| **Bounded ordinary launch** | Under [Mechanical Interfaces And Opening Quantities](/Hold%20The%20Flood/Mechanical%20Interfaces%20And%20Opening%20Quantities), one active rig supports one independent ordinary launch path sourced by Threat Sensor or qualifying grounded-movement Stride. One designated ordinary actuator owns target/readiness; its valid target and one readiness spend seal one reservation. | No target means hold ready. When the reserved wave reaches the designated actuator through any Fork, it launches exactly once without rechecking the spent readiness. Other descendants check independently. A second independent source-to-ordinary-launch path refuses before edit commitment; manual sources, non-launch Stride responses and Projector descendants remain legal. |

The nearest-visible rule remains a provisional targeting default, not a claim of optimal targeting. Priority choices, manual overrides and accessibility assistance remain interface decisions. Current encounters use the bounded one-independent-launch envelope; this does not forbid an unrelated manual source or non-launch descendant.

**Perception and timing.** It follows local sight/sound. If a visible control becomes active within its room, it faces the astronaut operating it. During the crouch, the landing arc follows the operator until the clamp jaws flash; that flash locks the arc to the astronaut's current position. Cancelling before lock makes the inactive control ineligible, so the Crawler drops the crouch and resumes pursuit without leaping. After lock, cancelling does not stop the committed leap: moving outside the fixed arc makes it miss and skid through recovery, while remaining at the control lets the body strike and jaws catch the panel. A latched Crawler occupies the control until displaced or defeated; after removal it rights itself before acting again.

**Choice and responses.** Begin work to draw the crouch, wait for the visible jaw-flash lock, then cancel and leave the fixed landing arc so it skids; alternatively interrupt/defeat it before commitment or clear it before working. Manual Barrier can intercept the committed body and Manual → Nozzle can displace it. The baseline lock-read, movement and cutter path uses no unique equipment. No cancellation or occupation erases an already completed checkpoint.

**Perception and timing.** With sight of the astronaut and at least one visible allied creature behind the previewed sheet, it winds up by extending the two anchors, commits one fixed veil between them, then remains unable to cast while the veil's shown edge decays. Collapse is followed by a brief refold recovery. Losing the eligible ally, losing sight, displacement or defeat before commitment aborts the cast; moving the bearer afterwards does not drag the anchored sheet.

**Wind-up, action and recovery.** At the start of the visible plant/dust-draw warning, Bellback faces the last-seen point and the cone direction locks. The bright ripple fills within that already fixed cone. Completing the brace releases one pressure wave through it, then the chest collapses and it must unplant/refill before another brace. Leaving the cone or reaching hard cover avoids the release without cancelling it; displacing or defeating Bellback during brace interrupts it.

| **R1 / 2. Pace calibration / placement 2** | One Boltspitter with a single pillar teaches sac fill, final line lock and cover before the service-belt comparison. If objective 5 was reached first, this remains a low-pressure reinforcement rather than a prerequisite. | A Presser makes standing still for the gait record costly: clear it, bait the bolt, or defer. | Single-detent Sterilization Carousel. Cool detent and Boltspitter refill are separate visible windows; the same astronaut comparison remains possible without combat gear. |

**Two-order cue check.** Build-and-ship-first still sees Boltspitter at 2 before 5/7, Flanker at 4 before 6 and Bellback at 8 before 11. Language-and-network-first instead gets the always-authored separated Boltspitter and eligible Veilbearer cue bays at 5 before their pair at 7, and the Flanker-only long-approach segment at 6 before its valve mixture; 2 and 4 later reinforce those cues. These are spatial staging obligations inside placements 5 and 6, not journal-learned flags, new prerequisites, populations appearing from nowhere or extra objectives. The main Receiver Vault uses Siphon/Shutterback, whose separate placements 6/9 precede 11 in both orders; the cheaper Bellback substitution supplies its own threshold rehearsal below rather than assuming objective 8 was visited.

