Never weaken a security default. rejectTraversal, rejectSymlinks, + onDuplicate, every ZipLimits bound, and the CLI's extraction-sink + containment stay as they are unless a human records the decision. +6. No anti-goals. Do not propose encryption, other archive formats, + multi-disk archives, archive repair, or filesystem/network I/O inside the + engine — these are documented non-goals. +7.

The CLI is a thin, composable dispatch layer over it: **no ZIP +parsing logic in `src/`** — every byte-level operation (EOCD, central directory, local +headers, CRC, DEFLATE, path sanitisation) is a core call through `src/core-bridge/`. Raw +ZIP bytes are hand-written only in `scripts/` (corpus canaries, vendored validator) and +`tests/helpers/raw-zip-builder.ts` (hostile fixtures), and both are engine-independent by +construction. The CLI is offline, always: no command can open a socket. + +**Targets:** Node.js ≥ 22. The package is a CommonJS bin (`dist/cli.cjs`, the only build +artefact — no ESM build, no `.d.ts`, no programmatic entry point). Ubuntu 22/24 and Windows 22/24 +are blocking in CI (path separators, reserved device names, case-insensitive filesystems, CRLF); +macOS 22 runs too. + +## Working Modes & Token Economy + +Default to the cheapest mode that fits the request.

Governance & Human-in-the-Loop — `govern` + +The zipnative ecosystem's governance model treats AI agents as **draftsmen**, +never autonomous submitters.

Produce a **local draft** plus a compliance report and hand it + to the human. +- **Zero runtime dependencies.** Never propose adding an npm runtime package — this is a + hard block that `verify-issue` enforces. +- **No anti-goals.** Do not propose encryption, other archive formats, multi-disk + archives, archive repair, or filesystem / network I/O inside the engine + (`verify-issue` warns). +- **Never weaken a security default.** `rejectTraversal`, `rejectSymlinks`, + `onDuplicate`, every `ZipLimits` bound, `--max-input-size`, the extraction-sink + containment (lexical and physical), the exclusive-open overwrite policy, the + `modify` survivor verification and the `--codec` argv-only rule stay as they are unless + a human records the decision. Bytes under `--deterministic` are a frozen contract (a + byte change is semver-major). +- **Local reproduction required.** A bug draft must include a minimal, executed repro + inside a fenced code block; `verify-issue` fails the draft otherwise. +- **Identity integrity.** Anything submitted is published under the **human's** GitHub + identity; remind them of their shared responsibility. + +`govern verify-issue` returns `{ ok, errors, warnings }` under `--json`. A passing check is +**necessary but not sufficient** — the human review gate always applies. Recommended flow: +draft locally → `govern verify-issue` → present to the human → the **human** submits. +The printed rules and the policy JSON are pinned to `.github/AGENT_RULES.md` and +`.github/ai-governance.json` by a test, so what `govern` prints is what the repository +enforces. + +--- + +## 7. Recommended agent loop + +1. `zipnative doctor --format json` → confirm the CLI, Node ≥ 22 and the engine are + present, the deflate tier is `node-zlib`, workers are available if you plan + `create --parallel`, and read the **effective limits** as numbers from the + `limits` check's `data` (incl. `maxInputSize`). +2. `zipnative inspect --input a.zip --json --summary` → cheap facts (entries, bytes, + encrypted count, reproducibility and layout verdicts, diagnostics count) before + touching anything. Add `--check safe-names,no-encryption,no-symlinks,max-ratio=100` to turn + policy into an exit code. +3. `zipnative extract --input a.zip --output-dir out/ --dry-run --json` → the plan: + every destination proven safe, existing files refused, `skipped` inventory, + nothing written. Extract into an empty directory. +4. `zipnative extract --input a.zip --output-dir out/ --json` → do it; read the status + envelope from stderr. +5. On any non-zero exit, take the last stderr line that starts with `{`, branch on + `error.code`, and apply `error.remedy` (the CLI flag that lifts the refusal — + e.g. `--skip-unsafe`, `--on-duplicate first`, `--overwrite`) only for trusted input + (class) then `error.zipCode` (cause): `E_SECURITY` → quarantine the archive; + `E_LIMIT` → only for trusted input, retry with the named `--max-*` (or + `--max-input-size`) raised; `E_UNSUPPORTED` → route around the feature + (`detail.feature`, `--skip-unsupported`); `E_PARSE` / `E_DATA` → the bytes are + corrupt or hostile, re-obtain them; `E_IO` → an existing file (`--overwrite`) or a + filesystem problem; `E_NOT_FOUND` → `list` for the exact names. + +For `verify` / `inspect`, read the JSON result on stdout and use `--strict` / +`--check` to turn findings into exit codes for unattended gating; `verify --entry +` verifies a selection without paying for the whole archive. Add +`--summary` (or `--fields`) to keep that stdout JSON token-cheap — see §3. + +**Conformance changes → veraZIP gate.** An agent working **on this repository** must +run `npm run validate:zip` for any change touching what the CLI writes (`create`, +`modify`, `batch --task create`, the corpus generator, name handling): it builds the +CLI, drives the built binary to write the 37-archive corpus (33 conformant archives — +30 CLI-produced or crafted, plus 3 hostile-but-conformant ones `extract` must refuse — +and 4 raw-crafted negative canaries; expected `33 PASS, 4 XFAIL, 0 FAIL`) and +validates every file against ISO/IEC 21320-1:2015 with an engine-independent parser. +Level 0 needs no external tool and always runs; level 1 (foreign integrity tools) +skips visibly when a tool is absent — set `VERAZIP_REQUIRED=1` to fail closed as CI +does.

Under `--json` +every task that produces an artefact must name an `output`, and report-producing +tasks should ask for `"format": "json"` so their result lands in `tasks[i].report` +as an object rather than in `tasks[i].stdout` as text: + +```json +{ "version": 1, "tasks": [ + { "id": "build", "command": "create", "flags": { "input": "dist", "output": "release.zip", "deterministic": true, "overwrite": true } }, + { "id": "check", "command": "inspect", "flags": { "input": "@build", "check": ["deterministic", "no-symlinks"], "format": "json", "summary": true } }, + { "id": "verify", "command": "verify", "flags": { "input": "@build", "strict": true, "format": "json", "summary": true } }, + { "id": "unpack", "command": "extract", "flags": { "input": "@build", "output-dir": "staging" } } +] } +``` + +`zipnative batch --manifest tasks.json --json` then prints one document on stdout: +`{ ok, command: "batch", mode: "manifest", total, succeeded, failed, skipped, tasks: [{ id, command, ok, output?, report?, stdout?, stdoutBytes?, skipped?, error?: { code, message, zipCode? } }] }` +(the `build` and `unpack` tasks have `stdoutBytes: 0`; their status envelopes went to stderr). + +`"@"` references the resolved output (or output-dir) of an **earlier** task; +relative paths resolve against the manifest's directory and manifest path values get +the `..` refusal that argv paths do not (`E_INPUT` "Path traversal detected"); 10 +manifest commands are whitelisted — `create`, `list`, `inspect`, `extract`, `cat`, +`verify`, `stream`, `modify`, `crc32`, `inflate` (never `batch`, `govern`, `schema`, +`completion`, `doctor`). Validate the file with `schema batch-manifest`, pre-flight +with `--dry-run` (it also enforces the `--json` stdout policy), and remember: a +`codec` flag inside a manifest additionally requires `--allow-codec-load` on the +command line — a manifest obtained from elsewhere can never execute user code on its +own. A manifest has the filesystem access of the user who invokes `batch` — the same +trust level as flags typed on the command line. Manifests are size-capped (50 MB) and +bounded to 1 000 tasks; directory mode's `--concurrency` accepts 1–64. Exit 1 carries +the first failing task's `E_*` code and `zipCode`. + +--- + +## 8. Safety notes for unattended use + +- **Offline, always.** No command opens a socket — not `doctor`, not `govern`, not + `schema`, not `--json`. The engine never touches the network either. There is nothing + to allow-list. +- **Run hermetically.** `--no-config` (or `--config `) in every unattended call — + `.zipnativerc.json` discovery walks up to the filesystem root (§1). +- **The sink is guarded three times.** The engine sanitises every path + (`sanitizeEntryPath`) and refuses hostile shapes; the CLI re-proves lexically that each + destination stays under `--output-dir` (`safeJoin`); then, before creating a directory, + it `realpath`s the nearest existing ancestor and requires it to sit under the root's + `realpath` (a symlink or junction pre-planted inside the destination cannot redirect + `mkdir -p`; the created directory is re-checked). Files are created exclusively (`wx`) + unless `--overwrite`, so a file appearing between the plan and the write is refused + like any other; case-fold collisions are refused on case-insensitive filesystems; a + symlink is never materialised. Opt-outs skip; they never write anything unsafe. A + residual window exists between the `realpath` check and the open — extract into an + empty or trusted directory. +- **Overwrite is opt-in everywhere.** `create -o`, `modify -o`, `cat -o`, + `inflate -o`, `extract`, `stream --output-dir` and `batch --task create` refuse an + existing file (`E_IO`) unless `--overwrite`; `modify --in-place` writes an + unpredictable exclusive temp file and renames atomically. Interrupting (SIGINT / + SIGTERM) removes the in-flight files and exits 130 / 143. +- **Bounded input.** The engine's eight CWE-tagged limits are always on (100000 entries, + 1 GiB per entry, 8 GiB total, 1024:1 ratio, 4096-byte names, 65535-byte extra fields and + comments, 256 MiB central directory) — when reading **and** when writing; tighten them + for untrusted uploads (`--max-total-size 512m --max-ratio 50`). `--max-input-size` + (default 4 GiB) bounds every buffered read of an archive or payload, so a huge upload + cannot exhaust memory before the engine sees it; the streaming commands stay + constant-memory. `none` disables a bound and warns — never do that on untrusted input. + JSON inputs are capped at 50 MB; a captured `batch --json` task stdout at 64 MiB. + `inflate` always has an output bound. +- **Argv paths are yours; data paths are checked.** `--input ../a.zip` or + `-o ../out.zip` is ordinary shell usage and is not second-guessed. Paths that arrive as + *data* — batch-manifest path flags, create/modify-manifest `path` values — are refused + when they contain `..`. Entry **names** are always checked with the engine's + `sanitizeEntryPath()`. +- **`modify` never launders a lying record.** The archive is opened eagerly (overlap / + CD↔LFH structure checked before any edit) and every untouched entry is verified + (CRC-32, sizes, local header — one decompress pass, never a recompress) before it is + re-emitted verbatim; a failure is `E_DATA` / `E_SECURITY` with `entryName`. + Encrypted and stream-only-codec entries are copied as-is and counted in + `verifySkipped`; an unregistered method is `E_UNSUPPORTED`. There is no opt-out. +- **Data remanence.** `modify` without `--compact` keeps removed / replaced bytes + recoverable in the output. When deletion matters, pass `--compact`. The CLI prints an + `info:` line and the engine emits `ZIP_DEAD_BYTES_RATIO` when it is significant. +- **Forward reading is unverified metadata.** `stream` trusts local headers alone — no + central directory to cross-check names, sizes or methods — so mode / symlink policy is + unavailable, data-descriptor entries show zero sizes (`bytesKnown: false`), custom-method + entries cannot be decoded, and every JSON output says `trust: "local-headers-only"`. + Use it only for streams you cannot seek; prefer `list` / `extract` on a complete file. +- **`--codec` runs user code and shapes what you write.** It is the CLI's only dynamic + import (same trust as `node -r`): argv only, refused from `.zipnativerc.json`, refused + inside a `batch --manifest` without `--allow-codec-load`. Codecs are not read-side + only: a module registering method 0/8 replaces the compressor of `create` / `modify` + (announced by a `warning:`, also under `--deterministic`), a `deflateImpl` replaces the + deflate tier (`tier: "injected"`) unless `--deterministic`, and `create --parallel` + refuses either because its worker pool never sees the module. Never pass a module you + did not author or vet. +- **Timestamps are host-independent only when you pin them.** `--date ` and + manifest dates are UTC wall-clock (identical DOS fields on every host); `--date now` + and `--mtime` are local time and not reproducible; `--stream` output is reproducible + but not canonical (`layout: "data-descriptor"`). +- **No encryption.** Encrypted entries are detected, listed and reported as `skipped` + by `verify`; reads fail with `ZIP_UNSUPPORTED_ENCRYPTION`; `extract` / `stream` + `--skip-unsupported` skip them. Do not expect a password flag. +- **Human-in-the-loop for governance.** `govern` never submits anything; it only drafts + and verifies.

