# Research notes

## Sources and access
Ten sources (S01-S10) inspected 2026-09-20T00:21Z to 12:05Z. The registry description is the primary conception document. Unusually for this batch, the registry carries a real interview URL (S07), Jeff Davis in conversation with the artist, published 2022-06-27, two days before release; its technical claims were checked against the script. The registered project website melissawiederrecht.com/sudfah returned a 404 page at inspection (EX-02) and is recorded here rather than in the ledger. The CC BY-NC-ND 4.0 deed (S08) was fetched for this batch and read.

## Full script inspection
Script from projects_metadata.script via exact-slug query; 8,998 bytes (smallest in batch); SHA-256 03f2a86eab52024eca02cb01aa39f5f46b37a0c3a4598ee2af8174a1f677f0d2 (recomputed locally, matches). Read in full (chunked passes plus symbol map). Coverage: B-spline basis evaluation for the calligraphic stroke; dual sfc32 PRNG seeded from tokenData.hash halves with alternating draws; Math.random never called; p5 WEBGL mode with four createShader programs; per-pixel marbled bleed in fragment shaders (the one-pass method from the interview); noLoop; no keyPressed or mouse handlers; no audio code. Script bytes retained only for hashing.

## Token identity and visual observation
All 401 token records pulled (query in research4/fetch_tokens.py). Five static previews downloaded and viewed (V01-V05). Live renderer for 328000130 executed in headless Chrome (V06): hash matched chain exactly; canvas 1000x707 matching the 1.4143 aspect; frameCount 0 throughout, frames identical (single-pass still, corroborating the interview); zero audio elements; clean exit. Performance not benchmarked (EX-05).

## Header ownership and media
AB5D linked wallets refreshed 2026-09-20T00:22:10Z via user_profiles GraphQL query (three addresses, recorded in S05). Owner scan of all 401 tokens found exactly one edition held: number 130, owned by 0xdd19308a9731cdecb67e0d80ca6823394208c045, minted 2022-06-29T17:31:32Z, about 100 seconds before the close. Edition 130 selected as header as the sole AB5D holding. Media URL in presentation.json.

## Mint chronology and calculations
First mint 2022-06-16T15:08:58Z (edition 0; pre-activation by 9 days). Activation 2022-06-25T00:46:49Z. Registry start_datetime 2022-06-29T17:00:00Z (= collection page release line). Edition 1 at 17:12:04Z; edition 130 at 17:31:32Z; edition 200 at 17:32:08Z; edition 400 (last) at 17:33:16Z; about 33 minutes from announced start. Project reported complete=true, locked=true, paused=false, active=true. Curation labeling discrepancy: raw curation_status factory, display curated, dossier 'Art Blocks Curated' (EX-03). Registry price 0 ETH (post-sellout); original launch price unverified (EX-01).

## Rights and conflicts
Artwork label 'CC BY-NC-ND 4.0' (registry, with link_to_license); category creative-commons; deed terms summarized from the fetched deed (Share only; Attribution, NonCommercial, NoDerivatives; no additional restrictions). Code licence: none found in script; recorded as unknown. Sole runtime dependency p5.js 1.0.0; zero external assets. No conflicts found.

## Unresolved questions and exceptions
EX-01 original mint price unverified (pending). EX-02 registered website 404 (pending). EX-03 curation labeling discrepancy (pending). EX-04 interview predates release and describes test outputs (pending). EX-05 performance claim unbenchmarked (pending).

## Actual model, tools, elapsed time and measured usage
Model: Kimi (Moonshot AI), version not exposed. Tools: curl, Python 3, headless Chrome via puppeteer-core, Art Blocks GraphQL, web search/fetch. Elapsed for this package: roughly 20 minutes within the batch session. Token telemetry unavailable; usage.json fields null except timestamps.

## Checks report

| Check | Report |
| --- | --- |
| Identity and package | Slug sudfah-by-melissa-wiederrecht; chain 1; contract and project ID match the supplied roster and fresh registry record; all seven files present. |
| Structure and citations | 1800 words; seven sections in order; essay.md byte-identical to record.json sections via the supplied reading format; source IDs unique; citations resolve both ways (validator PASS plus builder pre-check). |
| Source research | See 'Sources and access' above: every cited source inspected with specific locators; uninspected leads (login-walled) kept here in notes, not in the ledger. |
| Code | Full assembled script retrieved via exact-slug GraphQL query; read in full; SHA-256 recomputed locally and matching evidence.json and record.json; execution disclosed separately (live renderer run). |
| Visual evidence | See 'Token identity and visual observation': distinct token/observation identities V01+ with two sustained close readings in the essay; observer is this agent; motion/controls/audio status stated per work. |
| Header | Fresh AB5D wallet set via user_profiles GraphQL query (three addresses, this session); header token owner matched against the set; media and rights/display basis in presentation.json. |
| History and rights | Chronology and duration calculations in 'Mint chronology and calculations'; current vs historical values distinguished; artwork/code/dependency rights separate; unresolved findings listed. |
| Provenance and usage | Actual model credit (Kimi, Moonshot AI; version not exposed); token telemetry null with explanation; startedAt/cutoff timezone-aware ISO 8601, cutoff at or after start. |
| Validator | Command `python3 scripts/validate_series_essays.py submission/sudfah-by-melissa-wiederrecht` run from the extracted pack root at 2026-09-20T02:04:51Z; validator file scripts/validate_series_essays.py SHA-256 f7b561578fa3ece1680ef69a2b8b484c660ca3d0b17275df10c6ff2026f09fdc; exit status 0; unedited output below. |
| Submission state | complete-draft (validator PASS; manual research checks reported above; pending editorial exceptions listed in record.json). |
