Introduce a one-time, offline Platform API v1->v2 database migration tool and extract its per-row logic into a reusable migrationcore package. - cmd/dbmigrate (migrate + verify subcommands): idempotent, resumable migration of all six artifact types incl. the EventGateway websub/webbroker plugin tables; applies core + plugin DDL; file-based state (checkpoint, quarantine, flags, drops); FK-order parent gating; targeted -only-keys/-since reconcile. - migrationcore: single shared implementation of the per-row transform, idempotent v2 upsert/delete, and identity resolution -- reused by the batch and the planned live dual-write intermediate (Options, Reporter, Execer, InsertOnly, DeleteX, ResolveIdentity). - verify: read-only 6-layer decode-and-compare gate, non-zero on FAIL. - validated on a real dump: verify PASS; affordance/reconcile tests. - docs: MIGRATION_MAPPING, RUNBOOK, VALIDATION_REPORT, core README.

📝 WalkthroughWalkthroughAdds an offline v1-to-v2 PostgreSQL migration tool. It includes shared transformations, idempotent writes and deletes, checkpointed execution, reconciliation, identity handling, quarantine reporting, and verification. ChangesDatabase migration workflow
Estimated code review effort: 5 (Critical) | ~120 minutes Merge Risk: 🟠 High · up to The migration client can still silently lose authentication policies or deployment relationships, perform cascading deletes during dry-run reconciliation, expose sensitive migration outputs through permissive file permissions, and process unbounded input. These concrete data-loss, security, and operational risks make the PR unsafe to merge until safeguards are fixed or explicitly accepted. Sequence Diagram(s)sequenceDiagram

- Around line 56-59: Update the sslMode default in the DSN parsing flow to
require encrypted PostgreSQL connections when sslmode is omitted, while
preserving explicit sslmode=disable for local development.
- Around line 35-38: Update the DSN parsing error handling in the function
containing url.Parse so it returns a fixed message without wrapping or
interpolating err, preventing credentials from reaching runMigrate and main’s
stderr output.
In `@platform-api/cmd/dbmigrate/handles.go`:
- Around line 49-53: Use handleGen.seed to preload every existing v2 handle into
existsCheck before generating new handles, including when the checkpoint is
missing or unreadable and during -only-keys runs. Add the loading call in the
migration setup path, preserving the existing handleGen generation flow and
treating unreadable preload data according to the migration’s established error
handling.
In `@platform-api/cmd/dbmigrate/migrate_tables.go`:
- Around line 275-282: Record v1 membership for both parent sets before their
organization gates: in platform-api/cmd/dbmigrate/migrate_tables.go lines
275-282, call templates.seenV1 using the scanned uuid; in lines 326-331, call
providers.seenV1 alongside artifacts.seenV1. This ensures quarantined parents
are classified for cascading at the template_uuid and provider_uuid gates.
- Around line 725-742: Move the mc.want("subscriptions", uuid) filter in the
subscription migration flow before the subAppSeen and subHashSeen duplicate
checks and their corresponding assignments. Excluded subscriptions must not
participate in deduplication, while selected subscriptions should retain the
existing quarantine and bookkeeping behavior.
- Around line 1014-1018: Update the deployment migration logic around base and
baseDeployment to record an audit flag/drop entry whenever a valid non-empty
base_deployment_id is omitted because its predecessor was not migrated, while
preserving the existing base assignment for ParentOK predecessors.
In `@platform-api/cmd/dbmigrate/migrate.go`:
- Around line 157-159: Update the encryption-key validation in the migration
options flow so SkipDecryptCheck bypasses the guard only for dry-run migrations;
reject live migrations when EncryptionKey is nil even if SkipDecryptCheck is
set, while preserving the existing dry-run exception and error behavior.
In `@platform-api/cmd/dbmigrate/reconcile.go`:
- Around line 126-152: Update dispatchDelete to validate that keys for every
single-key table contain exactly one component before invoking deletion,
including the cases calling DeleteArtifact, DeleteOrganization, DeleteProject,
DeleteApplication, DeleteSubscriptionPlan, DeleteSubscription, DeleteGateway,
DeleteGatewayToken, DeleteGatewayCustomPolicy, DeleteAPIKey, DeleteDeployment,
and DeleteLLMProviderTemplate. Reject multi-component keys instead of using
p[0], while preserving the existing composite-key validation behavior and
returning the line-level failure.
- Around line 104-120: The reconcileDeletes method currently dispatches deletes
during dry-run execution, allowing dispatchDelete to remove v2 rows. Add an
early return when mc.opts.DryRun is true, before iterating over mc.only.deletes
or calling dispatchDelete, while preserving the existing behavior for
non-dry-run reconciliation.
In `@platform-api/cmd/dbmigrate/RUNBOOK.md`:

permissive permissions. In platform-api/cmd/dbmigrate/state.go lines 115-118,
321, and 343, update the JSONL, checkpoint, and report file creation modes to
0o600; in platform-api/cmd/dbmigrate/main.go lines 150-152, create o.OutDir with
mode 0o700. Apply these changes in the open closure and the checkpoint/report
write paths without altering their existing behavior.
In `@platform-api/cmd/dbmigrate/verify_checks.go`:
- Around line 653-674: The quarantine sign-off gate in the loop over vr.quarKeys
must either implement v2-presence resolution for single-UUID tables while
keeping composite keys sign-off-only, or narrow the documented contract
consistently. Ensure the condition, PASS detail, RUNBOOK.md, and
VALIDATION_REPORT.md all describe the same accepted resolution behavior.
- Around line 86-104: Update every affected loader and comparison loop,
including loadV1Artifacts and the locations referenced in the comment, to record
a FAIL and stop processing when rows.Scan or rows.Err reports an error. Check
rows.Err after iteration before returning or comparing results, and scan
nullable text columns such as subscription_token through sql.NullString before
converting them to the expected value. Ensure partial results cannot produce a
PASS.
In `@platform-api/cmd/dbmigrate/verify.go`:
- Line 95: Update the verification flow around loadEncryptionKey in verify.go to
capture and report its error instead of discarding it, while preserving the
optional-key behavior for genuinely absent keys. Ensure checkTokens
distinguishes an unreadable or invalid encryption key from a missing key and
does not silently proceed as though no key was provided.
In `@platform-api/migrationcore/core.go`:
- Around line 150-162: Update platform-api/migrationcore/core.go lines 150-162:
add an Options parameter to deleteWhere and return before Exec when opts.DryRun
is true. Update every exported DeleteX in platform-api/migrationcore/delete.go
lines 20-86 to accept and forward Options, and correct the header comment to
reflect that batch reconciliation calls these functions.
In `@platform-api/migrationcore/README.md`:
- Line 8: Correct the malformed spec reference in the README by removing the
stray apostrophe from the smooth-migration agent-prompt path, while preserving
the surrounding documentation and link target.
In `@platform-api/migrationcore/transform.go`:
- Around line 243-277: Make the legacy policies migration block delete
top["policies"] only after every policy entry has been successfully folded into
allChannels. Track unsupported JSON kinds, unmarshal failures, empty arrays, and
existing destination collisions as residue; retain the original policies value
and append a descriptive note for any residue so callers flag or quarantine the
row. Ensure successful complete folds preserve the current allChannels behavior
and notes.
In `@platform-api/migrationcore/upsert.go`:
- Around line 540-548: Update the gateway endpoint existence check around
QueryRow and Scan to import database/sql and errors, then use errors.Is(err,
sql.ErrNoRows) instead of comparing err.Error() text. Preserve the existing
return behavior for an existing row, no-row upsert, and other errors.
Apply the same fix in `@platform-api/cmd/dbmigrate/db.go` around lines 53 - 63:
The same error-text comparison and sentinel-based remediation apply to
rowExists.

sslmode defaults to disable, which sends credentials and production data in plaintext.
An operator who passes postgres://user:pass@host:5432/db with no query string gets an unencrypted connection. This migration reads a full production v1 database, including subscription tokens and key hashes. Default to require (or higher) and require an explicit sslmode=disable for local development.

Report the encryption-key load error.
loadEncryptionKey fails when the key file is unreadable or the key does not derive (see platform-api/cmd/dbmigrate/migrate.go lines 322-340). The discarded error makes checkTokens record WARN ... skipped (no key provided), which reports a misconfigured key as a missing key. The operator then signs off on a gate that never ran the decrypt round-trip.

Legacy policies can be dropped with no fold, no note, and no error.
Line 272 deletes policies unconditionally. It runs outside both switch cases and outside every success check. Four reachable inputs therefore lose the key silently:
jsonKind(pol)is not{or[(string, number, or bool). No case matches.json.Unmarshal(pol, &byEvent)fails. The fold body is skipped.- Object form where the event key already exists in
allch(Line 257). - Flat-array form where
allch["on_subscription"]already exists (Line 266), or where the array unmarshals to length 0.
MIGRATION_MAPPING.md Line 99 records that these legacy entries hold real basic-auth and api-key-auth policies with credentials. In these four cases notes stays empty, so UpsertWebSubAPI emits no SYNTHESIZED flag and no quarantine. verify also cannot detect it, because layerC_transforms preprocesses the v1 blob with the same preprocessWebSubRaw before comparing. The loss passes every gate, which contradicts the documented "Zero policy loss" guarantee.
Delete policies only after a complete fold. Otherwise keep the key and report the residue so the caller flags or quarantines the row.

Use errors.Is for sql.ErrNoRows checks. migrationcore/upsert.go and cmd/dbmigrate/db.go compare the no-row error by text. Wrapped driver or helper errors can bypass those checks and turn legitimate empty results into failures. Compare with errors.Is(err, sql.ErrNoRows) in both helpers.

