Pin acquisition resolves and validates the checkpoint and writes a UUID-named durable pin record under backups/pins//; release removes only the exact owned record and fails closed on identity mismatch. The maintenance lock wraps the existing sibling ownership lock with the same dead-PID reconciliation and live-PID refusal semantics. Add the archive module skeleton: ArchiveError typed error, the six raw-telemetry signal map with event-time columns, and the archive path model with strict ID and range-date validation, recursive symlink rejection, root containment, and a live-data-directory separation guard. Twelve pin and lock tests cover acquire/release, retention protection, identity mismatch, escape refusal, and concurrent-owner rejection. --- apps/cli/src/server/archives/errors.ts | 11 + apps/cli/src/server/archives/paths.ts | 195 ++++++++++++++++++ apps/cli/src/server/archives/signals.ts | 44 ++++ apps/cli/src/server/checkpoints.ts | 113 +++++++++++ apps/cli/test/archive-pins.test.ts | 259 ++++++++++++++++++++++++ 5 files changed, 622 insertions(+) create mode 100644 apps/cli/src/server/archives/errors.ts create mode 100644 apps/cli/src/server/archives/paths.ts create mode 100644 apps/cli/src/server/archives/signals.ts create mode 100644 apps/cli/test/archive-pins.test.ts diff --git a/apps/cli/src/server/archives/errors.ts b/apps/cli/src/server/archives/errors.ts new file mode 100644 index 000000000..4753cc8e7 --- /dev/null +++ b/apps/cli/src/server/archives/errors.ts @@ -0,0 +1,11 @@ +import { Schema } from "effect" + +/** + * An archive operation failure.

Defaults are the measured research baselines (max_threads=1, 10,000-row groups, ~500k rows / ~256 MiB per shard). The parser rejects non-positive or fractional values, a row group larger than a shard, a shard byte budget too small for one row group, a free-space reserve larger than the chunk target, an implausible thread count, and missing roots.

A read helper binds a manifest to its on-disk (signal, range, generation) directory. Add the Parquet shard exporter: one bounded UTC-hour slice per shard, written via SELECT ... INTO OUTFILE FORMAT Parquet directly on the restored scratch chDB (result consumed as a write side effect, never returned into JavaScript). Each shard is validated for row count, byte bound, and SHA-256 before the generation is sealed. Add the generation write lifecycle: acquire maintenance lock, resolve and pin the checkpoint, restore to sacrificial scratch, export bounded shards, validate row counts against the source, durably move the owned building generation into place, atomically select it through the active pointer (reporting supersession while retaining the old generation), append the catalog, release the pin, and remove only owned building output. Free-space preflight runs at operation time. Twenty manifest, pointer, path-model, promotion, supersession, and catalog tests cover the pure and filesystem-level state machine; the full chDB export path is exercised by the native smoke. --- apps/cli/src/server/archives/export.ts | 153 +++++++++ apps/cli/src/server/archives/generation.ts | 350 +++++++++++++++++++++ apps/cli/src/server/archives/manifest.ts | 199 ++++++++++++ apps/cli/test/archive-generation.test.ts | 197 ++++++++++++ apps/cli/test/archive-manifest.test.ts | 201 ++++++++++++ 5 files changed, 1100 insertions(+) create mode 100644 apps/cli/src/server/archives/export.ts create mode 100644 apps/cli/src/server/archives/generation.ts create mode 100644 apps/cli/src/server/archives/manifest.ts create mode 100644 apps/cli/test/archive-generation.test.ts create mode 100644 apps/cli/test/archive-manifest.test.ts diff --git a/apps/cli/src/server/archives/export.ts b/apps/cli/src/server/archives/export.ts new file mode 100644 index 000000000..2d448358c --- /dev/null +++ b/apps/cli/src/server/archives/export.ts @@ -0,0 +1,153 @@ +import { createHash } from "node:crypto" +import { existsSync, readFileSync, statSync } from "node:fs" +import { join } from "node:path" +import type { Chdb } from "../chdb" +import { type ArchiveSignal } from "./signals" + +// Parquet shard export from a restored checkpoint's scratch chDB. +// +// The export runs `SELECT ...

Date: Sun, 28 Jun 2026 09:33:31 -0400 Subject: [PATCH 13/78] feat(cli): archive listing, active parquet paths, and catalog rebuild Add the archive read-side. listActiveGenerations reports the active generation per signal/range with archived row count, shard count, total shard bytes, and the active generation's Parquet shard paths in order. Superseded generations are retained on disk but never appear in listings or active-path output, so late-arrival history cannot be double-counted. A malformed active pointer for one range is skipped without hiding the others, and the pointer file is left untouched. activeParquetPaths resolves the machine-readable DuckDB-ready shard paths for one signal across all sealed ranges in ascending order, excluding superseded generations. rebuildCatalog regenerates the per-signal catalog.jsonl from the authoritative generation manifests, so a truncated or missing catalog is recoverable without rescanning Parquet bytes.

Local telemetry archives extend Maple with **long-term, portable +Parquet storage** exported from immutable checkpoints, queryable independently +with DuckDB — without reloading history into the live store or running a second +always-on database. + +This document is the operator and architecture guide for local archives. It +covers the model, the happy path, every major off-happy-path outcome, and the +independent query path. + +## What archives are (and are not) + +**Are:** + +- Immutable Parquet exports of the six raw telemetry tables from a validated + checkpoint. +- Sealed by fixed UTC day and signal, one generation at a time. +- Independently queryable with DuckDB; portable across machines. +- Crash-safe: an interrupted archive leaves the live store untouched and the + archive in a recoverable state. + +**Are not:** + +- A live export endpoint. v1 archives are created explicitly by an operator. +- Automatic hot-store pruning. Existing chDB TTLs govern the hot store; archives + do not delete from it. +- Archive rehydration into the Maple UI. Historical data is queried in DuckDB, + not reloaded into the dashboard. +- A second always-running database. Archives are files; DuckDB opens them on + demand. + +## Architecture + +```text +Live Maple store (chDB) Archive volume (operator-configured) + data/ / + backups/ logs/ + state.json 2026-06-01/ + snapshots// active.json + backup/ generations// + manifest.json manifest.json + pins//.json shards/00.parquet ... + operations/ catalog.jsonl + quarantine/ traces/ ... + retiring/ building// (in-progress) + quarantine/ (uncertain state) +``` + +### Why checkpoint-restored scratch, not a live copy + +The only proven safe source for an archive is a native chDB checkpoint restored +into sacrificial scratch. A raw copy of the live data directory is unsafe: it +captures an inconsistent on-disk state, may include half-written merges, and +races concurrent ingest. A checkpoint, by contrast, is a validated, consistent +snapshot. Archive export restores one checkpoint into a private scratch chDB +(reusing the same scoped instance that checkpoint validation uses), exports from +it, then removes the scratch. The live store is never opened for export. + +### Why generations supersede instead of deduplicating by TraceId + +There is no universal deduplication key across the six raw tables. `TraceId` is +shared by many spans, may be absent from logs, and does not exist on metrics. An +archive therefore seals a fixed UTC-day range into an immutable **generation**. +Late-arriving telemetry for an already-sealed day creates a **new generation** +that structurally supersedes the old one. The `active.json` pointer atomically +selects the new generation; the old generation is retained on disk but never +returned to listings or queries. This avoids scanning all generations to dedup +and makes each generation independently reproducible. + +### Separation of logical chunks, physical shards, and row groups + +- A **logical chunk** is a provisioning target (the `targetChunkBytes` tuning + value); it is not a hard limit. +- A **physical shard** is one Parquet file, bounded by `maxShardRows` and + `maxShardBytes`. In v1, each shard covers one UTC hour within the sealed day. +- A **Parquet row group** is the unit of compression and parallel decode inside + a shard, sized by `rowGroupRows`. + +All three are configurable and calibratable. + +## Pinning and the maintenance lock + +Archive export holds Maple's **maintenance lock** so it cannot overlap checkpoint +creation, restore, or reset. Inside the lock, it acquires a **persistent pin** +on the source checkpoint so retention cannot delete the snapshot between +resolution and export. A stale pin (e.g. from a crashed archive that never +released it) safely over-retains data rather than risking deletion. The pin is +released after the generation is durable. + +## Commands + +### `maple archive create ` + +Seal one UTC day of one signal into a validated Parquet generation. + +```sh +maple archive create 2026-06-01 traces \ + --data-dir ~/.maple/data \ + --archive-dir /Volumes/External/maple-archive \ + --scratch-root /Volumes/External/maple-scratch +``` + +- ``: the UTC day to seal, as `YYYY-MM-DD`. +- ``: one of `logs`, `traces`, `metrics_sum`, `metrics_gauge`, + `metrics_histogram`, `metrics_exponential_histogram`. +- `--checkpoint-id`: archive from a specific checkpoint instead of the current. +- `--archive-dir` / `--scratch-root`: override the default locations. + +The command resolves and pins the checkpoint, restores it to scratch, exports +bounded Parquet shards, validates row counts and checksums, publishes the +generation manifest, atomically selects it, appends the catalog, releases the +pin, and removes the owned scratch. + +### `maple archive list` + +Report active generations: + +```sh +maple archive list --archive-dir /Volumes/External/maple-archive +maple archive list --format paths --signal traces # machine-readable paths +maple archive list --format json # full JSON +``` + +`--format paths` emits the active generation's Parquet shard paths (excluding +superseded generations) ready for DuckDB's `read_parquet`. + +### `maple archive rebuild ` + +Rebuild a signal's `catalog.jsonl` from the authoritative generation manifests, +recovering from a truncated or missing catalog without rescanning Parquet bytes. + +## The happy path: fresh checkpoint through DuckDB investigation + +1.

