fix(brain): move the wikilink strip into WriteNote/UpdateNote

The BrainStore is not the only door. POST /write — the HTTP path CLAUDE.md hands to curl and scripts — calls api.WriteNote directly, so the strip shipped one commit ago covered brain_write and capture while leaving the raw door ungated. A gate one door wide is not a gate. The BrainStore keeps its own call so it can still report Ref.Unlinked to the MCP caller; running the strip twice is a no-op on content the primitive has already cleaned.

+
+```
+/plugin marketplace add https://git.d-ma.be/mathias/skills.git

+```
+
+Skills are **namespaced** under Claude Code: load `tdd` as `skills:tdd`. The trigger table below uses bare names — prefix them.
+
+**Crush, Pi and OpenCode** have no plugin system and are wired by `install.sh` as one directory symlink per harness via `~/.agents/skills`. Do not clone the checkout into `~/dev`: that folder is iCloud-shared between the Macs and spans two path roots (`/Users/mathias` vs `/home/mathias` on koala), so a checkout there is a git working tree with two concurrent writers, and any absolute symlink stored in it is broken on one side by construction (skills#23). Leave `SKILLS_CHECKOUT_DIR` at its host-local default.

+**Claude Code** installs the repo as a plugin from the marketplace the same repo hosts. That path also carries the `secret-guard` and `pre-task-ritual` hooks and the brain/gitea/infra MCP servers, which symlinks cannot:
+
+```
+/plugin marketplace add https://git.d-ma.be/mathias/skills.git
+/plugin install skills@mathias
+```
+
+Skills are **namespaced** under Claude Code: load `tdd` as `skills:tdd`. The trigger table below uses bare names — prefix them.
+
+**Crush, Pi and OpenCode** have no plugin system and are wired by `install.sh` as one directory symlink per harness via `~/.agents/skills`. Do not clone the checkout into `~/dev`: that folder is iCloud-shared between the Macs and spans two path roots (`/Users/mathias` vs `/home/mathias` on koala), so a checkout there is a git working tree with two concurrent writers, and any absolute symlink stored in it is broken on one side by construction (skills#23). Leave `SKILLS_CHECKOUT_DIR` at its host-local default.
+
+Check a host with `task doctor` in the skills repo; it also runs automatically at session start via the plugin.

-## Ingest revises, it does not overwrite
-
-Re-ingesting a source **merges into the page already on disk** rather than
-replacing it. Previously the write was unconditional, so a second ingest of the
-same source discarded everything accumulated since — including hand-written
-sections.
-
-The merge is deliberately asymmetric in the existing page's favour:
-
-| On the page | In the fresh extraction | Result |
-|---|---|---|
-| a section | the same section | **the on-disk version wins** |
-| — | a new section | added |
-| a bullet list (`Sources`, `Key Claims`, …) | more bullets | unioned, no duplicates |
-| an append section (`Open Questions`, `Updates`, …) | more lines | only genuinely new lines appended |
-| frontmatter | frontmatter | **the on-disk frontmatter wins** |
-
-So an extraction can add to a note but never silently rewrite what a human put
-there, which is what makes it safe to run on every ingest rather than behind a
-review gate.
-
-Re-ingesting unchanged content is **byte-identical** — no diff, so brain-sync
-does not commit noise that hides real edits.
-
-Two fields are **generator-owned** and do get refreshed on a revise:
-`last_updated` and `source_hash`. Everything else on disk wins. The boundary is
-an explicit allowlist, so a field nobody has thought about stays human-owned.
-
-### Disagreement is reported, not resolved
-
-When the fresh extraction produces a *different version* of a section that
-already exists, the on-disk version still wins — but the run now says so:
-
-```
-wiki/sources/shape-up.md: source now disagrees on section "Summary" — on-disk version kept
-```
-
-That line lands in `log.md` with the rest of the run's warnings. Without it, "the
-source is unchanged" and "the source changed its mind and we ignored it" look
-identical from the outside.
-
-This is deliberately **textual** disagreement, not semantic contradiction: cheap,
-deterministic, no model on the write path. Deciding whether a disagreement is a
-genuine contradiction stays with the Judge-gated `brain-enrich` pass, which is
-approval-gated by design. Detection here, adjudication there.
-
-## Re-ingesting an unchanged source is skipped
-
-Ingest stores `source_hash` — sha256 of the ingested **body**, frontmatter
-excluded — on the source page. A later ingest of the same source compares it
-first and skips extraction entirely when it matches, reporting the skip rather
-than doing it silently.
-
-Body-only is deliberate: a re-crawl that stamps a new fetch date has not changed
-the source, and treating that as drift would re-extract the corpus every time a
-crawler ran. A missing or unreadable hash always means "extract" — a missed skip
-costs one extraction, a wrong skip loses an update.

