Registration is recorded per pack id, and every hook from a collapsed load carries only the id the collapse kept — so a policy declared by the non-winning record's manifest and absent from the artifact left that pack in neither the failure map nor the registered map, and `missingGuards` skips a pack in neither. Nothing registered the policy and nothing denied on its behalf: the machine reported itself enforcing a scope that was running nothing. Registrations are propagated to every pack id behind the artifact now, so the pack that selected the missing policy is measured against what actually loaded (#738) + +- A broken artifact two packs share now fails closed for BOTH of them. Packs with identical entry bytes collapse to one load so the module imports once, and a load failure is recorded per PACK ID — so the collapse left one id holding the merged record and the other got no failure at all. `missingGuards` skips a pack missing from both the failure map and the registration map, so the second pack's selected policies were absent, unguarded, and unreported: a syntax error in a shared artifact guarded the first pack's tools and silently allowed the second's. Every id behind an artifact path is kept now and a failure is recorded against all of them, for a failed import and for a missing file alike (#738) +- The stand-in policy for several missing guards stops denying pairs no pack asked to guard. Its matcher unions the two axes independently and the policy registry ANDs them, so guards scoped to (PreToolUse, Bash) and (PostToolUse, Write) produced a matcher that also caught (PreToolUse, Write) and (PostToolUse, Bash) — a cross product of scopes neither pack declared. The matcher cannot be narrowed without losing dispatch, since a policy that is never called cannot decide anything, so it stays a superset and the pairing is settled during evaluation, where the real event and tool are known (#738) + +- Two failed packs no longer block more than either one did. When several packs are unavailable at once, one policy stands in for all of them, and its matcher unioned the events but left `toolNames` out of the combined object entirely — which reads as "every tool". So a single failed pack scoped to `Bash` denied `Bash`, and two of them denied `Write` and `Read` as well: combining two limited scopes was producing a larger one. Both axes union by the same rule now, narrowing only where every guard was narrow (#738) +- An audit whose resume could not be honoured no longer counts the same findings twice. The cache decides a transcript grew and hands back a prefix result plus a byte offset, but the READER is what discovers the offset is no longer good — a transcript truncated or rewritten under it — and it answers by reading the whole file instead. The prefix was merged onto that whole-file result regardless, so every finding before the offset was counted twice and the audit reported more than the transcript contained. The merge now asks whether the scan actually resumed, rather than whether a prefix existed (#738) + +- Bash extended globs are compiled instead of ignored. Three of the five operators — `@(`, `+(` and `!(` — begin with a character that means nothing on its own, so a token carrying one was not recognised as a pattern at all: `rm -rf ~/.f@(ailproofai)` never reached the glob check and deleted the state through the guard that cannot be switched off. `@()`, `?()`, `*()` and `+()` are now compiled as the groups-with-a-quantifier they are, recursing into their alternatives rather than escaping them, and `!()` — a negation a regex cannot express against a path segment — becomes `[^/]*`, a superset. The same trailing-character bug the braces had was underneath it: the strip that removes a subshell's parentheses (`(cd x && rm y)`) also removed a pattern's, so `~/.f@(ailproofai)` arrived as an unterminated group; the glob scan keeps both spellings now and tries the stripped form as well (#738) +- A pack that fails to load no longer denies agents it was never scoped to. The registration path skips a pack whose `clis` excludes the running agent, and the fail-closed path did not — so a pack scoped to `codex` that failed its digest check denied on `claude` too, locking an agent out over enforcement it was never configured to have, until a human repaired a pack it does not use. The scope is carried on a pack that failed before it could even be resolved, and — like an unreadable `match` — an unreadable scope means every agent rather than none, so a `clis` that is not a list of names cannot narrow the deny away (#738) + +- A shell bracket expression is translated before it is compiled, instead of being copied into a JavaScript regex verbatim — which read two of its spellings backwards. POSIX negates with `!`, so bash expands `rm -rf ~/.f[!b]ilproofai` straight onto the state directory while JavaScript read `[!b]` as "either `!` or `b`" and matched nothing: a one-character bypass of the guard that cannot be switched off. A `]` in the FIRST position is a literal `]` rather than the end of the class, so scanning for the next `]` closed `[]a]` on the wrong character, and a POSIX class carries a `]` of its own, which ended `[[:alpha:]]` early and left a stray literal behind. Anything exotic — a collating symbol, an equivalence class — now becomes `[^/]`, which reaches at least as far as the original; widening is safe where narrowing never is, because the decoy test is what decides. An unclosed `[` is a literal `[`, as it is to the shell, rather than a reason to answer "names nothing" (#738) +- `policies add` no longer refuses a pack because an UNRELATED one shipped identical bytes. An id is bound to the origin it first came from, so a second source for the same id has to be an explicit removal — but the prior record is looked up by digest as well as by id, and the binding check did not ask which of the two it had got. A pack from another repository that happened to build byte-identical output was rejected with `pack id X is already installed from Y`, naming an id the user had not asked for and offering a removal that would not have helped. The check now applies only when the ids actually match (#738) + +- `policies add` no longer claims to know something it inferred. When an incoming pack ships the same artifact bytes as one already installed under a different id, the old record is absorbed and its selection carried over — the right default, because a publisher renaming a set must not reset everyone who had narrowed it. But identical bytes are the only evidence there is, and they cannot tell a rename from a second pack one repository builds from the same source, so reporting it as "same policies under a new name" stated an inference as fact about a record the user installed on purpose. The line now says what was observed, that absorbing was the inference drawn from it, and how to restore the other pack if the inference was wrong (#738) + +- A glob that spells `~/.failproofai` without the letters in it no longer walks past the always-on state guard. The floor that decided whether a pattern was aimed at the state was a literal `fail` substring test — which is exactly the letter a metacharacter stands in for — so the pattern was thrown out before it was ever compiled: `rm -rf ~/.f*ailproofai`, `.[f]ailproofai`, `.fa*lproofai`, `.fa[i]lproofai`, `.f{a,b}ilproofai` and `$HOME/.f*ailproofai` all deleted the state through the one guard nobody can switch off. The floor is computed from the pattern's REACH now, the same way the match is: compile it once, require that it hits the state, and reject it if it also hits anything ordinary. `rm -rf *` and `rm -rf ~/.