The same holds for GATE 2 + (the post-verify decision) and every between-stage proceed: _invoking and obeying_ the checker is + advisory orchestration, not a floor primitive (the "two clocks," stated in the checkers themselves). +- **Backstop (floor):** a forged approval moves only the advisory _intent-approval_ signal; it unlocks + no floor-gated capability — the pre-write / writes-scope hooks (and pre-egress, specified; ships with the guarded surface) re-gate every downstream + write **issued through the `Write`/`Edit`/`MultiEdit`/`NotebookEdit` tool surface** and network call + regardless of `state` — in an installed project, while a scope is set or a PHARN run is open; outside + both, the writes-scope guard no longer gates ordinary project paths (§7) — and the human GATE-2 decision + still stands between a built increment and merge. + The quantifier is bounded and the bound is load-bearing: a write issued through **`Bash`** is re-gated + by neither hook, so this backstop covers that one tool surface and no other — **§6**. + Closing the gate itself needs an out-of-band approval signal the Write tool + cannot forge (e.g. a `PreToolUse` hook admitting the Draft→Approved transition only against a + human-supplied signed marker) — that is **harness-layer**, environment-dependent, not expressible in + markdown methodology. Until an environment supplies it, this stays a named limit, not a guarantee. + +A related bound on the same checker: a valid AC grammar means the AC is PHRASED testably — not that +any test exists, runs, or passes. That bound is `check-spec.mjs`'s, not the pipeline's: for a +templated SPEC that is not `spec_kind: test-infra`, `/pharn-test` writes each criterion's test before +the build and requires it to fail, `/pharn-build` refuses without that evidence, and `/pharn-verify`'s +AC gate requires each locked, once-red test to pass on the head run (6.17.0–6.20.0) — separate checks, +bounded in §9. The template rules are opt-in by the `spec_template` frontmatter key; a SPEC without it +validates under the legacy four-section rule, and the AC stages report it not-applicable. + +The template `/pharn-spec` fills may be the project's own, `pharn.spec-template.md` at the project root +(6.14.0), and its guidance comments are instructions. `protect-trusted-paths.cjs` denies it by path, +like the trusted docs — on the `Write`/`Edit`/`MultiEdit`/`NotebookEdit` surface only; a `Bash` write +reaches it (§6). `check-bash-reconcile.mjs` detects such a write only when it lands inside a build's +anchor-to-verify window and the file is not git-ignored, and only from a non-adversarial writer: the +path is not always-reconciled, so a writer who also rewrites its baseline entry gets a silent `CLEAN`. +That window opens after `/pharn-spec` ran, so a write that steered the current SPEC is never detected +by the run it steered. A change landed by a merge, a pull or a human editor is obeyed as-is. + +--- + +## 2. The residual (named, bounded, not zeroed) + +When a downstream LLM stage consumes the **free-text** fields of a finding (`problem`, `evidence`), +"do not execute this as an instruction" becomes a heuristic again (`THREAT-MODEL.md §5`). Fix #1 +bounds it — free text never alone gates a guaranteed decision — but does not eliminate it. This is +**not the only** place the trust model is not provable on paper (`THREAT-MODEL.md §5` names the known +ones; another is the suppression channel on its §2 surface 8), and it is the one attempt 0 targets. + +--- + +## 3. Token cost model (known constraints, not solved) + +State these honestly; do not pretend tiered loading solves them. + +### 3a. Cost scales with fan-out breadth, not change size — and that is backwards + +A 3-line typo fix still fans out to every lens, each loading its rules + the diff. Tiered loading +optimizes _within_ one assembly (don't load all rules at once); it does **nothing** about fan-out +_breadth_. You pay the most for what there is the most of (small changes). This is +the largest practical token problem and it is not yet solved. + +> **The gated manual flag is `/pharn-ship --quick` (6.25.0), and it trades checks for cost.