-# The build, and that every test target compiles. It deliberately does not
-# *run* the test suites: the unit tests only build with the integration crate
-# in the graph, because that is what switches on the `test_mode` features they
-# rely on (docs/spec/SPEC.md 2.2b), and the integration suites need a `STORE`,
-# fixed ports, and in most cases a container apiece (docs/spec/
-# container-tests.md). Running them here would mean either a green tick that
-# skipped everything, or a red one that means "the runner has no Redis".
+# Gitea (git.coffeylabs.org) is where this project lives: pull requests,
+# issues, releases and the container registry are all there, and it pushes
+# every branch and tag to this GitHub copy as it changes. GitHub's hosted
+# runners are faster than the self-hosted ones -- and have native arm64 -- so
+# the building happens here, and the answer goes back to Gitea as a commit
+# status that Gitea's own ci.yml / publish.yml wait on.
 #
-# So this catches what it can honestly catch -- code that does not compile,
-# including test code -- and the suites are run by hand, one at a time, as
-# that page describes. If that changes, it changes because someone made the

-# Publish the container image to GHCR.
-#
-# The README and the docs site have told people to run
-# `ghcr.io/inbuxa/inbuxa-server:latest` for a long time, and nothing ever
-# pushed it: `docker pull` answered `denied`, because the package did not
-# exist. This is the workflow that makes those instructions true. It is also
-# the prerequisite for the self-hosted app catalogs -- TrueNAS and Unraid
-# both install by pulling an image and neither builds from source.
-#
-# FIRST RUN: a package GHCR creates for the first time is **private**, even in
-# a public repository, and an anonymous `docker pull` will still answer
-# `denied`. Nothing in a workflow can change that -- the visibility is set once
-# by hand under the package's settings, and until it is, this looks like it
-# worked while the docs stay just as wrong as before. Check with a logged-out
-# pull, not with one from a machine that has credentials.
-#
-# Two architectures, each built on its own native runner rather than under
-# QEMU. Emulated arm64 has to run `npm ci` and the Vite build through
-# instruction translation, which takes tens of minutes and occasionally runs
-# out of memory; `ubuntu-24.04-arm` is free for public repositories and does
-# the same work at native speed. The cost is the by-digest dance below: each
-# runner pushes an untagged image, and a final job joins the two digests into
-# one multi-arch tag.

+//! - `inbuxa:JournalEntry/query` and `/get`: searching and reading what was
+//!   journaled (`sysJournalSearch`). `report` is the whole journal report,
+//!   only when asked for.
+//! - `inbuxa:JournalExport/set`: a ZIP of the reports a filter matches, in
+//!   the hold export's shape (`sysJournalExport`).
+//! - `inbuxa:JournalVerification/set`: rechecks every chain and every report

+### Passwords over HTTP
+
+- **C-23.** **Outside DAV, HTTP sign-in is a token, never a password.** JMAP
+  (`/jmap`, with session, upload, download, event source and WebSocket), the
+  management API (`/api`), and the OAuth endpoints that authenticate a user
+  (`/auth/introspect`, `/auth/userinfo`, authenticated `/auth/register`)
+  refuse an `Authorization: Basic` header with a 401 whose only challenge is
+  `Bearer`, and don't check the password. CalDAV and CardDAV (`/dav`) keep
+  Basic, since that's how calendar and contacts apps sign in, and their 401s
+  still offer it. The sign-in page's own endpoint (`/api/auth`) takes the
+  password in its body, not a header, and isn't affected. Neither is the token
+  endpoint's client authentication. SCIM already takes an API key only.
+  Bootstrap and recovery mode accept Basic everywhere, as they keep
+  permissive CORS (C-16).
+  **Decision**: without this, anyone can put up a copy of a front end on a
+  server of their own that collects a person's password and replays it as
+  Basic. Cross-origin rules (C-14) don't stop that, because a server isn't a
+  browser, and neither does client registration (C-5), because Basic never
+  goes through OAuth. With C-23, the password only goes to the server's own
+  sign-in page (C-8), or to a DAV client or mail app the person set up
+  themselves.
+  An operator who needs Basic on every endpoint sets
+  `INBUXA_HTTP_BASIC_AUTH=all`; `dav`, the default, is this rule. Any other
+  value logs a warning and keeps the default. The setting moves to the
+  registry with `x:FrontEnds` (C-4).
+  ihasmail-inbuxa confirms a typed password, which it does before creating
+  an app password, on `/api/auth` as its own client, to its registered
+  redirect URI, with a PKCE challenge whose verifier it discards. A
+  "two-factor code needed" answer counts as confirmed, since the server gives
+  it only after the password matched.
+  **Built, 2026-09-29.** `crates/http/src/auth/token_only.rs` names the
+  paths; `request.rs` refuses before routing and picks the 401's challenge by
+  path; `Http.basic_auth_everywhere` holds the setting. Test builds
+  (`test_mode`) accept Basic everywhere, since the integration suites sign in
+  with passwords. Checked by `tests/e2e/http_basic_auth.py` against the debug
+  build, 26 checks: everything above, both front ends' sign-in path, a wrong
+  password answered exactly as the right one, and a redirect URI the webmail
+  didn't register refused.
+  Observed before the change, in INBUXA's production logs from 2026-09-20 to 2026-09-29:
+  every HTTPS password sign-in was the operator's own, apart from
+  ihasmail-inbuxa's password sign-in on 2026-09-22, before it moved to OAuth.
+  The logs don't say whether a sign-in used a Basic header or the sign-in

