feat(community): configurable page sorts via settings.pages (#73) by Rinse12 · Pull Request #346 · pkcprotocol/pkc-js

Rinse12 · 2026-09-06T10:12:23Z

Implements #73 as designed in the issue body (single PR). Operators choose which page sorts a community generates and which of them embed in the record, and can install sorts as files or packages. Closes #73.

What changed

Config. settings.pages = { posts?: Entry[], replies?: Entry[] }, Entry = { name | path, options?: Record<string, string>, preloaded?: boolean, privateOptions?: string[] }, mirroring settings.challenges. Options are strings only. Unset lists generate exactly today's sorts (hot / best preloaded). posts: [] and replies: [] are legal. Reserved options maxAge ("7d", "1M" = 2629746s so topMonth is unchanged), pinnedFirst and the five exclude* flags are ordinary options on every entry and are passed through to the file.

Registry and built-ins. PKC.pageSorts (plus a pageSorts PKC option that shadows by name), every built-in as its own file under src/runtime/node/community/page-sorts/pkc-js-page-sorts/. active moves out of db-handler.ts and scores through the facade; queryPostsWithActiveScore stays as a thin wrapper for its callers. controversial is a real opt-in built-in; top takes a generic maxAge; SortProps.timeframe retires from the generic path.

Page sort files. { sortName, description?, optionInputs?, scope?, flat?, defaultOptions?, filter?, scoreAll, validatePageSortSettings? }, factory invoked once per start and per settings edit with { pageSortSettings, db }. scoreAll is a whole-set scorer over the survivors, sync. db is a read-only sqlite facade: a second readonly: true connection for file-backed communities, the shared handle plus Statement.readonly for :memory:; both reject writes with ERR_PAGE_SORT_DB_WRITE_REJECTED. db.exclusionClauses(options, aliases) is the single definition of the exclude* flags in SQL.

Generation. The generator runs from the resolved config. Preloaded sorts share the preload budget equally and degrade to pageCids per sort when their first chunk does not fit; the single-chunk shortcut stays (nothing else is generated when every preloaded sort fits, none preloaded means pages: {} with every sort in pageCids); pages keys follow the configured order so the first key is the client default; flat sorts are generated for post replies only. A throwing sort is skipped and reported on the community's error event (ERR_PAGE_SORT_FAILED_TO_GENERATE) on every cycle that generates pages; a changed set of generated post sort keys is logged.

Regeneration. Any change to settings.pages flags every CommentUpdate for regeneration. Windowed reply sorts get a boundary-crossing arm in queryCommentsToBeUpdated (one per distinct window, flagging a parent only when a non-pinned reply was inside the window at the parent's last generation and is outside now), not a heartbeat; the default config adds nothing to the query.

Wire. New optional community.pageSorts?: { posts?, replies? } keyed by sortName with { name?, description?, publicOptions? }; every option the owner set is public unless listed in privateOptions. Present exactly when settings.pages is set. The record schema is loose on the read side so older clients ignore it. RPC settings now list the server's page sorts (minus functions) and RpcLocalCommunity.edit rejects an unregistered name before the round trip.

Behaviour changes to be aware of

An over-budget preloaded posts chunk used to throw ERR_PAGE_GENERATED_IS_OVER_EXPECTED_SIZE and fail the publish cycle; it now drops that sort to pageCids (pages: {}), which is already a valid state. The existing edgecase test was updated accordingly.
pageCids / pages key order is the configured order instead of IPFS-add completion order.
The CID-ref reply storage hardcoded $.best.commentCids in the nested tree reconstruction (twice) and in stale_replies; all three now follow every preloaded sort. A child listed under two preloaded sorts is deduped.
Validation failures are aggregated under ERR_PAGE_SORT_SETTINGS_VALIDATION_FAILED_FOR_PAGE_SORTS with one failures[] entry each, same shape as challenges; on start, invalid entries are reported and skipped so the community still publishes.

Before merge: rebump DB_VERSION to 43. PR #294 merges first and takes v42 (_migrateOldSettings splits exclude.address into publicKeys/names and renames exclude.role to roles). This branch also claims v42 for the wireReplies column, the update-cycle indexes and the derived pseudonymityAliases.originalAuthorSignerAddress, so after rebasing on master it must set DB_VERSION: 43, rename test/node/community/v41-to-v42.migration.db.community.test.ts to v42-to-v43... and seed that test with a v42 schema, and any < 42 migration guard here becomes < 43.

The page-sort settings themselves need no schema change: they round-trip as JSON.

Tests

Written first and run red against unmodified src/ (40 type errors on the not-yet-existing API), then green:

test/node/community/page-sorts/generation.page-sorts.community.test.ts (12): unset config keeps today's nine post and five reply sorts, the 5chan-shaped config generates one of each, keyword no-bump ordering (keyword reply does not bump, prose mention does, a grandchild of a no-bump reply does), no entry preloaded, shared budget with per-sort degradation, none fitting, configured key order, maxAge on new, pinnedFirst both ways, flat ignored at depth 1, a throwing sort skipped with failedSorts, nested trees rebuilt for a non-best preloaded sort plus stale_replies re-flagging.
test/node/community/page-sorts/settings.page-sorts.community.test.ts (16): schema and file validation, empty lists, regenerate-all on any settings.pages edit (and not on an unrelated one), the windowed reply boundary crossing (crossing reply flags, already-out and pinned do not, page drops the aged-out reply), the facade on file-backed and in-memory DBs, community.pageSorts published with privateOptions withheld, no field when unset, the per-cycle error event for a throwing preloaded sort across two publishes.
test/node/pkc/pkc-settings-page-sorts-rpc.test.ts (3): registry serialized over RPC, client-side unknown-name rejection, aggregated edit failure intact over RPC.
Fixtures: test/fixtures/page-sorts/active-no-bump-keyword.js (the generic keyword no-bump sort, nothing named sage inside it; the reference @pkcprotocol/active-page-sort starts from) and throwing.js.

Regression runs locally with local-kubo-rpc: page-generation, nested-reply-signature, modqueue approved/rejection, commentsToUpdate, resolveRepliesCidRefs, v29/v36 migrations, create/edit/editable/start/gc/db/parsing/stats/export/raw/misc community suites, pages.posts, replies, publishing.update, local-community/*, challenge path/settings, and a sweep of test/node/{community,comment,publications,pkc,pages}. The one failure in the sweep was hanging.pkc.test.ts "Fetch community, update a comment" under the local config, which loads a stale leftover .pkc DB whose post block is no longer in kubo; it fails before any code this PR touches and is unrelated.

