   Graded: promoted to pm:queue / Task, finding removed. Blocked-by: #197 — see the sequencing note at the end.

   Scope correction: the claim is now in BOTH files, not one. The card says llms-full.txt/route.ts "carries a similar block, but its claim is about getPages() only and is accurate." That was true of the tree you measured (9a1a7ad). It stopped being true nine minutes before you filed. Current main:

   apps/docs/app/llms.txt/route.ts:32-33

   source.getPages() and source.getPageTree() list every language when called without one

   apps/docs/app/llms-full.txt/route.ts — added by #196 (1ebd7b7), merged at 02:07

   source.getPages() and source.getPageTree() alike filter by locale only when a language is passed — called bare they list every language

   So the fix is two files.

   How the second copy got there is the interesting part

   #196 changed that route from enumerating getPages() to walking getPageTree(). Its dev noticed the LANG comment now named a call the route no longer makes, and updated it — correctly, and flagged as a declared deviation, and I accepted it on exactly that reasoning. In doing so it carried across the getPageTree() half of the sibling file's claim.

   That half had never been measured. It was true-sounding, adjacent to a claim that is true, and it propagated on the strength of being already written down.

   Two agents, an hour apart: one copied an unverified assertion into a second file, the other measured it and found it false. The measurement is what a comment claiming API behaviour needs and had never had. Same discipline as "a dispatch's hazard claims need a reading" — a comment asserting what a library does is a claim about code, and it is checkable in about two minutes, as you demonstrated.

   Keep the pin

   The card's judgement is right and the dispatch should carry it: the pin stays. Nothing in the API contract promises getPageTree() will keep defaulting to the default language, #184's gate (01b29d9) now asserts the output either way, and passing the language explicitly is correct regardless of what the current version happens to do when you omit it.

   What changes is the justification: attribute the leak to getPages(), where it was and still is, and state the getPageTree() position as "passes the language because the tree is per-locale and the default is not contractual" rather than as an observed leak. That is a stronger reason than the false one, and it survives a reader checking it.

   The failure mode this prevents

   A future reader verifies the comment in two minutes, finds the pin makes no difference to getPageTree, concludes the pin is cargo cult, and removes it — or writes the next route from this template without one. The comment is the only thing on either page explaining why LANG exists, and its stated reason currently comes back false when checked.

   Sequencing

   Blocked on #197, which is in flight on apps/docs/app/llms-full.txt/route.ts — one of your two files. If #197 lands as needs_decision without touching the file (a real possibility; it was dispatched as an investigation first), this unblocks immediately. Otherwise it unblocks on that merge.

   Clause-②: no

   Unblocked. #197 returned needs_decision with an empty diff and no PR, so llms-full.txt/route.ts was never touched and the serial constraint I set is gone. Nothing else is in flight on either of your files.

   Reproduce before you rewrite — that is the whole point of this card

   This card exists because an unmeasured claim propagated between two files on the strength of being already written down. Do not now write the replacement comment on the strength of this card's measurement without reproducing it. It is a two-minute check, which is precisely the argument the card makes.

   Drop the argument from source.getPageTree(LANG) in llms.txt/route.ts, rebuild, compare the llms.txt.body sha256 against the unmutated build, restore. The card got byte-identical hashes on 9a1a7ad; main has moved several times since, so confirm it still holds on your base. If it does not hold on current main, stop and report — that would mean the comment is now true and this card is void.

   Turbo cache trap: the cache is shared across worktrees and will replay a sibling's green. Use --force, and confirm the mutation is on disk before the build (occurrence count going 1 to 0), the way the card did — not by trusting an editor's exit code.

   What to write

   Per the grading comment: attribute the leak to getPages(), where it was and still is, and state the getPageTree() position as passes the language because the tree is per-locale and the default is not contractual — not as an observed leak. The pin stays in both files. The new justification is stronger than the false one and survives a reader checking it.

   Both copies need it. llms-full.txt/route.ts acquired its version from #196 nine minutes before the card was filed, which is why the card's own text says that file is accurate — it was, when measured.

   ACCEPT — merging #206.

   CI 2/2 green on add20b2b, base 3433803 (current main, post-#204), two files, comments only, no open questions.

   The instruction was "reproduce before you rewrite," and the report shows the reproduction, not a claim of one. Baseline hash, mutation confirmed on disk by occurrence count going 1 to 0, --force rebuild, byte-identical 883ebd38... — matching the hash the card recorded on a different commit days of churn ago. So the false half is still false and the card is not void, which is the branch I asked you to check for and the one that would have ended this differently.

   Two details above the ask:

   The restore was verified before the real edit began. git checkout HEAD -- ... then git diff HEAD empty, then proceed. An ablation that leaves its mutation in place quietly poisons everything measured afterwards, and the only symptom is numbers that look fine.

   "Comments only" was proved by output identity, not by reading the diff. llms.txt.body unchanged from baseline and llms-full.txt.body matching the digest recorded in #201's commit message. A comment-only change is exactly the kind of claim that is obvious enough to skip verifying, and this file has now twice been the place where an obvious-enough claim turned out wrong.

   And the archaeology closed the loop I had only inferred. git show c243ad7 establishes that #183's original fix was solely about getPages(), which confirms the account in the grading comment: the getPageTree() half was carried across with the code when #196 switched that route from enumerating pages to walking the tree. I had that as a reconstruction from timestamps; it is now sourced.

   The judgement in the PR body is right too — deleting the false half would have regressed nothing, since #184's gate asserts the output either way, but the comment is the only place either file explains why LANG exists, and a wrong "why" there is precisely what propagated once already. Replacing it with a reason that survives being checked is the fix; deleting it would have left the next reader with no reason at all.

   Closing the thread this card opened. Two agents, an hour apart, on the same sentence: one copied it into a second file because it was already written down, one measured it and found it false. The comment now says something a two-minute check confirms rather than contradicts.
