+### Features
+
+* a model is checked from the shell, advice included, with no consumer installed ([#192](https://github.com/energy-models/math-spec/issues/192)) ([941126c](https://github.com/energy-models/math-spec/commit/941126cd95af7decb0d37538e93c4f7c4ad54935))
+* a named expression may give a value per region, and no two regions may claim one coordinate ([#168](https://github.com/energy-models/math-spec/issues/168)) ([e12e7da](https://github.com/energy-models/math-spec/commit/e12e7da502e959191066ab220097edbb2ae566ee))
+* a piecewise method answers which curvature it is exact for ([#135](https://github.com/energy-models/math-spec/issues/135)) ([6f0fff1](https://github.com/energy-models/math-spec/commit/6f0fff1bc29fe0a958999579b08a5d0ca4a42848))
+* a program is the second public state, and one call reaches it ([#177](https://github.com/energy-models/math-spec/issues/177)) ([c9ee1ab](https://github.com/energy-models/math-spec/commit/c9ee1ab2607fce5618a4b3df56082d9ec1b2b3a5))
+* a snapshot is a timestamp, in the file and in every rung's network ([#159](https://github.com/energy-models/math-spec/issues/159)) ([dd5122e](https://github.com/energy-models/math-spec/commit/dd5122ec2184bdaf3145e56949e42a6fa0612948))
+* advice carries which pass said it and which declaration it is about, so a consumer can filter rather than parse ([#195](https://github.com/energy-models/math-spec/issues/195)) ([89408f6](https://github.com/energy-models/math-spec/commit/89408f6fae500df661bda66cc2f0ef100b691636))
+* **examples:** a link delivers to as many buses as its data declares, not two ([#273](https://github.com/energy-models/math-spec/issues/273)) ([0ece0d8](https://github.com/energy-models/math-spec/commit/0ece0d86794a86664e2596428df25e319eb6b56e))
+* **language:** dimension members and lookup maps come from the data, rather than from the file ([#169](https://github.com/energy-models/math-spec/issues/169)) ([f3c4e5f](https://github.com/energy-models/math-spec/commit/f3c4e5fa492ece1ae0af1ac27e7b0a36266a287a))
+* **language:** which dims a mask reads is the language's answer, so two consumers cannot restrict one model differently ([#269](https://github.com/energy-models/math-spec/issues/269)) ([350b1ed](https://github.com/energy-models/math-spec/commit/350b1ed5b572146f8168297e6ded1a234c6fc619))
+* **parser:** a refused expression names the rewrite rather than only the grammar's complaint ([#332](https://github.com/energy-models/math-spec/issues/332)) ([02121b8](https://github.com/energy-models/math-spec/commit/02121b8761f6924d14e2287e8aed782baab8fe27))
+* pin the eight names that keep this package and its consumer in step ([#51](https://github.com/energy-models/math-spec/issues/51)) ([15a354b](https://github.com/energy-models/math-spec/commit/15a354b1173f105d85113db6abc2f4e5ac28a6e3))
+* position(dim) replaces index(dim, i), converting on the left ([#31](https://github.com/energy-models/math-spec/issues/31)) ([8f78ac5](https://github.com/energy-models/math-spec/commit/8f78ac54f5ff6a790cff4d4b730bb2abd27bef7c))
+* **program:** a parameter says which piecewise block derived it, and a label space keeps its dtype ([#227](https://github.com/energy-models/math-spec/issues/227)) ([515dbd5](https://github.com/energy-models/math-spec/commit/515dbd5054dae8ae61fd8818be4d204e1d98950b))
+* **program:** a piecewise assumption names the data it is about, and a derived parameter says how it is filled ([#237](https://github.com/energy-models/math-spec/issues/237)) ([48431b1](https://github.com/energy-models/math-spec/commit/48431b1a72197570ab291103267212d269141936))
+* **program:** a piecewise block is kept as facts — its breakpoints, its mask, and what it assumes of the data ([#228](https://github.com/energy-models/math-spec/issues/228)) ([2fdbd6f](https://github.com/energy-models/math-spec/commit/2fdbd6f5760975132f0dc9db605b11f4d2cc7103))
