§39.4: tighten generic-type matching, reverting the harbor rename

Supersedes the previous commit's approach. Renaming harbor's four colliding
codes fixed one programme; tightening the matching rule fixes the rule, so a
room may be called anything. cr1/of/st1/st2 are restored and the examples are
byte-identical to their pre-§39 state -- which also means existing .dom
artefacts (evolved-3M*) stay valid, so migrate_ju3_rename.py is deleted.

The rule: Urb has exactly three GENERIC structural types (get_space_types:
qw/C O S/), the leaves the search creates. Measured across the corpus: 154 C,
110 O, 1 S, not one lowercase generic -- while every programme code is
lowercase, including single-character ones (r, t, m, n). Case is the
discriminator, not length. Every generic test was type[0].lower() in (...), a
case-insensitive PREFIX that swept up any programme code starting with those
letters; they now match the generic set exactly. 30 sites across dom, fitness,
graph, operators, programme, shapecurve and bubble.

NOT applied to the SEMANTIC prefixes: l/k/b/t classify programme codes by first
letter (graph.py builds bedroom<->toilet and kitchen<->living relations from
them) and stay prefix-based. Where the namespaces were mixed in one expression
they were split -- has_circulation's ("b","l","k","c") is three semantic
prefixes plus dom.is_circulation; access()'s ("l","c","s") is semantic l plus
the generic circulation set.

New: dom.GENERIC_{CIRCULATION,OUTSIDE,TYPES} + is_generic(); fitness.
_generic_class(), replacing the _t0 dispatch in quality_size/quality_width/
quality_proportion/value_rate -- the four terms that mattered most and that a
first sweep missed, since they dispatch through a t0 variable rather than an
inline test. graph._adjacency_target resolves a generic adjacency requirement
(programmes write "adjacency: [c, o]") to the generic set while every other
requirement keeps Perl's prefix semantics.

Two subtleties: S is in both generic sets but takes the OUTSIDE parameter
families -- a first translation tested circulation first and silently gave S
the circulation params, caught by test_get_space_params_sahn_proportion. And
validate_codes survives, narrowed to a code spelled exactly C/O/S, which is a
genuine ambiguity; merely starting with c/o/s is now fine.

Invariant asserted as a test: test_scoring_is_invariant_under_programme_code_
spelling relabels one tree and its config together and re-scores. Bit-identical
across 12 comparisons (6 seeds x collapse on/off).

Re-baseline (seed 1, 20k, original names): 58 fails (15 hard / 43 soft) against
the real 37-instance programme, with cr1 at 79.1 m2 vs declared 80 (was 32.9
and 17.1), of/st1/st2 all present and in band, and one fail naming any of them.
57 -> 58 on a 5-instance-harder programme is within noise: "did not regress".

Fallout (§39.5): 2g7.5's CP-SAT seeder win does not survive. Over 6 seeds --
harbor real 102/114 (cpsat loses), harbor old-effective 98/99 (tie, so the win
was already marginal), maple-court 156/144 (cpsat wins). maple is the control:
the solver did not regress, harbor's programme changed. Test xfail'd with that
reason plus a maple companion; both assign_solver flags stay default off.
Filed homemaker-py-w6x to re-check other narrow-margin harbor A/Bs.

345 passed, 1 xfailed, same 7 pre-existing fixture failures.

