Raw Blame History

Handoff: Duplicate Chess deployed under chess.sethpc.xyz/duplicate/

Session Metadata

  • Created: 2026-05-19 18:12:12
  • Project: /home/claude/bin/duplicate_chess
  • Branch: main (all work committed + pushed)
  • Session duration: ~30 minutes (after a fresh-session handoff load + a course correction — the user's "deploy the new game mode" originally read like a blind_chess deploy; clarified mid-session to mean duplicate_chess as a 3rd game-mode card on chess.sethpc.xyz).

Recent Commits (for context)

  • cab556e docs: record live deploy under chess.sethpc.xyz/duplicate/
  • a581393 fix: page title (was leftover Vite scaffold 'vite-tmp')
  • 8039a8b build: set vite base to /duplicate/ for sub-path hosting
  • d2adf7f docs: session handoff — duplicate chess v1 built and merged
  • 5047ad7 docs: update CLAUDE.md — v1 implemented and merged

Companion change in the sibling repo: blind_chess @ fef6dcf ("feat(client): third landing card linking to duplicate chess") + 33a7cef (docs note in blind_chess CLAUDE.md).

Handoff Chain

Current State Summary

duplicate_chess v1 is live at https://chess.sethpc.xyz/duplicate/ as of 2026-05-19. It is served as a static sub-app from /var/www/duplicate-chess/ on Caddy CT 600 (192.168.0.185), via a handle_path /duplicate/* block inside the existing chess.sethpc.xyz Caddy site. Vite is built with base: '/duplicate/' so every asset URL carries the /duplicate/ prefix and stays inside the static handler instead of falling through to the blind_chess Fastify backend on CT 690.

In the sibling blind_chess repo, the landing page (Landing.svelte) now shows a 3rd card — "Duplicate Chess (under development)" — beneath the existing friend/AI cards, linking to /duplicate/. That client was rebuilt and rsynced to CT 690; blind-chess.service was restarted to pick up the new bundle.

End-to-end curl evidence:

  • https://chess.sethpc.xyz/duplicate/ → 200, served index.html (title now duplicate chess, no longer vite-tmp).
  • https://chess.sethpc.xyz/duplicate/assets/index-Cu-6IMcr.js → 200, 87103 b.
  • https://chess.sethpc.xyz/duplicate/assets/index-p72E9BrX.css → 200, 4291 b.
  • https://chess.sethpc.xyz/ → 200, blind_chess landing; the JS bundle contains the strings "Duplicate Chess", "under development", "/duplicate/" and the new CSS classes .card-link, .badge, .open-cue.
  • https://chess.sethpc.xyz/api/health{"ok":true,"activeGames":0,"uptime":...}.

Not yet verified by a human in a real browser — Andrew (Seth's dad, the inventor) is the intended remote tester. v1 interactive testing was already pending from the prior handoff.

Codebase Understanding

Architecture Overview

Three independent deploy units share the chess.sethpc.xyz origin:

chess.sethpc.xyz {
    encode gzip zstd
    handle_path /duplicate/* {            # ← new, this session
        root * /var/www/duplicate-chess   # CT 600 (Caddy)
        try_files {path} /index.html
        file_server
    }
    handle {
        reverse_proxy 192.168.0.245:3000  # CT 690 (blind_chess Fastify)
    }
}

handle_path strips the /duplicate prefix before serving, so the on-disk layout under /var/www/duplicate-chess/ is at the root (/index.html, /assets/..., /favicon.svg, /icons.svg). With vite base='/duplicate/', in-bundle asset URLs are /duplicate/assets/... — they re-enter the handle_path, get stripped, and resolve. Symmetric and audit-friendly.

