Priority 70 sits after RejectListener (77) and before LoginListener (66), and
both bounds are load-bearing:
- After 77 so a rate-limited IP never reaches a ceremony. Passkeys cannot be
used to sidestep a lockout (D3), which is the point of the reviewer's third
clarification.
- Before 66 because LoginListener treats any POST to the auth subdomain as a
login attempt. A ceremony finish body has no username/totp, so Payload::load()
returns null and the request would be scored as a failed login, burning a
rate-limit token for every legitimate passkey login.
Verified in the live container rather than assumed: debug:event-dispatcher
confirms 77 -> 70 -> 66.
Other properties asserted by tests: every header-bearing request gets a JSON
response so fetch() callers never receive HTML; registration identity comes from
the live session, never the request body; a failed ceremony is indistinguishable
from a wrong TOTP code and spends the same shared budget; and begin is bounded
by a separate resource guard that deliberately does not consume failure budget.
The listener also marks its responses so SecurityHeadersListener can apply
no-store: these are the only browser-facing 2xx this application produces, since
the auth subdomain has no forward_auth in front of it. CSP gains
publickey-credentials-get/-create only when passkeys are available, so the
unavailable case stays byte-identical to before.
Groundwork for passkey authentication, with the feature switched off by
default and no behaviour change when it is off.
Decision D1: passkeys require central authentication. A passkey is scoped to
a relying party spanning the base domain, which only exists when
SUBDOMAIN_REDIRECT is on and AUTH_SUBDOMAIN resolves to a base domain. The
RP ID is therefore always that base domain, never the request host.
Decision D4: HTTPS is required and is not exemptible. The allowed origin is
built as https://{authSubdomain} from configuration and never from the
request, so an http:// origin cannot be accepted, and isAvailableFor()
additionally refuses to offer the UI on a non-secure connection. The
deprecated setSecuredRelyingPartyId() escape hatch is not used and there is
deliberately no override that could reintroduce one.
Enabling PASSKEY_ENABLED without a usable configuration is a hard error via
a non-optional cache warmer, because entrypoint.sh runs cache:warmup on every
production boot: a misconfigured deployment fails to start instead of
offering a button that cannot work.
Also drops 12 obsolete phpstan-baseline entries for TotpTestHelper: adding
#[\Override] to its anonymous clock removed the rule violation at its source
rather than suppressing it.
Suite: 333 tests / 770 assertions (was 313 / 738), 100% coverage on new
files. phpstan level 6 clean, php-cs-fixer clean, conformance 35/35.
Brings preauth from 18/34 to 30/34 conformance (auth-gateway profile). The
remaining four checks all depend on files this branch cannot change (see below).
PHP toolchain (§1)
- require.php >=8.4 -> ^8.5, and pin config.platform to 8.5.0. The old
constraint also permitted PHP 9, which is not a promise we can keep.
composer.lock regenerated with --lock: content-hash + platform-overrides
only, zero dependency version movement.
- friendsofphp/php-cs-fixer * -> ^3.95. A wildcard meant CI was not
reproducible.
PHPStan (§2.2)
- vendor the shared phpstan.neon.dist (level 6) + a generated baseline.
187 errors are captured rather than fixed; the baseline should only shrink
from here.
- add phpstan/phpstan:^2.1 to require-dev.
Code style (§8.2)
- vendor the shared .php-cs-fixer.dist.php (@Symfony + @Symfony:risky +
declare_strict_types) and apply it: 59 of 67 files reformatted.
- Verified this is a formatting change, not a behaviour change: all 313 tests
pass after the reformat, all in_array() calls already passed strict=true,
and the remaining edits are @Symfony:risky idiom (yoda conditions, \count(),
self:: over the class name).
Repository layout (§4.4)
- docs/{Caddyfile,compose.yaml,example.env} -> docs/examples/, with
example.env becoming the conventional .env.example. This is the layout
GUIDING-LIGHT already cites preauth as doing correctly — it just needed
renaming.
- update the four readme.md references and a stale compose.yaml comment.
- docs/v1.1-plan.md references are left alone deliberately: it is a historical
plan recording what was done at the time, not live documentation.
Licence and security policy (§7)
- add LICENSE (uniform MIT, matching composer.json).
- add SECURITY.md describing the actual threat model: per-request
allow/intercept, no caching of the login flow, app-set security headers,
TOTP, and the fact that REMOTE_USER is trusted input.
Mobile accessibility (§3.3a)
- templates/base.html.twig: drop maximum-scale=1 and add viewport-fit=cover.
preauth was the one app already past the font-size precondition (controls
render at 21.6px = 0.9em x 24px), so removing the lock is safe here and
restores pinch-zoom for Android users.
Conformance tooling (§8.2)
- vendor .ci/conformance.sh and .ci/css-control-size.py so the check runs
from a checkout rather than fetching from the LAN-only private/ci.
- .editorconfig synced from the version that keeps the Caddyfile tab rule.
Not included (blocked by the .gitea/workflows pre-receive hook):
- ci-composer-audit, ci-composer-validate, ci-reusable-workflows.
Workflow files may only change via a trusted ref, so the caller files are
staged but not committed.
Also not included: dockerfile-nonroot (§6.4). Adding USER to an image with
VOLUME [/config, /data] changes volume ownership and needs an actual container
build/run to verify, so it goes in its own change.
