Session Start **Environment verified**: * [x] Prerequisites confirmed * [x] Tools available * [x] Directory structure ready * [x] Package context resolved to `public-website` *** ### Task T001 - Verify Phase 13 prerequisites, Node PATH, and metadata placeholder evidence **Started**: 2026-06-01 17:19 **Completed**: 2026-06-01 17:20 **Duration**: 1 minute **Notes**: * Ran the apex spec analysis script and confirmed current session `phase13-session03-seo-metadata-and-static-site-plumbing`. * Ran package prereq checks for `public-website`; all required environment checks passed. * Confirmed default shell resolves Node 24.14.0/npm 10.5.1, so validation commands must prepend `/home/aiwithapex/.nvm/versions/node/v26.2.0/bin` to satisfy the session baseline. * Verified `BaseLayout.astro` contains the Session 03 metadata placeholder for Open Graph, Twitter, RSS, robots, and structured metadata. **Files Changed**: * `.spec_system/specs/phase13-session03-seo-metadata-and-static-site-plumbing/implementation-notes.md` - Created session log and recorded setup verification. **BQC Fixes**: * N/A - setup verification only. *** ### Task T002 - Inspect current Astro static config, RSS dependency, and sitemap integration posture **Started**: 2026-06-01 17:20 **Completed**: 2026-06-01 17:21 **Duration**: 1 minute **Notes**: * Confirmed `astro.config.mjs` sets `site: "https://faction-os.com"`, `output: "static"`, and includes the MDX and sitemap integrations. * Confirmed `@astrojs/rss` is present in `public-website/package.json`; no dependency change is required for the RSS route. * No server adapter, analytics package, CMS adapter, React, Tailwind, or runtime behavior was present or added. **Files Changed**: * `.spec_system/specs/phase13-session03-seo-metadata-and-static-site-plumbing/implementation-notes.md` - Recorded the static config inspection. **BQC Fixes**: * N/A - inspection only. *** ### Task T003 - Create SEO component and helper directories **Started**: 2026-06-01 17:21 **Completed**: 2026-06-01 17:21 **Duration**: 1 minute **Notes**: * Created the SEO component directory and metadata helper directory for this session's deliverables. * Kept changes scoped inside `public-website`. **Files Changed**: * `public-website/src/components/seo/` - Created directory for SEO components. * `public-website/src/lib/` - Created directory for metadata helpers. **BQC Fixes**: * N/A - directory setup only. *** ### Task T004 - Create central site configuration **Started**: 2026-06-01 17:22 **Completed**: 2026-06-01 17:23 **Duration**: 1 minute **Notes**: * Added typed site identity, route, destination, contact, metadata default, and structured-data seed configuration. * Kept the temporary social image fallback on the existing reviewed favicon instead of promoting unreviewed brand media. * Updated navigation destinations to read demo and docs URLs from the central site config. **Files Changed**: * `public-website/src/data/site.ts` - Created central site configuration and conservative structured-data seeds. * `public-website/src/data/navigation.ts` - Reused central external destination URLs and labels. **BQC Fixes**: * Contract alignment: Centralized destination values so navigation and metadata use the same public URL contract. * Trust boundary enforcement: Structured data exposes only public labels and URLs. *** ### Task T005 - Create canonical URL and robots helpers **Started**: 2026-06-01 17:23 **Completed**: 2026-06-01 17:24 **Duration**: 1 minute **Notes**: * Added URL helpers for normalized paths, absolute site URLs, canonical URLs, social asset URLs, and RSS/manifest/favicon URL resolution. * Added robots policy helpers that support default index/follow, explicit noindex/nofollow, and optional crawler limits. * Added page metadata resolution so `Seo.astro` can consume one normalized metadata object. **Files Changed**: * `public-website/src/lib/metadata.ts` - Created canonical URL, robots, title, and metadata resolution helpers. **BQC Fixes**: * Contract alignment: Centralized canonical and robots string generation to avoid contradictory route-level metadata. * Failure path completeness: Empty metadata inputs fall back to safe defaults instead of emitting blank crawler fields. *** ### Task T006 - Create JSON-LD component **Started**: 2026-06-01 17:24 **Completed**: 2026-06-01 17:25 **Duration**: 1 minute **Notes**: * Added a reusable JSON-LD