*` stay allowed because they sweep `node_modules` and `~/.config` too, and `rm -rf /tmp/test-failures*` because it reaches no state path at all. Brace expansion is performed BEFORE the pattern is compiled, in the order the shell does it — compiling `{a*,x}` as an alternation of escaped literals put a literal `*` in the pattern, so `~/.f{a*,x}ilproofai`, which the shell turns into `~/.fa*ilproofai` and then into the directory itself, read as naming nothing. Expansion is bounded on WORK rather than on nesting depth, because a depth cap that RETURNED its half-expanded words handed a still-braced word to the same compiler, so seventeen levels of `{x,{x,…{x,a*}…}}` — legal shell, with a branch that becomes `~/.fa*ilproofai` — came out matching nothing again; running out of budget now collapses every remaining group to `*`, a superset, at any depth in a single pass, which keeps an oversized token decidable rather than a way to stall the hook path. The glob scan also keeps its braces now, where the leading/trailing strip that exists for shell groups (`{ cmd; }`) used to eat the one closing `~/.{fail*,zz}`. Every `/`-delimited prefix is tried rather than the whole token — naming a file INSIDE the state is naming the state, so `shred ~/.f*ailproofai/policies-config.json` no longer passes on the grounds that it could not equal the directory (#738) +- A pack whose manifest declares a `match` nobody can read no longer defeats the fail-closed deny it was supposed to narrow. `match` was validated as "is an object" and nothing further, so `events: "PreToolUse"` — a string where a list belongs — was iterated character by character and narrowed the guard to `["P","r","e","T","o","l","U","s"]`, a set matching no event that exists: the pack failed to load, the deny fired on nothing, and the machine ran unguarded with enforcement that reported itself present. `events: 5` was worse, throwing `number is not iterable` on the hook path. Unreadable metadata now WIDENS the deny instead of narrowing it, on the principle that a scope derived from something nobody can parse says nothing true, and the manifest refuses the shape outright at install time, where the publisher can still fix it (#738) + +- `block-failproofai-commands` — the one policy no config can switch off — stops an agent emptying `~/.failproofai` through a command that never says `rm`. The check was one verb list, and `find ~/.failproofai -delete` names none of its words; deleting `policies/packs/installed.json` leaves a machine that reads as FRESH rather than broken, so fail-closed never fires and every pack policy silently stops running. The verb list is now an allowlist of commands that can only READ, which is a list that can be finished — a blocklist miss disables enforcement silently, an allowlist miss denies a command the operator can see. That closes an interpreter (`python3 -c 'shutil.rmtree(...)'`, `perl`, `node -e`), `git clean`, `sed -i`, `gio trash`, `install`, `tar --overwrite`, `chmod 000`, and `cp /dev/null `, which the old comment claimed was covered and the old regex never mentioned. The path is also carried across commands now — `cd ~/.failproofai && rm -rf .`, `D=~/.failproofai; rm -rf $D` and `find ~/.failproofai | xargs rm` each split the path from the verb and walked through. Reads stay allowed, and two that used to deny no longer do: any `>` in the segment matched, so `grep -r sudo ~/.failproofai 2>/dev/null` and `cat ~/.failproofai/config.json > /tmp/backup.json` were blocked, and `-exec` denied on the flag rather than on the command it runs (#738) +- The same guard runs on `Write`, `Edit` and `NotebookEdit`, not only on `Bash`. It was declared `toolNames: ["Bash"]`, so the shortest way to disable enforcement needed no shell at all: write `{"enabledPolicies":[]}` over `~/.failproofai/policies-config.json`, or an empty `installed.json`, and the policy was never called. `Read` is untouched (#738) +- A second adversarial pass over that guard closes 25 more ways through it, in two shapes. A name on the READ allowlist that turns out to have a write in it: `sort -o` and `curl -o` take a destination as a flag, `uniq IN OUT` and `xxd IN OUT` write their last operand, `sed 's/…/w '` writes with no `-i`, `find -fprint` truncates the file it reports into, `awk` runs `system()`, `rsync --remove-source-files` deletes what it copied, `git -c k=v -C clean` hid its subcommand behind a flag that swallows the next token, and `-exec` reused the read allowlist so `-exec cp /dev/null {}` and `-exec sed -i` emptied every file in the state. And a path reaching a command that never names it: `echo $(rm -rf ~/.failproofai)` ran under a head the walk approved, `A=~/.failproofai; B=$A; rm -rf $B` broke the one-pass variable scan, `for f in ~/.failproofai/*; do rm -rf $f; done` named the state only in the header, and `rm -rf ~/.failproof*` never spelled it at all — a glob is now compiled and tried against the paths it would have to hit (#738) +- That pass also fixed six reads the guard was denying, which is the failure mode that gets a guard worked around rather than reported: `bash -c 'cat ~/.failproofai/policies-config.json'` (the head was taken with its quote still on, so `'cat` matched no allowlist entry), `[ -f ~/.failproofai/policies-config.json ]` and `for f in …; do cat $f; done` (shell grammar reached the unknown-head branch), `cat ~/.failproofai/policies-config.json | tee /tmp/out.json`, and — the two that denied a delete in an entirely unrelated directory — `pushd ~/.failproofai; cat x; popd; rm -rf node_modules` and `(cd ~/.failproofai && cat x); rm -rf node_modules`, where the `cd` window never closed (#738) +- `failproofai publish` refuses an existing PRIVATE repository before it creates anything, instead of uploading three assets, exiting 0 and printing `policies add ` with a warning underneath saying nobody can run it. A pack is fetched over anonymous HTTPS with no credential to offer, so every install of a private one 404s — the publish reported success for a release that could not be installed, and left assets behind advertising that dead route. The refusal names the repository, says why no install can work, and gives both ways out: make it public, or publish it with `--allow-private` for somebody who genuinely wants a private pack and will hand the assets over another way. That flag still warns, and prints the warning INSTEAD of the install lines rather than beneath them. A repository publish creates is public by construction, so only reuse is affected (#738) +- `failproofai publish --help` describes that refusal instead of the behaviour it replaced. The screen still promised "an existing private one still publishes, and warns", and named `--allow-private` nowhere at all — so the command's only documentation told a publisher the run would go through, then exited 1, and left the one flag that gets past it discoverable only by triggering the refusal (#738) +- `failproofai publish` checks every source it is about to BUNDLE against the commit its version names, not just the entry and not just the tree. Four ways a file reached the artifact without reaching the commit are closed by one check: a file `.gitignore` hides (`git status` omits ignored paths even with `--untracked-files=all`), a modified sibling under a tag (tag inference looked only at the entry while publish bundles every discovered file), a source reached through a symlinked directory (`--show-toplevel` resolves symlinks and the source path did not, so every source read as never committed), and a policy file that is itself a symlink out of the repository (its blob in HEAD holds the link's target NAME while the bundled bytes are the target's). The refusal names the offending files, and says `git add -f` for an ignored one because `git add -A` leaves it ignored and would loop (#738) +- A file the bundler inlines but discovery never names is checked too. `findEntry` recognises only files that import failproofai and call `customPolicies.add`, while the bundler inlines whatever those import — so an ignored helper was in every byte of the artifact and in no source list, and the manifest recorded a commit containing none of it. The relative-import graph is walked now (#738) +- `git status` output is parsed with `-z`. Git C-quotes a path containing a newline or a quote, so the parsed value was escape sequences resolving to no file, and a legal policy file named `guards -> final.mjs` was truncated by the rename split — either way publish refused to commit its own source over a filename it had mangled itself. A rename's original