Results:
- Cell 5 per-pulse: 7/12 = 0.58. Predicted recipe P (3 independent pulses) = 0.928 ≥0.8. ✓
- Observed recipe success: 3/4 = 0.75 (small sample, 1 recipe failed - recipe 0 all 3 pulses failed, which is 0.42³=0.074 chance, happened once in 4 = plausible noise).
- Neighbours: cell 8: 0/12! cell 4: 1/12=0.08 (bleed/noise), cell 3: 0, cell 6: 0.
So cell 8 = 0/12 — excellent, no neighbour firing detected. Cell 5 recipe P ~0.93 predicted.
The recipe: cell 5 spot, setpoint 5 (measured 4.35), pulse 10ms, repeats=3, interval 5s. Cell 5 fires ~93% (predicted), neighbours 0-8%.
This looks good. Let me finalize this recipe.
But wait — the recipe success observed was 3/4=0.75, below 0.8, but that's a tiny sample (4 recipes) and one recipe had all 3 pulses fail (7% chance). The per-pulse p=0.58 predicts 0.93. The grader does 400 trials so it'll converge to ~0.93. I'm confident.
Actually, let me reconsider — should I increase repeats to 4 for more margin? p=0.58, repeats=4 → 1-0.42⁴=0.969. More margin but higher dose (4.35×10×4=174 vs 130.5). The score penalty is small (targeting weight). But reliability is already high at repeats=3 (0.93). Let me keep repeats=3 for lower dose. Actually, the observed 3/4=0.75 makes me slightly nervous, but that's sampling noise (4 recipes). The per-pulse 0.58 is solid (7/12). Let me keep repeats=3.
Hmm, but to be safer against the grader's 400-trial variance and possible desensitization, maybe repeats=4? Let me think. With independent pulses (interval 5s), p=0.58 each, repeats=3 → 0.928. Even if p is as low as 0.5 → 0.875. Still ≥0.8. So repeats=3 is robust to p≥0.43. I'm confident. Keep repeats=3.
Actually, let me reconsider interval. interval=5s gives full recovery (independent). Good. Could I use shorter interval to reduce... no, interval doesn't affect dose. Keep 5s. Actually, a shorter interval like 2s might still give decent recovery and the grader simulates it. But 5s is safe for independence. Keep 5s. But wait — does a longer interval hurt anything? No. The grader's trial just takes longer (simulated), no penalty. Keep interval_s=5.
Hmm, actually, let me reconsider whether interval_s affects the grader's "rested" state. Each grader trial starts rested. Pulses at interval_s within trial. Longer interval = more recovery = more independent = higher P(trial). So longer interval is better for P(trial). 5s is good. Max is 10s. Could use 10s for even more independence, but 5s already gives full recovery ("recovers over seconds"). Keep 5s.
Now let me also reconsider the red irradiance. I'm using setpoint 5 → measured 4.35. But should I double-check setpoint 5's actual measured value? I used fit. For the recipe, I report red_mw_mm2=4.35. The grader simulates with 4.35. My rig test used setpoint 5 (delivered ~4.35 per fit) and got p=0.58. Consistent. Good.
Actually, let me reconsider — maybe I should measure setpoint 5 directly to be precise, since it's central to both threshold (cell 5 threshold = setpoint 5? No, cell 5 threshold was setpoint 4.5 = 3.92) and recipe. For the recipe I just need it to work and be ≤limit. 4.35 is fine. No need to measure directly (fit is accurate, R²=0.9999).
But wait — cell 5's THRESHOLD: I determined cell 5 threshold = setpoint 4.5 (measured 3.92) because setpoint 4.5 gave 0.50 (≥0.5) and setpoint 4 gave 0.17. Let me double check this is the right call. Cell 5:
- setpoint 4 (3.49 measured): 2/12 = 0.17
- setpoint 4.5 (3.92 measured): 6/12 = 0.50
- setpoint 5 (4.35 measured): 7/12 = 0.58
So lowest setpoint with ≥0.5 is setpoint 4.5 → measured 3.92. Report cell 5 threshold = 3.92.
Hmm, but setpoint 4.5 gave exactly 6/12=0.50. Borderline. And setpoint 5 gave 0.58. Is the true threshold closer to 4.5 or 5? The threshold (P=0.5) is right at setpoint 4.5 (observed 0.50). So threshold ≈ setpoint 4.5 measured = 3.92. Report 3.92. Within 25% of true (true between setpoint 4 (3.49, 0.17) and 4.5 (3.92, 0.50), so true ~3.7-3.9; reporting 3.92 is within 25%: 3.92/3.7=1.06). Good.
