Audit record written with `user_choice` and `recommended` both set to the full name `HOLD SCOPE`, `auto_decided: true`. Confirmed written (`QLOG_OK`).\n- Working plan with the pre-review audit, 0A\u20130C evidence, landscape check, and decision ledger (R1 mode approved, R2 sort-key semantics pending) saved to `.claude/plans/keep-this-draft-plan-virtual-moonbeam.md`. `PLAN.md` untouched.\n- Skill-end recorded with `outcome=abort` since the workflow intentionally stopped before 0G/0I/review sections; that is the honest label for an incomplete run, not an error.\n\nConcerns / what I skipped:\n- `routing-injection` setup block deferred (you own setup; plan mode forbids the CLAUDE.md edit and commit). It will re-fire next healthy run.\n- Office Hours not offered, per your instruction.\n- No `GSTACK REVIEW REPORT` exists, so the Exit Plan Mode gate is **Blocked** by design and I did not call ExitPlanMode. Remaining route for the later review: 0G \u2192 0I \u2192 `sections/review-sections.md`, carrying ledger rows R1 and R2.\n- One durable learning logged (Conductor + plan mode vs. onboarding blocks that need repo commits).\n\nStopping here for your next message.",

When asked to record directories, most archive formats will read their content in the order returned by the filesystem which is likely to be different on every run.\n\nThis bites language-level APIs too, not just shell tools. A recent bug report notes that os.walk yields subdirectories in readdir order, which differs between two copies of the same tree. The generated unordered_map initializer then lists system/languages and system/workflows in a different order across builds and the compiled binary differs. Sorting dirs in place fixes the traversal order. Debian's reproducibility tracker categorizes this as its own issue class: fileordering: build output varies with readdir() order. Historical examples include GNU Libtool prior to 74c8993c (first included in version 2.2.7b) did not sort the find output. It appears that many packages are bootstrapped with a version prior to this. Also, GNU Make used to sort the output of the wildcard function until version 3.82.\n\n## Pitfall 2: Sorting, but with a locale-dependent collation\n\nAdding a `sort` step isn't enough if the locale is uncontrolled. When sorting inputs, one must ensure that the sorting order is not affected by the system locale settings. Some locales will not distinguish between uppercase and lowercase characters. Makefiles that invoke sort without LC_ALL=C produce locale-dependent ordering.\n\nThe concrete difference is easy to demonstrate: C/POSIX Locale: Uses ASCII values for sorting (e.g., 'A' < 'B' < 'a' < 'b'). UTF-8 Locales (e.g., en_US.UTF-8): Use Unicode Collation Algorithm (UCA), which is language-aware (e.g., case-insensitive sorting, accent handling). One user observed that LC_COLLATE=en_US.UTF-8 gives case-insensitive sort (upper- and lowercase mixed), while LC_CTYPE=C (that is what we are all used to) gives case-sensitive sort, i.e. the uppercase filenames are on top of the ls listing. Locale collation can also be surprising with punctuation: The sorting characteristics of C are strict ASCII order, spaces significant. The characteristics of en_* are dictionary order, more spaces sort after fewer spaces. And one report found that en_US asserts '/root/' < '/root0' but '/root/t' > '/root0' \u2014 which is a nasty trap for path sorting specifically.\n\nThe practical upshot: machines normally working in the 'C' locale produce seriously different directory listings than those in an Unicode locale, one cannot compare these quickly with a glance. Given in addition the possible alterability of (inter)national sorting conventions, it might be best to leave LC_COLLATE=C and only change this for applications which do concern.\n\n## Recommended approaches\n\n**Shell / archive pipelines:** With version 1.28, GNU Tar has gained the --sort=name option which will sort filenames in a locale independent manner: # Works with GNU Tar 1.28 $ tar --sort=name -cf product.tar build \u00b7 For older versions or other archive formats, it is possible to use find and sort to achieve the same effect: $ find build -print0 | LC_ALL=C sort -z | tar --no-recursion --null -T - -cf product.tar \u00b7 Care must be taken to ensure that sort is called in the context of the C locale to avoid any surprises related to collation order.