M-17 Off-Axis Double-Body Collision / M-17 轴外双身碰撞线

The repaired prop mirror M-17 creates a physical source collision before any permission question begins. Nera Quill’s tape row records a clear safety laminate and a 17.4° hinge stop fitted after a crack. It does not record that the laminate sits six millimetres in front of the rear silvered sheet, creating a displaced secondary reflection.

During source take D17, Camera A sees the lead directly on hero spike H-3. Camera B, using a 50 mm lens off axis, sees the lead through the front reflection and understudy Lian Mere crossing safety lane S-2 through the rear-layer path. Recap R4 crops and reverses the Camera B insert, then reads both simultaneous bodies as one lead occupying incompatible positions.

The playable pressure is therefore not whether repair tape grants likeness consent. It is whether production preserves a one-take specular ray-path ledger before a composite mirror image becomes a canonical broadcast body.

Distinct seam boundary

This storyline must remain narrower than its adjacent lanes:

• Makeup Mirror Tape Afteruse Receipt governs written likeness and custody scope on saved dressing-room tape. M-17 governs a measured optical path; it does not certify consent.
• Stage Spike Mark Afteruse Receipt and Scene Change Tape Afteruse Receipt govern later use of blocking marks and camera-placement authority. Here H-3 and S-2 are coordinates in a ray map, not authority tokens.
• Prop Continuity Afteruse Receipt governs generic reuse of a marked prop. This line requires two simultaneous bodies, two reflective layers, a named camera/lens path, and a composite edit.
• Mirror Right Boundary Audit governs contractual near, exit, staging, and naming rights. Those rights cannot explain glass, parallax, crop reversal, or secondary-image displacement.
• Wardrobe Laundry Batch Identity Collision reconstructs which garments and performers belonged to a contaminated batch. M-17 reconstructs how two already-located bodies entered one image.

The line fails its identity if it collapses into certify scope, restrict reader, reopen a generic claimant, split likeness from custody, or quarantine an old tape row. Its branch states must change optical topology, source-master handling, or the fate of the physical secondary body.

Playable question

When M-17 makes lead and understudy simultaneously visible through different reflective layers, does production bind the take geometry, reblock only a new take, replace the reflective layer and destroy trace, split the masters, name Lian as the reflected performer, reshoot on a truthful axis, license one scoped double-body effect, or suppress the map and let a phantom lead harden?

The line does not open merely because a prop mirror, repair row, performer, or reflection exists. It opens when the named source geometry and named edit reuse expose a live one-image/two-body collision.

Bound content pack

• M-17 Specular Ray-Path Ledger defines the optical topology, exact assignment, irreversible trace rules, and local authority boundary.
• M-17 Off-Axis Double-Body Docket binds mirror version, construction layers, hinge angle, body coordinates, Camera A/B paths, take D17, recap R4, and future readers.
• M-17 Specular Ray-Path Review resolves eight distinct optical, production, edit, credit, or default postures from eight exact cards.
• M-17 Phantom Lead Hardening forces either secondary-path reconstruction or admission that the composite body hardened and overwrote Lian’s reflection.
• M-17 Reflection Topology Lens observes reachability, branch non-equivalence, destructive tradeoffs, authority denial, and runtime evidence.

Story spine

Beat 1 — A safety repair creates an unlogged optical version

The source row proves who repaired M-17, what laminate was fitted, and where the hinge stop was set. It does not prove what Camera B sees through the new front/rear layer separation. Prop repair and optical topology remain separate facts.

Beat 2 — Two body coordinates enter one take

The Camera A/B map keeps lead H-3 and Lian S-2 distinct. Both bodies are physically present in D17; the rear-layer ghost path displaces Lian by 41 pixels in Camera B. Lian’s claim is body-location evidence, not identity or consent authority.

Beat 3 — The edit turns a topology error into one performer

Recap R4 crops and reverses the Camera B insert. The composite reader calls the result clean lead continuity even though the reflected torso and movement occupy incompatible coordinates. Sponsor and archive masters are queued to inherit that edit.

Beat 4 — Review chooses what changes

Run M-17 Specular Ray-Path Review. Some branches preserve old evidence but delay reuse. Reblocking repairs only a new take. Replacing the rear layer prevents future ghosting but consumes the original optical trace. Splitting masters keeps the source distinction at edit cost. Naming Lian breaks the lead-only fiction. Reshooting spends a production slot. A scoped effect carries dual-persona liability.

Beat 5 — Suppression makes an impossible body real

If production hides the ray-path map and airs Camera B as one clean lead body, M-17 Phantom Lead Hardening fires. Later play must either reconstruct the secondary path or preserve an admission that broadcast reality hardened a phantom lead while overwriting the understudy who physically generated part of it.

An accurate ray map can prove how light from a named body reached a named camera during D17. It cannot decide who may be represented, credited, licensed, edited, archived, or broadcast.

Missability and recovery

The collision becomes missable if the rear layer is replaced before the laser-grid survey, the Camera B crop loses its source-take link, Lian’s S-2 crossing is erased from the body-coordinate row, or R4 is reused before the docket opens. Reblocking or repair cannot retroactively clean the old master. Once both geometry trace and source edit map are gone, recovery proceeds through public admission, performer correction, disputed-master handling, or a future ray-path reconstruction cost.

This is not a recruitment storyline. Lian Mere and Nera Quill are evidence-bearing existing roles; resolving this docket does not recruit either person or manufacture their consent.

Replay expectation

The durable replay must place all eight exact source cards in the current hand, assign them to their exact slots, select survey_and_bind_take_geometry, and emit take_geometry_bound plus mirror_geometry_checksum_required. Focused runtime evidence must also execute all eight branches, reject missing, duplicate, catalog-only, or arbitrary slot substitutes, reject omitted choices, prove the destructive rear-layer branch, and execute both default outcomes.
