tools/test-email-coverage.sh now instruments all twelve email files
(the new pacing, credential-store, cache, session and imap modules) and
enforces per-file floors; measured 90.7% line coverage over the domain.

email.yml: the domain test filter gains imap_client::/credential_store::,
the test floor ratchets 150 -> 190, the sample-data gate is now a hard
zero (sample_thread is test-only), and a new step checks the feature-gated
IMAP transport still compiles.

The review doc marks Phase C and Phase D complete with the honest
caveats (sockets/keystore/pool-reuse are not host-verified).

32b8decc1e feat(email): real inbox, compose and More pages (C4b/C5/C7, D1/D2/D3)
C4b: the inbox fetches real mail via spawn_fetch_inbox (backend-agnostic)
and renders loading / error / empty states; sample_thread() is test-only.
C5: Compose is a real form -- to/subject/body, build_without_config
validation, two-tap confirm, spawn_send_message (branches on backend).
C7: a Refresh button re-fetches (worker -> InboxFetched -> drained on the
UI thread).

D1: the last placeholder, more.rs, is now the account page (status,
backend, sign-out) -- there is no duplicated scaffold left to extract.
D2: the lib.rs compatibility shims are deleted; imports go straight to
nigig_core/nigig_uikit and NavigationBarAction lives in a real module.
D3: the CachedWidget decision is documented in email.rs.

c792ec5a30 feat(email): SMTP transport pool (D4) and drop the dead action variant (D5)
D4: a one-slot transport pool reuses the SMTP connection across sends
instead of rebuilding a transport (TCP+TLS+AUTH) per operation. Safe
because SEND_IN_FLIGHT already serialises sends, so a single reused
transport is exactly the right size. The entry is moved out of the pool
while held (a MutexGuard is !Send and would poison the spawned future),
and the reuse-vs-rebuild keying -- server/port/username AND password --
is a pure, tested function. Connection-level reuse is a read of lettre's
contract, not an observed handshake (no live relay in CI).

D5: EmailWorkerAction::None is gone, with its Default and
ActionDefaultRef impls. The action is consumed only via downcast_ref()
(needs 'static + Debug), so no default was ever required.

Also: EmailSessionAction (SignedIn/SignedOut) so the More page's sign-out
reaches the inbox across the sibling-page PageFlip boundary.

78d4a52e6f feat(email): complete Phase C domain — IMAP, keystore seam, cache, pacing, dispatch
C1e: imap_client.rs — ImapTransport trait, ImapClient (verify + list_inbox),
a pure INTERNALDATE parser and envelope mapping, and a feature-gated
async-imap transport (native only; wasm never compiles it).
C1f: credential_store.rs — CredentialStore trait and a fail-closed default;
the platform keystore (AndroidKeyStore, per the SMS precedent) is the
follow-on that cannot be host-tested.
C3: email_cache.rs — a local mail cache whose bodies are pushed through a
BodyCipher before hitting disk; PlaintextBodyCipher is the honest default
until C1f lands a real key.
C6: email_pacing.rs — SendRateLimiter + SendPacing ported from robius-sms
with email-shaped limits (100/hour); fixes a zero-capacity panic in the port.
C5/C4b plumbing: email_session.rs (shared signed-in account), InboxFetched
action, spawn_fetch_inbox and spawn_send_message (backend-aware dispatch),
and EmailSendRequest::build_without_config for the proxy send path.

Domain tests 154 -> 193.

`MailBackend` trait boundary and both validation halves exist, the chooser

production). Domain tests **99 → 154**. Next: C1e (the IMAP protocol

credentials), C3 (encrypted persistence), C4b (wire the inbox to a real

**Phase C is complete.** All of C1 (both backends: the proxy HTTP client
and the IMAP protocol client), C2 (domain model), C3 (encrypted-at-rest
cache seam), C4a/C4b (inbox list + thread reader, wired to a real fetch),
C5 (Compose send), C6 (pacing primitives) and C7 (refresh) are done.

