+# V1R4C4 SR-01: Gitea Branch Sync Fix
+
+Status: started
+
+Priority: P0
+
+Risk: medium
+
+Baseline dependency: V1R4C3
+
+## Decision
+
+Start V1R4C4 with SR-01 only.
+
+SR-04 Portal AIOS Integration Merge remains deferred and is not part of this execution scope.
+
+## Background
+
+V1R4C3 completed the immediate branch_sync mitigation by changing branch synchronization to use `git ls-remote` instead of depending on the Gitea branch API pagination path.
+
+That mitigation avoids the user-visible failure path, but it does not fully certify or eliminate the root reliability issue:
+
+```text
+bare repository refs
+        !=
+Gitea branch metadata / DB index
+        !=
+Gitea branch API visible state
+```
+
+SR-01 exists to validate and fix the root problem category: Gitea branch metadata/index drift from the bare repository state.
+
+## Scope
+
+SR-01 includes:
+
+1. Confirm current branch_sync no longer depends on Gitea API pagination.
+2. Validate that Gitea DB branch metadata is consistent with bare repository refs.
+3. Add or activate consistency verification around branch metadata drift.
+4. Ensure autonomous operations do not continue mutating state when drift is detected.
+5. Produce a repeatable acceptance test for future incidents.
+
+SR-01 excludes:
+
+- Portal AIOS Integration Merge.
+- Search Gateway real provider binding.
+- Broad P1 capability merges.
+- Bulk patch merge or branch deletion.
+
+## Required Checks
+
+### Branch sync path
+
+Verify branch_sync source of truth:
+
+```text
+git ls-remote / bare repository refs
+```
+
+The Gitea branch API must not be the mandatory source of truth for synchronization.
+
+### Gitea consistency path
+
+Verify equality between:
+
+```text
+bare repository refs count
+Gitea branch live metadata count
+Gitea branch API paginated visible count
+```
+
+Any mismatch must be treated as reliability drift.
+
+### Safe-mode behavior
+
+When drift is detected:
+
+1. Stop autonomous mutations.
+2. Preserve read-only diagnostics.
+3. Emit safe-mode marker.
+4. Require controlled recovery before mutation resumes.
+
+## Acceptance Criteria
+
+SR-01 is complete when all of the following are true:
+
+1. branch_sync continues to work without Gitea branch API pagination dependency.
+2. Gitea branch metadata drift can be detected deterministically.
+3. Drift causes autonomous safe mode instead of continued mutation.
+4. Recovery procedure includes minimal repair, not default restart.
+5. Runtime acceptance passes:
+
+```text
+getRuntimeStatus
+    ->
+getBaseline
+    ->
+createBranch
+    ->
+createPatch
+```
+
+Expected results:
+
+- runtime status is active;
+- baseline reads V1R4C3 or later;
+- createBranch returns commit/rev/sync status;
+- createPatch returns commit/rev/sync status.
+
+## Execution Order
+
+1. Open SR-01 patch branch.
+2. Review V1R4C3 branch_sync behavior.
+3. Integrate Gitea branch consistency sentinel and safe-mode gate.
+4. Run runtime acceptance.
+5. If clean, prepare V1R4C4 reliability baseline proposal.
+
+## Follow-on Gates
+
+SR-02 Watcher State Cleanup may start after SR-01 acceptance is green.
+
+SR-03 Search Gateway Real Provider Binding may start after SR-01 confirms GitOps/Gitea reliability is stable enough for non-P0 work.
+
+SR-04 Portal AIOS Integration Merge remains deferred pending explicit approval.
+
+## Safety Rules
+
+- Do not bulk merge old patches.
+- Do not delete remote branches during SR-01 unless the branch consistency sentinel is already deployed and healthy.
+- Do not restart Gitea unless process-level failure is proven.
+- Do not modify Gitea DB without backup and owner/admin approval.