flags and positionals are order-independent; `--flag=false|0|no|off` is the + explicit off form (audit A-01). +- `EPIPE` on stdout / stderr (a downstream `| head` closing the pipe) ends the run quietly + with exit 0 instead of an unhandled `'error'` event, a stack trace and exit 1 (audit A-03). +- A read command with no input on an interactive terminal is refused (`E_USAGE`, "No input: + pass --input (or a positional path), or pipe data on stdin.") instead of blocking + forever;

every ISO + date is normalised to its UTC components before the engine encodes it (audit A-02). +- `create --parallel` refuses (exit 2) a `--codec` module registering method 0 / 8, and a + `deflateImpl` without `--deterministic`: the worker pool never sees the module and the + envelope previously reported `tier: "injected"` while the workers compressed with + `node:zlib`; under `--parallel` the tier is `node-zlib` or `pure-pinned`, never `injected` + (audit B-02). +- `cat` falls back to `readEntry()` (one entry buffered) for a `--codec` method that has + `decompressSync` but no `decompressStream` (was `ZIP_UNSUPPORTED_CODEC_MODE`, while + `extract --buffered` could read it) (audit B-17). +- `create --dry-run` / `extract --dry-run` print no text plan when agent mode comes from + `ZIPNATIVE_JSON` (was: the plan on stdout **and** the envelope on stderr) (audit A-12). +- Colours are decided on **stderr** (the only stream that carries them): `NO_COLOR` off, + `FORCE_COLOR` on, `TERM=dumb` off, otherwise on only when stderr is a TTY (audit A-13). +- A forward-read failure before the first header no longer carries an empty `entryName` + (audit B-29). +- Every CLI-side `E_NOT_FOUND` (`cat`, `inspect --entry`, `stream --cat`, `verify --entry`) + carries `zipCode: "ZIP_ENTRY_NOT_FOUND"` and names the remedy (audit B-40). +- `govern policy` deep-equals `.github/ai-governance.json` (`spec_updated`, + `compliance_report.description`, `capability_manifest`, `verification.advisory_in_ci`, + `references` were missing) and every rule line of `govern rules` appears verbatim in + `.github/AGENT_RULES.md` (audit A-10). +- Completions: path flags (`--input`, `--output`, `--output-dir`, `--input-dir`, `--base`, + `--from-manifest`, `--manifest`, `--config`, `--codec`, `--comment-file`) complete files in + bash (`_filedir` / `compgen -f`), zsh (`_files`) and fish (`-r -F`);

The residual realpath → open window is + documented in SECURITY.md ("use an empty or trusted destination") (audit A-06). +- **Exclusive opens** — every file the CLI writes is opened with `wx` unless `--overwrite`, so + a file that appears between the plan and the write is refused like any pre-existing one (no + check-then-write window); `modify --in-place` writes to an unpredictable, exclusively + created temp file `.tmp--<12 hex>` instead of `.tmp-` (audit A-07). +- **`modify` verifies what it re-emits** — eager open (overlap / CD↔LFH structure before any + edit) and `reader.verifyEntry()` on every entry not removed or replaced before `save()` / + `saveCompact()`: `!localHeaderMatch` → `E_SECURITY` `ZIP_CD_LFH_MISMATCH`, `!crcMatch` → + `E_DATA` `ZIP_CRC_MISMATCH`, `!sizeMatch` → `E_DATA` `ZIP_SIZE_MISMATCH`, each with + `entryName`; encrypted and stream-only-codec entries are copied as-is and counted in + `verifySkipped`; an unregistered method is `E_UNSUPPORTED`.

The bridge is + the 77-export coverage ledger mapped in `docs/KNOWLEDGE_BASE.md` §8. +4. **Agent-first.** stdout = artifact, stderr = diagnostics/envelopes, stable + exit codes (0/1/2), 13 stable `E_*` classes and the engine's `ZIP_*` code + carried verbatim as `zipCode`. Every core call is wrapped with + `guard()` / `mapZipError()` from `src/utils/ziperr.ts` — that module is the + only place allowed to read `err.code`. Agent mode is a thin presentation + layer, never a second runtime. +5. **Never loosen a security default.** `rejectTraversal`, `rejectSymlinks`, + `onDuplicate: 'error'`, every `ZipLimits` bound, `--max-input-size`, the + sink containment (`safeJoin` + realpath re-check + exclusive open in + `src/utils/sink.ts`), the uniform overwrite refusal, `modify`'s + verification of every re-emitted entry (no opt-out), the `--codec` + argv-only rule and the manifest `--allow-codec-load` gate stay as they are + unless a human records the decision. Opt-outs skip; they never write + anything unsafe. A symlink is never materialised. +6. **Offline, always.** No command opens a socket, and no change may add one. + There is no network opt-in to extend. +7. **ESM-first TypeScript strict.** Relative imports carry the `.js` + extension. No `console.log` (write to `process.stdout`/`process.stderr`), + no `any`, prefer `const` and `readonly`.

All four shells, `schema manifest`, `doctor`'s command count + and the docs test derive from this table. Every **boolean** flag also goes + into `COMMAND_BOOLEAN_FLAGS` in `src/utils/flags.ts` (otherwise the parser + makes it consume the next token); a path-valued flag goes into + `PATH_FLAGS` so the shells complete files.

Coverage thresholds (enforced by `vitest.config.ts`, the single +source of truth): **statements 93 %, branches 88 %, functions 94 %, lines 93 %** — ratcheted after +the 1.0.0 audit pass from the measured 96.32 / 92.52 / 97.93 / 96.91 (2026-09-05), three points +below the actuals so a legitimate refactor does not flap the gate. Never lower them to make a +change pass — add tests. The suite is 61 files / 1202 tests (9 are platform-conditional and skip +with a stated reason). + +Tests run the command functions **in-process** with `process.stdout` / `process.stderr` captured +(`tests/helpers/capture.ts`); adversarial archives (overlaps, zip-slip, CRC lies, descriptor +tricks, prepended stubs, encrypted survivors, custom methods) are generated in-test by the +engine-independent `tests/helpers/raw-zip-builder.ts` and are **never committed** — the only +committed archives are the two foreign-provenance interop fixtures listed in +`tests/fixtures/README.md` (enforced by `tests/docs/fixture-policy.test.ts`). + +### Pinned docs + +The documentation is part of the test surface — update the docs, not the tests: + +- **`tests/docs/consistency.test.ts`** pins README, `llms.txt`, AGENTS.md, the knowledge base, + SECURITY.md, CITATION.cff and the USAGE strings to the code: the 15-command count in every + document; the 13 `E_*` codes (every token in the docs is real, every code is documented in + AGENTS.md and `llms.txt`); the 77-export map (`docs/data/core-exports.json` ↔ KB §8 ↔ the + bridge); the 39 `ZIP_*` codes and 11 diagnostics (`docs/data/errors.json` ↔ `ZIP_TO_CLI` ↔ + AGENTS.md, plus a `raisedBy` list per diagnostic); the README global-options table (every + `--max-*` flag with its engine default, the `--max-input-size` row with default and CWE, the + `--dry-run` command list); the README schema section (exactly the 22 subjects); the manifest / + projected command lists in AGENTS.md and `llms.txt`; every `--flag` of every command in its + USAGE block, its README section and the knowledge base (booleans never shown with a + ``, no USAGE line over 80 columns, `PATH_FLAGS` ⊆ the value flags); the global USAGE + naming every bound, the exit codes and every `ZIPNATIVE_*` variable read in `src/`; the + `status` schema's `command` enum = the set of `emitStatus()` callers; CITATION.cff `version` = + `package.json`; the retracted "reader-only" codec claim (audit B-07) absent from every + document; every relative path in the `llms.txt` Docs section shipped in the tarball. +- **`tests/utils/governance-sync.test.ts`** pins `govern`: `AI_GOVERNANCE_POLICY` deep-equals + `.github/ai-governance.json`, every numbered rule and every "must NOT" bullet of + `AGENT_RULES_TEXT` appears verbatim in `.github/AGENT_RULES.md`, and every file named in the + capability manifest exists. +- **`tests/docs/fixture-policy.test.ts`** pins `tests/fixtures/README.md` (the provenance + ledger, the 20 KB budget, the generated-only rule). +- **`tests/scripts/verazip-vendor.test.ts`** pins the vendored validator to its upstream commit + and blob hashes, its 22-id check vocabulary and its anti-circularity (never imports + `zipnative`, `src/` or `dist/cli.cjs`). + +Because of these relations, **CI runs on documentation changes too** (see below). + +## Conformance validation (veraZIP) + +ZIP has no reference validator the way PDF/A has veraPDF, so the CLI ships its own gate. +`npm run validate:zip` builds `dist/cli.cjs`, drives the **built** CLI (plus an +engine-independent raw builder for the canaries) to write a **37-archive corpus** to +`test-output/zip/` with a `manifest.json` (`scripts/generate-zip-corpus.mjs`), then validates +every archive against **ISO/IEC 21320-1:2015** (Document Container File — the +ISO-standardised ZIP profile) with `scripts/validate-zip.mjs` and compares each verdict with +the manifest's expectation. The expected verdict is **33 PASS, 4 XFAIL, 0 FAIL**. + +**Independence.** `validate-zip.mjs` is **vendored** from the engine +(`zipnative/scripts/validate-zip.ts`, commit `4f1bc36`; the upstream commit and blob hashes +are recorded in its header, and a vendor test pins them). It raw-parses the bytes with its own +EOCD / central-directory / local-header reader and never imports `zipnative`, `src/` or runs +`dist/cli.cjs` for parsing — a validator that shared the engine's parser would attest the +engine with the engine. When upstream's `validate-zip.ts` changes, re-port the parser body 1:1 +(types erased) and bump both hashes in the same PR. + +**The corpus.** 33 conformant archives (37 = 33 + 4) cover every writer path (buffered, +`--stream`, `--parallel`, `--deterministic`, store / deflate, string and binary comments +(`--comment-file`), `--order insertion` (an EPUB-style `mimetype`-first layout), manifest +`extraFields`, directory entries, `modify` append-only and `--compact`, `--from-manifest`, +`batch`). Three of them are **hostile-but-conformant** (zip-slip, a Windows device name, +duplicate paths): the ISO profile constrains the container's structure, not the meaning of entry +names, so they PASS the validator — and the manifest records that `extract` **must refuse** them +(`refusedBy`), which the gate also checks. Four **raw-crafted negative canaries** +(`expectConformant: false`) must be rejected with their declared check id — +`WF/ENTRY-OVERLAP`, `WF/CD-COUNT`, `WF/LFH-SIZE-MISMATCH`, `WF/LFH-NAME-MISMATCH` (the +well-formedness cross-checks lenient extractors forgive). A coverage canary fails the run if a +manifest file is missing, is not a ZIP, or a required check id has no canary — a corpus +generator that silently dropped a canary would otherwise shrink the gate without anyone +noticing. The generator removes each target before regenerating it (the CLI refuses to overwrite +an existing output otherwise). + +**Levels.** + +- **Level 0** — the ISO/IEC 21320-1 clause checks (no multi-volume, no encryption, no + digital-signature record, version needed ≤ 45, forbidden general-purpose bits, UTF-8 + discipline, methods 0 / 8 only, no volume labels) plus the APPNOTE well-formedness + cross-checks (central directory ↔ local header agreement, offsets, counts, overlaps, + data-descriptor validation). **Needs nothing** — pure byte parsing — and **always runs**. +- **Level 1** — every conformant archive is re-tested with the foreign integrity tools present + on the machine (`scripts/helpers/interop-tools.mjs`, vendored from the engine's + `tests/helpers/interop-tools.ts`): `tar -tf` (bsdtar), `unzip -t`, `7z t`, + `python -m zipfile -t`, `jar tf`. Exit codes are read per each tool's own contract (unzip's + and 7-Zip's documented exit 1 "warnings" count as a pass). Absent tools are reported as + `SKIP integrity ` — never simulated; documented per-file exclusions + (`integrityExclude`) carry known tool limitations instead of loosened exit codes. +- Level 2 (the differential-extraction matrix) stays in zipnative's own interop suite. + +**Outcomes** per manifest file: `PASS` (conformant as expected), `FAIL` (non-conformant +although expected conformant, or a negative that failed with the *wrong* check id), `XFAIL` +(negative canary rejected with its declared id), `XPASS` (a negative canary accepted — the +validator is not validating; always fatal), `INFRA` (parser exception / unreadable file — not a +verdict). Per-file JSON reports and a `summary.json` land in `test-output/zip/reports/`. + +| Exit | Meaning | +|------|---------| +| 0 | Every expectation met — **or** no level-1 tool is usable and `VERAZIP_REQUIRED` is unset: level 1 is **SKIPPED** (exit 0 is a skip of level 1, not a pass of it; level 0 verdicts still hold) | +| 1 | A conformance expectation was not met (`FAIL` / `XPASS`), a level-1 tool rejected a conformant archive, the coverage canary tripped, the corpus has no negative canary, or a required check id has no canary | +| 2 | Corpus directory / manifest absent — run `npm run corpus:zip` first | +| 3 | `INFRA`: a file produced an INFRA outcome, or (`VERAZIP_REQUIRED=1` only) zero level-1 tools are usable | + +Environment: `VERAZIP_REQUIRED=1` fails closed (no usable level-1 tool → exit 3 instead of a +skip; set in CI, unset locally so a bare machine never blocks); `VERAZIP_REPORT_DIR=` +relocates the reports; `VERAZIP_TOOLS=` restricts level 1 to a subset of +`bsdtar,unzip,7z,python-zipfile,jar` (`none` disables it). + +**CI is blocking**: the same scripts run with `VERAZIP_REQUIRED=1` on Linux and Windows on +**every push and pull request** — `.github/workflows/verazip.yml` carries no `paths:` filter, so +it can be a required check without the "Expected — Waiting for status" trap — and again as a +pre-publish gate in `.github/workflows/publish.yml`. No dependency is added — the validator is +a script and the foreign tools are external. + +Installing the level-1 tools locally (**level 0 needs nothing**): + +```bash +# macOS (bsdtar, python3 and jar ship with the OS / Xcode / a JDK; unzip is built in) +brew install p7zip + +# Debian / Ubuntu +sudo apt-get install unzip p7zip-full python3 default-jdk-headless # bsdtar: libarchive-tools +``` + +```powershell +# Windows — tar.exe (bsdtar) is built in since Windows 10; Python from python.org or winget +winget install 7zip.7zip +winget install Python.Python.3.12 +# jar comes with any JDK (e.g. winget install Microsoft.OpenJDK.21); Info-ZIP unzip is optional +``` + +**PR checklist**: if you change anything the CLI **writes** (`create`, `modify`, `batch --task +create`, name handling, the corpus generator) or the validator itself, make sure +`npm run validate:zip` passes locally — and remember that exit 0 without any level-1 tool is a +skip of level 1, not a proof of it.

