Seven correctness defects found by the review are fixed and tested; the efficiency, reuse and documentation findings are applied; make test-core, make build (zero warnings) and make test-quick pass. Two items are deliberately left: the test-only V7 facade (Q101) and the Req 5.4 capture arm, which stays ~1.8× over budget until V9 (Q89). The release gates in prerequisites.md (device migration check, accessibility-size eyeball, test-performance-chunks) are open and recorded in OVERVIEW.

If you started a novel on one site and continued it on another, the app held two separate Works and refused to join them, because “which site is this Work on?” was answered by a single piece of text stored on the Work.
Now a Work holds a set of site memberships. A membership is a small record saying “this Work is also on example.com, and here is that site's address for it, and here is how the app recognises it there.” A Work with two memberships is one Work in the library, with one list of chapter notes, that happens to live on two sites.
The one-site assumption was not a small field; it was baked into matching, merging, the duplicate scan, validation, the backup file and the screens. Lifting it lets the library describe what readers actually do.
The delicate part is that the change is irreversible for stored data. The app has to convert an existing library, and once it has, an older build cannot open it. Most of the engineering here is about doing that conversion safely: never destroying the old values before the new ones exist, refusing to open rather than half-converting, and being able to run the conversion again from scratch if it fails halfway.
WorkSiteMembership row: one per (Work, site), carrying hostname, the app's identity fingerprint for the Work there, which rule produced it, and the confirmed web address.EntryCitations) serialised into a single column. “Blob” means the database sees opaque bytes and the app decodes them. Same trick for a title pattern's definition."8" only after the conversion has finished and checked itself. A build that does not recognise the digit refuses to open rather than damaging the library; the share extension opens only "8" and tells you to open the app if it finds "7".Six phases, one commit-group each, plus two review commits (25 commits, 236 files, +21,083 / −5,109).
AsterismSchemaV7.swift became a frozen snapshot; AsterismSchemaV8.swift declares the live schema (V7's eight models plus WorkSiteMembership and WorkDistinctPair) and AsterismV8MigrationPlan = [V5, V6, V7, V8], three .lightweight stages. Models.swift moved the live classes into extension AsterismSchemaV8 and added Entry.citationsData / TitlePattern.definitionData. V8PopulationPass.swift fills them; the bootstrap gained a BootstrapState.markerLagging("7") arm.LibraryValidator gained a membership arm and dropped the Work-side site checks; new MembershipReconciler.swift re-attaches orphans, heals a missing membership from an Entry's hostname, and de-dupes memberships and pairs. SiteReconciler.repin walks memberships; deletion and duplicate collapse follow them.WorkSnapshot carries memberships; LibraryRepository.hostnameWorks is the shared answer for thirteen call sites; Work.create / createCarrying are the only creation doors; the Work URL is per membership; WorkMergePlanner owns destination ordering and per-site identity re-derivation; DuplicateScan gained per-membership keys, a cross-site title edge and the dismissal index.WorkDetailView draws one SiteLabel per membership in a FlowLayout, one link per membership with a URL, “Remove from <host>”, and a hostname menu for URL-identity review. WorkMergeView reuses WorkRow and WorksSearchFilter; WorksView carries a dismissal pill per partner; SitesView shows Works per site.BackupV7Document/Payload/Codec/Exporter/reference validator replace the 6/7 set outright; BackupV4Types, BackupV5Types, BackupV6Types, ArchiveWorkRecord, EntryRuleCitations and the old golden file are deleted.M4MembershipScalePerformanceTests reports the pass, the reconciler and the merge picker; its findings produced the hostnameWorks rewrite and Decision 5's tiered reconcile.Frozen snapshots plus an additive schema. SwiftData's lightweight stage runs inside ModelContainer.init, so a stage that dropped the old columns would destroy the source before any post-open pass could read it, and a .custom stage would also run inside the share extension, which must never migrate. So V8 only adds (Decision 3); every superseded column survives unread until V9 (T-2272).
The marker ladder. extensionOpenableMarkerVersion = "8", appOpenableMarkerVersions = ["7", "8"]. The "7" arm runs: open (the stage converts) → V8PopulationPass.run → MembershipReconciler.run → assertComplete → publishReadiness() → validation. The marker goes after the work it certifies, so a throw leaves "7" on disk and the next open re-enters the arm. The pass certifies itself because the validator tolerates every state it repairs (Q35).
Columns lead, blob mirrors (Decision 4). Phase 1 moved the storage of citations, not the readers: eight writers still write the seventeen columns and five readers still read them. So the columns stay authoritative for one version and the blob is a value-guarded mirror. LegacyColumns.refreshCitations(on:) re-derives the blob from the columns and every column writer calls it as its last statement; the population pass calls the same function. Without this, the first re-teach on a migrated library refused itself — a commit validates what it just wrote, and it was reading the pre-write blob against post-write columns.
fileprivate columns and LegacyColumns. A deprecation annotation on a @Model property emits an unsilenceable macro warning per column, so access control enforces instead (Q34). Work's six site/identity/URL columns are fileprivate (Q59) because WorkSiteMembership carries fields of exactly those names and a grep cannot tell them apart; fileprivate also shuts @testable out. ModelContractTests pins an exact, shrinking allowlist of files naming a retained column (Q43) — a file that stops reading one fails too.
Tiered reconciliation (Decision 5). reconcileAfterSync over a converged library measured 1.081 s against a 1.82–2.00 ms band, because both new passes were unconditional and whole-library. They are now gated on three counters the tolerance scan already had the traversal to produce. The .arrival tier (the sync debounce) runs the cheap phases unconditionally and the whole-table phases only where a counter is non-zero — 0.030 s for a no-op. The .full tier stays unconditional, because Decision 4's value guard is the only reader that can see a blob gone stale under its columns, and no counter can see that state.
Single-door constructors. Work.create inserts the Work and its first membership; Work.createCarrying is the internal door for paths that derive an identity first — a distinct name rather than an overload, because an internal overload of a public function silently resolves to the public one outside the package (Q69).
Fetch, don't traverse. Delete related rows by a predicated fetch on the foreign key, never through the inverse array — an inverse array hands back future-backed rows, and deleting one then rolling back crashes inside SwiftData's snapshot creation (Q55), which is exactly what every refusal path does. And on any path touching many rows, fetch the related table and group in memory: hostnameWorks answers in three predicated fetches with no traversal, halving the capture breach (0.35 s → 0.17 s, Q84). This is why the models carry a scalar workID beside the work relationship.
The lagging V7 writer is the shape everything is designed against. Req 2.7 accepts that a V7 device can keep syncing after another has migrated, writing Works with no membership and rewriting citation columns under a populated blob. Three mechanisms cover it: nil-blob fallbacks (Entry.citations → LegacyColumns.citations(from:), Q36); populateCitations's value guard so a populated-but-stale blob is re-derived rather than skipped; and MembershipReconciler.heal. Decision 5's arrival tier sees exactly this shape in its counters — except the per-hostname miss.
Undecodable blobs. The getters throw and the validator raises unreadableCitations / unreadableTitlePattern under the row's hostname. SiteReconciler.rewriteCitations no longer decodes first (Q93) — one bad row used to throw out of the enumeration and abandon the whole consolidation, leaving every later Entry citing a version its rule no longer held. refreshCitations nils the blob when the encode fails, which assertComplete would throw over — accepted as unreachable (Q118). GroupOrdering.canonicalDefinition falls back to the canonically-encoded legacy columns rather than a "raw:" constant, which had made two differently-broken patterns compare converged (Q95).
Membership-less Works are on no site, not on the same site. Set disjointness is vacuously true of two empty sets, so the xt edge formed between every pair of membership-less same-title Works and Set(hostnameSets).count > 1 read {[]} as one site — .silentlyResolvable, and commitCollapses deleted a row the reader was never asked about. Both halves are guarded (Q90, Q91): a tolerated, transient state must never trigger an irreversible delete.
Distinct pairs leaked through defaulted parameters. works(), canonicalWorkIDs(normalising:) and BackupGroupProjection.project took a defaulted [], so three set builders rebuilt an edge the reader had dismissed while Recent and the reconciler honoured it. The defaults are gone rather than corrected (Q92). collapseMemberships may leave two identical pair rows; dedupePairs cleans them, deliberately (Q56).
Recency-gated import. commitMemberships' update branch is gated on the Work ids commitWorks applied (Q82). A membership is a Work's site presence, so an archive too old to move the Work must not move its hostname, identity triple, confirmed URL or createdAt — and createdAt orders the site line, picks the dedupe survivor and decides what the superseded columns mirror, so one older archive would reverse all three at once. Inserting stays unconditional.
A heal must never take the primary slot. Q51's “the Work's createdAt” is device-independent but ties with the membership a migrated Work already carries, and the tie falls through to two random UUIDs — so a heal became primary half the time, moving Req 6.4's glyph, moving what the columns mirror, and handing the export a Work record naming one site and citing another's rule. Q62: latest existing createdAt plus one millisecond. Relatedly, Work.membership(for:) answers with the dedupe survivor (Q61), not the presentation-order first row, or a state-none twin arriving before reconciliation makes identity-first matching mint a second Work.
Single-site assumptions in disguise. Torn-group Work URL propagation read the carrier's primary membership and wrote the row's primary membership, publishing a b.example address as the a.example link (Q94). The duplicate-resolution sheet folded both sites' URLs under one hostname (Q65). commitWorkURL takes the hostname as a parameter, so it must refuse a URL whose host is not that membership's — WorkURLPlanner.isOnHost, shared with the validator, which throws it as a tuple failure rather than tolerating it (Q66, Q97). projectWorkURL has no Work-wide overload (Q73).
Commit gates refuse only an introduced diagnosis. The bare inequality read a cleared diagnosis as a changed one, so removing the very membership whose malformed URL diagnosed the site was refused, naming the diagnosis “unknown” (Q67). One introducedDiagnosis(across:in:) now serves all five gates, extending the rule to merge and duplicate resolution (Q100).
Work by siteHostname go through hostnameWorks; everything downstream reads a WorkMembershipBasis rather than a scalar.refreshCitations, and the ModelContractTests allowlist is what keeps that discoverable. The Work-side mirror is maintained at membership write sites only, and never after a rule renumbering (Decision 4 amended) — Work.urlIdentityRuleVersion can be stale, harmless precisely because nothing reads it.LibraryToleranceScan walk. A third would be one too many.materializeArchive applies no coverage — a graph built from the archive alone can only agree with itself (Q83).V7RecordedStoreFixture seeds two Entries, because one validator-accepted Entry cannot carry all seventeen citation columns (Q46); SiteRelationshipPopulationPass stays test-only but now pins WorkSiteMembership.site as well (Q103).ModelContainer over a frozen snapshot pollutes SwiftData's global entity registry for the process. After the import gates opened an in-memory container over AsterismSchemaV7, saves through the live container silently dropped the columns V8 had added. Any scratch container must be built over the live schema.Numbers to watch.
duplicate-settling-pass at 9.31 s against an 11 s ceiling — 85% of its headroom. The next change that adds a second breaches it.reconcile-noop-coherent 1.09 s vs a 1.82–2.00 ms band, and derivatively duplicate-observation-pass 2.73 s vs a 2 s budget. Both close when V9 drops the columns and phase 2.diagnosis-refresh arms deepened a pre-existing breach: 0.300–0.302 s → 0.369–0.370 s against a 250 ms budget that was already a known issue, still inside the 400 ms ceiling (Q119).Correctness edges.
heal is gated on worksWithoutMembershipCount, which counts Works with no membership. Req 8.1's “post-sync reconciliation SHALL add a membership” is satisfied only at the full tier..rule membership whose cited rule row is absent reads as legacyUnverified and stops identity-first matching for that membership (Q72), so a slow-syncing rule row silently changes matching behaviour.@Attribute(.unique), so Req 1.1 is enforced by local refusal plus dedupeMemberships; Req 2.6 sanctions the transient duplicate.V9 / T-2272 inherits the ~35 superseded columns, LegacyColumns and both rewrite helpers, V8PopulationPass phase 2 (and most of the reason two of Decision 5's counters exist), the read-time citation regime, the V5 stage, the version-integer retirement, the import gate diff and the test-only facade. The frozen V8 snapshot must be written with the dead columns present.
Not exercised on hardware. Every figure is host-only. The "7" → "8" migration has never run against a real device library; that, the two-device update order, the three-membership site line at accessibility text sizes, and a re-run of make test-performance-chunks are the open Before-Release items.
Packages/AsterismCore/Sources/AsterismCore/V8PopulationPass.swift
Why it matters. Three chunked, idempotent phases (memberships, citations, definitions) reading the retained columns through LegacyColumns and writing the new rows and blobs, with a save per dirty chunk. assertComplete throws unless every Work with a non-blank siteHostname has a membership, every Entry has a citation blob, and every TitlePattern whose ten columns form a legal arm has a definition blob. The bootstrap arm publishes marker "8" only after the pass, the reconciler and assertComplete all succeed. This is the irreversible part of the branch. Everything downstream assumes each Work has exactly one membership carrying its former hostname, and that assumption is only true because this pass ran and certified itself.
Packages/AsterismCore/Sources/AsterismCore/Models.swift
Why it matters. The blob is re-encoded from the columns, value-guarded, as the last statement of every citation column writer. The population pass calls the same function, so one piece of code reconciles both homes. This is the invariant that makes the two-homes period safe, and it is maintained by convention at eight call sites rather than by the type system. A ninth writer that forgets it reintroduces the bug.