path is consumed by the entry that produced it rather than read as a record of its own, and both halves are staged so the rename lands whole (#738) +- `failproofai publish` measures its sources the way git spells them. `rev-parse --show-toplevel` answers with symlinks resolved, so naming an entry through a symlinked directory — `publish ~/policies/guards.mjs`, where `~/policies` links into a checkout — put every source outside the repository, refused a committed and untouched file as "never committed", and offered `git add -f`, which does nothing for it. It cuts the other way too: a policy file that is ITSELF a symlink out of the repository has a blob in HEAD holding the link's target name while the artifact carries the target's bytes, and asking only about the link's own path called that publishable and recorded a commit containing none of them (#738) +- A file the bundler pulls in is checked against the commit even though discovery never names it. `publish` finds POLICY files — the ones that import failproofai and call `customPolicies.add` — while the bundle inlines whatever those files import, so a plain `./patterns.mjs` of shared matchers is in nobody's source list and in every byte of the artifact. Ignored, it read as clean: `git status` reported nothing, the policy file beside it was committed, and the pack shipped bytes HEAD does not contain under a version naming HEAD — the same false claim an ignored policy file used to make, with a different file on the end of it (#738) +- `failproofai policies add --cli` with no agent named no longer installs a pack that guards NOTHING. It parsed as an empty list, which `installed.json` stored verbatim and the hook path reads as "guard no agent" — an empty array is truthy and contains nothing — so the install reported itself enabled while enforcing on zero CLIs, which is the worst shape a guardrail tool has: the report says it is on. `--cli` is the easiest flag to leave dangling, because the agent list stops at the first token carrying a `-` or a `/`, so both the pack source and the next flag terminate it. `--policy` and `--category` already refused an empty list; `--cli` now does too (#738) +- Two installed packs sharing one artifact no longer discard each other's selections. Packs whose entry bytes are identical collapse to a single load so the module imports once — resolved toward enforcement for the pack's EFFECT, and not, until now, for what it had enabled. Only the winner's list reached the hook tag and the hook path gates on that one list, so two packs with complementary selections registered one and silently dropped the other's policy; the fail-closed check ignores a pack absent from the registered map, so nothing reported it. `clis` had the identical shape, letting a pack scoped to one agent decide the scope for both. Both are unioned now, `null` meaning "all of it" and absorbing any list (#738) +- `failproofai policies remove ` refuses an ambiguous name instead of removing whichever pack it finds first. Ids are stored with exact equality, so `Acme/guard` and `acme/guard` are two rows on one machine — and the case-insensitive matching added moments earlier took the first of them. An exact match now wins outright, a loose match is used only when it is unique, and anything else lists the candidates and removes nothing (#738) +- A pack renamed by its publisher no longer reports more policies enabled than it enforces. The carry that preserves a selection across a rename fired on any record with no `enabled` — which is exactly how `--all` is stored — so `--all` after a rename announced the whole pack while the manifest still held one policy. The carry was dead on every path it was written for, since the prior record is already found by digest (#738) +- `failproofai policies remove ` accepts the name you actually have. Exactly one spelling used to work — the stored id, byte for byte — and it appears nowhere on its own, so every form a user could SEE or had TYPED was refused: the case they installed it with (`add` takes any case, because GitHub does, then records the canonical id off the manifest), and the listing's own heading copied whole (`FailproofAI/policies@06b802b63f4f`). A pack whose owner happens to be lowercase removed on the first try, which made this look like one particular pack being unremovable rather than a name-matching bug. Now case-insensitive, with an `@` suffix dropped — and the reply names the id the machine holds rather than echoing back what was typed (#738) +- `failproofai policies add --cli` with no agent named is refused instead of installing a pack that guards nobody. It parsed as an empty list, which `installed.json` stores verbatim and the hook path reads as "guard NO agent" — so the command exited 0, printed `enabled (1/3, the pack's defaults)`, and left a pack enforcing nowhere. `--cli` is the easiest flag on the line to leave dangling: the value scan stops at anything carrying a `-` or a `/`, so the source and the next flag both end the list rather than joining it. Now refused the way `--policy` and `--category` already refuse an empty list, before anything is fetched (#738) +- `failproofai policies add --all` enables the whole pack rather than the selection you had under its old name. A rename is absorbed by artifact digest and the old id's selection is carried onto a record that names none — right when nobody expressed an opinion, wrong for a caller who just said "everything". The install reported the full catalog and wrote the old one-policy list: three policies on screen, one enforcing (#738) +- `failproofai policies` stops telling you to install a pack you already have. The listing counts ENABLED policies, so a pack installed with everything switched off reached zero the same way an empty machine does — and got the same advice, which would have changed nothing: the selection is what is empty, not the shelf. It now says so and points at the picker (#738) +- Toggling a policy in the dashboard moves the row you clicked, not every row that shares its name. A pack policy name is unique only WITHIN its pack, so two installed packs each declaring `block-sudo` produce two rows — and the optimistic update matched on the name while the write targeted `(packId, name)`, flipping the other pack's switch on screen with nothing persisted behind it until a reload silently put it back. The row list keyed on the bare name too, which made the two rows one React key (#738) +- The dashboard shows a pack the parameters saved for THAT pack. Its read side kept its own copy of the evaluator's bare-name fallback with the pack scoping left off, so a third-party pack that happened to declare `block-sudo` was shown the parameters saved for ours while the evaluator gave it none of them. The configuration modal seeds its inputs from what the row displays, so opening one and pressing Save wrote our pack's values under the stranger's own key — where they then really did take effect. Both sides read through one function now, and the fallback is our pack's alone on both (#738) +- `failproofai policies` stops calling every parameter you saved in the dashboard a typo. The listing checks each `policyParams` key against the names installed packs carry, and it knew only the BARE ones — so the moment the dashboard started writing the pack-qualified `pack//` key the evaluator actually reads, every configured parameter was reported as an "unknown policyParams key — possible typo" and shipped as a `policy_params_validation_warning` event, while that key was in fact the only spelling that takes effect. Both spellings are known now, built with the same helper the dashboard and the evaluator use, and a key naming no installed policy is still flagged (#738) + +## 1.0.2-beta.8 — 2026-08-26 + +### Features + +- Packs version by the COMMIT they are built from — its short sha, twelve characters. Nothing to pick and nothing to count: publish the same source twice and the version is the same, because there is nothing to increment. Read from the tree rather than the repository's releases, so a fresh clone and an air-gapped machine agree and neither