Astro component that accepts the typed structured-data payload union from `site.ts`. * Added runtime validation for supported schema.org payload types before outputting inline JSON. * Escaped `<` characters in serialized JSON to keep inline script output safe. **Files Changed**: * `public-website/src/components/seo/JsonLd.astro` - Created typed JSON-LD rendering component. **BQC Fixes**: * Trust boundary enforcement: Runtime payload validation prevents unsupported structured-data shapes from being emitted. * Error information boundaries: Invalid payload errors are stable and do not expose local paths, tokens, or raw payload content. *** ### Task T007 - Create SEO component **Started**: 2026-06-01 17:25 **Completed**: 2026-06-01 17:26 **Duration**: 1 minute **Notes**: * Added `Seo.astro` to emit default and override metadata for descriptions, robots, canonical URLs, Open Graph, Twitter cards, RSS discovery, manifest, favicon, and JSON-LD. * Wired the component to central site defaults and metadata helpers rather than duplicating URL or title logic. * Kept structured data conservative and disableable per page through `structuredData={false}` if needed later. **Files Changed**: * `public-website/src/components/seo/Seo.astro` - Created reusable SEO metadata component. * `public-website/src/components/seo/JsonLd.astro` - Allowed readonly structured-data arrays from central site config. **BQC Fixes**: * Contract alignment: All emitted metadata is resolved from a single helper output. * Failure path completeness: Missing page metadata falls back to site defaults. *** ### Task T008 - Wire BaseLayout to SEO component **Started**: 2026-06-01 17:26 **Completed**: 2026-06-01 17:27 **Duration**: 1 minute **Notes**: * Replaced route-local placeholder head tags in `BaseLayout.astro` with `Seo.astro`. * Preserved layout-owned charset, viewport, body class, and noindex pass-through behavior. * Exposed canonical, robots, social, Open Graph, and structured-data props for downstream layouts and pages. **Files Changed**: * `public-website/src/layouts/BaseLayout.astro` - Delegated document metadata to `Seo.astro`. **BQC Fixes**: * Contract alignment: Removed duplicated title, description, canonical, favicon, and robots rendering from the base layout. * State freshness on re-entry: Each route render resolves metadata from current props and defaults rather than retained layout-local constants. *** ### Task T009 - Pass metadata props through content layout **Started**: 2026-06-01 17:27 **Completed**: 2026-06-01 17:27 **Duration**: 1 minute **Notes**: * Added canonical, robots, noindex, Open Graph, social, and structured-data pass-through props to `ContentLayout.astro`. * Defaulted canonical path to the active route path when a content page does not provide a specific override. **Files Changed**: * `public-website/src/layouts/ContentLayout.astro` - Passed content page metadata intent to `BaseLayout`. **BQC Fixes**: * Contract alignment: Content pages now share the same metadata prop contract as the base layout. *** ### Task T010 - Pass legal noindex and metadata overrides through legal layout **Started**: 2026-06-01 17:27 **Completed**: 2026-06-01 17:28 **Duration**: 1 minute **Notes**: * Added canonical, robots, noindex, Open Graph, social, and structured-data pass-through props to `LegalLayout.astro`. * Preserved legal layout default `noindex` behavior and the existing static review boundary copy. * Did not add hosted policy acceptance, forms, analytics, or account workflow claims. **Files Changed**: * `public-website/src/layouts/LegalLayout.astro` - Passed legal page metadata intent to `BaseLayout`. **BQC Fixes**: * Contract alignment: Legal pages now use the shared metadata prop contract while keeping their noindex default. * Error information boundaries: No legal acceptance or hosted workflow metadata claims were introduced. *** ### Task T011 - Add robots file **Started**: 2026-06-01 17:28 **Completed**: 2026-06-01 17:28 **Duration**: 1 minute **Notes**: * Added a static `robots.txt` that allows normal crawl and references the sitemap index. * Avoided private or non-existent route rules. **Files Changed**: * `public-website/public/robots.txt` - Created crawl policy and sitemap pointer. **BQC Fixes**: * Contract alignment: Robots file sitemap URL matches the configured canonical origin. *** ### Task T012 - Add web manifest **Started**: 