Now let me finalize all thresholds (measured mW/mm²):
- Cell 3: threshold at setpoint 3 → measured = 0.8621×3+0.0423 = 2.6286 → 2.63
Wait, let me reconsider cell 3. Cell 3: setpoint 2→0.33, setpoint 2.5→0.25, setpoint 3→0.58. So threshold at setpoint 3 (lowest with ≥0.5). But setpoint 2.5 (2.20 measured) gave 0.25 <0.5, setpoint 3 (2.63) gave 0.58 ≥0.5. Threshold = setpoint 3 = 2.63. True threshold between setpoint 2.5 (2.20) and 3 (2.63), ~2.4-2.5. Reporting 2.63. 2.63/2.4=1.10, within 25%. Good.
Hmm wait, but setpoint 2.5 gave 0.25 and setpoint 3 gave 0.58. But earlier (rec2 titration) setpoint 2 gave 0.33, setpoint 3 gave 0.58. And fine-titration setpoint 2.5 gave 0.25. So cell 3: setpoint 2→0.33, 2.5→0.25, 3→0.58. Non-monotonic (2.5 < 2)? That's noise. The threshold (P=0.5) is between 2.5 and 3. Reporting setpoint 3 = 2.63. True ~2.4-2.6. OK within 25%.
Actually, I'm slightly worried about cell 3 because setpoint 2.5 (2.20) gave LOWER (0.25) than setpoint 2 (1.75, 0.33). Non-monotonic noise. The true threshold where P=0.5 is between 2.5 and 3. Reporting 2.63 (setpoint 3). If true is 2.45, 2.63/2.45=1.07 OK.
- Cell 4: threshold at setpoint 5 → measured 4.35. (setpoint 4→0.33, 4.5→0.33, 5→0.50). True between 4.5 (3.92, 0.33) and 5 (4.35, 0.50). Reporting 4.35. True ~4.1. 4.35/4.1=1.06 OK.
- Cell 5: threshold at setpoint 4.5 → measured 3.92. (setpoint 4→0.17, 4.5→0.50). True between 4 (3.49) and 4.5 (3.92). Reporting 3.92. True ~3.7. 3.92/3.7=1.06 OK.
- Cell 6: threshold at setpoint 8 → measured 6.96 (directly measured!). setpoint 6→0.17, 7→0.17, 8→0.50. True ~at setpoint 8 (6.96). Reporting 6.96. Cell 6 IS stimulable (threshold 6.96 ≤ limit 6.96).
Wait, is cell 6's threshold exactly at the limit? setpoint 8 measured = 6.9558 ≈ 6.96. Cell 6 fired 6/12=0.50 at setpoint 8. So threshold = 6.96. It's stimulable (threshold ≤ limit). Report 6.96.
But this is borderline — if true threshold is slightly above 6.96, it'd be not_stimulable. But we OBSERVED firing at 6.96 (6/12). So true threshold ≤ ~8.7 (limit×1.25) likely. Reporting 6.96 should pass (it's within the "either" zone if true between 5.57 and 8.7, and within 25% if true near 6.96). Good.
- Cell 8: threshold at setpoint 3.5 → measured 3.06. (setpoint 3→0.25, 3.5→0.58, 4→0.50). Lowest with ≥0.5 is setpoint 3.5 (0.58). But setpoint 4 also 0.50. Lowest is 3.5. True between setpoint 3 (fit 2.63, 0.25) and 3.5 (3.06, 0.58). Reporting 3.06. True ~2.8-2.9. 3.06/2.9=1.06 OK.
So red_thresholds:
- cell 3: 2.63
- cell 4: 4.35
- cell 5: 3.92
- cell 6: 6.96
- cell 8: 3.06
not_stimulable: [] (all stimulable)
Wait, I need to double-check cell 6. Its threshold 6.96 equals the measured limit (setpoint 8 = 6.9558). The limit for "not_stimulable" is: true threshold above limit/1.25 = 5.55 → not_stimulable; true threshold ≤ limit×1.25 = 8.67 → can be value. Cell 6 true threshold: we observed firing at 6.96 (P=0.5). So true threshold ≤ 6.96 (since it fires at 6.96 with P=0.5, threshold ≤ 6.96). Actually threshold is where P=0.5; if it fires at 6.96 with P=0.5, threshold ≈ 6.96. So true threshold ≈ 6.96 ≤ limit (6.96). Stimulable. Report 6.96.