Defaults are the +measured research baselines (max_threads=1, 10,000-row groups, ~500k rows / +~256 MiB per shard) — **not universal constants**. A deployment should +calibrate against its checkpoint, archive volume, chDB version, and memory +budget with `maple archive calibrate` (see the calibration section below). + +Every generation manifest records the effective tuning values, so a generation +is reproducible and deployment drift is visible. + +## Off-happy-path outcomes + +| Outcome | What happens | +| ------------------------------------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | +| **Unavailable checkpoint** | `archive create` fails closed; the live store is untouched. No generation is written. | +| **Incompatible checkpoint** (wrong chDB/schema version) | The checkpoint resolver rejects it; no export runs. | +| **Stale pin** | A crashed archive's pin over-retains the checkpoint snapshot safely. Re-running archive create succeeds; the pin from the failed run can be inspected under `backups/pins/`. | +| **Interrupted restore** | The restored scratch is owned by the operation; on failure it is cleaned up. The live store is never modified. | +| **Partial shard** | A shard that exceeds `maxShardRows` or `maxShardBytes` fails closed; the operator recalibrates with a finer split or larger budget. | +| **Validation mismatch** (source vs archived row count) | The generation is not promoted. The building dir is removed (it is owned temp output); no active pointer changes. | +| **Full or disconnected archive volume** | Free-space preflight fails before any export. No scratch is created. | +| **Pointer or catalog corruption** | `archive list` skips a malformed pointer for one range without hiding others. `archive rebuild` regenerates the catalog from manifests. The corrupt files are preserved untouched. | +| **Late telemetry** | A new generation supersedes; the old generation is retained but excluded from active paths. | +| **Interrupted GC** | Not applicable in v1 (no archive GC yet). Checkpoint GC over-retains on uncertainty. | +| **Insufficient memory budget** | Calibration reports low confidence rather than presenting synthetic precision. | +| **Failed calibration** | No config is written; temporary calibration output is cleaned up. | + +### What failures leave untouched vs. require action + +- **Live store untouched by every archive failure.** Export reads only from + restored scratch. +- **Recoverable debris:** interrupted building dirs (owned, removed on retry) and + stale pins (over-retained). +- **Operator intervention:** a persistently corrupt active pointer or a shard + that repeatedly exceeds bounds requires recalibration or manual inspection. + +## Capacity and resource model + +For a 4 GiB hot-store target, live store plus current and previous checkpoints is +roughly 3x the live footprint. Archive export temporarily adds scratch restore +capacity. Checkpoint validation and archive export share **one** sacrificial +chDB, so archive export does not add a second concurrent `f(4)` memory term — +rotation adds duration and disk I/O to that scratch working set, not another +full in-memory OLAP copy. + +The archive volume grows with retained historical ranges. Use volume-specific +free-space measurements in deployment; the `minFreeSpaceReserve` preflight +enforces headroom at operation time. + +> **Capacity caveat:** The research baselines were measured on one macOS ARM64 +> machine with one synthetic data distribution. CPU count, RAM, storage speed, +> row width, cardinality, and compression ratio vary. Operators should +> calibrate their deployment. + +## Non-goals (v1) + +- No live export endpoint. +- No automatic hot-store pruning. +- No archive rehydration into the Maple UI. +- No always-running twin database. +- No automatic archive scheduling (start manual; add scheduling only after + repeated successful runs and measured checkpoint pause). From a931fc5a7fea32c6b2640751a4e839e4013db2cb Mon Sep 17 00:00:00 2001 From: remote service administrator Date: Sun, 28 Jun 2026 10:07:33 -0400 Subject: [PATCH 16/78] feat(cli): native archive smoke and DuckDB acceptance Add native-archive-smoke.sh: ingest markers into all six raw tables, create two checkpoints, archive a sealed UTC day per signal, list active generations, query each archive with DuckDB for exact source counts (2), prove the live store is unchanged after archiving, and rebuild every signal catalog. Two consecutive runs pass. Fix two real defects the smoke exposed: 1. JSONEachRow count parsing. count() results from chDB's FFI path are newline-delimited JSON objects, not a JSON array. The day-count, hour-count, and time-bounds helpers were JSON.parse-ing the whole string as an array and indexing [0], yielding undefined -> 0 rows. Now split on newlines and read the count() column by name, matching the checkpoint module's readJsonRows. 2. Date predicate correctness. chDB's bundled ClickHouse miscounts aggregate count() over a toDateTime64-vs-DateTime predicate (per-row comparison is correct but the aggregate returns zero). Switched all range predicates to toDate()/toHour() equality, which normalizes both second-precision DateTime and nanosecond DateTime64(9) event-time columns. Also rename the archive list format flag from --format to --output to avoid collision with the global --format (json|table) shared flag, and update the docs accordingly. --- apps/cli/src/commands/archive.ts | 10 +- apps/cli/src/server/archives/export.ts | 98 ++++++---- apps/cli/src/server/archives/generation.ts | 34 ++-- apps/cli/test/native-archive-smoke.sh | 171 ++++++++++++++++++ .../content/docs/local-mode/cli-reference.md | 4 +- docs/local-telemetry-archives.md | 10 +- 6 files changed, 269 insertions(+), 58 deletions(-) create mode 100755 apps/cli/test/native-archive-smoke.sh diff --git a/apps/cli/src/commands/archive.ts b/apps/cli/src/commands/archive.ts index e0eb2aa90..2b86c043f 100644 --- a/apps/cli/src/commands/archive.ts +++ b/apps/cli/src/commands/archive.ts @@ -58,7 +58,7 @@ const signalArgument = Argument.string("signal").pipe( Argument.withDescription(`One of: ${ARCHIVE_SIGNALS.map((s) => s.name).join(", ")}`), ) -const formatFlag = Flag.choice("format", ["summary", "paths", "json"]).pipe( +const outputFlag = Flag.choice("output", ["summary", "paths", "json"]).pipe( Flag.withDescription( "Output format: summary (default), paths (machine-readable active Parquet paths), or json", ), @@ -158,18 +158,18 @@ const signalFlag = Flag.optional( export const archiveList = Command.make("list", { archiveDir: archiveDirFlag, - format: formatFlag, + output: outputFlag, signal: signalFlag, }).pipe( Command.withDescription("List active archive generations and their Parquet shard paths"), Command.withHandler( Effect.fnUntraced(function* (a) { const archiveDir = Option.getOrUndefined(a.archiveDir) ?? defaultArchiveDir() - if (a.format === "paths") { + if (a.output === "paths") { const signalOpt = Option.getOrUndefined(a.signal) if (!signalOpt || !isArchiveSignalName(signalOpt)) { return yield* new ArchiveError({ - message: `--format paths requires a signal argument; expected one of ${ARCHIVE_SIGNALS.map((s) => s.name).join(", ")}`, + message: `--output paths requires a signal argument; expected one of ${ARCHIVE_SIGNALS.map((s) => s.name).join(", ")}`, }) } const paths = activeParquetPaths(archiveDir, signalOpt) @@ -177,7 +177,7 @@ export const archiveList = Command.make("list", { return } const listing = listActiveGenerations(archiveDir) - if (a.format === "json") { + if (a.output === "json") { yield* Effect.sync(() => process.stdout.write(`${JSON.stringify(listing, null, 2)}\n`)) return } diff --git a/apps/cli/src/server/archives/export.ts b/apps/cli/src/server/archives/export.ts index 2d448358c..fff7d31d5 100644 --- a/apps/cli/src/server/archives/export.ts +++ b/apps/cli/src/server/archives/export.ts @@ -44,41 +44,70 @@ const HOURS_IN_DAY = Array.from({ length: 24 }, (_, hour) => hour) const shardName = (hour: number): string => `${hour.toString().padStart(2, "0")}.parquet` /** - * Count the rows in `table` for a half-open UTC time range on the signal's - * event-time column.

The calibrator runs a bounded matrix of Parquet writer/row-group/shard candidates against a pinned checkpoint restored into sacrificial scratch, measuring peak RSS, wall time, and output bytes per candidate in a fresh child process (so peak RSS is measured per-candidate, not accumulated in-process). It selects the lowest-RSS candidate within the operator's memory and time budgets, reports high/low confidence, and writes a versioned configuration document only when --write-config is passed (never auto-applies). A native calibration smoke verified the full round-trip: four candidates ran at ~320MB RSS each, the matrix selected writerThreads=1/rowGroupRows=20000 within a 1GB budget with high confidence, and the generated config recorded the measured peak RSS, output bytes, and effective tuning. An impossible budget fails closed with low confidence and no config mutation. Per D-017, true external-volume deployment-scale calibration under the deployment chDB/user/filesystem is a Phase 3 dependency; Phase 2 proves the mechanism and generated-config round-trip on a local scratch volume. --- apps/cli/src/commands/archive.ts | 204 ++++++++++++++- apps/cli/src/server/archives/calibrate.ts | 299 ++++++++++++++++++++++ 2 files changed, 501 insertions(+), 2 deletions(-) create mode 100644 apps/cli/src/server/archives/calibrate.ts diff --git a/apps/cli/src/commands/archive.ts b/apps/cli/src/commands/archive.ts index 2b86c043f..4c27563c8 100644 --- a/apps/cli/src/commands/archive.ts +++ b/apps/cli/src/commands/archive.ts @@ -3,12 +3,14 @@ import * as Command from "effect/unstable/cli/Command" import * as Flag from "effect/unstable/cli/Flag" import * as Argument from "effect/unstable/cli/Argument" import { homedir } from "node:os" -import { join } from "node:path" +import { join, resolve } from "node:path" +import { existsSync, readdirSync, statSync } from "node:fs" import { createArchiveGeneration } from "../server/archives/generation" import { listActiveGenerations, activeParquetPaths, rebuildCatalog } from "../server/archives/listing" import { resolveArchiveTuning, type ArchiveTuningOverrides } from "../server/archives/config" import { ARCHIVE_SIGNALS, isArchiveSignalName } from "../server/archives/signals" import { validateRangeDate } from "../server/archives/paths" +import { calibrate, recommendationToTuning, writeCalibrationConfig } from "../server/archives/calibrate" import { amber, bold, dim, green } from "../lib/style" /** An archive command failure.

Path safety (C-1): - ensurePrivateDirectory now walks each ancestor with lstat BEFORE creating, refusing to cross a symlink at any depth (mkdir -p + final lstat was unsafe). - A sync assertNoSymlinkSync variant is added for the synchronous read-side. - promoteGeneration, appendCatalog, and rebuildCatalog now assert no-symlink on every path they create or overwrite, immediately before use. - assertSafeRealPath verifies type + containment + no-symlink at read/write sites. Strict state binding and fail-closed malformed handling (H-7): - parseArchiveActivePointer binds signal/range to its directory, rejecting a pointer copied or moved to the wrong range. - listActiveGenerations surfaces malformed pointers/manifests as errors instead of silently skipping them, while still listing unaffected ranges. - Catalog entries now carry formatVersion 1. Eight external-sentinel tests prove the escapes are closed: symlinked signal root, catalog, manifest, pointer, and ancestor; outside targets are verified untouched. Malformed-pointer surfacing and pointer-directory binding are tested. --- apps/cli/src/server/archives/generation.ts | 67 +++++- apps/cli/src/server/archives/listing.ts | 58 +++++- apps/cli/src/server/archives/manifest.ts | 20 +- apps/cli/src/server/archives/paths.ts | 102 ++++++++- apps/cli/test/archive-path-safety.test.ts | 231 +++++++++++++++++++++ 5 files changed, 449 insertions(+), 29 deletions(-) create mode 100644 apps/cli/test/archive-path-safety.test.ts diff --git a/apps/cli/src/server/archives/generation.ts b/apps/cli/src/server/archives/generation.ts index d4c2a25aa..bf3f02a69 100644 --- a/apps/cli/src/server/archives/generation.ts +++ b/apps/cli/src/server/archives/generation.ts @@ -14,12 +14,18 @@ import { } from "../checkpoints" import { durableJson, durableRename, durableWrite, syncDirectory, syncTree } from "../durable-files" import { type ArchiveTuning, tuningRecord } from "./config" -import { type ArchiveShardRecord, type ArchiveGenerationManifest } from "./manifest" +import { + type ArchiveShardRecord, + type ArchiveGenerationManifest, + parseArchiveActivePointer, +} from "./manifest" import { activePointerPath, + archiveRoot, assertArchiveRootSeparate, assertNoSymlink, assertRealDirectory, + assertRealFile, buildingGenerationRoot, buildingRoot, catalogPath, @@ -221,12 +227,40 @@ const countSignalRowsForDay = ( signal: ArchiveSignal, rangeDate: string, ): number => { - // Use toDate() equality, not a toDateTime64 range: chDB's bundled ClickHouse + // Use toDate() equality, not a toDateTime64: chDB's bundled ClickHouse // miscounts aggregate count() over a toDateTime64-vs-DateTime predicate. const sql = `SELECT count() FROM ${signal.name} WHERE toDate(${signal.eventTimeColumn}) = '${rangeDate}'` return parseCount(db.query(sql, "JSONEachRow")) } +/** + * Strictly read the previous active pointer and return its generation id, binding + * the pointer's recorded signal/range to its on-disk location so a pointer + * copied or moved to the wrong range cannot be silently superseded (H-7). + * Throws on a malformed, mismatched, or unreadable pointer. + */ +const readPreviousPointerGenerationId = ( + pointerPath: string, + expectedSignal: string, + expectedRange: string, +): string | null => { + const parsed = JSON.parse(readFileSync(pointerPath, "utf8")) as unknown + const pointer = parseArchiveActivePointer(parsed) + if (pointer.signal !== expectedSignal) { + throw new Error( + `archive active pointer signal mismatch at ${pointerPath}: ` + + `expected ${expectedSignal}, recorded ${pointer.signal}`, + ) + } + if (pointer.rangeStart !== expectedRange) { + throw new Error( + `archive active pointer range mismatch at ${pointerPath}: ` + + `expected ${expectedRange}, recorded ${pointer.rangeStart}`, + ) + } + return pointer.generationId +} + /** Parse a JSONEachRow count result (newline-delimited objects, not a JSON array). */ const parseCount = (text: string): number => { const rows = text @@ -244,15 +278,19 @@ const parseCount = (text: string): number => { const ensureOwnedBuilding = async (archiveDir: string, building: string): Promise => { const root = buildingRoot(archiveDir) + // Refuse a symlinked building root or any symlinked ancestor beneath the + // archive root before creating anything (C-1): mkdir -p would otherwise + // silently create the tree under a symlink target outside the archive root. if (existsSync(root)) { await assertNoSymlink(archiveDir, root, "archive building root") await assertRealDirectory(root, "archive building root") } - await ensurePrivateDirectory(root) + await ensurePrivateDirectory(root, archiveRoot(archiveDir)) if (existsSync(building)) { throw new Error(`archive building generation already exists;

