# Pattern Candidate Catalog
This file tracks concepts before promotion into canonical pattern files.
| Candidate | Family | Scale | Status | Main force |
|---|---|---:|---|---|
| Server Authority | authority | L2 | seed | authoritative consistency |
| Local Authority | authority | L2 | seed | offline usability |
| Replicated Authority | authority | L2 | seed | collaborative concurrency |
| URL as Application State | address | L3 | seed | addressability |
| Server Projection | projection | L3 | seed | client compute / delivery |
| Client Projection | projection | L3 | seed | interaction locality |
| Streaming Projection | projection | L3 | seed | first-content latency |
| Islands of Interactivity | projection | L3 | seed | client execution cost |
| Local Interaction State | affordance | L6 | seed | responsiveness |
| Optimistic Overlay | affordance | L6 | seed | interaction latency |
| Invalidate and Reproject | synchronization | L3/L6 | seed | freshness |
| Persistent Subscription | synchronization | L3 | seed | update latency |
| Vertical Feature Slice | composition | L4 | seed | change locality |
| Independent Feature Boundary | composition | L4 | seed | team autonomy |
| Progressive Enhancement | quality | cross-scale | seed | resilience/accessibility |
| Failure Boundary | quality | L5/L6 | seed | fault containment |
`seed` means "worth researching", not "accepted into the canon".
## First investigation dispositions — 2026-09-24
See [AuthorityPilot](../reviews/AuthorityPilot.md). These are manual source-review
outcomes, not successful bench extraction or canonical admission.
| Candidate | Evidence reference | Disposition / question |
| --- | --- | --- |
| Server Authority | SRC-0001, Carniato review C01 | Retain; identify precisely which data and decisions it governs |
| Immediate Feedback | SRC-0001, Carniato review C02 | Add seed; feedback should distinguish tentative from durable/accepted state |
| Local Authority | SRC-0002, local-first review C01 | Retain; test primary ownership versus cache behavior |
| Scoped Authority | Cross-source interpretation in AuthorityPilot | Defer new pattern; may belong in context requirements instead |
No recurrence, established maturity, known uses or required dependency edges are
claimed by these dispositions. Other seed candidates remain unassessed.
2026-09-25: the completed local-first `-06` investigation found no pattern justified
by its single-fragment packet. Local Authority remains a manual seed hypothesis;
no generated candidate IDs or relations were admitted. The missing evidence is
persistence, concurrency, recovery and located independent uses. See
[editorial review](../reviews/TruncationDiagnosis.md).
## Located conflict-handling uses — 2026-09-25
[Conflict Copy](../candidates/ConflictCopy.md) is a new research draft (synchronization,
L2/L6, hypothesis). It merges the Joplin and Obsidian workspace P01 candidates.
Two independently published application guides document the narrow mechanism;
no runtime tests or universal no-loss guarantee. Invalid generated requires edges
were rejected. See [evidence/dispositions](../reviews/LocalFirstEvidenceExpansion.md).
The expanded evidence also refines Local Authority: local persistence, remote-version
selection, semantic resolution and backup are separate concerns. A primary local
copy does not make every local edit globally authoritative.
## Application-driven drafts — 2026-09-25
[VC-02](../walkthroughs/VC02-OfflineFieldNotes.md) connects Conflict Copy with three
new hypothesis research drafts: [Local Commit Boundary](../candidates/LocalCommitBoundary.md),
[Pending Synchronization](../candidates/PendingSynchronization.md), and
[Explicit Reconciliation](../candidates/ExplicitReconciliation.md). Their exact
transaction/retry/UI contracts are proposed, not inferred implementation guarantees.
No FEP IDs or canonical edges. Test whether Explicit Reconciliation deserves a
separate pattern; full admission remains open.
## Transactional expansion — 2026-09-25
Four additional hypothesis drafts: [Local Draft State](../candidates/LocalDraftState.md),
[Version-Checked Mutation](../candidates/VersionCheckedMutation.md),
[Mutation Outcome Tracking](../candidates/MutationOutcomeTracking.md) and
[Invalidate and Reproject](../candidates/InvalidateAndReproject.md).
The last elaborates the existing seed name. Eight developed research drafts now exist;
none has canonical admission. Server Authority remains context; Optimistic Overlay
remains deferred. See [dispositions and evidence](../reviews/TransactionalEvidenceExpansion.md).
## Presentation pilot — 2026-09-26
[Six-pair pilot](../evaluations/language-pilot-01/README.md): initial masked editorial
scoring found 21/24 obligations met with named patterns versus 19/24 with equivalent
prose, and two unsupported claims in each. Inconclusive; human review pending.
Retain all eight hypotheses, no new pattern or promotion. Do not mistake a small
presentation difference for proof of recurrence or improved architecture decisions.