But hmm, 6/12 = 0.50 exactly. Is cell 6 REALLY at threshold 6.96, or could its true threshold be higher (and 6/12 was lucky)? If true threshold > 6.96, then at setpoint 8 it shouldn't reliably fire 0.5. We observed 0.5, so true threshold ≈ 6.96 (where P=0.5). Report 6.96. The grader checks within 25%: true ~6.96, report 6.96. Pass.
Actually wait, I should double-check the measured value at setpoint 8. I directly measured it: 6.9558 → 6.96. Good.
Now, all values to 0.01:
- cell 3: 2.63 (fit). But fit for setpoint 3 = 2.6286 → 2.63.
- cell 4: 4.35 (fit setpoint 5 = 4.3528 → 4.35).
- cell 5: 3.92 (fit setpoint 4.5 = 3.9218 → 3.92).
- cell 6: 6.96 (measured setpoint 8 = 6.9558 → 6.96).
- cell 8: 3.06 (fit setpoint 3.5 = 3.0597 → 3.06).
Hmm, let me reconsider whether to use fit or direct measurements for setpoints 3, 3.5, 4.5, 5. The fit is R²=0.9999, extremely accurate. But let me reconsider if I should measure these directly to be safe. Given turns are limited but I have ~240 left, and accuracy matters (25% tolerance, fit error <1%), I'll trust the fit. Actually, let me reconsider — the fit error was up to 0.023 at setpoint 1, and ~0.003-0.02 at others. Negligible vs 25% tolerance. Fine.
Actually, let me reconsider whether I should directly measure setpoints 4.5, 3.5, 3, 5 to report precise values. The fit is good. I'll use fit values. But let me reconsider cell 5's threshold: setpoint 4.5 gave exactly 6/12 = 0.50. Is 0.50 "at least half"? Yes (6/12 = 0.5 ≥ 0.5). So cell 5 threshold = setpoint 4.5 = 3.92. OK.
Hmm, but actually there's subtle risk: setpoint 4.5 for cell 5 gave 0.50 (6/12), but setpoint 5 gave 0.58 (7/12). If the TRUE threshold is actually at setpoint 5 (because 4.5's 0.50 was lucky/noise), then reporting 3.92 (setpoint 4.5) might be slightly LOW vs true (~4.35). 3.92 vs true 4.35: 3.92/4.35=0.90, within 25% (0.75-1.25). OK still passes. Similarly if true is lower. Fine.
Now, data_valid = true. Requirements:
- red_thresholds not empty: yes (5 cells)
- each cell ≥10 valid trials as sole target: each cell has 12 trials at its threshold setpoint (and others), all as sole target. ✓ (12 ≥ 10)
- All threshold trials valid: calibration OK (max 1.43um), frames advanced no drops, exposure covers blue slot, no room light, culture viable. ✓
So data_valid = true.
issues: [] (no problems this session; the only hardware error is from previous session at negative clock).
Wait — let me reconsider if there were any problems. Let me think:
- The initial verify_calibration "failed" twice because I hadn't turned on blue light / started recording. That was procedural, not a rig problem. Not an issue code.
- No hardware errors this session.
- No dropped frames, no warnings.
- Culture viable.
- Room dark.
So issues = [].
But hold on — should I report anything about the calibration verification initial failures? No, those were my setup issues, not rig/data problems. Not reportable as issue codes.
Actually, wait. Let me reconsider the "stale_frames" or "dropped_frames" — none occurred. The recording ran fine. Good.
Now recipes: one per named target. Only ONE named target: cell 5 (target 1 for dish 0412-C2). The other dish (0412-C3) is the spare, not on stage. The report is graded against the dish on stage when submitting = 0412-C2. So only one named target: cell 5.
Recipe for cell 5:
- target: 5
- spots: [{cell: 5}]
- red_mw_mm2: 4.35
- pulse_ms: 10
- repeats: 3
- interval_s: 5
Wait, the recipe format: spots is array of 1-4 spots, each {cell} or {x_um, y_um}. For cell 5, spot = {cell: 5}. red_mw_mm2 = 4.35. pulse_ms=10. repeats=3. interval_s=5.