POST /write — the HTTP path CLAUDE.md hands to curl and scripts — calls api.WriteNote directly, so the strip shipped one commit ago covered brain_write and capture while leaving the raw door ungated. A gate one door wide is not a gate. The BrainStore keeps its own call so it can still report Ref.Unlinked to the MCP caller; running the strip twice is a no-op on content the primitive has already cleaned.

The brain-audit digest grew 19 -> 63 high findings between 2026-08-26 and 2026-09-16; 53 of the 63 were exactly this, and none are fixable by brain-gardener's BrokenLinkFixer, which only repoints edit-distance-1 renames. There is no target to repoint to. StripUnresolvedLinks resolves each link against knowledge/ + wiki/ using brain-gardener's own resolver semantics (bare slug or wing/hall/slug path form, code spans excluded) and unwraps the misses to plain text, reporting them as Ref.Unlinked / the MCP `unlinked` field. Unwrap rather than reject: a refused write on claudewatcher's unattended ingest path is a lost learning, and the author's words are worth keeping even when the link is not. An empty corpus is a no-op, so a misconfigured brainDir cannot strip every link in a note. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>	2026-09-16 23:53:42 +02:00
mathiasandClaude Opus 5	25b79f057e	feat(claudewatcher): exclude whole project directories from ingestion CI / Mirror to GitHub (push) Successful in 4s Details CI / Lint / Test / Vet (push) Successful in 1m20s Details CLAUDE_INGEST_SKIP_PROJECTS takes filepath.Match globs tested against the project directory NAME, and a matching directory is skipped during the directory WALK — so its files are never opened and their content never enters the process. That is a stronger property than filtering after reading, and the difference is observable: without SkipDir, WalkDir lists the directory's entries, and an unreadable one aborts the entire walk, silently stopping ingestion for every other project. Globs rather than exact names because a project directory is derived from the session's working directory, so a git worktree yields an ephemeral name no exact-match list could keep up with. An unparseable pattern refuses to run. filepath.Match returns an error ALONGSIDE a false match, so a bad pattern checked per-file would ingest the directory while the log complained — the failure nobody notices. Validated once, up front, in both entry points. This complements the client-name scrubber rather than replacing it. The scrubber drops individual turns whose content matches a client identity; this excludes whole workspaces whose content is confidential in ways no pattern reliably recognises. Learnings from excluded sessions are captured deliberately through the session-close ritual instead. Recorded caveat: the project directory reflects the session's working directory, NOT the repositories it touches. A session run from ~/dev that reads an excluded repo is not excluded by this. The scrubber remains the control for content; this is a control for workspaces. A mutation test earned the strongest assertion here: the original tests could not distinguish SkipDir from filtering after the walk, because neither opens files. The unreadable-directory test can.

