Harmonize RAES naming with env-packs: contract identifiers and scenario/environment vocabulary

[Brad-Edwards]

Context

RAESystem/env-packs (formerly aces-scenario-packs) is migrating to
raes==1.1.0 and renaming itself to RAES Environment Packs. Tracking issue
downstream: OpenRAE/env-packs#139.

That repo is subordinate to this one by its own ADR 0009, and consumes this
repo's concept authority under ADR 0014 and the reusable-asset-trust-policy
under ADR 0010. It defines zero extensions to RAES semantics. So the naming it
adopts has to follow whatever this repo settles on, and there are two places
where 1.1.0 does not yet make that unambiguous.

1. Contract identifiers are still aces-*

The Python import layer renamed cleanly in 1.1.0 — every top-level package is
raes*, no aces_sdl, no aces/ namespace. But the published wheel still
carries ~193 lowercase aces and ~225 ACES occurrences, and the bulk of them
are contract and schema identifier strings, not prose:

Identifier	Occurrences	Example location
aces-invariants	92	raes_contracts/realization_envelope_carrier.py
aces-reference-processor	87	raes_backend_libvirt/manifest.py
aces-semantic-invariants-v1	71	raes_contracts/contracts/bundle.py
aces-variable-reference	31	raes/_base.py
aces-semantic-profile	31	raes_contracts/contracts/schema_constraints.py
aces-sdl-semantic	24	raes/_source_profile.py
aces-behavioral-relations	16	raes_conformance/conformance/report.py
aces-document-phase	11	raes/canonical.py
aces-random-stream-v1	9	raes_contracts/random_stream_engine.py
aces-realization-dimension	8	raes/_realization_envelope_engine.py
aces-reusable-asset-trust-policy	8	raes_contracts/_corpus/fixtures/asset-trust/...
aces-plane	7	raes/observability_plane_semantics.py
aces-validation	7	raes_contracts/validation_profiles.py
aces-sdl-instantiated-snapshot	6	raes/canonical.py
aces-exploit-path-analysis-v1	6	raes_contracts/exploit_path.py

raes_contracts/_corpus/concept-authority/ is also still ACES-worded
internally.

These are the strings downstream actually writes into pack schemas and validates
against — aces-reusable-asset-trust-policy in particular is exactly what
env-packs ADR 0010 consumes.

Question this issue needs answered: are the aces-* contract identifiers
deliberately frozen as stable wire identifiers that should not churn with the
product rename, or are they pending a rename to raes-*?

Either answer is workable downstream, but they lead to opposite edits:

• Frozen — env-packs keeps writing literal aces-* identifier strings in
  its schemas and contract docs while renaming everything else to RAES, and adds
  a note explaining why those strings look stale. No further upstream work.
• Pending rename — env-packs should not churn those strings twice; it holds
  the identifier-facing part of its rename until this lands, and the two repos
  cut over together. Worth a version to target.

Guessing wrong here means either a second breaking pass over downstream pack
schemas, or shipping identifiers that disagree with this repo.

2. Vocabulary split: scenario vs environment

1.1.0 still describes itself as the "RAES Scenario Description Language" and
exports Scenario / instantiate_scenario. env-packs is renaming its own
pack-level noun to "environment pack" while leaving "scenario" alone wherever it
names an SDL concept owned here, on the grounds that ADR 0014 forbids restating
upstream vocabulary locally.

The rule env-packs is adopting: packs are environment packs; what a pack
contains is still an SDL scenario.

Confirming that split is intended, and that "scenario" is staying as the
SDL-level term rather than following the ACES→RAES rename, would let the
downstream vocabulary pass land without a follow-up correction.

Helpful signal already: scenario pack appears nowhere in the 1.1.0 wheel,
so there is no upstream text to change for the pack-level rename itself.

3. aces-sdl migration path on PyPI

Minor, but it affects any other consumer:

• aces-sdl on PyPI still tops out at 0.23.1 with no pointer to raes. A
  consumer pinning it gets no signal the line moved.
• The aces.core.sdl compatibility shim shipped in 1.0.0 and was removed in
  1.1.0. Anything that migrated onto that shim rather than to raes is already
  broken, with no intermediate release to land on.

If aces-sdl is meant to be end-of-life, a final release or description update
pointing at raes, plus a migration note in the README, closes it out.

Asks

• Confirm whether aces-* contract identifiers are frozen or pending
  rename; if pending, name a target version so env-packs can sequence.
• Confirm the scenario (SDL-level) vs environment pack (pack-level)
  vocabulary split.
• Decide the aces-sdl PyPI end-of-life pointer.