When you add or change a command: + +- **Wrap every core call** with `guard('context', () => …)` or `mapZipError(e, 'context', + entryName)` from `utils/ziperr.ts` — that module is the only place allowed to read the + engine's `err.code`. An autonomous caller must always receive the stable class + (`error.code`), the exact cause (`error.zipCode`), the entry name and the code-specific + `detail` when the engine knows them. +- Throw `CliError(message, exitCode, ErrorCode.X, { zipCode?, entryName?, detail? })` with a + stable code from `utils/error.ts`. Numeric exit codes (0/1/2) must not change: usage and + malformed flags are `E_USAGE` / exit 2, unsafe or malformed **data** (an entry name, a manifest + value) is `E_INPUT` / exit 1. A new engine code fails `tsc` in `ZIP_TO_CLI` until it is + mapped — map it, regenerate `docs/data/errors.json`, and update the tables in AGENTS.md and + the knowledge base. Every refusal names the next action (a flag or a command to run). +- Pass `commonOptions(args, sink)` (`{ strict, onDiagnostic, limits }`) to every engine entry + point so `--strict`, the diagnostics bridge and the `--max-*` bounds apply uniformly; every + buffered read goes through `readFileOrStdin` / `readArchiveBytes` so `--max-input-size` + applies. +- Keep **stdout** for the artifact and **stderr** for diagnostics. For success status on a + write command, call `emitStatus({ command, …, ...sink.field() })` (no-op outside `--json`); + the `status` schema's `command` enum is tested against the callers. +- Honour `--dry-run` via `hasFlag(args.flags, 'dry-run') || isDryRun()` (agent mode may come + from the environment, so branch on `isJsonMode()`, never on `hasFlag('json')`) and add the + command to `DRY_RUN_COMMANDS` in `commands/completion.ts`. +- Write files through `writeOutput` / `writeFileStream` / the sink (`utils/sink.ts`) so the + uniform overwrite policy (exclusive open unless `--overwrite`), partial-file removal and the + `SIGINT` / `SIGTERM` cleanup (`utils/inflight.ts`) apply. +- Never loosen a security default: opt-outs skip, they never write anything unsafe; a symlink + is never materialised; every destination goes through `safeJoin` and the sink's realpath check. +- **Register every flag** in the `COMMANDS` table (completions, `schema manifest`, `doctor` and + the docs test derive from it). A **boolean** flag must also be listed in `utils/flags.ts` — + the boolean-flag table is what stops the parser from consuming the next token — and a flag + that takes a **path** must be added to `PATH_FLAGS` in `commands/completion.ts` so the shells + complete files after it.

Every archive the CLI writes is validated against +> **ISO/IEC 21320-1:2015** in CI (the veraZIP gate). **Node ≥ 22**. +> See [release notes](release-notes/v1.0.0.md) and [AGENTS.md](AGENTS.md). +> +> ⭐ Star [`zipnative`](https://github.com/Nizoka/zipnative) — the zero-dependency ZIP engine that powers this CLI. + +## Highlights + +- **`create`** — build an archive from files, directories, stdin or a JSON manifest through + zipnative's deterministic writer: canonical entry order, DOS-epoch timestamps and UTF-8 names + by default, **`--deterministic`** to pin the pure-TS encoder (identical SHA-256 on every + runtime), **`--stream`** for a constant-memory writer (streamed inputs, data-descriptor layout), + **`--parallel`** to fan deflate out across a worker pool (`zipnative/worker`), `--include` / + `--exclude` globs, `--order insertion` (argv order — an EPUB `mimetype` first), `--store-ext`, + `--preserve-mode`, archive and per-entry comments (`--comment-file` for raw bytes), and a + `--dry-run` plan. An existing output file is refused without `--overwrite`. +- **`list` / `inspect`** — list entries without decompressing anything (`text` | `json` | + `ndjson`, `--long` for flags, offsets and extra fields), or open the archive **eagerly** for a + forensic report — per-method statistics, a determinism verdict, every engine diagnostic — and + turn it into a CI gate with repeatable **`--check`** assertions (`deterministic`, + `no-encryption`, `no-symlinks`, `max-ratio=N`, `has=`, …; exit 1 / `E_CHECK_FAILED`). +- **`extract`** — secure by default. The engine sanitises every path; the CLI is the filesystem + sink and re-proves containment under `--output-dir` — lexically and physically (`realpath`) + — before writing a byte, and opens every file exclusively. Zip-slip, Windows device names, + symlink entries, overlapping entries, central-directory / local-header disagreement, + duplicate output paths and decompression bombs are **refused**, each with its `ZIP_*` code. + Opt-outs are skip-not-write (`--skip-unsafe`, `--skip-symlinks`, `--skip-unsupported`; + `--allow-symlinks` writes the link *target text* as a plain file — a symlink is never + materialised). Existing files are never overwritten without `--overwrite`. +- **`cat`** — stream one or more entries to stdout (or `--output`) by random access: a single + file from a multi-gigabyte archive never materialises the rest. `--raw` emits the compressed + payload zero-copy. +- **`stream`** — a forward-only reader for **unseekable** input (stdin, a pipe, an upload body): + list, extract or `--cat` entries as they arrive, with the engine's trust caveat made explicit + (`trust: "local-headers-only"` in every JSON output — there is no central directory to + cross-check). +- **`verify`** — one-call deep integrity verification via zipnative's `verifyZip`: eager + structural validation, per-entry CRC-32 / size / local-header agreement, diagnostics collected. + The report is always the artefact; the exit code is the verdict (`E_VERIFY_FAILED`, with + `zipCode` set for structural refusals). Encrypted entries are honestly reported as *skipped*, + never faked as verified. `--strict` also fails on any diagnostic. +- **`modify`** — add, replace, remove, rename entries or set the comment **without + recompressing untouched entries**. Every untouched entry is **verified** (CRC-32, sizes, + local header) before it is re-emitted verbatim — a lying record is refused, never laundered. + The default save is append-only (original bytes verbatim); **`--compact`** rewrites + canonically so removed content is truly gone. `--in-place` writes back through an + exclusively created temp file + atomic rename. +- **`crc32` / `inflate`** — the ZIP checksum of files or stdin in constant memory (`--expect` + turns it into a check, `--seed` continues a running value), and a raw-DEFLATE decoder with a + **mandatory output bound** driven by zipnative's resumable inflater (`--method ` for + codecs loaded with `--codec`). +- **`batch`** — archive every subdirectory of a folder (the full `create` command per + directory, bounded concurrency), verify every `*.zip` in a folder, or run a declarative + **`--manifest`** pipeline (`create` → `verify` → `extract` → …) with `@` output references + and a codec-load policy (`--allow-codec-load`). Under `--json` stdout is **one** batch + document with every task's captured report inside. +- **`doctor`** — an offline capability preflight: CLI / Node / zipnative versions (package vs + the engine's `VERSION` export), the active deflate tier (`node-zlib` expected, `pure` under + `--pure-codecs`), the pinned tier used by `--deterministic`, platform streaming codecs, + worker-thread availability for `create --parallel`, registered codecs, the **effective + security limits** (as numbers under `data`, `--max-input-size` included), and the command + count. Text or `--format json`; exit 0/1. +- **`schema`** — 22 versioned subjects: JSON Schemas (Draft 2020-12) for every input and output shape, the `errors` registry + plus the machine-readable **capability manifest** (`schema manifest`) and + [`llms.txt`](llms.txt), so agents can self-validate and discover the tool at runtime. +- **`completion`** — `bash`, `zsh`, `fish` or `powershell` completion scripts, generated from the + same command table that feeds the manifest. +- **`govern`** — zipnative's AI-governance / Human-in-the-Loop contract: `govern rules`, + `govern policy`, and `govern verify-issue ` to gate an issue/PR draft (exit 1 / + `E_POLICY`) before a **human** reviews and submits it. +- **Agent-native** — a global `--json` status/error envelope, 13 stable `E_*` classes, the exact + `ZIP_*` cause carried verbatim as `error.zipCode` (39 frozen codes, plus 11 diagnostic codes), + `--dry-run` on seven commands, `--strict`, and token-economy levers (**`--summary`**, + **`--fields a,b.c`**, compact JSON under `--json`). See [AGENTS.md](AGENTS.md). +- **Bounded by default** — the engine's eight CWE-tagged `ZipLimits` are exposed as + `--max-entries`, `--max-entry-size`, `--max-total-size`, `--max-ratio`, `--max-name-bytes`, + `--max-extra-bytes`, `--max-comment-bytes` and `--max-cd-bytes`; the CLI adds + `--max-input-size` (4 GiB) on every buffered read (`none` disables a bound, with a visible + warning). +- **`.zipnativerc.json`** — optional config file for default flags (global + per-command); + precedence is CLI flags > config > built-in. `codec` is refused from config files. +- **Zero extra dependencies** — `zipnative` is the sole runtime dependency; all ZIP logic lives + there. No ZIP parsing in the CLI. +- **Offline, always** — no command can open a socket. There is no network opt-in to forget. +- **Stdin / stdout by default** — every command is shell-pipeline friendly. +- **TypeScript strict, ESM source** — bundled by tsup into one CommonJS bin (`dist/cli.cjs`). + The package is a command-line tool only: no programmatic entry point, no type declarations. +- **npm provenance** — Trusted Publishing (OIDC) with provenance attestations and a CycloneDX + SBOM per release. + +## Supported Features + +| Feature | Status | Notes | +|---------|--------|-------| +| **Commands** | | | +| `create` deterministic archives | ✅ | Files, directories, stdin, `--from-manifest`; `--method`, `--level`, `--deterministic`, `--order canonical\|insertion`, `--date` (UTC), `--stream`, `--parallel`, `--include`/`--exclude`, `--store-ext`, `--preserve-mode`, `--dir-entries`, `--comment` / `--comment-file`, `--overwrite` | +| `modify` incremental edits | ✅ | `--add`, `--add-dir`, `--replace`, `--remove`, `--rename`, `--comment` / `--comment-file`, `--from-manifest`; every untouched entry verified before re-emission; append-only `save()` or `--compact`; `--in-place`, `--overwrite` | +| `list` entries | ✅ | `text` \| `json` \| `ndjson`, `--long` (with `rawNameHex` / `commentHex`), `--validate eager`, globs, `--summary` / `--fields` | +| `inspect` forensic report | ✅ | Eager open, stats, determinism verdict (`deterministic` = reproducibility, `canonicalLayout` = form), diagnostics, `--entries` / `--entry` / `--extra`, 20 `--check` assertions | +| `cat` entries to stdout | ✅ | Random access, `--raw` (compressed payload), `--no-verify-crc`, `--output` (+ `--overwrite`) | +| `extract` to a directory | ✅ | Guards on by default; `--skip-unsafe`, `--skip-unsupported`, `--allow-symlinks`, `--skip-symlinks`, `--on-duplicate`, `--overwrite`, `--flat`, `--buffered`, `--preserve-mode`, `--preserve-mtime` | +| `stream` forward-only reader | ✅ | stdin/pipes; `--list` (default), `--output-dir`, `--cat`; `trust: "local-headers-only"`; `--skip-unsafe`, `--skip-unsupported` | +| `verify` deep integrity | ✅ | `verifyZip` report + `failed` / `skipped` / `strict`; `--entry` verifies selected entries; exit 1 / `E_VERIFY_FAILED` | +| `crc32` checksum | ✅ | Files or stdin, 64 KiB chunks; `--seed`, `--expect` (exit 1 / `E_CHECK_FAILED`) | +| `inflate` raw DEFLATE | ✅ | Resumable inflater, mandatory `--max-output`, `--sync`, `--method ` for registered codecs; envelope reports `bytesConsumed` / `leftover`; `--overwrite` | +| `batch` orchestration | ✅ | Directory mode (`--task create` \| `verify`, `--concurrency` 1–64, `--fail-fast`, `--overwrite`) or `--manifest` pipelines (10 whitelisted manifest commands); one JSON document on stdout under `--json` | +| `doctor` preflight | ✅ | Versions, deflate tiers, web streams, workers, codecs, effective limits (numbers under `data`), command count; text or `--json` | +| `schema` JSON Schema export | ✅ | 22 subjects incl. `errors`, `limits`, `diagnostics`, `status`, `error` and the capability `manifest` | +| `completion` shell scripts | ✅ | `bash` / `zsh` / `fish` / `powershell` | +| `govern` AI-governance / HITL | ✅ | `rules` / `policy` / `verify-issue`; gates drafts with `E_POLICY` | +| `.zipnativerc.json` config file | ✅ | Global + per-command defaults; flags > config; `codec` refused from config | +| **Agent & automation** | | | +| Global `--json` envelope | ✅ | Status on success, `{ ok: false, command, error: { code, message, zipCode?, entryName?, detail?, remedy?

