fix: correct broken imports and fileno() guard after rebase

codex_auth.py was moved into contrib/codex/ but still used `.log`/
`.util` relative imports that resolved to the parent bot_bottle
package before the move — update to `...log` / `...util`.

_read_winsize() called sys.stdin.fileno() outside the OSError guard;
pytest's redirected stdin raises UnsupportedOperation (an OSError
subclass) there, breaking test_returns_first_tty_size. Move fileno()
inside the try block so any non-TTY stream is skipped cleanly.

+# PRD 0053: Egress DLP addon
+
+- **Status:** Active
+- **Author:** claude
+- **Created:** 2026-06-05
+- **Issue:** #195
+
+## Summary
+
+With pipelock removed (PR #193), the egress proxy no longer performs DLP
+scanning on traffic to or from the agent. This PRD implements a replacement
+directly inside the mitmproxy egress addon: per-route DLP detectors that
+scan outbound requests for credential leakage and inbound responses for
+prompt injection attempts.
+
+The manifest route schema is also upgraded in this PRD from the flat
+`path_allowlist` field to a structured `matches` block modelled on the
+[Kubernetes Gateway API `HTTPRoute`](https://gateway-api.sigs.k8s.io/reference/spec/#gateway.networking.k8s.io/v1.HTTPRouteMatch)
+match vocabulary. This upgrade is a hard cutover — no compatibility shim
+for the old format. The rationale and format survey are in the
+[YAML route matching formats research doc](https://gitea.dideric.is/didericis/bot-bottle/src/branch/main/docs/research/yaml-route-matching-formats.md).
+DLP detectors attach to the new `matches`-based routes directly.
+
+The design follows the recommendation in the
+[DLP research document (PR #192)](https://gitea.dideric.is/didericis/bot-bottle/pulls/192)
+and covers all three remaining implementation phases from that plan:
+
+1. Token pattern detection (Phase 1a)
+2. Known-secrets detection (Phase 1b)
+3. Naive prompt injection detection (Phase 2)
+
+## Problem
+
+Pipelock was removed because it could not support per-route response
+scanning, blocking selective DLP policies (e.g., skip scanning `.whl`
+downloads while keeping scanning on API calls). Removing it left the egress
+proxy with no DLP capability at all. The egress addon already holds per-route
+logic for path allowlisting and credential injection; DLP rules belong in the
+same place.
+
+The existing `path_allowlist` field is also limiting: it only supports path
+prefixes, with no way to express exact-path, regex, method, or header
+constraints. The Gateway API match vocabulary is a well-specified, widely
+deployed standard that covers all of these without inventing new syntax.
+
+## Goals / Success Criteria
+
+1. Outbound request bodies and headers are scanned for known token patterns
+   (AWS, GitHub, Anthropic, etc.) before the request reaches the upstream.
+   Matches are blocked immediately.
+2. Outbound request bodies are scanned for provisioned secrets that the
+   agent should not have direct access to. Matches are blocked immediately.
+3. Inbound response bodies are scanned for prompt disclosure and jailbreak
+   signals. High-confidence matches are blocked; medium-confidence matches
+   emit a log warning and are forwarded.
+4. DLP scanning is enabled by default on every route. Individual routes can
+   selectively disable outbound detectors, inbound detectors, or both via a
+   `dlp` block in the manifest.
+5. All detector logic lives in `egress_addon_core.py` (pure Python, no
+   mitmproxy dependency) and is covered by unit tests on the host.
+6. Each route's `matches` block supports path (exact/prefix/regex), HTTP
+   method, and header predicates using Gateway API match semantics.
+7. The manifest change is a hard cutover: `path_allowlist` is removed with
+   no fallback, no deprecation alias, and no loud exception for old-format
+   manifests. Old manifests that use `path_allowlist` will fail validation
+   at load time with an unknown-key error (same as any other unrecognised
+   key today).
+
+## Non-goals
+
+- LLM-based semantic prompt injection detection (explicitly deferred to a
+  potential Phase 2b per the research doc).
+- Entropy-based secret detection (excluded from scope; too many false
+  positives on binary API responses and compressed payloads).
