It accepts a Pathbase URL, an `owner/repo/slug` shorthand, a local toolpath JSON file, or a cache id; resolves it (caching URL fetches under `~/.toolpath/documents/` unless `--no-cache`); validates that the document is a single agent-bearing `Path`; then opens an `fzf` harness picker (skipped with `--harness X`). The picker pre-selects the source harness inferred from `path.meta.source` (`claude-code`/`gemini-cli`/`codex`/`opencode`/`pi`) when it's installed. After picking, `path resume` projects the session into the harness's on-disk layout under the chosen working directory (default: shell cwd; override with `-C, --cwd P`) and `execvp`'s the harness's resume command (`claude -r ` / `gemini --resume ` / `codex resume ` / `opencode --session ` / `pi --session `). On Windows it spawns and waits, propagating the exit code. The exec is mockable via `cmd_resume::ExecStrategy` — production uses `RealExec`; integration tests use `RecordingExec` to capture the recipe without launching a real harness. - `path query` does not load the whole cache into memory when it can avoid it. `crates/path-cli/src/query/plan.rs` parses the jaq filter into jaq's own AST (`jaq_core::load::parse::Term`) and classifies it into a `Plan`: `PerFileStream` (`.[] | g` element-wise work — run per document, print as you go), `Decompose { reduce }` (algebraic aggregations — run the whole filter per file, concatenate the per-file outputs, then run a derived combine: `map`→`add` (array concat), top-N `sort_by(k)|.[:N]`→`add | sort_by(k)|.[:N]`, `length`→`add` over exact integer counts), or `Slurp` (the always-correct whole-array fallback). Recognition is conservative — a non-distributive prefix like `unique`/`group_by` slurps, and so do scalar `add` (float sums re-associate across per-file partials), `min`/`max` (`[] | min == null` poisons the merge), and any unrecognized tail — so **the planner never changes an answer** — `crates/path-cli/src/query/filter.rs` tests assert streamed output equals slurp byte-for-byte. `filter::execute` compiles the filter once (jaq's compiled `Filter` is fully owned, so it's reused across files) and drives the plan; `mod.rs::stream_files` yields one document's wrapped steps at a time. `TOOLPATH_QUERY_EXPLAIN=1` prints the chosen plan to stderr. No user-facing flag — it's automatic. Tie-break caveat: a streamed top-N matches slurp's *ranking*, but boundary ties may resolve to different specific rows. - Cache sync: `path p cache sync [types…]` (`crates/path-cli/src/artifact.rs`: `ArtifactType` + `ArtifactRef` + the stamp helpers; `sync/engine.rs`: manifest + ingestion loop, no UI — it reports through a `SyncObserver` trait, `&mut ()` for a silent sync; `sync/sources.rs`: an `ArtifactSource` trait — enumerate / stamp / derive — with one impl per provider, so the engine never matches on artifact type; `cmd_cache.rs`: the stderr progress line + summary) incrementally ingests artifacts into the cache — no args syncs every artifact type. Change detection is **stat-level**: each artifact is enumerated as an `ArtifactRef` whose fingerprint is the source file's mtime + size (claude: the *whole session chain* — max segment mtime + summed segment sizes via `claude_chain_stamp`, because Claude Code rotates to a new file on continuation while the chain keeps its oldest segment's id, so appends land in the newest file, not the head; the chain comes from the same cached index `list_conversations` builds; codex: rollout file, id from the stem's trailing UUID; pi: session file, id from a one-line header peek; copilot: `session-state//events.jsonl`, pure read-dir + stat) or the DB row's updated-at (opencode: header-only `SELECT time_updated`; cursor: composer headers' `lastUpdatedAt`, bubble-less drafts skipped, workspace-less composers *included* unlike `share`). Gemini enumerates via `PathResolver::list_session_entries` (`toolpath-gemini` 0.6.1), whose identity peek is bounded to the first 4 KiB of a main file. Deciding "nothing changed" reads no session bodies — a no-op sync is milliseconds. Changed/new artifacts derive through the same provider managers (each source calls the `derive_*_session_with` helpers in `derive.rs`). Manifest at `~/.toolpath/manifest.json`: artifact type → artifact id → `{path?, cache_id, modified?, size?, synced_at}`; atomic temp+rename writes, `0600`, checkpointed every 10 writes (interruption-safe: a killed run keeps nearly everything it derived, and derives run newest-first so partial progress covers the sessions that matter most); writers serialize on an advisory lock (`manifest.json.lock`) and every write is a locked read-merge-save — checkpoints merge only the records the run wrote — so concurrent invocations (query auto-syncs, imports) union their records instead of clobbering each other. Pending work reports progress on stderr (`\r`-updating ` done/total` on a TTY, a plain line every 25 items otherwise; no-op syncs stay silent). Sync always writes the cache with force — refresh semantics — and never deletes: artifacts removed upstream keep their cache docs and manifest records (archive, not mirror). Derivation failures warn and tally, they don't abort. A record's `cache_id` is *optional*: a record without one is "known, not materialized" — created when `p cache rm` evicts a doc (rm downgrades the record; the next sync re-materializes it, and sync also verifies the doc file actually exists before skipping, so even out-of-band deletions self-heal). Claude derives leave `DeriveConfig.project_path` unset so `path.base` comes from the session's own recorded cwd rather than the lossy slug. `path query` runs this sync implicitly before reading, scoped to its flags (`--source X` → that type; `--id`s → their prefixes; bare query → all types; `--input`-only → none), quiet unless something was ingested, degrading to the cache as-is if sync fails; `--no-sync` opts out. `p import` and `share` record what they write: every session derive carries a provenance `ArtifactRef` (stamped *before* the source is read, in `DerivedDoc.provenance`), and the cache-write sites call `sync::record_artifact` so the next sync sees those artifacts as unchanged instead of re-deriving them. Every import flow — explicit `--session`, picker multi-select, `--all`, and the most-recent fallbacks — loops the