Each new input is off until you configure it. + +### Added + +- **Spec-grounded review (`--spec`, `PRXREF_SPEC_SOURCES`).** Name web pages, + local spec files or directories, and Jira ticket URLs with a repeatable + `--spec URL_OR_PATH` or the list-valued `PRXREF_SPEC_SOURCES`. prxref fetches + them, prunes them to a digest of the constraints relevant to this diff + (`PRXREF_SPEC_MAX_CHARS` caps each fetched text, `PRXREF_SPEC_DIGEST_TOKENS` + the digest), and puts the digest into every chunk worker's and the whole-PR + sweep's prompt. A diff that breaks a quoted constraint draws a finding of the + new 🔍 `spec` severity, ranked below `warning`. Spec findings are advisory: + they never change the verdict or count toward the error cap, and + `PRXREF_FAIL_ON=any` is the opt-in gate. A source that fails never blocks the + review; the summary's grounding note lists it as `source N (kind): reason`. + The digest keeps hard-wrapped statements whole, splits a long or multi-rule + block into one MUST/SHOULD/MAY unit per sentence, files each constraint under + its own section heading (Markdown, setext or HTML `

`–`

`), turns a + version pin on a line of its own into a MUST, and ranks constraints by the + diff's content words while ignoring normative ones such as `must` or + `required`. Each URL or Jira source gets a 15 s socket timeout, a 30 s + wall-clock budget and one retry with no backoff (`Retry-After` is ignored), + and a page served without a charset is decoded by its `` tag, then as + UTF-8, then as cp1252. See the README's "Review Against a Spec or Ticket", + `docs/quality.md` "Spec grounding" and `docs/deploy.md` "Spec Sources in CI + and on the Daemon". +- **A `spec` finding has to be earned.** A run counts as spec-grounded only when + at least one constraint reached the prompts. When every source failed or none + held a constraint, nothing is injected, the prompts say that no specs were + provided, and a `spec` finding the model returns anyway is posted as a + `warning` (logged at INFO and counted by a `specs relabel` trace event). On a + grounded run the hedge gate skips the text that a finding's `Spec: "…"` quote + copies verbatim from the digest, compared case-insensitively and in a finding + of any severity, so a condition that belongs to the spec ("If a session + already exists, the server MUST …") does not drop the finding as hedged. A + quote the digest does not hold exempts nothing. +- **Jira tickets as spec sources.** A Jira issue URL (`/browse/KEY-1` or a REST + issue URL, either one under a context path of up to two segments, a Cloud + team-managed issue view, or a board URL carrying `selectedIssue`) is read from + Jira REST, and the ticket's summary, type, labels and description lines rank + ahead of every other constraint. `PRXREF_JIRA_BASE_URL`, `PRXREF_JIRA_EMAIL` + and `PRXREF_JIRA_API_TOKEN` configure access (see Security for where the + credentials go). A 401, a 403 or an anonymous 404 comes with a credentials + hint, and a 200 that is not a JSON issue, such as an SSO login page, fails + that source with a clean message. +- **Spec grounding in the log, the run record and the trace.** Each failed + source logs one WARNING, `spec source N/T (kind, origin) failed + (best-effort): reason`, in every run mode, with a URL origin cut to + `scheme://host[:port]/path`. Every run with spec sources logs one INFO line, + `spec grounding: ok/T source(s) ok, N constraint(s) injected`. The run record + and `--format json` carry `spec_grounding` (`sources`, `ok`, `failed`, + `constraints`, `digest_sha256`), and the trace's `specs` event is `ok`, or + `fail` with the `reasons` when no source was fetched or the stage crashed. +- **Azure DevOps Repos forge (#2).** `prxref review` and `prxref serve` handle + Azure DevOps Services (`dev.azure.com`, `*.visualstudio.com`) and Azure DevOps + Server (any host, with the collection in the URL). Inline findings post as + active threads, the summary is one closed PR-level thread that later runs + update in place, and stale inline comments of prxref's own are pruned. Azure + DevOps has no unified-diff endpoint, so the diff is rebuilt from the Diffs API + (merge-base semantics) plus blob contents: pure renames and known-binary files + are never downloaded, and a file past the per-blob, file-count or byte budget + keeps its header without hunks. Authentication is `PRXREF_AZURE_DEVOPS_TOKEN` + (a PAT), else `SYSTEM_ACCESSTOKEN` inside Azure Pipelines, else anonymous + reads of a public project. The webhook server accepts the + `git.pullrequest.created` and `git.pullrequest.updated` service hooks for an + active PR, checking the HTTP Basic password against + `PRXREF_AZURE_DEVOPS_WEBHOOK_SECRET` in constant time (unset, it answers 401 + unless `PRXREF_ALLOW_UNSIGNED=1`). The CLI help, the unrecognized-URL hint and + the package description name Azure DevOps; setup is in `docs/forges.md` + section 5 and `docs/deploy.md`. +- **Team review rules (#3).** `--rules-file PATH` or `PRXREF_REVIEW_RULES` names + a Markdown or plain-text checklist. Its body goes into the system prompt of + every chunk worker and the sweep, under a `## Team review rules` heading and + inside `` tags, and `PRXREF_REVIEW_RULES_MAX_CHARS` (default + 12000) caps it, with a truncation line and one WARNING. An optional `severity:` + front-matter block maps team words onto `error`, `warning` or `outofscope` + (`blocker: error`), and a mapped word the model writes is rewritten before + every quality pass instead of being dropped as an invalid severity; `spec` is + not a target, and prxref's own severities cannot be remapped. Other + front-matter keys are ignored, so a skill file works unmodified. The run + record's `review_rules` holds the path, the raw file's SHA-256, the lengths, + the truncation flag and the severity map, never the text; `-v` prints a + `rules:` line, and the trace gains `rules ok` and `rules remap` events. + `--rules-file ""` turns an environment-configured file off for one run, an + unusable file exits 2 before any network call, and the webhook server + re-reads the file for every review. See `docs/review-rules.md`. +- **Ticket context and a per-finding scope (#4).