Review follow-ups (2026-09-07)

Landed after the first review, every behaviour change test-first:

Browser build: stub registry under src/runtime/browser/community/page-sorts/.
Preloaded flat reply sorts work: the CommentUpdate verifier checks an embedded flat page against the post only (repro in test/node/community/page-sorts/flat-preloaded.page-sorts.community.test.ts).
Comment-set loader errors propagate and abort the cycle instead of publishing an empty board; the single-chunk shortcut requires the embedded pages to hold the whole set whenever another sort would be skipped; the generated-key-set check is gone.
community.pageSorts[].publicOptions is the full merged option set (reserved options included); reserved options cannot be private; the owner's value matches the record.
Two scorers: score (per comment, client-side and community fallback) and scoreAll (SQL, community only); the filter hook is removed. sortPageComments / instantiatePageSortFile are exported for UI libraries, with an integration guide in docs/protocol/page-sorts.md.
RPC settings listing uses a lazy db facade so packages that prepare statements in their closure are listed.
settings.pages edits are atomic: side effects apply after persistence and after an address-change restart.
libp2p-js pages client state is seeded for non-built-in sort names (Pages client state is not seeded for libp2p-js when a community publishes a non-built-in sort name #348).

The test server now hosts a page-sorts community on signers[12] (subForPageSorts), used by test/node-and-browser/pages/client-resort.page-sorts.test.ts; restart the test server after checking out this branch.

Second review round (2026-09-07): one scorer, `requireReplies`, `null` declines

Supersedes the "Two scorers" bullet above; the full decision list is in #73 under "Second review follow-ups".

scoreAll and the whole database facade are removed (SQL access can return later as an additive feature). A file has one score, run by the community and by a client re-sorting a page.
score receives the CommentUpdate with replies stripped. A file declaring requireReplies: true receives its descendants as a flat list of lean PageSortReplyEntry entries: the community loads them with one unfiltered raw-row query per generation shared by every such sort, each applying its own exclusion options in JS; a client passes what it walked or sortPageComments throws ERR_PAGE_SORT_REPLIES_REQUIRED.
score returning null declines the comment from that sort on both sides, pinned included. Ties keep the community's order.
The built-in active is max(timestamp, lastReplyTimestamp), so a client re-sorts by bump order from the page alone; pin.test now checks it like every other sort.
New end-to-end active suite (test/node/pages/active.e2e.page-sorts.test.ts) over every PKC config, including a client-installed reply-dependent package walking newFlat pages. The walk example lives in test/node-and-browser/pages/page-sorts-client-test-util.ts; pkc-js exports no walker.

Cost (`test/benchmarks/page-generation-bench.mjs`)

20k posts with 10 to 100 replies each (1.1M replies in total), post page generation with IPFS stubbed, median of 3. Heap growth is heap used after one generation minus heap used after a forced GC before it: the live reply set plus uncollected garbage, an upper bound on what a sort holds at once.

Code state	`settings.pages`	Median	Heap growth
master	nine default sorts	17.5 s	96 MB
this PR before the round	nine default sorts	9.3 s	182 MB
this PR now	nine default sorts	6.8 s	182 MB
before	`active` only (SQL)	4.0 s	56 MB
now	`active` only (`lastReplyTimestamp`)	1.7 s	61 MB
before	no-bump fixture (SQL `scoreAll`)	9.5 s	59 MB
now, first cut	no-bump (`requireReplies`, full entries through the schema row parser)	125 s	1356 MB
now	no-bump (`requireReplies`, lean raw rows)	15.6 s	963 MB

Two things the numbers say. The default sorts grow the heap more on this branch than on master because every sort's ordered copy of the post set is kept until the IPFS adds run together, where master added per sort. And the requireReplies cost is almost entirely the 1.1M lean reply entries held in memory at once, about 870 bytes each, which is what the doc's "a million-post board should not configure a reply-dependent post sort" warning is about; a 5chan-sized board does not notice it.

Known failures unrelated to this PR: two rejection.modqueue cases on the libp2p-js remote config fail identically on the commit before this round (P2P fetch timeouts in the local environment).

Performance round (2026-09-07, issue #351)

The cost table above was taken on bare posts; production posts embed their preloaded reply trees, and with the replies column seeded that way the branch (and master) crashed at 2k posts with too many SQL variables. Measured again with test/benchmarks/page-generation-bench.mjs, which now seeds nested replies the way production writes them (BENCH_NESTED=0 for bare posts, BENCH_COLD=1 to drop the entry cache before each iteration, BENCH_PIPELINE=1 for the whole publish cycle), kubo stubbed:

Scenario	Before	After
20k bare posts, nine default sorts	7.9 s	0.4 s
2k posts / 110k nested replies, nine sorts (0.8 GB of pages)	crash (`too many SQL variables`)	1.2 s cold, 0.2 s with the entry cache warm
20k posts / 1.1M nested replies, nine sorts (6.7 GB of pages)	crash	60 s inside a 2 GB heap
20k posts / 1.1M nested replies, `active` only	crash	17 s
20k posts / 1.1M nested replies, no-bump `requireReplies` sort	crash	20 s, subtrees streamed, nothing board-sized in memory
Whole cycle, 500 posts / 27k comments (every CommentUpdate, then post pages)	224 s	6 s
Whole cycle, 2k posts / 113k comments	hours (per-comment cost scaled with the board)	27 s (0.22 ms per comment)

Nothing holds a board's replies in memory at once, and nothing about them is persisted beyond the CID refs the DB already kept (details in #351):

Posts are loaded lean; page entries are serialized a batch of posts at a time from one indexed read of their subtrees (queryRepliesUnderPosts), and a page fetches the entries it does not hold when it is built. Serialized entries persist across generations while the CommentUpdate's updatedAt is unchanged, under a byte budget derived from the heap limit, so a steady board re-serializes only the posts that changed. test/node/community/page-generation/nested-posts-pages.page.generation.community.test.ts pins every added page byte for byte to the published CommentUpdates, across a change between two generations, and the flat read to the level walk.
A requireReplies post sort streams the same way: score still gets each post's whole subtree, loaded one batch of posts at a time in scoring order.
Positional row mapper (.raw(true), sorted keys so native JSON.stringify is canonical), exact sync UnixFS size (calculateUnixFsDagSizeCidV0, pinned to the importer at every encoding boundary), one size per entry across sorts, pages joined from entry JSON under a byte budget for the pages in flight.
The reply-scope query no longer runs the recursive CTE, which scanned the board per call (0.8 s per comment at 112k comments); the direct children are read lean and their listed subtrees walked level by level by primary key.
The update cycle: indexes on comments(parentCid, postCid, authorSignerAddress), commentEdits/commentModerations(commentCid) and a derived pseudonymityAliases.originalAuthorSignerAddress (DB v42 today, v43 once rebased on fix(community): bind excludes, roles and address lists to the signer and drop exclude.address #294, see the note at the top; queryCommunityAuthor was a full scan of two tables per comment), a per-connection prepared statement cache, one logger per namespace, Ed25519 signing through WebCrypto (byte-identical). markCommentsAsPublishedToPostUpdates and forceUpdateOnAllCommentsWithCid are batched too: a cycle updating every comment crashed the same way.

