   distinguished from a real failure, or a disconnected browser inflates the

+- `login` — the one decoder of meta.sr.ht's unified-login cookie. Six services
+  read the same fernet-sealed cookie and each made the same five decisions
+  alone: decrypt without an expiry (a service-side TTL logs a viewer out of
+  that one service on a schedule no sibling shares), take the name, strip the
+  `~`, treat every failure as anonymity rather than as an error, and validate
+  the name before it reaches a path, a log line or a query. `Optional` never
+  refuses and `Required(deny)` does, because folding the gate into the decoder
+  is exactly how the six copies drifted. The validator cannot be switched off:
+  the two services that validate nothing today are the two that would go on
+  passing nothing.
+- `internalauth` — both ends of the `Authorization: Internal` handshake
+  between services, which core-go implements unexported. Minting and verifying
+  live in one package on purpose: dolt had the receiver in one repository and
+  the caller in another, so a change to the payload broke provisioning at
+  runtime instead of at compile time.
+- `instconf` — canonical reading of the shared config's origins. Five services
+  and this library disagreed about what "the origin" is: `TrimRight` against
+  `TrimSuffix`, a malformed one becoming `""` here and `"localhost"` there —
+  on a path that includes a DNS-rebinding guard, where an empty host means the
+  guard is off. `OriginHost` (no port) and `OriginAuthority` (with it) are two
+  concepts, not a drift.
+- `logging` — the instance's slog policy without the handler: level from
+  `-d`/`$LOG_LEVEL`/config, colour from `NO_COLOR` and the terminal, and the
+  credential mask set. The mask set is the shared part — what is being redacted
+  is the instance's login cookie and its bearer tokens — while tint-versus-JSON
+  is the service's own call, so the policy also ships as a stdlib
+  `ReplaceAttr`. `middleware.RecoverPanics` reports through `slog.Default()`,
+  which is what gave ecore a stake in every service installing a compatible
+  handler.
+- `chimw` — the chi-shaped helpers, kept out of `middleware` so that package
+  can stay dependency-free: `GetHead`, the 404/405 installer pointing at the
+  service's own error page, and a request logger that emits a slog record
+  instead of chi's unstructured line on stdout.
