Known limits

Every ceiling here shares one rule: when it applies, it is stated. Nothing is silently truncated, and no list shows a subset while looking complete.

Tables

Limit	Behavior
A table never scrolls sideways	The width is shared out between the columns, each is held above a legible floor, and whatever still does not fit moves into a per-row panel opened by "Show N more fields"
One line per cell	The full value is in the tooltip and in the row drawer
Rows per page	10 / 20 / 50 / 100, stored per table and per browser
Event history	The most recent events are shown; a note states how many out of how many, and says to narrow it with the filters
A preview list on a record's Summary tab	Five rows. Beneath them a line states how many more there are and where the full list is — on its own tab
A bulk action on 20 rows or more	Asks for confirmation, naming the row count
A link from a table into the scheduling wizard	Up to 50 items. What was dropped is stated, and the rows past the ceiling are drawn dashed rather than removed

Row density is the reader's own choice and is stored per table.

Saved views

A saved view holds the display strings of its filters, not codes. So:

• it survives a column being hidden or removed — an unknown key is simply skipped;
• it does not survive a Hebrew label being reworded. After such a change the view loads without an error and matches nothing.

That is the reason to reword labels deliberately and to check the saved views afterwards.

Graphs

Limit	Behavior
How many nodes are drawn	A "Show" control with explicit steps and an "All" option — 30/60/120 on the estate map, 50/150/300 on the system graph, 20/40/80 on the neighbor view. Never a silent ceiling
A large neighbor view	Above roughly 20 neighbors it opens as a matrix rather than a graph; below that, radial. It can be switched by hand
Keyboard and screen readers	The canvas itself is not keyboard-navigable. Every graph has a Table tab carrying exactly the same state, and the graph's description points at it explicitly
Saving an image	"Save image" writes a PNG only, at twice the screen scale, of the current view. There is no vector export
Zoom and position	Preserved when you change color, size or focus. An action that moves nodes — a layout change, or a change to the set of nodes — rebuilds the view. "Reset the view" returns it to fit

Reports and formats

• The format list is decided at runtime from what is installed on the server. A format that cannot be produced is not offered, and the reason is printed beside it.
• HTML is always available and is the only format that appears in the mail body. Everything else is attached as a file.
• Both delivery logs show the most recent 200 entries, filterable by report or by rule.

Messages

An SMS that is not English-only is sent in UCS-2: 70 characters in one segment, 67 in every further segment. The meter under the text box shows the segments, how many characters are left in the segment, and the cost line — segments × recipients = billed messages. One added Hebrew character can add a segment for every recipient.

Deployment

One application process. The system is not designed to run as several concurrent copies: the internal schedulers live inside the process, and two copies mean two reminders and two reports. The full explanation is in Architecture.