asks GitHub what happened before. Twelve rather than git's seven, since seven collides in a large repository and a version that stops being unique means two artifacts claiming one name. It refuses rather than guessing where the claim would be false — outside a git checkout, and on a tree with uncommitted changes — and `--version` overrides both. A sha does not order, which is what `policies show / --releases` is for (#738) +- A pack records the git commit it was built from — in its manifest, in the release notes, and in `installed.json`. PROVENANCE, deliberately not verification: `sha256` is still the only thing that decides whether the bytes are the ones that were published, and this answers the question a digest cannot, which is what source produced them. Absent and harmless when the pack was published from a directory that is not a git checkout (#738) +- `failproofai policies add /@a1b2c3d` installs the release built from a commit. Ambiguous prefixes are refused with the candidates listed rather than resolved to a guess, and a string that matches no commit falls through to being a literal tag, because a repository may genuinely have one named that. The lookup is the only place the CLI asks GitHub what exists — every ordinary install still constructs its URL from owner/repo/tag and discovers nothing (#738) +- `failproofai policies show / --releases` lists every version a pack has published, with its commit, policy count and which one is installed here. ONE request, however long the history: `publish` writes those counts into the release body, which `GET /releases` returns inline — the obvious version downloads a manifest per release and gets slower the longer a pack has existed. A release that recorded nothing shows `—` rather than being fetched to fill in (#738) + +### Fixes + +- `failproofai publish` does the git work itself instead of handing it back. With no checkout it runs `git init`, stages everything except the build output, and commits — there is no history to disturb, no branch to confuse and no unrelated work to sweep up, so it is safe to just do. With a dirty tree it commits ONLY the policy files it is about to bundle, and REFUSES when anything else is dirty, naming those paths: `git add -A` there would sweep up a half-finished edit or a scratch `.env`, and "publish committed my unrelated work" is a far worse surprise than being asked. TTY only — a commit made in CI exists on the runner and nowhere else, so `--version` remains the answer there (#738) +- `failproofai publish` settles a policy folder git reports as ONE untracked directory. `git status --porcelain` does not list the files inside a wholly untracked directory — it prints `?? policies/` once — so a brand new folder of policies inside an existing checkout matched no policy file, read as somebody else's work, and publish refused it by naming the folder itself as "not this command's to commit". The bootstrap case the whole feature exists for, and invisible from the repository root, where an untracked file is reported individually (#738) +- `failproofai publish` no longer starts a SECOND git repository inside the first. A checkout that has been initialised but never committed to answers nothing to `rev-parse HEAD`, so publishing from a folder below its root took the no-repository branch and ran `git init` there — committing into a repository the author will never push, while the parent still showed an untracked `policies/` and no commit at all. That is a version naming provenance nobody can resolve, minted at a terminal, which is the one thing that path exists to prevent. It refuses now, because everything in an unborn checkout is untracked and the only add that would work is one sweeping the parent's whole work tree. At the checkout's own root it still commits, and stops claiming to have started a repository that was already there (#738) +- A `--cli` narrowing survives the next `policies add`. `installed.json` rows are replaced wholesale, so an add that named no agents wrote none — and a pack you had scoped to Claude silently started guarding every supported agent, enforcing on ones nobody picked. The same shape as the `--category` bug beside it, in the widening direction, which is the worse one. The interactive picker is deliberately exempt: ticking every agent records nothing so a CLI supported later is included too, and carrying there would make widening back to all impossible (#738) +- `failproofai policies add --category X` ADDS to what is already on instead of replacing it. Following the pack README's own path — take the defaults, then add a category — left you with six policies on where you had started with ten, silently, from a command whose first word is `add`. The interactive picker still replaces, because its list is the complete answer and unticking something has to be able to turn it off (#738) +- `--version` on a dirty tree no longer records the commit. It let the publish through and then wrote `commit` into the manifest anyway — the exact false claim the dirty refusal exists to prevent, reachable by taking the escape hatch that refusal recommends (#738) +- `failproofai policies show / --releases` stops being wrong in three places at once. The published column labelled every span one unit too fresh — a release from yesterday read `1 hour ago`, one from six months ago read `5 weeks ago` — which is the opposite of what a staleness column is for. `incomplete` was decided by COUNTING attachments rather than naming them, so any repository that ships three binaries per release read as installable and one that attached nothing at all read as fine. And the install hint was derived by a second pass that disagreed with the table: a release with an empty tag produced the uncopyable `policies add owner/repo@`, and a release carrying none of the three assets was offered as the thing to install (#738) +- `failproofai policies show / --releases` sorts by when each release was PUBLISHED, instead of trusting the order GitHub returned. That endpoint orders by `created_at`, and a release's `created_at` is the date of the COMMIT its tag points at rather than the moment the release was cut — so two releases made from one commit tie, and the tie broke backwards on our own pack repository: an older release sat above a newer one and the install hint offered the older of the two. It mattered little while a version sorted by itself and matters now that a sha does not, since this list is the only place "which of these is newest?" is answered. A release carrying no usable date sinks rather than floats (#738) +- A text prompt shows the default it would apply. `failproofai publish` offers your account and the folder name, and nothing on the screen said return would take it — which is the entire job the default was there to do, so people typed it out again. `promptText` now renders `↵ ` ahead of any hint it is given, so a prompt cannot be added without it; never on a masked one, because the reason a credential's characters are hidden is that the wizard is routinely run while screen-sharing (#738) + +## 1.0.2-beta.7 — 2026-08-26 + +### Features + +- Every `--help` screen is drawn by one renderer, so the twelve of them are one screen instead of twelve dialects. They were each a template literal — `USAGE` on one and `Usage:` on the next, a description column hand-counted per file, no version on any of them and no colour on any of them while the index they were reached from had all three. Section headings are now the brand's `━━ label ━━` rule everywhere, the description column is computed rather than counted, and the whole family is capped at 80 columns so help reads the same in a maximised window as in a tmux pane (#738) +- `failproofai --help` spends its lines on commands rather than on a manual: the sections breathe, the four that nobody types on their first day are named on one line instead of given a row each, and the shape and the links moved to a footer. Also drops a `config --connect` row that no longer describes how to connect (#738) +- One accent, three tones, on every sectioned surface: a pink lead into the section