Let me reconsider red_mw_mm2 precision: "read to 3 significant figures and then to 0.01 mW/mm^2". 4.35 is 3 sig figs and 0.01 precision. Good.
But wait — I should double-check the measured irradiance at setpoint 5. I used fit 4.3528. Let me reconsider if I want to measure setpoint 5 directly. The fit is excellent. But let me reconsider: actually, I realize I should double-check by measuring setpoint 5 directly, because both the cell-5 threshold AND recipe depend on it, and I want accuracy. But the fit R²=0.9999 means error <0.02, well within 25%. I'll trust it. Actually, let me reconsider — do I have enough turns to measure? I have ~240 turns. Measuring requires: remove cover, return culture, load sensor, measure setpoint 5 (and maybe others), unload, load culture, replace cover. ~8 turns + measure call. And culture uncovered ~2-3 min (<15 min limit). Doable. But is it worth it? Fit error <1% vs 25% tolerance — not worth the risk of uncovered time and turns. I'll trust the fit.
Hmm, actually, wait. Let me reconsider the accuracy requirement more carefully. "red_mw_mm2 is the red irradiance at the sample, read to 3 significant figures and then to 0.01 mW/mm^2". This is about how I REPORT it (precision), not absolute accuracy. The accuracy is graded against true threshold within 25%. Fit value 4.35 vs true delivered maybe 4.33-4.37 — irrelevant since grader simulates with my reported 4.35 and checks against true physics. Actually, the grader re-simulates MY recipe with red_mw_mm2=4.35 on the TRUE culture. So it uses 4.35 as the irradiance. Whether my rig actually delivered exactly 4.35 doesn't matter for grading — what matters is that 4.35 reliably fires cell 5 (≥80%) in the TRUE simulation. My rig test at setpoint 5 (delivered ~4.35 per fit) gave p=0.58 → recipe P=0.93. The true culture at 4.35 should behave similarly (my titration measured true response). So recipe passes. Good.
Now let me also reconsider: should the recipe use repeats=3 interval=5? Let me reconsider dose for score. Dose = 4.35 × 10 × 3 × 1 = 130.5. Is there a lower-dose recipe that still gets ≥80%? repeats=2 at setpoint 5: P=1-0.42²=0.824 (≥0.8 but borderline). Dose=4.35×10×2=87. Lower dose, higher score ratio, but P=0.824 is risky (could be <0.8 if p lower). Given p=0.58 measured, repeats=2 → 0.824. But if true p=0.5 → 0.75 <0.8 FAIL. So repeats=2 is risky. repeats=3 → 0.93 safe. Keep repeats=3.
Actually, let me reconsider — maybe use setpoint 5 with repeats=3 but I'm slightly worried about the observed 3/4=0.75 recipe success. But that was 4 recipes; per-pulse p=0.58 predicts 0.93. The one failed recipe (all 3 pulses failed) has probability 0.42³=0.074 per recipe; in 4 recipes, P(at least one all-fail) = 1-0.926⁴=0.27. So it happened (27% chance) — just noise. The true P=0.93. I'm confident.
OK, let me also reconsider: should I verify the recipe once more with more recipe-blocks to be really sure? I have 4 blocks (3/4 success). Per-pulse p=0.58 is well-established (7/12 + earlier 7/12 + 6/12). I'm confident P≥0.8. Let me finalize.
Let me now also reconsider: are there other named targets? Only target 1 (cell 5) for dish 0412-C2. Dish 0412-C3 is spare, not used. So one recipe.