** `--context-file PATH` or + `PRXREF_TICKET_CONTEXT_FILE` names the ticket a PR implements, and every + finding is judged `in`, `out` or `unknown` against it. The ticket is quoted to + the model as fenced, untrusted data, capped by `PRXREF_TICKET_CONTEXT_MAX_CHARS` + (default 6000). An out-of-ticket finding is marked 🟦 in front of its severity + glyph, listed last in the summary under **🟦 Outside the ticket (N)**, + labelled `OUTSIDE TICKET` in its inline comment, yields inline slots to + in-ticket findings of the same severity, and ends in `[scope: out]` in CLI + text. Scope never feeds dedup, the error cap, the verdict or `PRXREF_FAIL_ON`. + An empty file means "this PR has no ticket" and the summary says so, and a + ticket without acceptance criteria (an `Acceptance criteria` or `Definition of + done` heading or label, a task-list item, or a Gherkin `Given` … `Then`) gets + a note that scope was judged from its description alone. Every finding in + `--format json` carries `scope`, which stays `unknown` without a ticket; the + record's `ticket_context` holds metadata only. The webhook server never reads + a ticket file, and warns once at startup if the variable is set. +- **Replay mode for evaluation (#5).** `--base-sha` and `--head-sha` review a + pinned commit range (the merge-base diff, with file context read at the + pinned head), `--no-threads` hides the PR's existing discussion, and + `--diff-file` reviews a diff file, with `--pr-url` or with no forge at all + (a `git format-patch` mail's subject, body and author become the PR's title, + description and author). A replay never posts, even for a library caller that + passes `post=True`; a blank replay diff is an `Error` run rather than an + `Approved` one; and the run record gains a `replay` stamp. Every built-in + forge implements the new optional `Forge.get_compare_diff(ref, *, base_sha, + head_sha)`, and `docs/forges.md` documents each forge's endpoint and caveats. +- **Subscription CLI backends: `claude-cli` and `kiro-cli` (#6).** + `PRXREF_LLM_BACKEND=claude-cli` or `kiro-cli` reviews with your own installed, + logged-in Claude Code or Kiro CLI instead of an HTTP endpoint: one process per + model attempt, started from a fresh temporary directory, with the diff on + stdin. `claude-cli` runs `claude -p` with no built-in tools, settings files, + MCP servers or saved session; it removes eight credential-routing variables + (`ANTHROPIC_API_KEY`, `ANTHROPIC_BASE_URL`, `CLAUDE_CODE_USE_BEDROCK` and the + like) from the child's environment so the call stays on your subscription + login, maps `PRXREF_LLM_REASONING_EFFORT` to `--effort`, and warns if the CLI + reports an API-key source, loads tools anyway, or reports a rate-limit status + other than `allowed`. `kiro-cli` runs `kiro-cli chat --no-interactive` on the + v2 agent engine, with a per-call agent file that carries the system prompt and + the model and allows no tools, MCP servers or resources. `PRXREF_LLM_MODELS` + is walked as a fallback chain, `PRXREF_LLM_CLI_PATH` overrides the binary, + `PRXREF_LLM_CLI_CONCURRENCY` (default 2) caps the processes running at once, a + deadline miss kills the whole process group, and a missing CLI exits 2 before + any forge or model call. See the "Subscription CLI backends" section of + `docs/llm.md`. +- **Dollar cost in the run record (#7).** `cost_usd` is the total of the + review's calls, the chunk workers plus the sweep, including truncated or + unparseable responses that were billed, and `0.0` when no model call went + out. A figure the backend reported always wins: the response body's + `usage.cost` (OpenRouter), the `x-litellm-response-cost` header (a LiteLLM + gateway or llm-ferry), litellm's `response_cost`, or the Claude Code CLI's + `total_cost_usd`, an API-equivalent at list price rather than what a + subscription is billed. Otherwise the cost is estimated from + `PRXREF_PRICE_TABLE` (inline JSON or a JSON file path, USD per million tokens, + keyed by exact model name, validated at load so a malformed table exits 2), + and `cost_estimated` is set. Otherwise it is `null`, never `0` and never a + partial sum, and one INFO line names the unpriced models. `PRXREF_POST_COST=1` + appends the cost to the posted attribution line, `-v` prints it (`$…`, + `$… (API-equivalent)`, `~$… (est.)` or `cost unknown`), and the `chunk ok`, + `sweep ok` and `run ok` trace events, each unit's `.meta.json` + (`cost_usd`, `cost_source`) and the openai-compat attempt log line (`cost=`) + carry it. A run whose every reported figure came from the Claude Code CLI + shows its cost as `$0.0202 (API-equivalent)` on the `-v` line and on the + posted attribution, because `total_cost_usd` is the API list price, not a + subscription bill; an estimated run keeps `~$… (est.)`. The run record marks + such a run with `cost_api_equivalent: true`, a key no other run carries, and + `--format json` gains no key, because each unit's `cost_source` already says + `claude-cli`. prxref never asks a provider to add usage to a response. See + `docs/llm.md` "Cost accounting". +- **PR size advisory (#8).** Set `PRXREF_SIZE_WARN_LINES` (lines added plus + removed) and/or `PRXREF_SIZE_WARN_FILES` (files changed), and a PR strictly + above either one gets a line at the top of its summary: "This PR changes N + lines in M files, above the team guideline of … Consider splitting it." Both + are off by default, and `0` is a real threshold. The counts come from the + parsed diff and skip lockfiles from the common ecosystems, generated files + (`*.snap`, `__snapshots__/`, `*.min.js`, `*.map`, `*.generated.*`, + `*.auto.*`) and any path matching `PRXREF_SIZE_IGNORE_GLOBS`. The advisory + never changes the verdict or the exit code; it is also reported as + `size_advisory` in the run record and `--format json`, and as a + `size advisory:` line in the CLI output. +- **New run-record and `--format json` keys.** `cost_usd`, `cost_estimated`, + `review_rules`, `ticket_context`, `spec_grounding` and `size_advisory` are + present on every exit, error and empty-diff exits included, and `null` when + their feature is off. In `--format json` they follow the existing keys in a + fixed, documented order, and a replay run adds `replay`. The CLI text output + gains a `replay:` line on a replay, and `-v` adds `rules:`, `ticket:` (with the + in/out/unknown counts) and `spec:` lines. The README's "CLI Flags" section now + documents every `review` flag and lists the JSON keys in payload order. + +### Changed + +- **Minor findings render ⬜, and 🟦 now means "outside the ticket".