test(frontend): add jsdom + React Testing Library harness - #78

…s structure, correct a false CVE claim in the CHANGELOG (#102)

* docs(archive): make §14 contiguous, add a newest-first index, and add the finding-ID decoder

Twelve dated §14 entries — every one from 2026-07-09 onward, including all the
recent work — sat underneath `## Build performance` rather than under §14, so
anyone scrolling §14 to the end stopped short of them. Moved the Build
performance section to the end of the file instead of re-parenting the entries:
it is self-contained and cross-referenced by heading name (from CLAUDE.md and
four workflows), not by position, so nothing breaks. All 104 dated entries are
now under §14.

Added a newest-first index at the top of §14, one anchored line per entry. The
entries themselves are deliberately NOT reordered: sixteen of them refer to each
other relatively ("the entry below", "superseded by the entry above"), and a
sort would silently invert every one. The three ordering regimes are documented
instead, and the index is sorted by date regardless of physical position, so
lookup no longer depends on the scroll order.

Added §15, a finding-ID index: one row per SEC/SC/APIR/CON/P1-P3/D/R/QUA/INF/
FE/API/FEAT/DOC/SCN id with a one-line description and its resolving PR. §14
cites these ids bare and never re-explains them; this is the decoder that
replaces the docs/reviews/ reports. It also records the SEC-* prefix collision
between the two reviews that reused it.

Corrected §0 locked decision #7: it said CVE-2025-15366 and CVE-2025-15367 are
both unfixable on 3.14. That is true of released 3.14.6 but not of the 3.14
line — the imaplib backport landed on the maintenance branch and closes on
3.14.7 (issue #98). Only the poplib CVE remains 3.15-only (#52).

* docs(changelog): correct the CVE-2025-15366 claim under [Unreleased]

The Python 3.14 entry said all four waived CPython CVEs remain unfixable until
3.15 because upstream declined the backport to 3.10-3.14, and pointed at issue
#52 for all of them. Both halves are false, and this text ships verbatim as the
next release's notes.

Checked against ci/grype.yaml and the two 2026-07-26 §14 entries: the imaplib
backport for CVE-2025-15366 merged onto the CPython 3.14 branch on 2026-07-07 —
18 days before the entry was written — so it closes on 3.14.7, not 3.15, and it
was regrouped into Group A alongside CVE-2026-15308 and CVE-2026-12003, tracked
in issue #98. Only CVE-2025-15367 (poplib) is genuinely 3.15-only and still
tracked in #52.

What was true and is kept: released 3.14.6 carries neither guard, so the upgrade
cleared nothing at the pinned version.

* docs: strike completed roadmap items, surface the settings-level work, add two process rules

ROADMAP:
- Struck "Pin GitHub Actions to commit SHAs" (done in #57 — ci.yml has 8
  SHA-pinned uses:, dev-nightly 3, publish 3, rescan 2) and "Frontend test
  runner" (done in #78 — vitest 3.2.7, "test": "vitest run", 20 test files).
- Rewrote "Row-bound secret AAD", which was false as stated: row binding is
  implemented (secret_store.py row_aad(), L1/SEC-7, #64) and every write is
  row-bound. What remains is only the bulk re-encryption of legacy column-only
  ciphertext so the read fallback can be dropped, so it is folded into the
  existing "Admin bulk secret re-encryption" item.
- Extended the public-repo governance checklist with five settings-level items
  that existed only in §14 prose and were therefore invisible: Actions workflow
  permissions -> read-only, confirm GHCR package visibility is public (the
  original check asked for Private and its premise inverted when the repo went
  public), delete the unused DOCKERHUB_* secrets, set the GitHub profile display
  name to tyler-rich, and confirm Dependabot security alerts are on.

CLAUDE.md § Git & PR conventions gains two rules learned the hard way: a stacked
child PR retargeted after its parent was squash-merged needs git rebase --onto
(flipping the base in the UI re-computes the merge base and balloons the diff),
and on: pull_request does not fire on 'edited', so a base change never re-runs
CI and the green check you are looking at is from the old base.

CONTRIBUTING § Releasing gains a "Before you tag" checklist — CHANGELOG
[Unreleased] reviewed (it ships verbatim), THIRD_PARTY_LICENSES verified against
the versions actually pulled, Dependabot PRs triaged, requirements.lock
regenerated — plus the two after-tag steps: back-merge main into dev, and re-run
rescan.yml.

* docs: delete docs/reviews and docs/upgrades, sweep every inbound reference

The twelve review reports and the Python 3.14 handoff doc held only closed
findings, and sat at the same directory level as the two live documents. They
are removed rather than moved to a docs/history/ subtree: the only real argument
against deleting them was that §14 cites their finding ids bare and never
re-explains them, and §15 (previous commit) answers that directly. Git is the
archive for the rest. docs/ now contains exactly ARCHIVE.md, ROADMAP.md, and
screenshots/.

The originals stay retrievable — the pre-deletion commit is
0780b07, and the §14 entry records the
git show incantation. Nothing was rewritten before deletion.

Swept every inbound reference the audit enumerated, plus the ones it did not:
CONTRIBUTING § Project layout (both directories dropped, screenshots/ added),
CONTRIBUTING § API conventions, CHANGELOG's L13/APIR-8 citation, and both
dependabot.yml D3 comments now point at ARCHIVE §15. Inside §14, 59
docs/reviews/ and 7 docs/upgrades/ path prefixes were stripped so the entries
name the reports as documents rather than as paths that no longer resolve, with
a note at the top of §14 sending the reader to §15. Fixed the dead
claude-md-compliance-review.md link (a filename that never existed). Left one
docs/upgrades/ mention deliberately: the 2026-07-25 entry's record of what
CONTRIBUTING's layout listing omitted is a statement about that date, marked
'(as it then was)'.

Verified no workflow, test, or source file referenced either directory, and that
the four '§ Build performance' cross-references are by heading name and survive
that section's move.

Added the dated §14 entry recording all of it, including that docs/history/ was
considered and rejected, and two corrections to the audit: twelve entries were
misfiled under Build performance (not fourteen — the other two are that
section's own sub-headings), and there are 42 remote branches with 36 prunable
(not 39/33).
