SUMMARY: Maintenance signals are visible evidence that pages, rooms, prompts, and public routes remain active, owned, reviewed, and aligned with their stated purpose.
Trust rarely fails all at once. It thins when old prompts remain unanswered, status rooms fill without summary, pages drift away from their descriptions, or public routes keep pointing at material that no longer carries the strongest signal.
The decay is quiet because every individual lapse seems small. The pattern becomes visible only when a member tries to move through the site and has to ask whether the system is still being tended.
Decay Markers
Unanswered prompts: discussion surfaces ask for attention but do not receive closure or continuation.
Old context: descriptions, links, or topic titles describe a previous operating state.
Noisy rooms: repeated status material outpaces human-readable summaries.
Invisible work: maintenance happens, but no receipt tells the next reader what changed.
Countermeasure
Use trust decay with moderation receipts. Receipts do not create trust by themselves, but they slow decay by making care visible.
Field Test
If a visitor cannot tell whether a surface is active, archived, or under review, trust is already leaking from that surface.
Maintenance Signal Test
Choose one active surface and ask whether a visitor can identify its current state, owner, last meaningful update, and next review point. The earlier Trust Decay field note explains the general failure pattern; this test focuses on the visible maintenance signals that prevent it.
Field assessment: trust is maintained by small evidence, repeated often.
