docs: archive the finished backlogs (RD-30)

Two backlog trees are complete: `docs/project/backlog/` (75 files, every
WP done) and `docs/project/refactor-backlog-setup/` (the arc before it).
Move both under `docs/project/archive/` with `git mv`, so history stays
intact through `git log --follow`. `SHOWCASE-ROADMAP.md` moves with them,
because it points at the now-archived backlog README.

Add `docs/project/archive/README.md`. It states that these trees are
historical and names the two directories that are still live.

Repoint every inbound reference named in RD-30's Files table: CLAUDE.md,
the root README, both backend READMEs, `LetterHtml.cs`, `a11y.mdx`, the
`document-feature` and `new-ssp` skills, and the readable-codebase PLAN,
README, and RD-19 ticket. Fix two upward-relative links inside the moved
WP files (WP-68, WP-69) that gained a directory level and would otherwise
break. Repoint `.prettierignore`'s two agent-prompt exclusions to their
new path, so prettier keeps leaving those files' exact wording alone.

Mark RD-30 done and check off its acceptance criteria; flip its README
row to done.

# ADR-C-001 — rewrite ADR-0001's worked example against the shipped system
Status: **implemented** · 2026-08-27 · Source finding: `06-adr-conformance.md` §ADR-C-001
## What was wrong
ADR-0001's §"Worked example in this POC" opened with _"This POC has no real backend (static
mock JSON + fake submit timers), so the 'BFF output' is a static file"_. That premise is
false and every path the section cited was gone. The decision itself was intact; only the
description had drifted.
## What changed
| File | Change |
| -------------------------------------------------------- | --------------------------------------------------------------------------- |
| `docs/reference/architecture/0001-...md` §Worked example | rewritten against `backend/src/BigRegister.Api`; all six paths repointed |
| same file, §Out of scope here | 4 bullets → 2, plus a paragraph recording which two were discharged and why |
No code changed. No CLAUDE.md edit was required for this finding.
## Paths corrected, each verified
| Claimed | Actual |
| -------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------ |
| "no real backend … static file" | `backend/src/BigRegister.Api`, `var api = app.MapGroup("/api/v1")` at `Program.cs:168` |
| `public/mock/dashboard-view.json` | `GET /api/v1/dashboard-view` (`Program.cs:172`) |
| `public/mock/intake-policy.json` | `GET /api/v1/intake/policy` (`Program.cs:193`) |
| `src/app/registratie/contracts/dashboard-view.dto.ts` | `apps/ssp/src/app/registratie/contracts/dashboard-view.dto.ts` |
| `src/app/registratie/infrastructure/dashboard-view.adapter.ts` | `apps/ssp/.../infrastructure/dashboard-view.adapter.ts`, `parseDashboardView` at `:50` |
| `src/app/herregistratie/contracts/intake-policy.dto.ts` | **deleted** — the DTO is now the generated `IntakePolicyDto`; the adapter is `apps/ssp/src/app/herregistratie/infrastructure/intake-policy.adapter.ts` |
`apps/ssp/public/mock/` does not exist (`ls`: no such directory).
## The finding was wrong about one out-of-scope bullet
ADR-C-001 said to _"reduce §Out of scope to the two items still genuinely open (the
`BigProfileStore` optimistic-update race, and session persistence / multi-tab sync)"_,
carrying the original bullet's parenthetical **"`SessionStore` is in-memory"**. That
parenthetical is no longer true, so the bullet could not be kept verbatim.
- `apps/ssp/src/app/auth/application/session.store.ts:13` reads
`parseStoredPrincipal(localStorage.getItem(STORAGE_KEY))`, and `:41` writes it back.
Session persistence **has landed** (RB-10 extracted the parser, RB-13 renamed it
`parseStoredPrincipal`). The file even carries a `ponytail:` note explaining the choice of
`localStorage` over `sessionStorage`.
- Multi-tab sync has **not** landed: `grep` for a `storage` event listener across `apps` and
`libs` returns nothing.
The bullet was therefore narrowed to multi-tab sync only, and states that the session itself
now persists. Recording this because the finding, taken literally, would have re-asserted a
false claim in the same edit that removed two others.
The other two survivors were verified rather than assumed: `BigProfileStore` still holds
`pending` as a bare `signal(false)` with `begin`/`confirm`/`rollback` mutating it
(`big-profile.store.ts:61-74`), so the concurrent-submit race is real.
## Discharged bullets, both verified
- _"Runtime DTO validation on **every** endpoint (only the dashboard view has it)"_ — 33
distinct `export function parse*` boundary functions exist across `apps` and `libs`.
- _"Real OpenAPI/TypeSpec codegen toolchain"_ — `npm run gen:api` (`package.json:12`) runs
`dotnet swagger tofile` then `nswag run`, emitting
`libs/shared/src/infrastructure/api-client.ts` (2329 lines). CI's `api-client-drift` job
regenerates and runs `git diff --exit-code` (`.github/workflows/ci.yml:319-321`).
## Scope discipline
Descriptive drift only, as the finding states. The decision, the options table, the two
policy shapes and the migration sequence are untouched.