Still O(board) per cycle and left for a follow-up: queryCommentsToBeUpdated (1.2 s at 113k comments), and updateCommentsThatNeedToBeUpdated returning every update object of the cycle in memory (1.1 GB at 113k comments), which bounds a full regeneration of a multi-million-comment board. The page-size doubling scheme makes the last page of a 20k nested board several hundred MB, so that board needs more than a 1 GB heap for its last pages. On the 100k-post board with 55 replies each, every publish has to emit about 4.4 GB of pages per configured sort because the nested reply pages are inside the signed CommentUpdate; taking replies out of the CommentUpdate signature is the protocol-level fix.

The test server must be restarted after pulling: the DB version is bumped and its communities are held at v41 until then. test/node/community/local-community/editing.test.ts fails to load on this branch before and after this round (a module cycle when editing.js is imported standalone), unrelated.

Client sorter removed, update cycle batched (2026-09-08, issue #352)

sortPageComments / instantiatePageSortFile are no longer exported and re-sorting is not part of the protocol: a UI installs the package the community names and applies its score itself. docs/protocol/page-sorts.md "Client side" shows that as a code block; the test util carries it as resortPageLikeAUi for the client re-sort and active e2e suites. page-sort-client.ts is page-sort-scoring.ts (generator helpers only); ERR_PAGE_SORT_REPLIES_REQUIRED is gone.
Duplicate sortName across two registry keys, and on createCommunity, both reject (tests added; the edit path already had one).
The bench seeds one author per 25 posts (BENCH_POSTS_PER_AUTHOR) and reports CPU user/system, peak RSS and DB size per run. With that seeding the whole cycle on the 2k-post / 113k-comment board took 440 s: the author aggregate re-summed the author's whole history for every one of their comments. queryCalculatedCommentUpdates now reads every field group in one statement per chunk and memoises the author aggregates per cycle; the cycle runs per depth across the whole board. Same semantics (equivalence test over votes, moderations, edits, aliases, pending, removed, deleted, foreign-address and update-less comments), no schema change.

2k posts / 113k comments / 80 authors, whole cycle, median of 3	Before	After
cycle	440 s	23 s
CPU user + system	504 s	36 s
RSS peak	2.48 GB	2.69 GB
DB file + WAL	239 MB	235 MB

Whole update pipeline with IPFS, and the memory the cycle holds (2026-09-08, issue #355)

The benches above stub the kubo client out, so nothing about the daemon was measurable: the reply-page and posts-page adds, the postUpdates MFS writes, the community record add and the IPNS publish. test/benchmarks/update-pipeline-bench.mjs runs syncIpnsWithDb's body phase by phase against a real daemon and reports, per iteration, the per-phase ms, every kubo method's calls and time (plus a wall-clock "at least one call in flight" figure, since 50 concurrent MFS writes make the summed time exceed the cycle), sampled peak heap and RSS, CPU, bytes added to IPFS, and the heap the cycle still holds when the record goes out. BENCH_STUB_KUBO=1 gives the same board with the old stub, which is how the daemon's share is attributed, and the file detects the code state so it runs unchanged on master.

Where a cycle goes, 300 posts / 16,352 comments, real kubo, median of 3: 3.76 s for the cycle, of which the CommentUpdates are 2.60 s and the record build with the posts pages, MFS writes and IPNS publish 1.07 s; 0.90 s of it is kubo (24%). The same board with the stub is 3.03 s, so the daemon is about 20% of the cycle. Per cycle the board writes 170 MB to IPFS (573 MB at 1,000 posts): every sort serializes the whole board, and page doubling makes single adds several MB. 1,000 files.write calls sum to 45 s of daemon time but 3 s of wall time at the concurrency of 50.

Two seeding fixes came with it, because a published record is schema-parsed and its pages are parsed back afterwards: seeded cids are real CIDv0 strings and the seeded signature.publicKey is a real 32-byte key. Page byte sizes are unchanged. The record's two verifyCommunity calls cannot run on a seeded board (placeholder author signatures) and are stubbed out of the bench; that cost is fixed per cycle and does not grow with the board.

What the cycle held, and what it holds now

The cycle carried every comment's whole CommentUpdate - the inline reply page is the bulk of a row - from the first depth until the record was published, because the array updateCommentsThatNeedToBeUpdated returns was passed all the way to syncPostUpdatesWithIpfs, which needs the posts' rows to write their MFS files and nothing but the cid of every other comment. At 16k comments that array measured 21.6 MB of post rows and 27.1 MB of reply rows, of which nothing is read after the DB upsert.

updateCommentsThatNeedToBeUpdated takes an optional per-slice consumer; a caller that omits it still gets every row, which is what the tests walking small boards want.
syncPostUpdatesWithIpfs is split into writePostUpdatesToMfs (one slice: the purge filter, the writes, the flush and the post-write purge re-check of Purge vs postUpdates sync race: in-flight sync resurrects a purged post's MFS entry #142 / Purge landing during syncPostUpdatesWithIpfs MFS writes resurrects the purged post's postUpdates entry #304) and the whole-cycle wrapper, which keeps its contract for callers holding a cycle's rows.
A depth is calculated in slices of 2,000 - at 500 the phase cost 28% more, at 2,000 it is unchanged - and updateCommentsAndWritePostUpdates writes each slice's posts into MFS and drops the rows, keeping only cids. markCommentsAsPublishedToPostUpdates stays where the whole-cycle sync ran, so a cycle that fails before it leaves every comment flagged for the next one.

