It screens final TCP +rolls and emitted close commands, including after plan transforms; it neither +changes proposals/RNG nor replaces native acquisition/retention evidence. Both +markers default to absent for legacy equivalence and are independent of recipe +composition. Neither discrete screen proves continuous collision freedom. +`pick_contact_revision=2` additionally rejects nonpad native contact-halo entry +strictly before the sampled bilateral pad-rest boundary; potential halo overlap +at that boundary alone does not establish actual contact. Nonpad rest intrusion still +rejects at the boundary, and runtime bilateral acquisition/holding gates remain. +`pick_contact_revision=3` retains revision 2 and additionally screens the nominal +opening prefix against the exact rigid support of a bound ordinary on-Place. +Only source-qualified candidates enter this check. Native rest-envelope overlap +rejects; contact-halo proximity is diagnostic. This discrete geometric screen +does not replace measured release, separation, retreat or support evidence. +Explicit revision 4 combines revision 1's source rest-contact ordering with +revision 3's opening screen. The first nonpad contact halo before or at pad rest +remains diagnostic, not a collision certificate or standalone veto. Nonpad rest intrusion, +missing bilateral pad rest and all measured acquisition/release/support gates +still reject. Revisions 1/2/3 and the normal workflow's selection are unchanged. +Non-E1 and legacy bundles without TaskSpec retain their prior gates. + +Explicit `upright_container_picks` maps selected E3 Pick node IDs to a maximum +pad-closing-axis tilt above the Z-up horizontal plane. It requires native Pick +closing geometry and is absent by default. Named cooked-pad geometry and nominal +FK define the axis; no universal TCP-X convention is assumed. The same mask runs +on candidates and emitted close FK, including after plan transforms. This grasp +quality rule is separate from native contact/rest safety and never replaces +acquisition or retention evidence. Undeclared Picks and shared GraspKit defaults +remain unchanged; regenerate consumers to opt in. + +Explicit Pick contact revision 5 retains revision 4 and requires the native open +pads to be outside the target rest envelope. A call-owned proposal view may then +replace whole-object aperture fit with exact native open/close geometry, allowing +local rim or handle grasps without changing the shared generator. Revision 6 also +tries bounded grasp depths measured from the named pad span and pair rest offsets. +Original strategies remain first, accepted commands are cached unchanged, and +additional complete paths share the existing four-recovery budget. Extra depths +reuse the original geometric pools, branch keys and IK random states rather than +regenerating approach proposals or advancing unrelated random streams. Ordinary +Pick checks its already-required open-hand endpoint scene clearance before accepting a +depth; this introduces no new scene gate for Pour. Constraints and explicit grasps +retain their original depth. Handover end regions and owned Cartesian routes also +retain it unless the native8 source contract described below is explicitly enabled. +These opt-ins do not replace native acquisition, retention or final path checks. +Revision 7 also screens the fixed-arm nominal pre-contact closure against the scene +for ordinary native B1/env0 Picks, both during candidate choice and on emitted +plans. The read-only scene view permits intended source contact only in that +interval up to the first nominal bilateral rest sample; the open endpoint still includes the source and the native closing +screen owns every hand/source pair. Other objects, articulations, self/other-arm +checks, depth budgets and physical collisions remain unchanged. Post-contact +command FK is not a physical-penetration forecast: an acquired object can stop +actual closure before its command endpoint. Pour retains +revision 6 behavior. This option does not certify dynamic obstacle prediction. + +Explicit Pick contact revision 8 retains revision 7's native geometry and runtime +gates, but its call-owned center-proposal view delegates the approximate source +proxy veto to the existing native cooked-hand/source qualification. +`pick_proposals.py` consumes GraspKit's cached `prepare_mesh()` contact pairs; +GenSim owns the resulting pose proposals, costs and truncation. Shared GraspKit +interfaces and defaults remain unchanged. These unqualified proposals cannot +bypass ground or end-region policies, and transformed candidates and emitted +closing commands must still pass the native screen. Non-native views and +revisions 1--7 retain their original proposal behavior. The screen records actual +proposal calls so configuration alone is not mistaken for an activated route. +Native center proposals retain their raw costs until the owning Pick applies +the current TCP transform and both roll variants. Native source/quality +qualification precedes the provider's configured candidate cap and shared IK; +unqualified proposals cannot consume every retained slot. Each existing depth +uses the same raw pool with its own transform. This does not add full-path +retries or change ground/end-region policies or the four-path recovery budget. +The unchanged inexpensive direction mask short-circuits native geometry queries +for already-incompatible columns; it adds no new acceptance condition. +Qualification follows the original stable cost order and stops when the +configured number of valid candidates is filled. This is the same qualified +top-k set as an exhaustive screen, without checking a provably higher-cost tail. +Ordinary B1 Picks without continuation previews or affordance branch sampling +qualify and solve candidates +in stable-cost batches of at most 50, stopping at the first IK-feasible batch +before invoking the existing full-path checks. The configured qualified-candidate +cap is still an upper bound, not a required population. Other callers retain the +exhaustive qualified top-k selector. +If the selected path or its full safety qualification fails, the original raw +pool and pre-IK random checkpoint restore that route's complete qualified-cap +population in place before the existing filtered recovery. This preserves +candidate coverage, not bitwise equivalence of random full-path planning. +Failed-path raw recovery qualifies individual +TCP rolls on demand in the existing cost/nearest-roll/route order; it does not +scan every raw route before applying the shared four-path budget. No native +source/scene check or execution gate is removed. +Revision 8 also checks the same native cooked hand against other rigid bodies' +actual pair rest offsets over the original precontact grid. Source contact +remains separately owned; the existing robot/articulation/proxy checks remain. +The scene snapshot is invocation-local and read-only. Emitted and transformed +closing plans repeat this qualification; it does not predict post-contact +dynamics or certify a physical grip. Revisions 1--7 retain their existing checks. + +Per-call `pick_contact_revisions` also accepts revision 8 for generated E4 +handover-source registered Picks. The lowerer's `ends` contract opts these calls +into the same open/precontact and emitted/transformed closing-scene checks. +Bounded depth search reuses the selected `supported_end` candidate pools and +shares the existing four-path budget, including owned Cartesian source routes; +it does not switch to ordinary center proposals or relax receiver selection. +Other registered calls, legacy E4 without this opt-in, Pour, and shared PickUp +defaults are unchanged. Geometry qualification still requires physical +acquisition, holding and subsequent HandOver verification during execution. +Regenerating an expanded E4 graph preserves its declared MoveHeldObject transfer +poses; upright landing refinement must not lower or rotate those transfer targets. + +Explicit `post_handover_places` permissions bind only adjacent sequential +HandOver-to-relative-on Place calls with the same rigid object and exact receiver. +On real-held planning failure, the declared Place may reuse the existing +goal-conditioned waypoint branch with its observed `ends` grasp and preserved +release orientation. The normal Place attempt and successful plans remain unchanged. +For a singleton release goal with two Cartesian keyframes per translation, the +recovery distinguishes the generated free-transport midpoint from the original +preplace/contact/release targets. A fresh payload-aware cuRobo connection replaces +only that midpoint; continuous seeded IK retains the exact Cartesian descent and +reverse empty-hand retract. Explicit phase composition preserves passive and +release commands/effects, remaps phase-boundary monitors, and may extend only the +approach within the original action timeout. Final FK, velocity, robot mesh and +scene-envelope checks still qualify the emitted commands. Other waypoint branches +retain their fixed phase grids and fail closed when duration is insufficient. +The same explicit route also binds the preceding HandOver: an `ends` grip keeps +its inverse-grasp withdrawal before the final two waypoints move outward toward +the source arm's side by the existing retreat distance; a planned exit robot-mesh +gate participates in the existing bounded direction retry. Ordinary/default calls +remain unchanged. These planning receipts do not certify physical acquisition, +release or task success; complete native execution and TaskSpec remain required. + +The packaged Task Engine CLI defaults select +`planning.runtime_profile: auto` and +`execution.acceptance_mode: experiment`, including when `--config` is omitted. +Explicit YAML overrides may select `default`/`strict` or +`composition_experiment`; omitted fields in override YAML and direct Python +configuration construction retain their legacy defaults. The CLI defaults and +both packaged experiment YAML files bound preparation to one worker, one scene +attempt and one action attempt. Experimental acceptance requires one environment; +vectorized legacy execution needs an explicit strict configuration. +Only the contact profile adds a material-only Robotiq pad +overlay (static/dynamic friction 2.85/2.70); composition retains original materials. +Automatic selection uses the validated recipe: any E3/Pour selects composition, +pure E1/E2/E6 recipes retain the original default grip policy, and other recipes +retain contact. It never tests task IDs, object UIDs or text-name heuristics. +The automatic ordinary policy still uses the authorized 100/100/30 mm supported +placement tolerances. Explicit profile overrides remain unchanged. +E3 auto-arm preference uses the existing source/receiver midpoint rule; explicit +arm requests and the owner of an already-held source keep precedence. This is +only a preference, not a reachability certificate; native continuation and +actual held-state planning still qualify the complete route. +Only a failed, single-environment retained E3 arc rejected by joint-velocity +qualification may reuse the existing continuous seeded IK resolver. It retains +every Cartesian target, the observed start, frame count and time grid, checks +the full emitted robot proxy, and keeps native retention gates. Owned E3 planning +shares the 90-second cooperative wall limit; successful and legacy Pour paths +remain unchanged. This does not certify arbitrary scene collision or fluid transfer. +The generated constraints bind the concrete profile; `runtime_profile_selection.json` +records the request and selection. Explicit profile overrides remain unchanged. +One bundle has one material policy, not dynamic per-call switching; mixed recipes +containing Pour retain composition and require their own physical qualification. +Both profiles use 100/100/30 mm COM/position/support tolerances +for supported on-placement, independently of final TaskSpec acceptance. +Experimental ordinary relative-placement stability post-policies use the same +100 mm position bound as their generated near-relative-target validators; +hold, alignment, collision and velocity contracts are not relaxed. +Generated handover contact revisions compose with existing occurrence permissions; +different revisions for the same call reject rather than replacing an earlier +selection. It derives horizontal end-grasp HandOver/Place +permissions from exact adjacent occurrences, not task IDs. +Authorized horizontal-transfer receiver Places retain ordinary 140-point free +transport even if the model groups them inside E4; they cannot inherit the +transfer group's Cartesian approach. HandOver and its source/staging stay +unchanged, and terminal descent/release/withdrawal checks remain required. +Related auto-arm Pour source/receiver reuse and terminal same-object reacquisition may add a +visible empty-arm clearance/restore pair. Its finite proximal-joint proposals +are ranked by FK endpoint separation, screened against the current scene and +rechecked on emitted (including transformed) MoveJoints trajectories. This is +a bounded heuristic, not a complete bimanual planner or stability guarantee. +After an ordinary on/inside release onto an unmoved reference, later E1 +collection may prefer the arm nearest both that reference and the unmoved target +over the earlier Pour arm. Rehandling either subject or reference invalidates the +location hint; explicit arms, live holders and resource occupancy remain authoritative. +Composition keeps original Pick closure and total sample counts. Its effort +calibration applies only to a resource that actually picks an E3 pouring payload, +when all its picked bodies and E5 carriers have known masses of at most 10 g. +That resource caps effort at 5; unrelated Composition hands retain canonical +limits. Empty-hand E9 does not block this pour cap; E4/E6/E8 and unknown action +families do. Other Default and Contact resources retain existing calibration. +Contact-profile qualified light E1/E2 grips cap actuator effort at 5 rather than +0.5; Default retains 0.5. Both preserve any lower authored limit. Unknown/heavier payloads and blocked recipe resources +retain their original limits. This is not an acquisition or holding exemption. +Contact also retains its qualified 24-point ordinary Pick closure with 12 extra total samples, +leaving approach/lift counts unchanged. Frozen physical inputs reject these opt-ins. +`planning.experimental_open_release` independently selects the release observer; +packaged defaults leave it null, deriving false for the resolved default profile +and true for Contact/Composition; an explicit false still keeps revision 1. +Both explicit experiment configurations set true. +Old bundles and direct builder callers that omit the marker retain their original +profile-based release selection. Its native grip observer revision 2 permits an experimental detached +observation when the measured independent URDF driving joints are within the +profile's existing open tolerance and exactly one pad remains in contact. +Acquisition and holding still require native opposed bilateral contact; +nonfinite, dropped, bilateral or non-opposing two-pad observations cannot use +this release rule. Raw contacts and measured opening are recorded. This means +open-hand loss of bilateral grip, not contact-free separation; actual retract, +placement and settling still execute. Default revision 1 remains unchanged. +Frozen physical references require runtime_profile=default and reject incompatible +profiles before any model calls; coordinator and bundle checks remain in place. + +Explicit experimental acceptance requires complete native program execution, +all original segment/post-policy/validator checks and cargo acceptance; only +the outer TaskSpec certificate is advisory. The canonical runner preserves +`task_spec_evaluation.json` and publishes `strict_execution_report.json` beside +the clearly marked experimental report. Both `run` and `run-all` use this same +production path, without importing artifact-directory workers. Every execution +also writes program_completion_summary.json, separating program completion from +strict success without re-executing or replacing the selected verdict. The CLI +default reports experimental program completion; strict TaskSpec certification +remains separate and can still be selected explicitly. + +`generate_task_program_bundle(verify_pick_phases=True)` explicitly enables +registered Pick acquisition/lift verification through its fingerprinted lowerer +declaration. The default preserves legacy factory identity; closing geometry, +alignment, release and support contracts are independent. Phase ownership and +assurance are defined by [Task Program execution](../task-programs/execution.md). +Normal Task Engine preparation opts new bundles into this contract. E8 regeneration +preserves the input declaration; mixed per-Pick modes require explicit handling +and are rejected by the uniform generator rather than silently weakened.

