+## Phase 6A — Library Architecture Decision (2026-10-09 UTC)
+
+**Starting checkpoint:** `34d5394b3ce765028a27b9cddd9952de3f09bfe7`.
+This is a research and decision milestone. It changes no Library implementation,
+content, dependency, route, redirect, publication rule, or deployment file.
+
+### Scope and Method
+
+Inspected the catchall route, all three Library index components,
+`BlogIndexLayout`, `BlogCard`, `BlogPostLayout`, content/author schemas, all blog
+and author records, publication policy/manifest, structured-data author
+resolution, SEO/publication tests, route-audit tooling, Library page records,
+README, migration instructions, accepted reports, and the latest offline route
+reconciliation.
+
+Production `robots.txt` was checked before 29 bounded sequential GETs from
+**2026-10-09 18:01:51–18:02:17 UTC**. Requests covered Library/author roots,
+first-page aliases, representative/last/invalid pages in all three languages,
+trailing-slash examples, `/search`, and one search query. No redirects were
+followed, forms submitted, authentication used, or production writes made. One
+headless Chromium GET verified client-rendered search results.
+
+Responses variously reported HubSpot `HIT`, `MISS`, or `REVALIDATED` and mostly
+October 3–4 prerenders. They establish consistent current public behavior, not
+origin freshness. Historical October 7 observations remain intact and support
+the intervening English page 3–5/author page 3–5 statuses without repeat calls.
+
+### Current Inventory and Confirmed Behavior
+
+- **65 blog records:** 46 English, 12 Spanish, seven Arabic.
+- All 65 are non-draft and generated. Two English syndicated records are
+  accessible `noindex` external-canonical exceptions, leaving **63 sitemap-
+  eligible posts**.
+- Every post has title, description, date, author, category, featured image,
+  canonical, and translation key. Tags are empty on all 65; no post declares
+  `updatedDate` or image-alt frontmatter.
+- Every post uses author slug `rula-diab`. There is one author record per
+  language, all sharing explicit translation key `rula-diab`.
+- Current indexes sort date descending only; stable manifest order implicitly
+  breaks equal dates by route. They render every locale post in one list.
+- English alone has an inert search input. Spanish/Arabic have no search control.
+  No local pagination or author routes exist.
+- The three Library Markdown bodies contain bypassed historical listing
+  snapshots, creating a stale competing representation even though they do not
+  render.
+- Production uses ten posts per page: English 55 posts/six pages, Spanish 12/two,
+  Arabic seven/one. Author archives have the same counts because all posts are
+  currently attributed to Rula Diab.
+- All six `/page/1` Library/author aliases return duplicate 200 content. English
+  trailing-slash examples return 301 to no-slash roots. First invalid page
+  boundaries return 404.
+- Production search is a JavaScript-rendered GET `/search` flow. A browser query
+  for `autism` returned 66 mixed-language blog/listing results, ten per offset
+  page. Raw HTML contains no results and production supplies no useful search
+  canonical/robots/title.
+
+### Architecture Recommendation
+
+Generate one small metadata-only JSON search index per language from a new
+shared Library catalog based on the existing publication manifest. Use a
+dependency-free TypeScript client with Unicode-aware English/Spanish/Arabic
+normalization, weighted deterministic matching, accessible result state, and no
+external query service. Current measured aggregate metadata is 42,090 bytes raw,
+12,693 gzip, or 10,709 Brotli; a raw-body prototype is 474,623/135,796 gzip and
+is not recommended without a verified need.
+
+Use the same catalog for ten-item static Library and author pagination, explicit
+date-descending/route-ascending sorting, author validation, and generated route
+descriptors integrated with the shared publication policy. Page 1 remains each
+root; `/page/1` becomes a locale-specific permanent redirect. Invalid or empty
+pages are not generated. Numbered pages never gain hreflang from matching page
+numbers. Author roots may use explicit author translation keys after localized
+author content is source-reconciled and reviewed.
+
+The complete proposal, alternatives, current evidence, URL disposition matrix,
+route-count model, multilingual/RTL/SEO design, accessibility behavior, Phase 6B
+checkpoints, test matrix, and decision register are in
+[`phase-6a-library-architecture.md`](phase-6a-library-architecture.md).