per-session helpers, so every session write is recorded; there is no bulk `derive_project` path in the CLI anymore, and `p import pi --all` now emits one Path per session like every other provider (it used to emit a single combined Graph). `--no-cache` paths record nothing: the manifest describes the cache. +- Redaction workflow (`toolpath-redact` + `path p redact`): plan-then-apply, not a single opaque pass. `surfaces()` enumerates every string field a credential could hide in. `plan::generate()` runs detectors over those surfaces, producing a reviewable `Plan` with stable ids and elided context. `apply()` consumes the plan and rewrites the document. The plan can be decided by predicate, by picker, or by hand-editing JSON. In-place redaction (`--input `) rewrites the cache entry; re-deriving from the source (`p cache sync`, including the implicit sync `path query` runs) replays the stored `RedactionPolicy`, so turns added after a resume are redacted too. A detector is a trait (`Detector`), not a function, so its implementation is swappable: a `FixedDetector` for tests, the built-in rule-based detector by default, and a harness-time hook for pre-training redaction. Detection is the part of this problem where precision is worst and the field moves fastest, so it sits behind the plug point; traversal (fields, pointers, surfaces) is stable and reused by all detectors. **Replay is not airtight**: `p import --force`, `share`, `p cache rm`, and a concurrent redact-during-sync each write cleartext over a redacted cache entry; `hash` is not idempotent (bare 6-hex has no envelope, so each pass re-redacts the last one's output); and `Graph.meta` is never scanned at all, because `cmd_redact` iterates `doc.paths` and a graph's own title, intent, refs and actors are unreachable from its members. Documented in `docs/superpowers/notes/2026-07-30-redaction-known-gaps.md`; none is fixed, because closing them means changing shipped behavior. - Claude Code plugin: `.claude-plugin/marketplace.json` (marketplace `toolpath`) + `plugins/claude-code/` (plugin `path`, so commands are `/path:share` and `/path:query`). The plugin does **not** commit binaries — both commands invoke the CLI through `plugins/claude-code/scripts/ensure-path.sh`, which prefers an existing Toolpath `path` on PATH (identity-checked via `--help`), else `~/.local/bin/path`, else `~/.toolpath/bin/path`, else downloads the latest GitHub release (sha256-verified, same logic as `scripts/install.sh`) and installs globally to `~/.local/bin` — falling back to `~/.toolpath/bin` when a foreign binary named `path` claims the name. Two hard-won constraints baked into the command docs: slash-command inline `!` context commands and model-issued Bash must not contain `$PWD`/variables (Claude Code's permission checker rejects commands it can't statically analyze — hence the `sessions` and `current-session` helper modes, the latter reading `$CLAUDE_CODE_SESSION_ID` so no-arg `/path:share` shares exactly the running session), and `--project` must always be an absolute path (path-cli does not canonicalize relative `--project` values; `.` silently matches nothing). Tests: `scripts/test-plugin.sh` (manifest consistency + offline bootstrap tests against a stubbed curl/release), wired in as the `plugin` quality gate; plugin shell scripts are shellchecked. Dev loop: `claude --plugin-dir ./plugins/claude-code`. Future harness integrations go under `plugins//` (only Claude Code plugins are marketplace entries; other harnesses distribute their own way). Version bumps: keep `plugins/claude-code/.claude-plugin/plugin.json` and the matching entry in `.claude-plugin/marketplace.json` in lockstep (test-plugin.sh asserts this); the binary is unpinned (latest release) with `MIN_VERSION` in ensure-path.sh naming the oldest CLI the command docs support. - `ArtifactType` (`crates/path-cli/src/artifact.rs`) is the general enum naming artifact sources — the seven agent harnesses (incl. copilot) plus `Git` (8 variants). Git artifacts are *recorded* in the manifest by `p import git` (id `-`, `path` = the repo directory) but never *discovered* — there is no machine-wide registry of repos — so sync reports them and leaves them alone. Github and pathbase are deliberately not artifact types: they are remote services, not local artifact sources, and their imports stay out of the manifest. It derives `clap::ValueEnum` and is used by `p cache sync` types, the sync manifest keys, `ArtifactRow.artifact_type`, and `cmd_import`'s cache-id prefixes (`name()` is both the manifest key and the `make_id` source string). The deliberately parallel `Harness` enum (`crates/path-cli/src/harness.rs`, alongside `HarnessBundle`) names the seven agent *runtimes* — things sessions can be shared from and resumed into — and is what `share`/`resume` `--harness` take, so future non-harness artifact types stay unrepresentable there (you can't resume into a git repo). `Harness::artifact_type()` maps into the general enum; `ArtifactType::harness()` is the partial inverse. Keep new code on `ArtifactType` unless it's genuinely harness-only. diff --git a/Cargo.lock b/Cargo.lock index d9b355b7..e55239ac 100644 --- a/Cargo.lock +++ b/Cargo.lock @@ -775,6 +775,15 @@ version

Read this before assuming a redacted document stays redacted. + +The invariant all of these violate is the one Task 10 exists to protect: +`sync::engine::is_unchanged` decides re-derivation from source mtime and +size and never inspects the document, so anything that re-derives and +writes without replaying the stored `RedactionPolicy` publishes the +cleartext it was hiding. + +## 1. `p import --force` and `share` overwrite a redacted cache entry + +`cmd_import.rs` and `cmd_share.rs` call `write_cached` with the raw +derivation and no replay, then call `sync::record_artifact`, which +deliberately preserves the stored policy while restamping `modified` and +`size` from the fresh provenance. `is_unchanged` therefore returns true +on every later sync and the cleartext is never repaired. The manifest +ends up asserting a policy that is not in force. + +Reproduce: `path p redact -i claude-sess-1`, then +`path p import claude --project P --session sess-1 --force`. + +## 2. `p cache rm` un-redacts on the next sync + +`evict_cache_id` clears the record's