In `@documentation/backend-specs.md`:
- Line 12: The /renew endpoint currently allows API key regeneration with only
an email, enabling unauthorized renewals; change the flow for the /renew route
to require strong verification: require the current API key (authenticate the
caller) via the existing auth middleware before allowing renewal, or implement a
secure email verification flow that sends a time-limited, single-use renewal
token/link to the email and only renews when that token is presented; add rate
limiting for the /renew route (e.g., 1 per 24h per email) and consider branching
for high-value accounts to require additional verification; update any handler
or controller for the "/renew" route to enforce these checks and log audit
events for renewals.
- Around line 23-27: Update the "API Security" section by adding a new "Rate
Limiting Strategy" subsection that specifies concrete limits per endpoint (e.g.,
uploads, retrievals, registrations), explicit windows for each limit (per
minute/hour/day), whether limits apply per-user (API key) or per-IP (or both)
for each endpoint, the exact rate-limit response format (HTTP status code,
headers like X-RateLimit-Limit, X-RateLimit-Remaining, X-RateLimit-Reset and
JSON body fields), and the behavior on violation (429 response, retry-after
header, optional backoff or temporary blocking); ensure this subsection sits
alongside the existing "Rate Limiting" bullet under the "API Security" heading
so implementers can copy these rules directly.
In `@tasks/backend/TASK-US-002-01-create-user-model.md`:
- Line 39: The api_key Field is declared with max_length=64 but the generated
key uses the prefix "ipfs_gw_" + secrets.token_hex(32) (72 chars); update the
api_key Field's max_length to at least 72 (I recommend 80 for headroom) and
update any other occurrences of this constraint (the referenced lines 72-79) so
they match; after changing the api_key Field, create and run the corresponding
DB migration to alter the column length so inserts won't fail.
In `@tasks/backend/TASK-US-005-02-implement-filebase-service.md`:
- Around line 286-294: The config currently defaults FILEBASE_ENDPOINT_URL,
FILEBASE_IPFS_API_KEY, FILEBASE_IPFS_API_SECRET, and FILEBASE_BUCKET_NAME to
empty strings which pushes errors to runtime; add startup validation that checks
these variables (FILEBASE_ENDPOINT_URL, FILEBASE_IPFS_API_KEY,
FILEBASE_IPFS_API_SECRET, FILEBASE_BUCKET_NAME) and raise a clear exception
(e.g., ValueError/ConfigError) if any required value is missing or empty, so the
application fails fast with a descriptive message; perform this validation in
the module that defines these constants or in the application initialization
path that imports them (e.g., config loader or init function).
- Around line 120-179: The upload_file method currently uses the raw filename as
the S3 key; sanitize and normalize the key before upload by removing path
separators and disallowed characters, enforcing a safe character whitelist
(alphanumerics, dashes, underscores, dots), and limiting length; prepend a UUID
(or secure random prefix) to the sanitized filename to avoid collisions and
overwrites, and use this sanitized_key when calling self.client.upload_fileobj
and when returning UploadResult(key=...). Ensure all references to filename in
head_object and logging use sanitized_key and that FILEBASE_BUCKET_NAME remains
unchanged.
- Around line 120-179: The upload_file implementation assumes the incoming
BinaryIO is seekable and calls file.seek() which will raise on non-seekable
streams; change upload_file to detect non-seekable streams (using
file.seekable()) and if not seekable, wrap the stream into a seekable buffer
(e.g., tempfile.SpooledTemporaryFile()) and copy the incoming data into it so
you can determine size and rewind before upload (use the buffered object's
seek/tell), or alternatively set size = None and update UploadResult to accept
Optional[int] and downstream callers to handle None; update references in
upload_file (file, filename, size, UploadResult) accordingly and ensure
metadata/ExtraArgs logic and head_object/CID handling remain the same when using
the buffered file.
In `@tasks/frontend/TASK-US-101-04-create-api-client.md`:
- Line 39: The code is reading the API key from localStorage via
localStorage.getItem("api_key") which exposes it to XSS; replace this
client-side storage with a secure approach: have the backend set the API token
in an httpOnly, Secure, SameSite cookie and change the client code that uses
apiKey to stop reading localStorage and instead make requests with fetch/axios
