Do the location clues hold up?

The wider check covers 108 large parent groups, 63 standard-clue pools and 1,481 target comparisons. It evaluates 91,827 wrong-guess states for the final proposed anchors. Alternative-anchor trials are additional.

Of 479 initial potential split proposals, 41 can leave five or more candidates in the wider comparison. A finer recorded location rescues 29 of them: 467 proposals finish below five in every tested reaching state; 12 retain five-plus states. These are target/clue proposals, not counts of unique dinosaur groups.

Five previously unresolved Baruungoyot proposals are also checked, making 17 crowded proposals across the full pool review. The approved roster policy now uses only Shuvuuia (66043), holding out duplicate spelling record Shuuvuia (307772). Both raw records are preserved. Five documented Baruungoyot matches remain. If exactly five established matches remain and the player guesses one of those five incorrectly, only four remain. An outside guess need not remove one of the five. The count alone does not establish a need for free help.

These are catalogue and source-tree diagnostics, not scientifically approved gameplay clues. Pool comparisons assume all three provisional standard clues have been revealed; large-parent comparisons apply no standard-clue filter. The frozen source tree and incomplete standard facts still need review before Expert mode. Catalogue non-matches are provisional, not proof of fossil absence. Identity holds and exact-record amendments are documented in the complete locality review. This diagnostic does not itself activate an expanded live roster or new automatic-help trigger.

Completed decisions and remaining uncertainty

The complete follow-up has reviewed all 30 proposals remaining under policy v9 and all 26 shared cases in the original dossier. Read complete-locality-review.html for each decision, exact amendments, source access and remaining uncertainty.

Six further identity holds, missing positive profiles and exact Hekou/Yanan/Nanxiong corrections are now applied to the expansion audit. Pellegrinisaurus retains Allen and qualified Anacleto alternatives. Kirtland/Ojo Alamo and Qijianglong’s conflicting horizons remain explicit. Real Lujiatun and Shaximiao overlap is preserved; narrower type sites are not exclusive genus ranges.

Unverified originals and incomplete specimen inventories remain pending hidden-answer eligibility. Where informative tree probes and ordinary clues still cannot distinguish at least five unguessed answers, provide free help. This is a gameplay design requirement, not a new expanded-roster runtime hint.

Gastonia’s Poison Strip and Yellow Cat identity-review comparisons remain preserved as historical checkpoints. Qualified records and missing metadata continue to be retained in current comparisons.

How the check works

Every recommendation in all 108 large groups and all 63 matching pools is checked, including unresolved proposals.
Candidate sets include descendants and genera with missing standard evidence, wherever still consistent with the full provisional standard clues. Large-parent comparisons apply no standard-clue filter.
Every wrong source-roster guess reaching the target’s direct parent is enumerated, with the resulting relationship applied and the actual guessed genus removed.
If the original proposed anchor leaves five or more, every other recorded anchor for that target is also checked. A narrower alternative is reported where it keeps all reaching states below five.
Known non-primary occurrences, qualified identifications and relevant missing locality metadata remain possible. Supported horizon alternatives are retained.
These are source-tree diagnostics with all three provisional standard clues revealed. They do not simulate the unapproved Expert working tree, every multi-guess history, or unrequested clues.
Further guesses can only reduce these candidate sets. A five-plus count is not itself an automatic-help trigger: remaining tree branches or unresolved standard clues may still distinguish candidates.
No source-screen result establishes exhaustive fossil absence. Every proposed gameplay clue still needs scientific evidence approval; this check introduces no additional exclusions beyond the approved roster policy.