policy and `run_rm` deletes the key. +The record keeps its stamps but loses `cache_id`, so the next in-scope +sync re-derives with no policy and recreates the document in cleartext. +`path query` triggers that sync implicitly, so no explicit sync is +needed. + +Keeping the key and the policy would be the fix. A policy whose key is +gone can only fail forever, but the key is 32 bytes and its whole purpose +is fingerprint stability across re-redactions of that one document. + +Related: `run_rm` removes the key named by the *cache id*, not by +`policy.key_id`. Nothing enforces that those are equal, so a policy with +a different `key_id` means `rm` deletes another document's key. + +## 3. A policy recorded mid-sync is clobbered + +`sync_bundle` loads the manifest once for the whole run and +`flush_writes` merges with `BTreeMap::extend`, which replaces whole +records. Redacting in one shell while `path query` syncs in another loses +both the document and the policy. `record_artifact` already handles the +same aliasing correctly, so the two writers disagree. + +## 4. An empty `detectors` list replays as a silent no-op + +`build_detectors` returns an empty `DetectorSet` for `&[]`, so +`generate_checked` finds nothing, `apply` early-returns byte-identically, +and the run reports the document as re-redacted. The manifest is +user-editable JSON, so this is reachable without a code bug. + +## 5. An unparseable `redaction` value takes down the whole manifest + +`SyncRecord.redaction` deserializes strictly. `#[serde(default)]` covers a +missing key, not a malformed value, so one bad policy makes the entire +manifest fail to load for every artifact type. The error hint then tells +the user to delete the manifest, which discards every stored policy and +un-redacts everything on the next sync. + +Version skew is enough to trigger it: `Transform` is a plain string enum +with no unknown-variant fallback. + +## 6. `hash` is not idempotent + +`internal::marker_re` recognises `[REDACTED:…]`, runs of `█`, and +`head…tail`, and any finding whose span intersects one is dropped before +scoring. That makes `marker`, `remove`, `mask`, and `partial` reach a +fixed point. + +`Transform::Hash` emits bare 6 hex characters, which no scan can +distinguish from a fresh credential. Each pass re-redacts the previous +pass's output, rotating the fingerprint and appending an audit entry. It +matters in production because sync replays `apply` on every re-derive of +a redacted session, so a `hash`-mode redaction drifts on every +`p cache sync`. + +Pinned by `apply::tests::idempotent_across_all_transforms`, which asserts +the instability so it cannot change unnoticed. Fixing it needs an +envelope format for hashed values, which is a design decision nobody has +made. + +## 7. `share` uploads the un-redacted derivation + +Redacting a document does not affect what `share` sends to Pathbase: the +cached copy is redacted and the uploaded copy is not. This one is +arguably as specified, since the plan's non-goals say share gains no scan +and no automatic redaction. Replaying an already-approved policy for that +exact document is not obviously either of those, so it is recorded here +as a decision rather than a defect. diff --git a/docs/superpowers/plans/2026-07-30-path-redact-command.md b/docs/superpowers/plans/2026-07-30-path-redact-command.md new file mode 100644 index 00000000..38414835 --- /dev/null +++ b/docs/superpowers/plans/2026-07-30-path-redact-command.md @@ -0,0 +1,1756 @@ +# `path p redact` Implementation Plan + +> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task.

Sharing such a +document publishes them. + +## Why this is a post-generation pass + +Three other places were considered and rejected. + +**At write time, via harness hooks.** Not possible. Claude Code's `PreToolUse` +`updatedInput` changes what executes, and `PostToolUse` `updatedToolOutput` +changes what the model sees next, but neither changes what is persisted. A +controlled experiment (`~/Workspace/scripts/claude-hook-redaction-experiment.sh`) +confirmed both canaries survive to disk: the assistant record keeps the +pre-rewrite command, and the hook's replacement output is *appended* as an extra +record rather than substituted. Hooks can block a call outright; they cannot +scrub one that runs. + +**At derive time, inside `toolpath_convo::derive_path`.** Wrong layer. All seven +conversation providers and every round-trip fidelity test run through that +function, and those tests assert exact text equality against the *original* +conversation (`crates/path-cli/tests/roundtrip.rs:89`, `cross_harness_matrix.rs`). +A redactor there breaks them by construction, and it would make the local cache +lossy, which `path resume` depends on it not being. + +**At egress, inside `cmd_export::run_pathbase_inner`.** This was the earlier +proposal. It is the only unbypassable point, which is its appeal, but it couples +redaction to one destination and makes it implicit. A document is a document; +whatever is unsafe to upload is also unsafe to paste into an issue, mail to a +colleague, or commit. Redaction belongs to the document, not to one of its exits. + +A post-generation `Path -> Path` pass is explicit, destination-agnostic, +composable in a pipeline, and testable in isolation. + +## Non-goals + +- **`path share` does not scan, warn, or redact.** Redaction is a step the user + runs. The consequence is accepted deliberately: an un-redacted upload is one + forgotten command away. Revisit if that turns out to bite. +- **No live credential verification.** Validating a candidate against its issuing + provider sends secret material off the machine, including false positives that + may be someone else's real credential. That is the failure this tool exists to + prevent. +- **Not a history scrubber.