**Genuinely cheaper alternative: 6 ordinary / 2 special / 1 setpiece.** Retain all six ordinary roles plus Bellback and Glass Siphon. Omit Shutterback from the selected SMALL roster while preserving its source proposal for later consideration; Veilbearer carries the simpler sight-pressure function. Convert Balance Gallery from a major setpiece to an ordinary Bellback/mechanism placement, and retain Receiver Vault as the only setpiece using Bellback/Siphon rather than a fan. Its threshold must stage Bellback alone across one fixed pillar for a full warning-start lock, release and recovery before the Siphon line can overlap; both creatures are visibly present and no spawn is triggered. This self-contained rehearsal means the cheaper vault does not depend on objective 8, but it consumes part of the layout saving. The alternative still removes one special adaptation and one bespoke staged layout, at the cost of less dynamic angular cover, spectacle and escalation. It does not promise retained playtime, add enemies elsewhere or turn the short rescue into compensation.

**Overlap accounting.** Combat Rules already owns general perception, targeting, alerts, interruption and return; this page consumes the accepted bounded ordinary-launch compatibility rule and does not rewrite its parent. Traps And Encounter Progression already owns five families, the regional pressure rhythm and the first Pressure Gallery trace; setpiece A specializes that existing trace at objective 8 rather than adding a third setpiece. Horde Creature Proposals supplies the three special behaviors; this page classifies, allocates and integrates them rather than claiming three wholly new designs. Equipment Catalogue and Acquisition own parts, C/A and legal rig paths. Player Information owns cue presentation/accessibility equivalents. Save And Content State owns identities/transaction consistency.

**Unique v1 increments.** This proposal adds three ordinary role definitions (Boltspitter, Clampcrawler, Veilbearer), scoped combat-state/placement extensions for the three existing ordinary roles and three existing special briefs, one shared combat-state sheet, ten encounter allocations inside existing objectives, and two setpiece specifications included within those ten. Cross-order integrity adds two separated cue bays/fixed separation at placement 5 and one separated approach beat at placement 6; the cheaper roster carries one conditional Bellback threshold rehearsal. These are geometry/staging work inside already counted placements, not new encounters or rooms. The proposal adds zero regions, objectives, rooms, language/mystery chains, survivor scenes, equipment definitions or mechanism families. The setpieces reuse objective 8's Phase/Breath work and objective 11's pressure iris; their exact room geometry remains part of the future room/instance ledger and the twelve placed-mechanism inventory, not silently completed here.

This outcome advances the combat/interface/roster remainder of Production Scope's combined **Acquisition, build/combat interfaces and roster** row after Acquisition 26; it does not reopen or add the full Catalogue, Acquisition, Traps, Regional, Player Information, Save or older outline estimates. Remaining finite authoring is ten encounter-placement briefs with exact permitted geometry/populations/cue variants and recovery access; two setpiece room layouts satisfying the obligations above; role-specific presentation equivalents; encounter combinations against the final twelve mechanism placements; and, only if later content exceeds the accepted envelope, a new multiple-independent-launch policy. TARGET/STRETCH roles and variants remain unestimated.

All nine roles have a silhouette/warning, local perception, wind-up/action/recovery, effect on astronaut/work, interrupt/avoid/defeat conditions, player choice, manual rig response, no-unique-part baseline and causal-wave/Dynamo boundary. Veil casts now name an eligible ally; Clampcrawler locks the operator position and distinguishes cancellation before/after commitment; Bellback locks its cone when the warning begins. The allocation uses all nine roles across four regions, assigns ten encounters to existing objectives, counts two setpieces inside that ten, adds no encounter at ship-side objective 10 and invents none for unresolved objective 12. Both retained Regional orders receive low-pressure Boltspitter and Flanker cues before their mixtures without objective or learned-state gates. At least placements 6, 8 and 9 change persistent work or evidence decisions. The revisit compares two legal 6 C/6 A rigs and conserves material/property. No controller-free or double-resolved shot, global Dynamo, Fork amplification, remote drain, punitive counter-spawn, mandatory equipment gate, death material penalty, rescue exception, story truth or ending lock was added.

Open decisions/interfaces are target override/assistance; any later expansion beyond one independent ordinary-launch path; exact warning and recovery timings; damage, health, displacement and population; line/cover/camera rules; Barrier eligibility; Siphon drain presentation; Veil/Shutter visibility distinction; origin evidence and cast interpretations; alive-return populations; exact room geometry and shift-valid access; mechanism-instance allocation; performance/effect density; and acquisition/capacity values. Later owner-authorised implementation and observation with real players must establish readability, accessibility, combat value, build dominance, low-power viability, pressure pacing and performance. This paper contract proves none of them.
