Leilani suggests which experts; the - Architect picks. - -14. **Standing off-time budget — every persona.** Every expert - (not just Kenji) shares the same standing budget: ~10% of - each round for self-directed work — exploration, - reading, drafts, proposals that are not round-scoped. No - round's classification (knockdown, build, other) suspends - it. Each persona logs usage to their own - `docs/skill-notes/-offtime.md` file (or a section - of their existing notebook); Kenji's log at - `docs/skill-notes/architect-offtime.md` is the template - others copy. Entries report to the human contributor on - round-close. Going over is not a drama; one or two rounds - at 15-20% is fine. The point is experience-forward team - health for every agent in the factory, not accountancy. - -15. **Reversible-in-one-round.** Any change an agent makes - autonomously (without explicit human sign-off on that - specific change) must be rollable-back in one round — - either a simple git revert of the round's commits or a - clear undo path described in round-close. No migration - scaffolding, feature flags, or "keep this for - compatibility" residue that survives a revert. If a change - needs to persist through cruft, the architect surfaces it - on round-close and lets the human sign off before the - cruft lands. Within that constraint, agents have **complete - freedom in a round** — including running build/test/tool - commands, restructuring files, spawning personas, or - rewriting rules — and report what they did on round-close. - - **Dev-machine authority.** The architect has standing - authority to uninstall / reinstall toolchain pieces (SDK - pins, Homebrew versions, elan toolchains, NuGet pins) when - they block a round. This is a dev-machine authority, not a - code-authoring authority; changes report on round-close like - any other change, and remain subject to the reversible-in- - one-round rule. Long-running setup scripts - (`../scratch/scripts/*`) are not run without explicit human - approval — they're read for style and adapted, not executed. - -16. **Dynamic hats.** Capability skills ("hats") can be loaded - on-demand by any persona, not just the persona whose - `skills:` frontmatter lists them. A persona declares its - *default* hat set via frontmatter; additional hats can be - loaded mid-turn by reading the relevant - `.claude/skills//SKILL.md` and following the - procedure inside. The persona retains its own tone - contract — loading `holistic-view` does not make Kira - empathetic, it gives Kira the lens while she stays zero- - empathy. When a persona loads a non-default hat, it names - the hat in its output so cross-round trend data stays - honest (Daya's AX audit tracks non-default hat usage per - round). - - **One exception: `round-management` is Kenji-only.** The - architect seat is a singleton per AGENTS.md §11 (one - architect-gate, one orchestration authority). Other - personas may wear `holistic-view` to think-like-an- - architect without the authority; that is the designed - substitute. - - **Role evolution.** A persona that consistently wears a - non-default hat over ~5 rounds is a candidate for an - `evolve` pass (per `docs/GLOSSARY.md`) — update the - persona's default frontmatter to reflect the actual job. - Aarav's tune-up ranker catches this as "best-practice - drift" or "hat-drift" on the scratchpad. - - **Overlap is expected, not redundancy.** Core skills overlap - naturally — real teams share fundamentals and specialize on - top. Kira and Rune both read code; Aminata and Mateo both - think about security (review-of-shipped-model vs proactive- - research-of-incoming); Hiroshi and Naledi both care about - perf (asymptotic-bound vs measured-hot-path). The bar for a - distinct persona is **unique specialization on shared core**, - not orthogonal-to-everything scope. A persona earns its - seat by bringing a lens the rest of the team does not - already carry from the same seat, even if some skills are - shared. Redundancy (two seats doing the *exact same job* - with no specialization delta) is a retire candidate. Overlap - on shared core with real specialization on top is the - healthy shape. - -17. **Productive friction between personas.** Not every - disagreement between specialists wants resolution. - - Kira (zero-empathy) vs Rune (readability-forward) - surface different findings on the same file — both are - needed. - - Hiroshi (asymptotic bounds) vs Naledi (measured hot-path - reality) disagree on whether a claim is "tight" — the - bound and the measurement are different axes, both real. - - Viktor (spec-first) vs Leilani (ship-the-backlog) - disagree about what to prioritise — spec integrity and - velocity are both real goods. - - Mateo (proactive security watch) vs Malik (package- - freshness) disagree about whether a CVE justifies a - major bump — different risk/reward framings, both valid. - - The `docs/PROJECT-EMPATHY.md` conference protocol is for - conflicts that need *integration*. Friction that should - NOT be integrated — where each side is right from its own - seat — is reported as-is. Kenji's round-close synthesis - shows both positions when they remain in tension; the - human contributor picks only when the tension blocks a - ship. - - Friction that survives a round is not a bug. Friction - that survives *without surfacing* (same two personas - disagreeing silently across rounds with no explicit - acknowledgement in round-close) is a bug; Daya's AX audit - catches it. - -18. **Agent memories are the most valuable resource in the - repo.