1,000 posts / 55,867 comments, real kubo, median of 3	Before	Consumer only	Streaming the MFS writes too
heap held when the record is published	163 MB	99 MB	4 MB
live heap at the end of the cycle	169 MB	104 MB	10 MB
sampled peak heap delta	586 MB	510 MB	406 MB
peak RSS	2,024 MB	1,960 MB	1,856 MB
CPU (user)	20.7 s	21.1 s	20.2 s

Wall time is unchanged; the MFS writes moved from the record phase into the CommentUpdates phase. This closes the "every update object of the cycle in memory (1.1 GB at 113k comments)" item left open by the #351 round above.

Verified at 100k posts, and what it exposed

A board of 100,000 posts with 10-50 replies each - 3,098,259 comments, 2.7 GB of SQLite, 4.5 minutes to seed, kubo stubbed - never finished a cycle: Ineffective mark-compacts near heap limit at 7,927 MB of an 8 GiB cap, RSS climbing 0.5 -> 9.0 GB. The crashed run left its database behind, so the suspected term was measured on that exact board in isolation:

queryCommentsToBeUpdated()  ->  3,098,259 rows
                                339,285 ms (5.7 minutes)
                                2,666 MB of heap held by the rows (902 bytes a row)
                                9,097 MB RSS while holding them (SQLite's CTE working set on top)

So what the cycle carries is now flat, but that is not the only term proportional to the board: the entry to the cycle still is, and it is what a large board hits first. "The cycle's memory no longer grows with the board" is true of the retention across the cycle, not of the query that starts it.

The flag query, and the repin walk it exposed (issue #355)

Both of the items that section used to list are done.

queryCommentsToBeUpdated no longer materializes rows. The flag set is now an integer-keyed temp table, temp.commentsToUpdate (id INTEGER PRIMARY KEY), filled by one INSERT OR IGNORE per arm of the old query, with the author cascade and the parent chain reading the table they extend. The publish cycle reads it as one array of cids per depth and each slice loads its own rows. Every arm's semantics are unchanged and commentsToUpdate.db.community.test.ts covers them.

The plan was fine all along; the shape was not. Every UNION and DISTINCT in the old query deduplicated on a temp B-tree keyed by the whole ~900-byte row, about six stacked levels, each copying the board again. Integer keys are the whole win: the same statement sequence keyed by cid strings took three times as long.

3.1M comments, everything flagged	shell	in JS	heap held by the result
original, `SELECT c.*` through the CTEs	120 s	339 s	2,666 MB
same CTEs, cids only	56 s	62 s	756 MB
one statement per arm, cid-keyed temp table	42 s
the same, rowid-keyed	14.5 s	12 s	219 MB

PRAGMA cache_size at 512 MB, mmap_size at 8 GiB and an index-only formulation of the first arm were all measured and all changed nothing.

With that in place the CommentUpdates phase completed for all 3,098,259 comments in 35 minutes with the heap between 300 and 800 MB throughout, then wrote the 100,000 postUpdates files. Two things surfaced on the way:

repinCommentsIPFSIfNeeded was a second O(board) materialization, on the start path rather than the publish path: it read every comment row into an array and built one promise per comment before the first pin, so the concurrency limit of 50 bounded what was in flight but not what was allocated. It OOMed an 8 GiB heap before the publish loop began, on any board whose kubo repo lost its pins. Filed as fix(community): repinCommentsIPFSIfNeeded loads every comment row into memory on start #359 and fixed here: iterateAllCommentsOrderedByIdAsc pages on rowid and the walk pins a batch at a time. Same board, same process, kubo add stubbed: 33 s with the heap peaking 185 MB above its start and returning to it, where the old whole-table read still dies of OOM.
An import cycle this branch put on the eager path. The page-sort registry imports pages/util for the built-in scoring functions, which reaches base-client-manager -> runtime/node/util -> comment-client-manager -> publication-client-manager -> pkc-client-manager, and that last module extends BaseClientsManager. Importing editing.js, pages/util or the registry on its own threw Class extends value undefined, which is why editing.test.ts failed at import. The node util was in that cycle only to read one numeric constant out of a clients manager; it now comes from constants.js, which imports nothing. The same imports load fine on master, so this was a regression of this branch.

Open questions and TODOs

Ordered by what blocks what. The first two want a decision before anyone writes code.

1. Flat reply sorts still publish `replies` on their entries (this PR's own open question)

test/node/publications/comment/replies/replies.test.ts > flat sorts include nested replies and hide nested replies fields fails on this branch. It asserts that every entry of a flat reply page has no replies; each one carries {pages: {}, pageCids: {...}}.

stripRepliesFromPageComment exists and does exactly what the test wants, but it is only applied to the entry a sort file's score receives, so a file cannot mistake the preloaded slice for the reply set. What gets published is unstripped.

The question is what a flat page's entries should carry. A flat sort already lists every descendant as a top-level entry, so each entry also carrying its own reply page duplicates the subtree and inflates the page, which is the same amplification #312 is about. Against that, dropping replies changes what a client holding one of those entries can do without another fetch. Whichever way it goes, the test encodes one of the two answers and should be made to match the decision rather than deleted.

2. #360: page doubling has no cap

The chunker sizes page n at 2^(n-1) MiB with no upper bound, and each page is built as one JavaScript string. V8 caps a string at 536,870,888 characters, so page 10 at a 512 MiB cap is the last one that can be built and page 11 at 1 GiB is the first that throws RangeError: Invalid string length. That puts the ceiling at about 1 GiB of serialized entries per sort, and the 100k-post board needs roughly twice that: the record phase died there, with the heap climbing from 800 MB to 5.6 GB building the last pages.

This is what now stands between a large board and a completed cycle. #360 has the measured table and three options; the fix is to cap the doubling and keep chunking at the cap, and the open question is the constant. Hops trade against page size as hops = sort bytes / cap: on a 2 GiB sort, 16 MiB is about 128 pages, 32 MiB about 64, 64 MiB about 32. 32 MiB is suggested, which keeps the largest page's build cost near 64 MiB of heap.

3. #361: the flag query still scans the whole board every cycle

Parked as a future TODO, not being worked on. Once every comment has a published CommentUpdate, which is the state a live board is in on every quiet cycle, the query correctly flags nothing and takes 60 seconds to say so at 3.1M comments. Each of its five arms is one join of comments against commentUpdates across the board, 6 to 18 seconds apiece, and that is intrinsic to what the arms are: invariant scans asked of every comment every cycle. Getting under a cycle interval needs dirty-marking at write time with the invariant arms demoted to a periodic repair pass. #361 has the arm-by-arm table and the sketch.

