2019-20 Spectra

• G-001 cardboardconnection.com and checklistcenter.com both state the base set is "175 cards," but their own text shows this figure folds in the separately-named 25-card "Spectracular Performances" insert (cards 151-175); tcdb.com tags cards 151+ with a distinct "PERF" designation, and Panini's own blog (blog.paniniamerica.net) describes the base short-print variation checklist as spanning only cards #3-#150. Recorded base_set_size=150 with Spectracular Performances as a separate insert set; the 175 figure is an unresolved editorial disagreement.
• G-002 No source (cardboardconnection.com, checklistcenter.com, beckett.com, blog.paniniamerica.net) states an explicit print run for the Silver base parallel. Recorded as unnumbered based on absence of a stated number, not an explicit confirmation.
• G-003 Release date recorded as 2020-07-01 (cardboardconnection.com, tcdb.com, steelcitycollectibles.com, dacardworld.com agree). However blog.paniniamerica.net's "Detailed First Look" preview post is dated 2020-05-06 and checklistcenter.com states 2020-06-26; these are likely announcement/estimated-ship dates superseded by the actual 2020-07-01 hobby release, but this is not independently confirmed.
• G-004 rookie_flag=yes for cards 101-150 is based on checklistcenter.com's explicit "Rookies" section label for that exact number range, corroborated by an explicit "RC" tag seen on sampled rows 109, 148, 149 and 150 on tcdb.com. Not every individual card in the range was checked for an explicit RC tag.
• G-005 tcdb.com tags most Rookie Jersey Autographs cards SN149 (matching checklistcenter.com's stated #/149) but tags card 181 (Zion Williamson) SN60. This per-card print-run exception is single-source (tcdb.com only) and unconfirmed elsewhere.
• G-006 No numeric pull-odds sheet was located anywhere for this product (checked blog.paniniamerica.net sell sheet PDF, cardboardconnection.com, checklistcenter.com, blowoutcards.com, dacardworld.com, steelcitycollectibles.com) - consistent with Panini not publishing numeric odds sheets for basketball. All stated_odds fields left blank.
• G-007 No editorial or manufacturer source uses case-hit/SSP/short-print tier language for any BASE-set color parallel (Silver, Celestial, Interstellar, Meta, Gold, Universal Die-Cut, Marble, Nebula) beyond bare print run numbers already in parallels.csv. Per the anti-fabrication rule against inferring tier from print run alone, scarcity_parallels.csv was left empty rather than guessing.
• G-010 The 25 Base Variations rows are written with tcdb's "b" tokens (3b ... 150b) exactly as https://www.tcdb.com/Errors.cfm/sid/227002/2019-20-Panini-Spectra renders them. It is NOT established that "b" is a character printed on the card: tcdb uses it to disambiguate a variation sharing a base card's number, and other catalogues use different forms for the same cards. The token is written verbatim and not stripped, but it should not be asserted as the printed number. The variation itself is evidenced per row (e.g. "VAR: White Jersey", "VAR: Facing Left"). Count and split corroborated by blog.paniniamerica.net (13 veterans / 12 rookies), which matches the token ranges 3b-97b and 101b-150b exactly.
• G-011 All five Rookie Dual Patch Autographs cards carry TWO signers on one card. tcdb renders both players and both teams in the respective columns (https://www.tcdb.com/ViewSet.cfm/sid/236765/2019-20-Panini-Spectra-Rookie-Dual-Patch-Autographs), e.g. "RDP-JR | Ja Morant / RJ Barrett | Memphis Grizzlies / New York Knicks". Written verbatim as the source renders the pair, so player_name and team_or_school each hold two values separated by " / ". These are 5 cards, not 10; do not split them into separate rows. Consumers keying on a single player or a single NBA team will need to parse the pair.
• G-013 sets.csv's note for Rookie Jersey Autographs names seven parallel tiers (Interstellar, Celestial, Meta, Marble, Nebula Logoman, Wave FOTL, Gold Wave FOTL) and parallels.csv carries seven rows. tcdb's https://www.tcdb.com/Inserts.cfm/sid/227002/2019-20-Panini-Spectra lists only THREE Rookie Jersey Autographs sids (Gold Wave FOTL 236769, Nebula Logoman 236770, Wave FOTL 236771). The likely explanation is that the Interstellar/Celestial/Meta/Marble tiers for this set are filed under the BASE parallel sids rather than under a Rookie-Jersey-Autographs-specific sid, since the set itself lives inside the parent checklist (G-009) - the Celestial base parallel sid 236713 reports Total Cards 242, which spans the full 1-217 range plus variations, whereas Universal Die Cut sid 236720 reports 200 and therefore stops at 175. NOT CONFIRMED card-by-card; no file was edited. Flagged so a parallels pass does not read tcdb's three sids as evidence that the other four tiers do not exist.
• G-015 The 25 pre-existing Color Blast rows carry a source DESCRIPTION in notes ("checklistcenter.com full-checklist listing...", "corroborated by Goldin, GoCollect, eBay(BGS) and SteelCityCollectibles") but NO full https:// URL, which is the format the shared spec requires on every row and names as the project's most repeated output failure. Those rows were not in this pass's scope and were left byte-identical, per the append-only instruction. Flagged for a later citation-repair pass; tcdb carries the set at https://www.tcdb.com/ViewSet.cfm/sid/236731/2019-20-Panini-Spectra-Color-Blast if a resolvable primary citation is wanted. Separately: checklistcenter.com is on the spec's roster-only list (never a card_number source) and Color Blast is a plain 1-25 insert rather than a coded set, so the numbers are likely sound - but the four marketplace corroborations named in those notes are not resolvable as written.