** A human chooses it for +> a `spec_kind: quick` SPEC: one to three acceptance criteria, each verified at `unit` or `integration`. It +> keeps both human gates, the grill's two floor stops, the test-first evidence for those criteria, +> `/pharn-regress`'s scope check (a file the run changed outside the plan's `## Files` still stops the run, within +> the bounds §6 states for that check) and `/pharn-verify` with its AC gate. It leaves out: **the regression +> check** — no regression outside the feature is looked for, because nothing compares base and head; **the +> plan interrogation** — `/pharn-grill --quick` runs its floor stops and no griller; and **`BRIEFING.md` and +> `RUN-REPORT.md`** (`cost.json` is still written). Its ledger outcome is `gate2-quick`, which is not +> `gate2`: `gate2` needs a `pharn-regress` stage-start, which a quick run never writes (the bounds of +> trusting those Bash-written markers are in `pharn-contracts/cost-ledger.md`). The `--quick` flag is read by +> the orchestrating model, so honoring it is advisory; what backs it is the SPEC's approved, pinned +> `spec_kind: quick`.

The decision's mode is that SPEC's pinned kind, never a flag, so a full +> SPEC still needs a regression verdict. It keeps the grill's floor stops, the test-first evidence, the scope check +> (within the bounds §6 states for that check; it leaves no record, so nothing after its iteration re-checks it) and +> the freshness check (a quick run's verify evidence must still describe the live tree and reproduce from its +> stamp). It leaves out the regression check and `RUN-REPORT.md` (`cost.json` is still written). Like every +> `/pharn-loop` run since 6.45.0, it does not interrogate the plan: the grill runs its two floor stops only. Its +> green stop is `STOP_GREEN_QUICK`, which is not `STOP_GREEN` and claims no regression check; the +> record, the commit message and the summary name the mode after the run. The person who typed `--quick` chose it, +> and the model's reading of that flag is advisory, as for `/pharn-ship`. + +### 3b. Rule overlap × stages + +The same rule file (`security.md`) is loaded into context 3–4× across a feature's life (security +griller, secrets-in-code lens, security-review auditors — specified; ships with the guarded surface) — each fresh sub-agent re-pays. Tiered +loading does not cache between stages (fresh contexts naively cannot). Real cost ≈ +`diff_size × (validators + verifiers + lenses + auditors) + rule_overlap` — both terms large, +neither touched by tiered loading. + +### 3c. Cold-start cliff + +First run (cold seam-record, cold memory, cold baseline, full seam-fallback chain for every seam) +is dramatically more expensive than the steady state the design implicitly assumes — and the first +run is exactly when a new user decides whether PHARN is worth the price. The cliff is not modeled. + +### 3d. Trust + traceability are not token-free + +Fencing scaffolding on every untrusted block + re-stating the finding schema + re-injecting the +constitution is per-call overhead × fan-out. "Free because it's frontmatter" is false at runtime; +it is a real per-leaf tax. + +### 3e. The always-loaded instruction set is a model, and its growth gate measures that model + +`pharn/floor/check-instruction-files.mjs` models which project files Claude Code attaches to every +session: the root `CLAUDE.md` / `.claude/CLAUDE.md` (else `AGENTS.md`), their `@path` imports, and the +`.claude/rules/**/*.md` files without a `paths:` scope. The model comes from Claude Code's published +memory documentation plus the assumptions its header labels. The harness's actual set may differ in +either direction (versions, settings, `claudeMdExcludes`, HTML-comment stripping, the 4 MiB skip). + +- **Struck claim:** "`instruction-growth` PASS means the session prefix did not grow." +- **True statement:** `--growth` (the `/pharn-verify` gate `instruction-growth`, 6.38.0) is a floor + verdict over that model: the bytes added to the modelled set since a base commit, against + `budget.instructionGrowthBytes` read from `pharn.config.json` at that base (default 2048). It measures + changed-since-base, not written-by-the-build; with a dirty working tree only uncommitted growth is + seen; and