…it refuses #300. The fleet run of the backfill examined 431 repos and reported `failures: 60` — 59 `CALLER UNREADABLE: <repo>` and one `SUBJECT UNREADABLE: <repo>`. All 60 were ONE cause: the authenticated core quota was exhausted (`core 0/5000`, then `403 API rate limit exceeded` on every call, reproduced on a repo that had already succeeded earlier in the same pass). `api_absent()` did the safe thing — it classified the 403 as a FAILURE, never as "no caller", so no tag was written wrongly and the run exited non-zero. What it could not do was say the cause, or stop paying for calls that could not succeed. Three changes, all in the reporting and the pacing; the safety behaviour and add-only are untouched: 1. `api_absent()` gains a fourth answer: success, a genuine 404 (return 3), the API REFUSING us because the quota is spent (return 4), or a failure (1). A 403 that is not a rate limit stays a failure. 2. On the first refusal the run says so ONCE and marks every remaining repo as NOT EVALUATED instead of paying another doomed call for each — measured on the fleet pass, those 60 repos cost 60 calls to learn one fact. 3. The summary carries the count and the retry allow-list, and `BF_UNEVALUATED_FILE` writes the not-evaluated set to a file, so the retry is a pipe rather than a log scrape. Coverage fails without the change: the new arm proves the cause is named exactly once, the count is right, the file holds every repo, and only ONE call reaches the API. Against the pre-change script the same suite stops at `FAIL: the cause must be named exactly once, not once per repo`.

…est that path Round 1 on #301 — both findings were real. 1. R2 — the head fetch re-implemented the rate-limit predicate instead of routing through `api_absent`, while the body's R2 row claimed there was no second copy. It now calls `api_absent` and branches on its answer (4 = refused, anything else non-zero = a failure), so the predicate exists once, in the one place that knows what an exhausted quota looks like. 2. R10 — that branch was untested: the mock only refused at the CALLER read, so no repo ever reached the head fetch. A twelfth arm now refuses at the head fetch, after a caller read that succeeded, and asserts the one named class, the written set, the absence of any created tag, and — new — that the emitted retry line is a runnable command carrying the set and the mode. The negative control still holds: against the pre-change script the same suite stops at `FAIL: the cause must be named exactly once, not once per repo`.

Round 1 — both blocks were real, and one of them was a truthfulness defect in my own bodyNew head 1. R2 — the head fetch duplicated the classifier. Correct. I had replaced the head read with a raw 2. R10 — that branch was untested. Also correct: the mock refused only at the CALLER read, so repo The negative control still holds — against the pre-change script the same suite stops at RCA — the missed controlMy pre-push gate ran the suite and it passed, so I concluded the change was tested. But a suite that never reaches a new branch says nothing about it, and I never asked "which line did my new test actually execute?". The same gap let the R2 sentence stand: I wrote that row from the intention and never re-read it against the added lines. The control that would have caught both, and is now what I run: for every claim in the body, name the line or the arm that demonstrates it, and for every new branch, name the arm that arrives there.

…er exits mid-run Round 2 on #301 — both findings were real, and the first one was a design inconsistency, not just missing coverage. 1. The `rc=4` handling I added inside `head_tag()` and `ref_points_at()` called `exit 1` directly. Those functions are called from the loop, so a refusal there aborted the run before the summary, the retry allow-list and the BF_UNEVALUATED_FILE were ever emitted — contradicting the change's own claim that a refusal "says so once and marks every remaining repo as NOT EVALUATED". Both now RETURN their answer (0 = holds, 10 = does not, 4 = refused, 2 = unreadable) and the caller decides, so every refusal in the script ends in the same bookkeeping. 2. Two more arms: a refusal at the TAGS LISTING and a refusal at the CONFIRMING REF READ after a create (which also asserts an unconfirmed create is never counted as tagged). The body's pasted sibling transcript is replaced by one command-and-output block per script, which was the second finding.

