SGA Online Scheduling Coverage

Two paths — pick both

Path A · Engineering (zero code)

67 practices already running SGA-stack vendors

Neurality (53), TrueLark (8), and Modento (6) widgets are live on these sites today. The OSA catalog says "none" because nobody patched it. Existing scrapers already cover all three vendors — only a metadata backfill is required.

Path B · Marketing / Ops

73 practices with no online booking at all

No widget detected on any of 13 candidate URL paths. At a conservative 3 new patients per month × $1,200 LTV per practice, this cohort represents ~$3.15M/yr of unrealised new-patient demand. Marketing/ops decision, not engineering.

SGA-stack catalog patches

These 67 practices have a detectable Modento, Neurality, or TrueLark widget live on their public site today. The OSA catalog currently lists them as platform=none or absent. Patch the catalog → existing scrapers light them up immediately.

How the scan worked

URL resolution. Three sources: (1) OM-email-derived domains from the SGA Location Mapping xlsx (157 OM emails parsed), (2) umbrella-site scrapes (mydentalpartners.com, sgadental.com, modisdental.com, yourmagnoliasmile.com, coastaljaw.com, missloudental.com, etc.), (3) targeted web search with practice name + city + state for the long tail. 148 of 239 practices resolved to a fetchable URL; the other 91 are listed as unresolvable for ops.
Page fetch. Node 18 native fetch over 13 candidate paths per host: /, /book, /booking, /book-online, /book-appointment, /appointments, /appointment, /schedule, /schedule-online, /contact, /contact-us, /new-patients, /new-patient. 12-second timeout, 600KB body cap, 8 concurrent workers, 0.8s pacing between practices.
Signature matching. 26-vendor pattern dictionary (vendor-signatures.json). Patterns are script_src, iframe_src, subdomain_link, button_text, or text_marker. SGA-stack vendors (Modento, Neurality, TrueLark, CareStack, NexHealth) are prioritised over third-party when multiple hits occur on the same page.
Verdict. First match wins. "absent" is only set after at least one successful page load returned a 2xx with no signature match. "website_unresolvable" is split between hosts that never resolved (75) and hosts that timed out / errored during the scan window (16).
Evidence. Each row in osa-coverage-gap-resolved.csv records the matched URL fragment / script src and the public site URL. No PHI captured — only public website HTML. Phase A compliant.
Resumability. Progress is checkpointed to progress.json after every 10 practices; the scanner can resume mid-run without re-scanning completed practices.

Bucket counts

Status	Count	Action owner
SGA STACK	67	Engineering — OSA catalog backfill
THIRD-PARTY	8	Small enough to flag, not scrape
ABSENT	73	Marketing — patient-acquisition leak
UNRESOLVABLE	91	Ops — supply URLs
NOT SCANNED	55	Late-resolution rows; sweep in next run
TOTAL	294