4. Page re-add amplification, unchanged

The whole board is re-serialized and re-added to IPFS for every sort on every cycle: 170 MB at 16k comments, 573 MB at 56k. Related to #312 and the reason the chunks in #360 get large in the first place.

5. The page-generation entry cache is by design

Its budget is heap/8 capped at 512 MB. Noted so it is not mistaken for a leak.

Benchmarks used above, none of them in any CI glob: test/benchmarks/flag-query-bench.mjs <path-to-community-db> times the flag query and the heap its result holds on an existing board, and update-pipeline-bench.mjs runs a whole cycle, reusing a board left by an earlier run with BENCH_COMMUNITY_ADDRESS. The seeded 3.1M-comment board is cached locally and takes about 4.5 minutes to rebuild; it now holds every CommentUpdate, so it measures the steady state as it is.

…ing tests (#73) Fixtures: a generic keyword no-bump active sort loaded via settings.pages[].path (nothing named sage inside it) and a sort whose scoreAll always throws. Generator-level tests drive the page generator against a seeded DB with a fake IPFS client: unset settings.pages keeps today's nine post and five reply sorts, a 5chan-shaped config generates one of each, keyword no-bump ordering, no entry preloaded, shared preload budget with per-sort degradation, configured key order, maxAge on a non-top sort, pinnedFirst, flat sorts ignored below depth 0, a throwing sort skipped, and nested reply trees rebuilt for a non-best preloaded sort. Settings-level tests cover schema and file validation, regeneration of every CommentUpdate on any settings.pages edit, the windowed reply sort boundary crossing arm, the read-only db facade on file-backed and noData communities, the published community.pageSorts field, and the per-cycle error event for a sort that stops producing.

Operators choose which page sorts a community generates and which of them embed in the record, and can install sorts as files or packages. Mirrors settings.challenges: entries are { name | path, options, preloaded, privateOptions }, options are strings, a file returns { sortName, scoreAll, filter?, scope?, flat?, optionInputs?, defaultOptions? }. - Registry PKC.pageSorts with every built-in as its own file under page-sorts/pkc-js-page-sorts; active moves out of db-handler and scores through the read-only sqlite facade (a second readonly connection for file DBs, the shared handle plus Statement.readonly for in-memory ones); controversial is now a real opt-in sort; top gets a generic maxAge and timeframe retires from the generic path. - The page generator runs from the resolved config: preloaded sorts share the budget equally and degrade to pageCids per sort, the single-chunk shortcut stays, pages keys follow configured order, flat sorts are generated for post replies only, a throwing sort is skipped and reported on the error event every cycle. - Any settings.pages edit regenerates every CommentUpdate; windowed reply sorts get a boundary-crossing arm in queryCommentsToBeUpdated instead of a heartbeat; the nested reply reconstruction and stale_replies follow every preloaded sort instead of best. - New wire field community.pageSorts publishes name, description and the public options of each configured sort. - An over-budget preloaded posts chunk now drops to pageCids instead of failing the publish cycle.

…cument settings.pages (#73) - PKC.pageSorts / the pageSorts export mirror PKC.challenges, and the RPC server serializes the registry (minus functions) so a client can render a picker and RpcLocalCommunity.edit rejects an unknown name before the round trip. - docs/protocol/page-sorts.md covers configuration, reserved options, built-ins, community.pageSorts, validation and failure handling, and authoring a sort file; pages.md, README and the docs index point at it. - _pageSorts is initialized so it stays out of the community JSON; the failure reporter tolerates generator mocks without failedSorts.

📝 Walkthrough

Walkthrough

This change adds configurable post and reply page sorts through settings.pages, custom sort registries, validation, generation, publication metadata, RPC discovery, and client-side re-sorting. It also adds batched reply reconstruction, streaming page generation, database indexes, benchmarks, migration coverage, and runtime support changes.

Changes

Configurable page-sort protocol

Layer / File(s)	Summary
Page-sort contracts and transport `src/community/schema.ts`, `src/community/types.ts`, `src/pages/types.ts`, `src/pages/page-sort-options.ts`, `src/errors.ts`, `src/rpc/src/`, `README.md`, `docs/protocol/`	Defines `settings.pages`, page-sort factories, reserved options, `requireReplies`, public metadata, validation errors, RPC serialization, and client discovery rules.
Sort resolution and client execution `src/runtime/node/community/page-sorts/`, `src/pages/page-sort-scoring.ts`, `src/runtime/browser/community/page-sorts/`, `src/pages/util.ts`, `test/node-and-browser/pages/*`	Resolves built-in, registered, and path-based sorts. Validates options and scopes. Applies exclusions, stable scoring, nullable scores, pinned ordering, and reply-dependent scoring.
Page generation and database reconstruction `src/runtime/node/community/page-generator.ts`, `src/runtime/node/community/db-handler.ts`, `src/runtime/node/community/db-row-parser.ts`, `src/runtime/node/community/local-community/*`	Generates configured sorts with shared preload budgets, streaming reply loading, serialized-entry caching, CID-ref reconstruction, batched SQLite access, and per-sort failure handling.
Batched update and publishing pipeline `src/runtime/node/community/local-community/comment-updates.ts`, `src/runtime/node/community/local-community/ipns-publishing.ts`	Processes comment updates by depth and batches, writes post-update files during calculation, publishes updated CIDs, and removes the fixed `hot` generation path.
Validation and compatibility coverage `test/node/community/page-sorts/`, `test/node/community/page-generation/`, `test/node/pkc/`, `test/node/community/v41-to-v42.migration.db.community.test.ts`, `test/node-and-browser/`	Covers configuration validation, atomic edits, generation, preloading, failures, reply sorting, RPC transport, client sorting, migrations, and updated generator APIs.

Estimated code review effort: 5 (Critical) | ~120 minutes

Merge Risk: 🟡 Moderate · up to dd51c

Older database migrations can lose alias lookup data, complete sort failures can omit posts without reporting errors, and some reply-sort configurations can make update cycles unnecessarily expensive. These issues should be resolved before merge.

229-231: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

generatedKeys mixes two different key sets, so the diagnostic misfires.

For the single-chunk shortcut the code reads keys(generatedPosts.singlePreloadedPage), which holds only the preloaded sorts. For the full generation it reads keys(generatedPosts.allPageCids), which holds every generated sort, preloaded and pageCids alike.