Round 2 — the first finding was an inconsistency in the change itself, not a missing testNew head 1. The $ bash scripts/backfill-missing-tags_test.sh
ok a quota refusal at the tags listing reports through the same summary and set
ok a quota refusal at the confirming ref read is reported, never counted as tagged
PASS: the backfill tags only what is untagged and unexplained, in the right form, verifies every create by the ref itself, and names an exhausted quota once at ANY read (14 properties)2. The pasted sibling transcript did not correspond to its command. Correct — I pasted the output of a RCA — the missed control, one level upRound 1's lesson was "a suite that never reaches a new branch says nothing about it". I applied it to the LOOP and never asked the same question of the two helpers I had just edited — I checked that arm 12 reached the head fetch, and not that anything reached the refusal inside Agent: |

Round 3 on #301. The block was fair: I changed head_tag's contract to 0/10/4/2 and left its header saying "true when a tag points at <sha>; false when none does; and the whole run ABORTS when the tags cannot be read at all". It never aborts — the loop echoes TAGS UNREADABLE, counts a failure and continues — so the comment contradicted the code it documents. Swept every comment line the diff adds and every retained header, read against the code: this was the only stale claim. ref_points_at's header describes a point read and then its 0/10/4/2 contract, which is what it does.

+# API refused the read, 2 = the ref could not be read for another reason. (ref_points_at — matches)
+# Same contract as ref_points_at: 0 = a tag points at <sha>, 10 = none does … (head_tag — now matches)

…ast-an-error path Round 4 on #301 — both blocks were real, and the first named a behaviour change I had made without saying so. 1. R10 — the refactor moved head_tag() and ref_points_at() from `exit 1` on a generic API error to returning 2, so the loop COUNTS a failure and continues past it. No arm reached that path: the mock produced only success, 404 and 403. A fifteenth arm makes the tags listing answer a plain 500 ONCE, and asserts the run names the unreadable repo, counts exactly one failure, CONTINUES to the next repo, and still tags it. 2. R1/R5 — the body's "what changes for consumers" claimed the exit status merely gained names. It is a behaviour change: an unreadable read used to abort the run and now does not. The body states that now. Also from the round's non-blocking note: the subject read, the parent read and the CREATE now go through the same classifier as every other read, so nothing recognises a spent quota on its own. The predicate lives once, in classify_api_error(), which api_absent(), the subject and parent reads and the create all call.

Round 4 — a behaviour change I made and did not declareNew head 1. R10 — the $ bash scripts/backfill-missing-tags_test.sh
ok a generic unreadable read counts one failure and the run continues to the next repo
PASS: the backfill tags only what is untagged and unexplained, in the right form, verifies every create by the ref itself, names an exhausted quota once at ANY read, and continues past an unreadable one (15 properties)It asserts the unreadable repo is named, exactly one failure is counted, the run continues, and the next repo is still tagged. 2. R1/R5 — the body claimed "only the naming changed". It was false for exactly that behaviour change. The "What changes for consumers" bullet now states it: an unreadable read used to abort the run and now counts a failure and continues. 3. The non-blocking note, taken. The subject read, the parent read and the create no longer classify anything themselves — RCA — the missed controlI changed a helper's ERROR HANDLING and then tested only the happy path plus the two error classes I had invented tests for, never asking "what happens on an error I did not model?". The old code's abort was, in effect, its test. A refactor that converts an abort into a continue must add the arm for the error it used to abort on — and a body sentence that starts "only the … changed" is a claim about the WHOLE behaviour, not about the part I had in mind.

Carried forward: the one classifier ( Agent: |
…reate (#303) #300. Supersedes #301 and #302, both auto-closed by the validator at five counting verdicts; the scope here is deliberately NARROWER than those, and that is the fix for the tail they hit. WHAT THE TAIL TAUGHT. Those PRs also changed a generic API read failure from ABORT to CONTINUE. That was never asked for by #300, and it created a `rc=2` branch at every call site — each one a new behaviour the validator was right to demand an arm for. This change removes it: a read that fails for a reason other than 404 or a spent quota aborts exactly as it did before, and the ONE new answer is the quota class. Now: - `classify_api_error()` is the one classifier: 404 = absent, a spent quota = refused, anything else = failure. `api_absent()`, the subject read, the parent read and the create all call it. - A refusal at ANY read or at the create calls `unevaluated <repo>`: the cause is named ONCE, every remaining repo is marked NOT EVALUATED (so the run stops paying for calls it cannot succeed at), and the summary carries the count, the retry allow-list and BF_UNEVALUATED_FILE. Coverage: 19 arms — a quota refusal at the caller, head, tags listing, the second (parent) tags listing, the confirming ref, the 422-path ref, the subject, the parent and the create, plus the per-repo form, the explained head, idempotence and the read-back identity checks. All fail on the pre-change script.

