There is no installed base to protect, so the self-contained
`--data-dir P` escape hatch goes away entirely. amy now has exactly
one layout — the production multi-account one — and tests exercise
that same code path. Drops one global flag, one DataDir construction
mode, and the "tests use a different code path than users" footgun.
Layout (unchanged from the previous commits — just the only mode now):
~/.amy/
├── current # `amy use NAME` marker
├── shared/
│ └── events-store/ # FsEventStore, one per machine
├── alice/
│ ├── identity.json
│ ├── state.json
│ ├── aliases.json # {"alice": "<own npub>"} after init
│ └── marmot/
└── bob/ ...
`DataDir.DEFAULT_ROOT` reads `$HOME` directly (falling back to
`user.home`) because JDK 21 resolves `user.home` via getpwuid and
ignores `$HOME` — which would have broken the standard CLI test
isolation pattern of `HOME=/tmp/foo amy …` (the same convention
git, gpg, npm follow).
Test sweep:
- `cli/tests/headless/helpers.sh`, `cli/tests/dm/setup.sh`,
`cli/tests/cache/cache-headless.sh` wrappers all switch to
`HOME=$STATE_DIR amy --name X …`.
- `ensure_identity_for` drops its `dir` parameter; the function and
every harness call site go through `--name` only.
- `A_DIR`/`B_DIR`/`D_DIR` get repointed at `$STATE_DIR/.amy/X`. The
one consumer (`cache-headless.sh`'s T6 `relays.json` check) still
works since it's just a path probe.
- `cli/tests/dm/tests-dm.sh` ghost identities get their own
short-lived `$HOME` so they don't pollute the main test root.
Cache-test T4 inverts: pre-shared-store, "B has not seen A → first
profile show is a relay miss, second is a cache hit" tested
per-account caching. With one shared events-store, B's first lookup
of A is already a cache hit because A wrote kind:0 there during
bootstrap. T4 now asserts that — drops the stale "second lookup hits
cache" half. T7 (no-identity maintenance verbs) gets a fresh fake
`$HOME` plus a throwaway `--name` so the empty store has no inherited
events.
Docs (README + DEVELOPMENT) rewritten to match — quick-start now uses
`amy --name alice create`, the on-disk-layout section shows the new
tree, and the global-flags table replaces `--data-dir` with `--name`
plus the new `amy use` verb.