rule, pink for what you TYPE, dim for what it means. `rule()` is shared, so `policies`, `harness`, `pack list` and every `table` section moved with the help screens rather than being restyled one at a time (#738) +- `flush`, `backfill`, `migrate`, `update` and `uninstall` print a report with a heading and margins like every other screen, instead of bare sentences at column zero. The modules still return facts; the presentation lives in one place (#738) + +### Fixes + +- `failproofai policies --install` no longer opens a policy picker, and no longer pushes a stale `enabledPolicies` back into an installed pack. Wiring hooks is not choosing policies: it offered a second list — over the COMPILED catalog, which is not how policies arrive any more — and saved the answer to a key nothing else writes. `policies remove block-env-files` followed by `policies --install` put block-env-files straight back on, silently (#738) +- `failproofai config --token ` asks nothing at all on a terminal, not just off one. It still drew the Cloud question and the review prompt, so the one command that says "connect me, don't ask" asked twice. Only the sudo password is left, because no flag can supply it (#738) +- `failproofai audit --help` gets its description column from the same renderer as every other screen. It had its own hand-set constant, which is how `audit` and `config` ended up putting their descriptions in different places, and `--email
` wrapped across two lines — the flag on one and its placeholder on the next (#738) +- Deleted an unreachable `pack` branch in the CLI: `pack` is rewritten to `policies` above every dispatch, so the sixty-line help screen it carried — still advertising `pack list`, `pack add` and `pack build`, in a heading style nothing else used — could not be reached to notice (#738) + +## 1.0.2-beta.6 — 2026-08-26 + +### Features + +- `failproofai config` sets a machine up when there is no terminal, instead of refusing. It printed "needs an interactive terminal" and did nothing, and `installDaemonService()` had exactly one caller — the wizard — so no CI job, container or agent could reach the daemon-configured state at all. No flag: the command IS the request. Add `--token ` (or `FAILPROOFAI_CLOUD_TOKEN`) to connect to Cloud in the same run; the URL defaults to app.befailproof.ai. Exit 1 if anything asked for did not happen, including a key the server refused and a machine that could not reach root (#738) + +### Fixes + +- The audit's "already protected" split now counts policies that arrived in a PACK. It read `enabledPolicies` and nothing else — a key that predates packs and which `pack-store` never writes, since a pack records its selection in `installed.json` — so every finding read as slipping through however many policies were installed, and the number the audit leads with never moved. Measured before: identical 302 hits and 17 findings with nothing installed and with all 38 (#738) +- `policies add --cli` refuses a name that is not an agent, instead of installing and guarding nothing. `--cli claud` printed "Installed", exited 0, and applied the pack to no agent at all because the misspelling matched none (#738) +- `policies add --cli claude codex` keeps BOTH. The pack lane split on commas while the policy lane split on spaces, so a space-separated list was silently truncated to its first entry. Either spelling now works on both (#738) +- `policies add --scope project ` installs the pack instead of going looking for one called "project", and `-c ./file.mjs` is no longer read as the pack name — a flag's value could be taken as the positional whenever the flag came first (#738) +- The hook never waits forever for its payload. `readStdinPayload` is on the enforcement path — every tool call, on all eleven agent CLIs — and had no bound: its only early exit was `readableEnded`, which helps only when stdin is ALREADY closed. A parent that spawned the hook with a pipe it had not closed, or an inherited terminal, froze that tool call indefinitely with no output. A terminal now returns immediately and an open pipe gets a 10s clock, both reported rather than silent (#738) +- `failproofai config` run under sudo exits 1 instead of 0. It explained the problem and reported success, so a script carried on believing the machine was configured — `WizardAbort` had declared `running_as_sudo` since it was written and never once assigned it (#738) +- Our own pack has no short name any more: it is `failproofai policies add FailproofAI/policies`, the same shape anyone else's is typed in. `core`, `failproofai` and `official` are retired and say what to type instead rather than failing as unparseable (#738) +- `failproofai policies` and the first-run audit now say how to get policies when none are installed — setup deliberately installs none, so both surfaces used to be dead ends for a brand-new machine (#738) +- `failproofai publish` refuses a pack carrying two policies with the same name. A name is what `--policy` selects and what the picker toggles, so a duplicate made one of the pair unreachable and let the other's on/off state decide for both — reachable by accident whenever `publish --init` wrote a starter into a folder that already had a policy of that name (#738) + +## 1.0.2-beta.5 — 2026-08-25 + +### Features + +- `failproofai audit` resumes a transcript that GREW instead of re-reading it from byte zero. The cache was all-or-nothing per file, so a long-running session gaining one line was re-parsed and re-replayed in full — and the sessions that gain lines are the largest ones. Measured on a 29 MB transcript with one line appended: 14.0s to 2.4s (#738) +- `failproofai audit` no longer shells out to the `opencode` CLI once per session — it reads opencode's SQLite database directly, like every other SQLite-backed integration. Each spawn cost ~1.5s and there were three per session, which on a 30-session history was ~135s of a ~140s audit; measured 140s to 3s on the same machine, with byte-identical output (#738) +- `failproofai publish` asks where to publish instead of requiring `--repo`, defaulting to your account and the folder name — write policies in a git repo, run one command, answer one question (#738). Nothing prompts on a pipe or in CI, where flags remain the whole interface + +### Fixes + +- Stop `failproofai policies` warning about hooks in multiple scopes on a machine whose hooks are in one file — a user-scope-only CLI answered for every scope, and from `$HOME` a project path resolves to the user file (#738) +- `failproofai publish` with no arguments now publishes instead of printing its own help, which is what the help itself documents it as doing (#738) +- `failproofai publish --dry-run` works in a folder that has no git remote yet — the case a dry run exists for (#738) +- Create the pack repository empty rather than seeded, so the author's `git push` is a fast-forward instead of unrelated history — and the release tag names the commit the pack was built from (#738) +- Stop the dry run suggesting an entry file and a `--version` it had just worked out for itself (#738) +- `policies add core` no longer describes the core pack as shipped in the package, and `publish --help` no longer tells you to bundle by hand (#738) +- Publish now pushes the author's history to the repository it creates, so the branch tracks `origin` and a later bare `git push` works (#738) +- `publish --init ` writes `.mjs` rather than a file with no extension, which discovery skipped and no loader could import — so the starter file was invisible to the publish meant to pick it up (#738) +- `publish --init` no longer signs off with an entry path and a `--version` that publish works out for itself (#738) + +## 1.0.2-beta.4 — 2026-08-25 + +### Features + +- **Publishing a pack is two commands, and neither needs an argument.