Jake 592b894790 docs(cr-2026-04-22): add release-blocker issue tracker at docs/issues/
Captures the 12 items from docs/code-review-2026-04-22.md that
must land before v0.1 ships. One markdown file per issue with:
severity, path:line, problem description, acceptance criteria,
fix scope, and dependency graph.

Split by severity:
- 3 CRITICAL: live-session race, migration atomicity, transcript-
  profile FK
- 9 MAJOR: monolith refactor, channel-fatality, capture worker
  join, runtime capabilities, macOS App Nap, decoder error prop,
  LLM prompt preflight, keystore thread-safety, hotkey device
  filter

README.md indexes them with a fix-order dependency graph and a
fish-shell script for bulk-converting to GitHub issues once `gh`
CLI is installed and authed. Deferred step by user decision —
markdown tracker is authoritative until then.

# RB-03 CRITICAL: transcript provenance can reference deleted profiles
**Severity:** CRITICAL
**Path:** `crates/storage/src/migrations.rs:208-216`, `crates/storage/src/database.rs:61-89`, `:697-708`
**Source:** [2026-04-22 code review](../code-review-2026-04-22.md#c4--transcript-provenance-can-reference-deleted-profiles)
**Labels:** release-blocker, critical, data-integrity, storage
## Problem
v8 migration adds `transcripts.profile_id` but without a `FOREIGN KEY` constraint. `insert_transcript` accepts any `profile_id` string without validation. `delete_profile` doesn't guard against existing transcript references. The combined result: persisted transcripts can keep orphaned profile IDs indefinitely, breaking provenance integrity.
## Acceptance
- A v9 migration adds `FOREIGN KEY (profile_id) REFERENCES profiles(id) ON DELETE RESTRICT` (or `ON DELETE SET NULL` if soft-orphaning is preferred — decide during the fix).
- The migration reconciles existing orphans: either backfill with `DEFAULT_PROFILE_ID`, or null them, per the chosen FK semantic.
- `insert_transcript` passes the FK check — no behaviour change on the happy path.
- `delete_profile` returns a meaningful error when transcripts reference the profile being deleted (or cascades to null, matching the FK semantic).
- Regression tests: (a) delete_profile with transcript references behaves per the chosen semantic; (b) insert_transcript with a non-existent profile_id errors; (c) existing orphans are reconciled on first migration to v9.
## Fix scope
Large. FK constraint design decision + migration + reconciliation + `database.rs` updates + tests.
## Dependencies
- **Blocked by:** RB-02 (migrations atomicity — the v9 migration must be transactional).