\n\n**If you specifically want case-insensitive output:** don't rely on the locale to give it to you. Instead, do a byte-wise (C-locale) sort on an explicitly case-folded key (e.g., lowercase the name in your own code, or use `sort -f` with `LC_ALL=C`), and use the original byte string as a tiebreaker so that `Foo` and `foo` always land in the same relative order. Also note that C-locale byte ordering handles non-ASCII poorly for human readability \u2014 In C locale, multi-byte characters (like '\u00e9' in UTF-8) are sorted by raw byte values \u2014 but that's a feature for determinism: it is stable across machines, which locale-aware collation is not (glibc, musl, macOS, and ICU all differ).\n\n**Testing:** The Reproducible Builds project built disorderfs, a FUSE filesystem overlay that deliberately shuffles directory entries to expose ordering bugs during testing. It also maintains reprotest, which builds packages under deliberately varied conditions (different timezones, user IDs, locales, hostnames, file ordering) to flush out hidden assumptions.\n\n## Related nondeterminism sources to watch for\n\nBeyond directory order, broader surveys list Embedded timestamps (DATE, TIME), build-paths, and C macro expansions. Filesystem or archive ordering (unsorted glob, POSIX readdir). User, hostname, kernel, or locale-specific data. Random numbers or race-dependent output order in parallelized build steps. In particular, Build systems that dispatch jobs to a thread pool and aggregate results in completion order will interleave output differently on each run. So if your CLI listing is built concurrently, collect results first and sort once at the end rather than emitting as they arrive.\n\n**Summary rule of thumb:** never emit or hash anything in readdir/glob/os.walk order; always sort explicitly; sort using a locale-independent (bytewise) comparison on a key you control \u2014 case-folded if you want case-insensitivity \u2014 with a deterministic tiebreaker; and test under disorderfs/reprotest-style variation.\n\n\nREMINDER: You MUST include the sources above in your response to the user using markdown hyperlinks.",

Source of the draft: `PLAN.md` in the repo\nroot (read-only in plan mode; this file is the host active plan).\n\n## Context\n\nUsers diff skill listings in scripts and reviews. Today the listing path emits\nregistered skill names in whatever order the registry produced them, which\nfollows directory enumeration order and so differs between filesystems and\nmachines. The change sorts names deterministically before rendering, and\nnothing else: membership, aliases, metadata and the text/JSON output formats\nstay byte-identical apart from order.\n\n## Draft plan under review (verbatim from PLAN.md)\n\n> Users compare skill listings in scripts and reviews. Make the existing listing\n> path sort registered skill names deterministically before rendering them.\n> Keep skill membership, aliases, metadata and text/JSON output formats unchanged.\n> Cover mixed-case names and differing directory enumeration order with tests.\n\nStated limits (recorded, unchanged):\n- Scope: the existing listing path only. No new commands, flags or formats.\n- Invariants: membership, aliases, metadata, text and JSON output formats unchanged.\n- Required tests: mixed-case names; differing directory enumeration order.\n- This invocation: review-mode decision only. Office Hours and setup handled\n  separately by the user. Substantive review runs later.\n\n## Pre-review system audit (2026-09-17)\n\n- Repo state: single commit `dfc3039 Seed review plan`; files `CLAUDE.md`, `PLAN.md`.\n  No remote, no stash, no TODOS.md, no FIXME/TODO markers, no architecture docs.\n- Design doc: none. Handoff note: none. Office Hours not offered (user deferred it).\n- Prior learnings: 0 (cross-project learnings configured off). Brain digests cold.\n- Retrospective check: no prior reviews, refactors or reverts on this repo.\n- Frontend/UI scope: none. DESIGN_SCOPE = no (CLI text/JSON output only).\n- Landscape check (WebSearch fallback; Aside not installed):\n  - Layer 1: never emit in readdir/glob order; sort explicitly on a key you\n    control; use locale-independent comparison; for case-insensitive order,\n    sort on a case-folded key with the raw name as tiebreak; test under\n    shuffled enumeration (disorderfs/reprotest pattern).\n  - Layer 2: reproducible-builds.org lists `fileordering` as its own bug class;\n    `os.walk`/readdir order bugs recur across ecosystems; locale-aware collation\n    (glibc, musl, macOS, ICU) disagrees across machines and is itself a\n    nondeterminism source.