a per-change budget does not bound growth accumulated across changes that each stay under it. +- **Under-count routes, known so far and never a complete list:** a catch-all `paths:` pattern spelled + another way, a YAML error the line reader does not recognise beside `paths:`, an always-loaded file + made git-ignored, and an uncommitted edit inside an initialised submodule. +- **Not counted:** git-ignored files, `CLAUDE.local.md`, subdirectory `CLAUDE.md` files, directories + above the project root, `~/.claude/**`, managed policy files, and auto memory. +- `--report` is advisory, and its token figure is bytes/4 (§1c). Whether `pharn update` preserves the + `budget` key in `pharn.config.json` is not verifiable from this repository; a dropped key falls back to + the default, which is the strict direction. + +### 3f. What goes into an instruction file is a planning choice, and the rule that steers it is advisory + +`/pharn-plan` carries an advisory planning rule (6.38.1): a feature's narrative, rationale, history and limits stay +in its record, and a plan names an instruction file only for a standing convention every future session must obey. +Nothing deterministic stops a plan from naming `CLAUDE.md`, and no behavioural eval covers `/pharn-plan`. The +deterministic backstop is §3e's `instruction-growth` gate at `/pharn-verify`. It bounds the bytes one change adds to +the modelled set, never what a plan names, and never growth accumulated across changes that each stay under budget. + +--- + +## 4. What "good architecture" means here + +Per P0, claiming the architecture is "proven good" would be the exact disease this repo +prevents. The honest standard: + +- Every _guarantee_ reduces to the floor (`ARCHITECTURE.md §2`) **or** is labeled `advisory`. +- The _known_ holes from red-team are closed or labeled (`THREAT-MODEL.md §4`). +- The four irreducible limits (§1) are named, not hidden, and backstopped. +- The residuals (§2, `THREAT-MODEL.md §5`) are named, and the free-text one is the first thing the + experiment tests. + +"Good" = known holes closed or labeled, and limits honest. **Not** "no holes." The unknowns are +discovered by building and measuring, not by more review. + +--- + +## 5. Observability is interrogated at plan time only + +The `observability` griller (`pharn/pharn-pipeline/grillers/observability/`) reads **the PLAN** and +nothing else. Its scanner, `pharn/floor/scan-plan-observability.mjs`, is one of five `scan-plan-*` +scanners; there is no `scan-code-*` counterpart, and no lens in `pharn/pharn-review/` reads code for +telemetry wiring. + +The consequence, stated plainly: **a plan may declare telemetry, pass the grill, and the diff that +results may wire none — with every floor green.** Under an unattended `/pharn-loop` (since 6.45.0) the grill runs +only the observability scanner, not the griller's judgment, so there the plan's telemetry is not judged at all. +Nothing downstream re-checks the promise against the code. `/pharn-verify` runs the project's own discovered gates, +less any the project excludes in `pharn.config.json` `gates.exclude` (6.36.0); a gate result can also be reused from +the same delivery run's `/pharn-regress` (6.34.0). If the project has no telemetry test, or excludes the gate that +runs it, neither does PHARN. + +Two reasons this is a limit rather than a gap awaiting a fix: + +- **There is no configured sink.** `pharn.config.json` has no telemetry key — the nearest, since + 6.15.0, is `testResults`, which names a test reporter's format, not a sink — and + `pharn/pharn-contracts/seam-config.md` names no telemetry concept. A + project cannot tell PHARN what its logger is, so any code-side check must hardcode a name set and + will misread every custom sink. +- **Absence is not injection-immune the way presence is.