Subject: [PATCH 1/5] docs(css): archive 36 superseded Oct-2025 consolidation
 docs (falsified plan)

All encode the dead 70-80%-duplication-elimination goal: foundation-extraction
ROI math, 'NEVER touch FL layouts' preservation rules, swarm execution prompts,
stale baselines. Falsified by compiled+gzip evidence (Phase 1 WP1.2/1.4 +
Phase 2 sprint-7 audits). Moved whole into 70-79-archives/superseded-2026-07-12/
with a README stating why. No content edits.

+# Superseded 2026-07-12
+
+Everything in this folder encodes the original Oct-2025 plan — "eliminate 70-80%
+CSS duplication (27,094–31,536 lines)" via shared-foundation extraction and
+consolidation — which was falsified on compiled+gzip evidence during Phase 1
+(WP1.2/WP1.4) and the Phase 2 audits (sprint 7, 2026-07-12): PurgeCSS runs per
+bundle, so each page already ships only its own FL subset, and any shared
+foundation is net-negative on first-visit transfer size. The `.fl-visible`
+duplication claim measured 41.9%, not 90-95%; the "7 FL layout files" count was
+actually 17 (16 after the e93d9b85 bundle merge).
+
+Kept for history only. The current authority is
+`../../2026-07-12-css-maintainability-redesign.md` (strangler rewrite plan) and
+`../../TASK-TRACKER.md`.

19 external bundles mapped to owning templates, FL files, and measured gzip
sizes (converged production build 2026-07-12); reverse map of all 16 live FL
layout files with consuming bundles and retirement status. Includes the
easy-to-miss repo-root layouts/course/list.html → course-list bundle.

+# CSS bundle ownership map + FL burn-down
+
+Answers "which pages does this CSS file affect?" for every bundle and file.
+Sizes measured 2026-07-12 from a converged production build (`gzip -c | wc -c`).
+Update this map whenever a resource slice changes; flip statuses as rewrite
+sprints land (see `2026-07-12-css-maintainability-redesign.md`).
+
+## External bundles (19)
+
+Each page type loads ONE fingerprinted bundle, built by concatenating its
+template's resource slice through PostCSS (per-bundle PurgeCSS — a page ships
+only its own subset; see the evidence rule in the redesign spec).
+
+| Bundle | Owning template | FL layout files in slice | gzip | Status |
+|---|---|---|---|---|
+| homepage | `home.html` (partial `homepage-css-resources.html`) | 590-layout | 29.6K | live-FL |

+| pagination | `list.html` (second bundle) | — (pagination.css only) | 0.2K | no-FL |
+
+Inline bundles (in `<head>` via `css-inline.html`, baseof.html): `navigation`
+(css-variables + navigation.css, site-wide) and `components` (components.css,
+site-wide). Not FL-affected.
+
+Shared non-FL slice members loaded by most bundles: `critical/base.css` (pulls
+the critical/fl-* trio), `dynamic-icons.css`, `586.css`, `vendors/base-4.min.css`,
+`style.css`, `skin-65eda28877e04.css`, `footer.css`, plus per-page extras

+`companies.css`, `careers.css`, `404.css`, `pagination.css`,
+`component-bundle.css`, `theme-main.css`).
+
+## FL layout file burn-down: 16 → 0
+
+Generated FL-Builder export CSS under `themes/beaver/assets/css/`. A file is
+RETIRED when its last consuming bundle's page is rewritten (semantic HTML +
+`css/pages/*.css`) and the file is deleted.

line-count target); CUMULATIVE METRICS → burn-down + historical note; Phase 3
WP definitions closed as superseded (preserved in git history + archives);
QUICK ACTIONS + navigation repointed to the spec and ownership map; sprint-8
update-log entry added. Spec count fix: 17→16 live FL files (PR #363 merged
e93d9b85 away — reviewer finding).

 ## 🎯 GOAL OVERVIEW
 
-**Objective**: Eliminate 70-80% CSS duplication (27,094-31,536 lines)
-**Approach**: 3-phase execution with micro-commit discipline
-**Execution Mode**: Solo autonomous (NO swarm spawning for mechanical work)
-**Success Criteria**: 100% test pass rate, zero visual regressions maintained
+**Objective**: Every style hand-editable, understood, single-source — FL export CSS 16 files → 0
+**Approach**: Phase 0 scaffolding, then one-page-per-sprint full rewrites (semantic HTML + token-based page CSS), easiest first
+**Execution Mode**: One feature branch + one bundled PR per sprint; read-only audit agents allowed, mutations sequential
+**Success Criteria**: FL burn-down to zero; no hash-named/obfuscated files; no duplication in the hand-maintained layer; both snapdiff suites green with every non-target page 0.0-diff

-### Work Package Status
+**Phase Status**: ❌ Superseded before start — closed 2026-07-12 (never begun)
+**Reason**: Its premise (source-level pattern consolidation into shared foundation
+files, measured in raw line counts) is the same methodology falsified by Phase 1
+(WP1.2/WP1.4) and the whole of Phase 2: PurgeCSS runs per bundle, so each page
+already ships only its own FL subset — foundation extraction grows shipped bytes.
+WP3.1/WP3.2 also proposed `.scss` files in a Sass-less pipeline. WP3.3's Hugo
+enhancements (hugo_stats.json, PurgeCSS, safelists) already exist in production.
+The WP3.1-3.4 definitions are preserved in git history (commit 2388c437 and
+earlier) and the archived plan docs under `70-79-archives/superseded-2026-07-12/`.