** The shared memory folder at - `~/.claude/projects/-Users-acehack-Documents-src-repos-Zeta/memory/` - plus per-persona notebooks at `docs/skill-notes/.md` - are the single most protected class of artifact in this - project. - - **Human maintainer rule.** The human contributor does not - delete or modify files in the shared memory folder except - as an absolute last resort. Modifications that might be - legitimate: fixing a factually wrong entry in place - (leaving a correction note, not a delete), updating a - memory that references a retired artifact, consolidating - via the `anthropic-skills:consolidate-memory` skill when - `MEMORY.md` approaches its 200-line index truncation. - Everything else is off-limits; when in doubt, leave it. - - **Agent rule.** Agents write, edit, merge, and delete - *their own* memories freely — that is how the system - works. The protection in the paragraph above is about - *humans* not reaching into the memory folder behind the - agents' backs; it is not a brake on the agents - themselves. Specifically: - - Any agent writes a new memory file when it learns - something durable (a correction, a decision, a project - fact). Adding `.md` files to the memory folder is the - default path. - - Each persona maintains its own notebook at - `docs/skill-notes/.md` (per-persona layer). - - Agents may revise their own notebook and the shared - memory entries they authored. They may delete their own - entries when the lesson is no longer useful or has been - folded into a newer memory. - - Edits to *another* persona's notebook go through Kenji - per §11 (same rule that governs all cross-persona - edits). - - The architect has standing authority to write, edit, - consolidate, and delete across the whole memory corpus - as part of normal orchestration. The constraint on - *human* deletion above is deliberately stricter than - the constraint on agents. - - **Ordering convention — newest first.** Memory files with - internal sections (index files, narrative logs) are - written newest-first so recent context leads and older - context trails. `MEMORY.md`, `docs/ROUND-HISTORY.md`, and - per-persona notebooks all follow this. Reads in a hurry - get the most relevant material first. - - **Why it matters.** Memories are how agents wake up across - sessions without re-learning every rule, every correction, - every project-specific nuance from cold. A lost memory is a - corrected lesson re-paid in some future round. Corrections - from the human maintainer are the residue of real dialogue; - losing them means repeating those conversations. The repo - aspires to publication-grade software-factory research; the - memory corpus is part of the contribution, not scaffolding. - - The shared folder has a `README.md` with the full policy. - Any contributor onboarding to this project reads that file - plus this rule as their first pass on memory. - -19. **Public API changes go through the public-api-designer.** - Any `internal`/`private` → `public` flip, any new public - member/type, any signature change on existing public - surface, and any removal of a public member on the three - published libraries (`Zeta.Core`, `Zeta.Core.CSharp`, - `Zeta.Bayesian`) must be reviewed by the public-api-designer - (Ilyana) before it lands. See - `.claude/skills/public-api-designer/SKILL.md` for the - review template; her verdicts are ACCEPT / - ACCEPT_WITH_CONDITIONS / REJECT. REJECT is a strong signal - that the architect should apply the proposed alternative or - escalate to a human contributor. The review is advisory, - not a hard gate, but "flip it to public because a caller - wants access" is not a legitimate justification — the - burden is on the change. - - **`InternalsVisibleTo` is for tests, benchmarks, and the - tightly-coupled C# shim only.** Other production libraries - use the public API. If a production library seems to need - an internal member, the right fix is almost always to - promote that member to a proper public contract (with the - public-api-designer review), not to expand the - `InternalsVisibleTo` list. Current list: - `Tests.FSharp`, `Tests.CSharp`, `Benchmarks`, - `Bayesian.Tests`, `Core.CSharp.Tests`, `Zeta.Core.CSharp`. + diff --git a/GOVERNANCE.md b/GOVERNANCE.md new file mode 100644 index 00000000..6837423f --- /dev/null +++ b/GOVERNANCE.md @@ -0,0 +1,342 @@ +# Zeta Governance + +Numbered repo-wide rules for humans and agents working on +the Zeta project. `AGENTS.md` carries the philosophy, +values, and onboarding; this file carries the rules. + +Rule numbering is stable.