-# Search Gateway Resilience
-
-## Positioning
-
-SR-02 is a generic Search Gateway capability improvement. It is not tied to education, exams, geography, policy, product search, or any single content vertical.
-
-The goal is to convert Search Gateway from single-shot retrieval into an evidence-first retrieval pipeline:
-
-```text
-query normalization
-→ source planning
-→ official/direct adapters
-→ provider fallback
-→ extraction
-→ evidence cache
-→ confidence scoring
-→ failure diagnosis
-→ human evidence request when needed
-```
-
-## Generic capabilities
-
-### 1. Multi-source fallback
-
-Search Gateway should not fail just because one provider is blocked, truncated, rate-limited, or dynamically rendered.
-
-Default fallback chain:
-
-```text
-direct_official_adapter
-→ official_site_search
-→ structured_api_or_feed
-→ search_engine_provider
-→ authoritative_mirror_or_media
-→ cached_evidence
-→ user_supplied_evidence_request
-```
-
-### 2. Source tiering
-
-Every source is classified before being trusted:
-
-```text
-OFFICIAL_PRIMARY
-OFFICIAL_SECONDARY
-AUTHORITATIVE_MEDIA
-SPECIALIZED_DATABASE
-GENERAL_WEB
-USER_SUPPLIED_EVIDENCE
-```
-
-The same tiering model works for public policy, software documentation, finance data, product specs, standards, academic sources, sports, travel, and user-supplied documents.
-
-### 3. Failure diagnosis
-
-Search failures must be structured, not vague.
-
-Examples:
-
-```text
-SEARCH_PROVIDER_TIMEOUT
-SEARCH_PROVIDER_CAPTCHA
-SEARCH_RESULT_TRUNCATED
-SOURCE_BLOCKED_BY_CDN
-SOURCE_DYNAMIC_PAGE_UNREADABLE
-OFFICIAL_SOURCE_FOUND_BUT_EXTRACTION_FAILED
-SOURCE_CONFLICT_NEEDS_REVIEW
-EVIDENCE_CACHE_STALE
-HUMAN_EVIDENCE_REQUIRED
-```
-
-### 4. Evidence cache
-
-A successful retrieval should leave structured evidence behind:
-
-```yaml
-evidence_id: ev-...
-normalized_query: ...
-source_tier: OFFICIAL_PRIMARY
-publisher: ...
-url: ...
-extracted_at: ...
-published_at: ...
-answer_fields: {...}
-confidence: high
-```
-
-Cache entries must carry staleness rules by topic type. Time-sensitive information should expire faster than static references.
-
-### 5. Confidence scoring
-
-Search Gateway should return both the answer and confidence metadata:
-
-```json
-{
-  "answer": {},
-  "confidence": 0.95,
-  "confidence_level": "high",
-  "sources": [],
-  "fallback_used": true,
-  "failure_codes": [],
-  "evidence_ids": []
-}
-```
-
-### 6. Human evidence intake
-
-When automated retrieval is blocked, Search Gateway should ask for a screenshot, URL, PDF, or pasted text and ingest it as `USER_SUPPLIED_EVIDENCE`, rather than silently failing.
-
-## Non-goals
-
-- No vertical-specific hardcoding.
-- No CAPTCHA bypass.
-- No access-control bypass.
-- No scraping of protected/private content.
-- No treating search snippets as authoritative without source classification.
-
-## Acceptance
-
-SR-02 is accepted when:
-
-```text
-AIOS_SEARCH_GATEWAY_MULTI_SOURCE_READY
-AIOS_SEARCH_GATEWAY_FAILURE_DIAGNOSIS_READY
-AIOS_SEARCH_GATEWAY_EVIDENCE_CACHE_READY
-AIOS_SEARCH_GATEWAY_CONFIDENCE_SCORING_READY
-AIOS_SEARCH_GATEWAY_GENERIC_RESILIENCE_READY
-```
