Request changes. The idea — freeze a schema only once it is actually published, instead of on every dev shape change — is the right one, and the machinery around it is careful: the permitted_change allowlist matches the generator's four output locations exactly, the immutability guards (byte comparison of immutable_files plus the before_registry schemas/releases comparison) do catch deletion and rewriting of existing snapshots, path traversal is blocked by the COMPONENT/DIGEST patterns before any git lookup, git merge-base --is-ancestor plus the origin-URL check pins the proof to the fixed data branch, and .copy("Fixtures") covers the new releases/ subdirectory. I also confirmed no dangling references to DashSchemaV3/V4/V5, v2ModelTypes…v4ModelTypes or dash-v2…v5.store remain.
What blocks it is the transition, not the design: as committed, this PR removes more drift protection than it adds, and reuses a shipped version identifier for a different shape. Three inline. Everything after them is a non-blocking recommendation.
I verified the central claims against the branch rather than trusting a summary. Before this PR (ba01d4cd) the fixture set was dash-v1 … dash-v5 with dash-v5 bound to DashSchemaV5, and Schema.Version(5, 0, 0) was the live identifier. At this head the fixture set is dash-v1 alone, bound to frozen DashSchemaV1, the live identifier is Schema.Version(2, 0, 0), and DashReleasedSchemaRegistry.generated.swift contains an empty array.
Non-blocking recommendations:
1. testAcceptedBaselineRemainsInTheMigrationPlan was weakened — DashModelMigrationTests.swift:205. Replacing the exact list comparison with schemas.prefix(1) == ["1.0.0"] plus a uniqueness check means a later change that drops DashSchemaV2 from the plan, reorders it, or swaps in a different enum declaring 2.0.0 passes — and also passes testTheLiveSchemaIsTheMigrationPlansLastVersion. The intended replacement guard lives in DashReleasedSchemaTests, which is inert while the registry is empty, so right now nothing stops a released version from leaving the plan.
2. The V1 doc comment contradicts the PR's premise — DashModelContainer.swift:177. The PR body says "The accepted V1 database remains supported by direct migration into live V2", but the DashSchemaV1 doc comment directly above that line still says V1's identifier "has accumulated several destructive dev-only changes" (unique-attribute retypes String→Data, removed relationship inverses, PersistentAccount.wallet optionality flip) and concludes "any pre-existing dev store will fail to open and get rebuilt from scratch". The committed dash-v1.store was written at 5f58417079, not by the published binary, so nothing in the tree demonstrates that a genuinely published V1 store migrates. Either the accepted-baseline premise the whole automation rests on needs restating, or that doc comment is stale and should be fixed here.
3. DashReleasedSchemaFixture: Sendable holds a non-Sendable member — DashReleasedSchemaTests.swift:7. let version: any VersionedSchema.Type produces "stored property 'version' of 'Sendable'-conforming struct has non-Sendable type" under -swift-version 6. It is only a warning because the test target lacks -warnings-as-errors (the integration target has it) — it becomes a build failure the day that flag goes package-wide.
4. sqlite3 connections are never closed — freeze_schema_models.py:450 and freeze_appstore_release.py:280. with sqlite3.connect(uri, uri=True) as database: commits or rolls back a transaction; it is not a closing wrapper. validate_fixture_description runs once per registry entry from render_all, so every committed fixture stays open for the process lifetime. Harmless on POSIX, but it will block TemporaryDirectory cleanup on a non-POSIX runner and leaks handles as the registry grows — contextlib.closing(...) or an explicit close().

A few clarifications on the remaining review recommendations, checked against this PR's current head:
The empty-registry visibility, stale V1 documentation, and explicit SQLite connection closing recommendations are valid and remain to be addressed. In particular, an empty publication registry should make the two publication-specific tests skip, not fail; the independent runtime checksum test should continue running. This clarification does not dismiss the valid parts of the review. |

