v1.1.4

- Configurable ticket numbering (Admin > Konfiguracja > Ogólne): admin-set
  prefix and minimum zero-padded length for the ticket number.
- "Ukryj kolejność zgłoszeń": an opt-in mode that displays a stable,
  HMAC-derived checksum instead of the sequential ticket number, so it gives
  no indication of ticket volume or creation order. Ticket URLs switch to
  the same checksum when this is on, so a link and the number on the page it
  points to always match. The REST API is unaffected — pinned to `id`
  regardless of this setting. Search now also matches by checksum.
- Fixed: attachments no longer show an inline image thumbnail in the
  message thread — every attachment (images included) shows as just its
  filename, opening in a new tab on click.
- Docs: README/ARCHITECTURE/wiki updated for all of the above.

+## Ticket numbering & URLs
+
+A ticket carries three distinct identifiers, each with a different job:
+
+- **`id`** — the DB primary key. Never shown to users; the REST API
+  (`routes/api.php`) is deliberately pinned to it (`{ticket:id}` explicit
+  binding on every `{ticket}` route) so external integrations have a stable
+  contract regardless of the numbering settings below.
+- **`number`** — a plain sequential string (`Ticket::nextNumber()`, max+1
+  starting at 1001), unique but otherwise unremarkable. Backs `scopeSearch()`
+  and the numeric sort in `Operator/Queue.php` regardless of display mode.
+- **`checksum`** — a 6-digit HMAC-derived value (salted with `app.key`,
+  keyed off `id`), assigned once in a `Ticket::booted()` `created` listener
+  and never changed afterward. Collisions are handled for real, not just
+  assumed away: `Ticket::generateUniqueChecksum()` walks a nonce forward
+  until the candidate is free (checked against the DB), and the column has a
+  `unique()` constraint as a hard backstop.
+
+`Ticket::displayNumber()`/`formattedNumber()` pick between `number` (zero-padded
+to `Settings::get('ticket_number_min_length')`) and `checksum` based on
+`Settings::bool('ticket_number_obfuscate')` — the "Ukryj kolejność zgłoszeń"
+toggle in Admin > Konfiguracja. `Ticket` also overrides `getRouteKey()` and
+`resolveRouteBinding()` to mirror that same choice, so **the web routes**
+(`routes/web.php`, all plain `{ticket}` implicit bindings — no explicit field)
+resolve and generate URLs against whichever column is currently the display
+number: flip the setting and both the visible number *and* every link
+(`route('client.ticket', $ticket)` etc.) switch together, and a bookmarked URL
+built under the old mode stops resolving. This is why the API routes need the
+explicit `{ticket:id}` override — without it, the same global `getRouteKey()`
+change would silently start requiring `number`/`checksum` in API path params
+too, breaking the documented `integer` "Ticket id" contract.
+
+The `{numer}` placeholder available in admin-editable e-mail templates
+(Admin > Szablony e-mail / Wyzwalacze) resolves to `formattedNumber()`
+*without* `displayNumber()`'s prefix — those templates already hardcode their
+own `#{numer}`, so adding the prefix there too would double it up or clash
+with a non-default prefix.

 All notable changes to this project are documented in this file. Format loosely
 follows [Keep a Changelog](https://keepachangelog.com/en/1.1.0/).
 
+## [1.1.4] - 2026-07-23
+
+### Added
+
+- **Configurable ticket numbering** (Admin > Konfiguracja > Ogólne) — an
+  admin-set prefix (default `#`) and a minimum zero-padded length for the
+  ticket number.
+- **"Ukryj kolejność zgłoszeń"** — an opt-in mode that displays a stable,
+  HMAC-derived checksum instead of the sequential ticket number, so the
+  number shown gives no indication of ticket volume or creation order. Every
+  ticket gets its checksum assigned once, on creation, guaranteed unique.
+  When this mode is on, ticket URLs switch to the same checksum too (custom
+  `Ticket::getRouteKey()`/`resolveRouteBinding()`), so a link and the number
+  on the page it points to always match — and a URL built under the other
+  mode stops resolving. The REST API is unaffected; it's pinned to `id`
+  regardless of this setting. Search (queue/dashboard) now also matches
+  against the checksum. A live preview against a real ticket from the
+  database shows exactly how the number will look before saving.
+
+### Changed
+
+- **Attachments**: dropped the inline image thumbnail preview in the message
+  thread — every attachment (images included) now shows as just its
+  filename, opening in a new tab on click, consistent with how non-image
+  attachments already worked.