Their scene config carries `world_alignment_applied`; preserve +it through edits so already-normalized poses are not rotated again. +Generated deployments retain the measured settled layout instead of teleporting +objects back to configured X/Y after settling. +Invocation-scoped Cartesian policy also covers single-EEF-target transports; +joint targets retain their joint-space behavior. E2 alignment preserves the +acquired orientation during the staging lift, then turns the object aloft. +E2's upright goal does not impose an initially fallen source pose: prior steps +may change the object's orientation. Grounding preserves the full object reference; +the existing runtime alignment and upright checks still execute without goal-based skipping. +E2 checks its final yaw-free alignment at release height before Place preserves +that heading. Alignment staging never descends below the current height before +the planner can choose the final orientation. +Ordinary GenSim Place retains its qualified initial Cartesian result.

Acceptance +checks final emitted velocity/joint limits, discrete robot meshes, and the held +object's conservative scene envelopes through approach. Overlapping AABBs are +refined with convex-solid covers of the same complete source vertices, retaining +the 2 mm separation requirement. Containment, unavailable geometry and unresolved +distance reject; this is not native contact or continuous collision certification. Explicit Cartesian +routes, dynamic collision policies, drawer routes and E2 z caps are not overridden. +Motion validation revision 15 preserves the original gradual hand opening when +ordinary Pick rebuilds its free-space/contact approach. It resamples opening +alongside the replacement arm path instead of holding a previously closed hand +until the close boundary; the exact grasp branch and close/lift suffix remain. +Full emitted velocity and discrete scene checks still qualify the rebuilt plan. +Rejected speeds report the emitting joint, frame, phase and ratio. Regenerate +bundles after this revision; old fingerprints cannot certify the new path. +Missing bound rigid geometry or bound articulation obstacles disable this fallback. +Motion validation revision 13 separately owns positively bound ordinary on-Place +calls with `preserve_current_object_orientation=false`, B1 and `ik_interp/off`, +excluding explicit Cartesian, custom-grasp, pour, upright and direct routes. +It retains a qualified initial dense plan unchanged. Otherwise one goal-seeded +waypoint solve replaces the density/local-IK/via recovery chain for that call. +The shared builder still owns commands, tracking and effects; phase composition +retains every mandatory pose and the original timing. Emitted FK, joint/velocity, +robot-mesh, payload-envelope and release-resource checks reject unsafe results +without another retry. This is not continuous collision or physical certification. +Ordinary held transport retains shared IK/interpolation, the existing target +construction, state handoff, general joint/velocity limits and effect monitors. +It has no additional carried-mesh sweep, robot-mesh path qualification, bounded +held-path recovery or post-transform collision recheck. Its completed motion +does not certify intermediate table, payload-scene or other-arm clearance. +`held_command.py` retains compiled same-object/resource source declarations; +these declarations alone are not runtime trajectory qualification. E2 alignment, +Pick, Place and handover keep their own checks. +Explicit `pour_geometry_revision=1` uses `pour_services.py` and +`pour_continuation.py` to bind ordinary orientation/axis/direction-free E3 to its +exact Pick, staging, Pour and absolute return calls. Staging preserves current +observed orientation; `pour_geometry.py` supplies the candidate-dependent +five-role look-ahead and actual tilt/restore geometry. Existing held G remains +the command-planning reference, not a native pose witness. Direction-free tilt +uses the ordered pad axis; receiver-bearing drift is diagnostic, not permission +to reverse the qualified arc. The new Pour lowerer +declares existing acquisition/retention verification, with no new executor or +path fallback. Adapter v14 requires regenerated consumers after the current +Pick qualification changes; historical bundles and receipts remain unchanged. +The independent +recipe does not own already-held E3 continuations; normal preparation +keeps those compositions on their legacy declaration rather than opting them +into a five-call contract they do not have. Native pose proxies do not establish +hand/cavity/collision qualification or liquid transfer. An unmodeled `poured` +TaskSpec remains unavailable; geometric motion +must not silently become its certificate. +Explicit revision 2 requires `pour_proxy_position_tolerance_m` and a distinct +`pour_region_transport` factory. Its runtime-only native vertices/triangles +snapshot is shared by Pick preview and the actual stage lowerer. The same pure +`pour_region.py` rule insets the receiver's actual triangle projection by that +declared position budget and chooses its arm-nearest point. It changes staging +XY only, retains observed R/height, and rejects an empty or invalid region without +falling back to the center. The active arm origin comes from its compiled motion +endpoint's solver-root frame. Explicit staging points and constrained E3 remain +unowned; legacy and revision 1 declarations/fingerprints remain unchanged. This +is a render-mesh target proposal, not an opening, collision or fluid certificate. +Region invocation metadata must bind the same position budget used by the +pose-proxy observer; that observer does not certify the original `poured` goal. +Bare `table/on` targets retain legal source XY; only occupied landings select a +measured free tabletop region. Fixed-base prismatic travel envelopes qualify +endpoints only. Named regions, explicit poses and E2 in-place goals do not move. +The bare E1 table route uses a `supported_region` preset: its planning point is +a proposal, not a normative coordinate goal. Live stability and TaskSpec join +exact native support, full measured planar footprint, contact height and release +evidence. Point/upright/named targets retain their prior constraints. Episode +geometry caches remove only exactly duplicated payload points; poses, contact +and acceptance are freshly measured on the unchanged stability cadence. +New bundles may explicitly request `support_contract_revision=1` from +`generate_task_program_bundle()`. `support_evidence.py` captures rigid-pair load +patches during actual physics substeps; `support_contract.py` binds their original +sample time, episode and actors to the exact release phase. The pinned Default +contact-cache revision getter is capability-checked; missing provenance is +unavailable, never a newly stamped cached observation. `stability.py` uses the +canonical acknowledged environment clock, and `task_spec_runtime.py` independently +joins historical terminal support and current final support. Strong declarations +cannot fall back to geometry-only evidence; unsupported relations or moving links +remain unavailable. The marker changes the bundle fingerprint, not physical +parameters or legacy default behavior. It is not itself native qualification. +Up to three shared waypoint plans may be compared for the same acquired grasp +and unchanged targets. Each must pass every existing safety gate. FK records +maximum/intermediate rotation, not just final heading; a low-rotation plan is +preferred, while the best qualified large-rotation plan remains the fallback. +Extra path searches restore the caller RNG and do not reselect a successful Pick. +Successful paths and failed-search random streams remain unchanged. This is not +continuous collision/contact qualification or a remedy for unreachable waypoints. +Ordinary, factory-marked single-environment GenSim Pick qualifies every contact +sample against its declared approach direction and selected grasp pose. A curved +contact leg is rebuilt backward from the original grasp joints through shared +Cartesian IK. Free-space entry targets that exact pre-contact joint branch, using +checked joint interpolation first and a fresh-world cuRobo plan if necessary. +The selected grasp, close/lift suffix, passive joints and shared executor remain +unchanged; emitted limits, robot meshes and all approach scene samples are checked. +Failed or unavailable qualification stops dispatch, not a fallback to the unsafe +original. Extra searches restore caller RNG. Explicit, constrained, upright, pour, +drawer and multi-environment calls retain their prior routes and bundle fingerprints. +After ordinary Pick path qualification fails, up to four other legally +prefiltered grasps may be replanned with their own approach directions. Distinct +wrist orientations are tried before near-identical poses, within the same +four-plan budget. Each +complete plan keeps its attachment proposal coupled to its commands and must +pass contact FK, emitted-limit and mesh checks; a bound Place continuation must +also pass its private preview. Successful originals are not reselected. +Failed ordinary Place may try two elevated approach vias, retaining every +required release waypoint, its exact terminal pose, source dependencies and +timing. These candidates require emitted-limit, robot-mesh, held-object scene +envelope and release-FK qualification. Explicit Cartesian routes, height caps, +drawer routes and pour/ends grasps do not acquire this recovery. Extra searches +restore caller RNG; no TCP symmetry is invented to make a target reachable. +`_task_program/motion.py` owns one bounded seeded-path resolver shared by the +motion-generator adapter and E6's root-frame IK adapter. Previous-waypoint +seeding, local perturbations, joint limits and per-step velocity admission live +there; E6 retains its final FK, complete-plan velocity and collision checks. +This is greedy local continuation using existing solvers, not a new IK solver, +global branch search or physical-success certificate. +Deployments with an ordinary Pick bind grasp constraint observations to the +queried object's two native finger-pad contacts on the queried hand. Positive +impulses and opposing normals qualify acquisition; absent contacts qualify +release. Outside the explicit experimental open-hand rule above, one-sided, +non-opposing, nonfinite or saturated observations remain unverified. +Shared pose-relation, consecutive-sample, lift and release monitors +are retained; a wide object does not need an arbitrary minimum closing angle. +This uses the canonical dual-Franka pad bindings and is not a new executor or +a certificate of complete-task success. Regenerate affected bundles. +Ordinary adjacent typed Pick/inside-Place calls with verified canonical monitors +may qualify the complete continuation before dispatching Pick. A qualified +original remains unchanged. Only a failed required-waypoint IK result permits +contact reselection; velocity-only rejection or unavailable evidence preserves +the original acquisition. Up to twelve existing legal grasp +contacts are considered, with full Pick/Place planning, emitted limits and mesh +checks; the semantic landing pose and resource bindings are never changed. +The preview projects the emitted Pick endpoint FK in private state and is not +measured acquisition evidence. Actual Place still observes and replans through +the canonical executor. This runtime-only binding adds no bundle fingerprint +fields and does not apply to upright, fixed, explicit, constrained or pour/ends +grasps. Collision evidence covers discrete robot self meshes and bound rigid +held-object envelopes, not whole-scene continuous or contact qualification. +Only yaw-free alignment calls enable alternative final headings; exact-pose +transport retains its orientation contract. All candidates use the same motion +and velocity checks. +Invocation-owned constrained center Pick also qualifies the complete emitted +approach, close and lift against robot proxies. A safe original plan is kept; +an unsafe successful plan may try bounded alternatives from the same filtered +grasp pool using the shared Pick planner. Explicit grasps, upright-rotating +Picks and downstream-lookahead Picks retain their separate contracts. Observed +start collisions and unavailable certificates fail closed. These checks do not +certify held-object scene contact or physical grasp success. +A free hand whose first open command alone exceeds the observed velocity +boundary may receive a bounded, real opening prefix within the existing hand +interpolation budget. The arm and passive joints hold their observed positions; +the original Pick suffix and attachment remain unchanged. The complete emitted +plan is qualified again, without treating failed attachment as held state or +changing the shared planner, command targets or velocity limits. +Yaw-free non-drawer GenSim held alignment also screens robot self/other-arm +proxies before accepting a heading. If the existing heading search exhausts, +one bounded local IK recovery may preserve the last heading's Cartesian path +and timing, including when every heading fails IK or velocity qualification, +or when raw IK succeeded but proxy screening rejected it. +An observed start collision does not permit that recovery. Extra searches +restore the first rejected legacy-stop random state, or the original exhausted +heading-search stop when no proxy checkpoint exists; +safe original paths retain their normal random stream. Emitted joints are +checked again after plan transforms. This is not a held-object scene-contact +certificate; attachment monitors and existing collision policies remain active. +Factory-owned, adjacent same-object/resource verified yaw-free Align/Place calls +also preview the canonical Place from a private planned endpoint. A qualified +original continuation retains the exact Align plan and random stream. Only a +failed joint continuation searches the original eight headings, with unchanged +targets, timing, limits and retained-command authority. Preview effects never +commit; actual Place still observes, grounds, replans and verifies release. +If that search fails after robot-proxy rejection, explicitly bound native-rigid +alignment occurrences