** Redacting a shared copy does not un-leak a + credential that was already exposed. Rotation is still mandatory. + +## The model + +`redact` is an endomorphism over a document: + +```rust +pub fn redact(path: &mut Path, cfg: &RedactConfig) -> RedactReport; +``` + +It is deliberately **not** implemented as `extract_conversation` -> redact the IR +-> `derive_path`. That round-trip is lossy, and a redactor whose contract is +"change only what I redact" cannot be built on a lossy transform. + +The proof is concrete. `toolpath_convo::derive` writes `extra["edits"]`, the raw +MultiEdit old/new array, at `derive.rs:607`. `extract.rs` never reads that key, +and `FileMutation` has no field to hold it. More generally there is **no `extra` +escape hatch on any toolpath-convo IR type**: `Turn` and `FileMutation` are +closed structs, so every provider-specific key outside their typed fields is +dropped on the way through. Round-tripping a document to redact it would silently +delete data that was never a secret. + +So the pass walks and mutates the `Path` in place, leaving untouched everything +it does not replace. + +## Where the code lives + +A new satellite crate, **`toolpath-redact`**, depending on `toolpath` (types) and +`toolpath-convo` (the conversation field map). + +The repo's satellite crates each do one thing to a `Path`: `toolpath-dot` renders +it, `toolpath-md` renders it, `toolpath-redact` transforms it. That is the +existing shape. + +It does not go in `toolpath` core, which everything depends on and which should +not acquire a regex engine and a vendored ruleset. It does not go in +`toolpath-convo` either, whose dependency list today is `serde`, `chrono`, +`similar`, `thiserror`. Adding detection machinery there would push it onto every +consumer of the conversation IR, including the seven provider crates that have no +use for it. + +Cost, per the checklist in `CLAUDE.md`: a new crate means updates to the +workspace `members` and `[workspace.dependencies]`, `site/_data/crates.json`, +`site/pages/crates.md`, `README.md`, the `ALL_CRATES` array and publish tier in +`scripts/release.sh`, and a crate README wired into `lib.rs`. Tier 2, alongside +`toolpath-dot` and `toolpath-md`. + +## The field map + +This is the part that makes a schema-aware redactor better than a blind string +walk, and it is why the conversation knowledge matters. The pass dispatches on +`structural.change_type` and treats each field as what it actually is. + +| Change type | Field | Treatment | +|---|---|---| +| `conversation.append` | `extra["text"]`, `extra["thinking"]` | prose; span replacement | +| | `extra["tool_uses"][].input` | provider JSON; recurse to string leaves | +| | `extra["tool_uses"][].result.content` | tool output; prose treatment | +| | `extra["delegations"][]` | recursive sub-conversation; re-enter the map | +| | `extra["environment"]` | structured; `working_dir` only | +| `file.write` | `ArtifactChange.raw` | unified diff; line-count-preserving only | +| | `extra["before"]`, `extra["after"]` | whole-file content; span replacement | +| | `extra["edits"][]` | old/new pairs; both sides | +| `conversation.event` | `extra` (whole) | opaque provider payload; blind leaf walk. **The one place a blind walk is correct.** | +| any | artifact key (map key) | file path or URI; redact URI userinfo only | +| `path.meta` | `extra["vcs_remote"]` | URI; redact userinfo only | +| `path.base` | `uri` | URI; redact userinfo only | + +Two rules fall out of this table. + +**Redact the capture group, not the match.** A connection string becomes +`postgres://svc_user:[REDACTED:db-uri-password:a3c829]@db.internal:5432/prod`, +not an opaque blob. The PEM armor lines survive, the body goes. `Bearer ` stays, +the token goes. This is what keeps a redacted document readable and resumable. + +**Diffs are line-count-preserving.** A hunk header `@@ -a,b +c,d @@` declares +line counts, so replacement inside a line is safe and anything that adds or +removes lines is not. A 25-line PEM block cannot collapse to one marker. Parse +with `diffy` rather than regexing raw patch text. + +### Why the map is wider than tool input and output + +Tool I/O is the biggest surface but not the whole one. Classifying the 120 +high-confidence hits from the local census by what kind of field held them: + +| Surface | Hits | Share | +|---|---:|---:| +| Tool results and output | 60 | 50% | +| Tool inputs | 19 | 16% | +| Plain prompt and message text | 36 | 30% | +| Diff lines | 3 | 2% | +| Base64 attachment blobs | 2 | 2% | + +Scanning only tool inputs and outputs would cover two thirds of the surface and +miss the third that is a human pasting a credential into a prompt, or an +assistant quoting one back in prose. In the raw JSONL that third lives at +`$.content`, `$.message.content`, `$.message.content[].text` and `$.lastPrompt`, +and in a derived document it lands in `extra["text"]`. It has to be in the map. + +The diff row is small in count and large in consequence: those hits are in +`old_string`/`oldString`/`originalFile`, which capture pre-edit content. Using +the Edit tool to *remove* a secret from a file writes that secret permanently +into the session log. The remediation creates the durable record, so the field +that records what was removed is exactly the field that must be redacted. + +For documents whose `meta.kind` is not `agent-coding-session`, the map degrades +to the generic rows (artifact keys, `base.uri`, `meta.extra`) plus a blind leaf +walk of `structural.extra`. Git and GitHub derived paths get correct, if less +precise, treatment for free. + +## The redactor abstraction + +The pass owns traversal, the field map, transformation, and the audit record. +**What it does not own is detection.** That is a plug point, so the same command +can drive a built-in regex engine, an external scanner, or a semantic matcher +that does not exist yet. + +The split matters because detection is where the field moves fastest and where +the trade-offs are least settled (see the base rates: best open-source precision +is 0.46). Traversal and provenance are stable; detectors are not. Pinning the +former and swapping the latter is the whole point. + +### The contract + +Detectors take **strings plus context**, never toolpath types. That is a +deliberate constraint, and it buys two things: detectors are testable without +constructing a `Path`, and the same implementations can later be driven from a +pre-tool-use hook path without touching this layer. Keeping harness-time +redaction possible is a non-goal for now, but the seam is placed so it stays +possible. + +```rust +/// What the host hands a detector: one field's full value, plus enough +/// context to judge it. +pub struct Candidate<'a> { + /// The string to examine.