2026-06-01 17:28 **Completed**: 2026-06-01 17:29 **Duration**: 1 minute **Notes**: * Added a static manifest with site identity, theme colors, browser display posture, and existing favicon icon reference. * Avoided service-worker, install prompt, or runtime PWA claims. **Files Changed**: * `public-website/public/site.webmanifest` - Created static website manifest. **BQC Fixes**: * Contract alignment: Manifest identity and favicon path match the central metadata defaults. *** ### Task T013 - Verify and refine favicon SVG metadata **Started**: 2026-06-01 17:29 **Completed**: 2026-06-01 17:29 **Duration**: 1 minute **Notes**: * Verified the existing favicon is an owned static asset already present in `public-website/public`. * Added explicit SVG title metadata and `aria-labelledby` while leaving the artwork unchanged. * Did not promote or reference any unreviewed brand media. **Files Changed**: * `public-website/public/favicon.svg` - Added accessible title metadata. **BQC Fixes**: * Accessibility and platform compliance: Favicon SVG now has a stable title reference for SVG consumers. *** ### Task T014 - Add RSS route foundation **Started**: 2026-06-01 17:29 **Completed**: 2026-06-01 17:30 **Duration**: 1 minute **Notes**: * Added an Astro RSS route at `rss.xml.js` using the existing `@astrojs/rss` dependency. * Emits a valid empty feed until Session 04 adds content collections. * Left an explicit integration note that future feed items must come from non-draft content only. **Files Changed**: * `public-website/src/pages/rss.xml.js` - Created static RSS feed route scaffold. **BQC Fixes**: * Contract alignment: RSS title, description, and site URL read from central site config. * Failure path completeness: Empty content collections still produce a valid feed instead of a missing route. *** ### Task T015 - Update homepage metadata inputs **Started**: 2026-06-01 17:30 **Completed**: 2026-06-01 17:30 **Duration**: 1 minute **Notes**: * Updated the homepage to use central site metadata defaults for title and description. * Passed an explicit homepage canonical path and social metadata inputs into `BaseLayout`. * Reused central external destination definitions for demo and docs CTA links while preserving their accessible labels. **Files Changed**: * `public-website/src/pages/index.astro` - Replaced duplicated metadata and external URL constants with central site config. **BQC Fixes**: * Contract alignment: Homepage metadata and CTA destinations now use central site config. * Accessibility and platform compliance: External CTA aria labels remain attached to the button links. *** ### Task T016 - Verify Astro static output and package posture **Started**: 2026-06-01 17:30 **Completed**: 2026-06-01 17:30 **Duration**: 1 minute **Notes**: * Rechecked `astro.config.mjs`; it still sets `site: "https://faction-os.com"`, `output: "static"`, and MDX plus sitemap integrations. * Confirmed `@astrojs/rss`, `@astrojs/sitemap`, `@astrojs/mdx`, and `astro` remain present in `public-website/package.json`. * Searched the website package for server adapters, analytics packages, React, Tailwind, shadcn, and CMS package/config references; matches were only existing no-claim copy, not dependencies or runtime wiring. **Files Changed**: * `.spec_system/specs/phase13-session03-seo-metadata-and-static-site-plumbing/implementation-notes.md` - Recorded posture verification. **BQC Fixes**: * N/A - configuration verification only. *** ### Task T017 - Run package typecheck **Started**: 2026-06-01 17:29 **Completed**: 2026-06-01 17:30 **Duration**: 1 minute **Notes**: * Ran `PATH=/home/aiwithapex/.nvm/versions/node/v26.2.0/bin:$PATH npm --prefix public-website run typecheck`. * The first run found a narrow literal type inference in `formatPageTitle`; widened the parameter to `string`. * Reran typecheck successfully with Node 26.2.0/npm 11.16.0. **Files Changed**: * `public-website/src/lib/metadata.ts` - Widened `formatPageTitle` input typing after typecheck failure. * `.spec_system/specs/phase13-session03-seo-metadata-and-static-site-plumbing/implementation-notes.md` - Recorded typecheck evidence. **BQC Fixes**: * Contract alignment: Typecheck confirmed the metadata helper accepts route-specific title strings, not only the default literal title. *** ### Task T018 - Run package build and inspect generated artifacts **Started**: 2026-06-01 17:30 **Completed**: 