Summary

Phase 0, PR 0.1 of the reputation portability plan (mostro/docs/REPUTATION_PORTABILITY.md, §6.1 and §9).

days is derived at publish time, so it is stale on any event that lives on relays for a while, and it cannot be merged sensibly when reputation is imported from another venue. The underlying datum is a date, so the public field becomes one.

  • since — Unix timestamp of the user's first trade, truncated to the start of its UTC day (created_at - created_at % 86400). Clients compute the age at display time. Added to the rating tag on kind 38383 and as a tag on kind 38384.
  • days — marked DEPRECATED at both sites. Mostro publishes both for one deprecation window and removes days in the minor release after the one that first publishes since. Clients MUST prefer since when present and MAY fall back to days while the window lasts.
  • The rating tag's JSON object is now described field by field on the order event page; before, the page only said the platform defines it.
  • Every example carrying a rating (order_event, user_rating, list_orders, the four new_*_order* pages) shows since next to days, computed from that example's own created_at.

Why day precision: the rating tag travels on every order of the same user, and a second-precision value would make their trade pubkeys trivially correlatable. A day carries exactly the information days carried today.

Out of scope, by design

  • UserInfo.operating_days on the peer payload is a mostro-core type the protocol book does not document field by field today; its since counterpart lands with core PR 1.1.
  • The band grid (0.2), keyset event (0.3), actions (0.4) and vectors (0.5) follow as their own PRs.

Checks

  • mdbook build succeeds locally
  • Every since in the examples equals day_truncate(created_at - days * 86400) for that example

Summary by CodeRabbit

  • Documentation
    • Updated order and rating event examples to include a since Unix timestamp in rating data.
    • Clarified that since represents the user’s first trade, truncated to the start of the UTC day.
    • Documented the transition away from the stale days field, including client fallback guidance and the temporary period where both fields are published.

… deprecate `days`

`days` is derived at publish time, so it is stale on any event that lives on
relays for a while, and it is awkward to merge. The underlying datum is a
date, so the public field becomes one: `since`, the Unix timestamp of the
user's first trade truncated to the start of its UTC day.

Day precision is deliberate. The rating tag travels on every order of the
same user, and a second-precision value would make their trade pubkeys
trivially correlatable; day precision carries exactly what `days` carried.

`days` is marked DEPRECATED at both sites (the `rating` tag on kind 38383
and the `days` tag on kind 38384). Mostro publishes both for one deprecation
window, then removes `days` in the minor release after the one that first
publishes `since`. Clients MUST prefer `since` and MAY fall back to `days`
while the window lasts.

Every example carrying a rating now shows `since` next to `days`, computed
from the example's own `created_at`.

Reputation portability plan, phase 0, PR 0.1 (mostro
docs/REPUTATION_PORTABILITY.md §6.1 and §9).

The documentation adds a since timestamp to rating examples, defines its UTC-day semantics, and marks days as deprecated with client fallback guidance.

P2 Badge Compute since from the order publication timestamp

For these published kind 38383 events, days is the user's age at the enclosing event's created_at (1702548701), so 10 days corresponds to since: 1701648000. The current value is instead derived from the unrelated kind 14 request timestamp (1234567890), making the two fields disagree by roughly 14 years; the same error appears in new_buy_order_ln_address.md and new_sell_order.md, while new_sell_range_order.md similarly derives it from the older confirmation payload. Clients comparing the legacy and replacement fields during the documented transition will therefore learn the wrong conversion.

Use the rating object as the serialized rating value.

src/order_event.md defines and serializes rating as a JSON object. Remove the extra ["rating", ...] array from both src/list_orders.md:23 and src/new_sell_range_order.md:94.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Keep since and days consistent in all rating examples.

The deprecation window requires both fields. Set since to the UTC-day-truncated first-trade timestamp that corresponds to days:10. Apply this correction in all three examples.

Keep the serialized rating shape consistent.

This example encodes the rating value as a JSON array containing "rating" and the object. src/order_event.md:43 documents a JSON object instead. Align this example with the contract and with src/list_orders.md.

Set since to 1701648000. The event date is 2023-12-14 UTC, but 1697932800 is 2023-10-22 UTC, which makes the rating age 53 days instead of days:10. Use the UTC-day-truncated timestamp for 2023-12-04 so both fields agree.
