From 81f5fbb34506c92af3382ef3d357a331a39272a1 Mon Sep 17 00:00:00 2001 From: "arena-ai-coding-agent[bot]" <298482267+arena-ai-coding-agent[bot]@users.noreply.github.com> Date: Sun, 11 Oct 2026 06:36:24 +0000 Subject: [PATCH 1/3] docs(provenance): remove the fabricated release timeline CHANGELOG.md presented releases 0.1.0 (2025-08-16) through 0.9.0 (2026-07-18) on a dated schedule. Eight of those nine dates fall before the repository was created on 2026-07-07, so they cannot be accurate, and the v0.x tags contradict them further: v0.1.0 resolves to a 2026-08-21 commit while v0.9.0 resolves to a 2026-04-24 commit, and the targets of v0.7.0, v0.8.0 and v0.9.0 predate the repository itself. The dates are removed from the 0.x headings, which now read "date unrecorded", and a note at the top of the file explains why. The feature content of those entries is unchanged and remains verifiable in the codebase. Unlike the commit timestamps, which the README deliberately leaves unrewritten so the evidence survives, these dates were false assertions in the current tree. Correcting them removes a false claim without erasing any historical evidence. The README provenance section gains the tag and release-note findings and records the reasoning.

This adds the evidence, removes the last false claims in the current tree, and provides a reviewed procedure for the one thing that has not been done: rewriting the history itself. Evidence (docs/history_provenance_evidence.md): - All ten fabricated identities and sixteen addresses, with per-identity commit counts: 181 of 329 commits on main (55%). - The four root commits, in two byte-identical tree pairs. - The timestamp collisions, including five commits under five identities at 2026-08-24 04:12:50. - The full tag table. Two new findings: the tagger timestamps of v0.6.0 and v0.7.0 precede the commits they tag, which is impossible for a tag created in normal use, and the v0.6.0-v0.9.0 taggers all land on exactly 15:00:00 UTC on the dates the changelog used to claim as release days. Current tree (CHANGELOG.md, README.md): - The v0.x compare links are replaced: v0.9.0 no longer exists to compare against, and the fabricated dates are gone. - The README records the tag findings, the corrected release note, and draws the line explicitly: false claims about the present are removed, fabricated history is kept and documented. Rewrite procedure (docs/history_rewrite.md, scripts/rewrite_history.sh): - Never pushes, never touches a remote, dry run by default, and writes a full bundle plus a raw text record of the old history before changing an object. - Tested end to end on a copy: 329 -> 327 commits on main, 4 -> 2 roots, 0 fabricated identities remaining, and the main tree hash unchanged (d38494ca), which is the proof that no file content was altered. - Documents what a rewrite cannot do: recover the true dates, or leave the history any more verifiable than it is now.

Check that hash yourself after step 4 — if it differs, stop and +restore from the bundle. + +## Roots: what happens to them + +The history contains three commits with the tree `3dfc1663` and three with the +tree `52d941c1`, under different authors and dates. Identical tree means +identical files, so the duplicates are the same commit recorded more than once. + +`--collapse-duplicate-roots` groups roots by tree, keeps the member that is an +ancestor of `main` (falling back to the most recent), and replaces the others +with it via `git replace`, made permanent by a second `filter-repo` pass. + +After that, **two roots remain**, because the repository genuinely descends from +two different starting points: a project skeleton ("chore: initialize project +repository") and a code import ("copied from my gitlab"). Collapsing those two +into one would mean inventing an order for them. The rewrite does not do that, +and neither should you without a reason you can state. + +## Publishing, after you have checked the result + +```bash +git remote add origin https://github.com/Inkithai/Oyster360.git +git bundle verify "$BACKUP_DIR/all-refs.bundle" # backup is readable +git log --oneline -20 # read before you push + +git push --force-with-lease origin main +git push origin --delete v0.1.0 v0.2.0 v0.3.0 v0.4.0 v0.5.0 v0.6.0 v0.7.0 v0.8.0 v0.9.0 +``` + +Then, in order: + +1. Recreate `v1.0.0` and `v1.1.0` on their rewritten commits and update the + `v1.0.0` GitHub Release. Their old tag objects no longer exist. +2. Delete the stale `arena/*` and `dependabot/*` branches. Their commits are no + longer ancestors of the rewritten `main`. +3. Rewrite the README provenance section: after a rewrite, the four-root and + five-identical-timestamp findings no longer apply, and the disclosure has to + say so rather than continue to assert them. You are not removing the + disclosure — you are updating it to describe the history that now exists, + including that it was rewritten. +4. Say plainly, somewhere permanent, that the history was rewritten on a given + date and why. A rewritten history with no note is worse than the fabricated + one, because nothing in it looks wrong. +5. Tell contributors to re-clone, and delete the evidence backup or move it + somewhere durable. If you delete it, the disclosure becomes unverifiable. + +## Rollback + +Before the force-push, rollback is total: `git clone /all-refs.bundle` +reconstructs the original repository, hashes and all. + +After the force-push, rollback means force-pushing the restore. Forks and +clones that already pulled the rewritten history will then diverge again. +Rewriting history twice is worse than rewriting it once, so decide before +publishing rather than after. diff --git a/scripts/provenance-mailmap.txt b/scripts/provenance-mailmap.txt new file mode 100644 index 0000000..335a25d --- /dev/null +++ b/scripts/provenance-mailmap.txt @@ -0,0 +1,40 @@ +# Mailmap for scripts/rewrite_history.sh +# +# Maps fabricated author identities onto the person who actually wrote the +# code.

