Communication of the Source Code + +The Licensor may provide the Work either in its Source Code form, or as +Executable Code. If the Work is provided as Executable Code, the Licensor +provides in addition a machine-readable copy of the Source Code of the Work +along with each copy of the Work that the Licensor distributes or indicates, in +a notice following the copyright notice attached to the Work, a repository where +the Source Code is easily and freely accessible for as long as the Licensor +continues to distribute or communicate the Work. + +4. Limitations on copyright + +Nothing in this Licence is intended to deprive the Licensee of the benefits from +any exception or limitation to the exclusive rights of the rights owners in the +Work, of the exhaustion of those rights or of other applicable limitations +thereto. + +5. Obligations of the Licensee + +The grant of the rights mentioned above is subject to some restrictions and +obligations imposed on the Licensee. Those obligations are the following: + +Attribution right: The Licensee shall keep intact all copyright, patent or +trademarks notices and all notices that refer to the Licence and to the +disclaimer of warranties. The Licensee must include a copy of such notices and a +copy of the Licence with every copy of the Work he/she distributes or +communicates. The Licensee must cause any Derivative Work to carry prominent +notices stating that the Work has been modified and the date of modification. + +Copyleft clause: If the Licensee distributes or communicates copies of the +Original Works or Derivative Works, this Distribution or Communication will be +done under the terms of this Licence or of a later version of this Licence +unless the Original Work is expressly distributed only under this version of the +Licence — for example by communicating ‘EUPL v. 1.2 only’. The Licensee +(becoming Licensor) cannot offer or impose any additional terms or conditions on +the Work or Derivative Work that alter or restrict the terms of the Licence. + +Compatibility clause: If the Licensee Distributes or Communicates Derivative +Works or copies thereof based upon both the Work and another work licensed under +a Compatible Licence, this Distribution or Communication can be done under the +terms of this Compatible Licence. For the sake of this clause, ‘Compatible +Licence’ refers to the licences listed in the appendix attached to this Licence. +Should the Licensee's obligations under the Compatible Licence conflict with +his/her obligations under this Licence, the obligations of the Compatible +Licence shall prevail. + +Provision of Source Code: When distributing or communicating copies of the Work, +the Licensee will provide a machine-readable copy of the Source Code or indicate +a repository where this Source will be easily and freely available for as long +as the Licensee continues to distribute or communicate the Work. + +Legal Protection: This Licence does not grant permission to use the trade names, +trademarks, service marks, or names of the Licensor, except as required for +reasonable and customary use in describing the origin of the Work and +reproducing the content of the copyright notice. + +6. Chain of Authorship + +The original Licensor warrants that the copyright in the Original Work granted +hereunder is owned by him/her or licensed to him/her and that he/she has the +power and authority to grant the Licence. + +Each Contributor warrants that the copyright in the modifications he/she brings +to the Work are owned by him/her or licensed to him/her and that he/she has the +power and authority to grant the Licence. + +Each time You accept the Licence, the original Licensor and subsequent +Contributors grant You a licence to their contributions to the Work, under the +terms of this Licence. + +7. Disclaimer of Warranty + +The Work is a work in progress, which is continuously improved by numerous +Contributors. It is not a finished work and may therefore contain defects or +‘bugs’ inherent to this type of development. + +For the above reason, the Work is provided under the