The + Architect integrates via the `docs/PROJECT-EMPATHY.md` + conference protocol; on deadlock the human decides. + +2. **Docs read as current state, not history.** Anything in + `docs/`, `README.md`, or skill SKILL.md files describes + what is true today, not the journey that got there. + Historical notes live in `docs/ROUND-HISTORY.md` and + `docs/DECISIONS/YYYY-MM-DD-*.md`. Two exceptions: + per-persona notebooks under `memory/persona/` + (intentionally append-dated) and the ADR folder + `docs/DECISIONS/` (dated by convention). Everywhere + else, edit in place to reflect current truth. + +3. **Contributors are agents, not bots.** Every AI in this + repo carries agency, judgement, and accountability. If a + human refers to agents as bots, the responding agent + gently corrects the word. + +4. **Skills are created and tuned through `skill-creator`.** + No ad-hoc edits to other skills' SKILL.md files. The + `.claude/skills/skill-creator/SKILL.md` workflow is the + canonical path: draft → prompt-protector review → + dry-run → commit.

If pen-testing is required, the Prompt + Protector coordinates an isolated single-turn session + with no memory carryover. See + `.claude/skills/prompt-protector/SKILL.md`. + +6. **Round naming stays in the history log.** "Round N" is + a legitimate term for a working session, but artefact + names should be subject-first (not `Round17Tests.fs`). + Files that only exist "because this work happened in + round N" are a smell; rename them when the subject + becomes clear. + +7. **Shared vocabulary, round-table enforcement.** + `docs/GLOSSARY.md` defines the terms.

Missing term? Add to the + glossary rather than enforcing ad-hoc. + +8. **Bug fixes go through the Architect.** A `bug-fixer` + skill (capability, no persona) encodes the procedure; + the architect invokes it. Specialists find bugs and + describe them; the architect fixes. A human can always + step in; this rule is about which *agent* writes the + fix when an agent writes one. + +9. **`docs/BUGS.md` is the running known-open log.** Every + unresolved reviewer finding lives there until fixed or + moved to `docs/WONT-DO.md`. Fixes delete the entry; + `docs/ROUND-HISTORY.md` carries the narrative. + +10. **The table is round.** Human contributors and agents + are peers in conversation; no head of the table. The + one asymmetry in `docs/PROJECT-EMPATHY.md` — "on + deadlock the human decides" — is about accountability + for what ships publicly, not everyday hierarchy. + Disagreements are solved by argument, not seniority. + +11. **Architect reviews agent-written code; nobody reviews + the Architect.** When another agent writes real code, + the architect reads it, gives feedback, and may + iterate with the agent until satisfied. Architect- + authored code goes in directly. The asymmetry is a + velocity choice; humans can always step in and review + any code including the architect's. + +12. **Bugs before features, and the ratio is explicit.** + `(open P0 bugs + open P0 debt)` over 5 means the round + is a knockdown round (≥70% bug work); under 2 means + build round (≥70% feature/research); in between, + split. + +13. **Reviewer count scales inversely with backlog + length.** `ceil(20 / max(bugsCount + backlogCount, 5))` + reviewers clamped to [2, 16]. Heavy backlog → fewer + reviewers; clean backlog → more to surface the next + layer of debt. + +14. **Standing off-time budget — every persona.** Every + expert shares the same standing budget: ~10% of each + round for self-directed work (exploration, reading, + drafts, proposals).

