# Scratch

Disposable working memory for one bounded rite.

## Current subgoal: subtraction audit

The fresh-package Ox17 deployment lane is paused. Do not compile, package,
deploy, or resume a historical Ox root until this audit has made the source
machine smaller and the canonical map explicitly reopens that lane.

## Triggering evidence

- Idunn's interrupted native build left three commit-keyed test targets of
  24 GiB, 27 GiB, and 27 GiB plus 19 GiB of release construction caches.
  All were dead compiler scratch and were removed on Yggdrasil; the Cargo
  target root returned to 4 KiB.
- One target consisted of 19 GiB `debug/deps`, 4.9 GiB incremental state, and
  388 MiB build-script output. Several individual test harnesses were
  500--700 MiB.
- `epiphany-core` declared 75 binary targets. The root release bundle declared
  another 26 targets, many by pointing at the same source files. Exact
  `1d5a1f17` reduced core to 30 binaries with zero duplicate owners and removed
  19,252 net non-vendor lines. The current cut reduces core again to its one
  explicit maintenance binary and the package to 25 owned runtime binaries.

The storage failure is evidence of source-shape failure. Build-profile flags
and janitors may reduce the symptom but cannot substitute for deleting code.

## Authority map

- Owner: each live organ or operator tool owns one executable boundary only
  when process isolation, privilege isolation, lifecycle ownership, or an
  independently deployable contract requires it.
- Inputs: the canonical runtime/service maps, Idunn's immutable release bundle,
  current systemd manifests, operator-tool call sites, and source-grounded test
  coverage.
- Outputs: a minimal release binary set and library/integration tests for
  verification that does not need a separately shipped process.
- Derived state: smoke runners, fixtures, benchmarks, and migration probes are
  test/development surfaces. They do not become runtime organs merely because
  Cargo can compile them as binaries.
- Forbidden writers: historical docs, stale smoke commands, and previous
  package manifests cannot preserve an executable that no live authority uses.
- Shared paths: development verification and Idunn acceptance must exercise the
  same library/runtime contracts without compiling duplicate wrappers.
- Cut line: delete unowned legacy executables; collapse table-shaped smoke
  families into ordinary tests; give each surviving production entrypoint one
  Cargo package owner; remove root/core duplicate bin declarations; then
  reassess crate boundaries and the release list. Do not add build cleanup or
  cache machinery as a substitute for this cut.

## Immediate audit order

1. Done in the current worktree: Persona social state is keyed and separately
   owned; the final heartbeat scheduler module, binary, schema, service, store,
   deployment path, pacing/history, stale repair, and acknowledgement consumer
   are deleted. Resident Self owns the complete grant lifecycle directly.
2. Done: delete `runtime_store_migration`, its receipt registration, and its
   test. The approved migration has no writable migrator.
3. Done: delete the local PowerShell operator wrapper, direct Persona/operator
   binaries, shipped `verse-query` control plane, and all Epiphany-owned
   Rider/Unity integration. Brokkr owns Unity through CultMesh/Eve; a future
   Rider daemon owns Rider.
4. Done: reduce `epiphany-core` from 30 binary targets to the one native
   compaction helper. Runtime executables belong to the release bundle.
5. In progress: delete tests that inspect spelling, duplicate constructors, or
   exercise one-line helpers without reaching a consequence. Preserve exact
   CAS, conflict, substitution, concurrency, lifecycle, and re-entry proofs.
   The remaining source-inspection concentration is the daemon supervisor and
   The semantic-memory/workspace-coverage projection stack and its local daemon
   supervisor were deleted at 856648de after proving that no sealed reasoning
   projection consumed them. Repair current maps; preserve history as history.
6. Run focused tests after each cut. Only after source subtraction stabilizes
   should Idunn's build scratch contract be reconsidered.
