[Epic][M0] Runtime Fidelity + Context Normalization

[Prekzursil]

Scope

Deliver deterministic attach/profile selection and dependency-aware safety across STEAMMOD, MODPATH, StarWarsG, and command-line-inaccessible sessions.

Acceptance Criteria

• Runtime and tools/detect-launch-context.py produce matching recommendations on fixture cases.
• ProcessLocator emits normalized LaunchContext and legacy bridge metadata.
• Dependency validation supports workshop roots and local MODPATH marker resolution.
• Attach continues on dependency soft-fail with action gating; hard-fail only on malformed/unsafe metadata.
• Deterministic tests cover parser/recommendation/dependency matrix.

Roadmap Link

• PLAN.md -> M0: Runtime Fidelity and Launch-Context Normalization

[Prekzursil]

M0 carryover reconciliation pass completed for this cycle:\n\n- Closed #15, #16, #17, #18 with evidence comments\n- Seeded M1 execution slices #30, #36, #35, #31, #33, #34\n\nM0 epic can remain open for future drift fixes, but current blocker set is resolved for M1 progression.

M0 closure evidence (deterministic/runtime-fidelity gates)

Acceptance mapping:

• Host/process + launch-context fidelity parity: PASS
• Dependency validator workshop/local marker behavior + soft-fail gating: PASS
• Attach hint path continues to consume launch-context recommendation in app: PASS (app attach diagnostics still sourced from LaunchContext recommendation/reason)

• Result: Passed 99, Failed 0, Skipped 0

Merged implementation context:

• PR M3/M4 full-issue closure wave: onboarding, ops hardening, release strategy #48 (merge commit 442760c) contains the final deterministic M0-supporting hardening and evidence contracts.

Closing #6 as acceptance is fully evidenced in deterministic scope.