using credentials: 'include' (or withCredentials) so the server-side cookie is
sent automatically; alternatively implement a short-lived access token + refresh
token flow where only the refresh token is httpOnly and the frontend holds no
long-lived secret—update all references to apiKey/localStorage.getItem to use
the new mechanism and remove any code that persists credentials in localStorage.
- Line 58: Replace the direct window.location.href assignment in the interceptor
with a Next-friendly navigation signal: either dispatch a CustomEvent like
"auth:unauthorized" from the interceptor (so a top-level component/layout using
useRouter can listen for that event and call router.push('/login')), or reject
the request with a distinct error (e.g., Error('UNAUTHORIZED')) after clearing
localStorage so calling components (React Query onError handlers or hooks) can
detect that error and call router.push('/login'); update the interceptor code
path that currently does window.location.href = "/login" to implement one of
these two patterns.
- Around line 37-46: The request interceptor registered on
apiClient.interceptors.request.use reads localStorage directly which will throw
during SSR; update the interceptor (the function passed to
apiClient.interceptors.request.use) to first check for a browser environment
(e.g., typeof window !== "undefined" and window.localStorage) before calling
localStorage.getItem("api_key"), and only set config.headers["X-API-Key"] when
the check passes; keep the existing error handler and return config as before.
In `@user-stories/backend/US-002-database-models-migrations.md`:
- Around line 26-29: The ERD and docs currently show integer primary keys (e.g.,
"int id") while the technical notes require UUIDs; update the diagram and all
related field references (e.g., user_id, id columns, and foreign key labels) to
UUID, and align model/migration definitions to use UUID primary keys and UUID
foreign keys (ensure defaults like uuid_generate_v4() or the framework's UUID
generator are specified). Also update any prose in the markdown that mentions
"int id" to "UUID" so the documentation, ERD, and model/migration names (e.g.,
user_id, <entity>_id) are consistent. Ensure foreign key constraints and sample
queries in the doc reflect UUID types.
In `@user-stories/backend/US-004-api-key-management.md`:
- Around line 19-24: The renew flow currently trusts only an email; change the
API key renewal endpoint (e.g., renew / renewApiKey handler) to require a secure
verification: either an authenticated session, a time-limited one-time token
(OTP) sent to the user’s email and verified by the renew handler, or a signed
verification link containing a nonce validated server-side before issuing a new
key; ensure the old key is invalidated, the action is recorded in AuditLog (use
the same AuditLog entry creation used by createApiKey/revokeApiKey), and trigger
the email notification path after successful renewal; update any renew-related
validation logic to reject requests that lack the OTP/session/signed nonce.
In `@user-stories/backend/US-010-audit-logging.md`:
- Line 16: Update the audit logging spec to address IP privacy: in the "Details
field" add a clear data retention policy (e.g., IP_RETENTION_DAYS = 90) and a
legal-basis statement (e.g., "legitimate interest for security"); add an option
to anonymize/hash IPs for non-critical logs (e.g., ANONYMIZE_IPS flag and
describe hashing algorithm/entropy), require an admin workflow and API support
to honor user deletion requests for IP data, and add a note to
registration/terms that IP logging is performed; ensure the spec indicates
whether raw IPs are stored (retain_raw_ips boolean) and how/when raw→hashed
migration or deletion occurs.
In `@user-stories/frontend/US-104-login-dashboard.md`:
- Line 32: The doc suggests "Store API key in secure HTTP-only context or
encrypted localStorage", which is insecure; update the guidance to recommend
using HTTP-only, Secure, SameSite cookies for session tokens (backend validates
API key once and issues short-lived session token) as the primary option, and
add two alternatives: (a) keep API keys only in memory (React state/context) for
per-session use requiring re-entry after refresh, and (b) implement
OAuth2/token-based auth with refresh tokens stored in HTTP-only cookies; replace
the phrase "encrypted localStorage" and explicitly list these three options
(HTTP-only cookie flow, in-memory per-session storage, OAuth2) with brief
implementation notes for backend validation and token lifetimes.

