Two strata records can share the same graph (same connected component)
but have different analyses. The lexmin hash conflated them. Now the ID
is the record rkey (e.g. 3mlrokf4gho2i), so each strata record is
distinct. Also simplifies getIsland — direct URI lookup instead of
scanning all records.

resolveVertexMeta was doing 14 sequential D1 queries (cards+citations,
chunked at 50). Now builds all statements upfront and runs them in a
single db.batch() call. Also removed ensureContrailReady from getIslands
entirely — it only needs D1.

940ms → 320ms cold, 200ms warm.

- Canvas height 200px → 320px (was cramming 301 nodes vertically)
- Remove hardcoded width/height HTML attrs — constructor sizes via
getBoundingClientRect + devicePixelRatio
- Repulsion force 300 → 500 for better spread
- Warmup ticks 120 → 200 for settled layout

Explore page fetches ?summary=true — skips vertexMeta (244KB saved)
and trims edges to source/target/connectionType. Full data loads
on demand when viewing an island detail. Also skips contrail init
in summary mode for faster cold starts.

523KB → 216KB, 1.2s → 230ms cold, 90ms warm.

Lexicon: connections field now holds objects {uri, source, target,

LLM was paraphrasing/abbreviating titles which broke linking.
Added explicit instruction to use EXACT titles from island data.

- Links now point to semble.so/url/<encoded-uri> instead of raw URLs
- Excludes at:// titles from link map
- Added substring matching: short names from titles (before delimiters/
parens) are linked if they appear in relationship text
- Fixes most "leads to" etc being unlinked

Cards and collections stored as at:// URIs were showing as raw
URIs with type "unknown". Now resolveVertexMeta also queries
records_card and records_collection by AT URI to get titles

Layered graph modeled on Discourse Graphs (discoursegraphs.com):
4 node types — QUE (question), CLM (claim), EVD (evidence),
SRC (source) — arranged in horizontal layers top to bottom.
Edges typed as supports/opposes/informs/addresses with color
coding and curved bezier paths.

Computation: LLM classifies vertices and identifies discourse
relations during strata analysis. Data uploaded via API as
discourse_graph field in strata JSON.

Strata analysis now runs on cloudy (local machine) via
scripts/strata-analyze.py, not in a Cloudflare Container. The script
fetches islands from the API, asks letta to produce structured prose
with semantic arrows (→, ←, ↔, ⇏), then uploads the results to
Cloudflare via PUT /api/strata/islands/:id/analysis.

The strata page renders prose with styled arrows showing relationships
between vertices — no canvas graph. Island cards link directly to the
strata page and show "View Strata" when analysis exists.

- Removed: AnalysisContainer durable object, container analysis endpoint,
CarryGraph class, apiPost helper, POST /api/strata/analyze
- Added: PUT /api/strata/islands/:id/analysis endpoint, strata column
in island_cache, scripts/strata-analyze.py, D1 migration
- Frontend: strata page shows prose with arrows, themes, tensions,
open questions, synthesis

navigates to the island detail page
- org.latha.strata records now include island graph data (vertices

diamonds, carry links are dashed lines

Replace preemptive card analysis with island detection (connected
components from network.cosmik.connection records). Each island is
a cluster of linked URLs — the explore page shows islands as cards.

- Worker: detectIslands() BFS for connected components, /api/strata/islands
endpoint, Strata analyze creates org.latha.strata record in D1 and
returns at-uri, removed analyzeNewCards cron
- Container: analysis accepts island (vertices + edges) instead of
single source, cross-references entire cluster against vault + carry
- Frontend: island cards on explore page, Strata button runs analysis
and navigates to /strata?uri= record page, removed modal approach
- CSS: island-card, island-detail, strata-record styles
