docs: write docs/loopwright/principles.md (#11)

[SamuelDenani]

What and why

Adds docs/loopwright/principles.md — the descriptive statement of loopwright's
core opinions and its detail territory, with the classification rule and the
amendment mechanism.

Loopwright's identity is currently written through its stack. The reason it
exists is not the stack, and three open RFCs already cite this boundary
textually: #7 ("a detail behind a contract, per the principles RFC", and
peer-to-peer "conflicts with the mediated principle"), #8 ("the section
boundaries mirror the principles RFC"), and #6, which carries the defaults rule
nearly verbatim. They do not need the document to enforce anything — they need
it to exist and to name things, so they can cite it.

The document is descriptive: no skill consults it, no gate checks it, no RFC
is required to carry a classification line.

Part of #11. Spec: docs/specs/issue-11.md.

Plan recap

Step	What landed	Commits
1	File, section spine, Context (autonomy as destination)	cbf6eb8, 2280f70
2	P1–P12, each with rejects: and an enforcement pointer	8348fc5
3	Rationale prose below the list	07547ec
4	Detail territory T1–T8, T5's four capabilities	835971a, d601107, f38fa53
5	Classification rule and Amendments	5870e63
6	Cross-RFC consistency, style, 8 deferred fixes	b7b01be, 7a4274d, 2ece483
7	Gate run and readthrough of all 8 criteria	—
—	Pre-PR fixes from the final review	8c45702

Gate: green, exit 0 — "passed, 2 warning(s), 6 improvement(s)". Coverage
improved on all four metrics; duplication and average complexity fell. Both
warnings are pre-existing and not from this diff (see Known gaps).

No test, by design: markdown is outside every collector's scope
(.loopwright/config.json scopes sources.roots to .mjs under
.loopwright/scripts and .loopwright/tests), so each step substituted a
check first command that fails before the change and passes after.

Rulings I made

Each with what it costs if it is wrong.

On content

1. T7's "works on a non-JS host" claim stays out of the doc. RFC RFC: Core principles, opinionated about process, agnostic about stack #5's body
   asserts changesets serves a Go host because the engine is already Node. That
   is false — @changesets/cli assumes a package.json. The seam and the
   default travel; the justification does not. Cost if wrong: the doc is silent
   on an RFC claim until RFC: Versioned releases with changesets, and automatic changesets in the loop #9 is grilled.
2. P5 asserts that disabling a configured check blocks. collectorRegressions
   returns STATUS.BLOCK; RFC: One config file, YAML, sectioned by feature #8's open question 3 understates the engine. Cost if
   wrong: RFC: One config file, YAML, sectioned by feature #8 corrects its own description when grilled.
3. P2 keeps two enforcement pointers. AC 2 forbids line numbers, not a second
   path, and P2's two clauses have two enforcers — the gate for configured
   checks, babysit-pr for review findings. Cost if wrong: anyone ticking AC 2
   literally stops here; one sentence of explanation.
4. No T9. First-time setup has no seam of its own and the list is eight.
   Cost if wrong: a territory is missing, and the Amendments section the doc
   defines is the fix.
5. P8 is not weakened to dodge the tension with RFC: Versioned releases with changesets, and automatic changesets in the loop #9's release workflow, which
   creates a tag with no opt-in. Changesets' usual shape is a release PR a human
   merges, which satisfies P8 through the merge. Cost if wrong: RFC: Versioned releases with changesets, and automatic changesets in the loop #9 needs an
   explicit opt-in for the tag.
6. "A Go host needing Node in CI is not coupling" stays. It is this RFC's own
   decision, not a claim about what RFC: Stack connectors, decouple the quality gate from JS/TS #6 settled; RFC: Stack connectors, decouple the quality gate from JS/TS #6's open question 4 stays open.
   Cost if wrong: a reader thinks RFC: Stack connectors, decouple the quality gate from JS/TS #6 agreed.
7. The doc records the default that exists and is amended when a proposal
   lands. The one-way rule forbids contradicting an RFC, not anticipating an
   unlanded one — RFC: Isolated agent runtime with a mediated, async channel #7 proposing Docker does not make Docker a present default.
   Cost if wrong: the doc trails RFC: Isolated agent runtime with a mediated, async channel #7 by one amendment.
8. The "Default today" column was renamed to "Default", with two sentences
   defining what a default is. Three cells named decided-but-unbuilt defaults
   (mise has no toolchain layer at all, changesets has no .changeset/,
   container does not exist), so the heading promised present-tense fact the
   values could not deliver. Cost if wrong: a reader loses the
   implementation-state signal — which would have gone stale on every landing.

Where I was wrong and corrected myself

Four of my own fix instructions were defective, each the same way: I took a
correct review finding and prescribed a more specific fix than I had grounds
for, without reading the code.