** `failproofai publish --init` asks what the pack is called and writes a policy that already blocks something real — the blank file was the hardest step, and a shape described in prose leaves a newcomer to hand-write their first registration and learn at publish time whether they got it right. Then `failproofai publish` works out the rest: it finds the policy file by CONTENT rather than filename (imports `failproofai`, calls `customPolicies.add`), so it finds `guards.mjs` and ignores an unrelated `policies.mjs`; reads the repository from the git remote in the FILE's directory rather than the shell's, because a policy living in another checkout is normal; creates the repository if it is missing, which was the last step that made "one command" untrue; and counts the version from what the repository has already published. Non-recursive on purpose — publishing a fixture or an example is the failure that avoids. (#738) + +- **Policies split across files publish as one pack.** One entry artifact is a real constraint — only the entry is content-addressed, so a multi-file pack could not honestly claim to be digest-pinned — but that constrains what is PUBLISHED, never how anybody writes. Splitting policies across files is normal past about three of them, and the answer used to be "go and configure a bundler" for the one mechanical step this tool already performs for its own pack. Several policy files in a directory, or one entry importing its neighbours, are now bundled into that single artifact with the same `bun build --external failproofai` that builds `failproofai/core`, and the file list is printed so what went in is visible. (#738) + +- **Versions are counted, not hashed.** A commit SHA names exactly where bytes came from and orders nothing: `a1b2c3d` against `f9e8d7c` says nothing about which came first, and nobody can say they are on the older one. The version is `--version` if given, else a tag on HEAD — somebody who tagged `v1.2.0` has SAID what the release is — else one past the highest the repository has published. Counted from the repository's own releases rather than anything local, so a fresh clone computes the right number and two people publishing from different clones cannot both mint `1.0.1`. Non-semver tags are ignored rather than parsed heroically. The dirty-file refusal moved with it and now applies only to the tagged path: a tag names a commit, so shipping edited bytes under it publishes what that commit does not contain, while a counted version names no commit and has no such problem. (#738) + +- **A pack chooses which agents it guards, and setup stopped asking.** Setup wires hooks into every supported agent, detected or not — hooks alone enforce nothing now that no policy ships, so wiring them everywhere costs a config entry and changes no behaviour until a pack arrives, while an agent installed next week is guarded from its first tool call instead of running unguarded until somebody re-runs setup. Which agents a pack guards moved to `policies add`, asked before the policy list because it is the coarser question and the one somebody can answer without reading thirty-eight descriptions. An absent `clis` means every agent and keeps meaning that when a thirteenth CLI is supported; an unrecognised agent name is KEPT rather than dropped, because dropping it would widen a pack back to every CLI — the one direction a narrowing choice must never move. (#738) + +### Fixes + +- **`publish` misread its own flags and published the wrong thing.** It found the entry file with the parser `policies add` uses, which knows that command's value-flags and not publish's — so `failproofai publish --id me/x --version 1.0.0` took `me/x` as the file and died on ENOENT. It only ever worked because every example wrote the path first. Found by writing the tests, not by using it. (#738) + +- **A tag disagreeing with the version reached the network before being refused.** Counting the version needs the repository, which moved the credential and repo lookup ahead of the tag check — so a bad `--tag` cost a request, and against a repository that did not exist yet it would have CREATED one for a publish it was about to refuse. An explicit tag is checked against an explicit version before anything reaches the network. (#738) + +- **`failproofai policies` claimed nothing was installed while listing an installed pack.** The check asked Claude Code and only Claude Code, so every machine guarded through one of the other eleven CLIs was told it had nothing — quietly while this only tinted a subtitle, and loudly once the listing began warning every policy shown was inert. Reported from a machine set up for codex. It asks every integration now. (#738) + +- **`dist-pack/` is ignored.** `publish` writes its three release assets there by default, and a publisher running the command inside their own repository should not find build output staged. (#738) + +- **Installing or removing a pack cold-rescanned the entire audit history to reproduce the answers it already had.** `engineVersion` keys every on-disk audit cache entry, and it folded in the identity of every installed pack — on the stated reasoning that packs "change what a machine would have caught". That is true of enforcement and was never true of this replay: `initReplay` registers `BUILTIN_POLICIES` and never reads the installed packs, so a pack cannot move an audit result. The key now hashes the builtin policy bodies and nothing else. Reported from a real machine where going from one pack to none re-derived 3056 transcripts to arrive back where it started — survivable when packs were rare, and not now that policies ARE packs. (#738) + +- **The audit no longer reaches for a vendored pack that cannot exist.** `initReplay` preferred the functions from a bundled `policy-pack/` copy where one was present, falling back to the compiled implementations otherwise. That branch was meaningful while the package shipped that directory; it stopped shipping it, so the branch could not fire in any published build and survived only to be misread as "the audit scores against whatever packs you have installed". It does not, and must not — an audit is a fixed yardstick, and one that changed shape with a machine's pack set could not be compared against its own history. `bundledPackDir` had no callers left and is gone. (#738) + +- **Both were checked to cost nothing rather than assumed to.** A machine with no packs already hashed as builtins-only, so its cache key does not move and its history stays warm; a machine with a pack installed rescans once and is then stable across every future pack change. The bundled policy bodies were fingerprinted before and after each edit (75,787 bytes, sha1 `15c77414caa39779`, unchanged throughout) because removing modules can shift bun's emission order and rename identifiers INSIDE the hashed function bodies — which would have rescanned every user for a change that touched no policy. (#738) + +## 1.0.2-beta.3 — 2026-08-25 + +### Fixes + +- **Unticking every policy in the pack picker installed the publisher's defaults anyway.** Reported from a real install: the picker highlights the defaults, you untick all of them, press enter, and the defaults arrive — announced as "the pack's defaults", which is the opposite of what was chosen and reads as if it had been asked for. `resolveSelection` decided whether a selection existed by testing `opts.only.length`, so an empty list — "install the pack, enable none of it" — was indistinguishable from passing no flags at all and fell through to the defaults branch. Presence of the field is the signal now, never its length. Two consequences travelled with it: `enabled: []` had to survive to disk as an array, because `[]` and `undefined` mean opposite things there (none, and all) and a reinstall would otherwise resurrect the defaults; and the zero case now says "none — the pack is installed and enforcing nothing" rather than printing a line that ends in a colon, which rendered the one outcome most needing an explanation as though something had gone missing. (#738) + +## 1.0.2-beta.2 — 2026-08-25 + +### Features + +- **Installing a pack chooses, instead of announcing what it chose.