+
+### Route Implications and Sequencing
+
+With the current corpus, the proposed `/search`, five numbered Library pages,
+three author roots, and five numbered author pages would add 14 HTML routes:
+**96 → 110**. Under the recommended policy, sitemap URLs would be **92 → 105**.
+Validated author-root equivalence would add 12 hreflang links: **174 → 186**.
+Redirect aliases add no HTML routes.
+
+The current corpus can generate only five nonempty English pages. Production
+page 6 and author page 6 contain real distinct content. Phase 6C's nine missing
+English posts must therefore precede final pagination acceptance; no empty page,
+generic-home redirect, or fabricated record is recommended. If all nine are
+ordinary indexable records, the combined upper-bound projection is 121 HTML
+routes and 116 sitemap URLs; exact policy and translation relationships must be
+recomputed from the reconciled records.
+
+### Validation
+
+| Check | Result |
+| --- | --- |
+| Normal `npm run build` | Passed; Astro check 0 errors/warnings/hints; 96 HTML routes |
+| `npm run audit:routes -- --check` | Passed offline against `route-reconciliation-2026-10-09-offline-17-20-21-008Z.json`; no network/writes |
+| Indexing-enabled evidence build | Passed; 96 routes, 92 sitemap URLs, 174 hreflang links across 53 pages |
+| Final normal build | Passed; restored staging output |
+| Final staging safeguards | 96 routes; global `noindex,nofollow`; empty sitemap; no hreflang |
+
+### Decisions Awaiting Approval
+
+1. Metadata-only dependency-free search rather than full-body/Pagefind/client
+   library search.
+2. Ten posts per page and permanent page-1 alias redirects.
+3. Preserved noindex `/search` compatibility for `term`, `q`, legacy `type`, and
+   `offset`, while embedded Library search remains locale-scoped.
+4. Indexable, self-canonical, sitemap-listed numbered/archive pages.
+5. Continued listing/search visibility for the two accessible noindex syndicated
+   pages, preserving current Astro behavior.
+6. Explicit author-root hreflang, optional localized author `displayName`, and
+   source-supported author bio reconciliation with human language review.
+7. Phase 6C content sequencing before English page-6 acceptance.
+
+No functional source file, dependency, route, redirect rule, content record,
+Nix/nginx/deployment configuration, publication policy, or generated application
+behavior was changed in Phase 6A.

+# Phase 6A Library Architecture Proposal
+
+**Decision date:** 2026-10-09 UTC
+**Starting checkpoint:** `34d5394b3ce765028a27b9cddd9952de3f09bfe7`
+**Status:** proposal only; implementation is not authorized
+
+## A. Executive Decision Summary
+
+### Recommended architecture
+
+1. **Search:** generate one compact JSON document index per language from the
+   existing publication manifest and blog collection. Load it on demand and use
+   a small dependency-free TypeScript client for normalization, ranking, result
+   rendering, URL state, and accessibility. Search title, description, headings,
+   category, author display data, and future tags. Do not index full article
+   bodies in the first release.
+2. **Library pagination:** render ten articles per static page, matching the
+   verified production page size. Keep each locale's existing Library root as
+   page 1, generate only nonempty `/page/{n}` pages for `n >= 2`, and permanently
+   redirect `/page/1` aliases to the corresponding root.
+3. **Author archives:** derive localized author pages and their pagination from
+   author records plus the same eligible-post catalog. Generate no manually
+   maintained post lists. Author roots use explicit author `translationKey`
+   relationships; numbered author pages do not become translations merely
+   because their numbers match.
+4. **Routing and policy:** add archive/search descriptors to the shared route and
+   publication model rather than creating a second eligibility system. The
+   existing `[...slug].astro` manifest-driven route architecture should dispatch
+   content and generated archive kinds from one validated static-path inventory.
+5. **Progressive enhancement:** server-rendered paginated Library and author
+   pages remain complete navigation without JavaScript. Search is an explicit
+   enhancement; without JavaScript the search control is not presented as
+   functional and visitors retain normal archive navigation.
