From cdac1b38f92a4e02236587a30cf811b6d6aa0caa Mon Sep 17 00:00:00 2001 From: pm-1 Date: Sat, 6 Jun 2026 11:25:46 -0700 Subject: [PATCH 1/4] docs(sprints): publish sprint 2492 PM plan Theory-of-Constraints sequencing: install-path readiness (publishConfig flip + protocol-freeze CI gate) is the new trunk; vendor-directory submissions and the Cursor forum reply land in days 9-14 once @domscribe/mcp@1.0.0 is publicly installable. Adopts PE RFC 0003's falsifier (any of three branches missing fails the sprint) and inherits DOP's 2026-07-10 falsifier.

PE RFC 0003 amends RFC 0001's Alt A rejection and supersedes RFC 0002's commitment #2: ship v1 against current `@domscribe/core` schemas, defer the package extraction to a trigger-driven follow-on (#32), and substitute a `protocol:freeze-check` CI gate for the package boundary. PE also surfaces a one-line publish-blocker — `packages/domscribe-mcp/package.json` has `publishConfig.access = restricted` while every advertised IDE config tells users to `npx -y @domscribe/mcp` — and sequences the sprint around fixing that first. This thesis is DOP's bet (vendor adoption) + PE's sequencing constraint (install path must be real before submissions go out). Sprint 2491's drafts (#40 publish prep, #41 docs, #42 telemetry Worker) are work-banked and rolled forward. + +## Capacity + +- 2 staff-swe copies × 40h/sprint = **80h total** +- Plan: ~37h (A) + ~36h (B) = **~73h (91% of capacity)**. Tight ceiling — 7h slack. Mitigated by ~10h of carried-forward draft work in #40 / #41 / #42. + +## Prioritization framework + +**Theory of Constraints,** same as sprint 2491. The bottleneck is dependency-driven, not effort-driven: the install path (`publishConfig` flip + freeze gate) is the new trunk that every vendor submission depends on, and the vendor submissions are the artifact the DOP falsifier reads. ToC sequences correctly — protect the trunk, then unblock the bet. RICE would mis-rank: the publishConfig flip has trivial "effort" and devastating "impact when missing," which collapses RICE's information content; ToC names the dependency explicitly. + +## Plan + +The walker hard-caps the fanout at 2 staff-swe tasks.

Re-activates when either (a) ≥1 non-author npm package declares `@domscribe/core` as a wire-schema dependency, or (b) ≥10 weekly-active relay sessions via opt-in telemetry. The substitution is the `protocol:freeze-check` CI gate in T1. +- **FrameworkAdapter public SDK** — DOP/RFC 0001 explicit deferral; concentrates surface area at the wrong layer this sprint. +- **Svelte / Astro adapters** — DOP memo opportunity cost; vendor energy first. +- **Domscribe Cloud / hosted SaaS** — DOP explicit rejection (Vercel/Linear/Replit house advantage). +- **Transport-neutral RCP bindings (gRPC/JSON-RPC)** — RFC 0001 prior rejection; sprint 2492 does not change the calculus. +- **`docs/architecture.md` seven-decisions doc** — RFC 0001 follow-on; RFCs remain canonical record. +- **Outreach to directory maintainers for expedited review** — out-of-scope per #46 acceptance; if a submission is stuck >5 business days, surface to Kaushik (separate decision). + +## Won't-fix + +- **None recommended this sprint.** PR #30 (MseeP.ai badge) remains recommended-for-Kaushik-close — PM does not close PRs it didn't author. No other open issues warrant won't-fix classification given the sprint thesis is single-focus and the rest of the backlog is sleeping. + +## Plan falsifier + +By 2026-06-26 sprint close, **all of:** (a) `@domscribe/mcp@1.0.0` published with `access: public` and `npx -y @domscribe/mcp` verified working from a non-author install (T1 + T5); (b) RCP v1.0 tag stamped with snake_case canonical names + `SourcePosition` required + `docs/rcp/v1.md` live + `protocol:freeze-check` CI gate green (T2 + T3 + T4); (c) all four vendor-directory submissions filed and the `forum.cursor.com/t/146166` reply PR-reviewed and posted (T7 + T8 + T9). **Any of three slipping → PE RFC 0003's falsifier is missed and DOP's 2026-07-10 falsifier becomes structurally unmeetable** — escalate to Kaushik before re-cutting. This is RFC 0003's falsifier transcribed; the PM plan adopts it intentionally because the technical and strategic falsifiers converge this sprint. + +**Plan-level falsifier (PM-specific):** if at mid-sprint check (2026-06-19, day 7) T1 (publishConfig flip + freeze gate) has not merged, the plan is wrong-shaped — the install-path trunk is supposed to land day 1–3, not day 7. Replan immediately: cut T9 (forum reply) and one of the four submissions to sprint 2493 to free capacity for landing T1–T5. + +## Replanning triggers + +1. **T1 not merged by day 3 (2026-06-15)** → escalate to Kaushik. Preferred: pair-program the freeze gate (staff-swe-2 borrows 4h from T6 telemetry to land the script). Last-resort: ship v1.0 with the publishConfig flip alone, defer the freeze gate to sprint 2493 — accepting the procedural risk RFC 0001 warned about for 2 weeks. +2. **Cursor MCP directory submission process changes mid-sprint or requires assets we can't produce in-house** (e.g., demo video > 30s requiring polished UI) → swap T8 priority order so Cline/Continue/Codex file first; Cursor submission slips to sprint 2493. DOP falsifier branch (a) still reachable via Cline. +3. **Tool-rename (T2) alias resolution fails at SDK registration layer** (RFC 0002 risk #1) → block T5 publish; do not ship partial v1. Either fix at SDK layer or invert position (ship v1.0 with dotted-canonical, snake_case as aliases — costs the positioning argument but preserves shipping). +4. **WebMCP full public spec drops mid-sprint with build-time AST instrumentation** → escalate to Kaushik immediately. The "complement at a different layer" framing breaks; entire sprint thesis may be invalid and DOP/PE paths re-open. This was tracked in 2491 too — re-verify around 2026-09-01 per DOP memo. +5. **Telemetry verification install yields zero sessions** → instrumentation is broken, not the bet. Block T5 release-post; debug `npx domscribe init` prompt UX. Same disposition as sprint 2491 trigger #5. +6. **Cursor forum thread `/t/146166` has gone cold (verified at sprint kickoff and again at day 7)** — flagged by DOP as a memo-level uncertainty. If thread is dead, T9 still ships but its DOP falsifier weight collapses; we lean harder on directory submissions (T8). + +## Risks + +- **Tight capacity ceiling (91%).** 7h slack vs. 12.5h in sprint 2491. Mitigated by carried-forward drafts (#40 / #41 / #42) banking ~10h of work; risked by the new install-path issue surfacing additional CI fragility once protocol-freeze starts running on real PRs. +- **Documentation-versioned protocol is a known structural risk** (RFC 0001's original argument against Alt A). Procedural mitigation via `protocol:freeze-check` is fragile until extraction-trigger fires. RFC 0003 §counter-argument names this explicitly; we are accepting it for one quarter. +- **Vendor directory review windows are outside the team's control.** DOP falsifier branch (a) — directory acceptance — may not resolve in-sprint. Mitigated by filing all four submissions and treating "submissions filed" as in-scope, "acceptance" as out-of-scope. +- **Customer-voice gap persists** (Gmail still denied; DOP memo open risk carried forward from sprint 2491). If Cursor forum thread is thin and the four submissions stall, sprint 2493 starts with no fresh customer-voice signal. Pre-grant Gmail before sprint 2493 kickoff.
