+# Stale PR Salvage Ledger
+
+This ledger records useful work recovered from stale, conflicted, or closed PRs.
+The rule is simple: queue cleanup closes stale PRs, but it does not discard
+useful work. Maintainers should inspect the closed diff, port compatible pieces
+on fresh branches, and credit the source PR.
+
+## Classification States
+
+| State | Meaning |
+| --- | --- |
+| Salvaged | Useful work was ported to current `main` through a maintainer PR. |
+| Already present | Current `main` already contained the useful work before salvage. |
+| Superseded | Current `main` solved the same problem differently. |
+| Skipped | The PR was accidental, too broad, unsafe, or too low-signal to port. |
+| Translator/manual review | Content may be useful, but needs human language/domain review before import. |
+
+## Salvaged Into Current Main
+
+| Source PR | Original contribution | Salvage result |
+| --- | --- | --- |
+| #1309 | Trading/community project material | Salvaged in #1761 as a neutral community-project README listing. |
+| #1322 | Vietnamese README translation | Salvaged in #1764 as `docs/vi-VN/README.md` plus selector updates. |
+| #1326 | Angular developer skill and rules | Salvaged in #1763 with current skill, rules, install wiring, and catalog updates. |
+| #1328 | Continuous-learning Windows UTF-8 stdout fix | Salvaged in #1761. |
+| #1329 | Plugin install detection hardening | Salvaged in #1761 through current harness audit detection support. |
+| #1334 | Windows desktop E2E skill | Salvaged in #1762 with install, package, and catalog wiring. |
+| #1352 | Qwen install target | Salvaged in #1738 through the current Qwen install target. |
+| #1413 | Network and homelab skills/agents | Salvaged through #1729, #1731, #1745, and #1778. |
+| #1429 | JoyCode install target | Salvaged in #1737 through the current JoyCode install target. |
+| #1467 | Scientific skills and OpenCode discovery work | Useful USPTO and gget pieces salvaged in #1740; stale generated claims were not copied. |
+| #1493 | SessionStart context scoping | Salvaged in #1774 with current hook semantics and tests. |
+| #1498 | PRD planning flow | Salvaged in #1777. |
+| #1504 | Statusline/context monitor hooks | Salvaged in #1776 with current hook manifest structure and tests. |
+| #1528/#1529/#1547 | Astraflow and UModelVerse provider support | Salvaged in #1775 with current provider wiring and defensive tool-call parsing. |
+| #1558 | `agentic-os` skill | Salvaged in #1772. |
+| #1559 | `error-handling` skill | Salvaged in #1772. |
+| #1566 | Agent architecture audit skill | Salvaged in #1772. |
+| #1578 | OpenCode file-probe hardening | Salvaged in #1773. |
+| #1674 | Production audit skill | Salvaged in #1732 after supply-chain/privacy review and rewrite. |
+| #1687 | zh-CN localization sync | Large safe subsets salvaged in #1746-#1752; remaining pieces require translator/manual review. |
+| #1694 | Portfolio curation | Useful focused curation updates salvaged in #1723 and #1724. |
+| #1695 | Russian README translation | Ported in #1722. |
+| #1697 | Saved LLM selector config | Salvaged as part of provider config/tool schema work in #1720. |
+| #1699 | Windows post-edit-format path guard | Ported in #1719. |
+| #1700 | Provider tool serialization | Ported in #1720. |
+| #1705/#1780 | Production UI motion system | Salvaged in #1772, #1781, and #1782 with examples fixed before merge. |
+| #1713 | Swift language support | Ported in #1721. |
+| #1715 | CI personal-path validator hardening | Ported through CI validator hardening in #1717. |
+| #1727 | MySQL patterns skill | Salvaged in #1733. |
+| #1757 | Machine-learning engineering workflow | Salvaged in #1758 and tuned in #1759. |
+
+## Already Present Or Superseded
+
+| Source PR | Disposition |
+| --- | --- |
+| #1306 | Hook bug workarounds already exist on `main` as `docs/hook-bug-workarounds.md`. |
+| #1318 | Gemini agent adaptation utility was already present on current `main`. |
+| #1323 | Hook config update was already present on current `main`. |
+| #1337 | Catalog count update was superseded by current catalog-count sync. |
+| #1682/#1701 | Strategic compact hook-path fixes were merged directly or superseded by current docs fixes. |
+| JARVIS #4/#5/#6 | Stale failing dependency-only PRs; future dependency state should be regenerated by Dependabot. |
+
+## Skipped
+
+| Source PR | Reason |
+| --- | --- |
+| #1308 | Stale zh-CN sync would rewind or delete too much current tree state; concrete selector-link fix was already present. |
+| #1320 | Package-manager removal conflicts with the current npm/pnpm/yarn/bun CI policy. |
+| #1341 | Very large low-signal generated change with no safe focused salvage unit. |
+| #1416/#1465 | Accidental fork-sync PRs with no focused contribution. |
+| #1475 | One-line Gemini CLI bridge idea was too stale and underspecified to port safely. |
+
+## Remaining Manual-Review Backlog
+
+Only the #1687 localization tail remains plausibly useful but unsafe to
+auto-port.
+
+Handling rule:
+
+1. Keep #1687 in translator/manual review.
+2. Split any future work by surface: agents, commands, top-level docs, release
+   and count surfaces, then skills.
+3. Do not import stale top-level docs that carry old version or catalog-count
+   facts.
+4. Do not reopen old PRs unless the original author returns with a current
+   rebase; maintainer-side salvage should happen on fresh branches with
+   attribution.
+
+## Future Cleanup Rule
+
+For every stale/conflicted PR cleanup batch:
+
+1. Close or comment on the PR based on the queue policy.
+2. Add the source PR to this ledger or a dated successor ledger.
+3. Classify it as salvaged, already present, superseded, skipped, or
+   translator/manual review.
+4. If useful, port a small compatible slice on a fresh maintainer branch.
+5. Credit the source PR and author in the maintainer PR body.