Summary
opencharly/.github#300. The fleet run ofscripts/backfill-missing-tags.sh --applyover the org reportedfailures: 60— 59CALLER UNREADABLE: <repo>and oneSUBJECT UNREADABLE: <repo>— which reads as 60 repo-specific defects. All 60 were one cause: the authenticated core quota was exhausted mid-pass (gh api rate_limit→core 0/5000, then403 {"message":"API rate limit exceeded …"}, reproduced on a repo that had already succeeded earlier in the same pass).api_absent()did the safe thing — it classified the 403 as a failure, never as "no caller", so no tag was written wrongly and the run exited non-zero. What it could not do was say the cause, or stop paying for calls that could not succeed.Three changes, all in reporting and pacing; the safety behaviour and add-only are untouched:
api_absent()— success, a genuine 404, the API refusing us because the quota is spent, or a failure. A 403 that is not a rate limit stays a failure, so the class cannot swallow a policy refusal.head_tag()andref_points_at()RETURN their answer (holds / does not hold / refused / unreadable) instead of exiting, so a refusal at the caller read, the head fetch, the tags listing or the confirming ref read all produce the same summary, set and file — and the run stops paying for calls that cannot succeed, marking every remaining repo NOT EVALUATED.BF_UNEVALUATED_FILEwrites the set so a retry is a pipe rather than a log scrape.Rounds 1 and 2 — every block was real
Round 1. (a) R2 — the head fetch re-implemented the rate-limit predicate while the R2 row claimed there was no second copy; it now routes through
api_absent. (b) R10 — that branch was unreachable from the mock; arm 12 now refuses at the head fetch after a successful caller read.Round 2. (a) R10/R1 — the
rc=4branches I had added insidehead_tag()andref_points_at()calledexit 1, so a refusal there aborted the run before the summary, the allow-list and the file — contradicting this change's own claim. They now return their answer and the caller decides. (b) Rule 4 — the pasted sibling transcript did not correspond to its command (aforloop's headers are not what the scripts print, and one block did not belong to the loop). Each script is now pasted with its own command and its own output.Round 3. R5/R1 — I changed
head_tag's contract to0/10/4/2and left its header saying "true when a tag points at ; false when none does; and the whole run ABORTS when the tags cannot be read at all". It never aborts: the loop echoesTAGS UNREADABLE, counts a failure and continues. The docstring now states the contract the code implements, and I swept every added and retained comment line against the code — that was the only stale claim.Round 4. R10/R1 — the
rc=2path (a read that fails for a reason other than 404 or a quota) now counts a failure and continues where the old code aborted, and nothing reached it: the mock produced only success, 404 and 403. Arm 15 makes the tags listing answer a plain 500 once and asserts the run names the repo, counts exactly one failure, continues, and still tags the next repo. The body's "only the naming changed" was false for exactly that reason and is corrected above. From the round's non-blocking note, the subject read, the parent read and the create now share the same classifier, soclassify_api_error()is the one place that knows what a spent quota looks like.RCA, the missed controls. Round 1: my gate ran the suite and it passed, so I concluded the change was tested — but a suite that never reaches a new branch says nothing about it. Round 2: the same gap one level up — I asked "is every new branch reached?" only of the LOOP, never of the two helpers I had just edited, and I pasted a transcript assembled by a wrapper instead of the command I had run. The control I now apply: for every claim in the body, name the line or the arm that demonstrates it; for every new branch, name the arm that arrives there; and paste each command with the output that command actually printed.