Three of the conformant archives are +**hostile-but-conformant** (zip-slip, a Windows device name, duplicate paths): the ISO profile +constrains the container, not the meaning of names, so they PASS the validator and `extract` +**must refuse** them — the gate checks both (`33 PASS, 4 XFAIL, 0 FAIL`). Level 0 (the ISO clauses) +needs no external tool and always runs; level 1 re-tests every conformant archive with the +foreign integrity tools present on the machine (`unzip -t`, `7z t`, `python -m zipfile -t`, +`tar -tf`, `jar tf`) and **skips** the absent ones visibly; `VERAZIP_REQUIRED=1` (set in CI) +fails closed.

One extraction sink serves `extract` and `stream`: lexical + containment of every destination under `--output-dir` (`safeJoin`), **physical** containment + (the nearest existing ancestor is `realpath`-checked under the root's `realpath` before any + `mkdir`, and re-checked after — a planted symlink or junction is `E_SECURITY`), an + **exclusive** open (`wx`) unless `--overwrite`, removal of partial files on failure, and + case-fold collision refusal on case-insensitive filesystems. The only residual window is + between `realpath` and `open` — use an empty or trusted destination. A symlink is never + materialised, whatever the flags. +- **Overwrite refusal is uniform.** `create` / `modify` / `cat` / `inflate --output`, `extract`, + `stream --output-dir` and `batch` refuse an existing file (`E_IO`) unless `--overwrite`; + `modify --in-place` goes through an exclusively created, unpredictable temp file and an + atomic rename. An interrupted run (`SIGINT` / `SIGTERM`) removes only the files being written + at that moment and exits 130 / 143. +- **Refusals, not guesses** — zip-slip and device names, symlink entries, overlapping entries, + central/local header disagreement, Zip64 spoofing, duplicate output paths, ambiguous EOCDs and + > 2^53 sizes are refused by default with their `ZIP_*` code. Opt-outs skip; they never write + anything unsafe. +- **Bounded by default** — the engine's eight CWE-tagged limits are always on (`--max-*` to + tune; `none` warns), and the CLI bounds every buffered read with `--max-input-size` (4 GiB; + `E_LIMIT`). `inflate` has a mandatory output bound. +- **Data remanence** — `modify` without `--compact` keeps removed / replaced bytes recoverable + in the output. Use `--compact` when deletion matters. Either way `modify` verifies every entry + it re-emits (CRC-32, sizes, local header) and refuses a lying record — an append-only save + never launders a hostile archive into a clean-looking one. +- **No encryption** — read or write, by engine policy in 1.x. Encrypted entries are detected, + listed and reported as `skipped` by `verify`; reads fail with `ZIP_UNSUPPORTED_ENCRYPTION`. +- **`--codec` is a trust boundary** — the CLI's only dynamic import of user code (same trust as + `node -r`): argv only, refused from `.zipnativerc.json`, refused inside a `batch --manifest` + without `--allow-codec-load`. A module that registers method 0/8 or exports `deflateImpl` + also shapes what `create`/`modify` write — the envelope's `tier` and a `warning:` line say so, + and `create --parallel` refuses to run with such a module loaded. +- **Path validation is scoped to data.** Paths typed on the command line (`../a.zip`, + `-o ../out.zip`) are the invoking user's own filesystem authority and are not second-guessed. + Values that arrive as data — path flags inside a `batch` manifest and `path` values inside a + `create` / `modify` manifest — are refused on `..` (`E_INPUT`); entry names are always checked + with the engine's `sanitizeEntryPath()`, and every extracted destination goes through the sink + above. +- **JSON size cap** — manifests, drafts and JSON inputs are capped at 50 MB before parsing + (config files at 1 MB). +- Signed builds with npm provenance (Trusted Publishing / OIDC) and a CycloneDX SBOM per + release; the SBOM and the tarball are attested with `actions/attest-build-provenance` — verify with + `npm audit signatures`.

`--deterministic`, + `--stream` (data-descriptor layout, reported as `layout` in the envelope), `--parallel` via + `createParallelZip` (`zipnative/worker`), `--method`, `--level`, `--order canonical|insertion` + (insertion = the argv order, so an EPUB `mimetype` listed first is written first), `--date` + (UTC wall-clock, time-zone independent), `--comment` / `--comment-file` (binary comments), + globs, `--store-ext`, `--preserve-mode`, `--overwrite`, `--dry-run`; manifest `extraFields` + and `commentBase64`; names pre-checked with `sanitizeEntryPath`. +- [x] **`modify` command** — `createZipModifier` (`addEntry`, `replaceEntry`, `removeEntry`, + `renameEntry`, `setComment`, `save`, `saveCompact`); eager open and `verifyEntry()` on every + entry it re-emits (CRC / sizes / local header, no opt-out); append-only by default, + `--compact`, `--in-place` (unpredictable exclusive temp file + rename), `--overwrite`, + `--comment-file`, `--from-manifest` (`mode`, `extraFields`, `commentBase64`);

stats, a determinism verdict that + separates reproducibility (`deterministic`) from form (`canonicalLayout`), diagnostics, + `--entries` / `--entry` / `--extra`, 19 `--check` assertions → `E_CHECK_FAILED`. +- [x] **`cat` command** — `readEntryStream` / `readEntryRaw` to stdout or `--output` + (`--overwrite`); falls back to `readEntry` for a sync-only `--codec` method. +- [x] **`extract` command** — `extractZipStream` / `extractZip` with the engine's guards on by + default and the CLI as the proven sink (`src/utils/sink.ts`: `safeJoin` containment, realpath + re-check against planted links, exclusive open unless `--overwrite`, case-fold check); + skip-not-write opt-outs incl. `--skip-unsupported`; `getUnixMode` / `isSymlinkEntry` for + `--preserve-mode` and symlink policy. +- [x] **`stream` command** — `iterateZipEntries` over stdin / pipes (list, extract, cat) through + the same sink, with the trust caveat explicit (`trust: "local-headers-only"`, + `descriptorEntries` / `bytesKnown` in `--summary`). +- [x] **`verify` command** — `verifyZip` report + CLI counters, `--entry` (per-entry + `verifyEntry`), `--strict`, `E_VERIFY_FAILED` with `zipCode`. +- [x] **`crc32` command** — the engine's incremental `crc32()`, `--seed`, `--expect`. +- [x] **`inflate` command** — `createInflator` (resumable, bounded) or `getCodec().decompressSync` + (`--sync`, `--method `), mandatory `--max-output`, `bytesConsumed` in the envelope, + `--overwrite`. +- [x] **`batch` command** — directory mode (create / verify, `--concurrency` 1–64, `--overwrite`) + and `--manifest` pipelines (10 whitelisted manifest commands, `@` references, + `--allow-codec-load` policy); under `--json` stdout is one batch document with every task's + report captured. +- [x] **`doctor` command** — versions (`VERSION` export cross-check), `activeDeflateTier` + (default and pinned), web streams, workers, `getCodec` registry, effective + `DEFAULT_ZIP_LIMITS` + overrides as numbers (`limits.data`, incl. `maxInputSize`), command count. +- [x] **`schema` command** — 22 subjects incl. `errors`, `limits`, `diagnostics`, `status`, + `error` and the capability `manifest`; **`completion`** for four shells (path flags complete + files); **`govern`** (rules / policy / verify-issue, pinned to the `.github` files by a test). +- [x] **Global options** — `--json`, `--pretty`, `--dry-run` (7 commands), `--strict`, + `--quiet`, `--no-color`, `--config` / `--no-config` (`.zipnativerc.json`), the eight + `--max-*` bounds over `ZipLimits` plus the CLI-owned `--max-input-size` (4 GiB default), + `--pure-codecs`, `--codec` (`registerCodec`, `setInflateImpl`, `setDeflateImpl`, reported + truthfully when it shapes the writer), `--format, -f` on every command that has a format. +- [x] **Global flags before the command name** — `zipnative --json list a.zip` and + `list --long a.zip` both work: `src/utils/flags.ts` is the boolean-flag table, so a boolean + never consumes the next token and flags and positionals are order-independent (audit A-01) +- **Type-aware lint and `noUncheckedIndexedAccess`** — ESLint runs `strictTypeChecked` over `src/` (three relaxations, each justified in `eslint.config.js`; tests keep the non-type-checked strict set) and `tsconfig.json` enables `noUncheckedIndexedAccess`. (audit A-44, phase 3). +- [x] **Relative parent paths on argv** — `zipnative list ../a.zip`, `-o ../out.zip` and + `--output-dir ../x` are ordinary shell usage and are accepted: argv paths are the user's own + filesystem authority; the `..` refusal (`validatePath`, `E_INPUT`) now applies only to path + values that arrive as data (manifests), and entry names always go through + `sanitizeEntryPath()` (audit A-09, recorded as a posture change in SECURITY.md → Input + Validation). +- [x] **`--overwrite` for single-file writers** — `create` / `modify` / `cat` / `inflate --output` + and `batch --task create` refuse an existing file unless `--overwrite`, exactly like the + extraction sink; `modify --in-place` writes an exclusive temp file and renames (audit A-14). +- [x] **Process contract** — exit 2 / `E_USAGE` for unknown commands and flags without a command; + a terminal with nothing piped is refused instead of blocking; a closed downstream pipe + (`EPIPE`) ends the run quietly with exit 0; `SIGINT` / `SIGTERM` remove only the in-flight + output and exit 130 / 143; `ZIPNATIVE_*`, `NO_COLOR`, `FORCE_COLOR`, `TERM=dumb` honoured + from the environment. +- [x] **Agent contract** — 13 stable `E_*` classes + the 39 `ZIP_*` causes verbatim + (`ZIP_TO_CLI`, typed against `ZipErrorCode`), `entryName` / `detail`, the diagnostics bridge + (11 codes), token economy (`--summary`, `--fields`, compact JSON), `llms.txt`, + `docs/data/core-exports.json`, `docs/data/errors.json`, `AGENTS.md` — `AGENTS.md`, `llms.txt` + and `docs/data/errors.json` ship in the npm tarball. +- [x] **Blocking veraZIP gate** — `npm run validate:zip` over a 37-archive corpus written by the + built CLI (33 conformant incl. 3 hostile-but-conformant that `extract` must refuse, + 4 + raw-crafted negative canaries → 33 PASS, 4 XFAIL), validated by the ISO/IEC 21320-1:2015 + parser vendored from the engine (independent by construction), level 1 foreign integrity + tools, blocking in `verazip.yml` (Linux + Windows, on every push and PR) and pre-publish. +- [x] **Governance & supply chain** — CI on Ubuntu 22 / 24, Windows 22 / 24 (blocking) and + macOS 22, veraZIP on Linux + Windows on every PR, documentation changes run the suite + (the docs are pinned by tests), CodeQL, Scorecard, Dependabot, Trusted Publishing with + provenance, an attested CycloneDX SBOM and a verified bin-only tarball (7 files), coverage + thresholds 93 / 88 / 94 / 93, AI-governance / HITL files mirrored by `govern`, `CLAUDE.md`. +- [x] **Samples** — 41 dual-shell demos (`.sh` + `.ps1`) across the commands, `samples/agent/`, + `samples/run-all.js` (73 jobs, offline). + +## Future Considerations + +Feasibility is called out honestly: some ideas need zipnative to expose a primitive first (the +CLI stays a thin dispatch layer and never re-implements engine logic). + +- **`zipnative-mcp`** — a Model Context Protocol server exposing the same capabilities to AI + clients, in its own repository pinning `zipnative ^1.0.0` (the ecosystem pattern); the CLI's + `schema manifest` and `docs/data/errors.json` are its contract inputs. Planned upstream. +- **Read-only AES decryption** (`extract --password`, `cat --password`) — **Blocked**: the engine + ships no encryption in 1.x by policy — see the engine's + [What zipnative will NOT do](https://github.com/Nizoka/zipnative#what-zipnative-will-not-do) + (ZipCrypto is broken and will never be written; AES AE-2 may come in a later major behind an + injected crypto provider). The CLI can only surface it once a core crypto-provider seam + exists; it will never implement decryption itself. +- **Streamed entries > 4 GiB** (`create --stream` / `--stdin-name` beyond 4 GiB) — **Blocked** + on the core's per-entry `zip64` opt-in for `addStream` (designed in zipnative's 0.9 ADR, + post-1.0). Today the engine refuses with `ZIP_UNSUPPORTED_ZIP64_STREAMING`; buffered entries + are fully Zip64. +- **Custom-method entries in `stream`** — the engine's forward pump decodes store and deflate + only, so `stream --cat` / `--output-dir` on a `--codec` method fails with `E_DATA` after the + header (listing and skipping work). Waits on the engine using `codec.decompressStream` or + refusing before the first byte (engine issue, human-filed); until then use `cat` / + `extract --codec` on the complete file. +- **`--explain `** — print `raisedWhen` / `remedy` / class / CLI mapping for one + error or diagnostic code from `docs/data/errors.json`, so an agent can resolve a `zipCode` + without leaving the terminal — fed by the same `ZIP_REMEDY` table that already emits + `error.remedy` in the envelope. Feasible now (pure data). +- **`deflate` command** — the twin of `inflate`: raw DEFLATE of a file or stdin through the + engine's deflate facade with the same tier / determinism vocabulary (`--level`, + `--deterministic`). Feasible now. +- **`inspect --diff `** — compare two archives by entry inventory, CRCs, sizes and + determinism facts with CI-friendly exit codes (no content diff). Feasible now, read-only. +- **`create --from-list `** — one path per line (or NUL-separated) as an input list for + very large trees, complementing `--from-manifest`. Feasible now. +- **`--store-symlinks`** on `create` — write symlink entries (Unix mode `S_IFLNK`, target text + as payload) for callers that need them; kept out of 1.0 deliberately because extraction + refuses symlink entries by default and the CLI never materialises one — needs a documented + posture on both sides first. +- **Manifest `externalAttributes` (raw u32)** — folded into the `--store-symlinks` decision above: a raw external-attribute word would let a manifest write `S_IFLNK` entries and bypass the deliberate symlink deferral, so it waits for the same documented posture; `mode` (0o7777 permission bits) remains the supported field on both manifests. (audit B-21) +- **`list --extra` / `stream --extra`** — extra-field hex under `--long` for parity with `inspect --extra` (today ids, names and lengths only). (audit B-39) +- **Inflate-tier visibility in `doctor`** — needs an engine getter (the 1.0 surface exposes `setInflateImpl` but no `activeInflateTier`); until then `doctor` can only say whether a `--codec` module injected `inflateImpl`, and the paths that bypass it (`createInflator`, the forward pump) stay documented in KB §8. (audit B-42) +- **User-level config** — `$XDG_CONFIG_HOME/zipnative/config.json` (or `~/.zipnativerc.json`) as the last fallback after the upward `.zipnativerc.json` discovery; today only the nearest project file is consulted. (audit A-39) +- **Positional arguments in manifest tasks** — `batch --manifest` tasks carry only a flat flag + map today; every whitelisted command accepts its inputs as flags (`input`, `entry`, …), so no + command is excluded, but a `positionals` array would make manifests read like the shell. +- **Engine API asks (human-filed upstream, HITL)** — four compensations the CLI carries until the engine changes: the node-zlib inflate tier should raise `ZIP_DEFLATE_CORRUPT` / `ZIP_DEFLATE_TRUNCATED` like the pure tier (the CLI maps raw zlib codes in `ziperr.ts`); `verifyEntry()` should report the `skipped` reason `verifyZip()` already knows (the CLI re-derives it in `verify --entry` and `modify`); DOS time should not be encoded from local getters (the CLI passes UTC wall-clock components); the forward pump should refuse a custom-method entry before the first byte. Two further asks, no compensation needed: an `analyzeDeterminism()` getter and a write-side `unixMode` helper, the remaining places where the CLI projects what the engine could expose. Drafts live in `.github/drafts/` (git-ignored, see its README). +- **Lazy engine require** — `dist/cli.cjs` requires `zipnative` at bundle top level (≈10 ms of the ≈40 ms `--version` start-up over bare Node); moving the require into the first core call (tsup `splitting` or a lazy getter in the bridge) would make `--help` / `--version` / `schema` engine-free. Measured, not yet worth the bundling risk. (audit A-11) +- **Fuzz / property tests for the CLI-owned parsers** — a seeded generator (or `fast-check` as a devDependency) over `parseArgs`, `compileGlob`, `parseByteSize` / `parseCount`, `parseManifest` and `selectFields`, run in CI; today the suites are example-based only. (audit A-25) +- **One ecosystem governance schema** — the engine's `.github/ai-governance.json` (`version: 1`, `issue_drafting`, `compliance_report_fields`) and the CLI's (`1.0.0`, `policy`, `compliance_report`) differ in shape; agreeing one schema upstream and generating the CLI constant from it is an ecosystem decision, not a CLI change. (audit A-36) +- **man pages** — generated from the USAGE strings; deferred (ongoing maintenance cost vs + `--help` / completions already covering usage). +- **`scripts/verify-docs.mjs`** — port the engine's docs-verification rules (API-JSON sync, + error parity, count consistency) as a script; today `tests/docs/consistency.test.ts` covers + the counts, mappings and flag tables inside the test suite. +- **veraZIP sync automation** — a check that fails when `zipnative/scripts/validate-zip.ts` + changes upstream without the vendored copy (and its recorded commit / blob hashes) being + re-ported. diff --git a/SECURITY.md b/SECURITY.md new file mode 100644 index 0000000..6f56afa --- /dev/null +++ b/SECURITY.md @@ -0,0 +1,137 @@ +# Security Policy + +## Reporting a Vulnerability + +**Please do NOT open a public issue for security vulnerabilities.** + +To report a security vulnerability, please use [GitHub's private vulnerability reporting](https://github.com/Nizoka/zipnative-cli/security/advisories/new) — this is the channel today. + +As a fallback, `security@pdfnative.dev` is the shared maintainer inbox of the pdfnative and zipnative ecosystems.