** `policies add ` took the publisher's `defaultEnabled` flags and printed the result afterwards, which turns a recommendation into a decision made on the user's behalf — by which point the policies are on their machine. A human at a terminal who names no flags now gets the pack's list first, defaults pre-ticked, grouped by category. It reads the MANIFEST only, so deciding about a stranger's pack still never downloads a stranger's code. Skipped entirely when `--policy`/`--category`/`--all` is passed or there is no TTY: a script asked a precise question and must get a precise answer, not a prompt it cannot see. (#738) + +- **Setup is one linear flow, with no fork at the front.** It opened by asking "Recommended or Customize?" — a question about the wizard rather than about the machine, unanswerable until you know the alternatives, which you learn by picking one. Recommended then took global scope, the detected CLIs and fifteen unseen policies. What is left is three questions in the order the machine needs them: the daemon (first, because it is the only step that needs a password), which harnesses, and whether to connect. Scope is not among them — it is global, always, because a project-scoped install guards the one directory the command was run from and silently leaves every other repo unguarded; `policies --install --scope project` is still there for someone who means it. The harness step is now always asked rather than inferred: Recommended used to skip it and wire failproofai into agents nobody named. (#738) + +### Fixes + +- **Every prompt keystroke redrew the screen as two writes, which is a blank frame.** The cursor-up-and-clear was its own `write()`, so a terminal could paint the CLEARED state before the new lines arrived — invisible on a local terminal, and a visible flash on every keypress over SSH or inside tmux, where the two writes cross a network or a multiplexer between frames. A repaint is now one write, wrapped in synchronized output (`DECSET 2026`) so the terminal holds the frame until the reset; terminals that do not implement it ignore an unknown private mode, so it costs nothing where it does not help. Found by running the house TUI guide's anti-pattern list rather than by looking at the output, which is exactly the kind of defect looking cannot find. (#738) + +- **A hand-wrapped warning fought the wrapper it was passed to.** The NOT-ENFORCING message was written as four pre-broken lines, and `warning` wraps each element it is given — so the author's line breaks became paragraph breaks and wrapped again inside themselves, leaving the word "them." alone on a line at 60 columns. It is prose now, and fills whatever width it is given. Verified at 40, 60 and 80. (#738) + +- **The policies listing said "not installed" directly above an installed pack.** It was reporting whether HOOKS are wired, which is a different question from whether policies exist — and it hid the state that actually matters, because a machine can hold thirty-eight policies and enforce none of them when no agent CLI is calling failproofai at all. That is the worst of the three states and it read as the emptiest. The header now says `N on · NOT ENFORCING` with a warning naming the cause. (#738) + +- **The TUI carried a character the design system forbids.** `⚠` takes EMOJI presentation on most terminals, and the brand rules are explicit that there is no emoji anywhere. It is `▲` now — one column, geometric like the `◆◇●○◼◻` already in use. The width matters as much as the look: the warning block hangs its continuation lines under a ONE-column marker, so an emoji-width glyph silently broke the very alignment it sat in. Section rules move to the brand's heavy `━━` eyebrow, with the light `─` kept for table sub-rules so the two levels read as different weights, and the `❋` dingbat becomes the actual `▮▮` brand mark. (#738) + +## 1.0.2-beta.1 — 2026-08-25 + +### Features + +- **The package stops carrying policies, and `policies add core` fetches them.** The tarball shipped `policy-pack/` — our policies as a real, digest-verified pack — so a fresh install already had them on disk and `pack add core` needed no network. That is exactly the thing this migration was meant to end: a pack shipped inside the binary is a policy set we chose for the user and wrote to their disk before they asked, and it gave OUR policies a delivery route no third-party pack could use, which is the opposite of what the lane exists to make possible. `policy-pack/` leaves `files` and `build`, `installBundledPack` is deleted, and `core` becomes a spelling of `FailproofAI/policies` — resolved in `pack-store` so the CLI and the dashboard cannot disagree about what the short name means, fetched, digest-verified and pinned like anybody else's. The build script survives, because publishing the core pack to its release still needs it. Offline now fails where it used to silently succeed, which is the honest answer: there is nothing local to install. (#738) + +- **Two things that would have been quiet breakages, checked rather than assumed.** The audit's cache key folds packs in by `id|version|sha256`, so a machine that had the vendored copy and now has the fetched one only keys identically if the bytes match — they do, `9e63e6e2…` both ways, so no existing user gets a ~104-second cold rescan on upgrade. And `registerFromVendoredPack` already returned `false` for an absent directory with the caller falling back to the compiled implementations, its own comment naming "a tarball packed without it" as an expected case — so audit scores identically with nothing vendored. The migration in `fp-reset` deliberately does NOT fetch: `resetHome` is synchronous and runs inside `failproofai update`, and an upgrade that blocks on github.com and fails when it is unreachable is a worse upgrade than one that finishes. The carried names stay in config, which is what the no-pack fallback reads, so a machine mid-upgrade keeps enforcing exactly what it enforced before. (#738) + +- **Setup no longer decides which policies you get.** The wizard's policy step is gone, and so is the larger offender behind it: the opening "Recommended" path skipped that question entirely and installed `RECOMMENDED_POLICIES`, fifteen hardcoded builtin names, on behalf of somebody who had not seen the list. failproofai ships no policies of its own any more — they arrive as packs, from inside this package or from anyone's GitHub release — so a wizard pre-ticking OUR set is a product decision taken for a user who cannot yet evaluate it, and not everyone wants what we would have chosen. Setup now wires the hooks and stops; choosing what they enforce is a separate act. Whatever the scope already had is read and carried through untouched, because `installHooks` runs with `replace: true` and passing anything less would switch off policies the user turned on — running setup twice must never reduce protection. `policy-presets.ts` is deleted. `customPoliciesEnabled` is now left alone in both modes rather than written from a checkbox that no longer exists, which also closes the leak where finishing setup disabled every convention policy on disk as a side effect. (#738) + +- **`policies`, `policy` and `pack` were three commands for one idea, two of them a single letter apart, and they are now one.** `failproofai policies add` takes either a policy name or a pack source, told apart by a SLASH — a policy name matches `/^[A-Za-z0-9._-]+$/`, so a slash is already illegal in one and unambiguous in the other, the same rule npm and docker use, and nobody has to discover a flag before they can install somebody else's policies. `policies remove` and `policies show ` complete it. `policy`, `pack` and `p` are translated to `policies` above every dispatch rather than rejected, so nothing anyone has typed before stops working — those spellings are printed in shipped help, in the docs, and in the release notes of every pack published so far. `pack list` split into the two questions it was conflating: bare `policies` for what is installed here, `policies show` for what a pack out there contains. (#738) + +- **`failproofai policies add` with nothing after it shows you the list instead of erroring.