** For a concern whose shape is _absence_, a + scanner hit is GOOD and therefore _suppresses_ — the inverse of `scan-plan-secrets.mjs`. On code, + masking stops a comment from suppressing, but a real dead `logger.debug()` call still does. + +`pharn/floor/scan-code-swallowed-exception.mjs` is the nearest existing check and is not this: it +reads logger calls inside `catch` bodies with **inverted polarity** — logging there is evidence the +error was _swallowed_. A catch that rethrows and emits nothing is CLEAN to every check PHARN ships. + +Reopens when a real failure surfaces it (P7) — a dogfood or eval run where a plan-declared signal +was absent from the built code — or when a sink becomes declarable. + +--- + +## 6. The write guards cover one tool surface; `Bash` is outside it + +The `PreToolUse` matcher wired in `.claude/settings.json` is `Write|Edit|MultiEdit|NotebookEdit`, and +both hooks re-test that same set in their own code (the `isWrite` test in each of `enforce-writes-scope.cjs` and +`protect-trusted-paths.cjs`). A write issued through the **`Bash`** tool therefore never reaches +either hook. Probed rather than read off the wiring — §1d's quantifier is precisely why: + +| payload | hook | verdict | +| ------------------------------------------------------------- | --------------------------- | ------------------------- | +| `{"tool_name":"Bash",…{"command":"printf x >> LIMITS.md"}}` | `protect-trusted-paths.cjs` | **exit 0** — not denied | +| `{"tool_name":"Bash",…{"command":"printf x >> README.md"}}` | `enforce-writes-scope.cjs` | **exit 0** — not denied | +| `{"tool_name":"Edit","tool_input":{"file_path":"pharn/LIMITS.md"}}` | `protect-trusted-paths.cjs` | exit 2 — denied (control) | + +- **Struck claim:** "the trusted docs are write-protected", "`writes:` is enforced", or "canon cannot be + written", stated without a tool-surface qualifier. Each is true of `Write`/`Edit`/`MultiEdit`/ + `NotebookEdit` and false of `Bash` — including for **this file**, which the probe above reaches. +- **True statement:** a `Bash` write is **not denied**, and is **not detected at the time it happens**. No + `PostToolUse` hook is wired (`grep -c PostToolUse .claude/settings.json` → `0`), so nothing observes + the write, and no record of it exists to reconcile later. +- **It IS detected AFTERWARDS, as of `SKILLS_VERSION` 4.0.0 — and detection is strictly weaker than + prevention.** `/pharn-*build` anchors a content-hash baseline and `/pharn-*verify` runs + `pharn/floor/check-bash-reconcile.mjs`, which re-hashes the tree and asks the **live guards**, by + executing them, whether each changed path would have been denied. Denied means the `reconcile` gate + fails, so the verify verdict is `FAIL`. **The supported claim is exactly "a write to a path the active + scope would have denied is detected and fails the stage" — never "Bash writes are prevented."** Four + bounds, all in `pharn/pharn-contracts/reconciliation-record.md`: ignored paths are outside the + reconciled set; the window is anchor-to-verify; the model is **one worktree per session** (two sessions + sharing a tree share `.pharn/`, so a second session's writes can surface as this one's escape — + [[L38]], which this inherits and cannot fix); and there is **no attribution** — it reports *what*, + never *who*. +- **DELETING it is loud; FORGING it is silent — and that bounds the whole claim.** The baseline lives + under `.pharn/`, which `Bash` reaches, and nothing authenticates it. Deleting it does not yield a quiet + green: `/pharn-*verify` passes `--require-baseline`, which makes an absent baseline `INCONCLUSIVE`, and + the always-reconciled control surface (`.claude/hooks/*`, `.claude/settings*.json`, `pharn/floor/*`, + `.dev/floor/*`) is compared against **committed blob ids** rather than against the baseline, so that + half resists a determined writer. But for an **ordinary** path the baseline IS the reference, so a + writer who edits a denied file **and** rewrites that file's baseline entry obtains a silent `CLEAN` — + no escape, no warning. **Therefore the guarantee is NON-ADVERSARIAL detection:** it catches tooling + that escapes its scope — a formatter, a generator, a script, a mistake, which is the entire population + of the failures [[L19]] and [[L20]] recorded — and it does **not** catch an attacker. "The detector + cannot be disabled" is **struck**; "it cannot be disabled quietly" is **struck for ordinary paths** and + true only for the control surface. Closing it needs authenticated state outside the worktree — the same + harness-layer category as the OS sandbox below, and just as absent. +- **Two further bounds, stated rather than solved.