It introduces zero additional runtime dependencies and **contains no ZIP parsing logic of its own**: every byte of ZIP structure — end-of-central-directory records, central directory, local headers, Zip64, DEFLATE, CRC-32 — is parsed, validated and bounded inside `zipnative`. See the [zipnative security policy](https://github.com/Nizoka/zipnative/blob/main/SECURITY.md) for the engine's threat model and its frozen compatibility promise. + +The engine, by design, never touches the filesystem, never opens a socket and never evals. That makes **the CLI the filesystem trust boundary**: it reads the archive bytes, hands them to the engine, and is the sink that writes extracted data to disk. The invariants the CLI adds on top of the engine are described below. + +The CLI exposes 15 commands (run `zipnative --help` or `zipnative schema manifest` for the authoritative list). **No command can open a socket, in any mode** — there is no network opt-in. + +### Agent Mode (`--json`, `--dry-run`, `--strict`) + +The agent-native contract is a **pure local presentation/validation layer** and adds **no network surface**: + +- `--json` only changes how diagnostics are formatted on **stderr** (a machine-readable envelope). It never alters what is written to stdout and never relaxes any security check. Under `batch --manifest --json` every task's stdout is captured into the single batch document (64 MiB cap → `E_LIMIT`), and a task that would write an artefact to stdout is refused at validation. +- `--dry-run` validates inputs and plans — archives are opened, every destination is proven safe, edits are applied to the modifier, `modify` verifies the entries it would re-emit, manifests are resolved — and short-circuits **before** producing or writing output. +- `--strict` only tightens: the first engine diagnostic becomes a hard error before any output byte. +- Stable `E_*` classes carry a failure class; `error.zipCode` carries the engine's frozen `ZIP_*` cause verbatim; `detail` carries only the structured fields the engine (or the CLI-owned `--max-input-size` bound) defines (`{ limit, configured, observed }`, `{ feature }`, `{ expectedCrc, actualCrc }`). Internal parser state and byte offsets are never exposed beyond what the engine's own remedy-bearing message states. +- The same switches are honoured from the environment (`ZIPNATIVE_JSON`, `ZIPNATIVE_DRY_RUN`, `ZIPNATIVE_QUIET`, `ZIPNATIVE_STRICT`, `ZIPNATIVE_PURE_CODECS`), so a manifest task inherits the mode of its `batch` invocation; there is no environment variable that loosens a check. + +### Extraction sink + +The engine's `extractZip` / `extractZipStream` yield `{ path, entry, data | stream() }` with `path` already run through `sanitizeEntryPath()` and the hostile shapes already refused (`rejectTraversal`, `rejectSymlinks`, `onDuplicate: 'error'`, the limits). `extract` and `stream --output-dir` share **one sink** (`src/utils/sink.ts`), hardened in two phases: + +1. **Plan (lexical)** — the extraction generator is drained **without decompressing anything**. For every entry the CLI recomputes the destination with `safeJoin(root, path)` (`src/utils/io.ts`), which resolves the absolute target and proves it stays inside the resolved `--output-dir` (a relative-path escape, an absolute result or a `..` segment throws `E_SECURITY`). Existing files are refused unless `--overwrite` (`E_IO`). On case-insensitive filesystems (win32, darwin) two entries whose targets fold to the same path are refused (`ZIP_EXTRACT_DUPLICATE_PATH`) unless `--on-duplicate first|last` resolves it deliberately. Directory entries go through `sanitizeEntryPath()` + `safeJoin` too. +2. **Write (physical)** — before `mkdir -p` of a target's parent, the nearest **existing** ancestor is `realpath`'d and must lie under the root's `realpath`; after the directory is created it is re-checked the same way. A symbolic link or junction planted inside the destination that points outside is refused with `E_SECURITY` ("Refusing to write through a link that leaves the output directory…") and nothing is created beyond the link. Every file is then opened **exclusively** (`wx`) unless `--overwrite`, so a file that appears between the plan and the write is refused like any pre-existing one — there is no check-then-write window. Each entry streams into its file with backpressure; a CRC / size failure removes the partial file. `--preserve-mode` applies `mode & 0o777` to files only (never setuid, setgid or sticky; POSIX only). + +**Residual window.** The only gap left is between the `realpath` check and the exclusive `open`: an attacker who can replace a directory with a link *inside that interval* and who already has write access to the destination could redirect one file. The posture is therefore: **extract into an empty or trusted destination**; the CLI never extracts into a location it did not check, but it cannot lock a directory it does not own. + +Opt-outs are **skip-not-write**: `--skip-unsafe` skips entries whose names cannot be made safe (they are listed in the envelope as `skipped: unsafe-path` and never written); `--skip-symlinks` drops symlink entries; `--allow-symlinks` writes the link **target text** as a regular file — **a symlink is never materialised by the CLI under any flag**; `--skip-unsupported` skips encrypted entries and methods with no registered codec (`skipped: unsupported`). `--flat` writes basenames only and applies the same duplicate policy. + +`stream --output-dir` is the same sink over the forward reader: because `iterateZipEntries` does not sanitise names, the CLI applies `sanitizeEntryPath()` itself before `safeJoin`, entry by entry. + +### Overwrite policy + +The policy is **uniform** across every writer, not only the sink: `create -o`, `modify -o`, `cat -o`, `inflate -o`, `extract`, `stream --output-dir` and `batch --task create` (directory mode) refuse an existing file with `E_IO` ("Refusing to overwrite existing file (pass --overwrite)") and leave it intact; `--overwrite` replaces it. `modify --in-place` never writes into the original: it writes to an unpredictable, exclusively created temporary file (`.tmp--<12 hex>`) and renames atomically. Writing to stdout (`-` or no `-o`) is unaffected. Partial outputs are removed on failure, and a `SIGINT` / `SIGTERM` handler removes **only the file currently being written** (never a completed output, never the original of `--in-place`) before exiting 130 / 143. + +### Input Validation + +- **Argv paths are the user's own filesystem authority.** `zipnative list ../a.zip`, `-o ../out.zip` or `--output-dir ../x` are ordinary shell usage and are accepted; the CLI does not second-guess where the invoking user may read or write. `validatePath()` — the `..` refusal, `E_INPUT` "Path traversal detected" — applies to paths that arrive as **data**: the path flags of `batch --manifest` tasks and the `path` values of `create` / `modify` manifests. Entry **names** are a different matter (see below). +- **`--max-input-size `** (global; default **4 GiB**; `none` disables it with a one-shot warning) bounds every **buffered** read: stdin is byte-counted and the read aborted, files are `stat`'d before reading — `list`, `inspect`, `verify`, `extract`, `cat`, `modify`, `create --stdin-name`, `inflate --sync`, `govern verify-issue`. Exceeding it is `E_LIMIT` with `detail { limit: "maxInputSize", configured, observed }` (CWE-400). It is a CLI-owned bound, not a `ZipLimits` key; `doctor` reports it under `limits`. The streaming paths — `stream`, `crc32`, `inflate` (default), `create --stream` — are constant-memory and are not bounded by it. Random-access commands hold the whole archive in memory, so the bound is also the memory envelope. +- JSON input size is capped at **50 MB** before `JSON.parse` — `create --from-manifest`, `modify --from-manifest`, `batch --manifest`, `govern verify-issue` drafts. Batch manifests are additionally bounded to **1 000 tasks**. `.zipnativerc.json` is capped at 1 MB. +- **Manifest values** — `batch --manifest` is validated strictly before anything executes: structural violations exit 2 / `E_USAGE`, value violations (bad or duplicate id, non-whitelisted command, forward or unknown `@ref`) exit 1 / `E_INPUT`; only 10 archive commands may appear (never `batch`, `govern`, `schema`, `completion`, `doctor`); a `codec` flag is refused unless the `batch` invocation itself carries `--allow-codec-load`. A manifest has the filesystem access of the user who invokes `batch` — the same trust level as flags typed on the command line, no more. +- **`--max-*` semantics** — the eight flags map one-to-one onto the engine's `ZipLimits` and are pre-validated (`E_USAGE` on malformed or zero values), so an invalid limits object can never reach the engine. `none` disables a bound (`Infinity`) and prints a one-shot warning; the defaults are always on when no flag is given. `inflate` derives its mandatory `--max-output` default from the effective `--max-entry-size`. The bounds also apply on the write side (`create` / `modify`). +- Every entry name the CLI **writes** (`create` inputs, `--stdin-name`, manifests, `modify --add` / `--rename` / `--add-dir`) is pre-checked with the engine's `sanitizeEntryPath()`: a name that could not be extracted safely is refused at creation time (`E_INPUT`, with `entryName`). Malformed flags stay `E_USAGE`; unsafe **data** is `E_INPUT`. +- Dates are data too: `--date ` and manifest `date` values are read as **UTC wall-clock**, so the stored DOS fields — and the archive bytes — do not depend on the host time zone. +- `list` / `inspect` JSON output is derived from the engine's typed entry objects; raw payload bytes are never emitted except by `cat` / `stream --cat` / `inflate`, whose purpose is exactly that. Raw name and comment bytes are exposed only as hex (`rawNameHex`, `commentHex` under `--long`; `archive.commentHex`) and extra-field payloads only as hex under `inspect --extra`. + +### The engine's guards + +Every row below is enforced by zipnative on every code path the CLI uses; the last column is the CLI switch, if any. + +| Threat | Defence | CWE | `zipCode` | CLI switch | +|---|---|---|---|---| +| Zip-slip path traversal (`../`, absolute paths, drive letters, UNC, backslashes, NUL, NTFS ADS, Windows reserved device names) | `rejectTraversal: true` by default; `sanitizeEntryPath()` for external sinks | CWE-22 / CWE-67 | `ZIP_PATH_TRAVERSAL` | `extract --skip-unsafe` (skip, never write) | +| Decompression bombs (high ratio, nesting, entry floods) | per-entry and total output caps, ratio bound, entry-count cap — enforced *during* inflation | CWE-400 / CWE-409 | `ZIP_LIMIT_EXCEEDED` | `--max-entry-size`, `--max-total-size`, `--max-ratio`, `--max-entries` | +| Symlink entries redirecting extraction | `rejectSymlinks: true` by default | CWE-59 | `ZIP_SYMLINK_REJECTED` | `extract --allow-symlinks` (target text as data) / `--skip-symlinks` | +| Overlapping entries | always-on overlap detection over central-directory ranges | CWE-405 | `ZIP_ENTRY_OVERLAP` | none | +| Parser-differential smuggling (central directory vs local headers) | the central directory is authoritative; method divergence is fatal, name divergence is diagnosed | CWE-436 | `ZIP_CD_LFH_MISMATCH` | none | +| Ambiguous EOCD (trailing garbage, multiple candidates) | only a self-consistent EOCD closest to EOF is accepted; ambiguity is refused | — | `ZIP_EOCD_NOT_FOUND` | none | +| Zip64 field spoofing | Zip64 records cross-checked against every non-sentinel classic field | CWE-1288 | `ZIP_ZIP64_CONTRADICTION` | none | +| Duplicate entry names (shadowing) | `onDuplicate: 'error'` by default | CWE-694 | `ZIP_EXTRACT_DUPLICATE_PATH` | `--on-duplicate first\|last` | +| Integer overflow (> 2^53 sizes / offsets) | 64-bit fields read via BigInt and rejected above `Number.MAX_SAFE_INTEGER` | CWE-190 | `ZIP_VALUE_UNREPRESENTABLE` | none | +| Oversized names / extra fields / comments / central directory | `maxNameBytes`, `maxExtraFieldBytes`, `maxCommentBytes`, `maxCentralDirectoryBytes` | CWE-400 | `ZIP_LIMIT_EXCEEDED` | `--max-name-bytes`, `--max-extra-bytes`, `--max-comment-bytes`, `--max-cd-bytes` | + +The defaults (100000 entries, 1 GiB per entry, 8 GiB total, 1024:1 ratio, 4096-byte names, 65535-byte extra fields and comments, 256 MiB central directory) are the safe path for untrusted input; raising one is always an explicit decision. + +### The CLI's own guards + +The rows the CLI adds because it owns the process and the filesystem (the knowledge base §6 carries the full table): + +| Threat | Defence | Status / residual | +|---|---|---| +| Unbounded stdin / file buffering (memory exhaustion) | `--max-input-size` (4 GiB default) on every buffered read; streaming commands are constant-memory | `none` disables it with a visible warning | +| Symlink / junction planted inside `--output-dir` | `realpath` anchor of the nearest existing ancestor before `mkdir`, re-check after; refused with `E_SECURITY` | the realpath → open window: use an empty or trusted destination | +| File appearing between plan and write | exclusive `wx` open unless `--overwrite`; `E_IO` refusal | none | +| Partial output under its final name (failure or interrupt) | removed on failure; `SIGINT` / `SIGTERM` remove the in-flight file only, exit 130 / 143 | signals are POSIX-only in practice | +| `modify` laundering a hostile record into a canonical-looking archive | eager open + `verifyEntry()` on every re-emitted entry before the save (see below) | encrypted / stream-only-codec entries are copied as-is and counted | +| A `--codec` module shaping the writer silently | override announced (`warning:` line, `tier`); `create --parallel` refuses such a module | see Code Safety | + +### Data remanence (`modify`) + +The default `modify` save is the engine's append-only `save()`: the original bytes are kept verbatim and a new central directory is appended, so untouched entries are never recompressed — and **removed or replaced content remains recoverable** from the output file. `--compact` selects `saveCompact()`, a canonical rewrite (still no recompression) in which removed content is truly gone. The CLI prints an `info:` line whenever a destructive edit is saved append-only, and the engine emits the `ZIP_DEAD_BYTES_RATIO` diagnostic above 50 % dead bytes. 7-Zip's CLI is also known to mis-read the append-only layout (it does not honour the final central directory); ship `--compact` output when interoperability with 7-Zip matters. + +### `modify` verifies what it re-emits + +Because both save modes copy untouched records verbatim, `modify` must not launder a hostile archive into a clean-looking one. It opens the archive **eagerly** (overlaps and the central-directory ↔ local-header structure are checked before any edit) and, before `save()` / `saveCompact()`, calls `reader.verifyEntry()` on **every entry that will be re-emitted** (every entry not removed or replaced; renamed entries are verified under their original record): CRC-32, sizes and the local header against the central directory — one decompress pass, never a recompress. A lying record is refused with the entry named: `E_SECURITY` `ZIP_CD_LFH_MISMATCH`, `E_DATA` `ZIP_CRC_MISMATCH` or `ZIP_SIZE_MISMATCH`. Encrypted entries and entries whose registered codec has no `decompressSync` cannot be verified: they are copied as-is and counted in `verifySkipped`; an entry with an unregistered method is refused (`E_UNSUPPORTED`, load `--codec`). The check runs under `--dry-run` too and has **no opt-out** — an opt-out would write unverified bytes. The envelope reports `verified`, `verifySkipped`, `tier`, `changed` and `layout: append-only | compact`. + +### Forward reader trust caveat (`stream`) + +`stream` reads local headers **alone** through `iterateZipEntries` — there is no central directory to cross-check names, sizes, methods or attributes, so a hostile archive can present different content there than `list` / `extract` authoritatively report. Consequently `--preserve-mode`, `--allow-symlinks` and `--skip-symlinks` are refused in forward mode (`E_USAGE`), every JSON output carries `trust: "local-headers-only"`, a `warning:` line is printed at start, and every name written to disk goes through `sanitizeEntryPath()` + `safeJoin`. All size limits are enforced by output counting and CRCs are verified. Entries written with data descriptors carry zero sizes in their local header, so `--summary` reports `descriptorEntries` and `bytesKnown: false` rather than pretending. Custom-method entries can be listed and skipped but not decoded in forward mode (the engine's pump knows store and deflate): `--cat` / `--output-dir` on such an entry fail with `E_DATA` `ZIP_DECOMPRESSION_FAILED`, which `--skip-unsupported` does not cover — use `cat` / `extract --codec` on the complete file. Use `stream` only for input you cannot seek; prefer `list` / `extract` on a complete file. + +### Code Safety + +- No `eval()`, `Function()`, or dynamic code execution — with **one declared exception**: `--codec ` dynamically imports a user-supplied ESM module and registers its codecs (`registerCodec`, `setInflateImpl`, `setDeflateImpl`). It runs with the invoking user's privileges (the same trust as `node -r`), so it is honoured **only from argv**: `.zipnativerc.json` refuses the `codec` key (a hostile repository cannot run code when you type `zipnative list` inside it), a `batch --manifest` task carrying `codec` is refused unless the invocation itself passes `--allow-codec-load`, and a loaded module is reported truthfully. Registered codecs are **not confined to the reader**: the engine resolves methods 0 (store) and 8 (deflate) through the registry, so a module that registers either **replaces the built-in compressor** for `create` / `modify` — even under `--deterministic`, which pins only the engine's own encoder — and a sequential `create` announces it with a `warning:` line (silent under `--dry-run`); a module exporting `deflateImpl` replaces the sync deflate tier and shows up as `tier: "injected"` in the envelope unless `--deterministic` pins the engine's encoder (`pure-pinned`). `create --parallel` refuses (exit 2) a module registering method 0 / 8, and a `deflateImpl` without `--deterministic`, because the worker pool never sees the module and the envelope would lie. `batch --manifest` otherwise dispatches only to a fixed whitelist of CLI command modules. +- **No sockets.** No command opens a network connection; there is no flag that could. `doctor`, `govern` and `schema` are fully local. +- The CLI never post-processes archive bytes: what the engine writes is what is written to disk, so the engine's `deterministic: true` byte contract holds end to end. +- **Signals.** `SIGINT` / `SIGTERM` remove exactly the files being written at that moment (`src/utils/inflight.ts` registers a file only once the CLI created it) and exit 130 / 143; completed outputs and the original of `modify --in-place` are never touched. POSIX only in practice (Windows has no signals for child processes). +- **Supply chain.** The package ships the CJS bin only (`dist/cli.cjs`, no ESM build, no `.d.ts`, no source maps) plus `AGENTS.md`, `llms.txt`, `docs/data/errors.json`, `README.md`, `LICENSE` and `package.json` — 7 files. `publish.yml` re-runs the entire gate (typecheck, lint, tests with coverage, build, built-binary smoke, veraZIP), generates a CycloneDX SBOM with an exact-pinned, lockfile-installed generator (never an npx fetch inside the job that holds the OIDC token), packs the tarball, verifies its contents (bin, agent docs and error catalogue present; no maps, no tests), **attests both the SBOM and the tarball** with `actions/attest-build-provenance` (verify with `gh attestation verify zipnative-cli-.tgz -R Nizoka/zipnative-cli`), attaches them to the GitHub Release and publishes **that packed file** via **Trusted Publishing (OIDC)** with npm provenance (verify with `npm audit signatures`), so the attested bytes are the published bytes. CI also proves the bundle is byte-reproducible (two builds, one hash). CodeQL runs on every code push and PR, OpenSSF Scorecard on every push to `main`; every action is SHA-pinned and Dependabot keeps them current. + +### Not supported by policy + +- **Encryption, read or write.** ZipCrypto is cryptographically broken; the engine will never write it and does not read it in 1.x. Encrypted entries are detected (`isEncrypted`), listed, counted by `inspect`, reported as `skipped` by `verify` (and by `verify --entry`), skippable with `extract --skip-unsupported` / `stream --skip-unsupported`, copied unverified by `modify` (counted in `verifySkipped`), and refused on read with `ZIP_UNSUPPORTED_ENCRYPTION`. There is no password flag. +- **Multi-disk / spanned archives** — refused (`ZIP_UNSUPPORTED_MULTI_DISK`). +- **Archive repair / salvage** — structural problems are reported (`verify`, `inspect`), never guessed at. +- **Other archive formats** — none. + +### False conformance claims → veraZIP gate + +Every archive the CLI writes is validated against **ISO/IEC 21320-1:2015** by `scripts/validate-zip.mjs`, a validator vendored from the engine (`zipnative/scripts/validate-zip.ts`, commit `4f1bc36`) that raw-parses the bytes with its own reader and **never imports `zipnative`** — so it cannot attest the engine with the engine. `npm run validate:zip` builds the CLI, drives the built binary to write a 37-archive corpus (33 conformant, including 3 hostile-but-conformant archives — zip-slip, a Windows device name, duplicate paths — that pass the ISO profile and that `extract` must refuse; plus 4 raw-crafted negative canaries the validator must reject with a declared check id), and validates every file: the expected verdict is **33 PASS, 4 XFAIL, 0 FAIL**. An unexpected pass of a canary is fatal, and a coverage canary fails the run if a required check id has no canary. Level 0 always runs; level 1 foreign integrity tools skip visibly when absent and `VERAZIP_REQUIRED=1` fails closed in CI. The gate is blocking in `.github/workflows/verazip.yml` (Linux + Windows, on every push and PR — no path filter) and again before every publish. **Conformance is not safety** — hostile-but-spec-valid archives are exactly why the guards above exist. + +## Disclosure Policy + +We follow [coordinated disclosure](https://en.wikipedia.org/wiki/Coordinated_vulnerability_disclosure).

