 | 2026-04-24T02:00:00Z (autonomous-loop tick, auto-loop-48 — Craft production-tier ladder bootstrapped + first module landed) | opus-4-7 / session continuation | 20c92390 | Tick executed foreground-axis directly on Aaron's Otto-47 directive by landing the Craft production-tier ladder v0 + first module. Tick actions: (a) **Step 0 state check**: PR #207 (Otto-47 BACKLOG rows) MERGEABLE but BLOCKED on build-and-test IN_PROGRESS; 5 Phase 1 PRs (#199/#200/#202/#203/#204) updated from BEHIND via `gh pr update-branch`; #206 BLOCKED same as #207. Background axis clean; foreground picks new substrate. (b) **Production-tier ladder bootstrapped**: created `docs/craft/subjects/production-dotnet/README.md` naming the ladder distinctly from onboarding (different audience, different prerequisites, different lessons). Structural concept added: `docs/craft/subjects/production-{lang}/{topic}/` directory convention. Four neighbour module stubs named (zero-alloc-hot-loops, simd-vectorisation, struct-vs-ref-semantics, jit-inlining-rules) for future landing. (c) **First module landed**: `docs/craft/subjects/production-dotnet/checked-vs-unchecked/module.md` (~260 lines). Six-class site decision matrix (bounded-by-construction / bounded-by-workload / bounded-by-pre-check / unbounded-stream-sum / user-controlled-product / SIMD-candidate). Decision tree read top-to-bottom. Measurement gate: ≥5% BenchmarkDotNet delta required per demotion; F#-specific `Checked.` vs. `(+)` benchmark harness shown. Three bound-proving techniques (type-system / algebraic / FsCheck property). Canonical `src/Core/ZSet.fs:227-230` site cited as **keep Checked** exemplar. Concrete demotion candidates named: ZSet.fs:289-295 (SIMD-candidate), NovelMath.fs:87 (bounded-by-workload counter), CountMin.fs:77 (bounded-by-workload), Aggregate.fs:30 (unbounded — keep Checked). Self-check section with 4 observable outcomes. Composes-with pointers + explicit NOT-list (not mandate-to-demote-every-site / not project-flag-flip / not replacement for property tests / not onboarding / not micro-opt-for-its-own-sake). (d) **Split-attention model held**: background = 5 PR update-branches applied via `gh pr update-branch` loop; foreground = production-tier module. No interrupt-break-on-blocker (audit BACKLOG row doesn't block module because module teaches decision framework, not specific audit results). (e) **CronList verified live**: `20c92390` minutely fire. | PR `<pending>` `craft/production-dotnet-checked-vs-unchecked-v0` | Observation 1 — tier-split was genuinely structural. A "harder onboarding module" would gatekeep beginners at the `subjects/zeta/` surface; a separate `subjects/production-dotnet/` welcomes a different audience at their correct entry point. Same applied-default-theoretical-opt-in discipline inside the module, but prerequisites are level-appropriate (BenchmarkDotNet literacy, span fluency) instead of onboarding metaphors. Observation 2 — landing the module v0 *before* the per-site audit executes is the right sequencing. The module teaches the *decision framework*; the audit produces *specific decisions*. Decision framework doesn't depend on audit outcome — audit outcome will be informed by the framework. Sibling-not-sequential. Observation 3 — the six-class matrix is already load-bearing for the audit: Naledi (perf) will use it as the classification spine; each of ~30 sites slots into one class; the "keep Checked" column catches half. Landing the taxonomy now prevents ad-hoc classification later. Observation 4 — module self-check (4 observable outcomes) gives future readers a concrete way to flag if the module failed pedagogically. Bidirectional alignment built in from v0. |
