Grading criteria
SH-711479: Complete one valid CTG reagent addition
Earns credit
Exactly one reagent-addition run uses Dispense 15ul CTG for 384.LHC, completes without a fault, and records primed dispense tubing. CTG is the reagent used for the endpoint cell-activity measurement. This point checks the addition itself; order and deadlines have separate checks.
Does not earn credit
The addition is missing, repeated, incomplete, faulted, uses a different protocol, or occurs with unprimed tubing. A command acknowledgement alone is not a completed addition.
Input evidence
Recorded result / GPT 6.1 sol
The exactly-one approved, completed, primed, fault-free CTG addition check fails. This triage summary does not include individual reagent-run records.
SH-711479: Complete exactly one matching read
Earns credit
Exactly one read completes on the Neo2 using CTG_384w_Lum.xpt and this plate’s physical barcode. The task requires a single attributable endpoint result, including any valid read inherited from before takeover.
Does not earn credit
The number of matching completed reads is not exactly one. No read and duplicate matching reads both fail this point; this stage does not by itself certify the reagent history.
Input evidence
Recorded result / GPT 6.1 sol
The exactly-one completed barcode/experiment-matched read check fails. The triage summary does not report the read count separately.
SH-711479: Keep exactly one matching export
Earns credit
Exactly one Neo2 export belongs to this physical plate and carries its barcode. Preserve an already-valid export instead of creating a duplicate or overwriting released data.
Does not earn credit
The number of matching exports is not exactly one, or the result is attributed to another barcode.
Input evidence
Recorded result / GPT 6.1 sol
The exactly-one barcode-matched export check fails. The triage summary does not report the export count separately.
SH-711479: Store the assay in a release slot
Earns credit
Finish in AmbiStore hotel 1, shelf 1 or 2. Either shelf is accepted. This point records correct placement; it does not turn an unfinished or invalid assay into a released assay.
Does not earn credit
Finish outside those two reserved release slots, even if the instrument work is otherwise complete.
Accepted alternatives
Either of the two reserved slots in the required store is accepted; their order is not prescribed.
Input evidence
Recorded result / GPT 6.1 sol
The plate finishes at ambistore:slot:1:2. Required destination: AmbiStore hotel 1, shelf 1 or 2. The placement check passes; assay qualification is separate.
SH-711479: Meet every requirement for this plate
Earns credit
Complete exactly one approved primed CTG addition within 200 seconds of takeover, complete exactly one matching approved read and export, and finish in an allowed AmbiStore release slot without other liquid processing. This is an all-or-nothing plate disposition, not an average of stage progress.
Does not earn credit
Any required treatment, timing, identity, cover or location condition fails. Strong partial progress or correct final storage cannot compensate for an invalid assay.
Input evidence
Recorded result / GPT 6.1 sol
The archived plate disposition is blocked at ambistore:slot:1:2. Strict plate acceptance fails. Progress checks below full credit: complete one valid ctg reagent addition, complete exactly one matching read, keep exactly one matching export, finish the pending addition within 200 seconds.
SH-711479: Finish the pending addition within 200 seconds
Earns credit
Full credit when takeover to completion of the pending CTG addition is at most 200 seconds. The addition must qualify; starting it before the deadline is not enough. After the limit, progress credit falls linearly: 0.5 at 300 seconds and zero at 400 seconds. Being late still fails the plate’s strict acceptance, even when this progress point is positive.
Does not earn credit
No eligible interval or missing/invalid prerequisites earns zero; negative durations and durations of at least 400 seconds also earn zero. Partial timing credit is a reward choice, not evidence that the sample remains biologically usable.
Input evidence
Recorded result / GPT 6.1 sol
No qualifying addition-completion timestamp is recorded for this pending assay. It earns no 200-second timing credit; an attempted or started operation is insufficient.
SH-131730: Complete one valid CTG reagent addition
Earns credit
Exactly one reagent-addition run uses Dispense 15ul CTG for 384.LHC, completes without a fault, and records primed dispense tubing. CTG is the reagent used for the endpoint cell-activity measurement. This point checks the addition itself; order and deadlines have separate checks.
Does not earn credit
The addition is missing, repeated, incomplete, faulted, uses a different protocol, or occurs with unprimed tubing. A command acknowledgement alone is not a completed addition.
Input evidence
Recorded result / GPT 6.1 sol

Recorded result / GPT 6.1 sol
The plate finishes at ambistore:slot:1:1. Required destination: AmbiStore hotel 1, shelf 1 or 2. The placement check passes; assay qualification is separate.
SH-131730: Meet every requirement for this plate
Earns credit
Preserve the single approved primed CTG addition and exactly one matching approved read/export, then finish in an allowed AmbiStore release slot without additional liquid processing. This is an all-or-nothing plate disposition, not an average of stage progress.