** + `outofscope` findings and unrecognised severities show a grey square in the + summary counts, the findings list, inline comment headers and the library + formatter, where 0.13.0 showed 🟦; the JSON value and the `OUTOFSCOPE` label + are unchanged. The summary counts line also gains a `🔍 N spec` count on + every run. Every glyph now comes from one table, `prxref.markers`. +- **The review prompts changed for every run.** The worker and sweep prompts + define the `spec` severity and its rules, and carry a `### Spec constraints` + block that reads `(no specs provided for this review)` when none are + configured, so a review of the same diff can differ from 0.13.0's even with + none of the new inputs set. +- **An unrecognized `PRXREF_LLM_BACKEND` is a configuration error (exit 2)** + that names the variable and lists the six accepted values, checked before any + other LLM setting. In 0.13.0 it was a failed review that exited 0. +- **`PRXREF_LLM_MODELS` splits on whitespace as well as commas**, like the new + list-valued `PRXREF_SPEC_SOURCES` and `PRXREF_SIZE_IGNORE_GLOBS`. 0.13.0 split + it on commas only. +- **GitLab MR diffs are requested without `access_raw_diffs`.** Every earlier + release sent it to `/merge_requests/:iid/diffs`, which ignores it: gitlab.com + returned byte-identical diffs with and without it, and only the deprecated + `/changes` endpoint reads it. The reviewed diff is unchanged. + +### Fixed + +- **The `litellm` backend no longer requires `PRXREF_LLM_BASE_URL` (#1).** Only + `openai-compat`, `ferry` and `http` need it. Set on any other backend, it is + ignored with one INFO line and never forwarded, so a deployment that set a + placeholder URL to get past the old check keeps working unchanged. To use a + LiteLLM proxy, choose `openai-compat`. +- **GitLab merge requests with more than 20 files are reviewed in full.** The + adapter read only the first page of GitLab's MR diff list, 20 files by + default, and dropped every file after that without saying so. It now reads + every page, and a page that cannot be read fails the review with an error + naming it instead of reviewing part of the MR. A warning names each file + GitLab sends without hunks (`too_large` or `collapsed`). +- **GitHub and GitHub Enterprise API calls time out**: 10 s to connect and 30 s + per read, the same as the other forges. A stalled GitHub connection could + hang the review, and the webhook worker running it, forever. A write that + times out is not retried, so it cannot post a duplicate comment. +- **A `{placeholder}` in PR text is shown literally.** A PR title or + description containing `{diff}` had the diff pasted into the prompt at that + spot, and a PR or finding title containing `{findings}` or `{attribution}` did + the same to the posted summary. Prompts and the summary are now filled in a + single pass. +- **`load_config` no longer shares list defaults between calls.** Appending to + one loaded config's `llm_models` changed the default that every later load + started from. +- **Under `PRXREF_FAIL_ON=error` or `any`, a review that ends with verdict + `Error` exits 1**, as documented since 0.4.0. Before, only a crash did: a + forge that could not be read, a diff that could not be parsed or chunked, and + a review in which every chunk failed all return an `Error` result rather than + raising, so a gating lane read those broken runs as green. The default + `never` is unchanged. +- **A total LLM failure no longer counts a successful sweep as failed.** When + every chunk worker failed but the whole-PR sweep answered, the run correctly + ended with verdict `Error` but reported `chunks_reviewed` 0 and every review + unit failed. It now counts the sweep as reviewed: `chunks_reviewed` is 1, + `chunks_failed` is the number of chunks, and the two still add up to + `chunk_count`. The text output therefore reads `coverage: 1/2 chunks + reviewed` on a one-chunk PR. The verdict, the posted error notice and the + `PRXREF_FAIL_ON` exit code are unchanged. +- **The `forge.get_diff` trace span counts bytes.** Its `bytes` field counted + characters, so a diff with non-ASCII text or a byte-order mark read short + (15,647 against 15,651 on one live Azure DevOps pull request). +- **Documentation corrections.** `docs/deploy.md` no longer says there is no + `PRXREF_FAIL_ON` (there is: `never`, `error` or `any`, default `never`), its + exit-code table gains the `1` row, and its webhook table lists the Bitbucket + Cloud events prxref accepts (`pullrequest:created`, `pullrequest:updated`) and + gains Bitbucket Server / Data Center and Azure DevOps rows. `.env.example` and + `docs/env-vars.md` no longer say that an unset `PRXREF_LLM_SEED` leaves the + seed out of the request: prxref sends one random seed per process and reports + it as `sampling.seed`. `docs/llm.md` names the backends that apply the seed, + the reasoning effort and the max-tokens settings. `docs/forges.md` documents + GitLab's paged diff listing, and that reading a merge request's threads on + gitlab.com needs `PRXREF_GITLAB_TOKEN` even for a public project: gitlab.com + answers anonymous `/notes` and `/discussions` requests with HTTP 401, so a + tokenless review logs `discussion feed read was incomplete` and dedups against + no threads. + +### Security + +- **Earlier releases were withdrawn and the history rewritten.** The published + sdists of 0.10.1 through 0.13.0 and the wheels of 0.12.0 through 0.13.0 were + removed from PyPI, so 0.12.0 through 0.13.0 can no longer be installed from + it. The git history before 0.14.0 was rewritten to drop internal planning + notes: every tag and nearly every commit before 0.14.0 has a new SHA, so + re-clone an existing clone rather than pulling into it. +- **Files named by path stay inside the working directory.** A rules file, a + ticket-context file or a local spec source that sits under the working + directory, such as a file committed in a PR checkout, must still resolve + under it once its symlinks are followed. So a committed + `docs/SPEC.md -> ~/.ssh/id_rsa` is refused without revealing the link target, + and every symlinked entry inside a spec directory is skipped. An absolute path + outside the working directory is the operator's own choice and is read as + given.