Context + +**What is zipnative-cli?** +The official command-line interface for [`zipnative`](https://github.com/Nizoka/zipnative) — a zero-dependency, pure-TypeScript ZIP engine (random access, secure-by-default extraction, streaming, deterministic output, incremental modification) whose 1.0 surface — 77 exports, 39 error codes, `deterministic: true` bytes — is frozen under semver. The CLI exposes 15 commands, grouped by purpose (the global `--help` shows the same grouping): + +| Group | Commands | +|-------|----------| +| Create & modify | `create`, `modify` | +| Read & extract | `list`, `inspect`, `cat`, `extract`, `stream` | +| Integrity & codecs | `verify`, `crc32`, `inflate` | +| Automation & meta | `batch`, `doctor`, `schema`, `completion`, `govern` | + +`schema` (self-validation + capability manifest) and `doctor` (capability pre-flight) support agent automation. + +**Philosophy:** +- Zero extra runtime dependencies — `zipnative` (`^1.0.0`) is the *only* dependency. +- Pure dispatch layer — **no ZIP parsing logic lives in the CLI**. The CLI owns argv, the filesystem, stdout/stderr and the agent contract; every byte of ZIP structure is the engine's. +- The CLI is the **filesystem trust boundary** — the engine never touches disk; `extract` / `stream` are the sinks and re-prove containment themselves (lexically and physically). +- Composable — every command reads from stdin and writes to stdout by default. +- **Offline, always** — no command can open a socket. There is no network opt-in. +- Never loosen a security default — opt-outs skip, they never write anything unsafe. +- Honest envelopes — what the CLI reports (`tier`, `layout`, `verified`, `trust`) is what the engine did. + +**Targets:** Node.js ≥ 22. The package is bin-only: one CJS bundle, `dist/cli.cjs` (no ESM build, no type declarations).

