Follows #137. The v0.24.1 fix made the count honest and stopped a thousand round trips per poll, but it assumed the unique index on (device_id, log_id) would reject lines already stored. For most devices it does. For a device whose log entries carry no `.id` it never could: the column was set to NULL, and PostgreSQL treats NULLs as *distinct* in a unique index, so every NULL conflicts with nothing. Those devices re-inserted their entire buffer on every poll, for ever, and the constraint that was supposed to stop it was structurally incapable of firing. A line with no id now gets a key derived from its own content -- timestamp, topics and message -- so the existing index does the work. The `#` prefix keeps it out of the space of real RouterOS ids (`*` plus hex), so the two cannot collide, and parseRosId already rejects it, which matters because the watermark is a max over real ids and must not be poisoned by a synthetic one. The trade, stated rather than buried: two genuinely separate lines sharing a timestamp, topic and message collapse into one. RouterOS timestamps are second-resolution, so that can happen. Losing a repeat of an identical message is a much smaller loss than growing the table by the whole buffer every minute without bound. This was found by reading a comment on #137 I had not read before closing it -- log output from a device with eleven lines total, reporting eleven new entries every minute for forty-five minutes. My own fleet cannot reproduce it: every event here carries a real `.id`, with no nulls and no duplicates, which is exactly why the hole was invisible from here. So this closes a defect demonstrable from the schema; whether it is the whole of that reporter's problem is still an open question and the issue is reopened to ask. Verified no regression where ids are healthy: no surrogate keys generated, no nulls, no duplicates, and counts that vary with real activity. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