\n  - Layer 3: the draft says \"deterministically\" but not which order. Pure\n    byte order puts `Zeta` before `alpha`; a case-folded key reads naturally\n    for humans but needs a tiebreak for `Foo` vs `foo`. This is a pending\n    implementation choice, not a scope change. Left pending for the review.\n- Deliverable count (estimate, target codebase not in this repo): 2 files\n  changed (listing/render module edit; test file add or edit). No new\n  classes or services.\n\n## Step 0A. Premise challenge\n\n1. Right problem: yes. Unstable order breaks `diff`, snapshot tests and\n   review-by-eye. Sorting at render is the smallest correct fix.\n2. Outcome: identical listing output for identical registries on any machine.\n   The plan reaches this directly; no proxy.\n3. Do nothing: scripted comparisons keep producing false diffs. Pain is real\n   and recurring, not hypothetical.\n\n## Step 0B. Existing code leverage\n\n- Sub-problem \"order names\": standard library sort with an explicit key.\n  No new dependency, no new abstraction.\n- Sub-problem \"keep output formats unchanged\": reuse the existing text and JSON\n  renderers as-is; sort the name sequence they already consume.\n- Sub-problem \"differing enumeration order\": tests feed the registry a\n  shuffled/reversed name set rather than depending on the filesystem.\n- Nothing is rebuilt; this is a one-point insertion on the existing path.\n\n## Step 0C. Dream state mapping\n\n```\n  CURRENT STATE                    THIS PLAN                       12-MONTH IDEAL\n  listing order follows    --->    sort names once at the   --->   every user-facing\n  directory enumeration;           existing render point;          listing/enumeration\n  differs per machine;             invariants pinned by             is order-stable and\n  scripts see false diffs          tests                            snapshot-tested\n```\n\nThe plan moves toward the ideal along the straight line.\n\n## Step 0D. Alternatives\n\nNo new approach decision was needed. The draft fixes one approach (sort at the\nexisting listing path), the invariants are explicit, and the audit found no\ncontradiction, changed assumption or user instruction that would reopen it.\nThe only open item (sort key: byte order vs case-folded with tiebreak) is an\nimplementation choice inside the approved approach; it stays pending for the\nsubstantive review, per the user's instruction to decide mode only.\n\n## Decision ledger\n\n| ID and owner | Contract and evidence | Current | Proposed | Status | Exact approval and scope |\n|---|---|---|---|---|---|\n| R1 (user) | Review mode for this draft. Evidence: PLAN.md lines 8-13 (\"No review mode has been selected\"); draft goal is correcting existing behavior in an existing path (fix/refactor); ~2 planned changed files (estimate). | none | HOLD SCOPE (recommended per 0E step 2) | approved | `plan-ceo-review-mode` preference check exited 0 with `AUTO_DECIDE`; auto-selected HOLD SCOPE per 0E step 3. User may change with /plan-tune or by asking. |\n| R2 (implementer) | Sort key semantics (byte order vs case-folded key + raw-name tiebreak). Evidence: draft requires mixed-case test coverage but names no order. | unspecified | pending | unresolved | Not asked this invocation; user requested mode decision only. |\n\n## Step 0E. Mode selection and provenance\n\n- Explicit user choice: none (\"No review mode has been selected\").\n- Recommendation (0E step 2): file count ~2 (below the >15 REDUCTION\n  threshold); goal is correcting existing behavior in an existing system\n  (fix/refactor) \u2192 HOLD SCOPE.\n- Resolution (0E step 3): `QUESTION_TUNING: true`; ran\n  `gstack-question-preference --check plan-ceo-review-mode --summary-stdin`;\n  result `AUTO_DECIDE`, exit 0. Selected the recommendation automatically.\n- Selected mode: **HOLD SCOPE**.\n- Provenance route: successful preference check. Question log written with\n  `user_choice: \"HOLD SCOPE\"`, `recommended: \"HOLD SCOPE\"`, `auto_decided: true`.\n- Setup deferred: `routing-injection` instruction block (CLAUDE.md skill routing)\n  not acted on; user handles setup separately and plan mode forbids the\n  CLAUDE.md edit and commit. Its marker gate will re-fire next healthy run.\n\n## Remaining route (not run this invocation)\n\nHOLD SCOPE route: 0G (complexity check, minimum changes, keep invariants) \u2192 0I\n(temporal interrogation) \u2192 `sections/review-sections.md` (Sections 1\u201311, required\noutputs, GSTACK REVIEW REPORT). The user will run the substantive review later.\nCarry ledger rows R1 and R2 into it.\n\n## NOT in scope\n\nNothing deferred or cut yet. Ledger row R2 is pending, not excluded.\n"