-Unmatched mail writes nothing.
+**As built (phase 2f).** The actor is the sender (they sent it; filtering by
+sender is what a reviewer wants), the action `create`, the target kind
+`message`. The details say what happened, where to, and each rule with its
+detectors' counts: `DLP warned, to elsewhere.org: "Cards leaving"

+(`inbuxa:dlpBlocked`, `inbuxa:dlpWarning`); an override as a success, with
+the sender's reason. No new audit action was added: an older node reading a
+record with an action it doesn't know fails its daily clean-up, so a new
+action would make rolling back unsafe.
+
+Transport rules that refuse a message or change where it goes (redirect, add
+a recipient, route) record the rule and what it did the same way, the actor
+being the sender, or `system:mail-flow` for incoming mail. **As built
+(phase 2g)**, rules that only change wording or headers (a disclaimer, a
+header, a subject prefix) write nothing: a banner rule would otherwise write

+
+## What it is
+
+A **journal** is a copy of each message the server handles, captured in
+transit with its **envelope** (the real sender and every recipient, including
+Bcc and the members of lists), kept where nobody can change or remove it
+until its retention ends, or sent to an outside archive. It sits beside two
+things that exist:
+
+- **Legal hold** keeps what's in chosen mailboxes, including what their owners
+  delete. It starts when a hold is placed and can't see Bcc or what was sent
+  from a mailbox that no longer exists.
+- **The audit log** records what people and the server did, never the mail.
+
+A journal answers the question neither can: *what went through, to whom,
+from the day it was turned on*.
+
+**Out of scope**: journaling mail stored before it's turned on, files,
+calendar and contacts, IMAP APPEND (a mail app saving to its own Sent folder
+sends nothing), and mail a mail app sends through another server.
+
+Nothing in code, docs, UI text or output claims the product meets a legal or
+regulatory standard. The pages say what's captured, where it's kept and for
+how long.