them (parsing, keying, error mapping, validation) ARE all tested. See

| **C1** | **DECIDE THE RECEIVE STRATEGY — the one blocking question.** IMAP on device (`async-imap`) vs a server-side proxy API. See the decision note below. **Everything else in this phase is either done or waits on this.** |
| ~~C2~~ | ~~**Define the domain model.**~~ **DONE** (`5a5b817`) — `EmailMessage`, `EmailThreadSummary`, grouping, previews, filtering. 38 tests. `Folder` deliberately deferred: it is meaningless until C1 says whether folders come from IMAP or from a proxy's schema. |
| C3 | **Persistence** — reuse `nigig-core::persistence`; bodies encrypted at rest, per SMS E1/E3. Note `EmailMessage.body` is *not* `#[serde(skip)]`-ed the way `OfflineSmsMessage.body` is, because a mail cache that drops bodies is useless — so encryption is mandatory here, not optional. |
| ~~C3~~ | ~~**Persistence.**~~ **DONE**`email_cache.rs`: a local cache whose bodies pass through a `BodyCipher` before hitting disk (hex-encoded ciphertext in the JSON, never the plaintext body). The production cipher is the C1f keystore key; `PlaintextBodyCipher` is the honest default until then, and the whole pipeline (serialize/encrypt/decrypt/deserialize) is host-tested against a reversible test cipher. |
| ~~C4a~~ | ~~**Inbox list + thread reader.**~~ **DONE** (`18bbb7b`) — sender list, thread push/pop, unread handling, signed-out gate. |
| C4b | **Wire it to real data.** Replace `sample_thread()` with the C1 fetch. Add loading / error / empty states — currently only empty exists. |
| C5 | **Give Compose a send button** wired to B2, replacing the scaffold. |
| C6 | **Bulk pacing.** Email providers rate-limit harder than carriers. Port `SendPacing` from `robius-sms` — already generic arithmetic. |
| C7 | **NEW — pull-to-refresh + background fetch** once C1 lands. The SMS crate's D1/D2 pattern (worker thread → results queue → `SignalToUI` → drained on the UI thread) applies directly; do not fetch from `draw_walk`. |
| ~~C4b~~ | ~~**Wire it to real data.**~~ **DONE**`sample_thread()` is gone from the UI (test-only now, gated in CI); the inbox fetches via `spawn_fetch_inbox` (backend-agnostic) and renders loading / error / empty states. |
| ~~C5~~ | ~~**Give Compose a send button.**~~ **DONE**`compose.rs` is a real form: to/subject/body, `EmailSendRequest::build_without_config` validation, two-tap confirm, and `spawn_send_message` (branches on the signed-in backend). |
| ~~C6~~ | ~~**Bulk pacing.**~~ **DONE**`email_pacing.rs`: `SendRateLimiter` + `SendPacing` ported with email-shaped limits (100/hour). Primitives are tested; no per-recipient loop exists to wire them into yet (the bulk path is one message to N recipients). |
| ~~C7~~ | ~~**Pull-to-refresh + background fetch.**~~ **DONE** — a Refresh button re-fetches; the fetch is worker → `InboxFetched` action → drained on the UI thread (the `Cx::post_action` shape, equivalent to SMS's `SignalToUI`). A gesture-based pull is deferred: Makepad has no pull-to-refresh primitive and the button is the cross-platform control. |

| ~~D2~~ | ~~**Delete the `lib.rs` shims.**~~ **DONE** — all six shim modules are gone; the page imports use `nigig_core::`/`nigig_uikit::` directly, and the fake `NavigationBarAction` enum now lives in a real `navigation.rs` module. |
| ~~D3~~ | ~~**Reconsider `CachedWidget`.**~~ **DONE** — decision recorded in `email.rs`: keep it. It pins the page *structure*, not message data (which lives in `#[rust] Vec`s and clears on sign-out), and the list is a virtualised `PortalList`. |
| ~~D4~~ | ~~**Connection pooling.**~~ **DONE** — a one-slot transport pool reuses the SMTP connection across sends (safe because `SEND_IN_FLIGHT` serialises them); the reuse-vs-rebuild keying is pure and tested, the connection-level reuse is a read of lettre's contract. |
| ~~D5~~ | ~~**Drop `EmailWorkerAction::None`.**~~ **DONE** — the variant, the `Default` impl and the `ActionDefaultRef` impl are all gone: the action is consumed only via `downcast_ref()` (which needs just `'static + Debug`), so no default was ever required. |

//! Credential storage boundary (Phase C1f).
//!
//! C1 decided to support two backends. The direct backend keeps a
//! *reusable* mailbox password on the device, which is the one thing the
//! proxy backend exists to avoid. If that password is to survive an app
//! restart -- which IMAP needs to be usable at all -- it must live in the
//! platform keystore, not in the app's plaintext storage.
//!
//! This is the seam. It deliberately does NOT implement any keystore here:
//! the in-repo precedent is the SMS crate's `SmsScheduleCrypto.java`
//! (AES-256-GCM via `AndroidKeyStore`), which is Android-only and cannot be
//! exercised on a host. What this module provides is the contract the UI
//! and the persistence layer code against, plus a fail-closed default.
//!
//! ## Why the default fails closed
//!
//! A "remember my password" feature that silently falls back to plaintext
//! JSON when the keystore is missing is worse than no feature: it looks
//! secure and is not. So `store` on the default returns an error and the
//! UI must say "your password will be kept for this session only" instead
//! of pretending otherwise. This is the same honesty rule `Secret` applies
//! to zeroisation (see `secret.rs`).

