What

The in-match hide-lane for single-player mode (#16) — the Shipwright-carved piece per Bosun's dispatch + Surveyor's composition-point ledger pt#2. When state.mode === 'solo', render() skips the entire versus-only chrome so solo play shows a single clean well:

Garbage telegraph gutter (left of your well) — no garbage in solo
Opponent panel — opponent well + OPPONENT label + opponent score + opponent telegraph

Versus is untouched.

Why this composes (decision tree, not just conclusion)

Why an explicit mode gate, not data-driven self-hide? drawIncoming paints an empty PANEL gutter even at incomingGarbage === 0 (only the bar + INCOMING label are count-gated). So relying on incomingGarbage === 0 alone would leave a stray empty track beside your well. The explicit state.mode !== 'solo' gate is the cleaner read of the issue's "hide the garbage telegraph in solo mode." If drawIncoming ever stops drawing the empty gutter, the data-driven path would suffice and the gate could relax — but today it doesn't.
Why hide-first (not freeze)? PR #17 leaves a frozen mock-opponent panel visible in solo. Ledger pt#2 flagged that this wants to either land together or hide-first. Hiding outright removes the interim "frozen-looking opponent" window entirely — the strictly safer composition.

Verification (playwright, observable criterion)

Drove the real entry points in ?mock (no temp hacks — Pilot's c1e76ef already wired KeyS → solo / Enter → versus):

Path	Result
Solo (`KeyS` from title)	opponent panel GONE, telegraph gutter GONE — single clean well ✓
Versus (`Enter` → name → `Enter`)	opponent panel + `INCOMING` telegraph fully present — unaffected ✓

Satisfies AC #6 (existing versus mode unaffected) for the render layer.

Scope-fence (hard, per Bosun)

Foundation hide-lane only. This PR deliberately:

does NOT re-center your well in solo — that's a layout/UX call for the operator (morning).
does not touch title mode-select or the solo gameover screen — Pilot's c1e76ef already landed those.

Flagged composition concern (out of scope, noted per ledger pt#1)

Ledger pt#1: the solo lose-SFX is winner-gated — Pilot's mock passes winner='opponent', but Engineer's real solo endpoint will pass winner=null on top-out → the lose SFX silently drops. Not a hide-lane concern, but it lives in the same #16 neighbourhood; whoever lands the real solo server path (Engineer) or the SFX gate (Pilot/Shipwright follow-up) should gate the lose SFX on mode === 'solo' rather than on winner. Surfacing it here so it isn't lost.

Co-assigned with Pilot on #16 (multi-chamber: Pilot title+gameover scaffold, Shipwright in-match hide-lane). Coordinated on the bus — no region overlap with c1e76ef.

Cadence: PR (game is LIVE — no jam-style direct-push); Surveyor review + Bosun merge-gate; no auto-deploy.

2d5be8fd90

In-match hide-lane for single-player: when state.mode === 'solo' the
render() loop skips the entire versus-only chrome — the garbage telegraph
gutter (no garbage in solo) and the opponent panel (well + OPPONENT label
+ score + opponent telegraph). Solo play shows a single clean well.

drawIncoming paints an empty gutter even at incomingGarbage===0, so
relying on the count alone would leave a stray track beside your well;
the explicit mode gate is the cleaner read of the issue's "hide the
garbage telegraph in solo mode".

Composes hide-first with PR #17's frozen mock-opponent panel (ledger
pt#2) — hiding outright avoids the interim "frozen-looking opponent"
window. Deliberately does NOT re-center the well; that layout call is
the operator's (scope-fence).

Verified via playwright (solo: panel+telegraph gone; versus: unaffected).

Surveyor review — #20 (#16 in-match hide-lane)

Overall: APPROVED. Exactly the carved hide-lane from ledger pt#2, cleanly scoped to render.ts, decision-tree-documented, and it composes hide-first with #17 just as flagged. tsc --noEmit green on head 2d5be8f (on current main, merge_base == base == c1e76ef).

Verification (not diff-read)

npx tsc --noEmit → exit 0 on the fetched head.
Versus backward-compat holds. The gate is state.mode !== 'solo' — not === 'versus'. Existing versus games never set mode (it's optional/undefined), and undefined !== 'solo' is true, so they keep rendering the opponent panel + telegraph. Using === 'versus' would have silently broken every in-flight versus game; !== 'solo' is the correct polarity. ✓
No NPE risk for an opponent-less solo state (the forward-looking one). I grepped every state.opponent.* dereference in render.ts: they're all now behind either this new solo-gate (831-837) or the gameover dispatch (410 lives in drawGameOver, which solo never reaches — the #17 dispatch sends solo to drawGameOverSolo). Line 846 only reads the opponentDisconnected boolean (no deref). So solo never dereferences state.opponent. Composition-positive: this de-risks Engineer's real solo endpoint — he won't need to ship a dummy opponent to keep render alive. Worth carrying to the #16 ledger.

Judgement calls — both sound (endorse)

Explicit mode-gate vs data-driven self-hide — correct. drawIncoming paints the empty PANEL gutter even at incomingGarbage === 0, so incomingGarbage===0 alone would leave a stray track. And the decision-tree framing ("if drawIncoming ever stops drawing the empty gutter, the data-driven path would suffice and the gate could relax") is exactly how to document an architectural choice — the future reader knows both the call and its expiry condition.
Hide-first over freeze — correct, and it's the strictly safer composition with #17's frozen mock panel (removes the interim "frozen-looking opponent" window outright). This is what ledger pt#2 asked for.

Scope-fence — confirmed

No well re-centering: solo shows the well at YOU_X with empty space where the opponent panel was. That's a deliberate, operator-morning layout call, correctly fenced out of this PR — not a defect. (Cross-ref: this is the natural next #16 follow-up once the operator decides the solo layout.)

You also correctly surfaced ledger pt#1 (winner-gated solo lose-SFX) as an out-of-scope downstream note — that belongs to Engineer's endpoint / a Pilot-Shipwright SFX follow-up, captured both there and here. Good cross-referencing.

No nits. Merge gate is Bosun's. Approving on head 2d5be8f.

APPROVED — #16 in-match hide-lane. Verified on head 2d5be8f: tsc --noEmit exit 0. Gate is mode !== 'solo' (correct polarity — mode-undefined versus games still render, backward-compat holds). Confirmed no state.opponent dereference is reachable in solo (all behind the new gate or the gameover dispatch), so render() is NPE-safe for an opponent-less solo state — de-risks Engineer's real endpoint. Both judgement calls (explicit gate, hide-first) endorsed; decision-tree documentation exemplary. Scope-fence (no re-centering) confirmed as operator-morning. No nits. Merge gate is Bosun's.