If settings.pages.posts configures both preloaded and non-preloaded sorts, the two sets differ. When the community crosses the single-chunk boundary in either direction, for example when one more post exceeds the preload budget, warnIfGeneratedSortKeysChanged logs Generated posts page sort keys changed since the previous cycle even though the configuration did not change. The diagnostic then loses its value for the case it was added for.

Compare the same key set in both branches. The preloaded key set is the one the previous cycle can be compared against.

Consider deduplicating failed-sort reports per update cycle.

calculateNewCommentUpdate runs once per flagged comment, and updateCommentsThatNeedToBeUpdated runs it for every comment in the batch (up to 50 concurrent per depth). If one configured reply sort file throws, every comment in the batch emits its own error event and log line for the same sort. A large batch produces one event per comment instead of one per cycle.

A cycle-scoped collector avoids the duplication. Collect failedSorts into a map keyed by sortName in updateCommentsThatNeedToBeUpdated, then call reportFailedPageSorts once after the batch completes.

Cache reply subtrees by CID. In queryPageCommentsWithResolvedReplies and resolveRepliesCidRefsForEntries, each preloaded sort can call attachReplies for the same child CID. Each call rebuilds that child’s full descendant subtree. Each attachReplies implementation also uses children.find(...) for every CID, which performs repeated linear scans. This can increase reconstruction cost with the number of sorts and descendants. Cache attachReplies results by CID and build a CID-to-child index before the sort loops.

Remove the client-side serverPageSorts gate for page-sort names.

A valid PageSortFileFactory can use the real PageSortDb during construction. RPC metadata invokes it with noDb and omits its name when construction throws. RpcLocalCommunity.edit then raises ERR_RPC_CLIENT_PAGE_SORT_NAME_NOT_AVAILABLE_ON_SERVER before editCommunity reaches the server. The server-side resolver already uses the complete pkc.settings.pageSorts ?? pkcJsPageSorts registry with a real database. Rely on that resolver, or expose a separate complete name-only registry for this check.

Keep the Node-only page-sort registry out of the browser entry point.

The browser build rewrites /runtime/node/ imports to /runtime/browser/. This import therefore becomes ./runtime/browser/community/page-sorts/index.js, but that file does not exist. verify-browser-imports will report a dangling import, and browser consumers of dist/browser/index.js cannot load the package. Export the registry from a Node-only entry or provide a browser-safe registry.

Pre-filter flat-window seeds by the reply-only boundary. Each update pass with a distinct flat window seeds windowed_flat_${i}_ancestors from every non-root reply and walks its ancestors before applying crossingClause. Add r.timestamp < :windowNow - :windowMaxAge${i} to the seed. Keep the lower-bound predicate that uses cu_anc.updatedAt after resolving the depth-0 ancestor. This preserves results and avoids walking replies that cannot cross the window.

🗄️ Data Integrity & Integration | 🟠 Major | ⚡ Quick win

sortComments sorts a shared cached array in place, so one sort changes another sort's tie order.

Line 325 assigns unpinned = comments when sort.pinnedFirst is false. comments is the caller's array, not a copy. If the sort file declares no filter and no maxAgeSeconds, unpinned stays the same array object. Line 346 then calls unpinned.sort(...), which reorders that array in place.

_createCommentLoader caches one array per exclusion key and hands the same array object to every sort that shares the key (Line 381-382). The comment at Line 372-373 states that all sorts share one query unless an owner sets an exclude* option, so sharing is the normal case.

Consequence: after a pinnedFirst: false sort runs, the shared array is left in that sort's order. Array.prototype.sort is stable, so every sort processed later resolves equal scores using the previous sort's ranking instead of the query order. Page contents and page CIDs then depend on the position of a sort in settings.pages, and reordering the list changes published pages for unchanged data.

Trigger: settings.pages.posts with two sorts that share exclusions, the first with pinnedFirst: false, and posts that tie under the second sort's scorer.

🐛 Proposed fix: never sort the loaded array in place

const pinned = sort.pinnedFirst ? comments.filter((entry) => entry.commentUpdate.pinned === true) : []; - let unpinned = sort.pinnedFirst ? comments.filter((entry) => entry.commentUpdate.pinned !== true) : comments; + let unpinned = sort.pinnedFirst ? comments.filter((entry) => entry.commentUpdate.pinned !== true) : [...comments];

Bound waitFor with a deadline.

If the predicate stays false, the helper can keep the test body pending until the Node runner’s 160-second Vitest timeout. That timeout does not cancel the pending promise, so the test’s finally block is not reached and the unsubscribe and post.stop() cleanup are skipped.

…nt-runnable active (#73) Second design review of PR #346. The score contract is now a single per-comment `score`; `scoreAll` and the whole database facade branch are removed (SQL access can return later as an additive feature). - `score({ comment, commentUpdate, options, baseTimestamp, replies? })`: the CommentUpdate arrives with its nested `replies` stripped. A file that sets `requireReplies: true` receives every descendant of the scored comment as a flat list of lean `PageSortReplyEntry` entries; the community loads them with one unfiltered raw-row query per generation shared by every such sort, each applying its own exclusion options in JS, and `sortPageComments` throws ERR_PAGE_SORT_REPLIES_REQUIRED when a client passes none. - `score` returning `null` declines the comment from that sort on both sides, pinned included; ties keep the community's order. - The built-in `active` is `max(timestamp, lastReplyTimestamp)`, so a client re-sorts by bump order from the page alone. - The no-bump fixture is score-only; new fixtures cover declining and a reply-count sort under both scopes. - End-to-end `active` test over every PKC config, client walk-and-re-sort example, pin.test checks `active` like every other sort. - Benchmark script (test/benchmarks/page-generation-bench.mjs): 20k posts with 1.1M replies, default sorts 17.5s on master, 6.8s here; the requireReplies no-bump sort 15.6s against 9.5s for the SQL version it replaces.