Packages/AsterismCore/Sources/AsterismCore/Models.swift
Why it matters. Work's six site/identity/URL columns became fileprivate, with LegacyColumns.membership(from:) the only read door and update(_:_:) / setSite(_:on:) the only write doors; suites reach them through Work.legacyColumns / setLegacyColumns in MembershipTestSupport.swift. Other retained columns are internal. ModelContractTests pins both that the columns are still in Schema(...).entities and the exact set of files naming one. About 35 columns ride in the schema unread for one version. Whether V9 can drop them safely depends entirely on whether the reader list stayed finite and known.
Packages/AsterismCore/Sources/AsterismCore/MembershipReconciler.swift
Why it matters. Four phases: re-attach an orphan whose Work has arrived; heal an Entry whose Work holds no membership for its hostname (state none, pinned to the hostname's winner Site row); dedupe memberships by (workID, hostname) under the rule-derived > legacy-unverified > none, earliest created, lowest id order; dedupe WorkDistinctPair rows keeping the latest recordedAt. The arrival tier runs the cheap phases unconditionally and the whole-table phases only where a LibraryToleranceScan counter is non-zero. This pass is both the repair mechanism for every tolerated multi-site state and, unguarded, a 1.08 s whole-library walk on every sync debounce. The gating is what makes the feature affordable.
Packages/AsterismCore/Sources/AsterismCore/DuplicateReconciler.swift
Why it matters. A loser's membership for a hostname the survivor already holds is deleted; one for a hostname the survivor lacks is moved to the survivor. WorkDistinctPair rows naming a loser are re-pointed (ids re-sorted) and deleted when both ends coincide. Rows are reached by chunked id-set fetch, never through work.siteMemberships. The merge commit now calls this rather than reimplementing it, and the dismissal table is read once by the caller. A merge and a reader-confirmed duplicate collapse are the same operation, and the two spellings had already drifted once. This is where a Work's site presence can be silently lost.
What to look at. DuplicateReconciler.collapseMemberships (DuplicateReconciler.swift:731-800) and its use from LibraryRepository+WorkMerge.swift's commitMerge
Packages/AsterismCore/Sources/AsterismCore/LibraryRepository+ConfirmImport.swift
Why it matters. The update branch is skipped unless the record's workID is in appliedWorkIDs — the Work ids commitWorks actually applied — so an archive too old to move the Work cannot move its hostname, identity triple, confirmed URL or createdAt. Inserting stays unconditional. A record naming an absent Work imports unattached with workID kept, so the reconciler re-attaches it later. Import into a non-empty library is the one path where an older archive can write over newer synced state, and a membership carries three things that order downstream behaviour.
What to look at. commitMemberships (LibraryRepository+ConfirmImport.swift:405-478) and commitDistinctPairs (:480)
Packages/AsterismCore/Sources/AsterismCore/LibraryRepository.swift
Why it matters. The hostname's attached memberships name their Works by workID; the Works come back by chunked id set; the memberships of those ids come back the same way and are grouped in memory. groupingMemberships: false skips the third (most expensive) fetch for callers that want only the Work rows — worksOn and the validator's per-hostname pass. This is the shared answer for thirteen call sites including the share extension's capture path, and the rewrite is the whole of a halved performance breach.
What to look at. HostnameWorks and hostnameWorks(hostname:context:groupingMemberships:) (LibraryRepository.swift:1608-1700), with worksOn now a thin wrapper
Originally V8 would drop Work.siteHostname and the identity/URL columns outright, on the grounds that the population is a single user whose devices update together and a dual-write window protects a lagging-build scenario nobody has. Superseded by Decision 3 — the no-dual-write half stands, the physical drop moves to V9. The rejected alternative “keep the columns but stop writing them” was called out as worse than removal, because a stale column read by an old build beats no column; V8's marker refusal is what makes that objection moot.
Only 7/8 is readable; the 6/7 decoder is deleted with the format change. Same stance as data-model-cleanups Decision 2. Consequence with teeth: a failed V8 migration has no in-app archive recovery — the only rollback is reinstalling the V7 build and restoring a 6/7 archive there, which is why prerequisites.md asks for those exports before starting. Req 2.4 (a failed migration leaves the library unopened) carries the weight the decoder would have carried.
The V7→V8 stage is lightweight and additive: two tables, two columns. The marker-gated V8PopulationPass copies the old columns into the new rows after the open. Why not drop: SwiftData's lightweight stage runs inside ModelContainer.init, so a dropping stage destroys the source before any pass can read it; a willMigrate custom stage runs in the share extension, which must never migrate; the only other route is the retired V3→V4 sidecar shape. Cost: ~35 dead columns ride for one version and ModelContractTests has to pin that none has an accessor. Req 10.3's “removed” therefore reads as removed from the live model surface in V8 and from storage in V9.
Phase 1 moved the storage and not the readers — eight writers still write the columns and five readers still read them — so an existence guard would populate a blob once and let it drift for ever, silently, because a nil blob falls back to the columns while a stale one does not. So: populateCitations uses a value guard, and LegacyColumns.refreshCitations(on:) is called as the last statement of every citation column writer (the task 8 amendment, after a re-teach on a migrated library refused itself). Amended twice more: task 12 did not invert the writers (Q68), and the Work-side renumbering half was deleted with the 6/7 export (tasks 20–21), so Work.urlIdentityRuleVersion can now go stale after a rule renumbering — harmless only because nothing reads it. TitlePattern.definitionData is deliberately outside the bargain and keeps its existence guard: its ten columns have no writer left.
reconcile-noop-coherent measured 1.081 s against a 1.82–2.00 ms band because both new passes were unconditional and whole-library. LibraryToleranceScan.Result gained three counters on the same terms as duplicateCandidateCount (a scalar read per row on a walk that already visits every table). The .arrival tier runs the cheap phases unconditionally and the whole-table phases only where a counter fires; the .full tier — launch, import re-fire, reader actions — stays unconditional. Why not gate both: the full tier's value guard is the only reader that can see a blob gone stale under its columns, and a counter cannot see that state by construction, because the row has a blob.
A Work can be on a site with no entries there yet (after a merge or a move), per-site URL identity needs a row anyway, and it gives the validator one rule: an Entry's Work holds a membership for the Entry's hostname. The cost is a new tolerated state — a Work with no membership — and a heal path to maintain.
Titles collide across sites, so a capture never joins a Work on another site by title alone. The duplicate scan surfaces cross-site same-title Works as manual merge candidates, never auto-collapsed, and the reader can dismiss the pair with a synced WorkDistinctPair record — otherwise a novel/webtoon pair asks to be merged for ever. Dismissal never applies to same-site identity sets.
A V7 device that keeps syncing after another migrated may write Works without memberships. The V8 build heals them from Entry hostnames and does not otherwise defend. A Work with zero memberships is a tolerated state rather than a quarantine, because it arrives from a lagging writer or a partial sync and quarantining a hostname it does not have is impossible. Single-user population; the mitigation is updating both devices.
Duplicate membership survivor: strongest identity state (rule > legacyUnverified > none), then earliest createdAt, then lowest id — earliest-created alone would let a healed state-none row discard a rule-derived identity. Duplicate pairs: most recent wins. And Work.membership(for:) answers with that survivor, not the presentation-order first row (Q61): between a duplicate arriving and the next reconcile, a state-none twin sorting first made identity-first matching read the Work as having no identity on that site and mint a second Work — a loss the reconcile cannot undo.
The validator diagnoses and never mutates, so membership repairs live in reconcileAfterSync. Q115 goes further than Req 8.1's “tolerated”: the Entry arm performs no membership test at all, because a test whose only outcome is “tolerated” produces nothing and costs a fault plus a sort of the inverse array per Entry, on a pass that runs inside every commit.
SwiftData stores a struct as a blob anyway, so one column replaces fourteen and ten; the throwing getter plus failable setter is the proven URLRulePattern.definitionData shape. Entry.identityKeyVersion becomes the EntryCitations.Identity case (rawURL / rule / composed), which is the switch the validator and archive checks were performing anyway. Q39 drops the kind: payload from WorkAssignment.pattern: it only round-tripped one of five mismatched shapes while the other four normalised silently, all five are validator-rejected, and one rule stated once beats one exception.
A pair must outlive either Work's absence and re-point by rewriting a column; relationships would nullify silently. A membership keeps a scalar workID beside the work relationship so an import- or sync-orphaned row can re-attach — and, as it turned out, so every hot path can fetch and group by the foreign key instead of faulting the relationship (Q84).
A @available(deprecated) annotation on a @Model property emits an unsilenceable macro warning per column, so access control and a test enforce instead. Most retained columns are internal; Work's six are fileprivate, because WorkSiteMembership carries fields of exactly those names and a grep cannot distinguish them — and fileprivate shuts @testable out too. LegacyColumns itself is internal because three production types read it. ModelContractTests pins an exact, shrinking allowlist rather than an empty set, so a file that stops reading a column fails too.
In the "7" arm the sequence is pass → reconciler → assertComplete → marker → validation. The validator tolerates every state the pass repairs, so it cannot certify the pass; and a library that opened on V7 must open on V8, so validation runs after the marker and opens with diagnoses rather than refusing, as the .ready arm does.
Every production Work-creation site moved to Work.create at task 8, not task 12, because task 8 made a membership-less Work a reported diagnosis and a Work born without one would have failed the task's own tests. Work.init stayed public until task 12 so the eight remaining callers kept building. The identity-bearing door is Work.createCarrying, a distinct name rather than an overload: an internal overload of a public function is a resolution hazard at every call site outside the package — the compiler picks the public one silently and the identity is dropped.
Q51 gave a heal its Work's createdAt for device-independence, which ties with the membership a migrated Work already carries, and the tie falls through to two random UUIDs — so a heal became primary half the time, moving Req 6.4's glyph, moving what the columns mirror, and handing the export a Work record naming one site and citing another's rule. Q62: the latest createdAt the Work's memberships already hold, plus one millisecond; the Work's own only where it holds none. Device-independent and stably last.
An inverse array hands back future-backed rows; deleting one and rolling back — which the deletion commit and both collapse paths do whenever validation refuses — crashes SwiftData in snapshot creation. And each traversal of an unmaterialized relationship is a fault: at 1,000 Works the capture path paid ~0.3 s of pure fault time, the whole of a budget breach. Both rules are now in docs/agent-notes/swiftdata-relationships.md as project-independent SwiftData knowledge.
projectWorkURL requires hostname: and has no Work-wide overload, because a defaulted hostname could only mean “the primary membership”, the single-site assumption this feature removes. Because the hostname is a parameter rather than derived from the URL, commitWorkURL must refuse a URL whose host is not the named membership's, or a b.example address lands on the a.example membership. The validator throws the same check (WorkURLPlanner.isOnHost) as a tuple failure rather than tolerating it: no writer produces the state and nothing repairs it.
A bare inequality read a cleared diagnosis as a changed one, so removing the very membership whose malformed URL diagnosed the site was refused, naming the diagnosis “unknown” because there was none left. The rule is diagnoses[h] != nil && diagnoses[h] != prior[h] over a sorted hostname list, and Q100 unified all five gates behind one introducedDiagnosis helper — which also fixed merge and duplicate resolution refusing on a site that was already quarantined, the site most likely to hold duplicates.
Req 4.1 offers every other Work, so there is no narrower fetch to make; torn candidates are listed and disabled rather than filtered out, because a row silently missing is the refusal-after-choosing the picker exists to prevent. The row is WorkRow(showsAllSites: true) — the library's own row, with each hostname as text beside its glyph, because a run of coloured glyphs is not a sentence a reader can check a novel against a webtoon with. Q76's picker-shaped projection was held in reserve and not built: Q76's own criterion (“over budget”) could not fire because no requirement bounds the picker, so the criterion applied was in-class-ness — 1.32 s against works() at 1.69 s and the export projection at 1.30 s.
Set disjointness is vacuously true of two empty sets, so the cross-site title edge formed between every pair of membership-less same-title Works, and Set(hostnameSets).count > 1 read {[]} as one site — the set came out .silentlyResolvable and the reconciler deleted a row the reader was never asked about. Both halves are guarded now. Q30 makes the state tolerated and transient, and a transient state must not be the trigger for an irreversible delete. The guard also makes a split membership-less Work reader workload, at the cost of a silent dedupe the next heal restores.
works(), canonicalWorkIDs(normalising:) and BackupGroupProjection.project took a defaulted [], so three set builders rebuilt an edge the reader had dismissed while Recent and the reconciler honoured it — the Works list and the export then normalised a group the reconciler read torn. A defaulted parameter is how it got in, so the default is gone rather than corrected.
SiteReconciler.rewriteCitations used to decode the blob first, so one Entry with undecodable bytes threw out of the enumeration and abandoned the whole consolidation — every later Entry left citing a version its rule no longer held, by the pass whose job is preventing exactly that. It now rewrites the columns and re-derives through refreshCitations, whose catch replaces the corrupt bytes. GroupOrdering.canonicalDefinition falls back to the canonically-encoded legacy columns rather than a constant, which had made two differently-broken patterns compare converged. And refreshCitations nils the blob on an encode failure, which assertComplete would throw over — accepted as unreachable over a closed Codable value with no floats, dates or user keys.
commitMemberships' update branch is gated on the Work ids commitWorks applied, extending Decision 8 of cloudkit-mirroring to the membership table. createdAt orders the Req 1.2 site line, picks Q23's dedupe survivor and decides what the superseded columns mirror, so one older archive would reverse all three at once. Inserting stays unconditional: a row the library does not hold cannot be regressed.