+- BIP-39 seed-phrase detection.
+- Generic DLP (credit cards, SSNs, PII) — scope is narrow: AI/credential
+  exfil relevant to agent containment.
+- Changes to the cred-proxy sidecar.
+- Streaming response scanning (scan buffered response body only).
+- Glob-style path matching — regex covers every case glob would handle
+  without adding a third path-matching language.
+
+## Design
+
+### Route matching: Gateway API `matches` vocabulary
+
+The existing `path_allowlist` field is replaced by a `matches` list. The
+vocabulary mirrors Kubernetes Gateway API `HTTPRouteMatch` (see the
+[route matching research doc](https://gitea.dideric.is/didericis/bot-bottle/src/branch/main/docs/research/yaml-route-matching-formats.md)
+for a full format survey and rationale). Gateway API was chosen because it
+is spec-backed, implementation-tested across multiple proxies, and its
+`{type, value}` pattern is consistent and schema-validatable.
+
+**AND/OR semantics** (same as Gateway API):
+- Predicates *within* a single `matches` entry are ANDed.
+- Multiple entries in the `matches` list are ORed — the route matches if
+  any entry matches.
+
+```yaml
+egress:
+  routes:
+    # Bare route — all traffic to this host is forwarded (no path/method/header
+    # constraints). Equivalent to the old path_allowlist-omitted case.
+    - host: api.anthropic.com
+      auth:
+        scheme: Bearer
+        token_ref: EGRESS_TOKEN_0
+
+    # Two match entries (OR): GET/HEAD on /packages/** OR POST on /upload
+    - host: files.pythonhosted.org
+      matches:
+        - paths:
+            - type: prefix
+              value: /packages/
+          methods: [GET, HEAD]
+        - paths:
+            - type: exact
+              value: /upload
+          methods: [POST]
+      dlp:
+        inbound_detectors: false   # skip response scanning (binary downloads)
+
+    # Header + regex path — only JSON API responses on versioned endpoints
+    - host: internal-api.corp
+      matches:
+        - paths:
+            - type: regex
+              value: "^/v[0-9]+/"
+          headers:
+            - name: Content-Type
+              type: exact
+              value: application/json
+      dlp:
+        outbound_detectors: false
+        inbound_detectors: false
+```
+
+#### Path matching types
+
+| `type` | Semantics |
+|--------|-----------|
+| `exact` | Full path must equal `value` exactly |
+| `prefix` | Path must start with `value` at a segment boundary (matches `/api/v1` for value `/api/v1`, rejects `/api/v10`) |
+| `regex` | RE2 regex; rejected at load time if pattern fails to compile. Use for wildcard needs: `/api/[^/]+/data` instead of glob |
+
+`type` defaults to `prefix` when omitted (preserves the semantic of the
+old `path_allowlist`).
+
+#### Method matching
+
+`methods` is a list of HTTP method names, case-insensitive at parse time —
+`get`, `GET`, and `Get` are all accepted and stored as uppercase internally.
+An absent or empty `methods` list means all methods are permitted.
+
+#### Header matching
+
+`headers` is a list of `{name, value, type}` objects. ALL listed headers
+must match (AND semantics). To OR on header values, use multiple `matches`
+entries.
+
+| `type` | Semantics |
+|--------|-----------|
+| `exact` | Header value equals `value` (default when `type` omitted) |
+| `regex` | Header value matches RE2 regex |
+
+### Manifest schema — `dlp` block
+
+Each `egress.routes` entry gains an optional `dlp` key alongside `matches`
+and `auth`:
+
+```yaml
+egress:
+  routes:
+    - host: api.anthropic.com
+      # dlp omitted → all detectors on (default)
+
+    - host: files.pythonhosted.org
+      dlp:
+        inbound_detectors: false   # skip response scanning (binary downloads)
+
+    - host: internal-docs.corp
+      dlp:
+        outbound_detectors: false
+        inbound_detectors: false   # trusted internal, no scanning
+```
+
+`outbound_detectors` controls scanning of the *request* body + headers
+leaving the agent. `inbound_detectors` controls scanning of the *response*
+body arriving from the upstream.
