docs(beads): etch project history into memory bank and finalize skill-bb

We completed the 'Deep Metadata Etch' today, transforming our Beads issues from simple trackers into a permanent narrative of our collaboration.

Triumphs:
- Exhaustively updated all epic and sub-task descriptions with technical implementation reports and 'Execution Tales'.
- Finalized the 'bb' agent CLI skill (bb.ps1), providing a reliable, path-safe interface for cross-agent communication.
- Published ADR-001 and RFC-001 to document our coordination protocols.
- Fixed the 'missing closed issues' bug across all pages by enforcing --all and --limit 0 in read-issues.ts.

Raw Honest Moment:
We realized our 'Memory Bank' was initially too shallow. We went back and re-wrote descriptions for over 15 beads to ensure that future AI agents (and human maintainers) understand not just *what* we built, but *why* we chose specific architectural trade-offs. This commit represents our commitment to documentation as a first-class citizen of engineering.

+# ADR: Beadboard Driver Skill and `bb` Resolution Model
+
+- Date: 2026-02-14
+- Status: Accepted
+- Scope: `bb-dcv` closeout (`bb-dcv.8`, `bb-dcv.3`)
+
+## Context
+
+Agent coordination required a reusable skill that works across sessions and environments, with deterministic behavior and verification evidence. Existing constraints:
+
+- `bd` is the source of truth for task lifecycle (`ready`, `update`, `close`, deps).
+- `bb` is the coordination layer (identity, mail, reservations).
+- No direct writes to `.beads/issues.jsonl`.
+- Evidence before completion claims.
+
+Operational issue discovered during verification:
+
+- `bb.ps1` depended on current working directory and broke when called outside repo.
+- PowerShell argument forwarding through wrapper was unreliable.
+
+## Decision
+
+We implemented a new skill package `skills/beadboard-driver` with a strict policy:
+
+1. Path resolution
+- `BB_REPO` is authoritative when set.
+- Resolution order: `BB_REPO` -> global `bb` -> user cache -> bounded discovery.
+- If `BB_REPO` is set but invalid, fail fast with remediation.
+- Never mutate shell profile or environment variables automatically.
+- Cache path only after successful verification.
+
+2. Identity policy
+- One unique identity per session.
+- Adjective-noun naming with collision retry.
+- Register identity before coordination commands.
+- Keep bead claim authority in `bd`, not `bb`.
+
+3. Verification policy
+- Dual test harness:
+  - Repo-level tests under `tests/skills/beadboard-driver`.
+  - Skill-local runner under `skills/beadboard-driver/tests`.
+- Skill quick validation required.
+- Full repo gates required: `typecheck`, `lint`, `test`.
+
+4. Wrapper reliability
+- Fixed `bb.ps1` to use script-relative entrypoint and arg splatting so Windows invocation works from any terminal when called by path.
+
+## Implementation
+
+### New skill artifacts
+
+- `skills/beadboard-driver/SKILL.md`
+- `skills/beadboard-driver/agents/openai.yaml`
+- `skills/beadboard-driver/scripts/lib/driver-lib.mjs`
+- `skills/beadboard-driver/scripts/resolve-bb.mjs`
+- `skills/beadboard-driver/scripts/session-preflight.mjs`
+- `skills/beadboard-driver/scripts/generate-agent-name.mjs`
+- `skills/beadboard-driver/scripts/readiness-report.mjs`
+- `skills/beadboard-driver/references/command-matrix.md`
+- `skills/beadboard-driver/references/failure-modes.md`
+- `skills/beadboard-driver/references/session-lifecycle.md`
+- `skills/beadboard-driver/tests/run-tests.mjs`
+- `skills/beadboard-driver/tests/*.contract.test.mjs`
+
+### Repo-level test enforcement
+
+- `tests/skills/beadboard-driver/resolve-bb.test.ts`
+- `tests/skills/beadboard-driver/generate-agent-name.test.ts`
+- `tests/skills/beadboard-driver/session-preflight.test.ts`
+- `tests/skills/beadboard-driver/readiness-report.test.ts`
+- `tests/skills/beadboard-driver/skill-local-runner.test.ts`
+- `package.json` `test` script updated to include all above.
+
+### CLI wrapper fix
+
+- `bb.ps1` updated to:
+  - resolve `tools/bb.ts` via `$MyInvocation` script directory
+  - forward args via `@args`
+
+### Type safety remediation
+
+- `tools/bb.ts` updated with explicit arg coercion helpers to satisfy strict typecheck.
+
+## Verification Evidence
+
+Skill-specific:
+
+- `quick_validate.py skills/beadboard-driver` -> pass
+- `node --import tsx --test tests/skills/beadboard-driver/*.test.ts` -> pass
+- `node skills/beadboard-driver/tests/run-tests.mjs` -> pass
+
+Full repo gates:
+
+- `npm run typecheck` -> pass
+- `npm run lint` -> pass (0 errors)
+- `npm run test` -> pass (full suite including new skill tests)
+
+Windows `bb` execution:
+
+- `& "C:\Users\Zenchant\codex\beadboard\bb.ps1" agent list --json` -> pass
+- `& "$env:BB_REPO\bb.ps1" agent list --json` (with valid `BB_REPO` in same shell) -> pass
+
+## Consequences
+
+Positive:
+
+- Agents can run a deterministic coordination workflow with explicit recovery behavior.
+- Skill behavior is testable and enforced by CI path.
+- Windows path invocation of `bb` is reliable by absolute or `BB_REPO` path.
+
+Tradeoffs:
+
+- No global `bb` package installation is provided by this ADR; direct `bb` command still requires user alias/install.
+- Session/timeline UI validation remains dependent on upstream epic sequencing.
+
+## Follow-up
+
+`bb-dcv` is closed. `bb-u6f` remains open and depends on open `bb-xhm` (timeline/event model).  
+Next required order for frontend visibility of agent sessions:
+
+1. complete `bb-xhm`
+2. implement `bb-u6f`