@ -5156,62 +5156,114 @@ document was measured against a **32-instance effective programme, not the
harbor-house (§13.9, §13.11, §17, §20, §23, §37.1, §37.7) are internally
consistent but are not measuring the programme as written.
### 39.3 What shipped — loud validation + harbor rename, re-baselined
### 39.3 What shipped — tighten the matching rule at the source
**The `class:` key was NOT built, deliberately.** Auditing every use of the
prefix rule first showed it runs far deeper than `c`/`o`/`s`: `l`/`k`/`b`/`t`
carry real adjacency semantics too (`graph.py` builds bedroom↔toilet and
kitchen↔living relations from first characters, `fitness.py` gates access and
public-entrance checks on them). Re-plumbing that into a declared type system
would invalidate the entire corpus and every baseline in this document, for a
problem whose actual damage is the **silence**, not the prefix convention.
A first pass took the cheaper route from the bead's design: refuse a colliding
programme code at load, and rename harbor's four. **That has been superseded and
the rename reverted** — `cr1`, `of`, `st1`, `st2` are back. The right fix was to
tighten the matching rule so a room may be called anything at all.
Two facts made the smaller fix clearly sufficient:
**The rule.** Urb has exactly three GENERIC structural types
(`get_space_types`: `qw/C O S/`) — the leaves the *search* creates. Measured
across the whole corpus: **154 `C`, 110 `O`, 1 `S`, and not one lowercase
generic**, while every programme code is lowercase — including single-character
ones (`r`, `t`, `m`, `n`). So **case is the discriminator, not length**, and the
two namespaces are cleanly separable. Every generic test used to be
`type[0].lower() in (...)` — a case-insensitive *prefix* — which swept up any
programme code starting with those letters. They now match the generic set
exactly.
1. **No corpus programme has ever declared a bare `c`/`o`/`s` code** (checked
across all ten `examples/*/patterns.config`). So `check_space_counts`'
skip never protected a legitimate case — generic types are not in `spaces`
at all — and could only ever discard a declared room.
2. **Nothing references the four harbor codes** in any `adjacency:` or
`co_locate:` list, so renaming them is local.
Crucially this is **not** applied to the SEMANTIC prefixes. `l`/`k`/`b`/`t`
classify *programme codes* by first letter (`k1` is a kitchen; `graph.py` builds
bedroom↔toilet and kitchen↔living relations from them) and stay prefix-based.
Only the generic-type tests were tightened — 30 sites across `dom.py`,
`fitness.py`, `graph.py`, `operators.py`, `programme.py`, `shapecurve.py` and
`bubble.py`. Where the two namespaces were mixed in one expression they were
split: `has_circulation`'s `("b","l","k","c")` is now three semantic prefixes
*plus* `dom.is_circulation`, and `access()`'s `("l","c","s")` is the semantic
`l` *plus* the generic circulation set.
Shipped instead:
New in `dom.py`: `GENERIC_CIRCULATION`/`GENERIC_OUTSIDE`/`GENERIC_TYPES` and
`is_generic()`. New in `fitness.py`: `_generic_class()`, which replaces the
`_t0()` first-character dispatch in `quality_size`/`quality_width`/
`quality_proportion`/`value_rate` — the four terms that mattered most, and the
ones a first sweep missed because they dispatch through a `t0` variable rather
than an inline test.
- **`programme.validate_codes`** (new, `RESERVED_PREFIXES = ("c", "o", "s")`)
raises with the full explanation and a pointer here. Called from **both**
parse paths — `programme._parse_spaces` *and*
`fitness.Fitness._load_programme`, which parse `conf["spaces"]`
independently, so validating only one would leave the other door open.
`l`/`k`/`b`/`t` are explicitly **not** reserved: they flavour heuristics but
never discard a requirement.
- **harbor-house / harbor-house-l0 renamed**: `cr1``fr1`, `of``ao`,
`st1``gs1`, `st2``gs2`. Each new prefix is unused in harbor *and*
semantically neutral (`f`/`a`/`g` carry no adjacency meaning, unlike
`l`/`k`/`b`/`t`), and the two storage codes still share one prefix, so the
prefix-sharing structure `fitness.evaluate_building`'s per-code plot-ratio
term depends on is preserved. `name:` fields are unchanged.
- **`experiments/migrate_ju3_rename.py`** rewrites `type:` lines in `.dom`
files produced before the rename (`--check` to dry-run). Any pre-rename
artefact — notably the `evolved-3M*.dom` harbor runs — **must** be migrated
or its affected leaves will read as unmatched generics.
Two subtleties worth recording:
**Re-baseline** (`homemaker-evolve init.dom --budget 20000 --workers 4
--seed 1`, same seed/budget/settings as §38's run, so the two are directly
comparable):
- **`S` is in both generic sets but takes the OUTSIDE parameter families.** The
original dispatch was `c0 == "c"` then `c0 in ("o", "s")`, so sahn fell to
outside. A first translation tested circulation first and silently gave `S`
the circulation params; `test_get_space_params_sahn_proportion` caught it.