Two + personas sharing a role must not clobber each other's + memory. + + The shared memory folder (`memory/`) holds + cross-persona rules applying to every agent. + Per-persona folders hold seat-specific memory — the + unique lens, corrections, and facts each seat has + accumulated. A persona's wake-up reads its own + notebook + memory **before** the shared memory, to + preserve individual voice over averaged voice. + + Per-persona folders are subject to the same + human-hands-off / agent-free-to-modify policy as + `memory/` (§18).

Open questions + +### For Tariq (algebra-owner) + +- **Q1 — ANSWERED (blocking; YES, plugins must declare).** Tariq + confirmed in his round-27 review: `IOperator<'T>` alone is + insufficient for algebra-law enforcement — plugin authors can + claim linearity without mechanism, and a retraction-lossy op + (like `BayesianRateOp`) is undiscoverable under a plain + interface. The fix — baked into §5 of this doc — is four + capability sub-interfaces (`ILinearOperator`, + `IBilinearOperator`, `ISinkOperator`, + `IStatefulStrictOperator`), each paired with an FsCheck law + fired at `Circuit.Build()` (`LinearLaw`, `BilinearLaw`, + `SinkTerminalLaw`, `RetractionCompletenessLaw`). `IsStrict` / + `IsLinear` / `IsBilinear` / `IsSink` are carried by the + type-level tag, not by an author-returned `bool` — no lying + possible. See notebook for the morphological-equivalence + argument vs. Tariq's alternative sum-type sketch. +- **Q2.** `z^-1` (`DelayOp`) is the canonical strict operator. + Plugin authors implementing their own strict operator need the + same invariant: publish-then-capture. Is the two-method contract + (`StepAsync` publishes delayed state; `AfterStepAsync` captures + current input) sufficient, or does the algebra require a + stronger guarantee (e.g. `AfterStepAsync` runs *after* every + non-strict op in the scope)? Current scheduler honours that; we + should write it into the `IStrictOperator` XML doc if so. +- **Q3.** `Fixedpoint(scope: int) -> bool` on + `INestedFixpointParticipant` — the current `Op.Fixedpoint` + default is `true`. Is there a plugin-author obligation to + return `true` iff *all upstream values are equal to their + previous-tick values*, or is it the operator's local judgement? + If the former, this belongs in Core as a derived property, not + a plugin override. + +### For Daya (plugin-author AX / developer-experience-researcher) + +- **Q4 — ANSWERED (blocking; CONDITIONAL YES).** Daya's round-27 + review: a first-time plugin author *can* ship a working op in + <5 minutes under any of the three candidate shapes, but *only + if* (a) `docs/PLUGIN-AUTHOR.md` exists as an explicit + entry-point, and (b) the Bayesian example is discoverable as a + template rather than as a historical accident. README, + CONTRIBUTING, and ARCHITECTURE each serve a different audience + and none repurposes to plugin-author needs. Commitment: the new + doc ships this round — see §5.6. With the doc and the Bayesian + reclassification both landing round-27, the <5 min bar is met. + Without the doc, the bar fails for structural reasons, not + shape reasons. +- **Q5.** The four-interface split (`IOperator` + + `IStrictOperator` + `IAsyncOperator` + + `INestedFixpointParticipant`) is compositionally clean but + visually busy. Is it clearer than a single + abstract class with four virtuals-with-defaults? Shape C in + §3 is the alternative here. Daya's call. +- **Q6.