may try two bounded staging detours. Their intermediate +poses preserve the acquired orientation, original staging height and final +goal; the passive arm does not move. Measured distal-mesh projections provide +only route hints. The shared planner rebuilds each complete plan, whose emitted +commands undergo the unchanged robot-proxy, joint-limit, velocity and retained +grasp checks, including the observed first command and post-transform boundary. +An unchanged, already-applied grasp target is command continuity rather than +new finger motion only when the adjacent verified attachment contract and fresh +native target position/velocity prove it; changed or unavailable targets still +fail the original boundary checks. This does not certify contact force. +Extra detours preserve the legacy-stop RNG state. Other calls and safe original +plans do not acquire this recovery implicitly. +Unrelated `DrawerRoute` declarations cannot clear explicitly verified ordinary +staging authority. Owned drawer transports still opt out through their actual +invocation-local direct-transport scope and retain their payload-aware route. +Mixed-route authority changes invalidate old integration fingerprints; regenerate +new bundles rather than resealing historical ones. This is an authorization +boundary, not full articulated-world or continuous-collision qualification. +Generated released-hand cleanup uses `task_engine/_task_program/clearance_recovery.py`. +An adjacent same-object, same-resource verified Place/clearance followed by one +or two distinct sequential Parks including the owning arm enables its bounded +route search. Both registered releases and curated Place use their actual +effect-monitor binding. Canonical shared-compiler policy grounds each configured +Park from the previous full-robot endpoint. Qualification checks every segment +and boundary in execution order: emitted commands, timing, joint limits, passive +holds, and fresh scene/self/other-arm collision meshes. An observed clearance +start collision stops route search immediately. The shared executor receives +only the accepted cleanup plan; each Park replans and revalidates observed state. +This gate currently supports one environment at index zero and fails closed +outside that scope or when collision evidence is unavailable. Sampled mesh +clearance is not continuous collision or physical-success certification. +Only those factory-bound pure Parks may recover an interior scene collision +using four finite joint vias derived by the existing IK solver. Original ready, +control grid, limits, passive holds and collision exclusions remain unchanged. +Cleanup previews and fresh actual Park planning use the same complete gates; +safe original plans and the caller's random stream remain unchanged. +E5 Robotiq grasp clearance is isolated in +`task_engine/_task_program/coordinated_grasp.py`: only the dual-grasp service +uses URDF collision surfaces and deployment open/grasp commands in TCP space. +Antipodal points seed a bounded finite-pad gap, centering and insertion search; +their separation is not assumed to be the actual contact gap. Watertight target +triangles preserve cavities that coarse convex unions can fill. Both inward pad +faces must reach contact, with the open-to-contact sweep clear of other hand +parts. Non-watertight targets fail explicitly instead of receiving guessed signs. +Near-contact inward-pad samples also require outward target normals within +60 degrees of the corresponding pad-facing direction. This excludes tangential +or back-facing proximity without treating it as force closure. Normal queries +reuse the target triangle BVH and run only on near-contact pad samples; rejected +endpoints do not enter the closing sweep. Two-sided occupancy probes orient +each queried normal using the signed-distance solid convention, not global +mesh volume: independently reversed components and nested cavities retain +their own inside/outside boundary. Ambiguous probes cannot certify contact. +E5 empty-hand acquisition also gives the already-qualified finite candidates +a cargo-clearance preference. Same-context rigid contents are captured only for +that planning call; open/mid/contact hand samples against their signed world AABBs +adjust finite proposal costs with an 8 mm heuristic reserve. No candidate is +removed, no new rejection gate is added, and missing geometry keeps base costs. +This does not certify native collision, contact halos or cargo retention. +Regenerate E5 bundles after changes +to this versioned geometry policy. +Single-arm generator methods and +their factories remain unchanged even in mixed E1/E5 programs; do not tune their +finger envelope or opening margin at program scope. This target-mesh screening +does not certify continuous approach clearance, contact dynamics, or attachment. +`coordinated_motion.py` composes the shared planning helpers for E5 continuation: +two verified grasps of the same object are retained through motion, and hands +open only at release. Missing or conflicting held state cannot fall back to +re-picking. Consecutive E5 relative targets accumulate for terminal checks; +release retreat exceeds the unchanged separation threshold with tracking margin. +`coordinated_evidence.py` observes registered E5 terminal holds separately from +motion execution. It binds both native ATTACH receipts, the authored hold policy +and recorded endpoint poses to the exact compiled occurrence; final holding also +requires fresh native contact for both hands without advancing physics. +`held_evidence.py` owns the shared receipt, pose and grip-query validation used by +E4 and E5. A terminal hold does not qualify in-flight acquisition guards, +continuation, released transport or cargo retention. +E5 `terminal_behavior=place` with `relation=on` retains the bound rigid support +instead of converting it into an initial-pose direction. Bundle generation +reuses E1 relative-placement height geometry; the coordinated lowerer targets +the observed support position while preserving the carried object's observed +orientation. Release clearance is excluded from the resting-position target, +which is checked relative to the support again after cleanup. This uses the +existing E5 position/stability acceptance, not a new contact certificate; mesh +envelope limitations remain. Motion budgets are declared per generated segment +in `constraints.json.motion_samples`, then bound to compiled invocation IDs by +`invocation_policy.py`. The base execution policy is no longer raised by scanning +the whole program. E2/E4/E6, drawer-placement and on-support E5 recipes retain +their staged-motion budgets without changing unrelated calls. The GenSim engine +selects immutable request policies and observes the runner's initial plan; +planning, execution, recovery and state effects remain in the shared engine. +Generated PytorchSolver configurations retain GenSim's 5 mm position tolerance +explicitly, without changing the shared solver's 0.5 mm default. Existing +explicit solver tolerances take precedence; rotation tolerances are unchanged. +Larger caller budgets, control dt and +velocity limits are preserved. Missing/stale bindings require bundle regeneration. +Cartesian sampling is declared alongside budgets in `cartesian_calls`, bound +to compiled invocation IDs, and enabled only within an exception-safe planning +scope. Appending a HandOver, clearance or drawer recipe no longer switches the +whole program's generator. Hardware, initialization, remaining option selectors +and random-state scopes still require separate qualification. +Normal bundle execution writes `planning_probe.json` from the actual first +invocation via `_task_program/planning_probe.py`, without separately planning it +again. Full-robot post-resampling velocity validation still gates that plan +before dispatch; diagnostics distinguish execution evidence from the independent +`--plan-probe-only` mode. The run-local observer matches the exact invocation ID, +restores its scope on exit, and retains no executable plan. Genuine runtime +replans continue to use fresh observations; this is not a cross-run plan cache. +For non-drawer Place, the current `GenSimPlace` planning scope selects the same +Cartesian sampling policy in both checked and approach motion generators. Its +planning and recovery do not depend on unrelated E2/HandOver calls elsewhere +in the program. Outside this scope, each generator's existing policy remains +unchanged; drawer and cuRobo routes retain their own policies. Ordinary Place +paths that previously used joint interpolation may therefore change; regenerate +bundles after the motion-policy revision. For a single environment only, +exhausted Cartesian IK planning may retry through the shared motion generator +with nearby joint seeds and a joint-limit-margin preference. Successful +Cartesian plans do not enter local IK recovery; +the fallback preserves Cartesian samples, control timing and random state, +and rechecks full-robot velocity after Place resampling. GenSim Place retains +v38's scene-dependency guard through approach only; expected contact motion +does not replan release/retract. After that boundary external disturbances +are also ignored by this guard, so final effect and stability checks remain +required. Shared Place retains its full-action guard. This is a bounded +kinematic recovery, not collision or physical-placement qualification. +E6 recovery is bound to exact registered Slide/withdraw invocation IDs, not +all calls of those underlying skills. Bound single-environment `ik_interp` +Slide retains its 85% preshape unless every finite candidate fails aperture. +Only then, measured whole-hand FK selects the smallest sufficient opening in +the 84--75% closure band and rebuilds once with matching Slide options and +call-local clearance. The 4 mm pad reserve, full-hand/table screening and all +execution gates remain; width-fitting/table/IK failures do not widen the hand. +Initial-plan evidence records the selected plan, not the intermediate rejection. +Successful defaults, explicit nondefault preshapes and non-E6 calls are unchanged; +regenerate E6 bundles for the preshape fingerprint revision. +Failed single-environment CPU +`PytorchSolver` / `ik_interp` pull-and-release plans can screen up to four +terminal configurations, solve the contact path backwards, then connect a +free-space joint approach. Slide recovery is capped at 1.5 times the request +and 390 command frames; larger caller budgets are not shortened. Failed E6 +withdrawal first tries local IK without changing its targets or frame budget. +For an adjacent Slide/withdraw pair with identical part/state/resources, +nominal Slide planning and failed-Slide recovery qualify each release posture against +the declared withdrawal sample budget. Every original terminal/cleanup option +has priority over a shorter cleanup. Only after exhausting those options may +an otherwise qualified terminal use a 20 mm rail-outward-only empty-hand route. +Preview and actual withdrawal derive the same finite geometry; both screen +continuous IK, velocity and robot meshes, and the preview +discards the preview path. This is not a predicted-scene certificate: actual +withdrawal is freshly planned and checked against current scene meshes before +dispatch, including when its nominal plan succeeds, only when the lookahead +actually rejected the formerly admissible terminal and selected another one. +The exact adjacent E6 Park after an installed nominal or recovered withdrawal +uses fresh full-scene qualification and may reuse the four Cartesian-via +Park recovery. Interior self/other-arm path collisions may also try those vias, +then at most four limit-clamped neutral interior-joint routes, restoring the +exact canonical Park target. Initial-state collisions remain rejected. Every +candidate retains full scene/self/other-arm, command, limit and velocity checks; +this is not a Native exploration bypass. An unchanged safe home path remains preferred. Its canonical +home target, timing and released-hand requirement remain unchanged; E8/E9 parks +without an adjacent E6 withdrawal are not included. A failed signed push may try +50 mm then 30 mm approach/return offsets, preserving the handle grasp, rail, +joint target and all full-path checks. Pulls and nominal successes are unchanged. +Push diagnostics record the first failed leg instead of only exhaustion. +Unpaired calls retain their existing checks rather than acquiring a blanket +scene gate. Qualification is read from the +paired public ExecutionSession's installed plan attempts, not from speculative +planning side effects. Rejected revisions cannot erase it; a later nominal +replan in that session does not erase earlier installed reselection evidence. +For a push with valid complete contact kinematics/robot meshes whose free +approach collides with the scene, at most two existing cuRobo joint-prefix +proposals may replace that approach. The passive snapshot uses the actual +observed hand, not its future preshape. Prefix endpoints, hand commands, +reach/push/open/return suffix, frame budget and control dt remain unchanged; +longer prefixes reject rather than being accelerated. Shared Slide rebuilds +the commands, then native joint/velocity/full-robot and fresh approach-scene +checks qualify them. This does not bypass collision predictions or certify CCD. +The E6 recovery fingerprint revision 13 owns these changes. Nominal push success +also checks its free approach against the live scene before accepting the paired +withdrawal; a collision enters the same existing bounded recovery, not a second +executor. A valid nominal paired +continuation retains its exact commands; a supported but unqualified nominal +terminal enters the same bounded branch search, without dispatching a preview. +An ordinary rigid lateral Pick/Place pair may reuse goal-conditioned payload +transport only after its cheap preserved-orientation Place fallback reports a +robot self collision. It retains the exact release, contact and return targets; +the existing payload-aware free prefix and emitted collision/velocity checks +must qualify. Pick previews derive payload pose from the projected held context, +not the native object's unmoved pose. This binding has a conditional fingerprint +revision; on/inside, authored-grasp and nonordinary routes do not acquire it. +Within this failure-only lateral recovery, the existing single-row CPU +PytorchSolver search may supply up to four distinct release branches. Each +branch rebuilds and qualifies the entire transport/contact/release/retreat; +other solvers retain one branch, and no endpoint alone certifies the path. +For bound ordinary rigid on-Place, held-object clearance against the exact intended +support owner is deferred to native landing/release observations, not certified as +free space. Support affordances resolve through their bound rigid parent, never +by name parsing. Other scene components, robot self-collision, joint limits and +velocity remain screened. This is not proof of contact or task success. The +existing preserved-orientation recovery and exact release/contact/retract goals +remain; its conditional fingerprint requires regenerating affected on bundles. +Generated ordinary E1 cardinal side placements beside rigid references release +30 mm above the projected tabletop landing instead of the resting evidence +target. XY, world orientation and settled validators remain unchanged; qualified +articulated-link, on/above, diagonal and E2 routes retain their existing heights. +The explicit route vector seals this release height in new bundle identity; +saved bundles and the original collision, release and stability gates are unchanged. +Failed five-stage push/close plans may instead qualify up to four grasp-seeded +branches using the original per-stage targets and frame counts. Backward reach +joins forward push, release and return through continuous IK; only the empty-hand +approach uses joint interpolation. Shared Slide rebuilds every command. Final +full-robot velocity and robot-mesh checks, fresh approach-scene screening and +the existing paired withdrawal preview remain required. Scene screening does +not certify future contact/return geometry or physical closing. Successful +push plans remain unchanged. A rejected widened preshape retains its own +diagnostic failure alongside the original nominal rejection, without changing +which failed plan is returned. +The shared skills still rebuild arm/hand commands and the shared executor +still owns execution. Both routes retain tolerances, restore RNG/planning +scope, validate final full-robot velocity, and require fresh discrete mesh +clearance for the changed free-space motion. This is not continuous collision +or zero non-target-contact certification. Successful Slide plans, other semantic +calls, collision-planner routes and shared Lab defaults remain unchanged. +Recovery needs the GenSim `yourdfpy`/`python-fcl` dependencies; unavailable or +unsupported geometry fails closed. Regenerate E6 bundles for the recovery +fingerprint revision; non-E6 fingerprints are unchanged. +E2 release preserves the observed aligned heading instead of adding another +fixed yaw during descent; an upright instruction does not require that rotation. +Generated E1/E2 deployments, including light E5 compositions, cap only grippers +used by single-arm picks at `max_effort: 0.5` when every picked rigid body and +E5 carrier has an explicitly declared mass of at most 10 g. Qualified E3 +pouring resources use 5 across profiles, including Composition. +The full closing range is retained; smaller existing effort limits are not +increased. Unknown/heavier loads, E5-only programs and other recipe families retain their declared +controls. Qualification is per grasp resource: E6/E8/E9 on the other hand +does not disable the cap; a hand shared with E6/E8 keeps its authored +controls, while empty-hand E9 is compatible only with the qualified E3 cap. +Payload qualification is likewise hand-local. Imported mimic behavior +and shared robot defaults are unchanged. +For an existing, unedited scene, `planning.physical_reference` in the ordinary +Task Engine config explicitly selects a reference bundle's physical components +before initial binding. `workflow.py` pins one `FrozenPhysicalInput` through +SceneAdapter, final inspection and coordinator bundle generation; inspection +measures that selected model under its physical digest, not the original scene. +The selection owns episode limits and rejects additional asset/mass adaptation, +source-transform overrides and reference/output overlap. Existing physical +manifests are verified before import. Original-source visual grounding and +reference-image review are not valid evidence for the selected model and are +disabled in this mode. `selected_physical_input.json` records source/model +differences; selection never certifies original-scene equivalence or historical +success. Without an explicit reference, legacy graph-dependent calibration is +unchanged; this opt-in contract is not default-wide composition isolation. +Selecting a frozen physical model retains the public Auto entry's 100 mm +experimental program placement policy in both post-policies and validators; +it does not silently restore the legacy 50 mm program gate. Physical component +digests and strict TaskSpec evaluation are unchanged. An explicit non-frozen +`runtime_profile=default` retains its legacy policy. +An explicit logical runtime profile may retain its motion timing and acceptance +policy with a frozen physical reference. Material overlays, mass conversion, +asset fitting and robot calibration remain disabled for the pinned model; +output physical components must remain identical. Native Pick exploration is +still forbidden with a physical reference. +Ordinary E1 placement on another object retains its position tolerance and uses +`supported_placement`: scaled local mesh vertices are cached per environment, +then transformed by observed poses for vertical gap and projected support-envelope +checks. It does not impose initial roll or either object's initial up direction. +Both objects must still remain stable for the declared window. `on` additionally +requires native upward contact between the exact object pair supporting the COM, +plus measured release; it does not require whole-silhouette containment. Support +sensors are registered in the environment's physics-substep registry. A sleeping +contact witness survives only unchanged body poses, is invalidated by overflow +or movement, and is cleared for reset environment rows. Final support is measured +again; milestones retain their exact observed boundary receipt. This is not +arbitrary concave/tilted-support or three-dimensional cavity qualification. +Relative side placement binds an articulation body or an explicitly grounded +prismatic `reference_part` to one native `SceneLinkRef`. Geometry includes only +the selected link's collision meshes, in its scaled native frame, never a proxy +or the whole moving articulation envelope. Pick lookahead, Place and stability +read that same live link and world-axis displacement; landing height comes from +the measured tabletop. A preceding Slide therefore does not invalidate a +qualified reference. TaskSpec side acceptance measures the selected link's full +world-axis envelope, tabletop support and exact release evidence. Historical +milestones require the matching post-policy link pose and recorded object pose; +final acceptance observes the current link rather than reusing that receipt. +Regenerate relative-placement bundles to declare qualified link routes. This is not a +swept collision certificate. Articulated `on/above/inside` support still requires +its separate qualified link geometry; spatial references do not authorize +joint manipulation. +Explicit upright, oriented hold and stack constraints retain v38's 10-degree +alignment tolerance. Upright handover-to-stack retains the table restaging, +regrasp, preserve-yaw alignment and released-hand cleanup route rather than +directly stacking from the receiving grasp. +Source pose matrices take precedence over Euler fields. +After UID grounding, independent E1 placement, E2 upright, and E5 +lift-and-return `count`/`all` sets lower to ordered single-object steps; +line layout, E5 terminal hold, other task routes, and a downstream +`step_result` consumer still reject implicit expansion. +E6 `count`/`all` sets retain their qualified synthetic part UIDs through +binding, then expand to ordered Slide/withdraw/Park recipes with a distinct +part binding per step. Cabinet-root sets do not stand in for drawer parts. +Handleless parts explicitly named as button, press, plunger or switch controls +are excluded from the pullable catalog; otherwise one button could invalidate +all drawers in the same asset. A real pull handle retains its part, while other +handleless mechanisms still reject rather than inventing a grasp. +For opening sets, measured world-space handle heights order parts bottom-to-top +within each cabinet. The existing 1 cm spatial tolerance groups same-height +parts, retaining their original lateral order, including horizontal rows and +multi-column layouts. Missing geometry leaves that cabinet's order unchanged. +Explicit separate steps and closing sets are not reordered. This is a default +sequence preference, not a collision-free planning guarantee. +E6 uses each qualified handle's position for automatic arm +preference rather than the shared cabinet center; explicit arms take precedence. +This code-owned geometry stays outside the model prompt and runtime scene config. +The final program segment rechecks the last requested position of every E6 +joint, so later manipulation cannot silently invalidate an earlier drawer. +Repeated open/close commands on one joint retain only its last terminal target. +Regenerate existing E6 bundles to include these terminal checks. +Part inventory exposes a configured initial open/closed endpoint only when +the runtime default zero reset matches an explicitly authored, validated +`gen_sim:closedPosition` endpoint or its opposite endpoint. Missing endpoint +semantics, explicit `init_qpos` vectors (unqualified joint ordering), and +non-endpoint resets remain unknown. This is configuration evidence, not a +settled-state/contact observation; no asset or reset value is changed. +For an unbound existing Gym scene, Task Engine automatically renders the +current GLB assets into UID-labeled overviews, segmentation masks and crops, +then retries grounding with the same LLM transport configured for text binding +in `gen_sim/.env` or the process environment; +`--reference-image` is not this binding input. A deterministic tenth of already +bound scenes receives an audit-only visual spot check. Text and visual binding +share semantic identity rules: descriptive categories are not exact-match labels; +synonyms, translations and supported broad names may identify the same entity, +but explicit modifiers, exact UIDs and counts cannot be relaxed into substitutes. +Model responses include matching support, conflicts and nearby candidate UIDs; +reported conflicts cannot authorize a resolved binding. This evidence is not +new scene state or physical capability. Legacy four-field response replay stays +supported. Genuine missing/ambiguous results are not retried into guesses. +Run-local binding audits retain prompts, schemas, responses and model identity, +including early failures; candidates and source fingerprints survive failed +selection. Visual evidence also records scene revision and image hashes; the +VLM may select only visible inventory UIDs, while native semantic compatibility +remains authoritative. Articulation proxy GLBs do not represent live joint state, +so E6-E9 binding does not use this visual path. Without usable Task Engine LLM +configuration, text-only binding and its existing conflict behavior remain unchanged. +E4 may defer unnamed transfer/receiver arms as `auto`; the planner binds the +source from the held state or nearest scene side and the other arm as receiver, +while preserving explicitly named arms. GenSim declares `pick_purposes` per +generated Pick segment, bound to the compiled runtime invocation identity; +missing or stale declarations reject loading. Built-in Pick identity and +compiler-owned downstream reachability remain unchanged. Ordinary and pour pickup +try top-down before arm-relative diagonal approaches; an infeasible top-down +strategy retains the diagonal fallback. E4 source lowerers try the arm-near end top-down and +diagonally before considering the far end, leaving the other end for reception. +The wrapper marks only an owned goal +snapshot; upright and stack constraints take precedence over ordinary policy. +Constrained rigid Picks resolve their immutable task grasp filter through the +known E6 approach wrapper only when their geometry is not a bound handle. +Lowering, candidate selection and roll/path recovery share this resolution; +unknown providers and handle geometry cannot bypass the E6 policy. The shared +sampler and its rules remain unmodified, and ordinary adaptive Picks retain +their existing provider path. +When every nominal top-down constrained candidate is rejected geometrically, +the same call-local filter may screen the existing arm-relative diagonal +strategy. Shared full-Pick planning still owns the trajectory and effects; +nonempty nominal pools, explicit directions and downstream targets are unchanged. +Owned yaw-free staging in a drawer deployment also screens the operated robot +against live articulation meshes while selecting its existing yaw candidates. +This narrow screen prevents uprighting from pushing a drawer closed; it is not +a carried-payload or ordinary-rigid scene certificate. Non-drawer staging keeps +its original robot-proxy screen. +Drawer routes share geometry per affordance but serialize `upright_calls` for +the exact transport and Place occurrences with an explicit upright alignment +in the same task group. Assembly binds these names to invocation identities; +runtime selects a non-mutating observation view, including recovery within the +same generated one-call segment. A later placement cannot overwrite an earlier +call's policy. Legacy route-wide flags remain readable. Placement varies yaw, not pitch/roll, +and first tries a supported release after crossing the rim rather than a high +drop. The rim retains 25 mm payload clearance without the extra 120 mm legacy +lift. Before payload-aware transport, these routes rank the same finite entry, +release and