- **Generic adjacency references are lowercase in `patterns.config`** — every
corpus programme writes `adjacency: [c, o]`. `graph._adjacency_target` resolves
those to the generic set while leaving every other requirement on Perl's
prefix semantics (a requirement `t` still matches `t1`, `t2`, …). Previously a
room next to `cr1` "Common Room" counted as being next to circulation.
| | effective programme | total fails | `fr1` area (declared 80) | `ao`/`gs1`/`gs2` |
`programme.validate_codes` survives but is narrowed to what is still a genuine
ambiguity: a code spelled **exactly** `C`, `O` or `S`. Codes merely starting
with those letters are now fine — that was the bug, not the rule.
**The invariant, asserted as a test.**
`test_scoring_is_invariant_under_programme_code_spelling` builds one harbor
layout, then relabels that exact tree *and* its config together and re-scores:
same geometry, same topology, only the spelling differs. Bit-identical across
12 comparisons (6 seeds × in-search collapse on/off). Renaming a room can no
longer change what a layout scores.
### 39.4 Re-baseline
`homemaker-evolve init.dom --budget 20000 --workers 4 --seed 1` — same seed,
budget and settings as §38's run, so the two are directly comparable. Harbor
keeps its **original** code names throughout; only the matching rule changed.
| | effective programme | fails | `cr1` (declared 80) | `of` ×2 / `st1` / `st2` |
|---|---|---|---|---|
| before | 32 instances | 57 | **32.9 and 17.1** (two leaves, `count: 1`, no too-many fail) | **absent, zero fails** |
| after | **37 instances** | **55** (13 hard / 42 soft) | **87.2** | **all present: 14.2, 11.5, 24.6, 18.7** |
| before §39 | 32 instances | 57 | **32.9 and 17.1** (two leaves against `count: 1`, and no too-many fail) | **absent, zero fails** |
| after §39.3 | **37 instances** | 58 (15 hard / 43 soft) | **79.1** | **12.2, 11.0 / 22.5 / 20.1** |
Every one of the five previously-lost room instances is now placed and sized
inside its declared sigma band (`fr1` 80±10, `ao` 12.5±2.5, `gs1` 22±4,
`gs2` 18±3.5), and **no failure in the result mentions any of the four codes**.
The fail count did not rise despite the programme being 5 instances harder —
though at one seed each, 57 vs 55 is within noise and the honest claim is
"did not regress", not "improved". The robust result is the room placement.
Every one of the five previously-lost room instances is placed and sized inside
its declared sigma band, and exactly one failure in the whole result mentions
any of the four codes (an adjacency miss on one office). The common room is
within 1 m² of its brief, having previously converged to a fifth of it.
Fail count 57 → 58 on a programme that is 5 instances harder: at one seed each
that is within noise, and the honest claim is **"did not regress"**, not
"improved". The robust result is the room placement. (An intermediate
measurement taken with the codes renamed rather than the rule tightened gave 55
on the same seed — the same picture.)
**Historical numbers.** Every harbor-house fail count recorded before §39 was
measured against the 32-instance effective programme. They remain valid relative
to each other but are not comparable to post-§39.3 numbers; treat 58 as the new
harbor reference point at this budget.
### 39.5 Fallout: `2g7.5`'s CP-SAT seeder win does not survive the correction
`§37.7` recorded a real, low-noise seeder-level win for `assign_solver="cpsat"`
on harbor-house, guarded by
`test_assign_cpsat_matches_or_beats_greedy_secondary_adjacency`. That test now
fails, and the cause is the corrected programme, not the solver. Measured over
6 seeds:
| programme | greedy | cpsat | |
|---|---|---|---|
| harbor, real 37-instance | 102 | 114 | cpsat loses |
| harbor, old 32-instance effective | 98 | 99 | tie — the "win" was already marginal |
| maple-court (namespace-clean, untouched by §39) | 156 | **144** | **cpsat wins** |
maple-court is the control: CP-SAT's advantage is intact on a programme whose
codes never collided, so nothing about the assignment solver regressed. On
harbor the four restored codes — with real adjacency requirements that were
previously dropped — change the assignment problem enough to flip an aggregate
that was a tie to begin with. The harbor test is marked `xfail` with this
reason and a companion test asserts the maple-court result; both
`assign_solver` flags remain default off, as `§37.7` already concluded for
independent reasons.
The general lesson: **any harbor-house A/B decided by a small margin before §39
was decided against a programme missing 14% of its rooms** and is worth
re-checking if anything depends on it.
**Historical numbers.** Every harbor-house fail count recorded before this
section was measured against the 32-instance effective programme. They remain
valid relative to each other but are not comparable to post-`ju3` numbers;
treat §39.3's 55 as the new harbor reference point.