Subject: [PATCH 19/78] fix(archives): close read-side symlink escapes (HIGH-1/HIGH-2 from R1 review) The R1 fix closed the C-1 write side but left the read side open: a non-racing attacker who plants one symlinked descendant (generation dir, shard file, or range dir) could make listActiveGenerations/activeParquetPaths/rebuildCatalog follow it out of the archive root, feeding attacker-controlled Parquet to DuckDB and attacker-controlled manifest fields to the catalog. The fix's own guard primitives were written but never wired into read paths. This closes the asymmetry: - readArchiveGenerationManifest (the single chokepoint for manifest reads) now asserts no-symlink + real-file before readFileSync, so a symlinked signal/range/generation/manifest chain is refused. - listActiveGenerations asserts no-symlink on the active-pointer path before reading it and on every shard path before returning it to DuckDB. - The dead assertSafeRealPath helper (never called) is removed. Three read-side sentinel tests prove the escapes are closed: a symlinked generation dir is refused by readArchiveGenerationManifest and rebuildCatalog (the attacker manifest is not trusted); a symlinked shard file is refused by listActiveGenerations and surfaced as an error rather than returned to DuckDB. Outside targets are verified unread. --- apps/cli/src/server/archives/listing.ts | 25 +++++++- apps/cli/src/server/archives/manifest.ts | 18 +++++- apps/cli/src/server/archives/paths.ts | 21 ------- apps/cli/test/archive-path-safety.test.ts | 75 +++++++++++++++++++++++ 4 files changed, 113 insertions(+), 26 deletions(-) diff --git a/apps/cli/src/server/archives/listing.ts b/apps/cli/src/server/archives/listing.ts index c88de4271..3b04d57d6 100644 --- a/apps/cli/src/server/archives/listing.ts +++ b/apps/cli/src/server/archives/listing.ts @@ -90,6 +90,9 @@ export const listActiveGenerations = (archiveDir: string): ArchiveListing => { if (!existsSync(pointerPath)) continue let generationId: string try { + // Refuse a symlinked pointer path (HIGH-1 read-side): a symlinked + // range dir would make this read attacker-controlled content. + assertNoSymlinkSync(archiveDir, pointerPath, "archive active pointer") const pointer = parseArchiveActivePointer( JSON.parse(readFileSync(pointerPath, "utf8")) as unknown, signal.name, @@ -116,6 +119,24 @@ export const listActiveGenerations = (archiveDir: string): ArchiveListing => { continue } signalHasActive = true + // Verify each shard path is not a symlink before returning it to DuckDB + // (HIGH-1 read-side): a planted symlinked shard could feed attacker + // Parquet to the query engine even with a valid manifest. + let shardPaths: string[] + try { + shardPaths = manifest.shards.map((shard) => { + const p = shardFilePath(archiveDir, signal.name, rangeDate, generationId, shard.name) + assertNoSymlinkSync(archiveDir, p, "archive shard") + return p + }) + } catch (error) { + errors.push({ + signal: signal.name, + rangeStart: rangeDate, + error: `shard path: ${messageOf(error)}`, + }) + continue + } active.push({ signal: signal.name, rangeStart: rangeDate, @@ -124,9 +145,7 @@ export const listActiveGenerations = (archiveDir: string): ArchiveListing => { shardCount: manifest.shards.length, createdAt: manifest.createdAt, checkpointId: manifest.checkpointId, - shardPaths: manifest.shards.map((shard) => - shardFilePath(archiveDir, signal.name, rangeDate, generationId, shard.name), - ), + shardPaths, shardBytes: shardBytes(manifest), }) } diff --git a/apps/cli/src/server/archives/manifest.ts b/apps/cli/src/server/archives/manifest.ts index 0f54b56a6..90a29718b 100644 --- a/apps/cli/src/server/archives/manifest.ts +++ b/apps/cli/src/server/archives/manifest.ts @@ -1,9 +1,17 @@ -import { readFileSync } from "node:fs" +import { lstatSync, readFileSync } from "node:fs" import { join } from "node:path" import { type ArchiveTuningRecord } from "./config" -import { generationManifestPath, validateArchiveId, validateRangeDate } from "./paths" +import { assertNoSymlinkSync, generationManifestPath, validateArchiveId, validateRangeDate } from "./paths" import { isArchiveSignalName } from "./signals" +/** Synchronously verify a path is a real (non-symlink) file before reading it. */ +const assertRealFileSync = (path: string, label: string): void => { + const info = lstatSync(path) + if (info.isSymbolicLink() || !info.isFile()) { + throw new Error(`${label} must be a real file: ${path}`) + } +} + // Versioned, strict archive manifest and pointer formats. // // A generation manifest is the authoritative completion record for one sealed @@ -171,6 +179,12 @@ export const readArchiveGenerationManifest = ( generationId: string, ): ArchiveGenerationManifest => { const path = generationManifestPath(archiveDir, signal, rangeDate, generationId) + // Refuse a symlinked descendant on the READ path (the C-1 write fix's mirror): + // a planted symlink on the signal/range/generation/manifest chain would be + // followed by readFileSync, reading attacker-controlled content from outside + // the archive root.

Errors for other signals do not block a clean signal's paths. 2. rebuildCatalog now PREFLIGHTS every manifest before writing. If any generation is missing its manifest, is malformed, or is on a symlinked path, the existing catalog is PRESERVED untouched and the call throws. The old code silently skipped corrupt generations and wrote a partial catalog. 3. Pointer reads now require a real regular file (assertRealFileSync), matching the manifest-read check, so a non-file entry cannot feed undefined content. 4. ensurePrivateDirectory's root parameter is now MANDATORY (was optional and degenerate when omitted). Fresh archive-root creation is repaired: the root is created first before walking children, fixing the ENOENT on a fresh root. assertRealFileSync is moved to paths.ts as a shared sync primitive. Three new tests cover the fail-closed activeParquetPaths (malformed same-signal range throws; different-signal error does not block), rebuild catalog preservation on missing manifest, and fresh-root nested directory creation. --- apps/cli/src/server/archives/generation.ts | 2 +- apps/cli/src/server/archives/listing.ts | 80 ++++++++++++++-------- apps/cli/src/server/archives/manifest.ts | 18 +++-- apps/cli/src/server/archives/paths.ts | 56 +++++++++++---- apps/cli/test/archive-listing.test.ts | 46 ++++++++++++- apps/cli/test/archive-path-safety.test.ts | 16 ++++- 6 files changed, 159 insertions(+), 59 deletions(-) diff --git a/apps/cli/src/server/archives/generation.ts b/apps/cli/src/server/archives/generation.ts index bf3f02a69..d0c90f420 100644 --- a/apps/cli/src/server/archives/generation.ts +++ b/apps/cli/src/server/archives/generation.ts @@ -150,7 +150,7 @@ export const createArchiveGeneration = async ( await faults.afterBuildingCreated?.() const shardsDir = join(building, "shards") - await ensurePrivateDirectory(shardsDir) + await ensurePrivateDirectory(shardsDir, archiveRoot(archiveDir)) const writtenShards = exportSignalShards(db, signal, rangeDate, shardsDir, { writerThreads: tuning.writerThreads, rowGroupRows: tuning.rowGroupRows, diff --git a/apps/cli/src/server/archives/listing.ts b/apps/cli/src/server/archives/listing.ts index 3b04d57d6..21d447263 100644 --- a/apps/cli/src/server/archives/listing.ts +++ b/apps/cli/src/server/archives/listing.ts @@ -9,6 +9,7 @@ import { import { activePointerPath, assertNoSymlinkSync, + assertRealFileSync, catalogPath, generationManifestPath, generationsRoot, @@ -90,9 +91,11 @@ export const listActiveGenerations = (archiveDir: string): ArchiveListing => { if (!existsSync(pointerPath)) continue let generationId: string try { - // Refuse a symlinked pointer path (HIGH-1 read-side): a symlinked - // range dir would make this read attacker-controlled content. + // Refuse a symlinked or non-regular pointer path (HIGH-1 read-side): + // a symlinked range dir or a non-file (socket, device) would make + // this read attacker-controlled or undefined content. assertNoSymlinkSync(archiveDir, pointerPath, "archive active pointer") + assertRealFileSync(pointerPath, "archive active pointer") const pointer = parseArchiveActivePointer( JSON.parse(readFileSync(pointerPath, "utf8")) as unknown, signal.name, @@ -161,9 +164,25 @@ const messageOf = (error: unknown): string => (error instanceof Error ? error.me * ranges, excluding superseded generations.

The prior code aborted if a single hour exceeded the bound instead of splitting. Shard names encode their slice: HH-NNNN.parquet (hour + sequence). R2 — pre-promotion Parquet validation: after writing each shard, it is REOPENED via chDB file(path, Parquet) and its row count, min/max event time, and column list are READ BACK from the Parquet file. A 19-byte invalid 'Parquet' file fails this reopen because file() cannot parse it. The shard record now carries the REOPENED counts and columns, not the source counts — closing the tautology where the record always matched the source query. An empty (0-row) reopen also fails. The ArchiveShardRecord gains a columns field (schema round-trip proof); the manifest parser strictly validates it. Test fixtures updated to the new shard name format and columns field. --- apps/cli/src/server/archives/export.ts | 224 ++++++++++++--------- apps/cli/src/server/archives/generation.ts | 1 + apps/cli/src/server/archives/manifest.ts | 19 +- apps/cli/test/archive-generation.test.ts | 1 + apps/cli/test/archive-listing.test.ts | 1 + apps/cli/test/archive-manifest.test.ts | 3 +- apps/cli/test/archive-path-safety.test.ts | 1 + 7 files changed, 153 insertions(+), 97 deletions(-) diff --git a/apps/cli/src/server/archives/export.ts b/apps/cli/src/server/archives/export.ts index fff7d31d5..0eea86735 100644 --- a/apps/cli/src/server/archives/export.ts +++ b/apps/cli/src/server/archives/export.ts @@ -4,22 +4,23 @@ import { join } from "node:path" import type { Chdb } from "../chdb" import { type ArchiveSignal } from "./signals" -// Parquet shard export from a restored checkpoint's scratch chDB. +// Bounded Parquet shard export from a restored checkpoint's scratch chDB. // // The export runs `SELECT ...

The prior LIMIT/OFFSET without ORDER BY was nondeterministic and could silently duplicate or drop rows. The last shard gets the remainder via min(rowsPerShard, hourRows - offset), and the expected row count is computed and passed to validation. H-A — DESCRIBE file() failures are no longer swallowed. A schema that did not round-trip fails the shard (columns.length === 0 throws), so the manifest's columns field is a real guarantee, not best-effort. H-B — validateShard now checks the reopened row count against the intended slice size AND verifies all rows fall within the expected hour window (toHour(min) === toHour(max) === hour), so a shard containing rows from the wrong hour is rejected. H-C — the byte bound is now enforced on UNCOMPRESSED bytes via parquet_metadata().uncompressed_size, not compressed on-disk size. Compression could previously keep an oversized shard under the compressed ceiling. M-1 — operator paths containing single quotes or backslashes are rejected before export (assertSafePath); both INTO OUTFILE and file() literals use the same sqlLiteral escaping. M-2 — the promoteGeneration test no longer passes a stale 7th argument. --- apps/cli/src/server/archives/export.ts | 128 +++++++++++++++++------ apps/cli/test/archive-generation.test.ts | 1 - 2 files changed, 94 insertions(+), 35 deletions(-) diff --git a/apps/cli/src/server/archives/export.ts b/apps/cli/src/server/archives/export.ts index 0eea86735..eec47e100 100644 --- a/apps/cli/src/server/archives/export.ts +++ b/apps/cli/src/server/archives/export.ts @@ -113,58 +113,109 @@ const sha256File = (path: string): string => { * not copied from the source query — closing the tautology where the shard * record always matched the source count. */ +/** + * Escape a filesystem path for safe embedding in a ClickHouse single-quoted + * string literal.

Strengthen validation to compare against source intent (not just 'parseable'): - captureSourceSchema captures name+type before export; validateShard compares the reopened Parquet schema against it (base type match), so a schema that did not round-trip fails the shard. - validateShard verifies the UTC DATE of all rows (toDate min==max==rangeDate) in addition to the hour window. - estimateBytesPerRow and validateShardBytes now use the corrected chDB APIs. Strengthen manifest strictness (H-7): - sha256 must be 64 hex chars; counts must be safe non-negative integers. - Cross-field: unique shard names, shard-row sum == archivedRowCount, sourceRowCount == archivedRowCount, rangeEndExclusive == next-midnight. - parseShardRecord requires nonempty columns; min <= max event time. Other repairs: - Strict calendar date validation (reject 2026-02-31; JS Date normalizes it). - rangeEndExclusive is now the next midnight (exclusive), not 23:59:59 inclusive. - Free-space preflight checks the actual destination volume (climbs to the closest existing ancestor when the root is missing) and includes working bytes. - rebuildCatalog is async and uses durableWrite (atomic temp+fsync+rename) so an interruption cannot destroy the prior catalog. - Active shard paths are asserted to be real existing regular files. - Pin-release failures are surfaced to stderr, not silently swallowed. 133/133 tests pass; typecheck, lint, format clean. --- apps/cli/src/commands/archive.ts | 9 +- apps/cli/src/server/archives/export.ts | 112 ++++++++++++++++----- apps/cli/src/server/archives/generation.ts | 65 +++++++++--- apps/cli/src/server/archives/listing.ts | 24 +++-- apps/cli/src/server/archives/manifest.ts | 69 ++++++++++--- apps/cli/src/server/archives/paths.ts | 29 +++++- apps/cli/test/archive-generation.test.ts | 2 +- apps/cli/test/archive-listing.test.ts | 19 ++-- apps/cli/test/archive-manifest.test.ts | 4 +- apps/cli/test/archive-path-safety.test.ts | 4 +- 10 files changed, 254 insertions(+), 83 deletions(-) diff --git a/apps/cli/src/commands/archive.ts b/apps/cli/src/commands/archive.ts index 4c27563c8..5235dfbee 100644 --- a/apps/cli/src/commands/archive.ts +++ b/apps/cli/src/commands/archive.ts @@ -8,7 +8,7 @@ import { existsSync, readdirSync, statSync } from "node:fs" import { createArchiveGeneration } from "../server/archives/generation" import { listActiveGenerations, activeParquetPaths, rebuildCatalog } from "../server/archives/listing" import { resolveArchiveTuning, type ArchiveTuningOverrides } from "../server/archives/config" -import { ARCHIVE_SIGNALS, isArchiveSignalName } from "../server/archives/signals" +import { ARCHIVE_SIGNALS, isArchiveSignalName, type ArchiveSignalName } from "../server/archives/signals" import { validateRangeDate } from "../server/archives/paths" import { calibrate, recommendationToTuning, writeCalibrationConfig } from "../server/archives/calibrate" import { amber, bold, dim, green } from "../lib/style" @@ -258,7 +258,12 @@ export const archiveRebuild = Command.make("rebuild", { }) } const archiveDir = Option.getOrUndefined(a.archiveDir) ?? defaultArchiveDir() - const entries = rebuildCatalog(archiveDir, a.signal) + const signalName: ArchiveSignalName = a.signal + const entries = yield* Effect.tryPromise({ + try: () => rebuildCatalog(archiveDir, signalName), + catch: (error) => + new ArchiveError({ message: error instanceof Error ? error.message : String(error) }), + }) yield* Effect.sync(() => process.stdout.write( `${green("✓")} rebuilt ${a.signal} catalog with ${entries.length} generation(s)\n`, diff --git a/apps/cli/src/server/archives/export.ts b/apps/cli/src/server/archives/export.ts index eec47e100..eb74b3618 100644 --- a/apps/cli/src/server/archives/export.ts +++ b/apps/cli/src/server/archives/export.ts @@ -88,10 +88,12 @@ const countRowsForHour = (db: Chdb, signal: ArchiveSignal, rangeDate: string, ho * whether a single hour needs sub-splitting.