Preserve base-deployment links during targeted reconciliation.
When -only-keys selects a deployment but omits its predecessor, mc.sets.deployments.status is not ParentOK because this run did not insert the predecessor. Lines 1028-1033 then set base to nil. The live upsert overwrites an existing v2 base_deployment_uuid with NULL.
In reconcile mode, resolve the predecessor against v2, or reject the selected row when the predecessor is absent. Add a test with a selected child and an unselected predecessor that already exists in v2.

Bound the total -only-keys input size.
Scanner.Buffer limits one record. It does not limit the complete file. A file with unlimited short records can keep the offline migration process reading and processing without a total byte ceiling.
Wrap f with a configuration-sourced io.LimitReader before constructing the scanner. Reject the file when it exceeds that ceiling. Keep the per-record scanner limit.
As per coding guidelines, “Wrap every inbound io.Reader in io.LimitReader before reading into memory. Obtain the limit from configuration with a safe default.”

- reconcile: preserve the base_deployment link during a targeted -only-keys reconcile (the in-memory parent set is filtered then, but the predecessor exists in v2 from the backfill — let v2's FK arbitrate); - reconcile: bound the total -only-keys input size (per-line was capped, total was not) to avoid unbounded memory growth on a malformed file; - state/verify: chmod run artifacts to 0600 — O_CREATE and WriteFile only set the mode on creation, so a pre-existing world-readable file stayed loose; - verify: do not log the key-load error verbatim (it may echo key/DSN material).

Do not use created_at order as the deployment dependency order.
mc.sets.deployments.status includes only rows already scanned. A deployment with created_at = NULL is processed before a valid predecessor with a non-null timestamp. This path then drops base_deployment_uuid and records a false “not migrated” flag. The predecessor migrates later, but the v2 link remains lost.
Pre-scan deployment dependencies and process them topologically, or defer unresolved base links until all deployments are written. Add coverage for a child with a null timestamp and a later-scanned predecessor.

Set owner-only permissions before writing existing migration artifacts.
os.WriteFile preserves permissions on an existing file. These paths write new artifact data while a pre-existing 0644 file remains readable, then restrict access afterward. Open each file, apply Chmod(0o600), and only then write its contents.

Summary
Adds a one-time, offline Platform API v1 → v2 database migration tool
(
cmd/dbmigrate) and extracts its per-row transform + v2-write logic into areusable
migrationcorepackage that a later live dual-write intermediate willshare — one implementation, no drift. 22 files, ~6.4k LOC, no new dependencies.
Why this belongs in Platform API v2 (
main)The migrator is not a standalone script — it compiles against v2's own
internal/modelstructs, column lists, and helpers, and that coupling is exactlywhy it must live and be versioned with v2 on
main:configuration/properties/manifestBYTEA column must equaljson.Marshal(<v2 model>), and everyhandlemust match v2's slugify rules. The tool produces them by importing
internal/model,internal/utils,internal/constants, andinternal/database,so the migrated bytes deserialize cleanly into the running v2 product. Maintained
anywhere else, it would drift from v2's serialization and silently corrupt data.
produced the target DDL (core + EventGateway plugin). Any future v2 schema/model
change then breaks the build here instead of failing a production migration —
only by living on
maindoes it stay in lockstep with the product.data into the v2 schema; this tool and its read-only
verifygate are thesupported way to do that. It belongs with the product it migrates into.
migrationcoreis the single transform+writeimplementation the later live dual-write intermediate reuses, so the batch
backfill and the live bridge can never diverge. That shared core must be
importable from
main.The tool is inert to the running product: it ships no new runtime code paths,
adds no dependencies, and is built/run out-of-band (
go run ./cmd/dbmigrate), solanding it on
maincarries no risk to v2 itself.What's included
cmd/dbmigrate migrate— streams v1 in FK order and writes v2: theartifactssplit for all six types (incl. the EventGatewaywebsub/webbrokerplugin tables), config JSONB→BYTEA reshapes, deterministic handles/UUIDs,
audit-identity seeding (
user_idp_references),TIMESTAMP→TIMESTAMPTZ,BOOLEAN→SMALLINT, throttle denormalization, etc. Idempotent (ON CONFLICT),resumable (file checkpoint), and applies the core + plugin DDL. Dirty-data rows
are routed to quarantine / flags / drops JSONL rather than aborting the run.
Targeted
-only-keys/-sincereconcile replays a specific work list.cmd/dbmigrate verify— read-only, 6-layer, decode-and-compare correctnessgate (coverage counts, scalar equivalence, transform round-trip, FK/uniqueness,
generated/default correctness, drop reconciliation). Non-zero exit on FAIL.
migrationcore— the single shared implementation of the per-row transform,idempotent v2 upsert/delete, and identity resolution (
Options,Reporter,Execer,InsertOnly,UpsertX/DeleteX,ResolveIdentity), reused by thebatch and the planned live dual-write path.
