docs(shard/0226Z): 52-stash survey + drop-tier classification (survey only)#4485
Conversation
… only, no drops) Picks up the 0202Z carry-forward at stash scope: vintage-stratified survey of all 52 stashes on the contested-root worktree. Drop-tier classification: - Tier A (clear drop): 11 stashes — empties, duplicates, worktree-agent orphans whose IDs no longer exist - Tier B (verify-then-drop): ~30 stashes on feat/* and main branches with cited PR # long-merged - Tier C (operator review): 5-6 substantive stashes with named topics worth operator inspection before drop Survey-only — no `git stash drop` operations. Operator decides. Composes with the substrate-drift discriminator at backlog-item-start-gate.md: this tick extends the discriminator's empirical-anchor chain to a third surface (stash scope, after row scope and orphaned-branch scope). Authored via isolated worktree per zeta-expected-branch.md race-window- caveat. Stash list read from contested root (read-only) before worktree-add. Pre-empt at brief-ack #5 per holding-without-named-dependency-is-standing- by-failure.md post-arc-completion empirical anchor: bounded genuinely- new substrate work.

Pull request overview
Adds a new hygiene-history tick shard (0226Z) documenting a survey of the contested-root worktree’s 52 git stashes, stratified by age and classified into drop tiers (A/B/C), as evidence for an operator-led cleanup. The shard also frames the stash triage as an extension of the existing substrate-drift discriminator (row-scope + orphaned-branch-scope) to a third surface (stash-scope).
Changes:
- Add a 52-stash vintage stratification table and Tier A/B/C classification with per-stash notes.
- Document how the existing substrate-drift discriminator composes at stash scope, including verification bullets and cross-links to related rules/PRs.

stash@{21} is marked Tier A ("almost-certainly droppable") even though this same row says it has 5 files / 287+136 changes and is likely the actual content-bearing copy. Classifying a substantive stash as clear-drop creates a real risk of irreversible work loss if Tier A entries are dropped in bulk without inspection.

The Tier D accounting says Tier B is ~30 with ~5-6 uncategorized, but the Tier B/C tables above already enumerate all remaining stash IDs (35 in B and 6 in C), which fully accounts for 52 with no uncategorized remainder. This mismatch makes the survey internally inconsistent and can mislead operator follow-up.

The verify bullet asserts stash groups are "byte-identical," but earlier rows record materially different diff sizes for those same stashes (for example stash@{20} empty vs stash@{21} with 5-file changes, and stash@{41}/{42}/{44} with different line counts). This overstates validation evidence and can justify incorrect drops.

… surface (#4490) * docs(shard/0249Z): 318 working-tree mods categorical triage — discriminator's 4th surface Picks up the 0202Z carry-forward at working-tree-mods scope: categorical triage of 318 untracked-or-modified files on contested root. Categorical breakdown of 283 untracked files: - 146 (54%) Tier A clear-drop: already byte-identical on main - ~11 Tier B local-machine artifacts (not factory substrate) - 126 (46%) Tier C operator-review: missing from main * 109 tick shards from 2026-05-18 (interrupted-session history) * 12 PR-discussions (never made it to substrate) * 3 research docs + 1 backlog row + 1 memory file * 1 .claude/rules byte-differs from main (tonal-momentum...) The substrate-drift discriminator now anchors at 4 surfaces: 1. Row scope (backlog-item-start-gate.md step 0) 2. Orphaned-branch scope (PR #4477 + #4478 + #4482) 3. Stash scope (PR #4485 — 0226Z) 4. Working-tree-mods scope (THIS shard — 0249Z) After 4 surfaces, the 0059Z carry-forward ("311 mods + 52 stashes") is fully surveyed; remaining work is operator-decision on the 126 missing-from-main files. Survey only. No git add / git clean / file-deletion operations. Pre-empt at brief-ack #5 per holding-without-named-dependency rule post-arc-completion empirical anchor.

Row scope is the backlog-item-start-gate.md step-0 surface, not the orphaned-commit verification surface. Verified-true finding; the wording is corrected to match the actual discriminator surface PR #4478 anchors. The 3 other threads on this PR were already outdated by the markdownlint fix in commit 1cbf8fc.

Summary
Picks up the PR #4478 (0202Z) carry-forward at stash scope: vintage-stratified survey of all 52 stashes on the contested-root worktree with drop-tier classification.
Drop-tier classification
feat/*andmainbranches with cited PR # long-mergedRoughly ~80% of stashes are clear or near-clear drop candidates.
Substrate-drift discriminator extends to third surface
Extends the
backlog-item-start-gate.mdsubstrate-drift discriminator from row scope (step 0) and orphaned-branch scope (PR #4477 + PR #4482) to a third surface — stash scope. Each surface confirms the cheap heuristic operates reliably across substrate-locations.Operational stance
Survey only. No
git stash dropoperations performed this tick. Operator decides actual drops with this classification as evidence.Note — PR-create deferred via pure-git tier
Branch was pushed at 0226Z but
gh pr createwas blocked by GraphQL exhaustion (0/5000). Perrefresh-world-model-poll-pr-gate.mdPure-git tier discipline, substrate ships via branch push; PR creation defers to post-reset tick. This PR is the post-reset open (rate reset at ~0241Z; PR opened ~14 min after the branch landed via pure-git).🤖 Generated with Claude Code