Tests get a +`FixedDetector` that returns canned spans, the same way `RecordingExec` stands +in for a real harness. + +### Transformation is also pluggable, with a safe default + +An external tool that wants to supply the replacement text as well as find the +span implements the second trait. Most will not. + +```rust +pub trait Transformer: Send + Sync { + fn id(&self) -> &'static str; + fn replace(&self, f: &Finding, value: &str, fp: &Fingerprint) -> String; +} +``` + +Default is `MarkerTransformer`, which emits `[REDACTED::]`. The host +always computes the fingerprint and always writes the audit record, whatever the +transformer returns - those are policy, not plugin territory. + +### Bundled implementations + +| Detector | `id()` | How it runs | +|---|---|---| +| Built-in regex engine | `internal` | In-process. Vendored `gitleaks.toml`, aho-corasick prefilter, checksum validation. The default. | +| External binary | `exec:` | Subprocess, JSON in and JSON out (below). Covers gitleaks, kingfisher, and anything else with a CLI. | +| Rust crate | `keyhog` | In-process behind a feature flag. `keyhog-scanner` is the one crates.io-consumable engine. | +| Semantic | `semantic` | Not in v1. Slots in as another impl with no change to this layer. | +| Manual map | `manual` | Reads an explicit list of values or pointers. No inference. | + +The subprocess protocol keeps the boundary honest: one JSON object per +candidate on stdin, one array of findings on stdout. + +```json +{"text": "...", "shape": "tool_output", "at": "/change/...", "ctx": {"tool_name": "Bash"}} +``` +```json +[{"span": [42, 62], "rule": "aws-access-key-id", "score": 0.99}] +``` + +A detector that returns overlapping, out-of-order, or non-char-boundary spans is +normalised by the host rather than trusted, because a third-party scanner is not +part of this codebase's test suite. + +## Dry run, and the plan file + +The command is plan-then-apply, like `terraform plan` / `apply`. A dry run +produces a **redaction plan**: a reviewable, editable JSON artifact that is also +the exact input to the apply step. Nothing is redacted without one, even when it +is generated implicitly. + +### The dry run surfaces everything it looked at, not just what it found + +This is the part that matters most and the part most tools get wrong. A report +listing only findings answers "what did you find" but not "**what did you even +look at**" - and the second question is the one a user needs in order to trust +the first. A surface with zero findings is information: it says the pass reached +that field and the detectors were silent, which is different from the pass never +having visited it. + +So the plan carries two lists. `surfaces` is every field the map named, whether +or not anything fired. `findings` is what fired. + +```json +{ + "v": 1, + "document": "claude-abc123", + "generated": "2026-07-30T18:04:11Z", + "detectors": ["internal"], + "defaults": { "transform": "marker", "threshold": 0.8 }, + "surfaces": [ + { "step": "turn-0f3a", "at": "/change/claude:~1~1sess-abc/structural/extra/text", + "shape": "prose", "bytes": 412, "findings": 0 }, + { "step": "turn-0f3a", "at": "/change/claude:~1~1sess-abc/structural/extra/tool_uses/0/result/content", + "shape": "tool_output", "bytes": 4211, "findings": 2 }, + { "step": "turn-9c21", "at": "/change/src~1config.rs/raw", + "shape": "unified_diff", "bytes": 880, "findings": 1 } + ], + "findings": [ + { "id": "f01", "step": "turn-0f3a", + "at": "/change/claude:~1~1sess-abc/structural/extra/tool_uses/0/result/content", + "rule": "aws-access-key-id", "span": [1042, 1062], "score": 0.99, + "detector": "internal", "shape": "tool_output", + "context": "export AWS_ACCESS_KEY_ID= && aws s3 ls", + "action": "redact", "transform": "marker" } + ] +} +``` + +`context` elides the match by default - it shows the surrounding line with the +value replaced by its rule name, and **not** the value's length. A plan file is +a local artifact but it is exactly the kind of thing that gets pasted into a +ticket, so it does not carry material by default. `--reveal` includes the real +values for cases where you genuinely cannot decide without seeing them; it +writes `0600` and prints a warning. + +### Deciding: bulk, then individual + +Every finding carries an `action` (`redact` or `skip`) and an optional +`transform` override. Three ways to set them, and they compose in this order: + +**1. Bulk, by predicate.** Repeatable, evaluated in order, last match wins: + +``` +--accept 'rule=aws-access-key-id' # every AWS key +--accept 'score>=0.95' # everything the detector is sure about +--accept 'shape=unified_diff' # everything in a diff +--reject 'rule=generic-assignment' # the noisy heuristic, wholesale +--accept 'step=turn-0f3a' # one turn entirely +--mode-for 'rule=us-social-security-number:mask' +``` + +Predicate fields are `rule`, `shape`, `step`, `detector`, `at` (prefix match) and +`score` (with `>=`, `>`, `<=`, `<`, `=`). No expression language beyond that - a +DSL here would be a liability. + +**2. Individual, interactively.** `--interactive` opens the picker the repo +already ships (`fuzzy::pick` with `multi: true`, external `fzf` or the embedded +skim fallback), one row per finding, TAB to toggle, preview pane showing the +elided context. This is the same UX as `p import`'s session picker, so it needs +no new interaction vocabulary. + +``` + rule score step context +> aws-access-key-id 0.99 turn-0f3a export AWS_ACCESS_KEY_ID=<…> && aws s3 ls + db-uri-password 0.97 turn-9c21 DATABASE_URL=postgres://svc:<…>@db.internal + generic-assignment 0.42 turn-0f3a deploy_token = "<…>" # ops pasted this +``` + +**3. Individual, by hand.