+## 1. What exists today

+|---|---|
+| One place all mail passes | `MessageWrapper::queue` (`queue/spool.rs` ~L375). SMTP, JMAP submission (`jmap/src/submission/set.rs` builds a local session and runs `queue_message`), inbound mail, Sieve redirects and vacation replies, and DSNs all queue through it. Local and remote delivery both start from the queue. |
+| The envelope | At queue time: `mail_from`, every `rcpt_to` (Bcc included), the authenticated account with its groups and tenant, the queue id. Lists are **already expanded** at RCPT (`rcpt_resolve` → `RcptResolution::Expand`, `inbound/rcpt.rs`); the list address survives as each member's ORCPT (`dsn_info`). |
+| A copy out | Sieve at DATA, milters and MTA hooks can send one, but all run **before** DLP and transport rules, so they miss recipients the rules add, and a Sieve copy carries no envelope. |
+| Keeping a blob nobody can delete | No "undeletable" flag. Blobs are content-addressed (can't be edited); a `BlobLink::Temporary { until }` keeps one until `until`. Legal hold uses `until` = year 9999. |
+| A record nobody can quietly change | The audit log's per-node SHA-256 chain (`features/src/audit/log.rs`): each entry carries `prev`, the head is asserted on append, purge leaves a floor hash, `verify` walks it. |
+| Export | Hold export (LH-12): a ZIP of `.eml` files, `manifest.csv` with a SHA-256 per file, `manifest.sha256`, capped at 2 GiB. |
+| Conditions by sender, recipient, group, tenant | The mail flow engine (`features/src/mailflow/engine.rs`), at DATA. |
+
+## 2. Design
+
+### 2.1 Where the copy is taken (JR-1, JR-2)
+
+**JR-1.** The journal is taken in `MessageWrapper::queue`, after the message
+is spooled, behind one `// inbuxa:` marked block. That's after DLP and
+transport rules, so the envelope is the one the message actually leaves or
+arrives with, and it covers every path that queues mail.
+
+**JR-2.** What isn't journaled: journal reports themselves (they carry a
+queue flag, so a report to an outside archive can't journal itself), and the
+server's own DMARC and TLS reports. DSNs and Sieve redirects and vacation
+replies are journaled (question 4). A message **refused** at DATA (DLP block,
+a transport rule's refusal) was never accepted and isn't journaled; the
+audit log already records it. A message **held** for DLP review is journaled
+when it's queued, which is when it's held, with the hold noted in the entry.
+
+### 2.2 The journal report (JR-3, JR-4)
+
+**JR-3.** Each copy is a **journal report**: a new message whose first part
+is `text/plain`, one field a line:
+
+```
+Sender: alice@example.com
+Signed in as: alice@example.com
+Subject: Q3 figures
+Message-ID: <…>
+Queue ID: 1a2b3c…
+Received: 2026-09-28T14:03:11Z
+Direction: outgoing
+To: bank@elsewhere.example
+Cc: bob@example.com
+Bcc: carol@example.com
+Expanded: finance@example.com -> dan@example.com, erin@example.com
+Held for review: yes
+```
+
+and whose second part is the message as queued, **byte for byte**, as
+`message/rfc822`. `Bcc:` lists envelope recipients that aren't in the
+message's To or Cc headers. `Expanded:` groups the members of a list under
+the list address, from their ORCPT. Recipients a transport rule added say so
+(`Added by rule: <name>`). The field names are fixed English (they're a
+record, not interface text), so a script can read them.
+
+**JR-4.** One report per queued message, with the whole envelope, whatever
+the scope matched on (§2.4). A message to 40 recipients is one report, not
+40.
+
+### 2.3 Where reports go (JR-5 to JR-8)
+
+Each journal has a **destination** (question 1):
+
+**JR-5. The built-in journal.** Records under a new prefix `J` in
+`SUBSPACE_INBUXA`: queue id, received time, direction, sender, recipients,
+the tenant(s), which journal matched, the report's blob hash and size, its
+SHA-256, and the time it may be purged. The report blob is kept by a
+`BlobLink::Temporary { until }` set to the end of its retention. There is no
+JMAP `set` or `destroy` for entries: nothing in the product changes or
+removes one before its time.
+
+**JR-6. The chain.** Each entry carries the SHA-256 of the entry before it,
+one chain per node, the same construction as the audit log (and its code,
+generalized rather than copied). The console's **Check the journal** walks
+it, and every blob's hash against its entry, and says what it found. Someone
+with the server's disks can still remove data, and the chain is how that
+shows; the docs say exactly that, and don't say it can't happen.
+
+**JR-7. An outside archive.** The report is queued to an address (the
+archive's journal mailbox) like any mail, with the queue's retries. A report
+the archive refuses permanently, or can't take within the queue's limit, goes
+into the built-in journal instead and raises a warning on the Overview
+(question 6). Delivery is by the ordinary queue, so TLS and routing settings
+apply; a queue route can be chosen for it.
+
+**JR-8. Both**: the built-in journal and an outside archive.
+
+### 2.4 Which mail: journals and their scope (JR-9 to JR-11)
+
+**JR-9.** A **journal** is a named object (`inbuxa:Journal`): on or off, a
+destination, a retention, and a scope. The scope is who: **everyone**, or
+senders and recipients in chosen **accounts, groups, domains or tenants**,
+and which **direction**: outgoing, incoming, internal, any. A message is
+journaled once per journal whose scope any sender or recipient is in; two
+journals with the same destination never write the same message twice.
+
+**JR-10.** **By what's in it**: a new mail flow rule action, **Journal it**,
+names a journal. The rule's conditions (detectors, words, attachments,
+headers) decide; the copy is still taken at queue time (the rule only marks
+the message). This is the rule-based journaling the queue note called
+premium; here it's one more action, not a separate tier (question 2).
+