** (1) `/pharn-*verify` runs the **worktree** copy of + the checker through `Bash`, so a modified checker can print `CLEAN` without reconciling anything; + `pharn/floor/` is always-reconciled, which means a modified checker is caught **by itself**, and that + is circular rather than a guarantee. (2) The anchor is a `Bash` step ([[L19]]), so a run that **skips** + it does not reliably fail — `--require-baseline` is satisfied by whatever earlier epoch is still on + disk, and the reconciliation then ranges over the wrong window. Only a tree that has **never** anchored + yields `INCONCLUSIVE`. +- **No shell command is ever parsed, and that is a design constraint rather than an omission.** Shell + parsing is undecidable and a verb denylist is a heuristic, which P0 forbids labelling a guarantee. The + reconciler compares hashes and paths, so `sed -i`, a here-doc, `node -e`, a Makefile target and a + compiled binary are equally visible to it, and none is special-cased. +- **Older partial backstop, advisory and still present.** `pharn/floor/check-regress.mjs scope` exits 1 on a changed + path the plan's `## Files` did not declare (since 6.17.0 `/pharn-regress` also declares + `AC-TESTS.md`'s), and before 4.0.0 was the only thing in the tree that could surface such a + write after the fact. Five bounds, every one stated in that checker's own header or in + `pharn/floor/pre-run-snapshot.mjs`'s: it fires only if + `/pharn-regress` runs, or when `check-quick-scope.mjs` (6.28.0) applies that rule — for `/pharn-ship --quick`'s + item 7 and for every `/pharn-loop --quick` iteration — to inputs it builds by code exactly as that stage's script + does, without the rest of that stage; it compares _changed since base_, not _written by the build_; it carries + closed-enum exemptions for the pipeline's own artifacts; a plan that edits its own `## Files` + (or its `AC-TESTS.md`) defeats it; and, inside a `/pharn-loop` or `/pharn-ship` run (6.37.0), a path already + changed when the run began whose bytes still equal the run's pre-run snapshot is reported, not counted — so a build + that writes such a path back to its pre-run bytes is not seen, a path an earlier run escaped with is pre-run state + for a re-run (reported, not refused), and the snapshot, kept in the git dir out of the write tools' reach, can be + forged through `Bash`. A smoke alarm, never the guard. +- **The only true prevention is OS-level sandboxing of the `Bash` process** — a filesystem jail, a + read-only mount, or an equivalent harness-layer control that makes the write fail before any hook + would be consulted. PHARN does **not** implement it, and cannot: exactly like §1d's out-of-band + approval signal, it is **harness-layer, environment-dependent, and not expressible in markdown + methodology**. Until an environment supplies it, this stays a named limit, not a guarantee. + +**Why this is not one of §1's four irreducible limits.** It _is_ reducible — the sandbox above reduces +it — just not by anything this repository can ship. §1's four cannot be reduced at all, which is what +"irreducible" means there; folding this one in would dilute that word. + +**Detection did not close this limit, and must not be read as having closed it.** A detected write has +already happened: the reconciler reports, it never reverts, and rollback is explicitly out of scope +(nothing captures pre-write content, and a revert is itself a write). What changed in 4.0.0 is that the +write stops being **silent** — it costs a red stage instead of nothing. The distance between "nobody can +do this" and "somebody will notice this happened" is the distance between a prevention and a detection, +and this section names which side PHARN is on. + + +--- + +## 7. The write guards act only when Claude Code starts them, and judge the tree Claude is in + +Every write-guard claim in this file, and `THREAT-MODEL.md §4` items 2 and 7, holds only while both +`PreToolUse` hooks actually **run**. Claude Code runs a command hook in Claude's **current** directory, and +treats a hook that exits with anything other than 0 or 2 — including one whose