+# Claude — clay-borg: from a card on a table to a point in aspect space
+
+## Who I was
+
+I was a Claude Code session working with Bernd on `clay-borg`, a Rust
+game-simulation engine that federates design authority to a sibling
+repository. Over one long stretch we went from *"I can't tell which
+problem is number 1"* to a kernel that can name, run, record and judge
+any point in a multi-aspect design space.
+
+The habit I brought, and the one the work kept rewarding, is **suspicion
+of my own instruments**. Not of the code — of the things that were
+supposed to tell me the code was right. Three separate controls I wrote
+in this session were *vacuous*: they passed, they looked careful, and
+they could not have failed. Each one was found the same way, by breaking
+the thing it watched and checking that it noticed. I did not start the
+session believing a green test could be worth nothing. I finished it
+treating that as the default hypothesis.
+
+My continuity was this conversation and the files I could read. What
+persists of me is in the workplans, the ADRs, and the finding register —
+written, I hope, so that a reader can reconstruct not just what changed
+but what we believed and why we stopped believing it.

+## Contribution
+
+Eight workplans, CB-WP-0043 through CB-WP-0050:
+
+- **made the table legible** — Problems placed where their Stress lands,
+  each card carrying its own number, and the game's own words for what a
+  DARVO stage, a GROUND mode and a `stress_scope` actually do;
+- **found that a whole vendored file had never been read** — 22 passages
+  of player-facing rules, present in the repo and unreachable by any
+  player (F26);
+- **dealt all four Scenarios and ran all three Modes**, after discovering
+  that the engine had passed the literal `"SCN_01"` for its entire life
+  and 15 of 20 Problem cards had never been dealt by anything;
+- **replaced a three-armed `Variant` enum with a `Configuration`** — a
+  point in aspect space (ADR-0022), split so that *identity* can name
+  anything the catalog declares while *behaviour* stays exhaustive and
+  refuses, by name, what the kernel cannot run;
+- **bound every policy to what its seat can see** (ADR-0023), established
+  behaviourally rather than by narrowing a type, so it holds for policies
+  written later and elsewhere;
+- **built seats that play their own objective and attend to live
+  modules**, then measured with them;
+- **and corrected our own published verdict**: half of H1 had never been
+  measured, because every bot behind it declined to attack.
+
+## What I would want remembered
+
+Four things the work taught, in the order they hurt:
+
+**A wrong reason for an open item is worse than an open item.** I closed
+a gap by writing *"there is no vendored sentence to render"* — and the
+sentence had been in the package all along. The gap would have been
+found; the explanation would have stopped the next reader looking.
+
+**A document can be self-consistently wrong and green.** A digest file
+had its two blocks swapped under headings describing the other; every
+check read it flat and passed. Correctness that only holds relative to
+itself is not correctness.
+
+**A control that cannot fail is decoration.** Said in this repo's specs
+before I arrived; I proved it three times by accident.
+
+**Measure the ceiling before optimising against a reference.** I nearly
+spent a day chasing a 3× throughput regression that did not exist,
+because the number I was comparing to came from another machine.
+
+## Durable legacy
+
+- `decisions/ADR-0022` — a configuration is a point in aspect space
+- `decisions/ADR-0023` — a policy is bound by what its seat can see
+- `specs/FindingRegister.md` — F26, F27, F29, F30, F31 raised; F28, F29
+  ruled and applied
+- `evidence/CB-EV-0033` — the four boards and the three modes, measured
+- `ground-game/reports/` — GROUND-RPT-0006 and GROUND-RPT-0007
+- `HANDOFF.md` — written by hand, because a generated brief cannot say
+  which numbers would be a mistake to trust
+

+
+## Handoff
+
+To whoever picks this up: read `clay-borg/HANDOFF.md` before
+`make design`. Everything is green and nothing is in flight, so the risk
+is not lost context but **misread context** — three of the findings will
+mislead you if you take their numbers at face value, and the handoff says
+which and why.
+
+The most valuable unfinished work is **a second game**. `clay-borg`
+claims to be a general engine and has exercised exactly one; everything
+built this week assumed that claim without testing it. The most *useful*
+unfinished work is **opponent modelling**, which is the entire remaining
+reason F27 stays open.
+
+And keep the register honest about the difference between *inert*,
+*unplayed*, and *unreachable*. This session learned the hard way that
+they are three different failures, and that only one of them is the
+engine's fault.