open-hand endpoint candidates; cuRobo transports in the selected +heading. Place still replans from observed state and checks its complete path. +This is endpoint ranking, not a full future Place replay. Ordinary drawer routes +retain their original release order; new bundles declare an empty call scope. +Explicit E1 `orientation_goal=vertical` means an undirected long axis only +when the user permits either pole. It keeps ordinary acquisition and serializes +`axis_direction_free` on alignment calls and their stability presets. Alignment +selects the nearest vertical pole; runtime and final TaskSpec observers use the +same absolute axis projection. Existing `upright` stays directed toward +Z and +does not inherit this relaxation; mouth-up and base-down intent remain directed. +An untouched E1 source already within ten degrees of directed upright keeps +ordinary acquisition rather than the inversion-specific grasp-region filter; +its generated alignment and upright acceptance remain required. Occupied +upright drawer landings reuse the existing planar-container selector with the +observed contained payloads. Center and two side preferences stay bounded, and +release heights 0/25/50/120 mm are ranked before spending at most two full Place +plans. Empty drawers and ordinary non-upright routes retain their old policies. +`GenSimPickUp` screens each +candidate strategy through the shared full pickup planner and retains the exact +successful trajectory per row; endpoint IK alone is not acceptance. Explicit +grasp poses and fixed grasps retain their contracts. A failed constrained, +single-environment Cartesian Pick without downstream look-ahead may try one +symmetric roll in the calibrated grasp frame. The original opening, region and +release-clearance filters gate that alternative; the shared Pick planner rebuilds +its trajectory and proposed attachment together. Full-robot velocity and arm +joint limits gate the final resampled path. Successful original plans and later +calls' random streams remain unchanged; exhaustion retains the original failure. +Its direction prefilter removes only candidate columns whose two roll variants +are rejected in every environment, then delegates to shared `PickUp` and restores +the original candidate indices. Upright adjustment and unconstrained approaches +delegate unchanged. Keep the full environment axis; do not copy the IK loop or +change shared defaults to optimize this GenSim selection. +`GenSimHandOver` chooses the receiving end from the actual source attachment. +Vertical receiving grasps try diagonal then top-down; horizontal ones reverse +that order. Candidate, IK or path failure triggers one alternate-direction +attempt through the complete shared HandOver planner before execution. Successful +rows retain their first trajectories and attachment candidates. Exhaustion +fails normally; this planning retry adds no source regrasp or cross-call recovery. +Generated E4 deployments qualify the receiver hand's emitted joint-command +grid in the supported single-environment Default scope against invocation-owned, +enabled native non-target collision shapes through +`handover_safety.py`. Materialized geometry owns its effective scale; do not +reapply an asset YAML scale that USD preservation may have replaced. Safe +trajectories, effects and timing are retained; full-plan failure may use only the +existing alternate receiving direction. Deterministic (`affordance_sampling=None`) receiving +selection first filters that same candidate pool with the original Cartesian +approach grid and bound-open native hand geometry, without extra candidates, +IK calls or random draws. Candidate costs and ordering remain unchanged; the +final emitted-command check is still required. If that original pool is exhausted +only by scene geometry, `handover_exchange.py` may select an internal exchange +position from bounded, native-geometry-derived displacements in the root middle +plane. It preserves the original relative grasps and candidate costs, uses the +configured IK and joint limits, restores random state, and does not change the +semantic task target or physics. The shared existing-hold receive hook returns +the exchange pose with its grasp sample, so source transport and the destination +attachment use the same pose. Safe original pools do not enter this selection. +Nominal candidate screening is +not a certificate for an IK solution or physical acquisition, and stochastic +branch sampling retains its existing selection plus the final command check. +This discrete hand/environment check does not +certify target contact, robot self-collision, payload clearance, future scene +motion or between-sample clearance. Its E4-only revision is fingerprinted; +regenerate changed E4 bundles instead of resealing historical artifacts. +Transfer, release, retreat and state effects remain owned by shared HandOver. +Only derived adaptive handover ends may select the GenSim-owned +`_task_program/supported_end.py` provider policy. An already viable mesh-end pool retains its poses, +costs and random draws unchanged. If that geometry pool is empty before IK, +the same prepared pairs and approach variants may define an end from the +angle/NMS/static-qualified support, before ranking truncation. Explicit +top/bottom or hard task regions remain `mesh_extent`; IK, path and physical +acquisition failures never activate this reinterpretation. GraspKit owns +qualification and ranking; its Antipodal `pg_grasp.GraspRegionSelector` extension passes +only qualified rows to the GenSim strategy before top-K. The provider does not +copy the backend, mutate its cache, or create a second sampler. The adapter +contract requires regeneration when this policy boundary changes. +Generated integrations with HandOver or curated Place include the curated Pick +monitor needed by existing bounded workflow recovery, even when source +acquisition uses only a registered alias. +This does not change recovery budgets or qualify initial grasp stability; +regenerate bundles to acquire the declaration rather than resealing old files. +GenSimHandOver retains the bound closing drive through the shared hand-target +hook during existing-hold transfers. This is an application strategy, not a +shared HandOver option; old `source_hold_mode` declarations are rejected rather +than silently ignored. Missing retreat budgets retain the GenSim default, while +shared composition keeps its own defaults. See +[Atomic Action execution](../atomic-actions/execution.md) for the hook boundary. +E5 paired grasping and E6 handle policies remain separate. These GenSim-local +skill replacements use the shared goals and options. Unmarked calls +delegate unchanged; drawer deployments install the same ordinary wrappers. +Constrained E2 Pick lowerers +snapshot their object/target rule selector into the goal; only that Pick uses +an immutable filtered-generator view. Unscoped sampling, including HandOver, +checks opening clearance without applying another stage's region/release rules. +Drawer transport and release remain drawer-owned. Ordinary drawer release first +uses the existing rim route without the extra 120 mm release lift; that higher +release remains the fallback. Outside/rim poses and the payload floor target +are unchanged. Both modes share the original two-full-plan budget, final velocity gate, +physical release and containment checks. A conditional drawer release revision +requires regenerating affected bundles; this is not permission to ignore walls +or close around an uncontained payload. Relative placement geometry and +stability use preceding alignment operations, never future E2 state. E2 after +an explicit on/above placement retains that support and uses its measured top +for staging, release and grasp clearance. Its constrained regrasp uses a +top-down approach so uprighting yields a side grasp instead of an end-directed +rim approach. Standalone E2 retains its original table target and grasp policy. +The GenSim-owned `gen_sim.place_upright` call reuses Place while +separating the later upright release geometry from the earlier ordinary Place +route. Repeated occurrences retain stage selectors; conflicting geometry for +the same stage is rejected rather than overwriting its route. An implicit +singleton retains the v38 declaration shape, while an authored selector is +preserved even for a singleton. +Terminal preserve-pose handovers verify receiver attachment and the +declared world-axis alignment. A preceding upright stage makes that axis +world Z instead of reusing the initial fallen orientation. +`handover_evidence.py` connects exact native TRANSFER receipts to E4 TaskSpec +events, separately from terminal receiver holding and orientation observations. +Authored hold policies retain their existing duration and attachment/axis checks; +an undeclared hold window is not added. Historical milestones use their own +recorded boundary, while final holding also checks fresh receiver-relative pose. +Missing receipts or unsupported later execution remain unavailable, not inferred +from command completion. This changes observation, not HandOver execution. +E4 `place` outcomes with rigid `on`/`inside` targets also collect exact receiver +release and placement evidence, separately from the earlier native TRANSFER +milestone. Observer revision 7 records those two boundaries in execution order; +final geometry cannot fill a missing transfer or historical placement. Explicit +support revision 1 applies the same native support contract to these E4 placements +without weakening legacy E1 or terminal E4-hold behavior. +`task_engine/_task_program/identity.py` hashes complete validated registration +declarations for both generation and verification. Adapter v14 removes the +historical default-field projection; older executable bundles require explicit +regeneration, without rewriting old files or accepting hash aliases. Physical +reference inputs remain separately supported. Shared registration drift checks, +program and constraint identities remain mandatory; do not extend the shared +Pick/AxisAlign schema to bypass those checks. +Multiple children +placed inside the same measured container reserve each prior landing footprint +and margin; insufficient space or an unmeasured shared floor fails preflight +instead of assigning overlapping destinations. Each landing uses only declared +orientations preceding its own Place; a reservation retains its placement-time +orientation rather than a later alignment target. This is a planning snapshot, +not a live occupancy tracker or physical placement acceptance. +Ordinary E1 `on` routes sharing one stationary rigid support also reserve the +projected footprints of preceding releases. Only an overlapping later endpoint +is relocated on that same support with the existing 20 mm separation; re-picking +an object frees its reservation. Single-object, moved-support, articulated and +explicit spatial-reference routes retain their prior targets. These source-mesh +proposals do not replace runtime collision, release or support qualification. +Stationary eligibility excludes any support named as a manipulated object in +the program, including HandOver and registered coordinated hold/transport, not +only ordinary Pick. Loading a later-carried vessel therefore does not acquire +flat-surface packing constraints merely by splitting E4-place into E4-hold/E1. +Later lateral placement relative to a prior rigid-inside release uses that +stationary container's measured source floor to project the anchor height, +rather than its pre-transfer height. Re-picking invalidates the projection; +moved containers, articulated/tilted or unmeasured floors and aligned anchors +retain their existing route. This is a preparation-time target projection, +not a physical release receipt or a change to runtime placement acceptance. +The contact experiment also grants native revision-8 closing/depth checks to an +unconstrained horizontal rigid Pick immediately followed by an ordinary on-Place +with the same object and arm, when source geometry has a 3:1 long-axis aspect +ratio. Explicit grasps, upright sources, Pour, inside and other profiles retain +their prior declarations. This reuses the existing bounded native search and +does not relax measured acquisition or retention. +For untouched height-dominant rigid sources in unconstrained ordinary inside +recipes, the contact profile selects native closing revision 9. It retains +revision 8's source, opening, depth and scene screens and additionally bounds +the native collision-pad center line to two degrees from the gravity plane +through the first nominal bilateral contact. Gravity is captured in the current +object frame; emitted closing commands use the same check. Other profiles, +authored grasps, previously moved sources, upright-result revision 2 and confined +measured-preshape routes retain their existing policies. This discrete quality +condition is not evidence of real acquisition, retention or placement success. +Generated non-drawer held-object transports declare a measured attachment postcondition. +GenSim installs PickUp, HandOver, MoveHeldObject, Place and Pour wrappers for all +deployments after shared engine validation and configure shared Lab action +options through the skill profile. The transport wrapper stages above the target and +returns the input attachment as its expected effect, so the existing composite +monitor verifies retention before observed-transform reconciliation. This is +terminal verification, not in-flight slip prevention. Regenerate older bundles +to include the wrapper registration and revised lowerer fingerprint. +E3 now uses the vessel's geometric upright axis only as an upright reference, +not as its rotation axis. The selected grasp is checked at runtime against the +actual pad line before the tilt arc is generated; +The GenSim Pour wrapper reads the two native finger-pad link poses (not TCP-X) +and derives the projected pad-line as its rotation axis. Its visible object +tilt is the cross product with upright, hence perpendicular to the actual jaw +line. It samples the full tilt-and-return arc through the shared motion +generator. +No spout annotation is required for this tilt-and-restore contract. Receiving +vessel identity is bound per Pour invocation from