mixandClaude Opus 5.5 8e3241ef98 audit 3: a restore is ended by its Resync, and half an archive is refused
test / test (push) Canceled after 0s
The restore manifest was consumed as soon as its version was checked,
before store.Open and the Resync; a start that failed in between left a
data directory the next start took for an ordinary one (M1). openData now
runs CheckRestore, store.Open, the Resync, and only then ConsumeRestore.

A truncated archive had nothing to refuse it: the manifest is the first
entry, so a download cut short or a tar stopped by a damaged block was a
restore on half a database. Every archive now ends with data/contents.json,
the size and SHA-256 of each data/ file (deploy files are the operator's to
edit), and CheckRestore compares /data with it before the database is
opened, then renames it contents.checked.json so a start after a failed one
does not compare again unless the manifest changed.

Tests: a start whose Resync fails, then a start that resyncs and consumes;
an archive cut in the database, before the deploy files and in its last
entry (refused, database untouched, no -wal); a damaged key named; the
record's names confined to data/; the domain import of a cut plain export,
a cut and an altered .spde (refused, nothing created). e2e on the test
server: full_backup_restore now also sees contents.json in the archive and
gone after the first start, through the real entrypoint and daemons (all
pass, 762 s); go vet + go test of 24 packages pass there.

mixandClaude Opus 5.5 ef18ef21a0 findings of the reviews of audit stage 2
test / test (push) Canceled after 0s
Technical review (Opus) and security review (Fable) of a59e3d4..cb5a4a2;
reports in the session's scratchpad. Nothing critical, high or medium; no
outright bug. Fixed:

- F2, F3 (0008 backfill, before it runs on the live database): rows are
  filled by the rule new rows follow - the application's domain, then the
  name's - and only by a domain and application that existed when the row
  was written (created_at); the inbound log likewise. Test: the migration's
  UPDATEs re-run on prepared rows (before the domain, after, null sender,
  application gone, a stranger's name). Dry run on a copy of the live
  database: 68/68 and 10/10 rows filled, none disagreeing with its login's
  domain, integrity ok.
- V2, F4: an application's statistics and level-2 count are its login's
  rows of its domain (appByLogin), and StatsWindow starts no earlier than
  the entity's creation; the message page's "may send as" only for a login
  still of the row's domain. Test: a login taken again in another domain
  starts at zero.
- F7: MAIL FROM:<> is held to the domain limit of its login
  (ApplicationByLogin fills DomainName).
- V3: an imported DKIM selector is held to DNS labels (validate.Selector).
- F5, F6: an imported auto limit's numbers are dropped and recalculated
  right after the import; its mode is stored trimmed.
- V6: the store refuses a role that is neither global nor domain.
- F9: SaveUser keeps the stored hash when no new password is given (the
  form no longer writes back the hash it read). F10: a reach naming a
  domain deleted meanwhile is ErrNoSuchDomain, answered on the form.
- V4, F12: from-lines-other.txt - lines naming another sender ({other}) in
  a quoted string, a quoted pair, capitals, a comment, an encoded word, a
  quoted local part; the unit test wants each refused, the e2e
  (lines_naming_another_sender_never_signed_for_it) wants each refused and
  none signed for it. The passed list gained a.{DOMAIN}, a comment after
  the angle address, a quoted local part, and "b@ {other}" - passed by
  design (security.md), and the e2e shows it signed for the own domain.
- F13: e2e login_in_other_capitals_does_not_authenticate - AUTH with the
  login upper-cased gets 535.

Not changed, written down: V1/F1 - L8 is half closed (refused or passed
still tells an application which domains are hosted here); security.md's
accepted risks and the CHANGELOG say so, and the owner is asked whether to
refuse every foreign address in a display name (changes the 2.4.0 rule).
F11 - deleting a domain rewrites its rows' domain_id (seconds at 1e5 rows),
accepted at this size. F8 (test cannot tell write-first from read-first;
the reviewer verified it with two stores, 30/30), V5, V7, P2: noted.

Evidence on the test server for this tree: go vet clean, go test ./... 23
packages ok, make e2e exit 0 with the three new cases.

mixandClaude Opus 5.5 e469034477 import: the export file held to the forms' rules before anything is created (audit M10)
test / test (push) Canceled after 0s
domain.Import trusted the file for everything but the domain name, the
selector and the password: DMARCRua was not validate.Email'ed, client IPs
not parsed, a rate limit's mode, window and count not checked - a window of
0 counted nothing, a garbage IP made the application refuse every client.

handlers.checkDomainImport runs in HandleImportDomain after the domain name
check and before Import, and refuses the file with "Invalid <what> in export
file: <the form's own text>": the report address (validate.Email), each
rate limit (parseRateLimitMode; auto - checkAutoMultiplier, 0 meaning the
default as an empty field does; manual - checkManualLimit, which the form
now uses too: count > 0, <= the level-1 backstop, window > 0; both 0 is an
export without a limit of its own), each application's client addresses
and the legacy ones on its rate limit (parseIPList, written back as the
form stores them; allow-list on with none is refused). Login, sending
addresses and password stay checked in app.ImportApplication.

Tests: a good export passes and its addresses come out normalised; nine
broken fields each refused with their message; a refused file posted to the
handler creates no domain.

CHANGELOG [Unreleased], audit plan line ticked, roadmap 18/62.
Evidence: go vet clean; the import, rate-limit and application tests of
./internal/web/handlers ok; the server run follows before the push.