Met on the arrival path (reconcile-noop-arrival and duplicate-arrival-pass-gated both 0.030 s, from 1.080 s) and on every read, open and validation path. Not met on three full-tier labels, which Decision 5 keeps unconditional by design, plus the three diagnosis-refresh arms, where this branch deepened a breach that pre-dated it. Q119 also records a wording divergence: the requirement's “recorded bands” was implemented as the suite's budgets — a band is the spread of a measurement, a budget is what the suite asserts, and the work applied the checkable one.
WorkMergeOutcome.workURL / identityEvidence / identityDisposition and WorkVariantUnionOutcome.workURL have no production caller left — the preview renders a row per site and the resolution sheet folds per hostname — but the suites read them as the single-site answer. Deleting them is a test rewrite that belongs with the rest of the single-site surface at V9. A comment at each accessor says so.
| Severity | Area | Finding | Resolution |
|---|---|---|---|
| major | DuplicateScan cross-site edge | Two membership-less Works with the same title formed a cross-site title edge (empty hostname sets are vacuously disjoint) and were classified silently resolvable, so the reconciler auto-collapsed them — Req 5.2 forbids this. | crossSiteLinked requires both sides non-empty; any membership-less member makes the set .divergent (Q90/Q91); tests added. |
| major | Distinct pairs (Req 5.6) | DuplicateScan.workSets defaulted distinctPairs to []; canonicalWorkIDs (works(), +Groups) and BackupGroupProjection took the default, so a dismissed pair still formed a set on Works while Recent had dropped it. | Default removed; DuplicateScan.distinctPairKeys(context:) threaded through every set builder (Q92); parity test added. |
| major | SiteReconciler.rewriteCitations | Read the citation blob with a throwing getter inside the consolidation chunk loop; one undecodable blob aborted the whole reconcile pass. | Rewrites the columns, then LegacyColumns.refreshCitations (which repairs undecodable bytes) — Q93. |
| major | Torn-group Work URL propagation | DuplicateReconciler copied the carrier's primary URL onto the row's primary membership, landing one site's URL on another site's membership when memberships were ordered differently. | Per-hostname propagation via membership(for:) then refreshMembership (Q94). |
| major | GroupOrdering.canonicalDefinition | definitionData == nil fell back to the constant "raw:", so two differently-broken TitlePatterns compared converged. | Third arm over LegacyColumns.canonicalColumns; the two overloads share one canonicalJSON (Q95). |
| major | Export citation gate | requireCitationsResolve's Entry arm checked existence only; a cross-site citation passed the gate and failed inside the exporter's decode-validation as a codec error. | Same-site check added over rules and patterns; requireSameSiteRule and validateEntryRuleReference collapsed onto one predicate (Q96). |
| major | Membership Work URL host | The validator accepted a membership whose confirmed Work URL is on another host; the rule existed only at one write site, with a fourth ad-hoc host parse. | WorkURLPlanner.isOnHost shared by validator, confirmWorkURL and the app; refused like its sibling tuple checks (Q97). |
| major | LibraryValidator per-hostname path | memberships.compactMap(\.work) faulted one Work per membership row on every diagnosis refresh — the fan-out Q84 removed from capture; diagnosis-refresh deepened 0.30 → 0.37 s. | Uses hostnameWorks and its grouped memberships. |
| minor | LibraryValidator store path | graph.memberships + works.flatMap(membershipValues) faulted and sorted every Work's inverse array only to be deduped away. | Union only when graph.memberships is empty (hand-built graphs). |
| minor | collapseMemberships fetches | Whole WorkDistinctPair table fetched per deletion plan; memberships fetched per loser. | Pair fetch hoisted to the deletion phase; chunked workID-set predicate. |
| minor | Sites work count | membership.work != nil evaluated in memory inside enumerate — a relationship fault per row on the Sites screen. | Pushed into the #Predicate. |
| minor | worksOn | Paid hostnameWorks' third fetch and per-Work membership sort, then discarded the grouping at seven call sites. | Works-only arm; grouping opt-in (Q98). |
| minor | WorkMergePlanner.rank | Recomputed (with a Set allocation) twice per comparison inside the sort. | Decorate-sort-undecorate. |
| minor | Merge duplicates collapseMemberships | +WorkMerge re-implemented the membership move and pair re-point verbatim; the two had already diverged on the self-pair filter. | Merge calls DuplicateReconciler.collapseMemberships (Q99). |
| minor | Introduced-diagnosis gate ×5 | Prior-vs-introduced diagnosis logic copied in deletion, removal, merge and resolution with two variants dropping the comparison. | One LibraryRepository.introducedDiagnosis(across:context:); merge/resolution now share the deletion semantics (Q100). |
| minor | Duplicated helpers | Membership tuple validation ×2, distinct-pair survivor ×3, key structs ×5, membershipsByWorkID index ×2, JSON blob accessors ×3, currentRuleBasisEntry ×2, ComposedTitleRule unpack ×3, ToleratedEnum bypassed ×4. | Shared: tupleViolation, survivorFirstPairs, one Key + WorkPairKey, WorkSiteMembership.indexByWorkID/resolvedWorkID, decodeBlob/encodedBlob, ComposedTitleRule.init(stored). |
| minor | App duplication | MergeDestinationSearchFilter duplicated WorksSearchFilter; sourceRefusal re-implemented availability(of:); destinationRow rebuilt WorkRow; host predicate stated in the app and core; inline accessibility ids. | WorksSearchFilter.apply(to:), availability-driven refusal, WorkRow(showsAllSites:), WorkURLPlanner.isOnHost, presentation-enum identifiers, SiteLabel view. |
| minor | App hot paths | titlesByWorkID rebuilt per body evaluation (per keystroke); canRemoveMembership filtered all entries per membership per body pass. | AppLibraryModel.workTitlesByID published with the snapshot; removableHostnames derived once per load. |
| minor | Merge picker (Req 4.1) | Candidates showed hostnames as colour glyphs only. | Hostname text drawn beside each glyph; pinned via WorksRowPresentation.siteIdentifier. |
| minor | Stale docs | +Bootstrap.swift header still described the one-digit "7" world; schema-migration.md said 6/7 and .m4; ~25 design.md statements contradicted the code; CHANGELOG cited the wrong Q rows; refreshCitations doc claimed task 12 inverted the direction. | All rewritten; new agent-note swiftdata-relationships.md records Q55/Q84. |
| minor | Unrecorded divergences | Arrival-tier heal exemption, collapse moves rather than deletes, torn destinations listed, non-shared memberships re-derived, Entry arm produces no diagnosis, Req 8.6 bands-vs-budgets, diagnosis-refresh missing from Q89. | Q110–Q119 recorded; Q89 and Decision 5 amended; note under Req 8.6; OVERVIEW records the open gates. |
| minor | Test gaps | Req 3.4/3.5/8.5, hostnameWorks chunking, Req 2.4's partial-commit scenario, heal blank-hostname, reattach winner, recordDistinctPair follow-through had no tests. | 18 core cases in three new files plus two app tests; source-lint allowlist for siteMemberships readers. |
| nit | V7-shaped compatibility facade | WorkMergeWorkBasis.identity, WorkMergeOutcome.workURL/identityEvidence and WorkVariantUnionOutcome.workURL are read only by tests; the planner carries an index == 0 special case to feed them. | Kept and marked test-only until T-2272 (Q101) — deleting them would mean editing existing tests. |
| nit | Req 5.4 capture arm | Still ~1.7–1.8× over its 100 ms budget after the R1 fix. | Recorded in Q89 as going with the columns at V9 (T-2272); not fixable without the column deletion. |

Nine+ known issues, all inside `withKnownIssue` with regression ceilings+ outside; `duplicate-settling-pass` sits at 9.3 s of an 11 s ceiling.++- **Archive format 7/8 replaces 6/7 (multi-site-works, phase 5:+ Archive 7/8, T-2230).** `BackupV7Document`/codec/reference validator+ and `BackupV7Exporter` carry `WorkSiteMembership` records (hostname,+ identity tuple, rule UUID, Work URL, `createdAt`) and `WorkDistinctPair`+ rows — exported and imported sorted `(lower, higher)` so+ `MembershipReconciler.dedupePairs` matches them — with no parent id+ lists (Req 9.3): every relationship is stated by the child record.+ Citations are exported from the blob, decoded once per Entry for the+ projection. The archive validator refuses a membership whose identity+ tuple is illegal, or whose present rule is taught for another hostname,+ and tolerates an orphan membership and a rule the archive does not+ carry (Q54/Q72); the export keeps its provenance-raw guards beside the+ new blob-decode refusal (Q80). The 6/7 decoders, `BackupV4Types`/+ `BackupV5Types`, `V8PopulationPass.refreshMembership`,+ `LegacyColumns.rewriteVersion` and both reconciler Work walks are+ deleted; nothing reads `Work.urlIdentityRuleVersion` any more+ (Decision 4 amended). Import of a 7/8 archive into a non-empty library+ upserts memberships from the records, gated on the Work record's+ recency like the Work itself (Q82) — an older archive cannot downgrade+ a site presence or a confirmed Work URL. `AsterismCapabilities.Gate+ .multiSite` is the current gate. Golden file `backup-7-8-golden.json`+ is byte-pinned. Tests: `BackupV7ArchiveTests`,+ `BackupImportTransactionTests`, `BackupExportDegradedRefusalTests`,+ `EnumTolerancePolicyTests`.++- **The app shows every site a Work is on (multi-site-works, phase 4:+ App Presentation, T-2230).** The Work page's site line is one row per+ membership — glyph, hostname, identity chip and a link per site+ (`work-detail-site-<hostname>`, `work-detail-link-<hostname>`) — with a+ site picker for the Work URL when there is more than one membership+ (a draft whose host is not the selected site is refused by name before+ projection, Q66), an identity review menu over the unchanged label+ (Q33), and "Remove from <host>" offered only for an entry-less,+ non-last membership behind the delete-style confirmation. A committed+ merge navigates to the target (Req 4.6; the destination is keyed by+ `.id(workID)` so the detail view does not keep the deleted source's+ model). The merge picker offers the whole library in the planner's+ order with search that only narrows (Q63), disables quarantined and+ torn destinations — and a quarantined source — with a reason, and the+ preview renders `WorkMergeOutcome.sites` per site including the+ discarded Work URL, now a field on `WorkMergeSiteOutcome` rather than+ a read-back of the audit text (Q78). The library row's open label+ names every hostname (Req 6.4) and carries a "Not the same work" pill+ per other member of a dismissable duplicate set, recording a+ `WorkDistinctPair` and scheduling the reconcile; the Sites list shows+ Works per site. `WorkTypeDisplay.Kind.legacy` is gone (Q44). Tests:+ `WorkDetailModelTests` (multi-site suites), `WorkMergeModelTests`,+ `WorksRowPresentationTests`.++- **Matching, merge and duplicates work across sites (multi-site-works,+ phase 3: Matching, Merge and Duplicates, T-2230).** `WorkSnapshot`+ carries its memberships (`primaryHostname`, per-site identity and Work+ URL); capture, move, reparse and re-teach match through the membership+ for the capturing hostname (`ComposedWorkBasis.identity`,+ `Work.applyURLIdentity(_:on:)`), and `Work.init` is no longer public —+ `Work.create`/`createCarrying` are the only doors. The Work URL is per+ membership (`projectWorkURL(hostname:)`, refused when the URL's host is+ not the membership's, Req 3.6). A merge crosses sites: memberships are+ unioned, the answer is given site by site (`WorkMergeOutcome.sites`),+ the audit line reads `Work URL (<hostname>): …`, and the destination+ list comes from `WorkMergePlanner` alone. The duplicate scan links Works+ across sites, a `.divergent` set is never collapsed silently (Req 5.3),+ the reader can record a `WorkDistinctPair` ("not the same work") that+ both scan and reconciler honour, and the resolution sheet folds per+ hostname. Membership removal refuses the last membership and validates+ every hostname the Work touches, as do deletion and merge; the Sites+ screen counts Works per membership and the markdown export lists every+ site. Review fixes: Work's six retained columns are now `fileprivate`+ in `Models.swift` so the compiler enforces Q34 (Q43 amended);+ `LegacyColumns.refreshMembership` mirrors the primary membership —+ and resolves the rule version — after removal, merge, resolution and+ every `MembershipReconciler` phase, guarded in the suites by+ `assertWorkColumnsMirrorMemberships` (without it, removing a Work's+ primary site broke backup export); a healed membership never takes the+ primary slot (Q62); `membership(for:)` uses the dedupe survivor order.+ The task-12 citation inversion is not a writer rewrite: the blob leads+ for readers and the columns are mirrored at the write site until V9+ (Decision 4 amended). Tests: `WorkSnapshotMembershipTests`,+ `WorkURLMembershipTests`, `CrossSiteMergeTests`,+ `CrossSiteDuplicateScanTests`, `MembershipRemovalTests`,+ `WorkMergePlannerTests`.++- **Validation and reconciliation follow site memberships+ (multi-site-works, phase 2: Validation and Reconciliation, T-2230).**+ `LibraryValidator` gains a membership arm — `workWithoutMembership`,+ orphan membership rows and the Entry→Work membership miss are tolerated+ states (both strictness arms, Q50; the archive refusals of Req 9.5 land+ with task 20) — reads citations through the blob, and retires the+ Work-side cited-rule resolution (a membership cites by UUID only, Q28)+ and the unrecognised-raw provenance guards (the blob types the kind).+ `Site.urlIdentityRule` joins the retired-column allowlist and the unread+ `SiteSnapshot.urlIdentityRule` is gone. New `MembershipReconciler` runs in+ the reconcile pass and the marker-lagging arm: it heals a missing+ membership from the Entry's hostname (pinned to the winner Site row,+ `createdAt` the latest its Work's memberships already hold plus one+ millisecond, so two devices heal identically without tying with a migrated+ membership, Q62 amending Q51),+ dedupes memberships and `WorkDistinctPair` rows, and streams the Entry+ table with `enumerate`. Site re-pin, Work deletion (memberships and pairs+ cascade, reached by `workID` predicate fetch — never through the inverse,+ which crashes SwiftData on rollback, Q55) and duplicate collapse follow+ memberships and pairs. Production Work creation goes through+ `Work.create`, which now carries the URL identity onto the minted+ membership (`WorkURLIdentityMint`); a 6/7 import mints or refreshes the+ membership from the record's columns until task 21. Review fix+ (Decision 4 amendment): every citation column writer ends with+ `LegacyColumns.refreshCitations(on:)`, so an in-commit validator reading+ the blob never sees a stale one — without it a re-teach on a migrated+ library was refused. Tests: `MembershipValidationTests`,+ `MembershipReconcilerTests`, `CitationBlobRefreshTests`,+ `MembershipLifecycleTests`, `CitationResolutionParityTests`.++- **Schema V8: site memberships, citation and definition blobs, the+ population pass (multi-site-works, phase 1: Schema and Migration,+ T-2230).** `AsterismSchemaV7` is frozen and `AsterismSchemaV8` adds+ `WorkSiteMembership` (hostname, URL identity, rule UUID, Work URL) and+ `WorkDistinctPair`, plus `Entry.citationsData` and+ `TitlePattern.definitionData`; the migration plan is+ `[V5, V6, V7, V8]`, three lightweight stages, store name unchanged. The+ superseded columns survive unread until V9 (Decision 3). `V8PopulationPass`+ runs in the marker-lagging arm of the bootstrap ladder, mints one+ membership per Work, mirrors the citation columns into the blob and the+ ten definition columns into `StoredPatternDefinition`, chunked and+ idempotent, and publishes marker `"8"` only after `assertComplete`; a+ failed pass leaves the marker at 7. In this phase the legacy citation+ columns stay the source of truth and reconciliation rewrites both homes+ (Decision 4). Task 12 did **not** invert the writers (Q68): the blob leads+ for readers, the columns stay mirrored at the write site, and V9 deletes+ them. Work type resolves+ from the work-type identity alone. `Work.create` is the one door that+ mints a membership (Q41, Q48). Review fixes: the pass value-guards the blob+ instead of skipping populated rows, the Work-side rule-version rewrite+ is restored so the validator and archive keep resolving after a rule+ group converges, chunk-failure resumption and mismatched citation slots+ are tested, `WorkAssignment.pattern` lost its `kind` payload (Q39).+ Tests: `V7RecordedStoreTests`, `V8PopulationPassTests`,+ `MigratedStoreCitationRewriteTests`, `EntryCitationsTests`,+ `ModelContractTests` (exact, shrinking allowlist of retained-column+ readers).+ - **One work-type directory fetch per reconciliation pass (data-model-cleanups, phase 5: Directory Reuse, T-2271).** `DuplicateScan.run` and `DuplicateReconciler.run` take thediff --git a/CLAUDE.md b/CLAUDE.mdindex d5cedc1..5cb0c89 100644--- a/CLAUDE.md+++ b/CLAUDE.md@@ -43,7 +43,7 @@ invocations where a target exists. - `make test-core` — AsterismCore package tests (host, fast, safe).