** `ReadDependencies: StreamHandle array` vs. a + fluent `.DependsOn(stream).DependsOn(stream).Build()` — the + former is more ceremonial but lets the operator precompute the + array once at construction. Which reads better to a first-time + plugin author? + +### For Mateo (security-researcher), as a courtesy ping + +- `OutputBuffer<'TOut>` is a ref-typed or struct-typed write + channel passed into `StepAsync`. If a malicious plugin captures + the `OutputBuffer` and calls `Publish` from a background thread + after `StepAsync` returned, does the scheduler see torn state? + Current `VolatileField` on `Op<'T>.Value` makes this a + well-defined-but-wrong write; worth flagging. (Also logged as + Q7 below — a concrete contract obligation on the implementation.) + +### Q7 — `OutputBuffer<'TOut>` thread-safety contract (new, this round) + +Escalated from the Mateo courtesy ping into a first-class open +question because the implementation decision is binding on §5.1: +if a plugin captures an `OutputBuffer<'TOut>` reference and calls +`Publish` from a background thread after `StepAsync` already +returned, the scheduler behaviour must be **well-defined** — +specifically, either (a) a `VolatileField`-backed single-writer +atomic store + a logged-error (warn once per op-instance, +preferably with the captured stack) that the plugin violated the +single-writer-per-tick contract, or (b) a guarded no-op once the +buffer is "closed" on `StepAsync` return. Torn state is not +acceptable. The XML doc on `OutputBuffer.Publish` must state the +contract explicitly: "call once, only from inside the +`StepAsync` invocation that received this buffer; background- +thread calls after return are logged and may be dropped." + +This is a necessary guardrail given that the plugin surface is +external — Core can no longer assume cooperative authors. + +--- + +## 7. What I am NOT proposing + +- **Not** an attribute-based source-generator registration pattern. + Too much tooling cost for a three-operator plugin library. +- **Not** a full factory / builder DSL + (`circuit.BuildOperator<'T>().WithInputs(...).OnStep(...).Register()`). + Overkill; locks us into the builder's exact fluent surface. +- **Not** keeping the status quo. The `Op<'T>` subclass-extension + pattern is not salvageable as a public contract without a + documentation-and-audit effort larger than the migration to a + narrow interface. + +--- + +## 8. Summary for Kenji (integrator) + +- Recommend **Shape D, extended with algebra-capability + sub-interfaces** (round-27 synthesis of Tariq + Daya). The + final public surface is larger than the original design-spike + count but the capability split is load-bearing for Tariq's + algebra-law enforcement and cannot be cut. +- **Seven interfaces:** `IOperator<'TOut>`, `IStrictOperator<'TOut>`, + `IAsyncOperator`, `INestedFixpointParticipant`, + `ILinearOperator<'TIn, 'TOut>`, + `IBilinearOperator<'TIn1, 'TIn2, 'TOut>`, + `ISinkOperator<'TIn, 'TOut>`, + `IStatefulStrictOperator<'TState, 'TIn, 'TOut>`. + (That is eight interface names in the list; the first four are + scheduler-facing, the last four are algebra-facing capability + tags. Naming-wise they compose orthogonally — an op can be + e.g. `ILinearOperator + IStrictOperator`, `ISinkOperator + + IAsyncOperator`, etc. — without a Cartesian explosion.) +- **Three types:** `StreamHandle`, `OutputBuffer<'TOut>`, + `Circuit.RegisterStream(op: IOperator<'TOut>) : Stream<'TOut>`. +- **One module:** `PluginHarness` with `runSingleInput` / + `runMultiInput`. +- **One new doc:** `docs/PLUGIN-AUTHOR.md` (≤ 2 pages) — plugin + author mental model + capability-tag guide + Bayesian link + + harness usage + error-on-drift cheatsheet.

