corebunch/instatic: technical due diligence, read from its repository

What Borehole read in corebunch/instatic's code and history at 2e6b426: its licence, security advisories, releases, review practice, tests, dependencies and operations. Every finding cites the file and line it rests on. The full report also covers the team and asks the questions the code cannot answer.

Architecture & Codebase — including AI provenance

strong
01.6

server/db/migrations-sqlite.ts is 1,530 lines, 13× this codebase's median file

adequate

The median source file here is 114 lines. 2 files exceed 1,140 lines, the largest being 1,530. Size is not a defect on its own — some problems genuinely live in one place — but these are where merge conflicts, review fatigue and single-owner knowledge concentrate, and they are the first thing that slows an inheriting engineer down.

Evidence
server/db/migrations-sqlite.ts:1 — 1,530 lines (13× median)
server/db/migrations-pg.ts:1 — 1,374 lines (12× median)

Engineering Process & SDLC Maturity

adequate
02.16

Tests are retried until they pass

adequate

The suite is configured to retry failing tests (playwright.config.ts). A retry turns a flaky test green without saying why it failed, so a green build means the tests passed eventually. Ask how many retries a typical run needs, and which tests need them.

Evidence
playwright.config.ts:19 — test retry
02.24

9% of recent commits change more than 2,000 lines

adequate

103 of 1091 commits in the last 24 months changed over 2,000 lines of code, not counting reformatting, renames, vendored or generated code. A change that size is rarely reviewed line by line. Ask how they were reviewed, and what made them that large.

Evidence
103 commits over 2,000 lines

Product & Engineering Maturity

strong

No finding.

Security & Reliability Posture

strong
05.3

85 dependencies float, and no lockfile is committed

adequate

Dependency versions are declared as ranges and no lockfile is committed, so a build today does not necessarily produce what a build last month produced. That matters twice over in a transaction: the thing being bought cannot be reproduced exactly, and a compromised upstream release arrives without anyone choosing to take it.

Evidence
package.json:6 — >=1.4.0 <1.5.0
package.json:63 — ^6.20.1
package.json:64 — ^6.3.1
package.json:65 — ^6.4.11
package.json:66 — ^6.2.5
05.27

The build runs third-party code it does not pin

adequate

5 third-party CI actions are referenced by a tag or branch rather than a commit, so they run whatever that tag points to on the day. Tags have been moved to malicious commits in real supply-chain attacks, and a piped script is whatever the server returns that minute. Pinning to a commit is the fix, and it is small.

Evidence
.github/workflows/ci.yml:28 — action pinned by tag
.github/workflows/release.yml:55 — action pinned by tag
05.48

10 places insert HTML from a variable without sanitising it

adequate

10 places set HTML from a value that is neither a literal nor passed through a sanitiser. Where the value can come from a user, that is stored cross-site scripting, and it is the first thing a buyer's security review looks for in a frontend.

Evidence
server/publish/holeRuntime.ts:28 — HTML from a variable
server/publish/holeRuntime.ts:41 — HTML from a variable
server/publish/loopRuntime.ts:70 — HTML from a variable
05.9

1 vendored component with no licence

adequate

Third-party code is committed into this repository without any statement of the terms it arrived under. Unknown terms are harder to deal with than inconvenient ones: an awkward licence can be complied with, an absent one cannot. Each of these needs its origin established before the code changes hands.

Evidence
vendor/pixel-art-icons — 423 tracked files, no licence file
05.65

3 advisories against this project in the last 24 months, 2 high or critical

adequate

The newest was published on 2026-11-03. A project that publishes advisories is telling its users about its fixes, and the count and pace say how much security work it carries. Whether 1 of them are fixed in the code you ship could not be told from this history: its version is only known to be at least 0.0.21. Answer lives in: the release you run, set against each fixed version.

Evidence
2026-11-03: GHSA-x5cc-8486-8qqx (moderate), fixed in 0.0.21: Authorization Bypass in the AI/MCP Content Read Tools Allows Reading Any User's Private Drafts and System-Table Rows
2026-11-03: GHSA-m425-wmrc-4v4v (high), fixed in 0.0.21: Authorization Bypass in PATCH /admin/api/cms/data/rows/:id/author Allows Reading Any System-Table Row and Reassigning Its Author
2026-11-03: CVE-2026-121458 (high): Instatic before 0.0.21 contains a missing authorization vulnerability in its AI/MCP content read tools that allows low-privileged authenticated users with ai.ch

Observability & Operations

adequate
06.1

No telemetry or error reporting is wired in anywhere

adequate

None of 2,800 readable files references an instrumentation, metrics or error-reporting library. If this system is in production, nobody learns that it broke from the system itself — they learn it from a customer. That is a reliability finding before it is an observability one.

Evidence
searched 2,800 tracked text files for 16 known instrumentation libraries; manifests for metrics, tracing and error-reporting families; locked dependencies for the packages that emit; 0 matched
06.2

No structured logging library is in use

adequate

Nothing references a structured logging library. Logs that are written to be read by a person are not searchable by a machine, which means incident response here is proportional to how well someone remembers the codebase rather than to what the tooling can find.

Evidence
searched 2,800 files for 10 structured logging libraries; 0 matched
06.9

No error reporter is wired in

adequate

Nothing in the service initialises an error reporter (Sentry, Rollbar, Bugsnag, Honeybadger or an APM agent). An exception in production reaches a person only if someone is reading the logs, which usually means a customer reports it first.

Evidence
no error reporter initialised