Task 22's review halved the capture arms and gated the conversion passes off the **arrival** tier (Decision 5 of that spec), so the debounce measures 0.030 s; the three that remain are full-tier passes — launch and the duplicate follow-up — and go with the columns at V9 (T-2272).

The code had to move with the reader; the tests belong where the task list put them |+| Q50 | 2026-08-26 | An Entry whose Work holds no membership on its hostname is tolerated in **both** strictness arms; the two Req 9.5 archive refusals belong to task 20 | Strictness picks how hard the *tuple* rules bite, and this is not a tuple failure — it is a state reconciliation heals (Q11, Q24), so a stricter arm would only quarantine a hostname the app is about to repair. An archive is different: it must be wholly legal on arrival, which is where the refusal lives |+| Q51 | 2026-08-26 | A healed membership takes its Work's `createdAt`, never a clock reading | Two devices heal the same Work independently (Req 2.6) and the dedupe survivor rule reads `createdAt` before `id`, so a wall-clock value would make the survivor depend on which device got there first. The Work's creation date is synced content, and it is what the population pass gives a migrated membership |+| Q52 | 2026-08-26 | `LibraryGraph.memberships` is a defaulted array | Every hand-built graph in the suites would otherwise need a new argument to say "no memberships", and an orphan row (Req 8.3) still has to be validated as a row — which a defaulted array allows and an omitted field would not |+| Q53 | 2026-08-26 | The validator's unrecognised-provenance-raw guards are retired with the move to the blob | `EntryCitations` *types* the kind, and `ToleratedEnum` maps an unknown raw to `.none` on the way in (`LegacyColumns.citations`), so there is no unrecognised value left for a guard to catch — the arm it would have refused is now unreachable |+| Q54 | 2026-08-26 | Work-side cited-rule *resolution* is retired from the validator: a membership cites by UUID alone | Req 10.4 and Q28: `WorkSiteMembership` carries no rule version, so there is no `(id, version)` pair to resolve among a Site's rules. Read-time lookups added in tasks 12 and 18 must therefore tolerate a dangling UUID rather than assume the rule is there |+| Q55 | 2026-08-26 | Membership deletions fetch by `workID` predicate, never through `work.siteMemberships` | An inverse array hands back future-backed rows; deleting one and then rolling back — which the deletion commit and both collapse paths do whenever validation refuses the write — crashes SwiftData in snapshot creation. A fetch returns materialized rows |+| Q56 | 2026-08-26 | `collapseMemberships` may leave two identical `WorkDistinctPair` rows; `MembershipReconciler.dedupePairs` cleans them | Re-pointing `(loser, C)` at the survivor can produce a pair the store already holds. Detecting it inside the collapse means a second index over a table that is tens of rows, to prevent a state the next reconcile removes under a rule (Req 5.8) that exists for exactly this |+| Q57 | 2026-08-26 | A healed membership pins to the hostname's **winner** Site row, not to `entry.site` | Two Entries of one Work on two rows of one hostname would otherwise heal onto different rows depending on which the walk reached first. The winner is what `V8PopulationPass` mints on and what `SiteReconciler.repin` would move it to anyway; `entry.site` stays as the fallback for a hostname the winners map does not name |+| Q58 | 2026-08-26 | Every citation **column writer** calls `LegacyColumns.refreshCitations` at the write site (Decision 4's in-commit half) | The population pass converges the two homes only between commits, and a commit validates what it just wrote. Refreshing at the writer is eight one-line calls against a per-commit convergence pass at seven commit sites, and it states the invariant where it can be seen: columns written ⇒ blob refreshed |+| Q59 | 2026-08-26 | Work's six site/identity/URL columns are `fileprivate` on `Work`, with `LegacyColumns.membership(from:)` / `update` the only package door and `Work.legacyColumns` / `setLegacyColumns` the only suite door (amends Q43) | Q43 recorded them as unpinnable by grep, because `WorkSiteMembership` carries fields of exactly those names; access control has no such ambiguity, and `fileprivate` shuts `@testable` out too, so the V9 drop has a finite reader list the compiler maintains. `urlIdentityRuleVersion` stays `internal` and grep-pinned: the 6/7 archive still exports it until task 21 |+| Q60 | 2026-08-26 | `LegacyColumns.refreshMembership` mirrors the primary membership **including** `urlIdentityRuleVersion`, resolved from that membership's own Site rules | The membership cites by UUID alone (Q28), so a mirror that copied the id and left the version was pairing a rule with another rule's version. Three arms: no citation clears it, a resolvable citation takes the row's version, an unresolvable one (Q54) leaves it where the citation has not moved and clears it where it has |+| Q61 | 2026-08-26 | `Work.membership(for:)` answers with the dedupe **survivor** (Q23's order); `membershipValues` keeps Req 1.2's presentation order | Between a duplicate arriving and the next reconcile, a state-`none` twin sorting first under `(createdAt, id)` made identity-first matching read the Work as having no identity on that site (Req 3.1) and mint a second Work — a loss the reconcile cannot undo. The row a lookup hands back is now the row that will still be there afterwards |+| Q62 | 2026-08-26 | A healed membership takes the **latest** `createdAt` its Work's memberships already hold, plus one millisecond; the Work's own `createdAt` only where it holds none (amends Q51) | Q51's "the Work's `createdAt`" is device-independent but *ties* with the membership a migrated Work already carries, and the tie falls through to two random UUIDs — so a heal became primary half the time, moving the Req 6.4 glyph, moving what the columns mirror, and handing the export a Work record naming one site and citing another's rule. A fixed step off synced content keeps both properties |+| Q63 | 2026-08-26 | `WorkMergePlanner.destinations` takes `WorkSnapshot`s and is the only implementation of Req 4.1's ordering; the title comparator is the planner's scalar-exact one | `LibraryRepository.mergeDestinations` restated the rank inline and sorted with `localizedStandardCompare`, so the planner's own test and the shipped picker could disagree on any title where locale collation and scalar order differ. The planner only ever read snapshot fields, so taking bases bought nothing and kept the repository out |+| Q64 | 2026-08-26 | One `rules(for membership:)` helper answers "which rules can resolve this membership's citation", and the three basis builders use it | The Merge basis resolved through `membership.site` and the re-parse and composed-teaching bases through the hostname's winner row, which answer differently for a membership pinned to a duplicate row — the state `SiteReconciler.repin` exists to converge. Callers holding the winner rows pass them as the fallback, so no fetch is added |+| Q65 | 2026-08-26 | The duplicate-resolution sheet's Work path folds Work URLs per hostname and validates every hostname of every member | Req 5.3's identical-hostname-sets guarantee covers a *silently resolvable* set only; a `.divergent` set with a torn member routes to the sheet and can span two sites. Reading the carrier's primary membership as "the set's site" folded both sites' URLs under one hostname, wrote the winner onto whichever membership sorted first, and left the other site unvalidated |+| Q66 | 2026-08-26 | `commitWorkURL` refuses a URL whose host is not the membership's hostname | The design derives the hostname *from* the confirmed URL; the implementation takes it as a parameter, which is the same statement only while a disagreeing pair is refused. Without it a `b.example` address lands on the `a.example` membership and the Work detail links to the wrong site |+| Q67 | 2026-08-26 | The commit gates refuse a diagnosis that is **introduced** — `diagnoses[h] != nil && diagnoses[h] != prior[h]` — over a sorted hostname list | The bare inequality reads a *cleared* diagnosis as a changed one, so removing the very membership whose malformed URL diagnosed the site was refused, naming the diagnosis "unknown" because there was none left. Sorting matters because the source is a `Set` and the refusal names one hostname |+| Q68 | 2026-08-26 | Task 12's citation inversion is **not** performed as a writer rewrite: the blob leads for readers, the columns are mirrored at the write site, and V9 deletes them (amends Decision 4's closing line) | Moving eight writers onto `setCitations` would make the columns the derived home mid-phase, and every remaining column reader — the archive projection, the reference checks, `GroupOrdering` — would then read a mirror maintained by eight call sites rather than by one. Decision 4's `refreshCitations` already states the invariant at the writer; V9 removes the second home rather than swapping which one is authoritative |+| Q69 | 2026-08-26 | The identity-bearing creation door is `Work.createCarrying`, a distinct name rather than an overload of `Work.create` | An `internal` overload of a `public` function is a resolution hazard at every call site outside the package: the compiler picks the public one silently and the identity is dropped |+| Q70 | 2026-08-26 | A split Work group snapshots the **carrier's** memberships | The confirmed Work URL and the site line are authored content, and the carrier is the row whose authored content the group presents. Taking the site from one row and the link from another would show the reader a pair no row ever held |+| Q71 | 2026-08-26 | `URLEvidenceWork` carries no `URLIdentityCandidate` and no membership id; Req 3.5 keys on the hostname the evidence is for | The basis is built per hostname already, so the membership is `work.membership(for: hostname)` at the write and naming it twice would let the two disagree after a heal or a dedupe |+| Q72 | 2026-08-26 | A membership in state `.rule` whose cited rule row is absent reads as `legacyUnverified`, and therefore stops identity-first matching for that membership (Q54's shape) | `WorkIdentitySnapshot.isValid` refuses a `.rule` state with no reference, so the read had to choose between refusing and degrading — and `legacyUnverified` is precisely "the value the Work holds, with no rule cited for it". `isIdentityMatch` tests `state == .rule`, so a capture against that site falls back to title matching rather than reusing an identity nothing can vouch for |+| Q73 | 2026-08-26 | `projectWorkURL` requires `hostname:`; there is no Work-wide overload | A Work URL is a site-specific address (Q8). A defaulted hostname would have to mean "the primary membership", which is the single-site assumption this feature removes |+| Q74 | 2026-08-26 | `WorkMergeOutcome` carries `sites: [WorkMergeSiteOutcome]` rather than one identity disposition | A merge is site by site (Req 4.2), so the preview has one row per site to render and the commit one disposition per site to apply. The single-disposition accessor survives as `sites.first?…` for the same-site callers that have not moved |+| Q75 | 2026-08-26 | The merge audit line is uniform across sites: `Work URL (<hostname>):` for every discarded address, including on a single-site merge | A format that dropped the hostname when there was only one would make the block's shape depend on how many sites the Work is on, which is a second rule for a reader to learn and a second golden to keep |+| Q76 | 2026-08-26 | `mergeDestinations` reads the whole library and snapshots every other Work; the entry fan-out is flagged to task 22 | Req 4.1 offers every other Work, so there is no narrower fetch to make. The cost is the per-group `snapshot` call, which faults each Work's Entries; task 22 measures it and adds a picker-shaped projection if it is over budget |+| Q77 | 2026-08-26 | `WorkBasisEntry.hostnames` exists for the contract-refresh comparison only, not for presentation | The teaching contracts compare a stored basis against a freshly derived one, and a Work that gained or lost a site between projection and commit has to refresh. Every surface that *shows* sites reads `WorkSnapshot.memberships` instead |+| Q78 | 2026-08-26 | The merge preview's discarded Work URL is a field on the outcome (`WorkMergeSiteOutcome.discardedWorkURL`, from `WorkVariantUnionOutcome.discardedWorkURLsByHostname`), never parsed back out of the audit block | The block is the reader's prose record and is carried forward into the merged Work's notes, so a source whose notes already held an earlier merge's block handed the preview a phantom address for a site this merge dropped nothing on. Q75 is about the *block's shape* — one uniform line per site — and not a promise that the block is a data channel |+| Q79 | 2026-08-26 | Tasks 20 and 21 land in one commit | The ten record types, the codec, the reference checks, the exporter, the import commit and the deletion of the 6/7 set are one atomic change; splitting them leaves an intermediate commit that does not build, which is worse than a large one that does |+| Q80 | 2026-08-26 | The export keeps its `chapterTitleProvenanceRaw` / `workAssignmentProvenanceRaw` / `workURLAssignmentKindRaw` guards (reverses their retirement in 21ef6ed) | Q53 retired the *validator's* guards, where `EntryCitations` types the kind and the refused arm is unreachable. The export is not that: an Entry whose `citationsData` is nil is read through `LegacyColumns.citations` (Q36), which reads all three through `ToleratedEnum.read(default: .none)`, so an unrecognised spelling a newer build wrote would be archived as `.none` — the silent coercion Q8 exists to refuse. The guards leave with the columns in V9, and `ModelContractTests` keeps the file on its rewrite list until then |+| Q81 | 2026-08-26 | The membership arm keeps the same-site check on its cited rule; only the `(id, version)` *resolution* is dropped (clarifies Q54) | Q54's reason is that a membership carries no version, which says nothing about the rule's hostname. A rule the payload carries is one whose `siteHostname` can be read, and an identity derived on one site by another site's rule is a value no writer produces — the Entry's identity arm refuses exactly that shape (`requireSameSiteRule`). An **absent** rule stays tolerated (Q72): there is nothing to compare, and the row reads as `legacyUnverified` until it arrives. Both the archive validator and the export's `requireCitationsResolve` carry the check |+| Q82 | 2026-08-26 | `commitMemberships` gates its update branch on the Work ids `commitWorks` applied; inserting stays unconditional | Decision 8 of `cloudkit-mirroring`, extended to the membership table. A membership is a Work's site presence, so an archive too old to move the Work must not move its hostname, identity triple, confirmed URL or `createdAt` — and `createdAt` orders the Req 1.2 site line, picks Q23's dedupe survivor and decides what the superseded columns mirror, so one older archive reversed all three at once. It also skips the memberships of a group `commitWorks` skipped as torn. A row the library does not hold cannot be regressed, so an insert needs no gate (Req 4.1) |+| Q83 | 2026-08-26 | `materializeArchive` applies no coverage; only the commit path does (design.md corrected) | `character-extraction` Q81 governs: a coverage fingerprint is validated against the *live* source's current text, and the preview materialises the archive into an empty in-memory context where the only source is the archive's own. It could only ever agree with itself. The design said `materializeArchive` applied fingerprints on a text match; the code applies them in `applyImportedCoverage` from the import's character step, and the sentence now says so |+| Q84 | 2026-08-26 | `worksOn` and the basis builders read a hostname's Works and their memberships by **predicated fetch**, never through `membership.work` or `work.siteMemberships` | Q55's rule, extended from deletion to reading: an inverse array and a to-one relationship are faults, and on the capture path there are a thousand of each. `hostnameWorks` answers in three fetches and traverses nothing, which halved Req 5.4's breach (0.35 s → 0.17 s). Order is not load-bearing: all thirteen call sites bucket by application UUID or sort by `id.uuidString` |+| Q85 | 2026-08-26 | `duplicate-observation-pass`'s breach is accepted as **derivative** of `reconcile-noop-coherent`'s, not as a second problem | It times a *full*-tier `reconcileAfterSync()`, which Decision 5 leaves unconditional on purpose. Re-measured after the gate at 2.687 s against 2.737 s — unmoved, as predicted. It closes when the full-tier figure does, at V9 (T-2272). The arrival tier's equivalent, `duplicate-arrival-pass-gated`, went 1.080 s → 0.030 s in the same run |+| Q86 | 2026-08-26 | `v8-population-pass` and `membership-reconcile-noop` ceilings tighten to ~1.5–1.6× their medians; `membership-heal-full` and `merge-destinations` stay where they are | The first two were drawn at ~2.5× a single run's band and said to tighten when a second run widened it; three runs now agree to within 1%. The heal is an isolated upper bound rather than a production cost (Q88) and `merge-destinations` is bounded as a *class* of whole-library read (Q87), so tightening either would assert something neither number means |+| Q87 | 2026-08-26 | No picker-shaped projection for `mergeDestinations`; the criterion applied is in-class-ness, because Q76's own criterion could not fire | Q76 says to add it "if the measurement comes in over budget", and the picker has no budget — no requirement bounds it. Measured at 1.317–1.344 s against `works()` at 1.677–1.743 s and the export projection at 1.290–1.312 s, all three reading the same graph with the same fan-out and none of them narrowed |+| Q88 | 2026-08-26 | `membership-heal-full` is relabelled an **isolated upper bound**, not an arrival cost | It strips every Work's membership and heals 1,000 at once. In production `V8PopulationPass.populateMemberships` runs first and mints from each Work's retained hostname column, so `heal` reaches only what that could not mint for — a blank-hostname Work (Q30), or one whose Entries are on a hostname its memberships are not |+| Q89 | 2026-08-26 | Req 8.6 at task 22's close: **met on the arrival path, and two full-tier labels stay out of band by construction** | `reconcile-noop-arrival` 0.030 s and `duplicate-arrival-pass-gated` 0.030 s (from 1.080 s) are the debounce, and capture projection halved to 0.166–0.178 s. `reconcile-noop-coherent` (1.073 s) and, derivatively, `duplicate-observation-pass` (2.687 s) and `duplicate-settling-pass` (9.271 s) are full-tier passes — launch and the duplicate follow-up — and Decision 5 keeps that tier unconditional so Decision 4's value guard has a reader. Req 5.4 also remains breached at ~1.7×, routed as a design question (7.3 of `verification-run.md`). **Amended (pre-push review):** the not-met set also includes `diagnosis-refresh-foreground`/`-after-write`/`-duplicateSiteRows`, which this branch deepened a **pre-existing** breach on — 0.300–0.302 s before, 0.360–0.367 s after, against a 250 ms budget that was already a known issue. All are known issues with regression ceilings asserted outside them |+| Q90 | 2026-08-26 | A Work with no membership is on **no** site: the cross-site title edge requires both sides non-empty, and a Work set holding a membership-less member is never silently resolvable | Set disjointness is vacuously true of two empty sets, so `{} ⊥ {}` formed an `xt` edge between every pair of membership-less same-title Works, and `Set(hostnameSets).count > 1` then read `{[]}` as one site — `.silentlyResolvable`, and `commitCollapses` deleted a row the reader was never asked about. Q30 makes the state tolerated and transient; a transient state must not be the trigger for an irreversible delete |+| Q91 | 2026-08-26 | The membership-less guard makes a **split** membership-less Work reader workload too, not only a cross-site pair | The guard is stated over the set's hostname sets, so a one-member set whose rows hold no membership is `.divergent`. It costs a silent dedupe of duplicate rows of a Work that has no site — which `MembershipReconciler.heal` gives a site on the next pass, after which the set collapses normally |+| Q92 | 2026-08-26 | Distinct pairs are threaded through **every** Work-set builder; `workSets(of:types:distinctPairs:)` and `canonicalWorkIDs(ofWorkRows:types:distinctPairs:)` lose their defaults, and `DuplicateScan.distinctPairKeys(context:)` is the one fetch | Recent passed the dismissals and `works()`, `canonicalWorkIDs(normalising:)` and `BackupGroupProjection.project` took the default `[]`, so those three rebuilt an edge the reader had dismissed. The Works list and the export then normalised an Entry group that Recent and the reconciler read torn — the disagreement Req 3.2 forbids. A defaulted parameter is how it got in, so the default is gone rather than corrected |+| Q93 | 2026-08-26 | `SiteReconciler.rewriteCitations(of:_:)` reads no blob: it rewrites the columns and re-derives the blob through `LegacyColumns.refreshCitations`, and no longer throws | It decoded `entry.citations` first, so **one** Entry whose bytes will not decode threw out of the enumeration and abandoned the consolidation — every later Entry left citing a version its rule no longer holds, by the pass whose whole job is to prevent that. `refreshCitations` is value-guarded (converged rows dirty nothing) and its `catch` replaces undecodable bytes, so the corrupt row is repaired by the pass rather than aborting it |+| Q94 | 2026-08-26 | Torn-group Work URL propagation is **per hostname**: each of the carrier's membership URLs lands on the row's membership for that hostname, and a hostname the row is not on is skipped | A Work URL is a site-specific address (Q8). The propagation read the carrier's *primary* membership and wrote the row's *primary* membership, so on any Work with more than one site it published a `b.example` address as the `a.example` link. Skipping an absent hostname keeps propagation about authored content: it carries values across a torn group, it does not mint site presence |+| Q95 | 2026-08-26 | `GroupOrdering.canonicalDefinition(_ pattern:)` falls back to the canonically-encoded **legacy columns** for a nil-blob row, not to a constant | The `"raw:"` constant gave every column-only row whose ten columns form no legal arm (Q42) one ordering key, so two rows broken in two different ways compared *converged*: the validator stopped reporting the group and the reconciler read it as needing nothing. The columns are what the row actually holds, so they are what orders it. The encoder lives in `LegacyColumns` because that enum is the only sanctioned reader of those columns (Q34, Q40) |+| Q96 | 2026-08-26 | The export's `requireCitationsResolve` checks the **site** on the Entry arm as well as the membership arm, over title patterns as well as URL rules | Q81 already said both the archive validator and the export carry the same-site check; only the membership arm had it. An Entry citing another site's rule therefore exported cleanly and failed the import's decode-validation instead — a library-shape problem surfacing as a broken file, which is exactly what this gate exists to name first. The gate now takes the pattern *records* rather than their ids, because a hostname cannot be read off a `Set<UUID>` |+| Q97 | 2026-08-26 | A confirmed Work URL whose host is not the membership's hostname is **refused** by the validator (a thrown tuple failure, becoming the hostname's diagnosis), not recorded as a tolerated state | Every other arm of the membership tuple throws, and matching them is the whole of the choice: the value is malformed rather than merely un-reconciled, no writer produces it (`commitWorkURL` refuses one, Q66), and nothing repairs it — a tolerated diagnosis would leave the Work detail linking to the wrong site indefinitely. `WorkURLPlanner.isOnHost(_:hostname:)` is the one host derivation, shared with `commitWorkURL` |+| Q98 | 2026-08-26 | `hostnameWorks` gains `groupingMemberships:`; `worksOn` and the validator's per-hostname pass take the works-only arm | The third fetch re-reads every membership of every Work on the hostname — including the ones on its *other* sites — for callers that want the Work rows and nothing else. Two fetches instead of three on the pass that runs at every commit gate |+| Q99 | 2026-08-26 | The merge commit runs `DuplicateReconciler.collapseMemberships` rather than its own membership move and pair re-point | A merge is a reader-chosen collapse (Q32), and the two spellings had already drifted once. `collapseMemberships` now takes the dismissal table from its caller (it fetched the whole table per deletion plan) and reads memberships by chunked id set, so the shared version is also the cheaper one |+| Q100 | 2026-08-26 | Every commit gate refuses only a diagnosis it **introduced**, through one `LibraryRepository.introducedDiagnosis(across:in:)`; the merge and duplicate-resolution gates change behaviour to match | Q67 established the rule for the deletion and membership-removal gates and left the other two refusing on any diagnosis, so a reader could not merge or resolve a duplicate on a site that was already quarantined — the site most likely to be holding duplicates. One helper, so the rule cannot be half-applied again |+| Q101 | 2026-08-26 | The V7-shaped compatibility facade (`WorkMergeOutcome.workURL` / `identityEvidence` / `identityDisposition`, `WorkVariantUnionOutcome.workURL`) is **kept and marked test-only**, scheduled for T-2272 | No production caller is left — the preview renders a row per site (Q74) and the resolution sheet folds per hostname (Q65) — but the suites read them as the single-site answer, and deleting them is a test rewrite that belongs with the rest of the single-site surface at V9. A comment at each accessor says so, which is what a reader meeting `sites.first` needs |+| Q102 | 2026-08-26 | `LibraryRepository`'s three `last*Count` gate fields become one stored `V8PopulationPass.Phases` | The counters were only ever read as `> 0`, once each, to build exactly that set. Storing the answer rather than three numbers and a rule for deriving it removes the only place the rule could be spelled twice |+| Q103 | 2026-08-26 | `SiteRelationshipPopulationPass` pins `WorkSiteMembership.site` as well as the Work's superseded column | The membership's Site reference is what the live code reads; the Work column is its mirror until V9. A fixture that pinned only the mirror left every membership on whichever row it was minted against — the unconverged state `SiteReconciler.repin` exists to fix — so a suite built on the pass could not tell a converged graph from an unconverged one |+| Q104 | 2026-08-26 | `ModelContractTests`' grep discipline is extended to the membership traversals: the set of files naming `siteMemberships` / `membershipValues` is pinned exactly | Q84's fetch-don't-traverse rule is a performance property, so a new reader arrives silently — nothing fails, a pass just gets slower. Pinning the set the Q43 way makes adding one a decision; pinning it *exactly* means a file that stops traversing cannot be quietly forgotten either |+| Q110 | 2026-08-26 | Decision 5's arrival tier does **not** heal a per-hostname membership miss: an Entry whose Work holds a membership on another site waits for the next full-tier pass | `heal` is gated on `worksWithoutMembershipCount`, which counts Works with *no* membership at all. A Work on `a.example` whose Entry is on `b.example` is not in that count, so the arrival tier passes over it. The state is tolerated and produces no diagnosis (Q24), a launch/import/reader-action pass is never far away, and a counter that could see it would be a fourth whole-table index on the debounce path the tiering exists to make cheap |+| Q111 | 2026-08-26 | `collapseMemberships` **moves** a loser's membership for a hostname the survivor lacks, and deletes only the rest (amends Q31) | Q31's "delete outright" is correct for the silent path only, where Req 5.3 guarantees identical hostname sets. The reader-confirmed path can now collapse a set whose members are on *different* sites (Req 5.2), and deleting there drops a site presence the reader was asked to keep. One rule serves both paths, because on the silent path nothing is ever movable |+| Q112 | 2026-08-26 | `mergeDestinations` lists torn Works; the app marks them unselectable rather than the repository filtering them out | The picker's job is to say *why* a candidate cannot be chosen (Req 4.5).