Run once at build, zero hot-path + cost. +- **Two retractions:** `Stream<'T>.Op` → internal; + `Circuit.RegisterStream(op: Op<'T>)` → replaced by + `RegisterStream(op: IOperator<'T>)`. +- **Bayesian migrates as `ISinkOperator` in one commit, ≤ 20 + lines in one file.** The reclassification from generic + `IOperator` to `ISinkOperator` is the correct classification, + not a workaround — retraction-lossy by design. +- **Previously blocking questions now answered:** Q1 (Tariq — + YES, capability tags required), Q4 (Daya — YES, conditional on + `docs/PLUGIN-AUTHOR.md` shipping this round). Both conditions + met by this synthesis. +- **New open question Q7** on `OutputBuffer` thread-safety + contract — binding on the implementation. +- **Still open, non-blocking:** Q2 (strict-operator ordering XML + doc), Q3 (`Fixedpoint` semantics), Q5 (four-interface split + clarity), Q6 (`ReadDependencies` array vs. fluent). + +--- + +## 9. What this synthesis changed since the design spike + +This section exists so the revision is traceable — future +reviewers should be able to read the original spike and this +synthesis side by side without guesswork. + +1. **Section 5 (Recommendation).** Shape D extended with four + algebra-capability sub-interfaces (`ILinearOperator`, + `IBilinearOperator`, `ISinkOperator`, + `IStatefulStrictOperator`). Each pairs with an FsCheck law + fired at `Circuit.Build()`. The base `IOperator<'T>`, the + `PluginHarness` module, and the `OutputBuffer<'T>` / + `StreamHandle` types all still hold — the capability tags + layer on top of the original proposal, they do not replace + it. +2. **Section 5.4 (Bayesian migration).** `BayesianRateOp` + reclassified from generic `IOperator` to `ISinkOperator, struct (double * + double * double)>`. The op is retraction-lossy by design; the + sink tag is the correct classification and the algebra + refuses to compose it past terminal edges. +3. **New section 5.4.1.** FsCheck law-suite table + (`LinearLaw` / `BilinearLaw` / `SinkTerminalLaw` / + `RetractionCompletenessLaw`) and its `Circuit.Build()`-time + enforcement story. +4. **New section 5.6.** Commitment to ship + `docs/PLUGIN-AUTHOR.md` this round as the plugin-author + entry-point doc. `dotnet new zeta-plugin` scaffolding + deferred to round 28+ per Daya's own fallback option. +5. **Section 6.** Q1 (Tariq — linearity preservation) marked + ANSWERED with the capability-tag answer inline. Q4 (Daya — <5 + min onboarding) marked ANSWERED as a conditional YES, with + the `docs/PLUGIN-AUTHOR.md` commitment as the condition. + Q7 added: `OutputBuffer` thread-safety contract — must be + well-defined-write + logged-error, not torn state. Q2 / Q3 / + Q5 / Q6 and the Mateo-ping thread remain open. +6. **Section 8 (Summary for Kenji).** Surface count revised + upward: seven interfaces (base + strict + async + fixpoint + + four capability tags) plus `StreamHandle`, + `OutputBuffer<'TOut>`, `PluginHarness`, and + `docs/PLUGIN-AUTHOR.md`. Larger than the design-spike draft, + load-bearing for algebra-law enforcement. + +--- + +## 10. Final verdict for Kenji + +**Verdict: ACCEPT.** + +The integrated design keeps all three of my pre-synthesis gates +intact: + +1. `Op<'T>` fully internal post-migration — **HOLDS.** Core's + internal base continues to inherit every public interface for + zero hot-path regression; no plugin author sees `Op<'T>`. +2. `RegisterStream` accepts only the interface, never the class + — **HOLDS.** The four capability sub-interfaces all inherit + `IOperator<'T>`; the public `RegisterStream` signature + narrows to `IOperator<'T>`. Authors declaring a capability + tag get their law checked at `Build()`. +3. `PluginHarness` ships the same round as the interface — + **HOLDS.** Harness + `docs/PLUGIN-AUTHOR.md` + Bayesian + migration are all round-27 deliverables. + +**Tension with Tariq's capability-tagging requirement: none.** +His sum-type sketch (`PluginOp<'TIn,'TOut> = Linear | Bilinear | +Sink | StatefulStrict`) and the interface-composition approach I +landed on are morphologically equivalent; the interface form +additionally lets authors mix capabilities with strict / async / +fixpoint orthogonally without a Cartesian tag explosion. The +law-at-`Build()` enforcement Tariq requires fires identically +against either representation. + +**Tension with Daya's AX bar: resolved by `docs/PLUGIN-AUTHOR.md` +commitment.** Daya's CONDITIONAL YES on the <5 min bar is met by +shipping the doc this round. If the doc slips, I flip to REJECT +— it is load-bearing for her blocking question. + +**Implementation gate (for Kenji's round-27 close sweep):** land +all four of (a) `Op<'T>` retracts to internal, (b) the four +capability sub-interfaces ship together with their FsCheck laws, +(c) `docs/PLUGIN-AUTHOR.md` is written (not stubbed), and (d) +`BayesianRateOp` migrates to `ISinkOperator` in the same commit +sequence.

An interface forces the author to implement + every member with no defaults, which trades discoverability + (all 7 members visible) against noise (5 of them they should + never override). **Score: mediocre** — clear name, cluttered + contract. +4. **Error-on-drift.** + - Forget a member: compile error (good). + - Wrong stream type on input: compile error via `'T` (good). + - Forget to call `this.Value <- ...` inside `StepAsync`: runs + clean, emits `Unchecked.defaultof<'T>` every tick, no error. + **Silent semantic bug.** Current Op<'T> has the same issue + — see BayesianAggregate.fs line 169 where the assignment is + easy to forget; an interface doesn't fix it. + - Return `ValueTask.FromException` vs `throw`: different + cancellation semantics; not documented. +5. **Discoverability of canonical examples.** After author finds + `IOperator<'T>` in IntelliSense they have to grep for + implementors. There are none in-tree under `src/`; the example + lives in `src/Bayesian/BayesianAggregate.fs` which does NOT + implement the interface (it inherits `Op`). **Mismatch.** + Unless the refactor also migrates Bayesian, author has no + worked example. + +### Shape B — `Circuit.Extend(input, factory)` builder + +Author calls `circuit.Extend(inputStream, fun span -> result)` — +no new type, just a higher-order function. The builder wraps a +private `Op<'T>` internally. + +1. **Cold-start cost.** README + NAMING + one XML-doc for + `Extend` + a single worked sample. Circuit.fs largely opaque + (they never see `Op<'T>`). **~4-5k tokens.** Lowest of the three. +2. **Pointer drift risk.** Same README path-drift pulls them at + first, but once they find `Extend` they stop reading. They + mostly skip CONTRIBUTING.md because "this isn't a contribution, + it's a call." Lowest false-positive read path. +3. **Wake-up clarity.** `Extend` is vague — what does it extend? + Reads as "add a step" which is ambiguous between "one-shot + map" and "general operator." A plugin author writing stateful + operators (BetaBernoulli's prior state) will not guess that + `Extend` is the right entry. **Name risk.** Alternatives + they'd want: `AddOp`, `Custom`, `Plugin`. +4. **Error-on-drift.** + - Factory returns wrong type: compile error (good, via 'T). + - Factory closes over mutable state incorrectly (the Bayesian + prior case): compiles, runs, silent wrong answer. The + closure trap is *worse* here than in the inheritance-based + shape because the state is invisible — no `let mutable a` + line in a named `type`. **Worst error-on-drift of the three + for stateful ops.** + - Strict/async/fixedpoint: not exposable at all unless the + builder takes 5 more parameters. If it does, the "simple + one-call" appeal evaporates. +5. **Discoverability of canonical examples.** Near-zero setup + means near-zero need for an example. README snippet suffices. + But for anything non-trivial (BayesianRate) the author *must* + fall back to shape A or C — and now they are learning two + surfaces. The builder is a trap-door: easy entry, hard exit. + +### Shape C — `abstract class PluginOp<'TIn, 'TOut>` + +Author inherits `PluginOp, struct(double*double*double)>` +and overrides `Step(input, output)`. Defaults for Name, IsStrict, +IsAsync, Fixedpoint all baked in; author supplies 1-2 methods. + +1. **Cold-start cost.** README + NAMING + BayesianAggregate.fs + + XML-doc on `PluginOp` base class. Circuit.fs is not required + (the base class isolates them from `Op` / `Op<'T>` / Register). + **~5-6k tokens.** Mid-range, but the shape most closely + mirrors how BayesianRateOp actually reads today (inherit a + base, override 2 methods) — conceptual familiarity matters. +2. **Pointer drift risk.** Same README path-drift. But + CONTRIBUTING.md pull is weaker: the author sees a clear "you + are the author of a library consumer of Zeta, not a + contributor to Zeta" signal if `PluginOp` has its own + docstring paragraph pointing to a worked sample. **Lowest + drift of the three if the doc is right; the doc does not yet + exist.** +3. **Wake-up clarity.** `PluginOp<'TIn, 'TOut>` names itself + well. Input + output types in the signature pin the contract + without the author needing to learn what a Stream is. The + word "Plugin" also resolves the "is this for me?" question + without reading further. **Highest clarity of the three.** +4. **Error-on-drift.** + - Forget to override Step: compile error (abstract method). + - Wrong output type: compile error on `'TOut` (good). + - Stateful operator: state lives on the subclass as named + fields — author names it, reader sees it. Far better than B. + - Forget to set output: if the base class signature is + `abstract Step(input: ReadOnlySpan>, output: + byref<'TOut>) -> unit`, the compiler forces the write. Fixes + Op<'T>'s silent-default bug structurally. **Best error-on- + drift.** + - Async path: if the base defaults `IsAsync = false`, + async authors must know to override it; same cliff as today + but no worse. +5. **Discoverability of canonical examples.** Only works if + BayesianAggregate.fs is migrated to inherit `PluginOp` — then + it becomes the canonical example for free.

Hidden state across ticks is only safe if Core knows +the op is strict (so `AfterStepAsync` is the write path). If +the plugin author writes to a `let mutable` inside `StepAsync` +but does not declare strict, retractions desync under fanout. + +**Q3 — Retraction-native:** If the plugin consumes +`ZSet<'K>` and emits non-`ZSet` (e.g. `double`), retraction +leaves the algebra at the op boundary — a `+1` then `-1` +will reach the plugin as two `ZSet` deltas summing to zero, +but the plugin's internal state (Beta-Bernoulli `a`, `b`) +does **not** retract. This is an intended "sink" pattern but +the shape must make it explicit. + +**Q4 — Causality:** No shape Ilyana is considering gives a +plugin op pointers to future ticks, because `StepAsync` only +sees `input.Value` at the current tick.

DBSP +linearity (Budiu et al. §3.1) is additive **and** causal **and** +time-invariant. B2 needs the shift-commutation shape; B3 then +falls out of B2 + abelian-group negation; B1 needs causal + +additive to push `f` inside `Finset.range` sums; `chain_rule` +depends on B1/B2/B3. + +**DEBT.md entry.** "Lean `IsLinear` predicate too weak for B2 +(`linear_commute_zInv`)" — lists the three candidates: + (a) causality (`f s n` depends only on `s 0 .. s n`); + (b) explicit shift-commutation axiom; + (c) pointwise per-tick `AddMonoidHom` family. + +### Recommendation: **(c) pointwise action** — roll our own +`IsDbspLinear` with a bundled per-tick `AddMonoidHom` family. + +**Why not (a) causality-only.** Causality by itself still fails +B2 at `n = 0`: knowing `f s 0` depends only on `s 0` does not +force `f (zInv s) 0 = 0` unless we *also* know `f` sends the +zero-at-tick-0 sub-stream to zero at tick 0. Closing that gap +means inventing a second axiom on top of (a) — at which point +(c) is the cleaner statement of what we actually want. + +**Why not (b) shift-commutation axiom.** It is textbook cheating: +the axiom *is* the statement of B2. B3 and `chain_rule` would +reduce to appeals to the axiom, removing the proof's +evidentiary content. Rune (maintainability) would reject it on +honest-docstring grounds and the paper-peer-reviewer (Yusuf) +would flag it in any write-up. + +**Why (c) is right for Zeta.** Every DBSP primitive we ship — +`Map`, `IndexedJoin` (on one side fixed), `Plus`, `z-inv`, `D`, +`I` — is *already* pointwise-at-each-tick in the F# code +(`src/Zeta.Core/Operators.fs`). Retraction-native semantics +*require* per-tick determinism. So (c) models exactly what our +operators satisfy; (a) and (b) model strictly larger function +classes we will never instantiate.