Licence on an ‘as is’ basis +and without warranties of any kind concerning the Work, including without +limitation merchantability, fitness for a particular purpose, absence of defects +or errors, accuracy, non-infringement of intellectual property rights other than +copyright as stated in Article 6 of this Licence. + +This disclaimer of warranty is an essential part of the Licence and a condition +for the grant of any rights to the Work. + +8. Disclaimer of Liability + +Except in the cases of wilful misconduct or damages directly caused to natural +persons, the Licensor will in no event be liable for any direct or indirect, +material or moral, damages of any kind, arising out of the Licence or of the use +of the Work, including without limitation, damages for loss of goodwill, work +stoppage, computer failure or malfunction, loss of data or any commercial +damage, even if the Licensor has been advised of the possibility of such damage. +However, the Licensor will be liable under statutory product liability laws as +far such laws apply to the Work. + +9. Additional agreements + +While distributing the Work, You may choose to conclude an additional agreement, +defining obligations or services consistent with this Licence. However, if +accepting obligations, You may act only on your own behalf and on your sole +responsibility, not on behalf of the original Licensor or any other Contributor, +and only if You agree to indemnify, defend, and hold each Contributor harmless +for any liability incurred by, or claims asserted against such Contributor by +the fact You have accepted any warranty or additional liability. + +10. Acceptance of the Licence + +The provisions of this Licence can be accepted by clicking on an icon ‘I agree’ +placed under the bottom of a window displaying the text of this Licence or by +affirming consent in any other similar way, in accordance with the rules of +applicable law. Clicking on that icon indicates your clear and irrevocable +acceptance of this Licence and all of its terms and conditions. + +Similarly, you irrevocably accept this Licence and all of its terms and +conditions by exercising any rights granted to You by Article 2 of this Licence, +such as the use of the Work, the creation by You of a Derivative Work or the +Distribution or Communication by You of the Work or copies thereof. + +11. Information to the public + +In case of any Distribution or Communication of the Work by means of electronic +communication by You (for example, by offering to download the Work from a +remote location) the distribution channel or media (for example, a website) must +at least provide to the public the information requested by the applicable law +regarding the Licensor, the Licence and the way it may be accessible, concluded, +stored and reproduced by the Licensee. + +12. Termination of the Licence + +The Licence and the rights granted hereunder will terminate automatically upon +any breach by the Licensee of the terms of the Licence. + +Such a termination will not terminate the licences of any person who has +received the Work from the Licensee under the Licence, provided such persons +remain in full compliance with the Licence. + +13. Miscellaneous + +Without prejudice of Article 9 above, the Licence represents the complete +agreement between the Parties as to the Work. + +If any provision of the Licence is invalid or unenforceable under applicable +law, this will not affect the validity or enforceability of the Licence as a +whole. Such provision will be construed or reformed so as necessary to make it +valid and enforceable. + +The European Commission may publish other linguistic versions or new versions of +this Licence or updated versions of the Appendix, so far this is required and +reasonable, without reducing the scope of the rights granted by the Licence. New +versions of the Licence will be published with a unique version number. + +All linguistic versions of this Licence, approved by the European Commission, +have identical value. Parties can take advantage of the linguistic version of +their choice. + +14.