Timezone: toDate()/toHour() without an explicit 'UTC' argument used the host session timezone, causing the export query and the validation query to shard by different hours (12 UTC stored, 08 EDT computed). All toDate/toHour calls now pass 'UTC' explicitly in export.ts and generation.ts. 2. Schema normalization: Parquet export strips LowCardinality(...) wrappers and widens DateTime to DateTime64. The schema comparison now unwraps LowCardinality/Nullable and normalizes DateTime to DateTime64 before comparing base types, so legitimate Parquet type transformations pass while real schema loss still fails. 3. Smoke determinism: the insert markers now use toDateTime64(..., 9, 'UTC') at a fixed UTC noon timestamp within RANGE_DATE, so the archive's toDate/toHour predicates find the rows regardless of the host timezone.

For each UTC hour, enumerate the active parts and their _part_offset ranges (freezing the layout into a shard plan). 2. Split each part's offset range into bounded intervals (one Parquet file each). 3. Export each shard via WHERE _part = '' AND _part_offset BETWEEN AND — a physical predicate targeting exact immutable rows, not a relative OFFSET that drifts when parts merge. 4. After all shards for the hour, re-enumerate and verify every planned part still exists with the same row count. If a merge removed or changed any part, the export fails closed. The prior OFFSET approach was confirmed corrupting data: an injected merge between shard queries produced [5,6,7,8,5,6,7,8], omitting [1,2,3,4] while all local validations and the aggregate count passed. The part-interval plan targets exact rows by immutable location, so a merge of a different part cannot affect this shard's rows, and if THIS part merges away, the post-export verifyPartsUnchanged detects it. A multi-part adversarial native probe (native-archive-merge-probe.sh) reproduces the cross-check's corruption scenario and confirms the fix: 2 parts → 2 shards, exact ID match [t0..t7], no duplicates. The dead estimateBytesPerRow is removed; the byte bound is enforced post-write via parquet_metadata uncompressed size. --- apps/cli/src/server/archives/export.ts | 191 ++++++++++++++------ apps/cli/test/native-archive-merge-probe.sh | 115 ++++++++++++ 2 files changed, 253 insertions(+), 53 deletions(-) create mode 100755 apps/cli/test/native-archive-merge-probe.sh diff --git a/apps/cli/src/server/archives/export.ts b/apps/cli/src/server/archives/export.ts index b59dcc76e..b099a740f 100644 --- a/apps/cli/src/server/archives/export.ts +++ b/apps/cli/src/server/archives/export.ts @@ -83,24 +83,6 @@ const countRowsForHour = (db: Chdb, signal: ArchiveSignal, rangeDate: string, ho return parseCount(db.query(sql, "JSONEachRow")) } -/** - * Estimate the uncompressed byte size of one row by sampling.

Merge freeze: exportSignalShards now runs SYSTEM STOP MERGES before enumerating parts and SYSTEM START MERGES in a finally. Without this, a background merge on the restored scratch store changed part names between enumeration, export, and source-interval validation, causing stale-part false failures (and on the old OFFSET approach, silent corruption). The freeze makes the physical layout stable for the entire export. 2. Source-interval validation: validateShard now re-queries the SOURCE table for the same (_part, _part_offset) interval and compares count + nanosecond time bounds (via toUnixTimestamp64Nano(toDateTime64(...))) with the reopened Parquet. This proves each shard contains exactly the source rows for its physical interval — a wrong-but-valid row set can no longer pass. Time bounds use nanosecond comparison to avoid session-timezone string mismatches. 3. Exact schema comparison: compareSchema now enforces exact column count, name, and order (positional match), plus base-type compatibility (LowCardinality/ Nullable unwrapped, DateTime normalized to DateTime64). Extra/dropped/ reordered columns fail closed. Nested type parameters (Map key/value types) are still normalized to the base token — documented as a compatibility limitation. Also: ExportSettings gains an afterShardValidated callback for the adversarial merge-injection probe. The sha256FileSync comment is corrected (reads whole file, not streaming). verifyPartsUnchanged is replaced by verifyHourTotalUnchanged (robust to part-name churn from merges, detects data loss/gain). Two native smokes PASS: six-signal (with source-interval validation on all six tables) and merge-safety (2 parts → 2 shards, exact ID match). 133/133 unit tests. --- .gitignore | 2 + apps/cli/src/server/archives/export.ts | 221 ++++++++++++++++-------- apps/cli/src/server/archives/listing.ts | 3 +- 3 files changed, 151 insertions(+), 75 deletions(-) diff --git a/.gitignore b/.gitignore index a15ba75ba..191bcb60b 100644 --- a/.gitignore +++ b/.gitignore @@ -53,3 +53,5 @@ playwright/.cache/ # local-only Drizzle Studio config pointing at miniflare D1 drizzle.config.local.ts +.18bd7*.bun-build +.[0-9a-f]*.bun-build diff --git a/apps/cli/src/server/archives/export.ts b/apps/cli/src/server/archives/export.ts index 72e32bc03..2f7371d22 100644 --- a/apps/cli/src/server/archives/export.ts +++ b/apps/cli/src/server/archives/export.ts @@ -27,6 +27,13 @@ export interface ExportSettings { readonly rowGroupRows: number readonly maxShardRows: number readonly maxShardBytes: number + /** + * Optional callback invoked after each shard is written and validated, before + * the next shard.

Deterministic under SYSTEM STOP MERGES; handles non-contiguous matching offsets (the round-3 offsets 0/9 layout) naturally. Source re-query binds by PAGE POSITION, not by _part_offset value (offsets repeat per part). - Merge-freeze scope (#2): try begins immediately after a successful STOP MERGES so any later failure restarts merges. - Schema compare (#4): recursive normalize-then-compare using the measured chDB->Parquet transforms (LowCardinality unwrap, DateTime->DateTime64(3), DateTime64(N) UTC add, recurse Map/Array/Nullable). Parameterized inner types survive: Array(UInt64) != Array(String) is now caught. - Complex-value digest (#3): per-shard NULL-safe, DateTime-stable digest over the source slice vs reopened Parquet. Catches a changed map/array/NULL value with identical count and time extrema. Robust to cityHash64 NULL propagation (histogram Min/Max) and bare-DateTime widening. - Byte-aware planning (#5): estimate bytes/row from a probe shard, pass maxShardBytes to the planner so a wide-row hour splits by bytes even under the row limit. - Sealed-range timestamps (#6): bind shard min/max event time to [rangeStart 00:00 UTC, next midnight); reject out-of-range (e.g. 2027 for a 2026 range) and add the complexDigest field to the shard record. 149/149 unit tests; 7/7 native adversarial scenarios; six-signal smoke PASS (6 signals archived, DuckDB exact counts, live store unchanged, catalog rebuilt).

NULL-safe, DateTime-normalized, 41ms/+15MiB at 500k rows (measured). Manifest gains a complexDigestAlgorithm field. - Byte bounds: measure each candidate shard's actual total_uncompressed_size and recursively bisect the physical range when it exceeds maxShardBytes, until every accepted shard meets both bounds. The only impassable case — a single matching row whose size alone exceeds the bound — fails distinctly. Sampling no longer determines correctness. - UTC time evidence: replace timezone-less ISO strings parsed with Date.parse (host-timezone-dependent: a valid 23:30 UTC bound was rejected as next-day under America/New_York) with min/max event time as UTC epoch-NANOSECOND decimal strings parsed with BigInt. Manifest format version bumped 1 -> 2; a v1 manifest fails closed with a distinct message (preserved, not migrated). - Export query: no ORDER BY (D-016). Page each MergeTree part's _part_offset domain into half-open ranges; offset holes are excluded by the UTC date/hour predicate, and counts derive from actual matching rows. Each defect was first reproduced by a failing probe (red baseline), then the fix turned it green. 147/147 unit tests; 15/15 adversarial probes (incl. the independent DuckDB oracle confirming read-back fidelity of counts, nanosecond timestamps, NULLs, and arrays); six-signal native smoke, merge-injection, and merge-safety probes pass.

Lifecycle boundaries (each a recorded durable phase, journal never ahead of the filesystem): intent -> pin -> scratch -> restore -> building -> shards -> manifest -> promote -> pointer (CAS-guarded) -> catalog -> pin-release -> scratch-remove -> complete. promoteGeneration now only moves+writes the manifest; selectActiveGeneration flips the pointer only if it equals the recorded base or already selects the intended generation (no clobbering of concurrent activity). Reconciliation: at most one active op; pre-publication ops quarantine incomplete building (retained, D-004), remove only owned scratch, release only the owned pin; post-promotion ops finish pointer/catalog then clean up. Idempotent (a second reconcile converges to the same state). The finally handles only thrown errors; the journal is authoritative for SIGKILL recovery. selectActiveGeneration is CAS-guarded and idempotent. Tests cover promotion split, CAS refusal, idempotence, and the journal's fail-closed parsing (unknown format version, invalid phase, scratch-subdir escape, identity mismatch, multi-op refusal, malformed intent). --- apps/cli/src/server/archives/generation.ts | 434 ++++++++++++++++++-- apps/cli/src/server/archives/journal.ts | 456 +++++++++++++++++++++ apps/cli/test/archive-generation.test.ts | 49 ++- apps/cli/test/archive-journal.test.ts | 193 +++++++++ 4 files changed, 1091 insertions(+), 41 deletions(-) create mode 100644 apps/cli/src/server/archives/journal.ts create mode 100644 apps/cli/test/archive-journal.test.ts diff --git a/apps/cli/src/server/archives/generation.ts b/apps/cli/src/server/archives/generation.ts index 9af0b16a6..f79003d12 100644 --- a/apps/cli/src/server/archives/generation.ts +++ b/apps/cli/src/server/archives/generation.ts @@ -1,11 +1,12 @@ import { randomUUID } from "node:crypto" import { existsSync, readFileSync } from "node:fs" import { rm, statfs } from "node:fs/promises" -import { dirname, join, resolve } from "node:path" +import { dirname, join, relative, resolve, sep } from "node:path" import { CHDB_VERSION, MAPLE_VERSION } from "../../version" import { SCHEMA_FINGERPRINT } from "../serve" import { acquireCheckpointPin, + checkpointPinsRoot, releaseCheckpointPin, resolveCheckpoint, withMaintenanceLock, @@ -39,6 +40,20 @@ import { } from "./paths" import { type ArchiveSignal, archiveSignal } from "./signals" import { COMPLEX_DIGEST_ALGORITHM, exportSignalShards, type WrittenShard } from "./export" +import { + advancePhase, + archiveCompletedOperation, + assertPointerConsistent, + operationDir, + ownedPathsFor, + phaseAtLeast, + readActiveOperation, + resolveBaseActiveGenerationId, + writeInitialIntent, + type ArchiveOperationIntent, + type ArchiveOperationPhase, +} from "./journal" +import { rebuildCatalog } from "./listing" // Archive generation write, validation, promotion, and reconciliation. // @@ -65,6 +80,23 @@ export interface ArchiveGenerationFaults { readonly afterCatalogAppended?: () => void | Promise readonly afterPinReleased?: () => void | Promise readonly afterBuildingRemoved?: () => void | Promise + // Pre-boundary seams for crash-safety validation (Gate 3).

