chore: L5 KEEP leftover scan after lifecycle barrel deletion

[Drswith]

Summary

Post-L4 L5 leftover scan after src/lifecycle/ barrel deletion (#727) and OpenSpec archive (#728). Import-graph proof that remaining src/services, src/compatibility, src/self, and src/idempotency bridges are still referenced and still add differential behavior (CLI context, port injection, v1 projection, domain planning/providers/binary/lock, idempotency replay). Delete none. Keep every still-imported module and every bridge that still adds differential behavior.

Intake: mechanical leftover scan / no observable behavior — no new OpenSpec change. An actual fold of the published v1 facade or Core-internal engines would be an architecture-boundary change and would need OpenSpec; this PR documents that the fold is not safe.

DELETE vs KEEP

Module	Result	Proof
src/lifecycle/	already DELETED in L4	Ownership test asserts the directory is gone. Do not restore.
src/core/lifecycle/index.ts	KEEP absent	No Core lifecycle barrel (ADR 0011–0014). Ownership test asserts the path is gone.
src/core/lifecycle/{model,provider-binding,provider-evidence,agent-observation,update-planner,agent-execution,uninstall-postcondition}.ts	KEEP	Core-internal engines. Product-path KEEP hang lives here so classify stays product-impacting. Not leftover pass-throughs.
src/self/application.ts	already DELETED in P6	Ownership test asserts the path is gone.
src/core/self-upgrade-production.ts	already DELETED in P6	Would import src/self and fail the Core boundary.
src/services/self-upgrade.ts	already DELETED in P6	No leftover services shim.
src/services/lifecycle-updates.ts / lifecycle-execution.ts	already DELETED in P2	Ownership test asserts the paths are gone.
src/services/index.ts	KEEP	Published v1 facade only (agents + update planning). Importer: src/compatibility/index.ts. P5 already pruned unused production re-exports.
src/services/agents.ts	KEEP	Published v1 resolveAgent / resolveAgentInspection / inspectRegisteredAgents. CLI routes no longer call the inspection helpers; the barrel still publishes them.
src/services/update.ts	KEEP	Published v1 planAgentUpdates grouping. Importer: services barrel.
src/services/self-upgrade-production.ts	KEEP	Differential: CLI context, cancellation, runtime ports, src/self plan/upgrade/lock/persistence binding into Core. Importer: src/commands/upgrade.ts.
src/services/lifecycle-execution-production.ts	KEEP	Differential: human stdio inherit, --install via installation-compatibility. Importer: src/commands/run.ts. L4 only retargeted LifecycleOutcome onto src/core/lifecycle/model.
src/services/lifecycle-updates-production.ts	KEEP	Differential CLI→Core update adapter (operation context, observation/lock ports). Importers: src/commands/update.ts, src/idempotency/lifecycle-policy.ts.
src/services/doctor-diagnosis-production.ts	KEEP	Differential: CLI-coupled observations + Core diagnosis. Importer: src/commands/doctor.ts.
src/services/lifecycle-observations.ts	KEEP	Differential catalog/PATH/latest-version enrichment over Core-internal observeAgentLifecycle.
src/services/core-read-observations.ts	KEEP	Differential v1 enrichment over quantex-core/internal inspect/list.
src/services/provider-observations.ts	KEEP	Differential provider snapshot + frozen v1 installer-id projection.
src/services/command-capabilities.ts	KEEP	Differential command-contract snapshot → frozen v1 capability flags.
src/compatibility/index.ts	KEEP	Published v1 root facade (src/index.ts re-exports it). Folding would change the published command/SDK boundary.
src/compatibility/agent-inspection.ts	KEEP	Differential v1 inspection projector (source/update labels, unmanaged lifecycle).
src/self/index.ts	KEEP	Domain barrel: planSelfUpgrade / upgradeSelf plus lock/planning/facts/release. Published v1 subset via compatibility.
src/self/planning.ts	KEEP	Domain planning. Importer: src/self/index.ts.
src/self/{lock,facts,binary,recovery,registry,release,types,update-metadata,update-notice,state-persistence}.ts	KEEP	Still referenced (CLI, planning, doctor, command-runtime, production ports).
src/self/providers/**	KEEP	Domain providers (bun / npm / binary / source).
src/idempotency.ts	KEEP	Versioned record I/O (TTL, atomic write, parse). Importer: src/command-runtime.ts.
src/idempotency/lifecycle-policy.ts	KEEP	Differential presence/update replay + provider evidence. L4 only retargeted imports onto Core-internal modules.
src/idempotency/{canonical,replay,schema}.ts	KEEP	Canonical fingerprinting, replay decisions, record schema. Not pass-throughs.
src/core/{installation,update}-compatibility.ts / *-production.ts / production-observation.ts / self-upgrade-executor.ts	KEEP	Differential Core ports / compatibility (P2/P6). Not L4 leftovers.
src/commands/unmanaged-install-compatibility.ts	KEEP	Frozen v1 no-op for unmanaged externals.
src/state.ts / src/planning/index.ts / src/inspection/index.ts / src/runtime/index.ts	KEEP	Established convenience barrels with live importers (and, for planning/inspection, published v1 re-exports). Not L4 leftover shells.
packages/core/src/{index,internal}.ts	KEEP	Published SDK root + internal subpath. Frozen: do not expand.

