ehoandClaude Sonnet 5 a8c7a573fc refactor: move SaveState into debounced-save.ts, delete action-state.ts (RD-14)
RD-12 and RD-13 moved both ActionState consumers into their machines. This
left ActionState with zero users, so this ticket deletes it outright.

SaveState is different. It has two four-way consumers (brief.page.ts and
org-template.page.ts) that still switch on all four cases, so it survives.
It moves into debounced-save.ts, next to createDebouncedSave, the only
function that sets it. Both store imports merge into the existing
debounced-save import line. The doc comments that named ActionState are
reworded, since the type no longer exists. No store's public saveState
signature changes, so brief/ui/ needs no edit.

This completes the phase. Two encodings survive: RemoteData for fetched
data, and each machine's own state union. SaveState stays as an explicitly
justified third encoding, for a separate concern (debounced autosave status)
that the other two do not cover.

# Readable codebase — apply the dashboard pattern to the rest of the app
The dashboard refactor cut `dashboard.page.ts` from 340 lines to 42. It was built as a
**reference implementation**: prove the pattern on one screen, then hold the rest of the app
to the budget it establishes.
This arc applies that result. The full design record, with every measurement and every
rejected alternative, is [`PLAN.md`](PLAN.md). Each ticket below is one commit.
Two findings shape the work:
1. **Pages are already thin** (17 pages, median 88 lines). The remaining bulk sits one layer
down, in organisms.
2. **The worst problem is not size.** `runIfSubmitting` is copy-pasted into 5 components and
must be called by hand after `dispatch`. Forgetting it fails silently. RD-06 fixes two
user-facing bugs that follow from it.
## Session protocol
- **One ticket per session.** Read `CLAUDE.md`, this README, the ticket file, and the
ticket's "Read first" list — then execute. Do not start the next ticket in the same
session.
- The **Decisions** block in each ticket is pre-made. Do not relitigate it. `PLAN.md` records
why, including the alternatives that were rejected and the reasons.
- **Ticket files are written just in time, not all 35 up front.** Writing one means choosing
which decisions and which traps from `PLAN.md` belong in it, so the **supervisor** writes
the ticket file (an Opus-shaped job) immediately before delegating it. The file lands in
that ticket's own commit. Generating all 35 in advance would be speculative — later tickets
are better written once the earlier ones have taught us something.
- **Match the model to the step** (see CLAUDE.md, "Model routing for agent delegation").
Executing a ticket is written for the `developer` agent (Sonnet). Read-only checks go to
`task-runner` (Haiku). Escalate to `planner` (Opus) only if a Decisions block turns out to
be wrong — in which case stop, and fix `PLAN.md` first.
- A ticket ends **GREEN**, with its acceptance criteria checked, its `Status:` set to `done`,
**and its README row updated — all in the same commit as the code.** Never in a follow-up
commit. This is what makes a restart safe: whatever is committed is done, and whatever is
not is not.
- **`Status: done` carries no commit hash**, because a commit cannot contain its own hash. The
commit is recoverable when you need it:
`git log --oneline --diff-filter=A -- docs/project/readable-codebase/RD-NN-*.md`.
- No ticket leaves a check disabled without an inline reason **and** a reference to the
ticket that removes it.
## GREEN (global definition of done)
```bash
npm run ci
```
For any ticket whose "`--full`?" column says yes — it touches a story, an `.mdx`, or
`libs/shared/src/ui/**` — additionally:
```bash
npm run ci --full
```
`npm run ci` does **not** build Storybook. Only `--full` does, and a broken `.mdx` story
import is invisible until it runs. RD-27 in particular must not be pushed without it.
## Recovery after a restart
A fresh session with no context needs three commands:
```bash
git log --oneline -8
grep -rn '^Status:' docs/project/readable-codebase/RD-*.md | grep -v done # next work
npm run ci # is HEAD green?
```
Then read `PLAN.md` for the design record, and the first `todo` ticket for the work.
## The agent loop
One supervisor session drives it; one `developer` agent executes each ticket:
1. Read the Order table. Pick the first `todo` whose dependencies are all `done`.
2. Spawn **one** `developer` agent: _"Read `CLAUDE.md`, then
`docs/project/readable-codebase/README.md`, then `RD-NN.md` and its Read-first list.
Execute it. End GREEN. Update the ticket Status and the README row in the same commit as
the code. Do not start another ticket."_
3. Verify with `task-runner`: `npm run ci`, `git log -1 --stat`, and that `Status:` now reads
`done`. Never mark a ticket done on an agent's report alone — the check is the exit code.
4. Green: next iteration. Red: stop and surface it.
**Run tickets sequentially.** Three properties make concurrent writes to one branch hostile:
`behaviour-spec.mdx` and `snippets.generated.ts` are regenerated and drift-checked, so two
agents regenerating conflict by construction; every ticket writes this README's Order table;
and the file sets overlap (the three wizards appear in RD-06, RD-07, RD-22 and RD-23).
Parallel work pays only for genuinely disjoint tickets, in separate git worktrees, merged
deliberately — RD-18/RD-19 (the ticket sweep) and the Phase 5 doc tickets qualify. Cap at
two. Note that RD-15 exists because 22 abandoned agent worktrees are still on disk.