61-61:⚠️ Potential issue | 🟡 MinorInconsistency: "login" action type without corresponding endpoint.
The action types table includes "login" (line 61), but the backend specifications don't define a login endpoint—authentication is API key-based. This creates confusion about the authentication model.
Recommendation: Either:
- Remove "login" from action types if API keys are the only authentication method, OR
- Clarify if there's a planned session-based login flow that uses API keys for initial authentication

- Documentation polish and updates
- Unexpected technical challenges (especially with Filebase API integration)
A more realistic estimate would be 250-300 hours (6-8 weeks) for a production-ready system. Consider adding a contingency buffer of 25-30% to the estimates.

Security issue: /renew endpoint design enables unauthorized API key renewal.
The specification states that the /renew endpoint only requires an email address to send a new API key. This design allows anyone who knows a user's email to trigger API key regeneration, potentially:
- Causing denial of service by invalidating the user's current key
- Creating confusion and support burden
- Enabling email enumeration attacks
Recommendations:
- Require the current (possibly compromised) API key for authentication before renewal
- Implement a secure email verification flow (send a time-limited renewal link)
- Add rate limiting specifically for this endpoint (e.g., 1 renewal per 24 hours per email)
- Consider requiring additional verification for high-value accounts
🤖 Prompt for AI Agents
In `@documentation/backend-specs.md` at line 12, The /renew endpoint currently
allows API key regeneration with only an email, enabling unauthorized renewals;
change the flow for the /renew route to require strong verification: require the
current API key (authenticate the caller) via the existing auth middleware
before allowing renewal, or implement a secure email verification flow that
sends a time-limited, single-use renewal token/link to the email and only renews
when that token is presented; add rate limiting for the /renew route (e.g., 1
per 24h per email) and consider branching for high-value accounts to require
additional verification; update any handler or controller for the "/renew" route
to enforce these checks and log audit events for renewals.

Specify rate limiting details for better implementation guidance.
While rate limiting is mentioned as a requirement, the specification lacks concrete details that would guide implementation:
- Rate limits per endpoint (e.g., uploads, retrievals, registrations)
- Rate limit windows (per minute/hour/day)
- Per-user vs. per-IP rate limiting strategy
- Rate limit response format (remaining quota, reset time)
- Handling of rate limit violations
Consider adding a "Rate Limiting Strategy" subsection with these details to ensure consistent implementation across endpoints.

Critical: API key length exceeds max_length constraint.
The api_key field is defined with max_length=64, but the generated API key will be 72 characters long:
- Prefix
"ipfs_gw_"= 8 characters secrets.token_hex(32)= 64 hexadecimal characters- Total = 72 characters
This will cause database insertion failures or silent truncation.

