Implemented the display updates, rebuilt dist/, and updated documentation. Contract, RPC and wallet flow remain unchanged.

Build, typecheck, 16 model tests and 7 DOM checks passed. Browser startup failed with crashpad/SIGTRAP errors, so 375px visual checks remain unverified; details are in VALIDATION.md.

The update meets every requirement in the brief. I found one low-severity defect: two count labels on the War page always use the plural. It's written up in .imd-findings.json, and no project files were changed.

How I checked: I served dist/ in Chromium at 375 px with live Sepolia reads from the contract the brief names. The rankings, war, my guild, create, rules, recruiting and trophies pages all load. Every page I measured fits the 375 px width (the page measured 375 px wide), and the site made no requests other than to the public RPC. Sepolia has exactly one guild, #1 "Golden Squeek", so I tested the one-guild case on live data. I tested the zero-guild case only by what the pages show when they can't read the chain: each shows a "could not be loaded" message with a Refresh button and no made-up data. I did not check Safari (WebKit).

Requirements

1. Guild ID next to every name – met. One shared helper adds "#id" (model.ts guildLabel), used in Rankings, My guild, War, Recruiting, Trophies, Profile and the share card (art.tsx shareCard).
2. Duplicate-name warning on Create, not blocking – met. Typing " golden SQUEEK " shows "A guild named like this already exists (#1). Players will tell yours apart by its ID." It also appears in the confirmation text before signing, and creation is still allowed (CreateJoin.tsx).
3. Members column always visible (now / seats) – met. Live it shows "1 / 10" at 375 px.
4. "small sample" label under 5 members – met. It shows under the score for guild #1.
5. "Only guilds with 5+ members" toggle – met. It's off by default, sits next to the tier filter, and the existing sort options are unchanged.
6. Sentence under the table – met, with the exact wording.
7. Member count beside each score on the War page – met. It shows on the form ("· N season members") and on the scoreboard.
8. Note when the crews differ by 3 or more – met (War.tsx:278).
9. Notice under "Submit a war" – met, with the exact wording.
10. Plain explanation before a kick – met. It's in the kick confirmation and in a line above the crew list that only captains see.
11. "Recent changes" on My guild – met. It lists Kicked events with the wallet and block time, and says "No member removals recorded for this guild." when there are none.
12. "Roster changed this season: N…" line in the comparison – met. It counts Left and Kicked events from that season (model.ts seasonDepartures).
13. Rules page "Known limits" – met. All four points are there, and "Unofficial community project; no tokens, no payouts." is still shown.
14. Same contract, chain and RPC – met. Contract 0x4d9c…1d30, Sepolia, read through publicnode only.
15. Kept as before – met: dark theme, hamsters, tug of war, empty states, the simulation before each transaction, the 30-second refresh and the reduced-motion handling. Nothing new was added (no token, tips or analytics).
16. No overflow at 375; Rankings, War and Create load – met with one guild (see above).

Finding

• Low, bug: "1 season members" (web/src/War.tsx:227, and lines 255 and ~378). Under the first guild picker the page reads "20 points / member · 1 season members". The roster line uses the same fixed plural, so one departure would read "1 members left or were removed". The fix is to pick "member" or "members" from the count.

Probe failures I didn't report: the all-caps tracked labels, the "Current season" label read as a kicker, and IBM Plex Mono used for