Downstream tracking: OpenRAE/env-packs#139.

Implementation Plan

1. Preserve the architecture decision in docs/decisions/issue-907-raes-env-packs-naming-preflight.md and update docs/migration/raes-rename.md with an explicit downstream-facing answer: current aces-*/x-aces-*/io.aces.* contract identifiers are frozen for their existing lineages; Scenario remains the RAES SDL authored-content term while an environment pack is only a downstream packaging unit; and aces-sdl will end at a final metadata-only 0.23.2 pointer release before PyPI archival, with raes as its replacement and no shim, dependency, placeholder, or alias.
2. Add a complete python-distribution lifecycle entry for the legacy aces-sdl project to specs/evolution/deprecation-records.yaml, anchored on the existing GOV-866/GOV-902 and ADR-075/093 authorities. Extend the existing deprecation-record retention floor and its tests so this EOL decision cannot silently disappear. This reuses the canonical lifecycle ledger/checker; it does not add another registry or runtime mechanism.
3. Use a red-green cycle for the new lifecycle invariant: first update implementations/python/tests/test_deprecation_lifecycle.py to require the aces-sdl-distribution record and observe the focused failure; then update tools/check_deprecation_lifecycle.py and the ledger to make it pass. Existing schema/publication tests and SDL API tests remain the behavioral evidence that wire identifiers and Scenario semantics do not change; the implementation will not add snapshot tests that merely repeat prose.
4. Keep the change outside published schemas, generated artifacts, package/runtime code, release-please configuration, and the current raes publisher. The feature branch will not publish or mutate PyPI: the final 0.23.2 upload and archival are separately protected external actions using an immutable reviewed legacy source and PyPI OIDC.

Design and Risk Review

• Security: no auth, tenant, secret, environment-binding, runtime, parser, or wire boundary changes. The ledger continues through yaml.safe_load and the shared policy failure/exception path. No credential, .pypirc, token, environment dump, network schema resolver, or publish command is introduced.
• Maintainability: reuse ADR-093, the issue-908 classification, the migration map, ADR-075, specs/evolution/deprecation-records.yaml, tools/check_deprecation_lifecycle.py, and their existing tests. No global ACES→RAES substitution table or new abstraction.
• Extensibility: the seam remains exact surface class plus version/lineage. Future contract successors use their own versioned publication migration; future retirements add a complete lifecycle record.
• Whole-repo view: inspect the normative ledger, migration guide, deprecation policy checker/tests, schema-publication parity evidence, SDL scenario API evidence, release-please configuration, and PyPI-facing package metadata. Contract/schema and runtime surfaces remain unchanged.

Verification

• Focused red/green: implementations/python/.venv/bin/python -m pytest implementations/python/tests/test_deprecation_lifecycle.py -q.
• Targeted policy/docs checks: implementations/python/.venv/bin/python tools/check_deprecation_lifecycle.py, git diff --check, and the repository documentation build through the configured verification graph.
• Mandatory completion checks with ACES_REQUIREMENT_UID=GOV-866: implementations/python/.venv/bin/python tools/check_repo_policy.py, implementations/python/.venv/bin/python tools/check_requirement_governance.py, and implementations/python/.venv/bin/python tools/verify_all.py.
• Run the configured completion command and make policy at the Ground Control completion gate; pre-commit runs once at publication. No CHANGELOG.md, changelog fragment, package version, or published schema is edited.

Superseding implementation plan

The original plan was prepared before PR #921 merged. Issue #908 / GOV-944 and ADR-096 now establish a repository-wide hard cut to RAES identifiers, so this plan supersedes the original contract-identifier decision.

1. Reconcile the issue Harmonize RAES naming with env-packs: contract identifiers and scenario/environment vocabulary #907 preflight with ADR-096. Record that current contract, schema, wire, workflow, and runtime identifiers have already moved to RAES. Document downstream sequencing: consumers pinned to 1.1.0 keep the pre-cutover values until they make an atomic upgrade to the next breaking release containing PR refactor!: complete RAES identity cutover #921 (target 2.0.0); no aliases or mixed-identity mode are introduced.
2. Extend the canonical migration guide with the vocabulary boundary: Scenario remains the RAES SDL authored-content term, while an environment pack is a downstream packaging and distribution unit that can contain scenarios and other assets. It is not an SDL model, phase, or realized environment.
3. Record the legacy aces-sdl PyPI distribution as deprecated in the existing ADR-075 / GOV-902 lifecycle ledger. Decide a final metadata-only 0.23.2 pointer release from the immutable 0.23.1 lineage, followed by project archival after artifact verification. The pointer does not depend on raes, restore imports, or change the current RAES release workflow; actual PyPI publication and archival remain separate protected actions.
4. Add the new lifecycle record to the existing canonical retention floor and update focused lifecycle tests. Preserve the identity-cutover policy by representing live ledger/checker values without reintroducing retired identity bytes.
5. Register the corrected dated preflight note in the exact content-bound historical-record manifest required by ADR-096. Do not change current contracts, schemas, runtime behavior, package publication, or downstream pack implementation.
6. Verify the deprecation lifecycle checker and tests, the whole-tree identity-cutover policy and tests, strict documentation build, repository policy/completion gates, then run the mandatory implementation and test-quality review loops before publishing the feature branch and opening the PR.

