Queued does not mean reviewed. Bibliography and hashes live in each workspace's source artifact and manifest. Preparation review records selection, provenance limits and remaining work. Claim IDs will resolve inside completed source reviews; preparation packets do not establish a pattern.

Catalog policy

Each source should eventually capture:

• source identity,
• date/version,
• scope,
• vocabulary used,
• candidate patterns,
• dominant forces,
• assumptions,
• contradictions,
• known implementations,
• evidence quality.

2026-09-24: initial authority-focused reviews are recorded as extracted. They have not passed a full-source or independent review gate. Live calls failed before any artifact generation. See AuthorityPilot for findings, execution evidence and limitations.

2026-09-25: local-first -06 completed after replacing padded claim tables with compact records. Its bounded negative result does not complete full-source review. Source state remains extracted; recurrence and independent implementations remain open.

Pinned frontend implementations — 2026-09-25

SRC-0013 Zulip, SRC-0014 Element Web, SRC-0015 Matrix JS SDK and SRC-0016 Matrix client-server specification v1.15 are inspected in the frontend recovery review. The manifest records exact revisions, file URLs and SHA-256 hashes. State: bounded static review; no runtime validation. Element and its SDK are one implementation family. Complete-pattern recurrence remains unproven despite two partial draft-preservation uses.

Executable SDK follow-up — 2026-09-25

SRC-0017: published matrix-js-sdk 42.3.0; npm archive and integrity recorded in experiment provenance. State: executed under controlled synthetic transport. Four cases pass; server guarantees remain assumptions. This is the SRC-0014/0015 implementation family, not another independent application. Review.

Navigation/rendering documents — 2026-09-26

ID	Primary source	Scope / state
SRC-0018	htmx documentation	History and representation caching; bounded documentary review
SRC-0019	htmx hx-boost	Native link/form enhancement; same publisher family as SRC-0018
SRC-0020	SvelteKit form actions	Native forms and scoped use:enhance contract
SRC-0021	SvelteKit page options	Initial HTML and optional client execution; same family as SRC-0020
SRC-0022	MDN History.pushState	Browser history API; not an application known use

Living pages accessed 2026-09-26, exact revisions unknown; no runtime checks. Claim locators, dispositions and limits.

Presentation, composition and quality expansion — 2026-09-26

ID	Primary source	Scope / revision
SRC-0023	Fowler: Presentation Model	2004-07-19 historical draft; presentation/view synchronization
SRC-0024	Redux: Deriving Data with Selectors	Minimal stored state and computed views
SRC-0025	FSD slices/segments	Pinned revision 6691676119fc998b6d58a2b32582c0074a072f2d; product grouping and public interfaces
SRC-0026	Astro islands	Client activation boundaries
SRC-0027	React Component	Rendering-error fallback and exclusions
SRC-0028	WAI APG modal dialog	Focus entry/return and exceptions

All accessed 2026-09-26; exact revisions unknown unless stated. Bounded documentary review, no runtime or deployment validation. Claims B01–B06 and dispositions. These sources address different mechanisms and do not establish independent recurrence of any one complete candidate.

Browser boundary execution — 2026-09-26

SRC-0029: React 19.3.0 / React DOM 19.3.0 and Radix Dialog 1.1.23, with pinned transitive dependencies and inspected published modules. Provenance and lockfile identify archives/integrity; synthetic Chromium fixture, not a deployed application. One mechanism study, not independent full-pattern recurrence.

SRC-0030: Radix Dialog documentation, Content API and keyboard interaction; living page accessed 2026-09-26, revision unknown. Displayed documentation version differs from executed package; runtime claims use the pinned archive, not an assumption that the page exactly matches it. Results and limits.

SRC-0029 follow-up: nested dismissal isolation reuses the same pinned packages across two browsers/build modes. Instrumented and experimentally modified bundles are explicitly separated from the unmodified control; this is additional evidence from the same family, not a new independent use.

SRC-0029 further follow-up: experimental ownership routing compares unchanged packages with an explicitly modified in-memory Escape mechanism. The routed results are evidence for our proposed design, not observations of shipped vendor behavior. Current raw control also reproduces production wrong-owner dismissal in the new controlled fixture. Prior receipts remain unchanged.

Feature organization and release contrast — 2026-09-26

ID	Source	Revision / evidence scope
SRC-0031	FSD todo example	3050d1080506823df79c77457b96b47a835f87c8; feature interfaces and application build
SRC-0032	React microfrontends root-config	b5414dcf7b4ecda95f11ada3821e30d2acfd9e4e; composition and workflow
SRC-0033	React microfrontends navbar	55ff88e74714d12d3e3447250e34a2b7742e91f6; lifecycle and workflow, same family as SRC-0032
SRC-0034	single-spa recommended setup	Living 6.x documentation; runtime binding and deployment contracts
SRC-0035	webpack Module Federation	Living documentation; separately built containers and shared dependencies

Accessed 2026-09-26. 17-file hash manifest and claims D01–D09. Static example-source inspection, no builds or deployments run. Documentation revisions unknown; examples and docs do not establish independent recurrence of a complete release contract.

Native-module release experiment — 2026-09-26

SRC-0036: feature release fixture, authored synthetic host/artifacts with locked Playwright and hashed browser/input provenance. Seven cases in Chromium/Firefox, 14/14 expected observations. Distinct from the earlier pinned source examples; no deployed release workflow was executed.

SRC-0037: MDN dynamic import, Module namespace object; living documentation accessed 2026-09-26, exact revision unknown. Context for evaluated module reuse versus HTTP caching. Review.

SRC-0036 follow-up: activation conflicts and update reload adds an authored conditional-write server and reload policy with sessionStorage. Three HTTP cases plus nine cases per browser, 21/21 expected observations; negative controls included. Same synthetic evidence family, not an independently deployed use.

Prospective navigation runtime — 2026-09-27

SRC-0038: navigation/history fixture, htmx 2.0.11 and Playwright 1.63.0 with locked packages and hashed inputs/browser binaries. Authored HTTP application; 18 browser cases plus explicit HTTP validator sequence repeated twice. NH01–NH06 review, preregistered prospective corroboration. This is one implementation family, not an independent production deployment. Initial launch failure receipt preserved.

Navigation focus and feedback — 2026-09-27

SRC-0038 follow-up: NF01–NF06, separate focus runner and authored policy using the same pinned htmx fixture family. 22 registered keyboard/DOM rows; not assistive-technology validation or independent use.

SRC-0039: W3C Understanding Focus Order and Status Messages, primary interpretive guidance accessed 2026-09-27; living revision unknown. One W3C family, not two application uses. NF review limits the inference to meaningful focus order and programmatically exposed feedback; no conformance claim from this fixture.

SRC-0040: htmx events, lifecycle-hook reference accessed 2026-09-27, living revision unknown. Same htmx family as SRC-0018/0019 and SRC-0038. Runtime conclusions use pinned 2.0.11 code and hashed receipts.

SRC-0038 ownership follow-up, 2026-09-27: NO01–NO06 compares the unchanged prior focus policy with an authored generation/focus guard. 24 completed rows, guard 12/12 full obligations versus baseline 0/12, with initial keyboard-helper failures retained. Same fixture family and pinned htmx package. SRC-0040 event documentation and pinned loadHistoryFromServer source delimit the experimental history-XHR adapter; no vendor patch or production claim.