DELETE: none (0 zero-reference modules and 0 pure pass-through leftover wrappers after #727).

Same-file helpers that look unused from outside stay: they are live internals, not leftover bridges. Named re-exports on the published compatibility facade stay: they are the v1 root export surface locked by test/compatibility/v1-baseline.test.ts.

Freeze confirmation

• --json / aliases / exit codes / state v2 / receipt untouched
• --json does not expose engine / route
• Published SDK has no lifecycle helpers; runtime export remains createQuantex
• YAML / release-core.yml / protect-main untouched
• Shelved OpenSpec changes untouched (release-one-line-delivery, release-pr-skip-human-heuristics, windows-ci-advisory-merge-gate)
• Active restore-managed-update-and-resume-releases untouched
• Did not fold config / capabilities / commands / schema
• Did not restore src/lifecycle/

Linked Artifacts

• OpenSpec: not required - mechanical leftover scan / no observable behavior (intake classification)
• ADR: docs/adr/0014-core-internal-lifecycle-barrel-deletion.md (L4 already deleted the barrel; this PR does not restore it)
• Discussion: post-L4 leftover scan L5 (after refactor(core): delete leftover src/lifecycle barrel #727 / chore(openspec): archive lifecycle-barrel-core-internal-l4 #728)

Validation

• bun run memory:check
• bun run lint
• bun run format:check
• bun run typecheck
• bun run test — 176 files / 2152 passed / 5 skipped
• bun run openspec:validate — 25 passed / 0 failed
• Manual freeze smoke: install/ensure opencode --dry-run --json → ok=true, warnings[0].code=DRY_RUN, data.changed=false, exit 0, no engine/route; upgrade --json --check → MANUAL_ACTION_REQUIRED on source install, no engine/route
• SDK import keys remain ["createQuantex"]
• Local classify: run_test_matrix=true / product-impacting
• GitHub CI green on d049304 (classify + lint + governance + ubuntu/windows/macos + Agent Canaries); draft kept

Release Intent

• Release: not applicable - internal leftover scan with no behavior change (KEEP comments + ownership lock only)

Release Summary

• Not applicable - this source PR does not produce a release entry.

Docs Updated

• Not needed for product README (KEEP comments + ownership lock only)

Scope Check

• I did not add a new ad hoc root-level Markdown file.
• I documented KEEP/DELETE inventory in this PR.
• I did not silently expand into YAML / SDK expansion / folding config/capabilities/commands/schema / restoring src/lifecycle/.

Closure Check

• Working tree was clean after commit.
• Branch was pushed and this PR is the active delivery artifact (draft).
• OpenSpec change not required (mechanical).
• Release is not applicable.

Notes

• Investigate-first: file-level scan found zero unused src/services, src/compatibility, src/self, or src/idempotency modules after L4 deleted src/lifecycle/.
• KEEP-only report PR still counts as done — this is not a hard-cut.
• Product-path KEEP comments hang on existing src/core/lifecycle/* paths so classify stays on the full ubuntu/windows/macos test matrix (protect-main unchanged).
• Draft kept after CI green (requested as draft — do not mark ready).