that recipe's explicit staging +reference, not from an object-wide map. Its position is late-bound while the source's upright heading is preserved +independently of receiver yaw. Rim height, vessel radius and the declared finger +envelope bound the clearance; E3 transports stage above the target before +descending. New bundles bind 0.12 m retreat/approach height only to each E3 +post-Pour return Place invocation; ordinary Place keeps 0.05 m. Legacy bundles +without that declaration retain their original profile options. Release +acceptance is unchanged. This is geometric/kinematic screening, not global collision planning +or proof of fluid transfer; ambiguous upright geometry still needs qualification. +For level containers with a dominant planar floor, inside placement selects an +arm-side point from the actual floor triangles, eroded by the projected child +footprint and a margin. Holes are retained. Unsupported floor geometry retains +the existing target policy; an oversized footprint on a measured floor fails +explicitly. This geometric preference still requires downstream IK and physical +release/containment qualification. +Opt-in grasp fitting reserves the declared/default robot and object contact +envelopes before selecting a uniform scale. The adaptation report records the +effective per-jaw clearance; the 0.25 minimum scale and source-preservation +boundary remain unchanged. + +`task_engine/ontology.py` owns scene-independent task meaning and capability +requirements; `task_engine/interpretation.py` owns strict intent validation and +model guidance. E6 is a prismatic part opened or closed (`target_state=open` or +`closed`, `slideable`); E7 is a revolute door opened (`target_state=open`, +`openable`). Closing a drawer remains E6 regardless of the selected arm. +Closing a hinged door is not represented by either contract. + +`task_engine/agent.py` derives SceneRequest requirements from that ontology; +`task_engine/orchestration/scene_adapter.py` checks declared capabilities without +aliasing legacy `pullable`/`pushable` labels. Empty capability metadata remains +unknown, not proof of native joint type. Native joint qualification is deferred +until execution integration. + +Persisted candidates must match the current intent and exactly derived scene +request. Regenerate legacy E7 closing candidates and E6/E7 candidates with old +capability declarations; do not silently relabel them. The serialized field +layout is unchanged. Execution admits serial compositions of E1-E6 and calibrated E8/E9; +E7 remains rejected before graph generation and bundle publication. E6 uses the explicit registered +Slide/withdraw/Park recipe in `_task_program/articulation_binding.py` and +`articulation_slide.py`. Its first supported binding is one fixed-base, +single-prismatic, self-contained metre-authored USD with uniform scale and an +unambiguous handle mesh, in one simulation environment. Asset hashes, joint +ownership, and declared limits are checked again at runtime. Public Slide owns +planning; public Task Program and Gym own execution. Joint-target retention is +checked after every recipe call; this is not in-flight contact qualification. + +E8 is owned by `_task_program/twist_binding.py` and `twist_runtime.py`: a source-qualified +revolute knob lowers to prepare/bounded Twist chunks/Park through the public `Twist` skill and +ordinary Gym runtime. Legacy chunks are capped at 5 degrees and the next semantic segment reads +the measured qpos again. An explicit optional E8 `twist_goal_mode=coarse` uses +`target_setting=0` only as an intent placeholder, not as printed label zero. +The planner chooses the farthest nonzero source-calibrated setting that fits the +existing recipe budget, leaving contact-travel headroom rather than capping motion +at a near-zero printed mark. This is only a motion reference; that label is not +added to the normative coarse task goal. Explicit coarse routes use bounded +20-degree commands; legacy routes retain their prior span. +All chunks must retain one consistent reference, and ordinary source/runtime +qualification plus native coarse contact-travel/release acceptance still apply. +Legacy steps without this field retain exact setting lookup and recipe behavior; +an unavailable requested label is not silently replaced. +Nonzero references reserve 32 feedback calls; nominal 5-degree coverage +plus the bounded candidate recovery must fit that bound. Verified coarse contact travel permits +unused calls to become one-frame holds; Park still checks release and clearance. The printed setting uses +pointer/label geometry and an asset hash; ordinal settings and joint-limit guesses are rejected. +`twist_semantics.py` resolves asset-owned joint/grip/pointer/label roles through the +[twist source semantics contract](twist-source-semantics.md), not a source-SHA allowlist or +mesh-name heuristics. Source and normalized semantics identities remain separate integrity +checks. Missing semantics are unavailable, while stale or conflicting declarations fail +closed. This supports unseen annotated assets, not visual recognition of arbitrary unlabeled +knobs; hash integrity alone does not supply printed-label semantics. +`twist_adaptation.py` screens source-qualified geometry against the active gripper: compatible +dimensions remain unchanged; mismatches propose a uniform assembly scale with preferred 10 mm +grip depth. The preference is clamped to the uniformly scaled depth/opening feasible interval; +an empty interval still rejects rather than bypassing physical dimensional limits. +The canonical minimum depth is empirically qualified, not inferred from opening-axis +finger thickness. Dimensional candidates still require actual physics acceptance. Audited XY +relayout moves only unreferenced rigid `on(table)` children, +excluding supports/parents. Four axis-separation candidates reuse Scene Engine's 20 mm target +margin and check table bounds and other AABBs; this is not its full layout optimizer. +When source dimensions are retained, a source graph's direct rigid `on`/`inside` +payload can keep an inherited whole-assembly AABB overlap. The adaptation audit +marks that coarse screen as deferred to native physics, not a collision-free +certificate. Undeclared/new overlaps and resized assemblies retain rejection. +The formal generator proposes 1 mm total extra lift after preserving the resized support bottom. +`twist_support.py` checks full swept geometry; `twist_attempts.py` rebuilds from the original +PreparedScene at 2/3/4 mm only after support-related startup rejection. Geometric penetration also +gets bounded preflight alternatives. Source USD, mass, drives and contact envelopes remain unchanged; +after verified startup/mass readback, typed table-screen rejection or exhausted zero-contact +candidates may trigger the finite grip-depth search owned by `twist_attempts.py`. Every candidate +is rebuilt from the original PreparedScene; scale and lift never accumulate across attempts. +Other failures, resource stops and unqualified observations do not authorize dimension retries. +E8 retains source scalar mass while converting COM/inertia to the scaled actor +frame before Default materialization, not through runtime native writes. `twist_mass.py` verifies +the source-bound native mass, local COM and full body-frame inertia at sensor configuration, +including the SDK's bounded near-diagonal numerical conversion. When the Lab loader exposes +`body_scale_mass_policy`, the compatibility path may select its USD `fixed_mass` conversion. +Otherwise bundle generation automatically uses GenSim's `twist_mass_source.py`; the planning +field `twist_mass_source` can also explicitly select this path. It generates a self-contained +deployment USD that only scales authored COM and principal inertia, retaining a pristine +source copy, sealed roles and a separately pinned mass-lineage manifest. The deployment removes +the Lab mass-policy field, so the pristine asset is not edited and conversion is not repeated +by Lab. Default-only qualification compares the complete authored layer and rejects external +asset-valued dependencies. Native readback still uses the pristine source and existing +tolerances; the deployment conversion is not guaranteed bitwise equivalent to the compatibility +path. Mass ownership does not change feedback or execution ownership. A raw or repeated scale fails +closed rather than applying another runtime correction. Verified pristine mass +lineage preserves geometric E6 part IDs when E8 and E6 share an asset; E6 bindings +still seal the runtime USD hash and invalid lineage rejects. E8 owns source mass +for that shared asset, so E6 does not also impose its ordinary 1 kg moving-link +calibration. The adaptation audit +separates actual gap from conservative contact-envelope reference. Direct helper calls retain +their conservative default. Canonical startup evidence covers sensor-observed Prepare substeps, +not direct World updates during reset/settling; its `complete` flag means the observation window +was finalized, not that every reset physics step was captured. Invalid/overflowed +observations, motion or table/robot contact fail closed. Final E8 coarse acceptance requires at +least 15 degrees of debounced absolute travel during target contact, release and stability; +Park rechecks all conditions. The 0.5-degree anchor deadband excludes small oscillations, +and contact loss resets the anchor so uncontacted motion cannot earn credit. +Target-setting error and signed directional travel remain diagnostics, not success gates. +Parent contact is recorded as a warning, while released contact and conservative +40 mm world collision-input AABB separation after Park remain required. `twist_geometry.py` +owns source-hash-bound USD collider inputs and URDF finger colliders. Mesh transforms are +baked into each owning link frame before deployment scale is applied exactly once; +observed native rigid poses are not scaled again. Candidate contact proximity uses only +the calibrated grip collider, not the full render-link union. Parent screening and Park +use owned collider inputs, including non-selected articulation bodies. Default render +vertices are not collision inputs. Authored convex-cooking policies remain diagnostic; +these proxies do not certify backend cooked shapes or continuous collision clearance. +Robot table and rotor-sweep guards consume conservative envelopes of every finite +authored collision vertex, not triangle surfaces. Their vertex-only URDF loading +retains points belonging to zero-area STL facets and returns no surface-topology +claim; indices and finiteness remain validated. Knob USD geometry and default +URDF surface consumers retain strict triangle validation. Regenerate E8 bundles +for revision 19; no table margin or native contact criterion is relaxed. +E8 lowering allows four native-dtype roundoff units at calibrated joint bounds +for USD/native conversion and constraint projection, then bounds only its +planning scalar. Geometry freshness and recorded evidence retain the raw native +observation; substantive overtravel and nonfinite values remain rejected. +Candidates use final tip bites +B/3, 2B/3 and B, where B=min(grasp_depth, grip_depth/2). Their TCP shifts are outward-only, +so no extra inward offset can exceed the requested bite. Depth takes precedence over closed-hand, +arena-frame geometry scores. The shallowest feasible layer selects the original first roll. +Zero-contact recovery retains the same-roll depth order and its dimensional-retry receipt. +Later contact loss may unlock a previously productive grasp only after measured release +and control-tick stability; this schedules a bounded unused candidate, not turn completion. +Two consecutive contact chunks without new debounced travel may instead choose a shallow +qualified candidate on another parallel-gripper axis, only after measured release and +control-tick joint stability. Axes are equivalent modulo pi, and an explicit fixed roll +never permits other directions. First grasp plus both recovery kinds share three attempts +total; no candidate is reserved twice. Each new candidate is replanned and screened from +fresh observations. Continued productive contact and completed goals retain their candidate. Exhaustion is an +explicit failure, not more sampling or relaxed acceptance. Failed IK cannot +silently fall back to an undeclared base pose. The lowerer measures matching jaw aperture and uses invocation-owned typed grasp +overrides; public `Twist` and non-E8 routes remain unchanged. +Reaching the coarse contact threshold makes remaining Twist calls stationary holds; it does +not skip final release/clearance checks or imply precise arrival at the printed setting. +An opted-in feedback controller still records those successful guarded stationary calls; +they require no correction but cannot be mistaken for unowned/missing plans. +Completed holds and waits retain the issued joint target instead of re-anchoring to measured +gravity sag; dynamic-goal and velocity checks remain active. +The E8 factory borrows its existing acceptance sensor for an instance-owned +`twist_geometry_guard.py`. Before ranking, successful candidates must clear the actual +native table bounds plus measured contact offsets across all command waypoints in +approach/reach/retract, covering the active arm and hand source collision inputs. +Unsupported snapshots fail closed; source meshes and paths remain bound to their hashes. +This discrete source-input screen is not continuous clearance or actual servo-tracking proof. +Finalized plans may monitor the fixed root parent instead of the rotating child only when +source shell topology, native hinge/current qpos, public grasp invariance and every extra +rotor collider's swept-envelope separation qualify. Complete convex projection can prove +separation where a conservative AABB cannot; unresolved qualification retains the original +child dependency. Commands, trajectories, recovery/tracking policies and the reach cutoff +are unchanged, and merged dependency cutoffs cannot shorten an existing monitor window. +The public Twist and non-E8 registrations do not construct this guard. +The qualified zero-contact retry may explicitly enable route-owned `twist_feedback.py`; +ordinary compatible routes leave