Python file-like object seekable streams BinaryIO seek non-seekable
💡 Result:
Seekability is a runtime property of file-like objects (not guaranteed by BinaryIO)
- In Python’s I/O model, a stream is seekable iff
obj.seekable()returnsTrue. If it’sFalse, thenseek(),tell(), andtruncate()are expected to raiseOSError. [1] typing.BinaryIOis a broad type (“types of I/O streams such as returned byopen()”), and it is not a protocol with strict guarantees—so aBinaryIOvalue may still be non-seekable (e.g., sockets / HTTP responses). [2]
Practical pattern: check seekable() and fall back to buffering
from typing import BinaryIO
import io
import tempfile
def ensure_seekable(src: BinaryIO, *, max_mem: int = 8 * 1024 * 1024) -> BinaryIO:
if getattr(src, "seekable", lambda: False)():
return src
# Option A: memory+disk spooling (best general-purpose)
tmp = tempfile.SpooledTemporaryFile(max_size=max_mem, mode="w+b") # seekable
while True:
chunk = src.read(1024 * 1024)
if not chunk:
break
tmp.write(chunk)
tmp.seek(0)
return tmp
# Option B (if you KNOW it's small): return io.BytesIO(src.read())Why SpooledTemporaryFile: it keeps data in memory up to max_size, then transparently rolls over to disk, and behaves like a normal seekable file. [3]
“Can I wrap a non-seekable stream to make it seekable?”
Not in a magic way. If the underlying source is inherently sequential (socket/HTTP), you generally must buffer/copy somewhere (memory or a temp file) to support seeking. This is a common issue with HTTP response objects. [4]
Note on io.BufferedReader docs vs reality
Some docs describe io.BufferedReader as giving higher-level access to a readable “non-seekable” raw stream, but in practice it can wrap seekable streams too; its seekable() just reflects the underlying stream. [5]
Sources: [1] io.IOBase.seekable() behavior [1], typing.BinaryIO scope/non-protocol note [2], tempfile.SpooledTemporaryFile behavior [3], non-seekable HTTPResponse / buffering requirement [4], BufferedReader seekability discussion [5].
Handle non-seekable upload streams with buffering.
file.seek() will raise OSError on non-seekable streams (HTTP responses, request bodies, sockets) since BinaryIO does not guarantee seekability. The guard with seekable() prevents crashes, but still leaves the stream unhandled. Instead, convert non-seekable streams to seekable ones using tempfile.SpooledTemporaryFile() to buffer in memory/disk, or accept that size cannot be determined and handle None in downstream code.
💡 Recommended approach
+ # Convert non-seekable streams to seekable via buffering
+ if hasattr(file, "seekable") and not file.seekable():
+ import tempfile
+ buffered = tempfile.SpooledTemporaryFile(max_size=8*1024*1024)
+ while True:
+ chunk = file.read(1024*1024)
+ if not chunk:
+ break
+ buffered.write(chunk)
+ buffered.seek(0)
+ file = buffered
+
# Get file size
file.seek(0, 2) # Seek to end
size = file.tell()
file.seek(0) # Seek back to startAlternatively, if seeking is not critical, set size = None for non-seekable streams and update UploadResult to accept optional size.

Defaulting credentials/bucket to empty strings defers failures to runtime with confusing errors. Recommend validating config on startup and raising a clear exception if required values are missing.

Use Next.js router instead of direct window.location manipulation.
Direct assignment to window.location.href bypasses Next.js's client-side routing, causing a full page reload and losing client-side state. Use the Next.js useRouter hook or programmatic navigation instead.
💡 Recommended approach
Since interceptors cannot directly access React hooks, consider one of these patterns:
Option 1: Emit a custom event that a component listens for:
// In interceptor
window.dispatchEvent(new CustomEvent('auth:unauthorized'));
// In a layout component with useRouter
useEffect(() => {
const handleUnauth = () => router.push('/login');
window.addEventListener('auth:unauthorized', handleUnauth);
return () => window.removeEventListener('auth:unauthorized', handleUnauth);
}, [router]);Option 2: Return a specific error that components handle:
// In interceptor - just reject with a custom error
if (error.response?.status === 401) {
localStorage.removeItem("api_key");
localStorage.removeItem("user_email");
return Promise.reject(new Error('UNAUTHORIZED'));
}
// In components using React Query
onError: (error) => {
if (error.message === 'UNAUTHORIZED') {
router.push('/login');
}

In `@tasks/frontend/TASK-US-101-04-create-api-client.md` at line 58, Replace the
direct window.location.href assignment in the interceptor with a Next-friendly
navigation signal: either dispatch a CustomEvent like "auth:unauthorized" from
the interceptor (so a top-level component/layout using useRouter can listen for
that event and call router.push('/login')), or reject the request with a
distinct error (e.g., Error('UNAUTHORIZED')) after clearing localStorage so
calling components (React Query onError handlers or hooks) can detect that error
and call router.push('/login'); update the interceptor code path that currently
does window.location.href = "/login" to implement one of these two patterns.