Plus a cross-cutting check that a fresh 'archive create' reconciles an interrupted op as its first locked step before allocating. Hook-throw results cannot substitute for this oracle: a thrown error runs the finally (releasing the pin/removing debris) while SIGKILL does not, so only a real kill proves the journal — not the finally — is the crash-recovery authority. The adversarial matrix gains a 'Crash recovery' section (invariant 9) recording every kill-point, the SIGKILL-vs-hook fidelity classification, the oracle, and the required recovery result, with the working rule answered per row. --- apps/cli/test/archive-adversarial-matrix.md | 48 +++ .../native-archive-crash-recovery-probe.sh | 340 ++++++++++++++++++ apps/cli/test/probes/archive-crash-worker.ts | 187 ++++++++++ .../test/probes/archive-reconcile-worker.ts | 43 +++ 4 files changed, 618 insertions(+) create mode 100644 apps/cli/test/native-archive-crash-recovery-probe.sh create mode 100644 apps/cli/test/probes/archive-crash-worker.ts create mode 100644 apps/cli/test/probes/archive-reconcile-worker.ts diff --git a/apps/cli/test/archive-adversarial-matrix.md b/apps/cli/test/archive-adversarial-matrix.md index 244699c80..69239b691 100644 --- a/apps/cli/test/archive-adversarial-matrix.md +++ b/apps/cli/test/archive-adversarial-matrix.md @@ -148,6 +148,54 @@ unavailable.

A crashed GC shares the single operations/active/ slot, so it MUST reconcile or it blocks all future archive work. planArchiveGc enumerates superseded generations under the maintenance lock and builds a frozen deletion set: --keep N (default 1) retains the newest N superseded per range; the active generation is never selected; a signal whose catalog cannot be authoritatively reconstructed is excluded ENTIRELY before any mutation (never delete a range then discover reconstruction is impossible); malformed/symlinked/ambiguous state fails toward over-retention. Collection is crash-safe via tombstone rename — never in-place recursive delete: each target is atomically renamed source→tombstone (manifest intact, no half-deleted window), then only the journal-owned tombstone is removed. A SIGKILL mid-collection leaves whole owned state that reconcile proves it owns. Each target revalidates the pointer (CAS — must equal the recorded active, not merely 'some other gen') and the source (manifest SHA + per-shard SHA) before rename; a pointer that came back onto a target stops collection and preserves it.

Adds a red() style helper for the over-retention/excluded warning lines. --- apps/cli/src/commands/archive.ts | 121 ++++++++++++++++++++++++++++++- apps/cli/src/lib/style.ts | 1 + 2 files changed, 120 insertions(+), 2 deletions(-) diff --git a/apps/cli/src/commands/archive.ts b/apps/cli/src/commands/archive.ts index 5235dfbee..08e597ebf 100644 --- a/apps/cli/src/commands/archive.ts +++ b/apps/cli/src/commands/archive.ts @@ -5,13 +5,14 @@ import * as Argument from "effect/unstable/cli/Argument" import { homedir } from "node:os" import { join, resolve } from "node:path" import { existsSync, readdirSync, statSync } from "node:fs" -import { createArchiveGeneration } from "../server/archives/generation" +import { createArchiveGeneration, reconcileArchiveGeneration } from "../server/archives/generation" import { listActiveGenerations, activeParquetPaths, rebuildCatalog } from "../server/archives/listing" +import { runArchiveGc } from "../server/archives/gc" import { resolveArchiveTuning, type ArchiveTuningOverrides } from "../server/archives/config" import { ARCHIVE_SIGNALS, isArchiveSignalName, type ArchiveSignalName } from "../server/archives/signals" import { validateRangeDate } from "../server/archives/paths" import { calibrate, recommendationToTuning, writeCalibrationConfig } from "../server/archives/calibrate" -import { amber, bold, dim, green } from "../lib/style" +import { amber, bold, dim, green, red } from "../lib/style" /** An archive command failure.

GC state machine: introduce a nonterminal gc-collecting phase (allows a full cursor — the legitimate post-final-deletion state). Progress is persisted as gc-collecting per target, NEVER complete. complete is written only after all targets are absent + every affected catalog passes assertCatalogExact. Fixes the premature-complete defect where reconcile archived a journal mid-collection. 2. Terminal invariant proof: a complete GC journal is verified before archival (completedTargets === targets.length, every target source + tombstone absent, every affected pointer unchanged, every catalog exact). A failed invariant preserves the active journal (fail closed). reconcileGcOperation re-reads the durable record (not the stale in-memory cursor) before verifying. 3. Phase-strict parser: the v3 union rejects kind-incompatible phases (a GC intent at pin-acquired), aborted for GC, and inconsistent phase/cursor combinations (complete requires a full cursor; intent requires cursor 0). Duplicate-target detection. 4. Locked explicit reconcile: runArchiveReconciliation acquires the maintenance lock before migrating/reconciling; the CLI calls only this (no racing create/GC planning, v2 migration, or pointer/catalog repair). 5. Nonmutating dry-runs: a shared planArchiveReconciliation planner is consumed by both dry-run and apply. gc --dry-run never reconciles (the reconcile-first call is apply-only); if an active op is present, dry-run reports the blocker rather than predicting a deletion set from unstable state. planArchiveReconciliation inspects journals WITHOUT migrating (migration is an apply action). 6. Missing pointers fail closed: a range with no active pointer is uncertain — excluded entirely, nothing targeted, no empty-string sentinel that strands the journal. 7. Faithful crash boundary: a dedicated awaited afterTargetProgress(index, total) seam replaces the duplicate during-removal label; the nonfinal-progress boundary (index < total-1) now exposes the premature-complete defect. The oracle verifies EXACT active/pointer/frozen-target/journal/catalog state after CLI reconcile. --- apps/cli/src/commands/archive.ts | 35 +++- apps/cli/src/server/archives/gc.ts | 194 ++++++++++++++++---- apps/cli/src/server/archives/generation.ts | 134 +++++++++++++- apps/cli/src/server/archives/journal.ts | 59 ++++++ apps/cli/test/archive-adversarial-matrix.md | 79 ++++---- apps/cli/test/archive-gc.test.ts | 150 ++++++++++++++- apps/cli/test/archive-journal.test.ts | 84 +++++++++ apps/cli/test/native-archive-gc-probe.sh | 81 ++++++-- apps/cli/test/probes/archive-gc-worker.ts | 21 ++- 9 files changed, 734 insertions(+), 103 deletions(-) diff --git a/apps/cli/src/commands/archive.ts b/apps/cli/src/commands/archive.ts index 08e597ebf..aa171789c 100644 --- a/apps/cli/src/commands/archive.ts +++ b/apps/cli/src/commands/archive.ts @@ -5,7 +5,7 @@ import * as Argument from "effect/unstable/cli/Argument" import { homedir } from "node:os" import { join, resolve } from "node:path" import { existsSync, readdirSync, statSync } from "node:fs" -import { createArchiveGeneration, reconcileArchiveGeneration } from "../server/archives/generation" +import { createArchiveGeneration, runArchiveReconciliation } from "../server/archives/generation" import { listActiveGenerations, activeParquetPaths, rebuildCatalog } from "../server/archives/listing" import { runArchiveGc } from "../server/archives/gc" import { resolveArchiveTuning, type ArchiveTuningOverrides } from "../server/archives/config" @@ -298,12 +298,27 @@ export const archiveReconcile = Command.make("reconcile", { Command.withHandler( Effect.fnUntraced(function* (a) { const { dataDir, archiveDir, scratchRoot } = resolveRoots(a.dataDir, a.archiveDir, a.scratchRoot) + // Both dry-run and apply go through the locked runArchiveReconciliation + // entry point (blocker 2): dry-run returns the plan without mutating; + // apply acquires the maintenance lock, migrates any v2 intent, then + // reconciles — never racing create/GC planning or pointer/catalog repair. + const plan = yield* Effect.tryPromise({ + try: () => runArchiveReconciliation(dataDir, archiveDir, scratchRoot, { dryRun: a.dryRun }), + catch: (error) => + new ArchiveError({ message: error instanceof Error ? error.message : String(error) }), + }) if (a.dryRun) { yield* Effect.sync(() => process.stdout.write( - `${amber("◌")} dry-run reconcile: would converge an interrupted create or gc operation\n` + - ` ${dim("archive")} ${prettyPath(archiveDir)}\n` + - ` ${dim("note")} no archive state is modified\n`, + `${amber("◌")} dry-run reconcile: ${plan.summary}\n` + + (plan.operationId ? ` ${dim("operation")} ${plan.operationId}\n` : "") + + (plan.kind ? ` ${dim("kind")} ${plan.kind}\n` : "") + + (plan.phase ? ` ${dim("phase")} ${plan.phase}\n` : "") + + ` ${dim("archive")} ${prettyPath(archiveDir)}\n` + + ` ${dim("note")} no archive state is modified\n` + + (plan.blockers.length > 0 + ? plan.blockers.map((b) => ` ${dim("blocker")} ${b}`).join("\n") + "\n" + : ""), ), ) return @@ -313,13 +328,13 @@ export const archiveReconcile = Command.make("reconcile", { `${amber("⟳")} reconciling interrupted archive operation in ${prettyPath(archiveDir)}\n`, ), ) - yield* Effect.tryPromise({ - try: () => reconcileArchiveGeneration(dataDir, archiveDir, scratchRoot), - catch: (error) => - new ArchiveError({ message: error instanceof Error ? error.message : String(error) }), - }) yield* Effect.sync(() => - process.stdout.write(`${green("✓")} reconcile complete (no active operation remains)\n`), + process.stdout.write( + `${green("✓")} reconcile complete: ${plan.summary}\n` + + (plan.blockers.length > 0 + ? `${red("!")} ${plan.blockers.length} blocker(s): ${plan.blockers.join("; ")}\n` + : ""), + ), ) }), ), diff --git a/apps/cli/src/server/archives/gc.ts b/apps/cli/src/server/archives/gc.ts index 96a79ae9c..5594ab464 100644 --- a/apps/cli/src/server/archives/gc.ts +++ b/apps/cli/src/server/archives/gc.ts @@ -24,8 +24,8 @@ import { archiveSignal, type ArchiveSignalName, ARCHIVE_SIGNALS } from "./signal import { archiveCompletedOperation, operationDir, - phaseAtLeast, persistGcProgress, + readActiveOperation, writeGcIntent, type GcOperationIntent, type GcTarget, @@ -98,15 +98,25 @@ export interface GcPlan { /** * Fault seams for crash-safety validation (Gate 3b).

Apply ALWAYS acquires the maintenance lock FIRST, then re-plans under it — never returns success for unsafe state without locking. 2. Valid v2 migration is an ACTION (migrate + reconcile), not a blocker. The planner reports needsMigration=true; apply migrates under the lock. A corrupt v2 intent is fail-closed (will not migrate). 3. Malformed/ambiguous/unreadable/unknown-debris state FAILS CLOSED (throws) — never reported as successful reconciliation. listActiveOperationIdsSafe (which silently filtered debris into absence) is replaced by a strict enumerator that surfaces unknown entries and read errors. 4. dry-run and apply share ONE strict nonmutating planner using the authoritative journal reader (parseArchiveOperationIntent), so the plan apply consumes is the same validated plan dry-run reports — no shallow raw reads. 5. Oracle tightened: a missing catalog fails (not skipped); the completed GC journal's target IDs are compared with the pre-crash frozen set (never re-expanded). Adds archive-reconcile.test.ts (8 tests) covering the locked-wrapper contract: v2-through-wrapper, malformed/multi/debris fail-closed, corrupt-v2 fail-closed, dry-run nonmutation with a v2 intent, apply-throws-on-unsafe, no-op success. --- apps/cli/src/commands/archive.ts | 11 +- apps/cli/src/server/archives/generation.ts | 200 +++++++++++++++----- apps/cli/test/archive-adversarial-matrix.md | 32 ++-- apps/cli/test/archive-reconcile.test.ts | 178 +++++++++++++++++ apps/cli/test/native-archive-gc-probe.sh | 14 +- 5 files changed, 368 insertions(+), 67 deletions(-) create mode 100644 apps/cli/test/archive-reconcile.test.ts diff --git a/apps/cli/src/commands/archive.ts b/apps/cli/src/commands/archive.ts index aa171789c..f60e07425 100644 --- a/apps/cli/src/commands/archive.ts +++ b/apps/cli/src/commands/archive.ts @@ -314,11 +314,16 @@ export const archiveReconcile = Command.make("reconcile", { (plan.operationId ? ` ${dim("operation")} ${plan.operationId}\n` : "") + (plan.kind ? ` ${dim("kind")} ${plan.kind}\n` : "") + (plan.phase ? ` ${dim("phase")} ${plan.phase}\n` : "") + + (plan.needsMigration + ? ` ${dim("action")} migrate legacy v2 intent to v3 then reconcile\n` + : "") + ` ${dim("archive")} ${prettyPath(archiveDir)}\n` + ` ${dim("note")} no archive state is modified\n` + - (plan.blockers.length > 0 - ? plan.blockers.map((b) => ` ${dim("blocker")} ${b}`).join("\n") + "\n" - : ""), + (plan.failClosed + ? ` ${red("!")} FAIL CLOSED: ${plan.failClosed}\n` + : plan.blockers.length > 0 + ? plan.blockers.map((b) => ` ${dim("blocker")} ${b}`).join("\n") + "\n" + : ""), ), ) return diff --git a/apps/cli/src/server/archives/generation.ts b/apps/cli/src/server/archives/generation.ts index 9a2dd0546..d699b9355 100644 --- a/apps/cli/src/server/archives/generation.ts +++ b/apps/cli/src/server/archives/generation.ts @@ -46,12 +46,15 @@ import { archiveCompletedOperation, assertPointerConsistent, migrateActiveIntentIfLegacy, + migrateV2CreateIntent, operationDir, ownedPathsFor, + parseArchiveOperationIntent, phaseAtLeast, readActiveOperation, resolveBaseActiveGenerationId, writeInitialIntent, + type ArchiveOperationIntent, type ArchiveOperationPhase, type CreateOperationIntent, } from "./journal" @@ -1100,43 +1103,70 @@ export interface ReconciliationPlan { readonly phase: string | null readonly summary: string readonly blockers: ReadonlyArray + readonly needsMigration: boolean + readonly failClosed: string | null } +const noActivePlan = (): ReconciliationPlan => ({ + hasActiveOperation: false, + operationId: null, + kind: null, + phase: null, + summary: "no active operation", + blockers: [], + needsMigration: false, + failClosed: null, +}) + /** - * Plan reconciliation WITHOUT mutating: read the (at most one) active operation, - * describe its kind/phase + the convergence outcome + any blockers.

