From 392d4fc97ee21bc650c0e967d555303aec6db557 Mon Sep 17 00:00:00 2001 From: James Ross Date: Fri, 3 Apr 2026 17:29:08 -0700 Subject: [PATCH 01/49] =?UTF-8?q?feat:=20WorldlineSelector=20class=20hiera?= =?UTF-8?q?rchy=20=E2=80=94=20RED=E2=86=92GREEN?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Four new domain types replacing the WorldlineSource discriminated union: - WorldlineSelector (abstract base, from() factory, toDTO() bridge) - LiveSelector (canonical worldline, validated ceiling) - CoordinateSelector (hypothetical worldline, private #frontier with defensive copy, validated ceiling, accepts empty frontier) - StrandSelector (isolated worldline, validated strandId + ceiling) Real extends inheritance — instanceof WorldlineSelector works. Constructor validation — rejects invalid ceiling, empty strandId, non-object frontier. Object.freeze on all instances. Map immutability via private field + defensive copy getter. 51 tests covering: instanceof, constructor validation, freeze, clone independence, toDTO, from() boundary factory, mutation isolation. --- src/domain/types/CoordinateSelector.js | 72 ++++ src/domain/types/LiveSelector.js | 49 +++ src/domain/types/StrandSelector.js | 57 +++ src/domain/types/WorldlineSelector.js | 119 +++++++ .../domain/types/WorldlineSelector.test.js | 325 ++++++++++++++++++ 5 files changed, 622 insertions(+) create mode 100644 src/domain/types/CoordinateSelector.js create mode 100644 src/domain/types/LiveSelector.js create mode 100644 src/domain/types/StrandSelector.js create mode 100644 src/domain/types/WorldlineSelector.js create mode 100644 test/unit/domain/types/WorldlineSelector.test.js diff --git a/src/domain/types/CoordinateSelector.js b/src/domain/types/CoordinateSelector.js new file mode 100644 index 00000000..1aa99f93 --- /dev/null +++ b/src/domain/types/CoordinateSelector.js @@ -0,0 +1,72 @@ +/** + * CoordinateSelector — observe a hypothetical worldline at specific writer tips. + * + * @module domain/types/CoordinateSelector + */ + +import WorldlineSelector, { validateCeiling } from './WorldlineSelector.js'; + +/** + * Worldline selector pinned to an explicit writer-tip coordinate. + * + * The coordinate specifies a hypothetical worldline that would result + * from merging only these writers at these commit SHAs.

PatchJournalPort is wired through the full call chain: WarpRuntime → PatchController → Writer → PatchBuilderV2, and WarpRuntime → SyncController → SyncProtocol. Changes: - Writer: replace codec/patchBlobStorage with patchJournal - PatchController: pass patchJournal instead of codec to Writer and PatchBuilderV2; use patchJournal.readPatch() for patch loading - SyncController: pass patchJournal instead of codec to SyncProtocol - StrandService: wire patchJournal to PatchBuilderV2 constructions - WarpRuntime: accept patchJournal param, store as _patchJournal Hex tripwire is GREEN: all 27 checks pass across PatchBuilderV2, SyncProtocol, and Writer.

