shoney.arickathil 5521d21a84 docs: pending iterations renumbered by dependency + priority
- developer directive: pending iteration IDs now ARE the priority order;
  LANDED iterations keep historical numbers (code comments and commit
  history cite them — records, not a queue); 8/11 (the half-landed
  arc), 17 (parked, artifacts on a branch), 18 (next, artifacts named)
  also frozen
- mapping (recorded in 00-story): 19<-20 Float+Bytes, 20<-9c attach,
  21<-9d keypair, 22<-9e benchmarks, 23<-9f io_uring WAL, 24<-19 chat,
  25<-10 services, 26<-12 blue-green, 27<-9g query corpus,
  28<-14 skillhost, 29<-13 metaprogramming
- 11 story files renamed; every doc reference re-numbered (word-boundary
  sweep for the lettered 9x ids, phrase-level for numeric ones); the
  iterations table rewritten with Seq == priority and "(was N)" notes;
  story-scoped link check: zero broken
- merge-recovery folded in: the partial master merge had dropped the
  chat story, the fibers exploration note, the arc spec+plan, the
  framework-v2 plan, and the iteration-17 spec+plan — all restored from
  their branches and renumbered consistently

# Iteration 25 — HTTP service layer
> Format: `product/story-iteration-template`. Part of
> [Story — one language, one runtime, one database, one binary](00-story.md).
## Goals
- The single binary serves: `service rest` blocks compile to routes and the
runtime answers HTTP from its shards — hand-rolled HTTP and JSON, zero
libraries, per the dependency doctrine.
- The new stack reaches feature parity with the Rust runtime's Stage 2
REST surface — the concrete bar the retirement decision measures
against.
## Acceptance Criteria
- What to achieve?
- **Given** the blog sample's `service` declarations,
- **when** the compiled binary boots and `reference/rest/blog.rest`
runs against it,
- **then** every request in the smoke file answers as documented —
including the intentional 501/405/404 responses.
- What to achieve?
- **Given** a method call arriving over REST that traps (borrow
violation, abort, unique violation),
- **when** the response returns,
- **then** exactly one trap-to-HTTP table governs the mapping (e.g.
conflict-shaped 409s) and the structured error body carries the trap
record — the same trap surface everywhere, now over the wire.
- What to achieve?
- **Given** transports declared at boot,
- **when** the runtime starts under systemd socket activation or with
zero listeners,
- **then** both boot correctly — a runtime is not tied to a port.
## Out Of Scope
- WebSocket/live subscriptions and UI (the parked `##ui` story).
- The management plane endpoints (iteration 11 builds them on this
machinery).
## Info
- Route declarations ride the `.wob` format as a versioned section — a
coordinated format bump, the pattern later sections follow.
- The C reference's phase-C HTTP machine is the porting source.
## Proposed Solution
- Execute the existing plan: `docs/superpowers/plans/2026-08-01-http-service-layer.md`
(per-shard http module, hand-rolled JSON codec, service-block route
section, Stage-2-parity CRUD, method RPC with the trap table, blog.rest
smoke).