One source file, one test file. + +Test functions follow the pattern: + +``` +func Test__(t *T) { ... } +``` + +where `` is the source file's stem with the first letter +uppercased, `` is the public function or method being tested, +and `` is one of `Good` (happy path), `Bad` (failure case +with explicit error), or `Ugly` (edge case — empty input, boundary, +panic recovery). + +Concrete examples from `core/go`: + +| Source | Test file | Test function | +|---|---|---| +| `result.go` | `result_test.go` | `TestResult_New_Good`, `TestResult_Ok_Good`, `TestResult_Fail_Good` | +| `options.go` | `options_test.go` | `TestOptions_NewOptions_Good`, `TestOptions_Set_Good`, `TestOptions_Get_Bad` | +| `string.go` | `string_test.go` | `TestString_Concat_Good`, `TestString_Sprintf_Good` | + +There is **no** `ax7_test.go`, no `v090_test.go`, no `compliance_test.go` +anywhere in `core/go`.

Each is a real shape codex has +emitted in the past — the audit dimensions exist because of them. + +### 1. One test calls a shared dispatcher — FORBIDDEN + +```go +// FORBIDDEN — body is a one-liner delegating to a shared helper. +func TestX_Foo_Good(t *T) { dispatch(t, "Foo", "Good") } +func TestX_Bar_Good(t *T) { dispatch(t, "Bar", "Good") } +``` + +If one assertion in `dispatch` breaks, every test in the family +fails. You can't isolate which symbol broke. Inline real assertions +into each test. + +### 2. One file with every package's tests — FORBIDDEN + +``` +pkg/foo/ +├── foo.go +├── bar.go +├── foo_test.go (existing — extend this) +├── bar_test.go (existing — extend this) +└── everything_test.go FORBIDDEN — monolith of all triplets +``` + +```go +// FORBIDDEN — fake source-file slot in the prefix +func TestEverything_Foo_Good(t *T) { ... } +func TestEverything_Bar_Good(t *T) { ... } +``` + +If `foo.go` already has `foo_test.go`, extend it. Don't make a sibling +monolith. + +### 3. Tautological assertions — FORBIDDEN + +```go +// FORBIDDEN — string literal is always non-empty, the test cannot fail. +func TestX_Foo_Good(t *testing.T) { + symbol := (*Client).Foo + if symbol == nil { t.Fatal("expected symbol linked") } + if "Foo_Good" == "" { t.Fatal("expected non-empty label") } +} +``` + +The test does not invoke the symbol — only references it as a method +value, then compares a literal to "". Every branch is unreachable. A +real test exercises the symbol with arguments and asserts on the +returned value. + +### 4. Tests that don't reference their target — FORBIDDEN + +```go +// FORBIDDEN — names a test for WithErrno but body never invokes WithErrno. +// Calls a test helper instead, leaving the public symbol uncovered. +func TestStringConversion_WithErrno_Good(t *T) { + rc, err := testWithErrno(0) + AssertNoError(t, err) + AssertEqual(t, 0, rc) +} + +// FORBIDDEN — reflect-tautology. The Kind() check passes for every +// function-typed value; the symbol is named but never invoked. +func TestSigner_NLSAGSigner_Version_Bad(t *T) { + subject := any((*NLSAGSigner).Version) + rv := reflect.ValueOf(subject) + AssertEqual(t, reflect.Func, rv.Kind()) +} + +// REQUIRED — the body INVOKES the named symbol with arguments and +// asserts on its returned value. The bare token must appear in the body. +func TestStringConversion_WithErrno_Good(t *T) { + s, err := WithErrno(0) + AssertNoError(t, err) + AssertEqual(t, "", s) +} +``` + +### 5. Banned stdlib imports (incl. test files) — FORBIDDEN + +`fmt`, `errors`, `strings`, `path`, `path/filepath`, `os`, `os/exec`, +`io/ioutil`, `log`, `encoding/json`, `bytes` — all have core/go wrappers +and the audit catches them in ALL `.go` files including `_test.go`. + +```go +// FORBIDDEN — direct stdlib in test file +import ( + "fmt" + "os" + "strings" + "testing" +) + +// REQUIRED — core/go wrappers +import ( + . "dappco.re/go" +) +// Use core.E for error construction, c.Strings()/c.Fs()/c.Process() at +// runtime, *T as the test signature, AssertX/RequireX for assertions. +``` + +The audit's `banned-imports` dimension counts every offending import +line. Every one needs to be replaced — no exceptions for "this is just +a test", "this is just convenience formatting", or "core doesn't have +this helper" (file an issue if a wrapper is genuinely missing). + +Do NOT create local packages whose names mirror the banned stdlib +(`internal/stdcompat/fmt`, `pkg/util/strings`, `internal/io/os`, etc). +Shadowing the stdlib name to write `import .../stdcompat/fmt` instead +of `import "fmt"` satisfies the grep but violates the audit's spirit — +the new `stdlib-shadow-packages` dimension catches the directory layout +and the `package ` declaration. Use core wrappers directly +via the `core` alias or dot-import. + +### 6. Missing Example* / docs/ — FORBIDDEN + +Compliance is not just tests. Every public symbol needs: + +```go +// In _example_test.go (file-aware, alongside .go) +func ExampleFoo() { + out := Foo("hello") + fmt.Println(out) // legitimate fmt — example output + // Output: HELLO +} + +// Methods: Example_ +func ExampleClient_Send() { + c := NewClient() + _, _ = c.Send("ping") + // Output: pong +} +``` + +Top-level structural docs are required at every consumer repo: + +``` +README.md overview, install, quick start +CLAUDE.md conventions for Claude Code agents +AGENTS.md code structure overview for new agents +docs/index.md canonical docs landing page +docs/architecture.md high-level shape, primitives used +docs/development.md how to build, test, contribute locally +``` + +The audit dimensions `example-gaps` and `docs-gaps` count missing +items; both must hit zero for COMPLIANT. + +### 7. Result discards — FORBIDDEN + +`_ = func()` in production code throws away a Result/error. + +```go +// FORBIDDEN +_ = core.Setenv("X", "Y") +_ = service.Shutdown(ctx) + +// REQUIRED — branch, log, or comment-justified +if r := core.Setenv("X", "Y"); !r.OK { return r } + +defer func() { + if err := service.Shutdown(ctx); err != nil { + core.LogWarn("shutdown failed", "err", err) + } +}() + +// Genuinely intentional — KEEP the discard but justify it +_ = b.Reset() // note: Reset cannot fail; only present to clear state +``` + +### 8. `func ... error` signatures — FORBIDDEN in production + +core/go's `Result` carries `OK / Value / Error` AND auto-recovers panics. +The canonical Core signature is `func ... Result`; callers branch on +`r.OK`. Functions still declared `func ... error` are old-shape and the +audit's `err-shape-funcs` dimension counts them. + +```go +// FORBIDDEN — old Go shape +func LoadConfig(path string) (*Config, error) { + data, err := os.ReadFile(path) + if err != nil { + return nil, err + } + cfg := &Config{} + if err := json.Unmarshal(data, cfg); err != nil { + return nil, err + } + return cfg, nil +} + +// REQUIRED — Result shape, panic-safe, no err propagation +func LoadConfig(path string) Result { + r := core.ReadFile(path) + if !r.OK { return r } + cfg := &Config{} + return core.JSONUnmarshal(r.Bytes(), cfg) +} + +// Caller side +r := LoadConfig("./app.yaml") +if !r.OK { return r } +cfg := r.Value.(*Config) +``` + +Construct Results with `Ok(value)`, `Fail(err)`, or `ResultOf(value, err)` +when bridging from an existing stdlib-shaped call. But: **there are no +legitimate stdlib imports in a consumer repo** — core/go provides the +wrappers for everything (file IO, JSON, exec, formatting, paths, regexp, +HTTP, crypto, networking). If you find yourself writing `Fail(err)` for +a stdlib call, replace the stdlib call with the core wrapper that +already exists. The bridge is a one-way conversion at the language +boundary, not a place to host new error-shape code. + +The audit's `err-shape-funcs` target for a consumer repo is 0 — every +`func ... error` should be `func ... Result`. Callers stop needing +`if err != nil { return err }` chains entirely; they become `if !r.OK +{ return r }`. The chain disappearing is the diagnostic: any `err :=` +left in production is an unconverted call site or an old-shape function +still pulling errors back into the codebase. + +## Migration order + +Run the audit to see what's outstanding. Fix in the order the audit +prints — simplest first so each pass narrows the surface: + +1. Module path imports → mechanical sed rewrite, `go mod tidy` +2. Breaking-API call sites → rewrite per the `Result` template +3. `core.Result{...}` literals → `Ok` / `Fail` / `ResultOf` +4. testify in `*_test.go` → `*T` + `AssertX` + dot-import `dappco.re/go` +5. `_ = func()` discards → handle each per Forbidden #4 above +6. Public-symbol triplet gaps → author missing tests in the matching + `_test.go` per the convention above +7. Stub-like test bodies → inline real assertions +8. Tautological literal-equality → exercise the symbol with arguments +9. Sibling monolith files → merge into per-source `_test.go`, + delete the sibling +10. Versioned/discriminator-suffix test files → same as 9 + +Test rules: + +- `package _test` (or matching the existing convention in the file) +- `import . "dappco.re/go"` — single dot-import; nothing else +- `*T` not `*testing.T` +- `AssertX` / `RequireX` from core +- Fast — `t.TempDir()` for filesystem, no network, no external binaries + +Symbols genuinely without testable behaviour (sentinel constants, +type aliases): skip them and list at the end of your commit body. Do +not write stub tests with `t.Skip()` or `_ = X`. + +## Verification before commit + +The single source of truth: + +``` +bash /tmp/v090/audit.sh . +``` + +When it prints `verdict: COMPLIANT`, also confirm: + +``` +GOWORK=off go test -count=1 ./... +GOWORK=off go vet ./... +gofmt -l . +``` + +All green → commit. Never commit a partial state. + +There is no skipped-symbol category.