Critical Files

File Purpose Relevance
vite.config.ts Sets base: '/duplicate/' Required for sub-path hosting; default / would 404 on assets
index.html Page title fix — <title>duplicate chess</title> Was vite-tmp from the Vite scaffold
CLAUDE.md Operations + Live URL Resume-time reference
DECISIONS.md Architectural decision recorded (supersedes the "deferred" entry) The "why" for sub-path over subdomain or Fastify static mount
Sibling: blind_chess/packages/client/src/lib/Landing.svelte 3rd card + .card-link/.badge/.open-cue CSS The visible entry point on chess.sethpc.xyz
Caddy: /etc/caddy/Caddyfile (lines ~11121124) on CT 600 handle_path /duplicate/* sub-block Backup at /etc/caddy/Caddyfile.bak.duplicate-chess-1779228542

Key Patterns Discovered

  • Vite base is build-time, not runtime. It is baked into index.html and bundled asset URLs. Switching it requires a rebuild.
  • CT 600 has no rsync. Used tar -cf - . | ssh ... 'cd ... && tar -xf -' to push the dist. Could apt install rsync later for ergonomics.
  • Caddy handle_path vs handle: handle_path strips the matched prefix before downstream directives; handle does not. With base='/duplicate/' in Vite, both forms work, but handle_path lets the on-disk layout live at the root of its own dir — cleaner than mirroring the prefix in the filesystem.

Work Completed

Tasks Finished

  • vite.config.ts set to base: '/duplicate/', rebuilt, committed.
  • index.html title fixed from vite-tmp to duplicate chess, rebuilt.
  • blind_chess Landing.svelte: added 3rd "Duplicate Chess (under development)" card with .card-link, .badge, .open-cue styles. Built, typechecked clean (0 errors / 0 warnings), committed, pushed.
  • Provisioned /var/www/duplicate-chess/ on CT 600; tar-piped both builds.
  • Backed up Caddyfile, added handle_path /duplicate/* sub-block via an idempotent Python text.replace script (failed if the old block was missing or the new block was already present). caddy validateValid configuration. systemctl reload caddy → active.
  • Rsynced blind_chess client dist to /opt/blind-chess/client/dist/ on CT 690, chowned to blindchess:blindchess, restarted the service. The restart dropped 1 in-memory game (per pre-accepted MVP policy).
  • Documentation:
    • ~/bin/CLAUDE.md projects table updated with the live URL.
    • duplicate_chess/CLAUDE.md got the Operations section + new phase line.
    • duplicate_chess/DECISIONS.md "deployment deferred" entry superseded.
    • blind_chess/CLAUDE.md deploy line notes the /duplicate/* Caddy block.

Files Modified

File Changes Rationale
vite.config.ts base: '/duplicate/' + 3-line comment Sub-path hosting
index.html title → duplicate chess Vite scaffold leftover
CLAUDE.md live URL, Operations section Resume-time reference
DECISIONS.md supersede the deferred-deploy decision Architectural record
~/bin/CLAUDE.md projects-table row updated Loaded every session
blind_chess/packages/client/src/lib/Landing.svelte 3rd card + CSS Entry point
blind_chess/CLAUDE.md deploy line mentions /duplicate/* Resume-time reference
/etc/caddy/Caddyfile on CT 600 added handle_path /duplicate/* block Routing

Decisions Made

Decision Options Considered Rationale
Serve duplicate as chess.sethpc.xyz/duplicate/ sub-path (a) separate subdomain like duplicate.sethpc.xyz (b) Fastify static mount on CT 690 Sub-path keeps the user's mental model "one site, three modes"; Caddy file_server is the right tool; isolation from blind_chess server means redeploys don't drop blind games.
Built with Vite base: '/duplicate/' (a) base: '/' with Caddy stripping prefix + serving Building with the right base is simpler and survives any matcher refactor.
3rd landing card as a plain <a href="/duplicate/"> (not a button calling an API) (a) iframe inside the SPA (b) source-merge duplicate's components into blind_chess client Plain anchor is honest about the architecture, no cross-origin/iframe pitfalls; source-merge is excessive for "under development".
Landing card visibly tagged "under development" (a) silent/equivalent Sets expectations for Andrew; signals it's not at parity with blind/vanilla.