The digest names a spec source to the model only by its last path + segment or bare host, with no query, userinfo, port or full local path (a + credential that is itself the last path segment still gets through), and the + spec failure reasons the summary posts carry no local path. The run record + and the trace hold a rules or ticket file's metadata, never its text. + +### Known limitations + +- **Unpunctuated spec lines merge.** Consecutive keyword lines in one paragraph + that end without punctuation (a list with no bullets or full stops) become a + single constraint labelled with the strongest keyword among them, and a run + of them longer than 400 characters is cut at 400, losing the rest. End each + rule with a full stop, or make it a list item. +- **A `Spec: "…"` quote that never closes is barely exempt.** The hedge gate + exempts a quote only up to a closing quote mark. A quote with no closing + quote, or one that departs from the digest's wording before it closes, is + exempt only up to its last inner quote mark, and not at all without one, so a + condition inside it can still drop the finding as hedged. +- **A spec directory is read shallowly.** A directory source reads at most the + first 20 `.md`, `.markdown`, `.txt` or `.adoc` files directly inside it, by + name, and says nothing about the rest. Files it skips as unreadable or + symlinked are named in a WARNING log line only, not in the posted note, the + run record or the trace. +- **A spec directory's constraints are not tagged per file.** They carry the + directory's name and a line number counted through its files joined together, + each file under a `## ` heading, rather than the file's own name + and line. +- **A Jira ticket can crowd out the spec.** Ticket lines rank ahead of every + other constraint and may fill up to 6,000 characters of the digest, a fixed + share (half the default `PRXREF_SPEC_DIGEST_TOKENS` budget) that does not + shrink with `PRXREF_SPEC_MAX_CHARS`. With a smaller digest budget, a long + ticket can leave no room for anything else. +- **A `spec` finding's quote is not checked against the digest.** On a + grounded run, a `spec` finding keeps its severity even when the constraint it + quotes is not in the digest; only the hedge-gate exemption requires a match. +- **A Jira ticket passed with `--spec` is not ticket context.** It grounds + `spec` findings but sets no finding's scope; to judge scope, pass the + ticket's text with `--context-file`. +- **Spec grounding can crowd out a generic finding.** In the bundled eval, + case-002's one expected non-spec finding was missed in all 4 grounded runs, + across two models, and found in 3 of the 4 runs without the spec. That is two + runs per model in each arm, and the cause, grounding displacing generic + review, is inferred, not proven. +- **`kiro-cli` runs always read "cost unknown".** Kiro meters credits, not + dollars, and reports no token counts, so a price table cannot estimate it + either; each call's INFO line carries the credits instead. +- **`kiro-cli` isolation and reporting are partial.** Whether Kiro adds + user-level configuration, such as `~/.kiro/steering/`, to prxref's per-call + agent has not been verified, and the agent file cannot turn it off. Kiro does + not report which model ran, so the attribution names the model you + configured, and it keeps every chat, the diff included, under + `~/.kiro/sessions/cli/` (`docs/llm.md` shows how to delete them). +- **GitLab files without hunks are not reviewed.** A file whose diff GitLab + withholds as `too_large` or `collapsed` arrives without hunks, so it is listed + header-only and not reviewed; a warning names each such file. +- **GitLab merge requests past 5,000 files fail.** An MR whose diff listing runs + past 50 pages of 100 files fails the review rather than reviewing part of it. +- **GitHub pull requests past 20,000 diff lines are not reviewed.** GitHub + refuses the unified diff of such a pull request with HTTP `406` + (`too_large`), so the review ends with verdict `Error` and posts the error + notice. There is no fallback to the paged file listing yet. This limit + applies to every earlier release too. +- **A forge-less replay sees only the diff.** A `--diff-file` run without + `--pr-url` gives the workers no library versions and no out-of-hunk + definitions, gives the manifest claim check no full-file lines, and has no + existing discussion; its title and description come from a `git format-patch` + header when there is one, else the file name. With `--pr-url`, a replay keeps + the PR's current title and description, pinned SHAs without `--no-threads` + still show the current threads, and a `--diff-file` without `--head-sha` reads + file context at the PR's current head; the last two each log a warning. +- **Azure DevOps is verified live for anonymous reads only.** On a public Azure + DevOps Services project, the forge reads, the dry-run output shape, the + pinned-range compare diff (including a PR whose target branch had moved on) + and a pinned-range replay were checked live.