Legacy codec-based paths remain as fallback. `WarpRuntime.open()` auto-constructs a `CborCheckpointStoreAdapter` when no explicit store is provided, matching the `patchJournal` auto-construction pattern. - **The Method** — introduced `METHOD.md` as the development process framework. Filesystem-native backlog (`docs/method/backlog/`) with lane directories (`inbox/`, `asap/`, `up-next/`, `cool-ideas/`, `bad-code/`). Legend-prefixed filenames (`PROTO_`, `TRUST_`, `VIZ_`, `TUI_`, `DX_`, `PERF_`). Sequential cycle numbering (`docs/design//`). Dual-audience design docs (sponsor human + sponsor agent). Replaced B-number system entirely. - **Backlog migration** — all 49 B-number and OG items migrated from `BACKLOG/` to `docs/method/backlog/` lanes. Tech debt journal (`.claude/bad_code.md`) split into 10 individual files in `bad-code/`. Cool ideas journal split into 13 individual files in `cool-ideas/`. `docs/release.md` moved to `docs/method/release.md`. `BACKLOG/` directory removed. diff --git a/src/domain/WarpRuntime.js b/src/domain/WarpRuntime.js index cf85e42a..c4768bcc 100644 --- a/src/domain/WarpRuntime.js +++ b/src/domain/WarpRuntime.js @@ -360,6 +360,9 @@ export default class WarpRuntime { /** @type {import('./services/EffectPipeline.js').EffectPipeline|null} */ this._effectPipeline = null; + + /** @type {import('../ports/CheckpointStorePort.js').default|null} */ + this._checkpointStore = null; } /** @@ -491,7 +494,7 @@ export default class WarpRuntime { */ // TODO(OG): split open() validation/bootstrapping; legacy hotspot kept explicit until the API redesign cycle. // eslint-disable-next-line max-lines-per-function, complexity - static async open({ persistence, graphName, writerId, gcPolicy = {}, adjacencyCacheSize, checkpointPolicy, autoMaterialize, onDeleteWithData, logger, clock, crypto, codec, seekCache, audit, blobStorage, patchBlobStorage, patchJournal, trust, effectPipeline, effectSinks, externalizationPolicy }) { + static async open({ persistence, graphName, writerId, gcPolicy = {}, adjacencyCacheSize, checkpointPolicy, autoMaterialize, onDeleteWithData, logger, clock, crypto, codec, seekCache, audit, blobStorage, patchBlobStorage, patchJournal, checkpointStore, trust, effectPipeline, effectSinks, externalizationPolicy }) { // Validate inputs validateGraphName(graphName); validateWriterId(writerId); @@ -552,6 +555,21 @@ export default class WarpRuntime { }); } + // Auto-construct checkpointStore when none provided: same pattern as patchJournal. + if (checkpointStore !== undefined && checkpointStore !== null) { + // eslint-disable-next-line @typescript-eslint/no-unsafe-assignment -- WarpRuntime options are untyped; cast narrows + graph._checkpointStore = /** @type {import('../ports/CheckpointStorePort.js').default} */ (checkpointStore); + } else { + const { CborCheckpointStoreAdapter } = await import( + /* webpackIgnore: true */ '../infrastructure/adapters/CborCheckpointStoreAdapter.js' + ); + graph._checkpointStore = new CborCheckpointStoreAdapter({ + codec: graph._codec, + blobPort: /** @type {import('../ports/BlobPort.js').default} */ (persistence), + crypto: graph._crypto, + }); + } + // Validate migration boundary await graph._validateMigrationBoundary(); diff --git a/src/domain/services/controllers/CheckpointController.js b/src/domain/services/controllers/CheckpointController.js index 1dc4e21d..81847b28 100644 --- a/src/domain/services/controllers/CheckpointController.js +++ b/src/domain/services/controllers/CheckpointController.js @@ -86,6 +86,8 @@ export default class CheckpointController { /** @type {CorePersistence} */ const persistence = h._persistence; + /** @type {import('../../../ports/CheckpointStorePort.js').default|null} */ + const checkpointStore = /** @type {import('../../../ports/CheckpointStorePort.js').default|null} */ (h._checkpointStore); const checkpointSha = await createCheckpointCommit({ persistence, graphName: h._graphName, @@ -96,6 +98,7 @@ export default class CheckpointController { crypto: h._crypto, codec: h._codec, ...(indexTree ?

charset=UTF-8 Content-Transfer-Encoding: 8bit First graph-scale liar fixed. Commit walking moves from SyncProtocol into CborPatchJournalAdapter. Domain consumes a stream of PatchEntry instances instead of accumulating an array. The adapter walks the commit DAG backwards, decodes each patch via readPatch(), normalizes context VV, wraps in PatchEntry, and yields in chronological order. SyncProtocol can now consume incrementally via for-await instead of slurping the whole range. CborPatchJournalAdapter gains commitPort for DAG walking.

