 1# Branch A Validation Report
 2
 3- Branch: `branch-a/task04-validation-reporting`
 4- Base commit: `164c06af63812c69cab32d8f8a6c770b96f38ef6`
 5- Overall status: `PASS`
 6- Ready for review/comparison: `True`
 7
 8## Runtime Summary
 9- Status: `PASS`
10- Scenarios: interface, smoke, dynamics, sedimentation, snapshot
11- Output modes observed: full, degraded, minimal
12
13## Interface Checks
14- Status: `PASS`
15- Passed: `2`
16- Failed: `0`
17- `PASS` runtime_initializes: A fresh runtime exposes minimal output mode and no active region.
18- `PASS` locked_interface_presence: Branch A exposes the locked runtime interface required by the spec.
19
20## Smoke Checks
21- Status: `PASS`
22- Passed: `4`
23- Failed: `0`
24- `PASS` ingest_queues_signal: Ingest stores external tokens and anchor hints before the step loop runs.
25- `PASS` step_materializes_graph_state: Stepping from a queued input creates observable phi/mu/J state.
26- `PASS` emit_queues_output_feedback: Emit creates a real output-to-input feedback signal rather than a log-only artifact.
27- `PASS` feedback_changes_later_state: Queued feedback is applied on the next step and changes later runtime state.
28
29## Dynamics Checks
30- Status: `PASS`
31- Passed: `4`
32- Failed: `0`
33- `PASS` phi_mu_J_are_observable: Multi-step dynamics produce visible changes across phi, mu, and J.
34- `PASS` homing_signals_are_populated: The runtime exposes bound_ability_core, anchor_pull, and drift_score as active homing signals.
35- `PASS` decay_and_forgetting_are_visible: Decay/forgetting remains real and observable through decay events and stage demotion.
36- `PASS` degraded_output_modes_exist: The runtime emits full, degraded, and minimal outputs under different runtime conditions.
37
38## Sedimentation Checks
39- Status: `PASS`
40- Passed: `4`
41- Failed: `0`
42- `PASS` sedimentation_trace_exists: Sedimentation history is exported as explicit runtime trace entries.
43- `PASS` stage_progression_matches_locked_path: Repeated activation follows the locked memory -> experience -> skill_belt -> ability_core path.
44- `PASS` skill_belt_candidates_have_evidence: Skill-belt candidates are backed by repeated activation, stability, and flow evidence.
45- `PASS` merge_events_are_recorded: Stable skill-belt structures can produce explicit merge events into ability-core structures.
46
47## Snapshot Checks
48- Status: `PASS`
49- Passed: `4`
50- Failed: `0`
51- `PASS` locked_snapshot_fields_present: snapshot_state returns the locked comparable field set.
52- `PASS` summary_fields_are_meaningful: phi_summary, mu_summary, and J_summary expose non-empty observable summaries after activity.
53- `PASS` feedback_and_output_fields_are_populated: snapshot_state exposes output_mode and feedback_effect with applied feedback evidence.
54- `PASS` locked_homing_and_sedimentation_fields_are_populated: The locked homing and sedimentation-facing snapshot fields are populated under a controlled scenario.
55
56## Known Limitations
57- The validation harness is scenario-based and compact; it is not a benchmark or long-run stability suite.
58- Checks focus on the locked observable runtime surface rather than richer semantic task performance.
59- Sedimentation and homing remain explicit but heuristic, which is acceptable for the review/comparison stage.
60
61## Readiness
62- Branch A validation passed and is ready for review/comparison.