the controller absent. `GenSimActionEngine.start` selects +GenSim's `TwistFeedbackSession` only for the opted-in single-environment, effectless, +empty-hand Twist call. It extends the public `ExecutionSession.tick` and `revise_current` +boundary while retaining the original Runner, SemanticCallExecutor, Gym bridge and transports. +The public phase view supplies scheduling identity only, not a held-object assertion. +Native observations remain measured; continuation seeds require matching native command-target +readback, and replacements retain the original logical/wall deadlines. Correlated effect, +gate or held-guard results fail closed rather than entering a revised plan with stale identity. +`twist_continuation.py` plans only a bounded local suffix, screened through the same geometry +guard before installation. Its joint angle comes from the same-timestamp live SceneSnapshot, +not TaskState's verified symbolic joint accessor or a lowering-time geometry measurement. +E8 revision 16 passes the configured twist waypoint count to the shared segment allocator; +insufficient sample budgets fail before IK without retiming or extending deadlines. +Opted-in initial approach/reach retain endpoint alignment holds before checking native feedback; +the holds consume the original deadline and undergo the final velocity/geometry checks. +Closure uses one paired aperture/tip-offset calculation; no native +pose or physical-property setter supplies success. Adaptive closure and convex-cooking +experiments remain unintegrated; this opt-in does not certify dual-pad grasp or printed-setting +convergence. Grasp-axis recovery discards only the old grasp bias and recent correction +samples; pending revisions prohibit switching. Episode counters, per-call deadlines and +audit history remain intact rather than using the episode reset method. +The adapter identity uses the complete current declarations described above. +Non-control routes retain their behavior. E8/E9 support multiple serial +occurrences, including repeat operations on one object and interleaved E1-E6 steps. +Each occurrence owns its call alias, sensor, post-policy presets, candidate/feedback state +and sampling epoch. Startup observes its own stable, in-limit initial angle, not a forced zero. +Control post-policies stamp the exact route/source identity and sample window at the +terminal segment. TaskSpec goals and milestones consume those measured receipts through +the canonical runner. E8 coarse contact travel is the selected formal success criterion; +the requested setting and actual target error remain diagnostics, not false joint-near evidence. +Its normative predicate is a semantic event, with a route-owned strict-setting criterion +interface. Repeated events never borrow another occurrence's evidence. +`twist_evidence.json` records measured qpos/contact evidence. `no_twist` and `centroid` are +negative/diagnostic variants only; source assets and shared robot defaults remain unchanged. +E8 alone has a bounded episode-step cap. `orchestration/execution_resources.py` serializes ordinary +E8 subprocesses and monitors available RAM; resource stops retain receipts and cannot be accepted +as task success. E8/E9 use the shared full-episode audience recorder; no control-specific +close-up camera or recorder override is installed. + +E9 is owned by `_task_program/press_binding.py` and `press_runtime.py`: an +explicitly bound, fixed-root prismatic button lowers to prepare/Press/Park +through the ordinary Task Program and Gym runtime. Generated deployments audit +scaled limits, pre-resize calibrated moving-link mass and an explicit release bias; +source USD and shared physics defaults remain unchanged. No synthetic latch is +inferred from a STOP label; the sensor never commands the button. Grasp TCP is offset to +the closed fingers' leading geometry. Mandatory post-policies verify released +stability, at least 0.05 mm continuous contact-backed travel and 40 mm axial +finger withdrawal. Park requires that episode's verified withdrawal, released +button/housing contact, and 40 mm world mesh-AABB separation between every +finger and target articulation link, not the same axial half-space. This is a +conservative geometric bound, not exact collision-mesh distance. Post-Press/Park +holds retain the native terminal command target so withdrawal can finish +converging; preparation instead holds the observed released pose. +Rebound does not erase the event; full mechanical +travel, device activation and self-latching are not claimed. New standalone and +mixed E8/E9 programs use the same authored verified execution policy. Empty +effect plans project no state claim and need no effect monitor; physical truth +still belongs to the mandatory contact/release/withdrawal post-policies, which +cannot be removed. Adding an unrelated E no longer selects a projected policy. +One environment and unambiguous source-qualified controls are supported. Multiple serial +press events, mixed recipes and repeat objects retain independent contact/release receipts. +The old standalone press probe was removed; qualification uses +the normal Task Engine route. Regenerate E9 bundles after lowerer revisions. +For one environment, a failed Press phase may reuse the bounded previous-waypoint +IK resolver with the same Cartesian targets and requested control period. +Successful nominal phases are unchanged. Shared control-grid retiming and final +full-arm/hand velocity checks still apply; a kinematic recovery is not contact +or collision evidence, and native press/release/withdrawal acceptance remains. +If the complete nominal Press still fails, a single quarter-turn wrist-roll +alternative retains the calibrated contact point, forward axis and resource. +The same Press planner builds every phase again, capped at two complete plans +including the nominal one. This is failure-only; successful nominal plans and +explicit custom affordance subclasses do not acquire this alternative. +E9 preserves the declared/native button, housing and finger contact envelopes; +it does not override contact or rest offsets. Normal E9 generation sets only +the selected button assembly to unit body scale, preserving XY, rotation and +the original support bottom. When E8 and E9 share an articulation, E8 alone owns +its scale/support adaptation and both controls rebind to that geometry. E9 accepts +the derived mass source only with E8's pinned, fully revalidated source lineage, +original/runtime hashes and deployment scale. It then calibrates drives against +the fixed source mass without a second mass/inertia overlay. Independent E9 +controls retain their original scaled-mass calibration. Other objects and source USD remain unchanged. +Table-footprint or object-AABB conflicts reject the deployment. The audit in +press_adaptation.json records original and deployed geometry; mass and release +drive retain their pre-resize calibration. This explicit deployment policy is +not gripper-driven size estimation or proof of original-scene success. +E9 physical configuration identity hashes resource contents rather than their +absolute locations, so nested transaction publication and final-bundle copies +preserve identity without allowing physical-parameter or asset-content drift. +An explicit E9 route may declare 0--10 mm extra commanded press travel. +`planning.press_extra_distance` exposes this as a request-owned override, +fingerprinted in the generated E9 lowerer routes. Explicit zero keeps only the +native button stroke; omission preserves the legacy 10 mm extra travel. The CLI +records and forwards zero without changing other requests, source limits, drives, +contact/release observations or withdrawal acceptance. This changes only public Press's +command distance, not button limits, target state, physics or acceptance. The +extra distance is included in the route fingerprint; the bound is not a +collision-clearance or hardware-safety certificate. + +`task_engine/scene/articulation_geometry.py` measures Z-up, metre-authored USD +collision meshes in the native base-link frame, not the default prim's world +frame that runtime reset replaces. Final inspection now measures articulated +geometry. E6 rejects an unmeasured tabletop, more than 2 mm initial table +penetration, or a buried handle before bundle publication and at runtime binding. +An explicit proxy-fit repair returns a new configuration using uniform scale and +a 1 mm placement clearance, levelling only bases within one degree while preserving +yaw; normal loading never silently applies that repair. +Publish repaired exports separately with asset provenance. GenSim assembly and +E6 binding check fresh native joint limits and reapply the same values only when the +public pre-scale cache is stale; it does not enlarge the physical travel range. +Generated E6 bundles apply the calibrated 1 kg mass only to discovered +prismatic moving links. Fixed cabinet/root links retain source-authored mass, +while contact offsets and materials remain asset-owned; this preserves the +Slide grasp response across the legacy loader and Spawn without restoring the +old global articulation-physics override. +For an asset shared by E6 and E9, existing explicit button target modes and +calibrated gains remain intact. Passive drawer defaults are merged by joint; +the generator must not add a global disabled drive alongside active button modes. +Authored drive types, matching target-mode rules and friction remain authoritative. + +E6-open / E1-inside / E6-close composition is owned by +`_task_program/drawer_binding.py`, `drawer_geometry.py`, `drawer_runtime.py`, +and `drawer_curobo.py`. +When drawer routes exist, the adapter creates `DrawerPlacementEngine` but keeps +ordinary wrapper installation unchanged. Explicit drawer planning scopes delegate +transport and Place to the original primitives. The `gen_sim.drawer_transport` +semantic call reuses MoveHeldObject with the effectless drawer contract; ordinary +`simulation.move_held_object` calls retain attachment verification even in the +same program. Drawer motion and later Place/E6 acceptance are not a new transport +retention certificate. Adapter contract v8 requires regenerated bundles with +invocation policies and distinct drawer routing. +Inside targets share E6's asset-qualified part/link identity, never a duplicate +rigid root. Geometry supplies a floor/center hint, not an interior certificate. +The GenSim adapter refreshes the placement target from actual link/object poses +on every Place plan/replan while preserving the declared scene manifest. +No cavity-fit or separate FCL rejection gate is installed. A Pick with an explicit +downstream drawer target defers that reachability screen; a later drawer task on +the same object does not disable ordinary Pick lookahead. Generated bundles insert an +explicit `gen_sim.drawer_transport` before Place: cuRobo plans that free-space +transport, while E6, pickup and final lowering/release retain their existing +planner. The task-owned transport service snapshots live rigid objects and all +articulation links for each plan/replan. Articulated collision components become +separate link-local boxes, preserving openings; the held object is removed only +from the planner world and represented by a conservative sphere cover on a +separate tool-attached collision link. This never attaches objects in physics. +The planner and its payload attachment are released after each planning scope. +This scoped snapshot does not implement concurrent moving-obstacle prediction +or add self-collision checking to the shared cuRobo backend. +Place is planned from the acquired grasp. Composite bundles use the extended +motion sample budget rather than raising joint velocity limits. Ordinary command +planning, effect verification and E6 joint-state acceptance remain. +Execution completion does not prove an object is contained. +Evaluate actual placement/closing from the recorded physical outcome. +Drawer target generation retains its 5 mm lateral planning inset. The pre-close +full-payload check instead uses the measured lateral cavity bounds: a settled +payload need not retain that extra planning inset. Real boundary overflow still +rejects; the existing floor tolerance, upper clearance and complete close-motion +checks remain unchanged.

Built-in HandOver retains its receiver acquisition gate +and source/destination guards. A failed terminal effect or post-policy still +blocks later calls; this does not prove interruption during the current call. + +SemanticLowering has no field for a registered phase gate or held guard. +Registered lowerers cannot replace curated semantics or return skill options; +InvokeCfg has no per-call policy selection. Task Engine must not fill this gap +by replacing the compiler, runner, Session or Bridge, modifying private +invocation state, or treating a terminal stability check as an in-flight guard. + +Retaining built-in calls where their declared inputs suffice is preferable, +but there is no built-in coordinated E5 call.

Its first gen_sim.pick.step_01 plan had +320 filtered grasp proposals but no feasible pre-grasp candidate. A replan +then triggered the tracking-continuity ValueError. The public workflow recorded +semantic_call_failed, deactivated the row and did not run later calls. +The raw report is retained at +outputs/gen_sim/task2_1/20260906_180545/attempts/scene_0001/action_attempts/action_0001/execution_report.json. +The audit wrapper's generic error about a successful single attempt also covers +nonzero CLI exit codes; it must not be interpreted as evidence of a retry here. + +## Grasp Binding Port + +The baseline GraspGoal accepts an explicit grasp pose.

