DanConwayDev aa543d8051 feat(relay): make discoverable hardening limits explicit
Motivation: rust-nostr 0.45 introduced a broad local-relay hardening series
whose effective defaults were mostly absent from its changelog and entirely
absent from ngit-grasp's custom NIP-11 response. One new 64 KiB event bound is
incompatible with production history containing a valid roughly 149 KiB
NIP-34 patch event. Leaving other defaults implicit risks another dependency
upgrade silently changing serving policy, while exposing every internal knob
would create configuration that peers cannot usefully negotiate.

Approach: explicitly select every retained rust-nostr hardening value in the
builder. Expose only the subscription and per-filter result limits that peers
can discover and ngit-grasp sync already consumes, plus the Git-specific event
size policy. Apply one filter-limit option consistently to explicit, query,
and omitted-limit caps. Raise the event default from 64 KiB to 192 KiB and
validate it remains beneath the fixed 5 MiB WebSocket message ceiling. Publish
the standard NIP-11 limitation fields and correct the architecture/reference
documentation, including removal of the obsolete max_filters claim.

Correctness: the NIP-11 max_subscriptions value feeds the existing per-session
subscription ledger; default_limit feeds adaptive pagination with its existing
verification-page safeguard. max_limit is advertised truthfully but is not
misused as an omitted-filter promise. The 192 KiB bound clears the observed
patch by about 29% while preserving a finite allocation boundary. All three
new options are synchronized across source, reference docs, NixOS, and the
environment example.

Excluded scope: message-size negotiation, filter-payload limits, per-IP
fairness, and non-standard NIP-11 extensions remain separate work. Rate,
handshake, subscription-memory, filter-count, and negentropy bounds are pinned
but deliberately not operator-configurable because our sync cannot negotiate
them through standard NIP-11 fields.

Validation: focused unit tests passed for explicit configuration defaults,
event/WebSocket size validation, configured NIP-11 advertisement, and the full
http::nip11::tests module (10 tests before adding the focused override case).
The previously validated full library suite and deployment build were not
repeated at the user's request.

Reference

Information-oriented documentation - Technical details and specifications.


What Is Reference Documentation?

Reference documentation provides factual, technical information that you look up when needed.

Characteristics:

  • ✅ Information-oriented (facts and data)
  • ✅ Comprehensive and accurate
  • ✅ Structured for lookup
  • ✅ Dry and to-the-point
  • ✅ Maintained as code changes

Not reference:

  • ❌ Learning materials (those are Tutorials)
  • ❌ Problem-solving guides (those are How-To)
  • ❌ Conceptual explanations (those are Explanation)

How to Use Reference Documentation

  1. Know what you're looking for - Reference is for lookup, not learning
  2. Use search or table of contents - Find the specific detail you need
  3. Check version - Ensure docs match your version
  4. Verify with code - Reference should match implementation