Reads v2 in-memory (no write); returns no-op | fail-closed | a validated snapshot. DELETE the parallel listActiveOperationIdsStrict + shallow planArchiveReconciliation reader from generation.ts. 2. migrateActiveIntentIfLegacy consumes the inspector: all pre-write checks (no-symlink, real-file, directory/record binding, clean v2 lift) run BEFORE any durableJson write. A symlinked intent, a mismatched ID, or a corrupt v2 record is detected before mutation. Closes the v2-mutates-before-detecting-identity/symlink blockers at the mutation site (defense in depth). 3. Concrete discriminated-union plan (ReconciliationPlan = no-op | fail-closed | create | gc) with EXACT ordered actions (CreateAction/GcAction) and preconditions. No opaque reconcile-create/reconcile-gc rediscovery: buildCreatePlan/buildGcPlan make the branch decision ONCE from observed topology; the executor dispatches per-action via named helpers, revalidating each precondition before mutation. 4. One locked protocol: both dry-run and apply acquire the maintenance lock before inspection; dry-run performs NO mutation (no migration, no reconcile) and a fail-closed plan returns NONZERO; apply executes only the planned actions and captures the terminal postcondition WHILE HOLDING THE LOCK (no post-unlock re-plan → no reporting TOCTOU). Adds state-space tests: v2/v3 × valid/mismatch/symlink/debris × dry-run/apply, lock contention (live owner blocks dry-run), symlinked-intent outside-target survival through both modes, v2-mismatch-never-rewritten-before-rejection. --- apps/cli/src/commands/archive.ts | 42 +- apps/cli/src/server/archives/gc.ts | 8 + apps/cli/src/server/archives/generation.ts | 460 +++++++++++---------- apps/cli/src/server/archives/journal.ts | 400 ++++++++++++++++-- apps/cli/test/archive-journal.test.ts | 2 +- apps/cli/test/archive-reconcile.test.ts | 217 +++++++--- 6 files changed, 815 insertions(+), 314 deletions(-) diff --git a/apps/cli/src/commands/archive.ts b/apps/cli/src/commands/archive.ts index f60e07425..d7cee2659 100644 --- a/apps/cli/src/commands/archive.ts +++ b/apps/cli/src/commands/archive.ts @@ -307,40 +307,38 @@ export const archiveReconcile = Command.make("reconcile", { catch: (error) => new ArchiveError({ message: error instanceof Error ? error.message : String(error) }), }) + const renderPlan = (p: typeof plan): string => { + if (p.kind === "no-op") return `${green("✓")} reconcile: no active operation\n` + if (p.kind === "fail-closed") return `${red("!")} FAIL CLOSED: ${p.reason}\n` + const actionLines = ("actions" in p ? p.actions : []) + .map((a) => ` ${dim("action")} ${"to" in a ? `${a.type} → ${a.to}` : a.type}`) + .join("\n") + return `${plan.kind === "fail-closed" ? red("!") : green("✓")} reconcile ${p.kind}: ${p.operationId}\n${actionLines}${actionLines ?

No I/O, no mutation. Both dry-run and apply will consume the SAME ReconciliationDecision; there is no second if-phase implementation to diverge (the defect that recurred across rounds 2–4). inspectReconciliationState (to follow in the wiring commit) will produce a ReconciliationInspection = null | FailClosed | ValidSnapshot, so validation failures (root/pin/scratch/pointer-CAS/owned-path/identity) enter the SAME decision function as valid state — every unsafe state is decided uniformly. The decision union: NoOp | FailClosed | CreateVerifyComplete | CreateAbortPrepublication | CreateFinishPublication | GcVerifyComplete | GcResume. Each carries exact identities (operationId, journalDigest), observed preconditions, affected signals/targets, and migrationRequired. Uses the canonical PHASE_ORDER/phaseAtLeast from journal.ts (no duplicated sequence). Includes the building+final impossible-topology gate. Preserves the lifted v2 record's exact phase (a v2 record can hold any create-eligible phase, not just intent). Exports PHASE_ORDER from journal.ts for reuse. 21 exhaustive transition-table tests cover every (kind, phase, topology) row and every FailClosed gate, asserting the exact decision. Post-promotion is always CreateFinishPublication (unconditional repair — selectActiveGeneration + rebuildCatalog — NOT phase-conditional verify). Complete phases are verify-only. Multi-signal GC carries explicit affectedSignals. --- apps/cli/src/server/archives/journal.ts | 2 +- apps/cli/src/server/archives/reconcile.ts | 239 ++++++++++++++ .../test/archive-reconcile-decision.test.ts | 299 ++++++++++++++++++ 3 files changed, 539 insertions(+), 1 deletion(-) create mode 100644 apps/cli/src/server/archives/reconcile.ts create mode 100644 apps/cli/test/archive-reconcile-decision.test.ts diff --git a/apps/cli/src/server/archives/journal.ts b/apps/cli/src/server/archives/journal.ts index 62f215039..3e68d531d 100644 --- a/apps/cli/src/server/archives/journal.ts +++ b/apps/cli/src/server/archives/journal.ts @@ -82,7 +82,7 @@ export const ARCHIVE_OPERATION_PHASES = [ ] as const export type ArchiveOperationPhase = (typeof ARCHIVE_OPERATION_PHASES)[number] -const PHASE_ORDER: Readonly> = Object.fromEntries( +export const PHASE_ORDER: Readonly> = Object.fromEntries( ARCHIVE_OPERATION_PHASES.map((phase, index) => [phase, index]), ) as Readonly> diff --git a/apps/cli/src/server/archives/reconcile.ts b/apps/cli/src/server/archives/reconcile.ts new file mode 100644 index 000000000..ababb195b --- /dev/null +++ b/apps/cli/src/server/archives/reconcile.ts @@ -0,0 +1,239 @@ +// The single reconciliation decision engine (Gate 3b r5). +// +// ONE pure transition-table function (`decideReconciliation`) consumes a +// validated snapshot (or a fail-closed/no-op inspection result) and returns a +// `ReconciliationDecision`.

Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Wire the pure decideReconciliation as the SOLE branch logic, deleting the parallel r4 action engine entirely. All reconciliation now flows through one path: inspectReconciliationState → decideReconciliation → execute branch via proven helpers - inspectReconciliationState: runs inspectActiveOperation (symlink-safe V2/V3 inspector) + the full proven validation (assertReconciliationRoots, validateReconciliationTopology, validateOwnedPinState). Any failure → FailClosed (zero mutation). For v2, lifts in-memory preserving the EXACT phase. Returns a complete validated ReconciliationSnapshot. - decideReconciliation: the ONE pure transition table (no I/O). Maps the snapshot to NoOp | FailClosed | CreateVerifyComplete | CreateAbortPrepublication | CreateFinishPublication | GcVerifyComplete | GcResume. - reconcileArchiveGenerationUnderLock: inspect → decide → (dry-run: return; apply: migrate-v2 if needed, then execute via the proven reconcileArchiveGeneration, capture postcondition under lock). - runArchiveReconciliation (CLI): acquires the lock, calls the under-lock function. FailClosed → nonzero in both modes.

It inspects → decides → switches on the computed ReconciliationDecision, executing ONLY the branch-specific helpers for that decision. The decision IS the operative state machine. All three entry points (CLI, automatic create, automatic GC) call this same function — there is one call graph, one decision function, one executor. The inspection now includes branch-significant read-only preconditions: - create post-promotion: verifyPublishedGeneration (manifest SHA + shards); - create terminal: verifyCompletedOperationInvariants; - GC: assertReconciliationRoots + verifyCompletedGcInvariants for complete. So dry-run returns FailClosed for the same state apply rejects (only for valid topology; impossible topologies are gated by the decision function from snapshot fields before any branch-specific verification runs). 238/238 tests pass. 0 lint.

Create post-promotion inspection now includes assertPointerConsistent — a conflicting pointer is FailClosed in dry-run AND apply (parity). 2. GC resume preflight: preflightGcTargets validates EVERY remaining target's source/tombstone topology, manifest/shard evidence, pointer CAS, and both-present detection read-only before the decision authorizes any mutation. Prevents partial deletion where target 1 succeeds but target 2 fails. 3. GC executor split: GcVerifyComplete → verifyCompleteAndArchiveGc (verify + archive, no repair); GcResume → resumeFrozenTargetsAndCompleteGc (resume + complete + verify + archive). The executor dispatches directly to each — no phase re-branch. The decision IS operative for GC as well as create. 4. Destination collision preflight: completed-op dir + quarantine dir existence checked in inspection before the decision authorizes earlier actions.

charset=UTF-8 Content-Transfer-Encoding: 8bit Complete the round-7 GC preflight gaps: 1. preflightGcTargets now validates the ENTIRE frozen set: - prefix (index < cursor): source absent, tombstone absent, pointer CAS; - current/suffix (index >= cursor): all documented crash topologies with evidence validation. Prevents partial deletion when a prefix target is corrupted but suffix targets are valid. 2. revalidateTombstone: for source-absent/tombstone-present targets, proves the tombstone is a real non-symlinked directory with manifest/shard evidence matching the frozen set. A symlinked or tampered tombstone → FailClosed before any mutation. 3. Collision probes replaced with lstatSync-based pathExistsIncludingSymlinks: catches broken/dangling symlinks at deterministic destinations that existsSync misses. Adds two GC multi-target hostile parity tests: - cursor-ahead (completedTargets=1 but target 0 source exists): dry-run FailClosed, apply nonzero, zero mutation (byte-identical snapshot). - source-absent/tombstone-present with symlinked tombstone: dry-run FailClosed, apply nonzero. 241/241 tests. 0 lint.

(Gate 3b r9) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Close the three round-8 bounded defects: 1. Replace ALL existsSync source/tombstone topology checks in gc.ts with a shared lstat-aware tri-state classifier (classifyPath): absent only on ENOENT; real-directory/real-file validated; symlink or non-ENOENT error → fail closed. Used in preflightGcTargets, collectOneTarget, and verifyCompletedGcInvariants. Dangling symlinks are no longer treated as absent. 2. Enforce distinct prefix/current/suffix topology in preflightGcTargets: - prefix (i < cursor): source absent, tombstone absent, pointer CAS; - current (i === cursor): documented crash topologies (source/tomb states); - suffix (i > cursor): source-present + tombstone-absent + evidence + CAS only. A suffix target that is already absent or tombstoned → FailClosed (impossible out-of-order mutation). 3. pathExistsIncludingSymlinks: returns false ONLY on ENOENT; every other lstat error propagates as fail-closed (permission, I/O, malformed path). Adds three hostile parity tests with complete durable-state snapshots: - dangling source symlink → FailClosed, zero mutation (byte-identical); - dangling tombstone symlink → FailClosed, zero mutation; - impossible suffix (target 2 absent while cursor=0) → FailClosed, zero mutation. 244/244 tests. 0 lint.

Because the paths are derived, a crash +between pin creation and the phase advance (when the record still shows +`pinPath: null`) still releases the exact pin.