GitHub calls time out. + Prompts and the summary fill in a single pass, so a `{diff}` in PR text stays + literal. `load_config` no longer shares list defaults between calls. An + unrecognized `PRXREF_LLM_BACKEND` exits 2. Under `PRXREF_FAIL_ON=error` or + `any`, a review that ends with verdict `Error` exits 1. A total LLM failure + counts the sweep that answered, and the `forge.get_diff` trace span counts + bytes, not characters. +- **Config went from 36 to 55 keys.** The 19 new keys are the CLI path and + concurrency, cost, size, spec, rules and ticket keys, the Jira credentials, and + the Azure DevOps token and webhook secret. + +## What this release taught + +Written down because each one cost a seat real time. + +1. **Lay the seams first, and make every stub fail closed.** A foundation stage + landed every shared surface with a placeholder body before any feature seat + started: config keys, run-record and JSON keys, prompt slots, trace events, + the glyph table and the new `Forge` method. That let the eight issue seats run + in parallel on disjoint files. A stub that fails closed cannot ship as a + silent no-op. The cost is that placeholder prose outlives the placeholder. + Docstrings saying the loaders "fail closed in this build" and the cost hooks + are "inert in this build" survived after the real bodies landed, and the + release had to sweep them. Grep for `in this build` before cutting. +2. **Cite the symbol, not the line.** Several seats found the `file:line` pins in + their briefs stale against the base they had been given, and every one of + them still resolved by symbol name. Pin a SHA if you must give a line, and + prefer `module.function`. +3. **Keep one table per cross-cutting literal.** Every severity and scope glyph + comes from `prxref.markers`, and `tests/test_markers.py` + (`TestGlyphsLiveInOnePlace`) fails when a glyph literal turns up anywhere else + in the package. So a glyph change is made in one table, and the test finds + any stray copy. +4. **`Tracer.event(node, phase, **meta)` reserves two keyword names.** A dict + splatted into it must not carry a `node` or `phase` key. Such a call raises + `TypeError` at the call site, before tracing's never-raise guard can catch it. +5. **A mutation check needs `PYTHONDONTWRITEBYTECODE=1`.** To prove a test can + fail, revert a line, watch the test go red, then restore the line and `cmp` it. + Without the variable, the mutant's bytecode gets cached. A same-size restore + within the same second can then run the mutant again. +6. **Two contract rules over one field need a tiebreak.** One rule said every + new JSON key is always present and `null` when its feature is off. Another + said `replay` is absent on a normal run. The code followed the second, and a + seam test now pins that. The next contract should say which rule wins before + any seat starts. ## The coupling that will catch the next person adding a config key -`tests/test_docs_consistency.py` compiles `docs/env-vars.md` and `.env.example` -against `config._DEFAULTS` **in both directions**, and asserts two hard-coded -integers built as `f"**{len(_DEFAULTS)}** configuration keys"` and +`tests/test_docs_consistency.py` checks `docs/env-vars.md` and `.env.example` +against `config._DEFAULTS` **in both directions**. It also asserts two hard-coded +integers, built as `f"**{len(_DEFAULTS)}** configuration keys"` and `f"for {len(_DEFAULTS)+len(_LEGACY_ENV_ALIASES)} accepted variable names"`. -So a new config key is not a source change — it is an atomic four-surface change: -`_DEFAULTS`, the `config.py` docstring, `.env.example`, and `docs/env-vars.md` -including its counts and its `Per-Forge Auth (N)` section heading. Adding three keys -here failed five tests until all four surfaces moved together. Current values: **33** -keys, **1** legacy alias, **34** accepted names. +So a new config key is not a source change. It is an atomic change across four +surfaces: `_DEFAULTS` plus the `_INT_KEYS` / `_FLOAT_KEYS` / `_RANGES` / +`_CHOICE_KEYS` tables, the `config.py` docstring, `.env.example`, and +`docs/env-vars.md`, including its counts and its per-section headings. 0.14.0 +added 19 keys this way. Current values: **55** keys, **1** legacy alias, **56** +accepted names. ## Release shape (follow this next time) +How 0.14.0 was built: + +1. **Foundation.** Seats lay the shared seams every feature needs, each with a + placeholder body that fails closed. Nothing user-visible lands here. +2. **Wave 1.** One seat per issue runs in parallel, each in its own worktree + with a disjoint file list. A seat fills a placeholder; it does not add a seam. +3. **Wave 2.** Next come the pieces that needed two wave-1 bodies in place (the + replay CLI, replay over Azure DevOps, the second CLI backend) and the forge + fixes wave 1 surfaced. +4. **One integration gate per merge.** Each seat branch merges into + `release/X.Y.Z` on its own, and a merge stays only if the full + `uv run pytest` and `uv run ruff check src tests` pass on the merged tree. +5. **REL.** Parallel seats sweep stale docs, add cross-seat seam tests, and + write the version bump, the CHANGELOG and this file. Read-only live checks + follow against public PRs and real CLIs (see "Live checks" below). + +Cutting the release: + ```bash -uv build # produces BOTH sdist and wheel -gh release upload vX.Y.Z dist/prxref-X.Y.Z.tar.gz dist/prxref-X.Y.Z-py3-none-any.whl +# bump pyproject.toml and src/prxref/__init__.py, then: +uv lock # uv.lock carries the version too +git tag vX.Y.Z && git push origin vX.Y.Z ``` -Both assets matter: the v0.4.0 release ships both, and at least one consumer updates -itself with `gh release download --pattern '*.tar.gz'`, which does **not** match -GitHub's auto-generated source archive.

