From d9c319984511640b6767f2c3c1d93c4f1e24ea2a Mon Sep 17 00:00:00 2001 From: Max Ghenis Date: Wed, 2 Sep 2026 11:00:05 -0400 Subject: [PATCH 001/212] Add one shared chronicle-first env helper Chronicle's operational stores migrate by dual-run (chronicle#143, mechanism 3). Every env read was ledger-first with no chronicle-named alternative, and each of the three modules that read configuration had grown its own helper. Add chronicle/env.py: env_value/env_flag expand a name into CHRONICLE_, LEDGER_, POLICYENGINE_LEDGER_ and return the first set value, warning once per process with ChronicleEnvDeprecationWarning when a ledger-era name supplied it. Names outside those three prefixes, such as POLICYENGINE_SUPABASE_URL, are read literally so the helper renames the ledger-era surface only. The warning subclasses FutureWarning, not DeprecationWarning, so operators running the CLI actually see it. The Supabase schema name stays "ledger"; only the env var that overrides it moves to CHRONICLE_SCHEMA. Renaming the schema is a later slice.

Defaults are unchanged at ledger-raw and ledger-derived; only the follow-up cutover PR flips them. Plumbed through fetch-artifact, publish-raw, publish-derived and bootstrap-r2, whose --r2-bucket/--raw-bucket/--derived-bucket now default to the resolver. Because the bucket can now vary, two manifest write paths could restate recorded storage.r2 blocks. Archived witness records pin raw R2 URLs by hash, so both now preserve history: publish-raw reports recorded_r2_bucket_is_preserved_history instead of uploading, and fetch-artifact keeps an already-recorded r2 block rather than overwriting it with a different bucket. The consumer-fact boundary guard matched the literal strings ledger-derived: and r2://ledger-derived/, so a renamed bucket would have made it silently stop firing. It now matches on shape (bucket ends in -derived, or key starts with derived/) and parses the r2:// URI, which also closes the uri-only hole where a fact carrying no bucket or key slipped past. Database artifact: new suite outputs write chronicle.db. infer_build_id reads chronicle.db then ledger.db (both branches were byte-identical, so the existing fallback was a no-op), and _derived_artifact_kind classifies both names (its set literal held one element twice). The sidecar resource list moves with the write site because _resource_descriptor stats every listed path. Fix db/cli.py, which imported the private env reader that the shared helper replaced. That ImportError broke every db CLI subcommand, including the three the CI job runs, while pytest stayed green.

It then exercises the real call sites -- source-package artifact cache and fetch flag, the db CLI's --pe-us-root default, the Supabase schema override, and R2 bucket resolution -- so a helper regression cannot pass by only testing the helper. An autouse fixture strips every rename-window variable from the ambient environment, so the file is hermetic under any shell. The artifacts tests cover the chronicle.db write and ledger.db read fallback, both database names classifying as sqlite_database, publish-derived following the configured bucket, and the two manifest-preservation paths: publish-raw refusing to restate a recorded bucket and fetch-artifact keeping the recorded r2 block while still uploading the backfill copy.

Replaced with an "Environment Variable Rename Window" section that gives the actual lookup order, the once-per-process warning, and a table of all seven variables. Two behaviors get stated outright because both invert a naive fallback: the CHRONICLE_ name wins even when it reads false, so a migrated operator can turn a flag off without hunting down a stale legacy export; and an empty value counts as unset. The section also records what is deliberately NOT aliased -- POLICYENGINE_SUPABASE_* and POLICYENGINE_TARGETS_SCHEMA carry no ledger prefix and are read literally -- and that CHRONICLE_SCHEMA renames the override variable, not the schema value, which moves in a later slice. Added a "Bucket Cutover" section covering the six steps: create the buckets on the account wrangler.toml pins, enumerate, backfill-copy, verify, flip the defaults in a follow-up, and leave the ledger-era buckets read-only forever. The enumeration and verification are given as commands rather than prose. Every raw key ends {sha256}/{filename}, so the key is its own checksum witness and verification needs no manifest lookup. Counted rather than assumed: 186 distinct ledger-raw objects across 154 tracked manifest files, and the doc says to recount rather than trust that number, since source packages land continuously. The derived bucket needs no backfill -- derived artifacts are reproducible and already keyed by {build_id}, so a rebuild republishes them wherever configured. README and the harness doc follow: bucket references become archive roles with the default named, ledger.db becomes chronicle.db with the legacy name noted as still readable, and bootstrap-r2's example drops the hardcoded bucket flags now that they default to the resolver. Left alone: LEDGER_EXPLORER_DATA_DIRS in the README. It configures the explorer app, which is not in this repository, so renaming it here would document a name no shipped code honors -- the same defect this commit fixes in the other direction.