The ID order already respects every dependency, so it is the recommended running order.
**Independent tickets.** RD-15 through RD-19 depend only on RD-01. Pull them forward to fill
a short session. Take RD-15 early: it makes every later repository search faster.
**Two ordering traps the table encodes.** RD-01 must precede RD-30, because RD-01 copies its
ticket template out of the directory that RD-30 archives. And four tickets edit the same two
documents in different sections — RD-09 rewrites the submit-idiom teaching, while RD-31 and
RD-32 fix section 6a and the stale paths. Sequential is fine. Never put those pairs in
parallel worktrees.
## Ticket template
```markdown
# RD-NN — Title
Status: todo | in-progress | done
Source: PLAN.md section <n>
## Why
## Read first
## Decisions (pre-made, don't relitigate)
## Files
## Steps
## Acceptance criteria
## Verification
## Out of scope
## Risks
```
Three rules when you write a ticket file, because the agent reads its ticket and not
`PLAN.md`:
1. **Copy the decision, never a pointer to it.** The verdict goes in the Decisions block,
verbatim.
2. **Inline the traps that apply to that ticket.** A trap recorded only in `PLAN.md`'s global
Risks section is a trap that fires.
3. **State acceptance as a command, not a sentence.** "Lands about 230 lines" is a design
estimate and nothing can check it. `npm run lint` has an exit code.
4. **Run every acceptance command against the tree before you hand the ticket over.** A
command that cannot pass is worse than no command: the agent either wastes a cycle or,
worse, "fixes" correct code to satisfy it. Four real misses so far, all in tickets written
by the supervisor:
- RD-06 grepped only `runIfSubmitting`, missing that one wizard spells it `runIfIndienen`.
- RD-08 grepped bare `onPrimary\|onRetry`, which can never return nothing — an unrelated
`uploadCtl.onRetry` exists in `upload-controller.ts`.
- RD-08 said "no machine changes" while also requiring a repo-wide grep to come back
clean, which forced comment edits in three machines. The two instructions contradicted
each other.
- RD-09 grepped `docs/ apps/ libs/ .claude/`, which also matched this backlog's own ticket
files (they name the deleted method as the history of `done` work) and 22 gitignored
abandoned worktrees. Satisfying it literally would have corrupted completed-ticket
history.
- RD-11 asserted `git grep "machineRemoteData\|LoadLifecycle"` returns nothing, but the
replacement it mandates is named **`fromLoadLifecycle`** — which contains the old name as
a substring. The check can never pass. **When the new name contains the old one, anchor
on word boundaries**: `git grep -w machineRemoteData` and
`git grep -nE "(^|[^a-zA-Z])LoadLifecycle\b"`.
Four habits that prevent all five:
- **Use `git grep`, not `grep -r`.** It searches tracked files only, so untracked and
gitignored paths never pollute the result. Measured on this repo: `grep -r` finds 132
hits under `.claude/`, `git grep` finds 0. This matters most for RD-17, RD-18 and RD-19,
which are repo-wide sweeps.
- **Anchor on a declaration** (`^ onRetry\(\)`), not on a name that may legitimately
appear elsewhere.
- **Scope every acceptance command to the ticket's Files list, never to a parent
directory.** This is the habit most often broken, including by the supervisor in RD-12:
the check `git grep "ActionState" -- apps/ssp/src/app/brief` cannot pass, because
`org-template.store.ts` lives in that directory and is deliberately out of scope until
RD-13. Name the files. If a command reaches a file the ticket says not to touch, one of
the two is wrong.
- **Prefer a number over a prohibition for anything that must not change.** "Do not rename
`BriefStatus`" invites reasoning around it; "this count must still be 54, and if it moves,
revert rather than adjust the number" does not. RD-11 renamed tags across 19 files with a
wire contract in the same file — on the same line in one place — and the count held.
## Troubleshooting
**`dotnet test` fails with `SQLite Error 1: 'no such table: <X>'`.** Stale, gitignored
`bigregister.db` artifacts from an old build. Found during RD-11, where a 0-byte file dated
months earlier failed 6 backend tests on an otherwise clean tree. Delete all three and re-run:
```bash
rm -f backend/bigregister.db backend/src/BigRegister.Api/bigregister.db \
backend/tests/BigRegister.Tests/bin/Debug/net10.0/bigregister.db
```
These are build artifacts, not fixtures — removing them is always safe.
