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. Jurisdiction + +Without prejudice to specific agreement between parties, + +- any litigation resulting from the interpretation of this License, arising + between the European Union institutions, bodies, offices or agencies, as a + Licensor, and any Licensee, will be subject to the jurisdiction of the Court + of Justice of the European Union, as laid down in article 272 of the Treaty on + the Functioning of the European Union, + +- any litigation arising between other parties and resulting from the + interpretation of this License, will be subject to the exclusive jurisdiction + of the competent court where the Licensor resides or conducts its primary + business. + +15.

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 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.

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..777f211b --- /dev/null +++ b/tests/cli/v090-upgrade/audit.sh @@ -0,0 +1,762 @@ +#!/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.