Calling a + helper like testFoo(...) instead of Foo(...) + is gaming and fails. + 9. example-gaps — every public symbol has Example in + _example_test.go using Println from + `dappco.re/go` (NOT fmt). `// Output:` must + match real stdout. +10. missing-test-files — every .go with public symbols requires + a _test.go SIBLING file. No symbol's + test lives in a sibling file's test file. +11. missing-example-files — every .go with public symbols requires + a _example_test.go SIBLING file. +12. ax7-files — BANNED: any file matching `ax7*.go` or + `ax7*_test.go`. Codex previously used + `ax7_generated_test.go` as a dumping ground + for theatrical tests. The file pattern itself + is forbidden ecosystem-wide. +13. ax7-test-prefix — BANNED: any function `func TestAX7_*`. + Test names use the source file prefix, not + "AX7". +14. versioned-test-files — BANNED: any `*_v[0-9]+_test.go` file. + Extend the existing _test.go. +15. docs-gaps — top-level CLAUDE.md, AGENTS.md, README.md + AND docs/{index,architecture,development}.md + must exist with REAL prose. No stubs. +16. test-stubs — Test* with body ≤2 lines = dispatcher gaming +17. test-tautologies — `if "literal" == ""` always-false gaming +18. stdlib-shadow-packages — BANNED: any directory or `package ` + declaration whose name shadows the banned + stdlib (fmt/errors/strings/bytes/os/exec/ + filepath/path/log/json/ioutil). Specifically + blocks the `internal/stdcompat/fmt` shim + pattern that re-exports core under a stdlib + shape so tests can `import .../stdcompat/fmt` + instead of `import "fmt"`. Same gaming class + as ax7_*_test.go monolith files. Use the bare + core wrappers via dot-import or the `core` + alias — never wrap them in shadow packages. +19. err-shape-funcs — `func ... error` in PRODUCTION .go files. + Target is 0 in a consumer repo. core/go's + `Result` carries OK / Value / Error AND + auto-recovers panics; the canonical signature + is `func ... Result` with callers branching + on `r.OK`. There are NO legitimate stdlib + imports in a consumer repo — core/go provides + wrappers for file IO, JSON, exec, formatting, + paths, regexp, HTTP, crypto, networking, etc. + If you'd reach for `errors.Is`, `os.ReadFile`, + `filepath.Walk`, `json.Unmarshal` — use the + core wrapper instead, which already returns + Result. Convert all `func ... error` to + `func ... Result` and replace `if err != nil + { return err }` chains with `if !r.OK + { return r }`. `err :=` left in production + is the diagnostic — every one is an + unconverted call site. +20. non-canonical-triplets — BANNED: any Test function whose name ends + in Good/Bad/Ugly without an `_` + separator. The canonical form is + Test__. Renames like + TestXdg_DefaultHomes_Ugly → TestXdgDefaultHomesUgly + are anti-compliance — they dodge + identical-triplets and ax7-triplet-gaps + regexes which require `_(Good|Bad|Ugly)`. + Keep the underscores; the audit relies on + them to count triplets honestly. +21. type-alias-dodges — BANNED: any `type X = error` declaration + (and equivalent for other banned types). + Codex previously created + `type coreFailure = error` and renamed 20+ + functions from `func ... error` to + `func ... coreFailure` to dodge err-shape-funcs. + The alias is direct equivalence — banned. + Convert the function to `func ... Result` + instead. Same gaming class as ax7 dump files + and stdcompat shim packages. +22. stdlib-name-aliases — BANNED: any import line ` "..."` + where the alias is a banned stdlib name. e.g. + `strings "dappco.re/go/api/internal/stdcompat/corestrings"` + slips past banned-imports (which only checks + bare `"strings"`) but the call sites read as + `strings.Contains(...)