Resolve UUID vs. integer ID inconsistency.
The technical notes specify UUID primary keys, but the ERD shows int id. Please update the diagram (and any related fields like user_id) to UUID to avoid divergent implementations.

29, The ERD and docs currently show integer primary keys (e.g., "int id") while
the technical notes require UUIDs; update the diagram and all related field
references (e.g., user_id, id columns, and foreign key labels) to UUID, and
align model/migration definitions to use UUID primary keys and UUID foreign keys
(ensure defaults like uuid_generate_v4() or the framework's UUID generator are
specified). Also update any prose in the markdown that mentions "int id" to
"UUID" so the documentation, ERD, and model/migration names (e.g., user_id,
<entity>_id) are consistent. Ensure foreign key constraints and sample queries
in the doc reflect UUID types.

Require a secure verification step for API key renewal.
Renewal based solely on email enables account takeover (anyone can submit another user’s email). Consider requiring an authenticated session, a one-time token sent to email, or a signed verification link before issuing a new key.

Consider data privacy implications of IP address logging.
The specification requires logging IP addresses (line 16, 43) for security analysis, which has privacy and compliance implications:
GDPR/CCPA Considerations:
- IP addresses are personally identifiable information (PII)
- Requires clear data retention and deletion policies
- Users may need the ability to request IP data deletion
Recommendations:
- Add a data retention policy (e.g., "IP addresses retained for 90 days")
- Document the legal basis for IP logging (legitimate interest for security)
- Consider IP anonymization/hashing for non-critical logs
- Add IP logging disclosure to user registration terms

logging spec to address IP privacy: in the "Details field" add a clear data
retention policy (e.g., IP_RETENTION_DAYS = 90) and a legal-basis statement
(e.g., "legitimate interest for security"); add an option to anonymize/hash IPs
for non-critical logs (e.g., ANONYMIZE_IPS flag and describe hashing
algorithm/entropy), require an admin workflow and API support to honor user
deletion requests for IP data, and add a note to registration/terms that IP
logging is performed; ensure the spec indicates whether raw IPs are stored
(retain_raw_ips boolean) and how/when raw→hashed migration or deletion occurs.

| ## Technical Notes | ||
| - Store API key in secure HTTP-only context or encrypted localStorage |
There was a problem hiding this comment.
Security concern: Storing API keys in localStorage is a risk.
The technical note suggests storing API keys in "encrypted localStorage", but this approach is vulnerable to XSS attacks. localStorage is accessible to any JavaScript running on the page, making it unsuitable for sensitive credentials like API keys.
Consider these alternatives:
- Option 1 (Recommended): Use HTTP-only, Secure, SameSite cookies for session tokens after initial API key authentication. The backend validates the API key once and issues a short-lived session token.
- Option 2: If direct API key usage is required, prompt users to enter their API key per session and store it only in memory (React state/context), requiring re-entry after page refresh.
- Option 3: Implement OAuth2 or similar token-based authentication with refresh tokens stored in HTTP-only cookies.

In `@user-stories/frontend/US-104-login-dashboard.md` at line 32, The doc suggests
"Store API key in secure HTTP-only context or encrypted localStorage", which is
insecure; update the guidance to recommend using HTTP-only, Secure, SameSite
cookies for session tokens (backend validates API key once and issues
short-lived session token) as the primary option, and add two alternatives: (a)
keep API keys only in memory (React state/context) for per-session use requiring
re-entry after refresh, and (b) implement OAuth2/token-based auth with refresh
tokens stored in HTTP-only cookies; replace the phrase "encrypted localStorage"
and explicitly list these three options (HTTP-only cookie flow, in-memory
per-session storage, OAuth2) with brief implementation notes for backend
validation and token lifetimes.