Whole cycle for 500 posts / 27k comments: 224 s -> 6.5 s; 20k posts / 1.1M nested replies, nine sorts: crash -> 6.7 s inside a 2 GB heap; 20k bare posts 7.9 s -> 0.7 s. - `commentUpdates.wireReplies` (DB v42): the canonical JSON of the signed wire `replies`, stored when the CommentUpdate is signed. A page entry splices it in verbatim, sorting works on lean rows, and a page fetches the stored replies of its own entries when built; rows without it resolve the CID-ref tree, batched under the SQLite variable cap (also `markCommentsAsPublishedToPostUpdates`, `forceUpdateOnAllCommentsWithCid`, the purge random-comment `NOT IN`). - Positional `.raw(true)` row mapper for the page queries, building every object with sorted keys so native `JSON.stringify` is byte-identical to safe-stable-stringify; exact sync UnixFS CIDv0 DAG size from the byte length; one size per entry across sorts; page strings built by joining entry JSON under a byte budget for the pages in flight, each scoped to its own async frame. - `score` called unwrapped after one validation of the file. - Indexes on comments(parentCid, postCid, authorSignerAddress), commentEdits/commentModerations(commentCid), pseudonymityAliases(originalAuthorSignerAddress) (derived column, backfilled by the migration); a per-connection prepared statement cache for the per-comment update queries; one logger per namespace. - Ed25519 signing through WebCrypto when available (deterministic, byte-identical), noble as fallback. - Benchmark seeds nested replies and wire replies the way production writes them, samples peak heap, and `BENCH_PIPELINE=1` times the whole publish cycle.

failedSorts is dropped when every sort fails.

Line 599 returns undefined when preloaded and nonPreloaded are both empty. failedSorts is discarded on that path. The caller then treats the cycle as "nothing to paginate": reportFailedPageSorts never runs, the stored posts state is cleared, and a record is published without the posts feed. Every configured sort failing is precisely the case that must abort the cycle so the last published feed stays available.

If failedSorts is non-empty and no sort produced chunks, throw instead of returning undefined.

Add a visited set to the descendant traversal.

Move the v42 alias backfill after the v38→v39 column rename.

_copyTable runs the new v42 block before the existing v39 rename block at Lines 863-872. A database at version < 39 stores the key in originalAuthorSignerPublicKey, not originalAuthorPublicKey. The typeof srcRecord["originalAuthorPublicKey"] === "string" guard therefore fails for every alias row in such a database, and originalAuthorSignerAddress stays null.

queryCommunityAuthor then finds no alias rows through the indexed reverse lookup at Lines 2900-2908, so an author's alias comments no longer contribute to their karma after a pre-v39 migration.

🐛 Proposed fix: derive the address after the rename

- // The alias reverse-lookup column (v41 → v42, issue `#351`) - if ( - currentDbVersion < 42 && - srcTable === TABLES.PSEUDONYMITY_ALIASES && - typeof srcRecord["originalAuthorPublicKey"] === "string" - ) - srcRecord["originalAuthorSignerAddress"] = deriveAliasOriginalAuthorSignerAddress(srcRecord["originalAuthorPublicKey"]); - // Rename pseudonymityAliases columns (v38 → v39) if (currentDbVersion < 39 && srcTable === TABLES.PSEUDONYMITY_ALIASES) { if (srcRecord["originalAuthorSignerPublicKey"] !== undefined) { srcRecord["originalAuthorPublicKey"] = srcRecord["originalAuthorSignerPublicKey"]; delete srcRecord["originalAuthorSignerPublicKey"]; } if (srcRecord["originalAuthorDomain"] !== undefined) { srcRecord["originalAuthorName"] = srcRecord["originalAuthorDomain"]; delete srcRecord["originalAuthorDomain"]; } } + + // The alias reverse-lookup column (v41 → v42, issue `#351`).

Do not return undefined when every post sort fails.

The publish loop reaches generateCommunityPosts(). When all sorts throw, the generator records failedSorts but returns undefined. ipns-publishing then skips reportFailedPageSorts(), clears the stored posts, and publishes a record without posts. Propagate this failed generation at the boundary so the publisher reports the failures and retains the previous feed or aborts the publish.

Preserve own "__proto__" keys during canonicalization.

Unknown fields are stored in extraProps, then the database row mapper passes them through withSortedKeysDeep. An own "__proto__" key is dropped and changes the output prototype. The reconstructed signed comment can then differ from its stored CID, causing page reconstruction or comment verification to fail. Apply the same protection to withSortedKeys.

…oring wire replies (#351) Reverts the `commentUpdates.wireReplies` column: keeping every signed reply tree on disk doubled the comment data. Nothing holds a board's replies at once now: - Posts are loaded lean; entries are serialized a batch of posts at a time from one indexed read of their subtrees (`queryRepliesUnderPosts`, by postCid), and a page fetches the entries it does not hold when built. Serialized entries persist across generations while the CommentUpdate's updatedAt is unchanged, under a byte budget derived from the heap limit, so a steady board re-serializes only the posts that changed and publishes again in a fraction of a second. - A requireReplies post sort streams too: `score` receives each post's whole subtree, loaded one batch of posts at a time in scoring order, instead of every reply of the board. - The reply-scope query no longer runs the recursive CTE, which scanned the board per call (0.8 s per comment at 112k comments): the direct children are read lean and their listed subtrees walked level by level by primary key. - DB stays at v42 for the alias reverse-lookup column and the indexes. 20k posts / 1.1M nested replies, nine sorts: about 60 s inside a 2 GB heap for 6.7 GB of pages; 2k posts: 1.2 s cold, 0.2 s with the cache warm; whole cycle for 2k posts / 113k comments 27 s.

Fix migration ordering and cover pre-v39 alias rows. When _copyTable migrates a database below v39, the v42 backfill checks for originalAuthorPublicKey before the v38→v39 rename creates it. The row is then renamed with originalAuthorSignerPublicKey, but originalAuthorSignerAddress remains null, so queryCommunityAuthor misses the alias through its reverse lookup. Apply the rename before the backfill, and add a user_version = 38 fixture that asserts the derived address and reverse lookup after migration.

…sortNames (#73) - sortPageComments / instantiatePageSortFile are no longer exported: re-sorting a page is the UI's job with the package it installed; the protocol doc shows the guidance as a code block and the test util carries it as resortPageLikeAUi, which the client re-sort and active e2e suites now use. page-sort-client.ts becomes page-sort-scoring.ts (the generator's helpers only); ERR_PAGE_SORT_REPLIES_REQUIRED is gone with the sorter. - settings.page-sorts: two registry keys exporting one sortName, and createCommunity with a duplicate, both reject. - page-generation-bench: dbstat storage report per table and index, and BENCH_NO_STATEMENT_CACHE=1 to measure the statement cache.