Third pass. The XCTSkipIf on the empty registry and the rewritten testMigrationPlanContainsBaselinePublishedAndLiveVersionsInOrder both look right — thanks, those were the two I cared most about.
I also want to withdraw one of my earlier objections. I said reusing 2.0.0 for the collapsed live schema was a blocker because old V2/V3/V4/V5 stores would stop resolving. I went back and dated it: DashSchemaV2 landed in the SDK on 2026-08-26 (00bd049c74), while the most recent dashwallet-ios release tags are v8.6.0 (2026-06-18) and tf-9.0.0__11 (2026-07-23), and there was no public-beta group for 9.1.0 and later. So V2–V5 only ever existed on internal testers' devices, and those get wiped routinely. "Databases from those old development builds are unsupported" is a fair call, and the identifier collision only touches the same population. I'd still spend the free 6.0.0 — schema-releases.json is keyed by this identifier permanently, so an unambiguous record costs nothing here — but it is your call and it does not block the merge.
One thing I do still want to resolve before this lands, inline on the fixture list.
Two questions while you are in here:
-
After the first freeze, what catches a shape change made under the still-current
2.0.0? As far as I can tell the discipline lives only in the doc comment.testPublishedSnapshotsAndRuntimeVersionsMatchCapturedStorescompares a frozen snapshot with a frozen fixture,testPublishedStoresMigrateAndRemainWritableThroughLiveTypeswill happily migrate an additive change and pass, and the plan test compares version lists rather than shapes. Am I missing a guard somewhere? -
Is it deliberate that the app opens the Platform store without the migration plan?
SwiftDashSDKHost.buildModelContainerbuildsModelContainer(for:configurations:)directly, whileDashModelContainer.create— the path the tests use, includingtestV1StoreMigratesToV2AndBackfillsTheKeyLimitColumns— passesmigrationPlan: DashMigrationPlan.self. The V1→V2 delta is additive so implicit migration should cover it, but the next release runs that migration on every App Store device, and it would run it through the untested path. If relying on implicit migration is the intent, it is worth saying so inSCHEMA_RELEASES.md, because then CI is the only thing standing behind the frozen snapshots.

Final validation — Phase 1 + Phase 2
The V1-to-V2 consolidation respects the stated App Store-only compatibility boundary, and published-schema tests compare both snapshots and registered runtime schemas against captured fixtures. Verification found three blockers: a Swift 6 test-compilation error, execution of mutable draft-branch code with release credentials, and missing historical source commits in subsequent verification checkouts. All 43 Python tests and deterministic generation passed with Python 3.9.6; the connection-mock test failed on Python 3.13.14 and 3.14.6, and live inventory validation remains a non-blocking capture-path gap.

- [BLOCKING] packages/swift-sdk/scripts/freeze_appstore_release.py:281-284: Do not execute the draft branch's generator with release credentials
When the deterministic automation branch exists, prepare() checks it out and merges the base into it, preserving branch-only generator changes. This invocation and the later generation/check invocations therefore execute that branch's freeze_schema_models.py. run() passes env=None, so these subprocesses inherit SCHEMA_RELEASE_TOKEN from the workflow. A credential with Platform contents-write access can modify the draft branch's generator, and the next legitimate retry will execute it with the more privileged cross-repository release token—even during a dry run. The later changed-file allowlist runs after execution and does not inspect already-committed branch changes. Execute a trusted generator outside the mutable draft checkout, isolate its imports, and remove release credentials from its subprocess environment; treat the draft checkout as data and output.
- [BLOCKING] packages/swift-sdk/scripts/freeze_appstore_release.py:281-284: Make recorded source commits available in subsequent verification checkouts
The explicitly supported force-updated-history case fetches the released source SHA only into this temporary clone. Recording the SHA in schema-releases.json does not make that commit reachable from the generated snapshot branch. The frozen-schema CI job performs a fresh fetch-depth: 0 checkout and immediately runs --check; render_all() then calls read_inventory() and git show for every registered snapshot's source commit. Full-history fetching does not retrieve unreachable commits merely mentioned in JSON, so the snapshot PR fails verification when its source commit has no fetched ref. Subsequent worker runs also fetch only the current manifest's SHA, leaving earlier snapshots vulnerable to the same failure. Ensure verification checkouts obtain every registered source SHA, or retain those commits through durable Git references.
In `packages/swift-sdk/SwiftTests/SwiftDashSDKTests/DashModelMigrationTests.swift`:
- [BLOCKING] packages/swift-sdk/SwiftTests/SwiftDashSDKTests/DashModelMigrationTests.swift:36: Avoid storing Schema.Version in a nonisolated static constant
The package explicitly uses Swift 6 language mode, but SwiftData.Schema.Version is not Sendable in Xcode 16.4 / Swift 6.1.2. Typechecking this declaration with that toolchain reproduces the error that acceptedBaselineVersions is not concurrency-safe because [Schema.Version] may have shared mutable state. This prevents the test target from compiling before migration tests can execute. The author's discussion of a different VersionedSchema metatype declaration on Swift 6.3.3 does not address this stored array on the older toolchain. Make the array a computed property; the proposed replacement typechecks successfully under the same Swift 6 settings.
In `packages/swift-sdk/scripts/test_freeze_appstore_release.py`:
- [SUGGESTION] packages/swift-sdk/scripts/test_freeze_appstore_release.py:255: Create an explicit cursor mock before configuring fetchone
On Python 3.13.14 and 3.14.6, checked_database.execute.return_value evaluates to sentinel.DEFAULT for this wrapped sqlite3 method. Accessing .fetchone therefore raises AttributeError before the corrupt-fixture path or connection-close assertion runs. Both failures were reproduced locally. The same 43-test suite passes on Python 3.9.6, so this is a Python-version-dependent test defect, not evidence that every run or the current Ubuntu CI interpreter necessarily fails. Explicitly assign a cursor mock for the corrupt case while retaining the wrapped connection so the test still verifies that the real connection closes.
In `packages/swift-sdk/scripts/freeze_schema_models.py`:
- [SUGGESTION] packages/swift-sdk/scripts/freeze_schema_models.py:387-390: Validate live inventory completeness at the capture boundary
The inventory-to-entity membership check runs only when rendering a historical snapshot. --check examines registered historical schemas, while DashSchemaReleaseCaptureTests captures the live store and exports its metadata without consulting schema-models.json. Adding a live model but omitting its inventory entry can therefore pass these checks and produce capture artifacts that the publication worker later refuses to freeze. Updating the inventory afterward cannot repair the inventory at the pinned release SHA. Add a non-mutating capture/preflight check comparing the captured entity membership with the inventory from the same commit, and expose it to the upload workflow. This validates release readiness without freezing development schemas or changing the publication-only registration policy.

