- analyze: cross-references island against vault+carry
- Lexicon methods: org.latha.strata.deriveIsland, org.latha.strata.analyze
- StrataContainer Durable Object manages container lifecycle
- carry-vault pushed to github.com/codegod100/carry-vault (private)

instead of pushing to API endpoints
- Added deriveIsland() with BFS traversal (recursive CTE OOMs in D1)
- New xrpc endpoints:

- GET /xrpc/org.latha.strata.listRecords
- GET /xrpc/org.latha.strata.getIslands
- Frontend supports AT URI as strata page ID
- Lexicon updated: added title field, relaxed source.uri format
- Migrated all /api/ routes to /xrpc/ namespace

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

LLM now produces a [Title] section — a single sentence capturing
the core argument rather than a fragmented topic list. Uploaded
as the island summary via PUT /api/strata/islands/:id/summary.

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
and descriptions. Added card/collection type colors to force graph.

Removed DiscourseGraphRenderer class, types, CSS, and rendering.
The discourse_graph data is still computed and stored in strata
analysis — just not rendered on the page for now.

semble.so/url/<encoded-source-url> instead of profile/<did>.
Also: discourse graph now pan/zoom with fixed viewport.

- Nodes as rounded-rect cards with type badge + short title
- Canvas width scales with max nodes per layer (min 90px spacing)
- Canvas height scales with active layer count
- Hover tooltip shows full title
- Edges connect bottom/top of cards with bezier curves
- Legend moved to bottom-right
- Faded edges (44 alpha) by default, bright on hover

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.

Semble has no dedicated connection record page, so edges now link
to the connection author profile: semble.so/profile/<did>

Layout: summary + graph at top, synthesis below, then themes,
relationships, tensions, open questions, and full node/edge lists
at the bottom.

On rebuild, compute the new lexmin-hash ID for each old island
and carry forward its summary and strata data to the new row.

Shape: 16 hex chars (e.g. "a3f2c8b91e4d7a05"). Stable when
vertices are added, opaque, short enough for URLs and DB keys.

Island ID is now the alphabetically smallest URI in the connected
component, not a hash of all vertices. This keeps the ID stable when
new vertices are added to the island.

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

- Each island card on explore page now has a Strata button that
navigates to the island detail page
- org.latha.strata records now include island graph data (vertices
+ edges) so the record page can render the full constellation
- CarryGraph class renders the island network overlaid with carry
cross-reference nodes: network nodes are circles, carry nodes are
diamonds, carry links are dashed lines
- Legend in the graph canvas shows node types
- CSS for carry graph canvas, island card footer with Strata button

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