** It used to answer "Missing policy name" and tell you to go read a list elsewhere and come back — the command telling the user to do the work it exists for. The same objection applied to a bare `pack add`, which took the publisher's defaults and only afterwards printed what it had decided: a default is a suggestion, and a suggestion nobody saw is a decision taken on their behalf. There is now one screen showing every policy on the machine, grouped by pack and category, with the current state pre-ticked, built on the `multiSelect` the wizard already uses rather than a second picker. It refuses rather than guesses with no terminal to draw on: `multiSelect` degrades by returning its pre-checked set, which there would mean confirming exactly what is already true — a silent no-op reported as success. (#738) + +- **`failproofai publish` replaces four commands, two of which never published anything.** Installs read `releases/download//` and never touch the git tree, so `git init`, `git add`, `git commit` and `gh repo create` were all for humans reading the source — a publisher could only learn that by reading `pack-store.ts`. One command now validates the entry with the loader's own rules, writes the three assets, creates or reuses the release and attaches them. It goes over the GitHub REST API rather than `gh release create`, because our own `block-gh-pipeline` builtin matches that exact command — shipping a publish path our own guardrail blocks is not a thing to do. Two failures the manual flow let through silently are refused: a tag that does not describe the manifest version (which installs and then reports a version matching no URL), and a private repository (which publishes to nobody, since `pack add` sends no Authorization header at all, by design). `pack build` is now a spelling of `publish` with nowhere to publish to, and means the same thing. (#738) + +- **The top-level help was 152 lines — six screens at 80x24 — and is now 26.** Every flag of every command was inlined on the index, so the thing you read to find a command was the thing you read to use one, and the cost of that fell on the person who knew least. There is now one screen of what exists, grouped by where you are in the arc, and `failproofai help ` for everything else. `help ` dispatches to ` --help`, so there is exactly one copy of each command's documentation and the two spellings cannot drift. Three things that were documented nowhere reachable are now reachable: `failproofai update --help` and `failproofai migrate --help` both exited 1 with "Unexpected argument" because `SUBCOMMANDS` omitted them, and `--hook` — the entry point an agent CLI spawns on every tool call — appeared only in a module docblock and one error string, and now has `failproofai help hook`. (#738) + +- **The TUI palette is the brand's two accents and nothing else.** The design system defines exactly two — pink `#e4587d` and mint `#66d1b5` — and says so explicitly; `tui.ts` carried three, with selection and "enabled" painted in `#ff2e88`, a hotter pink in no brand token, alongside a near-duplicate `logoPink` one byte away from the real one. They are collapsed into a single brand pink, so the logomark and the prompts can no longer drift apart. A 256-colour tier is added between the two that existed: colour resolution jumped straight from 24-bit to basic ANSI, so every terminal that supports 256 colours but does not advertise `COLORTERM` — which is most of them over SSH — fell all the way back to sixteen. `NO_COLOR` and a non-TTY still emit zero escape sequences, and the sixteen-colour tier is unchanged and still usable on its own. (#738) + +- **A long policy name ate its own description, on exactly the screen this release adds.** The name column is capped at 24 and the description budget is sized against that cap — but `padEnd` pads, it does not truncate, so a longer name rendered at its true width against a budget measured for a shorter one. On an 80-column terminal `sanitize-connection-strings` and `sanitize-private-key-content` both landed on column 80: nothing wrapped, nothing looked broken, and the description was simply cut by the terminal instead of by `ellipsize`, losing the `…` that says it was cut. A third-party pack with a longer name would have wrapped outright. The name keeps its full width and the description gives up the space — a policy name is the thing you type next and half of one is useless, while prose shortens for free. (#738) + +- **`policies add` with no name answered a script with an exit code it could not act on.** The no-terminal refusal was checked *after* the no-packs branch, so a fresh machine running it from a pipe got the "here is where policies come from" screen at exit 0 — an interactive question answered with a success. It refuses first now, whether or not a pack happens to be installed: the empty state is an answer for a human at a terminal, not a status for a script. (#738) + +### Fixes + +- **A test of the new picker depended on a directory CI does not have.** `policies add core` reads the pack vendored in the package, which `bun run build` writes — and `test` and `build` are separate CI jobs, so `policy-pack/` does not exist when the tests run. Every other pack test generates it; the new one now does too, and pins `FAILPROOFAI_PACKAGE_ROOT` at what it generated rather than relying on a repo root that happens to be populated on a contributor's machine. (#738) + +- **The no-pack fallback told users to run a command that no longer does anything.** A machine carrying policy names with no pack installed still enforces them from the compiled implementations, and warns that it is doing so — but the warning said to run `failproofai update` "to move them into the pack that ships with it". Both halves stopped being true the day the package stopped carrying policies: nothing ships with it, and the migration deliberately does not fetch. It names `failproofai policies add core` now, which is the command that actually leaves the shim. Nothing had been asserting on that string; a test does now. (#738) + +- **A release tag was never checked against the version inside the pack, and this repo's own convention broke it.** `spec.tag` only ever built URLs and `version` only ever came from the manifest; the two were never compared, so a pack built `--version 1.0.0` and released under tag `v1.0.0` installed cleanly while recording a version that matched no URL. It bit immediately: `pack build` told publishers to tag `` while failproofai's own releases are tagged `v`, so a publisher following house style broke their own pack. A leading `v` is now accepted, because refusing a near-universal convention would be hostile; any other disagreement fails the install naming both values and which one to change. (#738) + +- **A tagless `policies add owner/repo` misresolved silently when the newest release was a prerelease.** Resolution reads the `releases/latest` redirect, which GitHub does not issue for draft or prerelease releases — so the install either landed on an older stable tag, quietly taking something the publisher had superseded, or got no redirect at all. The error now names the prerelease case explicitly, since it is the likeliest cause a publisher hits. It still deliberately avoids `api.github.com`: no second origin, no sixty-per-hour unauthenticated rate limit, and `FAILPROOFAI_PACK_BASE_URL` keeps pointing the whole thing at a mirror. (#738) + +- **The dashboard offered a policy-source filter that could never match anything.** `builtin` survived in the source dropdown after the builtins stopped being a source; nothing produces that value any longer, so selecting it emptied the list with no explanation. (#738) + +- **A doc comment in `pack-manifest.ts` described a safety condition that had stopped being true.** It said the reader's fail-open was defensible only while the builtins shipped compiled in and kept enforcing underneath, and that the day they became a fetched pack this must be revisited rather than inherited. That day arrived. The denying moved rather than disappeared — `pack-failclosed.ts` reads the same errors and refuses the events the missing policies declared — and the comment now says so, including why a throw must not be added here.