+
+This is preferable at the present scale because the three measured metadata
+indexes total **42,090 bytes uncompressed, 12,693 bytes gzip, or 10,709 bytes
+Brotli** for 65 records. English alone is 26,391/8,036/6,652 bytes. A custom
+metadata index keeps queries local, adds no package or service, excludes drafts
+at build time, and can implement Spanish/Arabic normalization explicitly. A
+full-body prototype would be 474,623 bytes uncompressed and 135,796 bytes gzip;
+that additional payload is not justified by a verified visitor requirement.
+
+### Important tradeoffs
+
+- Metadata search will not find a term appearing only in article body copy.
+- Dependency-free ranking will be deterministic and understandable but less
+  sophisticated than fuzzy/stemmed third-party search.
+- Production currently has 55 English articles and six ten-item pages; Astro has
+  46 English records and can create only five nonempty pages. The nine missing
+  Phase 6C articles must be reconciled before English page 6 and author page 6
+  can be accepted. The architecture must not create an empty page or redirect a
+  distinct archive page merely to satisfy a route count.
+- The current localized author records are structurally usable but their names
+  and English-only short descriptions do not reproduce the current Spanish and
+  Arabic archive headings/biographies. Author content needs source-supported
+  reconciliation and human language review before those archives publish.
+
+### Approval gates
+
+Approval is required for the metadata-only search scope, the `/search`
+compatibility behavior, inclusion of accessible noindex syndicated records in
+listings/search, pagination/archive indexing and sitemap treatment, author
+record changes, and sequencing Phase 6C before final English pagination.
+
+## B. Current Architecture Inventory
+
+### Rendering and routing
+
+- `src/pages/[...slug].astro` asks `getPublicationManifest()` for every eligible
+  page/post route and dispatches the three `slug: library` records to separate
+  English, Spanish, and Arabic components. There is no generated archive kind.
+- `LibraryEnglish.astro`, `LibrarySpanish.astro`, and `LibraryArabic.astro` each
+  independently filter the manifest by language, sort by date descending, render
+  every eligible post, and repeat a five-item “popular” slice. English alone
+  renders an inert `<input type="search">`; no script, form, filtering, state, or
+  announcements exist.
+- `BlogIndexLayout.astro` supplies shared hero/intro/sidebar layout and delegates
+  list contents. `BlogCard.astro` creates localized article URLs and dates, but
+  hardcodes Rula Diab's English byline/avatar and does not link to an author
+  archive.
+- `BlogPostLayout.astro` likewise hardcodes the visible English byline. Its
+  BlogPosting JSON-LD independently resolves an exact locale/slug author and
+  already fails for missing or ambiguous records.
+- The three Library Markdown bodies contain old extracted listing snapshots.
+  `[...slug].astro` bypasses these bodies, so they do not render, but they are a
+  competing stale representation. Phase 6B should replace them with maintenance
+  notes only after the generated Library implementation is accepted.
+
+### Publication and translation policy
+
+- `publication.ts` combines page and blog collections and delegates route,
+  canonical, eligibility, sitemap, collision, and translation validation to
+  `publication-policy.ts`.
+- Drafts are not generated. Published noindex and external-canonical records are
+  generated but excluded from the sitemap and hreflang graph. Staging globally
+  emits `noindex,nofollow`, an empty sitemap, and no hreflang.
+- Translation equivalence is explicit and collection-scoped through
+  `translationKey`; it is never guessed from slugs.
+- Authors are intentionally outside the current publication manifest. Author
+  records declare locale and translation keys, but no author routes exist.
+
+### Current content inventory
+
+The historical 65-post count remains accurate, but it was independently
+recalculated from the current files and frontmatter:
+
+| Language | Records | Generated/non-draft | Noindex + external canonical | Sitemap-eligible | Raw Markdown/MDX body bytes |
+| --- | ---: | ---: | ---: | ---: | ---: |
+| English | 46 | 46 | 2 | 44 | 276,099 |
+| Spanish | 12 | 12 | 0 | 12 | 105,272 |
+| Arabic | 7 | 7 | 0 | 7 | 41,832 |
+| **Total** | **65** | **65** | **2** | **63** | **423,203** |
+
+There are no drafts. The two exceptions are
+`community-highlight-meet-rula-diab` and `new-aia-scottsdale-office`; both are
+accessible local English routes with verified `noindex` and external canonicals.
+Current Library components use `eligible`, not `sitemapEligible`, so all 65
+appear in lists.
