Mnemonics Php Laravel Package

Product Decisions This Supports

• Whether human-memorable secrets become a product surface. Any flow where a user must generate, write down, read back, or dictate a random string — account recovery codes, backup passphrases, device pairing codes, invite/referral tokens, one-time access links — is a candidate for "make it something a person can say out loud." This package lets you settle that UX question with a sprint-long spike and real output in front of users, instead of a roadmap debate.
• Passphrase generator in onboarding/settings: ship or skip? Gives you the evidence to choose between shipping a Diceware-style generator versus continuing to hand users opaque strings that get pasted into a notes app and lost. Support-ticket volume on "I lost my recovery code" is the metric that decides this.
• Build vs. buy on a bounded utility. The package is a thin, framework-agnostic generator over a wordlist. v3.0.0 is a modernization release (enforced type hints, BitArray::next(): void, removed unused Mnemonic::ENTROPY_BITS), not new capability. Honest framing: it is a reference implementation and decision accelerant, not a strategic dependency. A 1–2 day in-house build is a credible alternative and this package is a fair benchmark for that estimate.
• Runtime baseline coupling. v3.0.0 hard-requires PHP 8.3+, so adoption is no longer a pure utility call — it implicitly endorses a floor on your Laravel/PHP baseline. Sequence the platform decision first; the package follows, it does not lead.
• Standards-adjacent evaluation. If the roadmap includes crypto-adjacent features (seed-phrase backups, wallet-style onboarding, exportable recovery kits), this package forces the question of whether you need BIP-39/SLIP-39 conformance — a decision worth making deliberately rather than discovering mid-migration.
• Test fixtures, demo data, and documentation. Readable seed data, QA sample recovery phrases, and screenshots that don't look like garbage strings. Highest value per unit of risk in the entire package, and it requires no security review.
• A concrete word-count/entropy decision, made once and written down. At 11 bits per word (2048-word list), the arithmetic is: 4 words ≈ 44 bits (fine for invite codes and rate-limited pairing), 6 words ≈ 66 bits (reasonable for a displayed-once recovery phrase), 8 words ≈ 88 bits (approaching offline-attack resistance), 12 words ≈ 132 bits (BIP-39 territory — only if the list and checksum are standard). Undocumented entropy is the most common review failure here; make it a documented product decision, not an engineering default.
• Non-decisions it does not support. It should not drive pricing, platform expansion, or anything customer-facing at scale. At 4 stars, 0 dependents, and a low opportunity score, it is an ingredient, not a product bet.

When to Consider This Package

Consider it when:

• You are already on PHP 8.3+ (a hard v3.0.0 gate) and need mnemonic output inside an existing Laravel service rather than standing up a Node or Python sidecar for one function. If you're on 8.1/8.2, scope the PHP upgrade as its own initiative — a 4-star utility should never drag your runtime baseline forward.
• The requirement is low-stakes and human-readable: invite codes, device pairing phrases, support-friendly identifiers, demo/seed data, QA fixtures. This is the correct day-one use case.
• You can wrap it in exactly one adapter class and keep the package namespace in a single file in your codebase. That file is your entire blast radius when upstream churns, and it is what makes the fork option cheap.
• You need to prove a UX hypothesis quickly — "will users actually write down six words?" — and a one-sprint spike beats a written spec.

Look elsewhere when:

• The phrase protects assets — financial, health, or anything a support agent shouldn't be able to reset. Wordlist bias, checksum correctness, constant-time handling, and RNG choice are none of them settled by a package with one maintainer and zero dependents. Use it as a prototype that buys you a sprint to scope an audited, standards-compliant replacement — and say that out loud in the design doc so the next person doesn't assume it was a considered long-term choice.
• Interoperability matters. If a user would ever restore this phrase in another product, you need BIP-39/SLIP-39 conformance and this is the wrong tool. Decide before the first migration ships — cheap now, expensive later.
• You need enterprise support, SLAs, or a security questionnaire answered. Nothing here survives procurement review.
• Your critical path would depend on it. MIT license, ~single-file surface, one maintainer, 4 stars, 0 dependents, and release metadata that is internally inconsistent (a v3.0.0 date preceding the advertised latest-release date). Assume you may fork within two quarters; vendor at a verified, pinned tag. dev-main is not a strategy.
• Extension or customization is the actual requirement. There is no service provider, no facade, no config, no I/O — the extension points are the adapter class, the config file, and the word count. That's the whole surface. If you need more, build it.

How to Pitch It (Stakeholders)

To executives (one paragraph): We have a recurring product question — should the codes and recovery strings we give users be something a human can actually read, write down, and say out loud? Today we ship opaque strings, users lose them, and support absorbs the cost. There is a small open-source PHP library that generates word-based phrases, and it lets us answer that question in about a week with something real to put in front of users, instead of a six-week build. It is free (MIT), it is not a platform commitment, and it does not touch pricing or our customer-facing roadmap at scale. The one caveat: it requires PHP 8.3, which is an upgrade we should be doing anyway — the library is the trigger, not the reason. Recommendation: approve a one-sprint spike, scoped to invite codes and demo data only, with a written decision at the end on whether human-readable secrets become a real product surface.

To engineering (the terms of the deal): We are adopting this as a reference implementation, not a dependency. Containment is the whole strategy:

• One adapter class, one service-provider binding, one config file. The package namespace appears in exactly one file. Every controller injects the adapter; nobody uses \Owenvoke\Mnemonic directly.
• Never touch internals. No subclassing Mnemonic, no referencing the removed Mnemonic::ENTROPY_BITS, no type-hinting BitArray. v3 changed type hints across all classes and altered a method signature for language-version reasons, not defect reasons — that pattern predicts recurring churn with no corresponding benefit. If you need a bit of the package's behavior, copy the logic into the adapter.
• Own the entropy or read the source. First task is answering one question in src/Mnemonic.php: does it accept entropy as an argument, or call random_bytes() internally? If you can pass entropy in, do it — the package degrades to a pure encoder, the safest possible outcome. If it generates internally, read the RNG call before this touches anything user-visible. Also count the words in the bundled list (2048 = 11 bits/word = BIP-39 English) and record the list's provenance and license — if you can't name the list in a security review, you don't have a security review.
• Pin ^3.0, verify actual VCS tags (don't trust registry dates), commit the lockfile, and note the PHP floor in the PR description. Vendor at a pinned tag if phrase generation lands on any critical path.
• Treat the output as a credential if it is one. Store a hash, display the plaintext exactly once, normalize on input (lowercase, collapse whitespace/hyphens — hand transcription mangles both), and never log it — dd() in tinker, Log::info() debugging, Telescope, and exception context all capture payloads and will deposit it in storage/logs/laravel.log and the error tracker. Re-read config/logging.php before shipping.
• Rate-limit any endpoint that mints phrases. Not for entropy reasons — an unthrottled "generate me a code" route is a free database-write primitive.
• Test the seam, not the library. Mock the adapter in feature tests; keep one separate unit test against the real adapter asserting word count and shape. That second test is where you catch an upstream wordlist or separator change on the next composer update.
• Time-box the bet. If phrase generation proves out, the follow-on decision is build-in-house or adopt an audited BIP-39 implementation — not deepen the dependency. Budget that conversation into the spike's exit criteria.