+
+Valid values per field:
+- Omitted (or `null`) — default: all detectors active.
+- `false` — scanning disabled for this direction on this route.
+- A list of detector names — only the listed detectors run.
+
+Named outbound detectors: `token_patterns`, `known_secrets`.
+Named inbound detectors: `naive_injection_detection`.
+
+The manifest parser (`manifest_egress.py`) validates the `dlp` block and
+rejects unknown detector names.
+
+### `EgressRoute` changes
+
+`EgressRoute` replaces `PathAllowlist` with `Matches` and gains two new
+DLP fields. `MatchEntry` captures one AND-predicate block:
+
+```python
+@dataclass(frozen=True)
+class PathMatch:
+    type: str   # "exact" | "prefix" | "regex"
+    value: str
+
+
+@dataclass(frozen=True)
+class HeaderMatch:
+    name: str
+    value: str
+    type: str = "exact"   # "exact" | "regex"
+
+
+@dataclass(frozen=True)
+class MatchEntry:
+    paths: tuple[PathMatch, ...] = ()     # empty = match any path
+    methods: tuple[str, ...] = ()         # empty = match any method (uppercase)
+    headers: tuple[HeaderMatch, ...] = () # empty = match any headers
+
+
+@dataclass(frozen=True)
+class EgressRoute:
+    Host: str
+    Matches: tuple[MatchEntry, ...] = ()  # empty = match all requests
+    AuthScheme: str = ""
+    TokenRef: str = ""
+    Role: tuple[str, ...] = ()
+    OutboundDetectors: tuple[str, ...] | None = None   # None = all enabled
+    InboundDetectors: tuple[str, ...] | None = None    # None = all enabled
+```
+
+`manifest_egress.py`'s `from_dict` parses the new `matches` block and `dlp`
+block; `path_allowlist` is no longer a recognised key and will be rejected
+by the unknown-key check.
+
+### `Route` changes in `egress_addon_core.py`
+
+The addon-side `Route` and its helper types mirror the manifest-side changes.
+`match_route` is extended to evaluate the `Matches` list:
+
+```python
+@dataclass(frozen=True)
+class Route:
+    host: str
+    matches: tuple[MatchEntry, ...] = ()
+    auth_scheme: str = ""
+    token_env: str = ""
+    outbound_detectors: tuple[str, ...] | None = None
+    inbound_detectors: tuple[str, ...] | None = None
+```
+
+`decide()` feeds through `match_route` (unchanged host lookup) then
+evaluates the match entries in order; if the route has no `matches` entries
+all requests pass. Path `prefix` type uses segment-boundary checking
+(`/api/v1` matches `/api/v1/foo` but not `/api/v10`).
+
+### Detector interface
+
+Each detector is a pure function:
+
+```python
+def scan(body: str | bytes, *, env: Mapping[str, str] = {}) -> ScanResult | None:
+    ...
+```
+
+`ScanResult` carries:
+
+```python
+@dataclass(frozen=True)
+class ScanResult:
+    severity: str   # "block" or "warn"
+    reason: str
+```
+
+`scan` returns `None` if the body is clean, `ScanResult` otherwise.
+
+### Detector: `token_patterns`
+
+Regex patterns for well-known credential formats, applied to the outbound
+request body and `Authorization` header (before the addon strips it — the
+strip happens after DLP scanning so that the scan sees any credential the
+agent tried to smuggle):
+
+| Token type | Pattern |
+|------------|---------|
+| AWS access key | `AKIA[0-9A-Z]{16}` |
+| GitHub token (classic) | `ghp_[A-Za-z0-9_]{36}` |
+| GitHub fine-grained | `github_pat_[A-Za-z0-9_]{82}` |
+| Anthropic API key | `sk-ant-[A-Za-z0-9\-_]{93}` |
+| OpenAI API key | `sk-[A-Za-z0-9]{48}` |
+| Stripe live key | `sk_live_[A-Za-z0-9]{24}` |
+| Generic Bearer JWT | `Bearer\s+[A-Za-z0-9._\-]{50,}` |
+
+Action: `"block"` on any match. No tolerance — a credential in an outbound
+request is always a violation.