+
+Every record has title, description, date, author, category, featured image,
+canonical, and translation key. All use category `Library`, all have an empty
+tags array, none has `updatedDate`, and none supplies image `alt` frontmatter.
+The content model can support tags and modification dates later without changing
+the archive algorithm. Search should not pretend empty tags add useful ranking.
+
+Equal-date sets exist in both English and Spanish. Current ordering is date
+descending with an implicit stable route order inherited from the manifest.
+The new catalog should make this explicit: **date descending, then normalized
+route/slug ascending**.
+
+### Author inventory and relationships
+
+| Language | Author records | Author slug | Referencing posts |
+| --- | ---: | --- | ---: |
+| English | 1 | `rula-diab` | 46 |
+| Spanish | 1 | `rula-diab` | 12 |
+| Arabic | 1 | `rula-diab` | 7 |
+
+The three records share `translationKey: rula-diab`, name `Rula Diab`, one
+avatar, and the same short English description. The schema has `name`, `slug`,
+optional `description`, optional `avatar`, `lang`, and `translationKey`. It is
+sufficient to identify and relate archives, but not to reproduce production's
+localized credentialed headings and biographies without content reconciliation.
+An optional locale-specific `displayName` is justified for archive presentation
+while preserving `name` as the person's name in BlogPosting schema. No multiple-
+author field should be added until a real multi-author record requires it.
+
+## C. Production Behavior and URL Evidence
+
+### Method and freshness
+
+`robots.txt` was checked first. It allows the requested public paths. Twenty-nine
+bounded sequential GETs were made from **2026-10-09 18:01:51 through 18:02:17
+UTC** with no-cache request headers, no redirect following, no authentication,
+and no form submission. Requests covered representative roots, first-page
+aliases, last pages, first invalid boundaries, author equivalents, and search.
+One headless Chromium GET then allowed the existing search JavaScript to render
+one result page; it did not submit a form or write to production.
+
+HubSpot responses variously reported `HIT`, `MISS`, or `REVALIDATED` and mostly
+identified October 3–4 prerenders. `Cache-Control: no-store, no-cache,
+must-revalidate` did not establish origin freshness. Findings are current public
+behavior from consistent responses, with potentially cached content. The older
+2026-10-07 route report remains historical evidence for URLs not repeated.
+
+### Observed behavior
+
+| Family | Fresh result | Visible results | Navigation / metadata |
+| --- | --- | ---: | --- |
+| `/library` | 200, `lang=en-us` | 10 | Pages 1–6; page 6 has 5; page 7 is 404 |
+| `/es/library` | 200, `lang=es` | 10 | Pages 1–2; page 2 has 2; page 3 is 404 |
+| `/ar/library` | 200, `lang=ar dir=rtl` | 7 | One page; page 2 is 404 |
+| English author root | 200 | 10 | Pages 1–6; page 6 has 5; page 7 is 404 |
+| Spanish author root | 200 | 10 | Pages 1–2; page 2 has 2; page 3 is 404 |
+| Arabic author root | 200, RTL | 7 | One page; page 2 is 404 |
+
+All six `/page/1` candidates return 200 and show the same ordered article links,
+title, and counts as their root rather than redirecting. English trailing slashes
+on `/library/` and `/library/author/rula-diab/` return 301 to their no-slash
+forms. The inspected archive/listing pages expose no canonical or robots meta;
+their pagination/author URLs are absent from the production sitemap.
+
+The author roots display substantial localized bios and credentialed headings:
+English `Rula Diab, Clinical Director, M.Ed, BCBA, LBA`, a Spanish localized
+equivalent, and an Arabic localized equivalent. These are not represented by
+the current local author records and must not be invented from this report.
+
+### Production search
+
+Library search forms use GET `/search` with `term` plus repeated `type=BLOG_POST`
+and `type=LISTING_PAGE`. The search page's own form uses `q` and also includes
+`SITE_PAGE`. Raw `/search` and `/search?term=autism` HTML contains no results;
+the existing HubSpot JavaScript loads them after page load.
+
+A browser-level GET of
+`/search?term=autism&type=BLOG_POST&type=LISTING_PAGE` displayed **66 mixed-
+language results**, ten per result page, and result offsets `0`, `10`, … `60`.
