Method notes

Fifteen speaker_N labels carry substantial speech in this transcript; 22 sparse labels (of 37 total) are merged into <other> by the diarization pipeline and are out of scope for this roster.

Three voices account for most of the fragmentation, matching this vault's recurring pattern across every prior Terre Haute City Council roster:

• The presiding chair, Anthony J. Dinkel (speaker_0/speaker_14/speaker_56).
• The clerk, Michelle L. Edwards (speaker_4/speaker_40/speaker_41).
• The city engineer, Marcus Meyer (speaker_48/speaker_51) — self-identified by full name for the first time in this vault's transcripts, resolving the "Marcus, surname unrecoverable" open question left by the 2026-09-03 roster.

All nine sitting council members are named in the roll call as present (Azar, Boland, Chalos, DeBaun, Dinkel, Hinton, Loudermilk, Nation, Thompson — [t=10]), under this transcript's own ASR manglings: "Bowen" for Boland, "Devon" for DeBaun, "Dingle" for Dinkel, "Launamilk"/"Laudamilz" for Loudermilk. Canonical spellings are taken from Ledger/Entities/People/, per this vault's standing convention. Only Dinkel, DeBaun, Nation and Chalos spoke enough to receive one of the fifteen substantial-speech labels above; Azar, Boland, Hinton, Loudermilk and Thompson are audible only inside the merged <other> bucket (seconding motions, brief remarks) and are out of scope for this roster.

Two of the councilperson identifications rest on a single post-hoc naming event (Chalos as seconder, speaker_99; DeBaun and Nation as movers, speaker_120/speaker_100) — the chair restating who moved and seconded immediately after the motion, rather than naming the speaker before they spoke. None of these labels casts a per-member roll-call vote or makes an accusation, so grading them probable does not run afoul of the hard limit in §12b.

One contaminated/ambiguous cluster: speaker_118. Its single occurrence reads as two different people's lines run together (a chair-style prompt and a one-word answer). Left role_only per this vault's standing guidance for contradictory evidence rather than guessing which reading is right.

No [t=]-quoted basis in this roster attributes a per-member vote or an accusation to a name graded below confirmed.

Open questions for the audit pass

1. Confirm "Marcus Meyer" as the city engineer's full name against an agenda or staff directory once one becomes available for this meeting (none was at ingest time — agenda_unavailable) — this roster's self-identification evidence is currently the only source, and no Ledger/Entities/People/ entity yet exists for him.
2. speaker_118's identity is unresolved — possibly the chair prompting Councilperson DeBaun, possibly a merged two-speaker turn. Left role_only by design.
3. Confirm whether speaker_62/speaker_74 (Nation, on the General Ordinance 10-2026 "take action" motion and Q&A) and speaker_100 (Nation, on the formal approval motion) are the same diarization-fragmented voice once a sharper transcript or the video is available; left unmerged here for lack of a direct splice between the two clusters.
