanded and Show less are unchanged; at or under 200 held the folded text is byte-identical to base.
• Check-runs at this tip: 14 checks, all terminal; only enqueue-guard is red, which is the expected not-enqueued state. tests-ok, plugins (workflow), package, reviewed tip, risk tier, merge-gate and judge are all success.