"""Rename harbor-house's colliding room codes in existing `.dom` files.
`homemaker-py-ju3` (DESIGN.md §39.2) renamed four harbor-house programme codes
that collided with Urb's reserved generic type prefixes (``c`` = circulation,
``o``/``s`` = outside). Any `.dom` produced **before** that change still carries
the old leaf types, and will score differently against the renamed programme
the old types are no longer declared, so every affected leaf reads as an
unmatched generic instead of the room it was.
This matters for artefacts not checked in at the time, notably the
``evolved-3M*.dom`` harbor-house runs.
Mapping (chosen so each new prefix is unused in harbor-house *and* carries no
adjacency semantics of its own ``l``/``k``/``b``/``t`` do, ``f``/``a``/``g``
do not while preserving the original prefix-sharing structure, i.e. the two
storage codes still share one prefix):
cr1 -> fr1 Common Room with Fireplace
of -> ao Staff Office

# Structural predicates (mirrors Urb::Dom::Is_Outside etc.)
# --------------------------------------------------------------------------- #
# homemaker-py-ju3 / DESIGN.md §39.4 — generic structural types vs programme codes.
#
# Urb has exactly three GENERIC structural types (``get_space_types``:
# ``qw/C O S/``) — C circulation, O outside, S sahn (an outside court that also
# serves as circulation, hence a member of both sets). These are the leaves the
# SEARCH creates; they are canonically UPPERCASE and the whole corpus obeys that
# (measured: 154 ``C``, 110 ``O``, 1 ``S``, and not one lowercase generic).
#
# Programme room codes are a different namespace and are canonically lowercase
# (``k1``, ``b1``, ``cr1``, ``of``, and single-character ones like ``r``, ``t``,
# ``m``, ``n``). CASE is therefore the discriminator, not length.
#
# The predicates below used to test ``type[0].lower() in (...)`` — a
# case-insensitive PREFIX match — which silently swept up any programme code
# beginning with c/o/s: ``cr1`` "Common Room with Fireplace" was classified as
# circulation, ``of`` "Staff Office" as outside space. Matching the generic set
# EXACTLY keeps Urb's semantics for the leaves it was written for while leaving
# programme codes alone, so a room may be called anything at all.
#
# NB this is deliberately NOT the same rule as the SEMANTIC prefixes (l/k/b/t):
# those classify PROGRAMME CODES by first letter (``k1`` is a kitchen) and must
# stay prefix-based. Only the generic-type tests are tightened.

# leaf type starting with "c" is circulation, "o"/"s" is outside — and
# programme room codes share that namespace. A code starting with one of these
# letters is silently reinterpreted as a generic type, with three unannounced
# consequences: ``graph.check_space_counts`` skips it entirely (so the room is
# never required), ``Fitness.get_space_params`` returns the generic
# ``*_circulation``/``*_outside`` parameters instead of the declared ones, and
# ``dom.is_circulation``/``is_outside`` flip (changing value rate, crinkliness
# treatment, and whether the leaf supplies daylight to neighbours).
# homemaker-py-ju3 (DESIGN.md §39.4): Urb has exactly three GENERIC structural
# types — ``C`` circulation, ``O`` outside, ``S`` sahn — which are the leaves the
# SEARCH creates, canonically uppercase. Programme room codes are a separate,
# lowercase namespace.
#
# harbor-house shipped four such codes for years — ``cr1`` "Common Room with
# Fireplace" had its declared 80 m² read as circulation's 0-30 m², and 14% of
# the programme was silently optional. Refusing the code at load turns a silent
# misread into a loud one. The other prefixes with semantics (l/k/b/t) are NOT
# reserved: they only flavour adjacency heuristics and never discard a
# requirement, so programme codes may use them freely.

# Fireplace" was read as circulation, and 14% of the programme became optional).
# That is fixed at the source — see the GENERIC_* note in ``dom.py`` — so a room
