fix(storage): declare legacy migration source collections - #150
Conversation
The storage schema now declares the legacy collection names that the migrations read and rewrite, and includes them in the owned collection list so host storage grants cover them. A test asserts every migration source is declared, preventing migrations from failing on undeclared collections. Auto-committed-on: cuttlefish Co-authored-by: Medulla <medulla@tinyhumans.ai>

Verdict: Ready for maintainer review · Priority: medium Diagnostics and supporting detailsFull summaryPull request purpose (title): fix(storage): declare legacy migration source collections. Tiny Sweeper completed its review; deterministic results follow. Review snapshot
Completeness: Complete What changedThe diff adds 14 legacy source collection constants (LEGACY_DELIVERY_*, LEGACY_REMOTE_*, LEGACY_WHATSAPP_*) and a MIGRATION_SOURCE_COLLECTIONS array in crates/tinychannels-bus/src/storage/schema.rs, grows COLLECTIONS from 16 to 30 entries to include them, replaces the string literals in each migration Step.source in src/storage/migrations.rs with the new constants, and adds a regression test in src/storage/migrations_tests.rs asserting every step source is declared by crate::storage::collections(). Migration behavior is unchanged because the constants hold the same string values as the literals they replace. Features

Explanation
The title "fix(storage): declare legacy migration source collections" matches the main change. The PR adds 14 legacy delivery, remote-control, and WhatsApp collection names to the storage COLLECTIONS declarations and a MIGRATION_SOURCE_COLLECTIONS array. Owner migration steps now use the matching LEGACY_* constants. A regression test checks that every migration source is declared. The title is concise, specific, and follows a conventional commit style.

A rabbit checks the names in rows,
Fourteen old collections now show.
The migration steps use constants bright,
Their sources are listed, clear and right.
I thump my paws and nibble greens,
Then hop through tidy storage scenes.

The migration source declaration test now iterates over migration steps instead of the bus crate's source collection list, and lives alongside the other migration tests. This keeps the check in sync with the step definitions it is meant to validate. Auto-committed-on: cuttlefish Co-authored-by: Medulla <medulla@tinyhumans.ai>

Bumps the workspace version for the release that carries #150 (legacy migration sources declared for host storage grants).
The storage migration runner ensures and reads legacy source collections before rewriting them into the current schema. Hosts derive storage grants from the TinyChannels bus contract, so undeclared sources are denied during module startup and can surface as a sanitized ModuleFault.
Add all 14 migration sources to the bus storage declarations, and make the owner migration steps use those constants so schema declarations and migration names cannot drift. Add a regression test that every migration source is declarable through the host-facing collection contract.