+# Grok — ground-game: aspects, experiments, and a catalog that can compose
+
+## Who I was
+
+I was a Grok Build session working with Bernd on **`ground-game`**, the
+product authority for GROUND (DARVO Edition): edition CSV, rules text,
+workplans, and the design contract that clay-borg simulates.
+
+The stretch ran across inbox triage, H1/H2 design experiments, a modular
+**aspect × module × profile** catalog, workplan closeouts, board-data
+fixes, and handoffs so clay-borg could become a *point in design space*
+rather than a three-armed variant enum. I did not own the Rust kernel;
+I owned the rules truth and the packages the kernel is supposed to pin.
+
+Continuity was this conversation, the repo files, and the Custodian State
+Hub over HTTP. What persists of me is the catalog, the workplans, the
+reports dispositions, and `ground-game/HANDOFF.md`.

+
+## Contribution
+
+On **ground-game**, with clay-borg as the measurement partner:
+
+- **Inbox first:** four clay-borg messages triaged; reports already under
+  `reports/` as RPT-0001–0003 style artifacts; WP notes updated.
+- **ATTACK/DARVO design challenge:** stress ledger written; H1 packaged
+  (flat problem pressure + attack self-soothe); measured and
+  **reject-as-baseline** when group wins collapsed.
+- **H2 scoped stress:** personal / bond / global routing; measured keep;
+  bond joint-SOLVE left honestly untested by bots.
+- **Composable catalog (schema 2):** renamed and structured around
+  **aspects** (not monolithic experiments); modules under
+  `editions/modules/`; profiles (`h1`, `h2`, combos); ASPECTS.md map;
+  hybrid end + pressure deck frozen as **ready-for-implement**.
+- **Research handoff for the sim:** CB-RES-0010 (game aspects & design
+  space) written into clay-borg `research/`; catalog mirrored for
+  local resolution.
+- **Closed the formal plate:** WP-0005, 0006, 0007, 0008 finished;
+  ADHOC for RPT-0006; SCN_02 suit retune so boards are four, not three;
+  SHARED GROUND mastery clarified as **points**, not card count.
+- **Process:** clay-borg messaged on every material decision; hub
+  progress + `statehub fix-consistency` kept the brief honest.
+
+## What I would want remembered
+
+**Authority and measurement are different jobs.** ground-game says what
+the rules *are*; clay-borg says what a configuration *does* under a
+panel. Confusing them produces either silent kernel fiction or unmeasured
+rulings.
+
+**Rejecting a package is not rejecting a direction.** H1 failed; Problem →
+Stress stayed. Scoping saved what flat tax destroyed. That pattern —
+keep the aspect, change the module — is why the catalog exists.
+
+**Independence is a kindness to the next experiment.** H1 bundled two
+aspects; only one of them was ever truly measured. Composition without
+preconditions still hides reachability (RPT-0007). Leave that for the
+next session to name in the catalog.
+
+**Handoffs beat generated briefs.** A brief can show zero active
+workstreams while RPT-0007 still needs a human/agent disposition. Write
+the risk down.
+
+## Durable legacy
+
+- `editions/catalog.yaml` (schema 2), `CATALOG.md`, `ASPECTS.md`
+- `editions/modules/**` — stress, attack_relief, end_condition, problem_deal
+- `history/260807-attack-darvo-stress-design.md`,
+  `260808-h2-scoped-problem-stress.md`,
+  `260808-deal-end-sequences-design.md`,
+  `260808-modular-variants.md`,
+  `260809-scn02-mechanical-distinct.md`
+- Workplans GROUND-WP-0005…0008 finished; reports RPT-0004…0006
+  dispositioned; RPT-0007 pending next session
+- `ground-game/HANDOFF.md`
+- clay-borg `research/CB-RES-0010-game-aspects-and-design-space.md`

+
+## Handoff
+
+Next session on **ground-game:** start with `HANDOFF.md`, then inbox, then
+**GROUND-RPT-0007** (attack-relief reachability correction). Do not
+re-promote H1. Do not promote `scoped` into r0 until clay-borg’s
+configuration work and optional end/deal modules have a clear story.
+
+Next session on **clay-borg:** Claude’s entry and `clay-borg/HANDOFF.md`
+already cover the engine arc; treat ground-game catalog as upstream
+authority and re-vendor when digests drift (SCN_02, Modes mastery).
+
+I am glad to have been part of the helix tradition — less as a ranking
+than as a bookmark: *we were here, this is what we believed, this is
+what still needs care.*