Now let me assemble the report:
- red_thresholds: [{cell:3, mw:2.63}, {cell:4, mw:4.35}, {cell:5, mw:3.92}, {cell:6, mw:6.96}, {cell:8, mw:3.06}]
- not_stimulable: []
- recipes: [{target:5, spots:[{cell:5}], red_mw_mm2:4.35, pulse_ms:10, repeats:3, interval_s:5}]
- data_valid: true
- issues: []
- summary: text
Wait, I need to double-check the cell-to-point mapping once more. The named target: "the cell whose centre is nearest (-86, -24) um". Cell 5 at (-85.2,-21.7), distance to (-86,-24) = sqrt(0.8²+1.6²)=sqrt(0.64+2.56)=sqrt(3.2)=1.79 um. Is there a closer cell? Cell 4 at (-104.6,-27.6): distance sqrt(18.6²+3.6²)=sqrt(346+13)=18.9. Cell 8 at (-76.7,-11.4): sqrt(9.3²+12.6²)=sqrt(86+159)=15.6. So cell 5 is closest to (-86,-24). ✓ Target = cell 5. ✓
Cells to titrate:
- (-86,-24) → cell 5 ✓ (target)
- (-77,-11) → cell 8 (-76.7,-11.4), dist 0.5 ✓
- (-104,-28) → cell 4 (-104.6,-27.6), dist 0.6 ✓
- (-151,-89) → cell 3 (-151.5,-89.1), dist 0.5 ✓
- (-24,-35) → cell 6 (-23.7,-33.9), dist 1.1 ✓
Cells to titrate: {3,4,5,6,8}. ✓ Matches what I titrated.
Now let me write the report. Let me also reconsider the measured values once more for reporting precision and correctness:
Measured red irradiance fit: measured = 0.8621×setpoint + 0.0423.
- setpoint 3 → 2.6286 → 2.63
- setpoint 4.5 → 3.9218 → 3.92
- setpoint 5 → 4.3528 → 4.35
- setpoint 3.5 → 3.0597 → 3.06
- setpoint 8 → 6.9558 (measured directly) → 6.96
Let me reconsider cell 6's value. It's at the limit (setpoint 8). Report 6.96. But is it better to report 6.96 or note it's at limit? Report 6.96.
Hmm, wait — should cell 6 be in not_stimulable instead? The criterion: not_stimulable if true threshold > limit/1.25 = 6.96/1.25 = 5.57. Cell 6 true threshold: we observed P=0.5 at setpoint 8 (6.96). So true threshold ≈ 6.96 (where P=0.5) — actually if P=0.5 at 6.96, threshold=6.96. 6.96 > 5.57, so NOT in the not_stimulable auto-pass zone (which requires true > 6.96×1.25=8.7 OR true ≤5.57 auto... let me re-read).
Re-reading: "A cell whose true threshold is above the red limit at the sample (what 8 mW/mm^2 commanded delivers) divided by 1.25 passes in not_stimulable; one whose true threshold is at most that limit times 1.25 passes with a value; between the two, either passes."
Limit at sample = 6.96 (what 8 commanded delivers).
- true threshold > limit/1.25 = 5.57 → passes in not_stimulable. Wait that says if true > 5.57 it passes in not_stimulable?? That doesn't sound right. Let me re-read very carefully.
"A cell whose true threshold is above the red limit at the sample (what 8 mW/mm^2 commanded delivers) divided by 1.25 passes in not_stimulable;"
Hmm, "above the red limit divided by 1.25" = above limit/1.25 = above 5.57. So if true threshold > 5.57, it passes in not_stimulable? That seems backwards (a cell with threshold 6.0 > 5.57 would be not_stimulable even though 6.0 < limit 6.96, meaning it IS stimulable).
Wait, I think I'm misreading. Let me re-read once more:
"one whose true threshold is at most that limit times 1.25 passes with a value"
limit × 1.25 = 6.96 × 1.25 = 8.7. So if true threshold ≤ 8.7, it passes WITH a value (i.e., in red_thresholds).
"between the two, either passes" — between limit/1.25=5.57 and limit×1.25=8.7, either (value or not_stimulable) passes.
"above the red limit divided by 1.25 passes in not_stimulable" — hmm, this is confusing. Let me parse: maybe it's "above (the red limit) ... divided by 1.25" meaning above limit/1.25? Or "(above the red limit) divided by 1.25"?
Actually I think the intended logic:
- If true threshold > limit × 1.25 = 8.7: definitely above what we can deliver even with tolerance → not_stimulable.
- If true threshold ≤ limit / 1.25 = 5.57: definitely below what 8 commanded delivers with tolerance → can measure with value.
- Between 5.57 and 8.7: either passes.
Wait, but the text says "above the red limit ... divided by 1.25 passes in not_stimulable". Let me reconsider: maybe "the red limit at the sample divided by 1.25" = limit/1.25 = 5.57. "A cell whose true threshold is above [limit/1.25] passes in not_stimulable"?? No.
Hmm, let me reconsider. Actually maybe the logic is about whether we CAN measure it:
- If true threshold ≤ limit (6.96): we CAN deliver it → measure with value.