+* **program:** a program says which of the language's constructs it uses ([#207](https://github.com/energy-models/math-spec/issues/207)) ([4e55a15](https://github.com/energy-models/math-spec/commit/4e55a15df57bef28364049ff16d449312d06aebd))
+* **program:** a resolved where is a first-class Mask whose leaves carry their dims, and the where grammar is package-private ([#327](https://github.com/energy-models/math-spec/issues/327)) ([53cc352](https://github.com/energy-models/math-spec/commit/53cc3522e917a5849ce3150585c2c9e05a8ea162))
+* **program:** the conjuncts of a where mask are the program's to give, not each consumer's to re-derive ([#313](https://github.com/energy-models/math-spec/issues/313)) ([db63d3c](https://github.com/energy-models/math-spec/commit/db63d3ca90079e4031a9339ea7749c0567b31be9))
+* PyPSA in one file — every rung stated, shown beside its data, and solved to the same objective on both lanes ([#122](https://github.com/energy-models/math-spec/issues/122)) ([46544e3](https://github.com/energy-models/math-spec/commit/46544e3d405d8ed1f982053934c3d033e2ccbe19))
+* rung 11 — PyPSA's ac-dc-meshed example, whole ([#151](https://github.com/energy-models/math-spec/issues/151)) ([a133044](https://github.com/energy-models/math-spec/commit/a1330441ba7926aeedc086afa48f2efa8971fa10))
+* rung 12 — linearized unit commitment, a file of its own ([#152](https://github.com/energy-models/math-spec/issues/152)) ([69b926e](https://github.com/energy-models/math-spec/commit/69b926e64b2431ad723b92e614b4c43523525253))
+* rung 13 — transmission losses in tangent form, a file of its own ([#153](https://github.com/energy-models/math-spec/issues/153)) ([379ce23](https://github.com/energy-models/math-spec/commit/379ce2316b2146ca064bcc3bac0d3ea0bd995011))
+* rung 14 — two-stage stochastic with CVaR, a file of its own ([#154](https://github.com/energy-models/math-spec/issues/154)) ([41b427d](https://github.com/energy-models/math-spec/commit/41b427daa7525f7fd6368488e005e0a42983f3fd))
+* rung 15 — investment periods with a growth limit, a file of its own ([#155](https://github.com/energy-models/math-spec/issues/155)) ([285aac3](https://github.com/energy-models/math-spec/commit/285aac35bda2ee69a2872a6b20618f5827c3d19f))
+* the notes a check prints are reachable, so a consumer surfaces them rather than re-deriving them ([#184](https://github.com/energy-models/math-spec/issues/184)) ([19ef814](https://github.com/energy-models/math-spec/commit/19ef81411b619ae187f7763338202e1e06401cf0))
+* upright is what the model is given, italic is what the solver chooses ([#44](https://github.com/energy-models/math-spec/issues/44)) ([cbccc68](https://github.com/energy-models/math-spec/commit/cbccc68bef12cb4931f66a9447a71a9cb1174158))
+
+
+### Bug Fixes
+
+* a file the language accepts is one every consumer can build, the edge rules being decided at load ([#211](https://github.com/energy-models/math-spec/issues/211)) ([a362ff0](https://github.com/energy-models/math-spec/commit/a362ff0e9bb582ffa11edadec69daf700f7cea3f))
+* **advice:** a model handed over as a program is advised of everything a file is ([#217](https://github.com/energy-models/math-spec/issues/217)) ([4fc50e6](https://github.com/energy-models/math-spec/commit/4fc50e60b7387c657a7571650a151054f564308b)), closes [#210](https://github.com/energy-models/math-spec/issues/210)
+* **docs:** the homepage feature cards render as cards rather than as loose rules and paragraphs ([#145](https://github.com/energy-models/math-spec/issues/145)) ([b88e5dc](https://github.com/energy-models/math-spec/commit/b88e5dc8883f0bc6bc0f5809c688139055715f57))
+* enforce the two rules a named offset or width was always said to obey ([#61](https://github.com/energy-models/math-spec/issues/61)) ([5bd92dc](https://github.com/energy-models/math-spec/commit/5bd92dc47630d1fb8572d18e80060446c257727c)), closes [#58](https://github.com/energy-models/math-spec/issues/58)
