ShyftR Phase 7 P7-1 closeoff

Date: 2026-05-15 Repo: /Users/stefan/ShyftR Phase: Phase 7 — privacy, policy, and safety hardening Tranche: P7-1 — policy/authority baseline Status: complete locally, verified green, ready to commit Predecessor closeoff: /Users/stefan/ShyftR/2026-05-15-shyftr-phase-6-closeoff.md Planning artifacts:

  • /Users/stefan/ShyftR/2026-05-15-shyftr-phase-7-tranche-p7-0-plan.md
  • /Users/stefan/ShyftR/2026-05-15-shyftr-phase-7-handoff-packet.md

Final verdict

P7-1 is complete on the intended local implementation surface.

The tranche landed a narrow authority-first and privacy-first hardening slice that keeps durable direct-write behavior conservative by default, preserves compatibility with older approved memory rows, deepens nested sensitive-metadata redaction, and keeps provider/readiness surfaces green after the new gating behavior was introduced.

What landed

  1. Direct-write authority baseline

    • provider durable writes now evaluate an explicit direct-write policy.
    • rule-class durable memory is gated by default and remains pending review unless explicitly allowed.
    • non-rule durable writes that remain within the reviewed baseline still promote successfully.

  2. Compatibility-safe policy helpers

    • DirectWritePolicy and DirectWriteDecision were added as additive helpers.
    • authority is resolved through the existing memory-class layer rather than a new policy engine.
    • default behavior remains review-gated and compatibility-safe.

  3. Nested privacy redaction deepening

    • sensitive rows now redact nested sensitive metadata fields recursively.
    • safe display fields remain visible where appropriate.
    • statement redaction behavior remains intact for sensitive rows.

  4. Append-only compatibility tolerance

    • approved memory rows can now tolerate compatibility hash fields such as row_hash and previous_row_hash during deserialization.
    • older rows continue to round-trip without schema breakage.

  5. Provider/readiness compatibility reconciliation

    • provider pack() again exposes selected_ids and emits pack diagnostics expected by readiness and replacement tests.
    • provider record_signal() again routes through the runtime outcome path and returns accepted/outcome identifiers expected by existing tests.
    • provider snapshot export/import again delegates to readiness snapshot helpers so replacement-readiness behavior remains intact.

  6. Baseline harness reconciliation

    • current-state baseline fixture seeding now explicitly allows direct durable fixture writes when required by the new rule-memory gate.
    • seeded fixture memories fail fast if they do not promote, making authority regressions easier to detect.

  7. Documentation hygiene needed for repo-wide green

    • Phase 6 closeoff wording was minimally normalized so public-vocabulary checks remain green after this tranche.
    • the Phase 7 handoff packet was intentionally left unmodified for final state; the canonical stop-point artifact for this tranche is this closeoff file.

New and updated tests

New focused Phase 7 tests:

  • tests/test_phase7_policy_authority.py
  • tests/test_phase7_privacy_redaction.py

Existing coverage that now validates the tranche indirectly:

  • tests/test_privacy_sensitivity.py
  • tests/test_memory_provider.py
  • tests/test_pack.py
  • tests/test_current_state_metrics_schema.py
  • tests/test_current_state_phase2_metrics.py
  • tests/test_memory_vocabulary_guard.py
  • tests/test_replacement_readiness.py

Verification

Focused Phase 7 checks:

  • cd /Users/stefan/ShyftR && PYTHONPATH=.:src pytest -q tests/test_phase7_policy_authority.py tests/test_phase7_privacy_redaction.py tests/test_privacy_sensitivity.py tests/test_memory_provider.py tests/test_pack.py tests/test_phase6_resource_memory_privacy.py tests/test_phase6_resource_memory_schema.py
  • result: 78 passed

Reconciliation checks for repo-wide blockers discovered during tranche verification:

  • cd /Users/stefan/ShyftR && PYTHONPATH=.:src pytest -q tests/test_replacement_readiness.py tests/test_current_state_metrics_schema.py tests/test_current_state_phase2_metrics.py tests/test_memory_vocabulary_guard.py tests/test_phase7_policy_authority.py tests/test_phase7_privacy_redaction.py
  • result: 16 passed

Repo-wide verification:

  • cd /Users/stefan/ShyftR && PYTHONPATH=.:src pytest -q
  • result: 976 passed, 31 warnings
  • cd /Users/stefan/ShyftR && PYTHONPATH=.:src python -m compileall -q src scripts examples → pass
  • cd /Users/stefan/ShyftR && python scripts/terminology_inventory.py --fail-on-public-stale → pass
  • cd /Users/stefan/ShyftR && python scripts/terminology_inventory.py --fail-on-capitalized-prose → pass
  • cd /Users/stefan/ShyftR && python scripts/public_readiness_check.py → PASS
  • cd /Users/stefan/ShyftR && git diff --check → pass

Implementation touchpoints

Core code updated:

  • src/shyftr/policy.py
  • src/shyftr/privacy.py
  • src/shyftr/provider/memory.py
  • src/shyftr/models.py
  • scripts/current_state_baseline.py

Docs updated:

  • 2026-05-15-shyftr-phase-6-closeoff.md
  • 2026-05-15-shyftr-phase-7-p7-1-closeoff.md

Tests added:

  • tests/test_phase7_policy_authority.py
  • tests/test_phase7_privacy_redaction.py

Scope boundary reached

This tranche intentionally stops at the P7-1 baseline:

  • authority defaults are pinned;
  • nested redaction expectations are pinned;
  • compatibility-safe contradiction representation is covered at the provider/pack level without broader contradiction machinery;
  • no broader poisoning or prompt-injection framework was introduced yet.

That later work remains for:

  • P7-2 privacy/export/redaction deepening
  • P7-3 contradiction and poisoning fixtures
  • P7-4 review-surface and policy-visibility improvements
  • P7-5 broader safety verification and final Phase 7 closeoff

Swarm attribution

A background swarm builder lane was attempted during the tranche but did not produce landed output and was terminated. The actual implementation, reconciliation, and verification for the committed tranche state were completed directly in the local repo session.

Git and release state

Pre-commit verified repo state for this closeoff:

  • branch: main
  • remote: origin https://github.com/stefan-mcf/shyftr.git
  • git identity: stefan-mcf <73107236+stefan-mcf@users.noreply.github.com>
  • local verification: green before commit

Outcome

ShyftR now has a complete P7-1 baseline for Phase 7:

  • conservative authority defaults for direct durable writes
  • explicit override path for gated rule-class durable memory
  • deeper nested sensitive-metadata redaction
  • compatibility tolerance for append-only hash fields
  • preserved provider/readiness behavior across pack, signal, and snapshot surfaces
  • full repo green verification

One-line summary

Phase 7 P7-1 is done locally: ShyftR now enforces an authority-first direct-write baseline, deepens nested privacy redaction, preserves append-only compatibility, and remains repo-wide green.