Domain concept for "data flow over time." Supports `pipe`, `tee`, `mux`, `demux`, `drain`, `reduce`, `forEach`, `collect`. Natural backpressure via `for await`, error propagation via async iterator protocol, cooperative cancellation via `AbortSignal`. +- **Stream transforms** — `CborEncodeTransform`, `CborDecodeTransform`, `GitBlobWriteTransform`, `TreeAssemblerSink`, `IndexShardEncodeTransform` — composable infrastructure pipeline stages for encode → blobWrite → treeAssemble. +- **Artifact record classes** — `CheckpointArtifact` family (`StateArtifact`, `FrontierArtifact`, `AppliedVVArtifact`), `IndexShard` family (`MetaShard`, `EdgeShard`, `LabelShard`, `PropertyShard`, `ReceiptShard`), `PatchEntry`, `ProvenanceEntry`. Runtime-backed domain nouns with constructor validation and `instanceof` dispatch. +- **`PatchJournalPort.scanPatchRange()`** — streaming alternative to `loadPatchRange()`. Returns `WarpStream` for incremental patch consumption. Commit walking moved from SyncProtocol into the adapter. +- **`StateHashService`** — standalone canonical state hash computation. Separately callable by checkpoint creation, comparison, materialization, and verification. +- **Index builder `yieldShards()`** — `LogicalBitmapIndexBuilder` and `PropertyIndexBuilder` yield `IndexShard` record instances via generators. Proven byte-identical to legacy `serialize()` path. +- **`LogicalIndexBuildService.buildStream()`** — returns `WarpStream` merging both builders via `mux()`. +- **Hex tripwire test** — 36 automated checks scanning domain files for forbidden codec imports/usage. Fails loud if domain touches `defaultCodec`, `cbor-x`, or `codec.encode()`/`codec.decode()`. +- **Golden fixtures** — known CBOR bytes for patches, checkpoints, VV, frontier, index shards. Wire format stability proven across refactor. + ### Changed -- **CheckpointStorePort wiring (P5 strangler)** — `CheckpointService`, `CheckpointController`, `MaterializeController`, and `WarpRuntime` now accept an optional `checkpointStore` parameter. When provided, checkpoint create/load operations delegate serialization to the port instead of calling serializers directly. Legacy codec-based paths remain as fallback. `WarpRuntime.open()` auto-constructs a `CborCheckpointStoreAdapter` when no explicit store is provided, matching the `patchJournal` auto-construction pattern. +- **CheckpointStorePort collapsed** — 7 micro-methods (`writeState`, `readState`, etc.) replaced with 2 semantic operations: `writeCheckpoint(record)` and `readCheckpoint(treeOids)`. A checkpoint is one domain event, not a bag of individual blob writes. +- **SyncProtocol uses stream scan** — `processSyncRequest()` prefers `patchJournal.scanPatchRange()` (streaming) over `loadPatchRange()` (array). Falls back to legacy path when unavailable. +- **PatchBuilderV2, SyncProtocol, Writer** — codec-free. Patch persistence goes through `PatchJournalPort`; domain never imports `defaultCodec` or calls `codec.encode()`/`codec.decode()`. +- **CheckpointService** — routes through `CheckpointStorePort` when available. Legacy codec-based paths remain as fallback. - **The Method** — introduced `METHOD.md` as the development process framework. Filesystem-native backlog (`docs/method/backlog/`) with lane directories (`inbox/`, `asap/`, `up-next/`, `cool-ideas/`, `bad-code/`). Legend-prefixed filenames (`PROTO_`, `TRUST_`, `VIZ_`, `TUI_`, `DX_`, `PERF_`). Sequential cycle numbering (`docs/design//`). Dual-audience design docs (sponsor human + sponsor agent). Replaced B-number system entirely. - **Backlog migration** — all 49 B-number and OG items migrated from `BACKLOG/` to `docs/method/backlog/` lanes. Tech debt journal (`.claude/bad_code.md`) split into 10 individual files in `bad-code/`. Cool ideas journal split into 13 individual files in `cool-ideas/`. `docs/release.md` moved to `docs/method/release.md`. `BACKLOG/` directory removed. diff --git a/src/domain/utils/canonicalCbor.js b/src/domain/utils/canonicalCbor.js deleted file mode 100644 index 75ee22cf..00000000 --- a/src/domain/utils/canonicalCbor.js +++ /dev/null @@ -1,36 +0,0 @@ -/** - * Canonical CBOR encoding/decoding. - * - * Delegates to defaultCodec which already sorts keys recursively - * and handles Maps, null-prototype objects, and arrays. - * - * Deterministic output relies on cbor-x's key-sorting behaviour, - * which approximates RFC 7049 Section 3.9 (Canonical CBOR) by sorting - * map keys in length-first lexicographic order.