Its factory only selects provider instances and + returns the exact public `TaskProgramEnvironmentAdapter`. +- `grasp_filter.py` wraps the existing parallel-jaw sampling service. Immutable + geometry rules filter unrestricted single-arm proposals by object-local + region and release clearance. Stock PickUp still chooses symmetric variants, + solves candidate IK, builds trajectories, and publishes measured effects. +- `stability.py` implements `SegmentPostPolicyPort`. It observes object poses + and object-to-endpoint drift while yielding ordinary target-qpos holds. + Only Gym consumes those commands and advances simulation. +- `align_held.py` binds a declared object axis using the latest scene + observation. It emits a normal `MoveHeldObject` goal with a minimal rotation; + it neither solves IK nor overwrites the runtime's measured grasp state. + The explicit `current_object_pose` selector changes orientation without + moving the object to a nominal scene position. E1 upright placement reuses + E2's constrained acquisition and staging recipe. E4 upright transfer aligns + on the source arm before HandOver and corrects on the receiver afterward. +- `stack_place.py` registers a separate stack-placement call and option preset. + It reuses the original Place goal/effect binding but does not inherit the low + table-placement TCP cap, which could otherwise eliminate the release retreat. +- `release_clearance.py` binds generated staging heights and a fingerprinted + withdrawal distance to the existing `MoveEndEffector` skill. The free hand + first clears vertically, then moves toward its own arm root before Park. + It refuses a live held attachment and never solves IK or applies commands. +- `motion.py` supplies a planning policy for multi-waypoint EEF approaches. + Cartesian samples are solved by the original motion generator; command + timing, execution, cancellation and recovery remain owned by the core. +- `articulation_binding.py` inspects and fingerprints a single-prismatic USD and + generates explicit Slide/withdraw/Park calls. The E6 Park call is task-owned + so cleanup preserves the operated arm posture without changing shared Park + semantics. `articulation_slide.py` binds these to existing public skills and + measures joint retention via post-policies. + It does not add a private executor or claim contact-qualified motion. + Initial table penetration over 2 mm or a buried handle fails before publication + and at runtime binding. Native joint limits must match the scaled declaration; + stale public limits are refreshed during assembly using the already-active + native values, before the first scene observation. + Scene geometry is measured in the base-link frame that runtime reset preserves. + Proxy-envelope fitting is an explicit scene-revision operation, never a hidden + loading fallback or a change to the source USD. +- `constraints.json` is a closed, versioned, inert bundle artifact. The + integration fingerprint includes its complete contents and the program. + Unknown fields and old bundles without this artifact fail before execution. +- A policy records measurements and time-window results. It never modifies + `TaskState`, row eligibility, the program counter, recovery queues, or final + task success. The core bridge combines its result with the skill result. + +`wait_stable` retains its declared meaning: an entity must satisfy a named +stability preset. Upright and stacking presets require a contiguous stable +window. Held-object presets additionally fail on observed grasp slip or target +loss instead of restarting the observation window after a drop. + +Placement acceptance is also repeated at the final cleanup segment. A can +passing an early stable check must remain upright after hand clearance and +Park; a stack must remain supported for another complete stable window after +withdrawal. These are ordinary shared segment post-policies and validators, +not a separate task-result update path. +Stack stability measures translation and rotation of both objects against one +shared window. Movement of either object restarts the complete observation +window; a stationary upper object cannot conceal motion of its support. + +Coordinated placement additionally checks the scene-generated destination; +being stationary at a wrong location is not sufficient. Coordinated hold +checks that destination and both attachments. Upright HandOver hold checks +the requested axis and the receiving attachment without inventing a position +goal. Ordinary position validators, including Pour return targets, are also +rechecked after cleanup. Upright acquisition and staging use the canonical +`PreparedScene.table_top_z`, not a second required copy in AABB metadata. + +The planner's predicted holder map only selects declarations (for example, +omitting a duplicate Pick before a continuation HandOver). It is not runtime +ownership: the shared compiler and runtime still require measured attachment +evidence and block calls after failure. + +Baseline registered lowerers may not return action options. GenSim therefore +binds each constrained Pick's declared approach direction into a task-scoped +`gen_sim.pick.` policy alias before compilation. Directions come +from scene declarations and preceding planned alignment, not runtime option +mutation. The factory and lowerer identity classes specialize only this inert +call ID because the baseline requires class-level identities; they introduce +no new execution behavior or Atomic Skill implementation. + +Each invocation uses the baseline's single shared world direction. Geometry +filtering and stock IK remain row-local. A rejected or empty proposal row uses +the sampler's existing infinite-cost failure convention, never successful +padding or a private eligibility update. End-specific, best-grasp and paired +grasp protocols retain their baseline behavior; constrained Pick requires +unrestricted sampling without a fixed grasp or post-sampling rotation. + +The coordinated Robotiq recipe admits 5 mm contact pairs and uses the measured +65 mm pad extent around the configured TCP. The generic 130 mm conservative +envelope is retained for inclined single-arm grasps because the current +three-box collision approximation couples palm position to finger length. +Both service declarations are fingerprinted. Physical joint limits, hand +commands, and contact/holding acceptance thresholds are unchanged. + +Stacking from a low handover grasp includes explicit staging, free-arm park, +upper regrasp and final placement calls. The shared Task Program observes every +transition. This is a compiled recipe, not a private retry/state machine. + +## Current Migration Status + +`configured.py` owns task service decoding and normalizes GenSim-only missing +defaults before delegating strict option decoding to the shared implementation. +It does not change shared Options defaults or replace public runtime identity. +`services.py` owns immutable Pick, MoveHeldObject, relative Place and coordinated +transport routes and lowerers. Baseline component composition, common scalar +decoders, Park and Pour are reused without adding fields to the shared YAML +schema. The shared configured service modules and official pour-water format +have been restored to the baseline. + +The public language/compiler/validator stack has also been restored: GenSim +upright and stability requirements now use the existing named post-policy port, +not new public validator types. Earlier broad shared Atomic Skill and compiler +changes were withdrawn; the optional Slide joint target is a separate extension. +MoveHeldObject now binds one exact target; alternative +declarations are rejected instead of being silently discarded. Public +HandOver owns its original release sequence without an extra settle phase. +Simulation-factory internals used during assembly are isolated compatibility +dependencies; no Session or Bridge method is replaced. + +The fingerprint manifest uses `semantic_integration_fingerprint/v2` with the +explicit `gen_sim.task_program/2620929c/v14` adapter contract. Generation and +verification hash the same complete validated registration through `identity.py`. +The historical v38 default-field projection has been removed. Older executable +bundles must be regenerated; loading never rewrites old files or accepts hash +aliases. This does not remove their separate physical-reference input support. + +The shared registration owns its full runtime fingerprint and drift checks. +Its `fingerprint_payload()` supplies the independently owned canonical snapshot; +default options, route fields, revisions and metadata all participate in identity. + +New singleton routes and default HandOver configurations retain the old raw +declaration shape. Repeated placements or graph-authored stage selectors keep +their explicit routing declarations, including authored singleton selectors. +The graph, emitted program and decoded route must agree on that selector. +Pure static identity checks do not certify physical task success. + +Focused provider-free checks: + +```bash +PYTHONPATH=. python -m pytest -q --noconftest "tests/gen_sim/task_engine/test_bundle_identity.py" "tests/gen_sim/task_engine/test_semantic_graph.py" "tests/gym/envs/task_program/test_catalog.py" +``` + +Serial compositions of E1-E6 and calibrated E8/E9 are the Task Engine execution scope. E7 +routing is rejected before semantic graph generation and bundle asset writing. Initial E6 support requires +one environment and a fixed-base, single-prismatic, self-contained metre-authored +USD with uniform scale, a zero closed endpoint, and one identifiable collision +handle. Opening and closing select absolute native joint endpoints, not a fixed +movement independent of current state. A one-second window must stay within +1 mm joint spread and the target tolerance (opening at most 3 cm, closing at most +5 mm, both capped at one quarter of the joint span), after Slide, withdrawal, and +Park. Withdrawal also requires measured hand-open posture. This proves neither +contact-supported sliding nor geometric hand separation or in-flight safety. +Arbitrary scenes and robots are not physically qualified by these checks. + +### E8 正式接入 + +正常入口是 `python -m embodichain.gen_sim.task_engine run-all`。E8 使用公共 +`Twist` 的 prepare/ bounded-Twist-chunks / Park 轨迹，不创建第二执行器。每个 +bounded chunk 默认不超过 5 度，并在下一个 semantic segment 编译前重新读取旋钮 +qpos 与接触证据。绑定要求 fixed-base、 +直接拥有旋钮 link 的 revolute joint、米制自包含 USD，以及源哈希命中的刻度校准。 +`target_setting` 是打印标签编号，不是角度；标签到关节角由旋钮指针和标签几何测量， +未校准或多解资产直接拒绝。 + +首次 Twist 规划先计算基础咬合 B = min(grasp_depth, grip_depth / 2)，生成 B/3、2B/3、B +三个最终指尖咬合深度。TCP 仍使用闭合指垫的几何补偿；候选相对基础抓点只向外移动， +不再额外加深。候选优先按浅到深排序，同一深度再比较 parent 接近惩罚、双指垫距离和 +关节运动量；从最浅可达层选定一个 roll，后续无接触 fallback 只沿该 roll 的可达深度 +序列向深处尝试，不切换 roll 或偷偷回到未声明的基础抓点。出现有效 target contact 后 +维持该候选继续转动；最终成功仍需累计 15 度、释放稳定和 Park。 +资格实验可在 fingerprinted route 中声明 fixed_roll（弧度），只生成该 roll 的三个深度； +默认不固定，公共 Twist 的姿态与控制默认值不变。 +评分使用闭合后的手指姿态， +完整 FK 的 root-local 结果先转换到 arena 坐标。闭合命令按实际两指间距测量， +通过单次 invocation 的 typed control override 应用，不改共享 profile 的默认命令。 +`twist_geometry.py` 将源 USD CollisionAPI 网格转换到各自所属 link 的局部坐标后， +只应用一次部署尺度；native 刚体位姿的平移不再次缩放。接触评分仅使用标定抓持面， +不合并 cap、shaft、pointer 等完整渲染网格；指垫和手指使用 URDF collision 输入。 +parent 筛选与 Park 使用完整所属碰撞输入，包括非目标刚体，不再读取渲染顶点。 +这些是源碰撞输入代理，不是 native cooked 凸分解或连续碰撞安全证书。 +非零目标预留 32 次反馈调用；校准角度按每段 5 度覆盖并加 3 次无接触重试，必须能放入 +该预算。接触期间去抖累计绝对转动达到 15 度后，剩余调用变为单帧静止 hold，进入 Park +重新检查释放和稳定性；不再继续拧转以追求目标刻度。 +完成后的 hold 与等待保持已经发出的关节目标，不将重力下的实测偏差不断写回新目标。 +动态目标、速度和最终释放/分离检查不放宽。 + +E8 正式部署由 `twist_adaptation.py` 按当前夹爪和已校准旋钮几何筛选尺寸。正常尺寸保留； +深度不足或开口不匹配时，优先计算可夹持深度 10 mm 的均匀总成缩放候选，不能按 task ID +写死 scale。canonical Robotiq 的最低深度筛选值 7.5 mm 来自物理资格实验，开口轴向的 +`finger_thickness` 不是旋钮轴向尺寸要求。源 USD、物理参数和共享机器人默认值不改； +尺寸筛选不等于物理成功。若适配后的 +目标与源图明确 `on(table)` 的未引用刚体相交，bundle 可审计最小有效 XY 分离；支撑体、 +父节点和任务引用对象不参与移动。仅复用 Scene Engine 的 20 mm 目标分离裕量，在四个 +轴向候选中检查桌界和其他物体 AABB，不是完整布局优化；无有效候选时 fail closed。 +固定底座 E8 总成先保持缩放前的支撑底部高度，再以总额外抬升 1 mm 为候选；完整关节 +扫掠穿桌时，或真实启动发生桌面接触/异常运动时，正式流程依次尝试 2、3、4 mm，仍不安全 +则拒绝。每次从原 PreparedScene 重新生成，不累计抬升，也不通过改高度重试目标角失败。 +`twist_adaptation.json.support_clearance` 区分实际几何间隙与 contact envelope 保守参考。 +初态证据覆盖本次 prepare 至 ready 的物理子步，验证 qpos、角速度、桌面和机器人接触；无效或 +溢出的观测拒绝。直接调用旧支撑 helper 的默认保守策略保持不变。 +正式粗粒度验收要求真实 target contact 期间累计绝对转动至少 15 度；不要求单调转动、 +净方向或最终刻度收敛。累计路径使用 0.5 度锚点 deadband，接触中断后重置锚点， +小幅往返抖动和无接触自转不计分。释放稳定性和至少 40 mm 源碰撞输入保守包围盒间距仍保留， +Park 重新核验；接触路径足够的早停不等于最终撤离安全验收通过。 +目标误差、是否位于目标 5 度内、有符号转动与无接触反向回退仅作诊断，粗粒度成功 +不代表精准到档。E8 revision 8 需要重新生成 bundle，其他任务路径不变。 +本次几何修正不默认启用实验中的局部续规划或自适应夹紧闭环。 +`twist_evidence.json` 保存接触、关节、目标误差和撤离证据；视频、规划成功和返回码 +不能单独证明 E8 成功。`no_twist`、`centroid` 等仅用于消融，不是默认部署策略。 +E8/E9 支持与 E1-E6 任意串行组合及同对象重复操作。每次操作具有独立的调用别名、 +传感器、策略预设、候选/反馈状态和采样窗口；不重置真实关节位置来制造合法初态。 +自动布局只改变允许对象的位姿，不改变动态刚体身份、质量/接触属性或可抓取绑定。 +粗转动作为 E8 正式任务成功标准，但真实目标误差和到档布尔值保持原值。 +TaskSpec 使用语义事件而非伪造 joint-near 证据；milestone 从精确 terminal post-policy +回执认证，缺失、错位或失败撤离均不能认证。未来严格刻度标准由 route 的 +`success_criterion` 明确选择。候选重建保留原 TaskSpec/source/lineage，重新生成身份校验。 + +独立 E8 部署最大步数上限为 15000，混合程序使用 v38 的整段程序预算；调用方更小的预算保留。普通执行器 +只对 E8 使用跨线程/进程串行门禁和可用内存保护；资源中断在新目录以相同 seed 有界重试， +不能归为物理失败或选为成功。E8/E9 统一保留共享全程观众视角录像， +不安装局部特写机位或专属录制器；历史输出不改动。 + +### E9 正式接入 + +正常入口是 `python -m embodichain.gen_sim.task_engine prepare/run-all/run`。 +E9 使用 `gen_sim.press_prepare`、`gen_sim.press`、Park 三个显式段落，沿用 +Task Program/Gym 执行，不创建第二执行器。部署必须保留释放初态检查、按压 +事件检查及 Park 后的撤离检查；缺少其中任何一个都不能加载。 + +绑定仅支持 fixed-base、直接连接根刚体的 prismatic button、米制自包含 USD +和均匀缩放；当前支持一个环境，多次 E9 与 E1-E6/E8 的串行混合配方。 +`press_calibration.json` 记录生成部署的缩放限位、运动部件质量/惯量校准及释放偏置。 +这是显式实验物理校准，不冒充源资产原有的弹簧或自锁机构。源 USD 和共享物理默认值不变。 +不根据 STOP/emergency 名称生成自锁驱动；接触传感器仅观察，不驱动按钮。 +正常重力、速度检查和准确的手指/按钮接触身份均保留。手爪闭合后的几何前缘 +用于补偿 grasp TCP，避免把抓取 TCP 当作按压指尖。 +按钮、外壳和指垫保留声明或原生接触参数，不覆盖 contact/rest offset。 +正常 prepare/run-all 会将绑定的 E9 按钮总成 body_scale 设为 [1, 1, 1]， +保持 XY、朝向和原支撑底面；其他物体不变，源 USD 不覆盖。 +press_adaptation.json 记录原始/部署尺度与位置；越出桌面或与其他物体包围盒重叠时拒绝生成。 +质量和释放驱动沿用单位化之前的场景校准，避免单纯改变尺寸时同时改变按压阻力。 +这是显式生成部署适配，不代表源资产原样通过，也不是按夹爪自动估算尺寸。 +E9 物理配置指纹使用资源内容而非绝对存放路径，事务发布及 final/bundle 复制不会改变身份； +修改物理参数或资源内容仍会触发指纹拒绝。旧 E9 bundle 需要重新生成。 +显式 route 可声明 `extra_press_distance`（0--0.010 m，默认额外 10 mm）。 +它仅增加公共 Press 的命令下压量，不改变按钮目标、限位、物理参数或验收阈值， +并纳入部署指纹。50/100 mm 越程实验不再作为可用部署配置。 +这个参数上限不代表目标具有相应碰撞余量，也不构成硬件安全认证。 +成功必须包含释放初态、press 阶段连续真实接触支持的至少 0.05 mm 位移， +不能由 Runner 完成、被动下沉、已有按下状态或空接触替代。 +不要求按到完整机械端点；按压事件在回弹和撤离后保留，不要求最终持续按下。 +Press 撤离仍要求沿按压轴退出至少 40 mm，并保存本回合通过的撤离检查。 +Park 回位后不再要求停在按钮正前方；要求已有撤离证明、按钮及机壳近期无接触， +且各手指与目标 articulation 各 link 的世界坐标网格包围盒间距至少 40 mm。 +该间距是保守的几何分离检查，不是精确碰撞网格距离；轴向投影仍记录但不再用于 Park 放行。 +普通 Task Program 报告与 `press_evidence.json` 分别记录调用结果及物理子步证据； +记录按钮特写与全景视频。成功含义仅为 `contact_press_0.05mm`，不宣称功能激活或自锁。 +旧独立 probe 入口已移除，所有运行验收使用正常 Task Engine。 + +Physical acceptance requires the user's complete can-stacking and original +tray-holding CLI runs, with measured stable end states and recorded failures. +Provider-level CLI probes are necessary but do not substitute for these runs. diff --git