+The first page included English and Spanish Library roots/posts, confirming that
+production search is global rather than scoped to the Library page's language.
+The search page has no useful document title (raw parsing resolves an SVG title),
+canonical, or robots directive. With JavaScript unavailable, production shows
+no results.
+
+## D. URL Disposition Matrix
+
+`Current` below means the October 9 check; `historical` means the accepted
+October 7 route evidence. Proposed archive pages are self-canonical, indexable,
+and sitemap-eligible under the shared policy. `/search` is noindex and excluded.
+
+| Production URL or pattern | Purpose / language | Evidence and existing behavior | Proposed Astro behavior and preservation | Redirect / canonical / indexing | Phase 6B validation |
+| --- | --- | --- | --- | --- | --- |
+| `/library` | Library page 1, EN | Current 200, 10 results, pages 1–6 | Preserve static page 1 | Self-canonical; index; sitemap; existing EN/ES/AR root hreflang | Generated HTML, canonical, first 10 sorted posts |
+| `/es/library` | Library page 1, ES | Current 200, 10 results, pages 1–2 | Preserve static page 1 | Self-canonical; index; sitemap; existing root hreflang | Locale cards/date/labels and two-page navigation |
+| `/ar/library` | Library page 1, AR | Current 200, 7 results, RTL | Preserve static one-page archive | Self-canonical; index; sitemap; existing root hreflang | `lang=ar dir=rtl`; no nonexistent page 2 |

+
+## E. Search Alternatives and Comparison
+
+| Approach | Quality / languages | Payload and build | Accessibility / privacy | Maintenance | Decision |
+| --- | --- | --- | --- | --- | --- |
+| Generated metadata JSON + custom TypeScript | Explicit field weighting; deterministic Unicode normalization; Spanish accent and Arabic mark handling tested locally; no stemming/fuzzy by default | Current all-language index 42,090 raw / 12,693 gzip; one small client module; ordinary Astro static endpoints | Full control of semantic form/status/focus; queries stay in browser except legacy `/search` URLs; no third party | Small project-owned helper and tests; transparent failure modes | **Recommended** |
+| MiniSearch-style client index | Built-in field boost, prefix, fuzzy matching, suggestions | Adds dependency and serialized index/client code; exact project payload not measured because no package was installed | Local/private and static; UI still project-owned | Better relevance features, but tokenizer/fuzzy behavior needs locale tuning and dependency upkeep | Defer until measured search-quality failures justify it |
+| Pagefind-style post-build search | Indexes rendered pages after Astro, separates indexes by document language, supports static hosting | Adds post-build executable/runtime bundles and tends toward full-page text; changes build/deployment pipeline | Local/private; UI can be accessible but requires integration; no server | Strong general-site search, but broader than this Library and duplicates manifest eligibility/filter work | Reject for current 65-record Library; reconsider for verified site-wide full-text search |
+| External hosted search/API | Potentially strongest ranking/analytics | Network/service dependency and operational credentials | Visitor terms leave the site; logging, consent, retention, failure, and cost concerns | Highest operational burden | Reject under static/data-minimization requirements |
+
+The proposed index stores route, locale, title, description, headings, category,
+future nonempty tags, author display name/slug, and publication date. It excludes
+article body HTML, unpublished content, likes/views, and sensitive or runtime
+data. Featured images need not be duplicated; result cards can use the existing
+article metadata or omit thumbnails in the compact search view.
+
+Normalization should use Unicode NFKC, locale-aware lowercasing, collapsed
+whitespace, and Unicode punctuation separators. A secondary comparison key may
+fold Latin combining marks so `evaluacion` finds `evaluación`, and remove Arabic
+tashkeel/tatweel so marked and unmarked forms match, while preserving original
+display text. Do not apply English stemming to Spanish or Arabic. Rank exact
+title phrase, title tokens, heading matches, description, category/tags, and
+author in that order; break equal scores by date descending then route ascending.
+Prefix matching should require a minimum token length. Empty queries render the
+normal archive; no-result queries announce zero and offer clear/reset.