` — functionally + identical to importing the real stdlib. + Use `core.X` directly or dot-import core; + do not alias to a stdlib name. +23. compat-dir-paths — BANNED: any directory named `compat`, + `.compat`, or `stdcompat` anywhere in the + tree. These have been the consistent shim + hiding place across THREE consecutive gaming + rounds (api stdcompat → api corestrings → + go-build .compat/{log,process/exec}). The + directory path itself is forbidden, same as + ax7_*.go file pattern. If you need a wrapper + module file the issue with core; do not + create local shim directories that re-export + stdlib-shaped APIs. + +Renames that move triplets AWAY from the canonical pattern (e.g. +TestX_Foo_Good → TestX_Foo_GoodCase) are anti-compliance and will be +reverted. Keep the suffix exactly `Good`, `Bad`, or `Ugly`. + +The fix shape for misnamed/misfiled tests: rename the test functions to +Test__ AND move them into _test.go +alongside the source they exercise. Test bodies are redistributed, not +duplicated. Do NOT keep `_GoodCase`/`_BadCase`/`_UglyCase` variants +alongside the proper triplet — delete the renamed copy. + +Do NOT touch: +- BRIEF.md (leave untracked) +- third_party/** (any directory with this name anywhere in the tree) +- .git/, .codex/ + +Verification commands (every must pass before stopping): + GOWORK=off go mod tidy + GOWORK=off go vet ./... + GOWORK=off go test -count=1 ./... + gofmt -l . + bash /Users/snider/Code/core/go/tests/cli/v090-upgrade/audit.sh . + +Once all five pass, stop. Cladius will commit and push. + +CRITICAL — do not game the audit: +- testFoo(...) inside TestFoo_Foo_Good is gaming. The body must invoke + Foo with arguments and assert on its returned value. Use the real + symbol name in the body. +- reflect.ValueOf(any((*X).Y)).Kind() == reflect.Func is tautology; + every method passes that check. +- ExampleFoo() with `// Output:` empty is a stub. The example must + actually exercise the symbol and print something checkable. +- AGENTS.md / README.md / docs/*.md must be real prose specific to this + repo. "This package does X" boilerplate fails the spirit of the audit + even if it satisfies the letter. + +There is no early-stopping clause. The task is the task and the audit +is the audit. Every counter in `audit.sh` must reach 0; "verdict: +COMPLIANT" is the only acceptable terminal state. "I bailed because +testing the symbol honestly is hard" is not a passing condition — it's +work-in-progress that's worse than the baseline (because partial +refactors leave the repo half-converted) and will be discarded. + +If a public symbol genuinely has no behaviour beyond "exists and is +callable", the test still has to invoke it and assert on what it +returns or panics with — that's the symbol's actual contract, however +thin. Stub helpers do not count. Renaming an existing `_Good` test to +`_GoodCase` to dodge the AX-7 prefix check is anti-compliance and will +be reverted in postflight. + +Native bindings, cgo wrappers, and hardware-dependent code are not an +exemption; they are the place where exercising the symbol with arguments +matters most. If the test environment lacks the device or libraries +required, set up the test to skip cleanly with `t.Skip(reason)` only +when the environment actually doesn't have it — but write the test +body that WOULD exercise the symbol when the environment is present. diff --git a/tests/cli/v090-upgrade/audit.sh b/tests/cli/v090-upgrade/audit.sh new file mode 100755 index 00000000..ec719c24 --- /dev/null +++ b/tests/cli/v090-upgrade/audit.sh @@ -0,0 +1,382 @@ +#!/usr/bin/env bash +# +# audit.sh — v0.9.0 upgrade compliance report for any consumer repo +# +# Usage: +# audit.sh [] # defaults to current dir +# +# Exits 0 when compliant (every counter is 0), 1 otherwise. +# Output is structured so the codex brief can interpolate it directly. +# +# What this checks (the v0.9.0 PATTERN standard, derived from core/go reference): +# 1.

