ADR 0080: the development cycle is checked, not trusted

The flow the process overview draws — idea/symptom -> decision -> to-be design -> code ->
as-is — was enforced by nothing. cycle.py now refuses a to-be design naming no decision, an
in-progress/implemented design naming no owning code, a located/fixed issue with no owner,
a fixed/resolved issue with no fix, and a graduated research overview that does not say what
it became. AGENTS.md carries the cycle and a where-to-look table so a fresh session (or a
cleared context) finds the chain in frontmatter instead of assuming it. Grounding the check
surfaced two real gaps, fixed here: the work-ahead design named no owning code, and research
003 listed one became target twice.

"""The development cycle, checked.
The knowledge flow (00-META/process/00-overview.md) says work moves idea -> research ->
decision -> to-be design -> code, and symptom -> issue -> diagnosis -> fix. Those are rules,
and a rule states how it is checked (AGENTS.md) -- this is how. Everything here reads only
frontmatter, because status lives in frontmatter and nowhere else.
What is enforced:
design every 03-DESIGN doc parses, carries `layer:` matching its directory, and a
known `status:`. A TO-BE doc names at least one decision (`decisions:`) -- no
design without a decision -- and once `in-progress` or `implemented` it names
its owning code (`code:`) -- no development without a design that says where.
issues a known `status:`; once `located` or `fixed`, `located-in:` names the owner;
once `fixed` or `resolved`, `fixed-by:` says what fixed it (prose counts --
"nothing, the capability existed" is an answer).
research a known `status:`; a `graduated` overview says what it `became:`, and every
target it names exists.
Deliberately NOT enforced: `resolved` issues may leave `located-in` empty (a symptom that
turned out not to be a defect has no owner), and as-is docs need no decisions (they
describe what exists, not what was decided).

The flow above is a rule, and a rule states how it is checked:
[`00-META/checks/cycle.py`](../checks/cycle.py) refuses a to-be design that names no
decision, an `in-progress`/`implemented` design that names no owning code, an issue marked
`located`/`fixed` with no owner or `fixed`/`resolved` with no fix, and a `graduated`
research overview that does not say what it became. Run it with `records.py` and `index.py`
before any HQ merge. What the checks cannot see — that code work actually started from a
handoff — is held by playbooks [04](04-build-handoff.md) and [07](07-feature-branches.md):
a feature branch exists because a design or an issue sent it.

# 80. The development cycle is checked, not trusted
## Context
[ADR 0019](0019-how-this-repository-works.md) made this repository the source of truth, and the
process overview drew the flow work must follow: an idea or a symptom, a decision, a to-be design,
a build in a code repository, an as-is update on shipping. The playbooks describe every step, and
frontmatter carries every status.
But the flow itself was enforced by nothing. A design could appear citing no decision; a design
could sit `in-progress` naming no code; an issue could be `fixed` by nobody knows what. Each is
indistinguishable from correct work until somebody reads carefully — and the whole point of the
playbooks is that nobody should have to hold this repository in their head. A session that starts
cold (or an agent after a context clear) must be able to *find* the chain by following frontmatter
pointers, which only works if the pointers are reliably there.
## Decision
The development cycle is enforced mechanically, to the extent frontmatter can carry it:
- **No design without a decision** — every to-be design names at least one record in `decisions:`.
- **No development without a design that says where** — an `in-progress` or `implemented` design
names its owning code in `code:`.
- **No owner-less diagnosis, no fix-less fix** — an issue marked `located` or `fixed` names
`located-in:`; one marked `fixed` or `resolved` says `fixed-by:` (prose counts — "nothing, the
capability existed" is an answer).
- **No silent graduation** — a `graduated` research overview says what it `became:`, and the
targets exist.
[`00-META/checks/cycle.py`](../00-META/checks/cycle.py) refuses violations, beside `records.py`
and `index.py`; all three run before any merge here. What frontmatter cannot see — that code work
actually started from a handoff — remains held by playbooks 04 and 07: a feature branch exists
because a design or an issue sent it, and a merge is a human checkpoint.
## Consequences
A `/clear` costs little: [`AGENTS.md`](../AGENTS.md) now carries the cycle and a where-to-look
table, and the chain a fresh session needs is guaranteed present in frontmatter rather than
reconstructed from memory. The checks are the floor, not the ceiling — they verify pointers exist,
not that their content is true; reading remains the job.

## The development cycle
Work enters as an **idea** (playbook [01 — research](00-META/process/01-research.md)) or a
**symptom** (playbook [03 — issues](00-META/process/03-issues.md)), becomes a **decision**

[04](00-META/process/04-build-handoff.md), on a feature branch per playbook
[07](00-META/process/07-feature-branches.md)) — and on shipping the as-is is updated and the
design flips to `implemented`. **No design without a decision; no development without a design

| What does this word mean? | [`00-META/glossary.md`](00-META/glossary.md) |
| How do I do X in this repo? | [`00-META/process/`](00-META/process/) — the playbook index is in `00-overview.md` |

| What is being built / already runs? | [`03-DESIGN/01-to-be/`](03-DESIGN/01-to-be/) / [`03-DESIGN/00-as-is/`](03-DESIGN/00-as-is/) — each doc's frontmatter says its status, decisions and owning code |