When a publisher re-publishes under the same URL and vintage — the IRS did exactly this to the 2022 IRA tables today (PolicyEngine/chronicle#225) — the manifest ended up describing the new bytes while pointing at the old object's key and URI. Verified against this branch's parent: a second fetch of different bytes leaves sha256=109dcf49… in an entry whose storage.r2 key is addressed by c63744a4…, both when the fetch only registers the bytes and when the bucket default has moved. Identity now decides, not the bucket: - the recorded key's last two segments (sha256, filename) are compared with the fetched bytes. Identical: the recorded block is preserved exactly, whichever bucket is configured now. Different: SourceArtifactRevisionError, raised before the cached artifact or its manifest entry is touched, naming recorded and fetched sha256/size_bytes and the ADR rule that the same vintage with new bytes is a new release revision. - --record-revision opts in: the fetched bytes get their own content-addressed key under the configured bucket, never the old key, and the superseded block moves to storage.previous_r2 with its sha256, size_bytes and fetched_at so the earlier bytes stay addressable. - publish-raw applies the same check before treating a recorded block as history, so a local file the recorded object does not hold is refused rather than uploaded. storage.previous_r2 is a sibling of storage.r2: every reader (inventory-artifacts, publish-raw, source_package._artifact_content and the suite's raw-R2-link acceptance check) reads storage.r2 alone, and publish-raw already spreads the existing storage block when it rewrites, so a revision survives publication untouched.

The default now resolves through the shared helper -- one home for the CHRONICLE_SCHEMA -> POLICYENGINE_LEDGER_SCHEMA -> LEDGER_SCHEMA -> "ledger" ladder -- whenever no explicit --schema is supplied. Defaults are unchanged. Resolution is a function rather than a module constant, so db.supabase_client no longer binds the schema while being imported. That import happens at collection, before any fixture, which is why the namespace test needed a reload dance to assert the defaults; it now just calls the resolver. A pytest_configure hook clears the rename window before collection too, so no module can read (or warn from) an operator's shell on the way in. Six tests fail against the previous code: the loader and its CLI ignore the variable, and the namespace assertions see the collection-time constant.

Seven tracked packages keep a manifest_*_source_package.yaml instead, and three publisher directories keep two of them, so the IRA revision workflow the docs cite would have written a third manifest beside the real ones and never seen the recorded block. A --manifest filename now selects it; the name has to stay inside the package. - Revision protection vanished when the entry had no storage.r2 -- a fetch that only registered bytes, or one whose upload failed, which is the state #225 landed in. A manifest entry identifies its bytes by its declared sha256 whether or not it has been published, and a fetch of different bytes over either identity is refused unless --record-revision opts in. - Recorded R2 validation read the key or the uri, whichever came first. A block whose key and uri named different objects was preserved verbatim, so the entry kept publishing a URI for bytes it no longer described. Every supplied locator field is now cross-checked against every other and against the content-addressed key shape; a contradiction is an error at fetch time and a refusal at publish time, never a silent preserve. - A manifest that parsed as anything but a mapping was treated as absent, so the fetch would replace it with a single entry. It is now refused before the publisher is read at all, and inventory-artifacts and publish-raw report it rather than crashing on it. The refusals share a SourceArtifactManifestError base, so the CLI reports all of them as an exit-1 message with nothing written.

Every sha256, size, filename, and vintage is read verbatim from Microcosm's reviewed pins; the script authors only the Chronicle identity and the publisher terms. `emit` writes hash-only kind: microdata_release manifests for licensed and restricted releases: 14 distinct DWP FRS 2023-24 tabs (19 references across five Microcosm stages resolve to 14 distinct files) and the HMRC SPI Public Use Tape 2022-23. No bytes are fetched or stored and no R2 key is recorded. BE-SILC 2023 is reported as a blocker rather than registered: Microcosm pins it with no sha256, size, or per-file filename, and no hash is invented. `plan` prints the exact fetch-artifact commands for public releases, copying publisher URLs verbatim and printing TODO where Microcosm records none. Also updates the two artifact-count assertions for the new hash_only_count and hash_only_refused_count report keys.

