multiplayer-next.md was a 1662-line mix of standing architecture spec
and task-completion tracking, most of which was dense per-task DONE
evidence for finished Phases 0-6. Split it:
- MULTIPLAYER_SPEC.md (new): the locked architecture decisions, wire
format, server-side input handling, prediction/reconciliation,
latency/frame-rate budget, and match lifecycle state machine -
standing design reference, not task-tracked.
- multiplayer-next.md (trimmed 1662 -> ~370 lines): only outstanding
work remains - §0 status, §7 Phase 7/8 task tables condensed to
"what's left" per task, §8-11 reference material (refactoring notes,
gotchas, testing, flagged items). Phases 0-6 collapsed to a pointer
at git history instead of ~500 lines of DONE evidence.
Also:
- Repointed every `multiplayer-next.md §N` code comment (N 1-6) across
Game/scripts, Game/tools and Game/tests to MULTIPLAYER_SPEC.md, since
those sections moved. Task-number references (`task N.N`, §7-11)
correctly still point at multiplayer-next.md.
- Updated CLAUDE.md's doc index and docs/TECH_STACK.md's spec-section
citations to match.
- TODO.md: added a "what's left to actually finish multiplayer
(human-actionable)" checklist pulled from multiplayer-next.md §0 and
docs/MATCHMAKING.md - things that need a person (hardware, a design
decision, a Steam App ID, hands on a controller), not more agent code.
Add a Go-vs-C#/Rust/C++ rationale for the matchmaking control plane to
TECH_STACK.md, and point at it from MATCHMAKING.md and README.md.
Also correct CLAUDE.md and README.md, which still described the backend
as unstarted/not built even though server/ has ~13k lines of Go across
matcher, allocator, api, store, security, supervisor and agones.
multiplayer-todo.md and multiplayer-next.md tracked overlapping
information in two places. Fold everything into multiplayer-next.md
(architecture decisions, wire format, task breakdown with checkboxes,
gotchas list, testing notes) and delete multiplayer-todo.md. Section
numbers are unchanged, so existing code comments citing them by
section/task number still resolve; update every such reference to
point at the new filename.
Queued matchmaking had never been considered anywhere in the planning
docs - not as planned work, and not even on the explicitly-deferred
list. It is a launch requirement, so record the design before code.
Add docs/MATCHMAKING.md covering the model change (community-server ->
per-match allocation), the decision to use Steam for identity and a
project-owned backend for queue/rating/allocation, what the existing
server already provides (--max-matches=1 is the allocation primitive,
ServerConfig, the roster, MatchState), the casual/ranked ruleset split,
and the open questions - rating algorithm, team-to-individual rating,
and the server cost that allocated matches reintroduce.
Ranked is hard-blocked on Phase 7 Steam auth tickets: slot reclaim is
keyed by display name today, and a rating on a spoofable identity is
worse than no rating.
Add Phase 8 to multiplayer-next.md, and correct README/CLAUDE.md/
TECH_STACK.md, which asserted no backend exists or is planned - true
before this was scoped, wrong now.
CLAUDE.md and README.md described the pre-multiplayer state (local-only
MVP, planned C# backend) even though server-authoritative multiplayer,
the dedicated server, Docker/CI verification, and Steam transport have
since shipped (Phases 1-6). Update both to reflect reality and add a
docs index in CLAUDE.md pointing at multiplayer-next.md as the current
checklist.
- Add docs/TECH_STACK.md, linked from README, explaining the stack and
why it's a single GDScript project with no separate backend.
- Add one TODO item for the video settings menu (missing presets/vsync/
resolution scaling), blocked on the same profiling gate as the
multiplayer 0.17 tasks.
- Pick up editor-generated .gd.uid sidecars and minor project.godot
formatting noise from opening the project in Godot 4.7.