Subject: [PATCH 4/5] docs(css): rewrite PROJECT-INDEX to current plan; banner
 loading-order doc; repoint CLAUDE.md CSS row
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

PROJECT-INDEX was wall-to-wall dead plan (35.04 as PRIMARY AUTHORITY, 44,420→
11,884 line targets, WP tables) — replaced with a slim hub: spec, tracker,
ownership map, banner'd loading-order reference, standing constraints.
css-loading-order-analysis keeps its accurate load-order mechanics but gets a
supersede banner on its extraction-strategy framing. CLAUDE.md 'ANY CSS
changes' pointer now sends readers to the spec + ownership map instead of the
inverted FL-preservation rules.

-## 🚨 CRITICAL CONSTRAINTS
-
-### Zero-Tolerance Policies
-- ✅ **100% test pass rate** - ALL tests must pass after every change
-- ✅ **Zero visual regressions** - ≤3% screenshot tolerance (0% for refactoring)
-- ✅ **Micro-commits** - ≤3 lines per commit, commit on green tests
-- ✅ **Solo autonomous execution** - NO swarm spawning for mechanical work
-- ✅ **Test-after-each-change** - Run `bin/rake test:critical` after every file change
-
-### Out of Scope (Deferred)
-- ❌ FL-node HTML migration (572 HTML refs + 8,449 CSS rules)
-- ❌ BEM class system replacement
-- ❌ Complete CSS architecture redesign
-- ❌ Visual design changes
-
-### Hugo Pipeline Status
-- ✅ **Already Optimal**: resources.Concat, PostCSS, fingerprinting, minification
-- 🎯 **Our Goal**: SOURCE CSS duplication elimination (NOT pipeline changes)
-- 📋 **Phase 3 Optional**: PurgeCSS, automated critical CSS (can be separate initiative)
-
----
-
-## 🛠️ VALIDATION COMMANDS
-
-### After Each Change
-```bash
-# Run critical test suite (MANDATORY)
-bin/rake test:critical
-
-# If GREEN → commit and continue
-# If RED → rollback immediately, investigate, fix
-```
-
-### After Each Work Package
-```bash
-# Full validation protocol
-bin/rake test:critical                    # All tests
-bin/rake test:visual                      # Visual regression
-lighthouse http://localhost:1313          # Performance metrics
-```
-
-### CSS Analysis
-```bash
-# Check duplication levels
-grep -r "FL-row" themes/beaver/assets/css/fl-*.css | wc -l
-
-# Validate PostCSS compilation
-hugo --gc --minify
-```

+1. **[2026-07-12-css-maintainability-redesign.md](2026-07-12-css-maintainability-redesign.md)** — PRIMARY AUTHORITY.
+   The approved plan: goal, success criteria, Phase 0, the per-page rewrite
+   protocol, rewrite order, and the evidence rule (validate on compiled+gzip
+   per-page payload, never raw source line counts).
+2. **[TASK-TRACKER.md](TASK-TRACKER.md)** — live status: Phase 0 items, FL
+   burn-down, sprint update log (the full history of how the old plan was
+   falsified lives here).
+3. **[css-bundle-ownership-map.md](css-bundle-ownership-map.md)** — "which pages
+   does this CSS file affect?": 19 bundles × owning template × FL files × gzip,
+   plus the 16-file FL burn-down table. Update it whenever a resource slice changes.
+4. **[css-loading-order-analysis.md](css-loading-order-analysis.md)** — how each
+   template assembles its bundle and why load order matters. Read the supersede
+   banner first: its FL-preservation rules predate the strangler plan.
+
+## 🧭 The plan in one paragraph
+
+The original Oct-2025 goal ("eliminate 70-80% CSS duplication, 27,094-31,536
+lines" via shared-foundation extraction) was falsified on compiled+gzip
+evidence: PurgeCSS runs per bundle, so every page already ships only its own
+FL subset, and extraction grows shipped bytes. The replacement plan strangles
+the generated FL-Builder CSS instead: Phase 0 adds missing snapdiff coverage
+(special-content blog posts: Mermaid, code highlighting, inline styles,
+youtube embeds) and an orphan-file guard; then one page per sprint gets a full
+rewrite — semantic HTML + one small token-based file under `css/pages/` — with
+its FL file deleted in the same PR, every other page proven 0.0-diff on both
+suites (`bin/test` + `bin/dtest`), and design improvements per JetVelocity
+(`.stitch/design.md`) approved via screenshots.

+## 🚨 Standing constraints
+
+- Gates on every commit: `bin/test` (macOS) AND `bin/dtest` (Linux); baselines
+  change only intentionally (`FORCE_SCREENSHOT_UPDATE=true`, both platforms in
+  the same commit). No new custom baseline/compare scripts — missing coverage
+  is fixed by adding tests.
+- One feature branch + ONE bundled PR per sprint; rollback = revert one PR.
+- Evidence rule: any size/perf claim is measured on compiled+gzip per-page
+  payload. Known build noise: `sw.js?v=` cachebuster, taxonomy term-casing races.
+- Production-only pipeline traps (dedup/purge) are documented in the update log
+  and in `~/.claude` project memory — dev-server checks cannot catch them.

 # Hugo CSS Loading Order Architecture Analysis
 
+> **⚠️ PARTIALLY SUPERSEDED 2026-07-12.** This doc's load-order mechanics
+> (baseof inline bundles → per-page bundle, concat order inside a bundle) are
+> still accurate and useful. Its STRATEGY framing is not: "extraction sequence",
+> layer preservation rules, and any "NEVER extract/consolidate FL layouts as a
+> transfer-size win" reasoning belong to the falsified Oct-2025 plan. The
+> current plan RETIRES FL CSS page-by-page instead — see
+> `2026-07-12-css-maintainability-redesign.md` (authority) and
+> `css-bundle-ownership-map.md` (current bundle↔template↔file map with sizes).
+> Bundle names/hashes below are 2025-10-14 snapshots; trust the ownership map.
