Drops the 4-letter alias convention in favour of a single homogeneous
naming axis: full English words across filesystem, alias, wire format
and constants.
Module renames:
- arts/aapp → arts/active-app (libs/aapp also)
- arts/buss → arts/bus (libs/buss also)
- arts/cach → arts/cache (libs/cach + svrs/cach also)
- arts/conn → arts/connection
- arts/fend → arts/frontend
- arts/fmts → arts/formats (curr→currency, nums→numbers, unts→units)
- arts/logr → arts/logger (libs/logr also)
- arts/perm → arts/permissions (libs/perm + svrs/perm also)
- arts/sess → arts/session
- arts/stor → arts/storage
- arts/timr → arts/timer (libs/timers → libs/timer)
Modules left as-is: auth, dom, errs, http, lang, sium (already match
their canonical name or are proper names).
Special case: `aapp` could not become `app` because `$app` is reserved
by SvelteKit (`$app/stores`, `$app/navigation`, ...). Compromise:
- Filesystem and alias use `active-app` / `$active-app`.
- Constants and class names use `App` / `APP_*` (no `active-` prefix).
The `active-` prefix only disambiguates the alias from SvelteKit's
namespace; the module is App.
Special case: `permissions` keeps the plural for filesystem/alias/wire
but constants and classes use the singular `PERMISSION_*` /
`Permission*` because they describe the concept ("a permission
effect"), not the module collection.
Constants follow the new module name in caps: `STORAGE_*`, `BUS_*`,
`CACHE_*`, `CONNECTION_*`, `FORMATS_*`, `LOGGER_*`, `SESSION_*`,
`TIMER_*`, etc. Module values: `STORAGE_MODULE = 'storage'`,
`BUS_MODULE = 'bus'`, `APP_MODULE = 'app'`,
`PERMISSION_MODULE = 'permissions'`, etc.
Wire/code format moved accordingly: `'storage::*'`, `'bus::*'`,
`'session::*'`, `'permissions::*'`, etc. Diagnostic event values
updated: `'storage.error'`, `'bus.event.published'`,
`'connection.auth_failed'`, etc. App events use `'app.*'`:
`AAPP_EVENT_* → APP_EVENT_*` with values `'app.user.identity.changed'`.
Class renames (where they used the abbreviation):
- AappAlreadyCreatedError → AppAlreadyCreatedError
- BussError* → BusError* (where applicable)
- Cach* → Cache*
- Conn* → Connection* (e.g. ConnDisposedError → ConnectionDisposedError;
ConnConnection* collapsed to Connection*)
- Logr*Error → Logger*Error
- Sess* → Session* (SessInvalidSessionError → SessionInvalidError)
- Stor* → Storage*
- Timr* → Timer* (TimrInactiveTimerError → TimerInactiveError)
- AuthCachPort → AuthCachePort
- AuthClientCach* → AuthClientCache*
- AuthPermPort → AuthPermissionsPort
Property renames in option types:
- `cach?:` → `cache?:` in AuthClient options
- `logr:` → `logger:` in svrs/auth ports
- `timr:` → `timer:` in svrs/auth ports
`docs/conventions.md` rewritten:
- Rule 1 dropped the 4-letter alias mandate; lists the full English
module names and special-cases active-app, lang, sium, permissions.
- Rule 2 documents the new constant prefix convention and its two
exceptions (APP_* for active-app, PERMISSION_* singular for
permissions).
- Rule 6 codifies that all error infrastructure (codes, messages,
classes, guards) lives in a single `errors.ts` per module —
removing the `consts.ts` / `errors.ts` split for error-related
symbols.
`libs/errs` adds `ErrorMessages` type so every module can declare its
catalog as `<MOD>_ERROR_MESSAGES: ErrorMessages` instead of repeating
the `Readonly<Record<ErrCode, string | (...args) => string>>` shape.
Storage migrated as the first proof of the canonical pattern.
All 1334 tests pass.