An archived day is a set of immutable +Parquet files, sealed once, that any DuckDB can read. + +## What this is + +- Export of the **six raw telemetry tables** (`logs`, `traces`, `metrics_sum`, + `metrics_gauge`, `metrics_histogram`, `metrics_exponential_histogram`) from a + validated checkpoint into Parquet, sealed by fixed UTC day and signal. +- A generation model where each sealed day is an immutable **generation**; late + telemetry creates a newer generation that supersedes, selected atomically by an + `active.json` pointer. +- A **calibration** workflow that measures export behavior on the deployment's + hardware and emits a versioned, SHA-256-bound tuning config. +- Crash-safe operation throughout: every mutation is journaled, every + interruption reconciles to its intended state without touching the live store, + and a single pure decision function owns all branch logic. +- A conservative **garbage collector** that reclaims superseded generations by + tombstone-rename with terminal-invariant proofs. +- Full operator/architecture documentation (`docs/local-telemetry-archives.md`). + +## Why each major choice was made + +**Checkpoint-restored scratch, not a live copy.** A raw copy of the live data +directory is unsafe: it captures an inconsistent on-disk state, may include +half-written merges, and races concurrent ingest. The only proven safe source is +a native chDB checkpoint restored into sacrificial scratch. Export restores one +checkpoint into a private scratch chDB (the same scoped instance checkpoint +validation uses), exports from it, then removes the scratch. The live store is +never opened for export. This is also why export holds the maintenance lock: it +shares the one sacrificial chDB with checkpoint operations and must serialize. + +**Generations supersede; we do not deduplicate by `TraceId`.** There is no +universal deduplication key across the six raw tables — `TraceId` is shared by +many spans, may be absent from logs, and does not exist on metrics. Sealing a +fixed UTC-day range into an immutable generation makes each generation +independently reproducible and avoids scanning all generations to dedup. Late +telemetry creates a new generation; the active pointer selects it; the old +generation stays on disk but is excluded from listings and queries until GC. + +**Three distinct units (logical chunk / physical shard / row group).** A logical +chunk is a provisioning target (`targetChunkBytes`, not a hard limit); a physical +shard is one Parquet file bounded by `maxShardRows`/`maxShardBytes` covering one +UTC hour, recursively bisected at the `_part_offset` boundary if it exceeds the +byte bound; a Parquet row group is the compression/decode unit (`rowGroupRows`). +Keeping these separate lets operators tune for their row width, cardinality, and +storage without conflating provisioning with physical layout. + +**A single reconciliation decision function.** `decideReconciliation` is the sole +pure transition table for create and GC recovery. There is no second `if phase` +implementation anywhere — this invariant is enforced by review and is what makes +crash recovery auditable. A phase label is never proof: the decision and the +terminal checks re-read reality from disk. + +**Defense-in-depth config loading.** A calibration config is loaded with `lstat` +→ size cap → `open(O_NOFOLLOW)` → `fstat` → **fd-identity check** → bounded +read, and the SHA-256 is computed over the exact bytes from the one fd. The +config's structured identity (`{ formatVersion, configName, sha256 }`) is bound +into the generation manifest so a generation records exactly which config +produced it and deployment drift is visible. + +## Dependency on PR #129 + +This branch is **dependent on PR #129** (`codex/chdb-checkpoints`, native chDB +checkpoint create/restore). Archives restore a checkpoint into scratch and +export from it; without PR #129's validated, restorable checkpoints there is no +safe source. The checkpoint manifest fingerprint (`checkpointId:createdAt:backupBytes`) +is recorded in every generation manifest, binding each archive to its exact +source. **PR #129 must land first** (or be co-dependent); this PR does not +duplicate checkpoint logic. + +## Resource and adoption implications + +- **Disk:** the archive volume grows with retained historical ranges. The volume + must be separate from the live data directory. `minFreeSpaceReserve` enforces + headroom at operation time; `archive gc` bounds growth by reclaiming + superseded generations. +- **Memory/CPU during export:** export restores a checkpoint into scratch, adding + temporary scratch-restore capacity. Because checkpoint validation and archive + export share **one** sacrificial chDB, export does not add a second concurrent + full-memory OLAP copy; rotation adds duration and disk I/O to that working set, + not another `f(4)` memory term. Calibration measures the real peak RSS per + candidate via `/usr/bin/time` and selects within a declared budget. +- **Concurrency:** export, checkpoint create/restore/reset, and GC all take the + maintenance lock, so they serialize. This is intentional and safe. +- **Operators** adopt by: taking a checkpoint, (optionally) calibrating, running + `archive create` per signal/day, then querying the active paths in DuckDB. No + second database runs at rest. + +## Happy path + +1. Ingest telemetry into the running Maple store. +2. `maple checkpoint` creates a validated checkpoint. +3. (Optional) `maple archive calibrate --write-config cfg.json` tunes for + the deployment; then pass `--config cfg.json` to `create`. +4. `maple archive create 2026-06-01 traces` (and the other five signals) seals + each day/signal into a validated generation. +5. `maple archive list --output paths --signal traces` returns the active + Parquet shard paths (superseded generations excluded). +6. DuckDB answers historical queries with exact source counts: + `read_parquet(, union_by_name=true)`. + +Every archived day's row count is validated against the source +(`sourceRowCount == archivedRowCount == Σ shard.rowCount`), and `archive list` +re-verifies each shard's SHA-256 and byte size against the manifest before +returning it. + +## Major failure outcomes + +Every archive failure leaves the **live store untouched** — export reads only +from restored scratch. The categories: + +- **No generation written:** unavailable or incompatible checkpoint, free-space + preflight failure, partial shard (exceeds bounds), or validation mismatch.

From 83b395b2edcd2078872f118e413eeee2be0d8163 Mon Sep 17 00:00:00 2001 From: remote service administrator Date: Thu, 2 Jul 2026 08:36:02 -0400 Subject: [PATCH 60/78] fix(archive): strict manifests, session calibration, semantic config, volume binding Architectural repair for the R9/R10 fresh-review NO-GO (D-024), in one commit atop 5d891e83. Manifest v3 strictness (finding 1). parseArchiveGenerationManifest is now exact-key (assertExactOwnKeys over MANIFEST_KEYS) and rejects unknown top-level fields. The tuning block is parsed by parseTuningRecord, which enforces positive integers and the same cross-field invariants as the writer. Omitting tuningConfig now fails closed instead of normalizing to null; zero/invalid tuning is rejected. tuningConfig accepts the two known config format identities (legacy v1 + verified v2) since the manifest stores an opaque hash-bound identity; only the loader refuses v1 for new writes. Calibration intent-retention wedge (finding 2). reconcileCalibration catches a resolveCheckpoint failure and, when the record is a provably inert intent (phase intent, pinPath null, every exact derived checkpoint/pin/scratch/ sample resource absent via classifyArchivePathSync), retires the record without resolving the retired source. Any ambiguity preserves the record. Calibration/config acceptance contract (finding 3). Calibration is now a parent-owned session: the parent resolves ONE checkpoint, acquires ONE pin, and threads the exact checkpointId+fingerprint to every child. Children (assertCalibrationSession) refuse current/previous, bind to the parent's operation/checkpoint/fingerprint, verify the parent pin is live, and clean only their own sample (cleanupCalibrationSample); the parent owns full reconcileCalibration in a finally. Held-out results, worstCase, comparisons, tolerances, and a heldOutAttempts log are retained in the recommendation and written to the config. Tolerances are one canonical exported constant (HELD_OUT_TOLERANCES) and the loader recomputes the comparison, rejecting a forged withinTolerance. The two non-candidate knobs are DERIVED (deriveTargetChunkBytes = max(4*maxShardBytes, reserve+maxShardBytes); minFreeSpaceReserve = budget.freeSpaceReserve) and the derivation formula + recomputed effective block are re-verified by the loader. Config format bumped to 2; confidence must be high to load. A new calibrate-session command (open/close) makes the parent session lifecycle explicit so a single child or SIGKILL probe can run against an open session and an operator can retire a wedged one. Environment + volume identity at create (findings 5,7). archive create --config enforces the recorded mapleVersion/chdbVersion/schemaFingerprint/ executionUser/platform/arch/cpuModel/cpuCount/totalMemoryBytes and the archive-volume fsid/type + canonical path against the live host (assertCalibrationEnvironment), and re-checks the volume identity immediately before publication (beforePublicationVolumeRecheck seam). archiveVolumeIdentity no longer climbs ancestors: it requires an existing real non-symlink canonical directory. R9 documentation corrections. Recovery, quarantine, catalog, calibration cleanup, operation paths, free-space, list output, volume, and capacity claims are corrected to match actual behavior; both docs pass oxfmt.

Findings 1, 2, and 4 plus the core of finding 3. Canonical tolerances + triggers (finding 1). HELD_OUT_TOLERANCES and RECALIBRATION_TRIGGERS now live once in config.ts (CALIBRATION_HELD_OUT_TOLERANCES / CALIBRATION_RECALIBRATION_TRIGGERS) and the loader requires the document's heldOut.tolerances and recalibrationTriggers to exactly match them (exactJson), so a document can no longer redefine its own comparison policy to pass a 1000x wall regression. Tolerances tightened so every metric is < 1.0. Strict parent-pin identity (finding 2). assertCheckpointPinIdentity is one shared strict validator (exact keys, formatVersion, pinId, checkpointId, purpose regex, parseable createdAt) used by both releaseCheckpointPin and assertCalibrationSession. assertCalibrationSession now parses the derived pin and requires exact id/checkpoint/purpose, so a substituted same-path regular file (e.g. '{}') is no longer accepted as the live parent pin. Larger, persisted, auditable held-out scope (finding 3). The held-out window is now STRICTLY LARGER than training and disjoint: training covers ordered rows [0, sampleRows); held-out covers [sampleRows, sampleRows + 2*sampleRows). Every training and held-out result carries a persisted sample scope ({checkpointId, checkpointManifestFingerprint, rangeDate, role, startRow, requestedRows, rowCount}) emitted by the child (the authoritative source) and attached by the parent. The config document records a samplePolicy (trainingRows, heldOutMultiplier=2, heldOutRows, training/heldOut windows), and the loader re-verifies: all scopes bind to ONE checkpoint/range; training is role training, startRow 0, requestedRows=budget.sampleRows; held-out is role held-out, startRow=sampleRows, requestedRows=heldOutRows; rowCount matches metrics.rowCount; failed results record no scope. Representative-data confidence now matches all four candidate fields (isSameCalibrationCandidate), not just writerThreads. Metric-coherence validation rejects forged compressionRatio/throughput; positive freeSpaceReserve enforced; recalibration triggers exact. R9 documentation (finding 4). Both docs corrected to config v2, 306 tests, the canonical <1.0 tolerances, null-selected throws (no config written), the new samplePolicy/scope fields, and the larger disjoint held-out window. The stale 'separate validation report' and 'low-confidence config may be written' claims are removed. Native calibrate probe asserts the larger persisted held-out scope and samplePolicy for every result. Unit tests add five hostile scope-forgery cases (forged checkpoint, role, non-disjoint startRow, rowCount mismatch, samplePolicy multiplier) and a held-out-larger-and-disjoint property. 306/306 unit; typecheck/lint/format/diff-check clean. --- apps/cli/src/commands/archive.ts | 68 ++++- apps/cli/src/server/archives/calibrate.ts | 92 ++++-- .../server/archives/calibration-recovery.ts | 13 +- apps/cli/src/server/archives/config.ts | 263 ++++++++++++++++-- apps/cli/src/server/checkpoints.ts | 37 ++- apps/cli/test/archive-calibrate.test.ts | 164 +++++++++-- apps/cli/test/archive-config.test.ts | 66 ++++- .../test/native-archive-calibrate-probe.sh | 19 ++ docs/local-telemetry-archives.md | 75 +++-- docs/pr-local-telemetry-archives.md | 16 +- 10 files changed, 699 insertions(+), 114 deletions(-) diff --git a/apps/cli/src/commands/archive.ts b/apps/cli/src/commands/archive.ts index f1cb4fd49..beb751b0c 100644 --- a/apps/cli/src/commands/archive.ts +++ b/apps/cli/src/commands/archive.ts @@ -31,6 +31,8 @@ import { writeCalibrationConfig, type CalibrationRecommendation, HELD_OUT_TOLERANCES, + isSameCalibrationCandidate, + heldOutSampleRows, comparePredictedObserved, } from "../server/archives/calibrate" import { @@ -656,6 +658,16 @@ interface ChildMetrics { readonly peakRssBytes: number readonly exportWallMs: number readonly rowCount: number + /** The exact ordered-row sample scope this child exported (tamper-evidence). */ + readonly sample: { + readonly checkpointId: string + readonly checkpointManifestFingerprint: string + readonly rangeDate: string + readonly role: "training" | "held-out" + readonly startRow: number + readonly requestedRows: number + readonly rowCount: number + } } /** `/usr/bin/time` argv: `-lp` on macOS/BSD, `-v` on GNU/Linux. */ @@ -696,6 +708,7 @@ const runCandidateChild = ( budget: CalibrationBudget, operationId: string, startRow: number, + sampleRows: number, matrixStart: number, ): Promise => { return new Promise((resolvePromise) => { @@ -719,7 +732,7 @@ const runCandidateChild = ( "--start-row", String(startRow), "--sample-rows", - String(budget.sampleRows), + String(sampleRows), "--max-temp-disk", String(budget.maxTempDiskBytes), "--free-space-reserve", @@ -850,7 +863,33 @@ const runCandidateChild = ( wallMs: raw.exportWallMs, rowCount: raw.rowCount, } - resolvePromise({ candidate, signal, metrics, ok: true }) + // Bind the child's authoritative sample scope.

