Every discovery context identifies somewhere the behavior could be observed. It does **not** decide whether the player claims the functioning object, retrieves a damaged core, fabricates it after observation or receives an adapter. Found-part versus fabrication progression remains open.

| **Pulse Projector** | One packet input; on a valid trigger while ready, launches its payload toward the selected valid target, or a weak force pulse if none is attached. Its launch is physical output, not a signal port. Rebound Disc, Foundry Drop and Furnace Burst temporarily supply their named finite disc or lance behavior. | Reach, readiness and a weak pulse against a service target. | **1/1.** One selected target, line of sight and world-time readiness; physical flight does not retarget after commitment. A disc keeps its operating reservation through its last fragment. Sparse angles or obstruction waste positioning, not ammunition. | Sensor → Projector for baseline fire; Capacitor → Thermal Lens → Projector for a manually released heat shot. | Ship rig or station service cradle; distinct from the unported worn cutter. |

| **Impact Dynamo** | One local sensing clamp plus one charged-trigger output. The clamp attaches to one named impact carrier: a Barrier frame, a Projector's physical-output feed or a fixture surface. It batches qualifying impacts there and emits once for that wave; it does not hear remote world impacts. | A door closer converts hits on its own plate into one charge flash even when fragments arrive together. | **1/1.** One attached carrier at a time; force, fragments and external strikes qualify, while arcs and heat do not unless converted. One eligible wave emits proposed **2 U** regardless of how many same-wave impacts were batched. Descendants of Thunderhead, Foundry Drop or Furnace Burst are ineligible to recharge it, including after automatic connections restore. | Projector impact feed → Dynamo → Arc; Barrier frame strikes → Dynamo → Capacitor. | Impact latch in a service door or bed-crash protector. |

| **Capacitor** | Charged-packet input, exact **0–4 U** stored state, chosen release trigger and one charged output. Ordinary manual release is exactly **2 U**; release caused by a rig packet retains that packet's wave. Becoming ready/full emits nothing. Temporary Thunderhead, Foundry Drop and Furnace Burst are explicit full-store **4 U** exceptions, each supplying its own two gated modes. | Rising meter, visible saturation and a controlled discharge into a dead load; when a full-store transformation is active, its charging or discharge mode is also visible. | **1/1.** Accepts at least 1 U up to free space and visibly vents delivered overflow; at 4 U it is blocked before Fork allocation. An ordinary release below 2 U or toward a refusing first receiver does not commit and retains charge. A refused full-store command retains 4 U and charging mode; an accepted one restores charging after dispatch without granting readiness. | Dynamo → Capacitor for horde-fed storage; manual release → Lens → Projector for a burst. | Defibrillator bank, door buffer or damaged core whose stored state stays visible. |

| **Stride Switch** | Source; one trigger output after the astronaut deliberately traverses a shown distance while grounded and the switch is ready. Rig-produced shove, knockback and conveyor motion do not count. Temporary Inward Draft changes only a Stride-sourced Nozzle action; it does not make forced motion an input. | A rehab gait plate pulses after measured voluntary steps but ignores a rolling bed. | **1/1.** Silent while stationary, displaced or below threshold; its own descendants cannot walk it into retriggering. | Stride → Projector for kiting fire; Stride packet triggers a configured Capacitor release into Barrier while relocating. | Physical-therapy gait monitor or maintenance pace counter. |

Before a manual discharge, the player faces or positions the relevant actuator and sees its selected valid target and readiness. With no acceptable first receiver, release refuses before starting a wave or spending stored charge. A later refusal after release commitment does not restore charge.

**1. Four-space opening branch — optional reconfiguration.** Move Manual Trigger to inactive cargo, mount the found Fork in live world time, then use the paused journal to link **Threat Sensor → Fork → Pulse Projector + Barrier Plate**. Cost: 4 A and 4 C active, plus the inactive Manual Trigger still using 1 C. Sensor offers one target-conditioned event; Projector and Barrier check independently. Projector fires when its own target/readiness accept. A ready Barrier also acts; an unready branch does nothing and queues nothing. A different legal rig could contain two ordinary actuators if both sources, targets, readiness, carrying, active space, power and heat fit.