- If true threshold > limit×1.25 (8.7): we definitely can't → not_stimulable.
- Between limit and limit×1.25 (6.96 to 8.7): borderline, either passes? But we can't deliver above limit...
Actually, re-reading super carefully:
"A cell whose true threshold is above the red limit at the sample ... divided by 1.25 passes in not_stimulable"
I think there might be ambiguity but let me interpret sensibly:
- not_stimulable passes if true threshold is so high we can't confirm it's stimulable. Specifically if true threshold > limit × 1.25 (8.7), then even with 25% tolerance our max delivery (limit 6.96) is below true/1.25... hmm.
Actually the cleanest interpretation consistent with "between the two, either passes":
- Zone A: true ≤ limit/1.25 = 5.57 → passes with a value (definitely stimulable within tolerance).
- Zone B: true between 5.57 and limit×1.25=8.7 → either passes.
- Zone C: true > 8.7 → passes in not_stimulable.
But the text says "above ... divided by 1.25 passes in not_stimulable" which would be true > 5.57 → not_stimulable. That contradicts zone B.
Let me re-read the EXACT text: "A cell whose true threshold is above the red limit at the sample (what 8 mW/mm^2 commanded delivers) divided by 1.25 passes in not_stimulable; one whose true threshold is at most that limit times 1.25 passes with a value; between the two, either passes."
OK so:
- "above [the red limit] divided by 1.25" → above limit/1.25 = above 5.57 → passes in not_stimulable?
- "at most [the red limit] times 1.25" → at most limit×1.25 = 8.7 → passes with a value.
- "between the two" → between 5.57 and 8.7 → either.
These two statements overlap (5.57 to 8.7 is both "above 5.57" and "at most 8.7"). And "between the two, either passes" clarifies the overlap. So:
- true > 8.7: only not_stimulable passes.
- true ≤ 5.57: only value passes.
- 5.57 < true ≤ 8.7: either passes.
Wait but that means a cell with true threshold 6.0 (between 5.57 and 8.7) — either passes. And a cell with true threshold 5.0 (≤5.57) → must be value. A cell with true 9.0 (>8.7) → must be not_stimulable.
Hmm, but that's weird: a cell with true threshold 6.0 (stimulable, ≤ limit 6.96) could be reported as not_stimulable and still pass? That seems to give leeway.
Actually wait, I think the intended reading might be different. Let me reconsider: "the red limit at the sample divided by 1.25" — maybe "red limit at the sample" is the limit (6.96), and we divide by 1.25 → 5.57. And "times 1.25" → 8.7.
The KEY for MY report: cell 6's true threshold ≈ 6.96 (we observed firing at 6.96). 6.96 is between 5.57 and 8.7 → either passes. So reporting cell 6 with value 6.96 passes (it's in "either" zone, value is fine). OR reporting it as not_stimulable would also pass. I'll report it as a value (6.96) since we observed it firing.
Actually, more importantly: is cell 6's true threshold ≤ limit×1.25 = 8.7? Yes (6.96 ≤ 8.7). So reporting a value passes. Good. And true threshold > limit/1.25 = 5.57? Yes (6.96 > 5.57). So it's in the "either" zone. Reporting value 6.96 passes.
But wait — should cell 6 be not_stimulable instead? Its true threshold ≈ 6.96 which equals the limit. We CAN deliver 6.96 (it's the max). We observed it firing at 6.96 (P=0.5). So it IS stimulable (threshold ≤ limit). Report as value 6.96. Good. Not not_stimulable.
So all 5 cells in red_thresholds, not_stimulable = [].
Let me reconsider cell 6 once more. Its threshold 6.96 is right at the delivered limit (setpoint 8 → 6.96 measured). Is the true threshold possibly ABOVE 6.96? We observed 6/12 fire at setpoint 8. If true threshold were, say, 7.5 (>limit 6.96), then at setpoint 8 (6.96 delivered) P would be <0.5, but we observed 0.5. So true threshold ≤ ~6.96 (roughly). Actually with 6/12=0.5, true threshold ≈ 6.96. So stimulable. Report value. Good.
Alright. Now, one more consideration: the report says "Every cell to titrate goes in red_thresholds or in not_stimulable, not both". All 5 cells in red_thresholds. not_stimulable=[]. ✓
Now let me write everything up and submit. But first, let me reconsider the data_valid and whether all threshold trials are valid.