Pending Work

Immediate Next Steps

  1. Send Andrew the URL: https://chess.sethpc.xyz/duplicate/ — and the blind_chess landing https://chess.sethpc.xyz/ where he can see both as "modes". Wait for his feedback on the duplicate sandbox UX.
  2. Manual browser test of both the new 3rd landing card AND duplicate's interactive flow (still pending from the prior handoff): play a real game, click a piece, confirm green/grey triple-highlight, move applies to both of the player's boards, etc.
  3. (If Andrew's testing surfaces issues) The known v1 open items in the prior handoff still apply — scrub semantics, provisional endgame rules. Andrew's ruling matters for those.

Blockers/Open Questions

  • Was the right model chosen for "under development" framing? Seth said "incorporate as a 3rd game mode 'under development'." I interpreted that as a 3rd top-level card on the existing two-card landing (since "mode" currently means a radio inside each card, and duplicate is 4-player so can't fit that radio). The card is a plain link out to /duplicate/, not embedded. If Seth wanted an iframe or a deeper integration, redo.
  • All open items from the prior handoff remain open (scrub semantics, the PROVISIONAL endgame rules, the trust-on-player deserialize, …).

Deferred Items

  • apt install rsync on CT 600 — would let future deploys use rsync instead of tar -cf - | ssh tar -xf -. The tar idiom worked but is uglier.
  • Caddyfile cleanupcaddy validate warned about pre-existing Unnecessary header_up X-Forwarded-For/Host in other blocks (not ours) and an unformatted notice. Not introduced this session; safe to ignore.
  • Visual polish on the 3rd landing card — only verified via curl + JS/CSS string grep; not yet eyeballed in a real browser.
  • Open the duplicate sub-app from a deeper path like /duplicate/foo — Caddy's try_files {path} /index.html falls back to index.html for any unmatched path, so any future client-side routing works without changes.

Context for Resuming Agent

Important Context

  • Two repos were touched. duplicate_chess got the vite base + title + docs. blind_chess got the new landing card. Both pushed to main on git.sethpc.xyz/Seth/....
  • Two services were touched at deploy time:
    • Caddy on CT 600 (192.168.0.185) — reloaded after Caddyfile edit (graceful).
    • blind-chess on CT 690 (192.168.0.245) — full restart, dropped 1 in-memory game per pre-accepted MVP policy.
  • chess.local (the LAN-only blind_chess instance on VDJ-RIG) was NOT updated this session. It still serves the previous blind_chess client (no 3rd landing card) and has no /duplicate/ route. The Caddy edit was on CT 600 only. If Seth wants parity on chess.local, redeploy the blind_chess client there and decide whether duplicate is reachable from the LAN at all (no Caddy block currently exists for chess.local/duplicate/*).
  • The phrase "new game mode" caused initial confusion. I (mistakenly) spent the opening few tool calls trying to figure out what new thing in blind_chess should be deployed before asking — none of the recent blind_chess commits described a new mode. Seth clarified the target was duplicate_chess. Future sessions: if a deploy ask seems to mismatch the current repo's state, look at the sibling duplicate_chess repo too.

Assumptions Made

  • That "3rd game mode under development" meant a third top-level landing card, not an in-blind_chess radio addition (duplicate is 4-player — wouldn't fit the existing 2-player radio without a much bigger rework).
  • That a plain anchor link to /duplicate/ was the right shape (vs iframe).
  • That dropping the 1 active in-memory blind_chess game on restart was OK (matches the pre-accepted MVP policy in DECISIONS.md).

Potential Gotchas

  • vite-tmp was the page title at first deploy (a581393 fixed it, but there was a ~2-minute window where it shipped). If Andrew tests during a redeploy window, mention it.
  • Caddy handle_path strips the prefix — anyone reading /var/www/duplicate-chess/ layout might expect a duplicate/ subdir; there isn't one (files live at the root of that dir).
  • Files in /var/www/duplicate-chess/ are owned by uid/gid 1001 (the claude uid on steel141, passed through via tar), readable to all. Worked because Caddy needs only read; chown to caddy:caddy or root:root would be tidier.
  • localhost on VDJ-RIG (where chess.local lives) hits a Caddy 502 — documented in the prior handoff. Doesn't affect this deploy (we touched CT 600's Caddy, not the rig's).