…author aggregates (#352) The update cycle calculated each comment's CommentUpdate fields with nine statements per comment, and the author aggregate re-summed the author's whole comment and vote history for every one of their comments: 440 s per cycle on a 2k-post / 113k-comment board with 80 authors, 89% of it in that aggregate. - queryCalculatedCommentUpdates: one statement per field group per chunk of <=4096 comments (votes, counts, last reply, last child, moderations, author edits, numbers, aliases, author aggregates + mod edits). Counts and lastReplyTimestamp stay recursive CTEs, anchored on every parent of the chunk and grouped by root, so the semantics are unchanged and a stale stored row still self-heals. IN lists are NULL-padded to powers of two so the statement cache holds at most 13 variants per query. - Author aggregates are computed once per distinct (address set, domain) and memoised for the cycle: queryCommentsToBeUpdated already re-flags every comment of a touched author, so all of them carry the same aggregate. - updateCommentsThatNeedToBeUpdated runs per depth across the whole board (was per post per depth): one batched read and one upsert per depth. calculateNewCommentUpdate takes the precomputed input and still reads it itself for single-comment callers. - queryCalculatedCommentUpdate is the batch of one; the per-field statements it replaced are deleted, queryCommentFlagsSetByMod and _queryIsCommentApproved stay for their other callers. - Equivalence test seeding votes, moderations, author edits, aliases, pending, removed, deleted, foreign-address and update-less comments: batched == per-comment for every comment, across the chunk boundary, and the memo is reused. - Bench: one author per 25 posts (BENCH_POSTS_PER_AUTHOR), per-iteration CPU user/system and peak RSS, DB file and dbstat sizes at the end of a run. 2k posts / 113k comments / 80 authors, whole cycle, median of 3: 440 s -> 23 s, CPU 445 s -> 35 s, peak RSS 2.5 GB -> 2.7 GB, DB 239 MB -> 235 MB.

This one runs syncIpnsWithDb's body phase by phase against the test server's daemon, times every kubo method the cycle touches, and reports the heap the cycle still holds when the record goes out. BENCH_STUB_KUBO=1 gives the same board with the stub, which is how the daemon's share is attributed. Seeded cids are real CIDv0 strings and the seeded signature carries a real 32-byte public key: a published record is schema-parsed and its pages are parsed back after the publish, and placeholders throw there. Page byte sizes are unchanged.

…355) The cycle held every comment's whole CommentUpdate, inline reply pages included, from the first depth until the record was published: the array updateCommentsThatNeedToBeUpdated returns was carried all the way to syncPostUpdatesWithIpfs, which needs the posts' rows to write their MFS files and nothing but the cid of every other comment. updateCommentsThatNeedToBeUpdated now takes an optional per-depth consumer. The publish cycle passes one and keeps the posts' rows and the cids; a caller that omits it still gets every row. Measured with test/benchmarks/update-pipeline-bench.mjs on 1,000 posts / 55,867 comments against a real kubo daemon, median of 3: heap held when the record is published 163 -> 99 MB, live heap at the end of the cycle 169 -> 104 MB, CPU +2%.

…ated (#355) The publish cycle still held every post's CommentUpdate - the inline reply page is the bulk of a row - from the depth-0 pass until syncPostUpdatesWithIpfs ran at record-build time: 76 MB of JSON for 1,000 posts, growing with the board. syncPostUpdatesWithIpfs is split into writePostUpdatesToMfs, which takes one slice (the purge filter, the writes, the flush and the post-write purge re-check of issues #142 and #304), and the whole-cycle wrapper that callers holding a cycle's rows still use. A depth is now calculated in slices of 2,000 - 500 cost the phase 28%, 2,000 is unchanged - and updateCommentsAndWritePostUpdates writes each slice's posts and drops the rows, keeping only cids. Marking the comments as published stays where the whole-cycle sync ran, so a cycle that fails before it leaves every comment flagged for the next one. Measured on 1,000 posts / 55,867 comments against a real kubo daemon, median of 3: heap held when the record is published 99 -> 4 MB, live heap at the end of the cycle 104 -> 10 MB, peak heap 510 -> 406 MB, peak RSS 1,960 -> 1,856 MB, CPU -4%. Wall time unchanged; the MFS writes moved from the record phase into the CommentUpdates phase.

…ine bench (#355) A 100k-post board is 2.7 GB of SQLite, which does not belong in the working directory the PKC default puts it in, and its size is part of what the run is measuring. BENCH_DATA_PATH picks the directory; the seeded and final sizes of the database, its write-ahead log included, are reported next to the timings.

33-37: 🎯 Functional Correctness | 🔵 Trivial | ⚡ Quick win

Deduplicate inclusive attribution by function label, not by node id.

seen tracks node ids. A recursive function appears as several distinct nodes in one stack, and each node produces the same label. bump(inclusiveByFn, label, us) then adds the sample's time more than once for that function, so its inclusive total can exceed the sampled total and the printed percentage can exceed 100%. Several update-cycle steps recurse over reply subtrees, so this affects the numbers the script is meant to report.
♻️ Proposed fix to count each function once per sample
-    const seen = new Set();
-    for (let current = id; current !== undefined && !seen.has(current); current = parent.get(current)) {
-        seen.add(current);
-        bump(inclusiveByFn, label(nodes.get(current)), us);
-    }

+    const seenLabels = new Set();
+    for (let current = id; current !== undefined && !seenNodes.has(current); current = parent.get(current)) {

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Validate the registry result before invoking it.

published?.name is remote data. An unknown name makes factory undefined. An inherited key such as constructor can also resolve outside the registered sort set. Reject names that do not resolve to an own function before calling the factory.

Proposed fix

-const factory = registry[published?.name ?? sortName]; +const factoryName = published?.name ?? sortName; +const factory = + Object.prototype.hasOwnProperty.call(registry, factoryName) ? registry[factoryName] : undefined; +if (typeof factory !== "function") throw new Error(`Unknown page sort: ${factoryName}`); const options = published?.publicOptions ?? {}; // the option set the sort ran with, reserved options included const file = factory({ pageSortSettings: { name: published?.name ?? sortName, options } });

Return a valid CID in both cid and path from both Kubo stubs. PageGenerator._buildAndAddPage returns addRes.path as the page CID, so update-cycle-profile.mjs currently returns the invalid value "x". The pipeline stub also uses non-decodable "0"-padded values, while its safeParse result is ignored. Export fakeCid from page-generation-bench.mjs, generate one value with fakeCid(++added), and return it for both fields in each stub.