If a comment POST commits server-side and - the response is lost to a 502/504 or a read timeout, urllib3 re-sends it and the - comment is duplicated. The fix is to drop the write verbs from `allowed_methods` - and let the caller decide, but it changes retry behaviour for every forge. -- **Comment listings are capped and the cap is silent.** Bitbucket Server reads - 5 x 100 activities (`bitbucket_server.py:17-18,267`) and Bitbucket Cloud 5 x 100 - comments (`bitbucket.py:216-220`); GitLab reads a single page of 50 - (`gitlab.py:232,321`) and GitHub a single unparameterised page, so 30 - (`github.py:124,167`). Past the cap `list_threads` under-reports and `post_summary` - can miss its own `` and post a second summary. Server is the - *most* thorough of the four here, not the least. A shared paging helper with an - explicit "truncated" signal would fix all four at once. -- **A failed comment-listing read is treated as "no summary exists".** In - `post_summary`, a listing that errors leaves the existing-summary handle unset and - control falls through to the create-a-new-comment POST: - `bitbucket_server.py:310-311` then `:324`, and `gitlab.py:241-242` then `:254`. - GitHub has no `try` at all — a transport error propagates — but a non-`ok` - response takes the same fall-through (`github.py:125` -> `:139`). Bitbucket Cloud - is furthest from correct: `post_summary` (`bitbucket.py:165`) never looks for an - existing summary, so it posts a duplicate on *every* re-review. Distinguishing - "read failed" from "nothing found" and skipping the post is the fix, and it is the - same three-line change in each adapter. -- ~~**Move the dev tools to a dependency group.**~~ **Done** — the dev tools moved - from `[project.optional-dependencies] dev` to `[dependency-groups] dev`, so the bare - `uv run pytest` and `uv run ruff check` work on a cold checkout and the `--extra dev` - form is gone from CI and every doc. The behaviour change was accepted deliberately: - dependency groups are not published in package metadata, so `pip install prxref[dev]` - no longer resolves the tools. See the `Unreleased` section of `CHANGELOG.md`. - -- **`origin/feat/bitbucket-server-forge` can be deleted** once you are satisfied with - v0.5.0.

