+# Q1 — the fifteen silent rooms
+
+Recovered from public sources only, 2026-09-24, by zephyrus-sparkborn.
+Method: five parallel researchers, three spaces each; exact quoted space-id and tweet-id web searches,
+Wayback/archive.today queries, X announcement posts, Stackchain Signal podcast feed (full RSS, 56 episodes,
+Nov 2022–Dec 2023), YouTube, community mirrors, GitHub/gist transcript searches, third-party X mirrors.
+Announcement dates derived from the X status IDs themselves (snowflake timestamps, UTC).
+
+**Verdict: 0 of 15 recovered — nothing found for every room.** Each is a genuine multi-source negative,
+not a search error. Per the archive's own rule, absence here is not evidence of absence.

+## Searches performed (behind the negatives)
+
+All 15 spaces, all 2026-09-24:
+- Exact quoted space-id web searches (`"1mnxedROgmLJX"` etc.) — zero or junk-only results (unrelated PDFs, datasheets, product catalogs). No indexed mention of any id, title, speaker, audio, or recap.
+- Exact quoted announcement-post-ID searches (`"1549953716219809792"` etc.) — junk only.
+- Quoted announcement URLs (`"twitter.com/AnthonyDessauer/status/…"`, `"x.com/AnthonyDessauer/status/…"`) — no mirrors indexed.
+- Wayback queries (space id / tweet id / announcement URL) — no snapshots found. Direct CDX API fetch fails from this environment; used search-engine and archive.today queries instead.
+- archive.today / archive.ph queries with tweet IDs — no copies found.
+- X announcement posts themselves — fetch attempts failed; X status pages are login-walled. Post content (titles, hosts, attendees) is not visible and was not guessed. Existence of the posts is taken from the queue as given.
+- YouTube / recap / write-up searches (date variants, nostr/substack/medium variants) — no mirrors or contemporary write-ups.
+- GitHub/gist transcript searches — nothing.
+- Third-party X mirrors (xstalk, twstalker) — no indexed AnthonyDessauer profile pages.
+
+## Context findings (not per-space recoveries)
+
+- The Stackchain Signal podcast (the community's spaces-recording project) re-publishes older rooms as "From the Archives Series", but its archived originals begin with airdate **8-25-22** ("Battle of 1665", "Battle of 1492"). Full RSS scan (56 episodes, https://anchor.fm/s/c64de45c/podcast/rss, retrieved 2026-09-24) confirms: **no archived original predates 8-25-22**, so all twelve July/early-August rooms fall in the gap before systematic recording. The Aug 16/21/26 rooms are likewise absent (nearest: 8-25-22). This plausibly explains the silence.
+- The archive itself (https://alexanderwhitestone.com/stackchain/, viewed 2026-09-24) confirms the cohort: "31 base transcripts; 15 additional discovered Spaces lacked accessible metadata or replay."
+- alphagrowth.io hosts an archived-Twitter-Spaces MP3 directory, but no AnthonyDessauer/Stackchain Aug-2022 entries surfaced via search.
+
+## Recommended follow-ups
+
+1. **Logged-in X session**: open the 15 announcement URLs — the space card on each post shows the room title, which alone would recover 15 titles.
+2. **Recheck the Stackchain Signal feed periodically**: if the "From the Archives Series" ever back-fills pre-Aug-25-2022 rooms, re-run these ids against it.
+3. Wayback CDX from an environment where it works: bulk-check all 15 announcement URLs and `twitter.com/i/spaces/<id>` for captures.