The commit that landed phase 1 (tasks 1–7) read that as "the blob is now the value": the pass wrote a blob per Entry behind an *existence* guard, and `SiteReconciler.rewriteCitations` wrote the blob where one existed and the columns only where one did not.++Neither half holds, because phase 1 moved the *storage* and not the *readers*. Every citation writer in the repository still writes the columns and none calls `setCitations` — the composed teaching commit, the re-parse commit, the articles sweep, the import mapper, the two work-assignment writers in `LibraryRepository`. And every citation reader outside `Entry.citations` still reads the columns: `LibraryValidator`'s identity, chapter and assignment arms, `BackupArchiveProjection`'s record mapper, `BackupArchiveReferenceChecks`. So an existence guard populates a blob once and then lets it drift for ever — silently, because a *nil* blob falls back to the columns while a stale one does not — and a blob-only version rewrite leaves the validator and the export citing a version no rule holds, which quarantines the hostname and refuses the archive on a library that had just migrated cleanly.++The same gap has a Work side. `SiteReconciler.rewriteCitations(of work:)` was deleted on the grounds that `WorkSiteMembership` cites a rule by UUID alone (Req 10.4, Q28) — true of the membership, and irrelevant to `Work.urlIdentityRuleVersion`, which `LibraryValidator`'s `.rule` arm still requires to resolve and which the archive still exports for import to re-check.++### Decision++Through phase 1 the legacy columns are the source of truth for Entry citations and for a Work's URL-identity citation, and the blob is a derived mirror kept in step beside them.++Concretely: `V8PopulationPass.populateCitations` uses a **value** guard — it writes the blob whenever it differs from what `LegacyColumns.citations` reads, so a row a column-writer touched after the migration is re-derived rather than skipped. `SiteReconciler.rewriteCitations(of entry:)` rewrites the columns **unconditionally** and re-encodes the blob beside them, and `LegacyColumns.rewriteVersion(_:on:)` does the Work column, called from the same loops in `SiteReconciler.repin` and `DuplicateReconciler.rewriteCitations`.++**Amended 2026-08-26 (task 8 review).** The above converges the two homes *between* commits only — the pass runs in `reconcileAfterSync` and at bootstrap, never inside one. That is not enough once `LibraryValidator` became the blob's reader (task 8): a commit validates the graph it just wrote, so a commit that wrote the columns and left an existing blob standing hands its own validation the *pre-write* citations against post-write values. After the migration every Entry has a blob, so the first re-teach on a migrated library refused itself ("absent chapter must have none provenance"), and an import into a non-empty library left the mismatch on disk for the next full validation to quarantine.++The invariant is therefore stated at the **write site**: `LegacyColumns.refreshCitations(on:)` re-encodes the blob from the columns, value-guarded, and every citation column writer calls it as its last statement — `applyEntryIdentityAndChapter` and `applyAssignmentProvenance` in the composed-teaching commit, `applyProjection` and `applyManualAssignment` in `LibraryRepository`, the articles sweep, the import's Entry mapper, `applyEntryOutcome` in duplicate resolution and `DuplicateReconciler`'s Entry fan-out. `V8PopulationPass.populateCitations` calls the same function, so one piece of code reconciles the two homes rather than two spellings of it (Q58).++**Amended 2026-08-26 (phase 3 review).** The inversion was scheduled for task 12 as a writer rewrite — every citation writer moving onto `setCitations`. That is **not** what task 12 did, and the entry is corrected rather than left describing a plan that was overtaken (Q68). The blob leads for readers, the columns stay mirrored at the write site through `refreshCitations`, and V9 (T-2272) deletes the columns, `LegacyColumns`, both rewrite helpers and phase 2 of the population pass. Swapping which home is authoritative mid-phase would have left the remaining column readers — the archive projection, the reference checks, `GroupOrdering` — reading a mirror maintained by eight call sites instead of by one, for one version, and then deleted the column anyway.++The Work side follows the same shape from tasks 12–13: `LegacyColumns.refreshMembership` mirrors the primary membership into the six site/identity/URL columns at every write site that can move a membership, and resolves `urlIdentityRuleVersion` from that membership's Site because the membership cannot supply it (Q60).++**Amended 2026-08-26 (archive 7/8, tasks 20–21).** The Work side's *renumbering* half is gone. `BackupV7Work` carries no identity (Req 9.1), so the 6/7 export was `Work.urlIdentityRuleVersion`'s last reader — the validator stopped reading it at task 8 (Q54) — and with the format replaced, `LegacyColumns.rewriteVersion(_:on work:)` and the `SiteReconciler.repin` / `DuplicateReconciler.rewriteCitations` Work walks that existed only to keep the column in step with the wire are deleted. **The Work-side mirror is therefore maintained at membership write sites only (`refreshMembership`), and never after a rule renumbering.** Nothing reads the column, so a version left stale by a renumbering is invisible; it is retained, unread, until V9 (T-2272) drops it with the rest. The Entry side is unchanged: the columns are still read — by `LegacyColumns.citations` for a nil-blob row, and by the export's Req 3.6 guards over them (Q80) — and every writer still calls `refreshCitations`.++`TitlePattern.definitionData` is deliberately **not** in this bargain and keeps its existence guard: the ten definition columns have no writer left — `TitlePattern.init` writes only the blob, `applyStoredDefinition` goes through `setDefinition`, and `ModelContractTests` pins that nothing else names them — so a populated pattern blob cannot go stale.++### Rationale++A migration that only adds has two homes for one value for exactly one version, and the only safe rule is "whichever home every reader still reads is the one that must be right". In phase 1 that is the columns, by count: one reader (`Entry.citations`) has moved and five have not. Writing both is cheap — the value guard costs one comparison per row and a converged library dirties no chunk, which is the idempotence Req 2.4 already asks for — and it makes the ordering of tasks 8–17 a free choice rather than a constraint, because a reader can move to the blob whenever its task comes up and find the same value there.++The alternative readings both fail on a real library rather than in principle. Blob-only is what phase 1 shipped, and the two regression tests added with this decision fail against it: a re-teach after migration leaves a stale blob, and a converged rule group quarantines its own hostname.++### Alternatives Considered++- **Blob-only, as implemented in `0e1821f`**: the pass populates once behind an existence guard and the reconciler writes only the blob — Rejected: it is wrong today, not merely early. The blob goes stale on the first column write after the migration, and a version rewrite that skips the columns makes `LibraryValidator` quarantine the hostname and `BackupArchiveProjection` refuse the export.+- **Dual-write from the writers now**: move every citation writer to `setCitations` in phase 1 so both homes are written at the source — Rejected: it is task 12 pulled forward into the schema phase, across eight production write sites and their suites, and it buys nothing the population pass and two rewrite helpers do not already buy. It also doubles the surface where the two homes can disagree, where the pass converges them from one place.+- **Columns-only until task 12, with the blob left nil**: skip phase 2 of the population pass entirely — Rejected: `assertComplete` and the marker generation are built on the pass finishing, `Entry.citations` would then always take the fallback path, and the archive generation (tasks 20–21) needs the blob populated to project from.++### Consequences++**Positive:**++- Every citation reader — moved or not — sees the same value, so tasks 8–17 can move readers one at a time in any order. **This holds for between-commit readers on the strength of the population pass alone; an in-commit reader (a commit's own validation) holds it only because of the writer-side refresh above.** A reader that moves to the blob inside a commit must satisfy itself that the writers feeding it call `refreshCitations`.+- A row a lagging V7 device syncs in (Req 2.7) and a row a post-migration re-teach rewrites converge on the same reconcile, by the same mechanism.+- The population pass is self-healing: an undecodable blob is re-derived from the columns rather than standing as a permanent diagnosis.++**Negative:**++- Two homes are written for one value for one schema version, and the pass has to compare rather than skip — a decode per already-populated Entry on every full run.+- `LegacyColumns.rewriteVersions` and `rewriteVersion` are transitional code with a scheduled deletion, and a reader who meets them without this entry will read them as a duplicated write.+- The inversion at task 12 is a second edit to the same three call sites, which a dual-write-now approach would have paid once.++### Impact++`V8PopulationPass.populateCitations`, `SiteReconciler.rewriteCitations(of entry:)` and `repin`, `DuplicateReconciler.rewriteCitations`, `LegacyColumns.rewriteVersions` / `rewriteVersion` / `refreshCitations` in `Models.swift`, and the eight column writers that call `refreshCitations`.++Tasks 8, 12, 15 and 19 carry the reminders this decision leaves them as rune task details in `tasks.md`; task 12 is where the inversion lands.++---++## Decision 5: Reconciliation is tiered, gated on tolerance-scan counters++**Date**: 2026-08-26+**Status**: accepted++### Context++Task 22 measured `reconcile-noop-coherent` — what `reconcileAfterSync` costs over a library with nothing to reconcile — at **1.081 s** against a recorded band of 1.82–2.00 ms and a 10 ms regression ceiling. That is ~540× its band, on the pass that runs on every remote-change debounce and once per launch, and it put Req [8.6](requirements.md#8.6) in breach. `duplicate-observation-pass` moved with it: 0.93–0.95 s to 2.737 s, about 60% of the rise being this same cost inside the reconcile it times.++The cause is not subtle. Design line 50 put `V8PopulationPass.run` and `MembershipReconciler.run` into the pass unconditionally, at every tier, and both are whole-library. The population pass fetches the whole `Work`, `Entry` and `TitlePattern` tables; the reconciler's `heal` phase enumerates the whole `Entry` table, measured alone at 0.505 s. Every one of those walks finds nothing to do on a converged library, and a converged library is the overwhelmingly common case.++Three things constrain the fix. Req [2.7](requirements.md#2.7) asks a V8 build to heal what a lagging V7 device syncs in, and the states it heals produce **no diagnosis** a gate could read (Q24, Q30) — which is exactly the argument the duplicate phase's arrival gate makes and this one cannot make the same way. Decision 4 makes the citation phase a **value** guard, not an existence guard: a nil-blob gate would skip a row whose blob is *populated and stale*, which is what a lagging V7 writer produces when it rewrites the columns under a blob the migration wrote — and a stale blob is export-visible, because `BackupArchiveProjection` maps every Entry record out of `entry.citations`. And T-2272 is where the citation regime moves, so anything built here is transitional.++### Decision++`reconcileAfterSync` runs its two V8 conversion passes **by tier**, gated on counters the tolerance scan already has the traversal to produce.++`LibraryToleranceScan.Result` gains `worksWithoutMembershipCount`, `entriesWithoutCitationBlobCount` and `patternsWithoutDefinitionBlobCount`, on the same terms as `duplicateCandidateCount` (Q58): the walk already reads every Work, Entry and TitlePattern row and already indexes memberships by `workID`, so each is a scalar read per row and no relationship is faulted.++The **`.full`** tier — launch, the import re-fire, every reader-action pass — keeps today's unconditional, value-guarded behaviour in full.