Sensitivity registry for PolicyEngine microsim results — maps {program x deviation signature} to the calibration target or imputed variable most likely driving a mismatch, and reads the live per-target diagnostics for the current Microcosm release. The knowledge base behind the calibration-diagnostics agent and /analyze-policy Stage 5.6. Load when investigating why a microsim result differs from a prior score, or when reviewing whether a reform classification is calibration-sensitive.

PolicyEngine calibration diagnostics
Converts tribal "I'd check the takeup rate first" knowledge into a structured sensitivity
registry, and pairs it with the live per-target calibration API so hypotheses are ranked against
real relative_error numbers rather than assumptions. When an /analyze-policy comparison
returns INVESTIGATE, this skill supplies the ranked candidate causes.
The calibrated microdata is now a Microcosm build (see the policyengine-data skill for how
targets, weights, and L0 sparsity work). Calibration targets live in the Microcosm build's target
set — not in a hand-maintained loss file — and their fit is queryable per release from the
dashboard API below.
When to use
- Stage 5.6 / Stage 6 of
/analyze-policy— invoked by thecalibration-diagnosticsagent. - Code review of microsim PRs where the headline number differs from priors.
- Designing or auditing a Microcosm calibration target.
- Debugging why a state-level run looks volatile.
Top-level architecture
PolicyEngine microsim results depend on three layers:
- Country model logic (policyengine-us, policyengine-uk, policyengine-canada) — formulas, parameters.
- Calibrated microdata (Microcosm) — survey weights + imputations matched to administrative targets.
- Behavioral assumptions (takeup rates, labor-supply elasticities) — usually parameters but easy to overlook.
A magnitude mismatch is almost always rooted in layer 2 or 3, not layer 1 (layer-1 mismatches show up as outright simulation errors, not magnitude drift).
Live calibration API (check this first)
Per-target fit for the current Microcosm release, no auth, reads the release from Hugging Face:
BASE = https://calibration-diagnostics.vercel.app/calibration/dashboard/api/populace
GET {BASE}/target-diagnostics?source=<source> # every target for a source, with relative_error
GET {BASE}/target-investigation?target=<id> # full investigation packet for one target
GET {BASE}/releases # release ids for pinning
Sources map to reform domains: Social Security → ssa; Medicaid/ACA/Medicare →
cms_medicaid / cms_aca / cms_medicare; TANF → hhs_acf_tanf; income tax / credits →
irs_soi, jct, cbo; state income tax → state_income_*. A target already >10% off in the
release diagnostics is a stronger hypothesis than any prior. (Dashboard UI:
calibration-diagnostics.vercel.app.)
The three-ring reading method (align with /analyze-policy Stage 5.6)
Checking only the reform's primary marginal is the classic miss — a reform's cost usually depends on the joint distribution of its variable with other income, and the primary marginal can calibrate perfectly while the interaction is off. Check three rings outward:
- Ring 1 — the primary variable's marginals. Map the reform's domain to a calibration source and fetch its targets.
- Ring 2 — the mechanism's other inputs. Every variable that enters the formula the reform
changes. SS-benefit taxation depends on combined income, so dividends, taxable interest, and
pensions (
irs_soi) are load-bearing; a CTC phase-in depends on earnings; a SNAP change on rents and deductions. - Ring 3 — the interacted quantity itself (best single check). Search for the downstream
quantity the reform directly reprices —
taxable_social_security_amountfor SS-taxation,eitc_amountfor EITC, itemizer counts for deduction caps. When such a target exists it validates the joint distribution end-to-end through the actual formula, and itsrelative_errorbounds the data-side bias of the score. Weight it above every marginal. When no ring-3 target exists, say so — "marginals within tolerance; joint distribution untargeted" is materially weaker evidence.
Worked example (HR 904, SS-taxation reform): ssa total benefits calibrate to −0.2% (ring 1 fine)
while irs_soi ... taxable_social_security_amount runs −10.9% (ring 3) — the score's operative
base is ~11% low in the data even though the headline marginal is nearly exact.
Interpretation is informative, not a gate: a poorly-calibrated but reform-relevant target does
not flip the comparator verdict by itself, but it belongs in the report's uncertainty discussion.
Escalate to INVESTIGATE when a directly-load-bearing target (the primary variable OR the ring-3
interacted quantity) is off by |relative_error| > 25%, even if headline numbers match anchors.
Sensitivity table — top programs
The rows below are the paradigm-independent knowledge: which calibration input moves which result, and in which direction. They hold regardless of which build produced the weights — use them to decide which targets to pull from the API above.
