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.

# RB-32 — add the missing `language-switcher` row to the CIBG gap register
Status: **implemented** · 2026-08-28 · Source finding: `06-adr-conformance.md`
ADR-C-008 · `99-backlog.md` RB-32 · Depends on
`implementation/adr-c-007.md` (the same file, left one row short on purpose,
filed forward as this ticket)
## What was wrong
ADR-0003 §Consequences' final bullet requires every `// CIBG-GAP EXTENSION:`
marker in code to have a row in `libs/shared/docs/cibg-gaps.mdx`, "so it's
auditable rather than silently drifting." `libs/shared/src/layout/language-switcher/
language-switcher.component.ts:7-9` carries a full, well-formed marker
("Taal instellen" — no vendored Huisstijl class ships for it — see
`cibg-gaps.mdx`) but the register table had no row for it.
## Verified before editing
```
grep -rln "CIBG-GAP EXTENSION" apps libs --include=*.ts | wc -l # 9
```
Nine files carry the marker: `debug-state`, `language-switcher`, `wizard-shell`,
`application-link`, `placeholder-chip`, `rich-text-editor`, `skeleton`,
`spinner`, `status-badge`. The register table had 8 rows, and `language-switcher`
was the one missing — matching ADR-C-008's finding exactly, re-verified rather
than trusted from the finding's own snapshot (per this ticket's DoD point 1, and
per `adr-c-007.md`'s own note that it left this exact row for a later ticket).
## What changed
One row added to `libs/shared/docs/cibg-gaps.mdx`'s register table, matching the
existing rows' two-column shape (component name, closest CIBG concept, reason —
wording taken from the component's own marker comment, not invented):
| Component | Closest CIBG concept | Why hand-rolled |
| ------------------- | -------------------- | -------------------------------------------------------------------------------------------------- |
| `language-switcher` | Taal instellen | No vendored Huisstijl class ships for it; a small hand-rolled surface built from the token bridge. |
No other row was touched. The 8 existing rows were each re-checked against their
component's current marker comment while the file was open; none needed a change.
## Optional CI script: taken
ADR-C-008 flags a ~10-line `grep -l CIBG-GAP | diff`-style script folded into
`check:tokens` as an explicitly optional second step. It is genuinely small and
fits the existing script's shape, so `scripts/check-tokens.sh` gained one more
guard after its existing hardcoded-colour check:
```bash
gap_register='libs/shared/docs/cibg-gaps.mdx'
markers=$(grep -rl 'CIBG-GAP EXTENSION' apps libs --include='*.component.ts' | xargs -n1 dirname | xargs -n1 basename | sort -u)
rows=$(grep -oP '^\| `\K[^`]+' "$gap_register" | sort -u)
missing=$(comm -23 <(echo "$markers") <(echo "$rows"))
if [ -n "$missing" ]; then
echo "$missing"
echo "FAIL: CIBG-GAP EXTENSION marker(s) with no row in $gap_register"
exit 1
fi
echo 'OK: every CIBG-GAP EXTENSION marker has a cibg-gaps.mdx row'
```
The marker's component directory basename (`dirname` of the flagged file,
`.component.ts` files only) is compared against the table's backtick-quoted
first column, extracted with `grep -oP`. This matches for all 9 current
markers, including the two rows with a parenthetical suffix
(`` `wizard-shell` (error summary only) ``, `` `application-link` (non-navigating
row) ``) — the regex stops at the closing backtick, before the parenthetical.
**Verified working, not just written.** Added a scratch component
(`libs/shared/src/ui/scratch-gap-test/scratch-gap-test.component.ts`, a single
`// CIBG-GAP EXTENSION:` line plus a dummy export) with no matching row. Ran
`bash scripts/check-tokens.sh`: failed with exit 1, printing `scratch-gap-test`
and the expected `FAIL:` line. Deleted the scratch file and its directory (`rm`,
not `git checkout` — it was never tracked). Re-ran the script: passed, exit 0.
`git status` confirms no trace of the scratch file remains.
## Verification
- `npm run check:tokens` (includes the new guard): passes — 9 markers, 9 rows,
after the register row was added.
- `npm run ci`: result and step count reported in the implementing agent's final
answer.
- No code changed outside `libs/shared/docs/cibg-gaps.mdx`,
`scripts/check-tokens.sh`, `99-backlog.md`, and this note — a doc-only ticket
plus its optional, self-verifying guard script.