9. My seam qualification of the swap rule was backwards and became the
   review's only blocker. I assumed "no seam" meant "no swap route". T4 has no
   seam because its swap needs none — it is the only territory whose swap
   route exists today (config.json limits.complexity plus
   quality-gate.md ## Tuning). It also broke RFC: One config file, YAML, sectioned by feature #8's cited claim, whose config
   sketch puts limits under gate: — that section is T4. Reverted to the
   original phrase with T6 as the sole exception.
10. My "name the engine as incomplete" fix overshot, producing a paragraph
    that contradicted its own lead-in and RFC RFC: Core principles, opinionated about process, agnostic about stack #5's verbatim "an empty pointer is
    itself a finding". The last sentence achieves the whole purpose alone.
11. My "author" discriminator for the baseline was false.
    detect-stack.mjs main() does writeFileSync(CONFIG_PATH, ...), RFC: One config file, YAML, sectioned by feature #8 says
    "the installer and the future TUI write it", RFC (draft): Interactive installer for first-time setup #10 says "The TUI only writes
    config.yml". Both files are engine-written. Reverted to P3's own axis:
    hand-editable vs never hand-edited.
12. My request to soften P10's sentence should not have been made. The
    softening became a known-divergence note, which Out of scope bars. Restored
    to the RFC's declarative form.
13. A finding of mine was rejected by review and I accept it. I claimed P4's
    rejects: line was weakened by replacing "unconfigured" with "out". Review
    traced the mechanism: integrity metrics have no collector adapter — they come
    from collectStaticAnalysis, always called — so no integrity.* metric can
    ever report unconfigured. The spec's seed word was factually wrong.

On process

14. Five minors were carried into step 6 as mandatory listed work rather than
    one extra fix round, since that step edits the file anyway. Cost if wrong:
    five minors arrive as "look for something".
15. A fix was dispatched before the step-4 review because my own verification
    found two factual errors in the table, which is the loop's other trigger.
    Cost if wrong: none — the step review saw the whole step diff.
16. Three reviews were skipped: step 5 (14 lines of declarative prose, AC 4
    verified point by point) and the second fix rounds of steps 4 and 6 (a column
    rename and five textual corrections, each verified individually). All of that
    text was reread by the final branch review. Cost if wrong: a defect reaches
    the PR that a dedicated reviewer would have caught.

Known gaps, consciously shipped

1. T5's "exactly four capabilities" closure claim is false. The loop also
   requires host-scheduled re-invocation (/loop, declared in
   babysit-pr/SKILL.md:3, absent from this repo) and a native task list
   (TaskCreate, mandated in execute-issue and grill-rfc). The failure mode
   is silent: a host implementing only the four reaches the draft PR, then cannot
   start the babysit, the PR never leaves draft, claude-code-review.yml never
   fires because of if: !draft, and the loop stalls with no error. Not fixed
   here: adding a capability is a core change by the doc's own rule, and AC 3
   requires exactly four. The vehicle is an amendment to RFC: Core principles, opinionated about process, agnostic about stack #5 through the
   Amendments section this PR adds. The session that produced this PR is live
   evidence — TaskCreate was unavailable in it.
2. .claude/agents/reviewer.md:4 grants Bash, which is write-capable, so
   P10's own enforcer can commit over the diff it reviews. The three sibling
   reviewers carry Read, Grep, Glob only. Out of scope for a docs-only task;
   worth its own issue. The spec's justification row was corrected in 8c45702
   so the record does not claim otherwise.
3. audit.high regressed 0 → 2 — brace-expansion and js-yaml, both
   with a fix available upstream. Advisory-database movement, not this diff,
   which touches no package file. High warns by design. Worth a chore PR; do not
   add an audit.ignore entry, since fixes exist.
4. P12's pointer names collect-metrics.mjs, but nothing there rejects an
   invented key. quality-gate.mjs writes metrics: current wholesale into
   the baseline and evaluation iterates the config, so a connector-invented key
   would be persisted and never scored. The honest pointer today is empty. Left
   as is because no third-party connector exists yet.
5. P10's rejects: line is the literal negation of its assertion and refuses
   no change anybody would propose. Nine of the twelve do real work; this is the
   one a reader can skip with no loss.
6. The classification rule has no branch for a T7- or T8-shaped proposal.
   "Replace changesets with knope" alters neither what counts as done, nor how
   work flows, nor how a fact is measured, nor where a step runs — the rule
   returns no verdict and the reader falls back to the territory table.
7. The spec is stale in two places against the doc that shipped: it specifies
   a "Default today" column (ruling 8 renamed it) and an enforced by: count of
   12 (it is 13, the 13th being prose). Noted so nobody reads a pass as a fail.
8. RFC RFC: Core principles, opinionated about process, agnostic about stack #5's body still carries the false T7/non-JS claim (ruling 1) and still
   asserts the swap rule without T6's exception (ruling 9). Both need a close-out
   pass on RFC: Core principles, opinionated about process, agnostic about stack #5 itself.

For #12

P1 admits no exception, but docs/loopwright/loop-harness.md:70-74 documents
one — "except the grill phase itself, whose task spine and drafts are
session-scoped, so a crashed grill restarts". #12 replaces that rule with a
reference to P1, so it must decide where the exception lives: mechanics that
stay, or a P1 violation.
