 ### B265 — Address keys whose token is for an inactive account key never open
 
-**Status:** Open
+**Status:** Fixed, not verified live
 **Found:** 2026-10-31, code audit after issue #40: a Duo account whose mount failed on every
 start with `fetch My Files root: cryptography error: failed to decrypt: missing key`, after three
 `failed to decrypt address key token` warnings. The web app worked. B210's fix does not apply,
@@ -560,8 +560,17 @@ already reports "token is for inactive account key", so the case is known. Separ
 `addresses()` fails as a whole through `?` when one address has no usable primary key, which
 takes the working addresses down with it.
 
-**Fix.** Not done, and it belongs in the SDK. Use every account key that opens for decrypting
-tokens, and only the active ones for signing. Skip and log an address that cannot be opened.
+**Fix.** In `proton-sdk` 0.10.1 (narrrl/proton-sdk-rs#3). Tokens are tried with every account
+key that opens, active ones first, and signing uses active keys only. An address that cannot be
+opened is left out with a warning, and the others work; `addresses()` fails only when none
+opens. When the left-out address is the default, `default_address` fails with the reason
+rather than signing with another address. `key_report` walks the same chain, so `pdfs diagnose`
+reports such a key as opening. Not verified against an account with an inactive key, since
+none is at hand; issue #40's reporter can confirm.
+
+**Test:** `an_address_key_whose_token_is_for_an_inactive_account_key_opens`,
+`an_address_whose_keys_do_not_open_leaves_the_others_working` and
+`an_account_whose_addresses_all_fail_to_open_is_an_error` in `proton-sdk`.