** The plan is JSON. Edit `action` and `transform`, +save, apply. This is the escape hatch that makes the other two optional, and it +is why the plan is a file rather than an interactive-only flow. + +### Apply + +``` +path p redact --input claude-abc123 --plan plan.json --output clean.json +``` + +Apply re-derives the surfaces from the input document and **verifies the plan +still matches** before touching anything: same document id, same step ids, same +spans at the recorded offsets. A plan generated against a different document, or +against one that has since changed, is refused rather than applied approximately. + +Without `--plan`, apply generates one internally from the flags and runs it, so +the one-liner still works: + +``` +path p redact --input claude-abc123 --accept 'score>=0.9' --output clean.json +``` + +## Selection modes + +What gets replaced is a separate axis from what gets found. + +```rust +pub enum Selection { + /// Run the detector set; replace at or above the threshold, report below it. + Auto { threshold: f32 }, + /// Detect nothing. Replace only what a previous pass already recorded in + /// meta.redaction as flagged. + Flagged, + /// Replace exactly what an explicit mapping names. No inference. + Manual(ManualMap), +} +``` + +`Auto` is the default. `Flagged` exists because the honest answer to a noisy +heuristic is to surface it and let a human decide: run once to get the report, +review, then run again to apply what you accepted. `Manual` covers the case the +detectors will always miss - a bare unstructured password that only the user +knows is a password - and is the escape hatch that keeps the tool useful when +detection fails. + +Future modes slot in here without touching the traversal or the record. + +## Detection in the built-in redactor + +Everything below describes the `internal` detector specifically. Another +implementation is free to work differently; the contract above is what the host +relies on. + +One scored pass, not two tiers. High-confidence formats clear the threshold +alone; a bare high-entropy value clears it only with a nearby hotword. + +1. **Keyword prefilter.** `aho-corasick` over the rules' literal keywords, run + before any regex. 221 of gitleaks' 222 rules carry keywords, which is what + makes a large ruleset affordable per string leaf. +2. **Structured rules.** Vendor `gitleaks.toml` (MIT, 222 rules). Verified: zero + lookarounds, zero backreferences, one named group, so the entire ruleset + compiles under the pure-Rust `regex` crate with no `fancy-regex` fallback. + Order alternations longest-first, because Rust `regex` is leftmost-first with + no leftmost-longest option. +3. **Entropy as a filter, never a detector.** Gate an already-structurally-matched + candidate. A 47-character random credential and the phrase + `ThisIsAReallyLongString` score within 0.03 bits of each other, so entropy + alone cannot separate them. +4. **Hotword proximity adjustment.** A secret-ish name within ~50 characters + (Macie's default `maximumMatchDistance`) raises the score. This is the + principled form of the `NAME=value` heuristic, which measured 55% suppressible + noise on the local corpus and is not safe to auto-replace on its own. +5. **Checksum validation** where the format defines one. GitHub PATs are CRC32 -> + base62 -> last 6 characters. Offline, free, and it kills the dummy-key false + positive that entropy cannot. + +Findings at or above the replace threshold are replaced. Findings below it are +**reported but not touched**, and `--include-heuristic` opts into replacing them. + +Overlap resolution, adopted from Presidio: identical spans, higher score wins; +nested spans, the container wins regardless of score; adjacent same-type spans +separated only by whitespace, merge. Tie-break on rule id so output is +reproducible. + +## Transforms + +Default is a typed marker: + +``` +[REDACTED:aws-access-key-id:a3c829] +``` + +The rule id says what kind of thing was there, which is the part with analytical +value. The fingerprint is a keyed hash, so the same secret maps to the same token +throughout the document and a reader can still see that one key recurs across +twelve steps. + +**Key derivation.** Per-document random salt by default: within-document +coreference works, cross-document correlation does not. An optional `--key-file` +gives stable fingerprints across documents for anyone who wants rotation triage +across sessions. Never a bare unkeyed hash; a hash of a low-entropy secret is a +dictionary attack away from the secret, and the EDPB pseudonymisation guidance is +explicit that the transformation must involve a secret with sufficient entropy. + +### The full set + +Five transforms ship. `marker` is the default and the recommendation; the rest +are available because the right answer is sometimes situational, and refusing to +offer them just pushes people to hand-edit documents, which is worse. + +| id | output | length | what it leaks | +|---|---|---|---| +| `marker` | `[REDACTED:aws-access-key-id:a3c829]` | no | the *type*, plus a correlation handle. Both by design. | +| `remove` | *(empty)* | no | nothing. Also destroys the surrounding structure's readability. | +| `hash` | `a3c829` | no | a correlation handle only. No type, so the reader loses the "what was here". | +| `mask` | `████████████████████` | **yes** | the exact length. | +| `partial` | `AKIA…MPLE` | yes | the provider, the format, and 8 characters of material. | + +The bottom two rows are real disclosures, not stylistic preferences. A preserved +prefix identifies the provider, which is targeting information, and pins the +format and therefore the exact brute-force search space. A length-preserving mask +publishes the length, which for a fixed-format credential narrows the space +further. They are offered, they are documented, and they are not the default. + +Transform is settable globally and **per rule**, which is what makes the choice +useful rather than a blunt instrument: + +``` +--mode marker --mode-for us-social-security-number=mask +``` + +That reflects the actual situation: a credential wants a typed marker so the +reader knows a key was rotated; a PII field often wants a mask so the shape of +the record survives. + +## Idempotence + +The marker grammar is allowlisted before any rule runs, so a second pass finds +nothing and re-running produces byte-identical output. This is what makes +re-sharing an already-redacted document safe, and it is cheap to get right up +front and painful to retrofit. + +Invariant to test: `redact(redact(d)) == redact(d)`. + +## Signatures + +`meta.signatures[]` on a step, path, or graph covers content the pass is about to +change, so redaction invalidates any signature over the redacted scope. v1 +refuses to redact a signed document unless `--drop-signatures` is passed, which +strips them and records the fact in the report. Silently leaving a broken +signature is not an option. + +## The audit record + +The pass records what it did, at the turn where it did it, without recording the +values. Toolpath's entire job is recording what happened to an artifact, so a +redaction that leaves no trace is off-format. + +**No new types.