A supplemental check over every Python file changed by this branch -passes: - -```text -28 files already formatted -``` - -### Wheel and clean-venv smoke - -The first isolated `uv build` attempt could not resolve Hatchling because the -sandbox has no DNS/network access. Retrying with the already cached Hatchling -build components and `--no-build-isolation` succeeded: - -```text -Building source distribution... -Building wheel from source distribution... -Successfully built policyengine_chronicle-0.1.0.tar.gz -Successfully built policyengine_chronicle-0.1.0-py3-none-any.whl -``` - -The wheel was installed with `pip --no-deps` into a newly created temporary -Python 3.14 venv. An isolated import ran from `/private/tmp`, loaded -`chronicle` from that venv's `site-packages`, imported `chronicle.epoch`, and -asserted the Ledger default and registered fact prefix: - -```text -wheel epoch import smoke: PASS -``` - -### Immutability and review checks - -- `git diff --check`: PASS. -- No changed paths under `releases/`, `chronicle/fixtures/`, `docs/schemas/`, - `policyengine_chronicle/schemas/`, or `.github/chronicle-agents.yml`. -- Frozen fixture SHA-256 assertions pass: - - `facts.jsonl`: `b0dd06765db7932c16a678b1ab321a7d908af26e2f2014d7da99c0eb5127e401` - - `consumer_facts.jsonl`: `6123f1cca28ccc72c053b105b8d50b5c25a72a5f5b92e73e7219f32de152a96a` - - `soi_table_1_1_2023_cells.jsonl`: `615639f21ee63e54595c677e24c3eddff484c00a795a2f91b45a8575f021c7e2` -- Both frozen consumer-schema copies remain - `76ac268e626c86146cee51193e0cbecbb197ddbf3bf410156fe7da7c0edae3ad`. -- Independent `ledger-contract` judge: **PASS**. Identifier normalization - preserves publisher values, reference periods, provenance, and lineage; no - Microcosm contract responsibility moved into Chronicle. -- Independent `ledger-boundary` judge: **PASS**. No reconciliation, aging, - imputation, support-aware activation, solver construction, target profile, or - model-measurement binding was added. -- `ledger-source-fidelity`: not required for the selected contract-maintainer - role; no source facts or publisher artifacts changed. - -## Consumer validators required before any emit flip - -The following are identified by Max's #143 migration spec and Chronicle's own -handoff docs/tests/workflows. They are not changed in this Chronicle PR: - -1. **Microcosm `require_pins` and facts-only artifact/target-contract load** - must accept both consumer-artifact IDs (`policyengine_ledger...v2` and - `policyengine_chronicle...v3`), both consumer-row schema IDs, all Ledger and - Chronicle fact-key domains, and mixed-epoch rows. Exact key verification must - infer the epoch from each row key. Chronicle's - `docs/target-construction-harness-plan.md` assigns hash-pinned artifact and - fact resolution to Microcosm CI. -2. **Brier append gate** must accept both naming epochs and recompute keys from - the epoch declared by each key, byte-identically with Chronicle. The separate - external assertion-ID (`av2`) contract remains in force. -3. **Vidimus `append_gate` and `release_chain`** must dual-accept the updated - pins/specs and complete the required fresh byte-equivalence proof at - Chronicle's current pin before consumption moves. -4. **Chronicle-hosted Thesis append workflow** must exercise those Vidimus - changes in both trusted-base and ordinary `check_thesis_facts_append.py` - paths, including `tests/test_policyengine_chronicle.py`, - `tests/test_release_chain.py`, and - `tests/test_thesis_append_adversarial.py`. - -Scope distinctions: `microcosm-dynamics` is explicitly outside this migration; -Thesis branch-string pin tools are mechanism 2; and María's publish-flow naming -is mechanism 3. None is part of this acceptance-only code change. - -## Residual risks - -- Emit must not flip until the consumer validators above are proven dual-epoch - capable. This PR intentionally leaves `EMIT_EPOCH` at Ledger. -- Bundle ingestion intentionally preserves its historical permissive behavior - for non-identity row shape/type errors; strict row-shape and hash validation - remains at the consumer-artifact boundary. -- Supabase mirror loading remains an opaque transport. It already accepts - arbitrary row values, including Chronicle-era keys, but does not reject an - unknown key domain itself. -- Bundle, coverage, and source-list metadata have no readers in this repository; - their successor schema IDs are therefore registry-only until a reader exists. -- The repository-wide Ruff format baseline remains red in the eight untouched - files listed above. Reformatting them would widen this migration PR without - changing its behavior. -- Retired target-profile and resolved-target v1 contracts deliberately have no - Chronicle successor. Reintroducing them would violate the current facts-only - ADR and consumer boundary.