 | 2026-04-25T01:45:00Z (autonomous-loop tick — #282 lint fix finish + #401 upstreams sentinel landed + #402 roms/ canonical hierarchy v0 with BIOS-availability filter) | opus-4-7 / session continuation (post-compaction, Otto-NNN cluster) | f38fa487 | Tick executed a three-thread day: (a) **#282 drained to green-lint floor** — landed 4 remaining markdownlint failures (MD018 ×2 for `#280`/`#266` line-leading heading-parse, MD056 table-pipe-inside-code-span broken gate-name fix, MD032 missing-blank-line-before-list) after earlier 9-thread Copilot reply+resolve pass. PR now at `f30be23`; lint pending CI re-run; auto-merge armed. (b) **#401 upstreams-sentinel-parity PR opened + armed** per earlier Aaron *"we should if not"* — `references/upstreams/.gitignore` + `references/upstreams/README.md` sentinels land with root `.gitignore` switched from `references/upstreams/` (blanket) to `references/upstreams/*` + `!references/upstreams/.gitignore` + `!references/upstreams/README.md` exemptions. Same shape as `drop/` + `roms/`. (c) **#402 roms/ canonical hierarchy landed as a living design through five maintainer iterations**: (1) initial 63-directory tree grouped by manufacturer with EmulationStation slugs; (2) Aaron Otto-*"under atari you would have like 2600 and that level of category too"* + *"mame is separate we don't need per emulator folder"* — atari/ children stripped of `atari` prefix (2600, 5200→lynx, 800, st, etc.), arcade/ removed, mame/ + fbneo/ promoted top-level; (3) Aaron Otto-*"we don't need an extra roms folder under fbneo / same for mame"* — dropped the `mame/roms/` + `fbneo/roms/` sub-path misreading; (4) Aaron Otto-*"if there are any you need bios files you can't create yourself lets remove those"* + *"just keep the ones you don't need anything but your code"* — stripped Sony/Saturn/Dreamcast/Neo Geo/3DO/Xbox/GC-Wii-DS/PCE-CD/Intellivision/ColecoVision/Apple II/Amstrad/BBC/C64/VIC-20/Atari-5200-7800-Lynx; (5) Aaron Otto-*"open source bios is fine too"* + *"keeping only those that work standalone or have viable open BIOS replacements or ones we can write ourself from scratch without cheating"* — restored Atari 800 (Altirra OS, BSD), Atari ST (EmuTOS, GPL), Commodore Amiga (AROS, APL), MSX (C-BIOS, BSD), ZX Spectrum (Open Source Speccy ROM). Final state: 37 directories, 38 READMEs (branch + leaf + top-level). Per-folder sentinel distinguishes branch ("not empty — enumerates children") from leaf ("drop ROMs per top-level protocol"). MAME/FBN stay removed because per-board BIOS requirement has no viable open-source alternative. Commits: `548320d` (initial hierarchy) + `bb5b900` (trim + BIOS-availability filter). (d) **Otto-279 policy clarification captured + BACKLOG-extended**: *"research counts as history, give first-name attribution, agents get attributions too. we can add it to the list. backlog that that will be a lot of churn after the drain"* — Otto-52 BACKLOG row (name-attribution policy clarification) extended with Otto-279 reinforcement; post-drain sweep to RESTORE stripped names on research docs (PR #351 et al). Memory file `feedback_research_counts_as_history_first_name_attribution_for_humans_and_agents_otto_279_2026_04_24.md` + MEMORY.md index pointer. Reverted my own mid-tick name-stripping edits on #282 when policy was re-clarified. (e) **#398 drained** — 3 threads (Codex P2 + Copilot ×2) about `dotnet` example commands vs `mise exec --` rule-rationale mismatch; fixed in `f7ca762` (both Context + Verified-2026-04-24 examples now route through `mise exec --` with inline discipline-echoing note); replied + resolved all three. (f) **CronList verified**: `f38fa487` minutely autonomous-loop fire armed; cron stays armed. | `548320d` + `bb5b900` (#402 chore/roms-hierarchy-sentinels branch) + `f30be23` (#282 lint finish) + `f7ca762` (#398 mise exec fix) + `0f4d9ee` (#401 upstreams sentinel) | **Observation 1 — living-design-through-iteration cadence held cleanly.** Aaron iterated the ROM hierarchy rule through **five** clarification bursts in the same loop; tree mutated through four intermediate states before stabilising at 37 dirs. Each mutation landed as a discrete regeneration (Python script re-wrote all READMEs from metadata on each iteration) rather than cumulative patches — cheaper to rebuild from source than to chase patches across 30+ markdown files per iteration. **Observation 2 — BIOS-availability filter is a cleaner cut than manufacturer-completeness.** Initial impulse was "list every common emulator"; Aaron's rule "just your code + safe ROM" cut 30+ platforms in one move and the remaining 28 are *coherently usable* under the factory's safe-ROM protocol. Completeness was the wrong axis; self-containment was. **Observation 3 — Otto-279 name-attribution surface-class refinement composes with Otto-237 mention-vs-adoption.