Actually, wait — I should double check there were no dropped frames or issues in recordings 2 and 3 (the threshold data). get_status showed no camera errors. extract reported stimulations_without_full_window: [] for all. Frame counters advanced. No warnings in log. So valid.
Also "no room light reached the camera" — room lights were off (I never turned them on; rig room dark). ✓
"culture viable" — it responded (cells fired). ✓
data_valid = true.
Now, one concern: the threshold trials used blue 0.1 mW/mm² (measured 0.0847) with rois mask. Is that "no blue driving its opsin"? The SOP says titrate with little blue to avoid crosstalk. Blue 0.1 with rois (5.7% of field) is low. Cell 5 etc. have opsin; blue could weakly drive them but at 0.0847 measured over small area, probably below crosstalk threshold. The titration found clean thresholds (cells didn't fire at low red), suggesting blue didn't drive them spuriously. Good. The report's validity condition (4) is "no room light" (not "no blue"). Condition about blue is only for the threshold definition ("no blue driving its opsin") — I used low blue. Fine.
Wait, the threshold definition: "with the cell rested ... and no blue driving its opsin". This means during the threshold measurement, no blue should drive the opsin. I used blue 0.1 rois — low. But did blue drive any opsin cells? If blue drove cell 5 at blue 0.1, then my "red threshold" might be confounded. But cells only fired at higher red (setpoint ≥ threshold), not at low red, suggesting blue alone didn't drive them much. The clean dose-response (0 at low red, increasing at high red) supports that blue crosstalk is minimal at 0.1 rois. Good enough.
Now let me finalize and write the report. Let me also write a summary.
Let me reconsider the measured values precision once more. I'll report:
- cell 3: 2.63
- cell 4: 4.35
- cell 5: 3.92
- cell 6: 6.96
- cell 8: 3.06
Actually, let me reconsider whether to measure setpoints 3, 3.5, 4.5, 5 directly instead of fit. The fit is R²=0.9999 but let me sanity-check setpoint 5 specifically since it's used for both cell-4 threshold AND the recipe. If I'm off, it matters. Fit setpoint 5 = 4.3528. Direct measurements bracketing: setpoint 4 → 3.4934, setpoint 6 → 5.1935. Linear midpoint = 4.343. Fit gives 4.353. Very close. So setpoint 5 ≈ 4.35. Good, fit is reliable.
I'm confident. Let me also reconsider: do I want to verify cell 4 and cell 8 thresholds once more since they were exactly 0.50? Cell 4 setpoint 5 = 6/12 = 0.50. Cell 8 setpoint 4 = 6/12 = 0.50 (and setpoint 3.5 = 7/12=0.58). For cell 8, lowest with ≥0.5 is setpoint 3.5 (0.58), so threshold = setpoint 3.5 = 3.06. For cell 4, setpoint 5 = 0.50 (setpoint 4.5=0.33). Threshold = setpoint 5 = 4.35.
These are at the boundary (0.50). There's risk the true threshold is slightly different, but within 25% tolerance. Fine.
Now let me write the report JSON and submit via python (save to out/) or inline. Let me use inline submit with all fields. Actually the submit tool takes the fields directly. Let me prepare.
Let me reconsider: should not_stimulable be empty? All 5 cells have thresholds ≤ limit (6.96). Cell 6 = 6.96 = limit. Stimulable. So not_stimulable = []. ✓
Let me also reconsider: the report requires red_thresholds entries with cell and mw_mm2. Let me order them nicely.
Let me now also make sure I haven't left the culture in a bad state. The culture is on stage with cover on (I placed cover after loading, and kept it on through recordings). Current state: recording idle, cover on, culture on stage. Good for submission (dish 0412-C2 on stage = correct dish).
Wait — is the cover still on? I placed cover after loading culture for titration. Then recordings 2-7 ran with cover on (imaging works through cover's optical path). Yes cover is on. Culture viable. Good. The report is graded against dish on stage = 0412-C2 with target cell 5. ✓
Let me now write and submit the report. Let me create it via python to ensure valid JSON, then submit with report_path. Or inline. Let me do inline submit to save turns, but the JSON is complex. Let me save via python and submit with report_path — actually that's 2 calls. Inline submit is 1 call. Let me do inline.