+* **examples:** a committable modular unit that is not extendable gets the rows PyPSA builds for it ([#271](https://github.com/energy-models/math-spec/issues/271)) ([5af0ac8](https://github.com/energy-models/math-spec/commit/5af0ac8cb15271c4b6982e4397604fe3dfb5cb10))
+* **language:** a boolean literal in a where is decided at load wherever it stands ([#216](https://github.com/energy-models/math-spec/issues/216)) ([fab308f](https://github.com/energy-models/math-spec/commit/fab308f61fddfad230fe8fb9d11e3961faa0a704)), closes [#214](https://github.com/energy-models/math-spec/issues/214)
+* **language:** a link takes any affine expression, an uncalled template hides no typo, and degree is decided at load ([#91](https://github.com/energy-models/math-spec/issues/91)) ([a653056](https://github.com/energy-models/math-spec/commit/a6530562d59b4ac134ef4fd051ae1c9aea5f1b2c))
+* **language:** a negative edge fill prints, the sign of a literal amount being folded once at resolution ([#234](https://github.com/energy-models/math-spec/issues/234)) ([d9303db](https://github.com/energy-models/math-spec/commit/d9303dbd1e824f674331b7e9403dd5799444dd15))
+* **language:** a negative sum_back width is refused at load rather than asserting in lowering ([#223](https://github.com/energy-models/math-spec/issues/223)) ([62e52eb](https://github.com/energy-models/math-spec/commit/62e52eb6c7071f16e360055c5d11870e8a2ba1a0)), closes [#222](https://github.com/energy-models/math-spec/issues/222)
+* **language:** a where mask is folded at resolution, so a typeset page and a program agree about it ([#232](https://github.com/energy-models/math-spec/issues/232)) ([553bda0](https://github.com/energy-models/math-spec/commit/553bda0239932b8a1225a6df0f9d008dff5e285d))
+* **language:** the language reference states which case arms are refused, and the refusal says what actually breaks ([#336](https://github.com/energy-models/math-spec/issues/336)) ([01920d1](https://github.com/energy-models/math-spec/commit/01920d1be4f6dbd6965f6f0e7e683543384cc744))
+* let sum_back stop at each group's edge, as its checks already assumed ([#65](https://github.com/energy-models/math-spec/issues/65)) ([cb58e88](https://github.com/energy-models/math-spec/commit/cb58e885221484f41804b33d47b1004874565ae4))
+* **parser:** a negation is over a power, a keyword is given once, and an amount is a number or a name ([#88](https://github.com/energy-models/math-spec/issues/88)) ([4bf994c](https://github.com/energy-models/math-spec/commit/4bf994ce4700b634e970b49e8e10e705c479a65f))
+* **parser:** a parsed expression cannot be rewritten under another pass ([#329](https://github.com/energy-models/math-spec/issues/329)) ([fcfb7b8](https://github.com/energy-models/math-spec/commit/fcfb7b8a3e2c66cd03da316994154b9c2dd493d0))
+* **program:** a program describes a mathematical program rather than being one, and claims neither linearity nor a storage format ([#315](https://github.com/energy-models/math-spec/issues/315)) ([5dfa6be](https://github.com/energy-models/math-spec/commit/5dfa6be817fb49999571b2fdc8b8b820371f80d0))
+* **program:** a where mask cannot be rewritten under another consumer ([#197](https://github.com/energy-models/math-spec/issues/197)) ([ce406b0](https://github.com/energy-models/math-spec/commit/ce406b045567ff82732f818e2a905bf7d302852b))
+* **program:** an unknown dimension is refused rather than answered empty ([#199](https://github.com/energy-models/math-spec/issues/199)) ([96fdccf](https://github.com/energy-models/math-spec/commit/96fdccf105bf2ffc37d8cda078f3560e56bff9ec))
+* **program:** every expression node answers fan_in ([#202](https://github.com/energy-models/math-spec/issues/202)) ([f5cc67d](https://github.com/energy-models/math-spec/commit/f5cc67d9320ab254771e2d5527bf41641a6ca648))