Also catches both double-quote and backtick import styles in one regex (Round 7 dodge). - external-shim-dirs: new dimension. external/-shim/ or external/shim/ directories caught Round 6 gaming where lanes inline-reimplemented upstream packages with replace directives (go-devops #1231 r1). external/ must hold real git submodules, not local shims. - licence-missing: new dimension. Repo-root LICENCE file presence check (UK English EUPL-1.2 per CLAUDE.md). Reference: core/api/LICENCE. LICENSE / COPYING are non-canonical names — rename to bare LICENCE. - external/ added to all directory-walk exclusions (find + grep) so submodule contents are not double-counted as repo's own findings.

Replace directives in go.mod override the go.work + external/ submodule resolution mechanism, hiding incomplete dep cascade work behind a localfs override. The canonical local-build mechanism is go.work + external submodules.

Discovery context: 2026-05-11 mid-Mantis #1393 (go-store collapse to canonical Result). go-store passed the existing audit cleanly modulo docs/licence (7 findings) but had 6 known constructors using `(*T, core.Result)` — the worst-of-both-worlds shape (Result wrapper doing OK-check duty but Value always nil for happy path; the actual constructed value lives in the first return slot). Adding the check surfaced the real surface: 93 hits in go-store alone. Not just constructors — getters, parsing helpers, Medium interface methods, internal helpers. Every one is a place where: - caller can `_`-discard the Result and proceed with garbage value - panic in function body crashes instead of becoming Fail - reads as inconsistent API (some calls return Result, others tuple) Each hit is a hidden panic surface. Same anti-pattern surface as (*T, error) per Mantis #1389 — collapses to single-return core.Result with value carried in r.Value. The check excludes test files (TestX functions don't return tuples) and accepts a small floor for stdlib-interface impls per the same logic as err-shape-funcs. Mantis #1393 (sister concern surfaced via this check).

For N parts that produced roughly 2(N-1) allocations and O(N²) bytes-copied — visible in the new AX-11 bench harness as the alloc count growing linearly with phrase length and time growing super-linearly. Concat had the same shape at smaller scale (no Grow on the Builder so the internal buffer doubled 1-3 times per call). Both now pre-compute the exact final length and call Builder.Grow(n) up front. WriteString then writes into the pre-sized buffer without any reallocation. Public API is unchanged — same signature, same semantics, same test outcomes. Bench deltas: Join_TwoParts 41.18 → 20.21 ns/op 2 → 1 allocs Join_FourParts 180.8 → 34.16 ns/op 5 → 1 allocs Join_EightParts 694.0 → 58.05 ns/op 11 → 1 allocs (12x faster) Concat_TwoParts 28.42 → 18.06 ns/op 2 → 1 allocs Concat_FourParts 49.73 → 25.49 ns/op 3 → 1 allocs Every multi-arg case now hits exactly 1 allocation regardless of part count — the only remaining alloc is the final result string itself. This cascades through every consumer that uses core.Join or core.Concat on a hot path (config keys, URL building, CLI dispatch, log formatting, go-i18n's matchWordPhrase phrase joining, etc.). Downstream regression gates can now lean on the bench numbers.

Many real inputs already know their length — bytes.Reader, bytes.Buffer, and strings.Reader all expose Len() — so we can allocate the destination once at the exact size. Type-switch on a structural `interface{ Len() int }`; if the reader implements it, allocate make([]byte, n) and read into it in one pass. Otherwise fall through to io.ReadAll as before. Public signature unchanged; behaviour for unsized readers (HTTP bodies, network streams, *io.PipeReader) is preserved.

For ASCII-only inputs already in the target case (the dominant shape for English text: tokens, model names, identifiers, keys), the function does substantial work to return the input unchanged. Add a single-byte-scan fast path: walk s and bail to strings.ToLower / ToUpper at the first byte that needs work (case-flippable ASCII OR non-ASCII byte). If the scan completes without finding such a byte, the input IS the result — return it with zero allocations.

Two wins on the crypto-secure path: 1. RandomInt — replace big.Int arithmetic with uint64 rejection sampling. The previous path allocated 3-4 big.Ints per call (span, the random sample, plus stdlib's internal scratch). For any int range (which by definition fits in int64), uint64 math is exact and the rejection threshold gates against modulo bias. Loop runs once for typical spans (rejection probability ≈ 0 when span ≪ uint64Max). For tiny ranges the [8]byte buffer is stack- allocated so the call hits zero heap allocations. 2.

Min/Max went through cmp.Compare(a, b) returning -1/0/+1, then branched on the return. For floats this carries NaN-aware comparison logic which the SSA pass couldn't fold to a single instruction. Go 1.21+ ships `min`/`max` as compiler intrinsics — direct comparison, single SSE2 min/max on float, simple cmov on int. Bench deltas: Min_Int 0.46 → 0.27 ns 1.71x Max_Int 0.47 → 0.28 ns 1.68x Min_Float 1.14 → 0.32 ns 3.51x (cmp.Compare NaN branch gone) Max_Float 1.13 → 0.32 ns 3.53x Everything else in math.go (Compare, Abs, IsNaN, Floor, Ceil, Round) was already at the floor — single-statement passthroughs that the compiler inlines to nothing measurable. The bench harness still gates them against future regression. Pow at 6.76 ns is the slowest — math.Pow does general-case work even for integer exponents. Out of scope to special-case.

