# Research notes

## Sources and access
Eighteen useful sources were inspected, including five distinct original outputs. Visual objects are not independent corroboration of metadata. Read the official collection, artist project and about pages, substantive feature guide, print documentation and out-of-band generator instructions. The complete feature guide was recovered through direct HTTP after a web 429 response. Print and out-of-band pages also succeeded through HTTP after web failures.

The contemporary Portuguese bulletin was read through the web tool; a later HTTP 403 did not negate the successful body inspection. Its linked Twitter announcement failed and is not cited. Unrelated same-title game licences were excluded. Marketplace and price-aggregator snippets were not used as historical evidence.

## Full script inspection
The complete 8,596-byte indexed script was read: setup, draw, class P constructor/run/stack/pattern/edge/show, recursive sd, noise helper sn, sp, gp, sa, re, ch, mr, dk, Uint32 seed, R and remaining helpers. The exact SHA-256 is in record and evidence. Four 32-bit states come from the first 128 hash bits; noise uses the first state. Ground and facade subdivision, projected quadrilaterals, bending, width changes, stacking and fog were traced through their actual drawing operations.

The draw function processes 25 entries per cycle in an offscreen buffer. It copies the finished image to the visible canvas after completion and calls noLoop. No audio, input or external-media calls occur in the artist code. Official original renderers were viewed; no local reconstruction was executed. Raw code remains only in the ignored sibling checkpoint. Retrieval was indexed, not a block-pinned chain extraction.

## Token identity and visual observation
Five exact token records were retrieved and their canonical pages returned 200. Originals 0, 1, 10, 20 and 590 were viewed in isolated Chrome. Edition one initially appeared blank and later showed its completed city. Edition 590 remained unchanged across observations 23.029 seconds apart; its official 2,400-by-2,400 preview was also viewed. No continuous animation or interaction was inferred from third-party listings. Out-of-band controls were read but not executed, and were not attributed to the token script. Mobile compatibility was not tested; no audible-playback claim is made.

## Header ownership and media
The freshly retrieved AB5D linked-wallet set matches the indexed owner of edition 590. Source, query and time appear in presentation.json. The static preview recommendation is subject to resolution of the licence version and public display basis. No media is redistributed, and no artificial loop is proposed.

## Mint chronology and calculations
All 676 indexed records fall on July 28, 2021. First token: 00:47:37 UTC. Activation: 02:48:30 UTC. Final mint: 19:01:11 UTC. Edition one at 17:45:12 through edition 675 gives 4,559 seconds, or 75 minutes 59 seconds.

The contemporary bulletin reports 16:00 BRT, equivalent to 19:00 UTC, with 675 units at 0.15 ETH. There are 234 indexed tokens before that time. Edition 233 is at 18:59:57; edition 234 is at 19:00:03. Seventy-one seconds after the reported schedule must not be presented as a verified public sellout interval. Whether 675 excludes edition zero is a hypothesis, not an established allocation policy.

Two inspected single-token mint transactions, for editions one and 675, each carry 0.15 ETH, excluding gas. The explorer's decoded parameter name was not trusted as ABI semantics: argument 0x77 is project number 119, not the payment amount. The complete pricing history was not audited. Donation completion is artist-reported; recipient receipts were not verified.

## Rights and conflicts
The exact label is CC BY-NC-SA, without a version or link. CC BY-NC-SA 4.0 legal terms were inspected as a candidate only. No licence was borrowed from an unrelated game bearing the same title. Public display remains pending version review. Artist-code permission and the grant covering the credited Piter Pasma generator remain unknown. The p5 LGPL 2.1 licence is separate. CC0 applies only to the essay's original prose.

## Unresolved questions and exceptions
- Original cap, announcement and allocation records explaining the 675/676 difference and early mints.
- Complete pricing history.
- Operative artwork licence version, public display basis and code permissions.
- Donation receipts.
- Dated prototypes.
- Measured usage.

All exceptions remain pending, not accepted.

## Actual model, tools, elapsed time and measured usage
OpenAI gpt-6-astra; Python urllib, web.run, CUA Chrome and local structural validator. Retrieval and cutoff timestamps are retained. A precise elapsed research timer was unavailable; no duration was estimated. Token counters remain null for coordinator measurement. Phil commissioned the research; human review is pending. This is a seven-file isolated draft, with no shared files, build, git or publication changes.