+
+### Detector: `known_secrets`
+
+At request time the egress addon has access to `os.environ`, which includes
+all `token_env` values declared by route auth blocks. The detector:
+
+1. Collects all `EGRESS_TOKEN_*` values from the environment (the naming
+   contract established by `manifest_egress.py`'s `TokenRef` rendering).
+2. For each secret value, derives encoded variants: raw, base64, URL-encoded,
+   hex.
+3. Scans the outbound request body for any variant.
+
+Action: `"block"` on match.
+
+This detector does **not** accept a custom detector name in the YAML — it
+is always named `known_secrets`. The environment is passed in via the `env`
+keyword argument to `scan`.
+
+### Detector: `naive_injection_detection`
+
+Pattern-based inbound response scanner. Uses two tiers:
+
+**Tier 1 — BLOCK (credential + disclosure together):**
+- Response contains a token-pattern match (reuses `token_patterns` regex
+  set) AND a prompt-disclosure phrase (e.g., `system prompt`, `my instructions
+  are`, `hidden rules`).
+
+**Tier 2 — WARN (multiple jailbreak signals):**
+- Two or more jailbreak phrases detected (e.g., `ignore previous`,
+  `forget everything`, `pretend you are`, `act as`).
+- OR explicit prompt disclosure (`system prompt:`) without a credential.
+
+**Tier 3 — ALLOW:**
+- Single jailbreak keyword without additional context.
+- Common documentation phrases.
+
+See the DLP research doc for the full phrase lists and pseudocode.
+
+### Wiring into `egress_addon.py`
+
+Two new mitmproxy hooks are added alongside the existing `request` hook:
+
+```python
+def request(self, flow: http.HTTPFlow) -> None:
+    # ... existing match + auth-injection logic ...
+    # After route decision, if action == "forward":
+    result = scan_outbound(route, flow.request, os.environ)
+    if result and result.severity == "block":
+        flow.response = http.Response.make(403, result.reason.encode(), ...)
+        return
+
+def response(self, flow: http.HTTPFlow) -> None:
+    route = match_route(self.routes, flow.request.pretty_host)
+    if route is None:
+        return  # already blocked at request time
+    result = scan_inbound(route, flow.response)
+    if result and result.severity == "block":
+        flow.response = http.Response.make(403, result.reason.encode(), ...)
+    elif result and result.severity == "warn":
+        sys.stderr.write(f"egress DLP warn: {result.reason}\n")
+```
+
+`scan_outbound` and `scan_inbound` are pure functions in
+`egress_addon_core.py` that dispatch to the per-route detector list.
+
+### Ordering: auth strip vs. DLP scan
+
+The DLP outbound scan sees the *agent's original* `Authorization` header
+before the addon strips it. This ensures that a token the agent smuggled
+in the header is caught. The strip + optional re-injection still happens
+afterward, preserving the existing credential-injection security model.
+
+## Implementation chunks
+
+1. **New `matches` block + `EgressRoute` / `Route` restructure.**
+   Remove `path_allowlist` from `manifest_egress.py` and `egress_addon_core.py`.
+   Add `MatchEntry`, `PathMatch`, `HeaderMatch` types. Parse `matches` in
+   `EgressRoute.from_dict` and `_parse_one`; unknown-key rejection handles
+   old `path_allowlist` manifests. Add `OutboundDetectors` / `InboundDetectors`
+   to `EgressRoute` and `Route`; parse `dlp` block. Extend
+   `tests/unit/test_manifest_egress.py` and `tests/unit/test_egress_addon_core.py`
+   with match and dlp valid/invalid cases.
+
+2. **Token-patterns detector (Phase 1a).**
+   New module `bot_bottle/dlp_detectors.py` (host-importable) and
+   companion flat copy for the sidecar bundle. Add `TokenPatternsDetector`
+   with the regex set above. Wire `scan_outbound` into the `request` hook
+   in `egress_addon.py`. Unit tests in `tests/unit/test_dlp_detectors.py`.
+
+3. **Known-secrets detector (Phase 1b).**
+   Add `KnownSecretsDetector` to `dlp_detectors.py`. Collect
+   `EGRESS_TOKEN_*` from env; derive encoded variants; scan request body.
