Hold The Horde — Campaign Evidence and State Crosswalk

Status. A finite crosswalk over content that already exists: it maps the eight accepted chains and fifteen primary cast scenes onto the actual rooms, controls, objects and observations they consume, and records where those interfaces agree or conflict. It is not a campaign map, a scheduler, new content, story truth, language grammar or a validation of anything. No new chain, person, room, mechanism, scene or object is created here. All five owner questions remain unanswered, and only their actual consumers are marked conditional.

The last four cast/room/encounter/save versions are the 514-aligned ones accepted at 518. Mechanical Interfaces and Opening Quantities is under review and is not used; cells that genuinely depend on it are marked (35-dependent) and left provisional rather than filled with invented quantities.

Counts. 8 chains (L1–L4, S1–S4) · 15 primary scenes (Y1–Y3, A1–A3, D1–D3, M1–M3, I1–I3) · 19 deduplicated evidence entries · 7 mutually exclusive rescue host variants · 5 Story30 personal variants · 2 progression orders. Existing inventories are unchanged: 24 modules / 40 rooms, 10 encounters including 2 setpieces, 13 major mechanisms.

1. Chain and scene identity map

Canonical IDs are reused. L1–L4 are Two Language Discovery Map's four chains; S1–S4 are Story and Ending Map's four mystery/personal chains; Y1–I3 are Cast and Short Rescue Map's fifteen scenes. Where an observation has no ID anywhere, this article names a local crosswalk key (X-…) and proposes an owner; a key is a handle for something that already exists, never a new object.

Host variants (7), stated so no cell reads as a free reuse. R13 hosts Y1 or A1, never both; the loser takes R19 pressure annex (Yeva) or R22 supply booth (Aster). Abort hosts are the four already counted rooms — R06, R12, R24, R27 — and no scene adds a fifth.

2. Deduplicated evidence and knowledge ledger

One entry per observation. A shared observation is listed once with its separate linguistic and narrative consumers.

One observation, two kinds of consumer. E-TRANSFER feeds L3 as a linguistic role distinction and S3 as evidence about a movement; E-REPLY feeds L4 as register evidence and S2/S4 as evidence about what the line is; X-PROFILE feeds S2 as causal evidence and Y3/M3 as something a person reacts to. Each is captured once and consumed several times — no duplicate capture is implied anywhere.

3. Representative state and commit boundaries

Three separations this crosswalk insists on. Retaining an inference is not informing a survivor — a player may hold a correct reading for hours while every person aboard still knows nothing, and no scene fires on the inference alone. A control responding is not proof of identity or history — E-REPLY shows that something answers, never who or what. Physical network completion is not an ending theory — joining every room is a walkable fact under objective 12; what the core contains is S4, and neither settles the other. The full transaction, storage and display rules are not restated here; see the accepted continuity, Save and Content State, and Player Information and Options.

4. Two traces and four contrary cases

Trace A — Yeva-first. Objective 1 gives the R-3 bearing. E-INSTALLED records the Fork at R02 the moment it is installed, and the first death makes the route to it historical while the fact stays current — this is S1's opening evidence before any story reading exists. A later short current geometry at objective 4 enables Y1 at R13: the player captures X-WALLLOG in exposed world time or crosses immediately. After Sent, Y2 shows the bench setup incomplete, because Dorn has not serviced the inherited head — a state, not a refusal. Objectives 5 and 7 proceed with no survivor testimony at all: E-RUNS, E-TAAN, E-AB and E-TRANSFER are player-only. Yeva's road names remain attributed help, never translation. D1 later needs its own walked side route; D2 completes the receiver, and only then can a demonstrated cycle exist. Aster enters when objective 7's booth has a verified short route, bringing X-LEDGER for A2.

Trace B — Aster-first. A1 occupies R13 and A2 gives a first-return comparison with no other project visible. After an ordinary death, A3 puts X-BERTH beside X-MANIFEST: with both she retracts "every arrival" and keeps "this docking may"; with one she keeps the wider theory. Yeva later occupies the objective-6 pressure annex — never R13 — so Y1's host moves while its evidence and choice do not. Every physical language path is identical in both orders, because L1–L4 consume no testimony.

Contrary case 1 — retained evidence, changed access. The player holds E-WALLMARK from R17 and dies. The record keeps its place and life; the route to R17 is historical. The mark's meaning is unaffected, but whether that wall is passable now is a current-only fact requiring a fresh visit. Nothing in the ledger promises the room is reachable this generation.

Contrary case 2 — wrong interpretation, concrete correction. From two E-TRANSFER pairs the player reads the recurring token as source and predicts a continuation. The corrective third pair at R23 shows the same token at a receiving end. The correction is physical and self-administered: no interface says "wrong", the earlier note keeps its original wording in revision history, and L3's decision — which continuation to investigate — changes on the player's own reading.

Contrary case 3 — absent versus uninformed participant. X-PROFILE is committed. If Dorn was never rescued, Y3 has no Dorn variant and nothing is lost invisibly. If Dorn is aboard but was never shown the comparison, he is present and uninformed — a different state, and the scene must not let his knowledge update by proximity. The crosswalk treats these as two distinct rows, because collapsing them would make sharing meaningless.

Contrary case 4 — apparent versus deeper ending, with the departure branch open. Objective 10's assemblies can make departure readiness true with no language, survivor or core answer — an apparent ending path. The deeper transaction at R40 is separate and does not require it. The departure branch is unresolved and stays that way here: the in-world irreversibility (leaving the field ends revival and closes station exploration in this continuity) is distinct from the unanswered save policy, and this article selects neither. Completing objective 12 is a physical fact that neither triggers nor blocks either.

5. Integration handoff

Where a link is enough: every cross-article reference above except the two tagging cases. Nothing in this crosswalk requires a parent edit to be correct, because it changes no rule — it records what the existing articles already say and where they disagree.

Coverage and limits

Complete for what was assigned: all 8 chains and all 15 primary scenes are mapped, both progression orders are traced, and the evidence ledger is deduplicated across them. Not covered, and not claimed: the full occurrence/branch/failure variants of each chain, exhaustive permutations of order and participation, any glyph or string catalogue, and the exact behaviour of anything owned by Mechanical35. Ten encounters, two setpieces and thirteen mechanisms are referenced only through their owning rooms; this article adds none.

Nothing here establishes that the chains are discoverable, that the corrections land, or that any scene is affecting. Those need later owner-authorised implementation and observation, and none has occurred.
