Adds deploy/crushdb.service: plain HTTP on 127.0.0.1:5000 (HOST/PORT
env), auto-restart on failure, hardened with ProtectSystem/strict,
NoNewPrivileges, capability drop and restricted address families so
only the SQLite dir and private tmp are writable. Passes
systemd-analyze verify (the one reported warning is the expected
/path-in-this-repo venv path of the source checkout, not the deployed
one).

TLS termination belongs to the trusted reverse proxy in front
(nginx/caddy/...), not the app. run.py now binds plain HTTP to
127.0.0.1 (HOST/PORT configurable) and the dirty rollback of the
reverted self-signed-cert logic was cleaned up. README updated.
Verified: all endpoints 200 over HTTP, integrity tests 3/3 passing.

run.py now ensures a self-signed TLS certificate exists (openssl,
SAN localhost/127.0.0.1, 365 days) and serves on https://127.0.0.1:8443.
Falls back to plain HTTP with a loud warning only when openssl is
unavailable. Verified end-to-end with curl over TLS.

Adds pytest suite proving server-side tamper/replay guarantees:
stale-version updates and deletes are refused (409), duplicate uuids
are rejected, and post-delete resurrection scenarios are documented.
Combined with the client-side AEAD binding of uuid+salt any server-side
manipulation surfaces as an undecryptable row in the UI. 3/3 passing.

Vanilla HTML/CSS/JS frontend served by Flask:
- Unlock screen: passphrase -> Argon2id session key, held in memory
only (never sent to the server); "Sperren" wipes key and DOM rows.
- Records table (Person A/B, start/end, action) rendered via
textContent only (no HTML injection); undecryptable rows are flagged.
- Create/edit modal encrypts payloads with XChaCha20-Poly1305 before
any network call; updates carry the server version (optimistic lock,
conflict toast on 409); delete fetches current version first.

Adds a vanilla ES-module crypto layer for the browser:
- Argon2id (t=2, m=16 MiB, p=1) derives a 256-bit session key from the
passphrase; the passphrase never leaves the client.
- Records are encrypted with XChaCha20-Poly1305, fresh 24-byte nonce
per record, per-record salt bound into the AEAD associated data
together with the uuid (tamper/swap detection).
- Vendored audited @noble/hashes + @noble/ciphers ES modules; verified
end-to-end in node (encrypt/decrypt roundtrip, wrong key, tampered
salt, swapped uuid all rejected).

Exposes a ciphertext-only REST API: list/get/create/update/delete of
records as opaque base64 blobs. Enforces base64/size validation,
rejects duplicates, and uses patch-version checks server-side so
replayed or stale updates are refused. Includes run.py entry point
that enables TLS when certs/ are present. Verified via test client.

Adds the base project setup (requirements, README, gitignore entries)
and a SQLite storage layer that persists only encrypted records:
uuid, ciphertext, nonce, salt, plus a monotonic version counter used
later for tamper/replay detection. Includes a smoke test run.