Addressed the verified review findings in 10e1062 and companion iOS commit 35d0d3 (#1136).
Two claimed gaps were checked rather than implemented again: published-schema tests already compare runtime and frozen schemas to release evidence, and iOS capture already checks live inventory membership. A fresh published-V2/live-only-property experiment fails exactly on runtime drift; missing/extra inventory regression cases now make the capture check explicit. V1 is unchanged; unpublished beta layouts remain unsupported as agreed. Validation: 48 Python tests, deterministic generation, 13 Release arm64 SDK cases (11 pass, 2 expected skips), clean Replies on each thread give the evidence and disposition. Production initialization/publication/dispatch remains unrun; first-release end-to-end verification is documented. Source-tag protection and GitHub failure notification setup are rollout requirements. Reviewers still need to re-review the new commits; resolving threads does not replace their approval. |

Re-review — Final validation — Phase 1 + Phase 2
The complete PR range at 10e1062 has no remaining blocking findings: four prior findings are fixed, and the inventory-capture finding is withdrawn after independently verifying the companion upload path. One non-blocking issue remains: dry runs skip an existing source-tag integrity check that write runs enforce. Validation passed all 48 Platform Python tests, seven pinned companion capture tests, deterministic generation of 36 files, whitespace checks, and the Swift 6 strict-concurrency probe; the full native SDK suite and production publication flow were not rerun.

- [SUGGESTION] packages/swift-sdk/scripts/freeze_appstore_release.py:385-390: Validate existing source-tag targets during dry runs
This return skips both source-tag creation and the read-only integrity check inside retain_source(). fetch_sources() fetches tags and verifies that each source SHA identifies a commit, but does not verify that swift-schema-source/<SHA> points directly to that named commit. Using the local integration fixture, a dry run succeeded with a conflicting tag while a write run against identical state failed with “Source retention tag points to a different object.” The documented validation preflight therefore misses an already-detectable conflict. Separate existing-tag validation from tag creation and run validation in both modes, including the already-merged-release path. Missing tags should remain permitted during dry runs without creating them.
Merge v4.2-dev while keeping the accepted V1 baseline and live V2. Preserve contract-bound variants and verify their V1 migration without restoring unpublished V3-V5 schemas or fixtures. Pass stored contract values to the token distribution cache so generated historical model copies can use the same helper as live models.