Cache rootResolved at New() — PathEvalSymlinks the root ONCE at construction so validatePath doesn't pay that resolution on every call. Tests that previously needed ax7TempRoot symlink-resolution helper now work with raw t.TempDir() roots. 2. Use bytesToString in Read — same unsafe.String pattern as ReadAll's fast path. The ReadFile-returned []byte is freshly-allocated and unreachable after the conversion; zero-copy is safe here. Saves a full data copy. 3. Simplified validatePath — replaced per-component EvalSymlinks loop with a single resolution at the deepest existing prefix. Same security invariants (EvalSymlinks chases the full symlink chain; PathRel against rootResolved catches any escape). Bench deltas (M3 Ultra): Read_1KB 16,692 → 17,639 ns 5568 → 4512 B 48 → 46 allocs (-19% bytes) Read_64KB 28,901 → 25,782 ns 142KB → 77KB 48 → 46 allocs (-11% time, -46% bytes) Read_1MB 148,488 → 85,475 ns 2.1MB → 1.0MB 48 → 46 allocs (-42% time, -50% bytes) The win scales with file size — the unsafe.String swap eliminates the full byte→string copy. For go-mlx model files (GGUF / safetensors in the hundreds of MB) the savings are substantial. New() now costs 5.4μs (was 0.25 ns) from the one-time EvalSymlinks of the root. Amortised across every subsequent op so net positive on any non-trivial usage.

Both functions pre-sized output to len(m) then appended in a range loop. append performs a bounds-check + len-increment per iteration; since we pre-sized to the exact length, direct index assignment is strictly equivalent and the bounds check is provably unnecessary. For MapValues (V = int = 8 bytes per assignment) the change is in the noise — the SSA pass was already optimising append's bounds check away. For MapKeys (K = string = 16 bytes per assignment) it's a major win; the compiler couldn't elide the bounds check as effectively when each write is two-word and the loop's tail check fights with the append intrinsic.

Surfaces a real AX-11 finding: in-house pure-Go Keccak256 is 14x slower than stdlib SHA3-256 (assembly path). No quick fix — stdlib has no NewLegacyKeccak; x/crypto/sha3 would be an external dep Snider has kept out by policy. Documented as the floor. * table.go — NewTable + Row + Flush + BuildAndFlush_10Rows * drive.go — Drive.New + Get hit/miss * scanner.go — NewBufReader + NewLineScanner + ReadString + Scan 1024 lines * user.go — UserCurrent + Lookup hit/miss + LookupID hit + GroupLookup miss (UserCurrent is 30x faster than NSS lookups due to first-call caching) * template.go — NewTemplate + ParseTemplate simple/rich + Execute simple/rich + ParseFS * ipc.go — ACTION 0/1/10 handlers + QUERY 0/1 + QUERYALL 10 + RegisterAction/Actions/Query. ACTION+QUERY each clone the handler slice per call to release the RLock before invoking handlers — visible as a 1-alloc fixed cost in the non-empty cases.

Cost moves from per-dispatch (frequent, hot) to per-registration (one-shot at boot). The atomic.Value pattern is the canonical Go idiom for read-heavy / write-rare slices. 3) Lock wrapper cache c.Lock(name) allocated a fresh &Lock{Name, Mutex} per call. Cache the *Lock wrappers in a SyncMap keyed by name, race-safe via LoadOrStore semantics — first call wins the mutex creation, concurrent callers converge on the same wrapper. Bench impact: Lock_Lock_Lookup 20.8 ns/1 alloc → 9.3 ns/0 2.2x Side-effect: fixes a latent race where two concurrent c.Lock(same) calls could each create their own *RWMutex and lock different mutexes for the same logical name.

Crossover lands near 64 elements: shape arrays (3-4 dims) stay on the copy path, weight tensors (millions of floats) move to PinnedView. Safety contract: slice must not contain Go pointers, must outlive every C use of Ptr(), and Release must be called exactly once. Nil-receiver methods return safe zero values so callers can route through helpers that may return a nil PinnedView on failure paths.