Without a ticket, or with an empty one, every finding is `unknown`, and so is any answer from the model other than exactly one of those three words. Scope is advisory only: it never changes a finding's severity or confidence, the verdict, the error cap, or `PRXREF_FAIL_ON`. The `outofscope` severity is unrelated and only means minor. How a scope shows on a posted comment is covered in [Finding Markers](#finding-markers). + +**How the ticket reaches the model.** The ticket text goes into the user prompt of every chunk worker and of the whole-PR sweep, under a `### Ticket context` heading. It sits inside a code fence it cannot close, with a line telling the model that it is data, not instructions. The request to add a `scope` to every finding is prxref's own policy, so it goes into the system prompt instead. While that request is in the prompt, the example finding under `## Output Format` in the worker and sweep prompts also carries `"scope": "in"`, because a model that copies the example rather than following the instruction would otherwise never label scope; without a ticket, or with an empty one, the prompts are unchanged. `PRXREF_TICKET_CONTEXT_MAX_CHARS` (default `6000`) caps the text. A longer ticket is cut, and a line after the fence says how many of its characters are shown. Criteria past the cap are not in view, so they do not count toward the state above. + +**What is recorded.** The `ticket_context` key of `--format json` and the run's `ticket ok` trace event hold the path, the SHA-256 of the file's raw bytes, its length in characters, the cap, whether it was truncated, whether it has acceptance criteria, and whether it was empty. The `-v` line shows the path, the start of the SHA-256, the length, and the active findings' `in`/`out`/`unknown` counts. None of these ever holds the ticket text. The text does appear in the prompt files that `--trace-dir` writes (`chunk0.user.md`, `sweep.user.md`), so treat that directory like the ticket itself. + +**The webhook daemon ignores the file.** One file cannot describe every PR a daemon sees, so `prxref serve` never reads `PRXREF_TICKET_CONTEXT_FILE` and logs a warning once at startup when it is set. + +## Team Review Rules + +Give prxref your team's review checklist and every chunk worker and the whole-PR sweep review against it: + +```bash +prxref review --pr-url https://github.com/acme/widget/pull/42 --rules-file "$RUNNER_TEMP/prxref-rules.md" +``` + +- `--rules-file PATH`, or `PRXREF_REVIEW_RULES` for every run, names a Markdown or plain-text file.

Unset, nothing changes. +- Optional front matter can map your team's severity words onto prxref's tiers in a `severity:` block (`blocker: error`, `major: warning`, `nit: outofscope`). A mapped word the model writes anyway is rewritten before every quality pass, so it is never dropped as an invalid severity. Other front-matter keys are ignored, so a skill file works unmodified. +- `PRXREF_REVIEW_RULES_MAX_CHARS` (default `12000`) caps the body, with a warning when it truncates. The run record's `review_rules` carries the file's `sha256`, its character count, and the parsed map, never the rules text. It appears in `--format json`, the `-v` output, and the JSONL trace. +- A missing, unreadable, or malformed file exits `2` before any network call, naming `--rules-file` or `PRXREF_REVIEW_RULES`. + +**Read the rules from a trusted checkout, never from the PR under review.** In CI the workspace is usually the PR's own code, so a rules file inside it lets the PR rewrite its own review rules.

Given a PR's + own target and source commits, the result is the PR's diff. There is no raw text to + return unmodified: the diff is rebuilt as for **Diffs**, so it has no `index` lines or + function names after `@@`, every mode is `100644`, and a `similarity index` line + appears only for a pure rename.

An empty range returns empty text, which replay + reports as an error run. An HTTP or transport error raises, and so do a non-JSON + listing, any other failed blob fetch, and a listing longer than 50 pages. While the + adapter was designed, a prototype of this method returned a PR's own diff from a + public Azure DevOps Services project, and a probe there saw `true` leave out files + that `false` listed.