Re-reviewed at 7de890a8. DashLegacySchemaBridge is a real answer to the migration question rather than a patch over it — snapshot, integrity check, migrate a copy, validatePreservation, transactional install, a journal that survives an interrupted run. The care in it is obvious and I am not arguing with the approach.
Four things inline. Three are in the new bridge and are about what happens to stores it was never meant to touch; the fourth is the fixture guard I raised last round, which is still open and which the bridge makes more expensive rather than less.
One more for the record: the companion dashwallet-ios#1136 now calls DashModelContainer.create(url:), an overload that does not exist on v4.2-dev. This PR has to land and the app has to repin before that one can compile, so please keep them in that order.
Two non-blocking notes:
The retained backup is never reclaimed. After a successful bridge only candidate.store is removed (:137); the operation directory keeps original.store — a full copy of the wallet database — under <store>.legacy-v2-backups/<uuid>/ indefinitely. No code path deletes it and SCHEMA_RELEASES.md only says it is retained for recovery. That permanently doubles the on-device footprint for a one-shot migration, on an app that already has a live "no space left on device" failure mode (a truncated sync that never re-matches filters). A retention rule — next successful launch, or an age cutoff — would close it.
PRAGMA journal_mode=DELETE is not checked (DashLegacyStoreSQLite.swift:119). execute() only inspects sqlite3_exec's return code, but a journal_mode pragma SQLite declines to apply still returns SQLITE_OK and reports the current mode as a result row. If a connection still holds the WAL, checkpoint(candidate) reports success while the candidate is still in WAL mode, and the durability loop then fsyncs only the main files. Reading the returned row and asserting it says delete would make that airtight.

Re-review — Final validation — Phase 1 + Phase 2
Two nonblocking release-tooling issues remain: an unrelated closed PR prevents reconciliation of an already-merged release, and snapshot generation accepts omitted persisted value types that remain bound to live definitions. All prior blockers are fixed, and the accepted V1 sources and fixture are unchanged. Local verification passed 66 Python tests, deterministic generation and historical-fixture checks, whitespace checks, and a Swift 6 strict-concurrency probe; both retained findings were independently reproduced, while the full native suite and companion upload workflow were not rerun.

- [SUGGESTION] packages/swift-sdk/scripts/freeze_appstore_release.py:313-316: Reconcile registered releases before rejecting a later closed PR
The automation branch is shared by releases with the same schema version, but this guard runs before checking the requested release's provenance in the merged registry. If release A is merged and a later association PR for release B is closed unmerged, retrying A incorrectly fails with "closed without merging." This reproduces in both dry-run and write modes using the local integration fixture, and prevents A's existing source-tag validation or repair path from running. Check the merged registry and reconcile the requested release before applying this guard. Preserve the newest-attempt rejection for releases that are not already registered; this does not treat an older merge as approval of the rejected follow-up. Add a regression combining an already-registered release with a newer closed-unmerged PR.
In `packages/swift-sdk/scripts/freeze_schema_models.py`:
- [SUGGESTION] packages/swift-sdk/scripts/freeze_schema_models.py:393-403: Validate persisted value-type isolation when generating snapshots
The entity-membership check does not establish that the generated snapshot is independent of live stored value types. An omitted user-defined Codable type is left as a bare reference and can resolve to its live definition. I reproduced this with a model storing an unlisted ProbePayload: render_snapshot accepted the inventory, the generated Swift compiled, and adding a field only to the live payload changed the frozen schema's checksum without changing any generated source. The existing runtime comparisons detect subsequent drift, but can initially accept an incomplete snapshot while its live dependencies still match the captured shape. Add an isolation check for user-defined types in the persisted dependency graph, including transitive Codable fields, and make that validation available before release evidence is admitted. Retain the runtime hash tests. This concerns the new generator's completeness guarantee; no omitted type or migration failure is demonstrated in today's inventory.
Out-of-scope follow-up suggestions (2)
These are valid observations, but they are outside this PR's scope and should be handled in separate issues or author/maintainer-requested PRs rather than blocking this review.
- Move ExampleApp store opening into a recoverable asynchronous startup lifecycle — SwiftExampleAppApp.init() still invokes DashModelContainer.create() synchronously and converts opening errors into fatalError. The default/group-container factory now reaches the potentially expensive legacy bridge, while the SDK's asynchronous overload accepts only an explicit URL. This is a concrete launch-responsiveness and recovery concern, but the ExampleApp lifecycle is unchanged by this PR and its refactor is explicitly excluded from the delivered SDK/publication scope.
- Follow-up: Track a separate consumer-startup change that preserves default/app-group store selection, opens asynchronously, and presents retryable storage failures. Add a matching default/group-container asynchronous factory if that consumer needs it.
- Example app blocks launch on synchronous create and crashes on recoverable bridge errors — OUT_OF_SCOPE: The unchanged ExampleApp initializer does have the cited synchronous call and fatalError, but changing its loading lifecycle is outside the explicitly bounded SDK/publication implementation. Retained as one concrete consumer follow-up rather than an in-scope change request.
- Follow-up: Consider creating a separate issue or author/maintainer-requested PR for this.

