EqualifyEverything / equalify-docs

Audit of this branch against equalify-reflow main surfaced several drifts where the code has moved and the consumer docs haven't. This commit handles the unambiguous ones — the corrections with a single right answer. The audience-depth issues in architecture.md (Service Layer section is too contributor-deep for consumers) and one uncertain PII-findings claim in integrate-via-api.md are left for follow-up. - explanation/how-it-works.md: drop the 'not yet publicly available, we plan to open-source…' paragraph. Repo is live at EqualifyEverything/equalify-reflow (AGPL-3.0-or-later). This paragraph contradicted README.md and getting-started.md in the same doc set. - how-to/provide-feedback.md: fix broken link `wordpress-plugin.md` → `use-the-wordpress-plugin.md` (same how-to/ directory; file was renamed during the reorg). - explanation/architecture.md: - Fix broken `wordpress-plugin.md` link → `../how-to/use-the-wordpress-plugin.md` - LocalStack → Floci (migration landed in reflow PR #110) - Rewrite the Model section to cover the two-tier + dual-backend reality: Haiku 4.5 default / Sonnet 4.5 for heavier work, Bedrock in prod with Anthropic direct as a pluggable alternative. SSE user_phase coverage (also flagged by the audit) was already applied in dcff2f3 + c118342. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
