Read a mailbox read-only, in a client small enough to audit (#246)

internal/email is the reading half of the email reader: a ~200-line IMAP
client (LOGIN, EXAMINE, UID SEARCH SINCE, UID FETCH BODY.PEEK, LOGOUT), a
MIME-to-plaintext converter, and a header-only junk filter.

Two protocol choices are the design, not shortcuts. EXAMINE instead of
SELECT means the session is read-only at the protocol level, so no command
in it can flip a flag or expunge anything by mistake. BODY.PEEK instead of
BODY means reading a message does not mark it \Seen — Maven reads his mail
and leaves no trace of having done so, and the unread state in his own
client stays his.

Hand-rolled rather than go-imap because this is the one path that holds his
mailbox credential and reads his private mail: five commands with no
dependencies is auditable in a sitting. No IDLE and no cleartext/STARTTLS
either — an option to send his password over a plain socket is an option to
get it wrong once.

Junk is decided by headers alone, before any model is involved:
List-Unsubscribe/List-Id, Precedence: bulk, Auto-Submitted, the spam
headers, and Gmail's own category labels. Sender lists and subject keywords
are deliberately absent — they age badly and they would put his contacts in
a config file. A junk verdict only means "do not spend the model on this";
nothing is deleted and no server flag is touched.

Nothing here logs a body, a subject or an address, the junk reason names a
header rather than content, and an undecodable charset degrades to
headers-only instead of feeding the model mojibake. Verified against
recorded .eml fixtures and an in-process fake IMAP server.

 6. Wire voice query — `"что я обычно делаю?"` routes to `IntentQuery` → behavior profile lookup → LLM-phrased answer
 7. Add IPC read method `MethodGetBehaviorProfile` so mavweb can display it on `/dash`
 8. Test with synthetic fact history — verify weekly schedule is correctly inferred
+
+---
+
+## Status (2026-08-01) — partially shipped, deliberately narrowed
+
+Shipped on `overnight/behavior-profile`:
+
+- `internal/memory/behavior.go` — `BuildProfile` counts habits per weekday out of
+  self-facts: distinct-day counts (`MinHabitDays = 2`), a median time-of-day, and
+  `FormatWeekdayRU` / `FormatOverallRU` for the spoken answer.
+- `internal/router/habit.go` — `ParseHabitQuery`, which requires a habit marker
+  ("обычно", "каждую", "привычки", …) and parses the weekday deterministically.
+- `cmd/mavend/actions_query.go` — a `habits` query source, so "что я обычно делаю
+  по вторникам?" is answered.
+
+**Not shipped, and not to be shipped as written:**
+
+- *Step 3, LLM-generated profile stored as a fact.* The profile is COUNTED, not
+  generated. A 1.7B asked to summarise a year of habits produces fluent claims
+  about the owner's life that no row supports, and a wrong claim about him is the
+  most expensive kind of wrong maven can be. Counting is verifiable and cheap.
+- *Step 5, incremental updates on fact write.* There is no cache to keep fresh —
+  the profile is recomputed on the question, so a new fact is already in the next
+  answer. A cached profile that can disagree with its own rows is two truths.
+- *Step 4, proactive daily plan proposals via the dispatcher.* Maven is not a nag,
+  and a nudge at 08:00 every day proposing the day is the definition of one. The
+  sanctioned path from "she noticed a pattern" to "she acts on it" already exists:
+  `internal/pattern/detector.go` proposes a routine, and the owner accepts it on
+  `/routines`. It goes through him.
+
+Still open, if wanted later: `MethodGetBehaviorProfile` + a `/dash` panel (step 7).
+The counted profile needs no new IPC method to be *asked* about — the query source
+reads `RecentFacts` over the existing surface — so this is a display concern only.