+**JR-11.** Scope is evaluated from the envelope and directory membership at
+queue time (`Server::member_of`), no message parsing, so journaling
+everything costs a lookup per recipient and one blob write per message.
+
+### 2.5 Retention and legal hold (JR-12 to JR-14)
+
+**JR-12.** Each journal has a retention in days (question 3). An entry keeps
+the retention it was written with: shortening a journal's retention applies
+to new entries only, so nobody can empty the journal by editing a number.
+Lengthening it applies to new entries too, and the console says so.
+
+**JR-13.** Purge runs in the daily maintenance, removes entries past their
+time and drops their blob link, and leaves a floor hash so the chain still
+verifies, as the audit log does. An entry whose sender or any recipient is
+under a **legal hold** isn't purged while the hold lasts (`holds_on`, read
+uncached, as holds are everywhere).
+
+**JR-14.** Deleting an account doesn't remove its journal entries; they end
+with their retention (question 7). The privacy catalog says so.
+
+### 2.6 Search, reading, export (JR-15 to JR-17)
+
+**JR-15.** **Management › Compliance › Journal**: search by sender,
+recipient, date range, direction, subject words (from the report's header
+fields, not the body: no full-text index of the journal in this version).
+Results list the envelope; **Read…** opens the report.
+
+**JR-16.** **Export** a search as a ZIP in the hold export's shape: the
+reports as `.eml`, `manifest.csv` with the envelope columns and a SHA-256
+per file, `manifest.sha256`, the same 2 GiB cap. Export runs as a task and
+the result is a blob owned by the person who asked for it.
+
+**JR-17.** Every search, read and export is in the audit log, with who and
+the search terms; so is every change to a journal.
+
+### 2.7 Permissions (JR-18)
+
+**JR-18.** New permissions after the DLP set (680 onward):
+`sysJournalGet` / `sysJournalUpdate` (see and change journals),
+`sysJournalSearch` (search and read entries), `sysJournalExport`. Superuser
+only, by default. The officer grant audience adds Get, Search and Export to
+the Compliance Officer; administrators configure journals but don't read
+them unless granted Search (question 5). Journals are server-level, with a
+tenant scope, as DLP rules are; nobody in a tenant reaches them.
+
+### 2.8 Privacy catalog
+
+New objects get catalog entries (`resources/privacy/catalog.toml`):
+`inbuxa:Journal` (none), `inbuxa:JournalEntry` (mail content and envelope,
+kept for the journal's retention, access audited, not erased with the
+account). `privacy-check.py` enforces it.
+
+### 2.9 Mixed versions, clusters, rollback
+
+- Entries and journals live in the shared data store; report blobs in the
+  blob store. A **node-local** blob store (FileSystem, or RocksDB/SQLite as
+  the blob store) on a cluster means a node's journal lives on that node;
+  the console warns when journaling is on and the blob store isn't shared.
+- During a rolling upgrade a node on the old version doesn't journal. The
+  console says so when nodes report different versions; the release notes
+  say to turn journals on after every node is upgraded.
+- Rollback: the new prefix and the queue flag are ignored by an older
+  version; nothing in the queue's archived format changes (the "journal
+  report" flag rides in the existing message flags if one is free, else in
+  a side key by queue id; checked in phase 2 before writing code).
+
+### 2.10 Cost
+
+One extra blob per journaled message (the report wraps the original, so it
+doesn't share its hash), plus one small record. The console shows the
+journal's size and growth per day on the journal page, from the entries.
+
+## 3. Console
+
+- **Management › Compliance › Journaling**: journals (name, scope,
+  destination, retention, on/off), described in words like DLP rules
+  ("Journal all mail to and from Finance into the built-in journal, kept
+  7 years"); **Check the journal**.
+- **Management › Compliance › Journal**: search, read, export.
+- The mail flow rule editor gains **Journal it**.
+- The Overview warns about undelivered outside reports (JR-7) and a
+  node-local blob store (§2.9).
+
+## 4. Webmail
+
+Nothing. People aren't told a message was journaled, as they aren't told
+about legal hold; the docs say journaling exists and what it captures.
+
+## 5. Tests
+
+Unit: the report's fields (Bcc computed from headers, list expansion from
+ORCPT, rule-added recipients), scope matching, retention arithmetic, the
+chain. Integration (`tests/src/system/`): SMTP and JMAP sends, inbound
+mail, internal mail, a list and a Bcc recipient, a DLP-held message, a
+Sieve redirect; the report equals the queued bytes; no `set`/`destroy`;
+shortening retention doesn't touch existing entries; a hold stops purge;
+account deletion leaves entries; an outside archive that refuses falls back
+to the built-in journal; export manifest hashes; audit records for search,
+read, export.
+
+## 6. Phases
+
+1. This spec, approved.
+2. Capture at the queue, the report, the built-in journal with its chain,
+   retention and purge, holds; `inbuxa:Journal` and `inbuxa:JournalEntry`;
+   catalog entries; tests.
+3. Outside archive and the fallback; **Journal it** in mail flow rules.
+4. Search, read and export (a task), audit records.
+5. Console pages; docs; a row in `inbuxa-drafts/divergence-log.md`.
+
+Each phase is its own PR with tests; releases as John decides. Like DLP, it
+stays out of production until John says.
+
+## As built
+
+Phase 2 (`feature/journal-capture`), where it differs from the design or
+fills in what it left open:
+
+- **The chain** is the journal's own (`crates/features/src/journal/
+  entries.rs`), not the audit log's code shared. Entries expire out of chain
+  order (each keeps its journal's retention, and holds keep some longer), so
+  a link names its entry by SHA-256 instead of holding it: purging removes