Addressed the two new release-tooling findings and the companion wallet-deletion issue in three separate commits:
Validation: 75 Python tests passed; current inventory, deterministic 36-file generation and historical fixture checks passed. Release arm64 simulator SDK suite: 45 cases, 43 passed, 2 expected empty-registry skips. Companion clean dashpay build passed. Frozen V1 and its fixture remain unchanged. For Roman's additional non-blocking notes: the ExampleApp synchronous startup/fatalError concern is valid, but changing its startup/retry UI is a separate consumer lifecycle change; this PR keeps the documented synchronous contract and the production iOS host uses the async factory. It is explicitly deferred, not claimed fixed. Classifying a store as an unsupported beta solely from version 2–5 is unsafe: V2 is also the current legitimate schema, and those numbers can later be published. No reset recommendation based only on a version number is added; the existing owner-controlled development reset guidance remains. The full app Remove/Delete All UI and a production App Store release were not executed. SDK migration-to-deletion behavior was tested on synthetic historical stores. Merge order remains Platform, then iOS. |

Fixed the Swift SDK CI startup failure in 1645f9c. The failed job never reached the SDK build or tests: the runner's temporary scripts are under The Swift workflow now quotes the script path for every Validation: actionlint and the existing self-hosted fork-policy check pass. Isolated executable probes reproduced the old failure and verified the new shell with spaced script/environment paths, both rustup setup paths, Cargo preference preservation, and propagation of command/pipeline/install failures. Full SDK build and tests remain for the new CI run; no SDK or schema code changed in this fix. |

There was a problem hiding this comment.
Re-approving at 209dff28 — my previous approval was dismissed when the new commits landed, so this restores it.
Two of the four things from my follow-up comment are done:
value_typesis now validated, and more thoroughly than I asked.--check-inventorywalks the declaration grammar — nested optional/array/set/dictionary, enum payloads — and rejects transitively missing stored types, not just directly named ones. It is wired through the companion PR'scapture_schema_release.py, which now runs both--check-inventoryand--check. One residual worth knowing: nothing runs it in Platform CI, so a developer who adds a value type and forgets the JSON finds out at release capture rather than on their own PR.- Worker re-runs are idempotent again: the merged-registry early return now precedes the closed-PR guard, with the reasoning in a comment.
The other two are unaddressed and remain your call — the example app still calls create() on the main actor inside App.init() with fatalError, against this PR's own new doc comment, and stores stamped 2.0.0–5.0.0 still surface as a raw Cocoa error rather than the documented "unsupported development database" text.
Nice catch on 209dff28/c2ad0e06, by the way — a full copy of the wallet database surviving a wipe in .legacy-v2-backups/ is the kind of thing that would have been found much later and much more awkwardly.
Four new observations from this pass, none blocking:
The bridge's migration target follows the live graph in practice. DashLegacySchemaBridge.swift:117 builds Schema(versionedSchema: DashSchemaV2.self), and the comment above it says "Never replace this with schema or the latest version" — but DashSchemaV2.models is DashModelContainer.modelTypes, so today they are the same object. Harmless now; the risk is at the V3 step, where V2 must be rebound to its frozen snapshot. If that is missed, a user who skipped the V2 release gets an inferred migration straight into the newest graph, which is precisely what the comment forbids. A real binding to a frozen type would enforce what the comment currently only asks for.
"Recovery is pending" can fire with no journal (:58). The guard checks only that the store file exists; it does not check active.json. If needsMigration came back true at :44 and the file then disappears before StoreLock is taken — an app-group sibling, or the user's own reset — the caller gets "The original database is missing while migration recovery is pending. Recovery files remain at <root>… Do not delete the journal", pointing at a directory that may not exist, and the container never opens again. try ordinary() is the right answer there. Adding FileManager.default.fileExists(atPath: marker.path) to the guard covers it.
Wallet deletion now fails on lock contention (PlatformWalletManager.swift:2574). deleteCompletedSnapshots takes StoreLock, which is flock(LOCK_EX | LOCK_NB), and deleteWallet requires it to succeed before touching keys or rows. Ordering the destructive work after the cleanup is right, but if anything else holds <store>.legacy-v2.lock at that moment — a concurrent create(url:), or the best-effort reclaimAfterSuccessfulOpen on another thread — the user's delete fails with "Another opener is using this database", which does not describe what they were doing. A short bounded retry, or at least a message written for the deletion path, would fit better.
read_registry validates less than the code downstream assumes (freeze_schema_models.py:693). It checks format_version and that schemas is a dict, but render_all then does tuple(map(int, key.split('.'))) on the keys and indexes entry["namespace"] / entry["fixture_sha256"] / entry["fixture_path"] unguarded. A truncated or hand-edited schema-releases.json produces a bare ValueError/KeyError traceback, which inside freeze_appstore_release.prepare surfaces as an anonymous subprocess failure. Everything else in this script fails closed with an explanation; these three spots do not.
For the record, since it came up again in this pass: I am not re-raising the live-schema fixture. testPublishedSnapshotsAndRuntimeVersionsMatchCapturedStores builds a store from the schema registered in the plan under the published identifier — the live graph, for the live version — and compares it against the captured published store, so drift under a published identifier does fail CI. The registry being empty only skips it before the first freeze, and in that window no published store carries that identifier.

