Adversary cold-verify of F2-9 FAILED: the read-back's CKEditor-frame-attach wait timed out on a fresh cold context (flaky, not 3x-reliable). Fix: read-back now polls EVERY frame's body text for the marker (don't require the specific ckeditor-inner frame to attach — that's the flaky part) with a generous ~240s deadline + periodic reloads to unstick cold loads. The marker appearing in a fresh context still proves server-side E2E-encrypted persistence (only URL+fragment key carried over). Also bumped the session-1 post-type sync wait 9s→12s. F2-13 Adversary-owned; will validate cold before it closes F2-9. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

"""cryptpad — §4.3 create-an-object + read-it-back (Phase 2 P3 + P6); resolves F2-9.
|
|
|
|
CryptPad is end-to-end client-side encrypted: the server only ever stores ciphertext, and the
|
|
decryption key lives in the URL fragment (`#/2/pad/edit/<key>/`). So "create a pad, confirm it
|
|
persists" cannot be done with bare curl (plan §4.3 note) — it must be a real browser flow. This test
|
|
proves genuine persistence of decrypted content across a FRESH browser session:
|
|
|
|
1. Open `/pad/` in a browser; CryptPad auto-creates a new anonymous pad and writes the edit URL
|
|
(fragment-keyed) into the address bar. Capture that full URL.
|
|
2. Type a unique marker into the CKEditor rich-text body (nested sandbox iframe).
|
|
3. Wait for CryptPad to sync the encrypted update to the server ("Saved").
|
|
4. Open a **brand-new browser context** (no shared localStorage/cookies — a different "session")
|
|
and navigate to the captured pad URL.
|
|
5. Assert the unique marker is present in the re-decrypted pad body.
|
|
|
|
Step 4's fresh context is the real proof: the only thing carried over is the URL (incl. its
|
|
fragment key), so a successful read-back means the content was persisted server-side (encrypted) and
|
|
correctly decrypted by a new client — not merely cached locally. This is the §4.3 create-and-read-back
|
|
floor for CryptPad, not a health/SPA-render stand-in.
|
|
|
|
Empirically mapped against the recipe under test (CryptPad 2026.2.0): the editor lives in a deeply
|
|
nested frame `…/pad/ckeditor-inner.html` (top page → `#sbox-iframe` on the sandbox domain → CKEditor
|
|
frame); first init compiles LESS (~15s on a cold cache), so the frame hunt and hash wait are patient.
|
|
Transient `net::ERR_NETWORK_CHANGED` is handled by the shared `goto_with_retry` (F2-3).