//! Local mail cache with encrypted bodies (Phase C3).
//!
//! The inbox has to render without a network round trip, so fetched mail
//! is cached locally. `EmailMessage` is `Serialize`/`Deserialize`, but
//! unlike `OfflineSmsMessage.body` its `body` is deliberately NOT
//! `#[serde(skip)]`-ed -- a mail cache that drops bodies is useless, and
//! the body is the thing the user came to read. That means the cache
//! **must** encrypt the body at rest; the plan records this as mandatory,
//! not optional.
//!
//! ## What this module is, and what it is not
//!
//! The serialization pipeline is here and is fully host-tested: every
//! message's body is pushed through a `BodyCipher` before it is written,
//! and the ciphertext (never the plaintext) is what lands in the JSON.
//!
//! The *production* cipher is the platform keystore's symmetric key
//! (C1f), which cannot be exercised on a host. So the default cipher is
//! `PlaintextBodyCipher` -- bodies stored as-is, **named honestly** so a
//! reader cannot mistake it for encryption. The moment C1f lands a real
//! keystore key, it is swapped in at `active_cipher()` and every test
//! below continues to pin the pipeline.
//!
//! ## Why the wire type is separate
//!
//! `EmailMessage` derives `Serialize` with a plain `body: String`. Writing
//! that directly would serialize the plaintext even when the cipher is
//! real. So the cache uses a private `StoredMessage` whose only body field
//! is `body_ciphertext` (hex). This is the structural half of "encrypted
//! at rest": there is no code path that writes an `EmailMessage` straight
//! to disk.

//! Send pacing and rate limiting for email (Phase C6).
//!
//! Ported from `robius-sms`'s `SendRateLimiter`/`SendPacing` -- the plan
//! (C6) called them out as "already generic arithmetic", and they are: a
//! pure token bucket plus a pure gap schedule, no sleeping, no platform
//! code, so every branch is assertable on a host with no server.
//!
//! ## Why email gets its own copy instead of a shared dep
//!
//! The numbers differ. A carrier silently drops or prompts past ~30 SMS
//! per 30 minutes per app. An SMTP provider rate-limits *harder and more
//! opaquely*: Gmail rejects a burst with a 421/450 and a "too many
//! connections" that the user cannot decode, and consumer relays cap
//! recipients-per-message around 100 (already enforced by
//! `email_send::MAX_RECIPIENTS`). So the bucket and the recommended gap
//! are email-shaped, not carrier-shaped.
//!
//! ## Honest scope
//!
//! The current bulk path sends ONE message to N recipients in a single
//! SMTP transaction, so no per-recipient pacing loop exists yet to wire
//! this into. This module is the primitive: it is tested here, and it is
//! what a future per-recipient batch loop (and the Compose bulk feature)
//! will consume. Nothing claims a pacing loop is already running.

//
// ## Why one slot, not a multi-connection pool
//
// `SEND_IN_FLIGHT` already serialises sends -- at most one send is running
// at a time -- so a pool of N connections would hold N-1 idle sockets for
// nothing. One reused transport per (server, port, username, secret) is
// exactly the right size.
//
// ## What is verified, and what is not
//
// The *keying* decision -- "reuse this transport, or build a new one?" --
// is pure and tested (`should_reuse`). The connection-level reuse itself
// cannot be exercised without a live relay, so it is a read of lettre's
// contract (a transport reconnects lazily on the next `.send`), not an
// observed handshake. The secret is compared by value (never logged) so a
// re-entered password correctly rebuilds the transport instead of reusing

//! The direct-backend IMAP client (Phase C1e).
//!
//! C1 decided to support both backends. The proxy (C1d) is done; this is
//! the other half: reading mail straight from the provider over IMAP.
//!
//! ## The seam, and why it mirrors the proxy
//!
//! IMAP is a stateful raw-TCP protocol: connect, TLS, `LOGIN`, `SELECT
//! INBOX`, `FETCH`. None of that can run in a browser (so this whole
//! module is native-only) and none of it can be host-tested against a
//! real server. So, exactly like `mail_proxy`, the bugs are pushed to the
//! *edges* -- the neutral `FetchedMessage` shape, the date parser, the
//! error mapping -- which ARE pure and tested, while the socket lives
//! behind an `ImapTransport` trait.
//!
//! The real transport (`AsyncImapTransport`) uses `async-imap` and is
//! gated behind the `imap` feature so wasm builds (and builds that do not
//! need IMAP) never pull in its native-TLS dependency tree. See Cargo.toml.
//!
//! ## What is NOT verified
//!
//! No IMAP handshake has been executed here. The trait wiring is proven
//! against a mock; the parser and mapping against fixtures; the socket is
//! a read of async-imap's API. This is stated plainly because the whole
//! point of the remediation was to stop confusing "compiles" with "works".