Unreleased iOS builds accumulated historical SwiftData versions before App Store publication. Preserve the accepted frozen V1, consolidate unpublished changes into live V2, and retain the exact schema of each subsequent published build. Also provide a bounded upgrade path for older, unversioned databases whose model graph may differ from the accepted V1.
Previous App Store release: provenance and migration rationale
The exact source commits and database schema of the previous App Store binary are not confirmed. Frozen V1 is an accepted compatibility baseline; it is not proof of that binary's model graph. Its definitions, source references and fixture remain unchanged.
The investigated iOS Actions run 32706880873 checked out iOS
8094751eb2be8d52b57da3589fdd2ae2dcd0ecc6and Platformfd8d8d13e5d7cea17b00df5974934ab1910e8039. That run failed during archive, before upload. These commits therefore supply a reproducible historical test case, not verified App Store provenance. The fixture contains synthetic records created on a simulator; it was not extracted from a production device or IPA.Those older sources opened an unversioned
Schema(modelTypes)without a migration plan. The resulting store reports1.0.0, but its entity hashes differ from frozen V1: the accepted V1 adds 13 fields acrossPersistentDocumentTypeandPersistentIndex, with defaults or optional values. The normal staged V1-to-V2 plan rejects this reconstructed store as an unknown source model. An inferred migration can handle the tested additions, so retaining only the explicit plan would unnecessarily strand that upgrade case.The shared container factory now attempts a controlled legacy-to-V2 migration:
1.0.0, with the required core wallet entities and an allowed entity set, qualify for the bridge.DashSchemaV2graph.The release observer's one-time V1 bootstrap records an operational baseline only. It neither freezes/reconstructs the first binary nor migrates a user's database. Unpublished beta schemas remain outside the supported migration history; this bridge does not restore V2–V5 beta guarantees. The synthetic source reconstruction gives regression coverage for a plausible legacy graph, without establishing compatibility with every unidentified production store.
What was done?
DashModelContainer.create(url:)andcreateAsync(url:)so apps with their own store paths use the same behavior; asynchronous opening and migration run on a dedicated queue, with context access kept on the owning actor.swift-schema-source/<full SHA>; verify existing tag targets and release evidence without overwriting them. Dry runs validate existing tags while leaving missing tags untouched.Companion iOS PR: dashpay/dashwallet-ios#1136. Merge Platform first; configure the scoped PAT, initialize the release-observation baseline and verify a dry run before a new promotable build. Initial production end-to-end verification remains required.
How Has This Been Tested?
--check-inventorypasses for current sources.--checkmatches all 36 frozen files. Historical-fixture--checkverifies the 34-entity graph, generated-source digests, recorded source files, SQLite metadata/indexes and fixture checksum. Accepted V1 definitions and fixture bytes are unchanged.dashpayclean simulator build now passes after explicitly rejecting the unsupported.contractGroupkey restriction. Fresh app launch and relaunch with explicit testnet selection reached the Welcome screen; this is not a complete existing-wallet migration smoke test.Breaking Changes
Unpublished V2–V5 layouts are removed from supported historical schemas, and their public intermediate schema types are removed. Development/beta users may need an explicit data reset. Accepted V1 continues through the ordinary migration plan; eligible unrecognized legacy
1.0.0stores use the guarded bridge. There is no automatic database wipe.Checklist:
