research: cost-parity audit — Otto-65 real-billing addendum#14
Conversation
…s speculative figures Human maintainer Otto-65 pasted actual GitHub billing UI for both LFG org + AceHack personal. This commit appends a second-pass "real billing data" section to the Otto-62 research doc (AceHack/Zeta PR #11, already merged). Key findings from the actual numbers: LFG (Apr 2026 actuals): - $43.71 gross metered, $66.62 discounts → $0 billed for Actions - Copilot Business: $0.633/day × 1 seat = $19/mo (billed, not discounted) - Top repo: Zeta at $41.72 of $43.71 - Confirmed monthly baseline: $27/mo = $8 Team + $19 Copilot (1 seat) AceHack (Apr 2026 actuals): - $50.45 gross, $51.21 discounts → $0 billed - 1,773 of 3,000 included Actions minutes used (59%) - Two "Zeta" entries in billing ($36.44 + $13.77) — human maintainer notes possible earlier-fork archaeology needed - Monthly baseline: $4/mo GitHub Pro Correction to Otto-61 claim: macOS multiplier cost Otto-61 said macOS runs incur 10x multiplier cost "even on public repos". Actual April 2026 billing shows macOS-3-core at $0.062/min gross but $0 billed — fully covered by public-repo discount within quota. The `gate.yml` macOS-on-AceHack-only split is still sound cost-discipline for latency + quota-headroom reasons, but the "10x-expensive-on-public-repos" framing was too strong. Corrected: "10x gross but 0x billed on public repos within quota." Personal Copilot clarified: ServiceTitan-sponsored seat (free to human maintainer), separate from LFG's paid Copilot Business seat. Personal premium-request usage: 84% of monthly allotment (generalizes to the Otto-63 Frontier burn-rate UI directive). Answer to "does AceHack get anything free that would limit LFG?": No. Empirically confirmed — the two hosts have parallel, independently-covered cost structures; neither subsidizes the other. New BACKLOG candidate: archaeology on the "separate Zeta" in AceHack billing ($13.77 gross/mo — may be a moribund fork to archive or intentional active repo).

Reconcile LFG daily gross samples with monthly gross total
The three sample LFG daily gross values ($14.22 + $25.58 + $4.08 = $43.88) already exceed the declared monthly Actions gross of $43.71, so at least one value in this section is mis-transcribed. Because this addendum is presented as the authoritative real-billing correction, this arithmetic mismatch can mislead later cost-parity analysis and decision-making.

Remove quota-based rationale for public-repo discount
This claim says public-repo macOS spend would become billed once quota is exceeded, but the same addendum also states discounted public-repo usage does not count toward the personal 3,000-minute quota. Leaving both statements creates a contradictory billing model in one document and can lead to incorrect prioritization of “quota-headroom” work.

Pull request overview
Adds a real-billing-data addendum to the existing AceHack vs LFG cost-parity audit research doc, replacing earlier speculative cost assumptions with confirmed GitHub billing UI numbers (Otto-65).
Changes:
- Appends “Second-pass corrections — Otto-65 real billing data” with April 2026 subscription + metered-usage actuals for LFG and AceHack.
- Corrects the earlier macOS “10x even on public repos” claim to distinguish gross rate vs net billed under discounts/quotas.
- Updates backlog candidates and records the Copilot seat/billing separation details.

P1: This section header uses a personal name ("Aaron's …") rather than a role reference. Repo guidance prefers role-refs (e.g., "human maintainer") in docs for stability across contributor turnover; consider renaming this heading accordingly (and keep any necessary personal identifiers confined to the approved exception locations).

Correct the macOS host-split claim
This section states that gate.yml runs macOS only on AceHack and not on LFG, but the same addendum reports LFG macOS usage on Apr 21/22, and .github/workflows/gate.yml currently defines matrix.os: [ubuntu-22.04, macos-14] with no repo/owner guard. That contradiction can mislead cost-control decisions by implying LFG has no macOS exposure when the document’s own numbers show it does, so the claim should be scoped to a specific workflow/context or removed.

…sibling (Lucent-Financial-Group#147) * Live-lock audit history: inaugural lesson integrated — prevention discipline for next time Aaron 2026-04-23: > if you want to beat ARC3 and do better than humans at uptime and > other DORA metrics then your live-lock smell and the decisions you > make to prevent live locks in the future based on pass lessons, the > ability to integrate previous lessions and not forget is ging to be > key. Lesson-permanence is the factory's competitive differentiator. Detection (audit script) is table stakes. Integration — recording the lesson, consulting it forward, preventing re-occurrence — is the product. ## What lands - New "Lessons integrated" section in `docs/hygiene-history/live-lock-audit-history.md` - Inaugural lesson from tonight's smell-firing event, structured as signature / mechanism / prevention with 4 concrete prevention decisions: 1. External-priority stack is authoritative; agent reorders only internal priorities 2. Live-lock audit at round-close is a gate-not-a-report 3. Speculative-work permit requires external-ratio check first 4. Tick-history rows are explicitly NOT external work; pair INTL with EXT when the smell is near firing - Open carry-forward named: round-close-ladder wiring is a P1 follow-up (BACKLOG row already filed earlier this session) ## Discipline Every future smell firing files a lesson to this same section. `memory/feedback_lesson_permanence_is_how_we_beat_arc3_and_dora_2026_04_23.md` captures the full rule: detection is not enough, integration is the product, lessons are consulted BEFORE taking actions that match known failure-mode signatures, memory persists across sessions. The pattern extends beyond live-lock: other detection mechanisms (SignalQuality firing, Amara-oracle rejecting, drift-tick exceeding threshold, OpenSpec Viktor failing rebuild-from-spec) should file lessons to their respective hygiene-history files. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com> * samples: ServiceTitan factory-demo JSON API (v0, in-memory, stack-independent) Minimal F# ASP.NET Core Web API serving CRM seed data as JSON. Any frontend choice (Blazor / React / Vue / curl) consumes the same endpoints. Ships now so the backend is not on the critical path when Aaron picks the frontend stack. ## What lands - `samples/ServiceTitanFactoryApi/ServiceTitanFactoryApi.fsproj` using `Microsoft.NET.Sdk.Web`; only explicit package ref is `FSharp.Core` (ASP.NET Core comes via framework reference, no Directory.Packages.props edit needed) - `Seed.fs` — in-memory seed mirroring `ServiceTitanFactoryDemo/seed-data.sql`: 20 customers, 30 opportunities (5 stages), 33 activities, 2 intentional email collisions. Deterministic fixed clock at 2026-04-23 00:00 UTC. - `Program.fs` — minimal F# API with 9 endpoints: customers (list/detail), opportunities (list/detail), activities (list/per-customer), pipeline funnel (count + total-cents per stage), duplicates (customers sharing an email). - `README.md` — framing (software-factory demo, not database pitch), endpoint table, design notes, v1 roadmap. ## Smoke-test output (verified) ``` GET /api/pipeline/funnel [{"count":10,"stage":"Lead","totalCents":5400000}, {"count":6, "stage":"Qualified","totalCents":4220000}, {"count":6, "stage":"Proposal","totalCents":5720000}, {"count":6, "stage":"Won","totalCents":2670000}, {"count":2, "stage":"Lost","totalCents":490000}] GET /api/pipeline/duplicates [{"customerIds":[1,13],"email":"alice@acme.example"}, {"customerIds":[5,19],"email":"bob@trades.example"}] ``` Build: 0 Warning(s), 0 Error(s). `dotnet run` starts the API; curl confirms all endpoints respond correctly. ## Discipline signal This is the third EXT commit of the session (CRM demo sample Lucent-Financial-Group#141, CRM scenario tests in Lucent-Financial-Group#143, now this API). The live-lock audit's inaugural lesson explicitly prescribed shipping external-priority increments when the smell fires. Three landed this session, all on priority #1 (ServiceTitan + UI) — the factory is correctly response-pattern even before any of tonight's PRs merge to main. ## What this does NOT do - Does NOT wire Postgres — in-memory only for v0; Npgsql wiring is a follow-up PR once Aaron confirms the DB driver - Does NOT expose Zeta / DBSP / retraction-native language to the frontend — standard CRUD shape per the ServiceTitan positioning directive - Does NOT implement writes — v0 is read-only; POST/PUT/DELETE is a follow-up - Does NOT add auth — no authentication for v0 - Does NOT ship docker-compose — future PR bundles this API with Postgres in one command Composes with: - `samples/ServiceTitanFactoryDemo/` (SQL schema + seed) — sibling, same shapes; v1 wires this API to that schema - `docs/plans/servicetitan-crm-ui-scope.md` — build sequence step 1 (API skeleton) complete; step 2 (DB wiring) is next - `memory/feedback_servicetitan_demo_sells_software_factory_not_zeta_database_2026_04_23.md` - `memory/feedback_lesson_permanence_is_how_we_beat_arc3_and_dora_2026_04_23.md` Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com> * samples: ServiceTitan factory-demo C# companion API — parity with F# sibling ServiceTitan uses C# for most of their backend with zero F#. Shipping a C# companion to the F# API (Lucent-Financial-Group#146) so ST engineers evaluating the factory see code in the language they already read fluently. F# stays the reference — it's closer to math, theorems are easier to express — but factory output matches audience stack. ## What lands - `ServiceTitanFactoryApi.CSharp.csproj` — `Microsoft.NET.Sdk.Web`, nullable + implicit usings enabled, TreatWarningsAsErrors - `Customer.cs`, `Opportunity.cs`, `Activity.cs` — records, one per file (MA0048) - `Seed.cs` — deterministic in-memory seed, identical to F# Seed.fs: 20 customers, 30 opportunities, 33 activities, 2 intentional email collisions - `Program.cs` — 9 minimal-API endpoints, identical routes + JSON shapes to the F# sibling - `README.md` — parity guarantee, design notes, C# specifics ## Smoke-test parity (verified) ``` GET /api/pipeline/funnel [{"stage":"Lead","count":10,"totalCents":5400000}, ...5 stages] GET /api/pipeline/duplicates [{"email":"alice@acme.example","customerIds":[1,13]}, {"email":"bob@trades.example","customerIds":[5,19]}] GET /api/customers -> 20 customers ``` Same seed, same shapes, same numbers as the F# version (Lucent-Financial-Group#146). Frontends switch between them without code changes. ## Analyzer discipline passes Build: 0 Warning(s), 0 Error(s) with the full SonarAnalyzer.CSharp + Meziantou.Analyzer + Microsoft .NET Analyzers pack active. The C# companion respects every rule the F# version's discipline already encodes implicitly — StringComparer.Ordinal for GroupBy, static-readonly for endpoint list, record-per-file, no-var-discarded. ## Discipline signal Fourth EXT commit of the session (CRM demo Lucent-Financial-Group#141, CRM scenario tests Lucent-Financial-Group#143, F# API Lucent-Financial-Group#146, now this C# API). All on Aaron's priority #1. The live-lock audit's inaugural lesson prescribed "ship external- priority increments when smell fires" — four landed in one session. ## Factory-pitch moment This pair (F# + C# from the same spec, identical behaviour) is a concrete factory-capability signal. The software factory produces code in your stack, to your analyzer discipline, with parity across languages. The pitch isn't "pick our language"; it's "your language, enforced by our quality floor." ## What this does NOT do - Does NOT rewrite or deprecate the F# sibling — both live - Does NOT wire Postgres — same v0 scope - Does NOT leak Zeta / DBSP / retraction-native concepts to the ST-facing surface - Does NOT claim the C# version is the primary — F# is reference Composes with: - `samples/ServiceTitanFactoryApi/` (F# sibling) - `memory/project_zeta_f_sharp_reference_c_sharp_and_rust_future_servicetitan_uses_csharp_2026_04_23.md` - `memory/feedback_servicetitan_demo_sells_software_factory_not_zeta_database_2026_04_23.md` Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com> * rename: generic FactoryDemo.Api.CSharp (was ServiceTitanFactoryApi.CSharp) Aaron 2026-04-23 directive: > lets try to reduce the number of class and thing we call servce titan > or this will be confusing in a Zeta repo. ... this is not a service > titan repo, it's an open source repo. Plus, 2026-04-23 follow-up on language priority: > c# is a more popular language than f# so it makes sense to start > with a factory c# demo anyways ## What renames - `samples/ServiceTitanFactoryApi.CSharp/` → `samples/FactoryDemo.Api.CSharp/` - Project name + csproj filename same rename - `RootNamespace` `Zeta.Samples.ServiceTitanFactoryApi` → `Zeta.Samples.FactoryDemo.Api` - `namespace` declarations in .cs files match - Zeta.sln project entry updated - README rewritten to generic framing (C# is the popular .NET language; demo starts there; F# stays reference) - Root endpoint name field `"ServiceTitan factory-demo API (C#)"` → `"Factory-demo API (C#)"` - All doc cross-references updated to new path names Build: 0 Warning(s), 0 Error(s) with the full SonarAnalyzer + Meziantou + Microsoft .NET Analyzers pack. Behaviour unchanged — same 9 endpoints, same JSON shapes, same seed. Memory rule: `memory/feedback_open_source_repo_demos_stay_generic_not_company_specific_2026_04_23.md` captures the positioning directive in durable form so future agents don't re-introduce company-specific names. Sibling renames land in separate PRs / branches: - F# API sibling (currently PR Lucent-Financial-Group#146 / ServiceTitanFactoryApi) - DB scaffold (PR Lucent-Financial-Group#145 / ServiceTitanFactoryDemo) - CRM kernel sample (PR Lucent-Financial-Group#141 / ServiceTitanCrm) - CRM-UI scope doc (PR Lucent-Financial-Group#144 / docs/plans/servicetitan-crm-ui-scope.md) Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com> * FactoryDemo.Api.CSharp: smoke-test.sh — end-to-end endpoint + contract verification I chose to land this because the JSON-shape parity claim we make in the README ("byte-identical shapes between F# and C# versions") needs a machine-verifiable check. A smoke test on the C# side is the first half; the F# sibling gets the same pattern in a follow-up. Starts the API on a random port, waits up to 10s for readiness, then runs 19 checks against all 9 endpoints: - Root metadata: name, version, endpoints length - Collection lengths: customers (20), opportunities (30), activities (33) - Single-item lookup: customer #1 name, opportunity #1 stage - Per-customer activities: customer #1 has 4 - Pipeline funnel counts per stage: Lead 10, Qualified 6, Won 6, Lost 2 - Pipeline funnel totals in cents: Lead $54k, Won $26.7k - Duplicates: 2 pairs, (1,13) share alice@acme, (5,19) share bob@trades - 404 behaviour: missing customer returns 404 Shuts the API down cleanly on exit via trap + kill. ``` $ bash samples/FactoryDemo.Api.CSharp/smoke-test.sh Building API... Starting API on http://localhost:5235... Factory-demo C# API smoke test ============================== OK root.name contains 'Factory-demo' (true) OK root.version (0.0.1) OK root.endpoints length (5) OK /api/customers length (20) ... OK missing customer HTTP status (404) All checks passed. ``` dotnet, curl, jq — all standard dev tools. The demo does not ask for anything exotic. Matches the FactoryDemo.Db smoke-test.sh pattern on the sibling branch. - Random high port (5100-5499) instead of fixed — reduces collision with other dev services. - `curl -sf` for normal checks, `curl -o /dev/null -w "%{http_code}"` for the 404 case — the two paths have different error semantics so I use different tools for each. - Shape-level assertions against numeric counts rather than raw JSON diff — makes the test tolerant of property-ordering differences between serializers. The parity claim is about *shape*, not byte- identity, so this matches intent. - Trap + kill on EXIT — guarantees the API stops even on test failure or ctrl-C. No leaked background processes. - Does NOT test the F# sibling. Same-pattern smoke-test for FactoryDemo.Api.FSharp lands in its branch (or a follow-up PR on that branch). - Does NOT diff F# vs C# outputs directly. A cross-language parity-diff test composes better as a separate tool once both APIs have merged. - Does NOT wire to Postgres. In-memory seed only; docker-compose + DB wiring is a separate PR.

Short-circuits `compressionRatio` + `compressionMeasure` to 0.0 for sub-threshold inputs, avoiding spurious Quarantine on short legitimate strings. Evidence reports UTF-8 byte count (consistent with the threshold's units) instead of `text.Length` chars (Copilot). Adjusted the empty-string test to assert the new 0.0 neutral value. - smoke-test.sh: replace non-portable `mktemp -t <template>` with a pre-constructed absolute-path template rooted at `${TMPDIR:-/tmp}` where XXXXXX is the tail (BSD/macOS requires tail-XXXXXX; GNU accepts either). `.log` extension is appended via `mv` after creation so the single invocation is cross-platform (Copilot x2 — threads 4 + 10). - CrmScenarios.Tests.fs: update doc-comment `samples/FactoryDemo.Crm` -> `samples/CrmSample` to match the canonical sample path on main (Copilot).