** The record rides the existing structs. Verified against the +schema: + +- `stepMeta` is `additionalProperties: true`, and `StepMeta.extra` is a + `#[serde(flatten)] HashMap`, so `Step.meta.extra["redaction"]` + is legal and needs no schema change. `Step.meta` is `Option`, so the + pass creates it where absent. +- `pathMeta` is likewise `additionalProperties: true`, so the document-level + rollup goes at `path.meta.extra["redaction"]`. +- `step` itself is `additionalProperties: false`, so the record cannot sit as a + sibling of `step`/`change`/`meta`. Inside `meta` is the only legal home. + +Per step, on the turn where the secret appeared: + +```json +{ + "step": { "id": "turn-0f3a", "actor": "agent:claude-opus-5", "...": "..." }, + "change": { "...": "..." }, + "meta": { + "redaction": { + "v": 1, + "findings": [ + { + "rule": "aws-access-key-id", + "at": "/change/claude:~1~1sess-abc/structural/tool_uses/0/result/content", + "n": 2, + "fp": "a3c829", + "op": "marker" + }, + { + "rule": "db-uri-password", + "at": "/change/src~1config.rs/raw", + "n": 1, + "fp": "7b1e04", + "op": "marker" + } + ] + } + } +} +``` + +`at` is an RFC 6901 JSON Pointer relative to the step object. Note the escaping: +artifact keys are URLs and file paths containing `/`, which becomes `~1` (and +`~` becomes `~0`), so `claude://sess-abc` addresses as `claude:~1~1sess-abc`. +That is fiddly enough to deserve a helper and a test of its own. + +`fp` is the same keyed fingerprint that appears in the marker, so a reader can +correlate: this step's finding and that step's finding are the same credential, +without either revealing it. + +The document-level rollup answers "what happened overall" without walking every +step: + +```json +{ + "path": { "id": "path-claude-code-0f3a2b71", "head": "turn-9c21" }, + "meta": { + "title": "Claude session: 0f3a2b71", + "kind": "https://toolpath.net/kinds/agent-coding-session/v1.1.0", + "redaction": { + "v": 1, + "at": "2026-07-30T18:04:11Z", + "tool": "toolpath-redact/0.1.0", + "ruleset": "gitleaks@8.28.0", + "mode": "marker", + "steps_touched": 4, + "replaced": { "aws-access-key-id": 2, "db-uri-password": 1 }, + "flagged": { "generic-assignment": 4 }, + "signatures_dropped": 0 + } + } +} +``` + +### What the record must not contain + +- **The value**, in any form. +- **Any substring of it.** A preserved prefix leaks the provider and the format, + hence the search space. +- **The original length.** Sentry's `_meta` records `len`, and that is a mistake + to copy here: for a fixed-format credential, length narrows the format space, + and combined with the rule id it is close to redundant with a prefix. The + marker's own length reveals nothing about the original. + +The record holds a *type*, a *location*, a *count*, and an opaque *handle*. That +is the honest account of what a reader is not seeing. + +### Consequences to handle + +- **The record must be allowlisted from scanning**, alongside the marker grammar. + A hex fingerprint in `meta.extra` would otherwise trip an entropy rule on the + next pass and the document would never converge. +- **Re-running merges, it does not append.** A second pass over an already + redacted document finds nothing new and leaves the existing record untouched, + which is what makes `redact(redact(d)) == redact(d)` hold at the byte level. +- **`extract_conversation` drops it**, because `Turn` has no field for step meta. + So a `path resume` of a redacted document shows the markers in the text but not + the structured record. That is acceptable: the marker carries the signal where + a reader will actually be looking. Worth revisiting if the IR ever grows an + escape hatch. +- **It changes the signed scope**, which is already covered by the + `--drop-signatures` rule above. + +## CLI + +``` +path p redact --input [--output ] + + detection --detector internal|keyhog|exec: (repeatable) + --threshold <0.0-1.0> (default 0.8) + --allow-network-detectors (off by default) + + plan --dry-run emit a plan, change nothing + --plan apply an existing plan + --reveal include real values in the plan (0600) + + decide --accept repeatable, last match wins + --reject + --interactive picker, TAB to toggle + --mode-for : + + transform --mode marker|remove|hash|mask|partial (default marker) + --key-file + + output --output --json + --drop-signatures +``` + +`--detector` is repeatable, so an internal sweep and an external scanner can run +together: + +```bash +path p redact --input claude-abc123 \ + --detector internal --detector exec:/usr/local/bin/gitleaks +``` + +The two-pass review flow that `--select flagged` exists for: + +```bash +# 1. see what a noisy heuristic thinks, change nothing +path p redact --input claude-abc123 --report-only --json > findings.json + +# 2. after review, apply only what was accepted +path p redact --input claude-abc123 --select flagged --output clean.json +``` + +`` is a cache id or a file path, matching `p render` and `p validate`. + +**In place is the point.** A cache id redacts the cached document where it sits. +There is no second file. + +The earlier design wrote a redacted copy elsewhere and left the cache untouched, +on the reasoning that the cache is a faithful archive. That was wrong, and the +reason it was wrong is the same reason `share` has no safety net: two documents +means remembering which one to send. Every downstream verb - `path resume`, +`path share`, `p export`, `p render` - resolves a cache id, so a redacted copy +sitting beside the original protects none of them. Redacting in place means once +you have redacted, everything downstream is redacted, without anyone having to +remember anything. + +What this gives up is the cache as an archive of original content. That is an +acceptable trade because **the cache was never the source of truth** - the +harness session log is, and `p cache sync` re-derives from it. The real cost is +narrower and worth stating plainly: once the source session ages out (30 days by +default, `cleanupPeriodDays`), the redaction is permanent and the original text +is gone. + +`--output` still exists and still writes elsewhere; it is how you redact a +standalone `.json` file, or keep a copy. With a file input and no `--output`, +output goes to stdout so it composes: + +```bash +path p redact --input doc.json | path p export pathbase --input - +``` + +In-place writes are temp-plus-rename at `0600`, matching `cache::write_cached`, +so an interrupted redaction never leaves a half-written document. + +## The sync collision, and how it is handled + +In-place redaction has one serious interaction, and it is not obvious. + +`sync::engine::is_unchanged` (`engine.rs:128`) gates re-derivation purely on the +source artifact's mtime and size plus the cache file existing. **It never +inspects the document.** So: + +- Redact in place, source session untouched → the next sync sees matching stamps + and skips.