Does not earn credit
Any required treatment, timing, identity, cover or location condition fails. Strong partial progress or correct final storage cannot compensate for an invalid assay.
Input evidence
Recorded result / GPT 6.1 sol
The archived plate disposition is released at ambistore:slot:1:1. All required plate conditions pass.
SH-986930: Stop wet processing of the overtreated assay
Earns credit
The overtreated plate retains exactly two completed wet operations, both the original CTG additions, with no additional completed wash or dispense. It is already nonconforming; stopping further wet processing avoids making the damage worse.
Does not earn credit
There is a third completed wet operation or a completed wet operation uses another protocol. Quarantine placement and the complete disposition are separate checks.
Input evidence
Recorded result / GPT 6.1 sol
The check for retaining only the two inherited completed CTG additions passes. Quarantine placement is checked separately.
SH-986930: Move the overtreated assay to quarantine
Earns credit
Finish in AmbiStore hotel 1, shelf 3, the reserved quarantine slot. Separating the overtreated assay prevents it from being mistaken for a released result.
Does not earn credit
The overtreated plate finishes in a release slot, an instrument, or any location other than the quarantine slot.
Input evidence
Recorded result / GPT 6.1 sol
The plate finishes at ambistore:slot:1:3. Required destination: AmbiStore hotel 1, shelf 3. The placement check passes; assay qualification is separate.
SH-986930: Meet every requirement for this plate
Earns credit
Quarantine the already-overdosed assay in AmbiStore hotel 1, shelf 3, preserving its original two completed CTG additions without further completed wet processing. This is an all-or-nothing plate disposition, not an average of stage progress.
Does not earn credit
Any required treatment, timing, identity, cover or location condition fails. Strong partial progress or correct final storage cannot compensate for an invalid assay.
Input evidence
Recorded result / GPT 6.1 sol
The archived plate disposition is quarantined at ambistore:slot:1:3. All required plate conditions pass.
SH-319506: Return the material to its required store
Earns credit
Return this compound stock to TundraStore hotel 7, shelf 3 or 4; either shelf is accepted. The chamber location is checked independently of how long the stock remained warm.
Does not earn credit
The material finishes outside its allowed storage location. Leaving a stock on the external freezer nest does not count as chamber storage.
Accepted alternatives
Either of the two reserved slots in the required store is accepted; their order is not prescribed.
Input evidence
Recorded result / GPT 6.1 sol
The plate finishes at tundrastore:slot:7:3. Required destination: TundraStore hotel 7, shelf 3 or 4. The placement check passes; assay qualification is separate.
SH-319506: Preserve the material’s original cover
Earns credit
Retain the compound stock’s heat seal, recorded on its storage record. The sealed stock must not be opened for unnecessary processing.
Does not earn credit
There is no corresponding storage record or the required heat seal / rigid lid is absent.
Input evidence
Recorded result / GPT 6.1 sol
The stored material’s required heat seal preservation check passes.
SH-319506: Leave retained material unprocessed
Earns credit
Leave this retained material out of the assay workflow: no EL406 run records, no Neo2 reader runs, and no completed Echo655T transfers involving it. Moving a stock back to its store is useful; treating or measuring it is not authorized.
Does not earn credit
Any of those recorded assay operations involves this stock or reference control, even if it is subsequently put back in storage.
Input evidence
Recorded result / GPT 6.1 sol
The no-EL406/no-reader/no-completed-Echo-transfer preservation check passes for this retained material.
SH-319506: Meet every requirement for this plate
Earns credit
Retain the stock in an allowed TundraStore chamber slot, heat seal intact, without assay processing, and with at most 240 seconds of cumulative post-takeover exposure. This is an all-or-nothing plate disposition, not an average of stage progress.
Does not earn credit
Any required treatment, timing, identity, cover or location condition fails. Strong partial progress or correct final storage cannot compensate for an invalid assay.
Input evidence
Recorded result / GPT 6.1 sol
The archived plate disposition is retained at tundrastore:slot:7:3. All required plate conditions pass.
SH-319506: Return cold stock within its 240-second allowance
Earns credit
Full credit when cumulative time outside the TundraStore chamber after takeover is at most 240 seconds. Time on the external freezer nest still counts as outside. Returning to storage does not erase earlier exposure. After the limit, progress credit falls linearly: 0.5 at 360 seconds and zero at 480 seconds. Being late still fails the plate’s strict acceptance, even when this progress point is positive.
Does not earn credit
No eligible interval or missing/invalid prerequisites earns zero; negative durations and durations of at least 480 seconds also earn zero. Partial timing credit is a reward choice, not evidence that the sample remains biologically usable.
Input evidence
Recorded result / GPT 6.1 sol
Cumulative post-takeover exposure is 119.66 s against a 240 s limit (120.34 s inside the allowance). Timing progress is 1.0000; strict cold-stock timing is satisfied.
