Only archived job data and internal-store node-list data honoured the
selected resample algorithm. For running jobs the algorithm was dropped:
MetricDataRepository.LoadData had no such parameter, so the memory store
fell back to an empty string, which cc-lib's GetResampler maps to LTTB.
The external store client was worse - its APIQueryRequest had no
ResampleAlgo field at all, and LoadNodeListData accepted the parameter
without using it.
Add resampleAlgo to the LoadData interface (mirroring LoadNodeListData),
forward it from metricdispatch, and set it on both stores' requests. The
field is tagged omitempty, so the wire format is unchanged when empty -
verify the deployed cc-metric-store accepts it before relying on it there.
The REST job endpoints pass a non-zero resolution and therefore do
resample, so they now request the configured default instead of an empty
string. Add config.ResampleAlgo() for that, since "" is not a neutral
value at this layer.

The policy -> target-points mapping existed twice with different values:
internal/config (300/600/1000) fed the resampler's MinimumRequiredPoints
threshold, while internal/metricdispatch (200/500/1000) fed the requested
resolution and the frontend target point count.
Because the threshold was larger than the target, the resampler refused to
downsample series whose length fell between the two numbers, silently
dropping the resolution the backend had asked for. With the medium policy
that covered every series between 500 and 600 points.
Move the table into internal/config as the single source of truth (import
direction rules out the reverse, since metricdispatch already imports
config) and keep the 200/500/1000 values, which already drove the requested
resolution. metricdispatch.TargetPointsForPolicy now delegates to it, so
MinimumRequiredPoints equals the target and resampling happens exactly when
a series exceeds it.

Pre-existing formatting drift picked up by `make fmt`. Whitespace and
comment layout only, no semantic change.

Resolve conflicts in the generated GraphQL code by regenerating it against
the merged schema. cc-lib v2.13.0 adds Tooltip to schema.MetricConfig and
schema.GlobalMetricListItem, so gqlgen now binds the tooltip field directly
and the hand-written globalMetricListItem/metricConfig resolvers introduced
on the tooltip branch are no longer needed.
Also migrate to the cc-lib v2.13.0 metric container types, which changed
from bare maps to structs carrying array-valued metric groups:
schema.JobData map -> {Metrics, Groups}
schema.ScopedJobStats map -> {Metrics, Groups}
job.Statistics map -> schema.JobStatisticsSet{Metrics, Groups}
Callers index .Metrics, return the zero struct instead of nil, and
deepCopy/DecodeJobStats now also carry the Groups payload through.
archive.GetStatistics returns the full JobStatisticsSet so group
statistics survive the round trip.

OIDC roles were translated by a hardcoded switch that only recognised the
literal names user/admin/manager/support (dropping api) and required the
IdP to emit exactly those names.
Add an optional auth.oidc.role-mapping (OIDC role/group claim value -> CC
role) so operators can map their own realm/client role names, including
api. The mapping is the sole source of roles: only mapped names are
honored, unmapped token roles are ignored, and users without any mapped
role receive the base "user" role. Mapping targets are validated once at
startup. Role assignment stays authoritative on every login as before.
Note: deployments relying on the IdP emitting literal CC role names must
now map them explicitly (e.g. "admin": "admin").

The LDAP sync only ever granted the base "user" role. Add an optional
auth.ldap.role-filters map (role -> LDAP filter) so accounts matching a
filter are granted that elevated role (admin/support/api/manager).
LDAP is authoritative for the configured roles: sync both adds and removes
them to match group membership, while roles not listed (e.g. a manually
granted manager) are preserved. A managed manager that still has assigned
projects is never stripped. With no role-filters configured behaviour is
identical to before.
Roles are reconciled during periodic sync and at login. Sync evaluates
each filter once over the whole base (one search per role, not per user)
and reconciles existing users via a single ListUsers lookup plus the new
UserRepository.UpdateRoles helper.

Add a "main.footer-links" config option so the footer Imprint and
Privacy Policy links can point at internal pages (default) or external
URLs. External http(s) targets open in a new tab; empty/unset values
fall back to the built-in /imprint and /privacy routes, keeping the
existing ./var/*.tmpl override mechanism intact.

Secrets (JWT keys, LDAP sync password, OIDC client id/secret, cross-login
keys) are now configured directly in config.json under the auth section
where they are used. Each secret can still be supplied via its existing
environment variable, which takes precedence over the config value.
The godotenv dependency, the .env file, configs/env-template.txt and the
loadEnvironment() bootstrap step are removed. -init now writes the demo
JWT keys into config.json instead of a .env file.