+
+## F. Pagination and Author Architecture
+
+### Shared catalog
+
+Add a pure `library-catalog` module that accepts the existing publication
+manifest and author records and returns:
+
+- eligible posts grouped by locale;
+- explicit deterministic ordering;
+- ten-item page slices and nonempty page descriptors;
+- exact locale/slug author resolution with duplicate/missing validation;
+- author archive descriptors derived from post relationships;
+- compact locale search records.
+
+It must not read extracted Library Markdown listing bodies or maintain manual
+post arrays. Current accessible noindex/external-canonical posts remain listable
+because that is established behavior, while drafts remain absent. An author
+archive should require a valid locale author record and at least one eligible
+post, including at least one sitemap-eligible post before the archive itself can
+be indexable.
+
+### Static route generation
+
+Extend the manifest-driven static-path inventory with validated generated route
+descriptors (`library-page`, `author-index`, `author-page`, `search`) and run
+their canonical, collision, robots, and sitemap state through reusable Phase 3A
+policy functions. Do not hand-author content records for numbered pages. The
+catchall renderer can dispatch descriptor kinds to shared Library/archive
+components while preserving content routes and collision detection.
+
+Page 1 is always the unnumbered root. Next/previous and numbered links are real
+anchors with localized accessible labels, `aria-current="page"` on the current
+page, and no links to nonexistent pages. Invalid numbers, zero, negative values,
+nonintegers, unknown author slugs, authors with no eligible posts, and pages past
+the end produce no static route and therefore 404.
+
+Search temporarily replaces the visible page list with all-language-appropriate
+matching results and hides the archive pager; clear/reset restores the original
+server-rendered page. Adding, removing, drafting, or changing an article updates
+search and page chunks in one build without manual index edits.
+
+### Author presentation
+
+Resolve the author once by exact locale and slug. Reuse the same resolution in
+BlogCard, BlogPostLayout, BlogPosting schema, and author archives. Add an optional
+locale-specific `displayName` only to preserve the published credentialed archive
+heading; retain `name` for the Person entity. The existing description/avatar can
+drive the bio after source reconciliation. Build must fail on missing or duplicate
+locale/slug records. Do not treat authors as team members or infer employment.
+
+### Route-count model
+
+With the current 46/12/7 corpus and ten items per page:
+
+| Addition | HTML routes | Sitemap URLs | Hreflang links |
+| --- | ---: | ---: | ---: |
+| `/search` | +1 | 0 | 0 |
+| Library pages 2+ (4 EN, 1 ES) | +5 | +5 | 0 |
+| Three author roots | +3 | +3 | +12 if explicit author equivalence is approved |
+| Author pages 2+ (4 EN, 1 ES) | +5 | +5 | 0 |
+| **Projected current total** | **96 + 14 = 110** | **92 + 13 = 105** | **174 + 12 = 186** |
+
+This current-corpus model intentionally lacks the two distinct English page-6
+routes. If all nine Phase 6C English posts are ordinary eligible/indexable
+records, those posts add nine HTML/sitemap URLs and produce one more Library and
+one more author page. The combined projection becomes **121 HTML routes** and
+**up to 116 sitemap URLs**. Exact counts must be recalculated from final policy;
+new translation relationships could separately affect hreflang.
+
+## G. Multilingual and SEO Design
+
+- Each JSON index contains one locale only. Embedded Library search never mixes
+  languages. The `/search` compatibility page may search all locales but must
+  expose an explicit locale filter and label result language.
+- Components receive localized labels/messages; none are generated by machine
+  translation. Missing copy blocks implementation for that locale rather than
+  falling back silently to English.
+- Arabic uses the existing `lang=ar dir=rtl` layout. Pagination order, arrows,
+  search icon placement, result counts, focus order, and mixed Latin/Arabic text
+  require RTL browser testing. Use `Intl.DateTimeFormat`/`Intl.NumberFormat` with
+  the page locale; keep machine-readable dates stable.
+- Existing Library roots retain their explicit three-language translation set.
+  Numbered pages do not receive hreflang because page N contains different
+  records across locales.
+- Author roots may participate only through the author collection's explicit,
+  validated `translationKey`, with reciprocal published archives and English as
+  `x-default`. Numbered author pages receive no hreflang.
+- `/search` has no translation graph and is noindex. JSON endpoints and redirect
+  sources never enter the sitemap.