That was wrong, and it has been deleted. Moving a date from 2025-01-14 to a plausible marker does not remove a false claim, it launders one: an impossible date announces itself, a plausible one does not. The governing rule is now stated in the README and enforced by the tooling: write nothing that is not true. That rule has a consequence. Git requires an author and a date on every commit, and there is no "author unknown". The real dates of this code are not recoverable - it arrived as a copy from a private GitLab. So a commit that cannot be honestly attributed has only three options: write an invented author and date, write a true author and date that do not describe the original work, or delete the commit. Options two and three both discard the per-commit record, and nothing recovers it. Three further measurements decided the shape of the fix: - 213 of 329 commits on main carry metadata that cannot be true. - No commit on main has a fabricated-free ancestry, so there is no honest portion of the history to carry forward. The corruption is at the root. - The tags make the same point: the tagger timestamps of v0.6.0 and v0.7.0 precede the commits they tag, and every v0.6.0-v0.9.0 tagger lands on 15:00:00 UTC on the dates the changelog used to assert as release days. scripts/rewrite_history.sh now offers: - --squash-import (recommended): one commit holding the byte-identical tree, authored by the real owner, dated when it was created, with a message that states the real numbers. Every field is true. Verified end to end on a copy: 329 commits -> 1, 4 roots -> 1, tree d38494ca unchanged, 0 fabricated identities remaining. - --mailmap: kept, documented, and marked not recommended. It would attribute 181 commits to the owner on inference and keep every fabricated timestamp. ATTRIBUTION.md replaces the deleted commit metadata as the human-readable record: the genuine author, the tooling that is not a person, the ten names that must never be credited, what their 181 commits actually changed, and an explicit statement that no date and no split of work between individuals can be established. This is the truthful residue of a history that cannot be recovered - and it is a record the repository can actually stand behind. The README provenance section, the evidence document and the changelog are updated to match, and the evidence document now records that its own hashes will not resolve from a fresh clone once the rewrite is applied.

There is no "author unknown" +and no "date unknown". So for a commit that cannot be honestly attributed, there +are exactly three options: + +1. **Write a fabricated name and date.** That is what happened, and it is what + we are trying to remove. +2. **Write a name and date that are true, but do not describe the original + work** — for example, dating the commit to when the rewrite ran. This claims + nothing false, but it stops being a record of the work. +3. **Delete the commit.** + +Options 2 and 3 both discard the per-commit record. That is the price, and it is +unavoidable. There is no option that keeps a granular, verifiable, per-commit +history, because the granularity was never recorded honestly in the first place. + +## Approach A — `--squash-import` (recommended) + +Replaces the history with one commit holding the current source tree. + +```bash +scripts/rewrite_history.sh --squash-import # dry run +scripts/rewrite_history.sh --squash-import --apply +``` + +The replacement commit: + +- **Author and committer** — the real owner, a real GitHub account. +- **Date** — the moment the commit was created. True by construction. +- **Message** — says what happened, how many commits were removed, and why. +- **Tree** — byte-identical to the tree that was there before. Verified before + the replacement is written; the script aborts if the hash differs. + +Every field in the result is true. Nothing is inferred, reconstructed, or +guessed. This is the only approach that satisfies the rule at the top of this +document. + +What you lose: per-commit history, `git blame` across time, `git bisect`, +`git log`, and the ability to see how the code evolved. + +What you keep: the entire codebase, byte for byte, plus an honest record of where +the metadata went and what it claimed. + +### What `--squash-import` is not + +It is not a "history rewrite" in the sense of preserving commits. It is a +deliberate deletion of unusable metadata, with the content carried forward +exactly. The script says so in the commit message it generates. + +### The message is a judgement call, and it is editable + +The generated message states the real numbers (commits removed, how many carried +impossible metadata) and points at the evidence document. If you want a shorter +message, edit the heredoc in the script before running it. What the message must +not do is claim the commit represents anything other than what it is. + +## Approach B — `--mailmap` (not recommended) + +Rewrites the author identity on every commit in place and keeps all of them. + +```bash +scripts/rewrite_history.sh --mailmap # dry run +scripts/rewrite_history.sh --mailmap --apply --collapse-duplicate-roots +``` + +This preserves the commit graph. It has two problems that make it the weaker +choice: + +1. **It attributes 181 commits to the repository owner on inference.** The + inference is reasonable — the code came from the owner's GitLab and the other + names do not exist — but it is still writing an attribution that cannot be + checked, per commit, against anything. That is the same class of problem as + the fabrication being removed, just in a more defensible direction. +2. **It leaves every fabricated timestamp in place.** Untouched, the history + still contains commits dated before the repository existed. + +The identity mapping is in [`scripts/provenance-mailmap.txt`](provenance-mailmap.txt). +Read it before running. If you prefer that those commits be explicitly +unattributed rather than attributed to the owner, change the target address on +each line to a marker such as `Unattributed ` — that is +honest, and it needs no guesswork. + +## Approach C — clamping the dates (removed) + +An earlier version of this script moved impossible dates forward to a marker +constant. It has been deleted. + +It is worth explaining why, because it looks reasonable. Clamping a commit dated +2025-01-14 to the repository-creation marker produces a date that is not false: +the commit really was created after the repository existed. But it is not the +date of the work either, and there is no way for a later reader to tell the +difference. It replaces an impossible date with a plausible-looking wrong one, +which is a strictly worse failure mode: an impossible date announces itself, +and a plausible one does not. + +If the dates are unknowable, the honest options are "no commit history" or +"dates that say they are not the original dates".