+* refuse a negated named amount, and one read where there is no coordinate ([#63](https://github.com/energy-models/math-spec/issues/63)) ([15d9c25](https://github.com/energy-models/math-spec/commit/15d9c252e2126278f2547c9df399edf85bd44df3)), closes [#62](https://github.com/energy-models/math-spec/issues/62)
+* refuse a str or bool parameter where arithmetic wants a number ([#71](https://github.com/energy-models/math-spec/issues/71)) ([9b320fd](https://github.com/energy-models/math-spec/commit/9b320fd385d6300df3dadb14be4c9317a9241da0))
+* **schema:** every refusal of a malformed file is a SchemaError, and an empty declared map survives a round trip ([#89](https://github.com/energy-models/math-spec/issues/89)) ([ee07736](https://github.com/energy-models/math-spec/commit/ee07736babd79b2d0f5f99f6c9d7c25a2c98dc9f))
+* **schema:** two literal bounds that cross are refused at load ([#97](https://github.com/energy-models/math-spec/issues/97)) ([30589ba](https://github.com/energy-models/math-spec/commit/30589ba4bf61e640c8f3778e34d5bd768e807e2c))
+* stop prettier rewriting what release-please generates ([#27](https://github.com/energy-models/math-spec/issues/27)) ([7486555](https://github.com/energy-models/math-spec/commit/7486555f199f105d1cb6d29a141bbbd3cfedead2))
+* stop the release build silently shipping a 0.0.0 wheel ([#23](https://github.com/energy-models/math-spec/issues/23)) ([a801b00](https://github.com/energy-models/math-spec/commit/a801b00061d306661d31b455ed2980fd0dfbeda9))
+* the ac-dc-meshed rung states its network, so the reference run needs no download ([#166](https://github.com/energy-models/math-spec/issues/166)) ([abf734c](https://github.com/energy-models/math-spec/commit/abf734c8cd294935907455048a39da585cca56e1))
+* the linearized rung states its three caps as rows and starts one unit cold, so every block it declares is built ([#162](https://github.com/energy-models/math-spec/issues/162)) ([cb4863f](https://github.com/energy-models/math-spec/commit/cb4863f35f71a97c44703390335121200273a4f6))
+* the notation page is generated again, and something says so ([#41](https://github.com/energy-models/math-spec/issues/41)) ([3dad75e](https://github.com/energy-models/math-spec/commit/3dad75e136a91025c1d24cf1cdb13c4894c85c15))
+* the release notes landed inside an HTML comment ([#25](https://github.com/energy-models/math-spec/issues/25)) ([c33dc24](https://github.com/energy-models/math-spec/commit/c33dc241e12446f2433d600c7afc109063cd3656))
+* to_markdown printed TeX's em-dash ligature, not an em dash ([#34](https://github.com/energy-models/math-spec/issues/34)) ([226407a](https://github.com/energy-models/math-spec/commit/226407a9e0e08575041b32d388288ee456d231d3))
+* **typeset:** a string value in a where clause prints as a quoted label ([#114](https://github.com/energy-models/math-spec/issues/114)) ([9be22c1](https://github.com/energy-models/math-spec/commit/9be22c1f979c8d887e91cef302b2b63570fcbae0))
+* **typeset:** a sum under its own dimension takes a fresh index, and prose escapes its markup ([#92](https://github.com/energy-models/math-spec/issues/92)) ([20c7076](https://github.com/energy-models/math-spec/commit/20c7076511c5a3ef74dc06fe0d11888f292f1b2d))
+
+
+### Performance
+
+* **program:** a mask walks its leaves once and every question reads that walk ([#338](https://github.com/energy-models/math-spec/issues/338)) ([337d169](https://github.com/energy-models/math-spec/commit/337d1697724980356c8d911bf21242a19a6f517a))
+
+
+### Refactoring
+
+* a program is trusted by construction, so the language's rules are checked once, on the spec ([#189](https://github.com/energy-models/math-spec/issues/189)) ([45931b1](https://github.com/energy-models/math-spec/commit/45931b1a975d80faa45ad47303fdbb30b1f12855))
+* dead branches, an unused depth cap and prose about a parent project are gone ([#86](https://github.com/energy-models/math-spec/issues/86)) ([f31f3b0](https://github.com/energy-models/math-spec/commit/f31f3b00869131f587071a3ede24fa636cf175d7))