+- Generated archive pages self-canonicalize to normalized local URLs and use the
+  staging/production robots switch. Page 2+ and author archives are recommended
+  as indexable and sitemap-eligible to remain consistent with Phase 3A's “all
+  eligible self-canonical local routes” rule. This intentionally improves on
+  production's missing canonicals and sitemap omission and requires approval.
+- LanguageSwitcher uses only the validated graph. It must not construct page-N,
+  author, or search equivalents from route shape.
+
+## H. Accessibility and Progressive Enhancement
+
+- Render complete cards and archive pagination on the server.
+- Hide/reveal the enhanced search form only after its script initializes; include
+  a `<noscript>` explanation and links to the three Library roots. Do not show a
+  control that appears functional when JavaScript is unavailable.
+- Use an explicit label, native search input, submit button, and clear button.
+  Preserve browser keyboard behavior; Escape may clear only when documented and
+  must not trap focus.
+- Announce result counts/no-results through a persistent `aria-live="polite"`
+  status. Do not announce on every keystroke without debouncing.
+- Keep focus in the input while typing. On explicit submission, move focus to a
+  results heading only when that improves navigation; clearing returns to the
+  input and restores the original archive.
+- Use real result links and real pagination anchors. Mark current page with
+  `aria-current`; give previous/next localized accessible names; maintain visible
+  focus indication and adequate touch targets.
+- New embedded searches should store state in a URL fragment to avoid sending
+  terms to the static server while retaining share/back-forward behavior. The
+  legacy `/search?term=` compatibility route necessarily sends its query and
+  should document that static-host access logs may retain it.
+
+## I. Performance and Deployment
+
+Expected static output is three JSON files such as
+`/assets/search/library-en.json`, `library-es.json`, and `library-ar.json`, one
+compiled client module, the generated HTML archives, and redirect-map entries.
+Load only the current locale index on first interaction; `/search` can load the
+selected locale and additional indexes only when requested. Cache fingerprinted
+client code immutably and JSON with normal deploy revalidation so new posts are
+visible after a release.
+
+No database, persistent process, server-side search, external query service,
+environment variable, or production API is required. The result works on nginx,
+the current Nix environment, a Raspberry Pi serving static files, the existing
+VPS, and conventional static hosts. Build cost is a small pass over content and
+JSON serialization. Redirect behavior remains a deployment concern and must be
+validated against the selected host; Phase 6A changes no nginx/Nix/deployment
+file.
+
+## J. Proposed Phase 6B Implementation Checkpoints
+
+### 6B.1 — Shared catalog and search assets
+
+- **Likely files:** new `src/utils/library-catalog.ts`; JSON endpoint(s);
+  `LibrarySearch.astro` and client script; existing Library components/layout;
+  tests and README/report.
+- **Work:** derive eligible locale catalogs, explicit sort, metadata-only index,
+  normalization/ranking, locale messages, embedded search, and `/search`
+  compatibility route. Replace inert English input; add Spanish/Arabic controls.
+- **Dependencies:** approval of search fields, legacy route behavior, and
+  noindex-record inclusion. No package dependency recommended.
+- **Acceptance:** all search cases pass; JSON contains no drafts/body; current
+  route count increases by one for `/search`; search remains noindex/out of
+  sitemap; normal Library works without JavaScript.
+- **Validation:** `test:library`, SEO/publication suites, both builds, route/link
+  audits, browser keyboard/RTL/JS-disabled checks.
+
+### 6B.2 — Library pagination and first-page redirects
+
+- **Likely files:** catalog helper, route manifest/catchall dispatch, shared
+  Library renderer/pager, redirect generator/map, tests/reports.
+- **Work:** ten-item chunks, page 2+ descriptors, root page 1, invalid-page 404,
+  six page-1 redirects, localized pagination. Remove bypassed listing snapshots
+  from the three Library bodies only after rendered acceptance.
+- **Prerequisite:** Phase 6C must supply the nine missing English records before
+  `/library/page/6` can pass preservation acceptance. If Phase 6C is not ready,
+  stop this checkpoint with five English pages rather than fabricating content.
+- **Acceptance:** every page has unique real content, explicit sort, valid
+  canonicals/robots/sitemap state, no empty pages, and production URLs through
+  current last pages.