++The **`.arrival`** tier runs the cheap phases unconditionally (`reattach`, a `work == nil` predicate fetch; `dedupeMemberships` and `dedupePairs`, table fetches that fault nothing) and runs `populateMemberships`, `populateCitations`, `populateDefinitions` and `heal` only where the corresponding counter is non-zero. `heal` is gated on the membership counter, the same one that gates `populateMemberships`, and deliberately after it: the population phase mints from a Work's retained hostname column, so on an arrival carrying Req 2.7's shape it runs first and heal only has to reach what it could not mint for.++### Rationale++The gate has to be a counter rather than a diagnosis because the states are tolerated and produce none (Q24, Q30) — but "produces no diagnosis" is not the same as "cannot be counted", and the pass that already walks every table for the duplicate gate can answer this one for the price of three integers. That is the whole of the argument: the arrival tier stops paying for four whole-library walks per debounce, and the answer it uses is one a pass every arrival already runs has in hand.++Tiering rather than gating both tiers is what preserves Decision 4. The value guard is the only reader that can see a blob gone stale under its columns; a counter cannot, by construction, because the row *has* a blob. Keeping the full tier unconditional bounds such a row's lifetime by the next launch, import or reader action rather than by nothing at all — and those are frequent, whereas the debounce is what fires while the reader is doing nothing, which is precisely where a whole-library walk is least worth paying for.++### Alternatives Considered++- **Accept ~1 s per debounce**: leave the passes unconditional and record the breach — Rejected. Nothing here is on an interactive path (Q45 of `cloudkit-mirroring`), so this is a battery-and-heat cost rather than a latency one, but it is a whole-library walk on every arrival for a library that in the normal case has nothing to convert, and it holds the Req 8.6 breach open indefinitely. It was the cheapest option only while the alternative looked like a rewrite; the counters make it a small one.+- **An existence gate on the citation phase (both tiers)**: skip any Entry with a blob and drop the value guard entirely — Rejected. It is Decision 4's rejected `0e1821f` shape wearing a gate: the blob goes stale on the first column write after migration, silently, because a *nil* blob falls back to the columns while a stale one does not. The export would then archive the pre-arrival citations for that row while its Req 3.6 guards read the post-arrival columns (Q80) — an archive that disagrees with the library it came from, with nothing reporting it.+- **Defer the whole citation regime to T-2272**: leave the pass alone and let V9's column drop retire phase 2 — Rejected. T-2272 removes phase 2, not phase 1 or `heal`, so it closes less than half of the regression, and it is not scheduled inside this milestone.+- **Counter gate on both tiers**: apply the same gate to `.full`, for one rule instead of two — Rejected for the reason the tiering exists: it is the full tier's unconditional value guard that converges a stale blob, and gating it would leave that state with no reader at all.++### Consequences++**Positive:**++- `reconcile-noop-coherent` returns to its recorded band, and `duplicate-observation-pass` returns near its 2 s budget, which is most of Req 8.6's breach closed.+- The arrival tier's cost over a converged library is now the cheap phases only, and Req 2.7's shape still converges on the arrival that carries it — the counters see exactly a membership-less Work and a nil-blob Entry.+- The gate reuses a walk that already runs on every arrival and every foreground, so it adds no pass and faults no relationship.++**Negative:**++- **A blob a lagging V7 device rewrites the columns under converges at the next full-tier pass, not the next arrival.** An export taken in between archives that Entry's *blob* — `BackupArchiveProjection` maps every Entry record out of `entry.citations`, so the archive carries the pre-arrival citation values — while the same projection's Req 3.6 guards (`chapterTitleProvenanceRaw`, `workAssignmentProvenanceRaw`, `workURLAssignmentKindRaw`, Q80) read the post-arrival **columns**. The archive is therefore internally consistent and simply older than the library for that row, and it stops being older at the next launch, import completion or reader action.+- **The per-hostname heal is off the arrival tier entirely** (Q110). `heal` is gated on `worksWithoutMembershipCount`, which counts Works with *no* membership; an Entry whose Work holds a membership on a *different* site is not in that count, so the arrival tier passes over it and the miss waits for the next launch, import or reader action. It is a tolerated state that produces no diagnosis either way, and a counter able to see it would be a fourth whole-table index on the path this tiering exists to make cheap.+- Two gates now decide what a reconcile pass does (duplicates, conversions), each reading its own counters off the same scan. A third would be one too many.+- The counters are transitional: V9 (T-2272) drops the columns, `V8PopulationPass`'s phase 2 and most of the reason two of the three exist.++### Impact++`LibraryToleranceScan.Result` and `LibraryToleranceScan.scan` (three counters), `LibraryRepository.refreshDiagnostics`'s latch block and the three `last*Count` fields beside `lastDuplicateCandidateCount`, `LibraryRepository.populationPhases(tier:)` / `membershipHealRuns(tier:)`, `V8PopulationPass.Phases` and `run(phases:)`, `MembershipReconciler.run(heals:)`, and design.md's `reconcileAfterSync` order paragraph.

The pass certifies itself, because the validator tolerates the states it repairs. A Work with blank `siteHostname` and no membership is left as the tolerated state below. `reconcileAfterSync` also calls `V8PopulationPass.run` (step 3 below): rows a lagging V7 device syncs in after migration get their blobs and memberships on the next reconcile, with the same guards.

It ended the phase with a **5 s regression ceiling** rather than unbudgeted (Q86): three runs agree on ~3.22–3.24 s to within 1%, so ~1.5× the median is a band that catches a regression without asserting a number the measurement does not support. ### Reconciliation -`reconcileAfterSync` order: (1) reconcileWorkLists → (2) `SiteReconciler.run` → (3) **`V8PopulationPass.run`** → (4) **`MembershipReconciler.run`** → (5) re-validate repaired hostnames → (6) `WorkTypeReconciler.run` → (7) duplicate scan + reconciler.

Unconditional at every tier, they cost a converged library 1.081 s per pass against a 1.82–2.00 ms recorded band — four whole-table walks on every remote-change debounce. So: the **`.full`** tier (launch, the import re-fire, every reader-action pass) runs all three population phases and the heal exactly as above, and must — phase 2 is a *value* guard (Decision 4) and is the only thing that re-derives a blob a lagging V7 writer left stale by rewriting the columns under it, a state no counter can see. The **`.arrival`** tier runs the cheap phases unconditionally (`reattach`, a `work == nil` predicate; `dedupeMemberships` and `dedupePairs`, table fetches that fault nothing) and runs `populateMemberships` / `populateCitations` / `populateDefinitions` / `heal` only where the last `LibraryToleranceScan` counted rows for them — `worksWithoutMembershipCount`, `entriesWithoutCitationBlobCount`, `patternsWithoutDefinitionBlobCount`, three counters added to that walk on the Q58 terms (a scalar read per row on a pass that already walks every table, no relationship faulted). Req 2.7's shape is exactly what those counters see, so an arrival still converges a lagging V7 device's rows; what it no longer pays for is a library that has nothing to convert. -`MembershipReconciler.run(context:, rowsByHostname:, batchSize:, saveStrategy:) -> MembershipReconcileReport` (`healed: [(workID, hostname)]`, `membershipsRemoved`, `pairsRemoved`, `reattached`), logged under the reconciliation log category and counted into the repaired-hostname set, the way `SiteReconciler`'s outcome is (Req 8.1 "report the repair"):+`MembershipReconciler.run(context:, rowsByHostname:, batchSize:, saveStrategy:, heals: Bool = true) -> MembershipReconcileReport` (`healed: [Heal]` — a `workID`/`hostname` struct, not a tuple — `membershipsRemoved`, `pairsRemoved`, `reattached`, and `touchedHostnames`), logged under the reconciliation log category and counted into the repaired-hostname set, the way `SiteReconciler`'s outcome is (Req 8.1 "report the repair"). `heals:` is Decision 5's tier switch and `touchedHostnames` is what step 5 re-validates — every hostname any phase wrote to, whether or not it arrived carrying a diagnosis, because a heal clears a state that is tolerated and therefore never cached: 0. **Re-attach**: a membership with `work == nil` whose `workID` names a Work now present gets `work` set (import- and sync-orphaned rows re-attach the same way). -1. **Heal** (Req 8.1): index memberships by `(workID, hostname)`; walk entries in chunks; for an entry with `work != nil` and no membership for `entry.hostname`, insert one in state `none` with `site` = the winner row.

One insertion per `(work, hostname)` per run, guarded by the index it updates. `createdAt` is the **latest** its Work's memberships already hold, plus one millisecond, falling back to the Work's own `createdAt` where it holds none (Q62 amending Q51). The Work's `createdAt` alone is device-independent but *ties* with the membership a migrated Work already carries, and the tie falls through to two random UUIDs — so a heal became primary half the time, moving Req 6.4's glyph and what the columns mirror. A fixed step off synced content keeps the value device-independent and the order stable.++ The heal runs on the **full** tier only (Decision 5). An arrival-tier pass does not heal a per-hostname miss, so an Entry whose Work holds a membership on another site waits for the next full pass. That is deliberate: the state is tolerated, produces no diagnosis, and the counters the arrival tier gates on cannot see it. 2. **Dedupe memberships** (Req 8.2): group by `(workID, hostname)`; survivor = highest identity state (`rule` > `legacyUnverified` > `none`), then earliest `createdAt`, then lowest `id`; delete the rest. 3. **Dedupe pairs** (Req 5.8): group `WorkDistinctPair` by `(lowerWorkID, higherWorkID)`; keep latest `recordedAt`, then lowest `id`.

One rule serves both paths: a silently-resolvable set has identical hostname sets by construction (Req 5.3), so nothing is ever moved there; the reader-confirmed path can now collapse a set whose members are on different sites (Req 5.2), where deleting would drop a site presence the reader was asked to keep. `WorkDistinctPair` rows naming a loser are rewritten to the survivor (re-sorting the two ids) and deleted when both ends coincide.

Measured against the read paths beside it in+the same run:++| Path | Median | Reads |+|---|---|---|+| `works-snapshot-duplicate-free` | 1.685 s | the whole graph, same fan-out |+| **`merge-destinations`** | **1.319 s** | the whole graph, same fan-out |+| `backup-projection-duplicate-free` | 1.308 s | the whole graph, same fan-out |+| `record-counts-duplicate-free` | 0.322 s | four `enumerate` walks |++The picker is the *cheapest* of the three full projections and sits well inside+the 3 s ceiling that bounds this class of read. A fourth whole-library read path+to keep in step with the other three, bought for a fraction of a second on a+screen the reader reaches deliberately, is not a trade worth making. Recorded+rather than done; revisit if the number ever leaves the class.++### (d) The export projection with `EntryCitationsCache` — confirmed++`backup-projection-duplicate-free` measures **1.308 s** (1.307–1.312 s, n=5)+against the **1.184 s** recorded on 2026-08-09 in+[`../retire-migration-chain/verification-run.md`](../retire-migration-chain/verification-run.md).++The band holds. `EntryCitationsCache` now decodes each Entry's citation blob once+for the whole pass, where three `JSONDecoder` allocations per Entry stood before,+and the projection is +10.5% overall — which is the archive's ten new record+types and the membership records being projected, against a saving on the+decoding.