2026-06-01 17:31 **Duration**: 1 minute **Notes**: * Ran `PATH=/home/aiwithapex/.nvm/versions/node/v26.2.0/bin:$PATH npm --prefix public-website run build`. * The build completed successfully and emitted `/rss.xml`, `/index.html`, sitemap files, `robots.txt`, `site.webmanifest`, and `favicon.svg`. * Inspected generated homepage metadata and confirmed canonical URL, description, robots, Open Graph, Twitter, RSS discovery, manifest link, favicon link, and JSON-LD output. * Inspected generated RSS, robots, manifest, and sitemap artifacts. Manifest description was aligned with the central default and build was rerun successfully. **Files Changed**: * `public-website/public/site.webmanifest` - Aligned manifest description with central metadata default. * `.spec_system/specs/phase13-session03-seo-metadata-and-static-site-plumbing/implementation-notes.md` - Recorded build and artifact inspection evidence. **BQC Fixes**: * Contract alignment: Manifest, homepage metadata, RSS, robots, and sitemap output now agree on site identity and canonical origin. *** ### Task T019 - Run focused Biome format and lint checks **Started**: 2026-06-01 17:31 **Completed**: 2026-06-01 17:32 **Duration**: 1 minute **Notes**: * Ran focused Biome format checks for touched website metadata files and session artifacts. * Initial format check reported line-wrapping differences in `JsonLd.astro` and `metadata.ts`; applied `biome format --write` to the focused file set. * Reran focused Biome format and lint checks successfully with no remaining fixes. **Files Changed**: * `public-website/src/components/seo/JsonLd.astro` - Formatted long JSON-LD validation and serialization lines. * `public-website/src/lib/metadata.ts` - Formatted long helper function signatures. * `.spec_system/specs/phase13-session03-seo-metadata-and-static-site-plumbing/implementation-notes.md` - Recorded Biome evidence. **BQC Fixes**: * N/A - formatting and lint verification only. *** ### Task T020 - Validate ASCII/LF encoding and record verification notes **Started**: 2026-06-01 17:32 **Completed**: 2026-06-01 17:32 **Duration**: 1 minute **Notes**: * Ran an ASCII and CRLF scan over touched website and session files. * Confirmed `ASCII_OK` and `LF_OK`. * Recorded final SEO/static plumbing verification evidence below. **Files Changed**: * `.spec_system/specs/phase13-session03-seo-metadata-and-static-site-plumbing/implementation-notes.md` - Recorded final encoding and verification notes. **BQC Fixes**: * Contract alignment: Final verification confirms the generated metadata artifacts match the intended canonical origin and static-site contract. *** ## Verification Summary | Check | Result | | -------------------------------------- | ---------------------------------------------- | | Package typecheck | Passed with Node 26.2.0/npm 11.16.0 | | Package build | Passed with Node 26.2.0/npm 11.16.0 | | Focused Biome format | Passed after formatting two new metadata files | | Focused Biome lint | Passed | | Generated homepage metadata inspection | Passed | | Generated RSS inspection | Passed | | Generated robots inspection | Passed | | Generated manifest inspection | Passed | | Generated sitemap inspection | Passed | | ASCII/LF scan | Passed | Final rerun after formatting and final notes updates passed at 2026-06-01 17:35: * `npm --prefix public-website run typecheck` * `npm --prefix public-website run build` * Focused `biome format` * Focused `biome lint` * ASCII/LF scan Generated `dist/index.html` includes canonical, description, robots, Open Graph, Twitter, RSS discovery, manifest, favicon, and JSON-LD tags rooted at `https://faction-os.com/`. `dist/rss.xml` builds as a valid empty feed. `dist/robots.txt` allows crawl and references the sitemap index. ## Session Summary * Completed all 20 tasks for Session 03. * Added central site metadata, URL, contact, destination, and structured-data configuration. * Added reusable SEO and JSON-LD components plus canonical and robots helpers. * Wired `BaseLayout`, `ContentLayout`, `LegalLayout`, and the homepage to the shared metadata contract. * Added static `robots.txt`, `site.webmanifest`, RSS route, and favicon accessibility metadata. * Preserved the static Astro output model and did not add analytics, server adapters, auth, hosted forms, CMS, React, Tailwind, or unreviewed media. --- # Agent Instructions This documentation is published with GitBook.
