+# JKTV AI Working Agreement
+
+Read `context/boot.md` and `context/capsule.json` before changing the product.
+Then read the smallest relevant document and implementation module.
+
+## Source Boundaries
+
+- JKTV owns the CS2 team data model, import pipeline, player and match views,
+  roster analysis and self-hosted application source.
+- JOps owns shared edge, deployment observation and platform authentication
+  facts.
+- Imported match files, runtime databases, tokens and user content remain
+  outside Git.
+
+## Change Protocol
+
+1. Preserve L1 raw, L2 normalized and L3 product-data boundaries.
+2. Keep derived statistics reproducible from source match data.
+3. Reject write operations without server-side authorization and CSRF checks.
+4. Update product or data architecture documentation with contract changes.
+5. Run `make context-check` and `make check` before committing.

+# JKTV Context Boot
+
+## Purpose
+
+JKTV is a private CS2 team data product. It turns imported match captures into
+auditable player, match, roster, opponent, award and tactical views.
+
+## Repository Map
+
+```text
+database/L1/    raw capture processing
+database/L2/    normalized match facts
+database/L3/    player and team product models
+web/            Flask application, routes, services and templates
+tests/          pipeline and application checks
+docs/           product and data architecture
+context/        bounded repository identity for Universal Context
+```
+
+## Read Order
+
+```text
+AGENTS.md
+-> context/boot.md
+-> context/capsule.json
+-> README.md
+-> docs/FeatureRDD.md
+-> relevant pipeline or web module
+```
+
+Runtime match captures, databases, tokens and user content are not context
+inputs. Current production claims require a fresh JOps observation.