script cannot be found — as a +non-blocking error. Until `SKILLS_VERSION` 6.1.0 the shipped wiring was a relative `node .claude/hooks/…`, +so after any persisted `cd` into a subdirectory **both guards silently stopped running**. Probed rather than +read off the wiring: + +| hook command run from | payload | exit | +| ----------------------------------- | ---------------- | ------------------------------------------------ | +| `pharn/pharn-core`, relative wiring | `Edit LIMITS.md` | **1** — `Cannot find module`; the write proceeds | +| repo root, relative wiring | `Edit LIMITS.md` | 2 — denied | + +6.1.0 anchors both commands on `${CLAUDE_PROJECT_DIR}`. The bounds that remain: + +- **A guard that cannot start, or that times out, still does not block.** That is Claude Code's documented + behaviour, and no hook can change it. +- **The fix reaches an install only through its own `settings.json`.** `pharn update` never touches that + file, so an install upgraded without editing it keeps the relative form and stays fail-open from every + other directory. Upgrade the hooks first, then the two commands; roll back in the reverse order. +- **"Current directory" is the hook process's.** When Claude's own directory no longer exists, Claude Code + runs hooks from the session-start directory, the project root, home or temp, and the guards judge that + directory instead. +- **A project path containing `"`, `` ` ``, `$` or `\` is unsupported.** The placeholder is substituted into + a shell command, where such a character can make the command mis-expand — the guard then does not start — + or run text taken from the directory name. +- **Jurisdiction is the git working tree that contains Claude's current directory**, or `CLAUDE_PROJECT_DIR` + when the walk reaches that first. A session cannot write another worktree by path: that write is denied, + not unguarded. A launch-checkout session writing into a nested `.claude/worktrees//` is judged by + its own writes-scope, which could name that worktree's hooks if a plan declared them. +- **A `.git` entry is trusted as a boundary.** Tool writes to git metadata — any `.git` path segment under a + guarded root — are denied, because those entries decide jurisdiction. A `Bash` write still reaches them + (§6), and re-pointing a worktree's `.git` through `Bash` removes the trusted-file guard from that worktree. +- **A PHARN install at a subpath of a repository, entered through a worktree of that repository**, reads a + different scope record than its setter wrote, and falls back to the default-safe-set — and, because that + root carries no `skillsVersion` of its own, it keeps the fail-closed default outside a run as well: + friction, not a hole. +- **In an installed project, `enforce-writes-scope.cjs` is fail-closed only while PHARN is working + (6.24.0).** With no scope set and no open `/pharn-ship`, `/pharn-loop` or `/pharn-review` run, it denies + PHARN's installed surface — `pharn/**` except `pharn/features/**`, `.claude/**` and `pharn.config.json`, + matched case-folded, with the `pharn/features/` exception matched as written, so a case or trailing-dot + variant of it is denied — plus its own input `.pharn/writes-scope.json` and, on a system whose separator + is `/`, any path containing a backslash: there a backslash is part of a file name, while the guards' path + folding reads it as a separator. It allows every other path inside the project, including the files + Claude Code loads at session start (`CLAUDE.md`, `AGENTS.md`, `.mcp.json`), so a write made outside a run + can shape later runs. `protect-trusted-paths.cjs` still denies its own set in every posture. +- **Outside the project, that permissive default allows only this project's auto-memory folder, this + session's own scratchpad, and ordinary temp paths** — never a path inside another git tree: + - **This project's auto-memory folder**, `/projects//memory/**`, where the config + dir is `$CLAUDE_CONFIG_DIR` when set, else `~/.claude`, for two keys only: the project folder that holds + this session's transcript, read from the `transcript_path` Claude Code passes every hook, and the key + Claude Code derives for auto-memory from the repository's