banger hasn't shipped a public release — every "legacy", "pre-opt-in",
"previously", "migration note", "no longer" reference in the tree is
pinning against a state no real user's install has ever been in.
That scaffolding has weight: it's a coordinate system future readers
have to decode, and it keeps dead code alive.
Removed (code):
- internal/daemon/ssh_client_config.go
- vmSSHConfigIncludeBegin / vmSSHConfigIncludeEnd constants and
every `removeManagedBlock(existing, vm...)` call they enabled
(legacy inline `Host *.vm` block scrub)
- cleanupLegacySSHConfigDir (+ its caller in syncVMSSHClientConfig)
— wiped a pre-opt-in sibling file under $ConfigDir/ssh
- sameDirOrParent + resolvePathForComparison — only ever used
by cleanupLegacySSHConfigDir
- the "also check legacy marker" fallback in
UserSSHIncludeInstalled / UninstallUserSSHInclude
- internal/store/migrations.go
- migrateDropDeadImageColumns (migration 2) + its slice entry
- dropColumnIfExists (orphaned after the above)
- addColumnIfMissing + the whole "columns added across the pre-
versioning lifetime" block at the end of migrateBaseline —
subsumed into the baseline CREATE TABLE
- `packages_path TEXT` column on the images table (the
throwaway migration 2 dropped it, but there was never any
reader)
- internal/daemon/vm.go
- vmDNSRecordName local wrapper — was justified as "avoid
pulling vmdns into every file"; three of four callers already
imported vmdns directly, so inline the one stray call
- internal/cli/cli_test.go
- TestLegacyRemovedCommandIsRejected (`tui` subcommand never
shipped)
Removed / simplified (tests):
- ssh_client_config_test.go: dropped TestSameDirOrParentHandlesSymlinks,
TestSyncVMSSHClientConfigPreservesUserKeyInLegacyDir,
TestSyncVMSSHClientConfigNarrowsCleanupToLegacyFile,
TestSyncVMSSHClientConfigLeavesUnexpectedLegacyContents,
TestInstallUserSSHIncludeMigratesLegacyInlineBlock, plus the
"legacy posture" regression strings in the remaining happy-path
test; TestUninstallUserSSHIncludeRemovesBothMarkerBlocks collapsed
to a single-block test
- migrations_test.go: dropped TestMigrateDropDeadImageColumns_AcrossInstallPaths,
TestDropColumnIfExistsIsIdempotent; TestOpenReadOnlyDoesNotRunMigrations
simplified to test against the baseline marker
Removed (docs):
- README.md "**Migration note.**" blockquote about the SSH-key path move
- docs/advanced.md parenthetical "(the old behaviour)"
Reworded (comments):
- Dropped "Previously this file also contained LogLevel DEBUG3..."
history from vm_disk.go's sshdGuestConfig doc
- Dropped "Call sites that previously read vm.Runtime.{PID,...}"
from vm_handles.go; now documents the current contract
- Dropped "Pre-v0.1 the defaults are" scaffolding in doctor_test.go
- Dropped "no longer does its own git inspection" phrasing in vm_run.go
- Dropped the "(also cleans up legacy inline block from pre-opt-in
builds)" aside on the `ssh-config` CLI docstring
- Renamed test var `legacyKey` → `existingKey` in vm_test.go; its
purpose was "pre-existing authorized_keys line," not banger-legacy

Three drift items surfaced in review, each dead on arrival and each
worth trusting a little more at v0.1.0.
config: drop MetricsPollInterval. The field was parsed from TOML
(metrics_poll_interval), stored on DaemonConfig, and ignored by every
consumer — only StatsPollInterval drives the background poll loop.
Users setting it in config.toml saw zero effect. Removed from the TOML
surface, the model constant, and the config test.
daemon: delete ensureDefaultImage. No callers, body was `_ = ctx;
return nil`. Dead since whatever flow used to call it got removed.
store: drop packages_path from the images table. The column was
carried by the baseline migration but never referenced by UpsertImage
(no INSERT / UPDATE mention) or any Go model field — a ghost from a
build pipeline that no longer exists. Added migration id=2
(drop_dead_image_columns) with an idempotent dropColumnIfExists
helper: fresh installs run baseline (creates the column) + 2 (drops
it); legacy DBs where the column was never added get a no-op. Updated
the direct-INSERT SQL in TestGetImageRejectsMalformedTimestamp to
drop the column reference, and added a migration test covering both
install paths (fresh + legacy).

The old migrate() helper only knew how to re-run a fixed slab of CREATE
TABLE IF NOT EXISTS plus per-column ensureColumnExists calls. That worked
while every schema change was a benign additive column; it falls apart
as soon as we need a data backfill, an index, a rename, or anything that
has to happen exactly once in a known order.
Replaces it with a schema_migrations table + ordered []migration slice.
Each migration has a unique id, a human-readable name, and a func(*Tx)
body; the runner opens a transaction per migration so DDL and any data
changes either both land and get recorded or both roll back together,
leaving the DB in a state where retrying on next Open() reapplies from
the same point.
Migration 1 ("baseline") collapses the current schema into one entry:
fresh databases apply it in one shot; existing dev databases see
idempotent `CREATE TABLE IF NOT EXISTS` + `ALTER TABLE … ADD COLUMN`
statements that succeed as no-ops, and the only net effect is the
schema_migrations row that brings them into the versioned system.
Tests cover fresh apply, idempotent re-open, skipping already-applied
ids, rollback on body error (the transient table the migration created
must not survive), and duplicate-id rejection.
