# Structured Fail-Closed Improvement Roadmap Closure Report
|
|
|
|
> Date: 2026-04-19
|
|
> Plan: `docs/superpowers/plans/2026-04-19-structured-fail-closed-improvement-roadmap-plan.md`
|
|
> Status: Closed
|
|
|
|
## Scope
|
|
|
|
This roadmap handled the `48` structured fail-closed records from the reconciled `102` scene sweep.
|
|
|
|
The roadmap boundary explicitly excluded:
|
|
|
|
1. new scene families
|
|
2. `G4/G5`
|
|
3. login recovery
|
|
4. full host runtime transport
|
|
5. local document attachment runtime
|
|
6. `scene_execution_board_2026-04-18.json` updates
|
|
7. direct scene promotion
|
|
8. timeout implementation work
|
|
9. readiness gate relaxation
|
|
|
|
Those boundaries were preserved.
|
|
|
|
## Completed Phases
|
|
|
|
### Phase 0: Freeze Structured Fail-Closed Baseline
|
|
|
|
Completed.
|
|
|
|
Input baseline:
|
|
|
|
| Status | Count |
|
|
| --- | ---: |
|
|
| `auto-pass` | 48 |
|
|
| `fail-closed-known` | 48 |
|
|
| `adjudicated-valid-host-bridge` | 4 |
|
|
| `source-unreadable` | 2 |
|
|
| Total | 102 |
|
|
|
|
Only `fail-closed-known` records entered the inventory phase.
|
|
|
|
### Phase 1: Inventory and Gap Taxonomy
|
|
|
|
Completed.
|
|
|
|
Deliverables:
|
|
|
|
1. `tests/fixtures/generated_scene/structured_fail_closed_inventory_2026-04-19.json`
|
|
2. `docs/superpowers/reports/2026-04-19-structured-fail-closed-inventory-report.md`
|
|
|
|
Inventory summary:
|
|
|
|
| Primary label | Count |
|
|
| --- | ---: |
|
|
| `enrichment_request_missing` | 23 |
|
|
| `export_plan_missing` | 12 |
|
|
| `local_doc_contract_missing` | 5 |
|
|
| `mode_request_contract_missing` | 4 |
|
|
| `single_request_enrichment_contract_missing` | 2 |
|
|
| `bootstrap_target_unresolved` | 2 |
|
|
|
|
The `paginated_enrichment` bucket was split into:
|
|
|
|
| Primary label | Count |
|
|
| --- | ---: |
|
|
| `enrichment_request_missing` | 23 |
|
|
| `export_plan_missing` | 12 |
|
|
|
|
### Phase 2: G3 Paginated Enrichment Recovery Slice
|
|
|
|
Completed as a bounded evidence-preservation slice.
|
|
|
|
The top repeated G3 gap was `enrichment_request_missing`, but there was not enough traceable evidence to safely synthesize missing enrichment requests without relaxing the `G3` contract.
|
|
|
|
Instead, the implementation improved structured fail-closed observability by embedding `contractSnapshot` in pre-package fail-closed reports. This preserves the full `SceneIr` for future recovery analysis while keeping the result fail-closed.
|
|
|
|
Changed implementation:
|
|
|
|
1. `src/generated_scene/generator.rs`
|
|
2. `tests/scene_generator_test.rs`
|
|
|
|
This slice did not:
|
|
|
|
1. hardcode scene names
|
|
2. relax gates
|
|
3. convert incomplete `G3` records into pass
|
|
4. change canonical `G3` behavior
|
|
|
|
### Phase 3: Small-Bucket Recovery Slice
|
|
|
|
Completed as inspection and explicit deferral.
|
|
|
|
Deliverable:
|
|
|
|
`docs/superpowers/reports/2026-04-19-structured-fail-closed-small-bucket-decision-report.md`
|
|
|
|
No small-bucket implementation slice was started because the largest remaining value stayed in the `G3` structured fail-closed bucket, and the plan allowed at most one non-G3 bounded slice.
|
|
|
|
### Phase 4: Bootstrap Target Isolation
|
|
|
|
Completed.
|
|
|
|
Deliverable:
|
|
|
|
`docs/superpowers/reports/2026-04-19-structured-fail-closed-bootstrap-isolation-report.md`
|
|
|
|
Bootstrap target records were kept out of G3 and small-bucket recovery. No login recovery or bootstrap auto-recovery was implemented.
|
|
|
|
### Phase 5: Follow-Up Sweep and Coverage Delta
|
|
|
|
Completed.
|
|
|
|
Deliverables:
|
|
|
|
1. `tests/fixtures/generated_scene/structured_fail_closed_improvement_followup_2026-04-19.json`
|
|
2. `docs/superpowers/reports/2026-04-19-structured-fail-closed-improvement-coverage-delta-report.md`
|
|
|
|
Follow-up summary:
|
|
|
|
| Status | Baseline | Follow-up | Delta |
|
|
| --- | ---: | ---: | ---: |
|
|
| `auto-pass` | 48 | 48 | 0 |
|
|
| `fail-closed-known` | 48 | 47 | -1 |
|
|
| `adjudicated-valid-host-bridge` | 4 | 4 | 0 |
|
|
| `source-unreadable` | 2 | 3 | +1 |
|
|
|
|
The follow-up did not improve pass count and exposed one additional timeout:
|
|
|
|
`sweep-040-scene` / `嘉峪关日报`
|
|
|
|
## Validation
|
|
|
|
The implementation slice was validated with:
|
|
|
|
1. `cargo test --test scene_generator_test generator_blocks_incomplete_paginated_enrichment_workflow -- --nocapture`
|
|
2. `cargo test --test scene_generator_canonical_test -- --nocapture`
|
|
|
|
Both passed.
|
|
|
|
The fixed `102` scene follow-up sweep completed and wrote:
|
|
|
|
`tests/fixtures/generated_scene/structured_fail_closed_improvement_followup_2026-04-19.json`
|
|
|
|
## Closure Decision
|
|
|
|
This roadmap is closed.
|
|
|
|
It completed its required inventory, bounded implementation, small-bucket inspection, bootstrap isolation, follow-up sweep, and delta report.
|
|
|
|
The outcome is not a coverage increase. The outcome is better structured fail-closed evidence plus a measured follow-up baseline:
|
|
|
|
| Metric | Result |
|
|
| --- | --- |
|
|
| `auto-pass` coverage | unchanged at `48/102` |
|
|
| broad actionable count | `100 -> 99` |
|
|
| remaining structured fail-closed | `47` |
|
|
| remaining timeout | `3` |
|
|
|
|
## Next Inputs
|
|
|
|
The next work is outside this roadmap.
|
|
|
|
Highest-value inputs are:
|
|
|
|
1. bounded timeout regression diagnostic for `sweep-040-scene`
|
|
2. timeout diagnostic for the two persistent timeout records
|
|
3. a new bounded recovery roadmap for the remaining `34` `paginated_enrichment` structured fail-closed records
|
|
|
|
No next roadmap is started by this closure report.