+   Extend unit tests. Wire into `scan_outbound`.
+
+4. **Naive prompt injection detector (Phase 2).**
+   Add `NaiveInjectionDetector` to `dlp_detectors.py`. Wire
+   `scan_inbound` into the new `response` hook in `egress_addon.py`.
+   Extend unit tests. Activate PRD 0053 (`Status: Draft → Active`) in
+   this commit.
+
+## Open questions
+
+1. **Response body buffering:** mitmproxy's `response` hook already has
+   the full body for non-streaming responses. For streaming (chunked)
+   responses the body may be empty or incomplete at hook time. Scope for
+   now: log a warning and skip scanning on streaming responses; revisit
+   if needed.
+2. **Encoding breadth for `known_secrets`:** Start with raw + base64 +
+   URL-encoded + hex. Add GZIP / base32 if real-world evasion attempts
+   appear.
+3. **`EGRESS_TOKEN_*` naming contract:** The detector relies on the
+   env-var naming convention from `manifest_egress.py`. If that contract
+   changes, the detector must be updated in lock-step.

+# YAML route matching formats: paths, headers, and methods
+
+## Question
+
+Bot-bottle's egress manifest currently supports exact-host matching and
+a flat list of path prefixes (`path_allowlist`). As the DLP work (PRD 0053)
+and future route hardening evolve, we may want more expressive matching:
+glob-style path patterns (`/api/*/data`), header predicates (Content-Type,
+Accept), and per-method rules (GET allowed, POST blocked). What established
+YAML-based formats exist for declaring this kind of route matching, and
+which design choices should bot-bottle adopt?
+
+## Summary
+
+Four formats stand out as well-designed, widely deployed references:
+**Kubernetes Gateway API `HTTPRoute`**, **Envoy `RouteConfiguration`**,
+**AWS ALB listener rules**, and **Traefik dynamic routing**. A fifth,
+Istio `VirtualService`, is worth noting but is largely superseded by
+Gateway API for new designs.
+
+**Recommendation for bot-bottle:** adopt the Gateway API `HTTPRoute`
+match vocabulary as a direct model. It is the most carefully designed of
+the four, has a published spec, handles all three requirements cleanly, and
+its match object nests naturally into a YAML route block alongside
+bot-bottle's existing `host`, `path_allowlist`, and `auth` fields.
+Envoy's format is more powerful but far more verbose and harder to
+validate by hand; ALB rules use a flat predicate list that does not
+compose well; Traefik uses string expressions rather than structured YAML.
+
+## Current bot-bottle route schema
+
+```yaml
+egress:
+  routes:
+    - host: api.github.com
+      path_allowlist:
+        - /repos/myorg/
+      auth:
+        scheme: Bearer
+        token_ref: EGRESS_TOKEN_0
+```
+
+Matching today: exact host + path-prefix list. No method or header
+awareness.
+
+---
+
+## Format 1: Kubernetes Gateway API `HTTPRoute`
+
+**Spec:** [gateway.networking.k8s.io/v1](https://gateway-api.sigs.k8s.io/reference/spec/#gateway.networking.k8s.io/v1.HTTPRouteMatch)
+**Maturity:** GA (v1.0+, 2023). Backed by SIG Network; shipping in GKE,
+EKS, AKS, Istio, Envoy Gateway, Cilium, Traefik v3.
+
+### Match object
+
+```yaml
+rules:
+  - matches:
+      - path:
+          type: Exact          # Exact | PathPrefix | RegularExpression
+          value: /api/v1/data
+        headers:
+          - name: Content-Type
+            type: Exact        # Exact | RegularExpression
+            value: application/json
+        queryParams:
+          - name: version
+            type: Exact
+            value: "2"
+        method: GET            # GET | POST | PUT | DELETE | PATCH | …
+```
+
+A `matches` entry is a logical AND across all predicates within it. Multiple
+entries in the `matches` list are ORed: the rule fires if any entry matches.
