docs: add open PR reconciliation handoff

[jwalin-shah]

Summary

• Added a docs-only reconciliation handoff for the current upstream OpenHuman PR queue.
• Identified stale/conflicting PRs, hot-file conflict clusters, validation gates, and the next safe implementation slice.
• Incorporated Gemini secondary-review feedback: no batch rebases, refresh PR metadata/body before repair, audit Files Reviewed #1462 lockfile churn, and treat fix(observability): classify backend 4xx as BackendUserError (OPENHUMAN-TAURI-BC) #1676 as likely observability base.

Problem

The upstream PR queue has many simultaneous blocked/conflicting branches, making new implementation work risky without a durable handoff.

Solution

Captured a timestamped queue snapshot and reconciliation order in docs/agent-workflows/open-pr-reconciliation-2026-05-13.md.

Submission Checklist

• Tests added or updated (happy path + at least one failure / edge case) per Testing Strategy - N/A: docs-only reconciliation handoff; validated with parser/assertion commands below.
• Diff coverage >= 80% - N/A: docs-only change; no product code changed.
• Coverage matrix updated - N/A: no product feature added, removed, renamed, or changed.
• All affected feature IDs from the matrix are listed in the PR description under ## Related - N/A: no affected feature IDs.
• No new external network dependencies introduced (mock backend used per Testing Strategy) - N/A: docs-only change.
• Manual smoke checklist updated if this touches release-cut surfaces (docs/RELEASE-MANUAL-SMOKE.md) - N/A: no release-cut surface changed.
• Linked issue closed via Closes #NNN in the ## Related section - N/A: no issue supplied for this reconciliation slice.

Impact

Docs-only; no runtime, migration, security, or performance impact.

Related

• Closes: N/A
• Follow-up PR(s)/TODOs: audit and canonicalize Files Reviewed #1462, then reconcile the observability PR stack.

📝 Walkthrough

Walkthrough

Adds a new process document that captures the current PR queue state, identifies shared conflict surfaces across PRs, prescribes validation gates and a safe reconciliation order, and specifies concrete CLI commands and validation steps for the next implementation work focused on PR #1462.

Changes

PR Reconciliation Process Handoff

Layer / File(s)	Summary
Queue Status and Conflict Assessment docs/agent-workflows/open-pr-reconciliation-2026-05-13.md (lines 1–67)	Current queue snapshot with PR counts, merge-state distribution, and a full table of open/draft PRs listing file impact and notes. Conflict Clusters section identifies high-overlap surfaces and guides rebasing/merging strategy for hotspots.
Validation Gates and Reconciliation Playbook docs/agent-workflows/open-pr-reconciliation-2026-05-13.md (lines 68–151)	Validation gates for checklist, formatting, typecheck, focused tests, and coverage. Recommended reconciliation order for closing stale PRs, consolidating observability stack, and reconciling credentials-lock PRs. Defines the next safe implementation slice focused on PR #1462 with exact GitHub CLI commands to refresh metadata, assess unique work, and decide whether to close or create a narrower branch.

Handoff update: the full GitHub CI matrix is now green. Direct merge failed because base branch policy prohibits this credential from merging; enabling auto-merge also failed with GraphQL: jwalin-shah does not have the correct permissions to execute EnablePullRequestAutoMerge. Required next action: maintainer with merge/auto-merge permissions should merge this PR if satisfied.