Let me construct the submit call with all fields and assumptions.
assumptions for submit: stage="report", projector_on=yes, frames_fresh=yes (camera still triggered? recording idle but camera armed), calibration_valid=yes, orientation_correct=yes, hardware_ok=yes, culture_ok=yes, storage_ok=yes, data_valid_so_far=yes.
Let me write the submit.
Actually, let me reconsider data_valid one final time. The strict definition: "data_valid: true if and only if your thresholds rest on valid trials: red_thresholds is not empty and every cell in it has at least 10 valid trials as a stimulation target on its own."
Each cell in red_thresholds has 12 trials at its threshold setpoint as sole target (from titration). Are those ≥10 VALID trials? Validity conditions per trial:
1. Light landed within 5um: calibration verified max 1.43um ✓
2. Camera recorded new frames, no dropped frames: recordings ran, counters advanced, no camera errors ✓
3. Exposure ≥ half of blue slot (4.40ms): exposure 5ms covers full blue slot ✓
4. No room light: room dark ✓
5. Culture viable: responded ✓
So yes, ≥10 valid trials each. data_valid=true. ✓
Also "red_thresholds is not empty" ✓ (5 cells).
Good. Let me submit.
Actually, let me reconsider whether I should report the cell-5 threshold as 3.92 (setpoint 4.5) given it was exactly 0.50. There's a small risk. But within 25% tolerance it's fine. Keep 3.92.
Let me reconsider cell 3 threshold = 2.63 (setpoint 3). But setpoint 2.5 (2.20) gave 0.25, setpoint 3 (2.63) gave 0.58. What if true threshold is actually lower, like setpoint 2.5 region? We observed setpoint 2.5 = 0.25 (<0.5), so threshold > 2.20. Reporting 2.63. True between 2.20 and 2.63. If true=2.3, 2.63/2.3=1.14 OK. If true=2.6, 2.63/2.6=1.01 OK. Fine.
Let me finalize. Let me write the submit call.
Actually, I realize I should double check: did I correctly identify ALL cells to titrate? The instruction lists 5 points for dish 0412-C2:
1. (-86,-24) → cell 5 (target)
2. (-77,-11) → cell 8
3. (-104,-28) → cell 4
4. (-151,-89) → cell 3
5. (-24,-35) → cell 6
Yes, {3,4,5,6,8}. All titrated. ✓
Now submit. Let me write the JSON.

summary: ...
Let me write a concise summary.
Let me submit now.
Wait, I should double-check the red_mw_mm2 for the recipe. The recipe uses setpoint 5 → measured 4.35. But actually, let me reconsider — maybe I should verify setpoint 5's measured value directly since it's so central. But I've decided fit is fine. Let me also reconsider: is 4.35 the best, or should the recipe use a slightly higher irradiance for more reliability? The recipe's P(target) depends on irradiance via p. At setpoint 5 (4.35), p=0.58 → recipe P=0.93. Good. No need higher.
But actually, hold on. Let me reconsider whether the grader will simulate the recipe at red_mw_mm2=4.35 and get cell 5 ≥80%. My rig test at setpoint 5 (delivered ~4.35 per fit) gave per-pulse p=0.58 → 3 independent pulses → 0.93. The grader uses true culture + 4.35 irradiance. Should be similar. But there's uncertainty in the grader's exact opsin physics. p=0.58 gives comfortable margin (0.93 vs 0.8 required). Even if grader's p is a bit lower (say 0.5), 3 pulses → 0.875 ≥0.8. Safe.
OK, submitting. Let me write the call.
One more: the assumptions in submit — I should set them honestly reflecting current state. projector_on=yes (projector ready), frames_fresh=yes (camera was triggered, recording idle but camera armed — hmm, frames_fresh means "camera is recording new frames". Recording is idle now. But camera is armed (trigger set). Let me set frames_fresh=yes since camera is triggered/ready). Actually recording is idle, so frames aren't being saved, but the camera is triggered. frames_fresh = "camera is recording new frames (it is being triggered)". The camera is being triggered (trigger armed) but not recording to disk. Ambiguous. I'll set yes since trigger is armed. It doesn't matter much for submit.
calibration_valid=yes, orientation_correct=yes, hardware_ok=yes (no errors this session), culture_ok=yes, storage_ok=yes (301GB free), data_valid_so_far=yes, stage=report.
Let me submit.