Every path that reads a+Work now reaches its site presence through a membership row rather than a column,+and the graph carries 1,000 rows it did not carry before. That is the shape of+the feature and it costs about a tenth on the read paths; nothing in that band+left a budget.++### One fixture was stale, not one budget++`reconcile-worst-case-consolidation` **failed** on the first run — twelve issues,+`repinnedRecords → 5000` against an expected 6,000 — and the production code was+right. `M4ConsolidationStore.divert()` pointed 5,000 Entries and 1,000+`Work.site` columns at the loser Site row and counted both back; but since task+21 a Work's site presence is its `WorkSiteMembership`, `SiteReconciler.repin`+walks memberships, and its Work walk is deliberately gone (`Work.site` is unread,+and the one column that walk survived for is not on a V8 membership). The fixture+was diverting a column nothing reads and then asking the reconciler why it had+not moved it.++Fixed in the fixture: the divert and the pin count both go through+`WorkSiteMembership` now. `recordCount` is unchanged at 6,000 — 5,000 Entries+plus 1,000 memberships instead of 1,000 Works — and the measurement came back at+40.754 s against the 40.439 s recorded before, so what the fixture change bought+is the measurement, not a different one.++## 4. Three budgets left their bands++All three are recorded the way `cloudkit-mirroring` recorded its two (Q55) and+`duplicate-reconciliation` its one (Decision 27): the requirement's budget stays+where it is and is asserted **inside** a `withKnownIssue`, a regression ceiling+is asserted **outside** it so a run that drifts into a *new* problem still fails,+and the decision about what to do is left for the design owner. **A breach found+by a measurement task does not authorise taking that decision, and none of these+ceilings was moved to make a run comfortable.**++### 4.1 The arrival debounce: 1.82–2.00 ms → 1.081 s++`reconcile-noop-coherent` is what `reconcileAfterSync` costs over a library with+nothing to reconcile — the overwhelmingly common case, on every remote-change+debounce and once per launch. It is now **~540× its recorded band** and 108× its+10 ms ceiling.++The cause is not subtle. `LibraryRepository.reconcileAfterSync` runs two+whole-library passes in front of everything it already ran+(`LibraryRepository.swift:356-362`), unconditionally and at every tier:++* `V8PopulationPass.run` fetches the whole `Work`, `Entry` and `TitlePattern`+ tables. Its citation phase is a **value** guard by design (Decision 4): it+ re-derives each of the 5,000 Entries' citations from the columns and compares,+ because through task 12's inversion the columns are still the source of truth+ and an existence guard would let a populated blob drift for ever. A converged+ library pays for that comparison on every arrival.+* `MembershipReconciler.run`, whose `heal` phase enumerates the whole Entry+ table. Measured alone at **0.505 s**, which is about half the total.++Both are deliberate. Req 2.7 asks the V8 build to heal what a lagging V7 device+syncs in, and neither state produces a diagnosis a gate could read (Q24) — which+is exactly the argument the duplicate phase's arrival gate can make and this one+cannot.++Nothing here is on an interactive path (Q45 of `cloudkit-mirroring`), so this is+a battery-and-heat question rather than a latency one. The options, none of them+taken here: gate the pass on a counter the way Decision 30 gated the duplicate+phase; make the citation phase an existence guard once task 12 inverts the source+of truth; or accept ~1 s per debounce. **T-2272 is where the citation regime+moves, so the third option may be the cheapest one to hold.**++### 4.2 The duplicate observation pass: 0.93–0.95 s → 2.737 s++Req 10.1's first pass, which was inside its 2 s budget and asserted plainly, is+now 1.37× over it. It times one `reconcileAfterSync`, so about **1.08 s of the+~1.78 s added is 4.1's arrival cost** — roughly 60% of it, with the remainder+being the same two passes doing more than nothing over the 1,350 duplicate rows+this fixture seeds. The settling pass, which times the *second* reconcile in the+same loop, moved with it: 7.264–7.365 s → 9.334 s, still inside its 11 s ceiling+but having spent most of the headroom that ceiling was drawn with.++Recorded as a known issue with a 4 s floor asserted outside it. Most of it is+4.1, and closing 4.1 would bring this back near its budget.++### 4.3 Capture projection: 0.0927–0.1018 s → 0.345–0.356 s++**This is the one that matters most, because unlike the other two it is the path+the reader waits on.** Req 5.4 bounds capture projection — what the share+extension runs — at 100 ms. Every arm now measures ~3.5× that, with a ≤ 1.09×+within-run spread, so it is a measurement and not a noisy run.++`data-model-cleanups` Q18 already had this cell inside a `withKnownIssue`, marked+`isIntermittent` because the `.duplicateIdentity` arm crossed the budget by 1.8%+on some runs while the other two stayed inside it. That is over: no run is going+to meet 100 ms at 0.35 s, so `isIntermittent` is gone, and the 125 ms regression+ceiling has been raised to 450 ms — ~1.27× the worst measured median, the same+proportion 125 ms had to the band it was drawn over.++The cause is nameable. `buildCaptureBasis` reaches the hostname's Works through+`LibraryRepository.worksOn`, which since V8 is:++```swift+internal static func worksOn(hostname: String, context: ModelContext) throws -> [Work] {+ var seen: Set<ObjectIdentifier> = []+ return try membershipsOn(hostname: hostname, context: context)+ .compactMap { seen.insert(ObjectIdentifier($0.work)).inserted ? $0.work : nil }+}+```++— a fetch of the hostname's 1,000 membership rows followed by 1,000 to-one+relationship faults, where a single predicated `Work` fetch stood before. The+`capture-rule-application-*` arms beside it are unchanged at ~0.07 ms, which+places the whole of the cost in the basis build rather than in rule application.++Options, none of them taken here: fetch the Works with a predicate and use the+memberships only to filter; read `membership.workID` and fetch the Works by id in+one round trip; or accept a third of a second on the share sheet. The first two+look cheap, which is a reason to route the decision rather than to make it inside+a measurement task.++## 5. Two runs, not one++The target was run twice. The first run is what found the stale fixture in+[section 3](#one-fixture-was-stale-not-one-budget) — it failed with 24 issues, 12+of them the fixture's — and the second is the record above. Every measurement not+touched by the fixture fix was taken in both, and the two agree closely enough+that the medians can be read as a band:++| Measurement | Run 1 | Run 2 | Δ |+|---|---|---|---|+| `v8-population-pass` | 3.221 s | 3.242 s | 0.7% |+| `membership-reconcile-noop` | 0.506 s | 0.505 s | 0.3% |+| `membership-heal-full` | 2.000 s | 2.011 s | 0.5% |+| `merge-destinations` | 1.331 s | 1.319 s | 0.9% |+| `reconcile-noop-coherent` | 1.080 s | 1.081 s | 0.1% |+| `duplicate-observation-pass` | 2.744 s | 2.737 s | 0.3% |+| `duplicate-settling-pass` | 9.321 s | 9.334 s | 0.1% |+| `backup-projection-duplicate-free` | 1.305 s | 1.308 s | 0.2% |+| `capture-projection-duplicateSiteRows` | 0.354 s | 0.356 s | 0.5% |++A third, earlier run of the new suite alone (before the ceilings were set)+measured `v8-population-pass` at 3.237 s and `merge-destinations` at 1.329 s,+which is the same picture again. That is three consistent readings of the new+paths, and it is still one machine — the caution at the top stands.++## 6. Not run++`make test-performance-m4-recent`, `make install`, `make run` and+`xcrun devicectl` were **not** run, and no agent may run them. Every figure here+is host-only, from a `swift test` of the `AsterismCore` package in release with+`-DASTERISM_PERFORMANCE_TESTING`. Nothing above says anything about what the+shipped app does on a phone.++---++## 7. Review fixes (task 22 review, 2026-08-26)++Two of the three breaches in [section 4](#4-three-budgets-left-their-bands) were+routed back as code changes rather than accepted: the capture-projection+regression (4.3) and the arrival cost behind 4.1 and 4.2. What follows is the+re-measurement, and it is **two further runs** of the same target on the same+host — call them **run 3** (the measurement run, taken with the code fixed and+the *old* ceilings still in place, so nothing about the numbers is a+consequence of moving a bound) and **run 4** (the confirming run, with the+ceilings this section justifies).++Every figure in the table below is run 3's median unless the row says+otherwise; run 4's agreement is recorded in+[7.5](#75-run-4-the-confirming-run).++### 7.1 What changed++* **R1, the capture path.** `LibraryRepository.worksOn` fetched the hostname's+ ~1,000 membership rows and faulted `$0.work` on each, and the basis builders+ downstream then read `work.membershipValues` — a to-many fault per Work — where+ a scalar `siteHostname` column stood before V8. Both are gone.+ `LibraryRepository.hostnameWorks` answers "the Works on this hostname and the+ memberships they hold" in **three predicated fetches and no traversal at all**:+ the hostname's attached memberships, the Works by the `workID` set those name,+ and the memberships of that id set, grouped in memory. The id sets are chunked+ at `bulkOperationBatchSize` because each id is a bound variable and SQLite caps+ those below a thousand. `workBasisEntry` takes its hostnames and+ `identitySnapshot` takes its membership rows, so neither touches+ `work.siteMemberships`. Order is not load-bearing at any of the thirteen+ `worksOn` call sites — every one buckets by application UUID through+ `workGroups` or sorts by `id.uuidString`, and the one that does neither+ (`LibraryRepository+Redirect`) re-sorts into survivor order at the end.+* **R2, the arrival tier.** Decision 5: `LibraryToleranceScan` gained three+ counters, and `reconcileAfterSync`'s `.arrival` tier runs the whole-library+ conversion phases only where one of them is non-zero. The `.full` tier is+ unchanged and unconditional, which is what preserves Decision 4's value guard.++### 7.2 The three breaches, re-measured++| Measurement | Task 22 (run 2) | Review (run 3) | Bound | Verdict |+|---|---|---|---|---|+| `capture-projection-duplicateSiteRows` | 0.356 s | **0.178 s** | 100 ms budget (known issue), 250 ms ceiling | halved, still 1.78× the budget |+| `capture-projection-siteMissing` | 0.345 s | **0.166 s** | as above | halved, still 1.66× |+| `capture-projection-duplicateIdentity` | 0.356 s | **0.177 s** | as above | halved, still 1.77× |+| `reconcile-noop-coherent` (**full** tier) | 1.081 s | **1.073 s** | 10 ms ceiling (known issue), 2 s floor | unchanged, and now by construction |+| **`reconcile-noop-arrival`** (new) | — | **0.030 s** | ≤ ¼ of the full tier, 2 s floor | the tier the debounce runs |+| `duplicate-arrival-pass-gated` | 1.080 s | **0.030 s** | 3 s class ceiling | **36× faster** |+| `duplicate-observation-pass` | 2.737 s | **2.687 s** | 2 s budget (known issue), 4 s ceiling | unchanged: it times a **full**-tier pass |+| `duplicate-settling-pass` | 9.334 s | **9.271 s** | 2 s budget (known issue), 11 s ceiling | unchanged, for the same reason |++**The attribution in [4.1](#41-the-arrival-debounce-1826-ms--108-s) needs+correcting, and this is the correction.** That section read `reconcile-noop-coherent`+as "the arrival debounce". It is not: `reconcileAfterSync()` defaults to `.full`,+and that suite calls it with no tier. What 1.073 s measures is a **full**-tier+pass — which in the app is the launch pass and the duplicate follow-up, neither+of which the reader waits on, and neither of which fires per remote change. The+debounce runs `.arrival` (`AppLibraryModel.handleSyncArrivals`), and the two+labels that actually measure that tier — `reconcile-noop-arrival`, added here,+and `duplicate-arrival-pass-gated`, which existed and was read as an+already-gated number — both sit at **0.030 s** against 1.08 s before the fix.++So `duplicate-observation-pass` did not move, and was never going to: it times+a full-tier `reconcileAfterSync()` through the Req 10.1 fixture. Its breach is+derivative of `reconcile-noop-coherent`'s and closes when that one does, which is+V9 (T-2272) dropping the columns and phase 2 with them. `duplicate-settling-pass`+is worth watching rather than acting on — 9.271 s against an 11 s ceiling is+84% of the headroom that ceiling was drawn with, and the next thing that adds a+second to a settling pass will breach it.++### 7.3 Capture projection: what is left, and why it is not another fan-out++0.166–0.178 s against a 0.0927–0.1018 s pre-V8 band. The two relationship+fan-outs are gone and the remainder is the shape of the V8 basis itself: V7 read+one predicated `Work` fetch and a scalar column, V8 reads three predicated+fetches over ~3,000 rows and resolves a per-Work identity off the membership for+the capture's hostname (Req 3.1). The `capture-rule-application-*` arms beside it+are unchanged at ~0.07 ms, which still places the whole of the cost in the basis+build.++Closing the rest means changing what the basis *is* — projecting the works rather+than materialising them, or narrowing what a capture needs to know about a Work —+not changing how it is read. That is a design decision and it stays routed;+Req 5.4's known issue is kept, with the 450 ms ceiling task 22 drew over a 0.35 s+band brought down to **250 ms**, ~1.4× the worst new median. A little looser than+the 1.23–1.27× the earlier ceilings had to theirs, because those were drawn over+five runs and this over one of a path that has just changed shape.++### 7.4 Ceilings tightened, and one deliberately not++`M4MembershipScalePerformanceTests` drew its ceilings at ~2.5× a *single* run's+band and said in as many words that they should tighten when a second run+widened it. Three runs now agree to within 1%:++| Label | Medians (runs 2, 3, 4) | Old ceiling | New ceiling | Ratio to band |+|---|---|---|---|---|+| `v8-population-pass` | 3.242 / 3.223 / see 7.5 | 8 s | **5 s** | ~1.5× |+| `membership-reconcile-noop` | 0.505 / 0.502 / see 7.5 | 2 s | **800 ms** | ~1.6× |+| `membership-heal-full` | 2.011 / 2.001 / see 7.5 | 5 s | 5 s (kept) | ~2.5× |+| `merge-destinations` | 1.319 / 1.331 / see 7.5 | 3 s | 3 s (kept) | class bound |+| `v7-open-and-migrate` | 0.036 / 0.033 / see 7.5 | 500 ms | 500 ms (kept) | tight absolute, loose ratio |++`membership-heal-full` is **kept loose and relabelled**. It strips every Work's+membership and heals all 1,000 at once, and in production `populateMemberships`+runs first and mints from each Work's retained hostname column — so `heal` only+ever reaches what that could not mint for: a Work with a blank hostname (Q30), or+one whose Entries are on a hostname its memberships are not. The number is an+isolated upper bound on the pass's scaling, not a cost an arrival pays, and a+ceiling drawn tight around it would imply otherwise.++`merge-destinations` is kept at the read-path class ceiling for the reason the+constant already gives: it bounds a class of whole-library read, not this path's+current number. And Q76's own criterion for adding the picker-shaped projection —+"if the measurement comes in over budget" — **could not fire**, because the picker+has no budget; no requirement bounds it.

unticked.
Q100 gave merge and duplicate resolution the deletion gate's introduced-diagnosis semantics: an operation on an already-quarantined hostname commits instead of being refused. Intentional, but a behaviour change.
duplicate-settling-pass sits at 9.3 s of an 11 s ceiling. The next unrelated cost breaks make test-performance-m4 rather than reporting.
The efficiency fixes (validator fan-outs, pair fetch hoist) land after the two recorded make test-performance-m4 runs; expect diagnosis-refresh-* and the settling pass to improve, but the bands in verification-run.md §7 predate them.
