Slice 2c of the route-domain reorganization (#4082/#4071, per
specs/architecture-runtime-inventory.md §6.3). Moves memory_routes.py into
routes/memory/, leaving a backward-compat sys.modules shim at the old path.
Pure file reorganization, no behavior change.
The shim uses sys.modules replacement (same pattern as the merged gallery
#4903 and research #4975 slices) so that `import routes.memory_routes`,
`from routes.memory_routes import X`, `importlib.import_module(...)`, and
the `import ... as mr` + `monkeypatch.setattr(mr, ...)` pattern used by
test_memory_routes_session_owner.py / test_memory_owner_isolation.py all
operate on the same module object the application uses.
The canonical module does NOT depend on the shim — routes/memory/
memory_routes.py imports only from services/, core/, src/, and stdlib (zero
internal routes/ coupling).
Four source-introspection test sites repointed to the new canonical path:
- test_direct_upload_limits.py
- test_upload_limits_centralized.py (two dict keys)
- test_vision_owner_scope.py
Adds tests/test_memory_routes_shim.py to pin the sys.modules shim contract
(legacy and canonical paths resolve to the same module object; monkeypatch
via legacy alias reaches the canonical module).
Verified: compileall clean; full suite 4219 passed, 3 skipped.
Move every per-route upload byte-limit into src/upload_limits.py as a
validated, env-overridable constant via read_byte_limit_env:
- Add GALLERY_UPLOAD_MAX_BYTES, GALLERY_TRANSFORM_UPLOAD_MAX_BYTES,
MEMORY_IMPORT_MAX_BYTES, PERSONAL_UPLOAD_MAX_BYTES,
EMAIL_COMPOSE_UPLOAD_MAX_BYTES, STT_MAX_AUDIO_BYTES, ICS_MAX_BYTES.
- Routes import their constant instead of defining it locally: replaces 4
raw int(os.getenv(...)) and removes 3 hardcoded literals.
- The 3 previously-hardcoded limits (email compose, STT audio, calendar
ICS) are now env-overridable with the same ODYSSEUS_*_MAX_BYTES naming.
- Defaults unchanged, so behavior is unchanged unless an env var is set;
an invalid value now fails fast with a clear message instead of a bare
int() ValueError.
- Document all env vars in .env.example and the README.