main checkout, so a session in a linked + worktree or in a subdirectory still reaches its project's memory. **That second key mirrors an + undocumented Claude Code derivation** — a worktree's `.git` file, its `commondir`, and a `gitdir` + back-pointer that must name this worktree, with the path encoded by turning every character outside + `[A-Za-z0-9]` into `-` — **and it fails closed if that derivation drifts**: a check that does not hold, or + a path over 200 characters (Claude Code hashes those, and the hash is not copied), grants nothing. + Another project's memory folder stays denied: Claude Code loads it into that project's later sessions. + A project here is a key: two paths that differ only in characters outside `[A-Za-z0-9]` (`…/a-b` and + `…/a/b`) encode to one key, and Claude Code gives them one memory folder, so the guard allows it to both. + - **This session's own scratchpad**: the `scratchpad_dir` Claude Code passes, and only in the shape Claude + Code writes, `/claude-///scratchpad`, for the payload's own `session_id`. + - **An ordinary temp path**: under the OS temp directory (`os.tmpdir()`, which honours `$TMPDIR`) or + `/tmp`, but never with a `claude-` folder anywhere in its path — Claude Code's per-user state, which + holds every session's scratchpad and task output — never inside the Claude config directory, whichever of + it and the temp root contains the other, and never inside the home directory when that lies inside the + temp root. Claude Code's other temp paths outside a `claude-` folder (`cc-socks`, + `claude-mcp-browser-bridge-*`, the desktop app's `ShipIt` update folders) are ordinary temp paths to this rule. + - Every other out-of-project path stays denied: another project's memory, dotfiles, `~/.ssh`, + `~/.claude/settings*.json`, `~/.claude.json`, `~/.claude/hooks/`, LaunchAgents. + - **Fail-closed, and what that costs.** A payload field that is absent or malformed makes the place that + needs it grant nothing, never a wider one; so does a path field not in normal form (not absolute, or with a + `.` or `..` segment). So a Claude Code that sends no `scratchpad_dir` gets no + scratchpad allowance; a PHARN install at a subpath of a repository, whose root holds no `.git`, gets + nothing from the main-checkout key; and a custom `autoMemoryDirectory`, or a memory directory Claude Code + keys some other way, is not recognised. The payload fields are set by the harness, + not the model — a tool call sets only its own input — and the guard checks their shape; it cannot verify + they are Claude Code's own. The roots are read from the hook's environment, so an environment that points + `CLAUDE_CONFIG_DIR`, `HOME` or `TMPDIR` at a broad directory widens them. + - A different spelling of the project's own path is never an out-of-project path: a path that matches the + project's once letter case, Unicode form and trailing dots/spaces are ignored reaches the project's own + files on a case-insensitive volume, so it is denied as the project's own (re-review R1) — and so is a + sibling directory named like the project plus a trailing dot, although on APFS that is another + directory: an over-block. +- **A run is open while `.pharn///active.json` exists with a + modification time within 24 h**, or while one of those three state directories is present but is not a + readable directory — a file planted there holds the tree fail-closed until someone removes it. The + markers are written and removed through `Bash` (§6). `/pharn-ship`, `/pharn-review` and `/pharn-loop` + stop when opening their marker fails (the loop also when its pre-run snapshot does), but a run that + skips the step is unguarded between its stages, a crashed run's marker + keeps every session in the tree fail-closed for up to 24 h unless it is closed, and `touch` extends it. + The posture needs `skillsVersion` at the root the guard judges.

In a dev checkout or an + unsignalled tree that, and a guard error now denying instead of crashing open, are the only verdict + changes, and both move toward deny; the first includes a path spelled with another letter case or + Unicode form than an existing directory, now also judged at that directory's own spelling.