EITC
| Calibration input | Direction of effect | Notes |
|---|---|---|
| Childless-adult takeup rate | Higher → more cost, more poverty reduction in deciles 1-3 | Historically ~65% childless vs ~80% with-kids. Uniform-takeup models over-state expansions. Verify against gov/irs/credits/eitc/takeup.yaml if present. |
| Earnings distribution in $5K-$15K band | More density → more phase-in/plateau beneficiaries | PUF→CPS imputation is sparse for childless filers here. |
| Tax-unit definition for cohabiting adults | More split units → more eligible filers | Check tax_unit_count calibration vs SOI Table 1.1. |
| Age cohort 19-24 workers | Newly eligible under ARPA-style age expansion | Not separately calibrated; marginal population sits under the generic young-adult bucket. |
| Age cohort 65+ workers | Eligible under ARPA age-cap removal | Drives meaningful senior poverty reduction (e.g. −5% in a live EITC test). 65+ earners with $5-15K earned income are NOT a separately calibrated population; expect higher variance. |
| Known issue | github.com/PolicyEngine/policyengine-us/issues/4276 — total EITC over-estimate ~9% vs CBO |
EITC coverage note: thinner than the CTC and SALT rows. The diagnostics agent should emit
coverage_note: "EITC row is partial; hypotheses cover takeup and age-cohort but NOT joint-filer marriage-penalty mechanics, investment-income-limit interactions, or self-employment-income imputation. If your deviation signature touches any of these, widen the confidence band."
CTC
| Calibration input | Direction of effect | Notes |
|---|---|---|
| Non-filer CTC takeup | Higher → much more poverty reduction (largest lever) | ARPA achieved ~90%+ via IRS portal; non-ARPA defaults ~75%. |
| Imputed child age distribution (0-5 vs 6-17) | More 0-5 → more cost (the $3,600 tier) | Compare imputed age-0-5 share to ACS published by single year of age. |
| Non-filer share | Higher → more refundability benefit | CPS undercounts non-filers; addressed via PUF imputation. |
| EITC interaction (refundable ordering) | Incorrect ordering → double-count | Check irs_credits_ordering parameter. |
| SPM threshold + state benefit offsets | State-specific | Few states tax CTC; SSI supplements vary. |
SALT cap
| Calibration input | Direction of effect | Notes |
|---|---|---|
| Itemizer share | Higher → cost balloons, benefit cascades down deciles | Post-TCJA only ~10% itemize. Track the itemized-deduction / SALT calibration target via irs_soi in the live diagnostics. |
| State income tax imputation | Flat (federal-AGI-driven) → regressive signature disappears | High earners in NY/NJ/CA drive the SALT story. |
| Top-1% AGI calibration | Under-weighted → top-decile concentration compresses | Targeted via SOI Table 1.1 AGI bands. |
| AMT interaction | Missing → over-states upper-middle benefit | Pre-TCJA AMT clawed back much SALT. |
State income tax (any state)
| Calibration input | Direction of effect | Notes |
|---|---|---|
| State weights from CPS | Small state → high variance | RI has ~3-4k records; CA has ~50k. Relative uncertainty scales inversely. |
| State-AGI tail imputation | High-income tail mis-calibrated for some states | Affects progressive brackets disproportionately. |
| Federal conformity | Outdated assumption → cascading error | Check gov.states.{state}.tax.income.conformity.* if present. |
Refundable credits broadly
| Calibration input | Direction of effect | Notes |
|---|---|---|
| Non-filer share | Higher → more refundability benefit | CPS undercounts; PUF imputation step matters. |
| Takeup rate by income | Defaults often uniform | Real-world takeup varies; mis-spec biases low-income impact. |
Deviation signature playbook
| Signature | Top hypothesis | Test to run |
|---|---|---|
| Cost too high, benefit too even across deciles | Itemizer share or state-tax imputation flat | Perturb itemizer share −10%; rerun. |
| Cost roughly right, poverty impact understates by ≥30% | Non-filer takeup or SPM unit definition | Set takeup = 0.95; rerun. |
| Small-state cost volatile vs prior | State CPS weight variance | Bootstrap state weights, report CI. |
| Top-decile benefit share too low | Top-AGI under-weighted | Cross-check AGI by SOI band. |
| Reform-vs-baseline difference flat across years | Uprating index mis-set | Verify uprating.* parameters. |
| Reform touching an untargeted variable scores ~$0 | Operative base pruned by L0 sparsity | Check if the base is a calibration target; if not, try a denser build (see policyengine-data). |

# PolicyEngine calibration diagnostics
Converts tribal "I'd check the takeup rate first" knowledge into a structured sensitivity