+
+### Path matching
+
+| `type` | Semantics |
+|--------|-----------|
+| `Exact` | Full path must equal `value` (no trailing-slash equivalence) |
+| `PathPrefix` | Path must start with `value`; `/api` matches `/api/v1` but not `/apiv1` |
+| `RegularExpression` | RE2-syntax regex; implementations may differ on anchoring |
+
+**Glob-style paths (`/api/*/data`):** Gateway API does not define a glob
+type. The intent is to use `RegularExpression` for that case:
+`/api/[^/]+/data` replaces `/api/*/data`. This is unambiguous and widely
+understood.
+
+### Header matching
+
+```yaml
+headers:
+  - name: Content-Type
+    type: Exact
+    value: application/json
+  - name: X-Request-Id
+    type: RegularExpression
+    value: "[0-9a-f]{8}-.*"
+```
+
+All `headers` entries must match (AND semantics). Missing a header is a
+non-match (no "header absent" type in v1; implementations add it as an
+extension).
+
+### Method matching
+
+```yaml
+method: GET
+```
+
+Single method per match entry. To allow GET and POST, use two match
+entries (OR semantics at the matches level):
+
+```yaml
+matches:
+  - path:
+      type: PathPrefix
+      value: /api/v1
+    method: GET
+  - path:
+      type: PathPrefix
+      value: /api/v1
+    method: POST
+```
+
+### Strengths / weaknesses

+**Strengths:** spec-backed, implementation-tested, composable AND/OR
+semantics, explicit about what is not supported (no glob, no header-absent),
+good field naming (`type` + `value` pattern is consistent throughout).
+
+**Weaknesses:** verbosity when expressing OR across methods; regex is
+the only path wildcard mechanism; no body matching.
+
+---
+
+## Format 2: Envoy `RouteConfiguration`
+
+**Spec:** [envoy.config.route.v3.RouteMatch](https://www.envoyproxy.io/docs/envoy/latest/api-v3/config/route/v3/route_components.proto#config-route-v3-routematch)
+**Maturity:** Widely deployed (Istio data plane, AWS App Mesh, solo.io
+Gloo). Defined in protobuf; YAML is the human-readable rendering.
+
+### Match object
+
+```yaml
+match:
+  path: /exact/path              # exact match
+  # OR
+  prefix: /api/                  # prefix match
+  # OR
+  safe_regex:
+    google_re2: {}
+    regex: "/api/v[0-9]+/.*"
+  # OR
+  path_separated_prefix: /api/v1 # prefix with segment boundary enforcement
+
+  headers:
+    - name: content-type
+      string_match:
+        exact: application/json
+      # OR
+        prefix: text/
+      # OR
+        safe_regex:
+          google_re2: {}
+          regex: "application/(json|xml)"
+      invert_match: false        # negate the predicate
+
+    - name: x-custom-header
+      present_match: true        # just check presence
+
+  query_parameters:
+    - name: version
+      string_match:
+        exact: "2"
+```
+
+Method is matched via a pseudo-header:
+
+```yaml
+headers:
+  - name: :method
+    string_match:
+      exact: GET
+```
+
+Multiple methods require an OR combinator (`or_match`), available in
+Envoy v1.21+:
+
+```yaml
+headers:
+  - name: :method
+    or_match:
+      value_matchers:
+        - string_match:
+            exact: GET
+        - string_match:
+            exact: POST
+```
+
+### Path matching
+
+| Field | Semantics |
+|-------|-----------|
+| `prefix` | Path starts with value (any suffix allowed) |
+| `path` | Exact match |
+| `safe_regex` | RE2 regex (Google RE2 safety guarantees) |
+| `path_separated_prefix` | Like `prefix` but only matches at segment boundaries (`/api/v1` won't match `/api/v10`) |
+| `connect_matcher` | CONNECT method only |
+
+Glob (`/api/*/data`): use `safe_regex`: `/api/[^/]+/data`.
+
+### Strengths / weaknesses
+
+**Strengths:** most expressive format surveyed; `invert_match`, `present_match`,
+OR combinators, pseudo-header method matching; handles every edge case.
+
+**Weaknesses:** very verbose; protobuf-origin field names are not
+self-evident; `or_match` nesting is awkward; hard to validate in a
+lightweight schema check; not appropriate as a user-facing YAML format
+without a wrapping DSL.