+
+### 6B.3 — Author model, archive roots, and byline links
+
+- **Likely files:** author schema/records, catalog/route descriptors, new author
+  archive presentation, BlogCard, BlogPostLayout, structured-data resolution
+  helper, tests/report.
+- **Work:** optional `displayName`, source-supported localized bios/headings,
+  exact locale/slug resolution, archive pages/pagination, and shared linked
+  bylines. Preserve BlogPosting attribution semantics.
+- **Dependencies:** source reconciliation and human Spanish/Arabic review;
+  approval of author-root hreflang and sitemap policy.
+- **Acceptance:** roots and all nonempty numbered routes resolve; missing,
+  duplicate, zero-post, and invalid authors fail/404 appropriately; no manual
+  article arrays; no employment claims.
+
+### 6B.4 — URL and SEO reconciliation
+
+- **Likely files:** existing redirect generation/report outputs, publication
+  tests, route-audit evidence; no hosting config until separately authorized.
+- **Work:** add exact page-1/trailing normalization decisions, verify canonical,
+  robots, sitemap, collisions, invalid boundaries, search noindex, and preserve
+  all known paths.
+- **Acceptance:** disposition matrix is executable and audited; no redirect to a
+  generic Library root for a distinct page 2+ URL; staging safeguards remain.
+
+### 6B.5 — Multilingual, accessibility, and performance acceptance
+
+- **Likely files:** focused tests/report and only defect fixes in approved
+  components.
+- **Work:** English/Spanish/Arabic search, localized counts/dates, RTL pager,
+  screen-reader announcements, keyboard/focus, JS-off browse, payload checks,
+  mobile/desktop browser review.
+- **Acceptance:** no fabricated translation routes; index sizes recorded; no
+  external query transmission; complete build/audit matrix passes.
+
+Each checkpoint must be an isolated reviewable diff. Failed validation stops the
+sequence. Phase 6C content changes should remain a separate checkpoint even if
+they are scheduled between 6B.1 and 6B.2.
+

+
+## L. Human-decision Register
+
+### Established project policy
+
+- Static Astro, Markdown/MDX content collections, TypeScript, Zod, no database or
+  headless CMS, no form/search backend, and no invented translations.
+- Publication eligibility, canonicals, robots, sitemap, explicit translation
+  relationships, staging protection, and external-canonical exceptions remain
+  governed by Phases 3A/3B.
+- Search, pagination, and author archives are required visitor capabilities;
+  HubSpot internals need not be copied.
+
+### Codex recommendations requiring approval
+
+1. Approve dependency-free generated metadata JSON search and defer full-body,
+   fuzzy, and stemmed search until measured failures justify them.
+2. Approve ten posts per page, unnumbered page-1 canonicals, and locale-specific
+   301 redirects from all six `/page/1` aliases.
+3. Approve `/search` as a preserved noindex compatibility page accepting `term`,
+   `q`, legacy `type`, and `offset`; embedded Library search remains locale-only.
+4. Approve indexable, self-canonical, sitemap-listed page 2+ and author archives,
+   even though HubSpot omits those URLs from its sitemap and canonical markup.
+5. Approve retaining accessible noindex/external-canonical articles in lists and
+   internal search, matching current Astro behavior; they remain excluded from
+   sitemap/hreflang and preserve their metadata.
+6. Approve explicit author-root hreflang from author `translationKey`, with no
+   hreflang for numbered pages.
+7. Approve an optional localized `displayName` author field and a separate
+   source-supported author-content reconciliation with human Spanish/Arabic
+   review.
+8. Approve scheduling the nine-post Phase 6C reconciliation before pagination
+   and author page-6 acceptance. No empty or misleading page 6 should ship.
+
+### Not yet verified or intentionally deferred
+
+- Production-cache timestamps do not prove origin freshness.
+- Search query frequency and the value of body-only/fuzzy matching have not been
+  measured; no analytics should be added to answer this without consent review.
+- Exact hosting redirect syntax remains undecided and must be validated for the
+  selected deployment target.
+- Current author records are not adequate evidence for localized biography copy.
+- Phase 6C publication/indexing/translation status for the nine missing posts is
+  unknown, so the post-6C route projection is an upper-bound model.
+
+No Phase 6B implementation, dependency installation, redirect, content edit, or
+deployment change is authorized by this proposal.