+* extract the language and typeset from lpspec ([#17](https://github.com/energy-models/math-spec/issues/17)) ([b997193](https://github.com/energy-models/math-spec/commit/b9971930a95a9b6c80938aaff0224d4a0f2e4ff3))
+* name the groups a pass asks about, and spell each operator once ([#52](https://github.com/energy-models/math-spec/issues/52)) ([e35c46c](https://github.com/energy-models/math-spec/commit/e35c46c128a29a620c9ed562684cf1dd43a08274))
+* one call returns every note the language can give without data ([#191](https://github.com/energy-models/math-spec/issues/191)) ([2face7a](https://github.com/energy-models/math-spec/commit/2face7a39092e5f2fc1ddb705efee8a7d34dd343))
+* **parser:** one number rule, one amount table, and a namespace nothing builds by hand ([#106](https://github.com/energy-models/math-spec/issues/106)) ([f775a07](https://github.com/energy-models/math-spec/commit/f775a07cf8f5159dd8df973f995b8dad87fd01ef))
+* **program:** a program is built by keyword, so a new field cannot reorder an old call ([#203](https://github.com/energy-models/math-spec/issues/203)) ([214394a](https://github.com/energy-models/math-spec/commit/214394a0dc2499b5af8c8300b2306631e9592f98))
+* **program:** a program's declarations are keyed by the name the file wrote ([#205](https://github.com/energy-models/math-spec/issues/205)) ([579264a](https://github.com/energy-models/math-spec/commit/579264a6b69557ab840edf38dace462e10b6715e))
+* **program:** drop the two pieces of the program API nothing reaches ([#204](https://github.com/energy-models/math-spec/issues/204)) ([ca25fa5](https://github.com/energy-models/math-spec/commit/ca25fa5433540d45b73bc9fe307eeca78bc47376))
+* **program:** expressions are the ones a row is built from, and the declared ones say so ([#206](https://github.com/energy-models/math-spec/issues/206)) ([81aaddd](https://github.com/energy-models/math-spec/commit/81aaddd655a8db6676f4f87c073908f6c0340a16))
+* **program:** the declaration vocabularies have one home, so a program cannot spell one differently from the file ([#219](https://github.com/energy-models/math-spec/issues/219)) ([f7596d7](https://github.com/energy-models/math-spec/commit/f7596d7bcf7ff61aff5a94807b34bf5516b29085)), closes [#209](https://github.com/energy-models/math-spec/issues/209)
+* **program:** the program module says what it promises, rather than offering its whole namespace ([#208](https://github.com/energy-models/math-spec/issues/208)) ([08d2f64](https://github.com/energy-models/math-spec/commit/08d2f644f1975aca0a3eb4927e034c402e6d46eb))
+* **schema:** one wording for an undeclared dimension, and the front door validates once ([#105](https://github.com/energy-models/math-spec/issues/105)) ([69e42db](https://github.com/energy-models/math-spec/commit/69e42db6f453b9caff349ddf109ee77aed3617fa))
+* the package is `typesetting`, the function stays `typeset` ([#54](https://github.com/energy-models/math-spec/issues/54)) ([a1d9599](https://github.com/energy-models/math-spec/commit/a1d95994333b25ac03f75f47eb2b376a03af6593))
+* the stack's own additions say less and repeat nothing ([#102](https://github.com/energy-models/math-spec/issues/102)) ([119e588](https://github.com/energy-models/math-spec/commit/119e5884a576264c38c8455c625908ee09d057c9))
+* the tree describes this package, not the project it was cut from ([#94](https://github.com/energy-models/math-spec/issues/94)) ([9673f9a](https://github.com/energy-models/math-spec/commit/9673f9aef6bc7902439d7842c83a3fd95c29895e))
+* two public states and a conversion to each, where the surface was seventy-seven names ([#180](https://github.com/energy-models/math-spec/issues/180)) ([718e2de](https://github.com/energy-models/math-spec/commit/718e2dea7c6e05933c4880196279ae9fe015dd09))
+* **typeset:** Markdown is LaTeX's math with its own document layer, and a step merges itself ([#107](https://github.com/energy-models/math-spec/issues/107)) ([1ca9178](https://github.com/energy-models/math-spec/commit/1ca9178b82f629bd39170e884b82265c7935b8de))

