v0.8 close-out: tier integration into life-package.schema.json + auto-compute builder + status docs

[devin-ai-integration]

Summary

Final integration PR that closes out the v0.8-asset-architecture epic (#106). Weaves the standalone schemas/tier.schema.json (shipped in #113) into the top-level schemas/life-package.schema.json so v0.8 builders emit a single descriptor that carries the tier block, and teaches tools/build_life_package.py to auto-compute that block at build time. Also refreshes the long-lived status documents (IMPLEMENTATION_STATUS.md, GAP_ANALYSIS.md, ROADMAP.md, CHANGELOG.md) to reflect the v0.8 release.

Schema integration

• schemas/life-package.schema.json
  • Adds an optional top-level tier property that $refs #/$defs/tier_block.
  • Inlines $defs.tier_block + $defs.tier_dimensions copied verbatim from schemas/tier.schema.json, so offline validators do not need to resolve cross-file $ref (same pattern the repo already uses everywhere else).
  • Marks verification_level as deprecated in v0.8 in the description text while keeping it required for v0.1 back-compat. Points at docs/LIFE_TIER_SPEC.md §6 for the migration mapping.
  • v0.7 packages (no tier) keep validating; v0.8 packages (with tier) are additionally score↔level consistency-checked via the 12 allOf bands.
• tools/test_life_package_schema.py
  • +10 new sanity cases (54 → 64 total): tier omitted, tier present + consistent (score 54 → VII), lowest-bound (0 → I Quark), highest-bound (100 → XII Singularity), score↔level mismatch rejection, hand-rolled computed_by rejection, score > 100 rejection, off-enum dimension, missing required dimension, unknown field.

Builder auto-compute

• tools/build_life_package.py v0.2
  • Adds _compute_tier that deterministically maps v0.7 verification_level → v0.8 identity_verification (per docs/LIFE_TIER_SPEC.md §6), infers asset_completeness from capability-bearing top-level directories, and defaults the remaining four dimensions conservatively.
  • Applies the normative weighted-average formula (identity & consent ×2, others ×1) then bands the rounded result into the 12 Schema D tiers (Quark → Singularity). All 12 bands are generated from the same _TIER_BANDS table used by the schema, so any drift is a test-visible bug.
  • Stamps computed_by = "tools/build_life_package.py@0.2.0"; the mandatory @<version> separator is schema-enforced, so hand-rolled tier blocks fail validation.
  • Adds six --tier-<dim> CLI overrides for issuers who can declare higher-than-default levels (e.g. a studio-recorded voice asset → --tier-detail-level high_fidelity) and a --no-tier escape hatch for emitting v0.7-shaped descriptors.
• tools/test_minimal_life_package.py now asserts the emitted descriptor contains a well-formed tier block with all 6 dimensions and an @-separated computed_by.

Spec / status doc refresh

• docs/LIFE_FILE_STANDARD.md — adds the tier row to the descriptor table; marks verification_level as deprecated with a pointer to docs/LIFE_TIER_SPEC.md §6.
• docs/IMPLEMENTATION_STATUS.md — bumps to doc version 6.0; adds v0.8 increment summary; overall maturity ~80% → ~82%.
• docs/GAP_ANALYSIS.md — baseline moves to post-[EPIC] v0.8 — Asset Architecture (Genesis / Lifecycle / Binding / Tier / Assembly) #106; .life Archive Standard 70% → 82%; .life Runtime Standard 30% → 45%.
• ROADMAP.md — marks life-format v0.1.0 and life-runtime v0.1 as Delivered; adds life-format v0.1.1 (Asset Architecture) and life-runtime v0.1.1 (Assembly) rows as Delivered under v0.8-asset-architecture; reference runtime deferral moved from v0.8+ → v0.9+.
• CHANGELOG.md — v0.8-asset-architecture stanza flipped from Draft → Released; new entries describing the tier integration + builder v0.2 + status doc bumps.

Local verification

• python tools/test_life_package_schema.py → all 64/64 cases pass.
• python tools/test_minimal_life_package.py → OK (descriptor valid, contents inventory matches, audit chain links, deterministic bytes across two builds).
• python tools/batch_validate.py → 22/22 passed.

Review & Testing Checklist for Human

• Confirm the inlined $defs.tier_block / $defs.tier_dimensions in life-package.schema.json stays byte-for-byte identical to schemas/tier.schema.json (the repo has no automated drift check yet; future signature/cross-schema PR should add one).
• Spot-check the _compute_tier defaults in tools/build_life_package.py — conservative defaults are intentional (consent_completeness: text_only, audit_chain_strength: linked, jurisdiction_clarity: unspecified). If the org expects a different default for the demo record, issuers can lift them with the new --tier-* flags.
• Verify the new tier row in docs/LIFE_FILE_STANDARD.md reads correctly and the verification_level deprecation note is visible.

Notes

This is the spec-layer close-out for v0.8. It is not the start of v0.9 runtime implementation. No runtime code is added; the builder is the only code change and its behaviour remains deterministic + offline + pointer-mode.

Closes out epic #106 follow-up (integration). Sub-issues #100–#105 were already merged via PRs #107, #108, #110, #111, #113, #115; follow-ups #109, #112, #114, #116 merged alongside.