A token matching `-` is always a value. Combined short flags (`-lq`) are refused (`E_USAGE`, exit 2). Short aliases that take a value: `-i --input`, `-o --output`, `-d --output-dir`, `-e --entry`, `-f --format`; boolean short: `-q`, `-h`, `-V`. There is **no** `-l` alias for `--long`. A long flag given several times with string values is collected into a `readonly string[]` (`--remove a --remove b`). Helpers: `getStringFlag(flags, ...names)` (first value), `getStringFlagAll` (every value), `hasFlag`, `getBoolFlag`. `tests/docs/consistency.test.ts` pins the table to the USAGE text (a boolean flag appears without a `` placeholder, a value flag with one). + +### Core Bridge (`src/core-bridge/index.ts`) + +The **only** import point of the engine (`zipnative` and `zipnative/worker`). Grouped exactly like the core's own `src/index.ts` so it doubles as a coverage ledger of the frozen 77-export surface (mapped in §8). Two additions of its own: + +- `ensureCodecsReady()` — memoised `initNodeZipCodecs()`: resolves `node:zlib` once so every sync codec path runs on the `node-zlib` tier. Without it a CJS bundle silently runs the pure-TS tier (the core's probe cannot see `require` in CJS scope). +- `loadParallelZip()` — lazy import of `zipnative/worker` (never on the startup path) that also resolves the worker script URL through the package exports map (`zipnative/worker/zip-worker.js`) so a packager that flattens `node_modules` fails loudly instead of silently degrading to main-thread compression. + +`zipnative` and `zipnative/worker` stay **external** in the tsup bundle (see `tsup.config.ts`). + +### `prepareEngine` (`src/utils/engine.ts`) + +Called first by every core-touching command. (1) loads and registers every `--codec ` (argv only); (2) unless `--pure-codecs`, calls `ensureCodecsReady()`. Idempotent — `batch` tasks run in-process and call it again as a no-op. `doctor` makes the resulting deflate tier visible (`deflate-tier`, `deflate-pinned`). + +**Codecs serve both sides.** The engine resolves methods 0 (store) and 8 (deflate) through the codec registry, so a `--codec` module that registers method 0 or 8 replaces the writer's compressor for `create` / `modify` — even under `--deterministic`, which pins only the engine's own encoder. A module exporting `deflateImpl` replaces the sync deflate tier (`tier: "injected"`) unless `--deterministic` (then `pure-pinned`). `LoadedCodecModule.overridesBuiltin` lists the writer-resolved methods a module registers; the sequential `create` announces an override with a `warning:` line (silent under `--dry-run`), and `create --parallel` refuses (exit 2) a module registering method 0/8 (always) or a `deflateImpl` without `--deterministic`, because the worker pool is a separate bundle that never sees the module. `setInflateImpl` (a module's `inflateImpl`) is honoured by the sync and streaming reader paths (`cat`, `extract`, `verify`, `modify`, `inflate --sync`) but not by `createInflator` (the default `inflate` path) nor by the forward pump of `stream`. + +### `CliError` and the error mapper (`src/utils/error.ts`, `src/utils/ziperr.ts`) + +```typescript +class CliError extends Error { + readonly exitCode: number; // 1 runtime · 2 usage + readonly code: ErrorCodeValue; // one of the 13 E_* classes + readonly zipCode: string | undefined; // zipnative's frozen ZIP_* code, verbatim + readonly entryName: string | undefined; + readonly detail: ErrorDetail | undefined; // { limit, configured, observed } | { feature } | { expectedCrc, actualCrc } +} +``` + +`ziperr.ts` is the **only** place that reads `err.code` from the engine. `ZIP_TO_CLI` maps the 39 frozen codes to a class + exit code and is typed `satisfies Record` — a core minor bump that adds a code fails `tsc` here instead of leaking as `E_RUNTIME`. Every core call in a command is wrapped: + +```typescript +const reader = guard('Failed to open archive', () => openZip(bytes, options)); +// or: try { … } catch (e) { throw mapZipError(e, 'Failed to add entries', entryName); } +``` + +`mapZipError` returns `CliError`s unchanged, maps `ZipError` subclasses (class → `E_*`, `err.code` → `zipCode`, `entryName` from `ZipSecurityError` / `ZipDataError` or the caller's fallback, `detail` from `ZipLimitError` / `ZipUnsupportedError` / CRC-bearing `ZipDataError`), maps Node `ErrnoException`s (`ENOENT`, `EACCES`, …) to `E_IO`, maps the unwrapped node:zlib errors of the sync tier (`Z_DATA_ERROR` / `Z_NEED_DICT` → `ZIP_DEFLATE_CORRUPT`, `Z_BUF_ERROR` → `ZIP_DEFLATE_TRUNCATED`, both `E_PARSE`, so the class never depends on the codec tier), and everything else to `E_RUNTIME`. `buildErrorEnvelope` (utils/agent.ts) adds `error.remedy` — the CLI flag(s) or command that lift the refusal — from an explicit `CliError` option (`--overwrite`, `--max-input-size`) or the `ZIP_REMEDY` table (`ZIP_PATH_TRAVERSAL → --skip-unsafe (extract, stream)`, `ZIP_EXTRACT_DUPLICATE_PATH → --on-duplicate first|last`, `ZIP_LIMIT_EXCEEDED → the exact --max-* flag`, …; absent when nothing lifts it), mirrored in `docs/data/errors.json` `cli.remedy` and printed as a `remedy:` line in text mode. Exit code conventions: `0` success, `1` runtime / check failure, `2` usage; `130` / `143` after SIGINT / SIGTERM (§5). Two CLI-side rules keep the classes honest: an unsafe **entry name** that arrives as data (`modify --add/--rename/--add-dir`, `create --stdin-name`, manifest names) is `E_INPUT` (exit 1) with `entryName`, and a malformed **flag** is `E_USAGE` (exit 2). Every CLI-side `E_NOT_FOUND` (`cat`, `inspect --entry`, `stream --cat`, `verify --entry`) carries `zipCode: "ZIP_ENTRY_NOT_FOUND"` and names the remedy. + +### Determinism, dates and layout (`src/utils/zipops.ts`, `src/commands/create.ts`) + +- **Dates are UTC wall-clock.** `--date ` (`create`, `modify`) and manifest `date` values are read as UTC: a string without a zone designator gets `Z`, a date-only string gets `T00:00:00Z`, and the stored DOS fields are identical on every host regardless of `TZ`. DOS resolution is 2 seconds (odd seconds are floored, with a warning) and the range is 1980–2107 (a warning outside it). `now` and `--mtime` are local time and not reproducible. `epoch` (the default) is the DOS epoch, 1980-01-01 00:00. +- **Reproducible vs canonical layout.** `create --stream` and any `addStream()` entry (`--stdin-name` is always streamed) use the data-descriptor layout: the same content as the buffered layout, different bytes (an engine contract; Info-ZIP and bsdtar do the same to a pipe). The `create` envelope reports `layout: "buffered" | "data-descriptor"`. `inspect` separates the two questions: `determinism.deterministic = epochTimestamps && canonicalOrder && utf8Flags` (reproducibility) and `determinism.canonicalLayout = noDataDescriptors` (form); `--check deterministic` and `--check canonical-layout` (alias of `no-data-descriptor`) gate them separately. A `create --stream` archive is reproducible run-to-run (`deterministic: true`, `canonicalLayout: false`). +- **Order.** `--order canonical` (default) sorts by raw-name bytes. `--order insertion` keeps the argv order across inputs (each directory still walks in sorted `readdir` order — `walkPaths({ preserveInputOrder })`); a manifest keeps its `entries` order. EPUB `mimetype`-first: `zipnative create book/mimetype book/META-INF book/OEBPS --base book --order insertion -o book.epub` (`--base` rebases the names, inputs are looked up where they are), or a manifest with `order: "insertion"`. +- **Encoder pinning.** `--deterministic` pins the pure-TS encoder (`tier: "pure-pinned"`); without it bytes are stable per Node + zlib build only (`ZIP_NONDETERMINISTIC_CODEC` when a pinned date meets an unpinned codec). `--parallel` is byte-identical to the sequential writer per tier. A `--codec` module registering method 0/8 still governs the bytes under `--deterministic` (see `prepareEngine`). `--stream --deterministic` buffers each streamed entry whole before compressing it (the pinned encoder is whole-buffer). +- `--chunk-size` (with `--stream` or `--stdin-name`) warns outside 1 KiB … 16 MiB (the engine clamps). + +### The extraction sink (`src/utils/sink.ts`, `src/commands/extract.ts`, `src/commands/stream.ts`) + +The engine never touches the filesystem: `extractZipStream` yields `{ path, entry, stream() }` with `path` already run through `sanitizeEntryPath()`. `utils/sink.ts` is the **one** place that turns a sanitised path into a file on disk, shared by `extract` (plan-then-write) and `stream --output-dir` (write-per-entry, after applying `sanitizeEntryPath()` itself because the forward reader does not sanitise names). Guards, in order: + +1. **Lexical containment** — `safeJoin(root, path)` (`utils/io.ts`) proves the resolved target stays under the root before any I/O (`E_SECURITY` otherwise). +2. **Duplicate targets** — a case-folded key on case-insensitive filesystems (win32, darwin) and `--flat` collisions follow the same `--on-duplicate error|first|last` policy as the engine's own sanitised-path duplicates (`ZIP_EXTRACT_DUPLICATE_PATH` under `error`). +3. **Physical containment** — before `mkdir -p`, the nearest *existing* ancestor of the target directory is `realpath`'d and must sit under the root's `realpath`; the created directory is re-checked afterwards. A symlink or junction pre-planted inside the destination that points outside → `E_SECURITY` "Refusing to write through a link that leaves the output directory…", and nothing is created beyond the link. +4. **Exclusive open** — without `--overwrite` the file is created with `wx`, so a file that appears between the plan and the write is refused like any pre-existing one (no check-then-write window). A residual window exists only between the `realpath` check and the open; the documented posture is "use an empty or trusted destination". +5. **No partial output** — a failed write (CRC / size mismatch, I/O error) removes the partial file. + +`extract` drains the lazy extraction generator without decompressing anything (PLAN; the `stream()` thunks are deferred; existing files are refused unless `--overwrite`, `E_IO`), then streams each entry with backpressure (WRITE). `--preserve-mode` applies `getUnixMode(entry) & 0o777` to files (POSIX only, never setuid/setgid/sticky; directories keep the umask); `--preserve-mtime` applies the entry timestamp. + +Security defaults are the core's (`rejectTraversal`, `rejectSymlinks`, `onDuplicate: 'error'`, the limits). Opt-outs are skip-not-write: `--skip-unsafe` sets `rejectTraversal: false` (the engine silently drops unsafe names; the CLI lists them as `skipped: [{ reason: 'unsafe-path' }]`), `--allow-symlinks` writes the link **target text** as a regular file (a symlink is never materialised), `--skip-symlinks` drops them, `--skip-unsupported` skips encrypted entries and methods with no registered codec (`reason: 'unsupported'`). + +### Overwrite policy and in-flight outputs (`src/utils/io.ts`, `src/utils/inflight.ts`) + +Every command that writes a **file** refuses an existing one with `E_IO` "Refusing to overwrite existing file (pass --overwrite)." and leaves it intact: `create -o`, `modify -o`, `cat -o`, `inflate -o`, `extract`, `stream --output-dir`, `batch --task create` (directory mode). `--overwrite` replaces it. Writing to stdout (`-` or no `-o`) is unaffected. `modify --in-place` writes an unpredictable, exclusively created temp file `.tmp--<12 hex>` next to the target and renames atomically. A file being written is registered in `utils/inflight.ts` (`writeOutput` registers only a file it created; `writeFileStream` registers on open); on SIGINT / SIGTERM the handler removes exactly those in-flight files — never a completed output, never the original of `--in-place` — and exits 130 / 143 (POSIX in practice; Windows has no signals for child processes). + +### Diagnostics bridge (`src/utils/diagnostics.ts`) + +The CLI owns stderr, so the core never gets to use its deduplicated `console.warn` default. Every core call receives a sink's `onDiagnostic`; the engine's handler contract delivers *every* diagnostic (no dedup), and the CLI sink **deduplicates by `(code, entryName)`** — an entry read twice in one run yields one row — and presents: + +- **text mode** — one `warning: [CODE] entry 'x': message` / `info: [CODE] message` line on stderr, suppressed by `--quiet`; +- **`--json`** — nothing per diagnostic; the collected `DiagnosticRow[]` travels in the success envelope (`emitStatus({ …, ...sink.field() })`) or in the stdout report's `diagnostics` field (`list` / `inspect` / `verify` / `stream --format json`); NDJSON outputs print them as text on stderr (`progress()` lines, so `--quiet` suppresses them); `verify` renders the engine report's own list (`diagnosticRows`) unchanged; +- **`--strict`** — handled by the core (`strict: true`): the first diagnostic throws `ZIP_STRICT_DIAGNOSTIC` → `E_CHECK_FAILED` before any output byte. `verify --strict` is the exception: the report is printed, then the verdict is `E_VERIFY_FAILED` when any diagnostic was emitted. + +Which command can raise which of the 11 codes is tabulated in §5. + +### Limits (`src/utils/limits.ts`) + +Eight individual `--max-*` flags (one per `ZipLimits` key, `LIMIT_FLAGS`, CWE-tagged) rather than a JSON blob: they complete in every shell and are flat keys in `.zipnativerc.json`. Values are pre-validated (`E_USAGE` on malformed or zero values), so `ZIP_LIMIT_INVALID` is unreachable from the CLI; `none` disables a bound (`Infinity`) with a one-shot visible warning. `parseLimitFlags` returns `undefined` when none is set so the engine's defaults apply untouched; `effectiveLimits` merges for `doctor` and `inflate`'s default `--max-output`. The bounds also apply on the **write** side (`maxEntries`, `maxNameBytes`, `maxCommentBytes`, `maxExtraFieldBytes` on `create` / `modify`, `maxCentralDirectoryBytes` on `modify`). + +`--max-input-size ` (global; default 4 GiB; `none` disables with one warning) is CLI-owned, **not** a `ZipLimits` key: it bounds every *buffered* read — stdin (byte-counted, the read aborts) and files (size checked via `stat` before reading) — for `list`, `inspect`, `verify`, `extract`, `cat`, `modify`, `create --stdin-name` (buffered), `inflate --sync` and `govern verify-issue`. Exceeding it is `E_LIMIT` with `detail { limit: "maxInputSize", configured, observed }`. The streaming commands are not bounded by it. `doctor` reports it under `limits` (`data.maxInputSize`) and counts it as an override. + +| Memory profile | Commands | +|----------------|----------| +| Whole archive in memory (bounded by `--max-input-size`) | `list`, `inspect`, `cat`, `extract`, `verify`, `modify`; `create --stdin-name` without `--stream`; `inflate --sync` | +| Constant memory | `stream`, `crc32`, `inflate` (default path), `create --stream` (one chunk + the segment being copied) | +| Per-entry buffering | `create --stream --deterministic` (the pinned encoder is whole-buffer); `cat` of an entry whose `--codec` has `decompressSync` but no `decompressStream` | + +### I/O Helpers (`src/utils/io.ts`) + +```typescript +validatePath(p) // E_INPUT on ../ (also ..\) — applied to DATA-supplied paths only (manifest values) +assertStdinNotTty() // E_USAGE "No input: …" when stdin is a terminal and no path was given +readStdin(explicit?, maxBytes) / readFileOrStdin(path, maxBytes) // '-' = stdin; maxBytes = --max-input-size → E_LIMIT +openInputStream(path) // Readable for streaming commands (unbounded) +installEpipeGuard() // EPIPE on stdout/stderr → exit 0, quietly +assertJsonSizeLimit(buf) // 50 MB cap → E_INPUT +readJsonInput(path, what) // read + cap + JSON.parse (E_IO / E_PARSE) +overwriteRefused(path, entryName?) // the uniform E_IO refusal +writeOutput(bytes, path, { exclusive }) / writeStreamingOutput(chunks, path, opts) // stdout when path is undefined / '-' +writeFileStream(path, chunks, opts) // backpressure-aware; 'wx' when exclusive; registers in-flight +safeJoin(root, relPath) // lexical containment proof → E_SECURITY +pathExists(path) / unlinkQuiet(path) // existence probe / best-effort partial-file removal +captureStdout(fn, maxBytes) // batch --manifest --json: one task's stdout → buffer (64 MiB cap → E_LIMIT captureBytes) +readableToByteSource(stream) // Node Readable → engine ByteSource +``` + +Argv-typed paths (`--input`, `-o`, `--output-dir`, `--base`, `--config`, `--codec`, `--comment-file`, positionals) are the user's own filesystem authority: `../a.zip` or `-o ../out.zip` is ordinary shell usage and is **not** refused. `validatePath()` still applies to values that arrive as **data**: batch-manifest path flags and create/modify-manifest `path` values.