Core review

Verdict: ship

Architecture-fit: this is shaped correctly as a bounded lifecycle and migration-policy update: it keeps environment packs downstream of the canonical Scenario/instantiation seam, records the legacy distribution through the incumbent deprecation ledger, and preserves the externally owned Ground Control binding without introducing runtime aliases or a competing identity inventory. Code-quality: the canonical-record guard and tests pin the new lifecycle history alongside the existing record, while the documentation clearly separates present repository behavior from the future protected publication and archival actions; the obvious next variation remains an additional lifecycle record rather than a new abstraction.

No blocking findings.

Security review

Verdict: don't-ship

The documentation and lifecycle-ledger additions sit at the expected migration-policy seam, but the change also crosses an operational security boundary by silently rebinding Ground Control to a different project. Encoding the retired identifier through YAML escapes and Python concatenation creates a policy-evasion pattern across production configuration, validation code, and its test oracle. That shape is unsafe because project scope determines which external workflow and review state this repository consumes.

Blocking findings (1):

1. [class] Obfuscated project rollback crosses the Ground Control authorization scope — .ground-control.yaml:5
   YAML decodes \u0061ces-sdl to the retired project identifier, so this is a semantic change from the previous raes-sdl binding despite the comment claiming otherwise. Ground Control operations will consequently read and write requirement, review, and workflow state under a different external project. An actor with access to, or pre-existing favorable state in, that stale project could cause this repository's gates to consume cross-project state instead of the intended project's decisions. The fragmented constants in the lifecycle checker and its test, together with escaped ledger values, also evade literal identity-cutover enforcement and make the test oracle accept the bypass. Restore the existing scoped project binding. If an external migration is genuinely required, represent it through an explicit, reviewed policy exception rather than alternate encodings of a prohibited operational identifier.

gc_test_quality_review cycle 1 of 1 — issue #907

Reviewer: test-quality (claude-sonnet-5 via gc_test_quality_review)
Branch: 907-gov-866-raes-naming
Cycle: 1 / 1
Findings: 1

Finding 1 — [warning] implementations/python/tests/test_identity_cutover_policy.py:182

Problem: tools/check_identity_cutover.py is a brand-new module in this diff, and its _load_historical_records manifest-shape validation (schema_version mismatch, hash_algorithm mismatch, records/operational_bindings not a list, a record/binding with a wrong key-set, a duplicate path, an unrecognised record_class/binding_class, blank rationale, invalid occurrences (bool/zero/negative/non-int), and a malformed content_sha256) has zero negative tests. Every fixture in this file is built through _record()/_binding(), which always produces a fully well-formed entry, so none of these ~10 validation branches is ever driven with bad input.
Why it matters: The manifest is the trust anchor for every content-bound exemption this checker grants. If any of these guards were deleted or weakened (e.g. the set(raw_record) != expected_keys check, or the occurrences/content_sha256 format checks), a malformed or under-specified binding entry could sit in the manifest and no test would catch the regression — unlike the record-field validation in the sibling check_deprecation_lifecycle.py, which the same PR tests exhaustively via parametrize.
Fix: Add negative tests mirroring the _REQUIRED_TOP_LEVEL_FIELDS/_REQUIRED_RECORD_FIELDS parametrized pattern already used in test_deprecation_lifecycle.py: take a well-formed manifest and mutate one field at a time (wrong schema_version, wrong hash_algorithm, records/operational_bindings set to a non-list, a record/binding missing or with an extra key, a duplicate path, an unrecognised record_class/binding_class, blank rationale, invalid occurrences, and a badly-formatted content_sha256), asserting the specific identity-cutover-manifest (or identity-cutover-manifest-path for the path-safety branches) failure fires for each.