+  the entry, its indexes and its report's blob link, and writes a purge
+  marker; the link stays. An entry missing without a marker is a broken
+  chain. Purged links at a chain's start are cleared and a floor recorded,
+  as the audit log does.
+- **If the copy can't be taken**, the message isn't queued: the sender gets
+  a temporary failure and tries again. Nothing leaves unjournaled.
+- **The report** says `Authenticated: yes|no` instead of the signed-in
+  account (the queue doesn't keep which account it was). `Added by rule`
+  comes with **Journal it** in phase 3. A recipient given with an ORCPT
+  that names another address counts as expanded from that address.
+- **Journal reports** the server queues carry message flag bit 48
+  (`FROM_JOURNAL`); an older version ignores the bit.
+- **Permissions 680–683**: administrators get `sysJournalGet`/`Update`; the
+  Compliance Officer gets `Get`, `Search` and `Export`. So that an
+  administrator can still appoint an officer (and grant reading as settled
+  answer 5 describes), whoever holds `sysJournalUpdate` may grant `Search`
+  and `Export` without holding them; the role change is in the audit log.
+- **`inbuxa:JournalEntry`** (get, query) and **Check the journal** over
+  JMAP come in phase 4 with search, so every read is audited from the first
+  version that allows one. Phase 2 has `inbuxa:Journal` only.
+
+Phase 3 (`feature/journal-archive`):
+
+- **Destinations** are two properties of a journal: `builtIn` (true for
+  journals stored before phase 3) and `archiveAddress`. At least one.
+- **Journals only rules use**: a journal whose scope chooses nobody takes
+  only what a **Journal it** action sends it. The action goes on mail flow
+  rules, and on a DLP rule beside its block, warn or hold (a blocked
+  message isn't queued, so it isn't journaled).
+- **Reports to an archive** are queued from the empty sender, so a refusal
+  comes back to no one; a pending record per report says what to keep.
+  When the queue lets go of a report without delivering it (refused,
+  expired, or deleted from the queue), the report becomes its own entry in
+  the built-in journal under the sending journals' retention, even when
+  another journal already kept the message there, the journal's
+  `archiveFailures` (count, last time, reason) goes up, and the audit log
+  records it. If that can't be written, the report stays queued.
+- **Added by rule** lists recipients a transport rule added or redirected
+  to, by rule name, instead of counting them as Bcc.
+- A rule's route (and now its journal marks) is cleared between messages
+  in one SMTP session; before, a second message in the same session kept
+  the first one's route.
+
+Phase 4 (`feature/journal-search`):
+
+- `inbuxa:JournalEntry/query` (after, before, sender, recipient, address,
+  direction, subject words, Message-ID, journal; newest first, pages of up
+  to 500) and `/get` (`report`, the whole journal report up to 10 MB of
+  text, only when asked for), with `sysJournalSearch`.
+- Recording (JR-17) happens before anything is returned, and nothing is
+  returned if it can't be written: a search with its terms, a listing
+  once per call, each report read on its own (as `blobAccess`, the
+  action reads of someone's mail already use), each export with its
+  reason (`export`), each check (`verify`). No new audit actions, so an
+  older version reads every record.
+- `inbuxa:JournalExport/set` builds the ZIP in the request, like the audit
+  log's export, rather than as a task: at most 10,000 reports and 1 GB,
+  and a search that matches more is refused with the count, to narrow.
+  The ZIP has the reports as `.eml`, `manifest.csv` with the envelope and
+  a SHA-256 per file, `exceptions.csv` for reports that couldn't be read,
+  and `manifest.sha256`.
+- `inbuxa:JournalVerification/set` rechecks the chains and every report
+  against its entry, with `sysJournalGet`.
+
+Phase 5 (inbuxa-admin #62, server #119 for the menu, docs inbuxa.org #32):
+
+- One console page, **Management › Compliance › Journal**, with two tabs
+  instead of the two pages §3 named: **Search** (for those who may search)
+  and **Journals** (the editor, on/off, delete, archive warnings, and Check
+  the journal).
+- The warnings §3 put on the Overview (undelivered archive reports, a
+  node-local blob store) aren't there: archive failures show on each
+  journal, and there's no blob-store warning yet.
+- The rule editor's **Journal it**, on mail flow rules and as an optional
+  second action on DLP rules.
+
+## Known gaps
+
+- A message a person saves to Sent over IMAP, or sends through another
+  server, never reaches the queue.
+- Mail stored before journaling is on isn't journaled (legal hold covers
+  mailboxes).
+- Search reads envelope and header fields, not bodies.
+- Group accounts (`GroupAccount`) resolve as one account, not members; their
+  mail is journaled under the group's address.
+
+## Settled
+
+John, 2026-09-28, all seven as recommended:
+
+1. **Destinations**: the built-in journal, an outside archive by address, or
+   both, per journal (JR-5, JR-7, JR-8).
+2. **Scope**: everyone, or chosen accounts, groups, domains and tenants by
+   direction, plus a **Journal it** rule action; no standard/premium split
+   (JR-9, JR-10).
+3. **Retention**: no default; 30 days to 10 years, picked when a journal is
+   turned on; existing entries keep theirs (JR-12).
+4. **Which mail**: everything queued, including DSNs, Sieve redirects and
+   vacation replies, except DMARC/TLS reports and journal reports (JR-2).
+5. **Who reads it**: administrators configure; Compliance Officers search,
+   read and export; administrators read only if granted Search (JR-18).
+6. **An outside archive that won't take a report**: kept in the built-in
+   journal, with a warning (JR-7).
+7. **Deleted accounts**: journal entries stay until their retention ends,
+   and the catalog says so (JR-14).

