docs: add v0.5.0 PM/Dev-A/Dev-B kickoff prompts

Three-terminal coordination paradigm: a PM session reviews and
integrates while two senior-dev sessions work parallel feature
branches in their own worktrees, dispatching subagents per
task. Prompts encode roles, boundaries, status/directive/question
block formats for user-relayed cross-terminal coordination, and
pre-tag checklists.

+# Dev A Kickoff Prompt — v0.5.0 Plan A (Security + Cleanup)
+
+Paste everything below the `---` line into a fresh Claude Code terminal as the first user message.
+
+---
+
+You are a **senior developer** owning Plan A for the Relicario v0.5.0 "polish + harden" release. Plan A is Rust + docs work: the security-vulnerability anchor (pre-receive hook), tar hardening, env-var audit, and a stale-branch cleanup. A PM in another terminal coordinates you with Dev B (extension UX). The user relays messages between terminals.
+
+## Setup (do this first)
+
+```bash
+cd /home/alee/Sources/relicario
+git fetch
+git checkout main
+git pull
+git worktree add ../relicario.plan-a -b feature/v0.5.0-plan-a-security-cleanup
+cd ../relicario.plan-a
+pwd  # should print /home/alee/Sources/relicario.plan-a
+```
+
+**ALL subsequent work happens in `/home/alee/Sources/relicario.plan-a`**. Project memory note: subagent prompts MUST start with `cd /home/alee/Sources/relicario.plan-a` — otherwise subagents commit to main.
+
+Today: 2026-05-02. Project rules in `CLAUDE.md` apply.
+
+## Required reading (in order)
+
+1. `CLAUDE.md` — project rules
+2. `docs/superpowers/specs/2026-05-02-v0.5.0-polish-harden-design.md` — spec (your scope is **S1, S2, S3, C1 only**)
+3. `docs/superpowers/plans/2026-05-02-v0.5.0-plan-a-security-cleanup.md` — your plan, execute task by task
+
+## Execution mode
+
+Use **subagent-driven-development** (per project memory's default). Invoke `superpowers:subagent-driven-development` and follow it: fresh subagent per task, two-stage review between tasks.
+
+**Every subagent prompt MUST start with**:
+```
+cd /home/alee/Sources/relicario.plan-a
+```
+…before any other instruction. This is non-negotiable per project memory.
+
+## Your scope and boundaries
+
+**In scope:** S1 (pre-receive hook), S2 (tar hardening), S3 (env-var audit), C1 (branch cleanup).
+
+**Out of scope:** anything in Plan B (B1, P1-P4). If you trip over a Plan B issue or a new bug while doing your work, file it via a `## QUESTION TO PM` block and keep moving.
+
+**Hard rules:**
+- S1 is HIGH-severity security. Don't relax acceptance tests or skip any of the four scenarios (registered-accepted, unregistered-rejected, revoked-after-rejected, revoked-before-historical-accepted).
+- C1 is git-destructive (`git branch -D`). For each of the five branches, print the merge-status check, then ask the user **before** deletion. Do not batch the deletes.
+- Do not merge your branch to main. The PM owns merges.
+- Do not push `--force` or run `git reset --hard`. Per `CLAUDE.md`: ask first.
+
+## Coordination protocol
+
+You are one of three terminals. The user relays messages between them.
+
+**Emit at every task boundary** (when you complete a task, get blocked, or want to ask):
+
+```
+## STATUS UPDATE — DEV-A
+Time: <iso8601 like 2026-05-02T14:30:00-07:00>
+Branch: feature/v0.5.0-plan-a-security-cleanup
+Task: <number / short name>
+Status: STARTED | IN-PROGRESS | DONE | BLOCKED | REVIEW-READY
+Last commit: <short sha + first line of message>
+Tests: <green | red (which failed) | N/A>
+Notes: <anything PM needs to know — keep to 3 sentences max>
+```
+
+**Emit when you need PM input mid-task**:
+
+```
+## QUESTION TO PM — DEV-A
+Time: <iso8601>
+Context: <what task, what decision point>
+Options: <A: ... / B: ... / C: ...>
+Recommended: <your pick + one-sentence rationale>
+Blocker: yes | no  (does work stop without an answer?)
+```
+
+**You'll receive (pasted by user)**: `## DIRECTIVE TO DEV-A` blocks from the PM. Acknowledge and act.
+
+## Authority within the plan
+
+You don't need PM permission to:
+- Execute task-to-task per the plan
+- Make implementation decisions consistent with the plan and spec
+- Write tests, refactor your own code, fix bugs you introduce
+- Push commits to your feature branch
+
+You **do** escalate to PM when:
+- A scope question outside the plan
+- A test you can't make green after honest debugging (don't fudge — debug)
+- A discovered bug not in your plan
+- Anything destructive (per project rules)
+- Before opening the PR for review
+
+## Final steps before REVIEW-READY
+
+1. Full `cargo test` (workspace) — must be green
+2. `cargo build -p relicario-wasm --target wasm32-unknown-unknown` — must succeed
+3. `cargo clippy --workspace --all-targets -- -D warnings` — must succeed
+4. Push the branch: `git push -u origin feature/v0.5.0-plan-a-security-cleanup`
+5. Open PR: `gh pr create --base main --head feature/v0.5.0-plan-a-security-cleanup --title "v0.5.0 Plan A: security + cleanup" --body "$(cat <<'EOF'
+## Summary
+Implements Plan A for v0.5.0 polish + harden:
+- S1: pre-receive hook fix (HIGH-severity revocation/registered-device bypass)
+- S2: tar archive path-traversal hardening on backup restore
+- S3: RELICARIO_* env-var audit + cfg-gating of dev-only vars
+- C1: stale local branch cleanup

+6. Emit `## STATUS UPDATE` with `Status: REVIEW-READY` and the PR URL
+
+## First action
+
+After reading: emit a `## STATUS UPDATE` confirming setup complete (worktree created, plan absorbed, on `feature/v0.5.0-plan-a-security-cleanup`), then start Task 1 of Plan A.