mathias	47bbac4b9f	revert(lint): back out the canonical .golangci.yml adoption — repo has a nested module CI / Lint / Test / Vet (push) Successful in 30s Details CI / Mirror to GitHub (push) Successful in 3s Details Adopting it turned CI red, and my pre-push verification missed why: `golangci-lint run ./...` does NOT traverse into nested Go modules. This repo has two — ./go.mod and ./ingestion/go.mod. I linted the root (0 issues, which CI reproduces exactly) and never linted ingestion/, which has 3 findings: ingestion/internal/audit/degrading.go:81 missing case capture.AuditCentral (exhaustive) ingestion/internal/capture/entities.go:37 missing case capture.ZoneUnknown (exhaustive) ingestion/internal/mcp/handlers.go:29 var int_ should be int (revive) Those are behavioural questions and a rename, not formatting — the same class of finding that kept cad, dispatch, ingestion-svc, dma-cli and email-triage-agent out of the earlier waves. Consistent with that, this repo goes back in the queue rather than being force-fitted now. The gofumpt formatting from the same commit is kept: it is independently correct and already green. Verification method corrected going forward: a repo with nested modules must be linted per module, not once from the root.	2026-09-05 14:47:39 +02:00
mathias	8a27ead91c	chore(lint): adopt the canonical .golangci.yml from infra/ci-templates CI / Mirror to GitHub (push) Skipped Details CI / Lint / Test / Vet (push) Failing after 12s Details Canonical lives at infra ci-templates/golangci.yml, distributed by the infra#309 pattern: byte-identical copies, checksum drift gate in infra. Do not edit this file here -- edit the canonical and run `task ci:sync`. Verified locally before pushing, not pushed-and-hoped: golangci-lint v2.11.4 against a Go 1.26.1 toolchain (matching CI) reports 0 issues here. Also applies gofumpt, which this config enables and the golangci-lint v2 default set does not check at all. That gap is why the drift was invisible: earlier passes ran gofmt, which is weaker. Mechanical, deterministic, build+vet verified.	2026-09-05 14:42:59 +02:00
mathias	1a9be0cfb1	style: apply gofmt CI / Lint / Test / Vet (push) Successful in 30s Details CI / Mirror to GitHub (push) Successful in 4s Details Estate-wide consolidation pass. golangci-lint v2 default set enables NO formatter, so gofmt drift accumulated silently across the estate -- 8 repos were carrying it, this one included. Same hole that let two files rot in dma-cli until they were found by hand (dma-cli#12). Mechanical and deterministic: `gofmt -w`, nothing hand-edited. Verified before commit -- gofmt -l now reports 0, go build and go vet both pass. Clears this repo to adopt the canonical .golangci.yml (infra ci-templates/golangci.yml, infra#309 pattern) in a later wave.	2026-09-05 12:40:34 +02:00
mathias	dc2265da0b	fix(ci): skip context:sync's drift check under CI, matching dma-cli/gitea-mcp CI / Mirror to GitHub (push) Successful in 4s Details CI / Lint / Test / Vet (push) Successful in 1m22s Details hyperguild's Taskfile ran context:sync unconditionally in 'check', with no guard for the CI runner having no ancestor .context/AGENT.md. That made it silently regenerate AGENTS.md and .context/system-prompt.txt from project context alone (82 lines vs. the committed, correct 430) and then fail its own drift assertion against that wrong baseline every run -- a false positive, not real drift. Verified locally: syncing with the real root context reproduces the committed 430-line files byte for byte; syncing without it (as CI does) produces the shorter fallback that triggered this. Same guard dma-cli and gitea-mcp already carry, same rationale: drift is now caught either on a developer machine or by infra's estate-wide context-sync-drift CronJob (ADR-0019), which does have canonical access.	2026-09-05 11:36:45 +02:00
mathias	c176b71b3d	fix(context): AGENTS.md/system-prompt.txt committed in `4e8bdc1` were missing root content CI / Lint / Test / Vet (push) Failing after 2s Details CI / Mirror to GitHub (push) Skipped Details The previous commit's regeneration produced AGENTS.md byte-identical to CLAUDE.md (82 lines, project-only) instead of the expected root+project concatenation (430 lines) -- root_block() rendered empty despite the run's own log claiming "Root context: .../AGENT.md" and "AGENTS.md (root + project...)". Not reproduced: re-running the identical command (ROOT_CONTEXT=.../AGENT.md bash scripts/context-sync.sh) immediately after produces the correct 430-line output every time. Whatever caused the original miss was transient and is not diagnosed here -- flagging rather than asserting a cause I have not confirmed. Caught by the estate-wide context-sync-drift gate's own verification run, not by trusting the fix commit. Regenerated fresh and confirmed root content is present before committing this time.	2026-09-05 08:36:03 +02:00