The one key it sends is `PRXREF_LLM_API_KEY`, as a bearer token to the `openai-compat` endpoint you configured. Every provider key lives behind that endpoint, in the provider SDK's own environment (`litellm`), or inside your own logged-in CLI (`claude-cli`, `kiro-cli`). A CLI backend hands its CLI the environment `prxref` was started with; `claude-cli` first removes a fixed list of credential-routing variable *names*, so the CLI falls back to its subscription login, and never reads their values. 2. **Fast Caller-Side Failover:** Fallback is implemented as a fast sequential loop over the model list. If a model encounters HTTP 429 (rate limit), HTTP >= 500 (server/upstream error), connection failures, or timeouts, the client immediately advances to the next model in the chain without same-model retries. --- @@ -14,7 +14,7 @@ The primary and default backend communicates via plain HTTP requests with any OpenAI-compatible `/v1/chat/completions` server — a hosted router (OpenRouter, Together, Groq), a self-hosted gateway such as `llm-ferry`, or a local runtime such as vLLM or Ollama. - **Default Backend Alias:** `PRXREF_LLM_BACKEND=openai-compat` (aliases: `ferry`, `http`). -- **Endpoint URL:** `PRXREF_LLM_BASE_URL=https://llm.example.com/v1`.

Each would move the call off your subscription login: an API key always wins in `-p` mode, a gateway token or base URL re-points the CLI, the three `USE_*` flags route it to a cloud provider, a profile selects an organization identity, and bare mode ignores the OAuth login. Only the names are removed; their values are never read. `CLAUDE_CODE_OAUTH_TOKEN`, `HOME` and `CLAUDE_CONFIG_DIR` are kept, because they are how the CLI finds your login. +- **Managed settings are out of prxref's reach.** An organization's managed `apiKeyHelper` or forced gateway still loads under `--setting-sources ""`.

The attribution and the logs name the model the CLI reports it ran, so an alias shows up as its full id. A model the CLI rejects as unknown (a 404, or its unrecognized-model marker on stderr) is skipped for the rest of the run, with one WARNING. +- **`kiro-cli`** takes the ids `kiro-cli chat --list-models` prints, such as `claude-haiku-4.5`. The model goes into the agent file because the v2 engine ignores `--model`: it warns `failed to set model … Method not found` and runs its `auto` model. Kiro does not report which model ran, so the attribution names the model you configured. An unknown id fails that model as `: prompt error: Internal error (possibly an unknown model; check kiro-cli chat --list-models)`. Because Kiro's error does not name the model, prxref does not skip it for the rest of the run: every call tries it again before moving on down the chain. + +### Concurrency and timeouts + +- `PRXREF_LLM_CLI_CONCURRENCY` (default `2`) caps the CLI processes one client runs at once. The review's workers queue for a free slot, and the wait does not count against the timeout. A subscription's rate window belongs to your account, so a higher cap spends it faster. +- `PRXREF_LLM_TIMEOUT` is each model's wall-clock deadline, and it includes the CLI's own start-up: about 2.3 s for `claude` on a tiny prompt whose model time was 1.4 s, and 3.6–6.7 s for `kiro-cli`, as observed while designing these backends. Live `kiro-cli` calls on 2026-09-23 were much slower, 24–27 s for a one-line prompt and 28–37 s for a review call, so for `kiro-cli` `120` is the floor, not a comfortable margin. The 45 s default is sized for HTTP; use `120` or more. A model that misses its deadline has its whole process group killed, the chain moves on, and the review's zero-context retry applies exactly as it does over HTTP. + +### Tokens, cost and credits + +- **`claude-cli`** counts cache-creation and cache-read tokens as input tokens, because that is prompt the model read. +- **`kiro-cli`** reports no token counts, so every Kiro call counts `0` tokens and the attribution reads `0 tok`.

It is +not the `outofscope` severity either, which only means minor.

The identity used to + re-derive the chunk/sweep boundary across the gate includes `scope`, so + neither copy's scope ends up on the other. +- **It orders the inline batch within a severity.** When + `PRXREF_MAX_INLINE_COMMENTS` leaves room for only some findings, severity + decides first.

A file baked into + the runner image, or one from your CI's secure-files store, works too. + +An absolute path outside the working directory, like the two above, is read +as given. A path **inside** the working directory must still resolve inside +it once its symlinks are followed, so a PR that commits +`.prxref/rules.md -> /some/other/file` gets a configuration error rather than +a read of that file. + +**The residual risk.** A PR that can edit the pipeline definition itself can +change anything the pipeline does, the rules included. Protect the pipeline +files with required review (for example `CODEOWNERS`), or run prxref as the +webhook daemon, whose configuration no PR can reach. + +## The webhook daemon + +`prxref serve` reads `PRXREF_REVIEW_RULES` from its own environment and +re-reads the file for every review.