Also pins the committed FRS and SPI registrations as identity-only: no storage block, no R2 key, no bytes beside the manifest. Reorders the fetch refusals so overwriting a hash-only registration reports the byte-boundary violation rather than prompting for --licence.

Ghenis Date: Wed, 2 Sep 2026 11:42:51 -0400 Subject: [PATCH 093/212] Document hash-only registrations and the BE-SILC blocker Adds the microdata-release example to the storage doc's Object Key Conventions (public releases keep the ordinary content-addressed key; licensed and restricted ones have no key at all), a Hash-Only Registrations section to the harness doc, a register-artifact entry to the README artifact command block, and a data-sources note recording why BE-SILC 2023 cannot be registered yet. The governance, architecture, AGENTS, and non-goal amendments are left to the ADR branch (PR #222), which already makes them.

It now replaces only the entry for its own filename. - register_hash_only_artifact raised on the first filename match with a different checksum, so re-registering a current pin failed once a reissue existed and `emit` stopped being re-runnable. Now two passes: an exact (filename, sha256) match is replaced wherever it sits. - publish-raw returned before validating a hash-only entry, so --skip-hash-only reported bytes on disk or a recorded R2 key as valid, disagreeing with inventory-artifacts about the same tree. The entry is now always validated; the flag turns off the refusal, not the contract check. - Nothing could register a public microdata release as kind: microdata_release, though the ADR puts redistributable public-use files in scope. fetch-artifact gains --kind, and a microdata-release manifest keeps the list shape so several files can share one vintage. - Every command `plan` printed used --source-url, which fetch-artifact does not accept; all nine died at argparse.

None of that was in the registration vocabulary: - manifest_kind() no longer defaults a manifest with content to publisher_table. Manifests that predate the rule are frozen byte for byte in chronicle/grandfathered_manifests.py; any other kindless manifest is a ManifestKindError. - chronicle/licences.py is the allowlist of redistributable terms (a U.S. Government work, OGL v3, CC0, CC BY 4.0), each with its evidence URL, and the validator for a licence_evidence block binding one artifact to one term. - hash_source is the closed set chronicle_fetch / consumer_attested / consumer_pin, each with its attester fields; register_hash_only_artifact requires one and refuses a consumer_pin with a verified_at. - Filenames are bare names compared case-folded (bare_filename, filename_key), 2023 and '2023' are one vintage key (resolve_vintage_key), and validate_manifest_files reports duplicate keys, non-canonical names and filename collisions across a whole manifest. - register_hash_only_artifact refuses to reclassify an entry that is public or records an R2 object, resolves the vintage key the manifest already uses, and validates the manifest before touching it.

Each of those let bytes past the hash-only boundary or lost a recorded identity. Now, before the publisher is read: the filename is a bare name (inferred from the URL without I/O when --filename is omitted), every alias of a hash-only registration is refused, a --kind that conflicts with the manifest is refused, a kindless manifest with content is refused, and the whole manifest is validated with the same codes inventory reports. The vintage entry is selected by key spelling and bare filename, so PR #226's recorded identity guard covers list-shaped release vintages, and _upsert_manifest replaces that entry in place, carries forward the fields a fetch does not own, never turns a publisher-table mapping into a list, and always writes kind. A public microdata release is archived only with --expected-sha256 and licence evidence bound to it: the fetched bytes are checked against the pin before anything is written or uploaded, --record-revision does not override that, and the bytes are staged outside the package tree and uploaded from there. The entry records hash_source chronicle_fetch, attested_by chronicle and the fetch date. publish-raw and inventory-artifacts report manifest-level defects, skip a manifest they cannot classify, and read release bytes from the staging directory only. The CLI gains the matching flags and prints refusals as errors instead of tracebacks.

Each registration is now a consumer_pin: attested_by PolicyEngine/microcosm, pinned_from the consumer manifest's repository, path and the last commit that changed it, no verified_at. The 15 committed FRS and SPI rows are re-emitted that way; their SHA-256 and size pins are byte-identical (verified against the microcosm blobs at commits 2fb2e2f8 and de7451bd). plan discarded publisher and vintage and printed the reviewed checksum as a comment. Every command now carries --publisher, --vintage, --filename when pinned, --expected-sha256 and --expected-size-bytes when Microcosm's pin is of the publisher bytes, the allowlisted licence US-Government-Work and its evidence issuer and scope. Anything unknown -- a URL, a publisher-bytes checksum, an evidence URL -- prints a TODO the CLI refuses, never a guess.