Add `--deterministic` (the pinned encoder in every worker; a `deflateImpl` is then irrelevant, a method-0/8 override still refused) or drop `--parallel`. + +### `modify` output looks wrong in 7-Zip + +7-Zip's CLI mis-reads the append-only layout (it does not honour the final central directory). Pass `--compact`; every other mainstream reader (unzip, bsdtar, Python, jar, Expand-Archive) and zipnative read the append-only output correctly. + +### `stream` fails with `ZIP_STREAM_TRUNCATED` or `ZIP_UNSUPPORTED_CD_LESS_DESCRIPTOR` + +The producer cut the stream, or the archive uses data descriptors the forward reader cannot delimit (store + bit 3, encrypted + bit 3, custom codec + bit 3). Download the whole file and use `list` / `extract`. + +### `stream` shows zero sizes, or fails with `ZIP_DECOMPRESSION_FAILED` on a custom-method entry + +Data-descriptor entries (every `create --stream` entry) carry zero sizes and CRC in their local header; the forward reader exposes no measured values, `--list` must inflate each such entry to find the next one, and `--summary` reports `bytesKnown: false`. Entries compressed with a `--codec` method cannot be pumped by the forward reader at all (engine limitation): the failure is `E_DATA`, may follow bytes already written, and `--skip-unsupported` does not apply because the method is registered. Use `list` / `cat` / `extract` on the complete file. + +### `Error: Path traversal detected` + +A **data-supplied** path — a batch-manifest path flag or a create/modify-manifest `path` value — contains `..`. Argv paths (`--input ../a.zip`, `-o ../out.zip`) are not checked. Rewrite the manifest with paths relative to its directory (or absolute paths). + +### Timestamps differ between machines + +`--date ` and manifest dates are UTC wall-clock and identical on every host; `--date now` and `--mtime` are local time and not reproducible; DOS resolution is 2 seconds and the range is 1980–2107 (warnings are printed when a value is floored or clamped). The engine renders `lastModified` from the DOS fields in local time, so the JSON instant of the same archive can differ between hosts with different `TZ` while the stored bytes do not — compare `dosDate` / `dosTime` under `--long`, or the archive hash. + +### Piping binary output + +`create` and `cat` write bytes to stdout by default. Redirect (`> out.zip`) or pass `--output `; read the `--json` envelope from stderr. A closed downstream pipe (`| head`) ends the process with exit 0. + +--- + +## 8. zipnative API Mapping + +Every one of the 77 exports of zipnative 1.0.0 (72 from `zipnative`, 5 from `zipnative/worker` — [`docs/data/core-exports.json`](data/core-exports.json)) mapped to its CLI touchpoint. "Bridge" means the export is re-exported by [`src/core-bridge/index.ts`](../src/core-bridge/index.ts); `tests/docs/consistency.test.ts` checks that every name below stays present. The **Reach** column grades each row honestly (per the 1.0.0 coverage audit): **capability** — the behaviour behind the export is exercisable from a command; **type** — re-exported (or aliased) for typing only, nothing user-visible depends on it beyond `tsc`. + +### Reading, random access, streams + +| Export | Kind | Reach | CLI touchpoint | +|--------|------|-------|----------------| +| `openZip` | function | capability | `openArchive()` in `utils/zipops.ts` — `list`, `inspect`, `cat`, `extract`, `verify --entry`, `modify` | +| `OpenZipOptions` | interface | capability | `openArchive(bytes, options)`;

Frequently Asked Questions + +### Why does `extract` refuse an archive that `unzip` opens? + +Because the archive has a shape the engine treats as hostile: a name with `..`, an absolute path, a Windows reserved device name (`aux.h` from a POSIX host), a symlink entry, two entries resolving to the same path, or overlapping / contradictory headers. `unzip` and friends forgive most of these; zipnative refuses by default and tells you the exact `ZIP_*` cause. Use `--skip-unsafe` / `--skip-symlinks` / `--skip-unsupported` / `--on-duplicate` to skip deliberately; overlaps and header contradictions have no opt-out. + +### How do I get byte-identical archives across machines? + +`create --deterministic`. Without it the bytes are stable for a given Node + zlib build only (the `ZIP_NONDETERMINISTIC_CODEC` diagnostic tells you when a pinned date meets an unpinned codec). Keep the DOS-epoch default (`--date epoch`) or an explicit ISO date (UTC wall-clock, host-independent) and avoid `--mtime` / `now`; `--parallel` is byte-identical to the sequential writer per tier. Prove it with `inspect --check deterministic` and `sha256sum`. Do not load a `--codec` module that registers method 0/8 unless you want its bytes. + +### Why do `create --stream` bytes differ from `create` of the same files? + +`--stream` (and any `--stdin-name` entry) writes the data-descriptor layout: sizes and CRC trail each payload because they are unknown when its local header is written. The content is identical and the archive is still reproducible run-to-run (`inspect` reports `deterministic: true`, `canonicalLayout: false`; the envelope reports `layout: "data-descriptor"`). Compare streamed and buffered outputs with `verify` / `inspect`, not with a hash, and gate the form separately with `--check canonical-layout`. + +### Why does `modify` decompress entries I did not touch? + +Because an append-only `save()` copies their bytes verbatim, and copying a lying record (CRC, sizes or local header contradicting the central directory) would launder a hostile archive into a clean-looking one. `modify` verifies every survivor (one decompress pass, never a recompress) and refuses with `E_DATA` / `E_SECURITY` + `entryName`; encrypted and stream-only-codec entries are copied unverified and counted in `verifySkipped`. There is no opt-out. + +### Why does `create --parallel` refuse my `--codec` module? + +The worker pool is a separate engine bundle: `registerCodec` / `setDeflateImpl` calls on the main entry never reach it. Rather than compress with `node:zlib` while reporting `tier: "injected"`, the CLI refuses a module that registers method 0/8 (always) or exports a `deflateImpl` (unless `--deterministic`, whose pinned encoder is the same in every worker). Drop `--parallel` for that module. + +### Why is my existing output file refused? + +Every file the CLI writes is created exclusively (`create -o`, `modify -o`, `cat -o`, `inflate -o`, `extract`, `stream --output-dir`, `batch --task create`): an existing target is `E_IO` "Refusing to overwrite existing file …" and left intact. Pass `--overwrite` to replace it. Writing to stdout needs nothing. + +### Which time zone do timestamps use? + +ZIP stores DOS date/time fields with no zone. `--date ` and manifest dates are read as **UTC wall-clock** (a string without a zone is UTC), so the stored fields — and the archive bytes — are identical on every host. `--date now` and `--mtime` use local time. On the read side the engine turns the DOS fields into a local `Date`, so `lastModified` in JSON is an instant that depends on the host's `TZ` while `dosDate` / `dosTime` (under `--long`) do not. + +### Is `--json` output stable? + +Yes. Envelope fields, the 13 `E_*` classes, the 39 `ZIP_*` causes and the report shapes are pinned by `schema` (`$id` embeds the CLI version) and by tests. New fields are additive. + +### Where do the security limits come from and how do I change them? + +They are zipnative's `DEFAULT_ZIP_LIMITS` (100000 entries, 1 GiB per entry, 8 GiB total, 1024:1 ratio, 4096-byte names, 65535-byte extra fields and comments, 256 MiB central directory), plus the CLI's own `--max-input-size` (4 GiB) on buffered reads. Override per run with `--max-*`, or per project in `.zipnativerc.json` (`{ "max-total-size": "32g", "extract": { "max-ratio": 4096 } }`). `none` disables a bound and warns. + +### Can I use zipnative-cli with stdin/stdout on Windows PowerShell? + +Yes. `Get-Content -AsByteStream a.zip | zipnative stream --list` and `zipnative cat a.zip x | Set-Content -AsByteStream x` work; for archives prefer `--input` / `--output` paths to avoid PowerShell's text-mode pipe conversions. Every sample ships as a `.ps1` next to its `.sh`. + +### What is the difference between `list`, `inspect` and `verify`? + +| Command | Opens | Decompresses | Purpose | +|---------|-------|--------------|---------| +| `list` | lazily | nothing | Enumerate entries fast | +| `inspect` | eagerly (local headers cross-checked, overlap table) | nothing | Forensic facts, determinism verdict, `--check` gates | +| `verify` | eagerly | every entry (or the `--entry` selection) | CRC / size / local-header agreement per entry — the integrity verdict | + +### Why does `modify` say my removed file is "recoverable"? + +The default `save()` is append-only: it keeps the original bytes verbatim and writes a new central directory, so untouched entries are never recompressed — and removed / replaced payloads stay inside the file. `--compact` rewrites the archive canonically (still without recompressing) so removed content is truly gone. 7-Zip's CLI also mis-reads the append-only layout. + +### Can the CLI open encrypted archives? + +No — by engine policy in 1.x (ZipCrypto is cryptographically broken). Encrypted entries are detected (`isEncrypted`), listed, counted by `inspect`, reported as `skipped` by `verify`, copied unverified by `modify` (`verifySkipped`), and refused on read with `ZIP_UNSUPPORTED_ENCRYPTION`. `extract --skip-unsupported` / `stream --skip-unsupported` skip them. Read-only AES decryption is a future consideration blocked on a core crypto-provider seam (see ROADMAP). + +### Does anything here touch the network? + +No. Not `doctor`, not `govern`, not `schema`, not `--json`. The engine never opens a socket and neither does the CLI. + +### Are there security considerations I should know? + +Yes — the defaults are the safe path: containment-proved extraction (lexical and physical), refusals for hostile shapes, CWE-tagged bounds always on, a bound on buffered input, no symlink ever materialised, no overwrite without `--overwrite`, exclusive file creation, partial files removed on failure or interruption, survivors verified by `modify`, `--codec` only from argv. When handling untrusted archives, tighten `--max-total-size` / `--max-ratio`, keep `--skip-unsafe` off unless you accept silently skipped entries, extract into an empty directory, and prefer `extract --dry-run --json` first.