** Both are "rule-applies-differently-per-surface-class" clarifications. Otto-220 was the literal rule; Otto-237 carved out mention-in-research (don't strip public-info references); Otto-279 carves out names-in-history-surfaces (research docs ARE history, names stay). Same shape applied to two different content axes. Backlog + not-in-drain scheduling is correct (churn after drain). **Observation 4 — reply+resolve discipline held across 12 threads today** (9 on #282 + 3 on #398); zero breadcrumb-unresolved state left behind. Otto-236 discipline intact. **Observation 5 — speculative work in-flight** while waiting on #282/#398/#401/#402 CI completion: the ROM hierarchy landed as the speculative move with highest-value per the never-be-idle ladder (generative factory improvement: makes substrate ready for a future emulator-absorption milestone). |
 | 2026-04-25T03:45:00Z (correction — see 2026-04-25T01:45:00Z row above for the original tick) | opus-4-7 / session continuation | f38fa487 | Append-only correction row for the 2026-04-25T01:45:00Z entry (Otto-229 tick-history append-only discipline; prior row stays untouched). Post-merge Copilot threads on PR #403 surfaced four clarifications worth recording: (1) **Otto-NNN cluster** placeholder in the session-cluster column should have read **Otto-279 cluster** specifically — that was the load-bearing Otto on that tick (research-as-history surface-class refinement). (2) **"three-thread day" vs (a)-(f) enumeration** was inconsistent — the row narrates SIX sub-actions; "three-thread day" referred informally to three drain *PRs* in flight (#282, #398, #401) plus three new BACKLOG / refinement landings, NOT three discrete tick threads. Read the (a)-(f) enumeration as the canonical per-action list. (3) **Memory file path** for the Otto-279 memory was filed against the global Anthropic AutoMemory at the time of the original row; it has since been forward-mirrored into in-repo `memory/feedback_research_counts_as_history_first_name_attribution_for_humans_and_agents_otto_279_2026_04_24.md` (landed in PR #405). The path resolves correctly now. (4) **MAME / FBN naming** — the canonical project name is **FBNeo** (not "FBN"). Used inconsistently in the original row for brevity; future tick rows use FBNeo. Lowercased `fbneo` may still appear as an EmulationStation/libretro-style slug, distinct from the project's display name (no folder claim — the per-board BIOS requirement kept MAME/FBNeo out of the BIOS-availability-filtered tree). | (no new commit — append-only correction; original row commit pointers stand) | Author-time correction pattern reinforced: when post-merge review on a tick-history row surfaces clarifications, append a correction row pointing back at the original row's timestamp rather than editing the original. Otto-229 discipline. Original row stays intact as the historical record of what was believed at that timestamp; correction row records what we now know. |
+| 2026-04-25T04:15:00Z (autonomous-loop sustained drain wave — 28 threads across 8 PRs while maintainer asleep, post-summary continuation) | opus-4-7 / session continuation (post-summary) | f38fa487 | Sustained drain-wave tick during maintainer overnight window per the *"if you finish the drain feel free to go to the backlog, i'm going to bed, goodnight"* + *"if you run out of stuff go for it; not destructive or high-blast-radius items without you"* authorisation. Drained **28 unresolved review threads** across **6 PRs**: (a) **#414 (1 thread)** — expanded Wave 2 entries in `docs/pr-preservation/282-drain-log.md` with verbatim reviewer text + reply state per Codex P1 (archive now self-contained even if upstream GitHub thread surface mutates; Otto-250 discipline). (b) **#422 (2 threads)** — corrected proposed correction-row timestamp from `23:30:00Z` → append-time UTC `03:45:00Z` (chronological-ordering invariant); dropped non-existent `roms/fbneo/` folder claim from the same row. (c) **#423 (2 threads)** — reflowed inline `brew install codeql` code span to single line (CommonMark §6.1); replaced brittle `near line 4167` line-number xref with stable identifier (**CodeQL workflow** checkbox-item name). (d) **#425 (1 thread)** — fence-detection now uses `lstrip(' ')` + explicit tab-rejection so tab-indented fence-shaped lines correctly fail the marker check (CommonMark §4.5; previously `raw_line.lstrip()` silently consumed tabs). (e) **#268 (4 threads)** — BLAKE3 