From d376cad1b87243d6f5393e633905699c32603515 Mon Sep 17 00:00:00 2001 From: Claude Date: Tue, 4 Aug 2026 17:41:10 +0000 Subject: [PATCH] =?UTF-8?q?docs:=20cite=20all=20three=20diagnostic=20runs;?= =?UTF-8?q?=20record=20(g)=20=E2=80=94=20the=20window=20is=20bounded?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Promotes the missing citations per the out-of-environment rule: readd_after_delete_1785797173.json for (a)-(c), readd_after_delete_1785800147.json for (d)-(e), and readd_after_delete_1785828208.json for (f)/(g). Records (g): WRITE_VISIBLE, retrievable 0s after a 60s settle, 3 reads, 4 units. With (f) that resolves the open fork onto the branch stated in advance for transient reaping. The window after a delete_all is real — polling a namespace until empty is not sufficient — and bounded, since a 60s settle cleared it completely. delete_all stays usable as a reset primitive provided the caller verifies writability instead of trusting emptiness, which is what the sentinel does. Every per-key arm passed; the one delete_all arm failed. Corrects my own framing from the previous entry, which said (f) shows the condition persisting for at least 120s. That reads as a claim about the window and is not one: (f) polls a single already-swallowed write, which is dead permanently, so 120s measures how long we waited rather than how long the store reaps. (g) is the only bound on the window and bounds it from above at 60s; the lower bound is unmeasured. Corrected in a new entry rather than edited in place, since the entry is merged. _CONVERGE_TIMEOUT stays at 30s. The window lies in (0s, 60s] and the sentinel's retry procedure differs from the arm's single-write one, so the empty_to_writable_s series sizes it, not a guess. Cites the 003 abort as terminal-reported with its provenance — mem0 adapter, seeds 2, founder's Mac, 2026-08-03, op #26 (003-scope-boundaries seed 0, write, 31.20s) — and states plainly that no results file exists for it. Adds the inference, marked as inference, that op #26 is the first write after that scenario's reset, since op counts are structural: ops 25-29 with op 25 the reset. That is the (f) condition, and 31.20s sits just past the 30s write-convergence ceiling. Unmeasured because the run predates the [reset] logging. Also brings the diagnostic's STATUS block up to date; it still said (d)-(g) had not run.

If it typically sits under +30s the loop converges; if it sits above, `reset()` exhausts its budget and +raises — safe, but it would abort runs. **Still not enough information to size +it, and still not worth guessing at**: `empty_to_writable_s`, emitted on every +deleting reset since `e7e89dc`, measures the window directly and under the +retry procedure rather than the single-write one. First real run settles it. + +**The `003` abort — terminal-reported, no results file.** Provenance: +`memorycheck run scenarios --adapter mem0 --seeds 2`, founder's Mac, +2026-08-03, terminal output only. Aborted at **op #26 — +`003-scope-boundaries` seed 0, `write`, 31.20s**. There is no +`diagnostics/results/` artefact for this one; it is cited as terminal-reported +rather than as a file, and should not be written up as though a JSON exists. + +**An inference about op #26, marked as inference.** Operation counts are +structural — fixed by the scenario pack and step list, not by the provider. On +that ordering, `003-scope-boundaries` seed 0 occupies ops 25-29, with op 25 +the `reset` and **op 26 the scenario's first write**. So the abort landed on +the first write immediately after a reset, which is precisely the (f) +condition. 31.20s is also just past the adapter's 30s write-convergence +ceiling, consistent with a write that was swallowed rather than merely slow. + +For that reset to have deleted at all, the namespace must have held residue — +which happens when a namespace name recurs, e.g. re-running the suite after an +earlier aborted run. That fits, but it is **not measured**: the run predates +the `[reset]` logging, so nothing recorded whether that reset took the delete +path. The next run answers it directly. + +### 3.
