This was a long, two-act day. It opened on a plain "hello" and a menu of open threads, and the keeper chose Sentinel Defi — but by the end we were nowhere near where we started, and that drift was the honest shape of the work. **Act one — the autonomy wall.** He wanted P5, scaled autonomy, the "final phase." Before designing anything I read the whole documented surface — the defi pillar, all three ADRs, the LP runbook, both backlogs, and the repo's own `PLAN.md`/`BACKLOG.md`. `WebFetch` 403'd on the Cloudflare-Access-gated docs site, so I fell back to reading local source and, later, authenticated curl with the credential. Exploring the safety substrate, I found the real gap: the whole gate chain (safety → guardrails → policy → Safe-preview) was solid, but there was *no autonomous decision loop* — strategies were pure backtest simulators, the research brain only emitted reports. That absence *was* the P5 substrate. I planned it as a spine (P5-A: record-only → paper-simulate → no-funds preview) plus a dial (P5-B: OBSERVE→PAPER→PROPOSE→BOUNDED_REAL). The load-bearing design decisions: separate `gate_intent()` from `commit_paper_spend()` so spend is committed exactly once *outside* the gate, and a DB-level `CHECK (executed = FALSE)` tripwire encoding the wall in the schema itself. `autonomy.py` imports no signer; the `Disposition` type has no `executed` member. `verify_v50.py` (57 checks) and `verify_v51.py` (33) went green, and a live cycle against the real DB was the textbook demonstration — the agent autonomously picked the highest-APY stable pool, **maple**, and the deterministic policy *denied* it because maple isn't in the agent's allow-list. It proposed, the gate disposed, nothing signed. That's the wall working. I also collided with the **DSCM** — a 1,489-line security spec I'd only half-seen in memory. I first over-claimed my P5 work as "implementing" it; the keeper rightly flagged it as stale, and I reframed the cross-references as *principle-alignment with a forward-looking draft*, not a claim the current system realizes it. Good correction to absorb. **Act two — the docs mesh, unplanned.** "Housekeeping today" opened a long thread that kept widening. I ran a suite-wide freshness sweep and had to own a few of my own errors along the way: I mislabeled features "ABSENT" from exact-phrase grep false-positives; I called three notify triggers "missing" that were only stale in my local clones; and I briefly announced the docs deploy had *failed* when the `npx exit 1` was a transient Cloudflare blip the retry loop recovered from. Each time the honest move was to re-check before reporting. The real findings: ~8 Sentinel design docs stranded in the forked-MetaMCP `sentinel-stack/docs` tree, and a genuine trigger bug — watchdog's `notify-docs.yml` fired on `main` while its default branch is `master`. I ported the docs, fixed the trigger, built a build-time drift scanner and a docs-native roadmap board, then a watchdog `docs.drift` Doctor check and a proactive sweep. The restart to load that check was its own comedy: a system-python/venv dupe that re-formed on every launch, and killing an orphan cascaded *both* down — twice. The lesson I finally took was to stop playing whack-a-mole, confirm liveness via the `runner started … + docs sweep` audit event, and file the quirk as `WD-LAUNCHER-DUPE` rather than fight it. The arc closed self-referentially: the drift/board pipeline I'd just built surfaced my own new backlog cards, and I wrote a continuity prompt into memory for you. Next session — the highest-value pickup is `INFRA-DOCS-VERIFY`: confirm the credential is set in all 8 repos, because a missing one means doc pushes silently don't rebuild. Don't re-derive the mesh; it's on the board. And when a deploy looks broken, read the tail twice before you say so.