Browser sessions are now server-side, stored in the SQLite database via
scs/sqlite3store (new `sessions` table, DB migration to version 12) instead
of gorilla/sessions client-side cookie storage. Only an opaque random token
is kept in the cookie; session data lives server-side and survives restarts.
Session middleware is wired as a hybrid to avoid buffering large responses:
scs.LoadAndSave on the login/logout write paths, and a non-buffering
read-only LoadSession middleware on the secured/config/frontend read paths
so the large GraphQL /query responses stream unbuffered. JWT-only APIs
(/api, /userapi, /api/metricstore) and static files are left unwrapped.
The session cookie Secure flag is now derived from the server config (set
when cc-backend terminates TLS itself); previously it was effectively never
set. The SESSION_KEY env var is removed as server-side tokens need no
signing secret. The dormant Bearer-JWT branch in the frontend urql client
is removed; the web UI authenticates GraphQL via the session cookie.

- auth: do not abort the server when authentication is disabled. auth.Init
is now always called; with disable-authentication it sets up an ephemeral
session store (SESSION_KEY not required) and registers no authenticators,
so the unconditional auth.GetAuthInstance() callers (server init,
api.New()) always get a valid instance.
- main: run the graceful-shutdown sequence on the startup-error path. runServer
derives a cancelable context and, on a server-start failure, cancels it and
waits so the metricstore final checkpoint / WAL rotation, archiver flush and
taskmanager shutdown actually run before exit.
- server: log the :80 HTTP->HTTPS redirect listener error instead of dropping it.
- archiver: guard Shutdown against being called when Start never ran
(avoids close(nil) panic / blocking on a nil workerDone).
- nats API: stop worker goroutines on shutdown via a stop channel + idempotent
Shutdown(); workers and subscription callbacks select on stop and the
channels are never closed, so no send-on-closed-channel can occur. Wired
into Server.Shutdown after the NATS client is closed.
- metricstore: make Shutdown idempotent (nil shutdownFunc, early return) and
release shutdownFuncMu before the checkpoint write.

Addresses the remaining medium findings from the second-pass audit:
- DoS hardening: bound GraphQL query cost with FixedComplexityLimit, and
reject non-positive items-per-page / page values so uint64 conversion
cannot underflow into an unbounded LIMIT/OFFSET. The -1 "load all"
sentinel stays valid for dashboards; REST now returns 400 for bad input.
- Security headers: add X-Content-Type-Options, X-Frame-Options,
Referrer-Policy and a conservative CSP (frame-ancestors/object-src/
base-uri) that hardens against clickjacking and base-tag injection
without restricting the self-hosted SPA's inline scripts.
- Stored XSS: render job.metaData.message as escaped text instead of
{@html ...} in Job.root and JobFootprint, preserving line breaks via
white-space: pre-wrap.
- SQL injection hardening: parameterize the tag-scope IN list and the
manager project subquery in CountTags instead of interpolating
user.Username / user.Projects (externally sourced via OIDC/LDAP).
- CSRF defense-in-depth: reject cross-site state-changing requests via
Sec-Fetch-Site, failing open for non-browser clients, on top of the
existing SameSite=Lax session cookie.

A second-pass audit surfaced three severe issues missed by the previous
review, each a sibling code path of a bug class that was only partially
fixed before:
- auth: JWT session login (jwtSession.go) registered its authenticator
even when CROSS_LOGIN_JWT_HS512_KEY was unset, leaving an empty HMAC
key. golang-jwt verifies any HS256/HS512 signature against an empty
key, allowing unauthenticated admin token forgery. Init() now refuses
to register without a key, with a defense-in-depth empty-key guard in
the keyfunc.
- repository: metric names from GraphQL ([String!]) were interpolated
raw into json_extract(footprint, "$.<name>") SQL. SQLite parses
double-quoted strings as literals, enabling SQL injection by any
authenticated user. Validate metric names against ^[a-zA-Z0-9_]+$ in
jobsMetricStatisticsHistogram and buildFloatJSONCondition.
- metricstore: cluster/host line-protocol tags flowed unvalidated into
path.Join(RootDir, cluster, host) for checkpoint/WAL files, allowing
arbitrary file write outside the checkpoint root via NATS
(unauthenticated) or POST /api/write. Reject path-traversal sequences
in DecodeLine before the tags become path components.