+### Documentation
+
+* a link's delivery lags its flow, wrapping or losing what is in transit at the horizon's edge ([#300](https://github.com/energy-models/math-spec/issues/300)) ([1d4f10f](https://github.com/energy-models/math-spec/commit/1d4f10fce6ef9889400caddd0cf0436ab2b07c53))
+* a named offset needs no edge=, the limitation it named is gone ([#68](https://github.com/energy-models/math-spec/issues/68)) ([d91a0c3](https://github.com/energy-models/math-spec/commit/d91a0c37803906848808c49310356004740b8172)), closes [#64](https://github.com/energy-models/math-spec/issues/64)
+* AGENTS.md says what a change here is held to ([#76](https://github.com/energy-models/math-spec/issues/76)) ([5e142f5](https://github.com/energy-models/math-spec/commit/5e142f5c9d41588bac44b9cce769995364f3a94a))
+* **agents:** the cheap gates run here, and CI is reported rather than watched ([#175](https://github.com/energy-models/math-spec/issues/175)) ([78e3d80](https://github.com/energy-models/math-spec/commit/78e3d80e0705238296a90e9eed3ecf182f737e2c))
+* an Examples section, each model beside the math it prints ([#38](https://github.com/energy-models/math-spec/issues/38)) ([66bfae4](https://github.com/energy-models/math-spec/commit/66bfae482a0ae9b1010b02d26e5316cf72da17dd))
+* **ceiling:** load-time unit checking has its own refusal, where the data-prep row used to answer for it ([#272](https://github.com/energy-models/math-spec/issues/272)) ([8dfd17d](https://github.com/energy-models/math-spec/commit/8dfd17df17993f1209fe479734c3dee756fcc384))
+* drop the effects row from the PyPSA-1.3.0 parity table, a feature that release does not have ([#305](https://github.com/energy-models/math-spec/issues/305)) ([92e5ed8](https://github.com/energy-models/math-spec/commit/92e5ed84c14c59e8068a7814722950f936e2925a))
+* **examples:** the PyPSA file states a constraint once where PyPSA builds one row set, rather than a block per regime ([#257](https://github.com/energy-models/math-spec/issues/257)) ([#292](https://github.com/energy-models/math-spec/issues/292)) ([c35e637](https://github.com/energy-models/math-spec/commit/c35e637c8632e361d1d9565824e0497d3199bc16))
+* **language:** a label space may group a position, though not a reduction or a walk ([#281](https://github.com/energy-models/math-spec/issues/281)) ([00be0cb](https://github.com/energy-models/math-spec/commit/00be0cb9bca7bc3f73860a50fe703d6eefff3be6))
+* **language:** the absence page is half the length and shows each rule on a model ([#127](https://github.com/energy-models/math-spec/issues/127)) ([147788a](https://github.com/energy-models/math-spec/commit/147788af0d8f912ed3442e56392b3ef3e994a7ed))
+* the absence rules cover every operator, not the three they named ([#173](https://github.com/energy-models/math-spec/issues/173)) ([3266a5b](https://github.com/energy-models/math-spec/commit/3266a5bbfb5df657f4a1a417f8ce5206ee986227))
+* the language knows nothing about sinks ([#118](https://github.com/energy-models/math-spec/issues/118)) ([886a854](https://github.com/energy-models/math-spec/commit/886a85458a977706ee773f53d8dd75cfbbd7e125))
+* the README's example of reading a loaded model runs as written ([#240](https://github.com/energy-models/math-spec/issues/240)) ([304a233](https://github.com/energy-models/math-spec/commit/304a233d408979aa54b7fa2b0a6b5f12469e8afd))
+* the style guide's front-door example is the function it quotes ([#187](https://github.com/energy-models/math-spec/issues/187)) ([5dbed70](https://github.com/energy-models/math-spec/commit/5dbed70024c1e59633ffcee0f4f6295abc69fd8c))
+* the title rules are written for the changelog reader ([#79](https://github.com/energy-models/math-spec/issues/79)) ([fdb52e4](https://github.com/energy-models/math-spec/commit/fdb52e49dcd69be775e4be3e1860f4339a6283af))
