docs: Phase A repo structure — archive, product, kebab-case

- Move copilot history and CSV to docs/archive/
- Add docs/product/ (SSP, intermediate, genre packs) and engineering/adrs/
- Rename all spaced/special-char doc paths to kebab-case
- Nest competitive GTM under docs/gtm/competitive/
- Point README and NORTH_STAR at CANONICAL_STRATEGY
- Leave code/ unchanged for later monorepo Phase B

-## Files
+| Doc | Purpose |
+|-----|---------|
+| [technical-roadmap.md](./technical-roadmap.md) | Phased technical plan (align with strategy when they diverge) |
+| [adrs/](./adrs/) | Architecture decision records |
 
-| File | Description |
-|------|-------------|
-| [Technical Roadmap](./technical%20roadmap.md) | 12-week phased plan: MVP → V1 → Scale |
+**Operating priorities** come from [Canonical Strategy](../strategy/CANONICAL_STRATEGY.md) (§10). When this folder and the strategy disagree, fix one of them deliberately.
 
-## Code
-
-The MCP server implementation lives in the repo root [`code/`](../../code/) directory:
-
-- **`src/index.ts`** — Server entry point (stdio transport)
-- **`src/mcp-server.ts`** — Tool registration (5 MCP tools)
-- **`src/tools/`** — Individual tool implementations
-- **`src/db/`** — PostgreSQL schema + seed data
-- **`src/manifest-generator.ts`** — `/.well-known/mcp-server` JSON manifest
-- **`railway.json`** + **`Dockerfile`** — Deployment config
-
-Every technical decision must trace back to [NORTH_STAR.md](../../NORTH_STAR.md).
+Current implementation lives in `code/` (MCP MVP). A later monorepo phase moves that to `apps/mcp-gateway`.

+# Architecture Decision Records (ADRs)
+
+Short, dated decisions so we do not re-litigate the same choices.
+
+## Format
+
+Each ADR: `NNNN-short-title.md`
+
+```markdown
+# NNNN — Title
+
+**Status:** proposed | accepted | superseded  
+**Date:** YYYY-MM-DD
+
+## Context
+## Decision
+## Consequences
+```
+
+## Index

+| ADR | Title | Status |

+Candidates worth writing soon: HTTP vs stdio for production MCP; Cal.com orchestration vs rebuild booking; monorepo layout (Phase B).
