## Method notes Twenty `speaker_N` labels carry substantial speech in this transcript; the remaining 95 sparse labels (of 115 total) are merged into `` by the diarization pipeline and are out of scope for this roster. **Two voices account for most of the fragmentation.** The presiding chair (`speaker_0`/`speaker_1`/`speaker_2`/`speaker_367`, 25 segments total) and the mayor (`speaker_66`/`speaker_68`/`speaker_70`, 30 segments total) are each one continuous person split repeatedly across labels — visible where a sentence starts under one label and finishes, mid-word, under another (e.g. the mayor's "That money's" [t=676] / "coming in." [t=689]). Each fragment is merged via `merge_with`, keeping the original label ids so the merge is undoable. **The mayor is never self-identified in this transcript.** "Brandon Sakbun" is carried forward from this vault's prior meetings (2026-04-09, 2026-06-11, 2026-07-09), where residents named him directly (if with garbled transcriptions — "Sackbun," "Sackman") and where `Ledger/Entities/People/` does not yet hold a formal entity for him. He is graded `probable` here specifically because *this* transcript supplies no independent naming event — only role (giving "communications for the mayor") and cross-meeting identity continuity. No `Ledger/Entities/People/brandon-sakbun.md` exists yet; creating one is a natural follow-up once the thread stage runs. **One contaminated cluster.** `speaker_348` (Street Department, Resolution 11-2026) is addressed as both "Brian" and "Jesse" at different points in what reads as one continuous voice. Rather than pick the more frequent or more recent name, it is left `role_only` — the standard's explicit guidance for contradictory evidence under one label. **Staff identified by first name only.** The Fire Chief presenting the support-truck purchase (`speaker_137`) is addressed once as "Bobby," with no surname recoverable anywhere in the transcript — graded `probable`, not `confirmed`, on that single naming event. **No `[t=]`-quoted basis in this roster attributes a motion-making or vote-casting act to a name graded below `confirmed`.** Where the chair (graded `probable`) narrates who moved or seconded a motion, the named mover/seconder is independently graded above under their own label wherever one of the 20 substantial labels captures them speaking; where it doesn't (e.g. Azar, who moves/seconds several times per the chair's narration but has no directly tagged substantial label in this transcript), no entry is fabricated for them here. **Unresolvable by design.** `agenda_unavailable` is set on this meeting — the agenda PDF has no extractable text — so nothing here can be cross-checked against a printed roll or item list. Verification should be repeated once the agenda is OCR'd or minutes are published. **Open questions for the audit pass:** 1. Confirm "Anthony J. Dinkel" as presiding Council President this meeting — the only in-transcript naming event ("Council President Dinkle" [t=578]) is on an untagged segment adjacent to, not inside, the merged chair labels. 2. Confirm "Brandon Sakbun" against the agenda/minutes once OCR'd, and create `Ledger/Entities/People/brandon-sakbun.md` if not already pending from another meeting's thread stage. 3. Fire Chief's surname ("Bobby ___") and the Street Department staffer's actual name ("Brian" vs. "Jesse") are both unresolved. 4. `speaker_98` and `speaker_101` are both plausibly Clerk-office staff but show stylistically distinct content (procedural item-reading vs. statutory explanation); left as separate labels rather than merged on a guess.