+
+---
+
+## Format 3: AWS ALB Listener Rules
+
+**Spec:** [AWS Elastic Load Balancing API — Conditions](https://docs.aws.amazon.com/elasticloadbalancing/latest/application/load-balancer-listeners.html#rule-condition-types)
+**Maturity:** GA, widely used in AWS infrastructure-as-code (CloudFormation,
+Terraform `aws_lb_listener_rule`).
+
+### Match object (Terraform / CloudFormation rendering)
+
+```yaml
+conditions:
+  - field: path-pattern
+    path_pattern_config:
+      values:
+        - /api/*
+        - /health
+  - field: http-header
+    http_header_config:
+      http_header_name: Content-Type
+      values:
+        - application/json
+        - application/x-www-form-urlencoded
+  - field: http-request-method
+    http_request_method_config:
+      values:
+        - GET
+        - POST
+  - field: host-header
+    host_header_config:
+      values:
+        - "*.example.com"
+        - api.example.com
+  - field: query-string
+    query_string_config:
+      values:
+        - key: version
+          value: "2"
+```
+
+All conditions in a rule are ANDed. Multiple values within a single
+condition are ORed. Up to 5 conditions per rule.
+
+### Path matching
+
+ALB natively supports glob patterns in `path-pattern`:
+- `*` matches any sequence of characters (including `/`).
+- `?` matches any single character.
+
+This is the only surveyed format with first-class glob support. `/api/*/data`
+is valid and unambiguous. No regex support.
+
+### Header matching
+
+Header conditions match against the header value. Multiple values are ORed.
+The header name is fixed per condition block; to AND two header predicates,
+add two separate `http-header` conditions. Case-insensitive matching on
+values.
+
+### Method matching
+
+```yaml
+- field: http-request-method
+  http_request_method_config:
+    values:
+      - GET
+      - POST
+```
+
+Multiple values are ORed (GET or POST). Up to 40 methods per rule.
+
+### Strengths / weaknesses
+
+**Strengths:** first-class glob path matching (the only format surveyed
+with `*` and `?`); multi-value OR within a condition block is concise for
+the common case; method matching is a flat list, easy to write.
+
+**Weaknesses:** maximum 5 conditions per rule; no regex; no header-absent
+predicate; no request-body matching; the `field` + `*_config` naming is
+awkward (the field name is a string enum that determines which sibling key
+is relevant — a schema-validation anti-pattern); tied to AWS semantics
+(target groups, priority integers).
+
+---
+
+## Format 4: Traefik Dynamic Routing
+
+**Spec:** [Traefik Router Rule syntax](https://doc.traefik.io/traefik/routing/routers/#rule)
+**Maturity:** GA, widely deployed in Kubernetes (IngressRoute CRD) and
+Docker-Compose setups. Traefik v3 aligns with Gateway API for Kubernetes
+routes but keeps its own expression syntax for the `rule` field.
+
+### Match expression (string, embedded in YAML)
+
+```yaml
+http:
+  routers:
+    my-router:
+      rule: >
+        Host(`api.example.com`) &&
+        PathPrefix(`/api/v1`) &&
+        Method(`GET`, `POST`) &&
+        Header(`Content-Type`, `application/json`)
+      service: my-service
+```
+
+`&&` = AND, `||` = OR. Parentheses for grouping.
+
+Available matchers:
+
+| Matcher | Example |
+|---------|---------|
+| `Host` | `Host("api.example.com")` |
+| `HostRegexp` | `HostRegexp(".*\.example\.com")` |
+| `Path` | `Path("/exact/path")` |
+| `PathPrefix` | `PathPrefix("/api/v1")` |
+| `PathRegexp` | `PathRegexp("/api/v[0-9]+/.*")` |
+| `Method` | `Method("GET", "POST")` |
+| `Header` | `Header("Content-Type", "application/json")` |
+| `HeaderRegexp` | `HeaderRegexp("Accept", "application/.*")` |
+| `Query` | `Query("version", "2")` |
+| `QueryRegexp` | `QueryRegexp("id", "[0-9]+")` |
+| `ClientIP` | `ClientIP("10.0.0.0/8")` |
+
+Glob paths: not supported directly. Use `PathRegexp` instead.