+Administrators hold OAuthClientOverride. Upstream lets it skip the client and

+- after setup, an administrator gets no code for an unregistered client, nor
+  for a registered one with a redirect URI it didn't register, while the

+- a device code an administrator approves for an unregistered client can't be

+"""Local end-to-end check of contract C-23: outside DAV, HTTP sign-in is a
+token, never a password.
+
+Run it with `python3 tests/e2e/http_basic_auth.py` after
+`cargo build -p inbuxa`. Needs Docker. Working state goes under target/e2e.
+
+Boots the debug binary and checks that:
+- in bootstrap mode, Basic works on JMAP (as permissive CORS does, C-16);
+- after setup, Basic is refused on JMAP, the API, userinfo and introspection,
+  with a 401 that offers only Bearer, and the password isn't checked;
+- DAV still takes Basic, and its 401 still offers it;
+- a token from the sign-in endpoint (`/api/auth`, the password in the body)
+  and the token endpoint works on JMAP: the path the front ends use, and the
+  one ihasmail-inbuxa's password check relies on;
+- INBUXA_HTTP_BASIC_AUTH=all puts Basic back everywhere, an unknown value
+  keeps the default with a warning, and recovery mode accepts Basic.
+
+Passwords are generated into files under target/e2e and never printed.
+Everything is removed afterwards unless KEEP=1.