The held-out sample is now strictly LARGER than training and disjoint: training covers ordered rows [0, sampleRows); held-out covers [sampleRows, sampleRows + 2*sampleRows) (heldOutSampleRows = HELD_OUT_SAMPLE_MULTIPLIER * sampleRows). Every training and held-out result carries a persisted sample scope ({checkpointId, checkpointManifestFingerprint, rangeDate, role, startRow, requestedRows, rowCount}) emitted by the child and attached by the parent; the config records a samplePolicy and the loader proves every scope binds to ONE checkpoint/range and that the two windows are disjoint and correctly sized. Hybrid predicted-vs-observed comparison (per the calibrator contract): because a 2x-larger held-out naturally takes ~2x wall time and bytes, wallMs and physicalBytes predictions are rescaled by heldOut.logicalBytes / training.logicalBytes before the two-sided check; throughput and compressionRatio (size-invariant rates) compare directly; peak RSS and peak temp disk compare as absolute peaks (NOT scaled by row count — they are process peaks, not per-row costs). The raw values, scale ratio, training/held-out logical bytes, adjusted predictions, and comparison results are all persisted; the loader recomputes the ratio and every comparison from the recorded evidence using the fixed canonical tolerances only (no run-specific widening). comparePredictedObserved gains an optional sizeScaling param mirrored by the loader's expectedComparisons. Native calibrate probe asserts the larger persisted held-out scope and samplePolicy for every result (training=10 held-out=20, disjoint, single source) and the loop closes through the hybrid comparison. Unit tests add hostile forged-scale-ratio and forged-scope cases plus a held-out-larger-and-disjoint property. 306/306 unit; typecheck/lint/format/diff-check clean. --- apps/cli/src/commands/archive.ts | 24 +++++- apps/cli/src/server/archives/calibrate.ts | 43 ++++++++--- apps/cli/src/server/archives/config.ts | 89 +++++++++++++++++++++-- apps/cli/test/archive-calibrate.test.ts | 18 ++++- apps/cli/test/archive-config.test.ts | 24 +++++- 5 files changed, 174 insertions(+), 24 deletions(-) diff --git a/apps/cli/src/commands/archive.ts b/apps/cli/src/commands/archive.ts index beb751b0c..7bec025ad 100644 --- a/apps/cli/src/commands/archive.ts +++ b/apps/cli/src/commands/archive.ts @@ -1086,13 +1086,28 @@ const runBoundCalibrationMatrix = async ( budget, requiredSignals, )[0]!.worstCase - const comparison = comparePredictedObserved(cand.worstCase, heldWorst, HELD_OUT_TOLERANCES) + // The held-out sample is larger than training, so absolute + // size-proportional metrics (wallMs, physicalBytes) are rescaled + // by the logical-bytes ratio before the two-sided check; throughput + // and compressionRatio are size-invariant rates compared directly; + // peak RSS and peak temp disk are absolute peaks.

From a1328a0697ed74e56084feed8940e2ab5bbe0eed Mon Sep 17 00:00:00 2001 From: remote service administrator Date: Thu, 2 Jul 2026 20:00:11 -0400 Subject: [PATCH 64/78] fix(archive): per-signal like-for-like held-out hybrid comparison MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Closes the final D-026 contract: the held-out comparison is now PER-SIGNAL and like-for-like, replacing the cross-signal aggregate ratio that could mask a single-signal regression. Each signal's held-out result is paired with the same candidate's TRAINING result for that signal (compareHeldOutPerSignal). wallMs/physicalBytes are scaled by THAT signal's own heldOut.logicalBytes/training.logicalBytes ratio; throughput and compressionRatio are compared directly (size-invariant rates); peak RSS and peak temp disk are compared as absolute peaks. The attempt passes only when ALL SIX signals pass; cross-signal aggregate extrema (worstCase) are recorded only as a descriptive summary and never decide acceptance. Data model (config format stays v2): heldOut and each heldOutAttempts entry carry signalComparisons [{signal, scaleRatio, comparisons, passed}] in canonical six-signal order — no duplicated raw metrics (the loader re-derives pairs by exact candidate + signal identity). A complete attempt has six entries even when it fails; an incomplete/over-budget/short-window attempt has signalComparisons: [], worstCase: null, passed: false. Training and held-out logicalBytes must both be strictly positive (an undefined ratio makes the attempt incomplete, never silently ratio 1). The loader recomputes every per-signal ratio, adjusted prediction, relative delta, and pass flag via expectedSignalComparisons and requires exactJson agreement. The runner-level compareHeldOutPerSignal is pure and unit-tested with the reviewer's exact cross-signal counterexample (signal A regresses 1.0 under per-signal but aggregate reports delta 0). Hostile cases updated for the per-signal shape (forged comparison, forged scaleRatio, forged canonical tolerances with recomputed per-signal comparisons). calibration-validation-compare.ts (probe reference) now imports canonical HELD_OUT_TOLERANCES and applies the per-signal logical-byte ratio. Native probe asserts six signalComparisons in canonical order, each with its own ratio. R9 hybrid section documents signalComparisons, per-signal scaling, and the complete-vs-incomplete shape. 309/309 unit; typecheck/lint/format/diff-check clean. --- apps/cli/src/commands/archive.ts | 65 +++--- apps/cli/src/server/archives/calibrate.ts | 88 ++++++++- apps/cli/src/server/archives/config.ts | 185 +++++++++--------- apps/cli/test/archive-calibrate.test.ts | 109 ++++++++--- apps/cli/test/archive-config.test.ts | 79 ++++---- .../test/native-archive-calibrate-probe.sh | 13 ++ .../probes/calibration-validation-compare.ts | 28 ++- docs/local-telemetry-archives.md | 40 ++-- 8 files changed, 388 insertions(+), 219 deletions(-) diff --git a/apps/cli/src/commands/archive.ts b/apps/cli/src/commands/archive.ts index dc003eacb..b4c4b3a7b 100644 --- a/apps/cli/src/commands/archive.ts +++ b/apps/cli/src/commands/archive.ts @@ -33,7 +33,7 @@ import { HELD_OUT_TOLERANCES, isSameCalibrationCandidate, heldOutSampleRows, - comparePredictedObserved, + compareHeldOutPerSignal, } from "../server/archives/calibrate" import { preflightCalibrationFreeSpace, @@ -1099,7 +1099,9 @@ const runBoundCalibrationMatrix = async ( ) heldOutResults.push(result) } - // Require complete six-signal held-out evidence (not an empty array). + // Require complete six-signal held-out evidence: every result within + // ceilings AND observing exactly heldOutSampleRows rows (a larger + // request is not a larger observed sample). const heldOutComplete = heldOutResults.length === requiredSignals.length && heldOutResults.every( @@ -1113,56 +1115,57 @@ const runBoundCalibrationMatrix = async ( budget, requiredSignals, )[0]!.worstCase - // The held-out sample is larger than training, so absolute - // size-proportional metrics (wallMs, physicalBytes) are rescaled - // by the logical-bytes ratio before the two-sided check; throughput - // and compressionRatio are size-invariant rates compared directly; - // peak RSS and peak temp disk are absolute peaks.

This document is the long-form PR narrative for the -> `local-telemetry-archives` feature branch. It is written fresh against the -> implementation at the branch head; it supersedes and does not reuse any prior -> draft PR materials. It is intended to become the body of the dependent pull -> request once a push is authorized. - -## Summary - -This PR adds **local telemetry archives**: long-term, portable Parquet storage -exported from immutable Maple checkpoints, queryable independently with DuckDB. -It lets an operator retain telemetry history far beyond the hot store's 30/90-day -TTL **without** reloading history into the live chDB store and **without** -running a second always-on database. An archived day is a set of immutable -Parquet files, sealed once, that any DuckDB can read. - -## What this is - -- Export of the **six raw telemetry tables** (`logs`, `traces`, `metrics_sum`, - `metrics_gauge`, `metrics_histogram`, `metrics_exponential_histogram`) from a - validated checkpoint into Parquet, sealed by fixed UTC day and signal. -- A generation model where each sealed day is an immutable **generation**; late - telemetry creates a newer generation that supersedes, selected atomically by an - `active.json` pointer. -- A **calibration** workflow that measures export behavior on the deployment's - hardware and emits a versioned, SHA-256-bound tuning config. -- Crash-safe create and GC: their mutations are journaled, calibration uses - separate recovery records, and a single pure decision function owns - create/GC recovery branch logic. -- A conservative **garbage collector** that reclaims superseded generations by - tombstone-rename with terminal-invariant proofs. -- Full operator/architecture documentation (`docs/local-telemetry-archives.md`). - -## Why each major choice was made - -**Checkpoint-restored scratch, not a live copy.** A raw copy of the live data -directory is unsafe: it captures an inconsistent on-disk state, may include -half-written merges, and races concurrent ingest. The only proven safe source is -a native chDB checkpoint restored into sacrificial scratch. Export restores one -checkpoint into a private scratch chDB (the same scoped instance checkpoint -validation uses), exports from it, then removes the scratch. The live store is -never opened for export. This is also why export holds the maintenance lock: it -shares the one sacrificial chDB with checkpoint operations and must serialize. - -**Generations supersede; we do not deduplicate by `TraceId`.** There is no -universal deduplication key across the six raw tables — `TraceId` is shared by -many spans, may be absent from logs, and does not exist on metrics. Sealing a -fixed UTC-day range into an immutable generation makes each generation -independently reproducible and avoids scanning all generations to dedup. Late -telemetry creates a new generation; the active pointer selects it; the old -generation stays on disk but is excluded from listings and queries until GC. - -**Three distinct units (logical chunk / physical shard / row group).** A logical -chunk is a provisioning target (`targetChunkBytes`, not a hard limit); a physical -shard is one Parquet file bounded by `maxShardRows`/`maxShardBytes` covering one -UTC hour, recursively bisected at the `_part_offset` boundary if it exceeds the -byte bound; a Parquet row group is the compression/decode unit (`rowGroupRows`). -Keeping these separate lets operators tune for their row width, cardinality, and -storage without conflating provisioning with physical layout. - -**A single reconciliation decision function.** `decideReconciliation` is the sole -pure transition table for create and GC recovery. There is no second `if phase` -implementation anywhere — this invariant is enforced by review and is what makes -crash recovery auditable. A phase label is never proof: the decision and the -terminal checks re-read reality from disk. - -**Defense-in-depth config loading.** A calibration config is loaded with `lstat` -→ size cap → `open(O_NOFOLLOW)` → `fstat` → **fd-identity check** → bounded -read, and the SHA-256 is computed over the exact bytes from the one fd. The -config's structured identity (`{ formatVersion, configName, sha256 }`) is bound -into the generation manifest so a generation records exactly which config -produced it and deployment drift is visible. - -## Dependency on PR #129 - -This branch is **dependent on PR #129** (`codex/chdb-checkpoints`, native chDB -checkpoint create/restore). Archives restore a checkpoint into scratch and -export from it; without PR #129's validated, restorable checkpoints there is no -safe source. The checkpoint manifest fingerprint (`checkpointId:createdAt:backupBytes`) -is recorded in every generation manifest, binding each archive to its exact -source. **PR #129 must land first** (or be co-dependent); this PR does not -duplicate checkpoint logic. - -## Resource and adoption implications - -- **Disk:** the archive volume grows with retained historical ranges. The volume - must be separate from the live data directory. Create requires - `minFreeSpaceReserve + targetChunkBytes`; calibration children require - `freeSpaceReserve + 4 * maxShardBytes`. `archive gc` bounds growth by - reclaiming superseded generations. -- **Memory/CPU during export:** export restores a checkpoint into scratch, adding - temporary scratch-restore capacity. Because checkpoint validation and archive - export share **one** sacrificial chDB, export does not add a second concurrent - full-memory OLAP copy; rotation adds duration and disk I/O to that working set, - not another `f(4)` memory term. Calibration measures the real peak RSS per - candidate via `/usr/bin/time` and selects within a declared budget. -- **Concurrency:** export, checkpoint create/restore/reset, and GC all take the - maintenance lock, so they serialize. This is intentional and safe. -- **Operators** adopt by: taking a checkpoint, (optionally) calibrating, running - `archive create` per signal/day, then querying the active paths in DuckDB.

(Optional) `maple archive calibrate --write-config cfg.json` tunes for - the deployment; then pass `--config cfg.json` to `create`. -4. `maple archive create 2026-06-01 traces` (and the other five signals) seals - each day/signal into a validated generation. -5. `maple archive list --output paths --signal traces` returns the active - Parquet shard paths (superseded generations excluded). -6. DuckDB answers historical queries with exact source counts: - `read_parquet(, union_by_name=true)`. - -Every archived day's row count is validated against the source -(`sourceRowCount == archivedRowCount == Σ shard.rowCount`), and `archive list` -re-verifies each shard's SHA-256 and byte size against the manifest before -returning it. - -## Major failure outcomes - -Every archive failure leaves the **live store untouched** — export reads only -from restored scratch. The categories: - -- **No generation written:** unavailable or incompatible checkpoint, free-space - preflight failure, a single matching row exceeding `maxShardBytes`, or a - validation mismatch. No active pointer changes. -- **Recoverable or retained debris:** the next `create` or - `archive reconcile` releases exact create scratch/pin ownership and moves - pre-publication building output into retained quarantine.