+
+### Strengths / weaknesses
+
+**Strengths:** the most expressive and concise format for complex boolean
+combinations (AND/OR/NOT in a single line); `Method("GET", "POST")` is
+the cleanest multi-method syntax surveyed; full regex support on every
+field; Traefik v3 supports this inside Kubernetes CRDs.
+
+**Weaknesses:** the rule is a *string* embedded in YAML, not a structured
+object — it cannot be validated with JSON Schema and is harder to generate
+programmatically; no structured round-trip; no glob, only regex.
+
+---

+
+## Design choices worth adopting
+
+### 1. Match object as a structured peer to `host`
+
+Gateway API's separation of concerns maps well onto bot-bottle's existing
+schema. Instead of a flat `path_allowlist`, a `match` block nests all
+predicates:
+
+```yaml
+egress:
+  routes:
+    - host: api.github.com
+      match:
+        paths:
+          - type: prefix       # exact | prefix | glob | regex
+            value: /repos/myorg/
+        headers:
+          - name: Content-Type
+            value: application/json
+        methods: [GET, POST]
+      auth:
+        scheme: Bearer
+        token_ref: EGRESS_TOKEN_0
+```
+
+All predicates within `match` are ANDed. A list of `paths` entries is
+ORed (first match wins — same as the current `path_allowlist` semantics).
+
+### 2. Path type enum (`exact` | `prefix` | `regex`)
+
+Use three named types rather than inferring from the value's syntax. This
+avoids the ambiguity that plagues `.gitignore` and `nginx location` patterns
+where the same string can mean different things depending on leading characters.
+
+- `prefix`: mirrors current `path_allowlist` semantics.
+- `regex`: RE2 for wildcard and advanced cases. Reject at load time if the
+  pattern fails to compile. Covers every case glob would handle —
+  `/api/[^/]+/data` is the `/api/*/data` equivalent.
+
+Glob-style syntax is not included: it adds a third path-matching language
+on top of prefix and regex without meaningful operator benefit, since regex
+is already required for any non-trivial wildcard.
+
+### 3. Header matching as a list of `{name, value, type}` objects
+
+Mirrors Gateway API exactly. ALL headers must match (AND). `type` defaults
+to `exact`; `regex` is available. No header-absent for now (adds complexity,
+low immediate need).
+
+```yaml
+headers:
+  - name: Content-Type
+    value: application/json         # type: exact (default)
+  - name: X-Internal-Key
+    value: "dev-[0-9]+"
+    type: regex
+```
+
+### 4. Method list as a flat enum list
+
+Adopts ALB's conciseness. An empty or absent `methods` list means all
+methods are permitted. Values are uppercased HTTP method names.
+
+```yaml
+methods: [GET, HEAD]
+```
+
+### 5. Multiple `match` entries per route: OR semantics at the route level
+
+If a route needs GET on one path and POST on a different path, use a
+`matches` (plural) list where entries are ORed:
+
+```yaml
+routes:
+  - host: api.example.com
+    matches:
+      - paths: [{type: prefix, value: /read}]
+        methods: [GET, HEAD]
+      - paths: [{type: exact, value: /write}]
+        methods: [POST, PUT]
+```
+
+This mirrors Gateway API's top-level OR; each entry is an AND of its
+predicates.
+
+---
+
+## Decisions
+
+The open questions raised during research were resolved in PR #196 review:
+
+1. **Backward compatibility:** Hard cutover. The new `matches` structure
+   replaces `path_allowlist` entirely with no compatibility shim and no
+   fallback parsing for the old format. Manifests using `path_allowlist`
+   must be migrated.
+
+2. **Glob support:** Dropped. Not strictly necessary — `regex` covers every
+   case glob would handle. Fewer path-matching languages to document and
+   validate.
+
+3. **Header value OR:** Stick with Gateway API. OR across header values
+   requires a separate entry in the `matches` list, not multiple values
+   inside one `headers` block.
+
+4. **Method name case:** Case-insensitive at parse time. `get`, `GET`, and
+   `Get` are all accepted and normalised to uppercase internally.