It is additive, and every existing field +already carries `#[serde(default, skip_serializing_if)]`, so old manifests load +unchanged: + +```rust +pub(crate) struct SyncRecord { + // … path, cache_id, modified, size, synced_at … + #[serde(default, skip_serializing_if = "Option::is_none")] + pub(crate) redaction: Option, +} + +pub(crate) struct RedactionPolicy { + pub detectors: Vec, + pub threshold: f32, + pub mode: Transform, + pub mode_for: Vec<(String, Transform)>, + pub accept: Vec, // the predicates, verbatim + pub reject: Vec, + pub key_id: String, // which stored key produced the fingerprints +} +``` + +When sync re-derives an artifact whose record carries a policy, it re-runs +redaction with that policy before writing the cache. The document stays current +*and* stays redacted. + +Two honest limitations of replay: + +- **Only rule-based decisions replay.** A predicate re-evaluates against new + content correctly. An individually hand-picked finding cannot - its id and span + refer to content that may have moved. So anything the user individually + *skipped* comes back on re-derive. That is fail-closed, which is the right + direction, but it is surprising, so sync reports it: `re-redacted 3 documents; + 2 previously-skipped findings reappeared`. +- **The fingerprint key must persist.** A per-run random salt would give every + re-derive different markers and churn the document on every sync. The key is + stored once per document under `$TOOLPATH_CONFIG_DIR/redact-keys/` at `0600` + and referenced by `key_id`. This supersedes the "per-document random salt" + wording above: the salt is per-document and *persisted*, not per-run. + +`p cache rm` drops the key alongside the document. A record whose key is missing +fails loudly on re-redaction rather than silently producing new fingerprints. + +`--report-only` prints findings and writes no document: + +``` +$ path p redact --input claude-abc123 --report-only +7 findings in 4 steps + + replaced + aws-access-key-id 2 conversation.append.tool_uses[].result.content + db-uri-password 1 file.write.raw + flagged (not replaced, --include-heuristic to replace) + generic-assignment 4 conversation.append.text +``` + +Exit 0 when clean, 0 with findings after a successful redaction, non-zero only on +error. `--report-only` exits 1 when findings exist, so it works in a pre-share +check a user can wire up themselves. + +## Testing + +Mirrors the repo's existing style: unit tests alongside the code, integration +tests in `crates/path-cli/tests/`. + +- **Field map coverage.** One fixture document per change type, asserting the + right fields are visited and the wrong ones are not. +- **Detector contract.** A `FixedDetector` returning canned spans drives every + traversal and transform test, so those never depend on regex behaviour. Its + counterpart is a `HostileDetector` returning overlapping, reversed, + out-of-range and mid-codepoint spans, asserting the host normalises rather + than panics or corrupts. +- **Candidate shape dispatch.** Each `FieldShape` reaches the detector with the + right value and pointer, verified by a recording detector that captures every + `Candidate` it is handed. +- **Egress refusal.** A detector declaring `Egress::Network` errors without + `--allow-network-detectors`. +- **Selection modes.** `Auto` replaces above threshold and reports below it; + `Flagged` replaces exactly the previously recorded flags and detects nothing; + `Manual` replaces exactly what the map names and nothing else. +- **Non-destruction.** For a document with no secrets, `redact(d) == d` byte for + byte. This is the single most important test: the pass must not perturb + anything it is not redacting. +- **Lossiness guard.** A document carrying `extra["edits"]` and provider-specific + keys survives redaction with those keys intact. Directly guards against anyone + later "simplifying" the implementation into an extract/derive round-trip. +- **Idempotence.** `redact(redact(d)) == redact(d)` across all modes. +- **Diff integrity.** A redacted `file.write` raw diff still parses, and its hunk + headers still match its line counts. +- **Determinism.** Same input plus same key gives the same output, including + fingerprints, across runs and across HashMap iteration orders. +- **Signature refusal.** A signed document errors without `--drop-signatures`. +- **Round-trip untouched.** The existing fidelity suites still pass, confirming + the pass sits outside `derive_path` and the projectors. + +Corpus check: run against the local cache and confirm the known base rates from +the census reappear. + +## Decisions + +1. **Post-generation, not at egress.** Redaction belongs to the document, not to + one of its exits. Accepted cost: `path share` has no safety net. +2. **A new crate, not a module in `toolpath-convo`.** Keeps a regex engine and a + vendored ruleset off the seven provider crates. +3. **Mutate the `Path` in place; never round-trip through the IR.** The IR is + lossy by construction and a redactor cannot be built on a lossy transform. +4. **Typed markers with keyed fingerprints; no masking or partial redaction.** + Preserves what has analytical value and leaks nothing. +5. **Heuristic findings are reported, not replaced, by default.** 55% measured + noise makes auto-replacement worse than useless. +6. **Redact the cached document in place.** Every downstream verb resolves a + cache id, so a redacted copy beside the original protects none of them. The + cache stops being an archive of original content; the harness session log + already was one. Reversed from the first draft, which wrote a copy elsewhere. +7. **Detection is a plug point; traversal, transform and provenance are not.** + Detection is where the field moves fastest and where precision is worst. + Pinning the stable parts and swapping the volatile one is the point of the + abstraction. +8. **Detectors take strings plus context, never toolpath types.** Keeps them + testable in isolation, and keeps a future pre-tool-use path open without + rework at this layer. +9. **Networked detectors are refused unless explicitly allowed.** Validating a + candidate against its issuing provider is the failure this tool exists to + prevent, so it cannot be reachable by accident. +10. **Finding what to redact and deciding what to replace are separate axes.** + `--select flagged` makes "report, review, then apply" a first-class flow + rather than a workaround for a noisy detector. +11. **Sync re-applies redaction rather than clobbering it.** In-place redaction + without this is a silent un-redaction the moment the user resumes a session, + triggered implicitly by `path query`.