mathias	42235dcb6a	fix(scan): an allowlist was hiding a real Gitea PAT on a false justification CI / Lint / Test / Vet (push) Successful in 32s Details CI / Mirror to GitHub (push) Successful in 5s Details infra#344. The removed block suppressed docs/superpowers/plans/2026-04-22-phase4-attempt-wiring.md, and its description stated why: "Literal placeholder word REDACTED matched as if it were a token (verified 2026-08-04: extracted Secret == 'REDACTED' exactly, gitleaks' curl-auth-header rule matched the placeholder text itself, not a real credential)" That is not what the file contained. Line 1054 carried a real 40-character hex Gitea PAT in an `Authorization: token ...` header — not the eight-character word REDACTED. Whether the file changed after the check or the check was wrong, the justification has been guarding the wrong thing since. Confirmed dead by side-effect before touching it, never by printing it: `GET /api/v1/user` with that token returns 401. So there is nothing to rotate. It is redacted here anyway, because a dead credential in a doc is still a working example of how to write a live one, and git history keeps the original either way. Two independent failures had to line up, which is the same pair as infra#256: 1. The `paths` clause made the block far broader than its description. gitleaks ORs global allowlist clauses and ignores `condition = "AND"`, so the ENTIRE file was immune — a live token pasted into that doc tomorrow would have been suppressed on the strength of a note about a different value. 2. The justification was never re-checked against the file it justifies. With the token redacted the allowlist has nothing left to do, so it is deleted rather than narrowed. Repo scans clean, and a planted live-shaped credential in that same file is now caught. Refs: mathias/infra#344, mathias/infra#256, mathias/infra#317	2026-08-31 07:24:07 +02:00
mathiasandClaude Sonnet 5	05330ad54a	feat(brain): add Gemini as brain_answer's third LLM tier CI / Lint / Test / Vet (push) Successful in 36s Details CI / Mirror to GitHub (push) Successful in 4s Details llm.Router was primary-then-fallback (berget -> iguana ollama). Both have failed together at least once in production (berget 5xx outage + a cold fallback model exceeding the shared timeout budget), leaving brain_answer/brain_classify fully down. Router gains an optional Tertiary *Client, tried only if both Primary and Fallback fail. Nil-safe — existing 2-tier deployments (no BRAIN_LLM_TERTIARY_URL) behave exactly as before. main.go wires it from BRAIN_LLM_TERTIARY_URL/MODEL + GEMINI_API_KEY, pointed at Google's OpenAI-compatible Gemini endpoint (generativelanguage.googleapis.com/v1beta/openai/) — llm.Client already speaks OpenAI-shaped chat-completions, so no new client type needed. Tests: TestRouter_FallsBackToTertiaryWhenPrimaryAndFallbackFail, TestRouter_TertiaryNotCalledWhenFallbackSucceeds, TestRouter_AllThreeFail, TestRouter_NilTertiary (2-tier backward-compat). Full suite green (both modules, -race), golangci-lint clean. Deployment env vars (infra repo, separate commit — GitOps, TBD there too): BRAIN_LLM_TERTIARY_URL, BRAIN_LLM_TERTIARY_MODEL, GEMINI_API_KEY secretRef.

mathias	692244d213	security: disposition the one historical gitleaks finding (infra#326) CI / Lint / Test / Vet (push) Successful in 31s Details CI / Mirror to GitHub (push) Successful in 3s Details A Gitea PAT was pasted into a CD-watching curl command in a 2026-04-22 planning doc (`c9310b10`, last_eight 3105a670). Verified dead before dispositioning it, rather than assuming: authenticating GET /api/v1/user with that exact value returns 401. It was almost certainly invalidated by the early-August rotation of the `mathias` PATs -- the same rotation whose fan-out caused infra#260, where CI's stale copies kept failing. So it was killed for unrelated reasons, by luck rather than by the leak being noticed. No rotation outstanding. `task security:gitleaks:history` now exits 0 here. Used .gitleaksignore (per-finding fingerprint) rather than a path allowlist in .gitleaks.toml: a path allowlist would also blind the working-tree scan that gates commits. Verified both directions -- history 1 -> 0, working tree still clean.	2026-08-29 10:04:11 +02:00
mathias	d98a305985	security(hooks): add local pre-commit gitleaks scan (infra#326) CI / Lint / Test / Vet (push) Successful in 1m33s Details CI / Mirror to GitHub (push) Successful in 4s Details task check -> security:gitleaks was already CI-enforced here, but that catches a leak after the push, not before -- exactly the gap infra#39's prevention checklist called out ("gitleaks pre-commit hook in both infra and hyperguild"), true for infra but not this repo. Mirrors infra's own .githooks/pre-commit, minus the YAML/image-tag checks that are infra-manifest-specific and don't apply here. Verified functionally, not just wired: staged a real high-entropy fake key and confirmed `git commit` is blocked by the hook (RuleID=generic-api-key); staged a well-known documented-example AWS key (AKIAIOSFODNN7EXAMPLE) first and confirmed gitleaks correctly passes it (it's not a real leak, and gitleaks' own default rules know that) -- worth recording since a naive fixture check would have looked like detection was broken.

mathiasandClaude Opus 5	670325e519	ci(deploy): refuse to patch a manifest with an empty IMAGE_TAG (infra#311) CI / Lint / Test / Vet (push) Successful in 39s Details CI / Mirror to GitHub (push) Successful in 4s Details On 2026-08-25 a deploy job ran with an empty IMAGE_TAG, wrote `image: localhost:5000/gitea-mcp:` into the infra repo and pushed it. That is invalid YAML, so Flux failed the ENTIRE apps Kustomization -- every app stopped reconciling for about an hour, including three unrelated deploys queued behind it. This job's existing check could not catch it. It greps for `image: <repo>:${IMAGE_TAG}` after the sed, and with IMAGE_TAG empty that pattern matches the corrupted line itself, so the verification passes because of the bug rather than despite it. Asserting the input up front is the fix: an empty tag now fails the job before anything is written, let alone committed.