The committed pins are a golden mapping. Regression tests cover every gate finding: filename aliases, the byte reader, reclassification of an archived identity, kind conflicts and strict pre-fetch validation, inference before the read, in-place list updates under the recorded-identity guard, quoted year keys, the expected identity, and the explicit-kind rule with its frozen list and the no-tracked-microdata-bytes guard.

Rebasing this branch over it left three seams, each reproduced failing-first on the rebased tree: - RawArtifactPublishEntry.to_dict listed "skipped" twice (ruff F601). The hash-only skip now shares #226's skipped/uploaded vocabulary behind HASH_ONLY_SKIP_PREFIX, so publish-raw counts both skipped_count and hash_only_refused_count without conflating them. - #226's explicit-null files: cases were refused by the explicit-kind rule: a kindless manifest holding source_id and a bare files: line has no entry that could be read as a publisher table. has_file_entries() says so, and manifest_kind treats an entry-less manifest like an absent one: the command writing its first entry declares the kind. A declared kind stays fixed (register-artifact and fetch-artifact --kind still refuse to reclassify one), and register-artifact records into a fresh mapping on an explicit null just as fetch does. - test_emit_needs_a_commit_it_can_read_or_be_told read a Chronicle commit once the fixture was committed here; it now copies the fixture outside any repository and into one where the manifests are untracked, and refuses in both. _upsert_manifest's repeated revision guard now calls the same _assert_recorded_identity_holds_these_bytes as the preflight, so #226's rename rule (identical bytes under another name, --record-revision does not apply) holds at the write as well; a direct call is pinned by test_the_manifest_write_refuses_a_same_bytes_rename_by_itself.

The hash-only guard read only that manifest, so a release registered licensed in manifest.yaml could be fetched, published through a sibling manifest_.yaml, parsed by a source package that reads through the sibling, or reclassified by register-artifact, all under the very name the registration says must never hold bytes. Reproduced failing-first in tests/test_chronicle_package_directory.py (18 tests). The boundary is now the file in the directory, not the manifest naming it: - fetch-artifact reads every manifest the directory keeps before the publisher is touched and refuses a name or a digest any of them registers hash-only (the reviewed pin's digest before the read, the served bytes' digest before anything is written), refuses to overwrite a file a sibling records as other bytes, and refuses a manifest whose source_id/package_id differ from the fetch's. An artifact may not be named like a manifest, and --manifest must name manifest.yaml or manifest_.yaml. - publish-raw and inventory-artifacts report filename_collision_across_ manifests / sha256_collision_across_manifests (a name or digest public in one manifest and hash-only in another, or public under two digests) and publish nothing under such a directory; the tracked shape of one public file recorded by two manifests as the same bytes is accepted. validate_manifest_files gains sha256_collision within one manifest. - register-artifact takes --manifest with the same stray-default refusal as fetch, refuses a manifest-named filename, and refuses an identity (by name or digest) any manifest in the directory holds public or archived. - The source-package byte reader refuses a file a sibling manifest registers hash-only, by name or digest, before any store is consulted.

manifests strictly and validate every entry field the byte boundary relies on A manifest is the record the byte boundary is decided from, so the reader now refuses what it cannot represent faithfully and the commands validate what they used to act on silently: - StrictManifestLoader refuses a document with duplicate mapping keys (PyYAML keeps the last of two equal keys, so `files:` recorded twice, or a vintage as `2023` and again as `2_023`, would read as one entry and the shadowed entry would be dropped by the next write). - The filename comparison key is NFC-normalised as well as case-folded, so the composed and decomposed spellings of an accented name are one file, as they are on the filesystems these commands run on. - validate_file_entry reports a nameless or malformed entry, a misspelled field (`Access` is not `access`, and an entry whose access class sits under the wrong key is not public by omission), a storage block or a chronicle_fetch attestation on a hash-only entry, a consumer attestation signed by Chronicle, and evidence whose URL has no host; a public release may hold one filename under different vintages but not under two digests in one vintage. - register-artifact validates every existing entry of the manifest before recording into it: an invalid entry is never replaced or reclassified in passing, and the refusal names the same codes inventory-artifacts reports. Covered by tests/test_chronicle_manifest_reading.py; the lane that authored this (fix-227-r2, resumed after lane limits) left it uncommitted, tests green, and it is committed here unchanged.