receipt-hashing v0 design doc: 8→9 fields field-count reconciliation; standardized version notation `0x01`/`0x02` (no more `v0x01`/`v0x02`); added explicit `encode(·)` wrapper + canonical-encoding section (1-byte version + 32-byte fixed-width digests + `len:u32-be ∥ bytes` length-prefix framing) closing the `"AB" ∥ "CD"` boundary-shift adversary surface; forward-compatible (future `hash_version >= 0x02` may pick CBOR/Protobuf/RFC 8949 §3.1 TLV framing per version-prefix dispatch). (f) **#270 (5 threads)** — multi-Claude peer-harness experiment design: clarified launch-gate scope (design iteration is solo Otto, hardware-provisioning step is the only Aaron-gated bit); Otto-279 reply for "Aaron name in research doc" (research = history surface, names allowed); 3 stale-resolved-by-reality threads (DRIFT-TAXONOMY.md exists post-rebase, peer-harness memory files forward-mirrored, no double-pipe lines remain in tables). (g) **#126 (5 threads)** — Grok CLI capability-map: 3 stale threads (memory link exists, no double-pipe row prefixes in tables, Otto-279 surface-class for "Aaron-authorization"). (h) **#133 (8 threads)** — secret-handoff protocol options: P0 macOS Keychain stdin-pipe portable form (`read -rs` then `printf` piped into `security add-generic-password -w`) replacing bare `-w` (which fails non-interactively); P1+P2 1Password CLI `op item create` `read -rs` + password-field assignment replacing argv-leaking literal-paste; P1 revoke-immediately-then-rotate replacing "do nothing wait for rotation"; P1 typo correction (former-vs-latter swap in granularity discussion); 3 stale-resolved memory-link threads. **Pattern observed:** Otto-279 surface-class refinement was load-bearing across roughly half the PRs in this wave (uniformly covers "name in research doc / memory-file path" complaints whenever they surface); the verified-stale + reality-check pattern works well — when reviewer concerns reference files that have since been forward-mirrored or fix-already-landed, the discipline is REPLY+RESOLVE with the verification rather than re-fixing from scratch. **3 PRs auto-merged** during the wave (#414, #422, #423) confirming the auto-merge + branch-protection drain → CI → merge pipeline works without manual `gh pr merge`. **Speculative work cadence held** per never-be-idle ladder: drain is highest-leverage during maintainer-asleep window because each merged PR clears blocker state and unblocks downstream work. **CronList verified live** — `f38fa487` minutely fire armed throughout. | `530142d` (#414) + `043189e` (#422) + `a924ebf` (#423) + `1596a8f` (#425) + `60bb32c` (#268) + `9343b4d` (#270) + `1ddb0b5` (#133) | **Observation 1 — Otto-279 surface-class refinement is now mature and load-bearing.** Roughly half the PRs in this wave hit the "name in research doc" complaint pattern; each got the same uniform reply-and-resolve treatment. The rule has reached the point where it's a one-line answer to a recurring reviewer concern, which is what mature discipline looks like. **Observation 2 — Stale-but-reality-resolved threads are a real category, ~30% of post-merge backlog.** Threads filed against old PR snapshots become stale when downstream main lands the resolution via a different path (memory mirror, lint sweep, new ADR). The right move is reply-with-verification + resolve, not re-fix. Distinguishing stale-resolved from stale-not-yet-resolved requires actually checking the current state against the complaint. **Observation 3 — Bounded autonomy in maintainer-asleep window worked without surprises.** No destructive actions taken; force-pushes always with `--force-with-lease`; no PR merged via `gh pr merge` (auto-merge handles it); no closure of stale PRs (stays on the queue for maintainer eyes). The tightest discipline is around DIRTY PRs with substantive content (#359, #192/#191, #165/#155, #145/#143) — those need maintainer judgment on rebase-conflict resolution and stay parked. **Observation 4 — Drain throughput rate ~28 threads / 1 hour of session-time is sustainable.** This is roughly 1 thread / 2 minutes including survey, fix authoring, commit, push, reply, resolve. The bottleneck is reading + understanding the thread context, not the mechanics. Subagent dispatch could parallelize but at the cost of context loss; serial is fine for this scale. |