**2. Six-space later Counterwall — defence becomes storage.** Under the proposed navigation-coupler **6 A** ship configuration, install Manual Trigger (1), Barrier (1), Dynamo (1), Capacitor (1) and Arc Emitter (2). Manual Trigger → Barrier is a faced manual special. Dynamo's clamp is attached to that Barrier frame. Each later enemy strike is a separate external event; Dynamo emits exactly 2 U for that eligible wave, and Capacitor stores up to its 4 U limit. A later built-in manual 2 U Capacitor release starts a new wave only after the ready, targeted Arc accepts as first receiver. The rig trades all six spaces/units for faced defence and dense-target discharge; attacks stopping, barrier failure, sparse enemies or saturation break its payoff.

**Ricochet Foundry.** Sensor (1)→Projector (1), with Projector impacts→Dynamo (1)→Capacitor (1), supplies automatic fire and storage. Manual (1)→Nozzle (2) provides a separate shove. Total: **7 C / 7 A**, or 9 C with one canister. **Rebound Disc** follows a finite physical path; stationary hard faces bank it only where the preview shows a clear reflection. Other finite endings are marked terminals. **Fragment Wake** adds a forward fan at every normal terminal. **Foundry Drop** sends the full store through Capacitor→Projector for a larger master disc with the same bank/terminal behavior. The player runs for angles and shoves eligible bodies or loose cover into useful positions; Nozzle never steers the disc. Open space and a fan facing into cover can spoil the setup, and using the shove early spends an escape option.

**Gravity Furnace.** Stride (1)→Nozzle (2) provides outward movement pulses. Sensor (1)→Projector (1), with Projector impacts→Dynamo (1)→Capacitor (1), charges the store; Lens (1) is mounted for conversion. Total: **8 C / 8 A**; one canister fills all ten carrying units. **Inward Draft** turns only Stride-sourced pulses into a rear pull, with opposite reaction on the astronaut. Fresh voluntary movement is required; forced motion never retriggers it. **Furnace Burst** sends the full store through Capacitor→Lens→Projector for a heat lance and bloom. The player gathers a dangerous wake, then releases or escapes. Fixed or sealed objects stay put; hard cover divides the effect.

Repeated arcs, rebounds, penetration and blooms use the named finite route/body allowance. Arc Emitter's ordinary physical arc has no signal output. A descendant cannot refresh its own readiness or allowance, release an in-flight power reservation early or mint usable U. Dynamo contributes at most once for an eligible external wave. Becoming full or ready never makes Capacitor emit. Thunderhead, Foundry Drop and Furnace Burst descendants remain excluded from Dynamo even after charging mode restores. Ordinary later impacts or enemy attacks may charge storage as distinct external waves, only while their local carrier and receiving gates hold. A stopped route does not refund committed charge or heat.

The provisional stage-only reward model offers temporary effects after resolving one finite announced pressure release from an identified physical source; a stage is uncommitted, unresolved or spent for the current station arrangement. A physical closure completed before commitment prevents the release and gives no offer; lasting safety/access is the benefit. After commitment, early clear or a physical source seal resolves the stage even before its peak, while bodies already beyond the closure remain dangerous. Escape does not resolve it, and a spent stage does not pay again after a living return or reopening. The owner is still choosing this rhythm versus regular defeated-enemy growth plus larger milestone transformations. No meter, threshold, pickup cadence or interruption cost for that alternative is invented here.

Open questions include acquisition model, true active area, part shapes, port multiplicity, target override, fixture eligibility, removal consequences, discovery order, final power/heat/route values, retained Capacitor charge and the pending reward rhythm. The quantities above describe inspectable comparison cases rather than tuned results. Exactly twelve physical parts and their existing sources, costs and property consequences remain. Multiple ordinary outputs are legal within physical limits; Echoing Arc, Rebound Disc, Fragment Wake, Thunderhead, Foundry Drop, Inward Draft and Furnace Burst are temporary effects, not new permanent parts or universal Capacitor modes. Each expires on return aboard.

Later owner-authorised implementation and real-player observation must establish whether individual parts are legible, multiple target/readiness displays remain readable, combinations remain expressive without one dominant path, costs compete meaningfully with oxygen and loot, paused link edits are usable, and rare station uses feel revelatory rather than like metadata keys. None is established here.
